Description
Technical field
The present invention relates to medical instrument more particularly to adjustable endoscope lens groups.
Background technique
Endoscope is a pipe equipped with light, it can be entered in stomach with direct oral cavity or be entered through other natural holes
In vivo.Using endoscope it can be seen that the lesion that X-ray cannot be shown, therefore it is highly useful to doctor.For example, being peeped by interior
Mirror doctor can observe ulcer or tumour in stomach, make optimal therapeutic scheme accordingly.
In the prior art, endoscope is all made of grin lens, but grin lens have imaging compared with optical lens
It is of poor quality, field angle is small, unadjustable, reduce accuracy.
Summary of the invention
The present invention facilitates adjustable in view of the above problems, to provide a kind of structure simple, and the one kind for improving imaging reliability can
Mode endoscope lens group.
The technical scheme is that including cylinder-shaped microscope base, it is successively arranged protection glass in the microscope base, diaphragm, puts down
Convex lens and lens, the protection glass are connected with diaphragm gluing, and spacing is equipped between the plano-convex lens and lens, described flat
The convex surface of convex lens and the interior convex surface of lens are oppositely arranged；The side wall of the microscope base is equipped with a pair of translot arranged symmetrically, the cross
Slot includes the through slot and accommodation groove of connection,
The diaphragm is equipped with positioning column towards the side of planar convex lens, and the plane of the planar convex lens is equipped with a pair of of positioning
Slot, the positioning column one-to-one correspondence are located in locating slot,
The both ends of the planar convex lens are respectively equipped with sliding block, and the sliding block one-to-one correspondence is located in accommodation groove, in the through slot
Equipped with for pushing the push rod of sliding block.
The external port of the through slot is equipped with blocking, and the section of the blocking is T-shaped.
The positioning column is glass column.
The positioning column is connected by glue on diaphragm.
The outer end face of the lens is plane, convex surface or concave surface.
It is successively arranged protection glass, diaphragm, plano-convex lens and lens in microscope base in the present invention, protects glass and diaphragm glue
It is connected, diaphragm improves the quality of imaging and the shading value of control picture；Pass through positioning column between diaphragm and plano-convex lens and determines
The type of attachment of position slot, facilitates the two to position；Sliding block is arranged in the both ends of plano-convex lens, by push rod band movable slider, to drive
Plano-convex lens are mobile, so that the distance between plano-convex lens and lens are adjustable, under the premise of guaranteeing imaging clearly, improve imaging
Quality.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention,
Fig. 2 is the partial enlarged view in Fig. 1 at A；
1 is microscope base in figure, and 2 be protection glass, and 3 be diaphragm, and 4 be plano-convex lens, and 5 be lens, and 6 be translot, and 61 be through slot, and 62 are
Accommodation groove, 7 be positioning column, and 8 be locating slot, and 9 be sliding block, and 10 be push rod, and 11 be blocking.
Specific embodiment
The present invention is as shown in Figs. 1-2, including cylinder-shaped microscope base 1, be successively arranged in the microscope base protection glass 2, diaphragm 3,
Plano-convex lens 4 and lens 5, the protection glass are connected with diaphragm gluing, and spacing, institute are equipped between the plano-convex lens and lens
The interior convex surface on the convex surface and lens of stating plano-convex lens is oppositely arranged；The side wall of the microscope base is equipped with a pair of translot 6 arranged symmetrically, institute
The through slot 61 and accommodation groove 62 that translot includes connection are stated,
The diaphragm is equipped with positioning column 7 towards the side of planar convex lens, and the plane of the planar convex lens is equipped with a pair of of positioning
Slot 8, the positioning column one-to-one correspondence are located in locating slot,
The both ends of the planar convex lens are respectively equipped with sliding block 9, and the sliding block one-to-one correspondence is located in accommodation groove, in the through slot
Equipped with for pushing the push rod 10 of sliding block.Push rod is arranged in through slot, can be pushed pin by setting and carry out push pull maneuver, movement can
It leans on.
It is successively arranged protection glass, diaphragm, plano-convex lens and lens in microscope base in the present invention, protects glass and diaphragm glue
It is connected, diaphragm improves the quality of imaging and the shading value of control picture；Pass through positioning column between diaphragm and plano-convex lens and determines
The type of attachment of position slot, facilitates the two to position；Sliding block is arranged in the both ends of plano-convex lens, by push rod band movable slider, to drive
Plano-convex lens are mobile, so that the distance between plano-convex lens and lens are adjustable, under the premise of guaranteeing imaging clearly, improve imaging
Quality.
The outer end face of lens can couple, group with image guide bundles, optical inversion system or electronics sensor devices (CCD, CMOS etc.)
At soft, rigid or fujinon electronic video endoscope.Field angle of the present invention is big, easy to process and image quality is high.
The external port of the through slot is equipped with blocking 11, and the section of the blocking is T-shaped, and T shape is easy to disassemble.
Blocking is set, convenient for closing to through slot, improves airtightness.
The positioning column 7 is glass column.It is located by connecting reliable, guarantees that imaging is reliable.
The positioning column is connected by glue on diaphragm.Facilitate processing, connection is reliable.
The outer end face of the lens is plane, convex surface or concave surface.Convenient for carrying out selection setting according to need of work.
The push rod and sliding block are connected by glue, and are convenient for through push rod band movable slider sweeping action, thus, so that plano-convex
Lens move back and forth, the spacing being conveniently adjusted between plano-convex lens and lens.
