For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0029] Referring to Figures 1-4 , an embodiment provided by the present utility model: a telescopic paper tube rack, including symmetrically arranged left and right brackets 1. One side of each bracket 1 is fixedly connected with a support seat 2. One side of each support seat 2 is slidably connected with a connecting seat 11. A first placing tube 3 is slidably connected inside one of the support seats 2 and the connecting seat 11, and a second placing tube 4 is slidably connected inside the other support seat 2 and the connecting seat 11. The first placing tube 3 is slidably connected inside the second placing tube 4, so that the paper tube rack has a telescopic function. A first spring 5 is arranged inside the first placing tube 3. One end of the first spring 5 is fixedly connected inside the second placing tube 4. The function of the first spring 5 is to provide necessary elastic support so that the structure can be kept stable when adjusting the height of the paper tube rack. A positioning hole 6 is opened inside the first placing tube 3 for ensuring the stable fixation of the paper tube rack at different positions. A fixing block 7 is fixedly connected to the outer wall of the second placing tube 4. A rotating shaft 8 is rotatably connected inside the fixing block 7. A support rod 9 is fixedly connected to the outer wall of the rotating shaft 8. A positioning pin 10 is fixedly connected to the bottom of one side of the support rod 9. The positioning pin 10 is slidably connected inside the positioning hole 6 to realize the locking of the paper tube rack at different lengths. A connecting component is arranged on one side of the connecting seat 11, and the connecting component is used to connect the connecting seat 11 and the support seat 2.

[0030] Specifically, during the use of the paper tube rack, when it is necessary to adjust the lengths of the placing tube 1 and the placing tube 2, first, press one side of the support rod 9. The pressing force is transmitted to the rotating shaft 8 inside the support rod 9, causing the rotating shaft 8 to rotate inside the fixed block 7, so that the other side of the support rod 9 is lifted upward. This action causes the positioning pin 10 connected to the other side of the support rod 9 to slide out of the placing tube 2, releasing the locking state of the placing tube 1. Next, the user can push or pull the placing tube 1 to make it slide inside the placing tube 2. At this time, the placing tube 1 will shrink or stretch accordingly through the first spring 5 inside to adjust the length. When the placing tube 1 moves to the required position, just rotate the support rod 9 back to drive the positioning pin 10 to slide into the corresponding positioning hole 6 inside the placing tube 1, thus achieving stable locking, effectively realizing the telescopic adjustment function of the paper tube rack and improving the convenience of use.

[0031] Refer to Figure 1 、 Figure 5 and Figure 6 As shown in, the connecting component includes a clamping block 12. The clamping block 12 is fixedly connected to one side of the connecting seat 11. A concave hole 13 is formed inside the clamping block 12. A connecting block 14 is fixedly connected inside the support seat 2. A groove 19 is formed inside the connecting block 14. The clamping block 12 is slidably connected inside the groove 19. By moving the clamping block 12 inside the groove 19, the clamping ball 16 is snapped into the concave hole 13 to complete the fixation. A connecting frame 15 is fixedly connected to the top of the connecting block 14. The clamping ball 16 is slidably connected inside the connecting frame 15. The clamping block 12 is in contact with the clamping ball 16. The clamping ball 16 is slidably connected inside the concave hole 13 to achieve a stable locking function. A support column 17 is fixedly connected inside the connecting frame 15. The clamping ball 16 is slidably connected to the outer wall of the support column 17, thereby controlling the sliding position of the clamping ball 16. A second spring 18 is sleeved on the outer wall of the support column 17. One end of the second spring 18 is fixedly connected inside the connecting frame 15, and the other end of the second spring 18 is fixedly connected to the outer wall of the clamping ball 16. When the connecting seat 11 and the support seat 2 are fully buckled, the second spring 18 pushes the clamping ball 16 into the concave hole 13 through elastic resilience, ensuring the firm connection of the components and providing reliable elastic support.

[0032] Specifically, when disassembling and assembling the paper tube rack, first, the connecting seat 11 needs to be pulled outwards. This action will cause the connecting seat 11 to drive the clamping block 12 on one side to disengage from between the clamping beads 16, thus completing the disassembly of the connecting seat 11. During the installation process, first place the placing tube one 3 and the placing tube two 4 inside the support seat 2. Subsequently, fasten the connecting seat 11 to one side of the support seat 2. During this process, the clamping block 12 on one side of the connecting seat 11 will slide into the support seat 2 and contact the clamping beads 16 inside the support seat 2, causing the clamping beads 16 to slide into the connecting frame 15 under the action of force. At the same time, the clamping beads 16 will exert an extrusion force on the second spring 18 on the outer wall, causing the second spring 18 to contract. When the connecting seat 11 and the support seat 2 are fully fastened, the second spring 18 will rebound and push the clamping beads 16 into the concave hole 13 inside the clamping block 12, thus completing the fixation, enabling the paper tube rack to be quickly assembled, facilitating the replacement of the paper tube, and improving the convenience of operation.

[0033] Working principle: When adjusting the lengths of the placing tube one 3 and the placing tube two 4 during the use of this paper tube rack, first press one side of the support rod 9, so that it drives the internally connected rotating shaft 8 to rotate inside the fixed block 7 under force, and then the other side of the support rod 9 will lift upwards, driving the positioning pin 10 connected to the other side to slide out of the placing tube two 4, unlocking the placing tube one 3. Subsequently, by pushing or pulling the placing tube one 3 to slide inside the placing tube two 4, the placing tube one 3 drives the first spring 5 inside it to contract or stretch. When adjusted to the appropriate position, just rotate the support rod 9 back, so that it drives the positioning pin 10 to slide into the corresponding positioning hole 6 inside the placing tube one 3 for locking, thus achieving the effect that the paper tube rack is convenient for telescopic adjustment of the length. When it is necessary to disassemble and assemble the paper tube rack, first pull the connecting seat 11 outwards, so that the connecting seat 11 drives the clamping block 12 on one side to disengage from between the clamping beads 16, and then remove the connecting seat 11 to complete the disassembly. During installation, just place the placing tube one 3 and the placing tube two 4 inside the support seat 2, and then fasten the connecting seat 11 to one side of the support seat 2. During this process, the clamping block 12 on one side of the connecting seat 11 will slide into the support seat 2 and contact the clamping beads 16 inside the support seat 2, causing the clamping beads 16 to slide into the connecting frame 15 under force. At the same time, the clamping beads 16 squeeze the second spring 18 on the outer wall, causing it to contract. When the connecting seat 11 and the support seat 2 are fully fastened, through the rebound of the second spring 18, the clamping beads 16 are pushed to reset, so that the clamping beads 16 slide into the concave hole 13 inside the clamping block 12 to complete the fixation, thus achieving the effect that the paper tube rack can be quickly assembled and is convenient for replacing the paper tube.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
