Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a fixing nut for a new energy vehicle battery. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle-mounted power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. The core of new energy vehicles is the battery. The general new energy battery box adopts a rectangular box body, and a battery slot that is compatible with the new energy battery is opened in the box body, and then the battery is placed in the battery slot. The box body and the battery are configured in a single configuration, and heat is dissipated by opening heat dissipation holes on the battery box.

[0003] Existing new energy battery boxes require nuts and other fasteners to fix components such as battery mounting frames, and existing cylindrical nuts, such as the attached Figure 5 When the wrench is used to rotate and tighten the nut, slippage occurs between the wrench and the nut, which is inconvenient to use. Utility Model Content

[0004] The utility model aims to provide a fixing nut for a new energy vehicle battery in order to solve the problem of slippage between a wrench and a nut when the wrench is used to rotate and tighten the nut.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solution: a fixing nut for a new energy vehicle battery, comprising:

[0006] A nut body, wherein a threaded hole is arranged in the nut body, and a plurality of racks are arranged on the side of the nut body;

[0007] At least one cushion block, the cushion block is fixedly connected to the bottom of the nut body;

[0008] A cap is arranged on the top of the nut body, and the cap is coaxially arranged with the nut body.

[0009] As a further description of the above technical solution:

[0010] A cavity is arranged in the cap, the cavity is communicated with the threaded hole, and a gasket is arranged in the cavity.

[0011] As a further description of the above technical solution:

[0012] The cavity is coaxially arranged with the threaded hole.

[0013] As a further description of the above technical solution:

[0014] The cap and the nut body are an integrally formed structure.

[0015] As a further description of the above technical solution:

[0016] A wear-resistant layer is arranged at the bottom of the nut body.

[0017] As a further description of the above technical solution:

[0018] An insulating layer is arranged between the wear-resistant layer and the nut body.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0020] 1. In the utility model, a plurality of racks are arranged on the side of the nut body, so that when in use, the friction between the wrench and the nut body can be increased to avoid slipping between the wrench and the nut, making it easier for users to install and disassemble the nut.

[0021] 2. In the utility model, the cap is provided to improve the sealing between the nut body and the screw, prevent moisture in the air from entering the gap between the nut body and the screw, and avoid rust; at the same time, a gasket is provided inside the cap, and the gasket is an elastic gasket. When the nut body is tightened, the screw presses the elastic gasket, and the elastic gasket can strengthen the connection tightness between the bolt and the screw to prevent loosening.

[0022] 3. In the utility model, by providing the spacer, the nut body can be prevented from directly contacting the installation position during installation, thereby reducing the degree of wear on the nut body and the installation object and increasing their service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-4 The utility model provides a technical solution: a fixing nut for a new energy vehicle battery, which includes:

[0033] A nut body 1, wherein a threaded hole 2 is provided in the nut body 1, and a plurality of racks 3 are provided on the side of the nut body 1;

[0034] At least one cushion block 4, the cushion block 4 is fixedly connected to the bottom of the nut body 1;

[0035] The cap 5 is arranged on the top of the nut body 1 , and the cap 5 is coaxially arranged with the nut body 1 .

[0036] The cap 5 is provided with a cavity 6, which is communicated with the threaded hole 2, and a washer 7 is provided in the cavity 6. When the nut body is tightened, the screw compresses the elastic washer, which can strengthen the connection between the bolt and the screw to prevent loosening.

[0037] The cavity 6 is coaxially arranged with the threaded hole 2. This facilitates assembly between the screw and the nut body.

[0038] The cap 5 and the nut body 1 are integrally formed, which can improve the connection strength of the cap.

[0039] The bottom of the nut body 1 is provided with a wear-resistant layer 8.
