Explosion-proof storage battery power supply device

Abstract

The invention discloses an explosion-proof storage battery power supply device. The device comprises a box cover; a small hole is formed in the inner wall of one side of the box cover; a spring is arranged in the small hole of the box cover; the lower end of the spring is connected with a rack; the rack is meshed with a gear; the gear is connected to a gear shaft in a sleeving mode; one end, awayfrom the gear, of the gear shaft is sleeved with a driving bevel gear; the driving bevel gear is meshed with a driven bevel gear; the driven bevel gear is connected to a lead screw in a sleeving mode;the driven bevel gear is located at the upper end of the lead screw; a pressing head sleeves the lower end of the lead screw; the lower end of the pressing head is connected with a middle dustproof cover; the two sides of the pressing head are connected with first connecting rods; one ends, away from the pressing head, of the first connecting rods are connected with upper sliding blocks; the upper sliding blocks are connected with second connecting rods; one ends, far away from the upper sliding blocks, of the second connecting rods are connected with lower sliding blocks; and the lower endsof the lower sliding blocks are connected with side dustproof covers. The dustproof cover is added to a joint of an explosion-proof battery in the power supply device, so that dust at the joint of theexplosion-proof battery can be prevented from being accumulated; and moreover, the dustproof cover can automatically cover on the joint of the explosion-proof battery, so that the use is convenient.

Description

technical field [0001] The invention relates to the technical field of power supply devices, in particular to an explosion-proof storage battery power supply device. Background technique [0002] Explosion-proof battery is a new type of battery product. It is made of high-safety materials and can effectively contain the battery explosion. The safety characteristics of explosion-proof batteries are its biggest feature. Using an explosion-proof battery as a power supply has a high safety factor, but when the explosion-proof battery is placed in the power supply unit, the connection pool of the explosion-proof battery is exposed to the air, because the connection is conductive, the dust in the air is easy to absorb on it, and the power supply is prone to heat. It is easy to cause dust and fire, which is extremely unfavorable to the safety of the power supply unit. Contents of the invention [0003] The object of the present invention is to propose an explosion-proof storage ...
