[0018] The utility model will be described in further detail below in combination with the specific embodiment and the drawing:

[0019] As Figure 1 Indicated, a kind of isolation guardrail anti-collision device, including the multiple stand 1 of guardrail, and the bottom of stand 1 is fixed with road by base 2, and adjacent stand is connected by two cross pipes 3, and buffer baffle 4 is set between adjacent two stands outer side, and the upper end and lower end of buffer baffle 4 are connected with corresponding cross pipe 3, and multiple support spring 9 is attached with its two ends fixed in buffer baffle 4 inner side.

[0020] As Figure 2 Indicated, the upper end and lower end of buffer baffle 4 are respectively provided with the arc sleeve 5 of sleeveing on the outer wall of cross pipe 3, and arc sleeve 5 is used to cross and be wound on the outside of cross pipe 3.

[0021] As Figure 3 Indicated, the end of arc sleeve 5 is bent to form bending area 6 along guide rod 7 and extend downward and be fixed with pull rod 8, and when pull rod 8 is fixed with multiple support spring 9, the uniformity of partial force of buffer baffle 4 can be guaranteed, prevent local force from being too large and damaging phenomenon occurs.

[0022] As Figure 3As shown, a plurality of supporting springs 9 are connected between the upper and lower pull rods 8, the supporting springs 9 can be hung in the holes of the pull rod 8 through hooks, the installation and fixation are convenient, and the interval between the adjacent supporting springs 9 can be set to 10-15cm, so that 3-4 springs can act simultaneously when the buffer baffle 4 is impacted, and the force is more reasonable and uniform. If the interval of the supporting springs 9 is set too large, the number of the supporting springs 9 subjected to force is less when the collision occurs, and the protection effect is not good; and if the interval is set too small, the number of the supporting springs 9 subjected to force is more when the collision occurs, and the protection effect is also not good, and the production cost is higher.

[0023] As shown in the figure, Figure 3 As shown, the guide rod 7 is installed on the inclined side of the horizontal pipe 3 and close to the buffer baffle 4, and the two ends are fixed with the stand column 1, and through the guiding effect of the guide rod 7, the supporting spring 9 fixed at the end of the buffer baffle 4 can be closely attached to the buffer baffle 4, and the attachment supporting effect is good.

[0024] The diameter of the pull rod 8 is less than the interval distance between the side of the guide rod 7 and the corresponding horizontal pipe 3, so that the pull rod 8 can pass through the upper part of the guide rod 7 when installed, and the installation is convenient and efficient.

[0025] The buffer baffle 4, the arc-shaped sleeve 5 and the bending area 6 are integrally arranged, and the buffer baffle 4, the arc-shaped sleeve 5 and the bending area 6 are arranged by using the flexible plastic plate with a thickness of 2-3mm, which has good deformation ability and good buffering effect.

[0026] The implementation principle of the isolation guardrail anti-collision device in the embodiment of the utility model is:

[0027] The side of the isolation guardrail provided with the buffer baffle 4 faces the non-motor vehicle lane, when the electric bicycle of the non-motor vehicle lane collides with the isolation guardrail, the driver will collide with the buffer baffle 4, the buffer baffle 4 deforms inward after being subjected to force, the upper and lower arc-shaped sleeves 5 and the bending areas 6 of the buffer baffle 4 move along the guide rod 7, so that the supporting spring 9 is elongated to play a buffering effect, and as the buffer baffle 4 continues to deform inward, the plurality of supporting springs 9 close to the buffer baffle 4 are also deformed and elongated due to the external force, and play an intercepting and buffering effect, so as to avoid the rigid collision between the driver and the guardrail, and the personal safety of the driver can be well protected.

[0028] When the driver separates from the buffer baffle 4 of the isolation guardrail after the collision, the buffer baffle 4 is not subjected to force, and under the rebounding force of the plurality of supporting springs 9 at the back, the buffer baffle 4 will continue to be straightened and be in the initial tight state, and the supporting spring 9 will also return to the initial position. Therefore, the recovery of the isolation guardrail anti-collision device after the collision is strong, and the device can timely buffer the next collision.

[0029] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
