Description

Airtight detection frock of car power battery package

Technical Field

The utility model relates to an electric automobile power battery technical field specifically is an airtight detection frock of automobile power battery package.

Background

The power battery pack of the automobile needs to carry out air tightness detection on the power battery pack, the explosion-proof valve is arranged on the battery pack, the explosion-proof valve plays a role in ventilation and can influence air tightness detection, so that a tool, namely a tool, is needed to plug the explosion-proof valve to prevent air leakage when the detection is carried out, and the explosion-proof valve is replaced after the detection is finished.

The problem of troublesome installation is solved through magnet absorption to current battery package airtight detection frock like the patent of application number CN202122785503.2, but when airtight detection, under the pressure of air, the condition that the adsorption affinity of magnet appears inadequately easily, leads to gas leakage, and if the battery package is not the material such as iron, can not adsorbed by magnet, then the practical value of its frock can significantly discount, and install the frock through the mode of bolt still at present most common one kind, but through the screw-thread hole of bolt spiral department, well-known, this bolt need be screwed very tightly, this phenomenon that just leads to screw-thread hole or bolt to appear drawing and detaining or damage the screw thread very easily.

Further, the difference between the left end of the fixing ring and the left end of the sealing gasket is a distance of half the thickness of the sealing gasket.

Further, the thickness of the fixing ring is not larger than that of the fixing ring.

Furthermore, the clamp pipe is made of high-toughness metal steel.

Further, the maximum diameter of the clamping block must not exceed the maximum diameter of the clamping tube.

Further, the minimum diameter of the clamping block is not larger than the minimum diameter of the clamping tube.

(III) advantageous effects

Compared with the prior art, the utility model provides an airtight frock that detects of car power battery package possesses following beneficial effect:

this airtight frock that detects of car power battery package through fixture block oppression card pipe left part, makes the card pipe card of left part expansion in the screw hole left part, the cooperation of rethread nut to the realization is fixed to this stability that detects the frock, and the installation is very firm, and the gas leakage phenomenon is difficult for appearing, and should detect the frock when fixed, does not use the screw thread on the screw hole, so can not cause the damage to the screw thread in the screw hole.
