Description

Technical Field

[0001] The utility model relates to the technical field of elevator anti-collision, in particular to an elevator corner anti-collision structure. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. During the loading process, the goods need to be moved to the inside of the freight elevator. During the transportation, the goods are prone to collide with the inner wall of the freight elevator, so an elevator corner anti-collision structure is required.

[0003] A Chinese patent with authorization publication number CN213059793U discloses an anti-collision structure for a cargo elevator, comprising a box body, a spring seat connected to one side of the inner wall of the box body, an anti-collision mechanism connected to one side of the spring seat, the interior of the spring seat comprising a first base connected to one side of the box body, a spring connected to one side of the first base, a telescopic rod sleeved inside the spring, a second base connected to the other side of the first base, a slide rail connected to one side of the second base, a slider connected to one side of the anti-collision mechanism, a pressure sensor embedded in the other side of the anti-collision mechanism, a second screw hole provided at the bottom of the anti-collision mechanism, a roller connected at the bottom of the anti-collision mechanism, the utility model reduces the force of the box body from the cargo through the first base, the spring, the second base, the slide rail and the telescopic rod, which is conducive to reducing the deformation of the elevator box wall.

[0004] Although the above-mentioned anti-collision structure for elevators reduces the force of the box body from the cargo through the first base, spring, second base, slide rail, and telescopic rod, which is beneficial to reduce the deformation of the elevator box wall, the anti-collision structure is relatively fixed. Therefore, after a collision, if part of it is damaged, the anti-collision structure needs to be dismantled and replaced as a whole, which is more troublesome and has a high cost. For this reason, we propose an elevator corner anti-collision structure. Utility Model Content
