[0065] The present application is described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0066] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0067] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0068] In the prior art, the cold shoe with a rotation function includes a cold shoe seat and a base plate. The cold shoe seat needs to be connected to the camera through the base plate so that the cold shoe seat can rotate relative to the camera and the base plate, which increases the manufacturing cost of the cold shoe.

[0069] To solve the above problems, the present application provides a rotating cold shoe. Figure 1 As shown, it is a schematic diagram of the structure of a rotating cold shoe provided by an embodiment of the present application. The rotating cold shoe comprises a first cold shoe seat 1, a second cold shoe seat 2 and a fixing member 3, wherein:

[0070] The first cold shoe mount 1 is provided with a cold shoe slot 11 for connecting photography auxiliary accessories such as a microphone and a fill light. The cold shoe slot 11 includes a baffle 111, an anti-dropping block 112, an adjusting block 113 and a spring 114. The second cold shoe mount 2 is provided with a mounting hole adapted to the anti-dropping block 112. The anti-dropping block 112 is provided with a connecting hole connected to the adjusting block 113. The spring 114 is arranged in the mounting hole. The bottom of the anti-dropping block 112 abuts against the spring 114. The second cold shoe mount 2 is also provided with an annular hole 22 that passes through the mounting hole. The adjusting block 113 passes through the annular hole 22 and is fixedly connected to the anti-dropping block 112, such as a threaded connection.

[0071] The adjustment block 113 can move up and down in the annular hole 22. When the rotating cold shoe is connected to the cold shoe piece of the photography auxiliary accessory, the adjustment block 113 can be pressed downward, and the spring 114 contracts, and the anti-drop block 112 descends; when the cold shoe piece abuts against the baffle 111 of the cold shoe slot 11, the anti-drop block 112 is pushed upward under the elastic force of the spring 114, and the anti-drop block 112 plays a role of limiting and hindering in the installation direction, thereby cooperating with the limiting effect of the baffle 111 to prevent the rotating cold shoe from falling off, and the connection method is simple. Similarly, when the cold shoe piece needs to slide out of the cold shoe slot 11, it is only necessary to press the adjustment block 113 downward to release the restriction of the anti-drop block 112 on the cold shoe piece. In some implementation schemes, in order to facilitate installation and connection, an inclined surface is provided on the head of the anti-drop block 112. When the cold shoe is connected with the cold shoe piece, it is not necessary to press the adjustment block 113. The rotating cold shoe can be directly installed into the cold shoe piece by utilizing the inclined surface provided at the head of the anti-slip block 112, which is simple and convenient.

[0072] The second cold shoe mount 2 is fixed to the first cold shoe mount 1, for example, by a threaded connection, and of course other connection and fixing methods can also be used. A first cavity 10 is formed between the first cold shoe mount 1 and the second cold shoe mount 2, one end of the fixing member 3 is accommodated in the first cavity 10, and the other end extends out of the first cavity 10, and the fixing member 3 can rotate relative to the first cold shoe mount 1 and the second cold shoe mount 2. The rotating cold shoe provided in the present application forms a first cavity 10 for accommodating the fixing member 3 by utilizing the cooperation of the first cold shoe mount 1 and the second cold shoe mount 2, so that the fixing member 3 can rotate relative to the first cold shoe mount 1 and the second cold shoe mount 2, thereby realizing that the cold shoe mount can rotate relative to the camera without the need for a bottom plate, thereby reducing the manufacturing cost of the cold shoe.

[0073] like Figure 2 and Figure 3 As shown, in some embodiments, the rotating cold shoe further includes a transition component 4, at least part of which is accommodated in the first cavity 10, and the fixing member 3 is relatively fixed to the transition component 4 and the two can rotate relative to the first cold shoe seat 1 and the second cold shoe seat 2; or the fixing member 3 can rotate relative to the transition component 4, the first cold shoe seat 1 and the second cold shoe seat 2. Since the fixing member 3 has various forms (see above), the present application can realize the conversion of the standard fixing member 3 by using the transition component 4, so that the fixing members 3 of different structural forms can cooperate with the first cold shoe seat 1 and the second cold shoe seat 2 of the same structure to rotate, which greatly improves the adaptability and convenience of the product; at the same time, the fixing member 3 can also be facilitated to rotate relative to the first cold shoe seat 1 and the second cold shoe seat 2 with the help of the transition component 4. Moreover, the fixing member 3 can have two rotation modes: 1) the fixing member 3 and the transition component 4 are relatively fixed and the two can rotate relative to the first cold shoe seat 1 and the second cold shoe seat 2; 2) the fixing member 3 can rotate relative to the transition component 4, the first cold shoe seat 1 and the second cold shoe seat 2.

