[0011] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model. However, the present utility model is not limited to these embodiments.

[0012] As Figure 1 , Figure 2 shown, the novel motor includes a body 1 and a connection end cover 2 formed at the front end of the body 1. The front end of the connection end cover 2 is installed with a front end cover 3 by screws. The middle part of the connection end cover 2 has a shaft platform 4 with a shaft hole. A number of connection rib groups are formed between the shaft platform 4 and the connection end cover 2 and are distributed in a circumferential manner to improve the overall strength of the connection end cover 2. The front end of the connection end cover 2 has a convex platform 5 that protrudes outward and abuts against the front end cover 3. A sealing cavity is formed between the connection end cover 2, the convex platform 5 and the front end cover 3, and a sealing device is installed in this sealing cavity.

[0013] Further elaborating, the sealing device consists of a sealing body 6 and a clamping protrusion 7 formed on the sealing body 6. The connection end cover 2 is provided with an annular clamping groove for the clamping protrusion 7 to be inserted into. The front end of the sealing body 6 protrudes outward to form a sealing cone 8. There is a sealing elastic groove 9 with a V-shaped longitudinal section between the sealing cone 8 and the sealing body 6. Before installing the front end cover 3, the sealing body 6 is installed on the convex platform 5 through the clamping protrusion 7. During the installation of the front end cover 3, the inner wall of the front end cover 3 presses the sealing cone 8, so that the sealing cone 8 closely adheres to the front end cover 3, achieving an efficient sealing effect.

[0014] Further elaborating, the connection rib group consists of an outer rib 10 and an inner rib 11. There is an included angle between the outer rib 10 and the inner rib 11 to improve the overall strength.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0016] Although terms such as body 1, connection end cover 2, front end cover 3, shaft platform 4, convex platform 5, sealing body 6, clamping protrusion 7, sealing cone 8, sealing elastic groove 9, outer rib 10, inner rib 11, etc. are used more in this article, the possibility of using other terms is not excluded. Using these terms is only to more conveniently describe and explain the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
