Description

Technical Field

[0001] The utility model relates to the technical field of microscope loading platforms, in particular to an inverted microscope dissection platform. Background Art

[0002] The microscope is a precision instrument commonly used in biological science research and medical experiments. It mainly includes imaging systems, loading systems, lighting systems, focusing mechanisms and other structures. In biomedical research, it is often necessary to finely separate and manipulate tiny tissues or cells. The microscope can magnify the cell tissue placed on the stage, allowing researchers to observe the fine structure of the cell tissue and facilitate experimental operations.

[0003] According to the relative position of the objective lens and the stage, microscopes can be divided into inverted microscopes and upright microscopes. The objective lens of an inverted microscope is located below the stage, while the opposite is true for an upright microscope. The working distance of an inverted microscope is larger than that of an upright microscope, and there is a larger operating space. In addition, there is also a dissecting microscope (also known as a stereo microscope), which has a larger working distance but a low magnification, while an inverted microscope has a higher magnification in comparison, and is therefore particularly suitable for the fine dissection and separation of delicate tissues. During the dissection operation, the sample can be accurately placed in the center of the field of view of the microscope by adjusting the moving direction and distance of the stage. The prior art "A movable optical microscope working platform" (publication number: CN215181180U) discloses a microscope working platform capable of adjusting the relative position, but the prior art still has the following technical problems:

[0004] 1. During the dissection experiment, it is necessary to move the stage to adjust the position of the cell tissue so that the tissue is located in the center of the eyepiece lens, which is convenient for researchers to complete dissection, separation and other experimental operations on the cell tissue at the best viewing angle. The stage base in the prior art is fixed by inserting a positioning pin into the top plate of the platform. When the position of the cell tissue on the stage film is to be adjusted, the stage film needs to be manually slid along the engaging groove for adjustment. Manual adjustment is difficult to operate, so that a slight movement of the stage will cause the cell tissue to move out of the observation range of the eyepiece, increasing the difficulty of experimental operation.

[0005] 2. In order to enable the positioning pins of the loading base to be smoothly inserted into the assembly holes on the platform, the relative positions of the assembly holes need to be very precise, otherwise the loading base cannot be stably fixed on the platform top plate. Not only does the platform top plate need to have a large number of assembly holes, but the position accuracy of each assembly hole is difficult to guarantee, and its manufacturing is difficult and costly. Utility Model Content

[0006] The utility model provides an inverted microscope dissection table, which can solve the problems in the prior art that the microscope stage is difficult to adjust and has low maneuverability, thereby increasing the difficulty of experimental operation.

[0007] The present application provides the following technical solution: an inverted microscope dissection table, comprising a main slide, wherein the main slide comprises an upper slide, a middle slide and a lower slide which are horizontally slidably connected to each other, the middle slide is located between the upper slide and the lower slide, and the sliding direction of the upper slide relative to the middle slide and the sliding direction of the middle slide relative to the lower slide are at right angles to each other;

The piston rod then pushes the piston head to move, and relies on the hydraulic oil in the hydraulic pipe to transmit the driving force to the main slide, thereby achieving precise movement of the main slide. At the same time, when the control lever is reset, the pressing arm is separated from the moment switch, the solenoid valve is closed, and the main slide cannot be subjected to the thrust from the hydraulic cylinder and will stop immediately, allowing researchers to accurately control and stably adjust the position of the main slide and the cell tissue on the main slide, reducing the difficulty of researcher control.

[0013] Beneficial effect: The thrust of the hydraulic cylinder piston rod is transmitted to the first slide column in the first oil channel through the hydraulic oil in the hydraulic pipe, so that the first slide column and the middle slide plate can move synchronously with the hydraulic cylinder piston rod, thereby realizing precise control of the middle slide plate.

[0014] Furthermore, a second oil channel is provided on the middle slide plate, and the opening direction of the second oil channel is at right angles to the first oil channel. The end of the hydraulic pipe away from the transmission chamber is connected to the second oil channel. A second sliding column is slidably connected in the second oil channel.

The second connecting strip extends downward from the second strip opening into the second oil channel and has an interference fit with the second sliding column in the second oil channel.

[0015] Beneficial effect: driven by the piston rod of the hydraulic cylinder, the second slide column and the upper slide plate can also move synchronously with the piston rod of the hydraulic cylinder, thereby realizing precise control of the upper slide plate.

[0017] Beneficial effect: The control lever can swing in both the horizontal and vertical directions, so that the pressing arm on the control lever can touch the inching switch in the corresponding direction, thereby realizing real-time control of the movement state of the hydraulic cylinder piston rod.

[0018] Furthermore, a cross hole is provided on the top of the shell, and the control rod extends out of the cross hole.

[0019] Beneficial effect: the cross hole is convenient for preventing the shaft of the control rod from interfering with the housing when the control rod is swinging.

The head of the pressing arm 803 is located above the inching switch 804. When the control rod 801 swings, the pressing arm 803 can press the corresponding inching switch 804, thereby opening the solenoid valve 10 on the corresponding oil inlet pipeline 9, and then driving the piston rod 6 of the hydraulic cylinder 7 to move in the direction of the swing of the control rod 801; at the same time, the solenoid valve 10 of the other branch on each oil inlet pipeline 9 can be connected in series with another button-type inching switch, and this button switch The switch can be fixed on the side wall of the joystick 801, so that when the user controls the joystick 801, the user can press the button switch on the side wall of the joystick 801 to simultaneously open the two solenoid valves 10 of the two branches on the oil inlet pipeline 9, thereby increasing the oil inlet amount of this oil inlet pipeline 9, thereby accelerating the movement speed of the piston rod 6 of the hydraulic cylinder 7, and facilitating the user to speed up the movement speed of the middle slide 26 and the upper slide 27 when it is necessary to control the middle slide 26 or the upper slide 27 to move a long distance, so as to quickly position them, thereby reducing the control time and improving the overall experimental operation efficiency.
