Description

Technical Field

[0001] This invention relates to the field of construction fencing technology, and in particular to a convenient fencing device for construction projects. Background Technology

[0002] Prefabricated fences have advantages such as good reusability, rapid installation and standardized assembly. Due to their high disassembly and assembly efficiency, they can shorten the construction period and meet the needs of rapid site entry and rapid fencing in construction projects. Furthermore, due to the standardized production of components and the flat design of the panels, their aesthetics, cleanliness, construction site environment and corporate image are all improved.

[0003] For example, Chinese Patent Publication No. CN111425061B discloses a prefabricated fence for green construction, which includes a base, columns spaced apart along the length of the base, and barriers between adjacent columns. The base has several first insertion slots spaced apart along its length. Each column has a plug-in block that is plugged into the first insertion slot. The base has a first mounting component for simultaneously restricting adjacent plug-in blocks within their respective first insertion slots. Each column has a first sliding groove extending along its length on the side closest to adjacent columns. Several barriers are arranged along the extension direction of the first sliding grooves between adjacent columns, with both ends of the barriers slidably installed within their corresponding first sliding grooves. The barriers are restricted to adjacent barriers by second mounting components. This design offers high assembly efficiency and allows for disassembly and recycling after construction for use at the next construction site.

[0004] The application involves moving the fence with a lifting device and placing it into the first chute from top to bottom. Then, a positioning rod is inserted and the top fixing nut is rotated to limit the fence's position. However, the installation and removal of the fence require external lifting equipment, and the fence's position is also quite cumbersome, requiring the rotation of the nut on the top of the column for fixing. Since the column itself is usually taller than the workers, its cost and feasibility are limited.

[0005] Therefore, it is necessary to provide a convenient fencing device for construction projects to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a convenient fencing device for construction projects to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, a convenient fencing device for construction projects is designed that allows for quick assembly and disassembly of the panel based on the column and facilitates the limitation of the overall panel position.

[0008] Based on the above ideas, the present invention provides the following technical solution: a convenient fence device for construction projects, comprising a plurality of posts and a plurality of panels disposed between adjacent posts. An opening for panel installation is provided at the bottom of each post, and a limiting component for limiting the bottommost panel is rotatably installed within the opening. A pin corresponding to the position of the limiting component is slidably installed at the corresponding opening on the post. An adjusting component for driving the pin is provided inside the post. When the adjusting component contacts the topmost panel and the bottommost panel in sequence, it can drive the pin to lift a second time, releasing the limiting component.

[0009] As a further aspect of the present invention: the limiting component includes a round rod rotatably installed in the opening, a baffle is fixedly installed on the outer surface of the round rod and a torsion spring is sleeved on its outer surface; when the baffle is flush with the column, the baffle is used to limit the bottom panel; when the baffle is perpendicular to the column, the opening is exposed for panel installation.

[0010] As a further aspect of the present invention: the pin corresponds to the position of the baffle. When the baffle is perpendicular to the column, the pin can slide into the opening and abut against the side wall of the baffle.

[0011] As a further aspect of the present invention: the adjustment component includes a first triggering mechanism for driving the pin to move and a second triggering mechanism corresponding to the position of the first triggering mechanism. The first triggering mechanism is located above the column and corresponds to the top of the uppermost panel, and the second triggering mechanism is located below the column and corresponds to the side of the lowermost panel away from the baffle.

[0012] As a further aspect of the present invention: the first triggering mechanism includes a first connecting rod that is slidably installed inside the column and fixedly connected to the pin, an upper guide post corresponding to the uppermost panel is fixedly installed on the surface of the first connecting rod, and a first spring is fixedly installed between the first connecting rod and the column; the surface of the first connecting rod is provided with a clearance opening and a trapezoidal groove corresponding to the second triggering mechanism, and the clearance opening is located above the trapezoidal groove.

[0013] As a further aspect of the present invention: the second triggering mechanism includes a second connecting rod slidably installed inside the column, one end of the second connecting rod is fixedly installed with a side guide post corresponding to the bottommost panel, and the other end corresponds to the clearance opening, and a second spring is fixedly installed between the second connecting rod and the column.

[0014] As a further embodiment of the present invention: the interior of the column is provided with a vertical groove along the vertical direction for the placement of the first connecting rod, the first spring and the upper guide post, and the interior of the column is provided with a horizontal groove along the horizontal direction for the placement of the second connecting rod, the second spring and the side guide post, and the vertical groove is provided with space for avoiding the second connecting rod.

