Description

Technical Field

[0001] This utility model belongs to the technical field of supplementary lighting devices, and more specifically, it relates to a supplementary lighting device for video surveillance security cameras. Background Technology

[0002] In the field of video surveillance, the supplementary lighting device of security cameras is a key component to ensure the clarity of monitoring images at night or in low-light environments. It can provide clearer images for surveillance cameras to meet better usage needs.

[0003] Most existing supplementary lights are fixedly installed on one side of the camera. In actual use, it is difficult to dynamically adjust the lighting angle of the supplementary lights according to the actual monitoring scene, which can easily lead to problems such as reflections, shadows, or uneven lighting, affecting the monitoring effect. Therefore, in view of this, this paper studies and improves the existing structure and its shortcomings, and provides a supplementary lighting device for video surveillance security cameras, aiming to achieve a more practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a supplementary lighting device for video surveillance security cameras, which is achieved by the following specific technical means:

[0005] A supplementary lighting device for a video surveillance security camera includes a housing. Two sets of slide rails are fixedly installed inside the housing. A movable plate is connected to the outer sides of both sets of slide rails via sliding blocks. Buffer components are provided inside the housing at both ends of the two sets of slide rails. A through groove is formed at the bottom end of the movable plate on one side of each set of slide rails. A fixed shaft is rotatably connected inside the housing to one side of one set of through grooves. One end of the fixed shaft protrudes from the corresponding through groove and is fitted with a camera. A second fixed shaft is rotatably connected inside the housing to one side of the other set of through grooves. One end of the second fixed shaft protrudes from the corresponding through groove and is fixedly fitted with a base plate. A supplementary light is installed on one side of the bottom end of the base plate.

[0006] As a preferred embodiment of this utility model, an electric push cylinder is fixedly installed inside the housing, and a connecting block corresponding to the output end of the electric push cylinder is fixedly installed on one side of the moving plate, and the output end of the electric push cylinder is fixedly connected to the connecting block.

[0007] As a preferred embodiment of this utility model, a rack is fixedly installed at the top of the movable plate and on one side of the two sets of through slots, and gears are fixedly installed inside the housing and on the outside of the first fixed shaft and the second fixed shaft, and the gears and racks mesh with each other.

[0008] As a preferred technical solution of this utility model, a limiting groove is provided at the top of the movable plate and on both sides of the two sets of through grooves. A limiting ring is fixedly installed on the outer side of the first fixed shaft and the second fixed shaft, and the limiting ring is located directly below the gear. The limiting ring is slidably connected inside the limiting groove.

[0009] As a preferred technical solution of this utility model, the buffer assembly includes four sets of side plates installed inside the housing. A telescopic rod is fixedly installed on one side of each of the four sets of side plates. A contact plate is fixedly installed at one end of each telescopic rod, and one end of each contact plate abuts against one side of the moving plate. A spring is fitted on the outside of each telescopic rod, and the two ends of the spring abut against the side plate and the contact plate, respectively.

[0010] As a preferred embodiment of this utility model, mounting plates are symmetrically connected to both sides of the housing, and mounting holes are provided in the center of each mounting plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention uses an electric pusher cylinder to drive a moving plate along a slide rail, and in conjunction with gear and rack transmission, enables the camera and supplementary light to rotate synchronously around fixed axis one and fixed axis two. This ensures that the direction of the supplementary light is always consistent with the rotation direction of the camera, improving the reliability of the linkage adjustment and the imaging effect of night monitoring. It avoids problems such as reflection, shadows, or uneven lighting in the monitoring image, and meets the real-time dynamic adjustment requirements in remote monitoring scenarios. By setting a buffer component, it can absorb and weaken the impact force, avoid structural deformation caused by rigid collisions, and thus protect the internal mechanical structure and key components of the device, improving the safety and service life of the device.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] This utility model provides a supplementary lighting device for a video surveillance security camera, including a housing 1. Two sets of slide rails 2 are fixedly installed inside the housing 1. A movable plate 3 is connected to the outer sides of both sets of slide rails 2 via sliding blocks. Buffer components 4 are provided inside the housing 1 at both ends of the two sets of slide rails 2. A through groove 5 is provided at the bottom end of the movable plate 3 on one side of both sets of slide rails 2. A fixed shaft 6 is rotatably connected inside the housing 1 to one side of one set of through grooves 5. One end of the fixed shaft 6 protrudes from the corresponding through groove 5 and is fitted with a camera 7. A fixed shaft 8 is rotatably connected inside the housing 1 to one side of the other set of through grooves 5. One end of the fixed shaft 8 protrudes from the corresponding through groove 5 and is fixedly installed with a base plate 9. A supplementary light 10 is installed on one side of the bottom end of the base plate 9.

