Description

Technical Field

[0001] This utility model relates to the field of photographic equipment, specifically to a lever-type tripod head. Background Technology

[0002] A camera head is a core component in photographic equipment used to support the camera and stabilize the shooting angle. The locking / unlocking function of its ball joint directly affects the convenience and efficiency of shooting operations.

[0003] In existing technologies, the ball joint locking / unlocking of camera gimbals often employs a knob-type adjustment structure. For example, Chinese utility model patent CN221684159U discloses a gimbal and camera bracket that is easy to assemble. By loosening the locking component 60, the deformation part 13 loses its driving force and releases its pushing action on the inner locking sleeve 30, allowing the inner locking sleeve 30 to loosen the ball head 40, enabling the ball head 40 to rotate freely within the inner locking sleeve 30. When the shooting angle is adjusted, the locking component 60 is driven in the opposite direction to drive the deformation part 13 to push against the inner locking sleeve 30, so that the inner locking sleeve 30 presses against the ball head 40. However, the above structure has obvious drawbacks: First, the adjustment operation relies on manual operation, requiring both hands to be freed during shooting, making it difficult to quickly respond to angle adjustment needs and resulting in poor operational convenience; second, the knob adjustment requires turning multiple turns to reach the target state, resulting in slow response speed and failing to meet the needs of fast shooting scenarios.

[0004] To address the aforementioned issues, there is an urgent need for a gimbal that is more convenient to operate, responds faster, and has a more reliable structure. By optimizing the adjustment structure and simplifying the locking / unlocking operation steps, the adjustment efficiency and user experience during shooting can be improved. Utility Model Content

[0010] Preferably, the top of the movable housing 5 extends upward to form an annular protrusion 52, the bottom of the spherical connector 3 is provided with a through-hole 31 for the annular protrusion 52 to be inserted, and the inner sidewall of the spherical connector 3 above the through-hole 31 forms an annular retaining edge 32.

[0011] Preferably, the top surface of the ball joint 3 is provided with a first screw hole channel 11, and the top surface of the mounting base 4 is provided with a second screw hole channel 12. The ball joint 3 and the mounting base 4 are connected by screws passing through the second screw hole channel 12 and the first screw hole channel 11 in sequence. The top of the ball joint 3 is provided with a plurality of positioning protrusions 13, and the bottom of the mounting base 4 is provided with a slot 14 for the positioning protrusions 13 to be engaged.

[0012] Preferably, the mounting base 4 includes: a base plate 41 and a seat body 42 detachably mounted on the base plate 41. The base plate 41 is provided with a first movable mounting block 43 and a second movable mounting block 44 on opposite sides, which can move inward or outward. The first movable mounting block 43 includes a first main body portion 431 sandwiched between the seat body 42 and the base plate 41, a first clamping block 432 protruding from the first main body portion 431, and a first screw hole 433 opened on the first main body portion 431.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This design employs a lever-type transmission structure, replacing the manual knob adjustment of existing technologies, thus solving the pain point of traditional gimbals requiring two-hand operation and interrupting framing. During operation, only one hand needs to operate the lever to drive the horizontal drive shaft, which in turn moves the movable housing axially up and down, thus locking and unlocking the ball joint. Compared to the multi-turn knob adjustment method, the response speed is improved, eliminating the need for two hands and making it suitable for fast-viewing scenarios such as dynamic shooting and outdoor photography. Furthermore, the arc-shaped contact surface at the bottom of the lever fits snugly against the outer circumference of the horizontal drive shaft, ensuring even force distribution and eliminating the risk of slippage. Combined with the spring-loaded automatic reset design, releasing the lever automatically locks the ball joint, further simplifying the operation process.

[0017] 2. The locking structure employs a combination of annular protrusions, a through-hole, and annular retaining edges. When the movable housing moves upward, the annular protrusion engages with the bottom through-hole of the ball joint and abuts against the annular retaining edge, restricting the rotation and sway of the ball joint and ensuring strong locking stability. The mounting base features a double-sided sliding movable mounting block design. After initial positioning with positioning screws, the clamping blocks can move within the opening, adapting to loads of different sizes such as cameras and quick-release plates, significantly improving versatility. Furthermore, the connecting housing adopts a combined structure of an outer shell and an inner shell with vertical cracks. The elastic deformation capability of the inner shell can accommodate the deformation that occurs during locking / unlocking of the ball joint, improving fit while ensuring overall structural strength.

