DETAILED DESCRIPTION

[0023] In the following, the utility model is further described in combination with the drawings and the specific implementation, and it should be noted that, under the premise of no conflict, the following described embodiments or technical features can be combined to form new embodiments.

[0024] ​​​It should be noted that all directional indications (such as up, down, left, right, front, back, inner, outer, top, bottom, etc.) in the embodiments of the present application are only used to explain the relative positional relationship between components, etc. in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0025] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or a middle element can be present at the same time. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or a middle element can be present at the same time.

[0026] As shown in Figure 1 An embodiment of the present application provides a quick release kit 10 for mounting a shooting device, such as a camera, to an external element to free the user's hands. The quick release kit 10 includes a mounting plate 12 for mounting the shooting device and a base 14 located on one side of the mounting plate 12. In use, the quick release kit 10 forms a clamping space between the mounting plate 12 and the base 14, and the quick release kit 10 can clamp the external element through the clamping space, so as to clamp and mount the shooting device to the external element. The present application takes the clamped object, i.e. the shoulder strap of a backpack, as an example for illustration.

[0027] It should be noted that the shooting device mounted to the mounting plate 12 can mean that the shooting device is directly mounted on the mounting plate 12, or indirectly mounted on the mounting plate 12 through an intermediate element, such as a quick release plate, i.e. the shooting device is mounted on the quick release plate, and the quick release plate is mounted to the mounting plate 12.

[0028] The side of the mounting plate 12 away from the base 14 is provided with a mounting portion 16 for mounting the shooting device. In an optional example, the shooting device is mounted on the quick release plate, and the quick release plate is detachably mounted to the mounting portion 16, so as to detachably mount the shooting device to the mounting portion 16. Specifically, the mounting portion 16 is a sliding groove, and the quick release plate is mounted to or separated from the mounting portion 16 by sliding.

[0029] Please refer to Figure 1 and Figure 2 In an embodiment, the mounting plate 12 has opposite first and second ends 18 and 20, the first end 18 is connected to the base 14 through a connecting structure 22, the connecting structure 22 can prevent the first end 18 from being separated from the base 14, and the second end 20 is matched with the base 14 through a locking structure 24. The locking structure 24 can move relative to the second end 20 to have a locked state and an unlocked state, that is, the locking structure 24 includes the locked state and the unlocked state, and the locking structure 24 can switch between the locked state and the unlocked state by moving relative to the second end 20.

[0030] In the locked state, the second end 20 is connected with the base 14 through the locking structure 24, and the first end 18 and the second end 20 of the mounting plate 12 are kept relatively fixed with the base 14, so that the locking structure 24 can be kept in the locked state after the quick release assembly 10 is installed on the shoulder strap, and the mounting plate 12 and the base 14 can stably clamp the shoulder strap, so as to stably install the quick release assembly 10 on the shoulder strap. In the unlocked state, the locking structure 24 is separated from the base 14, and the mounting plate 12 can move relative to the base 14 so as to make the shoulder strap enter or exit between the mounting plate 12 and the base 14.

[0031] In an optional example, the mounting plate 12 has a length direction and a thickness direction perpendicular to each other, the first end 18 and the second end 20 are respectively located at two ends of the mounting plate 12 in the length direction, and the base 14 is located at one side of the mounting plate 12 in the thickness direction, that is, the mounting plate 12 and the base 14 are arranged along the thickness direction.

[0032] As shown in Figure 2 The connecting structure 22 includes a plurality of limiting grooves 26 provided on one of the first end 18 of the mounting plate 12 and the base 14 and a limiting piece 28 provided on the other one, the plurality of limiting grooves 26 are communicated with each other, and the plurality of limiting grooves 26 are arranged at intervals along the arrangement direction of the mounting plate 12 and the base 14, and the limiting piece 28 can selectively cooperate with one limiting groove 26. Along the arrangement direction of the mounting plate 12 and the base 14, a clamping space can be formed between the mounting plate 12 and the base 14. Since the plurality of limiting grooves 26 are arranged along the arrangement direction, when the limiting piece 28 cooperates with different limiting grooves 26, the relative position of the mounting plate 12 and the base 14 in the arrangement direction will change, so that the distance between the mounting plate 12 and the base 14 changes, thereby adjusting the size of the clamping space. In this embodiment, the limiting grooves 26 are provided on the mounting plate 12, and the plurality of limiting grooves 26 are arranged at intervals along the thickness direction of the mounting plate 12, and the limiting piece 28 is correspondingly provided on the base 14.

