[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] See Figures 1 to 2 The figure shows a preferred structure of the construction site isolation fence in this embodiment. As shown, the construction site isolation fence includes: two support columns 1, a fencing mechanism, a clamping device, and two splicing mechanisms 4. The two support columns 1 are arranged side-by-side with a certain distance between them, which can be determined according to actual conditions; this embodiment does not impose any restrictions on this distance. The bottom of each support column 1 is used for insertion into the ground. Specifically, each support column 1 has a base plate 5 at its bottom, with multiple insertion holes. Each insertion hole corresponds to a nail 6, and each nail 6 passes through the corresponding insertion hole and is inserted into the ground.

[0021] Two splicing mechanisms 4 correspond one-to-one with two support columns 1, with each splicing mechanism 4 positioned on top of its corresponding support column 1. Specifically, each splicing mechanism 4 includes a connecting plate 41 and a splicing plate 42. The connecting plate 41 is horizontally positioned on top of the support column 1, perpendicular to it. The splicing plate 42 is vertically positioned on the side wall of the connecting plate 41, parallel to the support column 1. The connecting plate 41 and the splicing plate 42 form a T-shaped structure, with the splicing plate 42 positioned outside the support column 1. The splicing plate 42 contacts and is bolted to the splicing plate 42 in an adjacent construction isolation fence. Specifically, the splicing plate 42 has through holes, and the positions of the through holes on the splicing plates 42 in each splicing mechanism 4 are corresponding. Multiple construction isolation fences can be set up according to construction needs. The construction isolation fences are connected in sequence. When two adjacent construction isolation fences are connected, the splicing mechanism 4 in the two adjacent construction isolation fences corresponds to each other, that is, the splicing plate 42 in the two adjacent construction isolation fences corresponds to each other and is in contact. The through holes on the two splicing plates 42 also correspond to each other. The bolts are passed through the through holes on the two splicing plates 42 in sequence and then screwed into the nuts, so that the two adjacent construction isolation fences are connected together by the splicing plate 42 and the bolts.

[0022] The fencing mechanism is positioned between two supporting columns 1, and the fencing mechanism itself is foldable. Specifically, the fencing mechanism includes: multiple fencing components 2 arranged side by side. Each fencing component 2 is foldable, each fencing component 2 is horizontally positioned between two supporting columns 1, and each fencing component 2 is aligned along the height direction of the supporting columns 1. Figure 1 The fencing components 2 are spaced out from top to bottom, with a preset distance between each adjacent component. This preset distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on it. The folding positions of each fencing component 2 are corresponding, so that each fencing component 2 folds according to the folding position, which facilitates the folding of the fencing mechanism.

[0023] Each enclosure assembly 2 includes: two rotating sleeves 21, two first enclosure plates 22, and a second enclosure plate 23. The two rotating sleeves 21 correspond one-to-one with the two support columns 1, and each rotating sleeve 21 is rotatably fitted onto the corresponding support column 1, so that the rotating sleeve 21 can rotate relative to the support column 1.

[0024] The first ends of the two first enclosure plates 22 are respectively connected to the two rotating sleeves 21 in a fixed manner. The second ends of the two first enclosure plates 22 correspond to the two ends of the second enclosure plate 23, and the second end of each first enclosure plate 22 is rotatably connected to the corresponding end of the second enclosure plate 23. Specifically, the second enclosure plate 23 is placed between the two first enclosure plates 22, and the two ends of the second enclosure plate 23 are hinged to the second ends of the two first enclosure plates 22 respectively.

[0025] The lengths of the first baffle plate 22 and the second baffle plate 23 in each of the fencing components 2 are equal. Specifically, the lengths of the second baffle plate 23 in each of the fencing components 2 are equal, and the lengths of the first baffle plate 22 in each of the fencing components 2 are also equal. The lengths of the two first baffle plates 22 in the same fencing component 2 are also equal. In this way, the positions of the connection points between the second baffle plate 23 and the two first baffle plates 22 in each fencing component 2 are all corresponding, so that the folding positions of each fencing component 2 are all corresponding, which facilitates the folding or unfolding of the fencing component 2.

