[0001] This utility model relates to the field of photographic equipment technology, and in particular to an anti-deflection quick-release plate structure and photographic equipment. Background Technology
[0002] In photography, gimbals are frequently used to secure cameras. A gimbal typically includes a mounting base and a quick-release plate that slides onto the mounting base. The quick-release plate and mounting base are locked together by a locking mechanism. The quick-release plate has a fastening screw for connecting the camera. This screw passes along the thickness of the quick-release plate, with its head abutting against one side of the plate and its shank passing through the other side and threaded onto the camera. When tightened, the camera and the head of the screw together clamp the quick-release plate, using friction to prevent the entire assembly of the camera and screw from deflecting relative to the plate. This stabilizes the camera's angle and position, ensuring reliable photography and videography.
[0003] However, in actual use, the friction between the head of the fastening screw and the quick-release plate is small, and the fastening screw is prone to rotating relative to the quick-release plate, which causes the camera to deflect and loosen relative to the quick-release plate, affecting the stability of photography and videography.

[0028] See Figure 1 and Figure 2 An anti-deflection quick-release plate structure according to an embodiment of the present invention includes: a quick-release plate 100, wherein a fastening screw 200 is provided through the middle of the quick-release plate 100 along its thickness direction, the fastening screw 200 is rotatable relative to the quick-release plate 100 about its axial direction, the head of the fastening screw 200 faces the lower surface of the quick-release plate 100, and the threaded shank 230 of the fastening screw 200 extends out of the upper surface of the quick-release plate 100 for connecting photographic equipment, and the quick-release plate 100 is provided with a positioning anti-deflection mechanism for preventing the fastening screw 200 from rotating relative to it.
[0029] When the camera device is threaded into the threaded rod 230, the camera device and the head of the fastening screw 200 together clamp the quick-release plate 100. The positioning anti-rotation mechanism contacts the fastening screw 200 to prevent the fastening screw 200 from rotating relative to the quick-release plate 100, thereby increasing the locking force between the fastening screw 200 and the quick-release plate 100, preventing the camera device from deflecting or loosening relative to the quick-release plate 100, and thus ensuring the stability of the photography and videography work.
[0030] See Figure 2In some embodiments of this utility model, the positioning anti-rotation mechanism is a tightening screw 300 threadedly connected to the quick-release plate 100. The tightening screw 300 can tighten the fastening screw 200 to prevent the fastening screw 200 from rotating relative to the quick-release plate 100. It should be noted that after the feed movement, the tightening screw 300 is fixed relative to the quick-release plate 100. The tightening screw 300 can be tightened at different positions on the fastening screw 200 to prevent the tightening screw 300 from rotating, thus positioning and fixing the fastening screw 200 in a very simple and low-cost manner. In this embodiment, the quick-release plate 100 is made of aluminum alloy, and a stainless steel threaded sleeve that mates with the tightening screw 300 is built into the quick-release plate 100. The stainless steel threaded sleeve has good durability.
[0031] See Figure 2 In some embodiments of this utility model, the tightening screw 300 is arranged parallel to the fastening screw 200, and the head of the tightening screw 300 abuts upward against the head of the fastening screw 200 to increase the friction between the head of the fastening screw 200 and the lower surface of the quick-release plate 100. It is understood that the tightening screw 300 is also arranged along the thickness direction of the quick-release plate 100, and will not protrude beyond the contour edge of the quick-release plate 100 to avoid interfering with the installation of the quick-release plate 100. The threaded locking force is used to increase the pressure of the head of the fastening screw 200 against the lower surface of the quick-release plate 100, thereby increasing the friction to prevent the fastening screw 200 from deflecting relative to the quick-release plate 100. Of course, in other embodiments, the tightening screw 300 can also be arranged horizontally, in which case the side wall of the quick-release plate 100 is provided with a corresponding through hole, and the end of the tightening screw 300 abuts against the shank of the fastening screw 200.
