[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0033] Example 1

[0034] Reference Figure 1 , 2 10, 3, 4, 5, 10 are the first embodiment of this utility model, which provides a moving mechanism 100 that enables the convenient extension and retraction of traffic guardrails and their installation.

[0035] Specifically, the caster wheel 101 includes a first bearing 101a, a second bearing 101b, a roller 101c, a connecting rod 101d, a toothed column 101e, and a connecting plate 101f. The first bearing 101a is located inside the connecting plate 101f. The roller 101c is located at the bottom of the connecting plate 101f. The toothed column 101e is located inside the roller 101c. The second bearing 101b is located inside the toothed column 101e. The connecting rod 101d is fixedly connected to the middle of the connecting plate 101f. The connecting rod 101d is used to connect the connecting plate 101f and the roller 101c. When people move the traffic barrier, the locking mechanism 200 is closed first to remove the fixation of the caster wheel 101 before the traffic barrier can be moved.

[0036] Furthermore, when the staff needs to move the traffic barrier, they first push the spring plate 202c. When the spring plate 202c retracts, it no longer covers the perforated plate 201b, causing the first spring 201d below the perforated plate 201b to rebound, thereby driving the perforated plate 201b to rise. When the perforated plate 201b rebounds and rises, it drives the locking tooth 201e to rise, thus no longer limiting the tooth post 101e and achieving the movement effect.

[0037] It should be noted that the moving mechanism 100 and the locking mechanism 200 are mutually constrained. When the moving mechanism 100 is not locked, the traffic barrier can be moved, in which case the locking mechanism 200 needs to be closed.

[0038] Example 2

[0039] Reference Figure 2 , 3 4, 5, and 6 are the second embodiment of this utility model. This embodiment provides a locking mechanism 200, which can prevent the traffic guardrail from moving when the height of the guardrail is raised or lowered, which may cause the traffic guardrail to deviate and thus cause a traffic accident. This solution can fix the moving mechanism 100, making it safer and more convenient for workers to install traffic guardrails.

[0040] Specifically, the base 201 includes a first hole 201a on the outside of the base 201, a perforated plate 201b inside the base 201, a connecting piece 201c at the bottom of the perforated plate 201b, a second hole 201b-1 on the perforated plate 201b, a first spring 201d at the bottom of the connecting piece 201c, a locking tooth 201e at the bottom of the connecting piece 201c, a first telescopic buckle 202a on the outside of the column 202, a support plate 202b at the bottom of the column 202, and a spring plate 202c on the right side of the column. When people need to adjust the height of the traffic barrier, they can first press the perforated plate 201b and then manually adjust the height of the traffic barrier.

[0041] Furthermore, when raising the traffic barrier, people need to first press the perforated plate 201b to lower it. When the perforated plate 201b is not lowered, the spring plate 202c, installed on one side of the perforated plate 201b, rests against the top of the perforated plate 201b. When the perforated plate 201b lowers to a certain height beyond the spring plate 202c, the spring plate 202c extends to cover the perforated plate 201b, thus restricting its movement. After the worker presses the perforated plate 201b down and it is covered by the spring plate 202c, the second hole 201b-1 on the perforated plate 201b coincides with the first hole 201a on one side of the base 201. Then, the column 202 is manually raised to the desired height. During the ascent, the device will be secured within the first hole 201a and the second hole 201b-1. When the worker needs to raise or lower the device again, they only need to press the first buckle 201a-1 on the first telescopic buckle 202a. The first buckle 201a-1 will retract into the first buckle shell 202a-3, thus disengaging from the first hole 201a. When the worker exits the first hole 201a and raises the device, because the top surface of the first buckle 201a-1 of the first telescopic buckle 202a on one side of the column 202 is arc-shaped, it will be subjected to the squeezing force of the second hole 201b-1, causing the first buckle 201a-1 to descend and exit from the second hole 201b-1, thus allowing the height to be adjusted again.

[0042] It should be noted that the second hole 201b-1 on the perforated plate 201b is located above the first hole 201a on one side of the base 201. When the perforated plate 201b is pressed down, the first telescopic buckle 202a on the side of the column 202 will be fully penetrated when the second hole 201b-1 on the perforated plate 201b coincides with the first hole 201a on one side of the base 201, thus achieving the function of fixing.

[0043] Example 3

[0044] Reference Figure 1 , 7 8 is the third embodiment of this utility model. This embodiment provides a telescopic mechanism 300, which reduces the volume of the traffic guardrail during transportation, thereby facilitating loading, unloading or transportation, and also making it convenient and quick for workers to install the guardrail.

[0045] Specifically, the telescopic mechanism 300 includes a telescopic rod 301, which includes a housing 301a, an extension rod 301b inside the housing 301a, a slide rail 301c at the bottom of the extension rod 301b, a third hole 301d on one side of the housing 301a, a retaining plate 301e inside the housing 301a, an air pump 301b-1 inside the extension rod 301b, a second telescopic buckle 301b-2 at the top of the air pump 301b-1, and a sliding groove 301b-3 inside the extension rod 301b. When people need to extend the length of the guardrail, they only need to pull the telescopic rod 301 to adjust the length of the guardrail.

[0046] Furthermore, when using the telescopic pole 301 to extend or retract the traffic barrier, the worker first places the traffic barrier in a suitable position, raises the post 102 to the required height, and then extends or retracts the telescopic pole 301. When adjusting the length of the telescopic pole 301, the slide groove 301b-3 inside the extension pole 301b moves according to the slide rail 301a-1 inside the outer shell 301a. When the extension pole 301b slides, the second buckle 301b-a in the second telescopic buckle 301b-2 at the top will pass through the third hole 301d at the top of the outer shell 301a, because the top surface of the second buckle 301b-2a is set with The extension rod 301b is arc-shaped. When people quickly pull the extension rod 301b, the second buckle 301b-2a is lowered due to the squeezing force of the third hole 301d. When the desired length is reached, the air pump 301b-1 at the bottom of the second telescopic buckle 301b-2 can be activated to raise the height of the second telescopic buckle 301b-2, so that the second buckle shell 301b-2b completely passes through the third hole 301d, achieving a fixing effect. When people need to adjust the length of the traffic barrier, they only need to turn off the air pump 301b-1 to lower the second telescopic buckle 301b-2, and the length of the telescopic rod 301 can be adjusted again.
