TECHNICAL FIELD

[0001] The utility model relates to photographic equipment field especially, it is a cloud platform structure for being connected with tripod and camera. BACKGROUND

[0002] In the existing photographic tripod and camera connection mode, usually adopt traditional screw connection mode, namely 1 / 4 screw of camera bottom is screwed into the corresponding interface of cloud platform, to realize the fixation of both. However, this traditional connection mode has some shortcomings:

[0003] 1. Complicated operation: when installing and dismounting the camera, need to use tools (such as wrench etc.) or manually rotate screw several times to complete the fixed or loosening operation, this in the case where the camera needs to be frequently replaced or the shooting angle is adjusted, will waste a lot of time and energy, reduces the shooting efficiency.

[0004] 2. Not firm: in the complex environment such as outdoor shooting, due to the influence of factors such as vibration, wind force, insufficient screw torque, ordinary screw connection mode may cause the camera and the cloud platform to appear loose or slip, thereby affecting the shooting quality, and even possibly damaging the equipment.

[0018] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below by combining with the drawings and examples. It should be understood that the structure diagram and specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0019] Example one

[0020] As Figures 1-3 Indicated, the utility model provides an embodiment of torque lock holder, including holder main body 1, pulley 2, screw interface 3 and threading hole 4. The threaded hole 4 of the lower part of the holder main body 1 is the interface connected with tripod, and the upper part is provided with the screw interface 3 matched with the 1 / 4 threaded hole of the camera bottom, which is connected with the pulley 2 through the center shaft.

[0021] The pulley 2 is located at the middle part of the holder main body 1, and the surface has anti-skid lines, facilitating manual rotation operation. The pulley 2 and the screw interface 3 are fixedly connected on the same intermediate shaft, the rotation of the pulley 2 drives the rotation of the screw interface 3 through the intermediate shaft, the screw interface 3 is connected with the 1 / 4 screw in the threaded hole of the camera base, so that the rotation of the pulley 2 can drive the rotation of the screw interface 3, realizing the self-tapping or spinning action of the screw. In the embodiment, the diameter size of the pulley 2 is much larger than the diameter size of the center shaft, according to the angular momentum conservation law, since the force arm of the pulley 2 to the center shaft is longer than the force arm of the screw interface 3, the smaller force acting on the pulley 2 is transmitted to the larger force of the screw interface 3, while ensuring that the rotation speed of the screw interface 3 is moderate.

[0022] The pulley 3 and screw interface 3 are both installed inside the pan / tilt head body 1. The pan / tilt head body 1 adopts an integrated hollow design to ensure the high strength and aesthetics of the overall structure. At the same time, the outer circumference of the pulley 3 needs to be exposed from the outside of the pan / tilt head body 1 to facilitate manual rotation.

[0023] The following is a further explanation of the working principle of the present invention with reference to the accompanying drawings:

[0024] To secure the camera to the gimbal, the user simply aligns the 1 / 4 screw hole on the bottom of the camera with the screw interface on the gimbal platform. Then, manually rotate the pulley, which drives the screw interface via its central axis. The high torque transmitted by the pulley to the screw interface allows the screw to quickly self-tap into the screw hole on the bottom of the camera, achieving a tight connection. While rotating the pulley, the user can control the torque by feel and observing the camera's securement, ensuring a secure hold.

[0025] To remove the camera, simply rotate the pulley in the opposite direction, unscrewing the screw connector from the threaded hole on the bottom of the camera. This tool-free operation is quick and easy, significantly improving the efficiency of mounting and dismounting photographic equipment.

[0026] Example 2

[0027] like Figure 4 As shown, the present invention provides another embodiment of a torque lock gimbal. The pulley 2 has an internal gear 6, and the screw interface 3 is integral with the central shaft. The central shaft is mounted with an external gear 5. The internal gear 6 of the pulley 2 meshes with the external gear 5 of the central shaft. When the pulley 2 is rotated, the rotational torque of the pulley 2 is transmitted to the central shaft through the intermeshing gears, thereby causing the bolt interface 3 integral with the central shaft to rotate. The screw interface 3 then self-taps into the screw hole on the bottom of the camera, thereby connecting the gimbal to the camera.

[0028] The utility model has the following beneficial effects:

[0029] 1. Quick fix: Compared with the traditional threaded connection method, the torque lock gimbal of this utility model can quickly fix the camera on the gimbal through the design of a large torque pulley, saving installation and disassembly time and improving shooting efficiency. It is especially suitable for occasions that require frequent replacement of shooting equipment or adjustment of shooting angles.

[0030] 2. Strong and Stable: The high-torque design and self-tapping connection method make the connection between the camera and the gimbal more secure, which can effectively resist adverse factors such as vibration and wind during outdoor shooting, prevent the device from loosening or slipping, ensure shooting stability and image quality, and reduce the production of failed shots or blurred photos caused by device shaking.

[0031] 3. Easy to operate: No additional tools are required; users can fix and remove the camera simply by turning the pulley. The operation is simple and intuitive, making it easy for even non-professionals to use, lowering the barrier to entry and improving the user experience.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
