[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a road construction sign. Figure 1-3A road construction sign comprises a support base 1, a fixed inner cavity 2 is provided inside the support base 1, a side of the inner wall of the fixed inner cavity 2 extends to the outside of the support base 1 and is movably installed with a plurality of movable support plates 3, a fixed seat 5 is welded to the edge of the upper surface of the movable support plate 3, a hollow tube 6 is rotatably installed inside the fixed seat 5, a spring 7 is installed inside the hollow tube 6, a movable connecting rod 8 is movably installed on one side of the spring 7 extending to the outside of the hollow tube 6, the outer diameter of the movable connecting rod 8 is smaller than the inner diameter of the top opening of the hollow tube 6, and the hollow tube 6 and the movable connecting rod 8 are They are coupled to each other, and a connecting plate 9 is hinged on one side edge of the multiple movable connecting rods 8. A supporting sleeve 10 is integrally formed in the middle of the top end of the connecting sleeve 9. A supporting column 11 is inserted into the support sleeve 10. The outer diameter of the support column 11 is smaller than the inner diameter of the top opening of the support sleeve 10. The bottom of one side of the support column 11 is located inside the support sleeve 10. The support sleeve 10 and the support column 11 are interlocked with each other. An identification plate 12 is fixedly installed on the top of the support column 11. A rotating mechanism is also provided inside the support base 1 for adjusting the multiple movable support plates 3 for movement.

[0020] By placing the support base 1 in the construction area, the movable support plate 3 drives the movable connecting rod 8 to move along the inside of the hollow tube 6, so that the hollow tube 6 cooperates with the movable connecting rod 8 to expand and lift the connecting plate 9 as a whole, and at the same time, the spring 7 abuts against the outer surface of the movable connecting rod 8 to keep the connecting plate 9 in a stable state, and the support column 11 is inserted into the inside of the support sleeve 10 to keep the identification plate 12 in a stable placement state. When the identification plate 12 is accidentally touched and drives the connecting plate 9 to shake, the movable connecting plate 9 drives the movable connecting rod 8 to embed into the hollow tube 6 to a certain depth and compress the spring 7, so that the spring 7 buffers and supports the movable connecting rod 8, and then the movable connecting rod 8 is stabilized in the hollow tube 6 again, which reflects the buffering and resetting effect when the identification plate 12 shakes.

[0021] Reference Figure 2 and Figure 3 The rotating mechanism includes a movable disc 13, which is rotatably mounted at the middle of the bottom end of the inner wall of the fixed inner cavity 2. A plurality of movable connecting plates 14 are rotatably mounted on the edge of the upper surface of the movable disc 13. The top edge of the movable connecting plate 14 is hinged to the other side edge of the bottom end of the movable support plate 3. The middle of the top of the movable disc 13 extends to the upper surface of the support base 1 where a knob 15 is mounted.

[0022] By turning the knob 15, the movable disc 13 and the multiple movable connecting plates 14 are driven to rotate synchronously, so that the rotating movable connecting plate 14 drives the movable support plate 3 to slide out along the inside of the fixed inner cavity 2, so that the multiple movable support plates 3 increase the overall support range of the support base 1, and help to adjust the inclination angle of the hollow tube 6, so that the movable connecting rod 8 has a better supporting effect, reflecting the overall supporting effect of the movable support plate 3.

[0023] Reference Figure 1 and Figure 3 A support block 4 is fixedly connected to the bottom edge of the movable support plate 3, and the lower bottom surface of the support block 4 is on the same horizontal plane as the bottom end of the support base 1. By making the support block 4 support the movable support plate 3 after movable adjustment, the support block 4 is stably placed on the ground, which reflects the overall stability of the movable support plate 3 when placed.

[0024] The implementation principle of a road construction sign in the embodiment of the present application is as follows: by placing the support base 1 at the construction area, turning the knob 15 drives the movable disc 13 and multiple movable connecting plates 14 to rotate synchronously, so that the rotating movable connecting plate 14 drives the movable support plate 3 to slide out along the fixed inner cavity 2, so that the support block 4 supports the movable support plate 3 after the movable adjustment, and at the same time, the movable movable support plate 3 drives the movable connecting rod 8 to move along the inside of the hollow tube 6, so that the hollow tube 6 cooperates with the movable connecting rod 8 to expand and lift the connecting disc 9 as a whole, and at the same time, the spring 7 abuts against the outer surface of the movable connecting rod 8 to keep the connecting disc 9 in a stable state, and the support column 11 is inserted into the support sleeve Inside the tube 10, the identification plate 12 is kept in a stable placement state. When the identification plate 12 is accidentally touched and the connecting plate 9 shakes, the movable connecting plate 9 drives the movable connecting rod 8 to embed into the hollow tube 6 to a certain depth, and compresses the spring 7, so that the spring 7 buffers and supports the movable movable connecting rod 8, and then the movable connecting rod 8 is stabilized in the hollow tube 6 again, so that the spring 7 cooperates with the movable connecting rod 8 to support the connecting plate 9 as a whole; compared with the prior art, this scheme has the effect of facilitating the buffering and supporting of the identification plate 12 when it is accidentally touched, improves the overall stability of the identification plate 12 when it is placed, and solves the problem of the identification plate 12 tipping over and affecting the use efficiency.
