Description

Technical Field

[0001] This utility model relates to the field of construction fence technology, and in particular to a construction fence for environmental protection projects. Background Technology

[0002] As we all know, environmental engineering is a comprehensive engineering discipline that aims to protect and improve environmental quality using engineering techniques and scientific methods. During the construction of environmental engineering projects, numerous hazardous factors often exist at the construction site. For example, at the construction site of sewage treatment facilities, there may be deep pits being excavated, underground pipelines being laid, or large sewage treatment equipment being installed. Construction fences are typically used to isolate these hazardous areas from the outside world, preventing unauthorized personnel, such as passersby or nearby residents, from accidentally entering the construction site and thus avoiding potential accidents such as falls, collisions, or injuries from construction machinery.

[0003] However, traditional construction fences for environmental protection projects usually require welding or bolting multiple horizontal bars, which is a cumbersome installation process and can easily lead to slow construction progress. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a construction fence for environmental protection projects. When using this construction fence, simply pulling the locking block will rotate the rotating rod, thereby pulling out multiple warning reflective strips. By cooperating with another set of main rods, pulling the locking blocks one by one compresses the internal return springs, at which point the locking blocks engage with the locking slots. Releasing the locking blocks then causes the slider to engage with the positioning slot, thus limiting the movement of the warning reflective strips. The warning reflective strips can be quickly deployed or retracted, making the installation and dismantling of the fence faster and saving time and labor costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An environmental protection construction fence includes multiple main poles. Multiple mounting boxes are fixedly connected to the outer wall of the rear end of each main pole. The outer wall of the rear end of each mounting box has a snap-fit ​​groove. A slider is slidably connected to one side of the inner wall of the snap-fit ​​groove. Movable grooves are provided on one side of the top and bottom surfaces of the snap-fit ​​groove. A return spring is fixedly connected to one side of the inner wall of each movable groove. The outer wall of the other side of the return spring is fixedly connected to the outer wall of the slider.

[0007] The main body has multiple storage cavities from top to bottom. A rotating rod is rotatably connected to the middle of the bottom surface of each storage cavity at the lower end. Multiple warning reflective strips are fitted on the outer wall of each rotating rod. The lower ends of each warning reflective strip are attached to the bottom surface of the storage cavity. The front ends of each warning reflective strip penetrate the main body to the outside of the main body and are fixedly connected to a snap-fit ​​block.

[0008] The inner wall of each storage cavity is embedded with multiple limiting boxes. Each limiting box has a storage slot on its outer wall adjacent to another storage slot. Each storage slot has a multiple limiting spring fixedly connected to its inner wall adjacent to another storage slot. Each limiting spring has a mounting bracket fixedly connected to its adjacent side. Each mounting bracket has a stop wheel rotatably connected to its bottom and top surfaces. Each stop wheel's outer wall adjacent to another stop wheel is tightly fitted to the outer wall of the warning reflective strip.

[0009] Compared with existing construction fences for environmental protection projects, the construction fence for environmental protection projects described above has a higher overall volume as it is continuously pulled. This is because the limit spring slowly releases its force, causing the roller to continuously approach the warning reflective strip. This ensures that the fence remains smooth and easy to pull out and retract, preventing it from getting tangled and causing obstruction. As a result, the fence has higher practical performance.

[0010] Furthermore, one side of each slider passes through the snap-fit ​​groove and the mounting box and is fixedly connected with a pull block;

[0011] The above technical solution allows the slider to be moved by pulling the block.

[0012] Furthermore, a groove is formed on the outer wall of the rear end of the pull block;

[0013] The above technical solution facilitates the pulling of the block by using a groove.

[0014] Furthermore, the upper end of each rotating rod extends through multiple storage cavities to the outside of the main rod and is fixedly connected with a knob;

[0015] The above technical solution allows the knob to easily drive the rotating rod to rotate.

[0016] Furthermore, each of the snap-fit ​​blocks engages with a snap-fit ​​slot.

[0017] The above technical solution facilitates the positioning of the snap-fit ​​blocks by having each snap-fit ​​block engage with the snap-fit ​​slot.

[0018] Furthermore, each of the snap-fit ​​blocks has a positioning groove on its other side, and each positioning groove is engaged with the slider.

[0019] With the above technical solution, the positioning grooves are respectively engaged with the slider, which facilitates the limiting of the locking block.

[0020] Furthermore, the top and bottom surfaces of the limiting box are provided with limiting grooves, and the upper and lower surfaces of the mounting bracket are fixedly connected with limiting blocks, and the limiting blocks are slidably connected to the inner walls of the limiting grooves respectively.

[0021] With the above technical solution, the limiting blocks are slidably connected to the inner wall of the limiting groove, which facilitates the limiting of the abutment wheel while preventing the limiting spring from twisting.