[0026] The housing 1 is equipped with an electric push cylinder 11, and a connecting block 12 corresponding to the output end of the electric push cylinder 11 is fixedly installed on one side of the moving plate 3. The output end of the electric push cylinder 11 is fixedly connected to the connecting block 12, which realizes the automated driving of the moving plate 3 without the need for manual on-site operation. At the same time, compared with manual adjustment, the electric push cylinder 11 can accurately control the displacement of the moving plate 3, thereby accurately adjusting the rotation angle of the camera 7 and the supplementary light 10, meeting the needs of real-time adjustment of the supplementary light angle in different monitoring scenarios.

[0027] Among them, a rack 13 is fixedly installed on the top of the movable plate 3 and on one side of the two sets of through slots 5. Gears 14 are fixedly installed on the outer sides of the first fixed shaft 6 and the second fixed shaft 8. The gears 14 and the rack 13 mesh with each other, which can ensure that the camera 7 and the supplementary light 10 always remain synchronized during the adjustment process. This ensures that the supplementary light 10 can always provide the camera 7 with the best angle of supplementary light, effectively improving the uniformity of illumination and the overall quality of the monitoring image.

[0028] The movable plate 3 has limit grooves on its top and on both sides of the two sets of through grooves 5. Limit rings 15 are fixedly installed inside the housing 1 and on the outside of the fixed shaft 6 and the fixed shaft 8. The limit rings 15 are located directly below the gear 14 and are slidably connected inside the limit grooves. This effectively limits the radial displacement of the fixed shaft 6 and the fixed shaft 8 during rotation, ensuring that the gear 14 and the rack 13 always remain in mesh, thus enhancing the rigidity and stability of the overall mechanism. At the same time, it ensures that the camera 7 and the fill light 10 maintain precise angle adjustment performance during long-term use.

[0029] The buffer assembly 4 includes four sets of side plates 401 installed inside the housing 1. A telescopic rod 402 is fixedly installed on one side of each of the four sets of side plates 401. A contact plate 403 is fixedly installed at one end of each telescopic rod 402, and one end of each contact plate 403 abuts against one side of the moving plate 3. A spring 404 is fitted on the outside of each telescopic rod 402, and the two ends of the spring 404 abut against the side plate 401 and the contact plate 403 respectively. This can absorb and weaken the impact force, avoid structural deformation caused by rigid collision, and thus protect the internal mechanical structure and key components of the device, improving the safety and service life of the device.

[0030] The housing 1 has mounting plates 16 symmetrically connected to both sides. Each mounting plate 16 has a mounting hole in its center. The symmetrical design of the mounting plates 16 and the positioning function of the central mounting holes ensure the balance and stability of the device during installation, meeting the installation requirements of diverse security monitoring scenarios.

[0031] The working principle of this embodiment:

[0032] When using the supplementary lighting device, firstly, the device is fixed to the monitoring pole, wall, or other supporting structure using bolts or screws via the mounting plates 16 on both sides of the housing 1; then, the camera 7 and the supplementary light 10 are fixed to the bottom of the fixed shaft 6 and the base plate 9 respectively, and both are adjusted to a suitable tilt angle for monitoring; when it is necessary to turn the camera 7 and the supplementary light 10, the electric push cylinder 11 is activated. The output end of the electric push cylinder 11 pushes the connecting block 12 and the moving plate 3 connected to the connecting block 12 to slide horizontally along the slide rail 2. While the moving plate 3 slides, the rack 13 at its top moves synchronously with the sliding plate 3 and moves along the fixed shaft. With the gear 14 on the outer side of the fixed shaft 6, the linear motion is converted into the rotational motion of the gear 14. The fixed shaft 6 drives the camera 7 to rotate, and the fixed shaft 8 drives the base plate 9 and the supplementary light 10 to rotate. Since the transmission ratio of the gear 14 and the rack 13 is the same, their rotation angles are the same and their directions are synchronized, ensuring that the lamp cover of the supplementary light 10 and the lens of the camera 7 are always horizontally aligned, realizing the coordinated adjustment of the supplementary light angle and the monitoring angle. When the moving plate 3 is reciprocating, it is buffered by the telescopic rod 402, the spring 404 and the contact plate 403 on one side of the side plate 401, which improves the safety and stability of the device.
