Description

Technical Field

[0001] The present application relates to the field of partition devices, and in particular to a fence. Background Art

[0002] A fence refers to a structure or facility used to enclose, restrict or protect a specific area. Fences are widely used in our production and life. The main functions of fences include defining boundaries, providing security protection, preventing intrusion, maintaining privacy and beautifying the environment. There are garden fences, highway fences, municipal fences and so on.

[0003] Existing fences are usually installed with auxiliary bolts and other parts, which takes time and effort to install, and requires tools to operate, resulting in low installation efficiency. Metal fences are installed by welding, which takes a long time to install and requires experienced and skilled welders to complete, resulting in high labor costs. After welding, the fence is an integrated structure, which is difficult to flexibly adjust and rearrange. Summary of the invention

[0004] In order to improve the efficiency of disassembly and assembly of the fence, the present application provides a fence.

[0005] The fence provided in this application adopts the following technical solution:

[0006] A fence comprises a plurality of hollow horizontal bars and a plurality of vertical bars, wherein the vertical bars are slidably connected to the horizontal bars, the plurality of the horizontal bars and the plurality of the vertical bars form a grid structure, the vertical bars are rotatably plugged into the horizontal bars, and the sliding connection direction and the plugging direction of the vertical bars form a certain angle for limiting the relative movement of the vertical bars and the horizontal bars.

[0007] By adopting the above technical solution, the installation process is simple and fast, eliminating tedious assembly or welding steps, which can greatly reduce the time and labor cost required for installation. It can be relatively easy to disassemble and move, which is suitable for temporary or movable safety protection needs. It can be flexibly laid out and adjusted according to actual needs, which can meet the needs of different sites and requirements and improve the flexibility of installation; the installation speed is fast and the maintenance cost is low, which can provide better cost-effectiveness overall.

[0008] Optionally, the horizontal bar is provided with a plurality of first mounting holes and a plurality of second mounting holes, and the plurality of first mounting holes and the plurality of second mounting holes are distributed on corresponding sides of the horizontal bar along the length direction of the horizontal bar, and the first mounting holes and the second mounting holes are staggered, and the first mounting holes and the second mounting holes constitute a channel for sliding connection of the vertical bars.

[0009] By adopting the above technical solution, the first mounting hole and the second mounting hole provide a sliding channel for the vertical bar, which reduces the contact area between the horizontal bar and the vertical bar, thereby reducing the friction resistance to the vertical bar, which makes the sliding connection more efficient, and the vertical bar can slide easily and smoothly, while reducing the wear between the vertical bar and the horizontal bar. The first mounting hole and the second mounting hole are staggered, so that the horizontal bar and the vertical bar can slide relative to each other at an acute angle, which helps the operator to control the vertical bar and reduce the vertical bar from sliding too fast and missing the clamping point between the vertical bar and the horizontal bar.

[0010] Optionally, a matching set of the first mounting holes and the second mounting holes partially overlap, the vertical bar is inclined relative to the horizontal bar and is slidably connected to the horizontal bar, and a slot is provided in the circumference of the vertical bar, and the vertical bar is rotatably connected to the horizontal bar through the slot.

[0011] By adopting the above technical solution, the vertical bar rotates with the first mounting hole as the center, the inner wall of the horizontal bar abuts against the inner wall of the slot, and the horizontal bar in the slot supports and limits the vertical bar. Combined with the limiting effect of the first mounting hole on the vertical bar, the horizontal bar and the vertical bar can be quickly assembled into a cross structure; the first mounting hole and the second mounting hole partially overlap, which increases the inclination angle between the vertical bar and the horizontal bar and reduces the situation where the vertical bar is difficult to rotate.

[0012] Optionally, the fence further includes two groups of support rods, both ends of the horizontal rails are plugged into the support rods, the support rods are vertically arranged, and the bottoms of the support rods are connected to support bases for connecting to the ground.

[0013] By adopting the above technical solution, the support rod plays the role of supporting the overall structure, so that the fence can maintain a stable three-dimensional structure, and is connected to the ground through the support seat to play the role of fixing the cross bar, thereby enhancing the overall stability and safety and reducing the risk of the fence tilting, collapsing or moving.

[0014] Optionally, the vertical bar is connected to a hollow limit bar, the limit bar is arranged parallel to the horizontal bar, a plurality of third mounting holes are provided on the side of the limit bar facing the vertical bar, the end of the vertical bar is plugged into the third mounting holes of the limit bar, and the slot of the vertical bar is snap-fitted into the limit bar.

[0015] By adopting the above technical solution, the limit fence can be connected with the slot of the vertical fence to form a grid structure, thereby enhancing the overall strength of the fence. At the same time, the end of the vertical fence can be closed to reduce the risk of scratching people by the end of the vertical fence.

