Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Referring to Figures 1-4 , a convenient guardrail for road surface planning and maintenance includes two symmetrically arranged support frames 1. A plurality of moving seats 4 are slidably connected to each support frame 1. A limit sliding groove 2 is opened on the outer side wall of each support frame 1. A first threaded column 10 is fixedly connected to the side wall of each moving seat 4. Each first threaded column 10 passes through the corresponding limit sliding groove 2 and is threadedly connected with a first locking nut 5. An installation cavity 16 is opened in each moving seat 4 on one of the support frames 1. An installation roller is rotatably installed in each installation cavity 16. A retaining strip 3 is installed on the installation roller. A light-emitting coating is intermittently coated on the retaining strip 3 to improve the visibility. One end of the retaining strip 3 away from the installation roller passes through the moving seat 4 and is fixedly connected with a clamping seat 11. A clockwork spring is jointly installed between the installation roller and the inner wall of the installation cavity 16. After the device is used, the clamping strip can drive the retaining strip 3 to wind around the installation roller, driving the clamping seat 11 to return to its original position, avoiding manual winding of the retaining strip 3 and saving time;

[0024] A clamping groove and a through hole are opened on each moving seat 4 on the other support frame 1, and the clamping groove and the through hole are communicated. A clamping hole is opened on each clamping seat 11. When the clamping seat 11 drives the retaining strip 3 to be clamped in the clamping groove, the clamping seat 11 is fixed by passing a clamping column through the through hole and clamping it inside the clamping hole. The clamping column can be fixed on the moving seat 4 through a spring, or can be threadedly connected with the through hole and fixed on the moving seat 4;

[0025] Two moving frames 9 are symmetrically and slidably connected to each support frame 1. Two through slots 8 are symmetrically formed in the side walls of each support frame 1. A second threaded column 13 is fixedly connected to the side wall of each moving frame 9. Each second threaded column 13 passes through the corresponding through slot 8 and is threadedly connected with a second locking nut 14. A plurality of moving slots 15 are symmetrically formed in each support frame 1. Each moving frame 9 is clamped in two corresponding moving slots 15. Two support rods 6 are symmetrically and rotatably connected to both ends of each moving frame 9. A support plate 7 is jointly installed on two corresponding support rods 6. A rubber anti-slip pad is fixedly connected to the lower end surface of each support plate 7. Anti-slip lines are formed on the lower end surface of the rubber anti-slip pad to increase the friction between the support plate 7 and the ground and enhance the stability of the device. A spherical card slot is formed in each support plate 7. A rotating ball 12 is fixedly connected to the lower end of each support rod 6. Each rotating ball 12 is clamped in the corresponding spherical card slot. The depth of the spherical card slot is greater than the radius of the rotating ball 12 to ensure that the rotating ball 12 can be clamped in the spherical card slot without detachment. The arrangement of the rotating ball 12 and the spherical card slot can ensure that the support plate 7 can rotate at various angles within a certain range, ensuring that the lower surface of the support plate 7 can be completely attached to the ground.

[0026] When the utility model is in use, first loosen the second locking nut 14 so that the moving frame 9 can move in the vertical direction of the moving slot 15. After moving the moving frame 9 to a suitable position, tighten the second locking nut 14 to fix the moving frame 9 on the support frame 1, so that the support plate 7 is in full contact with the ground to support the support frame 1. After placing a plurality of support frames 1 at the positions to be intercepted, then adjust the heights of the respective moving seats 4 through the first threaded column 10 and the first locking nut 5 and lock them. Drag the clamping seat 11, and the clamping seat 11 drives the corresponding blocking strip 3 to be released from the mounting roller until the blocking strip 3 is clamped in the card slot on the corresponding moving seat 4. Insert a clamping column into the card hole on the clamping seat 11 through the through hole to fix the clamping seat 11 in the card slot on the corresponding moving seat 4.

[0027] It should be noted that when interception is not required, the moving frame 9 can be moved to the highest position of the moving slot 15 through the second threaded column 13 and the second locking nut 14. Rotate the support rod 6 to be parallel to the support frame 1, and rotate the lower surface of the support plate 7 to correspond to the outer side wall of the support frame 1. Stack the respective moving seats 4 on the same support frame 1 through the first threaded column 10 and the second locking nut 5, which is convenient for the transportation and stacking of the support frame 1.

[0028] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
