Description

Technical Field

[0001] The utility model relates to the technical field of a quick-release base for assembling photographic cameras and the like, and in particular to a quick-release base for photography. Background Art

[0002] Quick-release mounts are commonly used as auxiliary equipment in photography, primarily used to connect photographic equipment to mounting brackets, enabling quick locking and unlocking of the mounting bracket. However, existing quick-release mounts rely on a locking tongue to directly control the locking of the other side. However, this approach, where the drive mechanism directly acts on the locking tongue, can significantly impact its lifespan due to long-term use of the driving force. Furthermore, these mounts can be difficult to lock, experience gaps, and exhibit poor compatibility. Utility Model Content

[0003] The utility model aims to provide a quick-release base for photography, which utilizes a driving mechanism to control the movement of a movable part, and then a lock tongue moves along the movable part, thereby reducing direct impact on the lock tongue through linkage and extending its service life.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions.

[0005] A quick-release base for photography, comprising a base and a locking mechanism movably arranged on the base to switch between a locked position and a released position, wherein a locking groove is formed on the upper surface of the base and a clamping groove is provided below the locking groove;

[0006] The locking mechanism includes a locking tongue and a movable part that are linked to each other. When the movable part moves in the clamping groove, the locking tongue is driven to move along the movable part, so that it approaches or moves away from the end of the base. While adjusting the locking groove, the locking tongue releases or locks the quick-release plate.

[0007] Furthermore, the movable part is linked to a handle, and the handle drives the lock tongue to move along a gradually changing track on the movable part during movement.

[0008] Furthermore, the lock tongue, the movable part and the handle are arranged on the same side, and the handle moves so that the lock tongue is linked with the movable part, or the lock tongue is separated from the movable part.

[0009] Furthermore, the gradual change trajectory is a trajectory that gradually changes in the height direction, and the movement trajectory of the handle is a trajectory on the same horizontal plane.

[0010] Furthermore, the movable member is provided with an inclined guide portion, and the inclined guide portion is provided with a guide groove with a gradually changing height.

[0011] Furthermore, a protrusion structure that matches the guide groove is provided at the bottom of the lock tongue.

[0012] Furthermore, the movable part includes a knob and a linkage disk fixedly connected to the knob, and the gradual track is formed on the linkage disk passing through and assembled in the clamping groove.

[0013] Furthermore, the locking tongue forms a locking cavity. When the movable part moves, the locking cavity rotates along the base and locks or releases the quick-release plate.

[0014] Furthermore, a clearance groove for accommodating the clamping groove is formed on the lock tongue, and unlocking mechanisms are connected to both sides of the clearance groove through torsion springs.

[0015] Furthermore, the base is provided with a clamping portion on a side facing the locking mechanism, and the unlocking mechanism drives the clamping portion away from the locking mechanism to achieve unlocking during unlocking.

[0016] The beneficial effects of the utility model are as follows:

[0017] In the present invention, the positional relationship between the transmission track and the camera group is utilized to achieve 360° all-round photo collection, thereby improving the accuracy of appearance recognition detection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.

[0029] Refer to the attached Figure 1-7 As shown, the quick-release mount for photography in this embodiment includes a base 100, a locking mechanism 200 movably disposed on the base 100 to switch between a locked position and a released position, and a quick-release plate 300. The quick-release plate 300 is locked in a locking groove 110 formed on the upper surface of the base 100 through the locking mechanism 200.

[0030] Unlike the prior art, this embodiment features a snap-in slot 120 on the base 100, specifically below the locking slot 110. The locking tongue 210 and movable member 220 that comprise the locking mechanism 200 are interconnected, allowing the mechanism to drive the movable member 220, while the locking tongue 210 synchronously moves on the movable member 220. This arrangement achieves linked motion, allowing the movable member 220 to move in different directions to unlock or lock. During this motion, the locking tongue moves closer to or away from the base, or up and down, driving the adjustment of the locking slot to lock or release the quick-release plate.

[0031] Compared with other locking methods in the prior art, this embodiment uses linkage to complete locking, which improves the overall efficiency. At the same time, in this embodiment, the movable part is rotated and the lock tongue moves directly along the base, so that the lock tongue faces upward, and then when locking is formed, it engages more tightly with the quick-release plate, thereby making the locking more secure and reducing the generation of virtual positions. At the same time, by subsequently converting the nut, it can also be compatible with the sizes of quick-release plates from most different manufacturers on the market, and has strong compatibility.

[0032] In this embodiment, a snap-fitting groove 120 is provided, which is subsequently matched with an A-shaped groove. The A-shaped groove is a dovetail groove, which is snap-fitted with the snap-fitting groove, thereby enabling the entire base to be limited and fixed.

[0033] In this embodiment, for ease of operation, a handle 230 is linked to the movable member 220, and then the handle 230 is operated to move, so that it drives the movable member 220 to move, driving the lock tongue 210 to move along the gradually changing track on the movable member 220. In a specific embodiment, the handle can be arc-shaped and then extend out of the base and be arranged on the side of the base 100 to facilitate operation. In this case, the gradually changing track is specifically a track that gradually changes in the horizontal direction or the height direction. The subsequent embodiments are described using a horizontal gradual change as an example. In this case, the space of the clamping slot 120 in the base 100 can be fully utilized to make the lock tongue 210 move within the clamping slot 120.

