Description

Technical Field

[0001] The utility model relates to the technical field of paraffin slicers, in particular to a stable base of a rotary slicer. Background Art

[0002] Paraffin slicer is an auxiliary machine widely used in medical and biological research. It is used to slice tissues after embedding them in wax. The slices made by paraffin slicer can be used to detect various clinical lesions to ensure that doctors can make more accurate judgments, or help researchers explore at the tissue and cell levels.

[0003] Common paraffin slicers are also called rotary slicers by technicians in this field because they can perform manual slicing through a rotating wheel. Rotary slicers are usually placed on a test bench for use. Common rotary slicers are small in size and light in weight. In actual use, their base lacks a fixed structure, so the slicer may be pushed to move due to accidental collision and other reasons. After the slicer moves, it is easy to collide with other equipment and utensils on the test bench, causing damage to some utensils. If the test bench is small, there is also a risk of the slicer falling from the test bench after movement. When operating through the rotating wheel, if the operator is not proficient enough, the slicer may be pushed to move slightly, affecting the experience during operation. Therefore, a stable base of a rotary slicer is proposed to solve the above-mentioned problems. Utility Model Content

[0004] Based on the above description, the utility model provides a stable base for a rotary slicer to solve the problem that the rotary slicer lacks a fixing mechanism, which causes the slicer to move easily due to accidental collision when placed on a test bench.

[0005] The utility model solves the above-mentioned technical problem with a technical solution as follows: a stable base of a rotary slicer, comprising: a base body and a gasket, the base body and the gasket are sequentially arranged at the bottom end of a slicer body from top to bottom, a mounting hole is arranged on the surface of the base body, a suction cup mechanism comprises a suction cup block, a fixed cover, a hollow movable block, a mounting member, a positioning member and a reset spring, the suction cup block is arranged at the mounting hole, the hollow movable block is arranged inside the suction cup block, the fixed cover is threadedly connected to the suction cup block and is arranged outside the hollow movable block, the mounting member and the positioning member are sequentially arranged between the suction cup block and the fixed cover from top to bottom, and the reset spring is arranged between the mounting member and the hollow movable block.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the suction cup block includes a suction cup body, the suction cup body is arranged at the bottom end of the base body, and a hollow vertical cylinder is arranged at the top end of the suction cup body, and the hollow vertical cylinder passes through the mounting hole.

[0008] Furthermore, the outer surface of the suction cup body is provided with threads, the hollow vertical cylinder is connected to the suction cup body, and the inner diameter of the top of the hollow vertical cylinder is greater than the inner diameter of the bottom thereof.

[0009] Furthermore, a through hole is provided at the top end of the fixing cover, and the fixing cover is adapted to the thread and is in contact with the upper surface of the base body.

[0010] Furthermore, the hollow movable block includes a hollow sealing ball, which is arranged inside the hollow vertical cylinder, and the diameter of the hollow sealing ball is smaller than the inner diameter of the top of the hollow vertical cylinder and larger than the inner diameter of the bottom thereof.

[0011] Furthermore, a hollow vertical rod is arranged at the top of the hollow blocking ball, and the hollow vertical rod passes through the through hole. A partition is arranged outside the hollow vertical rod, and the partition is arranged inside the hollow vertical cylinder.

[0012] Furthermore, the mounting member comprises a hollow cylinder, an upper surface of which is provided with a first mounting groove, and the hollow cylinder is arranged inside the hollow vertical cylinder.

[0016] 1. The utility model provides components such as a suction cup block and a hollow movable block, and connects the suction cup block and the base body to each other. When the slicer is placed on the surface of the test bench, the suction cup block is closely attached to the upper surface of the test bench under the action of gravity. In this process, the air between the suction cup body and the test bench is discharged from the hollow vertical cylinder, thereby forming a negative pressure between the suction cup body and the test bench.

[0017] 2. By setting the reset spring, the effect of unidirectional movement of airflow is achieved, so that after the airflow is discharged from the hollow vertical cylinder, the hollow movable block is reset under the action of the downward elastic force of the reset spring, preventing the airflow from returning to between the suction cup body and the test bench, so that the suction cup body is tightly adsorbed on the surface of the test bench under the action of air pressure. When it is necessary to separate the slicer body from the test bench, the hollow movable block can be pulled upward to allow air to enter between the suction cup body and the test bench, thereby causing the suction cup to lose its adsorption ability.

[0033] See also Figure 1-Figure 3 as well as Figure 6 , a stable base for rotary microtomes, including:

[0034] A base body 2 and a gasket 3 are sequentially arranged at the bottom of the slicer body 1 from top to bottom, and a mounting hole is arranged on the surface of the base body 2;

[0035] A suction cup block 4 is arranged at the mounting hole, the suction cup block 4 comprises a suction cup body 41, the suction cup body 41 is arranged at the bottom end of the base body 2, a hollow vertical cylinder 42 is arranged at the top of the suction cup body 41, the hollow vertical cylinder 42 passes through the mounting hole, a thread 43 is arranged on the outer surface of the suction cup body 41, the hollow vertical cylinder 42 is connected with the suction cup body 41, and the inner diameter of the top of the hollow vertical cylinder 42 is greater than the inner diameter of the bottom thereof;

[0036] Based on the above, the gasket 3 plays a role in supporting the base body 2, so that after the air between the suction cup block 4 and the laboratory table is discharged, the gasket 3 can provide sufficient support for the base body 2, and the mounting hole allows the position of the suction cup block 4 to be fixed.

