Description

Technical Field

[0001] The utility model relates to the technical field of car stoppers, in particular to a telescopic variable channel gate. Background Art

[0002] The barrier gate, also known as the vehicle blocker, is a channel entrance and exit management device specially used to restrict the travel of motor vehicles on the road. It is now widely used in highway toll stations and parking systems to manage vehicle passages and to manage the entry and exit of vehicles.

[0003] Most of the existing gates are located in the middle of the aisle to identify and block vehicles passing through the aisle. When there are many vehicles on the aisle, the lifting arm will automatically identify and automatically rise and fall. When the first vehicle passes through the gate, the lifting arm begins to fall back. At this time, due to camera recognition or induction coil sensing the second vehicle, the lifting arm needs to stop falling to prevent the lifting arm from hitting the vehicle. At this time, the motor controlling the lifting arm is in an emergency stop state, which causes the lifting arm to increase the inertia generated by the end of the lifting arm during movement due to its long length in mid-air, resulting in a large amplitude of shaking. In order to ensure the passing efficiency, the lifting arm is not allowed to calm down and is then driven by the motor to open upward again. During the second opening process of the lifting arm, the lifting arm is still in a shaking state. Frequent continuous rising and falling will reduce the practical life of the lifting arm. For this reason, we propose a telescopic variable channel gate. Utility Model Content

After the railing 21 is fully opened, the telescopic rod 24 compresses the spring 23 located inside the telescopic slot 22, shortening the overall length of the railing 21 and the telescopic rod 24, thereby reducing the jitter of the railing 21 during continuous lifting and lowering, extending the service life of the lifting and lowering rod, and realizing the rapid release of vehicles.
