DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A road adjustable guardrail structure includes a column 1, and the column 1 is provided with two groups, wherein a first guard plate 2 is provided on the side of one group of columns 1, and a second guard plate 3 is provided on the side of the other group of columns 1. A cavity 5 is opened inside the first guard plate 2, and a bevel gear set 6 is installed at the center position of the cavity 5 through a bearing. The bevel gear set 6 is composed of two groups of bevel gears, and the outer walls of the two groups of bevel gears are connected to the inner wall of the cavity 5 through the bearing, and the two groups of bevel gears are fixedly sleeved on the outer sides of a threaded rod 8 and a first rotating shaft 7, respectively, so that when the staff rotates the first rotating shaft 7, the threaded rod 8 can be driven to rotate, and a first rotating shaft 7 is inserted on the side of the bevel gear set 6, and the other end of the first rotating shaft 7 extends to the external connection of the first guard plate 2. There is a rotating block 12, and a rotating groove matched with the first rotating shaft 7 is opened inside the first guard plate 2, and the inner wall of the rotating groove is connected to the first rotating shaft 7 through a bearing, so as to ensure the stability of the first rotating shaft 7 during rotation. Through the connection of the rotating block 12, it is convenient for the staff to rotate the first rotating shaft 7. A threaded rod 8 is vertically inserted into the interior of the bevel gear set 6, and threaded sleeves 9 are symmetrically sleeved at the upper and lower ends of the threaded rod 8. The ends of the threaded sleeves 9 extend to the outside of the first guard plate 2 and are connected with a clamping plate 11. Two groups of external threads with opposite rotation directions are symmetrically opened at the upper and lower ends of the threaded rod 8, and a threaded groove matched with the external thread is opened inside the threaded sleeve 9. Therefore, when the threaded rod 8 rotates, the two groups of threaded sleeves 9 can be driven to move in opposite directions.

[0024] Further, see Figure 1 and Figure 2 It can be known that a frosted plate 14 is respectively provided on the side away from each other of the first guard plate 2 and the second guard plate 3, and screw holes are opened at the corners of the frosted plate 14. The setting of the screw holes can facilitate the staff to use bolts to connect the frosted plate 14 and the first guard plate 2 and the second guard plate 3. The outer surface of the frosted plate 14 is set to be frosted, so when in use, the staff can attach the reflective sticker to the frosted plate 14. The frosted plate 14 set by the frosted material can ensure the firmness of the reflective sticker during the attachment process.

[0025] Further, see Figure 1 and Figure 5It can be known that the ends of the first guard plate 2 and the second guard plate 3 are respectively connected with the U-shaped plate 4 by bolts, and the side of the U-shaped plate 4 is fixedly connected to the outer wall of the column 1. Through the setting of the U-shaped plate 4, the first guard plate 2 and the second guard plate 3 and the column 1 can be easily disassembled, so that it is convenient for the staff to transport the device.

[0026] Further, see Figure 3 and Figure 5 It can be known that the sides of the clamping plates 11 that are close to each other are respectively connected to the limiting rods 15, and the interior of the second guard plate 3 is laterally equidistantly provided with positioning grooves that are compatible with the limiting rods 15. Through the mutual cooperation between the limiting rods 15 and the positioning grooves, the tightness of the connection between the first guard plate 2 and the second guard plate 3 can be effectively guaranteed.

[0027] Further, see Figure 5 It can be known that the outer wall of the limit rod 15 is evenly covered with a rubber ring 16, and the outer wall of the rubber ring 16 and the inner wall of the positioning groove are tightly fitted. By using multiple groups of rubber rings 16 evenly distributed on the outer wall of the limit rod 15, the tightness of the limit rod 15 inserted in the positioning groove can be further improved, thereby improving the connection effect between the two.

[0028] Further, see Figure 3 It can be known that a slider 10 is connected to the outside of the threaded sleeve 9, and a slideway compatible with the slider 10 is provided inside the first guard plate 2. Through the mutual cooperation of the slider 10 and the slideway, the threaded sleeve 9 can be limited to ensure the stable up and down movement of the threaded sleeve 9.

[0029] Further, see Figure 2 and Figure 3 It can be known that the cross-section of the first guard plate 2 and the second guard plate 3 is set to an L-shaped structure, and the inner sides of the first guard plate 2 and the second guard plate 3 are evenly connected with reinforcing rods 13, and the interiors of the first guard plate 2 and the reinforcing rod 13 are both provided with sliding grooves compatible with the reinforcing rods 13. Through the mutual cooperation of the reinforcing rods 13 and the sliding grooves, the stability of the first guard plate 2 and the second guard plate 3 during the pulling process can be guaranteed, and the structural strength of the device can be effectively improved.

[0030] Working principle: When the utility model is in use, the staff can first manually rotate the rotating block 12 according to the use requirements, so that the first rotating shaft 7 can be rotated at the same time, and the bevel gear set 6 arranged on the inner side of the first rotating shaft 7 can drive the threaded rod 8 to rotate in the reverse direction, so that the two groups of threaded sleeves 9 can be threadedly matched with them, so as to drive the two groups of clamping plates 11 connected to the ends of the threaded sleeves 9 to move away from each other. At this time, the limiting rod 15 connected to the outer side of the clamping plate 11 can be pulled out from the positioning groove provided in the second guard plate 3, and then the staff can pull the first guard plate 2, so that the first guard plate 2 and the second guard plate 3 are connected. The combined length of the two guard plates 3 changes. After the spacing between the two groups of columns 1 is adjusted to a suitable length, the staff can reversely rotate the rotating block 12 again to allow the two groups of limit rods 15 connected to the sides of the slider 10 to engage with the positioning grooves provided inside the second guard plate 3 to achieve the docking operation between the first guard plate 2 and the second guard plate 3. During the sliding of the first guard plate 2, the sliding groove provided inside it is forced to slide along the outer surface of the reinforcing rod 13 to guide the first guard plate 2. At the same time, the structural strength of the device during use can be improved. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
