[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Embodiment 1

[0041] See also Figure 1-5 A temporary guardrail for a high-rise building comprises a main body component 1, wherein the main body component 1 comprises: a pillar 11, at the bottom of which a wheel 12 is symmetrically arranged; a folding component 2 is arranged on the pillar 11, and the folding component 2 comprises: a cavity 21, arranged inside the pillar 11; a bidirectional screw rod 22, rotatably connected to the inside of the cavity 21; a hand wheel 23, rotatably connected to the top of the pillar 11 on the left side, the hand wheel 23 penetrates and extends into the inside of the cavity 21, and the hand wheel 23 is fixedly connected to the bidirectional screw rod 22; a threaded block 24, symmetrically and threadedly connected to the bidirectional screw rod 22; a sliding rod 26, fixedly connected to the pillar 11 on the right side, the threaded block 24 is symmetrically arranged in two groups, and the threaded block 24 on the right side is slidably connected to the sliding rod 26; a cross telescopic frame 25, hinged between the threaded blocks 24. A telescopic rod 27 is fixedly connected between the pillars 11, and a telescopic shell 251 is fixedly connected between the pillars 11. The telescopic shell 251 is sleeved on the cross telescopic frame 25 and the outside of the telescopic rod 27. A connecting sleeve 13 is fixedly connected to the left wall of the left pillar 11, and a connecting rod 14 is fixedly connected to the right wall of the right pillar 11. The through hole on the connecting sleeve 13 is adapted to the connecting rod 14.

[0042] When in use, the staff uses the wheels 12 to move the pillars 11 to the high-rise building that needs to be protected, and uses the folding component 2 to adjust the spacing of the pillars 11 to adapt to different work scenarios: the staff turns the hand wheel 23, and the hand wheel 23 drives the bidirectional screw rod 22 to rotate. The two threaded blocks 24 threadedly connected on the bidirectional screw rod 22 approach each other or move away from each other as the bidirectional screw rod 22 rotates in different directions. The moving direction and distance of the threaded blocks 24 are controlled by the rotation direction and number of rotations of the bidirectional screw rod 22. When the threaded blocks 24 approach each other, the left ends of the cross telescopic frame 25 hinged thereon approach each other, so that the cross telescopic frame 25 extends to the right. At this time, the two threaded blocks 24 on the right slide on the sliding rod 26. When the cross telescopic frame 25 is extended, the spacing between the two pillars 11 becomes larger, and the enclosed distance is longer. Conversely, when the threaded blocks 24 move away from each other, the cross telescopic frame 25 contracts, which occupies a smaller area and improves the convenience of carrying the device. The telescopic rod 27 is telescopically extended and retracted along with the cross telescopic frame 25, improving the stability when the spacing between the pillars 11 changes. The telescopic shell 251 shields and protects the cross telescopic frame 25 and the telescopic rod 27, preventing the cross telescopic frame 25 and the telescopic rod 27 from entering the fluff and other debris during the telescopic process, which affects the telescopic state. At the same time, the telescopic shell 251 increases the enclosure area between the pillars 11, enhancing the protection effect. When the cross telescopic frame 25 is extended to the longest distance, and the spacing between the pillars 11 still cannot meet the shielding requirements, the staff can insert the connecting rod 14 on the right side of the other group of pillars 11 into the connecting sleeve 13 on the left side of the current group of pillars 11 to complete the connection between the two groups of pillars 11, thereby increasing the shielding area.

[0043] Embodiment 2

[0044] On the basis of the mobile implementation example, an auxiliary function is added.

[0045] See also Figure 1-5 , a support assembly 3 is provided at the bottom of the pillar 11, and the support assembly 3 includes: a second cavity 31, which is opened inside the pillar 11, and the second cavity 31 is located below the first cavity 21; a micro motor 32, which is fixedly connected to the top surface of the second cavity 31; a screw rod 33, which is rotatably connected to the second cavity 31, and the top of the screw rod 33 is fixedly connected to the output shaft of the micro motor 32; a support seat 34, which is threadedly connected to the outside of the screw rod 33; a slider 35, which is symmetrically arranged on both sides of the support seat 34; a slide groove 36, which is symmetrically opened on the two side walls of the second cavity 31, and the slider 35 is slidably connected to the slide groove 36. The two pillars 11 are provided with support assemblies 3, and the front side wall of the second cavity 31 on the left is provided with a switch 37, and the switch 37 is electrically connected to the two micro motors 32. The support seat 34 is prism-shaped.

[0046] When the wheel 12 moves to a suitable place, the support assembly 3 supports the pillar 11 to prevent the pillar 11 from moving: start the micro motor 32, the micro motor 32 drives the screw rod 33 to rotate, and the support seat 34 threadedly connected to the screw rod 33 moves downward, extending the pillar 11 until the support seat 34 contacts the ground, preventing the wheel 12 from driving the pillar 11 to move. When the support seat 34 moves, the sliders 35 on both sides slide in the slide groove 36. The sliders 35 increase the stability of the support seat 34 when it moves, and prevent the support seat 34 from rotating with the screw rod 33, thereby losing the moving effect. When the pillar 11 needs to be moved, the micro motor 32 is rotated in the opposite direction, so that the screw rod 33 is reversed, and the support seat 34 is retracted into the cavity 2 31, and the wheel 12 can drive the pillar 11 to move. When the staff needs to use the support assembly 3, they can touch the switch 37 at the bottom with their feet. The switch 37 controls the opening and closing of the power supply of the micro motor 32, which improves the convenience of use for the staff. The prism-shaped support base 34 increases its contact area with the bottom surface, and has a better supporting effect than the square support base 34 .
