Abstract
Description
[Technical Field]
[0001] This utility model mainly relates to a three-dimensional gimbal quick release positioning structure. [Background Technology]
[0002] Current 3D gimbal products have an inconvenient quick-release knob operation method. Once the user operates the knob, they cannot release the pressure. This means the user must maintain a continuous twisting motion to rapidly rotate the gimbal. This operation method causes significant inconvenience in practical use. For example, in scenarios requiring rapid gimbal angle adjustments, users need to maintain a twisting hand position for an extended period, which not only easily leads to hand fatigue but also greatly limits operational flexibility. [Utility Model Content]
[0003] To address at least one of the aforementioned problems, this utility model proposes a new structural solution. The three-dimensional gimbal quick-release positioning structure adopts the following technical solution:
[0004] A three-dimensional gimbal quick-release positioning structure includes a main body, a rotary handle, and a positioning component;
[0005] The main body is equipped with a worm gear, and the rotary handle has a worm that passes into the main body and meshes with the worm gear.
[0006] The positioning assembly includes a spring, a positioning post, a reset button, and a pressure block. The main body has a cavity, in which the spring, positioning post, and reset button are installed, and the spring is connected to the positioning post. The pressure block is locked to the end of the cavity to prevent the positioning post from coming out of the cavity. The pressure block has an opening, through which the end of the positioning post protrudes from the cavity and connects to the rotary handle.
[0007] The main body has a first locking position, the rotary handle has a second locking position, the rotary handle is fitted with a torsion spring, the two ends of the torsion spring are respectively embedded in the first locking position and the second locking position, the rotary handle is reset by the torsion spring, the rotary handle has a locking groove, and the positioning pin is pushed by the spring and connected to the locking groove to control the rotation state of the rotary handle.
[0008] Preferably, the rotary handle includes a fine-tuning component and a rotating component, with a worm gear passing through the rotating component, and the rotating component and the worm gear being connected to the fine-tuning component.
[0009] Preferably, the cavity has a first opening and a second opening at its side and front ends, respectively. The positioning post extends partially from the first opening, and the reset button extends partially from the second opening. Both the positioning post and the reset button have inclined surfaces, and the inclined surfaces of the positioning post and the reset button are connected. The positioning post and the reset button are pressed against each other by the two inclined surfaces to make the positioning post and the reset button move relative to each other.
[0010] Preferably, the main body has a first cavity and a second cavity, the first cavity and the second cavity are perpendicular to each other; the first cavity and the second cavity are connected, the worm gear is installed in the first cavity, the rotating part is connected to the second cavity, and the worm passes through the second cavity and extends into the first cavity to mesh with the worm gear.
[0011] Preferably, the fine-tuning component and the worm gear are concentrically connected, and the fine-tuning component and the rotating component are eccentrically connected.

[0013] Preferably, the base has a protruding post, the worm gear has a through cavity, and the protruding post is connected to the through cavity.
[0014] The beneficial effects of this utility model compared with the prior art are:
[0015] In this design, the worm gear and worm wheel can be separated by rotating the rotary handle. Upon releasing the handle, the positioning pin engages with the slot on the handle, keeping the handle in the separated state. At this point, the main body can be rotated freely and quickly. After rotating to the correct position, pressing the reset button retracts the positioning pin, and the handle automatically springs back under the action of the torsion spring, causing the worm gear and worm wheel to re-engage and reposition, achieving a rapid release positioning function. It boasts advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0025] The preferred embodiment provided by this utility model is as follows: Figures 1-6 As shown, a three-dimensional gimbal quick-release positioning structure includes a main body 1, a rotary handle 2, and a positioning component 3.
[0026] The main body 1 is provided with a worm gear 11, and the rotary handle 2 has a worm 21, which passes into the main body 1 and meshes with the worm gear 11. Furthermore, the main body 1 is provided with a first cavity 12 and a second cavity 13, which are perpendicular to each other. The first cavity 12 and the second cavity 13 are connected. The worm gear 11 is installed in the first cavity 12, and the rotating part 23 is connected to the second cavity 13. The worm 21 passes through the second cavity 13 and extends into the first cavity 12 to mesh with the worm gear 11.