[0015] As a further aspect of the present invention: the length of the clearance opening in the vertical direction is greater than the length of the second connecting rod in the vertical direction; when the first connecting rod is not raised, the second connecting rod is horizontally aligned with the clearance opening, and when the first connecting rod is raised, the second connecting rod is horizontally aligned with the trapezoidal groove.

[0016] As a further embodiment of the present invention: a slot is provided on the top of the baffle, and a lifting component is provided at the corresponding opening of the column, which is fixedly connected to the pin and corresponds to the position of the slot; when the pin retracts into the column and the baffle returns to the opening, the lifting component can descend and be inserted into the slot.

[0017] As a further embodiment of the present invention: the lifting assembly includes a locking block that is slidably installed inside the column and adapted to the locking slot. A third spring is fixedly installed between the top of the locking block and the column. A traction rope is fixedly installed between the top of the locking block and the top of the pin. The traction rope is arranged in an inverted U-shape so that the moving directions of the locking block and the pin are opposite.

[0018] Compared with the prior art, the beneficial effects of the present invention are: through the cooperation between the limiting component, the pin and the adjusting component, several panels are assembled from bottom to top based on the column. When all the panels are assembled, the column and the limiting component complete the overall limiting. At this time, there is no need to move the panels back and forth with the lifting tool, and the limiting method of the panels is simpler. There is no need to equip tools such as screwdrivers and bolts, which can effectively reduce the labor burden of workers.

[0019] Several panels are stacked one on top of the other after installation, which has a good stabilizing effect on the overall panel and can prevent the panels from shifting forward or backward. With the limit components to limit the bottom panel and the automatic reset of the limit components after all panels are installed, the panel limiting speed is faster, which can further improve the overall assembly and disassembly efficiency of the fence device.

[0020] When multiple panels are installed on a column, the pins can automatically extend to limit the limiting components, preventing the pins from resetting and affecting the quick installation and removal of the panels. This eliminates the need for workers to repeatedly switch the limiting components on and off. After the top panel is installed, the pins are raised once, and after the bottom panel is installed, the pins are raised a second time. This automatically releases the limiting components, allowing them to reset and press against the bottom panel. This further simplifies the installation process and improves the overall installation and removal efficiency.

[0021] The posts and panels are highly reusable and can be freely replaced, thus allowing for greater freedom in the assembly of the fence device. Workers do not need to restrict the installation sequence of the panels, and the operating area is located below the posts, which reduces the requirements for the installation process and subsequent maintenance and disassembly, significantly improving the practicality and applicability of the fence device.

[0034] Example 1:

[0035] Please see Figures 1 to 6This invention provides a convenient fencing device for construction projects, mainly used to enable the quick assembly and disassembly of panels 2 based on posts 1, thereby improving the ease of use of the fencing device. The device includes posts 1 and several panels 2. During use, the posts 1 are fixed to the ground or anchor rods with bolts, making the posts 1 relatively fixed. The panels 2 are all slidably engaged with the posts 1. In this embodiment, there are six panels 2, arranged vertically and horizontally. Correspondingly, the left and right sides of the posts 1 are provided with sliding grooves 101 for the panels 2 to slide on. These grooves 101 can be T-shaped or dovetail grooves to allow the panels 2 to slide and prevent them from detaching. In the above structure, the posts 1, panels 2, and sliding grooves 101 are all existing mature technologies and will not be described in detail here.

[0036] Furthermore, such as Figure 2 As shown, the bottom of the column 1 has an opening 105. The opening 105 is designed to allow the panels 2 to be placed into the column 1 from bottom to top. At this time, the five upper panels 2 are automatically limited by the slide groove 101, while the bottom panel 2 is not limited. Therefore, a limiting component 3 for limiting the bottom panel 2 is rotatably installed in the opening 105. This limits all six panels 2 on the column 1, and simplifies the installation of the panels 2, eliminating the need to move the panels 2 up and down with a hoist for assembly.

