Description

Technical Field

[0001] This utility model relates to the field of riot control fence technology, specifically to a riot control fence with adjustable splicing height. Background Art

[0002] Currently, for various densely populated public places, such as subway stations, train stations, performances, large conferences and event squares, it is necessary to guide, block and divert the flow of people. If good on-site management is not carried out, stampedes, crowds and other safety accidents are likely to occur in various large-scale public places, especially some large-scale cultural and artistic performances and concerts.

[0003] Nowadays, order maintenance is essential for large events such as concerts and celebrity meet-and-greets to prevent riots caused by emotional outbursts. However, relying solely on manpower is ineffective, costly, and poses a risk to the safety of maintenance personnel. In these situations, riot barriers are indispensable. These barriers effectively separate participants from maintenance staff, significantly improving both the effectiveness of order maintenance and the safety of the personnel.

[0004] Existing riot control barriers are all welded from high-strength metal, making it impossible to adjust their height according to actual site conditions. Furthermore, existing barriers are often connected by multiple bolts, which is cumbersome during installation and disassembly. Therefore, there is an urgent need to design a riot control barrier with adjustable splicing height to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a riot control fence with adjustable splicing height to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A first guide rod is slidably installed in the sliding groove, and a second guide rod is slidably installed in the installation cavity. Both the first guide rod and the second guide rod are fixedly connected to the extension plate.

[0010] Two fixing plates are provided on one side of the first pillar, and a splicing mechanism is provided inside the second pillar, the splicing mechanism corresponding to the two fixing plates.

[0011] The splicing mechanism includes a bidirectional threaded rod, a threaded slider, a movable plate, and a plug-in rod. The bidirectional threaded rod is rotatably installed at the bottom of the inner wall of the mounting cavity. There are two threaded sliders, two movable plates, and two plug-in rods. The two threaded sliders are respectively threaded onto the periphery of both ends of the bidirectional threaded rod. Two guide grooves are opened on one side of the second support column. The two movable plates are respectively slidably installed in the two guide grooves, and the movable plates are fixedly connected to the threaded sliders. The plug-in rod is fixedly installed on one side of the movable plate.

[0012] A worm gear is rotatably installed inside the mounting cavity. A worm wheel is fixedly installed on the periphery of the middle section of the bidirectional threaded rod.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown in the figure, this utility model provides a height-adjustable riot control fence, including a base 1, a first support column 2, a second support column 3, and a partition 4. A lifting mechanism 5 is provided on the upper side of the partition 4. The lifting mechanism 5 includes a fixed cylinder 18, a lead screw 19, a lifting rod 20, and an extension plate 22. The fixed cylinder 18 is fixedly installed on one side of the partition 4. The lead screw 19 is rotatably installed on the bottom of the inner wall of the fixed cylinder 18. The lifting rod 20 is slidably installed inside the fixed cylinder 18 and is threadedly connected to the lead screw 19. The extension plate 22 is slidably installed on the upper side of the partition 4. The extension plate 22 is fixedly connected to one side of the upper end of the lifting rod 20. The first support column 2 and the second support column 3 are both set on the upper side of the base 1. The partition plate 4 is set between the first support column 2 and the second support column 3. The first support column 2 and the second support column 3 are both provided with support rods 6 between them and the base 1. The upper side of the first support column 2 is provided with a sliding groove. The upper side of the second support column 3 is provided with a mounting cavity 9. The first guide rod 21 is slidably installed in the sliding groove. The second guide rod 23 is slidably installed in the mounting cavity 9. The first guide rod 21 and the second guide rod 23 are both fixedly connected to the extension plate 22.

[0024] Specifically, in this embodiment, a crank handle is rotatably installed on the lower side of the fixed cylinder 18. The crank handle is fixedly connected to the lower end of the lead screw 19. By rotating the crank handle, the lead screw 19 is driven to rotate. The rotation of the lead screw 19 can drive the lifting rod 20 to move up and down along the fixed cylinder 18. The movement of the lifting rod 20 can drive the extension plate 22 to move up and down. The movement of the extension plate 22 can drive the first guide rod 21 and the second guide rod 23 to move up and down. The movement of the first guide rod 21 and the second guide rod 23 along the sliding groove and the mounting cavity 9 respectively can improve the smoothness and stability of the extension plate 22 when it moves. By extending the extension plate 22 out of the partition 4, the height of the riot control barrier can be adjusted, so that the riot control barrier can be adjusted to a suitable height according to different situations.

[0025] In other embodiments, by providing a toothed groove at the lower end of the lead screw 19, when the lead screw 19 is rotated, a matching toothed tool must be inserted into the toothed groove to drive the lead screw 19 to rotate, thereby preventing unauthorized personnel from adjusting the height of the riot control barrier.

[0026] This utility model provides a height-adjustable anti-riot fence. Two fixed plates 8 are provided on one side of the first support column 2. A splicing mechanism 7 is provided inside the second support column 3, corresponding to the two fixed plates 8. The splicing mechanism 7 includes a bidirectional threaded rod 10, a threaded slider 11, a movable plate 12, and a connecting rod 13. The bidirectional threaded rod 10 is rotatably mounted on the bottom of the inner wall of the mounting cavity 9. There are two threaded sliders 11, two movable plates 12, and two connecting rods 13. The two threaded sliders 11 are respectively threaded onto both ends of the bidirectional threaded rod 10. On one side of the second support column 3, there are two guide grooves 17. Two movable plates 12 are slidably installed in the two guide grooves 17 respectively, and the movable plates 12 are fixedly connected to the threaded slider 11. The plug rod 13 is fixedly installed on one side of the movable plate 12. A worm gear 15 is rotatably installed in the mounting cavity 9. A worm wheel 14 is fixedly installed on the periphery of the middle section of the bidirectional threaded rod 10. The worm wheel 14 meshes with the worm gear 15. One end of the worm gear 15 is provided with an internal hexagon socket 16. A through hole is provided on one side of the second support column 3, and the through hole corresponds to the internal hexagon socket 16.

[0027] In another embodiment of this utility model, when splicing two riot control fences, the first support column 2 of one riot control fence is placed together with the second support column 3 of the other riot control fence. The fixing plate 8 on one side of the first support column 2 is aligned with the moving plate 12 and the insert post 15 on one side of the second support column 3. Then, a tool compatible with the internal hexagon socket 16 is inserted into the socket 16. The worm gear 15 is then rotated using this tool, causing it to rotate. The rotation of the worm gear 15 drives the worm wheel 14 to rotate, which in turn drives the bidirectional threaded rod 10 to rotate. The screw-in slider 11 can be moved, and the movement of the screw-in slider 11 can cause the moving plate 12 to slide along the guide groove 17. The movement of the moving plate 12 can cause the insert post 15 to move, so that the insert post 15 moves and inserts into the slot on one side of the fixed plate 16, thereby connecting and fixing the two riot guardrails. When disassembling, the above steps are reversed to separate the insert post 15 from the slot 17 on the fixed plate 16, and the two riot guardrails can be disassembled. The structural characteristics of the worm gear 15 and the worm wheel 14 can achieve self-locking of the bidirectional screw rod 10, thereby improving the stability when the insert post 15 is connected to the slot 17.

[0028] The second guide rod 23 is a hollow rod with a groove on one side. The groove corresponds to the guide slide groove 17. The bidirectional threaded rod 10 and the threaded slider 11 are both located inside the second guide rod 23, thereby avoiding mutual interference when the second guide rod 23 slides or the threaded slider 11 slides.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
