[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a mountain highway safety warning sign, referring to Figure 1-Figure 4, including a bottom plate 1, a support column 2 is fixedly installed on the top of the bottom plate 1, a movable seat 4 is arranged inside the support column 2, a rack plate 5 is fixedly installed on the right side of the bottom of the movable seat 4, a rotating hand wheel 6 is installed on the front surface of the support column 2, a connecting rod 7 is fixedly installed on the inner end of the rotating hand wheel 6, an inner end of the connecting rod 7 passes through the support column 2 and is installed with a ratchet 9, a brake gear 8 is fixedly installed on the connecting rod 7 on the inner middle side of the support column 2, the outer surface of the brake gear 8 is meshed with the outer surface of the rack plate 5, and the rotating hand wheel 6 is used to rotate to drive the brake gear 8 located inside the support column 2 to rotate, and when the brake Under the meshing action of the gear 8 and the rack plate 5 at the bottom of the movable seat 4, the movable seat 4 is driven to move up and down inside the support column 2, so that the staff can adjust the height of the warning sign body 14 at will after it is installed, so that the safety warning sign can adapt to the height differences of different road sections, ensuring that it is always within the driver's line of sight, enhancing the applicability of the device, and a limiting groove 3 is opened on the left side inside the support column 2, and the left side of the bottom of the movable seat 4 is movably connected to the inside of the limiting groove 3. Through the mutual cooperation between the limiting groove 3 and the bottom of the movable seat 4, when the movable seat 4 is adjusted up and down, the stabilizing effect is better.

[0021] Reference Figure 1-Figure 4 A fixing seat 10 is fixedly installed in the middle of the rear surface of the support column 2. The fixing seat 10 is internally movably connected with a limit stop rod 11. The bottom of the limit stop rod 11 is clamped on the side of the ratchet 9. The limit stop rod 11 is located on the inner and outer surfaces of the fixing seat 10, and a stop piece is arranged. A return spring 12 is arranged on the outside of the limit stop rod 11. One end of the return spring 12 is fixedly installed on the surface of the stop piece, and the other end of the return spring 12 is fixedly installed on the upper end of the inner surface of the fixing seat 10. With the help of the thrust of the return spring 12, the limit stop rod 11 always maintains a downward force to limit the reverse rotation of the ratchet 9. When the rotating hand wheel 6 needs to be rotated in the reverse direction, the limit stop rod 11 needs to be pulled up To ensure the stability of the warning sign body 14 after adjusting the height, two support plates 13 are fixedly installed on the top of the movable seat 4, and the warning sign body 14 is fixedly installed on the top of the two support plates 13. A warning light 15 is fixedly installed on the top of the warning sign body 14. By installing the warning light 15 on the upper end of the warning sign body 14, it is convenient to continuously emit flashing lights in an environment with low visibility, thereby improving the warning effect of the device. Sound players 16 are symmetrically fixedly installed on the two side surfaces of the warning sign body 14. In conjunction with the two sound players 16, warning prompt sounds are played, which further enhances the driver's driving alertness and ensures the safety of the road section.

[0022] The implementation principle of a mountain highway safety warning sign in an embodiment of the present application is as follows: when using the device, first use bolts and other mounting components to install the device to a specified position on a mountain highway, and then according to the height difference of the road section, turn the rotating handwheel 6 to drive the brake gear 8 located inside the support column 2 to rotate, and under the meshing action of the brake gear 8 and the rack plate 5 at the bottom of the movable seat 4, drive the movable seat 4 to move up and down inside the support column 2, thereby adjusting the warning sign body 14 to the required height, and while rotating the brake gear 8, drive the ratchet 9 to rotate synchronously on the back of the support column 2, and when the rotation stops, the limit lever 11 will be moved to the side of the ratchet 9 under the action of the reset spring 12 to fix the ratchet 9, thereby limiting the reverse rotation of the rotating handwheel 6 and ensuring the stability of the warning sign body 14 after the height is adjusted.
