[0032] Refer to Figure 1, A quick installation mechanism, comprising: a mounting base 100, a fastening clip 200, a control button 300, a positioning structure 500, and a fastening structure 700. The mounting base 100 is provided with a mounting cavity 150; the fastening clip 200 is movably mounted on the mounting base 100, the fastening clip 200 surrounds at least part of the mounting cavity 150, and the fastening clip 200 can move closer to or away from the center of the mounting cavity 150; the control button 300 is movably connected to the mounting base 100 and connected to the fastening clip 200; the control button 300 can slide relative to the mounting base 100 and drive the fastening clip 200 to move; the positioning structure 500 is provided on the mounting base 100, and the positioning structure 500 can prevent the relative movement between the fastening clip 200 and the control button 300; the fastening structure 700 is provided between the control button 300 and the mounting base 100. When the fastening clip 200 and the control button 300 are positioned and connected relative to the mounting base 100 through the positioning structure 500, the control button 300 can move relative to the mounting base 100 and drive the fastening clip 200 to move closer to or away from the center of the mounting cavity 150. When the quick installation plate needs to be installed, the control button 300 can be used to drive the fastening clip 200 away from the center of the mounting cavity 150. Since the mounting cavity 150 is formed by being surrounded by the fastening clip 200, when the fastening clip 200 moves away from the center of the mounting cavity 150, the mounting cavity 150 will be enlarged, so that the quick installation plate can be smoothly inserted into the mounting cavity 150. Subsequently, the fastening clip 200 can be driven by the control button 300 to move closer to the center of the mounting cavity 150, and the fastening clip 200 can cooperate with the mounting base 100 to clamp the quick installation plate, so as to directly and effectively achieve the installation and fixing effect of the quick installation plate. After the fastening clip 200 moves initially and clamps the quick installation plate in the mounting cavity 150, the fastening clip 200 can be initially fixed in position through the positioning structure 500, so that the fastening clip 200 can maintain the clamping and fixing effect on the quick installation plate. At this time, the control button 300 can be rotated, and the fastening clip 200 can be driven to move again through the fastening structure 700, so that the quick installation plate can be further effectively clamped and fixed, thus smoothly improving the stability of the quick installation plate in the mounting cavity 150, and further avoiding the problem of loosening of the quick installation plate and the photographic equipment.

[0033] In some embodiments, referring to Figure 3, the positioning structure 500 includes a positioning boss 510 provided on the control button 300, and the mounting base 100 is provided with a positioning baffle 520 and an avoidance notch 530; when the control button 300 rotates, it can drive the positioning boss 510 to rotate to at least partially coincide with the positioning baffle 520, and when the control button 300 rotates, it can drive the positioning boss 510 to rotate to coincide with the avoidance notch 530. When the positioning boss 510 rotates and coincides with the positioning baffle 520, the positioning baffle 520 will block the movement of the positioning boss 510 in the movement direction of the positioning boss 510. Therefore, the positioning boss 510 cannot continue to move, so as to directly and effectively achieve the positioning effect among the positioning boss 510, the control button 300 and the fastening clip 200. When it is necessary to drive the fastening clip 200, the positioning boss 510 can be rotated to coincide with the avoidance notch 530. At this time, the positioning boss 510 can slide in the avoidance notch 530, so that the control button 300 and the fastening clip 200 can move smoothly, and then the effect of expanding the installation cavity 150 can be effectively achieved, so as to facilitate the installation of the quick-release plate.

[0034] It can be envisaged that the positioning structure 500 can also include a plug pin, which is inserted into the control button 300 or the fastening clip 200 to achieve the positioning effect thereof. Therefore, the specific implementation manner of the positioning structure 500 is not unique, but can be adjusted according to the actual situation and is not limited herein.

[0035] In some embodiments, referring to Figure 4 , the fastening structure 700 includes a first inclined surface 710 and a second inclined surface 720. One of the first inclined surface 710 and the second inclined surface 720 is provided on the end face of the positioning boss 510, and the other of the first inclined surface 710 and the second inclined surface 720 is provided on the positioning baffle 520, and the first inclined surface 710 and the second inclined surface 720 can abut against each other. When the positioning boss 510 contacts the positioning baffle 520, relative positioning will be performed between the control button 300 and the mounting base 100, so that the fastening clip 200 initially achieves the positioning effect. At this time, the first inclined surface 710 and the second inclined surface 720 will be in a state of abutting against each other. When the control button 300 rotates, an oblique relative movement will be generated between the first inclined surface 710 and the second inclined surface 720, and it will drive the fastening clip 200 to move further, so that the effect of driving the fastening clip 200 to move closer to the center of the installation cavity 150 again can be effectively achieved, and then it is ensured that the quick-release plate can be installed more stably.

