Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

the utility model provides a motor with anti structure that falls, including motor 1, the 1 outside of motor is equipped with protection casing 2, and motor 1's center pin runs through

protection casing

2, 2 inboard fixedly connected with buffer spring 3 of protection casing, buffer spring 3's other end fixedly connected with inner ring 4, and inner ring 4 runs through protection casing 2,

inner ring

4 and 2 sliding connection of protection casing, inner ring 4 is close to the one end fixedly connected with packing ring 5 at motor 1 center, motor 1's the center pin outside fixedly connected with swivel nut 7, swivel nut 7 outside screwed connection has position sleeve 8, and motor 1's center pin runs through position sleeve 8.

The protective cover 2 is provided with 2 protective covers, the protective covers 2 are symmetrically arranged at the left side and the right side of the motor 1, the protective effect of the motor 1 is better due to the arrangement, the gasket 5 is in sliding connection with the motor 1, the gasket 5 is made of a rubber plate, when the motor collides, the phenomenon that the shell of the motor 1 is crushed by the inner ring 4 is avoided to the greatest extent, the inner side of the threaded sleeve 7 is in sliding connection with the limiting block 6, the limiting block 6 penetrates through the threaded sleeve 7, the limiting block 6 is fixedly connected with the protective cover 2, the limiting block 6 is in sliding connection with the central shaft of the motor 1, the number of the limiting blocks 6 is 4, the limiting block 6 is symmetrically fixed on the protective cover 2, the limiting effect is achieved on the protective cover 2 due to the arrangement, the stability after the protective cover 2 is installed is ensured, the limiting ring 9 is arranged at one end, far away from the center of the motor 1, of the inner side of the positioning sleeve 8, and the limiting ring 9 is in sliding connection with the central shaft of the motor 1, spacing ring 9 and position sleeve 8 fixed connection, this kind of setting has played spacing effect to position sleeve 8 to be convenient for install position sleeve 8 fast.
