Description

Technical Field

[0001] The utility model belongs to the technical field of photographic equipment, and particularly relates to a quick-release plate for a photographic device that can be folded and stored and has an adjustable angle. Background Art

[0002] A photographic quick-release plate is one of the most widely used photographic devices. This photographic quick-release plate is used to quickly mount a camera on the quick-release clamp of a tripod or a pan-tilt head.

[0003] In order to be able to mount a camera horizontally and vertically at the same time, an L-shaped quick-release plate has emerged on the market. These L-shaped quick-release plates are composed of a horizontal plate and a vertical plate, and have an L-shaped structure. For example, a photographic quick-release plate of ZL202123008087.1. However, the applicant found that this patent needs to fix the horizontal plate and the vertical plate by screwing screws. Such a structure not only cannot be folded and stored, but is also relatively cumbersome for installation and disassembly, and the angle can only be fixed at 90°, which cannot meet the photographic needs required at more angles, and there are problems with limited practicality.

[0004] Therefore, the applicant has developed and provided a quick-release plate for a photographic device that can be folded and stored. While having a cavity and holes for basic auxiliary installation, it can achieve angle adjustment and folding storage. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems raised in the background art, and a quick-release plate for a photographic device that can be folded and stored and has an adjustable angle is designed.

[0006] To achieve the above object, the technical solution of the utility model is as follows: A quick-release plate for a photographic device that can be folded and stored and has an adjustable angle, including a vertical plate and a horizontal plate, characterized in that the vertical plate and the horizontal plate are movably connected by a ball screw; a fixing through hole is provided on the horizontal plate for the ball screw to be inserted; and a plurality of curved cavities are formed on the vertical plate in a circular array to cooperate with the ball screw for positioning and fixing.

[0007] Preferably, the fixing through holes on the horizontal plate are symmetrically designed, with a total of two groups, each group containing three fixing through holes, and all are formed on the same horizontal line.

[0008] Preferably, at the center of a circle of cavities formed on the vertical plate in a circular array, a positioning middle hole with the same diameter as the cavity is provided.

[0009] Preferably, the fixing through hole is an internal thread through hole.

[0010] Preferably, the ball screw is composed of a spring, a steel ball, and a housing. An external thread is formed on the outer wall of the housing to be threadedly connected and fixed with the fixing through hole, and the steel ball falls into the cavity and the positioning middle hole to cooperate with them.

[0011] Preferably, the transverse plate is designed and formed with an anti-skid groove, a track groove, an arc groove, an auxiliary positioning screw hole and a first clamping groove.

[0012] Preferably, the vertical plate is designed and formed with a second snap-fitting groove, an empty groove and a plurality of auxiliary positioning screw holes.

[0013] Preferably, the anti-skid groove is designed as a sunken cavity for the installation of the anti-skid gasket.

[0014] Compared with the prior art, the advantages of the present invention are: the present invention adopts glass bead screws to replace the limit pieces or ordinary connecting screws mentioned in the prior art. Compared with the prior art, the limit pieces or ordinary connecting screws can only be limited after connection and fixation to allow the vertical plate to move left and right, and after assembly, they occupy more space as an L-shaped structure during storage. The present invention is designed to form a groove cavity with a curved surface design to match the glass bead screw. When the glass bead screw is subjected to a force exceeding the maximum force, its steel ball will be compressed into the shell to allow the user to adjust the angle clockwise or counterclockwise or fold it for storage. When the photographic equipment is fixed normally and the maximum force is not exceeded, the steel ball of the glass bead screw will be firmly positioned in the groove cavity. In addition, there are two groups of fixing through holes for the glass bead screw, so the weight of the equipment it can withstand will be significantly improved, and it will not easily slide, fall out, shake, etc., thereby significantly improving the stability of the fixed photographic equipment.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4As shown in the figure, the utility model is a quick-release plate for a photographic device that can be folded and stored and has its angle adjusted. The utility model mainly consists of two parts, namely a vertical plate 1 and a horizontal plate 2, and a ball plunger screw composed of a spring, a steel ball, and a housing. The vertical plate 1 and the horizontal plate 2 are movably connected by the ball plunger screw. Thanks to the structural design of the ball plunger screw, the utility model can be folded and stored for easy storage, and at the same time, the photographic angle can be adjusted in gears according to requirements. The folding and gear adjustment are specifically that a plurality of curved groove cavities 10 formed in a circular array on the vertical plate 1 cooperate with the ball plunger screw for positioning and clamping or retracting displacement after compression. Because when the ball plunger screw is subjected to a force exceeding the maximum force, its steel ball will be compressed into the housing, and the curved groove cavity 10 at this time can better cooperate with the similarly curved steel ball to assist it in retracting. The user can then rotate clockwise or counterclockwise according to requirements to make the ball plunger screw fall into the next or previous groove cavity 10 in the circumferential direction, thus completing the required gear adjustment or folding. In this regard, a fixing through hole 20 is provided on the horizontal plate 2 for the ball plunger screw to be inserted. However, the fixing through holes 20 on the horizontal plate 2 are symmetrically designed, with a total of two groups, each group containing three fixing through holes 20, and all are formed on the same horizontal line. Among them, the left and right fixing through holes 20 in each group are used for the active actions of gear adjustment or folding, while the middle fixing through hole 20 serves as a central axis, which cooperates with the positioning middle hole 11 on the vertical plate 1 to play a role in positioning, centering, and limiting the connection and assembly of the vertical plate 1 and the horizontal plate 2. It can be further explained that the fixing through hole 20 is an internal thread through hole, and the outer wall of the housing of the ball plunger screw is formed with an external thread to be threadedly connected and fixed with the fixing through hole 20.

[0021] Among them, anti-slip grooves 21 are designed and formed on the horizontal plate 2 for the installation of anti-slip gaskets, track grooves 22 are designed and formed for the linear position adjustment of connecting screws to meet the connection and fixation of photographic equipment of different sizes on the horizontal plate 2, arc grooves 23 are designed and formed to be fixed after the photographic angle is adjusted, and auxiliary installation positioning screw holes 30 and first clamping grooves 24 are also designed and formed to meet the positioning and assembly of more different specifications of photographic equipment. Similarly, second clamping grooves 12, empty grooves 13, and a plurality of auxiliary installation positioning screw holes 30 are designed and formed on the vertical plate 1, which can be used as wire passing holes, wire grooves, or lens picture clearance, bringing more flexible and variable use.
