[0015] Beneficial effects:
[0016] The present utility model provides a highway isolation fence structure. When the whole stabilizing cylinder is replaced, the operator continuously rotates the stabilizing cylinder, so that the threaded rod continuously moves upward, thereby driving the sliding block located below to jack up the two limiting blocks, and making the bottom of the sliding block fit with the limiting blocks. Then, the operator reversely rotates the stabilizing cylinder, so that the threaded rod moves downward. Since the limiting blocks tightly press the bottom of the sliding block, the sliding block will be driven to slide on the sliding rod, and the upper surface of the sliding block will fit with the lower surface of the fixed block, making the sliding block and the fixed block close to each other.

The locking holes 6 are respectively opened on the top of the support column 1 and the fixing rod 7 on the top column 12. The fixing bolts 3 are arranged inside the locking holes 6. The top column 12 and the support column 1 are fixedly connected by the fixing bolts 3, improving the stability of the top column 12 during installation and avoiding the situation that the top column 12 falls off from the support column 1.
[0025] Further, a plurality of locking mechanisms are provided on the top column 12; the locking mechanism includes a mounting base 18, the mounting base 18 is fixedly installed below the top column 12, placing holes 17 are formed in the top column 12 and the mounting base 18, guide holes 25 are formed on both sides of the placing hole 17 inside the mounting base 18, a placing cavity 20 is formed on one side of the guide hole 25 on the mounting base 18, a storage cavity 23 is formed on one side of the placing cavity 20 on the mounting base 18, a limiting block 21 is arranged inside the storage cavity 23, one side of the limiting block 21 is inclined, a guide rod 19 is fixedly installed on one side of the limiting block 21, the guide rod 19 is inserted inside the guide hole 25, a return spring 24 is arranged on the outer side of the guide rod 19, the return spring 24 is arranged inside the placing cavity 20, and both ends of the return spring 24 are respectively fixedly installed on the limiting block 21 and the inner side of the mounting base 18, a fixing block 22 is inserted inside the placing hole 17, the bottom of the fixing block 22 tightly abuts against the upper surface of the limiting block 21, a sliding rod 27 is fixedly installed at the bottom of the fixing block 22, a sliding block 26 is slidably arranged on the outer side of the sliding rod 27, both the sliding block 26 and the fixing block 22 are conical, the sliding block 26 and the fixing block 22 are arranged oppositely, the outer circles of the sliding block 26 and the fixing block 22 are fitted with the inner wall of the placing hole 17, the outer circle of the sliding block 26 tightly abuts against the bottom of one side of the limiting block 21, which plays a role in limiting the sliding block 26 and reduces the jamming situation between the limiting block 21 and the sliding block 26, a threaded rod 16 is fixedly installed at the bottom of the sliding rod 27, a stabilizing cylinder 14 is arranged on the outer side of the threaded rod 16, a connection hole 9 is formed on the bottom column 10, a stabilizing column 15 is fixedly installed at the bottom of the stabilizing cylinder 14, and the stabilizing cylinder 14 is rotatably arranged inside the connection hole 9 through the stabilizing column 15 for installing the stabilizing cylinder 14 and enabling the stabilizing cylinder 14 to rotate on the bottom column 10. Specifically, the stabilizing cylinder 14 is placed between the top column 12 and the bottom column 10, and then the whole stabilizing cylinder 14 is inserted onto the bottom column 10 through the stabilizing column 15.After completion, the operator stabilizes the threaded rod 16, and then turns the stabilizing cylinder 14. When the stabilizing cylinder 14 rotates, the threaded rod 16 located inside will move upward. When the threaded rod 16 moves upward, the fixing block 22 located above will penetrate into the placement hole 17. When the fixing block 22 moves upward, it will push open the limiting blocks 21 on both sides and be located above the limiting blocks 21. Then, the operator turns the stabilizing cylinder 14 in the opposite direction, so that the fixing block 22 fits with the limiting block 21, fixing the fixing block 22, and thus fixing the entire stabilizing cylinder 14. When the entire stabilizing cylinder 14 needs to be replaced, the operator continuously rotates the stabilizing cylinder 14, causing the threaded rod 16 to continuously move upward, thereby driving the sliding block 26 located below to push up the two limiting blocks 21 and making the lower surface of the sliding block 26 fit with the limiting block 21. Then, the operator turns the stabilizing cylinder 14 in the opposite direction, causing the threaded rod 16 to move downward. Since the limiting block 21 presses against the bottom of the sliding block 26, it will drive the sliding block 26 to slide on the sliding rod 27 and make the upper surface of the sliding block 26 fit with the lower surface of the fixing block 22, making the sliding block 26 and the fixing block 22 close to each other. When the sliding block 26 and the fixing block 22 continue to move downward, they will push the limiting blocks 21 on both sides to move backward and cross the connection between the sliding block 26 and the fixing block 22, so that the entire stabilizing cylinder 14 and the threaded rod 16 are separated from the top column 12.
