Description

Technical Field

[0001] This utility model relates to the technical field of paraffin slicers, specifically to a paraffin slicer anti-cutting device. Background Technology

[0002] Paraffin microtome is an auxiliary machine widely used in medical and biological research to embed tissues in wax and then slice them. Slices made by paraffin microtome can be used to detect various clinical lesions, thus ensuring that doctors can make more accurate judgments, or to help researchers explore at the tissue and cellular level.

[0003] Current anti-cut devices for paraffin slicers typically use protective covers, but this requires operators to manually move the cover onto the blade. If operators forget to move the cover, they are prone to being cut by the blade. Therefore, this invention designs an anti-cut device for paraffin slicers to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a hand-cutting device for a paraffin slicer, in order to solve the problem mentioned in the background art that the current hand-cutting devices for paraffin slicers usually achieve hand-cutting through a protective cover plate. However, this method requires the operator to manually move the protective cover plate onto the blade. When the operator forgets to move the protective cover plate, it is easy to be cut by the blade.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paraffin slicer anti-cutting device, comprising a paraffin slicer body, a paraffin sample body disposed on the paraffin slicer body, a pusher body disposed on the paraffin slicer body, a top plate disposed on the top of the pusher body, side protective covers fixed on both sides of the pusher body, a blade body movably disposed on one end of the pusher body near the paraffin sample body, a recovery groove disposed below the blade body, an adjustment groove disposed below the recovery groove, a fixed partition fixed in the middle of the adjustment groove, a servo motor fixed at the bottom of the adjustment groove, a pulley fixed at the output end of the servo motor, another pulley rotatably connected to the bottom of the fixed partition, the two pulleys being connected by a transmission belt, an inner sleeve rod fixed at the top of the pulley, an outer sleeve rod disposed above the inner sleeve rod, the inner sleeve rod and the outer sleeve rod being threadedly connected, a push plate fixed on the top surface of the outer sleeve rod, and the blade body being fixed by an automatic clamping device.

[0006] Preferably, the automatic clamping device includes a hydraulic rod, the hydraulic rod is fixed inside the push block body, a first limiting block is fixed at the output end of the hydraulic rod, a second limiting block is fixed at the bottom end of the top plate of the push block body, and the hydraulic rod is electrically connected to the push block body.

[0007] Preferably, the height of the blade body is greater than the height of the recycling tank, and the height of the outer sleeve rod is greater than the height of the recycling tank.

[0008] Preferably, the height of the inner sleeve rod is the same as the height of the outer sleeve rod, and both inner sleeve rods are rotatably connected inside the fixed partition.

[0009] Preferably, the opposite sides of the first limiting block and the second limiting block are each provided with a 45° inclined surface, and the inclined surfaces of the first limiting block and the second limiting block are in contact with each other.

[0010] Preferably, the side protective cover limits the top plate of the push block body, and the top plate of the push block body is slidably connected to the inside of the side protective cover.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) This utility model provides a recycling groove below the blade body and a push plate that slides inside the recycling groove. The push plate is controlled by a servo motor to move up and down, so that the push plate moves the blade body up and down. When the operator stops the experiment and pushes the push plate backward, the servo motor automatically starts and drives the push plate to move downward, so that the blade body falls under the action of gravity, avoiding the blade from cutting the operator. When the operator resumes the experiment, the servo motor is started to push the blade body upward. This solves the problem mentioned in the background art that the current anti-cutting device of the paraffin slicer usually achieves anti-cutting through a protective cover plate. However, this method requires the operator to manually move the protective cover plate onto the blade. When the operator forgets to move the protective cover plate, it is easy to be cut by the blade.

