[0031] Please refer to Figure 1 to Figure 4 An embodiment of the utility model provides a convenient locking tripod, which includes: a connecting base 1, three supporting legs 2 and three universal joints 3. The connecting base 1 is provided with a first gear member 11 and three second gear members 12, and the three second gear members 12 are all meshed with the first gear member 11. Each supporting leg 2 is provided with a locking transmission shaft 21, and the locking transmission shaft 21 can be used to drive the locking structure inside the supporting leg 2 to achieve locking and limit the extension and retraction of the supporting leg 2, or to achieve unlocking so that the supporting leg 2 can be extended and retracted. Each universal joint 3 is connected with a second gear member 12 and a locking transmission shaft 21, which can be used to transmit the rotation of the first gear member 11 to the locking transmission shaft 21, and the universal joint 3 is arranged for linkage, so that the angle of each supporting leg 2 can be opened and retracted to a certain extent.

[0032] In this embodiment, the three second gear members 12 can be driven to rotate by rotating the first gear member 11, and the locking transmission shafts 21 in the three supporting legs 2 can be driven to rotate through the universal joint 3, thereby driving the telescopic locking or unlocking of the locking structure in the supporting leg 2. The user only needs to rotate the first gear member 11 to simultaneously control the telescopic locking and unlocking of each supporting leg 2, which is convenient and efficient to operate.

[0033] In a preferred embodiment, reference may be made to Figure 4 , three second gear members 12 are distributed circumferentially on the connecting base 1, and the inner periphery of the first gear member 11 is meshed with each second gear member 12. In this embodiment, the user can touch the outer periphery of the first gear member 11 and rotate it, thereby conveniently controlling the telescopic locking and unlocking of each supporting leg 2.

[0034] Of course, in other embodiments, the first gear member 11 may also be arranged between the three second gear members 12, wherein the outer periphery of the first gear member 11 is meshed with each second gear member 12, and may also drive the three second gear members 12 to rotate at the same time. Since the first gear member 11 is located in the middle position, in order to facilitate the rotation of the second gear member 12, a corresponding motor device may also be provided or the first gear member 11 may be manually driven.

[0035] In a specific embodiment, when the user operates the telescopic locking and unlocking of the support leg 2 , the user can directly rotate the outer periphery of the first gear member 11 .

[0036] In a preferred embodiment, in order to facilitate the user to rotate the first gear member 11, a toggle member 111 is further provided on the outer periphery of the first gear member 11. Figure 1 and Figure 4 There are preferably three toggle members 111, which are evenly distributed along the circumference of the first gear member 11. The toggle member 111 can be a protruding structure arranged on the outer circumference of the first gear member 11, or a rod-shaped structure. Of course, the toggle member 111 can also be some other shape structure suitable for user to toggle.

[0037] In some embodiments, an electric device may also be provided on the connection base 1, so that the user can drive the toggle member 111, thereby conveniently rotating the first gear member 11. In a preferred embodiment, the bottom of each second gear member 12 includes a gear transmission shaft 13, which can rotate synchronously with the second gear member 12, and each universal joint 3 is connected to a gear transmission shaft 13 and a locking transmission shaft 21. The gear transmission shaft 13 and the second gear member 12 may be integrally arranged or fixed.

[0038] Of course, in other embodiments, the second gear member 12 may not include the gear transmission shaft 13 , that is, the second gear member 12 is only a gear structure, and the universal joint 3 can directly link the second gear member 12 and the locking transmission shaft 21 .

[0039] In a preferred embodiment, reference may be made to Figure 3 and Figure 4 A mounting platform 14 is provided on the top of the connecting seat 1, and the first gear member 11 is located on the outer periphery of the mounting platform 14. Preferably, the mounting platform 14 can be substantially a truncated cone structure.

