Description

Technical Field

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

[0002] Construction site fencing serves as a barrier around urban construction sites, primarily functioning to provide safety protection (isolating the construction area from the outside world to prevent unauthorized personnel from entering and avoid accidents), environmental protection (reducing pollution from dust, noise, and construction waste generated during construction), beautification (harmonizing the construction site with its surroundings through uniform and aesthetically pleasing fencing), and signage and warnings. Chinese patent document CN222686358U discloses a safety construction site fencing that is easy to assemble. By incorporating an assembly mechanism, two fencing sections can be quickly assembled without tools, saving time and effort. A fixing mechanism secures the assembly, preventing it from disintegrating under external forces. Finally, an adjustment mechanism allows for real-time adjustment of the angle between the assembled fencing sections according to different construction sites, greatly improving the device's practicality. However, this construction site fencing has a fixed height and cannot be effectively adjusted. During transportation or storage when not in use, it occupies excessive space, leading to wasted space and reducing its actual usability. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a construction site fence that can be height-adjusted. When not in use, the fence can be lowered for easy transportation and storage, and when in use, it can be raised to effectively shield the construction site, thus fulfilling the functions of safety protection, environmental protection, and beautification.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A construction site enclosure includes a lower enclosure and an upper enclosure. The top surface of the lower enclosure and the bottom surface of the upper enclosure are rotatably connected by hinges. Positioning feet are fixedly installed on both sides of the bottom surface of the lower enclosure. A sliding groove is opened in the middle of the lower enclosure between the hinges, and a sliding bracket is installed in the groove. The sliding bracket consists of two vertical rods and two horizontal rods. The two vertical rods are arranged in parallel, and two parallel horizontal rods are set in the middle between them. The sides of the two vertical rods that are far apart from each other are slidably connected to the corresponding side walls of the groove. A slot is opened at the bottom of the upper enclosure corresponding to the groove, and the slot is connected to the groove. Positioning holes are opened in the middle of the two horizontal rods, and positioning components are set at the top of the slot of the upper enclosure and the groove of the lower enclosure corresponding to the positioning holes of the upper and lower horizontal rods (after the lower and upper enclosures are unfolded). Connecting ears are set in the middle of the two sides of the back of the upper enclosure and the middle of the two sides of the back of the lower enclosure, and the two connecting ears of the upper enclosure and the two connecting ears of the lower enclosure are staggered.

[0006] Based on further optimization of the above scheme, a warning bar is set on the front of the upper enclosure located above the corresponding positioning component and the lower enclosure located below the corresponding positioning component.

[0007] Based on further optimization of the above scheme, the positioning support includes a connecting block and a positioning plate. One end of the connecting block is fixedly connected to the bottom surface of the lower enclosure, and the other end is fixedly provided with the positioning plate. Bolt holes are respectively opened on both sides of the corresponding connecting block.

[0008] Based on further optimization of the above scheme, the positioning component includes a positioning pin, a pulling block and a return spring. The upper and lower enclosures are respectively provided with through holes in the positioning component, and the through holes correspond to the positioning holes of the upper and lower crossbars (after the lower and upper enclosures are unfolded). The positioning pin is slidably set in the through hole, and a pulling block is set at the end of the positioning pin away from the sliding bracket (i.e., located on the front of the enclosure). A return spring is set between the pulling block and the corresponding enclosure, and the return spring is located on the outer ring of the positioning pin.

[0009] Based on further optimization of the above scheme, annular support seats are provided on the front of the upper and lower enclosures and on the outer ring of the corresponding through holes. The positioning pin passes through the middle of the annular support seat and is slidably connected. The reset spring is provided on the outer ring of the annular support seat, and the pulling block contacts the side of the annular support seat away from the enclosure.

[0010] Based on the further optimization of the above scheme, the lower enclosure is provided with transition grooves on both sides of the slide groove, and telescopic rod assemblies are rotatably installed in the transition grooves for further support and fixation of the enclosure.

