[0030] This utility model proposes a quick-release camera clamp bracket 1000.

[0031] Please see Figures 1 to 3 In one embodiment of this utility model, the quick-release camera clamping bracket 1000 includes a quick-release latch 1, a connecting arm 2, and a camera connecting seat 3. The quick-release latch 1 includes a stationary clamping seat 11 and a movable clamping seat 12. One end of the stationary clamping seat 11 is hinged to the movable clamping seat 12, and the other end of the stationary clamping seat 11 is detachably connected to the movable clamping seat 12. The stationary clamping seat 11 has a first clamping groove 11a on the side facing the movable clamping seat 12, and the movable clamping seat 12 has a second clamping groove 12a on the side facing the stationary clamping seat 11. The connecting arm 2 connects the stationary clamping seat 11 and the camera connecting seat 3, and is hinged to both the stationary clamping seat 11 and the camera connecting seat 3. The first clamping groove 11a and the second clamping groove 12a can be U-shaped, V-shaped, or other shapes. Anti-slip pads 15 can be attached inside the grooves to enhance the friction with the tubular object to be clamped.

[0032] In this embodiment, the detachable connection between the other end of the stationary clamp 11 and the movable clamp 12 can be achieved through a quick-release locking mechanism. The locking mechanism is located on the stationary clamp 11 and is used to quickly lock and unlock both. The locking mechanism includes a locking button and a locking pin 131. The locking button is located on the stationary clamp 11, while the locking pin 131 passes through corresponding holes on the stationary clamp 11 and the movable clamp 12. When it is necessary to fix the camera, simply close the stationary clamp 11 and the movable clamp 12, press the locking button to extend the locking pin 131, and lock it through the hole. For disassembly, press the locking button again to retract the locking pin 131, easily separating the stationary clamp 11 and the movable clamp 12.

[0033] The detachable connection between the other end of the stationary clamp 11 and the movable clamp 12 can also be achieved through a quick-release locking mechanism. A press-type latch structure is provided on the stationary clamp 11, which includes an elastic arm and a latching claw. The elastic arm is connected to the stationary clamp 11, and the latching claw is located at the end of the elastic arm for interaction with the corresponding part of the movable clamp 12. A groove matching the latching claw of the stationary clamp 11 is designed on the movable clamp 12, and the groove has two states: a locked state and a released state. When the user needs to fix the camera, the movable clamp 12 and the stationary clamp 11 are closed, so that the latching claw of the stationary clamp 11 is inserted into the groove of the movable clamp 12. The user presses the elastic arm, and the latching claw enters the locked state of the groove under the action of elastic force, thereby achieving a tight connection between the stationary clamp 11 and the movable clamp 12. When the user needs to remove the camera, the elastic arm is pressed again, causing the latching claw to exit the locked state of the groove and enter the released state. At this time, the movable clamp 12 can be separated from the stationary clamp 11 under the action of the elastic arm.

[0034] The quick-release camera clamp bracket 1000 of this utility model includes a quick-release buckle 1, a connecting arm 2, and a camera connecting seat 3. The quick-release buckle 1 includes a stationary clamp 11 and a movable clamp 12. One end of the stationary clamp 11 is hinged to the movable clamp 12, and the other end of the stationary clamp 11 is detachably connected to the movable clamp 12. The stationary clamp 11 has a first clamping groove 11a on the side facing the movable clamp 12, and the movable clamp 12 has a second clamping groove 12a on the side facing the stationary clamp 11. The connecting arm 2 connects the stationary clamp 11 and the camera connecting seat 3, and is hinged to the stationary clamp 11 and the camera connecting seat 3 respectively. When installing this quick-release camera clamp bracket 1000, simply rotate the movable clamp 12 to close the stationary clamp 11 and the movable clamp 12, and lock the closed joint to fix the object to be clamped between the first clamping groove 11a and the second clamping groove 12a. When disassembling, simply loosen the closed joint and rotate the movable clamp 12. In this way, it is not necessary to completely separate the stationary clamp 11 and the movable clamp 12, which can achieve quick assembly and disassembly and improve the assembly and disassembly efficiency of the camera clamp bracket.

