Abstract
Description
Technical Field
[0001] This utility model relates to the field of skylight pole technology, and in particular to a skylight pole with a telescopic structure. Background Technology
[0002] Canopy poles are important components that support canopies. They are mostly made of materials such as metal, aluminum alloy, or carbon fiber, and have a certain strength and toughness. Their main function is to support the canopy, forming a large outdoor sunshade and rain shelter space, and ensuring the stability of the canopy during use. Canopy poles come in different specifications and lengths, and can be selected and combined according to the size of the canopy and the actual construction needs.
[0003] A canopy pole with a telescopic structure is a special pole used to support a canopy. It can flexibly change its length to adapt to different needs. Based on the internal nested telescopic joint design, the relative position between each section can be adjusted by inserting, pulling or rotating to achieve telescopic extension. This design allows the canopy pole to reduce its volume when stored and to extend to the appropriate length as needed when setting up the canopy, providing stable support.
[0004] In existing technologies, some tarpaulin poles, due to their traditional fixed length, are inadequate for diverse outdoor terrains. In open grasslands, large tarpaulins require long poles for support to expand the space, but existing short poles are insufficient, resulting in cramped tarpaulin setups and limited activity areas. In narrow forests, long poles are difficult to maneuver due to insufficient space, hindering successful setup and forcing people to abandon ideal camping locations. Therefore, a tarpaulin pole with a retractable structure is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a canopy pole with a retractable structure, which aims to improve the problem of cramped canopy construction and limited activity area in the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A telescopic canopy pole includes a pole body, a fixing ring fixedly connected to the outside of the pole body, fixing posts fixedly connected to the front and rear sides of the fixing ring, a connecting groove opened inside the fixing post, a connecting post slidably connected inside the connecting groove, a spring sleeved on the outside of the connecting post, a screw threadedly connected to the inner wall of the connecting post, a connecting block threadedly connected to the outside of the screw, an upper collar fixedly connected to the adjacent side of two connecting blocks, a connecting block fixedly connected to the bottom of the connecting post, a lower collar fixedly connected to the adjacent side of two connecting blocks, a limit post fixedly connected to the top inner wall of the upper collar, a connecting rod slidably connected inside the pole body, a plurality of limit holes opened inside the connecting rod, and a portable component for reinforcing the canopy pole slidably connected inside the connecting rod.
[0008] As a further description of the above technical solution:
[0009] The portable component includes a connecting rod, a connecting ring is fixedly connected to the outside of the connecting rod, and two fixing grooves are opened inside the connecting ring. A spring is fixedly connected to the left inner wall of the fixing groove.
[0010] As a further description of the above technical solution:
[0011] The top of the first spring is in contact with the top inner wall of the connecting groove, and the bottom of the first spring is in contact with the top of the connecting block.
[0012] As a further description of the above technical solution:
[0013] The outer side of the limiting post is in contact with the inner wall of the limiting hole, and the inner wall of the upper collar is in contact with the outer side of the fixing ring.
[0014] As a further description of the above technical solution:
[0015] The bottom of the connecting block is in contact with the top of the fixing post, and the top of the lower collar is in contact with the outside of the fixing ring;
[0016] As a further description of the above technical solution:
[0017] A T-shaped block is fixedly connected to the right side of the second spring, and two U-shaped hooks are fixedly connected to the outside of the connecting ring;
[0018] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by pressing the lower collar inward, the lower collar drives the connecting column to rise through the connecting block, causing the screw to push the connecting block and the upper collar upward. At this time, the limiting column disengages from the limiting hole on the connecting rod, the lower collar is released, and the elastic force of the spring pushes the connecting column and the lower collar and other components to reset. The limiting column re-engages into the limiting hole, thus achieving a simple and direct installation method. By using common components such as springs, connecting columns, and screws, the length adjustment is flexible. Pressing the lower collar unlocks it, and it automatically resets and fixes itself after being released. The limiting is precise, providing a stable and convenient telescopic function for the canopy pole.
