[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The pan / tilt head of the utility model has rich adjustment functions and high flexibility, such as Figures 1 to 5 As shown, the multifunctional three-dimensional universal spherical head has been innovatively upgraded based on the original two-dimensional stepless adjustment, and the adjustment capability in three-dimensional space has been increased.

[0030] The base 1 is the basic component of the gimbal, designed to be firmly connected to various tripods, providing stability for the entire gimbal structure. The intermediate seat 2 is connected to the base 1 through a rotating mechanism, and a first stepless adjustment structure is designed between the two, which realizes the horizontal rotation adjustment of the intermediate seat 2 relative to the base 1.

[0031] The top seat 3 is connected to the middle seat 2 through a rotating mechanism, so that the top seat 3 can rotate in the vertical direction. A second stepless adjustment structure is also designed between the middle seat 2 and the top seat 3 to achieve vertical rotation adjustment of the top seat 3.

[0032] The quick-release plate holder 4 is located above the top seat 3 and is a key part for connecting photographic equipment. It is designed as a convenient quick-release structure to facilitate users to quickly load and unload cameras. A ball joint structure 5 is provided between the quick-release plate holder 4 and the top seat 3, which introduces a universal adjustment function to the entire pan / tilt system. The ball joint structure 5 is a connection method that can achieve free rotation in multiple directions. It enables the quick-release plate holder 4 to rotate around two other vertical axes in addition to rotating around one axis, thereby achieving true three-dimensional spatial adjustment.

[0033] The introduction of the ball joint structure 5 enables the gimbal to not only rotate horizontally and vertically, but also tilt and rotate at any angle, which provides photographers with unprecedented shooting freedom. Whether shooting upward, downward, sideways or at any oblique angle, the gimbal can easily cope with it, greatly expanding the creative scope of photographic works.

[0034] The first stepless adjustment structure and the second stepless adjustment structure can realize stepless adjustment of panoramic adjustment and stepless adjustment of pitch adjustment, and can freely and continuously adjust the damping size of horizontal rotation and vertical rotation, and can also be locked without gears, thereby realizing flexible and free panoramic adjustment and pitch adjustment. Moreover, each time the panoramic adjustment or pitch adjustment is made, there is no need to turn many circles each time, and the number of circles can be controlled according to one's needs, so the adjustment is relatively fast. In addition, due to the structural design of the first stepless adjustment knob and the second stepless adjustment knob, the adjustment process is smoother and does not require cumbersome operating steps.

[0035] It should be noted that, for the specific adjustment structures of the first stepless adjustment structure and the second stepless adjustment structure, reference may be made to the patent previously applied for by the applicant (application number: 2023232862533), which has been described in detail and will not be repeated here.

[0036] The ball joint structure 5 is the core component of the gimbal of the utility model, which gives the gimbal a highly flexible three-dimensional adjustment capability. More specifically, a ball head 51 is fixed to the quick-release plate clamping seat 4, which is the central rotating component of the ball joint structure. The ball head 51 is designed to be spherical so that it can move smoothly in three-dimensional space. The bottom surface of the top seat 3 is designed with a first arc surface 31, and the top surface of the clamping seat 52 is designed with a corresponding second arc surface 521. The two arc surfaces are a pair of precise curved surfaces in structure, which surround and clamp the ball head 51 from the upper and lower sides to form a stable and freely rotatable contact point.

[0037] The clamping seat 52 not only supports the ball head 51, but also fixes the top seat 3 with a screw on one side, ensuring the safety and stability of the overall structure. On the other side of the clamping seat 52, a unique ball joint locking structure is designed. The key to this structure is to adjust the gap between the top seat 3 and the clamping seat 52, and then adjust the clamping force of the ball head 51, ensuring the flexibility and accuracy of the pan / tilt adjustment.

[0038] The first pull rod 53 is fixedly connected to the clamp seat 52, and its upper part is designed as a threaded structure, which can cooperate with the adjustment knob 54. The adjustment knob 54 is located above the top seat 3. When the user rotates the adjustment knob 54, the knob 54 moves down along the thread of the first pull rod 53, thereby pressing the top seat 3 downward.

[0039] When the adjustment knob 54 rotates and moves downward, it causes the top seat 3 to move downward through the pressing action, further promoting the tight clamping between the top seat 3 and the clamping seat 52, thereby achieving a stable clamping of the ball head 51. This structural design not only ensures that the ball head 51 can be firmly positioned when needed, but also allows the user to quickly loosen or tighten the clamping force through a simple knob operation when the angle of the photographic equipment needs to be adjusted, thereby achieving fast and accurate angle adjustment.

[0040] In order to further improve the convenience of user operation and the practicality of adjustment, the adjustment knob 54 in the utility model adopts a flip-lock design. Compared with the traditional knob, the flip-lock knob provides a faster clamping and releasing function. The user can lock or release the ball joint structure 5 with a simple flip, making the adjustment process smoother and faster, saving adjustment time and improving shooting efficiency.

[0041] More specifically, the top seat 3 is provided with a first through hole 32 for the first pull rod 53 to pass through.

