Description

Technical Field

[0002] Security fences are facilities used to define, limit or protect a specific area, designed to prevent people or objects from entering or leaving the area to ensure safety. Security fences can be used in a variety of places and occasions, including industrial sites, construction sites, public places, residential areas, etc., and their design and use will vary according to specific needs and environments.

[0003] For example, a Chinese utility model patent (CN220395369U) discloses an efficient construction project safety fence, which records: "It can facilitate the rapid and efficient installation and use of multiple construction project safety fences, improve the installation and use efficiency of multiple construction project safety fences, facilitate the recovery and reuse of construction project safety fences, and avoid the situation where the construction project safety fences cannot be reasonably reused later." It also records: "Traditional multiple construction project safety fences are mostly fixed by multiple bolts or welding when installed and connected together. The multiple bolt fixing connection method has a complex structure, which is not conducive to the rapid and efficient installation and use of multiple construction project safety fences, resulting in low installation and use efficiency between multiple construction project safety fences. The welding method will not be convenient for the recovery and reuse of the construction project safety fences, resulting in the inability to reasonably reuse the construction project safety fences later." Technical problems.

[0004] In summary, it can be seen that the prior art utilizes fastening arc blocks and fastening holes to enable two safety fences to be quickly and detachably installed. However, this method has the following technical problems: However, during transportation, the height of the device cannot be changed, which makes it occupy a large space during transportation, thereby increasing transportation costs. For this reason, the present application proposes a safety fence to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] As in the background art, however, the height of the device cannot be changed during transportation, so it occupies a large space during transportation, which leads to an increase in transportation costs.

[0030] In order to solve this technical problem, the utility model provides a safety fence, which is applied to a safety fence for construction projects with adjustable height.

[0031] Specifically, please refer to Figure 1-Figure 4 , the safety fence specifically includes:

[0032] It includes a fence base 1, an adjusting mechanism 3 is respectively arranged at the top of the fence base 1 and near the edges of both ends, a protecting mechanism 2 is arranged at the top of the fence base 1, a receiving plate 4 is arranged at the top of the protecting mechanism 2, the receiving plate 4 is arranged at the top of the adjusting mechanism 3, and a spraying mechanism 5 is arranged at the top of the receiving plate 4;

[0033] The adjustment mechanism 3 includes a support shell 11, a rotating rod 12, a handle 13, a height adjustment component, a limiting component, and a connecting component. The inner wall of the support shell 11 is rotatably connected to the rotating rod 12, and one end of the rotating rod 12 located outside the support shell 11 is fixedly connected to the handle 13.

[0034] The safety fence provided by the utility model can make the limiting rod 25 leave the limiting hole 22 by pulling the limiting block 26, so that the rotating rod 12 can rotate freely, and the handle 13 can be turned to drive the driving gear 14 to rotate through the rotating rod 12, so that the racks 15 on both sides thereof can move upward or downward respectively, so that the overall height of the fence can be adjusted. After the adjustment, the limiting block 26 is released to allow the limiting rod 25 to enter the limiting hole 22 to limit the rotation of the rotating rod 12, so that the height of the device remains stable, thereby improving the stability of the device. The height adjustment allows the height of the fence to be reduced to a minimum during transportation, thereby reducing the space occupied by the transportation of a single fence and reducing the transportation cost.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] Embodiment 1:

[0037] Please refer to Figure 2-Figure 5 , a safety fence, comprising:

[0038] The height adjustment assembly includes a driving gear 14 fixedly connected to the outer wall of the rotating rod 12 and located inside the supporting shell 11, and racks 15 are respectively meshed on both sides of the driving gear 14, and fixed rails 16 are respectively fixedly connected to both sides of the inner wall of the supporting shell 11, and the racks 15 are slidably connected to the inner walls of the fixed rails 16. One end of the two racks 15 located outside the supporting shell 11 is respectively fixedly connected to top plates 17. Since the two racks 15 are on both sides of the driving gear 14, when the driving gear 14 rotates, the two racks 15 move in directions away from or close to each other. The top of the upper top plate 17 is fixedly connected to the bottom of the receiving plate 4, and the bottom of the lower top plate 17 is fixedly connected to the top of the fence base 1.

