Specific implementation mode

[0023] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] Refer to Figures 1-4 , a new type of three - eye positioning camera, comprising: housing structure 1, micro - lens 2, micro - camera 3, camera fixing bracket with screw 4, mirror and connecting rod structure 5, threaded rod 6, lever 7, spring 8, focusing handle 9, up - and - down displacement screw 10, left - and - right displacement screw 11, liquid crystal shutter 12, power input / signal input / image output connector 13;

[0025] The housing structure 1 has three light - passing holes. The light - passing holes include two large holes and one small hole. The small hole is arranged between the two large holes. Two paths of light pass through the large holes to the liquid crystal shutter 12. After receiving the electrical signal of the device, the liquid crystal shutter 12 instantly turns black to suppress strong light. The suppressed strong light goes to the external microscope to protect the eyes from strong light damage. One path of light passes through the middle small hole, is imaged by the built - in micro - lens, and the optical path is reflected by the mirror to the built - in camera. The camera converts the captured light into an image signal and outputs it to an external display device;

[0026] The micro - lens 2 is snap - fitted to the bottom of the housing structure 1, and the lever 7 is slidably connected to the inner bottom surface of the housing structure 1 through a limit groove;

[0027] Inside the housing structure 1, there is a fixed bracket. A limiting groove is provided on the side of the fixed bracket. The camera fixing bracket with screw 4 is threadedly connected to the limiting groove. The camera fixing bracket with screw 4 restricts the center of the micro camera 3. A lever 7 is fixedly connected to the side of the fixed bracket. A spring groove is provided inside the lever 7. A spring 8 is fixedly connected to the spring groove. A reflecting mirror and a connecting rod structure 5 are fixedly connected between two levers 7. One side of the focusing handle 9 close to the housing structure 1 is fixedly connected with a threaded rod 6. The threaded rod 6 is fixedly connected to one end of the camera fixing bracket with screw 4. The position of the micro camera 3 should be at the focal length of the micro lens 2 to successfully obtain a clear image. After the image is reflected by the reflecting mirror and the connecting rod structure 5, the camera fixing bracket with screw 4 is used to adjust the appropriate distance by rotating the focusing handle 9;

[0028] The focusing handle 9, the up and down displacement screw 10 and the left and right displacement screw 11 are fixedly connected to the outer side of the housing structure 1. The up and down displacement screw 10 and the left and right displacement screw 11 are arranged on both sides of the focusing handle 9. To obtain a precise center position, the lever 7 can be pushed forward and backward by rotating the up and down displacement screw 10 and the left and right displacement screw 11, driving the displacement of the reflecting mirror and the connecting rod structure 5 to change the optical path and thus reach the required position of the image;

[0029] The liquid crystal light shutter 12 is fixedly connected to the upper side of the housing structure 1 through a pressing screw. The power input / signal input / image output connector 13 is fixedly connected and communicated to one side of the housing structure 1 away from the focusing handle 9. To obtain the suppressed light to the externally installed microscope, the external machine needs to give the correct signal to the power input / signal input / image output connector 13 to control the opening and closing of the liquid crystal light shutter 12.

[0030] The functional principle of the present utility model can be described by the following operation method:

[0031] The present utility model adopts the lever principle, combines the pushing and pulling forces of the screw and the spring tension, and can effectively ensure the accuracy of the displacement. When an external force rotates the screw, the thread drives the connecting rod to cooperate with the spring, accurately displacing the image center to the ideal position for object alignment;

[0032] The camera main board inside the present utility model is installed in a fixed plate card slot type, maintaining the rotation of the camera main board caused by external force rotation, and avoiding image distortion and alignment difficulties during the calibration process;

[0033] The present utility model adopts an externally detachable light shutter design. In the case of light shutter damage, the user can remove the four plastic anti-conductive screws fixing the light shutter by himself for replacement, avoiding factory repair.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