[0024] 2. In this utility model, when the gravity of the skylight acts on the U-shaped hook, the T-shaped block is tightly inserted into the inner wall of the U-shaped hook under the elastic force of the second spring. When the operator pulls the lever, the T-shaped block is disengaged from the U-shaped hook, and the second spring causes the T-shaped block to be inserted back into the U-shaped hook. Thus, the greater the gravity, the tighter the T-shaped block is inserted into the U-shaped hook, which significantly enhances the stability of the skylight pole. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3 One embodiment of this utility model is a canopy pole with a telescopic structure, including a pole body 1. The pole body 1 provides fixation and support for a fixing ring 2. The fixing ring 2 is fixedly connected to the outside of the pole body 1. The fixing ring 2 provides fixation and support for a fixing column 3. The fixing columns 3 are fixedly connected to the front and rear sides of the fixing ring 2 respectively. The fixing columns 3 provide space for opening a connecting groove 4.
[0034] Reference Figure 3 and Figure 4 The fixed column 3 has a connecting groove 4 inside, which provides a limiting and guiding function for the connecting column 5. The connecting column 5 is slidably connected inside the connecting groove 4. When installing the canopy rod, a spring 6 is sleeved on the outside of the connecting column 5 and then inserted into the inside of the connecting groove 4. The spring 6, which has an elastic function, provides elastic support for the connecting column 5. A screw 7 is threaded on the inner wall of the connecting column 5, and the screw 7 is screwed into the inside of the connecting column 5 to complete the connection and fixation of the connecting block 8 and the connecting column 5. Due to the elasticity of the spring 6, the upper collar 9 is pulled and inserted into the outside of the fixed ring 2. The connecting block 8 is threaded on the outside of the screw 7, and the connecting block 8 provides fixation and support for the upper collar 9.
[0035] An upper collar 9 is fixedly connected to one side of the two connecting blocks 8. The connecting post 5, through the elastic action of spring 6 and screw 7, pulls the connecting block 8 to clamp the top of the connecting post 5, thereby causing the upper collar 9 to clamp the outside of the fixing ring 2. A connecting block 10 is fixedly connected to the bottom of the connecting post 5, providing fixation and support for the connecting post 5. A lower collar 11 is fixedly connected to one side of the two connecting blocks 10. The lower collar 11 receives the elastic action from spring 6, and is then moved by the connecting block 10. 11 Slide outwards, and the upper collar 9 is fixedly connected to the inner wall of the top with a limiting post 12. When the upper collar 9 is pulled to clamp the outside of the fixed ring 2, the limiting post 12 is driven to clamp the inside of the limiting hole 14. The inside of the rod body 1 is slidably connected to a connecting rod 13. The connecting rod 13 can extend and retract the canopy rod. The inside of the connecting rod 13 is provided with multiple limiting holes 14. The limiting holes 14 and the limiting post 12 cooperate to complete the limiting and fixing of the connecting rod 13. The inside of the connecting rod 13 is slidably connected to a portable component that facilitates the reinforcement of the canopy rod.
[0036] Reference Figure 2 and Figure 5 The portable component includes a connecting rod 15, which provides fixation and support for the connecting ring 16. The connecting rod 15 is a secondary telescopic rod of the canopy rod. The connecting ring 16 is fixedly connected to the outside of the connecting rod 15. The connecting ring 16 provides space for the fixing groove 17. Two fixing grooves 17 are opened inside the connecting ring 16. The fixing grooves 17 provide fixation and support for the second spring 18. The second spring 18 is fixedly connected to the left inner wall of the fixing groove 17. The second spring 18 has an elastic function and provides elastic support for its T-block 19.
