Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary photographic equipment, and particularly relates to a camera base structure that can be turned 90 degrees. Background Art

[0002] The camera bases, cage mounts, L-shaped quick-release plates or long-shaped quick-release plates of traditional photographic equipment are all horizontally arranged, while the dovetail groove clamp seats of common video tripods are vertically arranged. This mismatch in direction causes users unable to directly install the dovetail groove plug plate onto the vertically arranged video tripod when using the video tripod, and must rely on additional adapter accessories to make a ninety-degree turn before use, which is inconvenient to operate and affects the shooting efficiency. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a camera base structure that can be turned 90 degrees. This camera base structure can be directly compatible with tripods in both horizontal and vertical layouts. The camera base can be directly placed on the vertically arranged video tripod for use, solving the technical problems described in the background art.

[0004] The present invention is achieved through the following technical solutions:

[0005] A camera base structure that can be turned 90 degrees, comprising a base and a dovetail groove plug plate. A groove is opened on the bottom surface of the base, and a connection hole is penetratively opened on the surface of the dovetail groove plug plate;

[0006] It further includes a rotating central axis. The rotating central axis passes through the connection hole and extends into the groove, and is fixedly connected to the base, connecting the dovetail groove plug plate to the base in a rotatable manner. A locking structure is provided on the rotating central axis for locking the dovetail groove plug plate after it rotates ninety degrees.

[0007] Further, the locking structure includes a limiting hole opened on the inner wall of the connection hole. A receiving cavity is opened on one side of the rotating central axis close to the base. A switch is movably inserted into the receiving cavity. When the switch is inserted into the limiting hole under the action of an external force, the rotation of the dovetail groove plug plate can be restricted.

[0008] Further, a sliding groove is provided on the bottom surface of the base. A sliding rod is fixedly connected to the dovetail groove plug 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 plug plate.

[0009] Further, a positioning hole is opened on the top surface of the dovetail groove plug plate. An installation hole is opened on the base. A spring is installed in the installation hole. A ball is fixedly provided at the outer end of the spring. In the natural state, the ball partially protrudes from the installation hole under the action of the spring.

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

[0011] Furthermore, a relief opening connected to the accommodating cavity is opened on the side of the rotating central axis away from the bottom plate, and the switch includes a limiting portion that slides with the accommodating cavity and a toggle portion that is integrally formed with the limiting portion, and the toggle portion extends outward through the relief opening.

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

[0013] Furthermore, the bottom plate is a quick-release plate.

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

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

[0016] The beneficial effects of the present invention are:

[0017] 1. The present invention uses a rotatable connection structure between the base plate and the dovetail slot insert to achieve direct installation of the horizontal quick-release plate and the vertical pan / tilt head without the need for an additional adapter. It is directly compatible with horizontal and vertical layouts, eliminates the direction mismatch problem of traditional solutions, and significantly improves device compatibility.

[0018] 2. The rotating central axis of the present invention is integrated between the base plate and the dovetail slot insert to form an integrated steerable structure. Compared with the traditional split adapter, it reduces the overall height and structural complexity, reduces the installation level and redundant components, and avoids the instability caused by the stacking of levels.

[0019] 3. The present invention uses the locking structure of the rotating central axis, so the user only needs to rotate the dovetail slot insert and lock it to complete the 90-degree direction switch, which can achieve fast switching and efficient locking, eliminating the tedious operation of repeatedly disassembling and assembling the adapter.

DETAILED DESCRIPTION

[0032] Typical embodiments that embody the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations are intended to be illustrative rather than limiting.

[0033] In the description of this application, the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These are 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, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0034] See also Figure 1 、 Figure 2 and Figure 4The present invention provides a technical solution: a camera cage, comprising a bottom plate 1 and a dovetail slot insert 2, wherein the bottom plate 1 is one of an L plate, a quick release plate, a cage or a straight bottom plate, such as Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 and Figure 11 As shown, the dovetail slot insert 2 is a plate structure that can be plugged into the dovetail slot. A circular groove 11 is provided on the bottom surface of the base plate 1, and a gasket 8 is installed in the groove 11. The dovetail slot insert 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 friction coefficient between the base plate 1 and the dovetail slot insert 2 while providing continuous pressing force.

