Description

Air-tight test inflation tool for explosion-proof valve of battery pack Technical Field The utility model relates to the technical field of detection of battery packs of new energy automobiles, in particular to an air-tightness testing and inflating tool for an explosion-proof valve of a battery pack. Background When the battery of the new energy automobile is packaged and transported, the battery can be placed in a battery pack so as to ensure the transportation safety. A plurality of explosion-proof valves are arranged on the existing battery pack, and when the internal pressure of the battery pack suddenly increases, the explosion-proof valves are automatically opened, so that automatic pressure relief is realized. However, if the battery pack explosion-proof valve which is not detected is directly used, the hidden danger of sealing failure exists. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides a battery pack explosion-proof valve airtight test inflation tool which can seal and inflate an inner cavity of a battery pack and perform airtight test. The utility model is realized by the following technical scheme: The utility model provides a battery package explosion-proof valve airtight test air tool, includes fixing base, quick clamp and fills the gas holder, the fixing base includes integrated into one piece's extension board, and the extension board both ends are buckled perpendicularly to the homonymy and are formed a pair of locating plate, the quick clamp rotates the one end of connecting outside the extension board, it sets up between two locating plates to fill the gas holder, fills gas holder one end and links to each other with the quick clamp through the connecting rod, rotates the quick clamp and can drive to fill the gas holder and slide, and the one end that fills the gas holder and keep away from the connecting rod has hollow inflation chamber, and it is fixed with the head that fills gas holder outer wall and is linked together with the inflation chamber. In order to suck the valve plate in the explosion-proof valve, the inner cavity of the inflation seat is provided with a magnet. In order to prevent the explosion-proof valve from being damaged by the inflation seat, one end of the positioning plate, which is far away from the support plate, is provided with a baffle which is vertically bent inwards and limits the sliding range of the inflation seat. In order to facilitate disassembly and assembly of the quick clamp, rotation of the quick clamp is facilitated, a nut is fixed on the outer side of the support plate, and the quick clamp is rotationally connected with the nut through a rotating seat. In order to facilitate the disassembly and assembly of the inflatable seat, the inflatable seat is fixed with the connecting rod through a screw. The battery pack explosion-proof valve airtight test inflation tool has the beneficial effects that the battery pack explosion-proof valve airtight test inflation tool can be arranged on a battery pack shell, the explosion-proof valve is plugged and opened, the inner cavity of the battery pack is inflated, the pressure is maintained, whether the pressure value changes is detected through the pressure gauge, the air tightness of the battery pack is detected, and the safety of the battery pack during transportation is ensured.
