[0019] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0020] Example like Figures 1 to 14As shown, a high-quality stainless steel pipe cutting device for drinking water includes: a base 1, with two support bars 2 fixedly connected to the bottom of the base 1. The two support bars 2 are symmetrically arranged about the central axis of the base 1. A connecting rod 6 is movably connected to the top of the base 1 near the left side. The connecting rod 6 is vertically arranged and fits against the left side wall of the base 1. A fixing plate 4 is fixedly connected to the right side of the connecting rod 6. Support plates 3 are provided on both the front and rear sides of the fixing plate 4. A pin 5 is rotatably connected to the fixing plate 4. The two ends of the pin 5 are fixedly inserted through the adjacent support plates 3. The support plates 3 are fixedly connected to the top of the base 1. A motor 7 is installed near the top of the right side of the connecting rod 6. A protective cover 8 is provided behind the motor 7. A cutting blade 10 is provided inside the protective cover 8. The power output end of the motor 7 is fixedly connected to the cutting blade 10. A connecting block 9 is fixedly connected to the front side of the protective cover 8. The connecting block 9 is fixedly connected to the rear side wall of the connecting rod 6. A cutting groove 16 is opened near the rear side of the top of the base 1. The cutting groove 16 matches the cutting blade 10.

[0021] In this embodiment, a first screw hole 11 is provided at the top of the connecting rod 6, and an operating rod 12 is inserted into the inner cavity of the first screw hole 11. An external thread 14 is provided on the outer side wall of the operating rod 12, and the external thread 14 matches the first screw hole 11. The external thread 14 is close to the bottom end of the operating rod 12. An anti-slip sleeve 13 is fixedly fitted on the outer top of the operating rod 12. A fixing bracket 17 is fixedly connected to the top of the base 1 near the right side. A support plate 18 and a pressure plate 20 are provided on the inner side of the fixing bracket 17. The top of the support plate 18 and the bottom of the pressure plate 20 are both provided with... The arc-shaped groove 19 and the support plate 18 are located below the pressure plate 20. The support plate 18 is fixedly connected to the top of the base 1. The right side of the pressure plate 20 is fixedly connected to the limiting rod 25. The right side of the fixing frame 17 is provided with a limiting groove 26. The limiting rod 25 moves through the limiting groove 26. The top of the pressure plate 20 is fixedly connected to the first bearing 21. The inner cavity of the first bearing 21 is fixedly inserted with a threaded rod 22. The top of the fixing frame 17 is provided with a second screw hole 23. The top end of the threaded rod 22 passes through the second screw hole 23. The threaded rod 22 is threadedly connected to the second screw hole 23.

[0022] Place the stainless steel drinking water pipe to be cut on top of the support plate 18, and then turn the threaded rod 22 with an external tool. The threaded rod 22 rotates in the inner cavity of the second threaded hole 23 and the first bearing 21. Under the action of the thread, the threaded rod 22 moves downward relative to the second threaded hole 23. The threaded rod 22 drives the first bearing 21 and the pressure plate 20 to move downward. The pressure plate 20 drives the limiting rod 25 to move downward in the inner cavity of the limiting groove 26. The pressure plate 20 moves downward to press and fix the stainless steel drinking water pipe. Then start the motor 7. The motor 7 drives the cutting blade 10 to rotate. Then hold the anti-slip sleeve 13 and flip the operating rod 12 and the connecting rod 6. The connecting rod 6 flips around the pin 5. The connecting rod 6 drives the cutting blade 10 to flip. The cutting blade 10 flips until it touches the stainless steel drinking water pipe, thereby cutting the stainless steel drinking water pipe. After the cutting is completed, lift the connecting rod 6 upward so that the connecting rod 6 is in a vertical state.

[0023] Compared with existing technologies, this device adjusts the height of the pressure plate 20 by rotating the threaded rod 22. The height of the pressure plate 20 is lowered to press and fix the stainless steel drinking water pipe, so that the stainless steel drinking water pipe can be cut. Compared with manual fixation, the fixing method of this device is more stable and avoids unnecessary safety hazards.

[0024] In this embodiment, the bottom of the operating lever 12 is provided with three insertion holes 15, and the top of the threaded rod 22 is provided with a slot 24. The cross-section of the slot 24 is herringbone shaped, and the slot 24 matches the insertion holes 15.

