[0002] In factories, workshops and other places, gates are usually installed to ensure the on-site environment and operation requirements. Limited by the space and cost of the site, the gate is usually installed with common hinges or shafts. Although this installation method is convenient for opening and closing the gate, it is easy to cause frequent back and forth shaking when the gate is opened and the hinges or shafts have errors in the assembly accuracy relative to the door body, causing greater wear on the door body. When the shaking is large, it will affect the on-site environment, damage the load-bearing components of the door installation part or damage other surrounding equipment, and may even cause personal safety accidents.

[0003] Existing door stop fixing devices are usually installed on the wall side of a one-way opening door body to limit the position of the door body when it is opened toward the wall to prevent the door body from hitting the wall. They cannot be used to fix doors in factories, workshops and other places.

[0004] Other door stop devices in the prior art also have magnetic door stop devices embedded in the bottom of the door, which use the magnetic attraction of hidden magnets on the door body to achieve the door stop function without affecting the entry and exit of equipment materials and ventilation. However, this door stop device needs to be embedded during concrete pouring, which is cumbersome to operate and requires extensive modifications to the existing door and the corresponding ground. In addition, this door stop device only limits the door in one direction and cannot prevent the door from shaking back and forth. It is also not suitable for scenarios where the door limit is fixed with problems of shaking back and forth. Utility Model Content