[0024] The following embodiments further illustrate the features of this utility model and other related features in detail, so as to facilitate understanding by those skilled in the art: like Figures 1 to 6 A lever-type gimbal, comprising: The gimbal base 1 includes a base shell 20 and a connecting shell 2 detachably connected to the top of the base shell 20. A ball joint 3 is embedded inside the connecting shell 2, and a mounting base 4 for mounting loads such as cameras is fitted on the top of the ball joint 3. A movable shell 5 is installed inside the gimbal base 1. The movable shell 5 is hinged to an operating lever 7 that can swing up and down via a transverse pivot 6. The movable shell 5 is rigidly connected to a transverse drive shaft 8 below the transverse pivot 6. The upper part of the operating lever 7 rotates with the transverse pivot 6 as a fulcrum, and the lower part abuts against the outer circumference of the transverse drive shaft 8. By moving / releasing the operating lever 7, the transverse drive shaft 8 is driven to move the movable shell 5 up and down along the axis of the gimbal base 1, thereby adjusting the locking or unlocking state of the ball joint 3. In practice, the mounting base 4 has screw holes on both sides, and the connecting housing 2 also has through holes on both sides. The operating lever 7 has a screw hole channel. The screw passes through the screw hole on one side of the mounting base 4, the through hole on one side of the connecting housing 2, and the screw hole channel of the operating lever 7, and then passes out to the screw hole on the other side of the mounting base 4, so that the transverse rotating shaft 6 is installed between the screw holes on both sides.

[0025] As described above, the gimbal in this case, through the arrangement of the movable housing 5, the operating lever 7, the horizontal rotating shaft 6, and the horizontal drive shaft 8, forms a lever-type transmission structure, replacing the manual knob adjustment of the prior art. It eliminates the need to free up both hands for operation, and the locking / unlocking operation of the ball joint can be completed with one hand or one foot during shooting, greatly improving the convenience of operation; moreover, the transmission path is short and direct, and the response speed is fast, which is suitable for the need for rapid angle adjustment in dynamic shooting scenarios; in addition, the above structure is simple and reliable, reducing easily worn parts such as threaded transmissions and extending service life.

[0026] like Figure 5As shown, in a preferred embodiment, an arc-shaped abutment surface 71 is formed on the lower end face of the operating lever 7. The curvature of the arc-shaped abutment surface 71 matches the curvature of the outer peripheral surface of the transverse drive shaft 8, ensuring complete contact between the two. Thus, the arc-shaped abutment surface 71 increases the contact area between the lever and the transverse drive shaft, resulting in uniform force distribution during operation and preventing slippage or wear caused by localized stress concentration. The close contact improves force transmission efficiency, reduces operational jerking, and optimizes the user experience.

[0027] like Figure 2 As shown, in a preferred embodiment, a bottom cover 9 is connected to the bottom of the movable housing 5. The bottom of the movable housing 5 is screwed and fixed to the external thread of the bottom cover 9 via an internal thread. A circular groove 51 is formed by an upward indentation on the side of the movable housing 5 near the bottom cover 9. The inner diameter of the groove 51 matches the outer diameter of the spring 10. The spring 10 is vertically installed between the groove 51 and the upper surface of the bottom cover 9. In this way, the spring provides a stable automatic reset force, and the movable housing can automatically move upward and the ball joint can automatically lock after the lever is released, without the need for manual return. At the same time, the spring also has a buffering effect, reducing the impact when the movable housing moves, reducing the wear and tear of the parts, and improving the smoothness of the lever operation.

[0028] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the top of the movable housing 5 extends upward to form an annular protrusion 52, and the bottom of the spherical connector 3 has a through-hole 31 that matches the size of the annular protrusion 52. An annular retaining edge 32 is integrally formed on the inner wall of the spherical connector 3 above the through-hole 31. Specifically, when the movable housing 5 moves upward, the annular protrusion 52 engages with the through-hole 31 and abuts against the annular retaining edge 32, thereby restricting the rotation / swing of the spherical connector and achieving locking. When the movable housing 5 moves downward, the annular protrusion 52 disengages from the through-hole 31, achieving unlocking. Thus, the locking and unlocking of the spherical connector are achieved through the cooperation of the annular protrusion, the through-hole, and the annular retaining edge. The locking is highly stable and there is no risk of slippage. Moreover, the structure is simple, requiring no additional locking components, reducing assembly difficulty.

[0029] like Figures 1-4As shown, the top surface of the ball joint 3 has a through-hole channel 11 along the axial direction, and the top surface of the mounting base 4 has a second threaded channel 12 coaxial with the first threaded channel 11. A first screw 100 passes through the second threaded channel 12 and the first threaded channel 11 in sequence to fix the mounting base 4 to the ball joint 3. Multiple positioning protrusions 13 are evenly distributed on the top of the ball joint 3, and multiple corresponding slots 14 are formed on the bottom of the mounting base 4 to fit the positioning protrusions 13. The positioning protrusions 13 are engaged in the slots 14. Thus, the screw connection ensures the reliability of the connection between the mounting base and the ball joint, the cooperation between the positioning protrusions and the slots achieves circumferential positioning, preventing the mounting base from rotating relative to the ball joint and ensuring stability after load installation; the screw tightening achieves axial fixation, further ensuring the stability of the mounting base.

