[0002] Elevator floor doors are generally composed of doors, guide rails, pulleys, sliders, door frames, sills and other components. Floor doors should be doors without holes, and the net height should not be less than 2m. After the floor doors are closed, the gaps between the door leaves and between the door leaves and the columns, lintels and sills should be as small as possible.

[0003] The opening and closing of the floor door is achieved by the door opening blade installed on the car door. Each floor door is equipped with a door lock. After the floor door is closed, the mechanical lock hook of the door lock is engaged, and at the same time, the electrical interlocking contacts of the floor door and the car door are closed, and the elevator control circuit is connected. Only then can the elevator start running.

[0004] However, when the existing floor door is installed, since the floor and the track are slidably connected during installation, the floor door will move along the direction of the track until it collides with the two sides of the mounting frame. When the number of collisions is too many, the side edges of the mounting frame will be deformed, and the floor door will also be worn. In addition, the existing installation device cannot be adjusted according to the floor doors of different heights on the market, and can only be installed for a single specified floor door, and has low applicability.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
