Description

Technical Field

[0001] This utility model relates to the field of installation technology for photographic and video equipment and security equipment, specifically to an adjustable pan-tilt head for a camera. Background Technology

[0002] In security monitoring, video conferencing, and professional photography, the pan-tilt head is a key component connecting the camera to a support surface (such as a wall, ceiling, or tripod). Its main function is to support the camera and adjust its shooting angle (such as horizontal rotation "tilt" and vertical tilt "nod"). Most simple manual pan-tilt heads on the market currently use a simple friction locking structure for angle locking, that is, fixing the angle by tightening a knob and utilizing the friction between two smooth contact surfaces. While this structure is simple to manufacture, it has the following shortcomings: (1) Poor locking reliability: Pure friction is easily weakened by environmental factors (such as temperature changes, oil stains). When the camera is heavy or the installation environment is subject to continuous vibration (such as wind or passing vehicles), the torque generated by gravity will often overcome the friction, causing the camera to "droop" or "tilt", causing the monitoring screen to deviate from the preset area.

[0003] (2) Difficult to operate: In order to ensure sufficient locking force, users often need to use a lot of force to tighten the knob, resulting in a poor operating experience and easy damage to the knob components.

[0004] (3) Inconvenient disassembly and assembly: Traditional pan-tilt units usually screw the camera directly onto the mounting plate. Every time the camera is disassembled or maintained, the entire camera body needs to be rotated, which is very troublesome and easy to entangle the cables.

[0005] Therefore, there is an urgent need in this field for a mounting gimbal that has a simple structure but can provide high strength, high reliability locking, and is easy to assemble and disassemble. Utility Model Content

[0006] The technical problem to be solved by this utility model is to address the issues of unreliable friction locking, easy slippage, and inconvenient disassembly and assembly of existing pan-tilt units, and to provide an adjustable pan-tilt unit for cameras.

[0007] To solve the above-mentioned technical problems, the adjustable mounting head for cameras includes a base for fixing to a support surface, a mounting base for supporting the camera, and an adjustment bracket connecting the base and the mounting base; wherein the adjustment bracket is connected to the base and / or the mounting base by a gear locking mechanism; the gear locking mechanism includes a first gear and a second gear that face each other and can mesh with each other, and a locking knob passing through the axis of the first gear and the second gear; radial anti-slip teeth are provided on the opposing surfaces of the first gear and the second gear; a dovetail groove with a notch at one end is opened on the top of the mounting base, a quick-release slider for fixing the camera is provided in the dovetail groove, a push plate is provided at the bottom of the dovetail groove, and a locking bolt for pushing the push plate upward to tighten the quick-release slider (22) is installed at the bottom of the mounting base.

[0008] Furthermore, the adjustment bracket is a U-shaped bracket; the upper end of the base extends into the bottom opening of the U-shaped bracket and is connected to the U-shaped bracket through the gear locking mechanism to achieve horizontal angle adjustment and locking.

[0009] Furthermore, the bottom of the dovetail slide (21) is provided with a push plate (212), and the lower end of the mounting base extends into the top opening of the U-shaped bracket and is connected to the U-shaped bracket through another set of gear locking mechanisms to realize the angle adjustment and locking of the pitch direction.

[0010] Furthermore, the upper surface of the quick-release slider is provided with anti-slip rubber pads and standard 1 / 4-inch camera mounting screws.

[0011] This utility model discloses an adjustable mounting pan-tilt head for cameras, which overcomes the shortcomings of existing pan-tilt heads, such as unreliable friction locking, easy slippage, and inconvenient assembly and disassembly. By introducing a toothed disc meshing structure at the key rotating joint, it upgrades the traditional friction locking to mechanical meshing locking, greatly improving vibration resistance and load-bearing stability. At the same time, combined with a dovetail groove quick-release design, it enables quick assembly and disassembly of the camera and fine adjustment of the center of gravity while ensuring a stable connection, thus balancing professionalism and convenience.

Therefore, they should not be construed as limitations on this utility model.

[0016] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0017] Implementation method 1: such as Figures 1 to 4As shown, the adjustable pan-tilt head for a camera includes a base 1 for fixing to a support surface, a mounting base 2 for supporting the camera, and an adjustment bracket 3 connecting the base 1 and the mounting base 2; wherein the adjustment bracket 3 is connected to the base 1 and / or to the mounting base 2 via a geared locking mechanism 4; the geared locking mechanism 4 includes a first geared disc 41 and a second geared disc 42 that face each other and can mesh with each other, and a mechanism passing through the first geared disc 41 and the second geared disc 42. The locking knob 43 is located on the axis of the two-toothed disc 42; radial anti-slip teeth 44 are provided on the opposite surfaces of the first toothed disc 41 and the second toothed disc 42; a dovetail groove 21 with a notch 211 at one end is opened on the top of the mounting base 2, and a quick-release slider 22 for fixing the camera is provided in the dovetail groove 21; a push plate (12) is provided at the bottom of the dovetail groove 21, and a locking bolt 23 for pushing the push plate 212 upward to tighten the quick-release slider (22) is installed at the bottom of the mounting base 2. The base 1 is used for fixing A mounting hole can be pre-drilled in the center of the support surface such as a wall, ceiling, or tripod; the mounting base 2 is located at the top and is used to support the camera; the adjustment bracket 3 connects the base 1 and the mounting base 2, providing support and adjustment dimensions. A gear locking mechanism 4 is provided at the connection between the adjustment bracket 3 and the base 1 (responsible for horizontal rotation), and at the connection between the adjustment bracket 3 and the mounting base 2 (responsible for pitch rotation). Radial anti-slip teeth 44 are engraved on the contact surfaces of the two opposing gears. A locking mechanism with a handle is also included. The knob 43 passes through the axis of the two geared discs. When the angle needs to be adjusted, the user loosens the locking knob 43 counterclockwise, the first geared disc 41 and the second geared disc 42 separate, and the anti-slip teeth 44 disengage, allowing the bracket or mounting base to rotate freely. When the angle is adjusted to the correct position, the user tightens the locking knob 43 clockwise, and the two geared discs fit tightly together under pressure, with the anti-slip teeth 44 interlocking to form a rigid lock. At this point, no matter how much external force is applied (within the material's strength range), the pan-tilt unit cannot rotate, ensuring absolute stability of the monitoring angle.

