Description

Technical Field

[0001] The utility model relates to a buckle structure of a tripod. Background Art

[0002] According to market research and patent searches, the quick-locking and quick-retracting self-locking support rods of existing tripods are generally driven by connecting the two ends of a rotating shaft. For example, the Chinese invention patent application publication number CN116006636A discloses a quick-retracting self-locking support rod that is smoothly driven by a worm gear combination gear, including a support platform for placing photographic equipment, a mounting seat connected to the support platform, a drive shaft arranged in the mounting seat, a swing handle connected to the drive shaft, and a drive gear connected to the drive shaft; the drive gear engages with a driven gear, and the driven gear drives the worm gear mechanism to drive the telescopic rod to perform a telescopic action and form a self-locking action; the driven gear is arranged on the worm shaft, the mounting seat provides an axis groove for the shaft neck installation of the worm shaft, and the worm shaft is connected to the telescopic operating rod; the mounting seat provides an axis hole for the worm shaft to be installed perpendicularly to the worm shaft. Its operation transmission is smooth and noiseless. The worm teeth are continuous and uninterrupted spiral teeth, and the meshing is continuous. There is no process of the worm teeth entering and exiting the meshing, and the worm wheel is only driven by the worm wheel. The anti-worm wheel self-reverse drive realizes self-locking, and can achieve rapid extension and self-locking. The gear meshing transmission forms a motion compensation margin, which makes the coordination smooth and avoids the phenomenon of tooth jamming. However, the swing handle operation requires a larger space, so the product design and operation are not so compact and flexible. In order to overcome the above defects, we have comprehensively optimized the original structure and developed a tripod buckle structure. Utility Model Content

[0019] The following further describes the specific embodiments of the present invention in conjunction with the drawings in the specification, so as to make the technical solutions and beneficial effects of the present invention clearer and more specific; and is intended to explain the present invention but should not be understood as limiting the present invention.

[0020] Reference Figure 1-3 As shown, the embodiment of the present invention preferably provides a tripod trigger structure, which includes a telescopic leg 1 and a support part 2 connected to the upper part of the telescopic leg. The telescopic leg has a pipe joint part 3, and the pipe joint part 3 and the support part 2 are switched between a mutually abutting and locked state and a mutually disengaged and unlocked state by means of a trigger structure 4. The telescopic leg 1 is multi-sectioned and can be slidably moved and retracted relative to the pipe joint part 3; the trigger structure 4 includes an operating handle 5, and the operating handle 5 has a propulsion member 51; the propulsion member 51 drives the locking and releasing device 6 of the telescopic leg 1, so that the telescopic leg is controlled by the operating handle 5 to lock or release the free telescopic movement when it reaches the appropriate length during telescoping.

[0021] The operating handle 5 is pivotally attached to the pipe joint part 3 and can be in a closed, close position (e.g. Figure 1 The position of the operating handle 5 shown in FIG) and the open flip-up position (as shown in FIG) Figure 2 The operating handle 5 is pivotally moved between the positions shown in FIG.

[0022] The pipe joint portion 3 is configured with an opening 31 to form protruding arms 32 and 33 on both sides, wherein the pushing member 51 is accommodated in the opening and moves in a space between the protruding arms 32 and 33 on both sides.

[0023] In one or more embodiments of the present invention, the two side convex arms 32, 33 are provided as the bottom surface of the holding end 52 of the operating handle 51, and the bottom surface forms an arc-shaped convex surface 34. Such an arc-shaped convex surface makes operation smoother and prevents jamming.

[0024] The opening 51 is located outside and in the middle of the pipe joint part 3, so the space is reasonably utilized, the structure is more space-saving, and the compactness is good.

[0025] The locking and releasing device 6 includes a worm gear mechanism, and the specific structure can be Chinese invention patent CN116006636A, which discloses a worm gear drive mechanism in a self-locking support rod that is rapidly retracted and smoothly driven by a worm gear combination gear. It can also be other structural methods that can lock and release the telescopic rod.

[0026] When in use, when the telescopic rod reaches a suitable length, the operating handle 5 is pressed downwards, as shown in FIG. Figure 1 In the closed, snug position shown in the figure, the telescopic rod is locked and the support 2 is securely secured. To unlock, the telescopic rod is released by flipping the handle 5 in the opposite direction, thus freeing up the telescopic rod for telescopic movement. This saves time and steps, making it particularly suitable for scenes requiring quick adjustment of shooting angle and height, such as outdoor snapshots or sports photography. It effectively reduces shaking caused by improper manual adjustment or loose locking, improving film quality and making the tripod more compact and lightweight for angle adjustment and storage. It offers superior performance in terms of technology, economy, and practicality.

Therefore, it is intended that the appended claims be interpreted as including all such variations, substitutions, and equivalents that fall within the true spirit and scope of the present invention. Those skilled in the art should understand that the present invention is not limited to the specific embodiments described above, and that improvements and substitutions based on the present invention using known techniques in the art fall within the scope of protection of the present invention and should be defined by the claims.
