Description

Technical Field

[0001] The utility model relates to an improvement on the slider structure of an elevator door, in particular to a hidden roller slider. Background Art

[0002] The elevator door is the main entry and exit structure of the elevator. When closed, it serves to isolate the environment between the building and the shaft or between the car and the shaft. When open, it forms a passage for entering and exiting the elevator. The elevator door is mainly divided into floor door and car door. Both floor door and car door are opened and closed by door machine. The door machine is usually on the upper part of the elevator door. The door machine itself has a good guiding effect, so the upper part of the elevator door has a good linear operation effect. The bottom of the elevator door corresponds to the sill. If there is no connection between the elevator door and the sill, an offset in the bottom movement will be formed. Therefore, the bottom of the elevator door is connected to the sill through a slider. The sill forms a guide groove structure and can run along the guide groove. The existing sill structure is mainly grooved upward, and the slider is connected to the guide groove in a straight line. In the impact resistance test, it is easy to come out of the groove. Therefore, the opening and closing of the elevator door will have functional failure problems, so technical improvements are needed. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a hidden roller slider.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is as follows: a slider includes a bent plate and a roller. The sill matched with the slider is formed with a downwardly disposed sliding groove, which is arranged adjacent to the outer edge of the sill. The top of the bent plate is fixed to the bottom of the elevator door. The bent plate extends downward and bends close to the outer edge of the sill. The end of the bent plate folds back upward to form a sliding end. The sliding end is connected to a roller, which rolls within the inner wall of the sliding groove. The slider adopts a bent and hidden structure. Its main sliding structure is hidden at the bottom, which has the function of protecting the sliding structure. At the same time, the roller is used as the sliding contact structure, which can slide with low resistance and has good movement smoothness. Compared with traditional sliders, it has a longer service life.

[0005] Furthermore, the bent plate is formed by bending a steel plate, and mounting holes are formed on the upper portion of the bent plate. The mounting holes are arranged in two or more groups, and the mounting holes in different groups are located at different levels. The bent plate is formed by bending the plate integrally and is adapted to have different mounting holes, so that it can be installed according to the height of the door, and is suitable for installing both the hall door and the car door.

[0006] Furthermore, the roller includes a polyurethane molded bearing and a wheel body. A support body is molded on the sliding end, the polyurethane molded bearing is fixed to the support body, and the wheel body is rotatably connected to the polyurethane bearing. The polyurethane bearing is an integrally molded bearing structure with self-lubricating properties, allowing for long-term operation under low-load conditions.

[0007] Furthermore, the sliding end is formed with an upward anti-tripping latch, which is integrally bent with the bent plate and extends upward into the sliding groove. This anti-tripping latch enhances the release groove function of the elevator door, effectively increasing the reliability of the connection between the slider and the sliding groove, improving the safety of the elevator door, and also meeting the needs of special elevators.

[0008] Furthermore, the upper vertical centerline of the bent plate is collinear with the centerline of the roller, and the centerline of the anti-trip buckle is also collinear with the centerline of the roller. The collinearity of the bent plate's structural centerline with the roller ensures stable roller movement and maintains door operation balance. The anti-trip buckle is an important structural reinforcement and complements the roller's function, so it is also collinear.

[0009] Compared with the existing technology, the present invention has the following advantages and effects: the present design is an improvement on the slider structure of the elevator door, which mainly improves the connection strength between the slider and the sill structure and reduces the sliding resistance, effectively prolongs the service life and improves the anti-slip ability of the elevator door, improves the safety of the elevator, and adopts a hidden structure, with no sliding groove displayed on the surface, which effectively improves the anti-debris ability.
