Recently, a senior school girl in the Sujiatun District of Shenyang City was burned with a burst of electric heating bag. In hospitals, such incidents as electric heating and electric heat scald were widespread. After investigating the market, the relevant departments found that most of the hot water bags and electric heaters were in compliance with national standards. The main cause of electric leakage accidents was the presence of environmental leakage accidents or improper use of some households, such as ungrounded lines or poor grounding. Therefore, the correct use of auxiliary heating tools is particularly important. The reason why an electric heating bag uses an electric hot water bottle to cause an explosion is very simple. Water heating generates air and the air is very hot and swellable. Therefore, exhaust gas is the most reliable safety solution. In addition also need to pay attention to the following matters: 1, before the application of dry cloth dry carefully wipe the water left on the bag when filling the water to ensure dry charging. 2. Do not turn over the bag body when charging so that the power jack is facing down. Do not touch the power cord with water. Do not carry the electric heating bag by the person and hold the battery. 3. It is forbidden to charge under the condition of insufficient water injection or exhaust air. 4. Be careful not to let the water flow into the power hole of the bag body, otherwise it will cause a short circuit. [Doctor reminder]: Use hot water bottle, electric heating treasure heating time should not be too long, should leave the body when sleeping. When using, use a towel or a cloth bag to wrap it. Do not apply it directly to the skin. It is better not to use it for people with hemiplegia, diabetes and infants. The safety of electric blanket blankets depends on what kind of heating wire is used. When purchasing, you can touch it with your hand heating line, qualified product of the heating line is relatively thick, diameter of 2.4 mm or more, feel the hardness to be harder, substandard products, the heating line is relatively soft, diameter Less than 1.5mm, feels like root toothpick. The joints of the qualified electric blanket are firm and can withstand repeated dragging. The unqualified electric blanket joints are shredded, and they can be opened at a glance. This electric blanket can easily cause the joint to catch fire and cause a fire. In addition, it is easy to cause electric shock when wet. When using, pay attention to the following matters: 1. Before using the electric blanket, read the instruction manual in detail and operate according to the instructions strictly; the voltage and frequency of the power used must be the same as the rated voltage and frequency on the electric blanket; 2. When in use , We must always check whether the electric blankets are piled up and pleated. If so, flatten the folds before using them. 3. When using a warm-up electric blanket, it is absolutely forbidden to use all night electricity. Before going to bed, To turn off the power; 4, baby and life can not take care of themselves, do not use electric blankets alone, to be accompanied by people; 5, do not place a sharp object on the electric blanket, not to put the electric blanket on the protruding metal or other sharp hard objects Used on. [Experts reminded]: Although electric blankets can keep warm, but the use of time should not be too long, generally 1 hour before bedtime heating, before going to sleep off the power as well, and can not be in direct contact with the human body. People who regularly use electric blankets should increase drinking water in the morning and evening. In addition, pregnant women, infants and young children are best not to use; and people with hypertension, coronary heart disease and other cardiovascular and cerebrovascular diseases and allergies, mouth ulcers, pharyngitis and other patients should not be used. Electric heaters There are many types of electric heaters for home use. Please select an appropriate model according to your application. The local hothouse can be of the reflective type, and all conservatories can use the convection type. Natural convection is used to warm every corner of the room. In addition, the fan type uses a fan motor to convection warm air. In addition to this, there are household heaters powered by kerosene. However, special attention should be paid to safety when using the stove. It is an infant who is at home and avoids accidental burns. 1. Oil-filled electric heaters must be placed straight out of production and cannot be placed in reverse. Because the oil-filled electric heater heats the heat-conducting oil around the heat through a heat-generating tube at the lower end, the heat-conducting oil flows in the pipe to transfer heat. If you put it upside down, lay it flat, or put it diagonally, it will burn the heat pipe. 2, the heater is a constant temperature heating body, because of its high surface temperature, so the surface of the heater can not cover any items, otherwise it will cause the heat of the heater can not be distributed in time and cause burning. When using a special drying rack to dry wet clothes, be sure to wring out the water to avoid the risk of water drops in the heater's control box (except for water-proof). 3, the use of electric heater must use the technical indicators meet the standard three-hole socket with ground. Never use a two-prong outlet without a ground wire because it is prone to static electricity. Sometimes it feels like a hand and it is more dangerous. In addition, the socket should not be located directly above the heater and prevent the heat from rising and burning the power supply. Third, if there are electric appliances that easily cause sudden changes in current and are frequent, such as electric welders, impact drills, etc., which are used together with electric heaters, it is relatively easy to damage the electric heaters. Attention should be paid. It is better to use overcurrents. The protective device's power strip or optional power supply. [Experts reminded]: The use of electric heaters in winter can make the room warm. In order to maintain the indoor temperature suitable for human body temperature, the average passenger should be 17 to 19°C, the child's room is 18 to 20°C, and the bedroom is 14 to 16°C. At present, most electric heaters have a constant temperature control at a fixed time. When the warm room reaches a proper temperature, it will stop heating, which can reduce unnecessary waste of electric energy.

Steel Bolt
Bolt is a kind of fastener which consists of head and screw (cylindrical body with external thread) . It should be used with nut for fastening two parts with through hole, an Anchorage Assembly that anchors the connector to a hardened concrete substrate.
Because the bolt is also a kind of railway accessories, railway accessories is a part of the railway line, here refers to the track including steel rails, sleepers, connecting parts, bed, anti-climbing equipment, rail support and turnout, etc. . As a whole engineering structure, the track laid on the roadbed plays a guiding role in train operation and bears the huge pressure of the locomotive and its load directly. Under the dynamic action of the train, its components must have enough strength and stability to ensure the train to run safely, smoothly and continuously in accordance with the prescribed maximum speed. Main classifications are general and hinged according to the manner in which the joints are loaded. The ordinary main load bearing axial force, but also can bear the lateral load demand is not high. Bolts for reaming holes shall be fitted to the hole dimensions and shall be used when subjected to lateral forces. According to the shape of the head is divided into hexagon head, round head, square head, heavy head and so on. The hexagonal head is the most commonly used. The countersunk head is usually used where a smooth, raised surface is required after joining, because the countersunk head can be screwed into the part. The round head can also be screwed into the part. The tightening force of the square head can be greater, but the size is very large. In addition, in order to meet the needs of locking after installation, there are holes in the head, rod hole, these holes can make the bolt vibration not loose. Some bolts do not thread bare rod to do fine, called fine waist bolt. This bolt is advantageous to the connection subjected to variable forces. There are special high-strength bolts on the steel structure, the head will be bigger and the size will change. Also has the special use: T-slot Bolt, the machine tool fixture with the most, special shape, the head of both sides to be cut off. Anchor Bolts, used for machine and ground connection and fixation, come in a variety of shapes. U-BOLTS, as described above. Wait a minute. There are special welding stud, one end has a thread, one end is not, can be welded on the parts, the other side directly screw nut. The U-BOLT is a non-standard part. It is also called U-bolt because of its u-shaped shape. The two ends of the bolt can be combined with a nut. It is mainly used to fix the leaf spring of a tubular object such as a water pipe or a piece of material such as a car, it is called a riding bolt because it fastens the object in the same way that a man rides a horse.