[0026] When the fencing assembly 2 is unfolded, the two support columns 1 are pulled to both sides, causing the rotating sleeve 21 to rotate on the support columns 1. Simultaneously, the second fencing panel 23 and the two first fencing panels 22 rotate relative to each other until they are aligned in a straight line, and the fence is in its unfolded state. After the base plate 5 is fixed, the second fencing panel 23 and the two first fencing panels 22 provide protection. When the fencing assembly 2 is folded, the two support columns 1 are pushed inward, bringing them closer together. The second fencing panel 23 and the two first fencing panels 22 rotate relative to each other, thus achieving the folding effect.

[0027] A clamping device is positioned between two support columns 1 and is used to clamp the promotional page 7. Specifically, the clamping device includes multiple clamping mechanisms. These mechanisms are arranged in parallel, each positioned between two support columns 1, and spaced apart along the height of the support columns 1. Each clamping mechanism is used to clamp the promotional page 7.

[0028] Along the height direction of the support column 1, each clamping mechanism and each enclosure component 2 are staggered. Specifically, a clamping mechanism is set between two adjacent enclosure components 2.

[0029] In practice, the number of fencing components 2 and the number of clamping mechanisms can be determined according to the actual situation, and this embodiment does not impose any restrictions on them. In this embodiment, there are three fencing components 2 and two clamping mechanisms.

[0030] When the construction site isolation fence is needed, pull the two support columns 1 to both sides to unfold each fence component 2, and insert the pins 6 through the holes on the base plate 5 into the ground to fix the base plate 5. After the base plate 5 is fixed, each fence component 2 provides isolation and protection. When advertising is needed, the advertising leaflets 7 can be pressed and fixed by the clamping mechanisms to secure the advertising leaflets 7. When multiple construction site isolation fences need to be connected, the splicing plates 42 of two adjacent construction site isolation fences are brought into contact and fixed by bolts.

[0031] As can be seen, in this embodiment, two support columns 1 are inserted into the ground, and a fencing mechanism is set between the two support columns 1. This fencing mechanism provides isolation and protection, and it is foldable, allowing the fencing to be folded to a certain extent for easy transportation. A pressing device is set between the two support columns 1 to press the promotional page 7, thus fixing the promotional page 7 and enabling it to achieve the effect of promotion. In this way, the isolation fence achieves both isolation and protection and promotion, solving the problem that the isolation fence in the prior art cannot be folded and cannot fix the poster. When multiple isolation fences need to be connected, the splicing mechanism 4 at the top of the support column 1 connects two adjacent isolation fences, realizing the connection of multiple isolation fences. This is simple, convenient, and easy to implement.

[0032] See Figure 1 and Figure 2 In the above embodiments, each clamping mechanism includes two clamping components 3. Each clamping component 3 corresponds one-to-one with one of the two support columns 1, and each clamping component 3 is disposed on its corresponding support column 1. Furthermore, the two clamping components 3 are aligned with the length direction of the promotional page 7. Figure 1The two ends of the page 7 (shown from left to right) correspond one-to-one, and each clamping component 3 is used to clamp the corresponding end of the promotional page 7.

[0033] See Figure 1 and Figure 2 Each clamping assembly 3 includes: a mounting body 31, a drive structure, and two clamping plates 32. The first side of the mounting body 31 is located on the side of the corresponding support column 1 facing the other support column 1, and the second side of the mounting body 31 has a receiving groove 311 that is recessed towards the first side of the mounting body 31, and the opening of the receiving groove 311 faces the other support column 1.

[0034] The two clamping plates 32 are arranged side by side, and both clamping plates 32 are movably disposed within the receiving groove 311. Both clamping plates 32 are arranged along the height direction of the mounting body 31. Figure 2 Extending in the direction shown from top to bottom, the height direction of the mounting body 31 is consistent with the height direction of the support column 1 and the height direction of the receiving groove 311, and the moving direction of the two clamping plates 32 is the width direction of the mounting body 31. Figure 2 The direction shown is from left to right, that is Figure 1 (perpendicular to the paper surface), wherein the width direction of the mounting body 31 is consistent with the width direction of the receiving groove 311. The end of the promotional page 7 is clamped between the two clamping plates 32.

