[0002] Construction site safety warning signs are one of the indispensable safety facilities in construction. Their main function is to remind workers and pedestrians to pay attention to safety issues on the construction site and avoid accidental injuries. Warning signs are usually set up in conspicuous locations on the construction site, such as at the gate, on the wall, etc. They can include different types of warnings, such as high-altitude operations, electrical equipment, dangerous areas, etc.

[0003] Most of the commonly used safety warning signs currently in use are of a foldable unfolding structure, which is practical and convenient and can be quickly unfolded and supported. However, the supporting angle is not adjustable and the sign will still rotate after being folded, which reduces its stability after being folded. In addition, during the process of holding the sign, the hand will be clamped due to the rotation of the two support rods, which reduces its carrying safety. At the same time, the bottom of the sign does not have an adjustment function, which reduces its adaptability for use on uneven ground. Utility Model Content

[0025] The guide plate 7 is fixedly connected to the side of the first vertical pole 1 that is close to each other, and a guide shaft 10 passes through the inside of the guide plate 7, an adjusting plate 9 is fixedly connected to the bottom of the guide shaft 10, a positioning rod 91 is arranged at the bottom of the adjusting plate 9, an adjusting wheel 13 is fixedly connected to one end of the rotating shaft 12, and the positioning rod 91 is inserted into the inside of the adjusting wheel 13. Through the arrangement of this structure, when the adjusting plate 9 drives the positioning rod 91 to be pulled up, the engagement with the adjusting wheel 13 is released, thereby realizing the angular rotation of the first vertical pole 1 and the second vertical pole 2. Conversely, when the two are inserted into each other, the rotation of the adjusting wheel 13 is restricted, so that the second vertical pole 2 and the first vertical pole 1 cannot rotate, thereby achieving a good positioning effect.

[0026] Preferably, two first upright poles 1 and two second upright poles 2 are provided, and a reinforcing rod 4 is fixedly connected between the two first upright poles 1 and between the two second upright poles 2, and the reinforcing rod 4 plays a role of reinforcing support.

[0027] Preferably, threaded holes are provided at the bottom centers of the first upright pole 1 and the second upright pole 2, and the internal threads of the threaded holes are connected to threaded feet 5, and anti-slip pads are provided at the bottoms of the threaded feet 5. Through the setting of this structure, the adaptive adjustment of the support height can be achieved, thereby meeting the corresponding adjustment under uneven ground conditions and ensuring the stability of the device support.

The handle 8 is in a U-shaped structure, and both ends of the handle 8 pass through the guide plate 7 and are fixedly connected to the upper surface of the adjustment plate 9. With the assistance of the control rod 6, it is convenient to carry out traction control on the handle 8. By holding the control rod 6 and the handle 8, the handle 8 can be pulled upward, thereby driving the adjustment plate 9 to move upward and releasing the engaged state.

[0029] Preferably, two guide shafts 10 are passed through the interior of each guide plate 7 , and a return spring 11 is sleeved on the exterior of the guide shaft 10 , and the return spring 11 abuts between the guide plate 7 and the adjustment plate 9 .

[0030] Preferably, two groups of guide plates 7, adjustment plates 9, guide shafts 10, return springs 11, rotating shafts 12 and adjustment wheels 13 are provided, and the two groups of guide plates 7, adjustment plates 9, guide shafts 10, return springs 11, rotating shafts 12 and adjustment wheels 13 are symmetrically distributed at both ends of the handle 8. Through the symmetrical distribution on both sides, both sides can achieve snap-in positioning, thereby ensuring the stability of its positioning support.

[0032] Working principle: the first upright pole 1, the second upright pole 2 and the warning plate 3 used in the present application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here. When the present invention is in use, first hold the control rod 6 and the handle 8, and pull the handle 8 upward, so that the adjustment plate 9 moves up with it, and then releases the engagement of the positioning rod 91 with the adjustment wheel 13. At this time, the angle of the first upright pole 1 and the second upright pole 2 is rotated. After adjusting to the appropriate angle, loosen the handle 8, and the adjustment plate 9 is affected by the elasticity of the return spring 11, so that the positioning rod 91 is inserted into the inside of the adjustment wheel 13, thereby completing the limit engagement of the first upright pole 1 and the second upright pole 2 to prevent the two from rotating.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
