DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0029] Example 1:

[0030] This embodiment provides an anti-loosening motor hub cover, comprising:

[0031] The hub cover body 1 has an axial hole 2 for mounting the motor bearing. A shaft cylinder 3 is fixedly provided on the inner wall of the axial hole 2. A plurality of mounting holes 4 are equidistantly opened on the circumference of the hub cover body 1.

[0033] It can be seen from this embodiment that the hub cover body 1 has an axial hole 2 for mounting the motor bearing, and a shaft cylinder 3 is fixedly provided on the inner wall of the axial hole 2. A number of mounting holes 4 are equidistantly provided on the circumference of the hub cover body 1. The hub cover body 1 is fixedly connected to the motor body by bolts passing through the mounting holes 4. A clamping assembly is provided on the side wall of the hub cover body 1, and the bolts are tightened by the clamping assembly to prevent them from loosening, thereby achieving an anti-loosening effect.

[0034] Example 2:

[0035] This embodiment provides an anti-loosening motor hub cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0036] The clamping assembly includes:

[0037] Slide grooves 5: A plurality of slide grooves 5 are equidistantly formed on the side wall of the hub cover body 1;

[0038] Slider 6, a slider 6 is slidably connected in the chute 5;

[0039] The hub cover body 1 is provided with a mounting groove 7 which is in communication with the slide groove 5;

[0040] The limiting block 8 is slidably connected in the mounting groove 7, and the end of the limiting block 8 close to the slide groove 5 is fixedly connected to the slider 6;

[0041] Spring 9 : A spring 9 is provided in the mounting groove 7 , and one end of the spring 9 is fixedly connected to the limit block 8 , and the other end is fixedly connected to the inner wall of the mounting groove 7 .

[0042] It can be seen from this embodiment that when the hub cover body 1 is installed, the slider 6 is first squeezed into the installation groove 7, and then the bolt is installed. When the bolt is installed, the slider 6 is released. The slider 6 moves to the side of the top of the bolt under the complex force of the spring 9 to limit the bolt to prevent the motor from vibrating during use and causing the bolt to loosen and fall off. A limit block 8 is set to limit the slider 6 to prevent the slider 6 from falling off from the slide groove 5.
