[0023] In view of the deficiencies in the prior art, the present inventor has long-term research and a large number of practices, and finally proposes the technical scheme of the utility model. The technical scheme, its implementation process and principles will be further explained as follows.

[0024] As shown in Figure 1 The utility model discloses a check mechanism, this check mechanism, including installation baseplate 1, elastic part and buckle 5, be provided with motor placing table 3 on installation baseplate 1, be provided with mounting hole 4 on motor placing table 3, in the process of installation, first, the bearing of motor output end is aligned mounting hole 4, makes the bearing of motor output end into mounting hole 4 and realizes motor center positioning.

[0025] The elastic part is arranged at one side of the motor placing table 3, the motor 100 can pass through when the elastic part is in the compressed state, and the motor 100 can be blocked when the elastic part is in the relaxed state to prevent the motor 100 from rotating, the elastic part can include a spring or a spring piece 2, and in the embodiment, the elastic part includes the spring piece 2, as shown in Figure 2 、 Figure 3 The corresponding position of the spring piece 2 on the installation baseplate 1 is provided with a through hole 6, one end of the spring piece 2 away from the motor placing table 3 is fixedly connected with the installation baseplate 1, and the other end of the spring piece 2 close to the motor placing table 3 is a free end, the upper end surface of the spring piece 2 is higher than the upper end surface of the motor placing table 3 when the spring piece 2 is in the relaxed state, so that the motor 100 can be blocked to prevent the motor 100 from rotating. When installing, the mounting plate 101 on the motor 100 presses the spring piece 2, so that the spring piece 2 is in the pressed state, at this time, the upper end surface of the spring piece 2 is lower than the motor mounting plate 101, then the motor is rotated to rotate the motor mounting plate 101, at this time, the spring piece 2 is separated from the pressing of the motor mounting plate 101 and is in the relaxed state and is bounced up, the upper end surface of the bounced-up spring piece 2 is higher than the motor mounting plate 101, so that the motor mounting plate 101 is clamped, and the motor mounting plate 101 can be prevented from rotating.

[0026] As shown in Figure 4 、 Figure 5As shown, the buckle 5 is arranged on one side of the mounting base 1, and the buckle 5 is used at least for limiting the motor to prevent the motor from moving axially. Specifically, the buckle 5 is arranged in an L shape, and the buckle 5 comprises a longitudinal plate 7 and a transverse plate 8. One end of the longitudinal plate 7 is fixedly connected with the mounting base 1, and the other end of the longitudinal plate 7 is fixedly connected with the transverse plate 8. The transverse plate 8 is arranged on the side of the motor placing table 3 away from the mounting base 1, and the transverse plate 8 is used at least for preventing the motor from moving axially. During installation, the mounting plate 101 on the motor presses the elastic sheet 2, so that the elastic sheet 2 is in a pressed state. The elastic sheet 2 is lifted up when the pressing of the elastic sheet 2 by the mounting plate 101 on the motor is released, so that the rotation of the motor can be limited. At this time, the mounting plate 101 of the motor is arranged in the groove of the buckle 5, so that the axial movement of the mounting plate 101 of the motor, i.e., the up-and-down movement of the motor in the drawing, can be limited (for example, the motor cannot move up and down in the drawing). Figure 6 The rotation mentioned herein refers to the rotation of the whole motor.

[0027] The motor is limited in rotation by the elastic component, and the motor is limited in up-and-down movement by the buckle 5. Compared with the traditional method of locking and fixing the motor by using multiple screws, the motor fixing time is reduced, the labor is saved, the labor cost is reduced, the production efficiency is improved, and the safety factor is improved.

[0028] Preferably, in order to enable the mounting plate 101 of the motor to smoothly enter the groove of the buckle 5, the end of the transverse plate 8 close to the side of the motor placing table 3 is arranged as a guide slope 9, and the guide slope 9 can guide the mounting plate 101 of the motor to enter the groove of the buckle 5.

[0029] In some embodiments, in order to increase the strength of the buckle 5, a reinforcing rib 10 is arranged on the side of the longitudinal plate 7 away from the motor placing table 3. The reinforcing rib 10 can increase the strength of the buckle 5, so that the buckle 5 cannot be tilted or even broken during the process of limiting the movement of the mounting plate 101 of the motor.

[0030] In some embodiments, the elastic component and the buckle 5 are both arranged in two groups, and the two groups of elastic components are symmetrically arranged with respect to the center of the mounting hole 4. The two groups of buckles 5 are symmetrically arranged with respect to the center of the mounting hole 4, so that the motor can be better limited and the motor can be more firmly installed.

[0031] It should be understood that the above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and the protection scope of the present application cannot be limited thereto. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
