[0002] Elevator guide rails are one of the key components in the elevator system. They are mainly used to support and guide the operation of the elevator car and counterweight to ensure the smooth and safe movement of the elevator. They are elevator components composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. They are divided into three types according to the cross-sectional shape: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails withstand the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc. Usually, elevator guide rails are processed in sections, and the accessories of the elevator guide rails are processed into specified lengths. The elevator guide rail components are spliced into a long straight rail structure at the installation site. The length of the straight rail structure is formed by connecting multiple segmented guide rails of different lengths.
[0003] In traditional elevator guide rail accessories, two adjacent guide rail components are spliced together using strip grooves and concave cuts at one end for insertion and clamping. This splicing method cannot effectively limit the position between the two adjacent guide rail accessories, is inconvenient to operate, and is not very strong. This leads to low stability in the assembly of elevator guide rails and reduces the safety of elevator guide rail use. Therefore, we propose an elevator guide rail assembly to solve the above problems. Utility Model Content

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.
[0021] This utility model provides an elevator guide rail assembly. Figure 1-5As shown, it includes a guide rail body, which is composed of a side panel 1 and a bottom panel 2.

A card limit assembly 8 is provided on one side of the side panel 1. The card limit assembly 8 includes a movable groove 81 and a slide groove 82 provided on one side of the side panel 1. The two slide grooves 82 are located on both sides of the movable groove 81. The interiors of the two slide grooves 82 are fixedly installed with The guide rod 83, the outer wall of the guide rod 83 is provided with a return spring 84, and the end of the guide rod 83 close to the return spring 84 is movably connected with a slider 85, and a moving block 86 is fixedly connected between the two sliders 85. One side of the moving block 86 is fixedly connected with a clamping column 87, and the clamping column 87 extends through the side plate 1 to the inside of the socket 13. The other side of the moving block 86 is fixedly connected with a connecting rod 88, and the other end of the connecting rod 88 is fixedly connected with a pull block 89. The slider 85 and the slide groove 82 form a sliding connection structure, and the moving block 86 and the pull block 89 both form a sliding connection structure with the moving groove 81. A T-shaped annular pull groove 810 is provided on the side of the pull block 89 away from the connecting rod 88.
[0022] When the two guide rail assemblies are connected, the guide rail assemblies are fixed, and then the insertion rod 11 on the other guide rail assembly is inserted along the insertion hole 13. During the insertion process, the bottom end of the insertion rod 11 first contacts the clamping column 87, so that the reset spring 84 is first compressed and then reset, so that the clamping column 87 is inserted into the clamping hole 12 for clamping. The clamping and positioning between the two side plates 1 on the two guide rail assemblies can be quickly completed, so that the connection stability is high. At the same time as the insertion rod 11 is inserted into the insertion hole 13, the positioning rod 9 is inserted along the positioning hole 10, which also facilitates the rapid clamping and positioning between the two bottom plates 2 on the two guide rail assemblies. When the guide rail assembly needs to be disassembled and maintained, it is only necessary to pull the pull block 89 outward to drive the moving block 86 to move outward, thereby driving the two sliders 85 to move outward along the slide groove 82, and then driving the clamping column 87 to move outward and disengage from the clamping hole 12, and then the guide rail assembly can be directly removed.
[0023] Furthermore, a splicing interface four 6 is opened at the bottom of one side of the side panel 1, and positioning rods 9 are symmetrically fixedly connected at both ends of the top of the splicing interface four 6 of the bottom panel 2.

[0025] Furthermore, the second joint 4 is adapted to the first joint 3, the insertion rod 11 is adapted to the insertion hole 13, the clamping column 87 is adapted to the clamping hole 12, and the outer ends of the clamping hole 12 and the clamping column 87 are both rounded. When in use, by rounding the outer ends of the clamping hole 12 and the clamping column 87, it is convenient for the clamping column 87 to be clamped in the clamping hole 12, thereby making the connection between the side panel 1 more stable.
[0026] Furthermore, the bottom plate 2 is symmetrically provided with mounting holes 7 on both sides of the top of the side plate 1 . When in use, the guide rail assembly can be conveniently installed through the mounting holes 7 .
[0027] The working principle of the present invention is as follows: when using, when splicing two adjacent guide rail assemblies, one of the guide rail assemblies is fixed, and then the insertion rod 11 on the other guide rail assembly is inserted along the insertion hole 13. During the insertion process, the bottom end of the insertion rod 11 first contacts the clamping column 87, so that the reset spring 84 is first compressed and then reset, so that the clamping column 87 is inserted into the clamping hole 12 for clamping, and the clamping and positioning between the two side plates 1 on the two guide rail assemblies can be quickly completed, so that the connection stability is high, and when the insertion rod 11 is inserted into the insertion hole 13, the positioning rod 9 is inserted along the positioning hole 10, which also facilitates the rapid clamping and positioning between the two bottom plates 2 on the two guide rail assemblies.
[0028] When the guide rail assembly needs to be disassembled and maintained, it is only necessary to pull the pull block 89 outward to drive the moving block 86 to move outward, thereby driving the two sliders 85 to move outward along the slide groove 82, and then driving the clamping column 87 to move outward and disengage from the clamping hole 12, and then the guide rail assembly can be directly removed.