[0034] In the prior art, most of the lock tongue and the movable part are arranged on different sides, and are generally arranged relative to each other. However, in this embodiment, the space is fully utilized, and the lock tongue 210, the movable part 220 and the handle 230 are arranged on the same side. By controlling the movement of the handle 230, the lock tongue 210 is linked with the movable part, or the lock tongue is separated from the movable part. In actual use, for example, referring to the attached Figure 8 As shown, when the lock tongue 210 is fully locked, the dovetail groove subsequently formed by the entire lock tongue completes the locking after the entire lock tongue reaches the low and high points along the gradient trajectory. However, at this time, the height space required by the locking groove 110 is convenient for taking out the quick-release plate, and then the handle is continued to be rotated, so that the lock tongue is separated from the original gradient trajectory, and then the lock tongue is out of contact. When the quick-release plate is taken out, the lock tongue is driven to rotate to form an outward motion trajectory, and the dovetail groove formed by the lock tongue changes from a state close to the locking groove to a state away from the locking groove, completing complete unlocking.

[0035] The gradual change trajectory, specifically a trajectory that gradually changes in height in this embodiment, is a trajectory on the same horizontal plane. The handle 230 always moves in the same horizontal plane, such as rotating or moving horizontally back and forth. This linkage results in the locking tongue 210 moving horizontally along a trajectory that gradually changes in height, from low to high, or from high to low, achieving locking or unlocking in the process.

[0036] As shown in the accompanying drawings, to achieve gradual height change, a beveled guide portion 221 is provided on the movable member 220. The beveled guide portion 221 is provided with a guide groove that forms a gradual height change. The guide groove in this embodiment can be an arc-shaped structure, utilizing arc-shaped motion to form an arc-shaped trajectory during movement, gradually increasing and decreasing the height. Compared to a linear trajectory, this is safer and reduces wear.

[0037] To ensure stable linkage between the lock tongue and the movable member, ensuring they are always in a state of linked contact, a protrusion structure 211 is provided at the bottom of the lock tongue 210, which cooperates with the guide groove. In this embodiment, the protrusion structure 211 is always within the guide groove. When the movable member rotates, the guide groove also rotates with it, and the protrusion structure passively rotates with it, from a low position to a high position, away from the center, causing the locking groove on the base to widen, thereby achieving unlocking. During locking, the reverse rotation is made, causing it to move from a high position to a low position, and the lock tongue automatically moves closer to the center position, causing the locking groove formed above to narrow, and the quick release plate to be locked.

[0038] As shown in the accompanying drawings, the movable member 220 includes a knob 222 and a linkage disk 223 fixedly connected to the knob 222. The linkage disk 223, which passes through and is assembled in the engaging slot 120, is formed with the gradually changing track. By being arranged on a circular disk structure, it is easy to rotate and drive the adjustment of the track direction.

[0039] In this embodiment, a locking cavity is formed above the locking tongue 210, which passes through the base 100 after passing through the snap-fit ​​groove 120 and extends into the locking groove 110, and then forms a locking groove 110 with the dovetail structure on the other side of the base 100. When the movable part 220 moves, the locking cavity rotates along the base 100 and approaches the center, thereby locking or releasing the quick-release plate 300.

[0040] To achieve linkage, in this embodiment, the lock tongue 210 is connected to the engaging slot 120. A clearance slot is then formed on the lock tongue 210 to accommodate the engaging slot 120. The unlocking mechanism 400 is connected to both sides of the clearance slot via torsion springs 212. Specifically, a clamping portion 130 is provided on the side of the base 100 facing the locking mechanism 200. During unlocking, the unlocking mechanism 400 drives the clamping portion 130 away from the locking mechanism 200 to achieve unlocking. In this embodiment, the entire upper locking slot is formed by the clamping portion 130 (i.e., the dovetail structure) and the lock tongue 210 passing through the engaging slot 120. Within the engaging slot 120 below the locking slot 110, the lock tongue and the unlocking mechanism are linked, and unlocking or locking is achieved through controlled movement.

[0041] Refer to the attached Figure 1-6 As shown, in this embodiment, it specifically includes a base 100, and then two sides of the base 100 are fixed, and the other two sides are pulled through to form a locking groove 110, and then one side of the unlocking mechanism 400 is provided to form positioning, and then the other side is provided with a locking mechanism formed by a lock tongue 210, and a conversion nut 140 is provided on the base 100, for example, it can be a 3 / 8 to 1 / 4 nut, so that it has better adaptability and compatibility when assembled with a quick-release plate or other structures.

[0042] During assembly, the lock tongue 210 and unlocking mechanism 400 are positioned on either side of the conversion nut 140. The clearance groove of the lock tongue 210 precisely accommodates the assembly of the conversion nut 140. Two assembly holes are formed on one side of the torsion spring, which connect to the pin 240 that passes through the lock tongue to form the clearance groove. A spring 410 is disposed within the housing of the unlocking mechanism 400 and connects to the extension of the assembly hole of the torsion spring 212. In this embodiment, the placement of the torsion spring within the clearance groove, in conjunction with the pin, creates a torsion force that forces the lock tongue 210 to maintain an upward force, preparing for the subsequent lifting and tightening of the quick-release plate.

[0043] In this embodiment, the linkage disk 223 is assembled on the base 100 through the gasket 224. The knob controls the rotation of the movable part 220 composed of the linkage disk 223, and then the lock tongue 210 rotates accordingly through the protrusion structure 211. When locking, the rotation causes the lock tongue 210 to first move away from the conversion nut 140 and move upward. At this time, the locking cavity is formed on the lock tongue 210 by the hook. When the lock tongue moves up and down, the hook moves away from or close to the locking groove to adjust its height. When moving away, its height becomes larger, and the quick-release plate can be placed therein. In the reverse movement, the locking cavity moves toward the locking groove 110, thereby pressing and locking the quick-release plate above it; when unlocking, since the lock tongue 210 is only adjusted in height and cannot be adjusted horizontally, the unlocking is not complete. At this time, the unlocking button of the unlocking mechanism 400 can act on the spring 410, so that it acts on the torsion spring and the lock tongue 210, so that it moves horizontally away from the conversion nut to complete the unlocking process.