[0033] When the locking structure 24 is in the locked state, the second end 20 of the mounting plate 12 is connected with the base 14 through the locking structure 24, so that the second end 20 is kept relatively fixed with the base 14, and the limiting piece 28 is located in a limiting slot 26, so that the first end 18 is also kept relatively fixed with the base 14, thereby the mounting plate 12 as a whole is kept relatively fixed with the base 14. When the locking structure 24 is in the unlocked state, the locking structure 24 releases the locking of the second end 20, so that the mounting plate 12 can move relative to the base 14 under the action of an external force, and the limiting piece 28 switches between different limiting slots 26, i.e., moves from one limiting slot 26 to another limiting slot 26, so as to adjust the size of the clamping space between the mounting plate 12 and the base 14, thereby the quick release kit 10 can be adapted to objects with different thicknesses by adjusting the size of the clamping space, thereby widening the application scenarios of the quick release kit 10.

[0034] In an optional example, in the locked state, the second end 20 of the mounting plate 12 is fixedly connected with the base 14 through the locking structure 24, and in the unlocked state, the locking structure 24 is connected with the base 14 and separated from the second end 20, thereby releasing the locking of the second end 20.

[0035] Each limiting slot 26 includes oppositely arranged opening ends 261 and limiting ends 262, and the opening ends 261 of the plurality of limiting slots 26 are directed to the same side, the opening ends 261 are used for the limiting piece 28 to enter or exit the limiting slot 26, and the plurality of limiting slots 26 are communicated through the opening ends 261, so that the limiting piece 28 switches between different limiting slots 26. In the locked state, the limiting piece 28 abuts against the inner wall of the limiting end 262, so as to enhance the stability of the limiting piece 28 in the limiting end 262, reduce the risk of shaking of the limiting piece 28 in the limiting end 262, and improve the stability in the locked state, and also facilitate the mounting plate 12 to rotate relative to the base 14 with the limiting piece 28 as the axis.

[0036] The limiting piece 28 is in a cylindrical shape, and the circumferential surface of the limiting piece 28 is an arc-shaped surface, and the size of the opening end 261 is greater than the radial size of the limiting piece 28, so that the limiting piece 28 can freely pass through the opening end 261, and move from the limiting slot 26 to the outside of the limiting slot 26 through the opening end 261, or move from the outside of the limiting slot 26 to the inside of the limiting slot 26 through the opening end 261.

[0037] The inner wall of the limiting end 262 away from the opening end 261 is an arc surface 263, which is in contact with the outer surface of the limiting member 28 when the limiting member 28 is located in the limiting end 262, so as to achieve the limiting effect. In an optional example, the circumferential dimension of the arc surface 263 is 0.4 to 0.5 times the axial dimension of the limiting member 26 along the circumference of the limiting member 28, which can prevent the circumferential length of the contact part from being too long to hinder the limiting member 28 from entering or exiting the limiting end 262, and can also prevent the circumferential length of the contact part from being too small to cause poor limiting effect on the limiting member 28.

[0038] When the locking structure 24 is in the unlocked state and the limiting member 28 is located in the limiting end 262, the mounting plate 12 can rotate relative to the base 14 with the limiting member 28 as the axis to form an opening between the second end 20 and the base 14, so as to load the clamped object from the opening into the clamping space. When the first end 18 rotates relative to the base 14 with the limiting member 28 as the axis, the second end 20 is driven to move relative to the base 14, so that the second end 20 moves away from or approaches the base 14, and the distance between the second end and the base 14 is adjusted, i.e. the size of the opening is adjusted, so as to enable the shoulder strap to enter or exit the clamping space.

[0039] The connecting structure 22 further comprises a communication groove 32, which is located on one side of the plurality of limiting grooves 26, the limiting end 262 is located on the side of the opening end 261 away from the communication groove 32, the communication groove 32 extends along the arrangement direction of the plurality of limiting grooves 26, and the opening end 261 of each limiting groove 26 communicates with the communication groove 32. In the unlocked state, the limiting member 28 can enter the communication groove 32 from the limiting groove 26 and move in the communication groove 32, so that the limiting member 28 moves from one limiting groove 26 to another limiting groove 26. In the process of adjusting the size of the clamping space, the mounting plate 12 can be moved relative to the base 14, so that the limiting member 28 moves from the limiting end 262 to the opening end 261 of the limiting groove 26, enters the communication groove 32 through the opening end 261, moves in the communication groove 32 to a position corresponding to the target limiting groove 26, and enters the target limiting groove 26 through the opening end 261, so that the limiting member 28 moves to the limiting end 262 of the target limiting groove 26.