[0035] The drive structure is disposed in the receiving groove 311 and is connected to two clamping plates 32. The drive structure is used to drive the two clamping plates 32 to move closer together to clamp the promotional page 7.

[0036] See Figure 1 and Figure 2 The driving structure includes a driving assembly 33 and two transmission assemblies 34. The two transmission assemblies 34 are respectively disposed on two opposite sidewalls along the width direction within the receiving groove 311. Specifically, the receiving groove 311 has a rectangular cross-section, and two transmission assemblies 34 are respectively disposed on two opposite sidewalls along the width direction of the receiving groove 311. The height direction of the receiving groove 311 is the length direction of the rectangle. One transmission assembly 34 is rotatably connected to one end of the two clamping plates 32, and the other transmission assembly 34 is rotatably connected to the other end of the two clamping plates 32. Specifically, since the two clamping plates 32 extend along the height direction of the mounting body 31, the positions of the two ends of the two clamping plates 32 correspond one-to-one, and the two ends of each clamping plate 32 correspond to and are rotatably connected to the two transmission assemblies 34 respectively. In this embodiment, the first end of the two clamping plates 32 ( Figure 2 The upper end shown is rotatably connected to the transmission assembly 34 located above, and the second ends of the two clamping plates 32 ( Figure 2 The lower end shown is rotatably connected to the transmission assembly 34 located below.

[0037] The drive assembly 33 is disposed on one of the side walls of the mounting body 31 in the height direction, and the drive assembly 33 is connected to one of the clamping plates 32. The drive assembly 33 is used to drive the clamping plate 32 connected to it to move to the other clamping plate 32, and to drive the two clamping plates 32 to move closer to each other through the two transmission assemblies 34 to clamp the promotional page 7.

[0038] See Figure 1 and Figure 2 The drive assembly 33 includes a throttle 331, a threaded cylinder 332, and a threaded rod 333. The threaded cylinder 332 is rotatably disposed within one of the side walls of the receiving groove 311 in the height direction. Specifically, the threaded cylinder 332 is placed within the receiving groove 311 and is rotatably connected to one of the side walls of the receiving groove 311 in the height direction. The first end of the threaded rod 333 is screwed to the threaded cylinder 332, and the second end of the threaded rod 333 is connected to one of the clamping plates 32.

[0039] The first end of the throttle 331 is located outside the mounting body 31. The throttle 331 is rotatably inserted through the side wall of the receiving groove 311, and the second end of the throttle 331 is connected to the threaded cylinder 332 in a fixed connection. The throttle 331 is used to rotate under the control of the operator, which drives the threaded cylinder 332 to rotate. Since the threaded cylinder 332 is screwed to the threaded rod 333, the rotation of the threaded cylinder 332 drives the threaded rod 333 to move, which in turn drives the pressure plate 32 connected to the threaded rod 333 to move, causing the pressure plate 32 to move closer to another pressure plate 32.

[0040] Each transmission assembly 34 includes: a transmission column 341, a connecting sleeve 342, a baffle 343, and two pull rods 344. The first end of the transmission column 341 is disposed on the side wall along the width direction inside the receiving groove 311, the position of the transmission column 341 is between the two clamping plates 32, and the second end of the transmission column 341 is perpendicularly connected to the baffle 343.

[0041] The connecting sleeve 342 is slidably fitted onto the outside of the transmission column 341. Two pull rods 344 are located on both sides of the connecting sleeve 342, and each pull rod 344 corresponds to one of the two clamping plates 32. The two ends of each pull rod 344 are rotatably connected to the ends of the connecting sleeve 342 and the corresponding clamping plate 32, respectively. Specifically, one end of each pull rod 344 is rotatably connected to the connecting sleeve 342, such as a hinged connection, and the other end of each pull rod 344 is rotatably connected to the end of the corresponding clamping plate 32, such as a hinged connection. The diameter of the baffle 343 is larger than the inner diameter of the connecting sleeve 342 to block the connecting sleeve 342 and prevent it from detaching from the transmission column 341, allowing the connecting sleeve 342 to slide along the transmission column 341.

[0042] Preferably, the drive structure further includes a plurality of guide components 35. Each guide component 35 is disposed between the two clamping plates 32 and the corresponding sidewalls of the receiving groove 311, and each guide component 35 is used to restrict the movement direction of the clamping plates 32.

