[0034] Please refer to Figures 1 to 7 , the clamping structure includes a fixed seat body 10 and a movable clamping seat 20. The movable clamping seat 20 is slidably arranged on the fixed seat body 10. The fixed seat body 10 and the movable clamping seat 20 enclose a profiled clamping groove 10a for accommodating and limiting a quick-installation plate.

[0035] Among them, the clamping structure is provided with a push rod 30. One end of the push rod 30 is connected to the movable clamping seat 20, and the other end is exposed outside the fixed seat body 10. When the push rod 30 is driven to move towards the fixed seat body 10, the movable clamping seat 20 moves away from the fixed seat body 10.

[0036] In the technical solution of the present utility model, the clamping structure includes a fixed seat body 10 and a movable clamping seat 20. The movable clamping seat 20 is slidably arranged on the fixed seat body 10. The fixed seat body 10 and the movable clamping seat 20 enclose a profiling clamping groove 10a for accommodating and limiting the quick-release plate. In order to enable the movable clamping seat 20 to move relative to the fixed seat body 10, the clamping structure is provided with a push rod 30. One end of the push rod 30 is connected to the movable clamping seat 20, and the other end is exposed outside the fixed seat body 10. Thus, when it is necessary to take out the quick-release plate from the profiling clamping groove 10a, only need to push the push rod 30, and the push rod 30 drives the movable clamping seat 20 to move away from the fixed seat body 10, then the quick-release plate can be quickly taken out, thereby improving the disassembly convenience of the quick-release plate.

[0037] The fixed seat body 10 is provided with a detachable fixing structure such as a bolt or a buckle at the bottom, so as to be fixed on the camera tripod head to form an integral body with the camera bracket, preventing looseness between the clamping structure and the camera bracket; the overall shape of the fixed seat body 10 is an encircling cofferdam shape, with a notch on one side for the movable clamping seat 20 to pass back and forth, and a channel structure on the other side for the push rod 30 to pass back and forth. Thus, the function of quickly taking out the quick-release plate can be realized by pushing the push rod 30.

[0038] The movable clamping seat 20 includes an integral bottom plate structure and an enclosing convex block structure arranged at the end of the bottom plate structure. When the bottom plate structure is arranged on the fixed seat body 10, the enclosing convex block structure fills the notch of the fixed seat body 10, so that the movable clamping seat 20 and the fixed seat body 10 can enclose a profiling clamping groove 10a. The profiling clamping groove 10a is used for accommodating and limiting the quick-release plate. After the quick-release plate is installed in the profiling clamping groove 10a, the groove wall of the profiling clamping groove 10a can abut against the outer wall of the quick-release plate, thereby improving the clamping stability. Further, by pushing the push rod 30, the size of the accommodating groove 10a1 can be controlled to quickly take out the quick-release plate.

[0039] The push rod 30 may have a cross-section in the shape of a circle, a square, or other shapes. The channel structure on the fixed base 10 through which the push rod 30 passes is shaped to fit the cross-sectional shape of the push rod 30, thereby improving the assembly accuracy between the push rod 30 and the fixed base 10 and avoiding problems such as shaking or deviation of the push rod 30. One end of the push rod 30 passes through the channel structure of the fixed base 10 to connect to the movable clamping seat 20, and the other end is exposed from the fixed base 10 to serve as the driving end. Among them, when the push rod 30 is driven to move towards the fixed base 10, the movable clamping seat 20 moves away from the fixed base 10. When the minimum opening area of the profiling clamping groove 10a is greater than the maximum area of the quick-release plate, the quick-release plate can be taken out. During the taking-out process, only the driving end of the push rod 30 needs to be pushed, and the linear motion of the push rod 30 is converted into the linear motion of the movable clamping seat 20 at a one-to-one stroke ratio, thereby improving the operational convenience of disassembling the quick-release plate.

[0040] In one embodiment, as Figure 3 and Figure 4 and Figure 7 shown, the clamping structure further includes a partition plate 11. The cross-sectional shape of the partition plate 11 is adapted to the cross-sectional shape of the profiling clamping groove 10a. The partition plate 11 is disposed in the profiling clamping groove 10a. In this way, the profiling clamping groove 10a is divided into an upper and a lower accommodating groove 10a1 and a movable cavity 10a2. The accommodating groove 10a1 can accommodate and position the quick-release plate, and the movable cavity 10a2 allows the movable clamping seat 20 and the push rod 30 to move, making full use of the accommodating space of the profiling clamping groove 10a and avoiding movement interference between the quick-release plate and the movable clamping seat 20 and the push rod 30.

[0041] Furthermore, as Figures 2 to 4 shown, the fixed base 10 includes a fixed bottom plate 12 and an enclosing seat body 13. The fixed bottom plate 12 can be detachably connected to the enclosing seat body 13 through structures such as bolts or buckles. Before the fixed bottom plate 12 and the enclosing seat body 13 are assembled, the fixed bottom plate 12 is fixed on the camera bracket, and the movable clamping seat 20 is placed on the side of the fixed bottom plate 12 facing away from the camera bracket. Then, the enclosing seat body 13 is connected to the fixed bottom plate 12. In this way, the assembly convenience of each component can be improved. Further, the enclosing seat body 13 is in the shape of an encircling cofferdam, and there is a notch on one side through which the movable clamping seat 20 can pass back and forth. The partition plate 11 is fixed to the inner peripheral wall of the enclosing seat body 13 by an integral molding process, thereby improving the connection strength between the partition plate 11 and the enclosing seat body 13 and reducing the record of connection breakage caused by external forces such as collision. Further, the fixed bottom plate 12, the lower part of the enclosing seat body 13, and the partition plate 11 enclose to form the movable cavity 10a2, and the upper part of the enclosing seat body 13, the partition plate 11, and the upper part of the movable clamping seat 20 enclose to form the accommodating groove 10a1.

