Preferably, fuma wheels 202 are provided at the bottom of both ends of the stabilizing support plate 201.

[0030] Please see the appendix Figure 4 and attached Figure 5 The basic guardrail 1 includes several vertical bars and horizontal bars vertically connected to the top and bottom of the several vertical bars; the lifting guardrail 3 includes several vertical bars and horizontal bars vertically connected to the top of the several vertical bars, and the several vertical bars of the lifting guardrail 3 are respectively inserted into the several vertical bars of the basic guardrail 1; the height adjustment structure 4 is set in the vertical bars of the basic guardrail 1 and connected to the vertical bars of the lifting guardrail 3, so that the vertical bars of the lifting guardrail 3 and the vertical bars of the basic guardrail 1 can be inserted into each other in a lifting manner; the synchronous adjustment structure 6 is set in the horizontal bars of the lifting guardrail 3.

[0031] Preferably, the vertical and horizontal bars of the basic guardrail 1 and the vertical and horizontal bars of the lifting guardrail 3 can be made of square steel tubes and welded into a whole. The size and specifications of the square steel tubes of the lifting guardrail 3 and the size and specifications of the square steel tubes of the basic guardrail 1 can be adapted to the actual use requirements. The size of the vertical bar of the lifting guardrail 3 is one size smaller than the size of the vertical bar of the basic guardrail 1 to ensure the insertion and lifting function of the vertical bar of the lifting guardrail 3 within the vertical bar of the basic guardrail 1.

[0032] Please see the appendix Figure 5 The height adjustment structure 4 includes a linkage bevel gear 401, a height adjustment threaded rod 402, and a height adjustment bevel gear 403.

[0033] Preferably, the linkage bevel gear 401 and the height adjustment bevel gear 403 can be 45° bevel gears. The height adjustment bevel gear 403 can be rotated clockwise or counterclockwise in the vertical plane by a knob, thereby engaging and driving the linkage bevel gear 401 to rotate clockwise or counterclockwise in the horizontal plane, and simultaneously driving the height adjustment threaded rod 402 to rotate synchronously.

[0034] Since the vertical bars of the lifting guardrail 3 and the basic guardrail 1 are made of square steel pipes, the shape restriction prevents the vertical bars of the lifting guardrail 3 from rotating within the vertical bars of the basic guardrail 1. Thus, the rotation of the height adjustment thread rod 402 can be converted into linear movement of the vertical bars of the lifting guardrail 3 along the axial direction of the height adjustment thread rod 402 under the transmission of the thread, thereby achieving the lifting adjustment function of the lifting guardrail 3.

[0035] Preferably, a height adjustment structure 4 can be installed in the vertical bar on one side or both sides of the vertical bar of the lifting guardrail 3 and the basic guardrail 1, so as to facilitate stable lifting and lowering adjustment control of the lifting guardrail 3.

The two ends of the synchronous adjustment screw 603 are rotatably mounted in the crossbar of the lifting guardrail 3 via rotary bearings. The driven bevel gear 604 is coaxially fixed to the synchronous adjustment screw 603. A mounting hole is formed on the crossbar of the lifting guardrail 3, allowing the adjustment bevel gear 605 to be rotatably fitted into the mounting hole. The bevel gear surface of the adjustment bevel gear 605 meshes and drives with the driven bevel gear 604. The top of the adjustment bevel gear 605... A knob is provided above the crossbar of the lifting guardrail 3; one end of the adjusting slider 602 has a threaded hole that matches the synchronous adjusting screw 603, so that one end of the adjusting slider 602 is screwed onto the synchronous adjusting screw 603 through thread matching, and the other end of the adjusting slider 602 is rotatably connected to one end of the support adjusting plate 601 through a rotating shaft, and the other end of the support adjusting plate 601 is rotatably connected to the middle of the anti-tipping blade 5 through a rotating shaft, so that the anti-tipping blade 5 is vertically set on the crossbar of the lifting guardrail 3 or horizontally attached to the crossbar of the lifting guardrail 3 through the support adjusting plate 601.

[0037] Preferably, the driven bevel gear 604 and the adjusting bevel gear 605 can be 45° bevel gears. The adjusting bevel gear 605 can be controlled by a knob to rotate clockwise or counterclockwise in the horizontal plane, which can mesh with and drive the driven bevel gear 604 to rotate clockwise or counterclockwise in the vertical plane, and drive the synchronous adjusting screw 603 to rotate synchronously.

[0038] Preferably, the adjusting slider 602 can adopt a Z-shaped structure, with both ends of the adjusting slider 602 being rectangular blocks, so that it can move within the square steel tube, i.e., the crossbar, of the lifting guardrail 3, and is restricted to rotating within the crossbar. During the rotation of the synchronous adjusting screw 603, the rotation of the synchronous adjusting screw 603 can be converted into linear motion of the adjusting slider 602 along the axis of the synchronous adjusting screw 603 by using thread transmission, thereby pushing the anti-tipping blade 5 through the support adjusting plate 601, causing the anti-tipping blade 5 to flip between 0° and 90°.

[0039] Preferably, the number of anti-tipping blades 5 and their spacing can be adjusted according to actual usage requirements, the length of the anti-tipping blades 5 and the length of the crossbar of the lifting guardrail 3. The number of support adjustment plates 601 and adjustment sliders 602 is the same as the number of anti-tipping blades 5, so that when the synchronous adjustment screw 603 rotates, it can synchronously drive all the anti-tipping blades 5 on it to rotate synchronously.

[0040] Please see the appendix Figure 1 To be continued Figure 6 The method of use and working principle of this utility model are as follows:

[0041] The folded safety fence is moved to the location requiring protection using the fenders 202. The individual fence units are unfolded by rotating the hinges; the hinges can be rotated to the appropriate angle according to the boundary of the protected area, allowing each fence unit to be set up along the boundary. After installation, the fenders 202 are locked to ensure the stability of the safety fence. If necessary, the safety fence can be reinforced to the ground using bolts, posts, etc.

[0042] Depending on the required height of protection, the height adjustment bevel gear 403 is turned by rotating the knob, causing the height adjustment bevel gear 403 to engage with the linkage bevel gear 401. The linkage bevel gear 401 drives the height adjustment threaded rod 402 to rotate synchronously. The threaded transmission adjusts the vertical bar of the lifting guardrail 3, causing it to move up or down relative to the vertical bar of the basic guardrail 1, thereby adjusting the protection height of the safety guardrail, preventing it from being climbed over, and improving the protection effect.

[0043] Meanwhile, the bevel gear 605 can be adjusted by rotating the knob, which engages with the driven bevel gear 604, causing the driven bevel gear 604 to drive the synchronous adjusting screw 603 to rotate. The screw drive causes the adjusting slider 602 to move linearly along the axis of the synchronous adjusting screw 603. The adjusting slider 602 moves towards the anti-overturning blade 5, so that the support adjusting plate 601 supports the anti-overturning blade 5 to a certain angle, so that it is set vertically or obliquely on the top of the horizontal bar of the lifting guardrail 3, preventing it from being overturned and enhancing the protective effect.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