[0013] (2) The first limiting block is moved by the hydraulic rod, which causes the first limiting block to move the second limiting block. At the same time, the second limiting block causes the top plate of the push block body to move. Meanwhile, the side protective covers on both sides prevent the top plate of the push block body from falling out of the push block body. The top plate of the push block body clamps and fixes the blade. At the same time, when the worker moves the push block body backward, the hydraulic rod resets, which releases the first limiting block from the second limiting block, thereby resetting the top plate of the push block body and causing the blade body to fall.

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

[0022] Please see Figure 1-4 This utility model provides a technical solution: a paraffin slicer anti-cutting device, including a paraffin slicer body 1, a paraffin sample body 2 disposed on the paraffin slicer body 1, a pusher body 3 disposed on the paraffin slicer body 1, a top plate disposed on the top of the pusher body 3, side protective covers 4 fixed on both sides of the pusher body 3, a blade body 5 movably disposed on one end of the pusher body 3 near the paraffin sample body 2, a collection groove 6 opened below the blade body 5, an adjustment groove 7 opened below the collection groove 6, and a fixed part in the middle of the adjustment groove 7. There is a fixed partition 11, a servo motor 8 is fixed at the bottom of the adjusting groove 7, a pulley 9 is fixed at the output end of the servo motor 8, another pulley 9 is rotatably connected to the bottom of the fixed partition 11, the two pulleys 9 are connected by a transmission belt 10, an inner sleeve rod 12 is fixed at the top of the pulley 9, an outer sleeve rod 13 is sleeved above the inner sleeve rod 12, the inner sleeve rod 12 and the outer sleeve rod 13 are threaded together, a push plate 14 is fixed on the top surface of the outer sleeve rod 13, and the blade body 5 is fixed by an automatic clamping device, so that the push plate 14 controls the lifting and lowering of the blade body 5.

[0023] The blade body 5 is taller than the recycling tank 6, the outer sleeve rod 13 is taller than the recycling tank 6, the inner sleeve rod 12 is the same height as the outer sleeve rod 13, and both inner sleeve rods 12 are rotatably connected to the inside of the fixed partition 11 to prevent the blade body 5 from falling into the recycling tank 6.

[0024] Please see Figure 1-4 The automatic clamping device includes a hydraulic rod 15. The hydraulic rod 15 is fixed inside the push block body 3. A first limiting block 16 is fixed at the output end of the hydraulic rod 15. A second limiting block 17 is fixed at the bottom end of the top plate of the push block body 3. The hydraulic rod 15 is electrically connected to the push block body 3, so that the hydraulic rod 15 automatically resets, and the top plate of the push block body 3 releases control over the blade body 5.

[0025] The first limiting block 16 and the second limiting block 17 each have a 45° inclined surface on their opposite sides. The inclined surfaces of the first limiting block 16 and the second limiting block 17 fit together. The side protective cover 4 limits the top plate of the push block body 3. The top plate of the push block body 3 is slidably connected to the inside of the side protective cover 4 to prevent the top plate of the push block body 3 from coming off.

[0026] The overall working principle is as follows: When the operator stops slicing or changes the paraffin sample body 2, the push block body 3 is pushed backward, and the hydraulic rod 15 automatically resets, causing the top plate of the push block body 3 to spring back, thereby releasing the fixation of the push block body 3 on the blade body 5. At this time, the blade body 5 falls into the recovery tank 6 under the action of gravity. When the operator slices again, the servo motor 8 is started, causing the servo motor 8 to drive the pulley 9 to rotate, which in turn causes the pulley 9 to drive the inner sleeve rod 12 to rotate, which in turn causes the inner sleeve rod 12 to drive the outer sleeve rod 13 to move, which in turn causes the outer sleeve rod 13 to drive the push plate 14 to move, which pushes the blade body 5 outward. At the same time, the hydraulic rod 15 is started, causing the hydraulic rod 15 to drive the first limit block 16 to move upward, which in turn causes the first limit block 16 to drive the second limit block 17 to move, which in turn causes the second limit block 17 to drive the top plate of the push block body 3 to fix and clamp the blade body 5.