[0037] Furthermore, such as Figure 2 As shown, a pin 4 is slidably installed on the column 1 at the opening 105. An adjustment component 5 for driving the pin 4 is provided inside the column 1. The adjustment component 5 makes the pin 4 tend to descend from the column 1 into the opening 105. Then, after the limiting component 3 rotates out of the opening 105, the side wall of the pin 4 can abut against the limiting component 3, so that the limiting component 3 cannot automatically reset to the opening 105. At this time, the panel 2 can be quickly placed into the slide groove 101 because there is no longer a structural obstruction at the opening 105.

[0038] In the above structure, such as Figure 1 and Figure 2 As shown, the adjustment component 5 is arranged above and below the slide 101. The upper structure of the adjustment component 5 corresponds to the uppermost panel 2, and its lower structure corresponds to the lowermost panel 2. When the panels 2 are installed from bottom to top into the slide 101 and all six panels 2 are installed, the uppermost panel 2 contacts the upper structure of the adjustment component 5 and the lowermost panel 2 contacts the lower structure of the adjustment component 5, causing the pin 4 to be lifted a second time. At this time, the pin 4 retracts from the opening 105 into the column 1 and releases the abutment state with the limiting component 3. The limiting component 3 can automatically rotate in the opposite direction to reset and enter the opening 105, abutting against the surface of the lowermost panel 2.

[0039] It should be noted that, as Figure 1 As shown in this embodiment, only one section of the fence device is displayed. In practical applications, the number of sections can be increased accordingly to meet the protective effect. In this case, the number of posts 1 will increase accordingly, and the panel 2 will be placed between two adjacent posts 1. After the entire fence device is installed, the limiting component 3 is located on one side of the construction site, which facilitates quick assembly and disassembly by workers, thereby improving the ease of use of the fence device and preventing external pedestrians from moving the limiting component 3.

[0040] Reference Figure 2 and Figure 6 In this embodiment, preferably, the limiting component 3 includes a round rod 301 rotatably mounted in the opening 105. A baffle 302 is fixedly mounted on the outer surface of the round rod 301. When the baffle 302 is flush with the column 1, the baffle 302, as part of the lower part of the slide groove 101, jointly limits the lowermost panel 2. When the baffle 302 is perpendicular to the column 1, the opening 105 is exposed, allowing the panel 2 to be quickly placed into the slide groove 101. A torsion spring (not shown in the figure) is also fitted on the outer surface of the round rod 301. The torsion spring causes the round rod 301 to drive the baffle 302 to tend to be flush with the column 1.

[0041] In the above structure, when the baffle 302 is perpendicular to the column 1, and the adjusting component 5 causes the pin 4 to descend into the opening 105, the side wall of the pin 4 can abut against the baffle 302, that is... Figure 6 In the state of being blocked, the baffle 302 is unable to reset into the opening 105, so that the opening 105 is exposed and the panel 2 can be quickly picked up and put on based on the slide 101.

[0042] Reference Figures 2 to 6 In this embodiment, preferably, the adjustment component 5 includes a first triggering mechanism for driving the pin 4 to move up and down, and a second triggering mechanism corresponding to the position of the first triggering mechanism. The first triggering mechanism is the upper structure of the adjustment component 5, corresponding to the uppermost panel 2 in the slide groove 101, and the second triggering mechanism is the lower structure of the adjustment component 5, corresponding to the lowermost panel 2 in the slide groove 101. When the panel 2 enters the slide groove 101, it immediately contacts the second triggering mechanism. At this time, although the second triggering mechanism moves, the position of the pin 4 remains unchanged because the first triggering mechanism is not triggered.

[0043] Among them, such as Figure 3As shown, the first triggering mechanism includes a first connecting rod 502 slidably installed inside the column 1 and fixedly connected to the pin 4. An upper guide post 501 is fixedly installed on the surface of the first connecting rod 502. The upper guide post 501 is inserted from above the slide groove 101 and corresponds to the top of the uppermost panel 2. A first spring 503 is fixedly installed between the first connecting rod 502 and the column 1. The first spring 503 causes the first connecting rod 502 to have a tendency to slide down along the inside of the column 1, and also causes the upper guide post 501 to have a tendency to move into the slide groove 101. When the panel 2 is placed at the top of the slide groove 101, the top of the uppermost panel 2 pushes the upper guide post 501 to rise, and the upper guide post 501 drives the first connecting rod 502 to rise and squeeze the first spring 503.