[0018] Implementation method 2: such as Figure 1 , 4As shown, the adjustable mount 3 for the camera is a U-shaped bracket. The upper end of the base 1 extends into the bottom opening of the U-shaped bracket and is connected to the U-shaped bracket through the gear locking mechanism 4, achieving horizontal angle adjustment and locking. The lower end of the mounting base 2 extends into the top opening of the U-shaped bracket and is connected to the U-shaped bracket through another set of gear locking mechanisms 4, achieving pitch angle adjustment and locking. The adjustable bracket 3 is preferably a U-shaped bracket. At the horizontal joint, the first gear 41 is fixed to the upward-extending column of the base 1 (as a stationary end), and the second gear 42 is fixed to the bottom of the U-shaped adjustable bracket 3 (as a rotating end). At the pitch joint, the first gear 41 is fixed to the two side lugs at the top of the U-shaped adjustable bracket 3 (as a stationary end), and the second gear 42 is fixed to both sides of the mounting base 2 (as a rotating end). Through this double-joint gear locking design, the gimbal can be adjusted in both horizontal and pitch directions with high-strength locking.

[0019] Implementation method 3: such as Figure 2 , 3 As shown, the upper surface of the quick-release slider 22 of the adjustable pan-tilt head for cameras is provided with anti-slip rubber pads 221 and standard 1 / 4-inch camera mounting screws 222. To facilitate camera installation and removal, the top of the mounting base 2 is designed with a quick-release structure. The top of the mounting base 2 has an inverted trapezoidal dovetail groove 21, which is matched with the shape of the quick-release slider 22. The upper surface of the quick-release slider 22 is covered with anti-slip rubber pads 221 and equipped with standard 1 / 4-inch camera mounting screws 222 for first fixing the camera to the slider.

[0020] In use: Push the quick-release slider 22, with the camera mounted, into the dovetail groove 21 through the notch 211. Due to the structural characteristics of the dovetail groove, the slider will not fall upwards but can only slide back and forth along the groove. The user can move the slider back and forth according to the length of the camera to find the center of gravity balance point. After determining the position, tighten the locking bolt 23 located at the bottom of the mounting base 2. The end of the bolt pushes the push plate 212 upwards, thereby raising the bottom surface of the quick-release slider 22 and firmly pressing its two sides against the inner wall of the groove, thus locking the slider. With this design, when disassembling or assembling the camera, the user only needs to loosen the locking bolt 23 to remove the slider 22 along with the camera from the notch, without having to rotate the entire camera body, making the operation extremely convenient.

[0021] This adjustable camera mount incorporates a toothed engagement structure at key rotating joints, upgrading traditional friction locking to mechanical engagement locking, significantly improving vibration resistance and load-bearing stability. Simultaneously, combined with a dovetail quick-release design, it enables rapid camera assembly / disassembly and fine-tuning of the center of gravity while ensuring a secure connection, balancing professionalism and convenience. Specifically, (1) Mechanical engagement and secure locking: This utility model abandons the traditional friction locking method and innovatively adopts a toothed disc locking mechanism. By utilizing the mutual meshing of the radial anti-slip teeth on the end faces of the first and second toothed discs, a rigid mechanical engagement is formed. Once locked, relative rotation will never occur unless the teeth break. This greatly improves the vibration resistance and load-bearing stability of the pan-tilt unit and effectively prevents the camera from shifting at an angle due to gravity or wind.

[0022] (2) Quick assembly and disassembly with adjustable center of gravity: By setting a dovetail groove and quick-release slider on the top of the mounting base, users can simply loosen the locking bolts on the bottom surface to remove the slider along with the camera when assembling or disassembling the camera, without having to rotate the camera body, making the operation extremely convenient. At the same time, the long dovetail groove allows the slider to slide back and forth, making it convenient for users to fine-tune the center of gravity according to the weight distribution of the camera, further improving stability.

[0023] (3) Simple structure and easy operation: Due to the use of gear meshing principle, users do not need to tighten the knob to obtain a strong locking force, which extends the service life of the knob and improves the operating experience.
