[0028] Specifically, considering the risk of non-motor vehicles such as pedestrians and bicycles directly colliding with the roller 117 and causing a tripping accident, a retractable protective plate 115 is provided on one side of the mounting frame 11, and a roller 117 for cushioning the impact of vehicles is provided between the two mounting frames 11. A fixed shaft 119 is provided at the center of the roller 117. In order to enhance the stability of the roller 117, a plurality of legs 119 fixed to the bottom of the mounting frame 11 are provided at both ends of the fixed shaft 119.

[0029] The improvement of this embodiment lies in that: by arranging a plurality of branch legs 119 at both ends of the fixed shaft and fixing them on the mounting frame 11, the fixing effect of the fixed shaft is strengthened to prevent the vehicle from directly knocking the rotating shaft out of the guardrail in the event of a high-speed collision, causing the roller 117 to detach from the guardrail and cause further accident damage; by arranging a protective plate 115 on one side of the mounting frame 11, the protective plate 115 is used to prevent pedestrians or non-motor vehicles such as bicycles from directly colliding with the roller 117, thereby avoiding tripping accidents.

[0030] Considering the installation and fixation of the mounting frame 11 and the specific introduction of the installation of the fixed shaft 119, the second embodiment of the present utility model is shown.

[0031] Further, a plurality of clamping blocks 111 are symmetrically arranged on both sides of the mounting frame 11; a clamping slot 121 is symmetrically arranged on both sides of the fixing frame 12; a first screw hole 123 and a second screw hole 124 are provided on the clamping blocks 111 and the clamping slot 121 to match each other; a bolt passes through the first screw hole 122 and the second screw hole 123 to fix the mounting frame 11 and the fixing frame 12.

[0032] In this embodiment, a plurality of clamping blocks 111 are symmetrically provided on both sides of the mounting frame 11, and a clamping slot 121 is symmetrically provided on both sides of the fixing frame 12. Both the clamping blocks 111 and the clamping slot 121 are provided with a first screw hole 122 and a second screw hole 123. After the clamping blocks 111 and the clamping slots 121 are clamped together, the mounting frame 11 is fixed to the fixing frame 12 by bolts, so that the mounting frame 11 and the fixing frame 12 become a whole.

[0033] Specifically, the mounting frame 11 is provided with a socket 112 on one side adjacent to the setting block 111 ; the protective plate 115 is provided with a plug post 116 on one side near the socket 112 ; a spring 114 is provided on the outer sleeve of the plug post 116 ; and the plug post 116 is slidably connected in the socket 112 .

[0034] In this embodiment, a socket 112 is provided on one side of the mounting frame 11, and a column 116 is provided on one side of the protective plate 115. A spring 114 is fixed between the column 116 and the socket 112. The protective plate 115 is fixed to the mounting frame 11 by plugging the column 116 into the socket 112. By utilizing the elastic force of the spring 114, the protective plate 115 can block pedestrians and will not affect the use of the roller 117 during a high-speed collision.

[0035] Specifically, the fixed shaft corresponds to the roller 117 one by one; the fixed shaft is arranged at the axis of the roller 117; the legs 119 spread outward from the fixed shaft to the outside of the top or bottom of the roller 117; each fixed shaft forms at least four legs 119 on the upper and lower sides of the roller 117. The bottom or top of the mounting frame 11 is provided with through holes 113 corresponding to the legs 119 one by one; the ends of the legs 119 are inserted into the through holes 113.

[0037] In this embodiment, a plurality of through holes 113 are provided at the bottom or top of the mounting frame 11, and the legs 119 at both ends of the fixed shaft are respectively inserted into the through holes 113 and fixed with bolts, so that the fixed shaft 119 is fixed on the mounting frame 11, and protective plates 118 are symmetrically provided at the upper and lower ends of the roller 117. The protective plates 118 are circular and fixed to the fixed shaft 119, so that the roller 117 will not be stuck by the legs of the bottom fixed shaft 119 when rotating.

[0038] In summary, the working principle of this solution is as follows:

[0039] Take out a mounting frame 11, engage the block 111 of the mounting frame 11 with the slot 121 at the lower end of the fixing frame 12, and fix it with bolts through the first screw hole 122 and the second screw hole 123 of the block 111 and the slot 121, and insert the legs 119 of the fixed shaft into the through holes 113 of the mounting frame 11 in sequence. Then take out the second mounting frame 11, align the through holes 113 of the mounting frame 11 with the legs 119 at the other end of the fixed shaft and insert and fix them. At the same time, the blocks 111 at both ends of the mounting frame 11 are engaged with the slot 121 at the upper end of the fixing frame 12 and then fixed with bolts. Use bolts to fix the legs 119 of the fixed shaft to the mounting frame 11, and adjust the position of the protective plate 115 so that the side distance of the protective plate 115 is slightly larger than the side distance of the roller 117.
