Description

Technical Field

[0001] The utility model relates to the technical field of elevator cars, in particular to an anti-displacement elevator car with a protective structure. Background Art

[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. As a vertical transportation tool, elevators have become important construction equipment in high-rise buildings and public places. With the increasing number of high-rise buildings, the number of elevators is also increasing exponentially. Traditional elevators do not have devices to prevent accidental movement. Accidental movement of elevators with the door open will cause shearing accidents. Therefore, a car with a device to prevent accidental movement is needed to meet people's needs.

[0003] However, most of the existing elevators with protection against accidental movement only have one fixed structure, which cannot completely prevent the elevator from moving. Therefore, we propose an anti-movement elevator with a protective structure. Utility Model Content

[0009] Furthermore, the extrusion assembly includes a first fixed frame, a movable frame, a triangular extrusion plate, a threaded rod, a motor and a worm gear. Two corresponding first fixed frames are fixed on the left and right sides of the car. The first fixed frame is slidably connected to the movable frame inside, and a triangular extrusion plate is fixed to the lower side of the movable frame. The lower end of the triangular extrusion plate is located between two clamping bars corresponding to it. A threaded hole is provided on the upper side of the movable frame, and a threaded rod is threadedly connected to the inner part of the threaded hole. A rotating hole is provided on the upper side of the first fixed frame, and the threaded rod is rotatably connected to the inside of the rotating hole.

[0014] By setting up two extrusion assemblies, its operation can be controlled during the process of opening the car door. In this case, the two extrusion assemblies will reel in the two clamping rods to move and connect with the corresponding clamping slots to initially fix the car. At the same time, it will also drive one end of the four extrusion strips to extrude, so that the other end of the four extrusion strips will deflect and contact with the four anti-skid plates. After contact, the car can be further fixed. In this case, the displacement of the car when opening the door can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS
