Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to an anti-pinch structure for elevator doors. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line.

[0003] At present, the Chinese utility model with the announcement number CN220098236U discloses an elevator door anti-pinch structure for elevators, including a fixed seat, an installation cavity is provided inside the fixed seat, and a dual-axis motor is installed inside the installation cavity. The dual-axis motor drives the screw rod to rotate. With the cooperation of the limit block, the rotation of the screw rod drives the threaded movable rod to move horizontally, driving the clamping piece to move. The two clamping pieces are respectively connected to the closed ends of the two elevator doors, and the overall length of the device can be adjusted according to different elevator doors, which is convenient for use in different environments.

[0004] However, the existing elevator door anti-pinch structure cannot effectively facilitate its rapid assembly and folding, and cannot effectively facilitate its length adjustment support. In order to solve the above problems, we provide an elevator door anti-pinch structure for elevators. Utility Model Content

[0005] The purpose of the utility model is to provide an elevator door anti-pinch structure for an elevator, so as to solve the problems raised by the above background technology.

[0007] Using the above technical solution: the user can pull the sleeve, causing the sleeve to drive the second rotating shaft to slide inside the connecting plate. The insertion rod is then inserted into the socket, which effectively facilitates the rapid splicing of the device, thereby effectively facilitating the rapid assembly and folding of the device. The user can pull the adjustment rod to slide inside the sleeve, and then insert the pin into the sleeve and the adjustment hole, effectively adjusting the length of the device. Then, by turning the handle, the threaded tube rotates on the surface of the threaded rod, facilitating fine-tuning of the length, thereby effectively facilitating the length adjustment support of the device.

[0008] The utility model is further configured such that a threaded rod is bolted to the bottom of the adjusting rod, and a threaded pipe is threadedly connected to the surface of the threaded rod.

[0009] The above technical solution is adopted: by providing a threaded rod, it can be effectively used in conjunction with the threaded pipe.

[0010] The present invention is further configured such that a bearing is sleeved on the bottom of the threaded tube, and a support plate is bolted to the bottom of the bearing and the support rod.

[0011] By adopting the above technical solution, the elevator door can be effectively supported by providing a support plate.

[0012] The present invention is further configured such that a non-slip pad is provided at the bottom of the support plate, and the top of the non-slip pad is bolted to the support plate.

[0013] The above technical solution is adopted: by arranging the anti-skid pad, an effective anti-skid effect can be achieved.

[0014] The present invention is further configured such that one side of the support rod is bolted with a buckle, and one side of the buckle is buckled with the adjusting rod.

[0015] By adopting the above technical solution, the adjusting rod can be effectively limited by providing a buckle.

[0016] The present invention is further configured such that handles are bolted to the front and back of the threaded tube.

[0017] By adopting the above technical solution, the threaded pipe can be easily rotated by providing a handle.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The user can pull the sleeve to make the sleeve drive the rotating shaft 2 to slide inside the connecting plate. Then insert the plug rod into the inside of the socket, which can effectively facilitate the rapid splicing of the device, thereby facilitating the rapid assembly and folding of the device;

[0020] 2. The user can pull the adjusting rod to slide inside the sleeve, then insert the bolt into the sleeve and the adjusting hole, and can effectively adjust the length of the device. Subsequently, by rotating the handle, the threaded tube is rotated on the surface of the threaded rod, which is convenient for fine-tuning the length, so as to effectively facilitate the length adjustment and support of the device.