[0035] Further, please refer to Figures 1 to 3In one embodiment of this utility model, the quick-release lever 1 further includes a locking device 13, which includes a locking pin 131 and a sleeve 132. The stationary clamp 11 has a first connecting end 111 and a second connecting end 112, and the movable clamp 12 has a third connecting end 121 and a fourth connecting end 122. A first clamping groove 11a is provided between the first connecting end 111 and the second connecting end 112, and a second clamping groove 12a is provided between the third connecting end 121 and the fourth connecting end 122. The connecting end 111 is hinged to the third connecting end 121, the second connecting end 112 abuts against the fourth connecting end 122, the fourth connecting end 122 is provided with a locking hole 122a, the side wall of the locking hole 122a is provided with a clearance opening 122b, the locking pin 131 passes through the locking hole 122a and is hinged to the second connecting end 112, the sleeve 132 is located on the side of the fourth connecting end 122 facing away from the second connecting end 112, and the inner wall of the sleeve 132 is screwed to the outer wall of the locking pin 131.

[0036] In this embodiment, one end of the locking pin 131 is hinged to the second connecting end 112. When the stationary clamp 11 and the movable clamp 12 are closed, the fourth connecting end 122 abuts against the second connecting end 112. The locking pin 131 can rotate around the hinge and pass through the clearance opening 122b into the locking hole 122a. The outer wall of the locking pin 131 is provided with external threads, and the inner wall of the sleeve 132 is provided with internal threads. The sleeve 132 rotates along the outer wall of the locking pin 131 towards the fourth connecting end 122 until it abuts against the fourth connecting end 122, thereby locking the fourth connecting end 122 to the second connecting end 112. By providing the locking device 13 and the locking hole 122a, a detachable connection between the second connecting end 112 and the fourth connecting end 122 is achieved. This connection method is not only convenient and quick, but also more robust and reliable.

[0037] It should be noted that, Figures 1 to 5 In order to show all the structures, the sleeve 132 and the movable clamp 12 are not in contact. However, the movable clamp 12 can rotate around the axis to make the second connecting end 112 abut against the fourth connecting end 122, and the sleeve 132 can rotate along the thread to abut against the fourth connecting end 122, and press the fourth connecting end 122 against the second connecting end 112.

[0038] Further, please refer to Figures 1 to 3In one embodiment of this utility model, the outer wall of the sleeve 132 is provided with a protrusion 133. In this embodiment, the protrusion 133 extends radially along the sleeve 132, that is, the protrusion 133 can rotate around the axial direction of the sleeve 132. By utilizing the lever principle, the force required to twist the sleeve 132 is saved, and the sleeve 132 can be twisted by hand without the aid of wrenches or other tools, which improves the convenience of this quick-release camera clamp bracket 1000.

[0039] Further, please refer to Figures 4 to 5 In one embodiment of the present invention, the static clamp 11 is provided with a first hinged engagement part on the side opposite to the moving clamp 12, and the connecting arm 2 is provided with a second hinged engagement part at one end near the static clamp 11, and / or, the camera connecting seat 3 is provided with a first hinged engagement part, and the connecting arm 2 is provided with a second hinged engagement part at one end near the camera connecting seat 3, wherein the first hinged engagement part and the second hinged engagement part are hinged together.

[0040] In this embodiment, the first and second hinged joints can be configured as universal joints, which consist of two fork-shaped components. Each fork-shaped component is connected to a cross-shaped structure, with each fork-shaped component connected to opposite ends of the cross-shaped structure. This configuration allows rotation in two mutually perpendicular planes, and the two fork-shaped components can rotate simultaneously.

[0041] The first and second hinged parts can also be configured as translational hinges, where one of the first and second hinged parts is a protrusion 133 and the other is a groove, with the protrusion 133 extending into the groove and connected to the inner wall of the groove via a pivot. This configuration allows rotation in two mutually perpendicular planes.

[0042] Specifically, to increase the adjustability range of connecting arm 2, please refer to... Figures 4 to 5 In one embodiment of this utility model, one of the first hinged fitting portion and the second hinged fitting portion is a universal ball joint, and the other is a hinge cavity adapted to the universal ball joint. The universal ball joint can provide almost all degrees of freedom of movement, including rotation and tilt, which allows the user to very easily adjust the camera to any desired angle.

