[0038] The quick disassembly structure is a structure that can realize the quick installation and disassembly of two devices or components. The quick disassembly structure provided in the embodiment of the present application can be widely used in many fields, for example, it can be applied to pan-tilt heads, lamps, spliced ​​brackets, displays, etc.

[0039] Please also read Figure 1 and Figure 2, the quick disassembly structure provided by the embodiment of the present application is now described. The quick disassembly structure comprises a first connecting member 1 and a second connecting member 2, the first connecting member 1 is provided with a card slot 10, the second connecting member 2 can be sleeved with the first connecting member 1 along a first direction, the second connecting member 2 is provided with an elastically retractable card block 20, the card block 20 can slide along a second direction and be inserted into the card slot 10, and the second connecting member 2 is provided with an unlocking structure 3 for allowing the card block 20 to exit the card slot 10. The first direction and the second direction are perpendicular to each other.

[0040] The quick disassembly and assembly structure is installed between two objects that need to be assembled together.

[0041] During assembly, the first connecting member 1 and the second connecting member 2 are sleeved in a first direction, and the clamping block 20 slides in a second direction and is clamped into the clamping slot 10 , so that the first connecting member 1 and the second connecting member 2 are clamped and locked.

[0042] During disassembly, the locking block 20 is withdrawn from the locking slot 10 through the unlocking structure 3, and the first connecting member 1 and the second connecting member 2 can be slidably disassembled along the first direction.

[0043] Compared with the prior art, the quick disassembly and assembly structure provided by the present application is simple to implement, and the assembly and disassembly process is completed in one step, which is simple and convenient, and does not require the use of bolts and additional auxiliary tools for disassembly and assembly.

[0044] In another embodiment of the present application, please refer to Figures 2 to 4 The first connecting member 1 has a first outer contour in the form of a regular polygon, and the second connecting member 2 has a second outer contour in the form of a regular polygon, and the second outer contour is proportionally scaled and adapted to the first outer contour. The first connecting member 1 is provided with a sleeve groove 11 into which the second connecting member 2 can be inserted, and a plurality of slots 10 are provided and are all connected to the sleeve grooves 11, and each group of slots 10 corresponds to each side of the first outer contour.

[0045] The shape of the first outer contour can be a regular quadrilateral, a regular pentagon, a regular hexagon, etc., and the shape of the second outer contour is adapted to the shape of the first outer contour. For example, when the shape of the first outer contour is a regular hexagon, the shape of the second outer contour is also a regular hexagon. In order to ensure that the first connector 1 can be sleeved outside the second connector 2, the second outer contour should be reduced in proportion. In this embodiment, the first outer contour of the first connector 1 is a regular octagon, and the second outer contour of the second connector 2 is an octagon.

[0046] When the first connector 1 and the second connector 2 are connected to each other, they can be aligned on any side, and the blocks 20 on the second connector 2 can be correspondingly inserted into the slots 10 of the first connector 1 without deliberate alignment, further improving assembly convenience.

[0047] In another embodiment of the present application, please refer to Figure 4 , the sleeve groove 11 of the first connecting member 1 has a plurality of groove walls, and each groove wall corresponds one-to-one to the side surface of the first outer contour. That is to say, assuming that the first outer contour of the first connecting member 1 is in the shape of a regular octagon, the sleeve groove 11 of the first connecting member 1 is in the shape of an octagon, and the eight groove walls correspond one-to-one to the eight side surfaces of the first outer contour. When the second connecting member 2 is sleeved in the first connecting member 1, at least three groove walls are attached walls 110, and the attached walls 110 are attached to the second outer contour, wherein the three attached walls 110 are in a triangularly opposed positional relationship. When the first connecting member 1 and the second connecting member 2 want to rotate with the first direction as the axis, the three attached walls 110 in a triangularly opposed positional relationship are tightly attached to the second outer contour, and a stable triangular relationship can be formed, so that the first connecting member 1 and the second connecting member 2 are pressed against each other without shaking, thereby having high structural stability.

[0048] It can be seen that the first connecting member 1 is a cylindrical structure. Assuming that the shape of the first outer contour is a regular octagon, the first connecting member 1 is an octagonal sleeve. At the same time, the thickness of at least three tube walls in a triangular opposing position relationship is set to be relatively slightly larger, and the thickness of the remaining tube walls is set to be relatively slightly smaller. Therefore, when the first connecting member 1 and the second connecting member 2 are mutually sleeved, the wall 110 is tightly attached to the second outer contour, and there is a gap between the remaining groove walls and the second outer contour, and the gap can facilitate the sleeve connection of the first connecting member 1 and the second connecting member 2.

[0049] In another embodiment of the present application, an elastic member 21 is provided on the second connecting member 2, and the elastic member 21 abuts between the second connecting member 2 and the block 20, and the elastic member 21 is extended in the second direction. When the first connecting member 1 is inserted into the second connecting member 2, the groove wall of the sleeve groove 11 of the first connecting member 1 pushes the block 20 to retract along the second direction and compress the elastic member 21. When the first connecting member 1 moves to the position where the slot 10 and the block 20 are aligned, the elastic member 21 releases the elastic force to push the block 20 to extend again and snap into the slot 10, thereby achieving snap-fit.

