Description

Technical Field

[0001] The present invention relates to the field of microscope technology, and in particular to a stereo microscope for producing and processing orthokeratology lenses. Background Art

[0002] Orthokeratology lenses are common devices in life and are an effective method for treating myopia. Their quality needs to be tested during their production process. People now generally observe orthokeratology lenses through stereo microscopes. Stereo microscopes, also known as solid microscopes, are binocular microscopes that give both eyes a stereoscopic sense. The observation object does not need to be processed or made, and can be directly placed under the lens with lighting for observation. The imaging is upright, which is convenient for operation and dissection. The field of view has a large diameter, but the magnification of the observed object is required to be less than 200 times. The current stereo microscopes used for the production and processing of orthokeratology lenses generally protect the lens barrel with a threaded cap during use to prevent dust from adhering to the lens, resulting in unclear detection results. However, current microscopes are prone to the problem of losing the threaded cap after use, which causes the lens barrel to be eroded by dust, reducing the detection efficiency of the device. In dim light conditions, the slide needs to be illuminated for imaging and observation. Therefore, we propose a stereo microscope for the production and processing of orthokeratology lenses. Summary of the invention

Adjust the focusing nut, and the rotation of the focusing nut drives the threaded rod to rotate. Since the threaded plate is threadedly connected to the threaded rod, the threaded plate moves downward, driving the focusing bracket to move downward, and then driving the observation head to approach the slide for observation; a clamping mechanism is provided on the top of the base, and the clamping mechanism includes a shoulder screw, which is symmetrically arranged on the top of the base, and two of the shoulder screws are fixedly connected to the top of the base. The outer surface of the shoulder screw is rotatably connected to a slide clamp, and a focusing component is provided at the interval between the two slide clamps. The slide is placed above the focusing component, and the focusing component increases the brightness of the bottom of the slide, thereby improving the observation effect of the stereo microscope, and the spring of the shoulder screw drives the slide clamp to clamp the slide.

[0004] Furthermore, the dust-proof component includes a limit groove, which is arranged on a side of the focusing bracket close to the observation head, and a card slot is also provided on a side of the focusing bracket away from the base, the inner wall of the limit groove is slidably connected with a card plate, and the card plate is fixedly connected to the outer surface of the vertical rod, and the card plate is adapted to the card slot, and the card plate slides on the inner wall of the limit groove, so that when the focusing bracket slides on the surface of the vertical rod driven by the focusing mechanism, the card plate limits the focusing bracket to avoid twisting when the focusing bracket slides, and when the card plate is inserted into the card slot, the observation head is just suspended on the top of the slide clamp to avoid damage to the slide and the objective lens caused by contact between the objective lens and the slide.

[0005] Furthermore, one end of the card plate close to the observation head is fixedly connected to a ring plate, and the ring plate is arranged outside the observation head. The inner wall of the ring plate is fixedly connected to a dust-proof curtain, and the end of the dust-proof curtain away from the observation head is elastic. Several dust-proof curtains are arranged along the circumference of the ring plate, and the ends of several dust-proof curtains away from the ring plate are fixedly connected to each other, and the dust-proof curtain is slidably connected to the outer surface of the observation head. The focusing bracket moves downward, and the dust-proof curtain slides on the surface of the observation head. Several dust-proof curtains open to each other, so that the objective lens at the bottom of the observation head leaks out, so that the slide can be observed. The dust-proof curtain is set and opened only when observation is needed, thereby ensuring that the dust-proof curtain blocks dust when the objective lens is not in use, thereby avoiding the objective lens from being contaminated and reducing the observation effect.

[0006] Furthermore, an airbag wall is fixedly connected to the inner side of the dust-proof curtain, and the airbag wall is arranged at the bottom of the observation head. Air holes are opened on the surface of the airbag wall, and the air holes are inclined and arranged toward the observation head. The dust-proof curtains are opened to each other, so that the airbag wall contracts, and the air holes arranged obliquely upward spray out the gas inside the airbag wall, further brushing off the dust on the surface of the objective lens, thereby further improving the observation effect of the objective lens.

[0007] Furthermore, a hook plate is provided inside the air hole, and a plurality of the hook plates are provided along the circumference of the air hole. The hook plate is fixedly connected to the inner wall of the air hole. When the airbag wall recovers after being compressed, the airbag wall inhales air, and while inhaling air, the floating dust and flocculent impurities in the air are blocked by the hook plate to prevent the floating dust and flocculent impurities from being inhaled, causing the impurities to be carried in the airflow ejected from the air hole when the airbag wall is compressed, thereby preventing the impurities from adhering to the surface of the objective lens and affecting the imaging.

[0008] Furthermore, a hair-sticking plate is provided at the interval between the airbag wall and the dust-proof curtain, the hair-sticking plate is fixedly connected to the side of the dust-proof curtain close to the airbag wall, the hair-sticking plate is fixedly connected to the side of the airbag wall close to the hair-sticking plate, and the side of the connecting plate away from the hair-sticking plate is fixedly connected to a hair-sticking block, so that floating dust and flocculent impurities are sucked into the air holes, and the hair-sticking blocks adhere to the impurities, thereby further avoiding impurities being carried in the airflow ejected from the air holes when the airbag wall is compressed, thereby further improving the imaging effect.

