Description

Technical Field

[0001] This utility model relates to the field of gimbal frame technology, and in particular to a gimbal frame structure. Background Technology

[0002] In the current technology, as people's shooting needs increase, the demand for shooting quality and shooting scenes is also increasing. Various devices that assist smartphones in shooting have emerged, among which handheld gimbals are one of the devices that assist smartphones in shooting.

[0003] A search revealed Chinese patent application number 202420918383.X, which discloses a gimbal frame structure, including a gimbal body. The gimbal body has a gimbal frame at its bottom, with a cavity and square hole inside. The gimbal frame has an external threaded area on its exterior, and multiple through slots and obstacle avoidance slots are formed inside the gimbal frame. An internal threaded sleeve is fitted onto the outside of the gimbal frame, with a groove inside the internal threaded sleeve. A connecting block is located inside the cavity, and multiple protruding plates are fixedly mounted on the outside of the connecting block. A square rod is fixedly mounted at the bottom of the connecting block, and multiple frame components are located at the bottom of the square rod. Each frame component includes a toothed plate, which is fixedly connected to the square rod. A movable plate is located on one side of the toothed plate, and arc-shaped teeth are fixedly mounted on the outside of the movable plate, meshing with the toothed plate. A rotating shaft is fixedly inserted into the movable plate.

[0004] The aforementioned patent has the following shortcomings: the gimbal frame controls the opening or closing of the legs by rotating the internal threaded sleeve, thereby controlling the frame structure to be in a handheld or placed state, making it easy to switch states; however, in actual use, the engagement stroke of the internal threaded sleeve is relatively small (the thread pitch is small), making it inconvenient to quickly unfold or retract the support legs.

[0014] As a further improvement of this utility model: a fixed mounting pin is fixedly connected to the top of the lifting column, and a limit protection plate is fixedly installed on the outer wall of the fixed mounting pin.

[0015] As a further improvement of this utility model: a positioning mounting cylinder is fixedly connected to the bottom of the front side of the fixed connecting cylinder, and an internal threaded sleeve is fixedly installed inside the positioning mounting cylinder.

[0016] As a further improvement of this utility model: the internal thread of the internal threaded sleeve is fitted with a fixing bolt, and a rotating connecting ring is rotatably mounted on one end of the fixing bolt.