[0027] The positioning assembly 3 includes a spring 31, a positioning post 32, a reset button 33, and a pressure block 34. The main body 1 has a cavity 14. The spring 31, the positioning post 32, and the reset button 33 are installed in the cavity 14, and the spring 31 is connected to the positioning post 32. The pressure block 34 is locked to the end of the cavity 14 to prevent the positioning post 32 from coming out of the cavity 14. The pressure block 34 has an opening 35, and the end of the positioning post 32 passes through the opening 35 and extends out of the cavity 14 to connect with the rotary handle 2.
[0028] The main body 1 is provided with a first locking position 15, and the rotary handle 2 is provided with a second locking position 24. The second locking position 24 is located on the rotating part 23. The rotary handle 2 is sleeved with a torsion spring 25. The two ends of the torsion spring 25 are respectively embedded in the first locking position 15 and the second locking position 24. The rotary handle 2 is reset by the torsion spring 25. The rotary handle 2 is provided with a slot 26. The positioning post 32 is pushed by the spring 31 and is movably connected to the slot 26 to control the rotation state of the rotary handle 2.
[0029] The rotary handle 2 includes a fine-tuning component 22 and a rotating component 23. A worm gear 21 passes through the rotating component 23, and the rotating component 23, worm gear 21, and fine-tuning component 22 are connected. When the rotating component 23 rotates, it will drive the fine-tuning component 22 and worm gear 21 to rotate. When the fine-tuning component 22 is rotated, the worm gear 21 will rotate relative to the rotating component 23.
[0030] The fine-tuning component 22 and the worm gear 21 are concentrically connected, while the fine-tuning component 22 and the rotating component 23 are eccentrically connected. The rotating component 23 and the second cavity 13 are concentrically connected. The eccentric connection allows the rotating component 23 to rotate the fine-tuning component 22 and the worm gear 21 without affecting the rotation of the worm gear 21 by the fine-tuning component 22. The first cavity 12 is open at both ends. An upper washer 16 is installed at the upper end, and a base 17 is installed at the lower end. The upper washer 16 and the base 17 are locked together by screws. The worm gear 11 is encapsulated in the first cavity 12 by locking the upper washer 16 and the base 17 together. The base 17 has a protrusion 18, and the worm gear 11 has a through cavity 19, with the protrusion 18 entering the through cavity 19. The worm gear 11, the base 17, and the upper washer 16 are connected by a conventional snap-fit method.
[0031] The cavity 14 has a first opening 36 and a second opening 37 at its side and front ends, respectively. A positioning post 32 partially extends from the first opening 36, and a reset button 33 partially extends from the second opening 37. Both the positioning post 32 and the reset button 33 have inclined surfaces 38, and these inclined surfaces 38 are connected. The positioning post 32 and the reset button 33 are pressed against each other by the two inclined surfaces 38, causing them to shift relative to each other. Since the reset button 33 is confined to the second opening 37, and the area of the second opening 37 is the same as the cross-sectional area of the reset button 33, the reset button 33 can only be pressed into the cavity 14. When the reset button 33 is pressed inward, it is pressed against the two inclined surfaces 38, pushing the positioning post 32 to move along the cavity 14, causing the end of the positioning post 32 to extend out of the cavity 14 and contact the rotating component. Furthermore, the end of the positioning post 32 extends out of the cavity 14 from the opening 35 of the pressure block 34.
[0032] Operating Procedure: A torsion spring 25 is fitted onto the knob handle 2, with both ends of the torsion spring 25 connected to the main body 1 and the knob handle respectively, thus giving the knob handle elasticity. A spring 31 is connected to the positioning pin 32, and under the push of the spring 31, the end of the positioning pin 32 is always pressed against the end face of the rotating part 23. The fine-tuning part 22 and the rotating part 23 have an eccentric connection structure. Rotating the handle separates the worm gear 21 and the worm wheel 11. At the same time, when the slot 26 of the knob handle 2 rotates to the position of the positioning pin 32, the positioning pin 32 is inserted into the slot 26, thereby restricting the knob handle 2 from continuing to rotate. At this time, the handle can be released, and the worm wheel 11 is in a free-rotating state. The base 17 and the upper washer 16 rotate with the worm wheel 11, allowing the main body 1 to be quickly rotated to the required angle.
[0033] When unlocking is required, press the reset button 33. The inclined surfaces 38 of the reset button 33 and the positioning post 32 press against each other to push the positioning post 32 backward. The positioning post 32 disengages from the slot 26 to complete the unlocking. Under the action of the torsion spring 25, the handle engages the worm gear 21 and the worm wheel 11 to limit the rotation of the worm wheel 11.
