[0031] Example

[0032] Please see Figures 1-5As shown, this utility model provides a splicing security camera connection structure technical solution: A splicing security camera connection structure includes a mounting head 1, the upper end of which is fixedly connected to a positioning component. A plurality of housings 2 for mounting camera lenses are mounted on the lower end of the mounting head 1. A docking component 3 connects the housings 2 and the mounting head 1. A drive motor 4 is mounted inside the mounting head 1. An adjustment component 5 for adjusting the lens viewing angle is mounted inside the housings 2 at the lower end of the drive motor 4. A controller 6 is mounted on one side of the housings 2, and the controller 6 is wirelessly connected to an external remote control. The adjustment component 5 includes a gear 501, an electromagnetic block 504, and a rubber ring 509. The gear 501 is movably mounted in a through hole inside the housings 2 and can slide up and down relative to the housings 2. A toothed sleeve 502 matching the teeth of the gear 501 is mounted on the lower end of the gear 501 and the output end of the drive motor 4. A coupling component 503 for mutual connection is also mounted on the gear 501 and the toothed sleeve 502. Electromagnetic blocks 504 are symmetrically installed inside the housing 2. A push rod 505 is slidably connected to a groove inside the housing 2 on the inner side of the electromagnetic blocks 504. The end of the push rod 505 has a toothed groove that matches the teeth of the toothed rod 501. An arc-shaped groove 506 is formed on the outer side of the housing 2 on the electromagnetic blocks 504. An elastic positioning piece 507 is movably installed within the arc-shaped groove 506. Permanent magnet blocks 508 are fixedly connected to the push rod 505 and the elastic positioning piece 507 on the side adjacent to the electromagnetic blocks 504. The permanent magnet blocks 508 are slidably connected in the grooves on both sides of the housing 2. After receiving a wireless signal, the controller 6 can change the current direction of the permanent magnet blocks 508. A rubber ring 509 is adhered to the docking assembly 3 above the arc-shaped groove 506.

[0033] During the operation of the security camera, the electromagnetic block 504 remains energized. When the electromagnetic block 504 is energized, it generates a repulsive force on the permanent magnet block 508 at the end of the push rod 505, and an attractive force on the permanent magnet block 508 at the end of the elastic positioning piece 507. At this time, the push rod 505 is pushed out, and the tooth groove meshes with the teeth of the toothed rod 501. The drive motor 4 starts, allowing the camera housing 2 to adjust its viewing angle. When the electromagnetic block 504 changes its current direction under the adjustment of the controller 6, it generates an attractive force on the permanent magnet block 508 at the end of the push rod 505, and a repulsive force on the permanent magnet block 508 at the end of the elastic positioning piece 507. At this time, the elastic positioning piece 507 is pushed out along the arc groove 506. After the end of the elastic positioning piece 507 leaves the arc groove 506, it presses against the rubber ring 509. At this time, the camera housing 2 is positioned by the friction between the elastic positioning piece 507 and the rubber ring 509. The camera can stably perform monitoring and framing operations.

[0034] By adjusting component 5, the framing angles of the interlocked camera lenses can be independently controlled and locked, and the camera viewing angle adjustments will not interfere with each other, improving the operability and flexibility of camera angle adjustment. In addition, in conjunction with docking component 3, it ensures that the adjustment and locking functions of the cameras that are later expanded will not be affected.

[0035] The docking assembly 3 includes a main conductive slip ring 301, a secondary conductive slip ring 303, and a secondary positioning ring 304. The upper end of the main conductive slip ring 301 is connected to the lower end face of the mounting head 1. The outer side of the main conductive slip ring 301 is rotatably connected to the main positioning ring 302 via ball bearings. The upper end of the main positioning ring 302 is fixedly connected to the lower end face of the mounting head 1. The housing 2 is mounted on the lower end face of the main conductive slip ring 301. When the housing 2 rotates the lower end of the main conductive slip ring 301, it will not interfere with the mounting head 1 or the main positioning ring 302. The upper end of the secondary conductive slip ring 303 is bolted to the lower end of the housing 2 via a mounting base. The lower end of the secondary conductive slip ring 303 is fixedly connected to the extended housing 2. The secondary positioning ring 304 is rotatably connected to the outside of the secondary conductive slip ring 303. A fixing rod 305 connects the secondary positioning ring 304 and the main positioning ring 302. A rubber ring 509 is bonded to the mounting groove at the lower end of the main positioning ring 302 and the secondary positioning ring 304. When the extended housing 2 drives the lower end of the secondary conductive slip ring 303 to rotate, it will not interfere with the housing 2 connected above or below.

