[0005] To achieve the above purpose, the utility model provides a push rod mechanism, which includes a driving motor, a push rod, and a driving wheel assembled on a bracket. The push rod is slidably connected to the bracket, and an elastic member is connected between the push rod and the bracket to keep the push rod from protruding from the bracket. The driving motor is used to drive the driving wheel to rotate. The driving wheel is arranged behind the push rod and has a convex portion for pushing the end of the push rod out of the bracket.
[0006] In one or more embodiments, one or more convex portions are provided on the driving wheel.
[0007] In one or more embodiments, a position sensing switch is arranged on the bracket, and the triggering portion of the position sensing switch is on the path of the convex portion rotating with the driving wheel.
[0008] In one or more embodiments, the elastic member is a compression spring, and both ends of the compression spring are respectively connected to the push rod and the bracket.
[0009] In one or more embodiments, the driving motor is installed outside the bracket by screws, and an avoidance opening for the rotating shaft of the driving motor to pass through is formed on the bracket. The push rod and the driving wheel are arranged inside the bracket.
[0010] In one or more embodiments, the bracket includes a housing and a bottom plate. The housing and the bottom plate are fixedly connected by screws, and mounting holes are provided on the bottom plate.
[0011] The effect of the utility model compared with the background art is that this push rod structure has the advantages of simple overall structure and small volume, and can reliably realize the reciprocating movement of the push rod.

Specific Embodiment
[0015] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with embodiments and drawings. This embodiment is only used to explain the present utility model and does not constitute a limitation on the protection scope of the present utility model.
[0016] Please refer to Figures 1-3 , this application provides a push rod mechanism, which includes a drive motor 2, a push rod 3, and a drive wheel 4 assembled on a bracket 1. The push rod is slidably connected to the bracket. Specifically, a slideway is provided inside the bracket to cooperate with the push rod for sliding, and an elastic member is connected between the push rod 3 and the bracket 1 to keep the push rod from protruding from the bracket. The drive motor 2 is used to drive the drive wheel 4 to rotate. The drive wheel is arranged behind the push rod 3 and has a convex portion 41 for pushing the end 31 of the push rod out of the bracket. Specifically, when the drive motor drives the cam to rotate, when the convex portion rotates to contact the push rod, it starts to push the push head of the push rod outwards. When the convex portion disengages from the push rod, the push head of the push rod retracts back into the bracket under the elastic force of the elastic member.
[0017] One or more convex portions 41 are provided on the drive wheel 3. In this embodiment, two convex portions are provided on the drive wheel, and the number can be specifically selected according to actual needs.
[0018] A position induction switch 5 is provided on the bracket 1. The triggering portion of the position induction switch is on the path of the convex portion 41 rotating with the drive wheel 4. Each time the convex portion triggers the position induction switch, an electrical signal will be sent, so as to know whether the push rod is in the extended state or the retracted state.
[0019] The elastic member is a compression spring. The two ends of the compression spring are respectively connected to the push rod 3 and the bracket 1. The compression spring can pull the push head of the push rod back into the bracket after the convex portion disengages from the push rod.
[0020] The drive motor 2 is installed on the outside of the bracket 1 by screws. An avoidance opening for the rotating shaft of the drive motor is provided on the bracket. After the rotating shaft passes through the avoidance opening, it is axially connected to the drive wheel. The push rod 3 and the drive wheel 4 are arranged inside the bracket to prevent the push rod and the drive wheel from being exposed, playing a protective role.
[0021] The bracket 1 includes a housing 11 and a bottom plate 12. The housing and the bottom plate are connected and fixed by screws. Installation holes 6 are provided on the bottom plate. After the push rod structure is installed and fixed through the installation holes on the bottom plate, it can be used.
[0022] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or variations made by those of ordinary skill in the art according to the disclosure of the present utility model shall be included in the protection scope recorded in the claims.
