Description

Technical Field

[0001] This invention relates to the field of slicing machine technology, specifically to an anti-collision slicing machine blade holder. Background Technology

[0002] A microtome is a device specifically designed for slicing biological tissue samples in biological, medical, and scientific research fields. This device can cut biological tissue into very small, thin sections for easy observation and analysis. Microtome systems typically employ micro-blowing technology, which allows for precise control of the blade's movement, ensuring that the resulting slides have ideal thickness and quality. These slides are commonly used in microscopic observation, cytological research, and pathological diagnosis.

[0003] Existing microtome technology generally uses a rotating wheel to move the specimen up and down by a clamp. The specimen moves up and down and comes into contact with the blade. The movement causes the blade to cut and slice the specimen, thus achieving the purpose of slicing. However, because existing microtome technology requires the clamp to move slightly to bring the specimen closer to the blade during slicing, the up-and-down clamp may come into direct contact with the blade during repeated cuts or improper operation by the user. This can cause blade collision, which can easily damage or shift the internal parts of the microtome, thus affecting the accuracy of the microtome. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an anti-collision slicer blade holder, which solves the problem that in existing slicers, during repeated cutting or improper user operation, the vertically moving clamp will directly contact the blade during movement, resulting in blade collision. This can easily cause damage and displacement of internal parts of the slicer, thus affecting the slicer's accuracy.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0031] Example 1

[0032] Please see Figures 1-7 This invention provides a technical solution: a collision-resistant slicer holder, comprising a base plate 1 and a slicer housing 2. The slicer housing 2 is mounted on the top surface of the base plate 1. A setting plate 3 is mounted on the top surface of the base plate 1. A rotating wheel 4 is mounted on one side surface of the slicer housing 2. A moving groove 5 is mounted on one side surface of the slicer housing 2. A clamp 6 is mounted on the inner wall of the moving groove 5. A clamping plate 7 is mounted on the bottom surface of the clamp 6. A clamping groove 8 is formed on one side surface of the clamp 6. A protective inclined surface 9 is mounted on the bottom surface of the clamping plate 7. An adjustment component is mounted on the top surface of the base plate 1. A collision-resistant component is mounted on the top surface of the adjustment component.

[0033] The rotating wheel 4 is rotatably connected to one side surface of the slicer housing 2, the outer surface of the clamp 6 is in movable contact with the inner wall of the moving groove 5, the outer surface of the clamping plate 7 is rotatably connected to the inner wall of the clamp 6, and the top surface of the clamping plate 7 is in movable contact with the bottom surface of the clamp 6.

[0034] The adjustment assembly includes an adjustment base 10, a limit plate 11 mounted on the top surface of the adjustment base 10, an adjustment bolt 12 mounted on the inner wall of the adjustment base 10, an adjustment knob 13 mounted on one end of the adjustment bolt 12, a contact groove 14 mounted on the top surface of the adjustment base 10, an adjustment platform 15 mounted on the top surface of the adjustment base 10, a limit groove 16 formed on the bottom surface of the adjustment platform 15, and adjustment teeth 17 formed on the bottom surface of the adjustment platform 15. The adjustment base 10 is mounted on the top surface of the setting plate 3.

[0035] The adjusting bolt 12 is rotatably connected to the inner wall of the adjusting base 10. The outer surface of the limiting plate 11 is in contact with the inner wall of the limiting groove 16. The bottom surface of the adjusting platform 15 is in contact with the top surface of the adjusting base 10. There are several adjusting teeth 17, which are distributed linearly and equidistantly on the bottom surface of the adjusting platform 15. The outer surface of the adjusting teeth 17 is in contact with the outer surface of the adjusting bolt 12. The adjusting bolt 12 and the adjusting teeth 17 mesh with each other.

