Description

Technical Field

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

[0002] Construction site fences are external enclosures and barriers used at construction sites to isolate the construction site.

[0003] Common construction site fencing uses screws and connectors to connect the panels. To ensure the stability of the connection between the panels, multiple sets of screws and connectors are needed. Once the panels are fixed, it is inconvenient to change their usage or adjust their position. This results in construction site fencing composed of multiple panels having poor adaptability to different application scenarios. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a construction site fence, which has the advantages of being flexible and convenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction site fence, comprising a main column, characterized in that a hexagonal prism is rotatably connected to both sides of the main column, a fence frame is connected to the hexagonal prism via connecting ears, a vertically extending cavity is provided inside the main column, a first screw is rotatably connected inside the cavity, a vertically extending first guide groove is provided on the left and right sides of the main column, a vertically extending second guide groove is provided on the front side of the main column, and a lifting assembly is threadedly connected to the first screw;

[0006] The main column is provided with a limit cover on the upper side, and a limit cylinder matching the cavity is provided on the lower side of the limit cover. The limit cover on both sides of the limit cylinder is provided with insertion holes corresponding to the hexagonal prism. The top end of the first screw 4 passes through the limit cylinder and the limit cover.

[0007] The lifting assembly includes a lifting ring threadedly connected to a first screw. Connecting blocks are provided on both sides of the lifting ring. One side of the connecting block passes through the first guide groove and is connected to a support ring. The hexagonal prisms on both sides pass through the support rings on the corresponding sides. A second screw corresponding to the second guide groove is provided on the front side of the lifting ring. The second screw is threadedly connected to a fastening nut. The hexagonal prisms pass through connecting ears, and each support ring corresponds to a lifting ear, which is located above the support ring.

[0008] In the above solution, two connecting ears are provided on each side of the enclosure frame, and there are also two lifting components. This increases the reliability of the connection.

[0009] In the above solution, a rotating handle is provided at the top of the first screw, and there is a gap between the rotating handle and the top of the limiting cover. This gap is sufficient to allow the top of the hexagonal prism to disengage from the insertion hole of the limiting cover when the limiting cover is lifted upwards. This facilitates the use of the limiting cover.

[0010] In the above design, a rotating handle is provided at the top of the first screw to facilitate rotation of the first screw.

[0011] In the above design, the inner diameter of the support ring is larger than the maximum diameter of the hexagonal prism, facilitating the movement of the support ring.

[0012] In the above scheme, a warning light is provided on the upper part of the first screw.

[0013] In the above design, a handle is provided on the upper side of the hexagonal prism to facilitate rotation of the prism.

[0014] The construction site fence provided by this utility model has the following beneficial effects: by setting rotatable hexagonal prisms on both sides of the main column, the top cover can be lifted during use, and the angle of the hexagonal prisms and the fence frame can be quickly adjusted by using the handle, so that the fence frame can be adapted to different application scenarios. At the same time, a first screw is set inside the main column, which can be used in conjunction with the lifting component to drive the fence frame to adjust its height, further increasing the practicality of the fence.

[0024] Example

[0025] Please see Figure 1-7 A construction site fence includes a main column 1, with hexagonal prisms 2 rotatably connected to both sides of the main column 1, and a fence frame 3 connected to the hexagonal prisms 2.

[0026] The main column 1 includes a base plate and a main column body. Four fixing nails are provided at the four corners of the base plate to facilitate fixing the column to the ground. The left and right sides of the bottom of the main column body extend outward to form extensions for mounting hexagonal prisms. The extensions are provided with mounting holes corresponding to the hexagonal prisms 2, and the bottom of the hexagonal prisms 2 are rotatably connected to these mounting holes.

[0027] The enclosure frame 3 mainly consists of a frame body and connecting lugs. The frame body includes two vertical columns on both sides and horizontal bars running from top to bottom between the vertical columns. The connecting lugs are connected to the vertical columns on both sides of the frame body by screws. Each of the two vertical columns has two symmetrically arranged connecting lugs, and the connecting lugs are provided with connecting holes through which the hexagonal prism 2 passes.

