Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof doors, in particular to an explosion-proof door with a driving structure. Background Art

[0002] In order to prevent accidents, the existing cold storage generally uses explosion-proof doors when selecting doors. However, traditional explosion-proof doors are very heavy. When using them, the staff need to work hard to open or close them, which increases the labor intensity of the staff and wastes time. Therefore, we propose an explosion-proof door with a drive structure to solve the above problems.

[0003] The patent document with the published announcement number CN213418899U discloses an explosion-proof door with a driving structure, including a door frame, wherein the positions of the left and right sides of the inner top of the door frame are respectively fixedly connected to an arc-shaped slide groove, the inner sliding connection of the arc-shaped slide groove is connected to a slider, the bottom surface of the slider is fixedly connected to a vertical rod, the bottom surface of the vertical rod is fixedly connected to the explosion-proof door body, the explosion-proof door body is connected to the side of the door frame by a heavy hinge, one side of the vertical rod is connected to a support rod by a rotating shaft, and the other end of the support rod is connected to a connecting rod by a rotating shaft. The device can facilitate the opening of the explosion-proof door, saving time and effort. By setting an arc-shaped slide groove at the inner top of the door frame, the slide groove can be conveniently moved in an arc shape. By setting a vertical rod on the bottom surface of the slider and a rotatable support rod on one side of the vertical rod, the slider can be easily pushed to slide. By setting an electric telescopic rod, the explosion-proof door can be conveniently driven and opened and closed.

[0004] The above devices are relatively simple in fixing the explosion-proof door body and the door frame, and only use an explosion-proof key lock for safety protection. Therefore, an explosion-proof door with a driving structure is needed. Utility Model Content
