Embodiment 1

[0031] Such as Figure 1-5 As shown, the present invention provides a microscope lens magnification switching device, comprising a microscope body 1, a support frame 2 and a lens barrel 3, the top of the microscope body 1 is rotationally connected with the bottom of the support frame 2, and the lens barrel 3 is positioned at the bottom of the support frame 2 Set on the right side, the outer wall of the lens barrel 3 is clamped with an adjustment ring 4, the outer wall of the adjustment ring 4 is slidingly connected with the outer wall of the support frame 2, the lens adjustment device 5 is arranged under the bottom of the lens barrel 3, and the outer wall of the support frame 2 is fixed and installed There is a pulley bar 6, and the outer wall of the pulley bar 6 is fixedly equipped with a clamping device 7. In order to adjust the position of the adjusting ring 4, the clamping device 7 can change the distance between the lens barrel 3 and the microscope body 1, so as to adapt t...

Embodiment 2

[0035] Such as Figure 1-5 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, one side of the elastic member 13 is provided with a support column 14, and the top of the support column 14 is fixedly connected to the bottom of the bearing plate 12, and the support column The outer wall of 14 is embedded with a T-shaped tube 23. When the carrier plate 12 moves down, it will drive the carrier plate 12 to move down, so that the support column 14 enters the inside of the T-shaped tube 23, resulting in a reduction in the internal space of the T-shaped tube 23. Air pressure increases, and the inner wall of T-shaped pipe 23 is slidably connected with movable plate 22, and the top of movable plate 22 is fixedly connected with pop-up piece 8, and the outer wall of pop-up piece 8 is slidably connected with the inner wall of support frame 2, and the outer wall of T-shaped pipe 23 is connected with The inner wall of the support frame 2 i...

Embodiment 3

[0037] Such as Figure 1-5As shown, on the basis of Embodiment 1, the present invention provides a technical solution: preferably, the lens adjusting device 5 is composed of a connecting ring 15, a primary adjusting plate 16 and a secondary adjusting plate 17, and the top of the connecting ring 15 is connected to the mirror The bottom of the tube 3 is fixedly connected, the outer wall of the primary adjustment plate 16 is provided with an embedding hole 19, and the embedding hole 19 is evenly opened on the top of the primary adjustment plate 16, and the primary adjustment plate 16 and the secondary adjustment plate 17 are set. Multiple adjustments are conducive to improving the observation of the position of the object. The bottom of the connecting ring 15 is fixedly equipped with an elastic expansion member 18. The outer wall of the elastic expansion member 18 is embedded and connected with the inner wall of the insertion hole 19. The primary adjustment plate 16 is elastic whe...

Abstract

The invention discloses a microscope lens magnification switching device, and relates to the technical field of microscopes. The microscope lens magnification switching device comprises a microscope body, a support frame and a lens cone. The top of the microscope body is rotatably connected with the bottom of the support frame, the lens cone is arranged on the right side of the support frame, and an adjusting ring is clamped on the outer wall of the lens cone. The outer wall of the adjusting ring is in sliding connection with the outer wall of the supporting frame, and a lens adjusting device is arranged below the bottom of the lens barrel. According to the invention, through the cooperation of the adjusting ring and the clamping device, the distance between the lens cone and the microscope body can be adjusted so as to adapt to the lengths of different objective lenses, and the hidden danger of collision between the lens of the objective lens and the microscope body when the lens is switched due to the overlong length of the objective lens is avoided; meanwhile, the stability of the lens cone and the support frame can be improved, and when the adjusting ring is in contact with the clamping device, the pop-up piece pops up, so that the distance between the lens cone and the microscope body can be visually seen.

Description

technical field [0001] The invention relates to the technical field of microscopes, in particular to a microscope lens magnification switching device. Background technique [0002] A microscope is an optical instrument composed of a lens or a combination of several lenses. It is a sign that humans have entered the atomic age. It is mainly used to magnify tiny objects and become instruments that can be seen by human eyes. It is divided into optical microscopes and electron microscopes. , a microscope is often configured with multiple objectives with different magnifications. There are following problems at prior art: [0003] 1. At present, when the lens of the microscope is switched, because the lens cannot be adjusted in various ranges, it is inconvenient to adjust the lens with different magnifications to the best observation point of the object when switching, which affects the accuracy of the lens; [0004] 2. The distance between the lens barrel of the microscope and ...
