[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 4 As shown, a pan head includes: a base 2 for installation on a cloth inspection machine, a first adjustment frame 3, a first adjustment mechanism 4, a second adjustment frame 5 and a second adjustment mechanism 6, the base 2 is rotatably provided with a first rotating shaft 7; the first adjustment frame 3 is rotatably connected to the first rotating shaft 7, the first adjustment frame 3 is rotatably provided with a second rotating shaft 8, and the second rotating shaft 8 is perpendicular to the first rotating shaft 7; the first adjustment mechanism 4 is simultaneously connected to the base 2 and the first adjustment frame 3, and is used to drive the first adjusting frame 3 to rotate around the axis of the first rotating shaft 7; the second adjustment frame 5 is rotatably connected to the second rotating shaft 8, and the second adjustment frame 5 is used to install a camera 100; the second adjustment mechanism 6 is connected to the first adjustment frame 3 and the second adjustment frame 5, and is used to drive the second adjusting frame 5 to rotate around the axis of the second rotating shaft 8.

[0033] In the present application, the base 2 and the first adjustment frame 3: the base 2 is used to be fixed on the cloth inspection machine, providing a stable fulcrum. The first adjustment frame 3 is rotatably connected to the base 2 through the first rotating shaft 7, allowing it to rotate around the axis of the first rotating shaft 7. The first adjustment mechanism 4 connects the base 2 and the first adjustment frame 3, responsible for driving the first adjustment frame 3 to rotate around the first rotating shaft 7, thereby adjusting the angle of the camera 100. The first adjustment frame 3 is provided with a second rotating shaft 8, which is perpendicular to the first rotating shaft 7. The second adjustment frame 5 is rotatably connected to the first adjustment frame 3 through the second rotating shaft 8, so that the second adjustment frame 5 can rotate around the second rotating shaft 8; the second adjustment mechanism 6 connects the first adjustment frame 3 and the second adjustment frame 5, and is used to control the rotation of the second adjustment frame 5 around the second rotating shaft 8, thereby adjusting the angle of the camera 100.

[0034] The camera 100 can be precisely adjusted in two directions by two mutually perpendicular rotating shafts and corresponding first adjustment mechanism 4 and second adjustment mechanism 6, which enhances the flexibility of operation and the scope of application. The first adjustment mechanism 4 and second adjustment mechanism 6 can be operated independently, allowing the user to precisely control the angle of the camera 100, which is crucial to improving the accuracy and efficiency of cloth detection.

[0035] Specifically, the first adjustment mechanism 4 includes a first fixed plate 41, a first worm 42 and a first worm wheel 43. The worm is rotatably arranged on the base 2. The first fixed plate 41 is fixed on the first adjustment frame 3. The first worm wheel 43 is fixed on the first fixed plate 41. The first worm 42 is meshed with the first worm wheel 43. The first fixed plate 41 has a first through hole in the middle, and the first rotating shaft 7 passes through the first through hole and is coaxial.

[0036] The first worm 42 is mounted on the base 2 and can be rotatably arranged, while the first worm wheel 43 is fixed on the first fixed plate 41 and meshes with the first worm 42. The combination of the worm and the worm wheel is a traditional mechanical transmission method, which is used to convert the rotational motion into the motion of the rotation angle of the first fixed plate 41, and finally adjust the angle of the camera 100.

[0037] The worm drive is characterized by a large transmission ratio, which allows fine adjustment. This design is particularly suitable for applications that require precise angle adjustment, such as the positioning of the camera 100 on a fabric inspection machine, and can achieve self-locking.

[0038] Specifically, at least one first limiting rod 21 is fixed on the base 2, and a first guide hole 31 corresponding to the first limiting rod 21 is opened on the first adjustment frame 3. The first limiting rod 21 passes through the first guide hole 31 and can abut against the inner walls at both ends of the first guide hole 31 to limit the rotation range of the first adjustment frame 3.

[0039] The cooperation between the first limiting rod 21 and the first guide hole 31 can very accurately limit the rotation angle of the first adjustment frame 3. This means that the adjustment range of the camera 100 can be strictly controlled between the required maximum and minimum angles, preventing damage or misoperation that may be caused by excessive rotation.

[0040] In the present application, there are two first limiting rods 21 .

[0041] Specifically, the second adjusting mechanism 6 includes a second fixed plate 61, a second worm 62 and a second worm wheel 63. The second fixed plate 61 is fixed on the second adjusting frame 5, the second worm wheel 63 is fixed on the second fixed plate 61, the second worm 62 is rotatably connected to the first adjusting frame 3, and the second worm 62 is meshed with the second worm wheel 63; the second fixed plate 61 is provided with a second through hole, and the second rotating shaft 8 passes through the second through hole and is coaxial.

[0042] The second worm 62 is rotated to drive the second worm gear 63 to rotate, the second worm gear 63 drives the second fixed plate 61 to rotate, and the second fixed plate 61 drives the second adjustment frame 5 to rotate.

[0043] The meshing of the worm and the worm gear provides very precise angle adjustment, allowing the operator to finely adjust the posture of the camera 100 to achieve an ideal shooting or observation angle.

[0044] Specifically, at least one second limiting rod 32 is fixed on the first adjustment frame 3, and a second guide hole corresponding to the second limiting rod 32 is opened on the second adjustment frame 5. The second limiting rod 32 passes through the second guide hole and can abut against the inner walls at both ends of the second guide hole to limit the rotation range of the second adjustment frame 5.

[0045] The cooperation between the second limit rod 32 and the second guide hole allows the rotation of the second adjustment frame 5 to be precisely limited, ensuring that the camera 100 operates between a specific maximum and minimum angle to avoid exceeding the set operating range. By physically limiting the rotation range, the second limit rod 32 can prevent the second adjustment frame 5 from colliding or being damaged when it rotates excessively, helping to protect the integrity and functionality of the mechanical components.

[0046] In the present application, there are two second limiting rods 32 .

[0047] Specifically, hand wheels are fixed to the ends of the first worm 42 and the second worm 62 .

[0048] The first worm 42 and the second worm 62 can be easily rotated manually for easy adjustment.

[0049] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship and movement status of the components in a certain specific posture, as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.
