Description

Technical Field

[0001] The utility model relates to the technical field of elevator detection, in particular to a car door auxiliary opening mechanism for elevator detection. Background Art

[0002] During the elevator inspection process, it is easy for the elevator door to fail to open.

[0003] In the prior art, a Chinese patent document with the authorization announcement number CN216918202U records an auxiliary opening mechanism for elevator door detection. The patent includes two sets of fixed seats, a lead screw, a rotating handle, two sets of movable seats, two sets of card plates, multiple sets of screws, multiple sets of limit seats and two sets of adsorption mechanisms. Two sets of fixed seats are respectively provided with two sets of fixing holes, and the two ends of the lead screw pass through the two sets of fixing holes respectively and are rotatably connected to the inner walls of the two sets of fixing holes. The two sets of movable seats are both provided with internal threaded holes corresponding to the lead screws and other structures. When in use, the two sets of card plates are inserted between the elevator car doors. At this time, the fixed seats are adsorbed on the wall where the elevator door is installed through the two sets of adsorption mechanisms to play a reinforcement role. The rotating handle is rotated to rotate the lead screw, driving the two sets of movable seats to move away from each other in the direction of the lead screw, so that the two sets of card plates apply thrust to the elevator door, which can facilitate the opening of the elevator car door.

[0004] When in use, both sets of card plates need to be inserted between the elevator car doors. The gap between the car doors is difficult for the card plates to be directly inserted. During insertion, the car doors will be squeezed and deformed to a certain extent. When in use, the handle needs to be turned manually, which is not convenient in actual use. For this reason, we propose an auxiliary opening mechanism for elevator car doors for inspection. Utility Model Content
