Description

Tire holder

Technical Field

The utility model relates to a tire holder.

Background

At present more and more parking places adopt AGV to do the short distance transportation in the field or transport the vehicle with AGV, and very important mechanism is vehicle tire fixture among the AGV, makes the vehicle break away from ground through tire fixture, bears the weight of vehicle on the AGV. The patent with publication number CN207553698U discloses a tire clamping arm device and a tire clamping device, which drive the clamping arm to move along the arc-shaped plate through a pulling plate, and the patent with publication number CN210760417U discloses a tire clamping and locking device for a supporting platform, which directly pushes the clamping arm to move along the arc-shaped guide rail through a push rod, but both of the above two structures need to occupy a larger space, the number of rod systems of the mechanism is also large, and the actuating mechanism is large and complex, so that the tire clamping mechanism occupies a large space and has higher cost.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough of above-mentioned technique and provide a part and used less, temporarily use the tire holder that the space is little.

In order to achieve the above object, the embodiment of the present invention adopts the following technical solutions:
