[0002] The core part of new energy vehicles includes the battery pack, and the water cooling system is an important part of the thermal management system in the battery pack. The conventional water cooling system is mainly composed of flanges, nylon tubes, water inlets and outlets, and water cooling plates. The water cooling plate has high requirements for sealing, so helium inspection is required before leaving the factory to ensure the sealing of the water cooling plate.

[0003] When conventional connecting pipes are used on the water cooling plate, each connecting pipe needs to be matched with a corresponding helium detection plug. Conventional helium detection plugs are relatively independent, that is, each connecting pipe needs to correspond to a helium detection plug, and the outer contour of the connecting pipe will be adjusted specifically according to the application environment. Conventional helium detection plugs need to be put on the connecting pipe when used, so they can only be adapted to conventional appearance connecting pipes.

[0004] When the water-cooled plate adopts an external water nozzle structure, the sealing plug needs to be inserted into the socket of the external water nozzle structure. The conventional helium detection plug cannot be adapted to the external water nozzle structure, so it needs to be improved. Summary of the invention

In other embodiments, the locking groove 17 is disposed on the vertical tube 541, so that the locking block 64 cooperates with the locking groove 17 on the vertical tube 541.

[0073] Reference Figure 6 and Figure 7The connecting rod 62 is inserted into the connecting hole 44 , one end of the connecting rod 62 is connected to the driving rod 61 , and the other end of the connecting rod 62 is connected to the locking rod 63 .

[0074] The implementation principle of Example 2 is as follows: first, the driving rod 61 is raised, and the driving rod 61 drives the locking block 64 to disengage from the locking groove 17, and then the vertical tube 541 is driven to rotate, driving the first fixed block 542 and the second fixed block 544, the first fixed block 542 drives the first sliding rod 5431, the first linkage rod 543 and the first clamping strip 52 to move, and the second fixed block 544 drives the second sliding rod 5451, the second linkage rod 545 and the second clamping strip 52 to move, so that the two clamping strips 52 move away from each other, so that the clamping teeth 53 no longer lock the clamping block 51, and the staff can drive the sealing plug 21 to move in the guide hole 15; conversely, the vertical tube 541 is driven to rotate in the opposite direction, so that the clamping teeth 53 lock the clamping block 51, so that the sealing plug 21 no longer moves, and the driving rod 61 is driven to descend, so that the driving rod 61 drives the locking block 64 to reinsert into the locking groove 17, so that the vertical rod 41 cannot rotate.

[0075] Example 3

[0076] Reference Figure 8 and Fig. 9 The difference between this embodiment and embodiment 2 is that the linkage structure 54 includes a vertical tube 541, a vertical rod 41, a first linkage rod 543, a second linkage rod 545, a gear 546, a first rack 547 and a second rack 548.

[0077] Reference Figure 8 and Fig. 9 The vertical tube 541 is fixedly connected to the inner wall of the guide hole 15 along the length direction of the guide seat 1. The vertical rod 41 is rotatably connected to the vertical tube 541. The gear 546 is sleeved outside the vertical rod 41, and the gear 546 is located above the vertical tube 541.

[0078] Reference Figure 8 and Fig. 9 The first linkage rod 543 is fixedly connected to the end face of one clamping strip 52 facing the sealing plug 21, and the first linkage rod 543 is located on the side of the vertical rod 41 facing the sealing plug 21. The second linkage rod 545 is fixedly connected to the end face of another clamping strip 52 facing the sealing plug 21, and the second linkage rod 545 is located on the side of the vertical rod 41 away from the sealing plug 21.

[0079] Reference Figure 8 and Fig. 9 The first rack 547 is fixedly connected to the end of the first linkage rod 543 away from the sealing plug 21, and the first rack 547 is meshed with the gear 546. The second rack 548 is connected to the end of the second linkage rod 545 toward the sealing plug 21, and the second rack 548 is meshed with the gear 546.

[0080] The implementation principle of Example 3 is: drive the vertical tube 541 to rotate, so that the gear 546 rotates synchronously. Since the first rack 547 and the second rack 548 are both engaged with the gear 546, the gear 546 drives the first rack 547 and the second gear 546 to move, so that the two clamping strips 52 move away from each other, so that the clamping tooth 53 no longer locks the clamping block 51, and the staff can drive the sealing plug 21 to move in the guide hole 15; conversely, drive the vertical tube 541 to rotate in the opposite direction, so that the clamping tooth 53 locks the clamping block 51, so that the sealing plug 21 no longer moves.

[0081] Example 4

[0082] Reference Fig.10 and Fig.11 The difference between this embodiment and embodiment 2 is that the linkage structure 54 also includes a gear 546, a first rack 547 and a second rack 548.

[0083] Reference Fig.10 and Fig.11 The gear 546 is sleeved on the outside of the vertical rod 41, and the gear 546 is located between the vertical tube 541 and the first fixed block 542. The first rack 547 and the first linkage rod 543 are facing one end of the sealing plug 21, and the first rack 547 is meshed with the gear 546. The second rack 548 and the second linkage rod 545 are facing one end of the sealing plug 21, and the second rack 548 is meshed with the gear 546.

[0084] The implementation principle of Example 4 is: driving the vertical tube 541 to rotate can also drive the gear 546 to rotate. Since the first rack 547 and the second rack 548 are both engaged with the gear 546, the gear 546 drives the first rack 547 and the second gear 546 to move, so that the two clamping strips 52 move away from each other, so that the clamping tooth 53 no longer locks the clamping block 51, and the staff can drive the sealing plug 21 to move in the guide hole 15; conversely, driving the vertical tube 541 to rotate in the opposite direction can lock the clamping tooth 53 to the clamping block 51, so that the sealing plug 21 no longer moves.
