Description

Technical Field

[0001] The utility model relates to the technical field of cryostat microtomes, and particularly relates to a cryostat microtome facilitating the observation of the sectioning process. Background Art

[0002] A cryostat microtome refers to an instrument that can quickly produce tissue sections for observation by making tissues reach a certain hardness at low temperature. A cryostat microtome consists of a sectioning device and a refrigeration system, and usually consists of a main machine (devices such as a freezing box, a sample head, a quick-freezing table, etc.), a tool rest and a blade to form a complete cryostat sectioning system.

[0003] The freezer door of a cryostat microtome generally adopts a sliding glass door. The sliding glass door is convenient to open and close, and can facilitate the user to observe the sectioning result, thereby ensuring that it is more convenient for the user to adjust the specimen trimming. However, due to the low temperature inside the freezer, the temperature of the glass door is relatively low compared to the temperature outside the box. At this time, when the external hot air contacts the glass door, liquefaction will occur, that is, the water vapor in the hot air turns into liquid water after contacting the glass door;

[0004] The liquid water adhering to the outside of the glass door not only affects the observation, but also easily forms water stains. If a rag is directly used for wiping, it is also easy to leave more stains on the surface of the glass door due to the rag itself not being clean enough, thereby causing a great obstacle to the user's observation. Therefore, a cryostat microtome facilitating the observation of the sectioning process is proposed to solve the above-mentioned problems. Content of the Utility Model

[0005] Based on the above description, the utility model provides a cryostat microtome facilitating the observation of the sectioning process to solve the problem that stains are easily formed on the surface of the glass door of the existing cryostat microtome due to the accumulation of liquid water at a low temperature.

[0032] Please refer to Figure 1 , a cryostat for facilitating the observation of the sectioning process, comprising:

[0033] The cryostat main body 1, which includes a hollow vertical block 12. The cryostat main body 1 includes a housing 11. Both sides of the housing 11 are provided with hollow vertical blocks 12. Vertical side holes 13 are provided on the opposite sides of the hollow vertical blocks 12. The fixing screw 3 extends into the interior of the vertical side hole 13 and is threadedly connected to the movable frame 2.

[0034] The movable frame 2, which is arranged inside the hollow vertical block 12 through the fixing screw 3.

[0035] Based on the above, the hollow vertical block 12 and the vertical side hole 13 cooperate with each other, enabling the movable frame 2 to move vertically along the inner wall of the hollow vertical block 12. And the setting of the vertical side hole 13 enables the fixing screw 3 to move together with the hollow vertical block 12. By tightening the fixing screw 3, the movable frame 2 is closely attached to the inner wall of the hollow vertical block 12, thereby fixing the position of the movable frame 2.

[0036] As Figures 2 - 4 and Figure 8 shown, the connecting member 8, which is arranged between the movable frames 2 and includes an air outlet transverse hole 85.

[0037] The connecting member 8 includes a transverse block 81. Inside the transverse block 81, there are a transverse hole 82, a mounting hole 83, and an air outlet transverse hole 85. The transverse hole 82 and the mounting hole 83 are on the same horizontal line. The air outlet transverse hole 85 is provided on the outer surface of the transverse block 81. The transverse hole 82, the mounting hole 83, and the air outlet transverse hole 85 are interconnected. The inner diameter of the mounting hole 83 is larger than that of the transverse hole 82. On the inner surface of the mounting hole 83, there is a positioning convex block 84;

[0038] Based on the above, on the one hand, the transverse hole 82 provides space for the heating element 4, and on the other hand, it enables air to come into full contact with the heating element 4 for heat exchange. The air outlet transverse hole 85 allows air to be discharged therefrom, and the discharged air can form an air curtain. The mounting hole 83 and the positioning convex block 84 cooperate with each other to position the blowing block 5.

