[0022] Figure 1 and Figure 2 The present invention shows a schematic structural diagram of an embodiment of a pan / tilt head capable of quickly adjusting the tilt angle of the utility model. Figure 1 This is a schematic diagram of the overall structure of a gimbal that can quickly adjust the tilt angle. Figure 2 is a schematic diagram of the decomposition structure. Figure 1 and Figure 2 As shown, the pan / tilt head capable of quickly adjusting the tilt angle comprises: a base 1, a plurality of screws 2, a locking member 3, a movable member 4 and a platform 5, the bottom ends of the plurality of screws 2 are connected to the base 1, the top ends of the plurality of screws 2 are threadedly connected to the locking member 3, each screw 2 is sleeved with a first knob 21 for driving the screw 2 to rotate, the platform 5 is arranged on the movable member 4, and the movable member 4 is movably arranged on the locking member 3, so that the angle of the movable member 4 can be adjusted when the locking member 3 is loosened and the movable member 4 is fixed when the locking member 3 is locked.

[0023] It should be noted that, in this embodiment, the multiple screws 2 are evenly distributed in a ring shape.

[0024] Preferably, in this embodiment, the number of screw rods 2 is set to three, which are arranged in an equilateral triangle.

[0025] Specifically, in this embodiment, the platform 5 is set on the movable part 4, and the movable part 4 is then set on the locking part 3. A plurality of screws 2 are set between the base 1 and the locking part 3, and the screws 2 are threadedly connected to the locking part 3. When the inclination angle of the platform 5 needs to be adjusted, the locking part 3 is loosened, the movable part 4 is released, and a large angle adjustment can be performed. After the adjustment, the locking part 3 is locked to fix the movable part 4, and then the first knob 21 on the screw 2 is rotated to allow relative movement between the screw 2 and the locking part 3, and the bottom end of the screw 2 is restricted by the base 1. Therefore, the locking part 3 is tilted under the traction of the screw 2 to achieve fine-tuning of the inclination angle of the locking part 3, thereby achieving the purpose of fine-tuning the inclination angle of the platform 5, and the number of screws 2 is set to be multiple, and the inclination angle of the platform 5 can be fine-tuned from different positions.

[0026] In this embodiment, the locking piece 3 is loosened, the movable piece 4 is quickly adjusted to greatly adjust the inclination angle of the platform 5, and then the locking piece 3 is locked. The first knob 21 is adjusted to make the screw 2 and the platform 5 move relative to each other, so that the inclination angle of the locking piece 3 is fine-tuned by the screw 2 to achieve the purpose of fine-tuning the inclination angle of the platform 5. On the one hand, it can realize the rapid adjustment of the inclination angle of the pan-tilt head, and on the other hand, it ensures the adjustment accuracy of the inclination angle of the pan-tilt head, so that the user can quickly and accurately adjust the inclination angle of the pan-tilt head, and the user experience is better.

[0027] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, a plurality of first mounting holes 11 are provided on the base 1, and the bottom end of the screw rod 2 is hemispherically arranged. The first mounting hole 11 includes a curved surface portion 111 matching the bottom end of the screw rod 2, a through hole portion 112 and a bolt mounting portion 113, and the bolt mounting portion 113 is provided with a bolt 22, one end of the bolt 22 passes through the through hole portion 112 and is connected to the bottom end of the screw rod 2, and the diameter of the bolt 22 is smaller than the diameter of the through hole portion 112 so that a gap exists between the bolt 22 and the through hole portion 112.

[0028] It should be noted that when relative movement occurs between the screw rod 2 and the locking member 3 to adjust the inclination angle of the locking member 3, the screw rod 2 will tilt under the traction of the locking member 3. Therefore, in this embodiment, the bottom end of the screw rod 2 is set to a hemispherical shape, and then a curved surface portion 111 is set in the first mounting hole 11, so that when the screw rod 2 is tilted, the hemispherical shape of the bottom end of the screw rod 2 rotates in the curved surface portion 111, and the bottom of the screw rod 2 is connected to the base 1 through a bolt 22, and there is a gap between the bolt 22 and the through hole portion 112, so that when the screw rod 2 is tilted, the bolt 22 can also tilt in the through hole portion 112, thereby avoiding deformation of the connection between the bolt 22 and the screw rod 2.

