Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a freezing microtome used for botanical experiments. Background Art

[0002] Frozen sectioning is a method of slicing tissues by rapidly freezing them at low temperatures to a certain hardness. It does not require dehydration and transparency steps and is fast, simple, and easy to operate. It can also preserve the enzyme activity of tissues and the immune activity of tissue antigens. It is a commonly used method in experiments such as in situ hybridization, enzyme histochemistry, and immunohistochemistry. There are many types of frozen sections, and commonly used slicers are divided into two categories: open cryostat and constant temperature cryostat.

[0003] According to the patent publication number CN207991909U, a freezing slicer for botanical experiments is disclosed, which includes a No. 1 blade, a picking needle and a No. 2 blade; a total of two No. 1 electric push rods are fixedly and symmetrically arranged on the top of the clamp seat, and a lower clamp is fixedly arranged on the top of each No. 1 electric push rod.

[0004] The above scheme can avoid curling of slices and effectively reduce the difficulty of operation. However, the above scheme has certain shortcomings in actual use. Through the cooperation between blade No. 1 and blade No. 2, the two blades can simultaneously play an anti-curling role during the slicing process. However, after the blade slices the plant tuber, plant body residues and dust will adhere to the blade. Before slicing another plant tuber, the blade needs to be cleaned to ensure the cleanliness of the blade. In the above scheme, the distance between the two blades is relatively close, and the two blades are in a narrow space. Therefore, it is inconvenient to clean the blade, which may cause cleaning dead corners, and there are certain shortcomings. To this end, we provide a freezing slicer for botanical experiments to solve the above problems. Utility Model Content

[0024] The present embodiment provides a freezing microtome for botanical experiments. The utility model can quickly release the fixed limit of the fixed rod 5 by setting a limit mechanism 4, and then can quickly release the fixed limit of the blade 7, so that the blade 7 can be quickly disassembled. At this time, it is more convenient to clean the blade 7, avoiding cleaning dead corners, and the cleaning effect is better.

[0025] See also Figure 1 to Figure 5 A freezing microtome used for botanical experiments comprises a bottom plate 1, and an adjustment mechanism 2 is arranged above the bottom plate 1.

[0026] The adjustment mechanism 2 includes a motor 201 . A fixing plate 202 is fixedly connected to the outer surface of the motor 201 , and a bottom surface of the fixing plate 202 is fixedly connected to the upper surface of the bottom plate 1 .

[0027] The output end of the motor 201 is fixedly connected with a screw rod 203 , the outer surface of the screw rod 203 rotates with the inside of the fixed plate 202 , the outer surface of the screw rod 203 is connected with the internal thread of the moving component 3 , and the outer surface of the screw rod 203 rotates with the inside of the support plate 8 .

[0028] By starting the motor 201 through an external controller, the screw rod 203 can be driven to rotate, thereby driving the movable component 3 to move left and right, and at the same time driving the upper limiting mechanism 4, the fixed rod 5 and the blade 7 to follow the movement, so that the plant tuber can be sliced ​​by the blade 7.

[0029] The upper surface of the base plate 1 is slidably connected with a moving component 3 .

[0030] The moving assembly 3 includes a support frame 301 , a second slot 302 is provided inside the support frame 301 , a limiting slot 303 is provided inside the support frame 301 , and the limiting slot 303 slides with the fixing rod 5 , and a threaded slot 304 is provided inside the support frame 301 .

[0031] The fixing rod 5 slides in the limiting groove 303 , so as to achieve a limiting effect on the fixing rod 5 .

[0032] A limiting mechanism 4 is provided inside the moving assembly 3 .

[0033] The limiting mechanism 4 includes a pull block 401, and an insert rod 402 is fixedly connected to the outer surface of the pull block 401. The insert rod 402 is designed to be square in shape and fits with the slot 2 302 and the slot 1 6, thereby preventing the fixed rod 5 and the blade 7 from rotating and ensuring that the blade 7 is more stable when slicing.

[0034] The outer surface of the plug rod 402 slides with the inside of the slot 2 302 , and the plug rod 402 is plugged into the inside of the slot 1 6 . The outer surface of the plug rod 402 is slidably connected with the fixing plate 403 , and the outer surface of the fixing plate 403 is fixedly connected to the outer surface of the support frame 301 .

