The sealing tool for the airtight test of the explosion-proof valve of the battery pack can be installed on the battery pack shell, other explosion-proof valves are sealed, one is reserved for detection, so that the sealing performance of each explosion-proof valve is detected one by one, and the safety of the battery pack during use is guaranteed.
Description
Technical Field
The utility model relates to the technical field of detection of battery packs of new energy automobiles, in particular to a sealing tool for an airtight test of 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 Invention
Aiming at the defects in the prior art, the utility model provides the sealing tool for the airtight test of the battery pack explosion-proof valve, which can seal the explosion-proof valve, thereby facilitating detection.
The utility model is realized by the following technical scheme:
the utility model provides a battery package explosion-proof valve airtight test shutoff instrument, includes fixed cover, snap clamp and sealing seat, fixed cover one side has been seted up and has been run through its wall thickness's location breach, sealing seat sliding connection is in fixed cover inner chamber, the snap clamp rotates the one end of connecting outside the fixed cover, and fixed cover passes through the connecting rod to be connected with the sealing seat, rotates the snap clamp and can drive the sealing seat and slide along fixed cover inner chamber.
In order to facilitate positioning, the outer wall of one end of the fixing sleeve far away from the quick clamp is provided with a groove along the circumferential direction of the fixing sleeve.
In order to further ensure the tightness, a sealing gasket is attached to the end face of one side, far away from the connecting rod, of the sealing seat.
In order to facilitate installation, the sealing seat is fixed with the connecting rod through a screw.
In order to facilitate the rotation of the quick clamp, a nut is fixed on the outer side of the fixing sleeve, and the quick clamp is rotationally connected with the nut through a rotating seat.
The beneficial effects of the utility model are as follows: the sealing tool for the airtight test of the explosion-proof valve of the battery pack can be installed on the battery pack shell, other explosion-proof valves are sealed, one is reserved for detection, so that the sealing performance of each explosion-proof valve is detected one by one, and the safety of the battery pack during use is guaranteed.
Drawings
Fig. 1 is a schematic perspective view of a sealing tool for testing the air tightness of a battery pack explosion-proof valve.
Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the attached drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.

Accordingly, directional terminology is used to describe and understand the utility model and is not limiting of the utility model.
The utility model provides a battery package explosion-proof valve airtight test shutoff instrument as shown in fig. 1, includes fixed cover 1, snap clamp 3 and sealing seat 2, fixed cover 1 is cylindric structure, and fixed cover 1's one side has been seted up and has been run through its wall thickness location breach 8, and location breach 8 downwardly extending runs through fixed cover 1 bottom, simultaneously, fixed cover 1 bottom outer wall has been seted up flutedly 10 along its circumference, sealing seat 2 is cylindric structure, sliding connection in fixed cover 1 inner chamber, and sealing seat 2 bottom face laminating has sealing pad 9, sealing pad 9 and fixed cover 1 inner wall interference fit, fixed cover 1 top central point puts and is fixed with nut 6, snap clamp 3 rotates with nut 6 through rotating seat 4 and is connected, simultaneously, and snap clamp 3 one end rotates and is connected with connecting rod 5, and the connecting rod 5 bottom is fixed mutually with sealing seat 2 top face through screw 7.
When the plugging tool is used, the plugging tool is installed on a shell of a battery pack, the fixing sleeve 1 is rotated, the positioning notch 8 of the fixing sleeve 1 is clamped with a clamping block in a hole of the battery pack, the fixing sleeve 1 is relatively fixed with the battery pack shell and cannot be separated outwards, at the moment, the quick clamp 3 is pressed, the quick clamp 3 drives the sealing seat 2 to move inwards, the sealing seat 2 plugs an explosion-proof valve, the explosion-proof valve cannot be depressurized, other explosion-proof valves are plugged according to the steps, one is left for detection, and therefore the sealing performance detection of each explosion-proof valve is completed one by one.
It should be noted that, the present utility model is not related to the part that is the same as or can be implemented by the prior art.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
