[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] Reference Figure 1 and Figure 7A photographic pan head includes: a housing 100, a mounting seat 200, a connecting seat 300, a self-balancing mechanism 700 and a conversion mechanism 400; the mounting seat 200 is arranged in the housing 100; a hollow connecting ball head 500 is arranged on the connecting seat 300, and an opening 530 is arranged at the bottom of the connecting ball head 500; the self-balancing mechanism 700 is arranged on the mounting seat 200, and the mounting seat 200 passes through the opening 530 and extends the self-balancing mechanism 700 into the connecting ball head 500; the conversion mechanism 400 is arranged on the connecting seat 300, the connecting ball head 500 has a first state that can be universally rotated relative to the housing 100, and the connecting ball head 500 has a second state that can only be pitched relative to the housing 100, and the conversion mechanism 400 can make the connecting ball head 500 mutually convert between the first state and the second state. The connecting seat 300 can be used to connect with photographic equipment. The connecting ball head 500 sleeved on the outside of the mounting base 200 can perform universal motion relative to the mounting base 200, so as to adjust the orientation angle of the connecting base 300 in multiple directions. In the process of adjusting the angle of the connecting base 300, the universal motion of the connecting ball head 500 can be converted into a rotation that can only be performed in the pitch direction by using the conversion mechanism 400. By using the conversion mechanism 400, the angle adjustment process of the connecting base 300 can be divided into horizontal angle adjustment and pitch angle adjustment, so that the connecting base 300 can be adjusted to the target angle more intuitively and effectively. At the same time, when adjusting the horizontal angle of the connecting base 300, the connecting ball head 500 can obtain the support effect of the self-balancing mechanism 700, so that the deadweight of the photographic equipment is difficult to affect the horizontal rotation of the connecting ball head 500, so that a more precise adjustment effect can be achieved.

[0039] In certain embodiments, reference Figure 2 The connection base 300 is provided with a connection structure 350 for connecting with the photographic device. The connection structure 350 can realize the connection between the connection base 300 and the photographic device, or release the connection effect between the connection base 300 and the connection device, so that the connection device can be fixed on the connection base 300 and get support from the photographic head.

[0040] Specifically, the connection structure 350 includes a connection knob, which is connected to a connection pin through a threaded structure, and the connection pin can extend out of the connection seat 300 and connect to the photographic device, or extend into the connection seat 300. Of course, the specific configuration of the connection structure 350 is not unique, but can be adjusted according to actual conditions, which is not limited here.

[0041] In certain embodiments, reference Figure 3The self-balancing mechanism 700 includes an elastic reset component. When the connecting ball head 500 is pitched, the elastic reset component can elastically apply a force to the connecting ball head 500 in the opposite direction of the pitch rotation of the connecting ball head 500. When the connecting seat 300 drives the photographic device to adjust the pitch angle, the connecting ball head 500 will be subjected to the torque caused by the deadweight of the device, which can easily cause the connecting ball head 500 to automatically sag, bend or even break. The elastic reset component can apply a balancing force to the connecting ball head 500, thereby balancing the torque caused by the deadweight of the photographic device, thereby alleviating the damage to the connecting ball head 500, so as to avoid the connecting ball head 500 from automatically sagging, bending or even breaking.

[0042] In certain embodiments, reference Figure 8 The self-balancing mechanism 700 includes a connecting block 420 disposed in the connecting ball head 500, and the connecting block 420 can be connected to the connecting ball head 500; a spindle 710 is disposed on the mounting seat 200, and the connecting block 420 is movably sleeved on the spindle 710 and can be turned relative to the spindle 710; and the elastic reset component includes a torsion spring 720 wound on the spindle 710 and abutting against the connecting block 420. After the connecting block 420 is connected to the connecting ball head 500, when the connecting ball head 500 drives the connecting block 420 to turn relative to the spindle 710, the torsion spring 720 will apply a reverse elastic force to the connecting block 420, thereby alleviating or offsetting the torque caused by the deadweight of the photographic equipment, thereby effectively avoiding the problem of the connecting ball head 500 automatically sagging, bending or even breaking.

[0043] It is conceivable that the self-balancing mechanism 700 may also be composed of other components, such as springs (not shown) disposed on both sides of the connecting block 420, and the connecting ball head 500 will compress the springs when rotating, and the springs provide reverse support force for the connecting ball head 500. Of course, the specific configuration of the self-balancing mechanism 700 is not unique, but can be adjusted according to actual conditions, which is not limited here.

[0044] In certain embodiments, reference Figure 8 There are two torsion springs 720, which are respectively arranged on both sides of the connection block 420. The two torsion springs 720 can respectively apply elastic force to the connection block 420 from the positive and negative directions of the connection block 420. The torsion springs 720 on both sides can respectively apply elastic force to the connection block 420 from both sides of the connection block 420. Therefore, no matter whether the connection ball head 500 drives the connection block 420 to rotate in the pitch direction or the elevation direction, the torsion spring 720 can relieve or offset the force for the connection ball head 500, thereby achieving a self-balancing effect, thereby effectively avoiding the problem of the connection ball head 500 automatically sagging, bending or even breaking.

[0045] In certain embodiments, reference Figure 4The conversion mechanism 400 includes a connection block 420 that is flippably disposed on the mounting seat 200, and a non-circular slot 425 is disposed on the connection block 420; a latch 410 is movably disposed on the connecting seat 300, and the latch 410 can move through the connecting ball head 500 and be inserted into the slot 425. After the latch 410 is inserted into the slot 425, the latch 410 will connect the connection block 420 and the connecting seat 300. Thereafter, even if a horizontal rotation force is applied to the connecting seat 300, the non-circular slot 425 will prevent the latch 410 from rotating, but can only follow the connection block 420 to perform pitch flip relative to the mounting seat 200. As a result, a locking effect in the horizontal direction is obtained between the mounting seat 200 and the connecting seat 300, so that the pitch direction can be adjusted separately.