[0029] Furthermore, a conical coil spring 24 is provided between the bolt 22 and the bolt mounting portion 113 , the thick end of the conical coil spring 24 abuts against the bolt mounting portion 113 , and the thin end of the conical coil spring 24 abuts against the bolt 22 .

[0030] Specifically, by providing a conical coil spring 24 between the bolt 22 and the bolt mounting portion 113 , when the screw rod 2 is released, it can return to its original position under the elastic action of the conical coil spring 24 .

[0031] Furthermore, the locking member 3 includes an unclosed annular locking portion 31, both ends of which are provided with screw holes (not shown in the figure), and the second knob 32 is screwed into the screw hole. The movable member 4 is arranged in the annular locking portion 31, and the annular locking portion 31 is locked or loosened when the second knob 32 is rotated.

[0032] Specifically, there is a certain gap between the two ends of the unclosed annular locking portion 31. By setting the annular locking portion 31, screw holes are set at both ends of the annular locking portion 31, and then a second knob 32 is set in the screw holes at both ends of the annular locking portion 31. By rotating the second knob 32, the gap between the two ends can be reduced or enlarged, thereby achieving the purpose of locking or loosening the movable part 4.

[0033] Furthermore, the movable member 4 is provided in a cylindrical shape, and the side wall of the movable member 4 is provided as an arc surface, and the inner side wall of the annular locking portion 31 is provided as an annular curved surface matching the arc surface.

[0034] Specifically, the side wall of the movable part 4 is arranged as an outwardly convex arc surface, and the inner side wall of the annular locking portion 31 is arranged as an inwardly concave annular curved surface. On the one hand, the annular locking portion 31 can fit more closely with the movable part 4 when locking, and fix the movable part 4 more firmly; on the other hand, the arrangement of the arc surface and the annular curved surface allows the movable part 4 to tilt in different directions to meet user needs.

[0035] Furthermore, the second knob 32 is provided with anti-slip teeth.

[0036] Specifically, by providing the anti-slip teeth on the second knob 32 , it is easier and more convenient for the user to rotate the second knob 32 .

The annular fixing portion 341 is fixedly connected to the second mounting hole 33, and the annular threaded portion 342 is provided with an internal thread (not shown in the figure), which is threadedly connected to the screw rod 2. The screw rod 2 is also sleeved with a third knob 23, and the third knob 23 includes a knob portion 231 sleeved on the annular threaded portion 342 and a limiting portion 232 threadedly connected to the screw rod 2. The height of the knob portion 231 is the same as that of the annular threaded portion 342, so that when the limiting portion 232 abuts against the annular threaded portion 342, the knob portion 231 abuts against the locking member 3.

[0038] Specifically, after fine-tuning the angle, the third knob 23 can be rotated until the knob portion 231 of the third knob 23 abuts against the bottom surface of the locking member 3, and the knob portion 231 is at the same height as the annular threaded portion 342. When the knob portion 231 abuts against the locking member 3, the limiting portion 232 abuts against the annular threaded portion 342. On the one hand, the threaded connection between the fixing nut 34 and the screw rod 2 can support the locking member 3. On the other hand, the abutment of the third knob 23 against the locking member 3 can also support the locking member 3, so that even if the camera equipment placed on the platform 5 is heavy, there will be no slippage between the fixing nut 34 and the screw rod 2.

[0039] Furthermore, the side wall of the third knob 23 is provided with anti-slip teeth.

[0040] Specifically, by providing the anti-slip teeth on the third knob 23 , it is easier and more convenient for the user to rotate the third knob 23 .