[0037] Reference Figures 1 to 3 The top of spring 6 contacts the inner wall of the top of the connecting groove 4. When it is necessary to adjust the length of the connecting rod 13 or the connecting rod 15, the lower collar 11 is pressed inward, and the connecting block 8 and the upper collar 9 are lifted by the connecting post 5 and the screw 7, so that the limiting post 12 is disengaged from the inside of the limiting hole 14, thus completing the length adjustment of the connecting rod 13 or the connecting rod 15. The bottom of spring 6 contacts the top of the connecting block 10. After the adjustment is completed, the lower collar 11 is released. Through the elastic action of spring 6, the connecting post 5 and the lower collar 11 are pushed back to their original positions. Then, the upper collar 9 is driven back to its original position by the screw 7, and the limiting post 12 is driven into the inside of the limiting hole 14.
[0038] The outer side of the limiting post 12 contacts the inner wall of the limiting hole 14. Similarly, the limiting hole 14 and the limiting post 12 cooperate to limit and fix the connecting rod 13 or the connecting rod 15. The inner wall of the upper collar 9 contacts the outer side of the fixing ring 2. The upper collar 9 receives the elastic force from the spring 6 on the connecting post 5 through the screw 7, thereby clamping the outer side of the fixing ring 2. The bottom of the connecting block 8 contacts the top of the fixing post 3. The connecting post 5 is pulled by the screw 7 through the elastic action of the spring 6 to clamp the top of the fixing post 3. The top of the lower collar 11 contacts the outer side of the fixing ring 2. When the length needs to be adjusted, the lower collar 11 is pressed, thereby driving the connecting post 5 to rise. A T-shaped block 19 is fixedly connected to the right side of the spring 18. The T-shaped block 19 is used to clamp the inside of the U-shaped hook 21 through the elastic action of the spring 18. Two U-shaped hooks 21 are fixedly connected to the outside of the connecting ring 16. The U-shaped hooks 21 are used to support the canopy.
[0039] The outer rear side of the T-block 19 is slidably connected to the inside of the fixing groove 17. The fixing groove 17 provides a limiting and guiding function for the T-block 19. The outer side of the T-block 19 is in contact with the inner wall of the U-hook 21. When the U-hook 21 is subjected to the gravity from the canopy, the T-block 19 will clamp onto the inner wall of the U-hook 21. The greater the gravity, the tighter the T-block 19 is clamped. A lever 20 is fixedly connected to the left side of the T-block 19. The operator can pull the lever 20 outward to move the T-block 19 away from the inside of the U-hook 21 so that the canopy can be placed in for connection. The elasticity of the spring 18 causes the T-block 19 to be clamped into the inside of the U-hook 21. The outer side of the connecting rod 15 is slidably connected to the inside of the connecting rod 13. The connecting rod 13 provides a limiting and guiding function for the connecting rod 15.
[0040] Working principle: When installing the telescopic component, first put the spring 6 on the connecting post 5, then slide the connecting post 5 into the connecting groove 4 of the fixing post 3. The top of the connecting post 5 is connected to the connecting block 8 with the screw 7. When the length of the connecting rod 13 needs to be adjusted, press the lower collar 11 inward. The lower collar 11 drives the connecting post 5 to rise through the connecting block 10, so that the screw 7 pushes the connecting block 8 and the upper collar 9 to move upward. At this time, the limiting post 12 disengages from the limiting hole 14 on the connecting rod 13, and the connecting rod 13 or the connecting rod 15 can be freely telescopic. After the adjustment is finished, release the lower collar 11. The elastic force of the spring 6 pushes the connecting post 5 and the lower collar 11 and other components to reset. The limiting post 12 re-engages into the limiting hole 14, completing the limiting and fixing of the connecting rod 13.
[0041] When reinforcement of the canopy pole is required, the connecting rod 15 serves as a secondary telescopic rod, with the external fixed connecting ring 16. When the gravity of the canopy acts on the U-shaped hook 21, the T-shaped block 19 is tightly locked into the inner wall of the U-shaped hook 21 under the elastic force of the second spring 18. The greater the gravity, the stronger the locking force. When installing the canopy, the operator pulls the lever 20 to move the T-shaped block 19 away from the U-shaped hook 21. After the canopy installation is completed, the second spring 18 causes the T-shaped block 19 to lock back into the U-shaped hook 21, thus reinforcing the canopy pole.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