[0036] It is conceivable that the fastening structure 700 may also be composed of other components, such as a spring to push the fastening clip 200 to further move. Therefore, the specific implementation of the fastening structure 700 is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

[0037] In certain embodiments, reference Figure 5 and Figure 6 The first inclined surface 710 and the second inclined surface 720 are both spiral curved surfaces. The spiral curved surfaces enable the two to maintain a continuous and stable contact effect when they rotate relative to each other, thereby ensuring that the rotation of the control button 300 can smoothly drive the fastening clip 200.

[0038] In certain embodiments, reference Figure 3 A return spring 800 is disposed in the mounting seat 100, and at least one of the control button 300 and the fastening clip 200 is connected to the return spring 800. The return spring 800 is used to drive the fastening clip 200 to elastically approach the center of the mounting cavity 150. The return spring 800 can continuously apply an elastic force away from the center of the mounting cavity 150 to the fastening clip 200. Therefore, when the first inclined surface 710 and the second inclined surface 720 contact each other, the return spring 800 can press the first inclined surface 710 and the second inclined surface 720 relatively through the fastening clip 200, thereby ensuring that after the first inclined surface 710 and the second inclined surface 720 adjust the position of the fastening clip 200, the fastening clip 200 can stably maintain its position.

[0039] Specifically, there are two return springs 800 and they are respectively connected to two sides of the fastening clip 200 .

[0040] In certain embodiments, reference Figure 4 The sum of the outer contour curvature of the first inclined surface 710 and the outer contour curvature of the second inclined surface 720 is less than the outer contour curvature of a full circle. The difference in the size of the outer contour curvature of the first inclined surface 710 and the second inclined surface 720 enables the two to be completely staggered when staggered with each other, thereby ensuring that the positioning boss 510 and the positioning baffle 520 can be completely staggered, and further ensuring that the positioning boss 510 can smoothly move through the positioning baffle 520 when it is misaligned with the positioning baffle 520.

[0041] In certain embodiments, reference Figure 4 The positioning boss 510 is disposed on the side of the control button 300; a connecting nail 350 is disposed in the middle of the control button 300, and the positioning boss 510 is located on one side of the connecting nail 350 and surrounds the connecting nail 350. The connecting nail 350 can relatively connect the control button 300 and the fastening clip 200, thereby ensuring that the fastening clip 200 can be smoothly driven by the control button 300.

[0042] In certain embodiments, referenceFigure 3 The mounting base 100 includes a base 170 and an upper cover 130. The positioning baffle 520 is located on the upper cover 130, and the avoidance notch 530 is located on the base 170. The control knob 300 is movably installed between the base 170 and the upper cover 130. The division between the base 170 and the upper cover 130 not only enables the control knob 300 to smoothly extend into the mounting base 100 and connect with the fastening clip 200, but also makes the processing of the positioning baffle 520, the positioning boss 510, and the avoidance notch 530 more convenient, thus effectively reducing the production difficulty.

[0043] In some embodiments, referring to Figure 2 at least one of the fastening clip 200 and the mounting base 100 is provided with a limiting clip 900, and the limiting clip 900 extends towards the center of the mounting cavity 150. After the fastening clip 200 moves closer to the center of the mounting cavity 150, the limiting clip 900 can clamp and fix the quick-release plate in the mounting cavity 150, thereby further firmly clamping and fixing the quick-release plate in the mounting cavity 150 and reducing the possibility of the quick-release plate becoming loose.

[0044] Specifically, limiting clips 900 are provided at the edges of both the mounting cavity 150 and the fastening clip 200. Of course, it is also possible that only the mounting cavity 150 is provided with a limiting clip 900 or only the fastening clip 200 is provided with a limiting clip 900. The specific implementation method is not unique and can be adjusted according to the actual situation, and is not limited here.

[0045] The second aspect of the present utility model provides an embodiment of a photographic gimbal, including the above-mentioned quick-release mechanism. When the quick-release plate needs to be installed, the control knob 300 can be used to drive the fastening clip 200 away from the center of the mounting cavity 150. Since the mounting cavity 150 is formed by surrounding the fastening clip 200, when the fastening clip 200 moves away from the center of the mounting cavity 150, the mounting cavity 150 will be enlarged, so that the quick-release plate can be smoothly inserted into the mounting cavity 150. Subsequently, the fastening clip 200 can be driven by the control knob 300 to move closer to the center of the mounting cavity 150, and the fastening clip 200 cooperates with the mounting base 100 to clamp the quick-release plate, thereby directly and effectively achieving the installation and fixing effect of the quick-release plate. After the fastening clip 200 moves initially and clamps the quick-release plate in the mounting cavity 150, the fastening clip 200 can be initially fixed in position through the positioning structure 500, so that the fastening clip 200 can maintain the clamping and fixing effect on the quick-release plate. At this time, the control knob 300 can be rotated, and the fastening clip 200 can be driven to move again through the fastening structure 700, so that the quick-release plate can be further effectively clamped and fixed, thereby smoothly improving the stability of the quick-release plate in the mounting cavity 150 and avoiding the problem of loosening of the quick-release plate and the photographic equipment.

[0046] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0047] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