[0016] Optionally, the inner wall of the horizontal bar is provided with a guide member matching with the slot, and the guide member is located on the rotation path of the slot.

[0017] By adopting the above technical solution, the guide can ensure that the slot of the vertical bar can be accurately plugged into the horizontal bar. The guide has an enlarged bottom or edge, which can increase the contact area between the horizontal bar and the vertical bar, and improve the stability and reliability of the plug-in connection.

[0018] Optionally, the cross-section of the guide member is a triangle, and the opening of the slot is a triangle that matches the guide member.

[0019] By adopting the above technical solution, when the guide member and the slot are engaged, the guide member can effectively bear the gravity of the vertical rail and disperse the pressure, thereby increasing the stability of the overall structure, while allowing the horizontal rail to maintain good rigidity and not easily deformed or bent.

[0020] Optionally, the cross-section of the guide member is an arc shape, and the opening of the slot is an arc shape matching the guide member.

[0021] By adopting the above technical solution, when the guide is engaged with the slot, the load is evenly distributed on the guide, reducing the possibility of local stress concentration and improving the stability and safety of the structure. Since the arc-shaped structure has good bending characteristics and rigidity distribution, it can effectively disperse the seismic load, reduce the vibration and stress concentration of the structure, thereby improving the seismic performance of the overall structure.

[0022] Optionally, the fence also includes a guardrail arranged parallel to the crossbar, the guardrail is provided with a plurality of third mounting holes and a plurality of fourth mounting holes, the plurality of third mounting holes and the plurality of fourth mounting holes are correspondingly distributed along the length of the guardrail, and the fourth mounting holes are wider than the third mounting holes along the length direction of the guardrail.

[0023] By adopting the above technical solution, the guardrail and the horizontal rail cooperate with each other to limit the vertical rail, while reducing the installation difficulty when the vertical rail is rotated and improving the installation efficiency.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The installation process is simple and fast, eliminating tedious assembly or welding steps, which can greatly reduce the time and labor costs required for installation and can be relatively easily disassembled and moved;

[0026] 2. It is suitable for temporary or movable security protection needs. It can be flexibly arranged and adjusted according to actual needs, so as to meet the needs of different sites and requirements and improve the flexibility of installation;

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-8 This application is described in further detail.

[0038] The embodiment of the present application discloses a fence.

[0039] Embodiment 1:

[0040] Reference Figure 1 The fence includes at least two support rods 3, and a plurality of horizontal bars 1 are connected between the support rods 3. The horizontal bars 1 are plugged into the support rods 3, so that the support rods 3 play the role of limiting and supporting the horizontal bars 1. The horizontal bars 1 are plugged into a plurality of vertical bars 2. The plurality of vertical bars 2 and the plurality of horizontal bars 1 are plugged and assembled to form a grid-like fence structure, which plays the role of isolation and protection.

[0041] Reference Figure 2 and Figure 3The horizontal rail 1 is a hollow square tube. In other embodiments, the horizontal rail 1 can be a rectangular tube or a circular tube. The horizontal rail 1 is provided with a first mounting side 11 and a second mounting side 12. The first mounting side 11 and the second mounting side 12 are two opposite side walls. The first mounting side 11 is provided with a plurality of first mounting holes 13 along the length direction of the horizontal rail 1. The second mounting side 12 is provided with a plurality of second mounting holes 14 along the length direction of the horizontal rail 1. The first mounting holes 13 and the second mounting holes 14 correspond to each other one by one, forming a group of channels for the vertical rail 2 to be plugged in. The first mounting holes 13 and the second mounting holes 14 are offset along the length direction of the horizontal rail 1, so that the vertical rail 2 is plugged in with the horizontal rail 1 in an inclined state.

[0042] A plurality of slots 21 are provided around the vertical bar 2, and the slots 21 are arranged along the length direction of the vertical bar 2. The vertical bar 2 slides in the channel until the slots 21 and the second mounting hole 14 are located. Under the influence of the gravity of the vertical bar 2, the vertical bar 2 slightly rotates toward the slots 21. The opening of the slots 21 is inclined and abuts against the inner wall of the horizontal bar 1. At this time, the operator can clearly know that this position is the connection point between the horizontal bar 1 and the vertical bar 2. The operator rotates the vertical bar 2 so that the horizontal bar 1 is plugged into the slots 21. When the inner wall of the horizontal bar 1 abuts against the inner wall of the slots 21, the vertical bar 2 is perpendicular to the horizontal bar 1, and the horizontal bar 1 in the slots 21 supports and limits the vertical bar 2.

