[0037] The present invention provides a photographic kit. In a first embodiment, referring to Figures 1 to 7The photographic kit includes a first photographic device 6 and a first external component for clamping and fixing the first photographic device 6. The first photographic device 6 includes a first frame 61. The first external component can be a clamping component. The clamping component includes two clamping bodies 1, a mounting seat 2 and a first locking component. The two clamping bodies 1 are rotatably arranged on opposite sides of the mounting seat 2, and the heads of the two clamping bodies 1 extend out of the front end of the mounting seat 2 to be clamped and fixed on the edges of both sides of the first frame 61. The two outer surfaces of the clamping body 1 near the rear end are convexly provided with a connecting portion 12 extending away from the clamping body. The connecting portion One end of 12 away from the clamping body 1 is connected with a pressing portion 13, and the pressing portion 13 extends toward the rear end of the mounting seat 2, so that a pressing space is formed between the pressing portion 13 and the mounting seat 2. The clamping body 1 is rotatably connected to the mounting seat 2 through a connecting shaft 14. A second spring 15 is provided between the two clamping bodies 1, and the second spring 15 drives the two clamping bodies 1 to clamp and fix the first frame 61. The clamping body 1 applies the lever principle, and the pressing portion 13 extends the force arm to save effort. The pressing space increases the opening angle of the clamping body 1, and the use of the connecting portion 12 reduces the volume of the mounting seat 2.

[0038] The first locking assembly can be telescopically mounted on the mounting seat 2 , and the limiting portion of the first locking assembly can extend out of the front end of the mounting seat, and the limiting portion is used to be inserted into the positioning hole 62 correspondingly provided in the first frame 61 .

[0039] In this embodiment, the heads of the two clamping bodies 1 and the front end of the mounting seat 2 form a clamping space for clamping the first frame 61. The limiting portion of the first locking assembly can extend out of the front end of the mounting seat 2 for accurate positioning. A pressing space is formed between the two pressing portions 13 and the two sides of the mounting seat 2. During assembly, when the user presses the two pressing portions 13 at the same time, the two clamping bodies 1 rotate relative to the mounting seat 2, so that the distance between the heads of the two clamping bodies 1 gradually increases, and the second spring 15 is further compressed. In the process of the first frame 61 extending into the clamping space, the two limiting portions are respectively inserted into the two positioning holes 62, releasing the two clamping bodies 1. Afterwards, the second spring 15 makes the heads of the two clamping bodies 1 clamped and fixed on the two side edges of the first frame 61 respectively, and the first locking assembly presses against the first photographic equipment 6, so that there is a bearing capacity between the mounting seat 2 and the first photographic equipment 6, thereby realizing that the two clamping bodies 1 stably clamp the first photographic equipment 6, saving effort in operation and improving user experience; when disassembling, the two clamping bodies 1 are pressed again to rotate them relative to the mounting seat 2, so that the heads of the two clamping bodies 1 release the first frame 61, the first photographic equipment 6 is separated from the mounting seat 2, and the first locking assembly returns to its original position, which is simple to operate and improves the user's shooting experience.

[0040] Among them, the first locking assembly can be located between the two clamping bodies 1, so that the overall structure is compact and occupies a small space; the pressing part 13 and the clamping body 1 can be arranged in parallel, and the pressing part 13 and the clamping body 1 can both be in the form of sheets, and the head of the clamping body 1 is used to clamp and fix the first frame 61 of the first photographic equipment 6, such as the inner side of the head of the clamping body 1 can have a friction part 131 for clamping the first photographic equipment 6, so that the head of the clamping body 1 and the first photographic equipment 6 are plug-fitted or snap-fitted. The clamping body 1 can be rotatably connected to the mounting seat 2 through a torsion spring and a connecting shaft 14, and the middle area of ​​the clamping body 1 can have a through hole for rotatably connecting to the connecting shaft 14, such as a clamping body 1 is connected to the mounting seat 2 through a torsion spring and a connecting shaft 14, and the two clamping bodies 1 can also be rotatably connected through a torsion spring, and of course, a compression spring can also be provided between the two clamping bodies 1, and the compression spring can be sleeved on the limit rod. The front end of the mounting seat 2 can be adapted to the shape of the first frame 61 of the first photographic device 6. For example, the outer surface of the first frame 61 of the first photographic device 6 opposite to the front end of the mounting seat 2 can be a plane, and the front end surface of the mounting seat 2 can be a plane. Figure 7 As shown, the mounting seat 2 can form corresponding mounting positions of slots and holes for mounting various components. The mounting seat 2 has a mounting space 23 extending therethrough on the left and right sides, and the two clamping bodies 1 cover the two sides of the opening of the mounting space 23 respectively, for mounting a torsion spring, a compression spring or a limit rod, etc. The front end of the mounting seat 2 has a mounting hole 22 extending therethrough, and the mounting hole 22 is connected to the mounting space 23. The top holding member 31 is slidably accommodated in the mounting hole 22, and the cylinder 311 extends out of the mounting hole 22.

