[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] This utility model embodiment proposes a support device; please refer to [link / reference]. Figures 1 to 6Such as tripods, monopods or other support devices, the following uses a tripod and a camera as examples. The support device is used to support the camera and other photography equipment for shooting. The photography equipment in this embodiment can be a mobile phone, camcorder, action camera, camera, monitor, etc. The following uses a camera as an example for explanation.

[0040] The support device includes a mounting base 200 and a gimbal 100. The mounting base 200 is rotatably connected to the legs. The gimbal 100 includes a gimbal seat 10 and a locking assembly 20. The gimbal seat 10 can be directly locked to the camera by screws, or it can be mounted on the gimbal seat 10 by other brackets or photography accessories, such as a cage or a damping gimbal. The locking assembly 20 is used to lock the gimbal seat 10 onto the tripod mounting base 200. The mounting base 200 has through holes at the top and bottom. The gimbal seat 10 has a screw 11. The gimbal seat 10 is located at the upper end of the mounting base 200, and the screw 11 passes through the through holes. The locking assembly 20 is located at the lower end of the mounting base 200.

[0041] When the locking assembly 20 locks the gimbal mount 10 onto the mounting base 200, the mounting base 200 cannot rotate relative to the gimbal mount 10. That is, the upper end of the mounting base 200 abuts against the lower end of the gimbal mount 10, and the lower end of the mounting base 200 abuts against the upper end of the locking assembly 20. When there is vertical movement space or gap between the locking assembly 20 and the gimbal mount 10 and the mounting base 200, the gimbal mount 10 can be moved to rotate relative to the mounting base 200, thereby adjusting the camera shooting angle. The operation is simple and convenient.

[0042] In some embodiments, to facilitate rotation of the gimbal base 10 relative to the mounting base 200, the gimbal base 10 has a first bowl-shaped portion 12, and the mounting base 200 includes a second bowl-shaped portion 202. The second bowl-shaped portion 202 is configured with a first bowl-shaped groove 201, and the first bowl-shaped portion 12 is accommodated in the first bowl-shaped groove 201. The locking assembly 20 includes a top support 32, which is configured with a second bowl-shaped groove 321, and the second bowl-shaped portion 202 is accommodated in the second bowl-shaped groove 321. When the gimbal base 10 rotates relative to the mounting base 200, the first bowl-shaped portion 12 rotates in the first bowl-shaped groove 201, and at the same time, the second bowl-shaped portion 202 rotates in the second bowl-shaped groove 321. After adjusting the preset position, the locking assembly 20 cooperates with the screw 11 to lock and fix the gimbal base 10 and the mounting base 200 relative to each other.

[0043] To enable quick and convenient locking of the gimbal base 10 and mounting base 200, the locking component 20 can be implemented in various ways, such as in one embodiment:

[0044] Please see Figures 4 to 6The locking assembly 20 includes a handle body 30, a gear 40, and a locking assembly 50. The handle body 30 facilitates the user's grip and operation of the locking assembly 20. The upper end of the handle body 30 is recessed with a receiving hole 31. The gear 40 has a plurality of first teeth 41 circumferentially distributed and adapted to the external thread of the screw 11. The locking assembly 50 and the gear 40 are both mounted on the handle body 30, and the locking assembly 50 selectively engages with the gear 40. Part of the gear 40 extends into the receiving hole 31.

[0045] After assembly, the engaging component engages and locks with the gear 40. When the engaging component 50 is actuated to separate and unlock from the gear 40, the external thread of the screw 11 drives the gear 40 to rotate when the screw 11 extends into the receiving hole 31. When the engaging component 50 engages and locks with the gear 40, the external thread of the screw 11 engages with the gear 40 to limit the sliding of the screw 11 relative to the inner wall of the receiving hole 31. The screw 11 cannot be pulled inward or outward. The locking and unlocking operations are convenient and fast, saving time and effort and improving the user experience.

[0046] In some embodiments, such as Figure 6 As shown, the engaging assembly 50 includes an engaging member 52 and at least one elastic member 53. The engaging member 52 is provided with a second tooth 41 that is adapted to the first tooth 41 of the gear 40. The elastic member 53 applies a force to engage the engaging member 52 with the gear 40. After the engaging member 52 is actuated, the engaging member 52 separates from the gear 40. After the engaging member 52 is released, the elastic member 53 drives the engaging member 52 to reset. The structure is simple and compact, and convenient for production and installation.

