Description

Technical Field

[0001] The utility model relates to the technical field of parking locks, in particular to a curb lock. Background Art

[0002] At present, due to the annual increase in the number of cars in cities, the pressure of urban parking is increasing, and the problem of parking difficulty is becoming increasingly serious. In order to alleviate the pressure of urban parking, more and more urban roads have been developed into side-to-side paid parking spaces, but the existing urban transportation service infrastructure is still imperfect. There are two main ways to charge parking fees in the traditional way. One is to use manual charging, which has a relatively high labor cost and is prone to omissions and irregular charging. The other is to use an unattended intelligent parking system, that is, relying on a high-definition camera with built-in powerful image recognition + a mobile management terminal, automatically recording and notifying parking users to pay. This method also has the problem of expensive camera systems and high layout costs. In addition, since there is no parking lock, payment depends entirely on the self-consciousness of parking users and cannot be mandatory.

[0003] The utility model patent application with application number 202322392927.1 provides a track curb lock that can be directly installed on the curb of a side parking space, including a track and a control mechanism and a swing arm mechanism installed in the track. One end of the swing arm mechanism is rotatably connected to the control mechanism, and under the action of the control mechanism, the other end is rotated 90° around the connection point to achieve a vertical setting with the track, blocking the front and rear wheels of the car in the parking space to achieve a car locking function.

[0004] The connection between the swing arm mechanism and the control mechanism of this structure is a rigid rotational connection. When there is a foreign object blocking the road surface, the swing arm mechanism will be hit by the foreign object during the rotation process. Multiple impacts will cause the connection to deform and become unusable. Or if some toll-doing vehicles directly run over the swing arm mechanism, the connection will also be deformed and fail. Therefore, the existing structure needs to be further improved. Utility Model Content

The ultrasonic radar 3-3 monitors the vehicle, thereby sending information to the rotary drive motor 3-1, so that the rotary drive motor 3-1 works and drives the swing arm mechanism 2 to move. Two micro switches 3-4 fixedly installed on the motor box 3-2 are provided on the side of the motor shaft. The two micro switches 3-4 correspond to the rotation limit positions of the connecting assembly 2-1 respectively, so as to reliably limit the extreme rotation position of the swing arm mechanism 2, which can not only realize the precise control of the swing amplitude of the swing arm mechanism 2, but also further improve the safety of use.

Specifically, the top of the barrier arm body 2-2-1 is evenly provided with mounting holes corresponding to the anti-car nails 2-4 along the length direction. The anti-car nails 2-4 include a fixing member 2-4-1 vertically fixed between the top and bottom of the inner wall of the barrier arm body 2-2-1, and a telescopic hole coaxially arranged with the mounting hole is arranged in the middle of the fixing member 2-4-1.
