Description

Technical Field

[0001] The utility model relates to the field of lifting doors, and particularly to an automatic lifting door. Background Art

[0002] At present, the Chinese utility model with the publication number CN210598758U discloses a flexible automatic lifting door, which includes a frame, a door body, a reduction motor and a transmission mechanism. The door body includes a first curtain cloth, a second curtain cloth and a third curtain cloth. The top of the first curtain cloth is fixedly connected to a top rod, and the bottom is fixedly connected to a first guiding cloth rod. The top of the second curtain cloth is fixedly connected to the first guiding cloth rod, and the bottom is fixedly connected to a second guiding cloth rod. The top of the third curtain cloth is fixedly connected to the second guiding cloth rod, and the bottom is fixedly connected to a third guiding cloth rod. The transmission mechanism is arranged in the frame. Both ends of the three guiding cloth rods are driven by the left and right transmission devices respectively, and the force on both ends is uniform. The guiding cloth rods move up and down stably. At the same time, both ends of the three guiding cloth rods are fixed on the screw rod, replacing the traditional suspended placement, avoiding the sudden drop of the guiding cloth rod caused by machine failure, and being safe and reliable.

[0003] For the existing lifting doors, it is not convenient to replace the door panels. During the use of the lifting door, if it is impacted by the outside world, it will be damaged and needs to be replaced. Generally, the door panel and the winding shaft are fixedly installed through multiple bolts. During replacement, tools are needed for disassembly and assembly. The disassembly and assembly process is relatively cumbersome, increasing the workload, reducing the replacement efficiency, and not having a fire alarm function. Generally, lifting doors are mostly used in warehouses. During the use of the warehouse, fires are likely to occur. If not discovered in time, it will further increase the loss, affect personal safety, reduce the practicability, and when closing the door, if there are people or foreign objects below, it cannot be discovered in time, there are potential safety hazards, and it is easy to be hit and damage the door body. To solve the above problems, we propose an automatic lifting door. Summary of the Utility Model