[0030] like Figure 2 , 4 As shown in Figure 6, in a preferred embodiment, the mounting base 4 consists of a base plate 41 and a seat body 42 detachably mounted on the base plate 41. The base plate 41 has a first movable mounting block 43 and a second movable mounting block 44 on opposite sides, which can slide inwards or outwards along the longitudinal direction. The first movable mounting block 43 includes a first main body portion 431 clamped between the seat body 42 and the base plate 41, a first clamping block 432 integrally protruding from one side of the first main body portion 431, and a first screw hole 433 formed on the first main body portion 431. A first positioning screw 434 passes through the first screw hole 433 from below the base plate 41. The first movable mounting block 43 is initially positioned; the second movable mounting block 44 includes a second main body 441 clamped between the base 42 and the base plate 41, a second clamping block 442 integrally protruding on one side of the second main body 441, and a second screw hole 443 opened on the second main body 441. The second positioning screw 444 passes through the second screw hole 443 from the bottom of the base plate 41 to the top, thereby achieving the initial positioning of the second movable mounting block 44; the base 42 is provided with a first opening 421 and a second opening 422 respectively, corresponding to the positions of the first clamping block 432 and the second clamping block 442, for them to pass through and forming a limited movement space inside.

[0031] As described above, the mounting base in this case achieves precise clamping of loads of different sizes through the limiting movement of the first and second clamping blocks within the opening, resulting in stronger adaptability; the movable mounting block is clamped between the base body and the base plate, ensuring high structural stability and preventing loosening; the detachable base body and base plate design facilitates individual replacement of damaged parts, reducing maintenance costs. The positioning screws can be used for initial placement and positioning during installation.

[0032] like Figure 2 , 4As shown in Figures 6 and 7, in a preferred embodiment, the base 42 has recesses 45 on both sides corresponding to the outer sliding paths of the first movable mounting block 43 and the second movable mounting block 44, allowing them to slide out unobstructed. The outermost surfaces of both the first and second movable mounting blocks 43 and 44 are provided with anti-slip textured ribs 46, which are distributed in a continuous corrugated pattern to facilitate anti-slip operation when the movable mounting blocks are pushed by hand. Specifically, when an object is mounted on the base, causing the movable mounting blocks to slide outwards, a portion of the ribs protrudes through the recesses 45. When resetting is required, the movable mounting blocks can be manually pushed. The anti-slip textured ribs 46 increase the friction coefficient of the contact surface, making the pushing action more stable and facilitating quick adjustment of the clamping block spacing. Thus, the recesses 45 provide space for the maximum sliding stroke of the movable mounting blocks, preventing the base 42 from interfering with their sliding. The anti-slip textured ribs 46 increase the friction between the hand and the movable mounting blocks, making manual adjustment of the clamping block position easier and less prone to slippage, thus improving the human-computer interaction experience.

[0033] like Figures 1-2 As shown, at least three foldable support feet 15 are evenly hinged along the circumferential direction on the outer bottom of the gimbal base 1. The support feet 15 can be unfolded outward relative to the gimbal base 1 to a horizontal or tilted state, or they can be folded inward. In this way, in the unfolded state, the circumferential array of support feet forms a stable support structure, increasing the contact area between the gimbal and the ground, improving the stability of the gimbal, and adapting to different terrains; in the folded state, the support feet fit against the base, reducing the overall volume and making it easy to store and carry.

[0034] like Figure 2 As shown, in a preferred embodiment, the connecting housing 2 consists of an outer shell 21 and an inner shell 22 embedded inside the outer shell 21. The inner shell 22 has a first vertical slit 23 extending vertically along its axial direction, giving it a certain elastic deformation capability. Thus, the outer shell 21 ensures the overall structural strength of the connecting housing, and the first vertical slit 23 in the inner shell 22 allows it to adapt to the locking / unlocking of the ball joint 3, improving the fit between the inner shell 22 and the ball joint 3.

[0035] In summary, this utility model discloses a lever-type gimbal, comprising a gimbal base, a connecting housing, a ball joint, a mounting base, a movable housing, a horizontal rotating shaft, an operating lever, and a horizontal drive shaft. The movable housing is hinged to the operating lever via the horizontal rotating shaft, and its lower part abuts against the horizontal drive shaft. Operating the lever drives the movable housing to move axially up and down. The annular protrusion on the top of the movable housing engages with the through-hole and annular retaining edge of the ball joint, enabling quick locking / unlocking of the ball joint. The mounting base features sliding movable mounting blocks on both sides to accommodate different load sizes. The bottom of the movable housing has a spring return structure, the connecting housing adopts an elastic inner shell design, and the bottom of the gimbal base is hinged with a folding support foot. This utility model uses a lever-type transmission, allowing for one-handed operation, rapid response, stable locking, strong adaptability, durable structure, and convenient maintenance, making it suitable for rapid angle adjustment needs in various photography scenarios.

[0036] As stated above, this case protects a lever-type gimbal, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
