Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly and specifically limited.

[0037] Referring to Figures 1 to 4 An embodiment of the present application provides a connecting bracket 100, comprising a connecting body 10, a connecting piece 20 and a plurality of suction accessories 30. The connecting piece 20 of the connecting bracket 100 is used to fix a photographic and video equipment, and the plurality of suction accessories 30 can be fixed on a plane of an external environment by suction, thereby realizing stable fixation of the photographic and video equipment on the plane of the external environment.

[0038] The connecting body 10 has first and second opposite surfaces 101 and 102. The connecting piece 20 is arranged on the first surface 101 of the connecting body 10 and is used to fix the photographic and video equipment. The plurality of suction accessories 30 are arranged on the second surface 102 of the connecting body 10 at intervals. Each suction accessory 30 comprises a housing 31 fixed to the connecting body 10, a suction disc 32 arranged on a side of the housing 31 away from the connecting body 10, and an air pipe 33 and an air pump 34 arranged inside the housing 31. The air pipe 33 is in communication with the suction disc 32, and the air pump 34 is arranged on the air pipe 33. When the air pump 34 is started, air in the suction disc 32 can be extracted through the air pipe 33, so that the suction disc 32 is fixed on the plane of the external environment by suction.

[0039] In the present application, the photographic and video equipment can include, but is not limited to, a camera, a video camera, a flash, a fill light, a flash trigger, a light effect accessory, etc.

[0040] In some embodiments of the present application, the connecting body 10 can have a plate structure. The second surface 102 of the connecting body 10 is provided with at least three mounting positions, each of which corresponds to a suction accessory 30. The connecting lines of the at least three mounting positions form a triangle or a polygon.

[0041] The three suction accessories 30 are distributed in a triangular shape relative to the connecting body 10, or the plurality of suction accessories 30 are distributed in a polygonal shape relative to the connecting body 10, which can make the connecting body 10 more evenly stressed in all directions after being connected to the plane of the external environment by the plurality of suction accessories 30, effectively resist the interference and damage of external force, reduce the risk of shaking, tilting or falling of the connecting bracket 100 due to uneven stress, and ensure the stability of the connection of the connecting bracket 100 on the plane of the external environment.

[0042] In some embodiments of the present application, the connecting body 10 comprises a body part 11 and a plurality of extension arms 12 spaced apart around the periphery of the body part 11, and the connecting member 20 is arranged on the body part 11. Adjacent two extension arms 12 are arranged at an included angle, and the mounting position is arranged close to the end of the extension arm 12 away from the body part 11.

[0043] In some examples, three extension arms 12 are arranged around the periphery of the body part 11, and the included angle between adjacent two extension arms 12 is about 120°. The end of the extension arm 12 away from the body part 11 is provided with a mounting position, and the connecting line of the mounting positions on the three extension arms 12 forms a triangle.

[0044] Such arrangement not only simplifies the structure of the connecting body 10 and realizes the lightweight of the whole connecting bracket 100, but also uniformly disperses the adsorption force between the connecting bracket 100 and the external plane through the design of the mounting positions distributed at the ends of the extension arms 12, reduces local stress concentration, improves the anti-deformation ability and durability of the whole connecting bracket 100, and prolongs the service life of the product.

[0045] In combination with Figure 3 and Figure 4 As shown in Figs. 1-2, each adsorption member 30 comprises a shell 31, a suction cup 32 arranged on the outer surface of the shell 31, and a gas pipe 33 and a gas pump 34 arranged inside the shell 31.

[0046] The suction cup 32 is arranged on the outer surface of the shell 31, and the suction cup 32 is used to be adsorbed to the plane of the external environment. In some examples, the suction cup 32 can comprise a base body and oppositely arranged outer connecting disc body and mounting disc body on both sides of the base body. The mounting disc body, the base body and the corresponding positions of the outer connecting disc body are provided with disc body openings.

[0047] A convex edge is formed on the mounting disc body and surrounds the disc body opening. The convex edge can cooperate with the ring groove on the outer surface of the shell 31 to fix the suction cup 32 on the shell 31. The base body is connected between the mounting disc body and the outer connecting disc body, and the outer connecting disc body can be made of silicone, rubber or the like, which has elasticity.

[0048] In this example, the surface of the outer connecting disc body is an arc surface, and the arc surface of the outer connecting disc body can be adsorbed and fixed to the plane of the external environment. When the arc surface of the outer connecting disc body is adsorbed to the plane of the external environment, a disc body cavity is formed between the arc surface of the suction cup 32 and the plane of the external environment.

