In addition, the terms: first, second, etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features shown. In the description of the present utility model, unless otherwise clearly specified and limited, the terms: install, connect, connect, etc. should be understood in a broad sense, and ordinary technicians in this field can understand the specific meanings of the above terms in this application according to the specific circumstances.

[0027] See also Figures 1 to 10 The utility model relates to a compact rotating locking and disassembly device, comprising a main body 11, a lifting rod 5 passing through the main body 11 and movable up and down; an assembly platform 19 is provided on the upper part of the main body 11, and a rotating member 4 that can rotate relative to the assembly platform 19 is provided on the outside of the assembly platform 19; an assembly platform through hole 16 is provided on the assembly platform 19 for the lifting rod 5 to pass through, and a plurality of assembly stations 15 are provided on the periphery of the assembly platform through hole 16, and a movable locking block 6 is provided in the assembly station 15; a guide structure composed of a guide column 62 and a guide slot 43 is provided between the rotating member 4 and the locking block 6, and during the rotation of the rotating member 4 relative to the assembly platform 19, the guide structure causes a plurality of the locking blocks 6 to expand or retract synchronously; when a plurality of the locking blocks 6 are synchronously expanded, the lifting rod 5 is released from locking, and when a plurality of the locking blocks 6 are synchronously retracted, the lifting rod 5 is locked.

[0028] From the attached Figure 4 It can be seen that in the present application, the locking block 6 is provided with an elastic member 64, and the elastic force of the elastic member 64 causes the locking blocks 6 to be retracted or have a tendency to be retracted. The inner surface of the locking block 6 is provided with a locking surface 61, and when the locking blocks 6 are retracted, the locking surface 61 presses on the lifting rod 5 to lock the lifting rod.

[0029] In this application, a housing 1 is sleeved outside the main body 11, and anti-slip convex surfaces 49 and concave surfaces 491 are alternately arranged on the outer surface of the rotating member 4, which is convenient for hand-held operation. In the embodiments shown in the attached drawings of this application, there are three locking blocks 6 evenly distributed axially, and there are also three matching assembly stations 15; bolt perforations 14 are provided at positions between adjacent two assembly stations 15. The structure is compact, the locking effect is good, the strength is high, and the parts are easy to process. Of course, it is a feasible technical solution to set 2 - 5 locking blocks 6, and corresponding functions can be achieved.

[0030] It can also be seen from the attached drawings that in this application, a partition 41 is provided in the rotating member 4, the guiding chute 43 is arranged on the partition 41, and the guiding columns 62 protruding upward on the locking block 6 extend into the guiding chute 43. The guiding columns 62 can slide in the guiding chute 43 to realize the movement of the locking block 6 in the assembly station 15 for locking or unlocking operations.

[0031] Specifically, in this application, the partition 41 divides the space in the rotating member 4 into an upper cavity and a lower cavity. The assembly table 19 is assembled in the lower cavity, a positioning member 7 is assembled in the upper cavity, and a central hole 73 for the lifting rod 5 to pass through is provided on the positioning member 7. After the positioning member 7 is assembled, the positioning between the positioning member 7 and the assembly table 19 is realized, the assembly structure is carried out, the internal space is saved, and the strength is high after the positioning member 7 and the assembly table 19 are fixed to each other. At this time, only the rotating member 4 can rotate and drive the locking member 6 to move, and the overall structure is compact.

[0032] In addition, in this application, bolt perforations 14 are provided on the rotating member 4, bolt holes are provided on the positioning member 7, and positioning bolts 71 are assembled in the bolt holes after passing through the bolt perforations 14, which is convenient for installation and disassembly.

[0033] In this application, a convex column 72 protruding downward is provided on the positioning member 7, a hollow portion 42 for accommodating the convex column 72 is provided on the partition 41, and the side wall of the hollow portion 42 will contact the convex column 72 when the rotating member 4 rotates, so as to realize the limit of the rotation angle of the rotating member 4 and avoid excessive rotation. When excessive rotation occurs, the limiting function will be generated on the guiding structure. When the force is large, the guiding structure may be damaged, such as the guiding column 62 being broken. At this time, the core function of this device will be damaged, resulting in the locking function not being realized. Therefore, in this structure, the rotation angle is limited by the convex column 72 and the hollow portion 42, which can well avoid damage to the guiding structure and improve the service life. At the same time, in order to improve the part integration, the bolt hole is arranged on the convex column 72 to streamline the structure.

[0034] As can be seen from the above description, the rotary locking and disassembling device in this application can be applied to a tripod, and its working principle is as follows.

[0035] Under normal circumstances, without external force, the three locking blocks 6 approach each other under the elastic force of the elastic member 64 to lock the lifting rod 5. At this time, the lifting rod 5 is locked, and a photographic or video equipment can be installed on the mounting platform 3 on the lifting rod 5 for photography or video recording. The mounting platform 3 is arranged on the middle seat 2, and the middle seat 2 is used to install the support feet and is used as a tripod.

[0036] (2) When it is necessary to put it away or adjust the height of the mounting platform 3, the rotating member 4 thereon can be rotated, and the locking block 6 is driven by the guiding structure to move against the elastic force of the elastic member 64. At this time, the locking of the lifting rod 5 is released, and the mounting platform 3 can be moved up and down to adjust the height, or it can fall under the action of gravity and can be quickly put away for storage. The operation is convenient. After releasing the hand, the three locking blocks 6 can lock the lifting rod 5 again and will not fall off randomly.

[0037] As described above, the rotary locking and disassembling device in the present invention can be used in photographic and video equipment such as tripods. Through rotary operation, the locking and unlocking operations can be quickly realized, the purpose of locking and disassembling can be achieved, the operation is convenient, and at the same time, the structure is compact and the assembly strength is high.

[0038] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is subject to the claims. Any replacement, deformation, and improvement that are easily conceivable by those skilled in the art to this technology fall within the protection scope of the present invention.
