[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1-5, A multi - section telescopic sliding guide rail, including a first guide rail body 1. A second guide rail body 8 is movably connected inside the first guide rail body 1. Chutes 2 are opened at both ends inside the first guide rail body 1 and the second guide rail body 8. Sliders 3 are arranged outside the first guide rail body 1 and the second guide rail body 8. A limiting block 11 is fixedly connected to one end of the slider 3 close to the middle. A limiting mounting frame 5 is arranged on one side of the first guide rail body 1 and the second guide rail body 8 close to the outside, and a structure for facilitating installation and disassembly is arranged inside the limiting mounting frame 5;

[0026] The installation and disassembly structure includes a connecting block 6, a fixing groove 9 and a spring 13. Connecting blocks 6 are fixedly connected to one side of the first guide rail body 1 and the second guide rail body 8 close to the outside. A second guide rail body 8 is opened inside the limiting mounting frame 5. Movable plates 12 are arranged at the upper and lower ends inside the limiting mounting frame 5. A spring 13 is fixedly connected between the movable plates 12. A damper 15 is arranged inside the spring 13. A limiting rod 14 is fixedly connected to one end of the movable plate 12 close to the middle side. Reserved slots 10 are opened at the upper and lower ends inside the connecting block 6;

[0027] The limiting block 11 is arranged inside the chute 2, and the limiting block 11 slides inside the chute 2. The connecting block 6 is embedded inside the fixing groove 9, and the limiting rod 14 is embedded inside the reserved slot 10;

[0028] Specifically, as Figure 1 and Figure 3 shown, when it is necessary to install the limiting mounting frame 5 outside the first guide rail body 1 and the second guide rail body 8, pull the movable plate 12. The movable plate 12 drives the limiting rod 14 to move outward. Then place the limiting mounting frame 5 outside the connecting block 6. After placing it well, release the movable plate 12. The spring 13 makes the limiting rod 14 embedded inside the reserved slot 10 through its own elasticity, so that the limiting mounting frame 5 can be installed and fixed on one side outside the first guide rail body 1 and the second guide rail body 8. The mounting plate at the bottom of the limiting mounting frame 5 is installed at a suitable position. The limiting mounting frame 5 can also limit the slider 3 to prevent the slider 3 from moving excessively.

[0029] Embodiment 2: Installation slots 7 are opened at the front and rear ends on the left side inside the slider 3. An installation block 17 is arranged inside the installation slot 7. A cleaning plate 4 is fixedly connected to the right side of the installation block 17. A cleaning brush 16 is fixedly connected to one end of the cleaning plate 4 close to the middle. An installation hole 18 is opened inside the installation block 17. An installation bolt 19 is arranged inside the installation hole 18. The installation block 17 is embedded inside the installation slot 7, and the installation block 17 is fixed inside the installation slot 7 through the installation hole 18 and the installation bolt 19;

[0030] Specifically, as Figure 1 、 Figure 4 and Figure 5As shown, when the slider 3 moves, the cleaning brush 16 at one end of the cleaning plate 4 will move inside the sliding groove 2, so as to clean the inside of the sliding groove 2, prevent too many impurities inside the sliding groove 2 from affecting the movement of the slider 3. When it is necessary to disassemble and replace the cleaning brush 16, the mounting bolt 19 is screwed out from the inside of the mounting hole 18 to make the mounting block 17 lose its fixation. When the mounting block 17 loses its fixation, the cleaning plate 4 can be disassembled to replace the cleaning brush 16.

[0031] Embodiment 3: The bottom end of the second guide rail body 8 is fixedly connected with a connecting plate 20. A rolling groove 22 is formed at the bottom end inside the connecting plate 20. A plurality of balls 21 are arranged inside the rolling groove 22. A plurality of sets of balls 21 and rolling grooves 22 are provided, and the balls 21 roll inside the rolling grooves 22.

[0032] Specifically, as Figure 1 and Figure 5 shown, setting the first guide rail body 1 and the second guide rail body 8 can facilitate working in different areas. During transportation, the second guide rail body 8 is arranged inside the first guide rail body 1, so as to reduce the occupied area. When the second guide rail body 8 moves inside the first guide rail body 1, the balls 21 inside the rolling groove 22 can reduce the friction between the connecting plate 20 and the first guide rail body 1, so as to facilitate the movement of the second guide rail body 8 inside the first guide rail body 1.

[0033] Working principle: When the present utility model is in use, the first guide rail body 1 and the second guide rail body 8 can facilitate working in different areas. During transportation, the second guide rail body 8 is arranged inside the first guide rail body 1, so as to reduce the occupied area. When the second guide rail body 8 moves inside the first guide rail body 1, the balls 21 inside the rolling groove 22 can reduce the friction between the connecting plate 20 and the first guide rail body 1, so as to facilitate the movement of the second guide rail body 8 inside the first guide rail body 1. When it is necessary to install the limit mounting frame 5 outside the first guide rail body 1 and the second guide rail body 8, the movable plate 12 is pulled, the movable plate 12 drives the limit rod 14 to move outward, and then the limit mounting frame 5 is placed outside the connecting block 6. After placing it, the movable plate 12 is released, and the spring 13 makes the limit rod 14 fit into the reserved groove 10 through its own elasticity, so that the limit mounting frame 5 can be installed and fixed on one side outside the first guide rail body 1 and the second guide rail body 8. The mounting plate at the bottom end of the limit mounting frame 5 is installed at a suitable position. The limit mounting frame 5 can also limit the slider 3 to prevent the slider 3 from moving excessively. When the slider 3 moves, the cleaning brush 16 at one end of the cleaning plate 4 will move inside the sliding groove 2, so as to clean the inside of the sliding groove 2 and prevent too many impurities inside the sliding groove 2 from affecting the movement of the slider 3.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