[0011] The following are the technical effects of this utility model:

[0012] This utility model utilizes a rotating connection between the upper and lower fencing sections. The height of the fencing is adjusted by folding and unfolding the upper and lower sections. When not in use, the folded sections facilitate storage and transportation; when in use, the unfolded sections effectively shield the construction site. Simultaneously, the sliding brackets of two vertical and two horizontal bars, along with the positioning components, provide effective support for the unfolded upper fencing, preventing it from needing to be refolded due to wind or other environmental factors. The operation is convenient and allows for quick unfolding, positioning, and folding of the upper and lower sections. Furthermore, the connecting lugs facilitate assembly between the two sections, saving time and effort, and also secure the upper and lower sections after folding, preventing them from disassembling during storage or transportation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1:

[0021] A construction site enclosure includes a lower enclosure 10 and an upper enclosure 20, wherein the top surface of the lower enclosure 10 and the bottom surface of the upper enclosure 20 are rotatably connected by a hinge 101 (e.g., Figure 1 As shown, in this embodiment, two hinges 101 are provided between the upper enclosure 20 and the lower enclosure 10, respectively located on the top two sides of the lower enclosure 10; the number of hinges 101 can be set according to the actual situation, but it must be ensured that the number of hinges 101 is even; the hinges 101 can adopt conventional structures in the field, such as the hinges between a household door and the door frame, or existing products in other fields can be used, which can be understood by those skilled in the art); positioning feet are fixedly provided on both sides of the bottom surface of the lower enclosure 10, and the positioning feet include connecting blocks 131 and positioning plates 132. One end of the connecting block 131 is fixedly connected to the bottom surface of the lower enclosure 10, and the other end is fixedly provided with the positioning plate 132. Bolt holes are opened on both sides of the corresponding connecting block 131 (the enclosure is fixed on the construction ground by the positioning bolts passing through the bolt holes). A sliding groove 11 is provided in the middle of the lower enclosure 10 between the hinges 101, and a sliding bracket is provided in the sliding groove 11. The sliding bracket consists of two vertical rods 32 and two horizontal rods 31 (e.g. Figure 1 As shown), two vertical bars 32 are arranged in parallel, and two parallel horizontal bars 31 are arranged in the middle between them (there is a certain distance between the two horizontal bars 31, so as to ensure that when unfolded, the two horizontal bars 31 are located at the upper enclosure 20 and the lower enclosure 10 respectively, as shown). Figure 1 As shown), the two vertical rods 32 are slidably connected to the corresponding side walls of the slide groove 11 on opposite sides (for example, a protruding slider is provided at the bottom of the opposite side wall of the two vertical rods 32, and vertical grooves are opened on the inner walls of the slide groove 11 on both sides, so that the slider is slidably engaged in the corresponding vertical groove to prevent the sliding bracket from detaching from the slide groove); the bottom of the upper enclosure 20 is provided with a slot 21 corresponding to the slide groove 11 and the slot 21 is connected to the slide groove 11 (for example, Figure 1 As shown, in order to accommodate the protrusions of the two vertical rods 32, extension grooves are provided on both sides of the bottom of the slide groove 11 and on both sides of the top of the slot 21, respectively, corresponding to the vertical rods.

[0022] Positioning holes are provided in the middle of the two crossbars 31, and positioning components (such as the slots 21 of the upper baffle 20 and the sliding grooves 11 of the lower baffle 10) are respectively provided at the top of the positioning holes of the upper and lower crossbars (after the lower baffle and the upper baffle are unfolded). Figure 1 and Figure 2 (As shown); the positioning component includes a positioning pin 311, a pulling block 312, and a return spring 313. The upper enclosure 20 and the lower enclosure 10 respectively have through holes corresponding to the positioning component, and the through holes correspond to the positioning holes of the upper and lower crossbars 31 (after the lower enclosure and the upper enclosure are unfolded) (in conjunction with Figure 2 and Figure 3As shown), the positioning pin 311 is slidably disposed within the through hole, and a pulling block 312 is provided at the end of the positioning pin 311 furthest from the sliding bracket (i.e., located on the front of the enclosure). A return spring 313 is provided between the pulling block 312 and the corresponding enclosure, and the return spring 313 is located on the outer ring of the positioning pin 311. Annular support seats 310 are provided on the front of the upper enclosure 20 and the lower enclosure 10, located on the outer ring of the corresponding through hole. The positioning pin 311 passes through the middle of the annular support seat 310 and is slidably connected. The return spring 313 is located on the outer ring of the annular support seat 310. The pulling block 312 contacts the side of the annular support seat 310 furthest from the enclosure (e.g., ...). Figure 4 (As shown).

