[0028] See also Figures 1 to 7 The utility model relates to a locking structure, comprising a main body 1, on which a movable locking member 3 is provided, and the locking member 3 is connected to a driving assembly through a connecting member 33, and the driving assembly can move the locking member 3 through the connecting member 33, and locking can be achieved during the movement of the locking member 3; the driving assembly is provided with an actuator 2, and the actuator 2 is used to operate the driving assembly. Specifically, the main body 1 is provided with a through hole 11 for the rod body to rotate, and the locking member 3 can partially enter the through hole 11 during the movement to achieve locking of the rod body, that is, the locking member 3 is squeezed on the surface of the rod body to achieve locking.

[0029] As can be seen from the accompanying drawings, in the present application, the driving assembly includes a driven gear 22, and the actuator 2 can directly or indirectly drive the driven gear 22 to rotate; the driven gear 22 is provided with an eccentric rod 23, and one end of the connecting member 33 is assembled on the eccentric rod 23; the driven gear 22 drives the eccentric rod 23 to move during rotation, and drives the locking member 3 to move through the connecting member 33. In this structure, the connecting member 33 is driven to move by the driven gear 22 and the eccentric rod 23 thereon, which is similar to a crank-connecting rod structure, and has good continuity, that is, whether the driven gear 22 rotates forward or reversely, the unlocking or locking operation can be realized, and stepless adjustment can be realized, and the operation is convenient.

[0030] In addition, the driving assembly also includes a driving gear 21 meshing with a driven gear 22. The actuator 2 drives the driving gear 21 to rotate and drives the driven gear 22 to rotate to achieve locking or unlocking operations. The driving gear 21 and the driven gear 22 are both arranged in the assembly cavity in the main body 1, and the overall assembly structure is compact; and the driving gear 21 is provided with a driving gear bushing 211 for limiting, and the driven gear 22 is provided with a driven gear bushing 221 for limiting, which is convenient for assembly and also serves the function of limiting and supporting.

[0031] In the present application, the actuator 2 is a rotating rod, which is inserted into the assembly through hole on the driving gear 21 and can drive the driving gear 21 to rotate by rotating, which is easy to operate.

[0032] In the present application, the main body 1 is provided with a locking member assembly cavity 17, and the locking member 3 is movably arranged in the locking member assembly cavity 17; a reset spring 13 is provided between the locking member 3 and the main body 1, which is used to provide elastic force for resetting the locking member 3. The outer end of the connecting member 33 is limited on the locking member 3 by a locking nut 331 and a gasket 332, which is convenient for assembly and disassembly.

[0033] Referring to the accompanying drawings, in one embodiment of the present application, the main body 1 is provided with two through holes 11 distributed on both sides, the driving assembly is arranged between the two through holes 11, and both sides of the locking member 3 are provided with locking surfaces 38 that can extend into the through holes 11. The locking structure in this structure can be sleeved on two rods, and can complete the locking and unlocking operations of the two rods at the same time.

[0034] Moreover, in this embodiment, there are two stacked driving gears 21, there are also two driven gears 22, the eccentric rod 23 passes through the eccentric hole on the driven gear 22, and the inner end of the connecting member 33 is arranged between the two driven gears 22, which has a compact structure, good stability and high gear transmission strength.

[0035] From the above description, it can be seen that the locking structure in the present application can be put on the rod body of the tripod for use. In the unlocked state, the locking structure and the rod body can slide relative to each other. When locking is required, the actuator 2 is operated to drive the driving component to move. The driving component drives the locking member 3 to move through the connecting member 33. After movement, the locking member 3 is against the rod body to achieve locking. At this time, the locking structure and the rod body are locked and can no longer slide relative to each other. When unlocking is required, continue to operate the actuator 2.

[0036] Specifically, the working principle of the locking structure in the preferred embodiment of the present application is as follows: the two rods are respectively inserted into the through holes 11 on both sides of the main body 1. In the unlocked state, the main body 1 can slide freely on the rod. When it slides to a suitable position and needs to be locked, the actuator 2 is rotated forward or reversely to drive the driving gear 21 to rotate, and then the driven gear 22 is driven to rotate through meshing. At this time, the eccentric rod 23 on the driven gear 22 moves to pull the locking member 3 inward. During the inward movement of the locking member 3, the locking surfaces 38 on both sides of the locking member 3 enter the corresponding through holes 11 through the notch 18 and press on the surface of the rod to generate pressure to achieve the purpose of locking. At this time, the main body 1 and the rod are relatively fixed.

[0037] When unlocking is required, the actuator 2 is rotated forward or reversely, the gears mesh, the driven gear 22 rotates, the eccentric rod 23 thereon moves, and the connecting member 33 is pushed outward. At this time, the locking member 3 also moves outward under the action of the return spring 13, and the locking surface 38 moves outward to contact and lock.

[0038] Since the movement of the connecting member 33 is a swaying movement, the diameter of the hole of the locking member 3 for the connecting member 33 to pass through should be larger than the diameter of the connecting member 33 to avoid jamming.

[0039] As described above, the utility model provides a novel locking structure, which is used to be sleeved on a rod body and can be conveniently locked on the rod body and is also convenient to unlock with a strong locking force.

Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