[0042] In one embodiment, as Figures 4 to 6As shown in the figure, two stop arms 131 are convexly provided on the inner peripheral wall of the enclosing seat body 13 in the movable cavity 10a2. The two stop arms 131 are oppositely arranged and located at one end far from the push rod 30. Both of the two stop arms 131 abut against the side of the isolation plate 11 facing the movable cavity 10a2. Further, the movable clamping seat 20 is provided with a first abutting end 21 and a second abutting end 22. The first abutting end 21 and the second abutting end 22 are arranged at intervals along the moving direction of the movable clamping seat 20. Thus, when the push rod 30 moves a certain distance toward the side away from the enclosing seat body 13, the first abutting end 21 abuts against the inner peripheral wall of the enclosing seat body 13, and the second abutting end 22 abuts against the side of the stop arm 131 facing away from the push rod 30. At this time, the clamping structure enters the first assembly state where it can clamp and limit the quick-release plate.

[0043] Further, as Figure 5 shown, in an embodiment of the present utility model, the top of the movable clamping seat 20 is provided with an installation guiding portion 23. The installation guiding portion 23 extends into the accommodation groove 10a1. Thus, the bottom of the installation guiding portion 23 facing the quick-release plate can contact the quick-installation plate, so as to stop and limit the quick-installation plate in the up-and-down direction. Further, a guiding inclined surface 23a is formed on the surface of the installation guiding portion 23 facing away from the accommodation groove 10a1. Thus, when the quick-installation plate needs to be installed, the quick-installation plate can be used to squeeze the guiding inclined surface 23a, so as to drive the movable clamping seat 20 to move away from the fixed seat body 10, so that the quick-installation plate enters the profiling clamping groove 10a. Thus, the quick-installation plate can be installed without pushing the push rod 30.

[0044] In order to realize the automatic return of the movable clamping seat 20, as Figure 2 shown, the clamping structure further includes an elastic member 40. The elastic member 40 can be an elastic structure made of a spring or rubber material. A limiting channel is formed between the first abutting end 21 and the stop arm 131. The elastic member 40 is limitedly arranged in the limiting channel and is respectively connected to the first abutting end 21 and the stop arm 131. In the first assembly state, the elastic member 40 can be in the original length state. When the quick-installation plate squeezes the guiding inclined surface 23a, the movable clamping seat 20 moves away from the fixed seat body 10. During this process, the elastic member 40 is compressed. Subsequently, when the quick-installation plate enters the profiling clamping groove 10a and abuts against the isolation plate 11, at this time, the quick-installation plate no longer squeezes the guiding inclined surface 23a. The movable clamping seat 20 without driving force moves back toward the push rod 30 under the action of the elastic potential energy of the elastic member 40 until the elastic member 40 returns to the original length state. At this time, the quick-installation plate is limited and fixed by the clamping structure.

[0045] In an embodiment of the present utility model, as Figure 2As shown, the clamping structure further includes a rotating holding part 50, and the rotating holding part 50 is arranged at one end of the push rod 30 that exposes the fixed seat body 10. In this way, the rotating holding part 50 increases the contact area for the user to push the push rod 30 when needed, thereby improving the disassembly convenience.

[0046] Furthermore, as Figure 2 and Figure 7 shown, the rotating holding part 50 is rotatably connected to the push rod 30 through a bolt structure. One end of the rotating holding part 50 facing the enclosing seat body 13 protrudes with a first stop arc edge 51, and one end of the enclosing seat body 13 facing the rotating holding part 50 is provided with a stop baffle 132. The push rod 30 passes through the stop baffle 132 to connect the movable clamping seat 20; after the push rod 30 moves a certain distance towards the enclosing seat body 13, the first stop arc edge 51 is rotated along the first circumferential direction, and the first stop arc edge 51 can abut against the side of the stop baffle 132 facing away from the stop arm 131. At this time, the push rod 30 cannot continue to move towards the enclosing seat body 13. In this state, the first abutting end 21 abuts against the inner peripheral wall of the enclosing seat body 13, and the push rod 30 cannot move away from the enclosing seat body 13, so that the clamping structure enters the locked state; the rotating holding part 50 is rotated along the second circumferential direction opposite to the first circumferential direction. At this time, the first stop arc edge 51 is misaligned with the stop baffle 132, so that it can continue to move towards the enclosing seat body 13, and thus the quick-release plate can be taken out.

[0047] In order to realize the stop and limit of the first stop arc edge 51 by rotating along the first circumferential direction so that the first stop arc edge 51 can abut against the stop arm 131, as Figure 4 shown, a second stop arc edge 133 protrudes from one side of the enclosing seat body 13 facing the rotating holding part 50. The second stop arc edge 133 forms a through channel, and the stop baffle 132 is arranged at the outlet end of the limit channel; a rotating stop protrusion 134 protrudes from the inner peripheral wall of the through channel. After the first stop arc edge 51 rotates a certain angle, the rotating stop protrusion 134 can abut against the first stop arc edge 51. At this time, the first stop arc edge 51 cannot continue to rotate along the first circumferential direction, and the stop and limit of the rotation of the rotating holding part 50 are completed; further, the first stop arc edge 51 abuts against the inner peripheral wall of the limit channel. In this way, in the locked state, there will be no looseness between the first stop arc edge 51 and the limit channel.

[0048] The present invention also proposes a camera tripod head. The camera tripod head includes a clamping structure and a camera bracket. The clamping structure is detachably arranged on the camera bracket through structures such as bolts or buckles. The specific structure of the clamping structure refers to the above embodiments. Since this camera tripod head adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.