[0044] In the above structure, such as Figure 4 As shown, the surface of the first connecting rod 502 is provided with a clearance opening 504 and a trapezoidal groove 505 corresponding to the second triggering mechanism. The clearance opening 504 is located above the trapezoidal groove 505, and the trapezoidal groove 505 is a right-angled trapezoid. When the first connecting rod 502 is not rising, the second triggering mechanism corresponds to the clearance opening 504. At this time, even if the second triggering mechanism contacts the bottom panel 2 and moves, the second triggering mechanism will only move along the clearance opening 504 and will not cause the first connecting rod 502 to move. When the first connecting rod 502 rises, the second triggering mechanism corresponds to the trapezoidal groove 505. At this time, if the second triggering mechanism moves, it will contact the trapezoidal groove 505, causing the first connecting rod 502 to rise further along the column 1. Specifically, the first connecting rod 502 has an L-shaped design, the upper guide post 501 is fixedly installed on one end surface of the first connecting rod 502, and the clearance opening 504 and the trapezoidal groove 505 are opened on the other end surface of the first connecting rod 502.

[0045] Among them, such as Figure 4 and Figure 5 As shown, the second triggering mechanism includes a second connecting rod 507 slidably installed in the column 1. One end of the second connecting rod 507 is fixedly installed with a side guide post 506 extending into the slide groove 101. The side guide post 506 corresponds to the rear surface of the panel 2. The other end of the second connecting rod 507 corresponds to the clearance opening 504. A second spring 508 is fixedly installed between the second connecting rod 507 and the column 1. The second spring 508 causes the second connecting rod 507 to have a tendency to move away from the first connecting rod 502, and also causes the side guide post 506 to have a tendency to move into the slide groove 101.

[0046] Correspondingly, such as Figures 3 to 5As shown, the interior of the column 1 has a vertical groove 102 along the vertical direction. The vertical groove 102 is used to place the first connecting rod 502, the first spring 503 and the upper guide post 501. The interior of the column 1 has a horizontal groove 103 that communicates with the vertical groove 102 along the horizontal direction. The horizontal groove 103 is used to place the second connecting rod 507, the second spring 508 and the side guide post 506. The second connecting rod 507 extends into the vertical groove 102 and corresponds to the clearance opening 504.

[0047] Furthermore, such as Figure 4 As shown, the length of the clearance opening 504 in the vertical direction is greater than that of the second link 507 in the vertical direction. This means that when the side guide post 506 contacts the bottom panel 2 and retracts into the horizontal groove 103, even if the second link 507 moves along the horizontal groove 103, it will only move within the clearance opening 504 and will not cause the first link 502 to rise. At the same time, the vertical groove 102 has space for the second link 507 to move up and down, so that when the first link 502 rises within the vertical groove 102, it will not interfere with the second link 507.

[0048] It should be noted that, as Figure 4 As shown, when the first link 502 rises and causes the clearance opening 504 to be misaligned with the second link 507, the second link 507 can then correspond to the trapezoidal groove 505. Specifically, the second link 507 corresponds to the inclined surface of the trapezoidal groove 505. At this time, if the second link 507 moves along the transverse groove 103 and approaches the trapezoidal groove 505, it can drive the first link 502 to rise a second time through the trapezoidal groove 505.

[0049] In use, first fix the column 1 and then rotate the baffle 302 so that it is perpendicular to the column 1. At this time, the pin 4 descends through the first connecting rod 502 and the first spring 503 and abuts against the baffle 302, so that the baffle 302 is limited and cannot be reset to the opening 105. Then, the panel 2 is installed from the opening 105 into the slide groove 101. When the panel 2 is installed from bottom to top in the slide groove 101, even if it comes into contact with the side guide post 506 and causes the second connecting rod 507 to move along the clearance opening 504, the first connecting rod 502 will not move and cause the pin 4 to deviate. After the top panel 2 is installed and abuts against the upper guide post 501, the upper guide post 501 drives the pin 4 to lift once through the first connecting rod 502. At this time, the pin 4 is still abutting against the baffle 302, and the clearance 504 is misaligned with the second connecting rod 507, while the trapezoidal groove 505 corresponds to the second connecting rod 507. After the bottom panel 2 (i.e. the last panel 2) is installed, the bottom panel 2 drives the side guide post 506 to retract into the transverse groove 103. The side guide post 506 drives the pin 4 to lift a second time through the second connecting rod 507, the trapezoidal groove 505 and the first connecting rod 502, so that the pin 4 retracts into the column 1 and releases the restriction on the baffle 302. At this time, the baffle 302 automatically flips under the action of the torsion spring, and finally the baffle 302 can abut against the front surface of the bottom panel 2.

