Description

Reading microscope with LED light source

Technical Field

The utility model belongs to the technical field of measuring tools, and particularly relates to a reading microscope with an LED light source.

Background

After the heat treatment process of the parts, it is necessary to check the hardness of the parts by a reading microscope, which is commonly used, and when checking the hardness of the parts, it is necessary to face an illumination lamp equipped with a moving light source or a fixed light source, or to check the hardness of the parts by means of the brightness of natural light. The light source, an eyepiece of the reading microscope, an objective lens and the inspected part are not on the same axis, so that reflection is easy to generate, the inspection effect is affected, and a certain amount of deviation is generated.

In order to remove the influence of the reflection of the illumination lamp and natural light on the inspection effect of the reading microscope, and also to solve the problem that the illumination lamp provided with a movable light source or a fixed light source is not convenient enough in use, the illumination device of the reading microscope needs to be studied.

Disclosure of Invention

Aiming at the problems, the inventor provides a reading microscope with an LED light source through repeated exploration and research, and aims to integrate the light source with a microscope base, avoid the trouble of additionally carrying a lighting lamp, avoid the occurrence of reflection and greatly improve the measurement efficiency and the measurement precision.

In order to achieve the purpose, the technical scheme adopted by the utility model is that the reading microscope with the LED light source is designed and comprises a lens tube and a circular ring-shaped base, wherein the circular ring-shaped base is arranged at the lower end of the lens tube; the LED lamp is characterized in that a power switch and a button cell are arranged on the outer wall of the lens tube, two LED lamps are arranged on the inner wall of the annular base, and the two LED lamps are connected in parallel and then connected in series with the power switch and the button cell to form a complete power lighting loop.

Further, the power switch and the button cell are symmetrically arranged along the lens tube.

Further, the number of the button cells is two, the specification is 2032, and the voltage is 3V.

Further, the two LED lamps are symmetrically arranged along the center of the annular base.

The beneficial effects of the utility model are as follows: the light source and the microscope base are integrated together, the trouble of additionally carrying the lighting lamp is avoided, the light reflection is avoided when the lighting lamp and the measurement lamp are arranged on the same axis, and the measurement efficiency and the measurement accuracy are greatly improved.
