Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 The present invention provides an embodiment of a segmented splicing sliding door load-bearing guide rail, comprising a first guide rail segment 1, a second guide rail segment 2, a fixing groove 3 and a plug rod 5. The second guide rail segment 2 is provided on one side of the first guide rail segment 1, and the fixing groove 3 and the fixing part 4 are respectively provided at the top ends of the first guide rail segment 1 and the second guide rail segment 2.

[0023] The fixing groove 3 and the fixing part 4 are respectively fixed to the top of the first guide rail section 1 and the second guide rail section 2 by the mounting ears 15, and the fixing groove 3 and the fixing part 4 are located on the same horizontal line;

[0024] The inside of the fixed groove 3 is movably inserted in the horizontal direction with a rod 5, and a movable ring 13 is provided on the rod 5. The movable ring 13 is fixedly connected to the rod 5, and a lever 6 is provided on the top of the movable ring 13.

[0025] A spring sleeve 9 is fitted on the outside of the insertion rod 5 on one side of the movable ring 13, and one end of the spring sleeve 9 is welded and fixed to the movable ring 13. The other end of the spring sleeve 9 is welded and fixed to the side of the fixing groove 3. A slot 11 corresponding to the insertion rod 5 is opened on the side of the fixing part 4 near the insertion rod 5.

[0026] The operator prepares the first guide rail section 1 and the second guide rail section 2 to be spliced. The operator moves the movable ring 13 away from the fixed part 4 by using the lever 6. The movable ring 13 drives the insertion rod 5 to move horizontally in the fixed groove 3. At this time, the movable ring 13 compresses the spring sleeve 9, so that the end of the insertion rod 5 is retracted into the fixed groove 3. During this process, the guide blocks 10 on both sides of the movable ring 13 slide in the guide groove 14 inside the fixed groove 3 to ensure that the insertion rod 5 moves smoothly.

[0027] Push the first guide rail segment 1 and the second guide rail segment 2 closer to each other until they are connected. The first guide rail segment 1 is provided with positioning protrusions 7 at the four corners on the side of the second guide rail segment 2, and the second guide rail segment 2 is provided with positioning grooves 8 that match the positioning protrusions 7 at the four corners on the side of the first guide rail segment 1.

[0028] After the first guide rail segment 1 and the second guide rail segment 2 are connected, the positioning protrusion 7 is embedded in the positioning groove 8, which provides accurate initial positioning for the splicing of the first guide rail segment 1 and the second guide rail segment 2, ensuring that the fixing groove 3 and the fixing part 4, the plug rod 5 and the slot 11 and other components can be accurately aligned, reducing the adjustment time during the splicing process and improving the splicing efficiency and accuracy.

[0029] Then, the lever 6 is released, and the spring sleeve 9 returns to its original position under its own elastic force, pushing the movable ring 13 and the insertion rod 5 to move closer to the fixed part 4, so that the insertion rod 5 is inserted into the slot 11 on the fixed part 4;

[0030] A magnet 12 is provided on one side inside the slot 11, and the insertion rods 5 are all made of magnetic material. After the insertion rods 5 are inserted into the slot 11, they are attracted and fixed with the magnet 12.

[0031] The magnet 12 on one side of the slot 11 will attract the plug 5, further enhancing the connection between the plug 5 and the slot 11, and completing the splicing of the first guide rail section 1 and the second guide rail section 2.

[0032] This allows the main body of the guide rail to be disassembled into multiple smaller segment units for transportation, effectively solving the problems of limited space and easy deformation during the transportation of integral guide rails. The assembled guide rail body can be connected to the ceiling through the mounting bracket.

[0033] Two sets of limiting ribs 19 are provided at the top of the first guide rail section 1 and the second guide rail section 2, and wear-resistant strips 16 are provided in the first guide rail section 1 and the second guide rail section 2 between the limiting ribs 19. The wear-resistant strips 16 are made of polytetrafluoroethylene.

[0034] The sliding door's pulley moves inside the first guide rail section 1 and the second guide rail section 2. The wear-resistant strip 16 at the top of the guide rail contacts the pulley, utilizing the properties of polytetrafluoroethylene to reduce friction and wear. The limiting rib 19 limits the pulley, ensuring the smooth operation of the sliding door.

[0035] Both sides of the top of the wear-resistant strip 16 are provided with locking blocks 18, and the top of the first guide rail section 1 and the second guide rail section 2 are provided with locking grooves 17 that match the locking blocks 18.

[0036] The cooperation between the locking block 18 and the locking slot 17 further enhances the connection between the wear-resistant strip 16 and the guide rail, preventing the wear-resistant strip 16 from loosening or falling off due to long-term use or vibration. This connection method also facilitates the installation and replacement of the wear-resistant strip 16. When the wear-resistant strip 16 is worn to a certain extent, it can be easily removed and replaced, reducing maintenance costs.

[0037] Both the first guide rail section 1 and the second guide rail section 2 are made of high-strength aluminum alloy, which is lightweight, high-strength, and corrosion-resistant. Both the first guide rail section 1 and the second guide rail section 2 have openings 20 at their bottom ends, providing space for the installation and operation of related components of the sliding door, and facilitating the assembly and maintenance of the sliding door.

[0038] Working Principle: In this embodiment, the operator prepares the first guide rail segment 1 and the second guide rail segment 2 to be spliced. Using the lever 6, the operator moves the movable ring 13 away from the fixed part 4. The movable ring 13 drives the insertion rod 5 to move horizontally within the fixed groove 3. At this time, the movable ring 13 compresses the spring sleeve 9, causing the end of the insertion rod 5 to retract into the fixed groove 3. During this process, the guide blocks 10 on both sides of the movable ring 13 slide within the guide groove 14 inside the fixed groove 3, ensuring smooth movement of the insertion rod 5. The first guide rail segment 1 is brought close to the second guide rail segment 2, aligning the positioning protrusions 7 at the four corners of one side of the first guide rail segment 1 with the corresponding positioning grooves 8 at the four corners of one side of the second guide rail segment 2. Simultaneously, the fixed groove 3 at the top of the first guide rail segment 1 is aligned with the fixed part 4 at the top of the second guide rail segment 2, ensuring they are on the same horizontal line. The first guide rail segment 1 is then pushed... Section 1 and the second guide rail section 2 approach each other, so that the positioning protrusion 7 is inserted into the positioning groove 8 to achieve initial positioning. Release the lever 6, and the spring sleeve 9 resets under its own elastic force, pushing the movable ring 13 and the insertion rod 5 to move towards the fixed part 4, so that the insertion rod 5 is inserted into the slot 11 on the fixed part 4. Since the insertion rod 5 is made of magnetic material, the magnet 12 on one side of the slot 11 will attract the insertion rod 5, further enhancing the connection between the insertion rod 5 and the slot 11, completing the splicing of the first guide rail section 1 and the second guide rail section 2. After the splicing is completed, the sliding door pulley moves inside the first guide rail section 1 and the second guide rail section 2. The wear-resistant strip 16 at the top of the guide rail contacts the pulley, using the properties of polytetrafluoroethylene to reduce friction and wear. The limiting rib (19) limits the pulley, ensuring the smooth operation of the sliding door.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