[0040] In a preferred embodiment, reference may be made to Figure 3 and Figure 4 The mounting platform 14 is further provided with a mounting groove 141 for accommodating the second gear member 12, and a through hole 142 communicating with the mounting groove 141 for passing the gear transmission shaft 13. The side wall of the mounting platform 14 has an opening at each mounting groove 141, so that the second gear member 12 extends out of the mounting groove 141 and the side wall of the mounting platform 14, so that the second gear member 12 can mesh with the first gear member 11.

[0041] In a preferred embodiment, a limiting plate 15 is also fixed on the top of the mounting platform 14, and the first gear member 11 is provided with a toothed ring 112 meshing with the second gear member 12, and a limiting ring 113 located on the outer periphery of the toothed ring 112 and extending toward the top. The limiting plate 15 is attached to the inner periphery of the limiting ring 113 and to the top of the toothed ring 112. In this embodiment, the limiting plate 15 can limit the first gear member 11 in the axial direction and in each radial direction, so that the first gear member 11 will not move toward the top and leave the mounting platform 14, and can keep the first gear member 11 and the second gear member 12 in a stable meshing state.

[0042] In a preferred embodiment, a receiving groove 143 is further provided in the middle of the mounting platform 14, and a connecting member 16 is further provided in the middle of the limiting plate 15. The connecting member 16 passes through the limiting plate 15, and one end of the head of the connecting member 16 is received in the receiving groove 143, and one end of the tail of the connecting member 16 is provided with an external thread. The external thread provided at the tail of the connecting member 16 can facilitate the installation of external camera equipment.

[0043] In a preferred embodiment, the support leg 2 is further provided with a first tube body 22 and an expansion locking assembly. The expansion locking assembly is provided on the outer periphery of the locking transmission shaft 21 and is located on the inner periphery of the first tube body 22 .

[0044] In this embodiment, when the expansion and locking assembly expands, the friction between the assembly and the first tube body 22 is increased to achieve locking. The locking transmission shaft 21 can drive the expansion and locking assembly to expand and lock the first tube body 22, or drive the expansion and locking assembly to contract and unlock the first tube body 22.

[0045] Furthermore, the expansion locking assembly includes an inner support member 23 and an expansion member 24 threadedly connected to the inner support member 23. The inner support member 23 is circumferentially fixed to the locking transmission shaft 21 so that the inner support member 23 and the locking transmission shaft 21 can rotate synchronously. The expansion member 24 is circumferentially fixed to the first tube body 22 so that the expansion member 24 and the first tube body 22 cannot rotate relative to each other.

[0046] In this embodiment, reference may be made to Figure 3 The outer diameter of the inner support member 23 gradually increases along the axial direction of the locking transmission shaft 21. By rotating the locking transmission shaft 21, the expansion member 24 and the inner support member 23 can move relative to each other along the axial direction of the locking transmission shaft 21, so that the inner support member 23 squeezes the expansion member 24 from the inside, causing the expansion member 24 to expand and contact with the first tube body 22, and gradually increasing the friction between the expansion member 24 and the first tube body 22, thereby realizing the telescopic locking of the first tube body 22.

[0047] In a preferred embodiment, the expansion member 24 includes a connecting ring 241 threadedly connected to the inner support member 23, and an expansion ring 242 squeezed by the inner support member 23. The connecting ring 241 and the expansion ring 242 are arranged along the axial direction of the locking transmission shaft 21, and the connecting ring 241 and the expansion ring 242 are snap-connected.

[0048] In this embodiment, the expansion member 24 is designed to be a combination of a connecting ring 241 and an expansion ring 242. The connecting ring 241 is used for threaded connection with the inner support member 23, and the expansion ring 242 is used to be squeezed by the inner support member 23. Since the threaded connection part and the squeezing part are staggered, the squeezing force on the expansion ring 242 will not be transmitted to the connecting ring 241, so that the expansion ring 242 can be easily deformed, and the connecting ring 241 can also maintain a stable threaded connection for a long time.

[0049] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
