The utility model provides a mechanism for providing a biological shutter 3D image by improving the structure, which comprises the following technical scheme:

as shown in fig. 1 and 2, a mechanism for providing a biological shutter 3D image, comprising: a microscope 1, an imaging assembly 2, a rotation assembly 3, and a height adjustment assembly 4.

The imaging assembly 2 images a sample under the microscope 1. In some embodiments, the imaging assembly 2 may be a camera for taking a picture of a sample under the microscope 1.

As shown in fig. 3, the rotating assembly 3 includes a fixed block 31, a rotation driving device 32 and a rotating shaft 33, the fixed block 31 is fixedly arranged on the microscope 1, the rotation driving device 32 is fixed on the fixed block 31, the rotating shaft 33 passes through the fixed block 31, and the rotation driving device 32 is in transmission connection with the rotating shaft 33. In some embodiments, the rotation driving device 32 may be a micro brushless servo motor, and the rotation driving device 32 may also be other devices known to those skilled in the art, such as a rotary cylinder, etc., which is not limited herein.

As shown in fig. 4, the height adjusting assembly 4 includes a lifting plate 41 and a lifting driving device 42, the lifting driving device 42 is fixedly connected with the rotating shaft 33, and the lifting driving device 42 is in transmission connection with the lifting plate 41.

As shown in fig. 3, the rotating assembly 3 further includes a worm wheel 34 and a worm 35, the worm wheel 34 is connected with the fixed block 31 through a first bearing 36, the worm wheel 34 is fixedly connected with the rotating shaft 33, the worm 35 is connected with the fixed block 31 through a second bearing 37, the worm 35 is fixedly connected with the rotation driving device 32, and the worm 35 is meshed with the worm wheel 34.

When the rotation angle is adjusted, the rotation driving device 32 in the rotation assembly 3 drives the worm 35, the worm wheel 34 and the rotation shaft 33 to rotate in sequence, and the rotation shaft 33 drives the height adjusting assembly 4 and the glass slide positioned on the height adjusting assembly 4 to rotate.

The end of the rotating shaft 33 away from the fixed block 31 is provided with a mounting table 331. The rotating shaft 33 is provided with a limiting notch 332, the fixed block 31 is connected with a knob 38 in a threaded manner, and the knob 38 is matched with the limiting notch 332 to limit. When the 3D technique is not needed for drawing or the microscope 1 is not needed, the knob 38 can be screwed into the mounting table 331, so that the knob 38 is inserted into the limiting notch 332 for limiting, and the parts of the rotating assembly 3 are prevented from being displaced due to shaking and vibration.

As shown in fig. 4, the height adjusting assembly 4 further includes a screw 43 and a rotary tray 44, the rotary tray 44 is fixed on the mounting table 331, the screw 43 passes through the rotary tray 44 and is connected with the rotary tray through a third bearing 45, the lifting driving device 42 is a roller, the roller is fixedly connected with the upper end of the screw 43, the lifting plate 41 is provided with a connecting lug 411, and the connecting lug 411 is in threaded connection with the screw 43.

The roller is fixedly connected with the screw 43, and the screw 43 is in threaded connection with the connecting lug 411 of the lifting plate 41. When the height is adjusted, the screw 43 is driven to rotate when the roller rotates, and the screw 43 is in threaded connection with the connecting lug 411 of the lifting plate 41. At this time, the lifting plate 41 is lifted or lowered along with the rotation of the screw, and the height adjustment of the lifting plate 41 is sequentially achieved.

It will be readily appreciated that since the rotating tray 44 of the height adjustment structure is screwed onto the rotating shaft 33 of the rotating assembly 3, the height adjustment assembly 4 will vary with the angle produced by the rotating assembly 3. The slide must be viewed on the microscope 1 on the axis of rotation 33 of the rotating assembly 3, but the slide is not exactly identical in size, and a height adjustment mechanism is required to adjust the slide to the axis of rotation 33 so that the slide view is coplanar with the axis of rotation 33.

When the device is used, after a glass slide is placed, an observation object of the glass slide is adjusted to be coplanar with the rotating shaft 33, the motor rotates, the rotating shaft 33 of the rotating assembly 3 rotates along with the observation object, so that the angle required by the lifting plate 41 of the height adjusting assembly 4 is obtained, the lifting plate 41 of the height adjusting assembly 4 rotates forward by a certain angle, then a photo is taken by the camera, and the lifting plate 41 of the height adjusting assembly 4 rotates reversely by the same angle, and then the camera takes a photo again. Thus, two sets of images having a phase difference are captured. The two pictures can be fused into a 3D picture through the current shutter 3D technology, and more details than the 2D picture can be seen. The value of the microscope 1 is improved.

As shown in fig. 4, a guide assembly is disposed on a side of the rotating tray 44 near the lifting plate 41, and the lifting plate 41 is slidably connected with the guide assembly. The guide assembly comprises a plurality of guide posts 51 and guide sleeves 52. The guide sleeve 52 is a ball copper sleeve. The guide post 51 and the guide sleeve 52 in the guide assembly serve as positioning and guiding functions. The guide post 51 may be made of metal. The guide sleeve 52 mates with the guide post 51 and provides an inner diameter to accommodate the guide post 51. The guide sleeve 52 serves to guide the movement of the guide post 51 so that the lifting plate 41 can be accurately positioned and moved under the guide of the guide post 51. The guide sleeve 52 also serves to reduce friction and wear and to increase the service life of the guide post 51. The ball copper sleeve is adopted as the guide sleeve 52, and has high hardness, excellent wear resistance, difficult seizure phenomenon, good casting performance and cutting processability, and good corrosion resistance in the atmosphere and fresh water.

As shown in fig. 4, the lifting plate 41 is provided with a light hole 412. The light holes 412 function to control the manner in which light enters and passes through the sample. It can adjust the intensity and direction of light so that the light can properly impinge on the sample and return through the sample into the eyepiece for viewing and magnifying the details of the sample.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