[0043] Further, please refer to Figures 4 to 5In one embodiment of this utility model, the connecting arm 2 includes a first clamping arm 21 and a second clamping arm 22, which are detachably connected. The first clamping arm 21 has a first arc-shaped groove 21a at one end near the stationary clamping seat 11, and the second clamping arm 22 has a second arc-shaped groove 22a at one end near the stationary clamping seat 11. The first arc-shaped groove 21a and the second arc-shaped groove 22a are arranged opposite to each other, and a first hinge cavity 2a is formed between the bottom wall of the first arc-shaped groove 21a and the bottom wall of the second arc-shaped groove 22a. A first universal ball joint 14 is provided on the side of the stationary clamping seat 11 facing away from the movable clamping seat 12, and the first universal ball joint 14 is hinged to the inner wall of the first hinge cavity 2a. In this embodiment, the first clamping arm 21 and the second clamping arm 22 are detachably connected by bolts, clips, slide rails, and slide grooves. Disassembling the connecting arm 2 into the first clamping arm 21 and the second clamping arm 22 facilitates production and assembly, as well as the replacement of the universal ball joint during maintenance. The omnidirectional ball joint provides almost omnidirectional freedom of movement, including rotation and tilt, which allows users to easily adjust the camera to any desired angle.

[0044] Further, please refer to Figures 4 to 5 In one embodiment of this utility model, the first clamping arm 21 has a third arc-shaped groove 21b at one end near the camera connecting seat 3, and the second clamping arm 22 has a fourth arc-shaped groove 22b at one end near the camera connecting seat 3. The third arc-shaped groove 21b and the fourth arc-shaped groove 22b are arranged opposite to each other, and a second hinge cavity 2b is formed between the bottom wall of the third arc-shaped groove 21b and the bottom wall of the fourth arc-shaped groove 22b. The camera connecting seat 3 has a second universal ball joint 31, which is hinged to the inner wall of the second hinge cavity 2b. In this embodiment, the first clamping arm 21 and the second clamping arm 22 are detachably connected by bolts, buckles, slide rails, and slide grooves. Disassembling the connecting arm 2 into the first clamping arm 21 and the second clamping arm 22 facilitates production and assembly, as well as the replacement of the universal ball joint during maintenance. The universal ball joint can provide almost omnidirectional freedom of movement, including rotation and tilt, which allows the user to easily adjust the camera to any desired angle.

[0045] Further, please refer to Figures 4 to 5In one embodiment of this utility model, the connecting arm 2 further includes a locking screw 23 and a knob 24. The first clamping arm 21 is provided with a first screw 141 hole, and the second clamping arm 22 is provided with a second screw 311 hole 22c. The locking screw 23 passes through the first screw 141 hole and the second screw 311 hole 22c in sequence. The knob 24 is located on the side of the second clamping arm 22 facing away from the first clamping arm 21 and is screwed to the locking screw 23. The knob 24 abuts against the periphery of the second screw 311 hole 22c. In this embodiment, the knob 24 drives the locking screw 23 to rotate, causing the first clamping arm 21 and the second clamping arm 22 to clamp or loosen the first universal ball joint 14 and the second universal ball joint 31, so as to adjust the angle of the connecting arm 2 and thus adjust the spatial position of the camera. The knob 24 reduces the force required to turn the locking screw 23, allowing the screw to be turned by hand without the aid of a wrench or other tools, thus improving the convenience of this quick-release camera clamp 1000.

[0046] For further details, please refer to Figures 4 to 5 In one embodiment of this utility model, the connecting arm 2 further includes a spring 25, which is sleeved on the locking screw 23 and connects the knob 24 to the periphery of the hole 22c of the second screw 311. In this embodiment, the spring 25 can maintain a certain tension to ensure that the first clamping arm 21 and the second clamping arm 22 will not completely separate when the knob 24 is loosened, thereby maintaining the stability of the connecting arm 2. This also helps to maintain a certain clamping force when the locking screw 23 is loosened to adjust the angle of the connecting arm 2, preventing the universal ball joint from disengaging from the hinge cavity and causing the camera to fall and be damaged.

[0047] Further, please refer to Figure 3 In one embodiment of this utility model, the stationary clamp 11 has a first threaded hole 11b on the side opposite to the movable clamp 12. The first universal ball joint 14 is connected to a first screw 141, and the first screw 141 is screwed into the inner wall of the first threaded hole 11b. Alternatively, the camera connector 3 has a second threaded hole 31a, and the second universal ball joint 31 is connected to a second screw 311, which is screwed into the inner wall of the second threaded hole 31a. In this embodiment, the connection between the first universal ball joint 14 and the stationary clamp 11 via the first screw 141 and the first threaded hole 11b facilitates disassembly and replacement. If the first universal ball joint 14 is damaged due to friction, it can be replaced individually without replacing the entire clamping bracket. The second universal ball joint 31 is similarly handled, and will not be described further here.