[0026] Furthermore, a baffle 4 is provided at the top of the top column 12. Warning pieces 13 are provided on both sides of the baffle 4. The warning pieces 13 have a reflective effect to improve the safety of vehicle driving at night. Stabilizing holes 8 are provided on both support columns 1. A plugging rod 2 is inserted inside the stabilizing hole 8. One end of the plugging rod 2 is fixedly installed with a protection plate 5, which is used to protect the vehicle and reduce the damage degree of the collision to the vehicle and the guardrail.
[0027] The working principle of the highway isolation fence structure provided by the present utility model is as follows:
[0028] When using the entire guardrail, the two support columns 1 are fixed. After the support columns 1 are fixed, the top column 12 and the bottom column 10 are fixed through the fixing rod 7, so as to fix the top column 12 and the bottom column 10.
[0029] After the fixation is completed, place the stabilizing cylinder 14 between the top column 12 and the bottom column 10, and then integrally insert the stabilizing cylinder 14 onto the bottom column 10 through the stabilizing column 15. After completion, the operator stabilizes the threaded rod 16 and then turns the stabilizing cylinder 14. When the stabilizing cylinder 14 rotates, the threaded rod 16 located inside will move upward. When the threaded rod 16 moves upward, the fixing block 22 located above will penetrate into the placement hole 17. When the fixing block 22 moves upward, it will push open the two limiting blocks 21 on both sides and be located above the limiting blocks 21. Then, the operator turns the stabilizing cylinder 14 in the opposite direction, so that the fixing block 22 fits with the limiting block 21, fixes the fixing block 22, and thus fixes the entire stabilizing cylinder 14.
[0030] When the entire stabilizing cylinder 14 needs to be replaced, the operator continuously rotates the stabilizing cylinder 14, so that the threaded rod 16 continuously moves upward, thereby driving the sliding block 26 located below to push up the two limiting blocks 21 and making the lower part of the sliding block 26 fit with the limiting blocks 21. Then, the operator turns the stabilizing cylinder 14 in the opposite direction, so that the threaded rod 16 moves downward. Since the limiting block 21 presses against the bottom of the sliding block 26, it will drive the sliding block 26 to slide on the sliding rod 27 and make the upper surface of the sliding block 26 fit with the lower surface of the fixing block 22, making the sliding block 26 closely adhere to the fixing block 22. When the sliding block 26 and the fixing block 22 continuously move downward, they will push the two limiting blocks 21 on both sides to move backward and cross the connection between the sliding block 26 and the fixing block 22, so that the entire stabilizing cylinder 14 and the threaded rod 16 are separated from the top column 12.
[0031] Compared with the related art, the highway isolation fence structure provided by the present utility model has the following
[0032] Beneficial effects:
[0033] The present utility model provides a highway isolation fence structure. When the entire stabilizing cylinder 14 needs to be replaced, the operator continuously rotates the stabilizing cylinder 14, so that the threaded rod 16 continuously moves upward, thereby driving the sliding block 26 located below to push up the two limiting blocks 21 and making the lower part of the sliding block 26 fit with the limiting blocks 21. Then, the operator turns the stabilizing cylinder 14 in the opposite direction, so that the threaded rod 16 moves downward. Since the limiting block 21 presses against the bottom of the sliding block 26, it will drive the sliding block 26 to slide on the sliding rod 27 and make the upper surface of the sliding block 26 fit with the lower surface of the fixing block 22, making the sliding block 26 closely adhere to the fixing block 22. When the sliding block 26 and the fixing block 22 continuously move downward, they will push the two limiting blocks 21 on both sides to move backward and cross the connection between the sliding block 26 and the fixing block 22, so that the entire stabilizing cylinder 14 and the threaded rod 16 are separated from the top column 12. Therefore, the stabilizing cylinder 14 can be quickly replaced individually, greatly improving the replacement efficiency of damaged railings.
