Adjustable construction enclosure

Abstract

This utility model provides an adjustable construction site fence, relating to the field of construction site fence technology, including a positioning frame. The lower front end of the positioning frame is slidably connected to the lower end of a rotating frame A, and the upper front end of the positioning frame is rotatably connected to the upper end of a rotating frame B. When the screw is rotated, the lifting block moves up and down through the engagement of the threaded hole and the screw, thereby pushing the lower end of the rotating frame A to slide along the front end of the positioning frame. Combined with the connecting shaft structure between the rotating frame A and the rotating frame B, the lower end of the rotating frame B moves up and down at the rear end of the mounting plate, ultimately achieving adjustment of the distance between the positioning frame and the mounting plate. This solves the problem that existing construction site fences are difficult to adjust flexibly according to actual needs after installation. If a change of position is required, disassembly and reinstallation are usually necessary, which is cumbersome, consumes a lot of manpower, material resources and time, and has poor convenience, failing to meet the diverse position adjustment needs of construction sites.

Description

Technical Field

[0001] This utility model belongs to the field of construction site enclosure technology, and more specifically, it relates to an adjustable construction site enclosure. Background Technology

[0002] Construction site enclosures are measures taken to isolate the construction site from the external environment, making the construction site a relatively closed space. These include walls built with various masonry materials and protective structures made of various prefabricated panels.

[0003] Application number CN202020454750.7 discloses a construction site fence, relating to the field of construction site fence technology. This utility model includes two outer frames; an inner telescopic frame is fixedly installed between the opposing surfaces of the two outer frames; an inner frame is fixedly installed in the middle of the inner telescopic frame; legs are fixedly connected to the bottom surfaces of both outer and inner frames; a set of linearly arrayed support frames are connected to the periphery of the inner telescopic frame; corrugated noise-reducing covers are fixedly connected between the support frames and the opposing surfaces of the inner and outer frames; several corrugated noise-reducing covers are interconnected at one end to form an air-filled cavity; an inflation connector is provided on the surface of one corrugated noise-reducing cover. This utility model, through the design of the inner telescopic frame and corrugated noise-reducing covers, transforms the traditional fixed-specification fence into an adjustable-specification fence. The adjustability of the fence increases its usability and versatility, and the telescopic structure design facilitates its transportation and rapid deployment.

[0004] Based on the above patent searches and understanding of the application of existing construction site hoardings: traditional construction site hoardings are difficult to adjust the front and rear positions of the hoarding panels according to actual needs after installation. If the position needs to be changed, it usually needs to be disassembled and reinstalled, which is cumbersome, consumes a lot of manpower, material resources and time, and is not convenient enough to meet the diverse position adjustment needs of construction sites. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an adjustable construction site fence. This solves the problem that existing construction site fences are difficult to adjust flexibly according to actual needs after installation. If a change in position is required, disassembly and reinstallation are usually necessary, which is cumbersome, consumes a lot of manpower, material resources and time, and is not convenient enough to meet the diverse position adjustment needs of construction sites.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An adjustable construction site enclosure includes a positioning frame; the lower front end of the positioning frame is slidably connected to the lower end of a rotating frame A, the upper front end of the positioning frame is rotatably connected to the upper end of a rotating frame B, a connecting shaft passes through the middle of the rotating frame B and the rotating frame A, the rotating frame B and the rotating frame A are rotatably connected via the connecting shaft, the upper end of the rotating frame A is rotatably connected to the upper rear end of a mounting plate, and the lower end of the rotating frame B is slidably connected to the lower rear end of the mounting plate, the rotating frame B and the rotating frame A together form an X-shaped structure.

[0008] According to one embodiment of the present invention, a lifting block is rotatably connected to the lower middle position of the rotating frame A, and a through threaded hole is provided in the middle position of the lifting block.

[0009] According to one embodiment of the present invention, a screw is rotatably connected to the middle position of the front end of the positioning frame, and the screw passes through the threaded hole of the lifting block.

[0010] According to one embodiment of the present invention, an mounting component is fixedly installed on the lower left and right sides of the inside of the positioning frame. The two mounting components are symmetrically designed, and each mounting component has a through hole at the lower inner side.

[0011] According to one embodiment of the present invention, the positioning frame is located at the front of the mounting plate, and a through hole is provided at each of the four corners of the front end of the mounting plate.