[0050] In another embodiment of the present application, please refer to Figures 2 to 4 A cavity 22 is provided in the second connecting member 2, and the blocks 20 are arranged in pairs in the cavity 22. Through holes 23 are provided on the two opposite sides of the second outer contour (on the two opposite sides of the second connecting member 2), and the two blocks 20 of each pair can be slidably inserted into the corresponding through holes 23, and an elastic member 21 is abutted between the two blocks 20 of each pair.

[0051] When the first connecting member 1 is inserted toward the second connecting member 2 along the first direction, the first connecting member 1 continues to move toward the second connecting member 2 and pushes the blocking block 20 after contacting the blocking block 20, so that the blocking block 20 is retracted into the through hole 23. When the first connecting member 1 moves to the position where the slot 10 is opposite to the through hole 23, the elastic member 21 applies elastic force to the blocking block 20 so that the blocking block 20 extends out of the through hole 23 and is stuck in the slot 10, thereby realizing the clamping connection between the first connecting member 1 and the second connecting member 2.

[0052] The blocks 20 arranged in pairs can improve the clamping strength. The number of the blocks 20 can be one pair, two pairs, etc. In this embodiment, the number of the blocks 20 is one pair. At the same time, with this arrangement, one elastic member 21 can cooperate with two blocks 20 to achieve telescopic movement.

[0053] It should be noted that, in order to ensure that the card blocks 20 can be telescopically slidable, two opposing card blocks 20 (ie, card blocks 20 in pairs) are spaced apart, and the spacing ensures that the two opposing card blocks 20 can be completely retracted into the through holes 23 at least when in contact.

[0054] In another embodiment of the present application, the elastic member 21 may specifically be a spring, an elastic rubber block, an elastic silicone block, etc. In the present embodiment, the elastic member 21 is a spring.

[0055] In another embodiment of the present application, please refer to Figure 2 and Figure 3 A wedge-shaped surface 201 is provided at the end of the clamping block 20 . During the sleeve connection between the first connecting member 1 and the second connecting member 2 , the groove wall of the sleeve groove 11 can abut against the wedge-shaped surface 201 of the clamping block 20 .

[0056] Specifically, the end of the clamping block 20 close to the corresponding through hole 23 is a clamping end 200, and the clamping end 200 is trapezoidal. The height of the clamping end 200 in the first direction gradually decreases from the end away from the through hole 23 to the end close to the through hole 23 to form a wedge surface 201. When the first connecting member 1 and the second connecting member 2 are socketed, the wedge surface 201 is located on the side of the clamping end 200 facing the first connecting member 1.

[0057] In another embodiment of the present application, please refer to Figure 3 and Figure 4 The end of the clamping block 20 away from the clamping end 200 is provided with a limiting groove 202, and the limiting groove 202 can be inserted into the end of the elastic member 21, so as to limit the elastic member 21. The two ends of the elastic member 21 are respectively located in the limiting grooves 202 of the two opposite clamping blocks 20, and the two ends of the elastic member 21 are fixedly connected to the groove walls of the corresponding limiting grooves 202.

[0058] In another embodiment of the present application, please refer to Figure 4A guiding structure is provided on the second connecting member 2, and the guiding structure is used to provide a guiding effect for the telescopic sliding of the clamping block 20 in the first direction.

[0059] In another embodiment of the present application, please refer to Figure 4 The guide structure includes two guide walls 24, both of which are supported and connected to the inner wall of the cavity 22 along the second direction, and the two guide walls 24 are arranged in parallel at intervals to form a guide slot 240, and the side of the block 20 can slide along the inner wall of the guide slot 240.

[0060] The guide wall 24 is plate-shaped and supported in the cavity 22. Both ends of the guide wall 24 are fixedly connected to the inner wall of the cavity 22 of the second connector 2. The two guide walls 24 are arranged in parallel at intervals to form a guide slot 240. The guide slot 240 communicates with two opposite through holes 23. The guide slot 240 can accommodate the card block 20, and the slot width of the guide slot 240 is slightly larger than the width of the card block 20, so as to ensure that the card block 20 can slide in the guide slot 240 and provide a guiding function.

[0061] In another embodiment of the present application, please refer to Figure 4 and Figure 5 The unlocking structure 3 includes a pushing portion 30 and a manipulation portion 31, the pushing portion 30 is connected to the manipulation portion 31, the number of the pushing portions 30 corresponds to the number of the card blocks 20, each pushing portion 30 abuts against the side of the card block 20 facing the corresponding through hole 23, and the manipulation portion 31 is movably connected to the second connecting member 2 and is at least partially located outside the second connecting member 2.