[0043] It is worth noting that the first mounting hole 13 and the second mounting hole 14 at least partially overlap, so as to ensure that the vertical rail 2 can rotate smoothly and reduce the risk of the vertical rail 2 getting stuck during the rotation process.

[0044] In this embodiment, there are two support rods 3, and the two ends of the horizontal rail 1 are respectively connected to a support rod 3. The support rods 3 are vertically arranged, and the bottom of the support rods 3 is fixedly connected with a support seat 31 for installing the guardrail 5 as a whole on the ground.

[0045] The fence of the present application utilizes its reusable and easy-to-assemble and disassemble characteristics, and compared with traditional fixed fences, it reduces the need for frequent replacement or reconstruction, and reduces the consumption of materials and energy. The fence of the present application is usually made of lightweight, reusable materials, which reduces the consumption of materials and energy, thereby reducing carbon emissions. In addition, due to its recyclable characteristics, it also reduces the carbon emissions generated during the construction or removal of the fence.

[0046] The implementation principle of Example 1 is as follows: the vertical bar 2 is inclined relative to the horizontal bar 1, and is slidably connected to the first mounting hole 13 and the second mounting hole 14 in sequence. When the clamping slot 21 moves to the second mounting hole 14, the operator rotates the vertical bar 2 so that the horizontal bar 1 is clamped with the clamping slot 21, and the vertical bar 2 and the horizontal bar 1 are perpendicular to each other, and the horizontal bar 1 supports the vertical bar 2, so as to achieve the purpose of quick installation.

[0047] Embodiment 2:

[0048] Reference Figure 4 and Figure 5 The difference between this embodiment and the embodiment 1 is that a hollow limiting fence 4 is provided at the end of the vertical fence 2, a third mounting hole 41 is provided on the side of the limiting fence 4 facing the vertical fence 2, and a complete plane is formed on the side of the limiting fence 4 away from the vertical fence 2 to limit the end of the vertical fence 2. The vertical fence 2 is inserted into the limiting fence 4 through the third mounting hole 41, so that the end of the vertical fence 2 is located inside the limiting fence 4, the slot 21 near the top of the vertical fence 2 is engaged with the limiting fence 4, and the two ends of the limiting fence 4 are respectively plugged with a supporting fence.

[0049] Embodiment 3:

[0050] Reference Figure 7 The difference between this embodiment and the first embodiment is that a guide 15 is provided inside the horizontal rail 1, and the guide 15 is fixedly connected to the inner wall of the horizontal rail 1 near the second mounting hole 14. The cross section of the guide 15 is triangular, and the opening of the slot 21 is a triangle that matches the guide 15. When the guide 15 and the slot 21 are engaged, the guide 15 can effectively bear the gravity of the vertical rail 2 and disperse the pressure, thereby increasing the stability of the overall structure, while allowing the horizontal rail 1 to maintain good rigidity and not easily deformed or flexed.

[0051] Embodiment 4:

[0052] Reference Figure 7 The difference between this embodiment and the first embodiment is that the cross section of the guide member 15 is an arc shape, and the opening of the slot 21 is an arc shape that matches the cross section of the guide member 15. When the guide member 15 is engaged with the slot 21, the load is evenly distributed on the guide member 15, reducing the possibility of local stress concentration and improving the stability and safety of the structure. Since the arc-shaped structure has good bending characteristics and rigidity distribution, it can effectively disperse the seismic load, reduce the vibration and stress concentration of the structure, and thus improve the seismic performance of the overall structure.

[0053] Embodiment 5:

[0054] Reference Figure 6The difference between this embodiment and the first embodiment is that a guardrail 5 is further connected between the support rails, and the guardrail 5 is provided with a fourth mounting hole 51 and a fifth mounting hole 52, which are located on the corresponding sides of the guardrail 5, and the fourth mounting hole 51 and the fifth mounting hole 52 constitute a channel for the vertical rail 2 to slide. In this embodiment, the fourth mounting hole 51 and the fifth mounting hole 52 are both square holes, and the fifth mounting hole 52 is wider than the fourth mounting hole 51 along the length direction of the guardrail 5, and the range of the fourth mounting hole 51 in the vertical direction is located within the range of the fifth mounting hole 52, providing space for the vertical rail 2 to rotate. The horizontal rail 1 and the guardrail 5 cooperate to achieve the rapid loading and unloading of the vertical rail 2, and can play a good limiting role.

[0055] Embodiment 6:

[0056] Reference Figure 8 The difference between this embodiment and embodiment 1 is that the horizontal bar 1 is provided with a clamping block 6, and the clamping block 6 is clamped in the gap between the vertical bar 2 and the second positioning hole to limit the vertical bar 2.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