[0039] As Figures 2 - 5 shown, the heating element 4 is arranged at one end of the connecting member 8 and extends into the connecting member 8, and is connected to the movable frame 2 through the internal thread cylinder 7;

[0040] The heating element 4 includes a first externally threaded hollow cylinder 41. On the outer surface of the first externally threaded hollow cylinder 41, there is a first cover plate 42. The first cover plate 42 is arranged at one end of the connecting member 8 through screws. On one side of the first cover plate 42, there is a heating rod 43. The heating rod 43 extends into the transverse hole 82. On the outer surface of the heating rod 43, there is a support block 44. The support block 44 is in contact with the inner wall of the transverse hole 82;

[0041] Based on the above, the first externally threaded hollow cylinder 41 is connected to the movable frame 2 through the internal thread cylinder 7. At this time, by loosening the internal thread cylinder 7 and then rotating the heating element 4, the heating element 4 can rotate with the first externally threaded hollow cylinder 41 as the center. The first cover plate 42 enables the heating element 4 to be connected to the connecting member 8 through screws. The heating rod 43 plays a role in heating air, and the support block 44 plays a supporting role, making the installation of the heating rod 43 more stable.

[0042] As Figures 2 - 7 shown, the blowing block 5 is arranged inside the connecting member 8 through the cover 6. The cover 6 is connected to the movable frame 2 through the internal thread cylinder 7. The blowing block 5 includes a cylinder body 51. On the outer surface of the cylinder body 51, there is a positioning groove 52. Inside the cylinder body 51, there is an electric fan 53;

[0043] The cover 6 includes a second cover plate 61, the second cover plate 61 is arranged at one end of the connecting piece 8 by screws, a second externally threaded hollow cylinder 62 and an air inlet hole 63 are arranged on a side of the second cover plate 61 away from the connecting piece 8, and the second externally threaded hollow cylinder 62 is connected to the movable frame 2 through the internally threaded cylinder 7;

[0044] Based on the above, after the cover 6 and the connecting piece 8 are connected to each other by screws, the blowing block 5 is fixed inside the mounting hole 83. The positioning groove 52 and the positioning convex block 84 cooperate with each other to prevent the blowing block 5 from rotating. After the electric fan 53 is powered on, the air outside the connecting piece 8 is sucked in from the air inlet hole 63, and the air enters the inside of the connecting piece 8 for heating. The second externally threaded hollow cylinder 62 plays the same role as the first externally threaded hollow cylinder 41.

[0045] When this embodiment is actually used, by powering on the heating rod 43 and the electric fan 53, the air outside the connecting piece 8 is sucked into the inside of the cross block 81 and heated under the action of the heating rod 43. The heated air is ejected from the air outlet cross hole 85, and the ejected air flow forms an air curtain above the glass door. On the one hand, the water content of the heated air curtain is reduced, which can prevent the situation of liquefied water accumulating on the surface of the glass door. On the other hand, the air curtain formed by the hot air heats the glass door, thereby avoiding the situation of pre-cooling and liquefaction of the hot air;

[0046] After loosening the fixing screws, the movable frame 2 drives the connecting piece 8 to move vertically, thereby achieving the effect of changing the vertical height of the connecting piece 8. After the movable frame 2 moves vertically, the fixing screws are tightened to achieve the effect of fixing the positions of the movable frame 2 and the connecting piece 8;

[0047] After loosening the internally threaded cylinder 7, the connecting piece 8 rotates around the first externally threaded hollow cylinder 41 and the second externally threaded hollow cylinder 62, thereby changing the angle of the air flow ejected from the air outlet cross hole 85, and further enabling the device to heat a specific position of the glass door;

[0048] The freezing microtome heats the glass door by arranging the connecting piece 8 that can eject hot air, avoiding the situation of liquid water accumulating on the surface of the glass door. And by changing the height and angle of the connecting piece 8, it can heat a specific position of the glass door and can also be adjusted according to actual situations to meet actual needs.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