[0036] The rotating adjustment knob 13 will drive the adjustment bolt 12 to rotate. Because the outer surface of the adjustment bolt 12 has a spiral groove, and the adjustment tooth 17 meshes with the adjustment bolt 12, the rotating adjustment bolt 12 will push the adjustment tooth 17 to move through the thread on its surface. The adjustment tooth 17 is fixedly connected to the adjustment platform 15. So when the adjustment bolt 12 rotates, it will push the adjustment platform 15 to rotate through the adjustment tooth 17. The bottom surface of the adjustment platform 15 has a limit groove 16. At this time, the inner wall of the limit groove 16 is in contact with the outer surface of the limit plate 11. When the user rotates the adjustment knob 13, the adjustment platform 15 will rotate slightly on the top surface of the adjustment base 10, thereby realizing the adjustment of the angle of the tool holder 23.

[0037] Example 2

[0038] Based on the above embodiment 1, please refer to Figures 8-10The anti-collision assembly includes a bearing 18, an adjustment groove 19 on the top surface of the adjustment platform 15, a screw 20 installed on the inner wall of the bearing 18, a ball nut 21 installed on the outer surface of the screw 20, an installation block 22 installed on the outer surface of the ball nut 21, a knife holder 23 installed on the top surface of the installation block 22, an installation groove 24 on the top surface of the knife holder 23, a moving plate 25 installed on the top surface of the installation groove 24, a blade groove 26 on one side surface of the moving plate 25, a slicing blade 27 installed on the inner wall of the blade groove 26, a positioning groove 28 on the top surface of the installation groove 24, a first magnet 29 installed on the top surface of the installation groove 24, a second magnet 30 installed on the bottom surface of the moving plate 25, a reset block 31 installed on the top surface of the moving plate 25, an anti-collision ramp 32 installed on one side surface of the knife holder 23, a protective plate 33 installed on the top surface of the knife holder 23, and the bearing 18 installed on one side surface of the adjustment platform 15.

[0039] The outer surface of the bearing 18 is fixedly connected to one side surface of the adjustment platform 15, the outer surface of the bearing 18 is rotatably connected to the outer surface of the screw 20, one end of the screw 20 extends from the inner wall of the bearing 18 to the inner wall of the adjustment groove 19, the inner wall of the ball nut 21 is rotatably connected to the outer surface of the screw 20, and the outer surface of the ball nut 21 is fixedly connected to the inner wall of the mounting block 22.

[0040] The top surface of the mounting block 22 is fixedly connected to the bottom surface of the tool holder 23. The bottom surface of the tool holder 23 is in contact with the top surface of the adjusting platform 15. The bottom surface of the moving plate 25 is in contact with the top surface of the mounting groove 24. The bottom surface of the moving plate 25 is in contact with the inner wall of the positioning groove 28. There are four first magnets 29, which are arranged in a linear array and equidistantly distributed on the top surface of the mounting groove 24. There are two second magnets 30, which are equidistantly distributed on the bottom surface of the moving plate 25. The first magnets 29 and the second magnets 30 are in contact with each other. One side surface of the anti-collision slope 32 is in contact with one side surface of the protective slope 9.

[0041] When the moving plate 25 moves, the change in position causes the top surface of the slicing blade 27 to no longer contact the bottom surface of the clamping plate 7. At this time, the clamping fixture 6 will drive the clamping plate 7 to continue to move downward. As the clamping plate 7 continues to move downward, the protective inclined surface 9 on one side of the clamping plate 7 will contact the anti-collision inclined surface 32 on one side of the blade holder 23. Through the mutual compression of the two inclined surfaces, the blade holder 23 will move. The moving blade holder 23 will drive the mounting block 22 installed on its bottom surface to move. The inner wall of the mounting block 22 is fixedly connected to the outer side of the ball nut 21. The moving blade holder 23 will drive the ball nut 21 to move along the surface of the screw 20 through the mounting block 22, thereby realizing the overall movement of the blade holder 23. The movement of the blade holder 23 will prevent the slicing blade 27 from contacting the clamping plate 7, thus achieving the anti-collision function.