[0062] During disassembly, the pushing portion 30 is indirectly pushed by the operating portion 31 , and the pushing portion 30 pushes the corresponding card block 20 to move away from the corresponding through hole 23 , so that the card block 20 can be withdrawn from the card slot 10 , achieving unlocking and disassembly.

[0063] In order to enable the pushing portion 30 to better abut against the side of the card block 20 facing the corresponding through hole 23, an extension block 203 is provided at one end of the card block 20 away from the card end 200. The extension block 203 extends and protrudes perpendicularly to the second direction, and the pushing portion 30 abuts against the side of the extension block 203 close to the card end 200.

[0064] In another embodiment of the present application, please refer to Figure 4 and Figure 5 The operating part 31 is a sleeve structure, and the operating part 31 includes a bottom plate 310 and a side tube 311. The bottom plate 310 is supported on the bottom of the second connecting member 2. The cavity 22 of the second connecting member 2 passes through the bottom of the second connecting member 2. The cavity 22 is connected to the bottom plate 310. The side tube 311 is connected to the bottom plate 310 and can be sleeved outside the second connecting member 2. The pushing part 30 is arranged on the bottom plate 310 and extends into the second connecting member 2 to abut against the block 20.

[0065] When the operating part 31 is rotated, the pushing part 30 rotates synchronously and pushes the block 20 to move. Since the block 20 is restricted to move only along the second direction under the action of the guide structure, during the rotation of the pushing part 30, the block 20 slides in the second direction, and the pushing part 30 and the block 20 slide relative to each other in the vertical second direction.

[0066] Therefore, the extension block 203 on the clamping block 20 needs to have a sufficient length perpendicular to the second direction to ensure that the pushing portion 30 can always abut against the extension block 203 during the rotation process.

[0067] By rotating the operating part 31, the multiple pushing parts 30 can be rotated synchronously at the same time, so that the multiple clamping blocks 20 are synchronously slid and retracted into the corresponding through holes 23, and the unlocking step is completed in one step, which is easy to operate.

[0068] The diameter of the side tube 311 is larger than the first outer profile of the first connecting member 1 . When the first connecting member 1 is sleeved with the second connecting member 2 , the first connecting member 1 is sleeved outside the second connecting member 2 , and the side tube 311 is sleeved outside the first connecting member 1 .

[0069] In another embodiment of the present application, please refer to Figure 4 and Figure 5 The side tube 311 of the control part 31 is provided with a concave-convex pattern 3110 on the periphery thereof, which can increase the friction force on the periphery of the side tube 311 and facilitate the rotation of the control part 31 .

[0070] It can be seen from this that when multiple quick disassembly and assembly structures are used in combination, the concave-convex patterns 3110 on the circumference of each side tube 311 are set as tooth marks, and the control parts 31 in adjacent quick disassembly and assembly structures are engaged through the tooth marks, so that the control part 31 in one of the quick disassembly and assembly structures can be rotated, and the control parts 31 of other quick disassembly and assembly structures can be linked to rotate, thereby realizing the simultaneous unlocking and disassembly of multiple quick disassembly and assembly structures.

[0071] In another embodiment of the present application, please refer to Figure 2 and Figure 3 The bottom of the second connecting member 2 is connected to the base 4, and the control unit 31 is placed on the base 4, which plays a role of bottom support for the control unit 31. The bottom plate 310 of the control unit 31 is a hollow plate, that is, a notch is provided on the bottom plate 310, and the notch is used for connecting the second connecting member 2 with the base 4, and at the same time, it can ensure that the control unit 31 can rotate relative to the second connecting member 2. The second connecting member 2 and the base 4 can be fixed by a bolt structure.

[0072] The present application also provides a photographic device, which includes the quick disassembly structure provided in the embodiment of the present application and two mutually spliced ​​splicing units, wherein the first connecting member 1 is connected to one of the splicing units, and the second connecting member 2 is connected to the other splicing unit.

[0073] For example, the photographic equipment is a gimbal, one of the splicing units is a gimbal controller, and the other splicing unit is a bracket. The first connecting member 1 in the quick disassembly structure is fixedly connected to the gimbal controller, and the second connecting member 2 is fixedly connected to the bracket. The disassembly and assembly of the gimbal controller and the bracket is achieved through the cooperation of the first connecting member 1 and the second connecting member 2.

[0074] The photographic equipment provided in the present application adopts the quick disassembly and assembly structure provided in the embodiment of the present application, which can realize quick disassembly and assembly of two splicing units. The assembly and disassembly process is completed in one step, which is simple and convenient, and does not require the use of bolts and additional auxiliary tools for disassembly and assembly.

[0075] In another embodiment of the present application, the first connecting member 1 and one of the splicing units may be fixed by a bolt structure. The second connecting member 2 and another splicing unit may be fixed by a bolt structure.

[0076] See also Figure 1 In order to provide a shock-absorbing and buffering effect on the splicing unit, a buffer pad is arranged between the first connecting member 1 and the corresponding splicing unit. Similarly, a buffer pad may also be arranged between the second connecting member 2 and the corresponding splicing unit.

[0077] 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 and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
