This facilitates recycling and centralized transportation, effectively improving the practicality and convenience of the construction site fence.

Description

Technical Field

[0001] This utility model relates to the field of construction site enclosure technology, specifically to a foldable construction site enclosure. Background Technology

[0002] Construction site fencing is an indispensable facility during the construction process. Its main function is to isolate the construction area from the external environment, creating a relatively enclosed space. This ensures the construction area remains relatively independent and undisturbed by external factors, while also preventing building materials from splashing and protecting the safety of surrounding personnel and the environment.

[0003] Most common construction site fencing uses prefabricated panels welded to supporting columns, which are then fixed to the ground with screws and other fasteners. However, this traditional fencing has drawbacks. After construction is completed and dismantled, its large size and irregular shape make it inconvenient to transport and relocate to other construction sites for reuse, increasing construction costs and wasting resources. Therefore, we provide a foldable construction site fencing solution. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable construction fence to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A foldable construction fence includes a fence with a top plate, a base at the bottom of the top plate, and a connecting vertical tube at the right side of the top plate and the base.

[0007] A folding unit is provided between the top plate and the base, and a connecting unit is provided on both sides of the base of the top plate.

[0008] The folding unit includes a rotating shaft one fixedly installed at the bottom of the top plate, a rotating shaft two fixedly installed at the top of the base, a folding plate rotatably connected to the inner axis of the rotating shaft two, and the other end of the folding plate rotatably connected to the inner axis of the rotating shaft one.

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.

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides a foldable construction fence, including a fence 1. The fence 1 includes a top plate 2, a base 3 at the bottom of the top plate 2, a connecting vertical tube 4 on the right side of the top plate 2 and the base 3, a folding unit between the top plate 2 and the base 3, and connecting units on both sides of the base 3 of the top plate 2. The folding unit includes a first rotating shaft 21 fixedly installed at the bottom of the top plate 2, a second rotating shaft 31 fixedly installed at the top of the base 3, a folding plate 32 rotatably connected to the inner axis of the second rotating shaft 31, and the other end of the folding plate 32 rotatably connected to the inner axis of the first rotating shaft 21. The top of the outer surface of the folding plate 32 is... A fixed sleeve 33 is fixedly fitted at the top plate 2. A limit hole 34 is opened on the right side of the fixed sleeve 33. A locking hole 35 is opened at the bottom end of the limit hole 34. A piston rod 22 is fixedly installed on the right side of the bottom end of the top plate 2. A locking block 23 is slidably fitted on the outer surface of the bottom end of the piston rod 22. A return spring 24 is fitted on the outer surface of the piston rod 22 above the locking block 23. One end of the return spring 24 is fixedly installed on the bottom end of the top plate 2, and the other end of the return spring 24 is fixedly installed on the top of the locking block 23. A locking rod 25 is fixedly installed on the bottom end of the locking block 23. The other end of the locking rod 25 is movably inserted into the inside of the locking hole 35.

[0027] Furthermore, when the enclosure 1 needs to be folded, first pinch the locking block 23 upwards, causing it to slide upwards along the piston rod 22. At this time, the return spring 24 is compressed, and the locking block 23 rises, causing the locking rod 25 to be pulled out from the locking hole 35 and the limiting hole 34, releasing the lock on the folding plate 32. Then, pull the top plate 2 to the right, and the folding plate 32 rotates around the first pivot 21 and the second pivot 31, so that the top plate 2 and the base 3 are folded to the storage angle. Under the elastic pushing force of the return spring 24, the locking block 23 causes the locking rod 25 to be inserted into the corresponding limiting hole 34 and the locking hole 35, thus completing the locking of the folding plate 32 and keeping the enclosure 1 in the unfolded state.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the connecting unit includes a first plug block 26 fixedly installed on the outer surfaces of both sides of the top plate 2, a second plug block 36 fixedly installed on the outer surfaces of both sides of the base 3, a plug groove 41 opened at the upper and lower ends of both sides of the shell of the connecting vertical cylinder 4, a semi-circular fixing block 42 fixedly installed at the top of the front and rear ends of the connecting vertical cylinder 4, a plug vertical plate 43 movably inserted into the top of the connecting vertical cylinder 4, the other end of the plug vertical plate 43 passing through the first plug block 26 and the second plug block 36 and extending to the bottom of the connecting vertical cylinder 4, and a fixing ring 44 rotatably connected to the top of the front and rear ends of the plug vertical plate 43, the fixing ring 44 being rotatably sleeved on the outer surface of the semi-circular fixing block 42.

[0030] Furthermore, if multiple fences 1 need to be connected together, the first 26 of the top plate 2 on both sides of the adjacent fence 1 and the second 36 of the base 3 on both sides are aligned with the insertion slots 41 on both sides of the connecting vertical cylinder 4 and inserted into them. Then, the insertion vertical plate 43 is inserted from the top of the connecting vertical cylinder 4, so that it passes through the first 26 and the second 36 and extends to the bottom of the inner end of the connecting vertical cylinder 4. Then, the fixing rings 44 at the top of the front and rear ends of the insertion vertical plate 43 are rotated so that they fit on the outer surface of the semi-circular fixing block 42, thereby fixing the insertion vertical plate 43 and realizing a stable connection between multiple fences.

[0031] The working principle of this foldable construction fence will be explained in detail below.

[0032] like Figure 1-5 As shown, when the enclosure 1 needs to be folded, first pinch the locking block 23 upwards, causing it to slide upwards along the piston rod 22. At this time, the return spring 24 is compressed, and the locking block 23 rises, causing the locking rod 25 to be pulled out from the locking hole 35 and the limiting hole 34, thus releasing the lock on the folding plate 32. Then, pull the top plate 2 to the right, and the folding plate 32 rotates around the first pivot 21 and the second pivot 31, so that the top plate 2 and the base 3 fold to the storage angle. Under the elastic pushing force of the return spring 24, the locking block 23 causes the locking rod 25 to be inserted into the corresponding limiting hole 34 and locking hole 35, thus completing the locking of the folding plate 32. Keep the fence 1 in the unfolded state. If multiple fences 1 need to be connected together, align the first 26 on both sides of the top plate 2 of the adjacent fence 1 and the second 36 on both sides of the base 3 with the insertion slots 41 on both sides of the connecting vertical cylinder 4 and insert them into them. Then, insert the insertion vertical plate 43 from the top of the connecting vertical cylinder 4, so that it passes through the first 26 and the second 36 and extends to the bottom of the inner end of the connecting vertical cylinder 4. Then, rotate the fixing ring 44 at the top of the front and rear ends of the insertion vertical plate 43 so that it fits on the outer surface of the semi-circular fixing block 42, thereby fixing the insertion vertical plate 43 and realizing a stable connection between multiple fences.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