[0042] In the present invention, the ball head 51 adopts a hollow design, and a plurality of hollow holes 511 are opened in its internal structure. Such a design not only reduces the weight of the entire gimbal, but also ensures the structural strength of the ball head 51. The hollow holes 511 are not only conducive to reducing the use of materials and reducing the overall cost of the gimbal, but also may increase the friction between the contact surface of the ball head 51 and the clamping structure, further enhancing the stability during clamping.

[0043] More specifically, the quick-release plate clamping seat 4 has a dovetail groove left side wall 41, which forms a part of the dovetail groove structure. In order to cooperate with this structure, the movable block 42 is slidably connected along the left and right directions of the quick-release plate clamping seat 4, and the movable block is provided with a dovetail groove right side wall 421 corresponding to the dovetail groove left side wall 41. This allows the quick-release plate to be inserted into the dovetail groove and clamped and released by the movable block 42 sliding left and right. That is, an adjustment and locking mechanism for adjusting the left and right position of the movable block 42 is provided between the movable block 42 and the quick-release plate clamping seat 4.

[0044] More specifically, the adjustment and locking mechanism includes a receiving groove 43 provided on the upper part of the quick-release plate clamping seat 4, a fine-tuning nut 44 provided in the receiving groove 43, a side hole 45 provided on the right side wall of the quick-release plate clamping seat 4 and extending to the left into the receiving groove 43, a second through hole 422 provided on the movable block 42, and a second pull rod 46 which passes through the second through hole 422 and the side hole 45 from the outside to the inside in sequence and is threadedly connected to the fine-tuning nut 44. The outer end of the second pull rod 46 is rotatably connected to a main lever 47 which can press the movable block 42 inwardly to clamp the quick-release plate in the dovetail groove structure. When the main lever 47 rotates and fits against the side of the movable block 42, the main lever 47 presses the movable block 42 inwardly to effectively clamp the quick-release plate in the dovetail groove structure.

[0045] The end of the main lever 47 near its rotation center is usually designed with a compression surface and a relaxation surface around its rotation center, and the distance from the compression surface to its rotation center is smaller than the distance from the relaxation surface to its rotation center. The working principle of the lever is prior art and will not be repeated here.

[0046] In order to further ensure the safety and stability of the clamping, a safety buckle 48 is designed on the main buckle 47. The function of the safety buckle 48 is to limit the rotation of the main buckle 47, so as to prevent the main buckle 47 from loosening in extreme environments or due to misoperation, causing the quick-release plate to fall off and affecting the safety of the equipment. The safety buckle 48 is connected to the main buckle 47 by rotation, and it can rotate and press between the main buckle 47 and the movable block 42 to form an additional safety lock.

[0047] The design and operation of the safety trigger 48 is intended to further increase the stability and safety of the entire clamping structure. Its working principle involves a delicate mechanical interaction to ensure that the main trigger 47 can be reliably locked or released at critical moments. The following is a detailed description of the specific working principle of the safety trigger 48:

[0048] 1) Coordination between the pressing head 423 and the protrusion 481: On the movable block 42, the pressing head 423 is designed to have a pressing inclined surface. This inclined surface design enables the pressing head 423 to effectively cooperate with the protrusion 481 at the end of the safety trigger 48. The protrusion 481 is a protruding part that can be in close contact with the inclined surface of the pressing head 423.

[0049] 2) Rotation of the main trigger 47: When the user operates the main trigger 47 and rotates it to fit closely to the side of the movable block 42, the top pressure head 423 gradually contacts the protrusion 481 as the main trigger rotates. Due to the inclined design of the top pressure head 423, this contact generates an outward force, pushing the free end of the safety trigger 48 to rotate outward.

[0050] 3) Locking and releasing mechanism: As the free end of the safety trigger 48 rotates outward, the protrusion 481 gradually increases the pressure on the top pressure head 423, thereby locking the main trigger 47 in place. This locking action prevents the main trigger 47 from rotating due to external forces or accidental operation, ensuring the safe fixation of the quick release plate.

[0051] 4) Unlocking process: When the main trigger 47 needs to be released to adjust or uninstall the quick release plate, the user only needs to gently rotate the free end of the safety trigger 48 inward. This inward rotation action gradually reduces the pressure of the protrusion 481 and eventually separates from the inclined surface of the top pressure head 423, thereby releasing the lock of the main trigger 47.

[0052] Through this ingenious design, the safety trigger 48 not only provides a reliable safety locking mechanism, but also allows the user to easily and quickly lock and unlock through a simple rotating action, greatly improving the convenience of operation and the reliability of the entire equipment.

[0053] Through these complex mechanical interactions, the adjustment and locking mechanism not only provides fine adjustment capabilities, but also ensures a high degree of security and stability once locked. Users can easily adjust the position of the quick-release plate in the dovetail groove and quickly lock or release the quick-release plate with a simple rotation action without the use of any additional tools. This design greatly improves the efficiency of quick equipment replacement, while also ensuring the safety and stability of photographic equipment during use.

[0054] More specifically, a handle 6 is detachably connected to the top seat 3 to facilitate universal adjustment, which not only enhances the interaction between the user and the device, but also improves the flexibility of device operation.
