Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a structurally stable anti-climb guardrail mesh. Background Technology

[0002] Fences, also known as protective netting, are mainly divided into garden fences, railway fences, bridge fences, highway fences, sports fences, airport fences, etc. They are widely used and their main function is...

[0003] Patent document CN217897512U discloses an anti-climb fence, comprising a first fixed post, a second fixed post, and a fence body. Each of the first and second fixed posts has a connecting slot on one side. A connecting block is fixedly connected to one side of the fence body. A spike mounting seat is fixedly connected to the top of the fence body. Several mounting grooves are formed on one side of the spike mounting seat, and the inner walls of these mounting grooves have connecting grooves. The advantage of this invention is that, through the coordinated arrangement of the mounting grooves, connecting grooves, spike mounting blocks, spikes, fixing blocks, fixing holes, rotating shafts, knobs, threads, moving blocks, and fixing rods, the spikes are no longer fixedly connected. This simplifies the process of replacing the spikes, greatly saving time and improving the efficiency of spike replacement.

[0004] The anti-climb fences proposed in the above patent documents, in actual use, only have a single row of spikes at the top of the fence, and the protective range of the spikes is limited, resulting in a very limited anti-climb range at the top of the fence, which cannot achieve a better anti-climbing purpose. Therefore, we have improved the existing anti-climb fence technology. Utility Model Content

[0005] This utility model discloses a structurally stable anti-climb guardrail. To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A structurally stable anti-climb fence includes a base, on the upper surface of which two support columns are fixedly connected. The top of the two support columns is provided with a rectangular mounting groove, and an anti-climb component is inserted and installed inside the rectangular mounting groove.

[0007] The anti-climb component includes a limiting support block, a V-shaped fixing frame is fixedly connected to the top of the limiting support block, two limiting mounting rods are fixedly connected between the two fixing frames, and a positioning frame is fixedly connected between the two fixing frames. Several anti-climb rings are fixedly installed between the positioning frame and the limiting mounting rods.

[0008] A micro switch is fixedly connected to the inner bottom wall of the rectangular mounting groove, the limiting support block is slidably connected to the inner wall of the rectangular mounting groove, and an audible and visual alarm is fixedly installed on the surface of the support column.

[0009] In a preferred embodiment, a protective wall panel is fixedly connected between the two supporting columns, and the surface of the protective wall panel has a plurality of strip-shaped through holes.

[0010] In a preferred embodiment, the inner wall of the rectangular mounting groove has two guide grooves that are symmetrically positioned. Guide sliders are fixedly connected to both sides of the limiting support block. The guide sliders are slidably connected to the inner wall of the guide grooves, and a support spring is fixedly provided between the bottom end of the guide slider and the guide groove.

[0011] In a preferred embodiment, the position of the micro switch corresponds to that of the limiting support block, and the micro switch is located directly below the limiting support block.

[0012] In a preferred embodiment, the upper surface of the positioning frame is provided with a plurality of positioning mounting slots, and the bottom of the anti-climb ring is fixedly connected to a positioning mounting block. The positioning mounting block has a U-shaped structure, and the size of the positioning mounting block matches the positioning mounting slot. The positioning mounting block is inserted into the inner wall of the positioning mounting slot.

[0013] In a preferred embodiment, a plurality of spikes are fixedly disposed on the surface of the anti-climb ring, and the plurality of spikes are evenly distributed in a ring array on the outer surface of the anti-climb ring.

[0014] In a preferred embodiment, locking rubber blocks are fixedly connected to both sides of the anti-climb ring. The surface of the locking rubber block has a circular groove that matches the limiting mounting rod. The locking rubber block is fitted onto the surface of the limiting mounting rod through the circular groove. Two locking plates are fixedly connected to the surface of the locking rubber block. Bolt holes are opened on the surface of both locking plates. Locking bolts are threaded into the inner walls of the bolt holes. Limiting nuts are threaded into the surface of the locking bolts.

[0015] As can be seen from the above, the structurally stable anti-climb guardrail provided by this utility model has the following technical effects.

[0016] Firstly, by installing anti-climb components at the top of the support columns, anti-climb rings can be used to block and protect the top of the protective wall panel from climbing. The circular anti-climb rings increase the anti-climb range at the top of the protective wall panel. By installing limit support blocks inside the support columns, when the surface of the fixing frame bears a certain weight, the limit support blocks can be driven downward to contact the micro switch at the bottom of the rectangular mounting groove. This micro switch triggers the audible and visual alarm, achieving an on-site alarm effect and further improving the anti-climbing effect of the guardrail.

[0017] Secondly, by setting guide grooves, guide sliders and support springs in the rectangular mounting slots of the support column, the support springs can support and limit the bottom of the guide sliders, thereby automatically resetting the limit support block. Under normal circumstances, the limit support block maintains a certain distance from the micro switch, which facilitates subsequent anti-climb monitoring and alarm work. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1 and Figure 2 The structurally stable anti-climbing fence includes a base 1, with two support columns 2 fixedly connected to the upper surface of the base 1, and a protective wall panel 5 fixedly connected between the two support columns 2. The surface of the protective wall panel 5 has several strip-shaped through holes 6.

[0027] The top of the two supporting columns 2 is provided with a rectangular mounting groove 3, and an anti-climbing component 4 is inserted and installed inside the rectangular mounting groove 3.

