Description

Technical Field

[0001] This utility model relates to the field of photographic equipment, and in particular to a structure for quick switching between coarse and fine adjustment and a gimbal. Background Technology

[0002] A tripod head is a tool used in photography to connect shooting equipment and a tripod, and it also allows for adjustment of the shooting angle. To meet the needs of angle adjustment efficiency, tripod heads are equipped with coarse and fine adjustment mechanisms. However, in existing tripod heads, both the coarse and fine adjustment mechanisms are driven by gears, and an adjustment handle is used to link with either the coarse or fine adjustment mechanism. The adjustment process is as follows: first, the adjustment handle is moved to engage with the coarse adjustment mechanism; after coarse adjustment, the adjustment handle is moved again to disengage from the coarse adjustment mechanism and engage with the fine adjustment mechanism, at which point fine adjustment can be performed. However, with this type of tripod head, the adjustment handle may "skip teeth" due to the gear meshing when switching between coarse and fine adjustment, affecting the user experience. Therefore, there is an urgent need for a tripod head with a quick switching mechanism between coarse and fine adjustment to solve the above problems. Utility Model Content

For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Reference Figures 1 to 3 This utility model provides a structure for quick switching between coarse and fine adjustment, including a support base 10, an adjustment base 20, an adjustment handle 30, a worm gear 41, a worm 42, a planetary gear carrier 51, a sun gear 52, and several planetary gears 53.

[0029] The support base 10 is provided with a rotating cavity 11;

[0030] The adjusting seat 20 is rotatably mounted on the support seat 10, and the shooting device is mounted on the adjusting seat 20;

[0031] The worm gear 41 is rotatably disposed in the rotating cavity 11 and connected to the adjusting seat 20;

[0032] Worm 42 meshes with worm wheel 41;

[0033] The planetary gear carrier 51 is mounted on the support 10;

[0034] Sun gear 52 is mounted on worm gear 42;

[0035] Planetary gear 53 meshes with planetary gear carrier 51 and sun gear 52 and is rotatably connected to adjusting handle 30; worm gear 42 passes through adjusting handle 30.

[0036] The adjusting seat 20 can be finely adjusted when the worm gear 42 is rotated, or coarsely adjusted when the adjusting handle 30 is rotated.

[0037] In this utility model, reference is made to Figures 1-2 As one embodiment of this utility model, it can realize the angle adjustment of the shooting device in one dimension, such as the X-axis. Of course, two or three sets of quick-switching structures can also be used simultaneously to realize the angle adjustment of the shooting device in two or three dimensions. Specifically, the support 10 is provided with an adjustment groove that communicates with the rotating cavity 11 and the outside. The worm gear 42 is rotatably set in the adjustment groove and extends to the outside of the adjustment groove. During assembly, the worm gear 42 is inserted into the rotating cavity 11 through the adjustment groove until the sun gear 52 is located in the planet gear carrier 51. Then, the three planet gears 53 are installed on the adjustment handle 30 and placed between the sun gear 52 and the planet gear carrier 51. At this time, the worm gear 42 is inserted into the adjustment handle. The handle 30 extends beyond the adjusting handle 30, and then the worm wheel 41 is placed into the rotating cavity 11 and meshes with the worm 42. Finally, the adjusting seat 20 is connected to the worm wheel 41 so that the two can rotate synchronously. It should be noted that the worm wheel 41 also needs to be connected to the support seat 10 through the first limiting structure (but this does not affect the rotation of the worm wheel 41) to prevent the worm wheel 41 from disengaging from the rotating cavity 11. Similarly, the adjusting handle 30 also needs to be connected to the support seat 10 through the second limiting structure (but this does not affect the rotation of the adjusting handle 30) to prevent the worm wheel 41 from separating from the support seat 10. Both the first and second limiting structures can adopt existing technologies, which will not be elaborated here and should not be considered as a limitation of this utility model.

[0038] When adjusting the adjustment lever 20 (shooting equipment), first operate the adjustment lever 30 for coarse adjustment. When the coarse adjustment is in place, operate the worm gear 42 for fine adjustment until the desired angle is achieved. Finally, lock and hold the angle.

[0039] Reference Figures 1-3In some embodiments, a quick switching structure for coarse and fine adjustments further includes a first bearing 61 and a second bearing 62. The inner ring of the first bearing 61 is connected to one end of the worm gear 42, and the outer ring of the first bearing 61 is connected to one side of the support seat 10. The inner ring of the second bearing 62 is connected to the other end of the worm gear 42, and the outer ring of the second bearing 62 is connected to the other side of the support seat 10. By setting the first bearing 61 and the second bearing 62, rotational support is provided for the worm gear 42, reducing frictional resistance and improving the smoothness of adjustment.
