Description

Technical Field

[0001] The utility model relates to a barrier gate, in particular to a barrier gate which has a simple transmission structure and can adjust the direction of a barrier rod and can be switched left and right. Background Art

[0002] With the continuous development of the automobile industry and the increasing number of cars, higher requirements are also put forward for the performance of the gate. The gate is a control device for vehicle passages and is widely used in places where vehicle entrances and exits need to be controlled. The gate must use a reduction mechanism to reduce the power output by the motor to drive the gate rod to swing. The current reduction mechanism often uses multi-stage reduction. Generally, the last stage of the reduction structure is a gear installed on the swing rod shaft. Because the gear is round, and the swing rod shaft is installed on the gear axis, this will cause the gate rod to be installed in the middle and upper part of the main box. The main box is relatively high, which will be inconvenient to install in some places. At the same time, when the gate is installed or used in the actual place, it is often necessary to switch the direction of the gate rod (i.e. left or right) to meet the use requirements of different places. The previous method is mainly to replace the movement and parts. Generally, the manufacturer's personnel are required to bring the movement or parts to the site for processing, which is very inconvenient. Summary of the invention