[0035] See also Figures 5 to 7 The dovetail slot insert 2 has a connecting hole 21 extending through its surface. It also includes a rotating shaft 3 with a T-shaped cross-section. The rotating shaft 3 extends through the connecting hole 21 into the groove 11 and is fixedly connected to the base plate 1, rotatably connecting the dovetail slot insert 2 to the base plate 1. In this way, the base plate 1 and the dovetail slot insert 2 can rotate relative to each other. The rotating shaft 3 and the base plate 1 each have through-holes 14 extending vertically. A connecting screw 9 is installed in both through-holes 14. The connecting screw 9 is used to connect devices such as cameras.

[0036] See also Figure 4 、 Figure 5 and Figure 7 The rotating central axis 3 is provided with a locking structure 4, and the locking structure 4 includes a limiting hole 41 opened on the inner wall of the connecting hole 21. There are two limiting holes 41, and the arc angle between the two limiting holes 41 is ninety degrees. The rotating central axis 3 is provided with a accommodating cavity 42 on the side close to the base plate 1, and a switch 43 is movably inserted in the accommodating cavity 42. In this way, when the dovetail slot plug-in plate 2 rotates ninety degrees around the rotating central axis 3 relative to the base plate 1, the switch 43 can be manually toggled and inserted into the limiting hole 41 to keep the base plate 1 and the dovetail slot plug-in plate 2 in a ninety-degree cross arrangement. At this time, the dovetail slot plug-in plate 2 can be directly inserted into the photographic gimbal for use without the auxiliary installation through an adapter.

[0037] See also Figure 3 、 Figure 4 、 Figure 6 and Figure 8The side of the rotating central axis 3 away from the bottom plate 1 is provided with an avoidance opening 31 connected to the accommodating cavity 42. The switch 43 includes a limiting portion 431 that slides with the accommodating cavity 42 and a toggle portion 432 that is integrally formed with the limiting portion 431. The toggle portion 432 extends outward through the avoidance opening 31. When the dovetail slot plug-in plate 2 is rotated ninety degrees relative to the bottom plate 1, the operation can be performed directly at the bottom of the dovetail slot plug-in plate 2. The limiting portion 431 is toggled by the toggle portion 432 to insert into the limiting hole 41, which makes it more convenient to limit the relative rotation of the dovetail slot plug-in plate 2 and the bottom plate 1.

[0038] See also Figure 5 and Figure 6 The bottom surface of the base plate 1 is provided with a slide groove 12, and a slide rod 5 is fixedly connected to the dovetail groove plug-in plate 2. The free end of the slide rod 5 extends into the slide groove 12 and cooperates with the slide groove 12 to limit the rotation angle of the dovetail groove plug-in plate 2. The slide rod 5 cooperates with the slide groove 12 to limit the direction in which the dovetail groove plug-in plate 2 is rotated out or stored, and the angular range in which the dovetail groove plug-in plate 2 can be rotated can be limited (exactly ninety degrees), so that the dovetail groove plug-in plate 2 can be quickly adjusted to the required usage state.

[0039] See also Figure 5 and Figure 6 The top surface of the dovetail slot insert 2 is provided with a plurality of positioning holes 22, and the bottom plate 1 is provided with a mounting hole 13. A spring 6 is installed in the mounting hole 13, and a ball 7 is fixed to the outward end of the spring 6. In a natural state, the ball 7 is half extended out of the mounting hole 13 under the action of the spring 6. When the dovetail slot insert 2 rotates, the ball 7 is squeezed by the spring 6. When the dovetail slot insert 2 rotates 90 degrees, the ball 7 is pressed into the positioning hole 22 under the action of the spring 6, and a clear "click" mechanical sound and a mechanical feel are produced, so that the successful operation can be perceived without visual confirmation (similar to the mode dial of a high-end camera). In addition, when the ball 7 is embedded in the positioning hole 22 under the pressure of the spring 6, the rotation angle is physically locked (such as 90 degrees), avoiding deviation caused by misoperation.

[0040] Finally, it should be noted that the above invention is only a preferred embodiment of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
