Problems solved by technology

[0003] At present, similar products on the market are one-shaped brake levers, which have a single function and action. The starting position of the brake lever is 90 degrees perpendicular to the ground plane. The motor drives the brake lever to rotate on a vertical plane perpendicular to the ground plane, and the lever body swings. After 90 degrees, the position of the gate lever is parallel to the ground plane, so as to block the passage. However, when the position of the gate pole is parallel to the ground plane, if someone breaks through the passage forcibly, the gate pole will be violently impacted by external force, which will cause certain damage to the pedestrian's body. degree of damage, the brake lever itself will be damaged and lose its function, and the operator cannot be notified in a timely and effective manner when the brake lever is hit by an external force

[0004] In order to solve the above problems, some people design to use elastic materials to make the brake lever, and use the elasticity of the material of the brake lever to buffer the external force. When the position of the brake lever is parallel to the ground plane, if it is hit by an external force, the free end of the brake lever will produce a Displacement parallel to the ground plane, while the fixed end of the brake rod remains unchanged, the shape of the brake rod changes from a straight rod to a curved arc, but choosing a material with greater elasticity to make the brake rod will make it very easy for the external force to break through the brake rod. The basic function of the brake rod to block the passage is lost, and the brake rod is easy to break after the material with general elasticity is used to buffer the external force for many times, and the method of using the brake rod itself to buffer the external force is relatively expensive, and the service life of the product is relatively short, so it is not suitable for large mass production and application

[0005] In addition, someone designed to install a spring at the fixed end of the brake rod. When there is no external force, the spring is in a relaxed state. When the external force impacts the free end of the brake rod to produce a displacement parallel to the ground plane, the spring is compressed. After the external force disappears, the spring exerts pressure to move the brake. The rod resets, but in this scheme, when someone breaks through the passage forcibly, the brake rod will rebound quickly under the pressure of the spring after being deflected by the external force, which will cause damage to the people or objects passing through the passage, and the scope of application is small, especially Not suitable for use in densely populated places such as subways and bus entrances
