[0001] This utility model relates to the field of camera technology, specifically to a deflection axis refocusing mechanism for a hollow fiber optic fusion splicer camera. Background Technology

[0002] The specification of the existing camera mechanism and electronic device (publication number CN214045795U) mentions "a movable part, which is disposed on the display end of the electronic device and can move along the side of the display end; a camera body, which is mounted on the movable part; a hook, which is pivotally connected to the movable part by a torsion spring; a slot, which is formed on the display end, and the hook can be hooked to the slot or dragged with the slot by pivoting; a spring, which is used to apply force to the movable part in a direction away from the slot". However, the existing technology cannot control the rotation angle and extension / retraction distance of the camera, makes it difficult to adjust the focus, and is not flexible and practical. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a bias-axis refocusing mechanism for a camera in a hollow fiber fusion splicer is provided. This mechanism addresses the problems of existing technologies being unable to control the camera's rotation angle and extension / retraction distance, making it difficult to adjust the focal length and lacking flexibility and practicality.

[0004] To achieve the above objectives, a deflection axis refocusing mechanism for a camera in a hollow fiber fusion splicer is provided, comprising a base, a camera, and a motor. A notch is provided in the middle of the upper end face of the base. Side mounting plates are provided on both the left and right sides of the base, and two sets of motors are mounted on the side mounting plates. A fixing sleeve is provided at the bottom of the motor and is fixed to the side mounting plate. A rotating shaft is mounted at the front end of the motor, and a camera is mounted above the motor.

[0005] Furthermore, the front part of the rotating shaft is fitted with a front sleeve plate, and the front sleeve plate is narrow in the middle and wide on both sides.

[0006] Furthermore, both the pivot and the front sleeve are flip-up structures, and the two sets of cameras on the left and right sides above the base are arranged in a relatively movable manner.

[0007] Furthermore, side fixing plates are fixed to both the left and right ends of the front sleeve plate, and an upper sleeve plate is fixed to the upper end of the side fixing plate, and the upper sleeve plate is fixed outside the middle fixing plate.

[0008] Furthermore, the middle fixed plate contains multiple sets of telescopic cylinders, and the upper end of the telescopic cylinders is fixed under the upper mounting frame, which is movable and can be raised and lowered.

[0009] Furthermore, the camera is housed in the upper mounting bracket, and the upper mounting bracket adopts a rectangular sleeve structure.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model utilizes the telescopic movement of a telescopic cylinder to appropriately raise the height of the camera, allowing for flexible up-and-down movement of the camera. Furthermore, the cameras on the left and right sides can perform relative shooting movements, making the offset focus adjustment more flexible and stable.

[0012] 2. Compared with directly fixing the camera to the telescopic cylinder, this utility model, which places the camera inside the upper mounting bracket, is safer and more stable, and also provides protection for the outer side.

[0013] 3. Simultaneously, using the Y-axis as the center line, the motor rotates the shaft, and the shaft and front cover are flipped appropriately to control the rotation direction and position of the camera. Attached Figure Description

[0022] Reference Figures 1 to 4 As shown, this utility model provides a deflection axis refocusing mechanism for a camera in a hollow fiber fusion splicer, including a base 1, a camera 2, and a motor 3. A notch 10 is provided in the middle of the upper end face of the base 1. Side mounting plates 11 are provided on both the left and right sides of the base 1, and two sets of motors 3 are mounted on the side mounting plates 11. A fixing sleeve 30 is provided at the bottom of the motor 3 and the fixing sleeve 30 is fixed on the side mounting plate 11. A rotating shaft 31 is installed at the front end of the motor 3, and the camera 2 is installed above the motor 3.

[0023] In this embodiment, the front part of the rotating shaft 31 is fitted with a front sleeve plate 32, and the front sleeve plate 32 is narrow in the middle and wide on both sides; both the rotating shaft 31 and the front sleeve plate 32 are flip-up structures, and the two sets of cameras 2 on the left and right sides above the base 1 are arranged in a relatively movable manner.

[0024] As a preferred embodiment, this utility model utilizes the telescopic cylinder 36 to extend and retract, which can appropriately raise the height of the camera 2, allowing the camera 2 to move up and down flexibly. Meanwhile, the cameras 2 on the left and right sides can perform relative imaging activities, making the offset focus adjustment more flexible and stable.

[0025] In this embodiment, side fixing plates 33 are fixed at both ends of the front sleeve plate 32, and an upper sleeve plate 34 is fixed at the upper end of the side fixing plate 33. The upper sleeve plate 34 is fixed outside the middle fixing plate 35. Multiple sets of telescopic cylinders 36 are fitted in the middle fixing plate 35, and the upper end of the telescopic cylinder 36 is fixed under the upper mounting frame 37. The upper mounting frame 37 can be raised and lowered.

[0026] As a preferred embodiment, the present invention places the camera 2 inside the upper mounting bracket 37, which is safer and more stable than fixing the camera 2 directly to the telescopic cylinder, and also provides protection for the outer side.

[0027] Simultaneously, with the Y-axis as the center line, the motor 3 rotates the shaft 31, and the shaft 31 and the front sleeve 32 are flipped appropriately, thereby controlling the rotation direction and position of the camera.

[0028] This invention effectively solves the problems of existing technologies that cannot control the rotation angle and extension / retraction distance of the camera, making it difficult to adjust the focal length and lacking flexibility and practicality.

Moreover, the cameras on the left and right sides can perform relative imaging activities, and the bias axis-off focus adjustment is more flexible, stable, safe, stable, flexible and practical.
