Description

Technical Field

[0001] This utility model relates to the field of auxiliary photography equipment technology, specifically to a camera base plate structure that can rotate 90 degrees. Background Technology

[0002] Traditional photographic equipment features horizontally laid-out camera base plates, cages, L-shaped quick-release plates, or long quick-release plates, while common video gimbals have vertically laid-out dovetail mounts. This directional mismatch means that users cannot directly install the dovetail mount onto a vertically laid-out video gimbal; they must rely on additional adapters to rotate it 90 degrees before it can be used, which is inconvenient and affects shooting efficiency. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a camera base plate structure that can rotate 90 degrees. This camera base plate structure is directly compatible with both horizontal and vertical gimbals. The camera base plate can be directly placed on a vertically arranged video gimbal for use, thus solving the technical problems described in the background art.

[0004] This utility model is achieved through the following technical solution:

[0005] A camera base plate structure that can rotate 90 degrees includes a base plate and a dovetail groove plate. The bottom surface of the base plate has a groove, and the surface of the dovetail groove plate has a through-hole.

[0006] It also includes a rotating central shaft, which extends through the connecting hole into the groove and is fixedly connected to the base plate, thereby rotatably connecting the dovetail groove plate to the base plate. The rotating central shaft is provided with a locking structure for locking the dovetail groove plate after it has rotated 90 degrees.

[0007] Furthermore, the locking structure includes a limiting hole opened on the inner wall of the connecting hole, and a receiving cavity is opened on the side of the rotating central shaft near the bottom plate. A switch is movably inserted into the receiving cavity. When the switch is inserted into the limiting hole under the action of external force, it can restrict the rotation of the dovetail groove plate.

[0008] Furthermore, the bottom surface of the base plate is provided with a sliding groove, and a sliding rod is fixedly connected to the dovetail groove plate. The free end of the sliding rod extends into the sliding groove and cooperates with the sliding groove to limit the rotation angle of the dovetail groove plate.

[0009] Furthermore, the top surface of the dovetail groove insert plate is provided with a positioning hole, the bottom plate is provided with a mounting hole, a spring is installed in the mounting hole, and a ball is fixed at the outward end of the spring. In its natural state, the ball protrudes halfway out of the mounting hole under the action of the spring.

[0010] Furthermore, a gasket is installed in the groove, and the dovetail groove plate has a protrusion on the side facing the base plate. The protrusion extends into the groove and contacts the surface of the gasket.

[0011] Furthermore, the rotating central axis has a clearance opening on the side away from the base plate that communicates with the receiving cavity. The switch includes a limiting part that slides with the receiving cavity and a toggle part that is integrally formed with the limiting part. The toggle part extends outward through the clearance opening.

[0012] Furthermore, the base plate is an L-shaped plate.

[0013] Furthermore, the base plate is a quick-installation plate.

[0014] Furthermore, the base plate is a rabbit cage.

[0015] Furthermore, the base plate is a straight base plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through the rotatable connection structure between the base plate and the dovetail groove insert plate, enables the direct installation of the horizontal quick-release plate and the vertical gimbal without the need for an additional adapter. It is directly compatible with both horizontal and vertical layouts, eliminates the directional mismatch problem of traditional solutions, and significantly improves equipment compatibility.

[0018] 2. The rotating central shaft of this utility model is integrated between the base plate and the dovetail groove insert plate to form an integrated steerable structure. Compared with the traditional split adapter, it reduces the overall height and structural complexity, reduces the number of installation layers and redundant parts, and avoids instability caused by the superposition of layers.

[0019] 3. With the locking structure of the rotating central shaft, the user only needs to rotate the dovetail slot plate and lock it to complete the 90-degree direction switching, which is quick and efficient, saving the tedious operation of repeatedly disassembling and assembling the adapter.