[0041] In order to save effort when pressing the pressing part 13 and to increase the pressing space, the free end of the pressing part 13 extends out of the rear end of the mounting seat 2, and the thickness of the mounting seat 2 between the two clamping bodies 1 is reduced. In order to facilitate pressing, the friction parts 131 can form a pattern, and the friction parts 131 can also be convex or dot-shaped, and of course can also be other shapes, such as tire pattern.

[0042] The mounting seat 2 is also connected to the second photographic equipment 7, so as to realize the fixed connection between the first photographic equipment 6 and the second photographic equipment 7. Preferably, the rear end of the mounting seat 2 is provided with an external connection portion 21, and the external connection portion 21 is used to connect the second photographic equipment 7. The maximum cross-sectional area of ​​the connection portion between the external connection portion 21 and the mounting seat 2 is smaller than the surface area of ​​the rear end of the mounting seat 2, and the external connection portion 21 is located between the free ends of the two pressing portions 13 to form a pressing space with the pressing portions 13. The mounting seat 2 and the external connection portion 21 can be provided integrally or separately.

[0043] like Figure 3 and Figure 5As shown, further, the first locking assembly includes at least one top holding member, and one end of the top holding member 31 is provided with a limiting portion, and the limiting portion includes a cylinder 311, and the cross-sectional area of ​​the cylinder 311 is smaller than the cross-sectional area of ​​the connecting portion of the top holding member 31 and the cylinder 311, and the width dimension of the end of the cylinder 311 is gradually reduced to facilitate rapid and accurate insertion into the positioning hole 62, such as the free end of the cylinder 311 is a cone. The positioning hole 62 is provided with an internal thread 621, and when the first frame 61 is not connected to the first external component, the positioning hole 62 can be connected to other photographic components or accessories to increase the use function of the first photographic equipment 6.

[0044] Among them, the first photographic equipment 6 and the second photographic equipment 7 can both be accessories for assisting electronic equipment in shooting. The first photographic equipment 6 can be a camera, a mobile phone, a stabilizer protection frame (expansion frame), an L-plate, an adapter plate, etc., and the second photographic equipment 7 can be a side handle, an upper handle, a microphone stand, etc. If the first photographic equipment 6 is a cage (mobile phone, stabilizer, camera and other electronic devices), the cage is also called a rabbit cage, a protection frame, an expansion frame, etc. The cage can be half-enclosed or fully enclosed, such as the cage includes four frames connected in sequence, each frame can include one or more first frames, such as the left and right frames are both provided with a first frame 61. In order to make the connection more stable, a limiting groove can be formed at the opening of the positioning hole 62, and the connecting part of the top holding member 31 and the limiting part can be limited in the limiting groove.

[0045] Preferably, the mounting seat 2 further includes at least one elastic member 32, which is installed in the mounting seat 2. An elastic member 32 is used to drive a top holding member 31 so that the limiting portion protrudes from the front end of the mounting seat 2. The elastic member 32 can be a first spring, which is compressed or stretched to enable the limiting portion of the top holding member extending from the front end of the mounting seat 2 to move along the front-to-back direction of the mounting seat 2. One first spring or more than one first spring can simultaneously drive two top holding members through the plate body to ensure synchronization. The first spring is installed in the mounting seat 2, and one end of the top holding member 31 is connected to the first spring, so that the limiting portion can extend from the front end of the mounting seat 2.

[0046] In this embodiment, the top holding member 31 can be any of a cylindrical shape, a rod, a block, and a ball. When the first frame 61 of the first photographic equipment 6 extends into the clamping space, the limiting portion of the top holding member 31 extends out of the front end of the mounting seat 2, and the two sides of the first frame 61 of the first photographic equipment 6 push the cylinder 311 of the top holding member 31 to move toward the mounting seat 2. After releasing the two clamping bodies 1, the heads of the two clamping bodies 1 are clamped and fixed on both sides of the first frame 61 of the first photographic equipment 6, so that the first spring is compressed between the mounting seat 2 and the first frame 61, so that there is a bearing capacity between the mounting seat 2 and the first frame 61, thereby realizing that the two clamping bodies 1 stably clamp the first photographic equipment 6, and avoiding the two clamping bodies 1 from shaking relative to the first photographic equipment 6 during use; when disassembling, the first frame 61 is separated from the mounting seat 2, and the elastic member 32 drives the top holding member 31 to return to its original position, with a simple structure and convenient production and assembly. Among them, the top holding member 31 can be one, or two or more top holding members 31 are arranged in parallel and spaced apart, and are arranged according to the use requirements, and are not set one by one again. Of course, an elastic pad is attached to the front end of the mounting seat 2 or the surface of the first frame 61 , and the elastic pad can be a sponge pad or a silicone pad.