[0074] In some embodiments, the transition assembly 4 includes a cover plate 41 and a shaft seat 42, the shaft seat 42 is fixedly connected to the cover plate 41, and a second cavity 20 is formed therebetween, the fixing member 3 and the shaft seat 42 are fixedly or rotatably disposed in the second cavity 20, and the cover plate 41 and the shaft seat 42 are accommodated in the first cavity 10. For example, Figure 1 and Figure 4 The fixing member 3 in the rotating cold shoe is rotatably disposed in the second cavity 20, so that the fixing member 3 can rotate relative to the transition assembly 4, the first cold shoe seat 1 and the second cold shoe seat 2; for another example, Figure 5 , Figure 6 and Figure 7 The fixing member 3 in the rotating cold shoe is fixed to the shaft seat 42, so that the fixing member 3 and the transition assembly 4 are relatively fixed and both can rotate relative to the first cold shoe seat 1 and the second cold shoe seat 2. By arranging the transition assembly 4 as a split assembly structure, it is convenient to install the fixing member 3 or to cooperate with the fixing member 3, and when the fixing member 3 is rotatably arranged in the second cavity 20, it is possible to avoid contact between the fixing member 3 and the second cold shoe seat 2, thereby further increasing the service life of the rotating cold shoe.

[0075] In some embodiments, the second cold shoe mount 2 is provided with a fixing portion 21, and the cover plate 41 and the shaft seat 42 cooperate with the fixing portion 21 to be accommodated in the first cavity 10. From the above analysis, it can be known that the transition assembly 4 can be fixed or rotated relative to the second cold shoe mount 2. When it is the former, the fixing portion 21 can be an internal thread, and one of the cover plate 41 or the shaft seat 42 has an external thread to cooperate with the fixing portion 21, and then can be fixed inside the second cold shoe mount 2; of course, the fixing portion 21 can also be other structures that can be fixed to the transition assembly 4, such as a snap-fit ​​structure, an interference fit structure, etc., which are not specifically limited here. When the transition assembly 4 rotates relative to the second cold shoe mount 2, the fixing portion 21 can be a protrusion extending from the inner wall of the second cold shoe mount 2 into the first cavity 10 to support the cover plate 41 or the cover plate 41 and the shaft seat 42.

[0076] In some embodiments, the fixing portion 21 is an annular protrusion, the cover plate 41 is disposed on one side of the annular protrusion, and at least a portion of the shaft seat 42 is disposed on the other side of the annular protrusion. In this configuration, the fixing portion 21 can be located between the cover plate 41 and the shaft seat 42 by fixing the cover plate 41 and the shaft seat 42. For example, when the pressure generated between the cover plate 41, the shaft seat 42 and the annular protrusion is relatively large, it can be considered that the transition assembly 4 can be fixed relative to the second cold shoe seat 2; on the contrary, if the pressure generated between the cover plate 41, the shaft seat 42 and the annular protrusion is relatively small, it can be considered that the transition assembly 4 can rotate relative to the second cold shoe seat 2. Therefore, by disposing the cover plate 41 on one side of the annular protrusion and at least a portion of the shaft seat 42 on the other side of the annular protrusion, it can be achieved that the transition assembly 4 can rotate relative to the second cold shoe seat 2.

[0077] In some embodiments, the shaft seat 42 includes a first shaft seat 421 and a second shaft seat 422. The first shaft seat 421 is formed on the second shaft seat 422. The first shaft seat 421 is inserted into the annular protrusion and is fixedly connected to the cover plate 41. The second shaft seat 422 is arranged on the other side of the annular protrusion. In other words, the outer diameter of the first shaft seat 421 is smaller than the outer diameter of the second shaft seat 422, so as to facilitate avoiding the annular protrusion.

