Technical Field
[0001] The utility model relates to a focusing fixture, in particular to a fixture for focusing a micro camera. Background Art
[0002] As is well known, camera products have been widely used in various industrial products, such as mobile phones, computers, etc. With the gradual improvement of circuit integration and the acceleration of the miniaturization process of industrial products. At present, miniaturizing the cameras configured in industrial products has become an industry trend. Products equipped with cameras need to be subjected to focusing tests when leaving the factory. With the increasing speed of camera miniaturization, the current traditional focusing fixtures can no longer meet the needs of focusing tests, and this is the main shortcoming of the existing technology. Content of the Utility Model
[0003] The technical solution adopted by the utility model is as follows: a micro camera focusing fixture, characterized in that: it includes a camera fixing hole and an adjusting disk. The camera fixing hole is arranged at the central position of the adjusting disk. The adjusting disk includes an outer ring wall, a connecting disk, a conical disk and a central functional platform. Among them, the outer ring wall is arranged outside the connecting disk, and an open cavity is formed by surrounding the inner surface of the outer ring wall. The conical disk is arranged inside the connecting disk. The connecting disk is connected between the outer ring wall and the conical disk. The conical disk has an inclined inner side surface and an inclined outer side surface, and a conical cavity is formed by surrounding the inclined inner side surface of the conical disk. The central functional platform protrudes from the lower end of the conical disk. The camera fixing hole is arranged in the central functional platform. The camera fixing hole has a light outlet, a clamping interface and a hole inner wall. The hole inner wall is connected between the light outlet and the clamping interface, and a hole cavity is formed by surrounding the hole inner wall. The hole cavity, the conical cavity and the open cavity are communicated together to form a light outlet channel. Several clamping grooves are arranged on the clamping interface. Corresponding to the several clamping grooves, several clamping blocks are arranged around the camera. The several clamping grooves correspond to the several clamping blocks one by one.
[0004] The beneficial effect of the utility model is as follows: when adjusting by using the utility model, the camera fixing hole is sleeved on the camera, so that several clamping grooves are correspondingly clamped on several clamping blocks, and the adjusting disk is rotated. By driving the camera to rotate through the adjusting disk, the purpose of focusing test on the camera is achieved. During this process, the camera can collect light through the light outlet channel. The conical disk and the central functional platform of the utility model protrude above the camera fixing hole as a whole, so as to achieve the effect of facilitating the rotation of the adjusting disk.

[0011] As Figures 1 to 6 shown, a focusing jig for a micro camera includes a camera fixing hole 10 and an adjusting disk 20, and the camera fixing hole 10 is arranged at the central position of the adjusting disk 20.
[0012] When in use, the focusing jig is assembled on the camera 1, and the adjusting disk 20 is rotated. By driving the camera 1 to rotate through the adjusting disk 20, the purpose of focusing and testing the camera 1 is achieved. In the above process, the camera 1 is clamped in the camera fixing hole 10.
[0013] The adjusting disk 20 includes an outer ring wall 30, a connecting disk 40, a tapered disk 50 and a central function table 60. Among them, the outer ring wall 30 is arranged outside the connecting disk 40, and an open cavity 31 is formed by surrounding the inner surface of the outer ring wall 30. In specific implementation, an anti-slip structure 32 is arranged on the outer surface of the outer ring wall 30. The user can act on the anti-slip structure 32 in a pressing and rotating manner with fingers, and then rotate the entire adjusting disk 20. In practice, the anti-slip structure 32 is several anti-slip ribs.
[0014] The tapered disk 50 is arranged inside the connecting disk 40, and the connecting disk 40 is connected between the outer ring wall 30 and the tapered disk 50. In practice, the connecting disk 40 is a horizontal disk body.
[0015] The tapered disk 50 has an inclined inner side surface 51 and an inclined outer side surface 52, and a tapered cavity 53 is formed by surrounding the inclined inner side surface 51 of the tapered disk 50. In practice, the inclined inner side surface 51 and the inclined outer side surface 52 are parallel to each other.
[0016] The central function table 60 is convexly provided at the lower end of the conical disk 50. The camera fixing hole 10 is provided in the central function table 60. The camera fixing hole 10 has a light outlet 11, a card interface 12, and a hole inner wall 13. The hole inner wall 13 is connected between the light outlet 11 and the card interface 12. A hole cavity 14 is formed by surrounding with the hole inner wall 13. The hole cavity 14, the conical cavity 53, and the open cavity 31 communicate with each other to form a light outlet channel.