[0042] When using a collision-resistant blade slicer, the specimen to be sliced ​​is placed on the inner wall of the clamp 6, and the clamping plate 7 is rotated so that the top surface of the clamping plate 7 contacts the bottom surface of the specimen, thereby fixing the specimen in the clamp 6. When the angle needs to be adjusted after fixing, the adjustment knob 13 is held and rotated. One side of the adjustment knob 13 is fixedly connected to one end of the adjustment bolt 12. Rotating the adjustment knob 13 will drive the adjustment bolt 12 to rotate. Because the outer surface of the adjustment bolt 12 has a spiral groove, and the adjustment tooth 1... The adjusting bolt 12 and the adjusting bolt 7 mesh with each other, so the rotating adjusting bolt 12 will push the adjusting tooth 17 to move through the thread on its surface. The adjusting tooth 17 is fixedly connected to the adjusting platform 15, so when the adjusting bolt 12 rotates, it will push the adjusting platform 15 to rotate through the adjusting tooth 17. The bottom surface of the adjusting platform 15 has a limit groove 16. At this time, the inner wall of the limit groove 16 is in contact with the outer surface of the limit plate 11. When the user rotates the adjusting knob 13, the adjusting platform 15 will rotate slightly on the top surface of the adjusting base 10, thereby realizing the adjustment of the angle of the tool holder 23.

[0043] When the user needs to start slicing, the microtome 27 is inserted into the inner wall of the blade groove 26 to install the microtome 27. The user then rotates the rotating wheel 4, causing the clamp 6 to move up and down within the moving groove 5. As the clamp 6 moves, it moves the specimen fixed to its inner wall up and down. When the specimen moves up and down, it comes into contact with the microtome 27, and the microtome 27 cuts the moving specimen, thus slicing it. During use, if the clamp 6 collides with the blade holder 23, the clamping plate 7 mounted on the bottom surface of the clamp 6 will be the first to move during the process. The slicing blades 27 are in contact with each other, and as the clamping plate 6 continues to move, the clamping plate 7 will press the slicing blades 27. The slicing blades 27 are installed in the blade groove 26 opened on one side surface of the moving plate 25. At this time, the slicing blades 27 under the pressure will press the moving plate 25. When the moving plate 25 is pressed, it will move along the positioning groove 28 opened on the top surface of the blade holder 23. At this time, the displaced moving plate 25 will drive the slicing blades 27 to move. When the moving plate 25 moves, the position will change so that the top surface of the slicing blades 27 is no longer in contact with the bottom surface of the clamping plate 7. When the clamp 6 touches the ground, the clamping plate 7 will continue to move downwards. As the clamping plate 7 moves downwards, the protective inclined surface 9 on one side of the clamping plate 7 will come into contact with the anti-collision inclined surface 32 on one side of the tool holder 23. Through the mutual compression of the two inclined surfaces, the tool holder 23 will move. The moving tool holder 23 will then move the mounting block 22 mounted on its bottom surface. The inner wall of the mounting block 22 is fixedly connected to the outer side of the ball nut 21. The moving tool holder 23 will then move the ball nut 21 along the surface of the screw 20 through the mounting block 22, thereby realizing the movement of the tool holder 23. The overall movement of the blade holder 23 prevents the slicing blade 27 from contacting the clamping plate 7, thus achieving the anti-collision function. After the impact is completed, the reset block 31 is pushed. The reset block 31 is fixedly connected to the moving plate 25. When the reset block 31 moves, it will drive the moving plate 25 to move. The bottom surface of the moving plate 25 is equipped with a second magnet 30. When the moving plate 25 moves, the first magnet 29 will contact the second magnet 30. When the two magnets contact each other, they will generate magnetic attraction, causing them to attract each other, thereby resetting the moving plate 25 to the initial position.
