Description

Technical Field

[0001] The utility model relates to the technical field of elevator sliders, in particular to an end cover structure for an elevator guide rail slider. Background Technique

[0002] The guide rail slider in the elevator system is one of the key components responsible for moving on the guide rail. As a part of the slider, the end cover plays a key role in the movement on the guide rail.

[0003] In the prior art, the traditional end cover is usually installed between the slider and bolts. However, with long-term use, the bolts will experience thread slipping, resulting in loose installation. To enhance the installation firmness of the end cover, the existing end cover structure uses a welding method to directly weld the end cover on the slider. Although welding can improve the installation firmness of the end cover, after long-term use, maintenance personnel cannot disassemble the end cover for maintenance or replacement. Instead, the entire slider and end cover must be replaced, which increases the maintenance cost and reduces the maintenance efficiency.

[0004] Therefore, an end cover structure for an elevator guide rail slider is needed to solve the problems of high cost and low maintenance efficiency during the maintenance of the above-mentioned end cover structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide an end cover structure for an elevator guide rail slider to solve the problems raised in the above background technique.

A plurality of fixing bolts penetrate through the middle of the guide rail. A slider is arranged outside the guide rail. Card slots are opened on both the left and right sides of the slider. End covers are installed on both the left and right sides of the slider. A chute b is opened inside the end cover. Two pressing plates are installed on the inner wall of the chute b. Blocks are installed on the side of the two pressing plates close to each other, and the blocks are inserted into the inner wall of the card slot.

[0007] Preferably, a sliding rod is installed on the inner wall of the chute b. A spring is sleeved outside the sliding rod. Positioning columns are installed on both the front and back sides of the end cover, and the ends of the positioning columns on both the left and right sides close to each other are inserted into the slider.

[0008] Preferably, both ends of the spring are fixedly connected to the sides of the two pressing plates away from the sliding rod, and the pressing plates are slidably connected to the outside of the sliding rod.

[0009] Preferably, sealing rings are installed on the sides of the two end covers close to each other. A plurality of rubber pads are installed on the inner ring of the sealing ring. Insertion slots are opened on both the left and right sides of the slider.

[0010] Preferably, the sealing ring is inserted into the inner wall of the insertion groove, and the rubber pad is inserted into the inner wall of the insertion groove. When the sealing ring is pushed by the end cover to the inner wall of the insertion groove, the rubber pad is in a tensile deformation state.

[0011] Preferably, two chute a are provided on the inner wall of the end cover, and two moving blocks are installed on the lower side of the inner wall of the end cover.

[0012] Preferably, the moving block is in close fit with the guide rail, and the inner wall of the chute a is attached to the outer side of the guide rail.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
