[0024] The adjustment assembly 4 includes a fixed block 41, a rotating shaft 42, a ratchet 43, a fixed rod 44, a movable plate 45, a telescopic rod 46, a spring 47 and a pull rod 48. The top of the support frame 1 is installed with a fixed block 41, a rotating shaft 42 is provided in the fixed block 41, a ratchet 43 is provided on the outside of the rotating shaft 42, a fixed rod 44 is provided in the fixed block 41, a movable plate 45 is provided on the outside of the fixed rod 44, a telescopic rod 46 is provided on the outside of the movable plate 45, a spring 47 is provided on the inside of the telescopic rod 46, and a pull rod 48 is connected to the inside of the telescopic rod 46;

[0025] By setting the adjustment component 4, the device solves the problem that the existing safety guardrail has a relatively fixed size and can only be moved and adjusted as a whole, resulting in a limited range of protection and limitations.

[0026] Furthermore, the support assembly 5 includes a support column 51 and a water injection port 52. The bottom of the support frame 1 is threadedly connected to the support column 51, and the upper end of the support column 51 is provided with a water injection port 52. Figure 2 As shown, the structure is used to inject water into the support column 51 through the water injection port 52, thereby increasing the overall weight of the device, enhancing the stability of the device, and avoiding tipping.

[0027] Furthermore, the lower end of the rotating shaft 42 is fixedly connected to the movable sleeve 2, the top of the rotating shaft 42 is fixedly connected to the ratchet 43, the fixed rod 44 is fixedly installed in the fixed block 41, the movable plate 45 is rotatably connected to the fixed rod 44, the surface of the movable plate 45 facing the ratchet 43 is fixedly connected to the teeth, and the teeth and the ratchet 43 are meshed with each other, the two ends of the telescopic rod 46 are respectively connected to the movable plate 45 and the inner wall of the fixed block 41, the two ends of the spring 47 are respectively against the telescopic rod 46 and the inner wall of the fixed block 41, the pull rod 48 is connected to the center position of the bottom of the telescopic rod 46, and the other end passes through the surface of the fixed block 41. Figure 4 As shown, this structure is used to rotate the indicator plate 3, drive the ratchet 43 to rotate outward through the rotating shaft 42, and the teeth of the ratchet 43 and the movable plate 45 engage with each other, so that when the ratchet 43 rotates, it pushes the movable plate 45 to rotate outward, causing the telescopic rod 46 to contract and the spring 47 to deform. After the indicator plate 3 is rotated to a suitable angle, the telescopic rod 46 is pushed under the rebound action of the spring 47 to insert the teeth of the movable plate 45 into the gap of the ratchet 43, thereby locking the ratchet 43.

[0028] Furthermore, LED lights 6 are fixedly installed in the two groups of indicator plates 3 at equal intervals, and the LED lights 6 are circular. Figure 2 As shown, the structure is used to display different indication patterns through LED lights 6 to remind or guide directions, making it easier to guide the flow of people.

[0029] Furthermore, a scale line 9 is provided on the top of the fixed block 41, and a pointer 10 is fixedly connected to the top of the rotating shaft 42. Figure 3 As shown, the structure is used to drive the pointer 10 to rotate when the shaft 42 rotates, and the outer scale line 9 indicates the rotation angle. When multiple sets of devices are used, they can be symmetrically distributed in parallel.

[0030] Furthermore, the surfaces of the two groups of indicator plates 3 are provided with vents 7 at equal intervals, and the vents 7 are located between the LED lights 6. Figure 2 As shown, this structure is used to allow air to flow through the vents 7 when the device is placed outdoors in windy conditions, thereby reducing resistance and facilitating heat dissipation inside the indicator panel 3 through the vents 7 between the LED lights 6.

[0031] Furthermore, a slot 8 is provided on the side of the indicator plate 3, and a rubber pad is provided on the surface of the slot 8, and a wavy anti-skid pattern with a depth of two millimeters is provided on the surface of the rubber pad. Figure 2 As shown, the structure is used to pass through the card slot 8. The rubber has cushioning and anti-slip properties. Its anti-slip grooves can enhance its anti-slip effect. Moreover, the depth of two millimeters can be used to ensure that after a certain degree of wear, the anti-slip grooves still have an anti-slip effect, making it easier for the user to rotate the indicator plate 3.

[0032] Working principle: When used, Figure 2 and Figure 4 As shown, when guiding the fork in the road, the user holds the card slot 8 and drives the indicator plate 3 to rotate through the movable sleeve 2. When the indicator plate 3 is rotated, the ratchet 43 is driven to rotate outward through the rotating shaft 42. The teeth of the ratchet 43 and the movable plate 45 are engaged with each other, so that when the ratchet 43 rotates, the movable plate 45 is pushed to rotate outward, causing the telescopic rod 46 to contract and the spring 47 to deform. After the indicator plate 3 is rotated to a suitable angle, the telescopic rod 46 is pushed under the rebound action of the spring 47 to insert the teeth of the movable plate 45 into the gap of the ratchet 43, thereby locking the ratchet 43. Figure 3 As shown, the shaft 42 drives the pointer 10 to rotate when rotating, and the outer scale line 9 indicates the rotation angle, as shown in FIG. Figure 2 As shown, when the device is placed outdoors, water is first injected into the support column 51 through the water inlet 52 to increase the overall weight of the device and enhance the stability of the device. Different patterns can be displayed through the LED lights 6 in the indicator board 3 to facilitate guiding the flow of people. It is also suitable for use at night. The above is the entire working principle of the utility model.

[0033] It will be apparent 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 characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
