[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is divided into electric motors (symbol: M) and generators (symbol: G). When fixing the rear cover of the motor, a motor cover fixing structure is required.

[0003] Traditional motor cover fixing structures are mostly fixed by bolts, and it is very troublesome to fix multiple sets of bolts one by one, which directly leads to the fixing process of the entire fixing structure being too cumbersome, and certain tools need to be carried to complete the entire fixing process. If the tools are lost or not carried, they need to be found separately, which greatly reduces work efficiency. Utility Model Content

[0004] The utility model aims to solve the shortcoming of the prior art that the fixing process is too complicated, and proposes a motor cover fixing structure.

[0007] Preferably, the fixing assembly includes multiple groups of fixing blocks uniformly fixedly connected to the limit sleeve, the front side of each group of fixing blocks is fixedly connected to an extension column, the back side of the motor body is uniformly fixedly connected to multiple groups of fixing plates, the fixing plate is provided with an auxiliary groove for use with the extension column, one side of the extension column is fixedly connected to a clamping plate and an end of the clamping plate away from the extension column is inserted into the fixing plate, the side of the fixing plate away from the motor body is fixedly connected to a bracket, the bracket is provided with a locking frame, one end of the locking frame is fixedly connected to a top plate, the other end of the locking frame passes through the fixing plate and is inserted into the auxiliary groove, a first spring is wound around the locking frame and both ends of the first spring are fixedly connected to a side where the bracket and the top plate are close to each other, and the locking frame and the extension column are in contact with each other.

[0008] Preferably, the fixing assembly also includes a T-shaped fixing rod fixedly connected to one side of the bracket and the fixing plate, and slides are slidably provided on two adjacent groups of the T-shaped fixing rods, and the first pressure plate and the second pressure plate are respectively fixedly connected to the side of the slide close to the bracket and the fixing plate, the end of the first pressure plate away from the slide passes through the bracket and fits on the locking frame, and the end of the second pressure plate away from the slide fits on the clamping plate, and the locking frame is provided with a square groove used in conjunction with the first pressure plate, and a second spring is wound around the T-shaped fixing rod and the two ends of the second spring are respectively fixedly connected to the slide and the discs of the T-shaped fixing rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The motor cover fixing structure is convenient for positioning the motor body and the rear cover by setting a fixing component and utilizing the plugging of the extension column and the auxiliary groove. At this time, by rotating the rear cover, the extension column and the clamping plate can be driven to rotate synchronously until the clamping plate contacts the second pressure plate. As the clamping plate continues to rotate, the second pressure plate, the slide plate and the first pressure plate can be pushed to move outward synchronously, and the second spring can be compressed until the extension column contacts the inner wall of one side of the auxiliary groove. At this time, the first pressure plate will completely disengage from the square groove, releasing the locking state of the locking frame. At this time, the elasticity of the first spring is utilized The rebound will drive the locking frame to move quickly and be inserted into the auxiliary groove, so that the extension column and the clamping plate can be quickly fixed to avoid rotation, and the elastic rebound of the second spring can be used to continuously push the first pressure plate and the second pressure plate to squeeze the locking frame and the clamping plate, so that the locking frame and the extension column can be clamped more tightly to avoid separation, thereby facilitating the quick installation and fixation of the motor body, the limit sleeve and the rear cover. The entire fixing process does not require bolts, and the clamping fixing method is adopted throughout the process. The entire installation process only requires rotation, which is simple and convenient, and improves the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The limitation on the number of fixing blocks 7 and fixing plates 5 can further improve the stability of the motor body 1 and the back cover 2 during installation. , an auxiliary groove 6 for use with the extension column 8 is opened on the fixing plate 5, and a clamping plate 9 is fixedly connected to one side of the extension column 8, and the end of the clamping plate 9 away from the extension column 8 is inserted on the fixing plate 5, and the auxiliary groove 6 and the clamping plate 9 are both arc-shaped structures. By providing the auxiliary groove 6 and the clamping plate 9 with an arc-shaped structure, it is more convenient to plug in and avoid obstruction. A bracket 10 is fixedly connected to the side of the fixing plate 5 away from the motor body 1, and a locking frame 11 is inserted on the bracket 10. One end of the locking frame 11 is fixedly connected to the top plate, and the other end of the locking frame 11 passes through the fixing plate 5 and is inserted in the auxiliary groove 6. The end of the locking frame 11 away from the top plate is a cylindrical structure, and the design of the cylindrical structure at one end makes it more convenient to clamp the locking frame 11, and the locking frame 11 is wrapped around A first spring 13 is wound around it and both ends of the first spring 13 are fixedly connected to the side where the bracket 10 and the top plate are close to each other, and the locking frame 11 and the extension column 8 are close to each other. The fixing assembly also includes a T-shaped fixing rod 15 fixedly connected to one side of the bracket 10 and the fixing plate 5, and a slide plate 16 is slidably provided on two adjacent groups of T-shaped fixing rods 15. The side of the slide plate 16 close to the bracket 10 and the fixing plate 5 is respectively fixedly connected to a first pressing plate 18 and a second pressing plate 19.

Then the user rotates the rear cover 2, thereby driving the extension column 8 and the snap-on plate 9 to rotate synchronously until the snap-on plate 9 contacts the second pressure plate 19. As the snap-on plate 9 continues to rotate, the snap-on plate 9 can push the second pressure plate 19 to move outward, thereby synchronously driving the slide The plate 16 and the first pressure plate 18 move outward and compress the second spring 17. When the extension column 8 contacts the inner wall of one side of the auxiliary groove 6, the first pressure plate 18 will completely break away from the contact with the square groove 14. The elastic rebound of the first spring 13 is used to drive the locking frame 11 to move quickly until it is inserted into the auxiliary groove 6, so that the extension column 8 and the clamping plate 9 can be quickly fixed. At the same time, the elastic rebound of the second spring 17 can make the locking frame 11 and the extension column 8 clamped more tightly to avoid separation, so that the motor body 1 can be quickly installed and fixed with the limit sleeve 3 and the back cover 2. The entire installation process only requires rotation, which is simple and convenient, thereby improving the installation efficiency.
