[0028] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings of the specification.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0031] See Figure 1 and Figure 4 This is a schematic diagram of an elevator slider structure in this embodiment. In this embodiment, a connecting plate 100 is pre-installed on the lower surface of the elevator door panel. The connecting plate 100 has a fitting hole 102, and a slider 200 is fitted into the fitting hole 102. The slider 200 is composed of two identical base blocks. A ball groove 203 is formed inside the slider 200, and the ball groove 203 penetrates the outer surface of the slider 200 to form a circular cut. A rolling ball 206 is placed inside the ball groove 203, and the rolling ball 206 is partially exposed through the circular cut and protrudes from the outer surface of the slider 200. In this embodiment, the slider... The slider 200 is connected to the elevator door panel via a connecting plate 100. The connecting plate 100 is located inside the sill, but its thickness is less than that of the sill groove on the sill. When the slider 200 is assembled on the connecting plate 100, the ball 206 inside the slider 200 contacts the inner surface of the sill groove. During the movement of the elevator door panel, the rolling of the ball 206 can reduce the friction between the slider 200 and the sill. This low-friction design helps to improve the smoothness of the elevator door panel movement, reduce energy loss, and reduce wear caused by friction, thus extending the service life of the slider and related components.

[0032] See Figure 2 and Figure 7The mounting hole 101 has the same height as the height of the sliding block 200, and the length of the mounting hole 101 is twice the length of the embedded hole 102. The lower surface of one end of the mounting hole 101 is in communication with the upper surface of the embedded hole 102. In the embodiment, the sliding block 200 is assembled with the embedded hole 102 by first placing the sliding block 200 in the mounting hole 101. The sliding block 200 slides in the mounting hole 101, and through the sliding, the sliding block 200 is moved above the embedded hole 102. Then, the sliding block 200 is moved downward, and the sliding block 200 is clamped with the embedded hole 102. The design provides a larger operation space through the mounting hole 101, which facilitates the clamping of the sliding block 200 with the embedded hole 102. Further, in order to ensure that the sliding block 200 is clamped with the embedded hole 102 firmly, a sliding groove 1011 is formed in the lower surface of the mounting hole 101, and a pressing plate 1012 is slidably connected in the sliding groove 1011. When the sliding block 200 is assembled with the embedded hole 102, the pressing plate 1012 is pressed on the upper surface of the sliding block 200. Screw holes are formed in both ends of the pressing plate 1012 and the sliding groove 1011 near the embedded hole 102. When the pressing plate 1012 is covered on the upper surface of the sliding block 200, the screw holes are fixed by screws. The upper surface of the sliding block 200 is provided with a plate groove 202, and the depth of the plate groove 202 is equal to the thickness of the pressing plate 1012. When the sliding block 200 is assembled in the embedded hole 102, the plate groove 202 and the sliding groove 1011 are on the same horizontal plane. The design of the structure of the embedded hole 102 and the mounting hole 101 in the embodiment makes the assembly process of the sliding block 200 have a certain directionality. The sliding block 200 can be accurately installed along the structure of the embedded hole 102 and the mounting hole 101. The lower surface of one end of the mounting hole 101 and the pressing plate 1012 are slid in the sliding groove 1011. When the sliding block 200 is assembled, the pressing plate 1012 can be pressed on the upper surface of the sliding block 200, and the pressing plate 1012 is fixed by the screws and the screw holes. The final fixing operation of the sliding block 200 during assembly can ensure that the sliding block 200 is tightly pressed on the connecting plate 100 after assembly.

[0033] Referring to Figure 5 and Figure 6 The two sides of the sliding block 200 are provided with embedded grooves 201, and the embedded grooves 201 have the same width as the thickness of the connecting plate 100. The sliding block 200 is clamped at the edge of the embedded hole 102 through the embedded grooves 201, so as to be connected to the connecting plate 100, thereby ensuring that the sliding block 200 can be stably installed on the connecting plate 100.

[0034] Referring to Figure 3 and Figure 4The outer surface of the base block of the sliding block 200 is provided with an assembly groove 204, and a clasp 205 is assembled on the assembly groove 204, the base block is tightly adhered through the clasp 205, a circular hole 2051 is provided at the center of the clasp 205, the two base blocks are combined to form an integral whole through the clasp 205, so as to constrain the rolling ball 206 in the ball groove 203, the circular hole 2051 ensures that the rolling ball 206 partially protrudes outward, so as to be capable of contacting the inner surface of the sill, when the elevator door is opened and closed, the rolling of the rolling ball 206 is utilized to reduce the friction, further, through holes are provided at the clasp 205 and the four corners of the sliding block 200, and bolts 207 are arranged in the through holes, the clasp 205 and the sliding block 200 are formed into an integral whole through the bolts 207.

[0035] The above is further detailed description of the utility model in combination with the specific implementation, and cannot be determined that the specific implementation of the utility model is limited to these descriptions, for the ordinary skilled in the art to which the utility model belongs, on the premise of not departing from the concept of the utility model, a number of simple deductions or substitutions can also be made, and all should be regarded as belonging to the protection scope determined by the claims submitted by the utility model.