[0050] In summary, through the cooperation of structures such as baffle 302, pin 4, first connecting rod 502 and second connecting rod 507, several panels 2 are assembled from bottom to top in the slide groove 101. After all panels 2 are assembled, the upper panels 2 are limited by the slide groove 101 and the lower panel 2 is limited by the baffle 302. Therefore, the entire panel 2 can be effectively limited. At this time, there is no need to move the panel 2 back and forth with a lifting device. Moreover, the limiting method of the panel 2 is simpler. There is no need to equip tools such as screwdrivers and bolts, which can effectively reduce the labor burden of workers and thus has higher practicality.

[0051] Several panels 2 are stacked one on top of the other after installation, which has a good stabilizing effect on the overall panel 2 and can prevent the panel 2 from shifting back and forth. With the baffle 302 limiting the bottom panel 2 and the baffle 302 automatically resetting after all panels 2 are installed, the limiting speed of the panel 2 is faster, which can further improve the overall assembly and disassembly efficiency of the fence device.

[0052] When several panels 2 are installed into the slide groove 101, the pin 4 can automatically extend to limit the baffle 302, preventing the pin 4 from resetting and affecting the quick installation and removal of the panels 2. This saves workers from repeatedly opening and closing the baffle 302. After the uppermost panel 2 is installed, the pin 4 is lifted once, and after the lowermost panel 2 is installed, the pin 4 is lifted a second time. This can automatically release the limit on the baffle 302 and reset it to press against the lowermost panel 2, thereby further simplifying the installation steps and improving the overall installation and removal efficiency.

[0053] The structure, including the posts 1 and panels 2, has high reusability and can be freely replaced during replacement. Therefore, the assembly of the fence device is more flexible, and workers do not need to limit the installation sequence of the panels 2. Moreover, the operating area is located below the posts 1, so the requirements for the installation process of the panels 2 and the subsequent maintenance and disassembly process are lower, which significantly improves the practicality and applicability of the fence device.

[0054] Example 2:

[0055] Please see Figures 1 to 9 Based on Embodiment 1, in order to further improve the stability of the overall panel 2 after installation, a lifting component 6 fixedly connected to the pin 4 is provided at the opening 105 corresponding to the column 1. When the pin 4 descends into the opening 105, the lifting component 6 can retract into the column 1. At this time, the lifting component 6 will not interfere with the rapid assembly of the panel 2 from the opening 105 into the slide groove 101. After the pin 4 retracts into the column 1, the lifting component 6 can descend into the opening 105. When the baffle 302 automatically resets to the opening 105, the lifting component 6 can be pushed up first, and then the baffle 302 can complete the reset. At this time, the lifting component 6 resumes descent and inserts into the baffle 302.

[0056] Correspondingly, such as Figure 7 As shown, the top of the baffle 302 is provided with a slot 303 corresponding to the position of the lifting component 6. When the lifting component 6 is inserted into the baffle 302, it enters the slot 303. At this time, the lifting component 6 limits the baffle 302, so that the baffle 302 can no longer rotate out of the opening 105, thereby effectively limiting the bottom panel 2, which can further improve the limiting effect and stability of the overall panel 2.

[0057] Reference Figures 7 to 9 In this embodiment, preferably, the lifting assembly 6 includes a locking block 601 that is slidably installed in the column 1 and adapted to the locking slot 303. A third spring 602 is fixedly installed between the top of the locking block 601 and the column 1. The third spring 602 causes the locking block 601 to have a downward tendency. A traction rope 603 is fixedly installed between the top of the locking block 601 and the top of the pin 4. The traction rope 603 is arranged in an inverted U-shape so that the moving directions of the locking block 601 and the pin 4 are opposite.

[0058] Among them, such as Figure 8 As shown, the interior of the column 1 is provided with a mounting groove 104 that communicates with the opening 105 and the vertical groove 102 for mounting the locking block 601, the third spring 602 and the traction rope 603. In order to facilitate the subsequent manual movement of the locking block 601, a lever 604 extending out of the column 1 is fixedly installed on the surface of the locking block 601.

