Embodiment Construction
[0014] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0015] A certain amount of gas will be generated during the charging and discharging process of the car battery, and the pressure inside the battery will also increase as the amount of gas generated increases. When the pressure increases to a certain level, the battery will deform, and in severe cases, it will explode and cause a fire. To solve this problem, an explosion-proof valve is added to the battery.
[0016] see figure 1 , a kind of automobile battery explosion-proof valve of the present invention is made up of nut 1, pressure cap 2, shield 3, plug 4, sealing ring 5, sealing ring 6, backing plate 7, upper cover 8, copper wire 9, so The sealing ring 6 is used to seal between the pressure cap 2 and the upper cover 8, the pressure cap 2 passes through the upper cover 8, the backing plate 7, and the sealing ring 6 in turn, and is...

The present invention relates to a vehicle battery explosion-proof apparatus. The present invention discloses a vehicle battery explosion-proof valve, which comprises a screw cap 1, a pressing cap 2, a protection cover 3, a plug 4, a sealing ring 5, a sealing ring 6, a pad plate 7, an upper cover 8, and a copper wire 9, wherein a position between the pressing cap 2 and the upper cover 8 is sealed by using the sealing ring 6, the pressing cap 2 sequentially passes through the upper cover 8, the pad plate 7 and the sealing ring 6, and forms a threaded connection on the bottom of the pressing cap 2 through the screw cap 1, the sealing ring 5 is sleeved on the plug 4, the plug 4 is pressed into a hole on the top of the pressing cap 2, the plug 4 and the pressing cap 2 are connected through the cooper wire 9, a plurality of bending wire sections are formed after the cooper wire 9 is tightly tied, and the protection cover 3 is sleeved outside the pressing cap, and is connected with the pressing cap through threads. The vehicle battery explosion-proof valve has characteristics of safety, reliability, repeated use, simple installation and convenient use.
Description
technical field [0001] The invention relates to an explosion-proof device for an automobile battery, in particular to an explosion-proof valve for an automobile battery. Background technique [0002] At present, the battery explosion-proof valve usually produced in China is bonded with a layer of metal film or plastic film on the explosion-proof joint of the battery. When the gas is generated in the battery, the pressure is too high to burst the metal film or plastic film to achieve the purpose of pressure relief and explosion protection. . This explosion-proof valve is difficult to install, prone to failure, short life, poor production performance, and can only be used once. Contents of the invention [0003] The object of the present invention is to provide a safe, reliable, reusable, simple to install and convenient to use automobile battery explosion-proof valve. [0004] In order to achieve the above object, the present invention has the following technical solution...
