DETAILED DESCRIPTION

[0030] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but 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 the field based on these embodiments are all within the scope of protection of the present invention.

[0031] See attached Figure 1-7 As shown, an adjusting member unlocking assembly 1 in this embodiment includes an adjusting member 21 formed by a hook or ring structure, an adjusting member body 22 forming an assembly cavity, and a connecting member 23 placed in the adjusting member body 22, wherein the connecting member 23 partially extends out of the assembly cavity and is clamped in the cavity of the fixing member 1; in this embodiment, when the adjusting member 21 is in the set position of the assembly cavity, the connecting member 23 is locked on the fixing member 1, and when the adjusting member 21 is forced to leave the set position, the adjusting member 21 and the connecting member 23 enter the rotating slide rail of the assembly cavity, rotate the adjusting member 21, drive the connecting member 23 to rotate along the assembly cavity, so that the adjusting member body 22, the connecting member 23 and the adjusting member 21 are separated from the fixing member 1, and the unlocking is completed. In actual use, a fixed or locked position is generally set in the fixing member 1, and the fixed or locked position at this time is the set position in this embodiment, and the position can be adjusted in the fixing member 1 according to the adjustment of the application scenario, etc.

[0032] In this embodiment, the inner wall of the fixing member 1 is provided with a groove, and then a protrusion matching the groove is provided on the connecting member 23. When the adjusting member 21 in the entire adjusting member unlocking assembly is pressed, the protrusion enters a position at the same height as the groove and is dislocated, and then rotates in the horizontal direction. At this time, the protrusion rotates horizontally to enter or leave the groove, thereby achieving locking and unlocking with the fixing member 1. In this embodiment, the rotating slide rail matches the bottom of the adjusting body, and then the adjusting body rotates, driving it to rotate, and then unlocking.

[0033] In order to facilitate the connection between the adjustment body and the adjustment member, an assembly part is further provided. At this time, the assembly part enters the adjustment member body and is connected to the adjustment member, and then a cover plate 26 is provided on the upper part to realize the top limit of the assembly part. In this embodiment, the assembly part can be a screw, a step shaft riveting or a gluing, so as to complete the preliminary connection between the adjustment body and the adjustment member.

[0034] In this embodiment, in order to ensure the connection of the adjusting member body 22, a moving track is formed in the adjusting member body, and the moving track extends inward to form a bearing platform 221 of the connecting member 25. Therefore, when the connecting member 25 moves in the vertical direction, it has a certain bearing and force-bearing surface.

[0035] After the assembly parts such as screws are connected to the adjustment part 26, there is a certain gravity. At this time, the inner wall of the connection part 23 extends inward to form a bearing ring of the screw nut (i.e., the assembly part head). When the adjustment part 26 is pressed, it will move upward. At this time, the assembly parts in the adjustment part body connected to it will move upward away from the bearing ring 231, and the cover plate will have a good limiting effect at this time. In order to achieve the later reset, in this embodiment, the reset component 25 is sleeved on the screw rod of the screw. After the pressing and rotation are completed, the reset component 25 is compressed, the pressing force is released, and the reset component 25 is reset, so that the entire adjustment part, the adjustment body and the connection parts move downward and separate from the fixing part.

[0036] In this embodiment, the adjusting member 21 specifically includes three parts, the upper part of the adjusting member, the lower part of the adjusting member and a connecting plate connecting the two. After pressing, the connecting plate specifically enters into the rotating slide rail formed under the adjusting member body 22, providing a basis for subsequent use.

[0037] Specifically, an assembly portion with a receiving cavity is formed on the upper part of the adjusting member, and a slider 261 is formed on the periphery of the assembly portion. When the connecting plate enters into the rotating slide rail, the slider moves along the vertical slide rail in the connecting member or the adjusting member body. Since there will be a certain vertical movement during pressing and resetting, vertical slide rails (not shown in the figure) for the adjusting member 21 to move up and down are formed in the connecting member 23 and the adjusting member body 22. In this embodiment, the vertical slide rail in the adjusting member body is set to restrict the connecting member from rotating. At this time, the slider of the adjusting member is on both the slide rail of the adjusting member and the slide rail of the connecting member, and then the rotation of the connecting member is restricted by restricting the adjusting member from rotating. Once a possible vertical movement occurs, the adjusting member 21 moves along the vertical slide rail in the connecting member 23, and the connecting member moves along the vertical slide rail in the adjusting member body 22. In this embodiment, the purpose of the vertical slide rail is to prevent the connecting part from rotating when the assembly cavity is not subjected to force. The connecting part is provided with upper and lower vertical slide rails, and its function is to ensure that when a vertical left and right force is applied to the adjusting part, the adjusting part can move up and down on the connecting part, and when a rotational force is applied, it drives the connecting part to rotate.

[0038] In order to facilitate entry into the rotating slide rail, a step-shaped structure 222 is extended outward from below the assembly cavity on the adjusting member body 22, and the rotating slide rail is formed inside the step-shaped structure.

[0039] In this embodiment, when the adjusting member body 22 and the connecting member 23 are assembled, a locking cavity 223 is provided at a set position on the inner wall of the assembly cavity of the adjusting member body 22, and a matching locking block 232 is provided on the outer side of the connecting member 23. In addition, during rotation, the locking cavity 223 and the locking block 232 can be locked and unlocked, and during pressing force, only the assembly part 24 and the adjusting member 21 can move up and down in the adjusting member body 22 and the connecting member 23 synchronously.

[0040] See attached Figure 6-7 As shown, the photographic tripod in this embodiment includes the adjusting member unlocking assembly 2 in this embodiment and the fixing member 1 formed by the central axis, and the adjusting member unlocking assembly 2 is snap-fitted and assembled on the inner wall of the central axis. Specifically, the inner wall of the central axis 1 is provided with a snap-fitting groove 11 at a set position that needs to be fixed and locked, and then the adjusting member body 23 forms a snap-fitting portion 233, which is matched with the snap-fitting groove 11 to complete the snap-fitting, and the connecting member 23 is suspended in the entire structure by relying on the adjusting member body 22.

[0041] During use, when it is necessary to lock with the central axis, the adjusting member 21 is pressed, so that the adjusting member 21 and the assembly member 24 move upward in the central axis, and then the adjusting member 21 rotates to drive the snap-fitting part out of the snap-fitting groove, completing the unlocking, and then the reset assembly is reset to return to normal; when locking, it only needs to be rotated in the opposite direction to the fixed position. At this time, due to the previous reset, there is no need to press, that is, the snap-fitting part enters the snap-fitting groove by rotation to complete the locking.