[0028] The main column 1 has a vertically extending cavity inside, and a first screw 4 is rotatably connected inside the cavity. The main column 1 has vertically extending first guide grooves on the left and right sides, and a vertically extending second guide groove on the front side. The first screw 4 is threadedly connected to a lifting assembly.

[0029] A limiting cover 5 is installed on the upper side of the main column 1. The limiting cover 5 consists of a top plate and side plates located on the front and rear sides. A limiting cylinder 6 matching the cavity is installed in the middle of the lower side of the limiting cover 5. The limiting cylinder 6 can extend into the cavity. The top of the first screw 4 passes through the limiting cylinder 6 and the limiting cover 5. A warning light 7 is installed at the top of the first screw 4. The limiting cover 5 on both sides of the limiting cylinder 6 has insertion holes corresponding to the hexagonal prism 2. The top of the hexagonal prism 2 can be inserted into the insertion hole of the limiting cover 5. A handle 8 is installed on the upper part of the hexagonal prism 2. A lifting ring 14 is installed on the rear side of the limiting cover 5 to facilitate the operator to move the limiting cover 5.

[0030] Preferably, a rotating handle 15 is provided at the top of the first screw 4. A warning light 7 is located above the rotating handle 15. The rotating handle 15 facilitates the operator's rotation of the first screw 4, while the warning light 7 provides a visual warning to surrounding personnel, preventing them from entering the construction site. It should be noted that... Figure 7 As shown, there is a gap between the rotating handle 15 and the top of the limiting cover 5, and this gap is sufficient to allow the top of the hexagonal prism 2 to disengage from the insertion hole of the limiting cover 5 when the limiting cover 5 is lifted upwards.

[0031] The lifting assembly includes a lifting ring 9 threadedly connected to the first screw 4. Connecting blocks 10 are provided on both sides of the lifting ring 9. One side of each connecting block 10 passes through a first guide groove and is connected to a support ring 11. Hexagonal prisms 2 on both sides pass through the support rings 11. A second screw 12, corresponding to a second guide groove, is provided on the front side of the lifting ring 9. A fastening nut 13 is threadedly connected to the second screw 12. The second screw 12 passes through the second guide groove and is locked by the fastening nut 13. The inner diameter of the support ring 11 is larger than the maximum diameter of the hexagonal prism 2. The support ring 11 can move vertically along the hexagonal prism 2. Specifically, there are two lifting assemblies. The support rings 11 of the two lifting assemblies each correspond to a connecting lug, and the connecting lug is located above the corresponding support ring. The connecting lug is always located on the hexagonal prism and is fixed to the enclosure frame 3 with bolts during installation.

[0032] In use, the operator can separate the limiting cover 5 from the main column 1 and separate the insertion hole from the hexagonal prism 2. At this time, the operator can rotate the hexagonal prism 2 through the handle 8 and drive the enclosure frame 3 to adjust the angle. After the angle of the enclosure frame 3 is adjusted, the operator can reconnect the limiting cover 5 to the main column 1 and re-insert the insertion hole into the hexagonal prism 2. The insertion hole is a hexagonal hole, which can fix the hexagonal prism 2 after the angle is adjusted. Then, the limiting cover 5 is connected to the main column 1 with screws, so that the hexagonal prism 2 can be fixed. Thus, the enclosure frame 3 can be used for different application scenarios.

[0033] Meanwhile, the operator can rotate the first screw 4 by rotating the handle 15, which can drive the lifting ring 9 to move vertically. The lifting ring 9 will cooperate with the connecting block 10 and the supporting ring 11 to drive the height adjustment of the enclosure frame 3. The first guide groove is used to limit the position of the lifting ring 9 and the connecting block 10, while the second screw 12 will move along the second guide groove. After the height adjustment of the enclosure frame 3 is completed, the second screw 12 can cooperate with the fastening nut 13 to limit the position of the lifting ring 9, preventing the position of the lifting ring 9 from becoming loose over time.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