[0047] The elastic element 53 can be a compression spring, which can be arranged along the extension direction of the handle body 30 or laterally. The engaging element 52 can be located on the outer or bottom side of the gear 40. The engaging element 52 can be directly operated by hand; for example, one end of the engaging element 52 can extend beyond the outside of the handle body 30, allowing for direct manual pressing or pulling away from the gear 40. Of course, in some embodiments, the user can also drive the engaging element 52 away from the gear 40 using other driving structures or components, as detailed below:

[0048] like Figure 5 and Figure 6 As shown, the engaging assembly 50 also includes a pull member 51, which has a through groove (not shown) extending vertically. The pull member 51 is a cylindrical sleeve and is slidably sleeved on the handle body 30 (the handle body 30 passes through the through groove). The engaging member 52 has one end of the second tooth 41 extending out of the through groove. One end of the elastic member 53 is connected to the other end of the engaging member 52 away from the second tooth 41, and the other end of the elastic member 53 is connected to the handle body 30.

[0049] In this design, pulling down the pull member 51 drives the locking member 52 to separate from the gear 40. After releasing the pull member 51, the locking member 52 drives the pull member 51 to reset, which conforms to human operating habits. Of course, the pull member 51 can also be pulled upwards, without limitation.

[0050] In some embodiments, such as Figure 6 As shown, for ease of installation and production, the handle body 30 is symmetrically recessed on the outer side of the pull member 51 with a first receiving groove and a second receiving groove. There are two elastic members 53, named the first elastic member 53 and the second elastic member 53 respectively. The first elastic member 53 and the engaging member 52 are located in the first receiving groove, and one end of the engaging member 52 with the second tooth 41 extends out of the first receiving groove. The second receiving groove contains the second elastic member 53 and the connecting member 54. One end of the connecting member 54 extends into the inner side of the upper end of the pull member 51. The second elastic member 53 applies a force to the connecting member 54 to hold the inner side of the upper end of the pull member 51.

[0051] When the pulling member 51 is pulled, the locking member 52 and the connecting member 54 are driven to move away from the gear 40, and the operation is stable. The first elastic member 53 and the second elastic member 53 are both compressed. After the locking member 52 is released, the first elastic member 53 pushes the connecting member 54 to reset, and the second elastic member 53 pushes the locking member 52 to reset. At the same time, the connecting member 54 and the locking member 52 drive the locking member 52 to reset.

[0052] In some embodiments, the handle body 30 includes a hand-held portion and a top-holding member 32 rotatably connected to the hand-held portion. When the engaging assembly 50 is engaged and locked with the gear 40, the top-holding member 32 can abut against the lower end of the mounting base 200 to be fixed on the mounting base 200, or the top-holding member 32 can release the lower end of the mounting base 200 so that the screw 11 can rotate relative to the mounting base 200.

[0053] In some embodiments, the handle body 30 further includes a C-shaped member sleeved on the handle body 30, and the C-shaped member is located between the top support member 32 and the pull member 51. The C-shaped member has a groove for receiving the gear 40, and the groove communicates vertically with the first receiving groove.

[0054] In some embodiments, to improve the user's grip, the outer surface of the handle body 30 may be made of silicone or sponge.

[0055] In summary, during the process of installing the gimbal 100 on the tripod mounting base 200, pulling down the pull member 51 drives the engaging member 52 to separate from the gear 40. When the free end of the screw 11 of the gimbal base 10 passes through the through hole of the mounting base 200 and extends into the receiving hole 31 of the handle body 30, the external thread of the screw 11 drives the gear 40 to rotate by meshing with the first tooth 41 of the gear 40. After the screw 11 extends into the preset position, the pull member 51 is released. The first elastic member 53 and the second elastic member 53 simultaneously push the pull member 51 to reset. Then, the second tooth of the engaging member meshes with the first tooth 41 of the gear 40 again, thereby locking the screw 11 and the gear 40 together.

[0056] The specific structure of the locking component is as described in the above embodiments. Since this photographic equipment adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0057] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
