A good safety facility system should have multiple functions such as traffic management, safety protection, traffic guidance, isolation and closure, and anti-glare. Road construction signs are a type of road safety equipment. Construction road barriers are also known as construction signs, construction signs, and movable signs. They are used for peripheral protection prompts at road construction sites, maintenance of municipal construction, and construction. They can be placed wherever needed to guide traffic at any time to prevent accidental collisions and reduce losses.

[0003] Construction warning signs are used in a wide range of scenarios, such as roads, walls, fences, etc. The current construction warning signs have a simple structure, and each warning sign can only be installed in a specific location.

On a relatively flat road surface, this type of warning device is relatively stable. However, on an inclined road surface, the pole-type warning device is easily affected by wind and sand and is prone to tipping over. Therefore, there is an urgent need for a construction warning device that can adapt to a variety of complex environments to solve the current problems. Utility Model Content

The circular groove 5 is opened at the lower end of the first rotating rod 3. The circular groove 5 is coaxially arranged with the rotating shaft 4. The side wall of the circular groove 5 is along the circumference. A plurality of slots 6 are evenly arranged in the direction, the plug-in shaft 7 is fixedly connected to the upper end of the support rod 2, the plug-in shaft 7 is coaxially inserted in the circular groove 5, and a plurality of spherical protrusions 8 are evenly connected to the outer side of the plug-in shaft 7 along the circumferential direction, the spherical protrusions 8 correspond to the slots 6 one by one, the spherical protrusions 8 cooperate with the slots 6, the second rotating rod 9 is rotatably connected to the upper end of the first rotating rod 3, the rotational connection method of the second rotating rod 9 is the same as the rotational connection method of the lower end of the first rotating rod 3, and the warning sign 1 is detachably connected to the upper end of the second rotating rod 9.

[0021] The utility model enables the rod-type warning device to be rotatably adjusted through the first rotating rod 3 and the second rotating rod 9. The warning sign 1 is connected to the second rotating rod 9. When used on a relatively flat ground, the first rotating rod 3 and the second rotating rod 9 are rotated so that the three rods are in a coaxial state, and the spherical protrusion 8 is engaged through the card slot 6, so that the warning device can be stably placed on a flat road surface. When used on an inclined ground, the first rotating rod 3 and the second rotating rod 9 can be rotated to adjust the position of the warning sign 1, and then the center of gravity of the entire device can be adjusted, so that the device can be stably placed on the inclined ground, and the first rotating rod 3 and the second rotating rod 9 can be rotated to adjust the angle of the warning sign 1, so that the device has the advantages of multi-function, good adaptability and easy operation.

[0022] Specifically, it also includes a fixed seat 10, two clamping members 11, a bidirectional screw rod 12, an adjusting knob 13, a sleeve 14 and a spring rod 15. One side of the fixed seat 10 is connected to the warning sign 1. The two clamping members 11 are respectively slidably connected to the two sides of the fixed seat 10. The second rotating rod 9 is clamped between the two clamping members 11. The bidirectional screw rod 12 is rotatably connected to one side of the fixed seat 10. The two ends of the bidirectional screw rod 12 respectively pass through the two clamping members 11. The clamping member 11 is threadedly connected to the bidirectional screw rod 12. The adjusting knob 13 is fixedly connected to one end of the bidirectional screw rod 12. The sleeve 14 is sleeved on the middle part of the bidirectional screw rod 12. The sleeve 14 is rotatably connected to the bidirectional screw rod 12. The spring rod 15 passes through the fixed seat 10. The spring rod 15 is slidably connected to the fixed seat 10. One end of the spring rod 15 is fixedly connected to the sleeve 14, and the other end of the spring rod 15 abuts against the second rotating rod 9.

[0023] In the above embodiments, the bidirectional screw rod 12 is rotated by rotating the adjusting knob 13, thereby realizing the operation of the two clamping members 11 moving closer to or farther away from each other, thereby quickly fixing the warning sign 1 on the second rotating rod 9, and conveniently and quickly disassembling it. In some specific scenarios, the second rotating rod 9 and other rods can be disassembled, and the warning sign 1 can be fixed on other rods, such as street lights, road fences, etc., to further improve the practicality and versatility of the device. The spring rod 15 abuts against the second rotating rod 9 to further improve its stability.

[0024] Specifically, it also includes a pushing ring 16, multiple side rods 17 and multiple driving rods 18. The pushing ring 16 is sleeved on the support rod 2. The pushing ring 16 is slidably connected to the support rod 2. The multiple side rods 17 are evenly hinged to the pushing ring 16 along the circumferential direction. The multiple driving rods 18 correspond to the side rods 17 one by one. The first end of the driving rod 18 is hinged to the lower end of the support rod 2, and the second end of the driving rod 18 is hinged to the side rod 17.

[0025] In the above embodiments, after the push ring 16 slides, due to the action of the driving rod 18, the side rod 17 is stretched outward to form a stable lateral support, which is convenient for the support rod 2 to stand on the ground, and the structure is convenient to fold and shrink, and is easy to carry.

[0026] Specifically, it also includes: the screw rod 19 is fixedly connected to one side of the fixing seat 10 , the screw rod 19 is screwed into the warning sign 1 , and the warning sign 1 is detachably connected to the fixing seat 10 via the screw rod 19 .

[0027] In the above embodiments, the screw connection method facilitates the disassembly of the fixing base 10, so that the warning sign 1 can be nailed to a wall or other location, further improving the versatility and applicability of the device.

[0028] Specifically, it also includes: two elastic members 20 corresponding to the clamping members 11 one by one, and the elastic members 20 are connected to the inner side of the clamping members 11 .

[0029] In the above embodiments, the elastic member 20 is made of a material with a relatively large friction force, so as to be stably clamped on the rod.

[0030] The working principle of the utility model is as follows: when used on an ordinary relatively flat road surface, the first rotating rod 3 and the second rotating rod 9 can be rotated to make the support rod 2, the first rotating rod 3, and the second rotating rod 9 coaxial, so that the push ring 16 slides on the support rod 2, and the push ring 16 forms a connecting rod structure with the side rod 17 and the driving rod 18. The multiple side rods 17 are opened outward, and the side rods 17 provide reliable lateral support force for the support rod 2, so that the device can be stably erected on the ground;

[0031] When used on an inclined ground, the first rotating rod 3 and the second rotating rod 9 are rotated, and the plug-in shaft 7 rotates in the circular groove, and the spherical protrusion 8 on the plug-in shaft 7 moves in different slots 6. After the angle adjustment is completed, the spherical protrusion 8 is stably engaged in the slot 6, thereby fixing the first rotating rod 3 and the second rotating rod 9. The adjusted first rotating rod 3 and the second rotating rod 9 not only facilitate the adjustment of the position of the warning sign 1, but also adjust the center of gravity of the device, thereby enabling the device to be relatively stably erected on an inclined ground.

[0032] When installing on other poles, such as street lights and fences, the adjusting knob 13 can be rotated to rotate the bidirectional screw rod 12, thereby making the two clamping members 11 approach each other, and the warning sign 1 can be installed on other poles;

[0033] When installing on a wall, the fixing base 10 can be rotated to remove the entire clamped component and nail the warning sign 1 to the wall.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