[0039] The limiting assembly includes a limiting disk 21 fixedly connected to the outer wall of the rotating rod 12, and a plurality of limiting holes 22 are opened on the outer wall of the limiting disk 21. Two fixed plates 23 are fixedly connected to the inner wall of the supporting shell 11, and a limiting rod 25 is slidably connected to the inner wall of the supporting shell 11. One end of the limiting rod 25 close to the limiting disk 21 is adapted to the limiting hole 22, and the outer wall of the limiting rod 25 is fixedly connected to a sliding plate 24. Both sides of the sliding plate 24 are respectively slidably connected to the sides where the two fixed plates 23 are close to each other. One end of the limiting rod 25 away from the limiting disk 21 is fixedly connected to a limiting block 26, and one end of the limiting rod 25 away from the limiting block 26 is clamped in the limiting hole 22. The outer wall of the sliding plate 24 is fixedly connected to a spring 27, and the spring 27 is always in a compressed state during the operation of the device. One end of the spring 27 away from the sliding plate 24 is fixedly connected to the inner wall of the supporting shell 11.

[0040] The connecting assembly includes a connecting frame 19 and a connecting plate 20. The connecting frame 19 and the connecting plate 20 are respectively provided with holes for inserting the plug rod 18. The connecting plate 20 and the connecting frame 19 are respectively fixedly connected to the sides of the left and right support shells 11 that are away from each other. The connecting plate 20 is adapted to the connecting frame 19. A top plate 17 on the upper right side is fixedly connected to the side of the plug rod 18 that is away from the protective mechanism 2. The outer walls of the plug rod 18 are respectively movable on the inner walls of the connecting frame 19 and the connecting plate 20. In a device that relies on the connecting frame 19 to be assembled with another device, when it is in use, its height cannot be arbitrarily adjusted to the point where the plug rod 18 on the device is separated from the connecting frame 19 and the connecting plate 20 of the other device to avoid separation between the two devices.

[0041] Through the above structural design, the limiting block 26 is pulled, thereby driving the limiting rod 25 to leave the limiting hole 22. In this process, the limiting rod 25 will drive the sliding plate 24 to slide on the fixed plate 23, and the spring 27 will be further compressed. The handle 13 can be turned to drive the driving gear 14 to rotate through the rotating rod 12, thereby driving the racks 15 on both sides of the driving gear 14 to move to the sides or the middle. In the process of the two racks 15 moving to the sides, the distance between the receiving plate 4 and the fence base 1 is increased, thereby increasing the overall height of the device to a suitable level. When the device needs to be folded, When the two racks 15 are controlled to move to the middle position, the distance between the receiving plate 4 and the fence base 1 is shortened to facilitate the folding of the device. When two adjacent devices are spliced, the connecting frame 19 of one device and the connecting plate 20 of the other device are placed opposite to each other, and the height of the device spliced ​​by the connecting frame 19 is raised to the highest, so that the insertion rod 18 leaves the connecting frame 19, and the connecting plate 20 is inserted into the connecting frame 19, and then the height of the device installed by the connecting frame 19 is adjusted, so that the insertion rod 18 is inserted into the connecting frame 19 and the connecting plate 20, thereby completing the splicing between the devices.

[0042] Embodiment 2:

[0043] The safety fence provided in Example 1 is further optimized, specifically, as follows: Figure 2 As shown, the protection mechanism 2 includes a plurality of fixed shells 6 fixedly connected to the top of the fence base 1, the inner walls of the plurality of fixed shells 6 are respectively slidably connected with sliding columns 7, and the tops of the plurality of sliding columns 7 are respectively fixedly connected to the bottom of the receiving plate 4. In the application of the device, the specific number of protection mechanisms 2 can be set as needed to facilitate practical applications in different scenarios, ensuring that the cost of a single device is reduced while meeting the requirements of use.

[0044] Through the above structural design, when the overall height of the device is adjusted, the distance between the receiving plate 4 and the fence base 1 changes accordingly, so that the sliding column 7 slides inside the fixed sleeve 6 to adapt to the height change of the device.

[0045] Embodiment 3:

[0046] The safety fence provided in Example 1 is further optimized, specifically, as follows: Figure 2 As shown, the spraying mechanism 5 includes a water pipe 8 fixedly connected to the top of the receiving plate 4, a plurality of nozzles 9 are fixedly connected to the inner wall of the water pipe 8, a water inlet pipe 10 is fixedly connected to the inner wall of the water pipe 8, and a joint for connecting to a water supply pipe is provided at one end of the water inlet pipe 10 away from the water pipe 8 to facilitate water flow when dust reduction is required.

[0047] Through the above-mentioned structural design, when it is necessary to reduce dust on the construction site, water is passed from the water inlet pipe 10 to the inside of the water pipe 8, and then water mist is sprayed through multiple nozzles 9 to reduce dust on the site. Moreover, as the height of the receiving plate 4 changes, the range of dust reduction on the site changes accordingly.
