[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 2The utility model provides an embodiment: a new type of urban road and traffic engineering guardrail, including two pillars 1 for connecting various components, a connecting assembly is commonly provided between the two pillars 1, and a plurality of connecting assemblies are provided for connecting the two pillars 1, the connecting assembly includes a hollow column 3 for cooperating with an extension rod 4, the inner wall of the hollow column 3 is slidably connected with the extension rod 4 for cooperating with the hollow column 3 to adjust the length of the guardrail, the outer wall of the hollow column 3 is penetrated and threadedly connected with a control member 5 for controlling the opening and closing of a plurality of fixed blocks 33, and a fixing assembly 2 is provided at the lower part of the pillar 1 for cooperating with the position limit of the guardrail.

[0033] Furthermore, reflective strips 12 are fixedly connected to the front and rear sides of the outer wall of the pillar 1, which can reflect light when illuminated by a light source in a dim environment, making it easier to find its position and safer. Connecting grooves 13 are provided on the side where the two pillars 1 are close to each other, and there are multiple connecting grooves for cooperating with the connection of the connecting components. A connecting plate 14 is fixedly connected to the bottom surface of the pillar 1 for cooperating with the installation of a universal wheel 15. The bottom of the connecting plate 14 is fixedly connected to the universal wheel 15 for cooperating with the external movement of the guardrail.

[0034] See also Figure 3 The fixing assembly 2 includes a limiting sleeve 21 for limiting the position of the guardrail. The pillar 1 passes through the limiting sleeve 21 and is movably connected thereto. A sleeve 22 is fixedly connected to the top of the limiting sleeve 21 for connecting to the pillar 1 and for adjusting the position of the limiting sleeve 21. The sleeve 22 is threadedly connected to the lower part of the pillar 1.

[0035] like Figure 4 - Figure 5 As shown, a No. 1 stud 31 is fixedly connected to the side of the hollow column 3 close to the pillar 1 for connecting with the pillar 1, and the No. 1 stud 31 is threadedly connected to the connecting groove 13, and a plurality of auxiliary plates 32 are fixedly connected to the side of the hollow column 3 away from the No. 1 stud 31. The auxiliary plates 32 have a certain elasticity and can be deformed to assist the opening and closing of the fixing block 33, and a fixing block 33 is fixedly connected to the side of the auxiliary plate 32 away from the hollow column 3 for fixing the extension rod 4. Multiple fixing blocks 33 can form an oblique ring body, and an anti-slip pad 34 is fixedly connected to the inner wall of the fixing block 33. The anti-slip pad 34 is made of rubber and has anti-slip patterns on the inner wall.

[0036] Furthermore, a No. 2 stud 41 is fixedly connected to the side of the extension rod 4 close to the pillar 1 for connecting with the pillar 1. The No. 2 stud 41 is threadedly connected to the connecting groove 13. A limiting block 42 is fixedly connected to the side of the extension rod 4 away from the No. 2 stud 41 for preventing the extension rod 4 from sliding out of the empty column 3. The limiting block 42 is slidably connected to the inner wall of the empty column 3.

[0037] Furthermore, a control groove 51 which is in the shape of an oblique ring and is adapted to the plurality of fixing blocks 33 is formed on one side of the control member 5 close to the extension rod 4 .

[0038] Working principle: When in use, first tighten the No. 1 stud 31 and No. 2 stud 41 on the empty column 3 and the extension rod 4 to the connecting grooves 13 on the two pillars 1 respectively, so that the connecting assembly can connect the two pillars 1 together. When it is necessary to adjust the length of the guardrail, twist the multiple control members 5 in turn to move them along the empty column 3 toward the direction of the No. 1 stud 31, so that the multiple fixing blocks 33 exit the control groove 51. Without the restriction of the control groove 51, the multiple fixing blocks 33 will open outwards with the assistance of the auxiliary sheet 32 ​​with a certain elasticity, loosen the extension rod 4 fixed by them, and then According to the required length, push the pillars 1 on both sides, and the universal wheels 15 connected to the lower part through the connecting plate 14 will assist in the movement of its position. The extension rod 4 will slide in the empty column 3 under the push of the pillar 1. When the position adjustment is completed, the multiple control members 5 are rotated in the opposite direction in turn to move them in the direction of the extension rod 4. The control groove 51 will slowly be sleeved on the outside of the multiple fixed blocks 33. Since its shape is adapted to the multiple fixed blocks 33, it will control the multiple fixed blocks 33 to move closer to each other and tighten until the anti-slip pad 34 on the inner wall of the fixed block 33 completely clamps the extension rod 4.

[0039] When the guardrail needs to be limited and fixed on the outside, rotate the sleeve 22, which will move downward along the pillar 1 and drive the limiting sleeve 21 to move downward. When the limiting sleeve 21 completely contacts the ground, the guardrail can be fixed on the outside. When the guardrail needs to be moved, just rotate the sleeve 22 in the opposite direction to drive the limiting sleeve 21 to move upward.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