[0078] In some embodiments, a first gasket 51 is provided between the cover plate 41 and the annular protrusion and between the second shaft seat 422 and the annular protrusion. In some implementation schemes, the first cold shoe seat 1 and the second cold shoe seat 2 can be made of aluminum alloy, and the fixing member 3 and the transition assembly 4 can be made of metal. When the transition assembly 4 rotates relative to the second cold shoe seat 2, a first gasket 51 is provided between the cover plate 41 and the annular protrusion and between the second shaft seat 422 and the annular protrusion to prevent the metal transition assembly 4 from scratching the aluminum alloy second cold shoe seat 2. At the same time, the first gasket 51 can also play a role in damping the transition assembly 4 when it rotates, so as to make the rotation of the transition assembly 4 more stable. In some implementation schemes, the first gasket 51 can be made of plastic material, such as nylon, PVC, PET and other materials.

[0079] In some embodiments, the second shaft seat 422 is provided with a second gasket 52 along the direction in which the fixing member 3 extends out of the first cavity 10. When the rotating cold shoe is mounted on the camera frame, and the transition assembly 4 can rotate relative to the second cold shoe seat 2, the second shaft seat 422 is provided with a second gasket 52 along the direction in which the fixing member 3 extends out of the first cavity 10 to prevent the second shaft seat 422 from scratching the camera frame. In some implementation schemes, the second gasket 52 can be fixed to the second shaft seat 422 by gluing, and the second gasket 52 can be made of silicone material.

[0080] In some embodiments, the top surface of the cover plate 41 does not exceed the top surface of the second cold shoe seat 2, so that the cover plate 41 can avoid interference with the bottom surface of the first cold shoe seat 1. The cover plate 41 is connected to the shaft seat 42 through a fastener 43. The cover plate 41 is provided with a tapered hole 411. The head of the fastener 43 is tapered, so that the thickness of the cover plate 41 can be thinner to further reduce the manufacturing cost. At the same time, the tapered hole 411 can also be squeezed by the fastener 43 with a tapered head to fasten the cover plate 41 to the shaft seat 42. In some implementation schemes, the fastener 43 can be a screw with a tapered head. The top surface of the fastener 43 does not exceed the top surface of the cover plate 41, so that the fastener 43 can avoid interference with the bottom surface of the first cold shoe seat 1.

[0081] In some embodiments, the cover plate 41 is further provided with a positioning hole 412, and the shaft seat 42 is further provided with a positioning column 421a, which can be inserted into the positioning hole 412, so as to achieve the positioning of the cover plate 41 and the shaft seat 42, so that the fastener 43 can correctly and quickly fasten the cover plate 41 and the shaft seat 42.

[0082] Please continue reading Figures 1 to 3 The first cold shoe seat 1 is also provided with a first through hole 115, and the cover plate 41 is also provided with a second through hole 413. The first through hole 115, the second through hole 413 and the second cavity 20 are connected to expose the head of the fixing member 3, so as to facilitate the fastening of the fixing member 3.

[0083] In some implementations, the fixing member 3 may be fixed to the camera frame directly or through other adapters. The specific structure of the fixing member 3 may be adjusted according to actual conditions. In some implementations, the fixing member 3 may include a screw 31 (see Figure 1 ), two screws 31 (see Figure 4 ), a screw 31 and two positioning pins 32 (see Figure 5 ), the slideway locking member 33 (see Figure 6 ) or cold shoe locking member 34 (see Figure 7 ), the specific structure of the fixing member 3 is not specifically limited in this application, as long as the fixing member 3 can be fixedly connected to the camera frame. Figure 7 For the rotating cold shoe shown, the fixing member 3 further includes an adjusting ring 35, by screwing the adjusting ring 35, the gap between the cold shoe locking member 34 and the cold shoe piece on the external device can be realized to tighten or loosen the cold shoe locking member 34 and the external device cold shoe piece.

[0084] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