[0036] After the power cord is connected to the mounting head 1, it is connected to each housing 2 through the main conductive slip ring 301 and the auxiliary conductive slip ring 303 to establish a circuit.

[0037] A set of camera extension components consists of a secondary conductive slip ring 303, a secondary positioning ring 304, a fixing rod 305, and a housing 2. When it is necessary to extend the camera, the fixing rod 305 above the camera is connected to the lowermost secondary positioning ring 304, and the secondary conductive slip ring 303 is bolted to the housing 2 that has been installed above. At the same time, the gear 501 is pushed up and rotated for adjustment until the gear 501 enters the gear sleeve 502 and they are attracted to each other. The adjustment component 5 is then docked.

[0038] By using the docking component 3, the number of cameras in the splicing security camera can be flexibly expanded and adjusted, breaking the limitation of the two-way monitoring viewing angle. After the cameras are expanded, 360-degree full monitoring can be achieved. If the viewing angle of a single camera is less than 120 degrees, it can be further expanded to ensure the viewing angle requirements.

[0039] The coupling element 503 is a magnet. The coupling element 503 is installed on the upper end of the gear 501 and the inner side of the gear sleeve 502. The magnet can not only meet the connection requirements of the gear 501 and the gear sleeve 502, but also make disassembly and docking more convenient in the future.

[0040] The two ends of the through hole on the inner side of the housing 2 are provided with limiting rings 201 that match the toothed sleeve 502. The limiting rings 201 can prevent the toothed rod 501 of the extended camera that is not installed from falling out of the housing 2.

[0041] The lower end of the fixing rod 305 is rotatably connected to the secondary positioning ring 304. The lower end faces of the main positioning ring 302 and the secondary positioning ring 304 are threadedly connected to the upper end of the fixing rod 305 through threaded holes. The threaded connection can ensure the convenience of installation and removal when expanding the camera later.

[0042] The working principle of this utility model is as follows:

[0043] When an extended camera is needed, the fixed rod 305 above the extended camera is threadedly connected to the lowermost secondary positioning ring 304, and the mounting base above the secondary conductive slip ring 303 is bolted to the upper installed housing 2. Simultaneously, push the gear 501 upwards and rotate it until the gear 501 enters the gear sleeve 502 and they attract each other, completing the docking of the adjustment assembly 5. At this point, the electromagnetic block 504 can be energized to adjust the angle of the extended camera. When energized, the electromagnetic block 504 generates a repulsive force on the permanent magnet block 508 at the end of the push rod 505 and an attractive force on the permanent magnet block 508 at the end of the elastic positioning piece 507. The push rod 505 is pushed out, and the tooth groove meshes with the teeth of the gear 501. Since the gear 501 is connected to the output end of the drive motor 4 via a coupling 503, the rotation of the drive motor 4 allows for adjustment of the viewing angle of the extended camera's housing 2.

[0044] When the viewing angle of a certain housing 2 needs to be adjusted, the current direction of the electromagnetic block 504 is changed, which generates an attractive force on the permanent magnet block 508 at the end of the push rod 505 and a repulsive force on the permanent magnet block 508 at the end of the elastic positioning piece 507. At this time, the push rod 505 separates from the rack 501, and the elastic positioning piece 507 is pushed out along the arc groove 506. After the end of the elastic positioning piece 507 leaves the arc groove 506, it presses against the rubber ring 509. At this time, the housing 2 is positioned by the friction between the elastic positioning piece 507 and the rubber ring 509. The camera can stably perform monitoring and viewing operations.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
