Description

Technical Field

[0001] The utility model relates to the technical field of construction fences, in particular to a construction safety fence. Background Art

[0002] During construction, to prevent others from mistakenly entering the construction area, it is necessary to put up a construction fence in the construction area to remind others that construction is in progress and serve as a good warning. Especially during road construction, the construction area needs to be fenced off in time to prevent pedestrians or vehicles from mistakenly entering;

[0003] However, the safety fences in the prior art are usually assembled by assembling single guardrails, resulting in that after each switch of the road construction area, several guardrails need to be disassembled at the previous construction site and transferred to the switched construction area for assembly. The operation is cumbersome, which reduces the construction efficiency, and it is difficult to transport the several guardrails that are disassembled into a single state each time.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Utility Model Content

[0005] The purpose of the utility model is to provide a construction safety fence to solve the problems in the above background technology that the existing construction safety fence has a complicated assembly process, reduces construction efficiency, and is not conducive to transportation.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-6 , the utility model provides a technical solution:

[0037] A construction safety fence includes a first guardrail 100, second guardrails 101 provided on both sides of the first guardrail 100, and further includes:

[0038] The folding unit 1 includes a bearing assembly 12 for supporting the bottom of the first guardrail 100 and the second guardrail 101, and a clamping assembly 11 provided inside the bearing assembly 12 for clamping the first guardrail 100 and the second guardrail 101;

[0039] The limiting unit 2 is provided at the connection between the first guardrail 100 and the second guardrail 101 and is used to limit the first guardrail 100 and the second guardrail 101 during the folding process.

[0040] As an improvement, Figure 4-5 As shown, one side of the first guardrail 100 is provided with a first plug shaft 1001 fixedly connected to be plugged into the inside of the bearing assembly 12, and a first outer circular groove 1002 is provided outside the first plug shaft 1001 and inside the bearing assembly 12;

[0041] A second plug-in shaft 1011 for plugging into the interior of the support is fixedly connected to one side of the second guardrail 101 , and a second outer circular groove 1012 is provided outside the second plug-in shaft 1011 and inside the support assembly 12 .

[0042] Furthermore, the bearing assembly 12 includes:

[0043] The fixing block 121 is provided directly below the first plug shaft 1001 and the second plug shaft 1011;

[0044] There are two groups of insertion holes 123 at the upper end of the fixed block 121, which are used to accommodate the lower parts of the first insertion shaft 1001 and the second insertion shaft 1011 respectively;

[0045] The first plug shaft 1001 and the second plug shaft 1011 can both rotate inside the plug hole 123 .

[0046] Preferably, a mounting hole 122 is provided inside the fixing block 121 from top to bottom, for fixing the fixing block 121 by driving a screw into the ground through the mounting hole 122;

[0047] Furthermore, if Figure 2 , Figure 5 As shown, the clamping assembly 11 includes:

[0048] The insertion rod 111 is slidably inserted into the interior of the fixing block 121;

[0049] The guide groove 112 extends from the interior of the fixing block 121 on one side of the fixing block 121 and is used to guide the movement of the insertion rod 111 .

[0050] The guide groove 112 is connected to the two groups of the insertion holes 123;

[0051] One side of the insertion rod 111 is located in the first outer circular groove 1002 and the second outer circular groove 1012 , and is used to clamp and limit the first insertion shaft 1001 and the second insertion shaft 1011 .

[0052] As an improvement, Figure 2-3 As shown, the limiting unit 2 includes:

[0053] There are two groups of clips 21, which are respectively located on both sides of the first plug shaft 1001 and the second plug shaft 1011, and are used to bind the first plug shaft 1001 and the second plug shaft 1011;

[0054] The arc-shaped clamping groove 22 is provided at both ends of the clamping piece 21, and is used to accommodate the first plug-in shaft 1001 and the second plug-in shaft 1011 respectively. The arc-shaped clamping groove 22 is rotatably connected to the first plug-in shaft 1001 and the second plug-in shaft 1011;

[0055] The fastening bolt 23 is inserted between the two sets of clips 21;

[0056] The fastening nut 24 is threadedly connected to the fastening bolt 23 and is used to fasten the two sets of clips 21.

[0057] It should be noted that the present invention is described by taking the folding process of three groups of guardrails as an example.

[0058] It should be noted that: in the specific implementation process of this utility model, Figure 1-3 , Figure 6 As shown, when the fence is needed at the construction site, the fence in the folded state is placed on the construction site, so that the fixing block 121 is placed on the ground, the first guardrail 100 and the second guardrail 101 are in the upright state, and then the second guardrails 101 on both sides of the first guardrail 100 are pulled apart. During this process, the second guardrail 101 drives the second plug shaft 1011 to rotate in the plug hole 123, and the second plug shaft 1011 also rotates relative to the arc-shaped clamping groove 22, so that the fence in the folded state can be quickly switched to the U-shaped fence, thereby eliminating the need to assemble the single-state guardrail at the construction site, simplifying the operation, and improving the overall construction efficiency.

[0059] Similarly, when the U-shaped fence needs to be folded after each use, it is only necessary to pull the second guardrail 101 in the opposite direction so that the second guardrail 101 rotates toward the first guardrail 100 until it is close to the first guardrail 100 to complete the folding work, which is convenient for subsequent transportation of the safety fence.

[0060] like Figure 2 , Figure 4-5 As shown, in addition, the utility model inserts the insertion rod 111 into the guide groove 112 so that one side of the insertion rod 111 is located inside the first outer circular groove 1002 and the second outer circular groove 1012 respectively, so that when the first insertion shaft 1001 and the second insertion shaft 1011 are rotated and adjusted during the folding process, the insertion rod 111 can lock the first insertion shaft 1001 and the second insertion shaft 1011 inside the fixed block 121 to prevent the first insertion shaft 1001 and the second insertion shaft 1011 from falling off from the fixed block 121, thereby improving the overall reliability of the fence.
