Description

Technical Field

[0001] This utility model belongs to the field of rising bollard technology, and more specifically, it relates to a manual rising bollard assembly. Background Technology

[0002] Rising bollards are widely used in urban traffic and surrounding areas, pedestrian streets, highway toll stations, airports, schools, banks, large clubs, parking lots, and many other places. By restricting the passage of vehicles, they effectively ensure traffic order and the safety of key facilities and locations.

[0003] Existing bollards typically operate by using a motor-driven oil pump to pressurize hydraulic oil. This oil then flows through pipes into a cylinder, pushing a piston to vertically raise or lower the bollard. However, this method is complex, has high production costs, and requires additional wiring to power the motor during installation, further increasing costs. Therefore, this study aims to improve upon existing structures and address their shortcomings by providing a manual bollard assembly that offers greater practical value. Utility Model Content

[0028] The driving mechanism includes a rotating shaft 11 rotatably connected to the top of the lifting column 2. The bottom end of the rotating shaft 11 passes through the first fixing plate 5 and the second fixing plate 7, and a driving plate 12 is fixedly installed on the bottom side of the fixing plate 12. One side of the driving plate 12 abuts against one side of one of the locking ends, so that when the driving plate 12 is rotated, the locking plate 9 can be flexibly rotated, thereby unlocking. Both ends of the rotating shaft 11 are provided with steps. The top step abuts against the bottom end of the first fixing plate 5, and the bottom step abuts against the top end of the second fixing plate 7, so as to ensure that the rotating shaft 11 can be stably installed and can rotate stably.

[0029] The top of the rotating shaft 11 extends through the lifting column 2 and has an internal hexagonal hole, which allows the rotating shaft 11 to be easily rotated using an external hexagonal tool during use.

[0030] The bottom outer side of the connecting rod 8 is engaged with a retaining spring 14, the top side of the retaining spring 14 abuts against the bottom side of the locking plate 9 to prevent the locking plate 9 from falling off the connecting rod 8; and the bottom end of the connecting rod 8 is also provided with a step, and the upper and lower ends of the locking plate 9 are respectively provided with the step and the retaining spring 14, thereby forming a stable limit so that it can rotate stably.

[0031] The connecting column 6 is fitted with a torsion spring 13 on its outer side.
