Abstract

The utility model provides a portable three-purpose mirror which comprises an objective lens group, a middle lens group, an eye lens group and a microscope supporting seat, wherein, an eye lens cylinder of the eye lens group is provided with three notches which are evenly distributed on the circle; an opening part of the eye lens cylinder is provided with a circuit of edge which is outwards convex; the outer diameter of the eye lens cylinder is little larger than the inside diameter of the middle lens group; the eye lens group is made of precise engineering plastic. The eye lens cylinder can smartly glide corresponding to the middle lens group, can also be reliably adjusted and fixed on a position, and a microscope bracket used for supporting a microscope main body part is made of transparent engineering plastic and is provided with a gap at the same time for satisfying the lighting needed by watchinh.

Description

Portable three-purpose mirror

The utility model relates to a kind of optical instrument, refers in particular to a kind of portable three-purpose mirror.

Integrate at present look in the distance, amplification, micro-three-purpose mirror all adopt existing technical combinations to form, and the focusing mode of optical devices has being slidingly matched of metalwork lens barrel (object lens, eyepiece two lens barrels) (tolerance fit a kind of) and threaded adjusting etc. in the existing technology; The light source of microscope part adopts band lamp source or not with the mirror reflects mode in lamp source etc.Said method exists the machining precision height, amount of parts is many, the cost of raw material is big, structure is complicated, volume is bigger than normal, deficiencies such as convenience are owed in operation.

The purpose of this utility model is to provide a kind of can adjust focus more easily, can use the portable three-purpose mirror of its micro-function simultaneously under physical environment.

The purpose of this utility model can be achieved through the following technical solutions: a kind of portable three-purpose mirror, comprise objective lens, central lens group and eyepiece group and microscope bearing, wherein leave three notches that are evenly distributed on the circumference on the eyepiece stalk of eyepiece group, and the limit of one circle to outer lug arranged in the port part of eyepiece stalk, its external diameter is slightly larger than the internal diameter of central lens group, eyepiece stalk is made by the precision engineering plastics and is had certain elasticity, so eyepiece is assembled into after the central lens group, just has certain friction between eyepiece stalk and the central lens group.

Simultaneously, being used for supporting microscope body microscope stand partly is to make and open a breach with transparent engineering plastics, the microscope stand inner chamber is separated in establishing, the two flanges on same horizontal line, and its distance to the lower end has certain requirement, is the locating surface of the distance of microscope object space.

Adopt technique scheme, the eyepiece stalk of this three-purpose mirror can be set up on a certain position again so that watch in central lens group reliably in flexible slip, its notched transparent microscope stand can illuminate the observing object surface by natural light to be convenient to observe, and bracket flange can accurately be located microscope body.

Below by drawings and Examples the utility model is further specified:

Fig. 1 is the cutaway view Amplified image that the utility model is combined;

Fig. 2 is the stereographic map of eyepiece group of the present utility model;

Fig. 3 is a microscope stand cut-open view of the present utility model;

Fig. 4 is a microscope stand stereographic map of the present utility model;

Fig. 5 is 2.5 times of telescope constitutional diagrams of the present utility model;

Fig. 6 is 15 times of magnifier constitutional diagrams of the present utility model;

Referring to accompanying drawing 1, eyepiece frame 1, eyepiece 6, eyepiece mount 2 is formed the eyepiece group, intermediate lens frame 3, intermediate lens 7, intermediate lens trim ring 31 is formed central lens group, object lens trim ring 41, object lens frame 4, object lens 8 are formed objective lens, wherein leave three long rabbets (referring to Fig. 2) that are evenly distributed on the circumference on the eyepiece stalk of eyepiece mount 2, port part at eyepiece stalk has the limit of a circle to outer lug, its external diameter is slightly larger than the internal diameter of central lens group, eyepiece stalk is made by the precision engineering plastics and is had certain elasticity, so eyepiece is assembled into after the central lens group, have certain friction between eyepiece stalk and the central lens group, the eyepiece stalk of this three-purpose mirror can be set up on a certain position so that watch again in central lens group reliably in flexible slip.

Referring to Fig. 3 and Fig. 4, microscope stand 5 is made by transparent engineering plastics, and has breach, can illuminate the observing object surface so that observe by natural light.The inner chamber of microscope stand 5 is separated in establishing, be in two protruding Edge on the same horizontal line, then can make microscope body can be put into the position accurately and quickly.

Referring to Fig. 5, being linked together by eyepiece group and central lens group has the function of looking in the distance, and is adjusted to shown position by sliding push-pull eyepiece group, and enlargement ratio is 2.5 times.If the relative position of eyepiece group and central lens group is adjusted to eyepiece apart from object lens position farthest, its enlargement ratio is 3 times.

Referring to Fig. 6, enlarging function of the present utility model is by different mirror groups and combination thereof and have different enlargement ratios.Wherein the enlargement ratio of single central lens group is 5 times; The enlargement ratio of single objective lens is 10 times; The enlargement ratio that central lens group, objective lens and microscope stand 5 are combined into shown position is 15 times, and wherein microscope stand 5 bottoms upwards are inserted into protruding Edge place for central lens group and objective lens.

The combination of eyepiece group, central lens group, objective lens and microscope stand 5 has micro-function.Enlargement ratio is 25 times when the utility model makes up and is adjusted to state shown in Figure 1; Micro-enlargement ratio is 30 times when making 22 millimeters on objective lens tip-to-face distance observing object surface when the microscope body in the utility model combination inserts and is adjusted to from the other end of microscope stand 5 by shown position.

Claims

1, a kind of portable three-purpose mirror, comprise by eyepiece frame, eyepiece, the eyepiece group that eyepiece mount is formed, by the intermediate lens frame, intermediate lens, the central lens group that the intermediate lens trim ring is formed, objective lens, central lens group and eyepiece group and microscope stand, it is characterized in that: leave three notches that are evenly distributed on the circumference on the eyepiece stalk of wherein said eyepiece mount, the port part of described eyepiece stalk has the limit of a circle to outer lug, its external diameter is slightly larger than the internal diameter of described central lens group, described eyepiece stalk is made by the precision engineering plastics and is had certain elasticity, and the described microscope stand that is used for supporting the microscope body part is with transparent engineering plastics making and opens a breach.