[0022] Furthermore, each of the main body rods is fixedly connected to a support base at its lower end;

[0023] The above technical solution, through the support base, facilitates the improvement of overall stability.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes an environmental protection construction fence. Compared with existing environmental protection construction fences, this fence only requires pulling the locking block to rotate the rotating rod, thereby pulling out multiple warning reflective strips. By cooperating with another set of main rods, the locking blocks are pulled one by one to compress the internal return springs. At this time, the locking blocks are engaged with the locking grooves. Then, the locking blocks are released, which causes the slider to engage with the positioning grooves. This can limit the movement of the warning reflective strips and allow them to be quickly unfolded or retracted, making the installation and dismantling of the fence faster and saving time and labor costs.

[0026] 2. The construction fence for environmental protection projects proposed in this utility model, compared with the existing construction fences for environmental protection projects, has a larger overall volume as the warning fence is continuously pulled. At this time, the limit spring slowly releases its force, which drives the roller to continuously approach the warning reflective strip. This ensures that the fence remains smooth and easy to pull out and retract, and prevents the fence from getting tangled and causing obstruction. It has high practical performance.

[0038] 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.

[0039] Reference Figure 1-9 An embodiment of this utility model is provided: a construction fence for environmental protection engineering, including multiple main poles 1, multiple mounting boxes 11 are fixedly connected to the outer wall of the rear end of each main pole 1, a snap-fit ​​groove 14 is opened on the outer wall of the rear end of each mounting box 11, a slider 15 is slidably connected to one side of the inner wall of the snap-fit ​​groove 14, a movable groove 16 is opened on one side of the top and bottom surfaces of the snap-fit ​​groove 14, a return spring 17 is fixedly connected to one side of the inner wall of each movable groove 16, and the outer wall of the other side of the return spring 17 is fixedly connected to the outer wall of the slider 15 respectively.

[0040] The main body rod 1 has multiple storage cavities 2 from top to bottom. The bottom of the lower storage cavity 2 is rotatably connected to a rotating rod 21. The outer wall of the rotating rod 21 is fitted with multiple warning reflective strips 23. The lower end of each warning reflective strip 23 is in contact with the bottom surface of the storage cavity 2. The front end of each warning reflective strip 23 passes through the main body rod 1 to the outside of the main body rod 1 and is fixedly connected to a snap-fit ​​block 24.

[0041] Multiple limiting boxes 3 are embedded in the inner wall of the storage cavity 2. Storage slots 31 are opened on the outer wall of the adjacent side of the limiting box 3. Multiple limiting springs 32 are fixedly connected to the inner wall of the adjacent side of the storage slot 31. Mounting brackets 33 are fixedly connected to the adjacent side of the limiting springs 32. Abutment wheels 34 are rotatably connected to the bottom and top surfaces of the mounting brackets 33. The outer wall of the adjacent side of the abutment wheel 34 is tightly attached to the outer wall of the warning reflective strip 23.

[0042] Compared with existing construction fences for environmental protection projects, this construction fence for environmental protection projects has a smaller overall volume as the warning fence is continuously pulled. At this time, the limit spring 32 slowly releases its force, causing the roller to continuously approach the warning reflective strip 23. This ensures that the fence remains smooth and easy to pull out and retract, preventing them from getting tangled and causing obstruction. It has high practical performance.

[0043] Each slider 15 has a pull block 12 fixedly connected to a snap-fit ​​groove 14 and mounting box 11 on one side. The pull block 12 facilitates the movement of the slider 15. A pull groove 13 is provided on the outer wall of the rear end of the pull block 12, which facilitates the pulling of the pull block 12. The upper end of each rotating rod 21 passes through multiple storage cavities 2 to the outside of the main rod 1 and is fixedly connected to a knob 22. The knob 22 facilitates the rotation of the rotating rod 21. Each snap-fit ​​block 24 engages with the snap-fit ​​groove 14, which facilitates the positioning of the snap-fit ​​block 24. Each snap-fit ​​block 24 has a positioning groove on the other side. The slot 25 and the positioning slot 25 are respectively engaged with the slider 15. The engagement of the positioning slot 25 with the slider 15 facilitates the limiting of the locking block 24. The top and bottom surfaces of the limiting box 3 are provided with limiting slots 35. The upper and lower surfaces of the mounting bracket 33 are fixedly connected with limiting blocks 36. The limiting blocks 36 are slidably connected to the inner wall of the limiting slot 35. The slidable connection of the limiting blocks 36 to the inner wall of the limiting slot 35 facilitates the limiting of the abutment wheel 34 while preventing the limiting spring 32 from twisting. The lower end of the main rod 1 is fixedly connected with a support seat 4, which helps to improve the overall stability.

[0044] Working principle: When in use, pulling the locking block 24 will drive the rotating rod 21 to rotate, thereby pulling out multiple warning reflective strips 23. By cooperating with another set of main rods 1, the pulling blocks 12 are pulled one by one to compress the internal return spring 17. At this time, the locking block 24 is engaged with the locking groove 14. Then, the pulling block 12 is released, thereby driving the slider 15 to engage with the positioning groove 25, which can limit the warning reflective strips 23. The warning reflective strips 23 can be quickly unfolded or retracted. When it is necessary to retract, the knob 22 needs to be turned in conjunction with the abutment wheel 34 to retract it.

[0045] 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.
