Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] A preferred embodiment of a license plate recognition camera core provided by the utility model is as follows: Figures 1 to 5 As shown: a license plate recognition camera movement, including a shell 1, a top plate 2 is attached to the top of the shell 1, a screw 3 is engaged with the top of the top plate 2, the surface of the shell 1 is connected to a panel 4 through the screw 3, the inside of the shell 1 is connected to a movement 5 through the screw 3, an adjustment mechanism 6 is provided on the side of the shell 1, a mounting plate 7 is connected to the side of the shell 1 through the adjustment mechanism 6, a fixing column 8 is fixedly connected to the bottom of the mounting plate 7, a fixing bolt 9 passes through the surface of the fixing column 8, a pillar 10 is embedded in the bottom of the fixing column 8, and a bracket 11 is fixedly connected to the bottom of the pillar 10.

[0028] In this embodiment, the corners of the top plate 2 are arc-shaped, the panel 4 is transparent, the movement 5 is installed inside the outer shell 1 by screws 3, and then the outer shell 1, the top plate 2 and the panel 4 are assembled by screws 3. Because the surface of the top plate 2 is arc-shaped, the staff will not scratch their hands during assembly, and the surface of the panel 4 is transparent, which will not affect the normal operation of the camera on the surface of the movement 5.

[0029] In this embodiment, the fixing column 8 is hollow, and three groups of fixing grooves are provided on the surface of the fixing column 8, and one group of fixing grooves is provided on the surface of the pillar 10. Because the fixing column 8 is hollow, the pillar 10 can be embedded in the fixing column 8 so that the fixing grooves on the surface of the pillar 10 correspond to any group of fixing grooves on the surface of the fixing column 8, and then the fixing bolts 9 are passed through the fixing grooves on the surfaces of the pillar 10 and the fixing column 8, and the fixing bolts 9 are tightened to connect the pillar 10 with the fixing column 8, thereby achieving the purpose of installing the camera. When the height of the camera needs to be adjusted, the fixing bolts 9 can be removed, and then the fixing column 8 can be moved up and down. When the fixing grooves at the bottom of the surface of the fixing column 8 correspond to the fixing grooves on the surface of the pillar 10, the height of the camera is the highest at this time, thereby achieving the purpose of facilitating the installation of the camera, and then achieving the purpose of adjusting the height of the camera without re-drilling and positioning.

[0030] Example 2

[0031] Based on Example 1, a preferred embodiment of a license plate recognition camera core provided by the present invention is as follows: Figures 1 to 5 As shown: the adjustment mechanism 6 includes a screw rod 61, a slider 62, a rack 63, a gear 64, a limit column 65 and a transmission column 66. The inner wall of the mounting plate 7 is rotatably connected to the screw rod 61, the surface of the screw rod 61 is threadedly connected to the slider 62, the top of the slider 62 is fixedly connected to the rack 63, the top of the rack 63 is meshed with the gear 64, and the side of the gear 64 is penetrated by the transmission column 66.

[0032] In this embodiment, the movement trajectory of the rack 63 is consistent with the movement trajectory of the slider 62. The rack 63 forms a moving structure through the slider 62. Because the slider 62 is meshed with the screw rod 61, when the screw rod 61 rotates, it will drive the slider 62 to slide backward. At this time, the rack 63 fixedly connected to the slider 62 will move backward accordingly and drive the gear 64 meshing with it to rotate counterclockwise.

[0033] In this embodiment, two groups of limiting columns 65 are provided, and the inner wall of the mounting plate 7 is provided with a ring-shaped slide groove. The two groups of limiting columns 65 are embedded in the ring-shaped groove of the mounting plate 7. Because the two groups of limiting columns 65 are fixedly connected to the gear 64, when the gear 64 rotates, it will drive the two groups of limiting columns 65 to slide in the ring-shaped slide groove on the inner wall of the mounting plate 7 and play a certain limiting role on the gear 64.

[0034] In this embodiment, the gear 64 is fixedly connected to the transmission column 66, one end of the transmission column 66 is rotationally connected to the mounting plate 7, and the other end of the transmission column 66 is fixedly connected to the housing 1. Because the transmission column 66 is fixedly connected to the gear 64, when the gear 64 rotates, it will drive the transmission column 66 to rotate counterclockwise. At this time, the housing 1 fixedly connected to the transmission column 66 will rotate counterclockwise accordingly. When it rotates to a suitable angle, the screw rod 61 can be stopped from rotating, so as to achieve the purpose of adjusting the angle of the housing 1, thereby achieving the purpose of adjusting the angle of the camera.

[0035] The working principle and use process of the utility model are as follows: first, the movement 5 is installed inside the housing 1 by means of screws 3, and then the housing 1, the top plate 2 and the panel 4 are assembled by means of screws 3. Because the surface of the top plate 2 is arranged in an arc shape, the staff will not scratch their hands during assembly, and the surface of the panel 4 is arranged in a transparent manner, which will not affect the normal operation of the camera on the surface of the movement 5.

[0036] Then, because the fixing column 8 is hollow, the pillar 10 can be embedded in the fixing column 8, so that the fixing groove on the surface of the pillar 10 corresponds to any group of fixing grooves on the surface of the fixing column 8, and then the fixing bolt 9 is passed through the fixing grooves on the surfaces of the pillar 10 and the fixing column 8, and the fixing bolt 9 is tightened, so that the pillar 10 and the fixing column 8 can be connected, thereby achieving the purpose of installing the camera. When it is necessary to adjust the height of the camera, the fixing bolt 9 can be removed, and then the fixing column 8 can be moved up and down. When the fixing groove at the bottom end of the surface of the fixing column 8 corresponds to the fixing groove on the surface of the pillar 10, the height of the camera is the highest at this time, thereby achieving the purpose of facilitating the installation of the camera, and then achieving the purpose of adjusting the height of the camera without re-drilling and positioning;

[0037] When the camera angle needs to be adjusted, the screw rod 61 can be manually rotated counterclockwise. Because the slider 62 is meshed with the screw rod 61, when the screw rod 61 rotates, the slider 62 will be driven to slide backward. At this time, the rack 63 fixedly connected to the slider 62 will move backward accordingly, and drive the meshing gear 64 to rotate counterclockwise. Because the two sets of limit posts 65 are fixedly connected to the gear 64, when the gear 64 rotates, it will drive the two sets of limit posts 65 to slide in the annular groove on the inner wall of the mounting plate 7 and play a certain limiting role on the gear 64. Because the transmission post 66 is fixedly connected to the gear 64, when the gear 64 rotates, it will drive the transmission post 66 to rotate counterclockwise together. At this time, the housing 1 fixedly connected to the transmission post 66 will rotate counterclockwise accordingly. When it rotates to a suitable angle, the screw rod 61 can be stopped from rotating, so as to achieve the purpose of adjusting the angle of the housing 1, thereby achieving the purpose of adjusting the camera angle.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
