[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1: A leak-proof fastener for a new energy vehicle battery pack, such as... Figures 1-5 As shown, the device includes a screw 1 and a nut 4. The nut 4 is fixedly installed on the top of the screw 1. The nut 4 is provided with a disassembly mechanism. The screw 1 is provided with a lubrication mechanism. The disassembly mechanism includes a disassembly component 3. The disassembly component 3 includes a limiting slide groove 32. The limiting slide groove 32 is opened at the top of the nut 4. A limiting block 31 is slidably provided on the inner wall of the limiting slide groove 32. A rack 33 is fixedly installed on the limiting block 31. A baffle 37 is fixedly installed at one end of the rack 33. A gear 34 is rotatably connected to the top of the nut 4. The gear 34 meshes with the rack 33. A spring 35 is fixedly installed on the gear 34. A pin 36 is fixedly installed at one end of the spring 35. One end of the pin 36 passes through the bottom end of the gear 34.

[0028] The lubrication mechanism includes a lubrication component 2, which includes a first flow groove 24. The first flow groove 24 is formed on the inner wall of the screw 1. A second flow groove 21 is formed on the surface of the screw 1. The second flow groove 21 is connected to the first flow groove 24. An injection hole 22 is formed on the surface of the nut 4. One end of the injection hole 22 is connected to the first flow groove 24. A plug 23 is inserted into the inner wall of the injection hole 22.

[0029] The cross-sectional shape of the limiting groove 32 is convex, and the cross-sectional shape of the limiting block 31 is convex.

[0030] The top of the nut 4 is opened in the slot 38, which is cylindrical in shape, and the inner cavity of the slot 38 is adapted to the bottom of the pin 36.

[0031] When using the device, if it is necessary to disassemble the fastener, a wrench can be used to engage the nut 4 for disassembly. If the wrench cannot directly engage the nut 4 due to size limitations, the pin 36 can be pulled to remove one end of the pin 36 from the slot 38, thereby rotating the gear 34. When the gear 34 rotates, it meshes with the racks 33 on both sides, causing the racks 33 on both sides to move. Under the limiting action of the limiting groove 32 and the limiting block 31, the racks 33 on both sides will move in opposite directions. When the wrench moves, it will cause the two side plates 37 to slide in opposite directions until the two side plates 37 move to the distance required for the wrench to engage. Then, the pin 36 is released, and the pin 36 is inserted into the slot 38 under the action of the spring 35, thereby achieving the purpose of fixing the gear 34, rack 33 and baffle 37. The wrench can then be smoothly engaged on the two side plates 37, and the bolt can be easily disassembled. Through the above settings, the problem of the wrench being non-adjustable is solved, making the bolt disassembly process more flexible and convenient.

[0032] If lubrication is required before disassembling the bolt, the plug 23 can be removed from the inner wall of the injection hole 22. Then, lubricant can be injected into the inner wall of the injection hole 22 using a syringe. The lubricant will enter the first flow groove 24 along the injection hole 22, and then enter the second flow groove 21 from the first flow groove 24. Finally, it flows to the surface of the bolt through the second flow groove 21. The above arrangement facilitates the lubrication of the bolt, thereby making the bolt disassembly easier.

[0033] Example 2: A leak-proof fastener for a new energy vehicle battery pack, such as... Figures 1-5 As shown, the nut 4 has a fixing hole 5, which is a cylindrical through hole.

[0034] Two rivets 6 are inserted into the fixing hole 5.

[0035] The bottom end of the nut 4 is provided with a sliding groove 7, and a sliding block 8 is slidably disposed on the inner wall of the sliding groove 7.

[0036] A sealing ring 9 is fixedly installed at the bottom of the sliding block 8. The sealing ring 9 is circular in shape.

[0037] During use, the sliding block 8 slides smoothly within the sliding groove 7 during bolt installation, ensuring that the sealing ring 9 fits tightly around the connection surface, forming a sealing barrier. Since both the sliding block 8 and the sealing ring 9 are made of fluororubber, a material with extremely high heat resistance, corrosion resistance, oil resistance, and chemical resistance, it is commonly used for sealing applications in high-temperature and highly corrosive environments. It can withstand the high-temperature environment and potential chemical corrosion inside the battery pack, making it very suitable for sealing fasteners in the battery pack. Furthermore, with the fixing hole 5 and rivet 6 provided, when the bolt needs to be locked, the rivet 6 can be passed through the fixing hole 5 and inserted into the mounting surface to lock the bolt, thus helping to maintain the stability of the fastener.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