[0009] Furthermore, the clamping mechanism also includes a fixing plate, which is fixedly connected to the side of the two slide clamps away from each other, and the side of the base close to the slide clamp is symmetrically provided with arc grooves, and the insides of the two arc grooves are slidably connected with sliding rods, and the side of the base close to the arc groove is also provided with a spring plate, and the two ends of the spring plate are respectively fixedly connected to the side of the two fixing plates away from each other, and the side of the sliding rod away from the base passes through the spring plate and extends above it, and a fixing column is fixedly connected to the center of the outer surface of the spring plate, and the fixing column It is fixedly connected to the outer surface of the base, and the two sliding rods are moved. The sliding rods slide inside the arc groove, and the spring plate is deformed, driving the two fixed plates to move away from each other. The fixed plates move away from each other and drive the slide clamp to open. The sliding rod is released, and the slide clamp clamps the slide under the elastic force of the spring plate and the spring force of the shoulder screw. The spring of the spring plate assists the shoulder screw to provide elastic force for the slide clamp to clamp the material, thereby avoiding fatigue damage of the shoulder screw after long-term use. The sliding rod is set to slide inside the arc groove to limit the deformation of the spring plate and avoid damage caused by excessive stretching of the spring plate.

[0010] Further, the focusing assembly includes a groove plate, the groove plate is arranged at the interval between the two slide clamps, the groove plate is fixedly connected to the side of the base close to the slide clamp, the inner wall of the groove plate is slidably connected with a light-transmitting plate, the side of the base close to the slide clamp is also provided with a receiving groove, and the receiving groove is provided directly below the light-transmitting plate, the inner wall of the receiving groove is fixedly connected with a diffuser plate, the diffuser plate is arranged in a concave lens shape, the side of the receiving groove away from the diffuser plate is provided with a bottom plate, and the bottom plate is far from the base The diffuser is fixedly connected to one side of the slide holder, an LED lamp is arranged at the interval between the diffuser and the bottom plate, and the LED lamp is fixedly connected to one side of the bottom plate close to the diffuser. A refraction component is also arranged inside the accommodating groove, and the LED lamp emits light, and the light passes through the diffuser. Since the diffuser is arranged in a concave lens shape, the diffuser scatters the light to the bottom of the light-transmitting plate, so that the slide on the top of the light-transmitting plate is evenly irradiated with light, so that the image brightness of the slide inside the eyepiece of the observation head is clear and uniform.

[0011] Furthermore, the refraction assembly includes a fixed seat, which is fixedly connected to the inner wall of the receiving groove, and a plurality of the fixed seats are evenly arranged inside the receiving groove, a refraction plate is fixedly connected to the side of the fixed seat away from the inner wall of the receiving groove, and the refraction plate is inclined toward the diffuser plate, and a reflection plate is fixedly connected to the bottom of the refraction plate away from the fixed seat, and the reflection plate is set to a concave surface, the refraction plate refracts the light irradiated to the inner wall of the receiving groove, so that the light emitted by the LED lamp fully illuminates the bottom of the glass slide, thereby making the imaging clearer and brighter, and by arranging a concave mirror-shaped reflection plate at the bottom of the refraction plate away from the fixed seat, the light reflected by the reflection plate is converged and illuminated on the outer circle of the glass slide, so that the center brightness of the glass slide is basically the same as the outer circle, further making the imaging brightness uniform.

[0012] The present invention has the beneficial effects: The present invention provides a dustproof component, the focusing bracket moves downward, the dustproof curtain slides on the surface of the observation head, and a plurality of dustproof curtains are opened to each other, so that the objective lens at the bottom of the observation head leaks out, so that the slide can be observed. The dustproof curtain is provided and opened only when observation is required, thereby ensuring that the dustproof curtain blocks dust when the objective lens is not in use, and preventing the objective lens from being contaminated and causing a reduction in the observation effect.

[0013] The present invention arranges air holes. When the airbag wall recovers after being compressed, the airbag wall absorbs air. While absorbing air, floating dust and flocculent impurities in the air are drawn in. The hook plate blocks the impurities to prevent the floating dust and flocculent impurities from being drawn in. As a result, when the airbag wall is compressed, the airflow ejected from the airhole carries impurities. This prevents the impurities from adhering to the surface of the objective lens and affecting imaging. The airbag absorbs floating dust and flocculent impurities, and the sticky hair block adheres to the impurities. This further prevents the airflow ejected from the airhole from carrying impurities when the airbag wall is compressed, thereby further improving the imaging effect.

[0014] The present invention sets a diffuser plate, and the LED lamp emits light, and the light passes through the diffuser plate. Since the diffuser plate is set in a concave lens shape, the diffuser plate scatters the light evenly to the bottom of the light-transmitting plate, so that the glass slide on the top of the light-transmitting plate is evenly irradiated by the light, so that the image brightness of the glass slide inside the eyepiece of the observation head is clear and uniform.

[0015] The present invention provides a deflecting plate, which refracts the light irradiated to the inner wall of the receiving groove, so that the light emitted by the LED lamp can fully illuminate the bottom of the glass slide, thereby making the image clearer and brighter. By providing a reflector in the shape of a concave mirror at the bottom of the deflecting plate away from the fixed seat, the light reflected by the reflector is focused and illuminated on the outer circle of the glass slide, so that the brightness of the center of the glass slide is basically the same as that of the outer circle, thereby further making the imaging brightness uniform.