[0037] like Figure 4 , Figure 5 as well as Figure 7 As shown, the hollow movable block 6 is arranged inside the suction cup block 4, and the hollow movable block 6 includes a hollow blocking ball 61, and the hollow blocking ball 61 is arranged inside the hollow vertical cylinder 42, and the diameter of the hollow blocking ball 61 is smaller than the inner diameter of the top of the hollow vertical cylinder 42 and larger than the inner diameter of the bottom thereof, and a hollow vertical rod 62 is arranged on the top of the hollow blocking ball 61, and the hollow vertical rod 62 passes through the through hole, and a partition 63 is arranged outside the hollow vertical rod 62, and the partition 63 is arranged inside the hollow vertical cylinder 42;

[0038] Based on the above, the hollow movable block 6 plays the role of blocking the hollow vertical cylinder 42. When the suction cup body 41 and the laboratory table surface are squeezed against each other, the airflow hits the hollow movable block 6 upward, so that after the hollow movable block 6 moves upward, the airflow can be discharged from the hollow vertical cylinder 42. The setting of the partition 63 enables the hollow movable block 6 and the reset spring 9 to cooperate with each other.

[0039] like Figure 3-Figure 5 As shown, the fixed cover 5 is threadedly connected to the suction cup block 4 and is arranged outside the hollow movable block 6. The top of the fixed cover 5 is provided with a through hole. The fixed cover 5 is adapted to the thread 43 and is in contact with the upper surface of the base body 2.

[0040] Based on the above, the fixed cover 5 is connected to the hollow vertical cylinder 42, which plays the role of fixing the mounting member 7, the positioning member 8 and the suction cup block 4, so that the mounting member 7 and the positioning member 8 are fixed between the fixed cover 5 and the hollow vertical cylinder 42, and the suction cup block 4 is connected to the base body 2.

[0041] like Figure 3-Figure 5 , Figure 8-Figure 10 As shown, the mounting member 7 and the positioning member 8 are sequentially arranged between the suction cup block 4 and the fixing cover 5 from top to bottom, the mounting member 7 comprises a hollow cylinder 71, the upper surface of the hollow cylinder 71 is provided with a first mounting groove 72, the hollow cylinder 71 is arranged inside the hollow vertical cylinder 42, the outer surface of the hollow cylinder 71 is provided with a positioning ring 73, the upper surface of the positioning ring 73 is provided with a connecting hole 74, the positioning ring 73 is arranged at the top end of the hollow vertical cylinder 42, and the connecting hole 74 is connected with the hollow vertical cylinder 42;

[0042] The positioning member 8 includes an annular plate 81, which is arranged between the fixing cover 5 and the mounting member 7. The bottom end of the annular plate 81 is provided with a second mounting groove 82, a ball is arranged between the second mounting groove 82 and the first mounting groove 72, and a connecting groove 83 is arranged on the upper surface of the annular plate 81.

[0043] a return spring 9, which is arranged between the mounting member 7 and the hollow movable block 6;

[0044] Based on the cooperation between the above-mentioned mounting member 7 and the positioning member 8, on the one hand, the airflow can pass through the connecting groove 83 and the connecting hole 74 and then be discharged from the through hole. On the other hand, the cooperation with the ball makes the vertical movement of the hollow movable block 6 smoother to avoid jamming. The reset spring 9 plays a reset role. When the hollow movable block 6 moves upward, the reset spring 9 is compressed to generate a reverse elastic force, so that the hollow movable block 6 is reset under the action of the elastic force after the airflow is discharged, thereby avoiding the occurrence of airflow backflow.

[0045] In actual use of this embodiment, by placing the slicer body 1 on the experimental table, the suction cup body 41 is closely attached to the table under the action of gravity. In this process, the air between the suction cup body 41 and the table is squeezed and moves upward along the hollow vertical cylinder 42. At this time, the airflow impacts the hollow movable block 6, so that the hollow movable block 6 moves upward. In this process, the ball plays a role of auxiliary movement;

[0046] After the hollow movable block 6 moves upward, the return spring 9 is compressed to generate elastic force. At this time, there is a gap between the hollow blocking ball 61 and the hollow vertical cylinder 42, so that the airflow can flow into the hollow vertical cylinder 42. A part of the airflow directly flows through the mounting member 7, the positioning member 8 and the fixing cover 5 and is discharged. The other part of the airflow flows through the connecting hole 74 and the connecting groove 83 and is discharged from the through hole.

[0047] When the airflow is exhausted, the suction cup body 41 is tightly attached to the experimental table under the action of air pressure, thereby achieving the effect of fixing the slicer body 1. At the same time, the hollow movable block 6 is reset under the action of elastic force, achieving the blocking effect again to prevent the airflow from flowing back.

[0048] When the slicer body 1 needs to be moved, the hollow movable block 6 can be pulled upward to allow air to enter between the suction cup body 41 and the laboratory table surface. At this time, the air pressure between the suction cup body 41 and the table surface is consistent with the atmospheric pressure, so the slicer body 1 can be directly moved;

[0049] The device enables the slicer body 1 to be fixed on the experimental table surface by arranging a suction cup mechanism, thereby preventing the slicer body 1 from moving due to accidental collision or the like.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
