[0002] Triangular signs are a common type of traffic sign, mainly used for warnings and instructions. They are divided into warning signs and yield signs. The former are mostly equilateral triangles with black patterns on a yellow background, reminding drivers to pay attention to potential dangers ahead, such as sharp turns or construction areas; the latter are inverted triangles with red edges on a white background, indicating that vehicles need to yield when entering the main road. These signs improve road safety and ensure smooth traffic through clear and visible designs.

[0003] In the prior art, most triangular signboards are directly fixed on the ground through pillars. On some county roads or provincial roads, large and extra-wide trucks carrying goods or grass passing through the road sections will rub against the road signs, causing the signs to deform and be damaged, thereby causing safety hazards and economic losses. Summary of the invention

[0004] The purpose of the utility model is to solve the problem that in the prior art, most triangular signboards are directly fixed on the ground by columns. On some county roads or provincial roads, large and extra-wide trucks pulling goods or grass passing through the road sections will rub against the road signboards, causing the signboards to deform and be damaged, thereby causing safety hazards and economic losses. The foldable and resilient signboard is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A foldable and resilient signboard comprises a supporting base 2, a fixing plate 11, a right-angled triangle sign 7 and an inverted U rod 3. A column 1 is fixedly arranged on the top of the supporting base 2, a fixing plate 11 is fixedly arranged on the top of the column 1, a receiving groove 8 is opened at the center position of the top of the fixing plate 11, and threaded holes 12 are opened on both sides of the receiving groove 8 of the fixing plate 11. A rotating column 5 is symmetrically and movably inserted into the top of the inverted U rod 3, and a right-angled triangle sign 7 is fixedly arranged on the top of the rotating column 5. Avoidance arc surfaces 71 are arranged at the contact positions of the two groups of right-angled triangle signs 7 to prevent one of the two groups of right-angled triangle signs 7 from being obstructed when rotating.

[0021] The bottom of the right-angle triangle sign 7 is provided with a rebound folding assembly at one end away from the rotating column 5 to reduce the damage of the sign to the super-wide train. The two ends of the inverted U rod 3 are screwed with middle bolts 31, which are screwed into the threaded hole 12. The bottom of the inverted U rod 3 is provided with a mounting groove 32.

[0022] A limit ring 4 is fixed at the bottom of the rotating column 5 by bolts. The diameter of the limit ring 4 is larger than the diameter of the rotating column 5. The limit ring 4 and the rotating column 5 extend into the accommodating groove 8. The setting of the limit ring 4 allows the right-angled triangle 7 on the top of the rotating column 5 to rotate stably around the top of the inverted U rod 3.

[0023] The rebound folding component includes a rebound column 6 and a return spring 9. The rebound column 6 is fixedly arranged at one end of the bottom of the right-angled triangle 7 away from the rotating column 5. An arc groove 10 is symmetrically opened on the top of the fixed plate 11. The diameter of the rebound column 6 is the same as the width of the arc groove 10. Return springs 9 are fixedly arranged on both sides of the arc groove 10. The end of the rebound column 6 extends into the gap between the two groups of return springs 9. There is a reinforcing rib 21 in a circular array on the top of the support base 2. The side of the reinforcing rib 21 is fixedly arranged on the side wall of the column 1, thereby improving the connection strength between the support base 2 and the column 1.

[0024] It should be supplemented that the two right-angled triangle signs 7 form a complete triangular sign board, and the logo of the triangular sign board is divided and sprayed on the sides of the two right-angled triangle signs 7.

[0025] The specific implementation steps and principles of the utility model are as follows:

[0026] When the entire triangular sign is in a normal state, the two right-angled triangles 7 are in a flush state, and the return springs 9 at both ends of the rebound column 6 are in an original length state. When a vehicle from the front or rear side of the right-angled triangle 7 collides with the two right-angled triangles 7, the right-angled triangle 7 rotates around the rotating column 5, and the rebound column 6 compresses one of the paired return springs 9.

[0027] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