[0046] In certain embodiments, reference Figure 4 , a rotating disk 450 that can only rotate is provided on the connection seat 300, and a threaded hole is provided in the middle of the rotating disk 450; a passage 550 is provided on the connecting ball head 500, and the connecting block 420 is located inside the connecting ball head 500; the latch 410 is threadedly connected with the threaded hole, and the latch 410 can pass through the passage 550 and be inserted into the slot 425. When the rotating disk 450 rotates, it will drive the latch 410 to perform a spiral motion through the threaded hole, so that the latch 410 can directly and effectively move relative to the passage 550 and be inserted into the slot 425. As a result, the connecting block 420 can drive the connecting ball head 500 to rotate in the pitch direction through the latch 410, and achieve the effect of limiting the horizontal rotation of the connecting ball head 500.

[0047] Specifically, knurling is arranged on the peripheral side wall of the rotating disk 450. The knurling can effectively increase the friction force of the rotating disk 450, so that the rotating disk 450 is easier to be driven.

[0048] In certain embodiments, reference Figure 5, further comprising: a base 190, a first clamping assembly 630 and a second clamping assembly 670, wherein the base 190 is rotatably disposed at the bottom of the housing 100; the first clamping assembly 630 is disposed inside the housing 100 and can relatively clamp the connecting ball head 500 and the housing 100; the second clamping assembly 670 is disposed inside the housing 100 and can relatively clamp the housing 100 and the base 190. After the first clamping assembly 630 clamps the connecting ball head 500, the connecting ball head 500 will be relatively fixed between the housing 100. At this time, the housing 100 can be driven to rotate horizontally relative to the base 190, thereby driving the clamped connecting ball head 500 to rotate horizontally together, thereby achieving the effect of adjusting the horizontal angle of the connecting ball head 500 under the condition of locking the pitch rotation of the connecting ball head 500. The second clamping assembly 670 can clamp the housing 100 and the base 190, so that the connecting ball head 500 is completely fixed, thereby performing a stable shooting operation.

[0049] In certain embodiments, reference Figure 5 The first clamping assembly 630 includes: a first limiting ring 633, a second limiting ring 637, a push seat 635 and a first control end 631, the first limiting ring 633 and the second limiting ring 637 respectively surround the connecting ball head 500 from both sides of the connecting ball head 500; the first limiting ring 633 and the second limiting ring 637 can move relative to each other to approach and clamp the connecting ball head 500; the push seat 635 is installed in the shell 100, and one of the first limiting ring 633 and the second limiting ring 637 is installed on the push seat 635; a turbine worm gear pair 634 is arranged in the shell 100, and the first control end 631 is connected to the push seat 635 through the turbine worm gear pair 634. When the first control end 631 drives the worm gear pair 634 to rotate, the push seat 635 will be lifted by the worm gear pair 634, thereby pushing the first limit ring 633 or the second limit ring 637, so that the first limit ring 633 and the second limit ring 637 are relatively close to each other and the connecting ball head 500 is clamped. When the first control end 631 moves in the opposite direction, the push seat 635 will automatically sink under its own weight, thereby loosening the connecting ball head 500. As a result, the connecting ball head 500 is effectively clamped or loosened, thereby effectively achieving the fixing effect between the connecting ball head 500 and the base 190.

[0050] Specifically, the first control end 631 includes a second knob, the worm gear pair 634 includes a worm gear and a worm gear meshing with each other, and the worm gear is connected to the second knob. A boss is provided on the worm gear, and a groove is provided on the push seat 635. The boss extends into the groove and can drive it to rotate.

[0051] Specifically, the radial dimension of the middle of the connecting ball head 500 is larger than the radial dimensions of the upper and lower ends thereof, and the radial dimensions of the first limiting ring 633 and the second limiting ring 637 are both smaller than the radial dimension of the middle of the connecting ball head 500. When the first limiting ring 633 and the second limiting ring 637 are relatively close, they will gradually approach the middle of the connecting ball head 500 and clamp the middle of the connecting ball head 500, so that the connecting ball head 500 and the push seat 635 are relatively fixed.

[0052] In certain embodiments, reference Figure 6 The second clamping assembly 670 includes: a second control end 671 and a horizontal seat 676, wherein the second control end 671 is connected to a wedge block 678 and can drive the wedge block 678 to move; the horizontal seat 676 is disposed on the base 190, and a wedge-shaped notch 679 is disposed on the horizontal seat 676, and the wedge block 678 is movably disposed in the wedge-shaped notch 679. When the wedge block 678 moves, it will extend into the wedge-shaped notch 679. In the process of the wedge block 678 gradually extending, the wedge block 678 and the wedge-shaped notch 679 will push each other, thereby pressing the horizontal seat 676 and the base 190 against each other, so that the two cannot move against each other, thereby effectively achieving a fixing effect between the connecting ball head 500 and the base 190.

[0053] Specifically, the second control end 671 includes a first knob, which abuts against the outer wall of the housing 100; the first knob is connected to a knob screw 672, which is threadedly connected to the housing 100 and connected to the wedge block 678. When the first knob rotates, the knob screw 672 will be driven to rotate together, and when the knob screw 672 rotates, it will move axially relative to the housing 100, thereby effectively driving the wedge block 678 to move relative to the wedge notch 679.

[0054] In certain embodiments, reference Figure 1 At least three legs 800 are connected to the lower part of the base 190. More than three legs 800 can stably and effectively support the base 190, so that the housing 100 can be propped up to a certain height, thereby facilitating the shooting operation.

[0055] Specifically, three legs 800 are hinged at the lower portion of the housing 100 .

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