[0049] In some examples, the connecting bracket 100 can further comprise a gasket 40 in the form of a ring. The gasket 40 is arranged between the suction cup 32 and the outer surface of the shell 31 to form a buffer between the suction cup 32 and the shell 31.

[0050] Further, the inside of the shell 31 is provided with an air pump 34 and an air pipe 33. The air pipe 33 is in communication with the suction cup 32, and the air pump 34 is arranged on the air pipe 33. The air pump 34 is activated to be able to extract air in the suction cup 32 through the air pipe 33, and the air is discharged through the air nozzle on the air pump 34, so that the suction cup 32 is in a negative pressure state with the plane of the external environment, and the suction cup 32 is adsorbed and fixed on the plane of the external environment.

[0051] In some examples, the suction accessory 30 further comprises a pressure relief valve 35 arranged in the inside of the shell 31. The pressure relief valve 35 is arranged on the air pipe 33, and the pressure relief valve 35 is activated to enable air to enter the air pipe 33, so that the suction cup 32 is separated from the plane of the external environment.

[0052] The opening and closing switch 36 of the pressure relief valve 35 is arranged on the outside of the shell 31, and the user can manually control the opening and closing switch 36 to make the pressure relief valve 35 open, so that air can enter the air pipe 33 to balance the negative pressure of the suction cup 32, and the suction cup 32 is separated from the plane of the external environment.

[0053] In some examples, the suction accessory 30 can further comprise an activation part 37 arranged on the outer surface of the shell 31. The activation part 37 is provided with a ventilation port (not shown in the figure), and the activation part 37 is in communication with the suction cup 32 through the ventilation port. The activation part 37 is used to abut against the plane of the external environment to produce elastic deformation, so that the air pump 34 is activated, and the air pump 34 extracts air in the suction cup 32 to make the suction cup 32 adsorbed and fixed on the plane of the external environment.

[0054] In addition, in some examples, the suction accessory 30 can further comprise a battery and a charging module. The battery and the charging module are arranged in the inside of the shell 31, and can be used to supply power to functional components such as the air pump 34 and the pressure relief valve 35. The shell 31 can be provided with a charging port 310, which can be a USB interface or a typc-c interface.

[0055] In other embodiments, the battery and the charging module can also be replaced by an external power supply device, that is, the power supply assembly can be external; dry batteries can also be used to replace or increase the dry battery power supply module based on the foregoing battery and charging module.

[0056] Further, in some embodiments of the present application, in combination with Figure 1 and Figure 2 As shown in the figures, each suction accessory 30 further comprises a boss seat 38 arranged on the side surface of the shell 31 away from the suction cup 32, and the boss seat 38 is provided with a threaded assembly hole 381.

[0057] The connecting body 10 is provided with a through hole 13 corresponding to the connection position of the suction accessory 30, and the connecting bracket 100 further comprises an assembly stud 50 which is arranged in the through hole 13 and screwed into an assembly screw hole 381 of the boss seat 38, so that the suction accessory 30 is detachably connected to the connecting body 10.

[0058] The suction accessory 30 is screwed to the connecting body 10 through the assembly stud 50, and when the suction accessory 30 fails, it can be disassembled from the connecting body 10 for maintenance or replacement by simply unscrewing the assembly stud 50, without the need for large-scale disassembly and adjustment of the entire connecting bracket 100, greatly reducing the maintenance cost and difficulty and improving the maintainability of the connecting bracket 100.

[0059] Moreover, the detachable connection between the suction accessory 30 and the connecting body 10 allows the suction accessory 30 to be flexibly replaced and adjusted according to actual needs. For example, different types, specifications or suction capacities of the suction accessory 30 can be replaced to adapt to diversified use requirements under different working scenarios or suction objects.

[0060] As shown in Figure 5 some embodiments of the present application, each suction accessory 30 further comprises a connecting stud 39 arranged on the side surface of the shell 31 away from the suction disc 32.

[0061] The connecting body 10 is provided with a through hole 13 corresponding to the connection position of the suction accessory 30, and the connecting bracket 100 further comprises a connecting nut 60 arranged on the first surface 101 of the connecting body 10, and the connecting stud 39 of the suction accessory 30 is arranged in the through hole 13 and screwed into the connecting nut 60, so that the suction accessory 30 is detachably connected to the connecting body 10.