Detailed Implementation

[0032] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0033] In the description of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: a camera rabbit cage, including a base plate 1 and a dovetail groove insert plate 2, wherein the base plate 1 is one of an L-plate, a quick-release plate, a rabbit cage, or a straight base plate, etc. Figure 1 , Figure 2 , Figure 9 , Figure 10 and Figure 11 As shown, the dovetail groove insert plate 2 is a plate structure that can be inserted and mated with the dovetail groove. The bottom surface of the base plate 1 has a circular groove 11, and a gasket 8 is installed in the groove 11. The dovetail groove insert plate 2 has a protrusion 23 on the side facing the base plate 1. The protrusion 23 extends into the groove 11 and contacts the surface of the gasket 8. The gasket 8 is made of elastic material and is used as an isolation layer to reduce the coefficient of friction between the base plate 1 and the dovetail groove insert plate 2, while providing continuous clamping force.

[0035] Please see Figures 5 to 7 The dovetail groove insert 2 has a through-hole 21 on its surface and also includes a rotating central shaft 3. The rotating central shaft 3 has a T-shaped cross-section and extends through the through-hole 21 into the groove 11, where it is fixedly connected to the base plate 1. This allows the dovetail groove insert 2 to be rotatably integrated with the base plate 1, enabling relative rotation between the base plate 1 and the dovetail groove insert 2. Both the rotating central shaft 3 and the base plate 1 have through holes 14 extending vertically. A connecting screw 9 passes through both through holes 14 for connecting devices such as cameras.

[0036] Please see Figure 4 , Figure 5 and Figure 7 The rotating central shaft 3 is provided with a locking structure 4, which includes two limiting holes 41 on the inner wall of the connecting hole 21. The arc angle between the two limiting holes 41 is ninety degrees. The rotating central shaft 3 has a receiving cavity 42 on the side near the base plate 1. A switch 43 is movably inserted into the receiving cavity 42. When the dovetail groove plate 2 rotates ninety degrees relative to the base plate 1 around the rotating central shaft 3, the base plate 1 and the dovetail groove plate 2 can be kept in a ninety-degree cross arrangement by manually moving the switch 43 into the limiting hole 41. At this time, the dovetail groove plate 2 can be directly inserted into the camera tripod without the need for an adapter.

[0037] Please see Figure 3 , Figure 4 , Figure 6 and Figure 8 The rotating central shaft 3 has a clearance opening 31 on the side away from the base plate 1 that communicates with the receiving cavity 42. The switch 43 includes a limiting part 431 that slides with the receiving cavity 42 and a toggle part 432 integrally formed with the limiting part 431. The toggle part 432 extends outward through the clearance opening 31. When the dovetail groove insert 2 rotates 90 degrees relative to the base plate 1, it can be operated directly at the bottom of the dovetail groove insert 2. The limiting part 431 is inserted into the limiting hole 41 by the toggle part 432, which restricts the relative rotation of the dovetail groove insert 2 and the base plate 1, making the operation more convenient.

[0038] Please see Figure 5 and Figure 6 The bottom surface of the base plate 1 is provided with a sliding groove 12, and a sliding rod 5 is fixedly connected to the dovetail slot plate 2. The free end of the sliding rod 5 extends into the sliding groove 12 and cooperates with the sliding groove 12 to limit the rotation angle of the dovetail slot plate 2. By cooperating with the sliding groove 12, the direction in which the dovetail slot plate 2 rotates out or is stored can be limited, and the range of rotation angles of the dovetail slot plate 2 can be limited (exactly ninety degrees) so that the dovetail slot plate 2 can be quickly adjusted to the required usage state.

[0039] Please see Figure 5 and Figure 6 The dovetail-groove insert plate 2 has multiple positioning holes 22 on its top surface, and the base plate 1 has mounting holes 13. A spring 6 is installed in the mounting holes 13, and a ball bearing 7 is fixed to the outward end of the spring 6. In its natural state, the ball bearing 7 protrudes halfway out of the mounting hole 13 under the action of the spring 6. When the dovetail-groove insert plate 2 rotates, it squeezes the ball bearing 7. When the dovetail-groove insert plate 2 rotates 90 degrees, the ball bearing 7 is pressed into the positioning hole 22 under the action of the spring 6, producing a distinct "click" mechanical sound and a mechanical feel, allowing the user to perceive successful operation without visual confirmation (similar to the mode dial of a high-end camera). In addition, when the ball bearing 7 is embedded in the positioning hole 22 under the pressure of the spring 6, it achieves physical locking of the rotation angle (e.g., 90 degrees), preventing deviation caused by accidental operation.

[0040] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