[0012] According to one embodiment of the present invention, the front end of the mounting plate is attached to the rear end of the enclosure panel, and perforations are provided at all four corners of the enclosure panel. The four perforations of the mounting plate correspond to the four perforation positions of the enclosure panel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The positioning frame can be quickly fixed to the ground using expansion bolts or ground nails through the mounting parts and through holes below it, ensuring the overall stability of the fence and providing a reliable foundation for the subsequent installation of the fence panels.

[0015] When the screw is rotated, the lifting block moves up and down through the engagement of the threaded hole and the screw, thereby pushing the lower end of the rotating frame A to slide along the front end of the positioning frame. Combined with the connecting shaft structure between the rotating frame A and the rotating frame B, the lower end of the rotating frame B moves up and down at the rear end of the mounting plate, ultimately achieving the adjustment of the distance between the positioning frame and the mounting plate. This design eliminates the need to disassemble the enclosure and allows for flexible adjustment of the front and rear positions of the enclosure by rotating the screw, avoiding the cumbersome operation of traditional disassembly and reassembly, significantly improving construction convenience, and saving manpower, time, and costs.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides an adjustable construction site enclosure, including a positioning frame 1; the lower front end of the positioning frame 1 is slidably connected to the lower end of a rotating frame A104, and the upper front end of the positioning frame 1 is rotatably connected to the upper end of a rotating frame B105. A connecting shaft 106 passes through the middle of the rotating frame B105 and the rotating frame A104, and the rotating frame B105 and the rotating frame A104 are rotatably connected through the connecting shaft 106. The upper end of the rotating frame A104 is rotatably connected to the upper rear end of a mounting plate 107, and the lower end of the rotating frame B105 is slidably connected to the lower rear end of the mounting plate 107. The rotating frame B105 and the rotating frame A104 together form an X-shaped structure.

[0028] Among them, a lifting block 102 is rotatably connected to the lower middle position of the rotating frame A104. A through threaded hole is opened in the middle position of the lifting block 102. A screw 103 is rotatably connected to the front middle position of the positioning frame 1. The screw 103 passes through the threaded hole of the lifting block 102. An installation component 101 is fixedly installed on the lower left and right sides of the interior of the positioning frame 1. The two installation components 101 are symmetrically designed, and a through hole is opened in the lower inner position of both installation components 101.

[0029] The positioning frame 1 is located directly in front of the mounting plate 107, and a through hole is opened at each of the four corners of the front end of the mounting plate 107. The front end of the mounting plate 107 is attached to the rear end of the enclosure plate 2, and a through hole is opened at each of the four corners of the enclosure plate 2. The four through holes of the mounting plate 107 correspond to the four through hole positions of the enclosure plate 2.

[0030] When using:

[0031] Place the positioning frame 1 at the location where the construction site needs to be fenced off. Fix the positioning frame 1 to the ground using expansion bolts or ground nails through the through hole of the mounting part 101 to ensure that it is stable and does not shake.

[0032] The fencing panel 2 is attached to the front end of the mounting plate 107, so that the perforations at the four corners of the fencing panel 2 correspond one-to-one with the four perforations of the mounting plate 107. The fencing panel 2 is then fixed by bolts and nuts, thus completing the connection between the fencing panel 2 and the mounting plate 107. The installation is convenient and facilitates the subsequent side-by-side installation of multiple fencing panels 2.

[0033] After rotating the screw 103, the lifting block 102 engages with the screw 103 through a threaded hole. The rotation of the screw 103 is converted into the up-and-down movement of the lifting block 102. The lifting block 102 is rotatably connected to the lower middle position of the rotating frame A104. Therefore, the movement of the lifting block 102 will push the lower end of the rotating frame A104 to slide and adjust along the lower position of the front end of the positioning frame 1. Combined with the connecting shaft 106 set between the rotating frame A104 and the rotating frame B105, the lower position of the rotating frame B105 moves up and down at the lower rear end position of the mounting plate 107, thereby adjusting the distance between the positioning frame 1 and the mounting plate 107. This allows the distance between the front and rear positions of the enclosure plate 2 to be adjusted after installation, avoiding the traditional disassembly and reinstallation, thus achieving a convenient effect.

[0034] Although this application has been described with reference to the foregoing embodiments, those skilled in the art will understand that various changes can be made without departing from the spirit and scope of this application as defined by the appended claims. While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments. The scope of this application is defined by the appended claims and their equivalents, and is not limited to the embodiments described above.