[0062] The detachable connection between the suction accessory 30 and the connecting body 10 is achieved by the cooperation of the connecting stud 39 arranged on the shell 31 and the connecting nut 60, which can simplify the structure of the suction accessory 30 and the overall connecting bracket 100, and only needs to pass the connecting stud 39 through the through hole 13 of the connecting body 10 and then tighten the connecting nut 60 to complete the installation of the suction accessory 30 during installation; when disassembling, the connecting nut 60 is unscrewed, and the suction accessory 30 can be easily removed, greatly improving the installation and disassembly efficiency of the suction accessory 30.

[0063] The screwing mode of the connecting stud 39 and the connecting nut 60 in this example can provide reliable fastening force, so that the suction accessory 30 and the connecting body 10 are tightly connected together. When the photographic and video equipment is fixed to the plane of the external environment through the connecting bracket 100, the connecting bracket 100 can withstand certain external force and vibration without being easily loosened, ensuring that the suction accessory 30 always remains in the correct position, thereby ensuring the stability and reliability of the entire connecting bracket 100.

[0064] Further, in combination with Figure 6 and Figure 7 As shown in FIG. 1, in some embodiments of the present application, the shell 31 comprises a shell body 311 with an open end and a hollow interior, and an end cover 312 connected to the inner wall of the shell body 311, the inner surface of the end cover 312 and the inner wall of the shell body 311 form an installation space. The suction cup 32 is arranged on the surface of the shell body 311 away from the end cover 312, and the air pipe 33 and the air pump 34 are arranged in the installation space.

[0065] The shell body 311 and the end cover 312 form an installation space, in which the air pipe 33 and the air pump 34 are arranged, achieving a compact layout of the components in the suction accessory 30, effectively utilizing the internal space, making the structure of the entire suction accessory 30 more concise and regular, reducing the overall volume, and facilitating installation and use.

[0066] Moreover, the installation space provides a relatively closed environment for the air pipe 33 and the air pump 34, which can protect these components from external factors such as dust, moisture, collision, etc., helping to prolong the service life of the components and improve the reliability of the entire system.

[0067] In this embodiment, the shell body 311 is provided with an open end that extends outward beyond the end cover 312, and the outer surface of the end cover 312 and the inner wall of the end of the shell body 311 beyond the end cover 312 form a connection groove 201. The connection bracket 100 further comprises an adapter cover 70, which is arranged at the connection of the connection body 10 corresponding to the suction accessory 30. The adapter cover 70 can be arranged in detachable connection with the connection body 10. The adapter cover 70 is detachably clamped in the connection groove 201, so that the suction accessory 30 is detachably connected with the connection body 10.

[0068] The adapter cover 70 is detachably clamped in the connection groove 201, making the connection of the suction accessory 30 with the connection body 10 more convenient. During installation, the adapter cover 70 only needs to be aligned with the connection groove 201 and clamped in, and during disassembly, it can be easily taken out of the groove, without the need for complex tools or operations, facilitating the installation, debugging, maintenance and replacement of the suction accessory 30.

[0069] In some examples, the adapter cover 70 comprises a cover body 71 and a clamping portion 72 arranged at the edge of the cover body 71. The clamping portion 72 can be arranged in multiple, and multiple clamping portions 72 are arranged at the edge of the cover body 71 in a circumferential direction.

[0070] The shell 31 further comprises elastic pieces 314 arranged on the outer surface of the end cover 312 and having elasticity, and a retaining edge 315 arranged at the opening of the shell body 311, the retaining edge 315 being arranged corresponding to the elastic pieces 314. When the adapter cover 70 is detachably clamped in the connecting groove 201, the clamping portion 72 is clamped between the elastic pieces 314 and the retaining edge 315. The elastic pieces 314 and the retaining edge 315 can be arranged in multiple numbers, and the multiple elastic pieces 314 and the multiple retaining edges 315 are arranged one by one in correspondence, and a mounting gap can be formed between adjacent two retaining edges 315.

[0071] The multiple clamping portions 72 are arranged in a circumferential direction of the cover body 71 and correspondingly cooperate with the multiple elastic pieces 314 and the retaining edge 315, so as to provide multiple fixing points and uniformly distribute the connecting force, so that the connection between the adapter cover 70 and the connecting groove 201 is more stable, thereby enabling the connecting bracket 100 to effectively resist external force and vibration when in use, preventing the suction accessory 30 from being accidentally loosened or detached, ensuring that the suction accessory 30 and the connecting main body 10 maintain a reliable connection state, and ensuring that the connecting bracket 100 is effectively used.