[0023] Connecting lugs 102 are respectively provided on the middle of both sides of the back of the upper baffle 20 and the middle of both sides of the back of the lower baffle 10 (e.g., Figure 1 (As shown) and the two connecting ears 102 of the upper enclosure 20 are offset from the two connecting ears 102 of the lower enclosure 10 (for example: the two connecting ears 102 of the upper enclosure 20 are located on the outermost sides of the upper enclosure 20, and the two connecting ears 102 of the lower enclosure 10 are located on the inner wall of the corresponding positions of the two connecting ears 102 of the upper enclosure 20, such as...). Figure 1 (As shown). A warning bar 103 is provided on the front of the upper enclosure 20 located above the corresponding positioning component and the lower enclosure 10 located below the corresponding positioning component (as shown). Figure 2 (As shown).

[0024] The lower enclosure 10 has transition grooves 12 on both sides of the slide groove 11 (the transition grooves 12 are located between the slide groove 11 and the corresponding connecting lugs 102, such as...). Figure 1 or Figure 5 As shown, a telescopic rod assembly is rotatably installed in the transition groove 12 for further support and fixation of the enclosure.

[0025] Example 2:

[0026] As another preferred embodiment of this utility model, based on the above embodiment 1, the telescopic rod assembly includes a rotating rod 121 and a support rod 122. One end of the rotating rod 122 is rotatably connected to the top of the transition groove 12, and the other end is slidably connected to the support rod 122. The outer diameter of the support rod 122 is smaller than the inner diameter of the rotating rod 121. Multiple connecting holes are evenly provided on one side of the rotating rod 122 along its central axis, and corresponding mounting holes are provided on the support rod 122 along its central axis. The telescopic rod assembly is telescopically limited by inserting a pin into the connecting hole and the corresponding mounting hole.

[0027] Working principle:

[0028] When not in use, the upper enclosure 20 and the lower enclosure 10 are folded, the sliding bracket is completely located in the slide groove 11, and the telescopic rod assembly is located in the adapter groove 12. The upper enclosure 20 and the lower enclosure 10 are connected to the corresponding side connecting ears 102 by fasteners (for example, the connecting ears 102 of the upper enclosure 20 and the lower enclosure 10 are provided with threaded holes in the middle, and screws are screwed into the threaded holes of the connecting ears 102 of the upper enclosure 20 and the lower enclosure 10 in sequence to fix the folded state. At this time, due to the obstruction of the positioning component, the sliding bracket will not slide upward out of the slide groove). In use, first move the entire site enclosure to the desired location and pre-fix it to the ground using bolts. Then, remove the screws on the connecting lugs 102 and rotate the upper enclosure 20 to unfold it. Next, push the sliding bracket upwards. During this process, pull the pull block 312 in real time to prevent the positioning pin 311 from creating a hard limit on the upward movement of the sliding bracket and to stretch the return spring 313. When the sliding bracket presses against the upper side of the slot 21, release the pull block 312. Due to the elastic force of the return spring 313, the positioning pin 311 is engaged in the corresponding positioning hole, thereby achieving a hard limit on the sliding bracket. At this time, the upper enclosure 20 is limited in rotation by the sliding bracket. Finally, rotate the rotating rod 122 and pull out the positioning pin corresponding to the rotating rod 122, causing the support rod 122 to extend until the end of the support rod 122 away from the rotating rod 122 contacts the ground. Insert the positioning pin into the corresponding connecting hole and mounting hole to limit the length of the telescopic rod assembly.

[0029] By connecting the lugs 102, multiple site barriers can be connected and fixed.

[0030] Example 3:

[0031] As another preferred embodiment of the present invention, based on the above embodiment 1, a rubber layer is provided on the bottom surface of the upper enclosure 20 for filling the gap at the joint between the upper enclosure 20 and the lower enclosure after the upper enclosure 20 is unfolded.