[0040] Please refer to Figure 2 and Figure 3In an embodiment, the limiting protrusions 34 are formed between the adjacent limiting grooves 26, i.e., the adjacent limiting grooves 26 are separated by the limiting protrusions 34. One end of the limiting protrusion 34 is connected to the limiting end 262, and the upper surface (i.e., the surface away from the base 14 in the thickness direction of the mounting plate 12) of the limiting protrusion 34 extends obliquely from the curved surface 263 of the limiting groove 26 towards the opening end 261, so that the two ends of the limiting protrusion 34 have a height difference in the thickness direction of the mounting plate 12, thereby limiting the limiting member 28 located in the limiting end 262, reducing the risk of the limiting member 28 exiting from the limiting groove 26 when it does not need to switch to a different limiting groove 26, and enhancing the stability of the quick-release assembly 10 in the locked state and when the mounting plate 12 rotates relative to the base 14.

[0041] Optionally, the number of limiting protrusions 34 is multiple, and the multiple limiting protrusions 34 are arranged in the thickness direction of the mounting plate 12.

[0042] In an embodiment, the base 14 is provided with two extension portions 38 near one end of the first end 18. The two extension portions 38 are oppositely arranged, thereby forming a mounting groove 40 between the two extension portions 38. The first end 18 of the mounting plate 12 is provided with a protruding portion 42, which is mounted to the mounting groove 40. The opposite sides of the protruding portion 42 are respectively provided with the connecting structure 22 between the corresponding extension portion 38, so that the protruding portion 42 is more balanced in force, thereby enhancing the stability of the connection between the mounting plate 12 and the base 14.

[0043] The opposite sides of the protruding portion 42 are respectively provided with the limiting groove 26, and the two extension portions 38 are respectively provided with the limiting member 28. One end of the two limiting members 28 protrudes out of the extension portion 38 and is inserted into the corresponding limiting groove 26.

[0044] Please refer to Figure 2 and Figure 4 In an embodiment, the locking structure 24 is rotationally connected to the base 14, i.e., the locking structure 24 is at least partially rotatable relative to the base 14, so that the locking structure 24 moves relative to the second end 20, thereby switching between the locked state and the unlocked state. The unlocking or locking is achieved by rotation, which is simple to operate and convenient for users to use.

[0045] The second end 20 of the mounting plate 12 away from the first end 18 side is recessed to form a locking groove 44, and the locking structure 24 can rotate relative to the base 14 to enter or exit the locking groove 44 to form a locked state or an unlocked state, respectively, that is, when the locking structure 24 rotates from the locking groove 44 away from the first end 18, the locking structure 24 can exit from the locking groove 44, so that the locking structure 24 is switched from the locked state to the unlocked state; when the locking structure 24 rotates from the outside of the locking groove 44 towards the first end 18, the locking structure 24 can enter the locking groove 44, so that the locking structure 24 is switched from the unlocked state to the locked state. The locking groove 44 extends to the outer surface of the second end 20 away from the first end 18, thereby forming an opening on the side of the locking groove 44 away from the second end 20 to allow the locking structure 24 to enter or exit, and during the disassembly and assembly of the quick release kit 10, the user only needs to rotate the locking structure 24 away from or towards the first end 18 to switch between the locked state and the unlocked state, which is simple and convenient for the user to use.

[0046] The locking structure 24 includes a connecting shaft 46, a connecting piece 48, and a locking piece 50, the connecting piece 48 is rotatably connected to the base 14 through the connecting shaft 46, and the locking piece 50 is movably connected to the connecting piece 48, so that the locking piece 50 and the connecting piece 48 can move relative to each other to adjust the distance between the locking piece 50 and the connecting shaft 46. The locking piece 50 is substantially T-shaped, and in the locked state, the locking piece 50 is partially located in the locking groove 44 and partially located on the side of the second end 20 away from the base 14 and presses against the second end 20, tightly pressing the second end 20 of the mounting plate 12 to form a locking effect.

[0047] The base 14 is provided with an avoiding groove 52, and the connecting shaft 46 is installed on the base 14 and passes through the avoiding groove 52, and one end of the connecting piece 48 is located in the avoiding groove 52 and is rotatably connected to the connecting shaft 46. The end of the connecting piece 48 located in the avoiding groove 52 is spherical, and the connecting shaft 46 movably passes through the spherical end. The spherical end of the connecting piece 48 located in the avoiding groove 52 is provided, which is convenient for connection with the connecting shaft 46, and can also reduce the risk of interference between the connecting piece 48 and the base 14 when the connecting piece 48 rotates around the connecting shaft 46.

[0048] It can be understood that the locking piece 50 and the connecting piece 48 can move relative to each other, which can be through screwing the locking piece 50 with the connecting piece 48, or through sliding the locking piece 50 with the connecting piece 48, as long as the distance between the locking piece 50 and the connecting shaft 46 changes when the locking piece 50 moves relative to the connecting piece 48.