[0028] Reference Figure 3 and Figure 4 In a preferred embodiment, the anti-climb component 4 includes a limiting support block 401. A V-shaped fixing frame 402 is fixedly connected to the top of the limiting support block 401. Two limiting mounting rods 403 are fixedly connected between the two fixing frames 402, and a positioning frame 404 is fixedly connected between the two fixing frames 402. A plurality of anti-climb rings 405 are fixedly installed between the positioning frame 404 and the limiting mounting rods 403. A plurality of spikes 413 are fixedly provided on the surface of the anti-climb rings 405. The plurality of spikes 413 are evenly distributed in a ring array on the outer ring surface of the anti-climb rings 405.

[0029] Several anti-climb rings 405 are arranged in a straight array on the surface of the limiting mounting rod 403, and the distance between two adjacent anti-climb rings 405 does not exceed 20 cm. Therefore, climbing can be prevented, and the spikes 413 on the surface of the anti-climb rings 405 can be used for protection to prevent intruders from touching the anti-climb rings 405 with their hands.

[0030] It is worth noting that by setting an anti-climb component 4 on the top of the support column 2, several anti-climb rings 405 set on the surface of the fixed frame 402 can be used to block and protect the top of the protective wall panel 5 from climbing. It is also convenient for staff to install and replace each anti-climb ring 405 individually, thus facilitating the installation and maintenance of the anti-climb rings 405.

[0031] Reference Figure 4 In a preferred embodiment, the upper surface of the positioning frame 404 is provided with a plurality of positioning mounting slots 411, and the bottom of the anti-climb ring 405 is fixedly connected to a positioning mounting block 412. The positioning mounting block 412 has a U-shaped structure, and the size of the positioning mounting block 412 matches the positioning mounting slot 411. The positioning mounting block 412 is inserted into the inner wall of the positioning mounting slot 411.

[0032] It should be noted that locking rubber blocks 414 are fixedly connected to both sides of the anti-climb ring 405. The surface of the locking rubber block 414 is provided with a circular groove 415 that matches the limit mounting rod 403. The locking rubber block 414 is fitted onto the surface of the limit mounting rod 403 through the circular groove 415. Two locking plates 416 are fixedly connected to the surface of the locking rubber block 414. Bolt holes are provided on the surface of both locking plates 416. Locking bolts 417 are threadedly connected to the inner wall of the bolt holes. Limit nuts 418 are threadedly connected to the surface of the locking bolts 417.

[0033] Reference Figure 5 A micro switch 406 is fixedly connected to the inner bottom wall of the rectangular mounting groove 3. The limiting support block 401 is slidably connected to the inner wall of the rectangular mounting groove 3. An audible and visual alarm 7 is fixedly installed on the surface of the support column 2. The position of the micro switch 406 corresponds to that of the limiting support block 401, and the micro switch 406 is located directly below the limiting support block 401.

[0034] It should be noted that the support column 2 is equipped with a controller, which is electrically connected to the micro switch 406 and the audible and visual alarm 7, and the controller is connected to the external power supply line via a cable.

[0035] It is worth noting that by setting a limiting support block 401 inside the support column 2, when the surface of the fixing frame 402 bears a certain weight, the limiting support block 401 can be driven to contact the micro switch 406 at the bottom of the rectangular mounting groove 3, thereby triggering the sound and light alarm 7 by the micro switch 406 to achieve the effect of on-site alarm and further improve the anti-climbing effect of the guardrail.

[0036] It should be further explained that the inner wall of the rectangular mounting groove 3 has two guide grooves 408 that are symmetrical to each other. Guide sliders 409 are fixedly connected to both sides of the limiting support block 401. The guide sliders 409 are slidably connected to the inner wall of the guide grooves 408, and a support spring 410 is fixedly provided between the bottom end of the guide sliders 409 and the guide grooves 408.

[0037] It is worth noting that by setting a guide groove 408, a guide slider 409 and a support spring 410 in the rectangular mounting groove 3 of the support column 2, the support spring 410 can support and limit the bottom of the guide slider 409, thereby automatically resetting the limit support block 401. Under normal circumstances, the limit support block 401 maintains a certain distance from the micro switch 406, which facilitates subsequent anti-climb monitoring and alarm work.

[0038] Working principle: In use, first, the base 1 is fixedly installed on the ground. Then, the locking rubber blocks 414 on both sides of the anti-climb ring 405 are fitted onto the surface of the limiting mounting rod 403. The positioning mounting block 412 at the bottom of the anti-climb ring 405 is inserted into the positioning mounting groove 411 on the surface of the positioning frame 404. The positioning frame 404 supports and limits the bottom of the anti-climb ring 405. Then, the two locking plates 416 are locked and fixed using the locking bolts 417 and the limiting nuts 418. Thus, the locking rubber blocks 414 lock and bind the limiting mounting rod 403, allowing several... An anti-climb ring 405 is fixedly installed between two fixed frames 402. When someone attempts to climb the protective wall panel 5, the fixed frame 402 and the limiting support block 401 are pulled downward by the climber, thereby causing the limiting support block 401 to move in the rectangular mounting groove 3 of the support column 2. At the same time, it causes the two guide sliders 409 to move downward inside the guide groove 408, and simultaneously compresses the support spring 410. The limiting support block 401 touches the micro switch 406 downward, and the micro switch 406 activates the audible and visual alarm 7 to issue an alarm reminder, thereby serving as a warning on site.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
