[0024] The safety fence comprises a vertical isolation fence 1 and an anti-push-over seat 2.
[0025] The vertical isolation fence 1 is arranged vertically, and the anti-pushing seat 2 is arranged horizontally.
[0026] The bottom of the vertical isolation fence 1 is fixed to the middle of the anti-push-over seat 2, dividing the anti-push-over seat 2 into a first anti-push-over seat part 11 and a second anti-push-over seat part 12. The first anti-push-over seat part 11 is located on the right side of the vertical isolation fence 1, and the second anti-push-over seat part 12 is located on the left side of the vertical isolation fence 1.
[0027] At least one connecting hook 5 is fixed to the first column 3 on one side of the vertical isolation fence 1 , and at least one connecting ring 6 is fixed to the second column 4 on the other side of the vertical isolation fence 1 .
[0028] The connection hooks 5 and the connection rings 6 are located in corresponding positions and are the same in number. In this embodiment, each safety fence has two connection hooks 5 and two connection rings 6 .
[0029] The vertical isolation fence 1 includes a first column 3 , a second column 4 , a plurality of cross bars 10 and a plurality of connecting bars 7 .
[0030] The upper part of the first column 3 and the upper part of the second column 4 are fixedly connected by two cross bars 10 .
[0031] The lower middle portion of the first column 3 and the lower middle portion of the second column 4 are fixedly connected via a cross bar 10 .
[0032] A plurality of connecting rods 7 arranged vertically in parallel are fixed between the lower crossbar 10 and an upper crossbar 10 .
[0033] The bottom of the first column 3 and the bottom of the second column 4 are fixed (welded) to the frame of the anti-push-over seat 2 .
[0034] The frame of the anti-pushing-down seat 2 is a trapezoid or a triangle.
[0035] A plurality of forward rods 9 are fixed along the length direction in the anti-pushing down seat frame. In the present embodiment, there are three forward rods 9.
[0036] When the frame of the anti-pushing-down seat 2 is a trapezoid, the lower base is on the right side, and a plurality of forward rods 9 are arranged parallel to the upper base and the lower base of the trapezoid.
[0037] The bottom of the vertical isolation fence 1 is fixed at the right one-fifth of the width direction of the anti-push-over seat 2.
[0038] When the frame of the anti-pushing seat 2 is a triangle, a plurality of forward rods 9 are arranged parallel to one side of the right side of the triangle.
[0039] The bottom of the vertical isolation fence 1 is fixed at the right one-fifth of the width direction of the anti-push-over seat 2.
[0040] That is, the bottom of the vertical isolation fence 1 is fixed at a position close to one-fifth of the length of the anti-push-over seat 2.
[0041] The width of the first portion 11 of the anti-push-over seat is smaller than the width of the second portion 12 of the anti-push-over seat.
[0042] The connecting ring 6 is a long round hollow tube (steel tube). The connecting hook 5 is an L-shaped hook in the downward direction.
[0043] Furthermore, in order to prevent the connecting hook 5 and the connecting ring 6 from being easily disassembled, the vertical side of the connecting hook 5 has a head 8 bent inwardly to ensure that it cannot be easily disassembled after being inserted into the connecting ring 6. The horizontal side of the connecting hook 5 is fixed to the first column 3.
[0044] The usage is:
[0045] When installing and using, put the anti-push-over seat 2 on the ground, install the connecting ring 6 and the connecting hook 5 accordingly, and pull it forward. Each section can be extended according to the needs. The second part 12 of the anti-push-over seat faces the crowd, and the vertical isolation fence 1 and the anti-push-over seat 2 are fixed with asymmetric nodes. The second part 12 of the anti-push-over seat is stepped on by the weight of the onlookers' feet, and there is no way to push down and open the guardrail. The more people there are, the less likely the fence is to be pushed down and opened. In addition, the connecting ring 6 hooks the connecting hook 5 to have an angular range of motion, and the overall long fence can be bent and deformed, which solves the problem of requiring a large number of security personnel to push outward from the inside to prevent the fence from being pushed down.
