[0002] A microscope is an optical instrument composed of one lens or a combination of several lenses. It is a symbol of mankind entering the atomic age. Microscopes are mainly used to magnify tiny objects so that they can be seen by the naked eye. Microscopes are divided into optical microscopes and electron microscopes: The optical microscope was first invented by Janssen of the Netherlands in 1590. Today's optical microscopes can magnify objects 1600 times, and the minimum resolution limit is 1 / 2 of the wavelength. The length of the mechanical tube of a domestic microscope is generally 160 mm.

[0003] In the use of a microscope, a base fixing mechanism plays a role of fixing and supporting, and provides assistance for the cultivation of biological experiments. However, the existing microscope base fixing mechanism generally does not have the function of maintaining a constant temperature and assisting heating of biological culture dishes. At the same time, part of the base is heated unevenly, which causes certain inconveniences in use. Based on this, a base fixing device for a microscope for biological experiments is proposed.

A support shaft seat 15 is fixedly installed at the bottom of the inner cavity of the base 5, a rotating rod 14 is movably sleeved on the inner side of the support shaft seat 15, a plurality of stirring blades 18 are fixedly installed on the outer side of the top of the rotating rod 14, a gear 20 is fixedly sleeved on the outer side of the rotating rod 14, a rack 19 is meshed on the outer side of the gear 20, a piston push rod 11 is fixedly installed on one end of the rack 19, a sleeve 10 is movably sleeved on the outer side of the piston push rod 11, a piston head 23 is fixedly installed on the other end of the rack 19, a sleeve 21 is movably sleeved on the outer side of the piston head 23, a reset spring 22 is fixedly installed on one side of the piston head 23, a plurality of through holes 24 are opened on the end of the sleeve 21 away from the piston head 23, and a pressure relief valve 12 is connected to the outer side of the base 5.

[0021] The working principle of the above technical solution is as follows: when in use, the user slides the movable frame 8 and the support rod 9, and fixes the position of the movable frame 8 and the support rod 9 by bolts and jackscrews, and then operates by sleeve-fitting the mounting mechanism of the electron microscope on the outer side of the support rod 9, and then fixes it. When it is necessary to place the biological experiment culture vessel on the inner side of the placement groove 6, and then start the vortex electric heater 17, the operator presses the piston push rod 11, the piston push rod 11 moves to push the rack 19 to move, the rack 19 drives the meshing gear 20 to rotate, and the gear 20 rotates the force The force is applied to the rotating rod 14, which rotates with the support of the supporting shaft seat 15 and causes the stirring blade 18 to rotate. The rotation of the stirring blade 18 causes the heat-conducting medium liquid inside the base 5 to flow, and drives the heat of the vortex electric heater 17 to stir, so as to promote uniform heating. The other end of the rack 19 moves and compresses the reset spring 22 at the same time with the support of the piston head 23, so that the rack 19 resets after the piston push rod 11 is released and pressed, which is convenient for subsequent pressing, so that the heat-conducting medium liquid inside the base 5 can be stably heat-conducted, which is convenient for uniform and rapid heating.

[0022] In another embodiment, Figure 1 and Figure 2 As shown, the support rod 9 is fixed inside the middle part of the movable frame 8 by means of a top screw, grooves are provided on the backs of the two pillars 7, and the movable frame 8 is fixed to the outer sides of the pillars 7 by means of bolts passing through.

[0023] The support rod 9 and the movable frame 8 are fixed by bolts and jackscrews, so that the height of the support rod 9 and the height of the movable frame 8 can be adjusted, which is convenient for the installation of the electron microscope and increases the convenience of adjusting the height.

[0025] The support shaft seat 15 provides rotation for the rotating rod 14 and is located at the center of the base 5, the vortex hollow bracket 16 and the vortex electric heater 17, so that when the rotating rod 14 rotates and drives the stirring blade 18 to rotate, the internal heat-conducting medium liquid is evenly stirred, thereby increasing the uniformity of heating.

[0026] In another embodiment, Figure 2 As shown, the two pillars 7 are both fixed inside the support 1 by bolt threads penetrating the support 1 and resting against the outside of the pillars 7 .

[0027] The support 7 is fixed inside the support 1 by bolts, which facilitates the disassembly of the support 7 and the installation and fixation to achieve the effect of the supporting structure, thereby increasing the convenience of use.

[0028] In another embodiment, Figure 3-Figure 5 As shown, the second sleeve 21 is fixedly installed inside the base 5 , and one end of the return spring 22 away from the piston head 23 is fixedly installed inside the second sleeve 21 .

[0029] The sleeve 21 fixes the piston head 23 to provide support, and the return spring 22 provides the piston head 23 with a return elastic force, which is convenient for applying a force to the inner side of the rack 19, facilitating the reciprocating movement of the rack 19, facilitating use, increasing the stability of the structure, and stabilizing the torque.

[0030] In another embodiment, Figure 3-Figure 5 As shown, sleeve 10 is fixedly sleeved through the base 5 and extends to the outside of the base 5, the piston push rod 11 extends to the outside of sleeve 10, the through holes 24 are evenly distributed in a circle inside sleeve 21, and 80%-90% of the heat conductive medium liquid is set inside the base 5.

[0031] The heat-conducting medium liquid is one of water, ethylene glycol or a mixture with glycerol. By using a similar heating technology to the hand warmer, the existing technology is used to limit the heating power of the vortex electric heater 17 to maintain a constant low-temperature heating state. When the piston head 23 moves, the liquid flows out through the through hole 24 to avoid pressure difference during movement. Through the provided stirring blades 18 and the vortex electric heater 17, the base 5 is filled with 80%-90% of the heat-conducting medium liquid, so that the bottom and the outer side of the placement groove 6 are in contact with the heat-conducting medium liquid and a certain fault tolerance space is left. Since the heat-conducting medium liquid has a large specific heat capacity, it can be heated evenly and the temperature can be maintained, which is convenient for the biological culture vessel to not lose temperature when observed through an electron microscope. The vortex-shaped uniform heating of the vortex electric heater 17 and the rotation and stirring of the stirring blades 18 make the temperature inside the base 5 evenly rise, thereby increasing the uniformity of heating.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