[0047] Reference Figure 4 and Figure 6 The photographic kit proposed in the embodiment of the present invention also includes a positioning rod 51, which is fixedly mounted on the mounting seat 2 and extends in the up-down direction of the mounting seat 2. The top holding member 31 is provided with a sliding hole 312 extending in the front-back direction of the mounting seat 2, and the positioning rod passes through the sliding hole 312.

[0048] In this embodiment, the positioning rod 51 mounts the supporting member 31 on the mounting seat 2, the sliding hole 312 limits the range of the supporting member 31 to move forward and backward, the first spring pushes the supporting member 31 to move along the mounting seat 2 in the forward and backward direction, the sliding hole 312 has a first end and a second end opposite to each other, after assembly, the first spring supports the supporting member 31, so that the positioning rod is located at the first end of the sliding hole 312. During assembly, when the first frame 61 of the first photographic equipment 6 extends into the clamping space, the limiting portion is inserted into the positioning hole 62, the first frame 61 of the first photographic equipment 6 pushes the supporting member 31 to move toward the mounting seat 2, the first end of the sliding hole 312 gradually moves away from the positioning rod 51, and the second end of the sliding hole 312 gradually moves closer to the positioning rod 51; during disassembly, the first photographic equipment 6 is separated from the mounting seat 2, the first spring drives the supporting member 31 to return to the original position, that is, the first end of the sliding hole 312 gradually approaches to abut the positioning rod 51, and the second end of the sliding hole 312 gradually moves away from the positioning rod 51, the structure is simple, the overall weight is reduced, and the production and assembly are convenient. Of course, when there are two or more supporting members 31, the two or more supporting members 31 can be mounted on the same positioning rod 51. The overall structure is compact and occupies little space. It can be understood that they can also be mounted on different positioning rods 51, which is not limited here.

[0049] Reference Figure 2 , Figure 5 and Figure 6 The head of the clamping body 1 proposed in the embodiment of the present invention is provided with a clamping portion 11 protruding from the side of the mounting seat 2, and the clamping portion 11 is used to be clamped with the first photographic device 6. Slots 63 are respectively recessed on the left and right sides of the first frame 61, and the two clamping portions 11 are respectively inserted into the two slots 63. In order to facilitate the first frame 61 to slide into the clamping space, the two sides of the first frame 61 of the first photographic device 6 can be curved surfaces, the outer surface of the first frame 61 of the first photographic device 6 can be a plane, and the two clamping portions 11 are expanded toward one side of the first frame 61.

[0050] In this embodiment, the clamping portion 11 can prevent the first frame 61 from being separated from the front end of the mounting base 2, and the first frame 61 has two opposite sides with recessed slots 63. After assembly, a clamping portion 11 is inserted into a slot 63, and the top holding member 31 is pressed against the first frame 61, so that the clamping portion 11 fits the rear wall of the slot 63 more tightly.

[0051] Reference Figure 2 , Figure 6 and Figure 7 , an angle α is formed between the clamping portion 11 and the clamping body 1 in the embodiment of the present invention, 97°≤α≤105°.

[0052] In this embodiment, in order to make the clamping portion 11 fit more closely with the first frame 61 and reduce the virtual position, the side of the clamping portion 11 facing the clamping body 1 is an inclined surface, and there is an angle α between the clamping portion 11 and the clamping body 1. The first frame 61 is correspondingly provided with an inclined surface matching the clamping portion 11 to facilitate the assembly of the first frame 61.

[0053] In summary, the photographic kit may include two top holding members 31, and the two clamping bodies 1 may be rotatably connected to the mounting seat 2. After assembly, the cylinder 311 of the top holding member 31 extends out of the front end of the mounting seat 2, and the two clamping bodies 1 are arranged in parallel on opposite sides of the mounting seat 2. The external connection portion 21 at the rear end of the mounting seat 2 is connected to the second photographic equipment 7. In the process of installing the first photographic equipment 6 on the photographic kit, the pressing portion 13 at the rear end of the two clamping bodies 1 is pressed, so that the rear ends of the two clamping bodies 1 compress the torsion spring provided therein, and the heads of the two clamping bodies 1 are opened, so that the arc surfaces on both sides of the first frame 61 are respectively moved along The arc surfaces of the two clamping parts 11 gradually slide into between the heads of the opened clamping body 1, and at the same time, the two positioning holes 62 of the first frame 61 are respectively aligned with the limiting parts of the two top holding members 31, so that the cone at the free end of the cylinder 311 gradually extends into the positioning hole 62 until the part of the top holding member 31 abuts against the positioning groove at the opening of the positioning hole 62, and the first spring connected to the end of the top holding member 31 away from the limiting part is compressed, releasing the two pressing parts 13, and the clamping parts 11 of the two clamping bodies 1 are respectively inserted into the slots 63 on both sides of the first frame 61, thereby realizing the fixed connection between the first photographic device 6 and the second photographic device 7;