[0059] Correspondingly, such as Figure 8As shown, the bottom of the locking block 601 and the side away from the slide groove 101 have an arc surface. The arc surface is used to allow the locking block 601 to automatically retract into the placement groove 104 when the baffle 302 resets to the opening 105. At this time, the third spring 602 is squeezed and the traction rope 603 is released, but the pin 4 will not move due to the drive of the first connecting rod 502.

[0060] In use, through the first connecting rod 502 and the second connecting rod 507, several panels 2 are assembled and limited in the slide groove 101 from bottom to top. The working process and effect of this part are the same as in Embodiment 1, and will not be repeated here. The difference is: first, the toggle block 604 is moved up to separate the locking block 601 from the slot 303, then the baffle 302 is rotated to make the pin 4 descend and lock the baffle 302, and then the panels 2 are installed in sequence; after all the panels 2 are installed, the pin 4 is lifted and retracted into the column 1 and the traction rope 603 is released. At this time, the locking block 601 descends into the opening 105 under the action of the third spring 602. At the same time, the baffle 302 resets to the opening 105 and pushes the locking block 601 up through the arc surface. After the baffle 302 is reset, the locking block 601 descends again and inserts into the slot 303, which can effectively limit the baffle 302.

[0061] Compared to Embodiment 1, through the cooperation of structures such as the slot 303, pin 4, block 601 and traction rope 603, when the pin 4 is retracted into the column 1 after a second lifting, the block 601 can extend out of the column 1 and enter the opening 105. After the baffle 302 is reset based on the opening 105, the block 601 can be inserted into the slot 303 to effectively limit its movement, thereby preventing the baffle 302 from rotating after installation, which can further improve the limiting effect and stability of the overall panel 2.

[0062] When the baffle 302 rotates out into the slide groove 101 and the panel 2 is installed in sequence, the locking block 601 can automatically retract into the column 1 through the pin 4. At this time, the locking block 601 will not interfere with the panel 2. Therefore, the panel 2 can still be quickly disassembled and assembled relative to the slide groove 101 based on the opening 105, which can further ensure the disassembly and assembly efficiency of the panel 2 and ensure the use effect of the fence device.

[0063] Example 3:

[0064] Please see Figures 1 to 10 Based on Embodiment 2, in order to further improve the disassembly and assembly efficiency of panel 2, the position of the side guide post 506 is improved: at this time, the top surface of the side guide post 506 is flush with the top surface of the bottom panel 2, so that after the panel 2 is installed and lifted into the slide groove 101 in sequence, the top surface of the side guide post 506 can support the corresponding panel 2 above. When installing the next panel 2, the process of lifting the already installed panel 2 again can be eliminated, thereby further improving the disassembly and assembly efficiency of panel 2.

[0065] In use, through structures such as the first connecting rod 502 and the second connecting rod 507, several panels 2 are assembled and positioned from bottom to top within the slide groove 101. Through structures such as the locking block 601 and the traction rope 603, after the baffle 302 resets, the locking block 601 can be inserted into the locking slot 303 to effectively position it. The working process and effect of this part are the same as in Embodiment 2, and will not be repeated here. The difference is that when installing the panel 2 into the slide groove 101, the panel 2 can push the side guide post 506 into the column 1, and then lift the panel 2 until the side guide post 506 resets and extends. At this time, the lifted panel 2 can be supported by the side guide post 506, and other panels 2 can be installed in the same way.

[0066] Compared to Embodiment 2, through the cooperation of structures such as the slide groove 101, the side guide post 506, and the bottom panel 2, the side guide post 506 can retract during the installation of the panel 2 without affecting the lifting of the panel 2 along the slide groove 101. The side guide post 506 can automatically extend to support the lifted panel 2. During the removal of the panel 2 and the removal of the bottom panel 2, the side guide post 506 also extends to support the upper panel 2. Therefore, the upper panel 2 will not immediately drop during the removal process, which can reduce the collision damage between the panel 2 and the column 1 and extend the service life of the panel 2 and the column 1.

[0067] The overall design is integrated with the installation position of the side guide post 506 without any adjustment to the shape or structure of the panel 2. It has a significant beneficial effect on the quick assembly and disassembly of the overall panel 2. When installing the next panel 2, the worker does not need to repeatedly lift the already installed panel 2. Therefore, the installation steps of the panel 2 are further simplified, the labor burden of the workers is further reduced, and the practicality of the fence device is further improved.
