Abstract

The utility model discloses a variable magnification display mechanism for a microscope. The display mechanism comprises an objective changer, a magnification display ring, a magnification display window, a first gear and a second gear, wherein the objective changer is mounted on a changer rotating shaft; a total magnification corresponding to the objective magnification is printed on the surface of the magnification display ring; the magnification display ring is mounted on a magnification display shaft; the first gear is fixed on the magnification display shaft; the second gear is fixed on the objective changer rotating shaft and is meshed with the first gear; and the magnification display window is mounted on the microscope in a conspicuous place corresponding to the magnification display ring. In the utility model, the current total magnification of the microscope is displayed in the conspicuous place in a window form, so that the reading is more visualized and convenient.

Description

Microscopical change shows shows mechanism

Technical field

The utility model relates to the microscope field, relates in particular to a kind of microscopical change and shows and show mechanism.

Background technology

Since microscope has been arranged, people have seen many tiny organisms of can't see in the past and have constituted biological elementary cell---cell.At present, microscope has become people and has been engaged in scientific observation, indispensable aid in research and the bioconversion medium, but existing microscope, be subjected to the restriction of its structural design, enlargement factor for observing object, can only check press back by bowing or be attached in the information of objective lens surface and read, yet, be particular about the high efficiency epoch at this, it is directly perceived inadequately that this kind method seems on the one hand, on the other hand, after microscope length service time, if the press back of its appearance is worn or the attaching thing on surface comes off, especially newly contacts the definite enlargement factor of observing thing of microscopical user will for researchist or experimenter and bring puzzlement, or directly influence the integrality of scientific research information or laboratory report.

Given this, the utility model provides a kind of and has been applied to microscopical change and shows and show mechanism, makes the current total magnification of microscope to show with window form at a full position place, and is more directly perceived by contrast, reads convenient.

The utility model content

The purpose of this utility model is to provide a kind of microscopical change to show to show mechanism, sentences window form in full position and shows the current total magnification of microscope, make read more directly perceived, convenient.

To achieve these goals, the technical solution of the utility model is:

A kind of microscopical change shows shows mechanism, comprises that Nosepiece, multiple show ring, multiple display window and first gear and second gear, and wherein, Nosepiece is installed in the converter rotating shaft; Multiple shows that ring is printed on ring with the corresponding total magnification of object lens multiple for the surface, and multiple shows that ring is installed in multiple and shows on the axle; First gear is fixed on multiple and shows on the axle; Second gear is fixed in the Nosepiece rotating shaft, and is meshing with each other with first gear; The multiple display window is installed on the microscope and shows the corresponding full position of ring with multiple.

Described multiple shows that ring is taper-face ring.

Described second gear and first gear measure-alike, and multiple shows on the annular conical surface that the calibration of object lens mounting hole is identical on the distribute spacing angle and Nosepiece, puts in order on the contrary.

Adopt said structure, the utility model in use, when rotating Nosepiece, second gear is because of being fixed in the converter rotating shaft, the first gear backward rotation with Nosepiece rotation synchronously and drive and its engagement, because of being fixed on multiple, first gear shows on the axle again, first gear promptly shows that by multiple axle drives multiple and shows that ring together rotates, like this, advancing the corresponding total magnification of light path object lens with commentaries on classics promptly shows at display window, it is more directly perceived to allow the user read, convenient.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that multiple of the present utility model shows the ring structure synoptic diagram;

Fig. 3 applies to structural representation on the microscope for the utility model.

Embodiment

As Fig. 1, shown in Figure 3, a kind of microscopical change shows shows mechanism, comprises that Nosepiece 1, multiple show ring 2, multiple display window 3 and first gear 4 and second gear 5, and wherein, Nosepiece 1 is installed in the converter rotating shaft 11; Multiple shows that ring 2 is installed in multiple and shows on the axle 21; In the present embodiment, multiple shows that ring 2 surfaces are the conical surface (also can be anchor ring), be printed on and the corresponding total magnification of object lens multiple (object lens magnification * eyepiece enlargement factor) on multiple demonstration ring 2 conical surfaces, with reference to shown in Figure 2, numeral shows that at multiple the calibration of object lens mounting hole on distribute spacing angle and the Nosepiece 1 on ring 2 conical surfaces 22 is identical, puts in order on the contrary; Multiple display window 3 is installed on the microscope and shows ring 2 corresponding full position with multiple; First gear 4 is fixed on multiple and shows on the axle 21; Second gear 5 is fixed in the converter rotating shaft 11, measure-alike with first gear 4, and be meshing with each other with first gear 4.

When rotating Nosepiece 1, second gear 5 is with first gear, 4 backward rotation of Nosepiece 1 rotation synchronously and drive and its engagement.Because of first gear 4 and second gear 5 identical, so the angle that the angle that second gear 5 turns over and Nosepiece 1 turn over is identical but direction is opposite.First gear 4 is fixed on multiple and shows on the axle 21, therefore can drive multiple and show that axle 21 and multiple show that ring 2 together rotates.Multiple shows that the calibration of object lens mounting hole on digital distribution spacing angle and the Nosepiece 1 on ring 2 conical surfaces 22 is identical again, reversed in order, when Nosepiece 1 rotates, just drive multiple and show that ring 2 rotates synchronously, like this, advancing the corresponding total magnification of light path object lens with commentaries on classics promptly shows at multiple display window 3, it is more directly perceived to allow the user read, convenient.

Need to prove; the dimension scale of first gear 4 and second gear 5, number peace show the surface morphology and the neither restrictions that are subjected to this embodiment such as installation site of multiple display window 3 on microscope of ring 2 in the utility model; the above; it only is a preferred embodiment of the present utility model; all equalizations of doing according to this case design main points change and modify, and all fall in its protection domain.

Claims

1. a microscopical change shows and shows and it is characterized in that mechanism: comprise that Nosepiece, multiple show ring, multiple display window and first gear and second gear, wherein, Nosepiece is installed in the converter rotating shaft; Multiple shows that ring is printed on ring with the corresponding total magnification of object lens multiple for the surface, and multiple shows that ring is installed in multiple and shows on the axle; First gear is fixed on multiple and shows on the axle; Second gear is fixed in the Nosepiece rotating shaft, and is meshing with each other with first gear; The multiple display window is installed on the microscope and shows the corresponding full position of ring with multiple.