[0054] When unlocking, the pressing parts 13 at the tail ends of the two clamping bodies 1 are pressed again to make the free ends of the two pressing parts 13 approach each other, so that the tail ends of the two clamping bodies 1 compress the torsion spring provided therein, and the heads of the two clamping bodies 1 are opened. At the same time, the two clamping parts 11 are disengaged from the two slots 63, and the first frame 61 is gradually removed from the front end of the mounting seat 2 between the heads of the two opened clamping bodies 1. At the same time, the limiting parts of the two top holding members 31 are gradually disengaged from the positioning holes 62, thereby separating the first photographic equipment 6 from the first external component.

[0055] In the second embodiment, referring to Figures 7 to 13 The main difference from the first embodiment is that the photographic kit also includes a rotating connection structure, which includes a rotating damping structure 8 and a first external component for clamping and fixing the first photographic equipment 6. The first external component can be a clamping component. The rotating damping structure 8 includes a mounting member 81, a locking member 82 and a connecting member 83. One end of the locking member 82 passes through the connecting member 83 and is fixedly connected to the mounting member 81. The connecting member 83 can damp the rotation around the locking member 82. The connecting member 83 is connected to the first external component. The mounting member 81 is used to connect the second photographic equipment 7. The second photographic equipment 7 can be a handle. The handle is fixedly connected to the mounting member 81. For example, the handle is provided with a mounting groove, and two screws are provided on the mounting groove to lock the mounting member 81 on the handle. The position of the mounting member 81 in the mounting groove is adjusted to adjust the position of the rotating connection structure.

[0056] In this embodiment, the rotating connection structure can realize the rotation of the first photographic device 6 and the second photographic device 7. The structure is simple and the operation is convenient, which can achieve better filming and bring better user experience. When the handle is rotated, the mounting member 81 drives the locking member 82 to rotate relative to the connecting member 83, that is, the first photographic device 6 rotates relative to the second photographic device 7.

[0057] Further, refer to Figures 9 to 11 In order to damp the rotation smoothly, the rotation damping structure 8 also includes a sleeve 84. The sleeve 84 can be a metal part, such as copper. The sleeve 84 includes a limiting portion 841 and an extension portion 842 that are connected to each other. The diameter of the limiting portion 841 is larger than the diameter of the extension portion 842. The locking member 82 passes through the extension portion 842. The connecting member 83 is provided with a receiving groove 831 for rotatably accommodating the limiting portion 841. The receiving groove 831 can be provided with a round hole. The extension portion 842 passes through the round hole and is fixedly connected to the mounting member 81. The locking member 82 can be a screw.

[0058] Furthermore, the locking member 82 includes a screw and a screw top at one end of the screw, the screw top is accommodated in the limiting portion 841, and the screw passes through the extension portion 842 and is threadedly connected to the mounting member 81, so that the sleeve 84 is stably connected to the mounting member 81. The connecting member 83 can be connected to the mounting seat 2 by screws.

[0059] Specifically, the rotation damping structure 8 also includes two damping gaskets 85 both sleeved on the extension portion 842 , one of which is located between the limiting portion 841 and the bottom wall of the accommodating groove 831 , and the other damping gasket is located between the connecting member 83 and the mounting member 81 .

[0060] Further, refer to Fig.12 The free end of the extension portion 842 is inserted into the recessed slot 811 of the mounting member 81, and the extension portion 842 is engaged with the side wall of the slot 811, so that the extension portion 842 and the mounting member 81 cannot rotate, and the outer shape of the extension portion 842 is non-circular.

[0061] In some embodiments, the mounting member 81 can also be connected to a second external component, and the second external component is used to connect a second photographic equipment. The second external component and the mounting member 81 can be separately set, and the second external component can be provided with a quick-release component, a slide groove interface, a slide bar, an Allais structure, a snap-on structure, etc. to connect to the second photographic equipment.

[0062] To summarize, the handle is installed on the first frame 61 of the mobile phone protective frame through a rotating connection structure and a clamping assembly. When the handle needs to be rotated, the user rotates the handle relative to the connecting member 83, and the mounting member 81 drives the locking member 82 and the sleeve 84 to rotate relative to the connecting member 83, and the limiting portion 841 rotates in the accommodating groove 831.
