[0002] The wide-angle dual camera is mainly used to take photos and videos. Its wide-angle field of view makes the shooting effect more outstanding and can be used for some scenes with a large depth of field. At the same time, the wide-angle dual camera can also be used for highway vehicle model identification. Two sets of wide-angle dual cameras, one installed at the toll island to identify the rear of the vehicle, and the other installed in the toll lane to identify the side of the vehicle. The purpose is to assist the toll collector in the booth to more intuitively identify the rear and side of the vehicle, and determine whether it is a container vehicle, thereby realizing the recognition of highway vehicle models.

[0003] Most of the existing highway vehicle type recognition devices are fixed with bolts when in use. When disassembly and maintenance are required, tools are required, but the disassembly efficiency is low, which affects the maintenance efficiency.

[0004] Patent document CN212064197U discloses a vehicle type recognition device for a highway toll station, "including at least one recognition component arranged on a toll island; the recognition component includes a first rotating motor fixed on the top of a first base; the output end of the first rotating motor is connected to the main screw, and the main screw is linked to the slave screw through a synchronous belt; the main screw and the slave screw are respectively sleeved with a main screw nut and a slave screw nut; the main screw nut and the slave screw nut are respectively fixed to the two ends of the second base, and the second rotating motor is fixedly installed in the second base; the output shaft of the second rotating motor is connected to the mounting seat, and the induction motor is fixedly installed in the mounting seat; the camera is fixed on the output shaft of the induction motor; the camera, the first rotating motor, and the second rotating motor are all connected to the controller; the controller is connected to the relay, the motor controller, the motor driver and the induction motor in turn", however, the vehicle type recognition device for a highway toll station in the above-mentioned public document mainly considers the problem of remotely adjusting the camera, but does not consider the problem of facilitating the disassembly and maintenance of the camera. Therefore, it is necessary to develop a highway vehicle type recognition device. Utility Model Content

[0005] The utility model aims to provide a highway vehicle type recognition device to solve the technical problem that it is inconvenient to quickly disassemble and repair a camera in the above background technology.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model uses the installed card slot and slide slot. When the wide-angle dual camera needs to be disassembled for maintenance, the wide-angle dual camera is pushed to slide upward, which will drive the position of the slide slot to move. After the limit block is pressed by the outside, since the limit block is arc-shaped, the limit block will move into the inside of the slide slot and separate from the groove, so that the wide-angle dual camera is no longer limited, and the wide-angle dual camera can be quickly disassembled, achieving the purpose of easy disassembly, facilitating the disassembly and maintenance of the wide-angle dual camera, and improving the maintenance efficiency;

When clamping and limiting the wire connected to the highway vehicle model recognition device, after placing the wire in the limit frame 14, rotating the adjusting bolt 17 will move the position of the threaded barrel 16. When the threaded barrel 16 moves, it will push the clamping block 15 to move. When the clamping block 15 moves, it will limit and clamp the wires inside the limit frame 14, thereby achieving the purpose of limiting the wires, effectively preventing the wires from being accidentally detached due to external factors, affecting the use of the highway vehicle model recognition device, and when the wide-angle dual camera 1 needs to be disassembled and maintained, the wide-angle dual camera 1 is pushed to slide upward, which will drive the position of the slide groove 6 to move.
