Description

Technical Field

[0002] The barrier gate mechanism is an important part of traffic control equipment and is widely used in places such as parking lots, highways, and bridges. Its function is to raise or lower the barrier gate when needed to control the entry and exit of vehicles. With the development of technology, the technology of the barrier gate mechanism is also constantly advancing to meet higher safety and efficiency requirements. The barrier gate mechanism is mainly composed of a motor, a speed reducer, a controller, and a transmission device. The transmission device generally uses chain and gear transmission to achieve the lifting and other movements of the mechanism. However, when the above equipment is in use, there is a lack of a structure for limiting and protecting the barrier gate crossbar. Therefore, when the barrier gate crossbar rises or falls, the transmission device rotates, and at this time, the shaft rotates synchronously. At this time, due to the gravity of the crossbar itself, it is easy to cause the crossbar to rise or fall beyond the range, and thus it is easy to cause damage to the motor.

A buffer mechanism is installed on the bottom surface of the support plate 1. The other end of the shaft rod 8 is installed with a cross bar 13. The surface of the shaft rod 8 is connected to an adjusting ring 14. One side of the adjusting ring 14 is connected to a limit block 15. The surface of the support plate 1 is connected to a limit seat 16. The other side of the adjusting ring 14 is connected to a limit plate 17. The surface of the support plate 1 is connected to a vertical plate 18.

[0024] The motor 2 is a forward and reverse motor. The linkage arm 5, the receiving arm 6 and the straight plate 7 are all rotatably connected through a rotating shaft.

[0025] By using the motor 2, it is convenient to adjust the cross bar 13 to rise or fall.

[0026] The buffer mechanism includes a side plate 10, a bottom rod 11 and a buffer spring 12. The side plate 10 is connected to the bottom surface of the support plate 1. The bottom of the inner side of the side plate 10 is connected to the bottom rod 11. The surface of the bottom rod 11 is connected to the buffer spring 12. The other end of the buffer spring 12 is connected to the connecting block 9.

[0027] By rotating the connecting block 9, it is convenient to drive the buffer spring 12 to stretch, and thus it is convenient to protect the shaft rod 8.

[0028] The bottom end of the limit block 15 is provided with a foot post made of silica gel, and the foot post at the bottom end of the limit block 15 is in contact with the limit seat 16.