[0032] See Figure 2 In some embodiments of this utility model, the head of the fastening screw 200 is a first cylindrical portion 210, and the outer peripheral wall of the first cylindrical portion 210 is formed with a first frustum portion 220 that is smaller at the bottom and larger at the top. The head of the tightening screw 300 has a second frustum portion 310 that is smaller at the top and larger at the bottom, opposite to the first frustum portion 220. The outer peripheral wall of the second frustum portion 310 abuts against the outer peripheral wall of the first frustum portion 220 so that the upper surface of the first frustum portion 220 is pressed against the lower surface of the quick-release plate 100. It should be noted that the provision of the first frustum portion 220 increases the contact area between the head of the fastening screw 200 and the quick-release plate 100. The first frustum portion 220 and the second frustum portion 310 cooperate to increase the contact area between the tightening screw 300 and the fastening screw 200, ensuring that the tightening force can be transmitted stably and reliably.
[0033] See Figure 2In some embodiments of this utility model, the quick-release plate 100 has a generally rectangular outline, and at least two side edges of the quick-release plate 100 form a slide rail portion 110. The lower end of the quick-release plate 100 has a flat, downward-opening receiving groove 120. The heads of the fastening screw 200 and the head of the tightening screw 300 are both located within the receiving groove 120, so that the heads of the fastening screw 200 and the head of the tightening screw 300 do not protrude downward from the quick-release plate 100, and the normal assembly and disassembly of the quick-release plate 100 are not affected.
[0034] See Figure 3 In some embodiments of this utility model, a mounting base 400 is also included. The mounting base 400 is provided with a sliding mounting groove 410 that cooperates with the slide rail portion 110. The bottom wall of the sliding mounting groove 410 is provided with a locking block 500 that extends and retracts towards the slide rail portion 110 in the vertical direction. The locking block 500 is connected to an elastic member 600 that drives it to extend upward and an operating part that drives it to retract downward. The bottom of the slide rail portion 110 is provided with a slot 111 that cooperates with the locking block 500. It should be noted that the mounting base 400 is generally connected to the ball joint of the camera head to realize universal angle adjustment. The quick-release plate 100 is pre-connected to the camera equipment. Quick-release assembly is achieved by the cooperation of the slide rail portion 110 and the sliding mounting groove 410. When the locking block 500 is aligned with the slot 111, it is locked under the action of the elastic member 600. When unlocking is required, the operating part is used to drive the locking block 500 to retract and disengage from the slot 111.
[0035] See Figure 2 In some embodiments of this utility model, a through hole is provided in the center of the quick-release plate 100, and an internal threaded hole 130 is provided on the inner periphery of the through hole to cooperate with the threaded rod portion 230. A smooth rod portion 240 matching the length of the internal threaded hole 130 is provided between the head of the fastening screw 200 and the threaded rod portion 230. The above structure not only enables the fastening screw 200 to rotate relative to the quick-release plate 100 to slightly adjust the angle of the photographic equipment, but also restricts the fastening screw 200 from moving along its axial direction relative to the quick-release plate 100, thereby improving stability.
[0036] See Figure 1 In some embodiments of this utility model, a plastic washer 140 is provided protruding from the upper surface of the quick-release plate 100, located on the outer periphery of the fastening screw 200. The upper surface of the plastic washer 140 is provided with an anti-slip texture. When the photographic equipment is connected to the threaded rod 230, the photographic equipment abuts against the anti-slip texture of the plastic washer 140 under the pulling force of the fastening screw 200, thereby increasing the friction and preventing the photographic equipment from falling.
[0037] See Figure 1In some embodiments of this utility model, the quick-release plate 100 has a roughly rectangular outline. To further improve safety and prevent the photographic equipment from accidentally falling off, safety rope holes 150 are provided through the four corners of the quick-release plate 100.
[0038] This utility model also discloses a photographic device including an anti-deflection quick-release plate structure of any of the above-mentioned technical solutions. This photographic device utilizes a positioning anti-deflection mechanism to contact the fastening screw 200 and prevent the fastening screw 200 from rotating relative to the quick-release plate 100, thereby increasing the locking force between the fastening screw 200 and the quick-release plate 100, preventing the photographic device from deflecting or loosening relative to the quick-release plate 100, and thus ensuring the stability of photographic and video recording operations.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.
[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
