Technical Field

[0001] This utility model relates to the field of road barrier technology, and in particular to a road barrier rising bollard with a buffer mechanism. Background Technology

[0002] Rising bollards, also known as bollards, are used to restrict vehicle movement, thereby ensuring traffic order and the safety of important locations. Therefore, rising bollards are widely used in urban traffic, important national locations, highway toll stations, banks, airports, and other fields. With the continuous development of related technologies, there are also various types of rising bollards, such as pneumatic fully automatic rising bollards and hydraulic fully automatic rising bollards.

[0003] To reduce the damage to vehicles and protect the safety of drivers and passengers, it is necessary to improve the buffering effect of the device. However, the existing rising bollards have insufficient buffering effect, resulting in inadequate collision buffering protection for drivers and passengers. In response to this technical problem, this application proposes a rising bollard with a buffering mechanism. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-2 The present invention provides an embodiment of a road barrier lifting bollard with a buffer mechanism, comprising a bollard 1, a limiting ring 4 provided on the outer wall of the bollard 1, the limiting ring 4 being connected to a fixed ring 5 via a locking assembly, a housing 6 being fixedly connected to the outer wall of the fixed ring 5, a mounting base 7 being fixedly connected to the bottom of the housing 6, a plurality of mounting holes 8 being provided on the inner wall of the mounting base 7, a plurality of sliding grooves 9 being provided on the inner wall of the fixed ring 5, a plurality of buffer grooves 26 being provided at the bottom of the bollard 1, a buffer assembly being provided on the outer wall of the buffer grooves 26, a hydraulic rod 11 being provided on the bottom side of the bollard 1, the bottom of the hydraulic rod 11 being connected to the drive end of a motor 10, and the outer wall of the motor 10 being connected to the bottom side of the fixed ring 5 via a fixed bracket.

[0027] Specifically, the lifting column is installed on the inner wall of the fixing ring 5 by the locking component. The fixing ring 5 is installed inside the housing 6. The lifting column is fixed to the road by the mounting seat 7 on the bottom side of the housing 6. The mounting seat 7 is fixed by pouring concrete and the concrete solidifies in the mounting hole 8 inside the mounting seat 7. The column 1 is raised and lowered by the hydraulic rod 11 driven by the motor 10 on the inner wall of the fixing ring 5. When a vehicle collides, the buffer component in the buffer groove 26 on the bottom side of the column 1 can reduce the impact of the vehicle, thereby avoiding damage to the equipment.

[0028] Reference Figures 3-4The buffer assembly includes a buffer plate 12 located on the outer wall of the buffer groove 26. Multiple springs 15 are installed on the inner wall of the buffer plate 12. Slider 17s are fixedly connected to both the upper and lower sides of the buffer plate 12. Two sliders 13 are located on the front side of the buffer plate 12. A spring 14 is installed on the side of the two sliders 13 that are close to each other. The outer wall of slider 13 is slidably connected to a slide groove 9. The outer wall of slider 17 is slidably connected to a slide groove 16. One end of each spring 15 is connected to the buffer plate 12, and the other end is connected to the buffer groove 26. When a vehicle collides... When the column 1 is struck, the bottom buffer groove 26 of the column 1 will move closer to the buffer plate 12 on one side via the second spring 15. The buffer plate 12 is made of EPP material. The spring 15 and the buffer plate 12 can alleviate the instantaneous impact force. Then the spring 15 will restore the column 1. The bottom slider 13 is fixedly connected to the buffer plate 12. When the column 1 rises, the top slider 13 and the spring 14 can provide a buffer for the column 1, so that the equipment can rise at a uniform and stable speed while reducing the wear of the equipment.

[0029] Reference Figures 5-7 The locking assembly includes a connecting block 22 fixedly connected to the inner wall of the limiting ring 4. A protrusion 18 is provided on the inner wall of the connecting block 22. A connecting rod 23 is fixedly connected to the bottom side of the protrusion 18. A gear 25 is fixedly connected to the bottom side of the connecting rod 23. A rack 24 is meshed with the outer wall of the gear 25. A pin 20 is fixedly connected to the left side of the rack 24. The outer wall of the pin 20 is connected to a limiting groove 19. The limiting groove 19 is opened in the inner wall of the fixing ring 5. A fixing shell 21 is slidably connected to the outer wall of the pin 20. The outer wall of the rack 24 is slidably connected to the fixing shell 21. The outer wall of the fixing shell 21 is connected to the limiting ring 4. By inserting a special key, the protrusion 18 is turned, causing the protrusion 18 to drive the connecting rod 23 to rotate, thereby causing the rack 24 to slide on the fixing shell 21, and then causing the pin 20 in front of the rack 24 to move and insert into the limiting groove 19 in the fixing ring 5.

[0030] A pull ring 2 is provided on the top side of the column 1, which can be used to lift the column 1. A reflective strip 3 is installed on the top of the column 1 for warning purposes.

[0031] Working principle: By inserting a special key, the protrusion 18 is turned, causing the protrusion 18 to drive the connecting rod 23 to rotate, thereby causing the rack 24 to slide on the fixed shell 21, which in turn causes the pin 20 in front of the rack 24 to move and insert into the limiting groove 19 in the fixed ring 5, thus installing the lifting column on the inner wall of the fixed ring 5. The fixed ring 5 is installed inside the outer shell 6, and the lifting column is fixed to the road by the mounting seat 7 on the bottom side of the outer shell 6. By pouring concrete, the concrete solidifies in the mounting hole 8 in the mounting seat 7, which can fix the mounting seat 7. The motor 10 on the inner wall of the fixed ring 5 drives the hydraulic rod 11 to raise and lower the column 1. When a vehicle hits, the column 1 will cause the bottom buffer groove 26 to move closer to the buffer plate 12 on one side through the second spring 15. The buffer plate 12 is made of EPP material. The second spring 15 and the buffer plate 12 can relieve the instantaneous impact force. Then the second spring 15 restores the column 1. The bottom slider 13 is fixedly connected to the buffer plate 12, thereby avoiding damage to the equipment.
