Description

Technical Field

[0001] This utility model relates to the field of fence equipment technology, and more specifically, to an adjustable telescopic fence. Background Technology

[0002] Telescopic fences are flexible and adjustable isolation or protection devices, typically made of metal or high-strength plastic. They can be freely extended and retracted, allowing for quick deployment, folding, or length adjustment. These fences are commonly used for temporary isolation, pet areas, garden partitions, or child protection. Combining portability and stability, their compact size when folded makes them easy to store and transport, making them an ideal solution for dynamic space management.

[0003] Traditional telescopic fences typically require manual adjustment of their length. This manual operation necessitates adjusting each fence segment individually, which is time-consuming, labor-intensive, and inefficient. Furthermore, the lack of an automatic locking mechanism after adjustment necessitates additional reinforcement steps, such as pin fixing, bolt tightening, or buckle locking. This lack of flexibility makes it difficult to quickly adjust the length according to actual needs. Utility Model Content

[0016] 3. Beneficial effects

[0017] Compared to existing technologies, this utility model provides an adjustable telescopic fence with the following features:

[0018] Beneficial effects:

[0019] This adjustable telescopic fence works by controlling a servo motor to rotate a transmission threaded rod, which in turn moves a transmission block up and down. The transmission rod then moves a T-shaped self-locking plate up and down. Two self-locking rods cause one sliding end block to slide within corresponding two limit rails, while the other sliding end block also slides synchronously within the corresponding two limit rails, thus extending and retracting the folding rod. This ultimately adjusts the length of the fence body. Once the adjustment is complete and the transmission threaded rod stops rotating, the sliding end block between the two self-locking rods cannot move further due to their restriction. The fence body length can be quickly adjusted electrically, saving operation time and steps. It also achieves self-locking after length adjustment, preventing changes in the preset telescopic length due to wind, collisions, or accidental human intervention, and maintaining good stability.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all 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.

[0029] Example:

[0030] Please see Figures 1-6 An adjustable telescopic fence, comprising:

[0031] Two frame main rods 1, each with a fixed end block 4 fixedly connected to one side of its outer surface, and a set of limiting slide rails 2 fixedly connected to one side of each frame main rod 1, with two of each set of limiting slide rails 2. A self-locking control box 8 is fixedly connected to one side of the outer surface of one frame main rod 1. A transmission threaded rod 11 is rotatably connected between the upper and lower inner walls of the self-locking control box 8. A transmission block 12 is threaded onto the transmission threaded rod 11. A transmission rod 9 is fixedly connected to the bottom of the transmission block 12, and the transmission rod 9 slides through the bottom inner wall of the self-locking control box 8. A T-shaped self-locking plate 6 is fixedly connected to the lower end of the transmission block 12. Two self-locking rods 7 are fixedly connected to one side of the outer surface of the T-shaped self-locking plate 6, and both self-locking rods 7 slide through the corresponding two limiting slide rails 2.

[0032] The folding rod 3 has two ends rotatably connected to the interior of two fixed end blocks 4, and the other two ends of the folding rod 3 are rotatably connected to sliding end blocks 5. Each sliding end block 5 is slidably connected between two corresponding limit slide rails 2, and one of the sliding end blocks 5 is located between two self-locking rods 7.

[0033] In a specific embodiment of this utility model, the folding rod 3, the main frame rod 1, and two sets of limiting slide rail plates 2 constitute the fence body. The length of the fence body is adjusted by extending and retracting the folding rod 3. When the folding rod 3 is extended and retracted, the transmission threaded rod 11 is controlled to rotate, which drives the transmission block 12 to move up and down. The transmission rod 9 drives the T-shaped self-locking plate 6 to move up and down. The two self-locking rods 7 will drive one of the sliding end blocks 5 to slide in the corresponding two limiting slide rail plates 2. The other sliding end block 5 will also slide synchronously on the corresponding two limiting slide rail plates 2, thereby performing the extension and retraction movement of the folding rod 3. Finally, the length of the fence body is adjusted. When the adjustment is completed, the transmission threaded rod 11 stops rotating. The sliding end block 5 between the two self-locking rods 7 cannot move due to the restriction of the two self-locking rods 7. The length of the fence body is quickly adjusted by electric adjustment, saving operation time and steps. At the same time, it also realizes self-locking after the length of the fence body is adjusted, preventing the preset extension and retraction length from changing due to wind, collision or human accidental touch, and maintaining good stability.

[0034] Specifically, a servo motor 10 is fixedly installed on the top of the self-locking control box 8, and the output end of the servo motor 10 is fixedly connected to the transmission threaded rod 11.

[0035] In this embodiment, by controlling the servo motor 10 to start, the transmission threaded rod 11 can be driven to rotate. The output end of the servo motor 10 is fixedly connected to the transmission threaded rod 11 through a coupling or other known components.

[0036] Specifically, transmission rod 9 is made of stainless steel.

[0037] In this embodiment, the transmission rod 9 is exposed to the outside for a long time. It is made of stainless steel, which is not easy to rust and has a long service life.

[0038] Specifically, a limit rod 13 is fixedly connected between the upper and lower inner walls of the self-locking control box 8, and the transmission block 12 is slidably sleeved on the limit rod 13.

[0039] In this embodiment, the limiting rod 13 keeps the transmission block 12 stable during movement.

[0040] Specifically, the limit rod 13 is made of stainless steel.

[0041] In this embodiment, the surface of the limiting rod 13 is smooth, and the friction between it and the transmission block 12 is small.

[0042] Specifically, both main frame rods 1 adopt a hollow design.

[0043] In this embodiment, the frame main rod 1 adopts a hollow design, which can meet the usage requirements while significantly saving costs.

[0044] Working principle: The folding rod 3, the main frame rod 1, and two sets of limiting slide rails 2 form the fence body. The length of the fence body can be adjusted by extending and retracting the folding rod 3. When the folding rod 3 is extended and retracted, the servo motor 10 is started, which drives the transmission threaded rod 11 to rotate, which drives the transmission block 12 to move up and down. The transmission rod 9 drives the T-shaped self-locking plate 6 to move up and down. The two self-locking rods 7 will drive one of the sliding end blocks 5 to slide within the corresponding two limiting slide rails 2. The other sliding end block 5 will also slide synchronously on the corresponding two limiting slide rails 2, thereby performing the extension and retraction movement of the folding rod 3. Finally, the length of the fence body is adjusted. When the adjustment is completed, the transmission threaded rod 11 stops rotating. The sliding end block 5 between the two self-locking rods 7 cannot move anymore due to the restriction of the two self-locking rods 7. The length of the fence body can be quickly adjusted by electric adjustment, saving operation time and steps. At the same time, it also realizes self-locking after the length of the fence body is adjusted, preventing the preset extension and retraction length from changing due to wind, collision or human accidental touch, and maintaining good stability.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