[0072] When the suction accessory 30 is connected to the connecting main body 10, the clamping portion 72 can enter the connecting groove 201 through the mounting gap, and then the suction accessory 30 is rotated to enable the clamping portion 72 to be clamped between the elastic pieces 314 and the retaining edge 315, so as to achieve detachable connection and fixation of the suction accessory 30 and the connecting main body 10.

[0073] The mounting gap and the retaining edge 315 provide clear positioning and guidance for the installation of the clamping portion 72, so that the clamping portion 72 can accurately enter the connecting groove 201 and be smoothly clamped in the specified position when the suction accessory 30 is rotated. This design helps to improve the accuracy and consistency of the assembly of the suction accessory 30 and the connecting main body 10, reduces installation errors, and ensures the positional accuracy of the suction accessory 30 after installation, thereby better meeting the working requirements of the connecting bracket 100.

[0074] In some examples, the elastic piece 314 can include a transition section 3141 and a flat section 3142 connected to the transition section 3141, the transition section 3141 being connected to the outer surface of the end cover 312 and being arranged obliquely relative to the end cover 312, and the flat section 3142 being connected to one end of the transition section 3141 away from the end cover 312.

[0075] When the suction accessory 30 is connected to the connecting main body 10, the clamping portion 72 first contacts the transition section 3141 of the elastic piece 314, and the obliquely arranged transition section 3141 can provide movement guidance for the clamping portion 72, so that the clamping portion 72 gradually extrudes the elastic piece 314 along the inclined surface of the transition section 3141 when entering the connecting groove 201, causing the elastic piece 314 to elastically deform.

[0076] Compared with vertical contact, this gradual extrusion can reduce the resistance of the clamping part 72 during assembly, making the clamping process smoother. When the clamping part 72 reaches the flat section 3142, the flat section 3142 can provide stable elastic support and clamping force, ensuring that the clamping part 72 is firmly clamped between the elastic sheet 314 and the retaining edge 315, preventing accidental dislodgement of the clamping part 72.

[0077] In addition, the elastic sheet 314 can provide a certain elastic force when the clamping part 72 is clamped, acting as a buffer and compensation. On the one hand, the elastic sheet 314 can accommodate minor deviations of the clamping part 72 during installation, making clamping smoother; on the other hand, when the connecting bracket 100 is subjected to vibration or external force impact, the elastic sheet 314 can absorb part of the energy through elastic deformation, reducing damage to the connecting bracket 100, further improving the stability and reliability of the connecting bracket 100.

[0078] Further, as shown in Figure 1 some embodiments of the present application, the outer peripheral wall of the connecting piece 20 is provided with external threads, and the photographic and video equipment is provided with a connecting hole having internal threads, and the connecting piece 20 is screw-fixed with the photographic and video equipment.

[0079] This arrangement can achieve the connection or separation of the photographic and video equipment with the connecting bracket 100 by rotating the connecting bracket 100 or the photographic and video equipment, without the need for complex tools, so that the user can quickly install or replace different photographic and video equipment as needed, or conveniently disassemble it in the case of equipment maintenance, transportation, etc., improving the flexibility and convenience of use of the connecting bracket 100.

[0080] In some other embodiments of the present application, as shown in Figure 8 the connecting piece 20 can be provided with a connecting groove 201, and part of the photographic and video equipment is clamped and fixed in the connecting groove 201 of the connecting piece 20.

[0081] The connecting piece 20 can include a seat body 21 and an engaging body 22 arranged inside the seat body 21, the seat body 21 is fixed on the first surface 101 of the connecting main body 10, the seat body 21 is a groove-shaped structure, the side surface of the seat body 21 away from the connecting main body 10 forms an open notch, and the side surface of the seat body 21 is provided with a notch communicating with the internal space.

[0082] The connecting body 22 comprises a fixed arm connected with the seat body 21 and two bent arms arranged on both sides of the fixed arm, the two bent arms and the fixed arm form a connecting groove 201, and the connecting groove 201 is in communication with the notch. In some examples, the connecting piece 20 can further comprise an abutting body 23. The abutting body 23 comprises an elastic main body and elastic arms arranged on both sides of the elastic main body.
