[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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.

[0023] Example:

[0024] like Figures 1 to 3 As shown, a stable assembly type end cover for an output shaft of a motor comprises a casing 1, an end cover 2 is arranged on the front side of the casing 1, a plurality of slots 101 are opened around the front side of the casing 1 near the periphery, a first threaded opening 102 is opened on the periphery of the casing 1 near the front side corresponding to the slot 101, a threaded rod 103 is arranged inside the first threaded opening 102, an insert 201 is arranged on the back side of the end cover 2 corresponding to the slot 101, a second threaded opening 202 is opened through the outer side of the insert 201, a circular groove 203 is opened near the center of the end cover 2, slide grooves 204 are symmetrically opened on the front side of the end cover 2 and located on the left and right sides of the circular groove 203, a slider 205 is arranged inside the slide groove 204, a plurality of air permeable grooves 206 are opened equidistantly from top to bottom on the front side of the end cover 2 near the left and right sides, and a stopper 207 is arranged on the back side of the end cover 2 corresponding to the air permeable grooves 206.

[0025] like Figures 1 to 3As shown, the interior of the slot 101 is symmetrically provided with anti-skid pads 104 near the outer side and the inner side, and the anti-skid pads 104 are bonded to the slot 101. The anti-skid pads 104 can increase the friction between the insert 201, making the insert 201 more firm and improving the stability of use. The threaded rod 103 is adapted to the first threaded opening 102 and the second threaded opening 202. Through the adaptation of the threaded rod 103 to the first threaded opening 102 and the second threaded opening 202, the threaded rod 103 can be rotated into the interior of the first threaded opening 102 and the second threaded opening 202, thereby completing the connection between the end cover 2 and the housing 1, and the insert 201 is fixedly connected to the end cover 2, and the insert 201 is adapted to the slot 101. Through the fixed connection of the insert 201 and the end cover 2, the insert 201 can be made more firm to prevent it from falling off during use. , improve the stability of use, the slider 205 is slidably connected to the slide groove 204, and the stopper 207 is fixedly connected to the slider 205. Through the fixed connection between the slider 205 and the stopper 207, the stopper 207 can be driven to slide up and down, so as to open or close the ventilation groove 206, thereby improving the convenience of use. A dustproof net 208 is arranged inside the ventilation groove 206, and the dustproof net 208 is fixedly connected to the ventilation groove 206. Through the fixed connection between the dustproof net 208 and the ventilation groove 206, dust in the airflow can be blocked to prevent it from entering the interior of the casing 1, thereby improving the protection effect. A mountain-shaped ventilation groove is provided on the front side of the stopper 207 corresponding to the ventilation groove 206. Through the mountain-shaped ventilation groove provided on the front side of the stopper 207, it can be avoided that the stopper 207 blocks the ventilation groove 206 when it is opened, thereby improving the heat dissipation effect.

[0026] To sum up, when installing and using a stable assembly type end cover for the motor output shaft, first insert the insert 201 on the back of the end cover 2 into the slot 101. Under the action of the anti-slip pad 104, the insert 201 and the slot 101 can be made tighter. Turn the threaded rod 103 to spiral into the first threaded opening 102 and pass through the second threaded opening 202 to complete the fixation of the end cover 2 and the casing 1, effectively reducing the probability of loosening. Before use, push the slider 205 to drive the block 207 to slide up or down, so that the block 207 is staggered with the air groove 206, thereby opening the air groove 206, thereby improving the heat dissipation effect and preventing the service life from being reduced due to excessive temperature.