[0043] Each guide assembly 35 includes a guide rod 351 and a guide sleeve 352. The guide rod 351 has a preset length, which can be determined according to actual conditions; this embodiment does not impose any limitation on this length. The guide rod 351 is connected to the side wall of the receiving groove 311 in the height direction. The first end of the guide sleeve 352 is movably disposed on the guide rod 351, and the second end of the guide sleeve 352 is connected to the corresponding pressing plate 32.

[0044] In practical implementation, the length of the guide rod 351 should be sufficient to ensure the movement of the guide sleeve 352 and to ensure that the two clamping plates 32 clamp the promotional page 7. That is, when the two clamping plates 32 clamp the promotional page 7, the guide sleeve 352 can still move along the guide rod 351. The guide sleeve 352 is not limited by the length of the guide rod 351, thus avoiding the situation where the guide rod 351 is too short, causing the two clamping plates 32 to fail to clamp the promotional page 7 when the guide sleeve 352 is fully extended. The specific length of the guide rod 351 can be determined according to actual conditions; this embodiment does not impose any restrictions on it.

[0045] In practice, there are four guide components 35, with two guide components 35 corresponding to each clamping plate 32.

[0046] When pressing the promotional page 7, the end of the promotional page 7 is placed between the two pressing plates 32 in the corresponding pressing assembly 3. The operator turns the handle 331, which drives the threaded cylinder 332 to rotate. Since the threaded cylinder 332 is screwed to the threaded rod 333, the rotation of the threaded cylinder 332 drives the threaded rod 333 to move, which in turn drives the pressing plate 32 connected to the threaded rod 333 to move, so that the pressing plate 32 moves closer to the other pressing plate 32. The clamping plate 32 connected to the threaded rod 333 is designated as the first clamping plate 32, and the other clamping plate 32 is designated as the second clamping plate 32. When the threaded rod 333 pushes the first clamping plate 32 to move, the movement of the first clamping plate 32 pushes the pull rods 344 at both ends of the first clamping plate 32 to move away from each other (i.e., move towards their respective sidewalls in the width direction of the receiving groove 311). In this way, the pull rods 344 at both ends of the first clamping plate 32 drive the two connecting sleeves 342 to move away from each other along the transmission column 341 (i.e., move towards their respective sidewalls in the width direction of the receiving groove 311). The movement of the two connecting sleeves 342 simultaneously pulls the pull rods 344 at both ends of the second clamping plate 32 to move away from each other, thereby driving the second clamping plate 32 to move closer to the first clamping plate 32. Then, the two clamping plates 32 move closer together and thus press the end of the promotional page 7.

[0047] When it is necessary to remove the promotional page 7, turn the handle 331 in the opposite direction. The handle 331 drives the threaded cylinder 332 to rotate in the opposite direction, which in turn drives the threaded rod 333 to move towards the side wall in the height direction of the receiving groove 311. This in turn drives the first pressing plate 32 to move away from the second pressing plate 32. The first pressing plate 32 drives the second pressing plate 32 to move through the two transmission components 34, so that the first pressing plate 32 and the second pressing plate 32 move away from each other, and the promotional page 7 is no longer pressed, so the promotional page 7 can be removed.

[0048] When the two clamping plates 32 move, each clamping plate 32 drives the guide sleeve 352 on it to move along the corresponding guide rod 351, which restricts the movement direction of the guide sleeve 352, and thus restricts the movement direction of the clamping plate 32.

[0049] In summary, in this embodiment, two support columns 1 are inserted into the ground, and a fencing mechanism is set between the two support columns 1. This fencing mechanism provides isolation and protection, and it is foldable, allowing the fencing to be folded to a certain extent for easy transportation. A clamping device is set between the two support columns 1 to clamp the promotional page 7, thus fixing the promotional page 7 and enabling it to achieve the effect of promotion. In this way, the isolation fence achieves both isolation and protection and promotion. When multiple isolation fences need to be connected, the splicing mechanism 4 at the top of the support column 1 connects two adjacent isolation fences, realizing the connection of multiple isolation fences. This is simple, convenient, and easy to implement.
