In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] like Figures 1 to 5As shown, the present embodiment is a safe, stable and wind-resistant construction engineering sign installation structure, including a back plate 1, with centripetal splints 2 provided on both sides of the back plate 1, the two centripetal splints 2 clamp the two sides of the sign, and are suitable for signs of different sizes. Two inner columns 10 are provided at the rear end of the back plate 1, and the outer surfaces of the bottoms of the two inner columns 10 are provided with outer columns 8. The inner columns 10 can adjust the height, so that signs with different warning effects can be raised to the required height. The bottom ends of the two outer columns 8 are commonly connected to a base 6, and the base 6 has a fixing effect. A lower splint 3 is provided at the bottom end of the back plate 1, and a slot 4 is provided at the top of the lower splint 3 near the back plate 1. The lower splint 3 clamps the bottom of the sign through the slot 4, fixes the sign tightly, and prevents it from falling off due to wind.

[0023] Specifically, four cavities 14 are provided inside the back panel 1, and extension columns 11 are provided inside the four cavities 14. A disk 13 is provided at one end of the four extension columns 11, and the disk 13 is adapted to the cavity 14. A positioning spring 12 is provided on the outer surface of the extension column 11 inside the cavity 14. When installing the sign, the two centripetal clamps 2 are pulled toward the two sides of the back panel 1, and the extension columns 11 will be pulled to perform linear movement toward the two sides of the back panel 1. At the same time, the positioning springs 12 are squeezed. After the sign is placed on the front end of the back panel 1, the two centripetal clamps 2 are loosened, and the positioning springs 12 release the elastic force to move the two centripetal clamps 2 toward the two sides of the sign to clamp the sign.

[0024] Furthermore, two extension columns 11 form a group, and one end of each group of two extension columns 11 extends out of both sides of the back panel 1. The extended ends of each group of two extension columns 11 are commonly connected to one side edge of the centripetal splint 2, fixing the centripetal splint 2 at a predetermined position, so that the two centripetal splints 2 can clamp the sign so that it is firmly installed on the front end of the back panel 1, and the installation or disassembly steps are simple.

[0025] Furthermore, a limiting groove 17 is provided inside the lower clamping plate 3, and a reinforcing plate 15 is provided inside the limiting groove 17, and the rear end of the reinforcing plate 15 extends into the slot 4, and a plurality of return springs 16 are provided at the front end of the reinforcing plate 15 inside the limiting groove 17. When installing the sign, the bottom end of the sign is inserted into the slot 4. When the bottom end of the sign contacts the top end of the reinforcing plate 15, since the top end of the reinforcing plate 15 is an inclined surface, the reinforcing plate 15 will be squeezed to shrink into the limiting groove 17, and the return spring 16 will be squeezed at the same time. When the bottom of the sign is completely inserted into the slot 4, the front end surface of the reinforcing plate 15 is pushed by the elastic force of the return spring 16 to fit tightly against the front end of the sign, thereby clamping the bottom of the sign.

[0026] Furthermore, a counterweight drawer 5 is detachably installed inside the base 6. After the installation of the sign is completed, the counterweight drawer 5 is pulled out, and heavy objects such as stones or sandbags are placed inside to increase the weight of the base 6 to prevent collapse due to wind.

[0027] Furthermore, a spring button 9 is provided at the bottom of the front end of the internal column 10, and a plurality of holes 7 are equidistantly arranged on the front end surface of the external column 8. The spring button 9 is movably connected to any one of the holes 7. The external column 8 is connected to the holes 7 at different positions through the spring button 9 for height adjustment, so that the sign can be lifted to different heights.

[0028] The method of using this embodiment is as follows: when installing the sign, the two centripetal clamps 2 are pulled toward the two sides of the back plate 1, and the extension column 11 will be pulled toward the two sides of the back plate 1 for linear movement, while the positioning spring 12 is squeezed. After the sign is placed at the front end of the back plate 1, the two centripetal clamps 2 are released, and the positioning spring 12 releases the elastic force, so that the two centripetal clamps 2 move toward the two sides of the sign to clamp the two sides of the sign. The bottom end of the sign is inserted into the slot 4 and contacts the top of the reinforcement plate 15. Since the top of the reinforcement plate 15 is an inclined surface, the reinforcement plate 15 will be squeezed to shrink toward the inside of the limiting groove 17, and the reset spring 16 will be squeezed. When the bottom of the sign is completely inserted into the slot 4, the front end surface of the reinforcement plate 15 is pushed by the elastic force of the reset spring 16 to be close to the front end of the sign to clamp the bottom of the sign. After the installation is completed, the counterweight drawer 5 is pulled out, and heavy objects such as stones or sandbags are placed inside to increase the weight of the base 6 to prevent it from collapsing due to wind.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
