Abstract
Description
Technical Field

[0002] A slicing machine is an auxiliary machine that is widely used in medical and biological research to slice tissues embedded in wax. The slices made by a paraffin slicing machine can be used to detect various clinical lesions to ensure that doctors can make more accurate judgments, or to help researchers explore at the tissue and cell levels. After the tissue slices are cut, the operator needs to use hands or tools to take out the tissue slices. For the safety of the operator, the reciprocating robotic arm must be fixed to a certain position through a handwheel so that the operator can take out the cut tissue and prevent the robotic arm from sliding down due to gravity and accidentally injuring the operator. Therefore, a start-stop protection structure needs to be installed on the slicing machine.
[0003] During the use of the start-stop protection mechanism of the slicing machine, the sample is placed on the sample clamping seat, and the telescopic cylinder is controlled to move back and forth by rotating the adjustment knob. Then, the blade is placed between the blade seat and the pressure blade on the tool holder base, and the tool holder base is controlled to move through the tool seat guide rail. The sample clamping seat is driven to move up and down by rotating the large handwheel, and the start and stop of the large handwheel are realized according to the start-stop protection mechanism to avoid the phenomenon of accidentally injuring the operator due to gravity and sliding down.
[0004] During the use of the existing start-stop protection mechanism of the slicing machine, since the existing slicing machine cannot fix and limit the large handwheel, the large handwheel slides down due to gravity and accidentally injures the operator, resulting in the phenomenon of the operator being injured and reducing the safety of the device during use.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0030] Embodiment 1
[0031] Refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 And Figure 7 , which is the first embodiment of the present invention. This embodiment provides a start-stop protection structure for a slicer, including a slicer body 1, a sample clamping seat 101 is arranged on the slicer body 1, a handwheel locking seat 102 is fixedly connected to the outer surface of the slicer body 1, a start-stop component 3 is arranged on the handwheel locking seat 102, a housing 104 is arranged outside the slicer body 1, a large handwheel 105 is movably arranged on the outer surface of the housing 104, a through groove 1051 is opened on the outer side of the large handwheel 105, a gear disk 1052 is fixedly connected inside the large handwheel 105, and a protection component 4 is arranged on the housing 104;
[0032] The start-stop component 3 includes a limit post 301 fixedly connected to the outer surface of the handwheel locking seat 102. A pressing post 302 is inserted through the limit post 301. A cam 303 is inserted through the pressing post 302. One end of the cam 303 away from the pressing post 302 is provided with an abutting rod 304. One end of the abutting rod 304 away from the cam 303 is fixedly connected to a moving rod 305. An abutting block 307 is fixedly connected to the outer surface of the moving rod 305. A spring 306 is arranged between the inner wall of the limit post 301 and the outer surface of the abutting block 307. One end of the moving rod 305 away from the abutting rod 304 is fixedly connected to a moving block 308. A fixed post 309 is fixedly connected to the upper surface of the handwheel locking seat 102. A chute 3091 is formed on the inner wall of the fixed post 309. A sliding rod 310 is fixedly connected to the inner surface of the chute 3091. A plug rod 313 is inserted through the fixed post 309.

[0035] Embodiment 2
[0036] Refer to Figure 1 、 Figure 2 And Figure 3 This is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.
[0037] The protection component 4 includes a screw rod 401 fixedly connected to the outer surface of the housing 104. A limit ring 402 is fixedly connected to the outer surface of the screw rod 401. A bracket 403 threadedly connected to the screw rod 401 is arranged on one side of the limit ring 402. A knob 404 is arranged on the side of the bracket 403 away from the limit ring 402. A connecting rod 405 is fixedly connected to the end of the bracket 403 away from the screw rod 401. A protective cover 406 is fixedly connected to the end of the connecting rod 405 away from the bracket 403
[0038] Specifically, the lower end of the insertion rod 313 is inclined, and the lower end of the insertion rod 313 abuts against the moving block 308. The cross-section of the upper end of the insertion rod 313 is an inverted triangle, and the upper end of the insertion rod 313 penetrates through the through groove 1051 and is clamped with the gear disk 1052. The two ends of the spring 306 are respectively fixedly connected to the inner wall of the limit post 301 and the outer surface of the abutting block 307, and the spring 306 is sleeved on the outer surface of the moving rod 305. The two ends of the telescopic spring 312 are respectively fixedly connected to the inner top wall of the sliding groove 3091 and the upper surface of the sliding plate 311, and the telescopic spring 312 is sleeved on the outer surface of the sliding rod 310. The protective cover 406 is arc-shaped, and the material of the protective cover 406 is transparent acrylic material.
[0039] Furthermore, through the protection component 4, by rotating and loosening the knob 404 threadedly connected to the outer surface of the screw rod 401, when the knob 404 is rotated and loosened, by swinging the bracket 403, when the bracket 403 is subjected to a swinging force, it will swing along the outer surface of the screw rod 401. When the screw rod 401 swings, it will drive the connecting rod 405 at one end of the bracket 403 to swing, thereby driving the protective cover 406 to swing, so as to realize the angle adjustment of the protective cover 406 by swinging the bracket 403 in sequence, thus achieving the protection effect on the slicing machine.
[0040] Working principle: During use, by pressing the pressing column 302, the pressing column 302 drives the cam 303 to move forward. The toothed block on the cam 303 is movably connected to the serrated shape at the lower end of the pressing column 302. When the pressing column 302 moves forward through the notch and the guide rail, it drives the toothed block on the outer surface of the cam 303 to move up and down at the edge of the guide rail. And the toothed block on the outer surface of the cam 303 is located in the middle of the serrated shape at the lower end of the pressing column 302. When the toothed block on the outer surface of the cam 303 moves to the outside of the guide rail and slides to the edge of the guide rail, the cam 303 will rotate. When the pressing column 302 is released, the toothed block contacts the edge of the guide rail, triggering the cam 303 to rotate more. When the toothed block disengages from the edge of the serrated shape at the lower end of the pressing column 302, the toothed block slides into the inside of the guide rail, causing the abutting rod 304 to push the moving rod 305 forward, thereby driving the moving block 308 to move forward, causing the moving block 308 to squeeze the insertion rod 313 upward, so that the upper end of the insertion rod 313 is engaged with the gear disc 1052, thereby limiting and fixing the large handwheel 105, avoiding accidental injury to the operator due to sliding under gravity, and improving the safety of the device. By rotating the knob 404 threadedly connected to the outer surface of the loosening screw 401, when the knob 404 is rotated and loosened, through the swing bracket 403, when the bracket 403 receives a swinging force, it will swing along the outer surface of the screw 401. When the screw 401 swings, it will drive the connecting rod 405 at one end of the bracket 403 to swing. When the connecting rod 405 swings, it will drive the shield 406 to swing, thereby achieving the angle adjustment of the shield 406 by sequentially driving the swing bracket 403, thus achieving the protective effect on the slicer.
