Abstract
The utility model relates to a microlens, which comprises a hollow lens cone, a lens and a press ring. The top wall of the hollow lens cone is provided with a through hole while the bottom of the hollow lens cone is run-through, the lens is attached to the inner side of the top wall of the lens cone, the press ring is directly sleeved to the bottom of the lens cone to press and fix the lens, the cross section of the through hole is flared, the thickness of the edge of the lens ranges from 0.75mm to 0.85mm, and convex faces with the sizes matched with the diameter of the bottom end of the through hole are arranged at positions, corresponding to the center of the through hole, on an upper surface and a lower surface of the lens. Preferably, the lens cone is cylindrical, the press ring is a hollow ring, a boss used for being socketed to the inside of the lens cone is arranged on the ring, joints of the lens and the lens cone are bonded through a glue layer, and joints of the lens and the press ring are bonded through a glue layer. The microlens is simple in structure, small in size and stable and reliable, and is favorable for reducing the size of a gastroscope and simplifying structure thereof when used with the gastroscope.
Description
Technical field
The utility model relates to the camera lens technical field, peeps the micro-lens on the gastroscope in being specifically related to be used for.
Background technology
Micro-lens makes the doctor's Direct observation and the diagnosis inside of human body state of an illness become possibility in utilization medically, peeps gastroscope in micro-lens is used for, and makes the doctor more directly perceived and accurate to the diagnosis of gastrointestinal disease.Peep in the cause when gastroscope uses and to stretch into inside of human body, this will cause the subject discomfort sense, so the volume of gastroscope is more little, help the sense of discomfort of reduction of patient more and be convenient to the doctor using, but traditional micro-lens often complex structure, size is big, and the volume of peeping gastroscope in causing is difficult to accomplish minimum.The size of how further to dwindle micro-lens to peep the volume of gastroscope in reducing, is the problem that those skilled in the art need solution badly.
Summary of the invention
In view of this, the technical problems to be solved in the utility model provides a kind of simple in structure, micro-lens that volume is little.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of micro-lens, comprise that roof has the hollow barrel of through hole and bottom perforation, posts the eyeglass on lens barrel roof inboard and is socketed in the trim ring that the effect of compacting fixing len is played in the lens barrel bottom, the xsect of described through hole is " eight " font, described lens periphery thickness is 0.75-0.85mm, and the minute surface up and down of eyeglass is provided with the convex surface of size and through hole bottom diameter coupling corresponding to the center of through hole.
Preferably, above-mentioned lens barrel is preferably cylindrical shape, this be because, the concrete corner angle of columnar lens barrel can not cause wound to organ at inside of human body, cylindrical circular lens barrel helps walking at inside of human body simultaneously.Corresponding to the cylindrical shape lens barrel, described trim ring is the hollow ring, is provided with the boss that is used to be socketed in lens barrel inside above the ring.But according to the actual requirements, lens barrel can also be the semiellipse bodily form or the just polygon bodily form, and the shape of trim ring then should be mated with lens barrel, so that the eyeglass compacting is fixed on lens barrel inside; As further preferred, described hollow ring is a plastic cement hollow ring.
In order to strengthen the steadiness of micro-lens, fit by glue layer in the junction between described eyeglass and the lens barrel.
In order further to strengthen the steadiness of micro-lens, fit by glue layer in the junction between described eyeglass and the trim ring.
Compared with prior art, the utlity model has following advantage:
1, lens barrel through hole xsect of the present utility model is the design of " eight " font, and minute surface is provided with the convex surface of size and through hole bottom diameter coupling corresponding to the center of through hole about eyeglass, utilize " eight " font through hole and convex surface complementation spatially, realization is dwindled the camera lens height, reduces the micro-lens volume.
2, to select peripheral thickness be the eyeglass of 0.75-0.85mm to the utility model, further with the dwindling of camera lens height, reaches the effect of dwindling the micro-lens volume.
3, described trim ring is the hollow ring, and is preferably plastic cement hollow ring, utilizes the elasticity of plastic cement; can effectively protect the eyeglass power that is not impacted to damage; in addition, fitting by glue layer between eyeglass and the lens barrel and the junction between eyeglass and the trim ring, effectively strengthens the steadiness of micro-lens.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is explained in further detail below in conjunction with accompanying drawing and embodiment.
Embodiment 1
As shown in Figure 1, a kind of micro-lens, comprise that roof has the hollow barrel 1 of through hole and bottom perforation, posts the eyeglass 2 on lens barrel roof inboard and is socketed in the trim ring 3 that the effect of compacting fixing len is played in the lens barrel bottom, the xsect of through hole is " eight " font, lens periphery thickness is 0.75mm, and the minute surface up and down of eyeglass is provided with convex surface corresponding to the center of through hole, the size of convex surface is identical with through hole bottom diameter, in the present embodiment, through hole bottom diameter is 0.90mm, and promptly the convex surface diameter on the minute surface is 0.90mm about the eyeglass.
In the present embodiment, lens barrel is a cylindrical shape, and this is that cylindrical circular lens barrel helps walking at inside of human body simultaneously because the not concrete corner angle of columnar lens barrel can not cause wound to organ at inside of human body.Corresponding to the cylindrical shape lens barrel, trim ring is the hollow ring, is provided with the boss that is used to be socketed in lens barrel inside above the ring.In order to strengthen the steadiness of micro-lens, fit by glue layer in the junction between junction between eyeglass and the lens barrel and eyeglass and the trim ring.
Embodiment 2
The micro-lens of present embodiment is substantially the same manner as Example 1, difference is, in the present embodiment, lens periphery thickness is 0.85mm, through hole bottom diameter is 0.95mm, also is that the convex surface diameter on the minute surface is 0.95mm about the eyeglass, and the lens barrel of present embodiment is the semiellipse bodily form in addition, trim ring is selected plastic cement hollow ring for use
The shape of trim ring then should be mated with lens barrel, so that the eyeglass compacting is fixed on lens barrel inside.
The foregoing description is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement also should fall within the protection domain of the present utility model.