[0049] In an alternative example, the locking member 50 comprises a first locking member 54 and a second locking member 56. The first locking member 54 is provided with a through hole 58, and the connecting member 48 is inserted into the through hole 58 from one side of the first locking member 54 and is in sliding fit with the first locking member 54, so that the first locking member 54 can slide relative to the connecting member 48 to adjust the distance between the first locking member 54 and the connecting shaft 46. The second locking member 56 is inserted into the through hole 58 from the other side of the first locking member 54 and is in threaded fit with the connecting member 48. When the second locking member 56 is rotated to abut against the end of the first locking member 54 away from the connecting member 48, the second locking member 56 can limit the sliding of the first locking member 54 relative to the connecting member 48. When the second locking member 56 is disconnected from the connecting member 48 or is rotated to be spaced apart from the end of the first locking member 54 away from the connecting member 48 by a certain distance, the second locking member 56 can slide relative to the connecting member 48.

[0050] The first locking member 54 is substantially T-shaped and comprises a connecting portion 60 and an abutting portion 62 located at one end of the connecting portion 60. The through hole 58 penetrates the connecting portion 60 and the abutting portion 62, and the connecting member 48 is movably inserted into the through hole 58 in the connecting portion 60 to be in sliding fit with the connecting portion 60. The second locking member 56 is inserted into the through hole 58 in the abutting portion 62 and is inserted into the connecting portion 60 to be in threaded fit with the connecting member 48. In the locked state, the connecting portion 60 of the first locking member 54 is located in the locking groove 44, the abutting portion 62 is located on the side of the mounting plate 12 away from the base 14, the second locking member 56 is in threaded fit with the connecting member 48 and abuts against the side of the abutting portion 62 away from the connecting portion 60, so as to tightly press the abutting portion 62 against the mounting plate 12 to limit the movement of the mounting plate 12 and form the locking effect. When the second locking member 56 is disconnected from the connecting member 48 or is rotated to be spaced apart from the end of the first locking member 54 away from the connecting member 48 by a certain distance, the first locking member 54 can slide relative to the connecting member 48 to adjust the distance between the abutting portion 62 and the connecting member 48 to adapt to the position change of the mounting plate 12 after the quick release sleeve assembly 10 clamps the shoulder strap.

[0051] As Figure 2As shown, in an embodiment, the mounting plate 12 is provided with a mutually cooperating elastic sliding block 64 and elastic locking member 66, which are respectively matched with the mounting plate 12, the elastic sliding block 64 is used to drive the elastic locking member 66 to protrude into or exit from the mounting portion 16. The elastic sliding block 64 is used for the user to press to slide relative to the mounting plate 12, and the elastic locking member 66 is used to extend and retract relative to the mounting portion 16 under the action of the elastic sliding block 64, when it extends into the mounting portion 16, the elastic locking member 66 is matched with the corresponding locking structure on the shooting device or the quick release plate, so as to enhance the stability of the shooting device mounted on the mounting portion 16, when the elastic locking member 66 retracts into the mounting plate 12, that is, exits from the mounting portion 16, the elastic locking member 66 is disengaged from the corresponding locking structure on the shooting device or the quick release plate, so as to separate the shooting device from the mounting portion 16. The user can make the elastic locking member 66 form a locking cooperation or disengage cooperation with the locking structure by pressing the elastic sliding block 64, which is simple in operation and convenient for the shooting device to be disassembled and assembled.

[0052] The elastic sliding block 64 includes a sliding block and a first elastic member matched with the sliding block, the elastic locking member 66 includes a locking member and a second elastic member matched with the locking member, one end of the sliding block protrudes from the outside of the mounting plate 12 for the user to press, the other end is connected with the first elastic member, when the user presses the sliding block to slide towards the inside of the mounting plate 12, the first elastic member is extruded to be compressed and deformed, and the elastic recovery force opposite to the extrusion force is formed on the sliding block, when the sliding block moves to the locking member inside the mounting plate 12, the locking member is extruded to move away from the mounting portion 16, the second elastic member is located on the side of the locking member away from the mounting portion 16, so that when the locking member moves away from the mounting portion 16, the second elastic member is extruded to be compressed and deformed, and the elastic recovery force is generated on the locking member to move towards the mounting portion 16, when the user releases the sliding block, the sliding block slides towards the outside of the mounting plate 12 under the action of the first elastic member, and gradually stops extruding the locking member, the locking member moves towards the mounting portion 16 under the action of the second elastic member, and finally the locking member protrudes into the mounting portion 16.