[0035] The outer surface of the insertion rod 402 is sleeved with an elastic member 404, which is made of a spring. It deforms when subjected to force and stores potential energy. When the force is reduced, it releases the potential energy and gradually recovers the deformation. One end of the elastic member 404 is fixedly connected to the outer surface of the pull block 401, and the other end of the elastic member 404 is fixedly connected to the outer surface of the fixing plate 403.

[0036] By pulling the pull block 401 to the left, the insertion rod 402 can be driven to move along, and then the elastic member 404 can be squeezed. At this time, the elastic member 404 will be deformed and store a certain potential energy. When the pull block 401 is released, the deformed elastic member 404 will release the potential energy, and then the pull block 401 and the insertion rod 402 will be driven to move to the right, thereby achieving a quick reset effect of the pull block 401 and the insertion rod 402.

[0037] A fixed rod 5 is slidably connected inside the moving component 3 , a slot 6 is provided inside the fixed rod 5 , a blade 7 is fixedly connected to the outer surface of the fixed rod 5 , and a support plate 8 is fixedly connected to the upper surface of the bottom plate 1 .

[0038] A pressing mechanism 9 is provided inside the supporting plate 8 .

[0039] The clamping mechanism 9 includes a pull block 901, the outer surface of which is fixedly connected to a connecting rod 902, and the outer surface of the connecting rod 902 slides with the inside of the support plate 8, and the end of the connecting rod 902 away from the pull block 901 is fixedly connected to the outer surface of the clamp block 11.

[0040] The outer surface of the connecting rod 902 is sleeved with an elastic part 903, which is made of a spring. It deforms when subjected to force and stores potential energy. When the force is reduced, it releases the potential energy and gradually recovers the deformation. One end of the elastic part 903 is fixedly connected to the outer surface of the clamping block 11, and the other end of the elastic part 903 is fixedly connected to the outer surface of the support plate 8.

[0041] Pull the pull block 901 upwards, and the pull block 901 will drive the connecting rod 902 and the clamp block 11 to move along, and squeeze the elastic member 903 at the same time, and then place the plant tuber to be sliced ​​on the clamp block 10, and then release the pull block 901, and the compressed elastic member 903 will push the clamp block 11, the connecting rod 902 and the pull block 901 to move downwards, and the clamp block 11 will press and limit the plant tuber placed on the clamp block 10.

[0042] A clamping block 10 is fixedly connected to the outer surface of the support plate 8 , and a clamping block 2 11 is slidably connected to the outer surface of the support plate 8 .

[0043] A layer of buffer sponge pad is fixedly attached to the sides of the clamping block 10 and the clamping block 2 11 that are close to each other, so as to protect the plant tuber body.

[0044] Working principle: When the utility model is in use, first pull the pull block 2 901 upwards, at this time the pull block 2 901 will drive the connecting rod 902 and the clamp block 2 11 to move with it, and at the same time squeeze the elastic member 2 903, and then place the plant tuber to be sliced ​​on the clamp block 1 10, and then release the pull block 2 901, at this time the compressed elastic member 2 903 will push the clamp block 2 11, the connecting rod 902 and the pull block 2 901 to move downwards, and at this time the clamp block 2 11 will press and limit the plant tuber placed on the clamp block 10, and then start the motor 201 through the external controller, which can drive the screw rod 203 to rotate , and then can drive the moving component 3 to move left and right, and at the same time can drive the upper limiting mechanism 4, the fixed rod 5 and the blade 7 to move with it, so that the plant tuber can be sliced ​​by the blade 7, and by pulling the pull block 401 to the left, it can drive the insertion rod 402 to move with it. At this time, the insertion rod 402 will be pulled out of the slot 6 to release the limit on the fixed rod 5. At this time, the fixed rod 5 can be moved upward to disengage from the limit of the limiting groove 303, and at the same time, it can drive the blade 7 to move with it, so that the blade 7 can be quickly disassembled. At this time, it is more convenient to clean the blade 7, avoiding cleaning dead corners, and the cleaning effect is better.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