[0025] To avoid spending time searching for tools to tighten the threaded rod 22, the device only requires holding the anti-slip sleeve 13 and unscrewing the operating rod 12 from the first threaded hole 11. At this time, move the operating rod 12 so that the three insertion holes 15 at the bottom of the operating rod 12 are aligned with the herringbone-shaped slot 24 at the top of the threaded rod 22, so that the top of the threaded rod 22 is inserted into the inner cavity of the insertion hole 15. Then, hold the anti-slip sleeve 13 and rotate the operating rod 12, which will drive the threaded rod 22 to rotate. That is, the operating rod 12 of this device can not only be used to flip the extension handle of the cutting disc 10, but also as a tool to tighten the threaded rod 22. It has multiple functions, avoids workers spending time tightening the threaded rod 22, and improves work efficiency.

[0026] The herringbone-shaped slot 24 at the top of the threaded rod 22 can prevent unattended personnel from accidentally twisting the threaded rod 22 during the cutting process, which could cause the stainless steel pipe to loosen, thus avoiding unnecessary safety hazards and ensuring the normal progress of the cutting work.

[0027] In this embodiment, a column 27 is provided on the left side of the fixing frame 17. The column 27 is fixedly connected to the top of the base 1. From bottom to top, a second bearing 28, a spring 29, and a connecting ring 30 are sequentially fitted on the outer side of the column 27. The bottom of the inner ring of the second bearing 28 is fixedly connected to the top of the base 1. The spring 29 and the connecting ring 30 are movably connected to the outer wall of the column 27. The bottom end of the spring 29 is fixedly connected to the top of the outer ring of the second bearing 28, and the top end of the spring 29 is fixedly connected to the connecting ring 30. A limit plate 31 is fixedly connected to the top end of the column 27. A first connecting plate 32 is fixedly connected to the left side of the ring 30. A rod 33 is fixedly connected to the left side of the first connecting plate 32. A limiting hole 34 is provided on the fixing plate 4. A second connecting plate 35 is fixedly connected to the top of the connecting ring 30 near the front side. A cylinder 36 is fixedly connected to the front side of the second connecting plate 35. The rod 33 matches the limiting hole 34 and the rod 33 moves through the limiting hole 34. The bottom of the first connecting plate 32 and the top of the fixing plate 4 fit together. The cylinder 36 matches the threaded rod 22. A rubber pad 37 is fixedly connected to the top of the inner cavity of the cylinder 36.

[0028] To prevent the cutting disc 10 from tipping over when not in use, when the cutting disc 10 is finished or not in use, the connecting rod 6 is lifted upwards so that the connecting rod 6 is in a vertical position and fits against the left side wall of the base 1. The connecting ring 30 is then moved upwards, moving along the outer edge of the column 27. Simultaneously, the spring 29 is stretched, and the connecting ring 30 drives the first connecting plate 32 and the second connecting plate 35 to move upwards. The first connecting plate 32 drives the insert rod 33 to move, and the second connecting plate 35 drives the cylinder 36 to move, maintaining the upward force on the connecting ring 30. Then, the connecting ring 30 is rotated. The connecting ring 30 drives the spring 29 to rotate on the outer ring of the second bearing 28. The connecting ring 30 drives the insertion rod 33 to rotate together. When the insertion rod 33 rotates above the limiting hole 34, the connecting ring 30 stops rotating and then the upward force on the connecting ring 30 is slowly released. Under the elastic action of the spring 29 and the action of gravity, the connecting ring 30 and the insertion rod 33 move downward. The insertion rod 33 is inserted into the inner cavity of the limiting hole 34. At this time, the insertion rod 33 and the limiting hole 34 cooperate with each other to fix the fixing plate 4, preventing the fixing plate 4 and the connecting rod 6 as a whole from flipping down, thereby preventing the cutting disc 10 from flipping down when not in use.

[0029] When the cutting disc 10 is needed, the stainless steel pipe to be cut has been fixed by tightening the threaded rod 22 using the operating lever 12 as a tool. Then, hold the anti-slip sleeve 13 with one hand and move the connecting ring 30 upward with the other hand. The connecting ring 30 moves on the outer edge of the column 27, while the spring 29 is stretched. The connecting ring 30 drives the first connecting plate 32 and the second connecting plate 35 to move upward. The first connecting plate 32 drives the insertion rod 33 to move, and the second connecting plate 35 drives the cylinder 36 to move, maintaining the upward force of the connecting ring 30. Then, rotate the connecting ring 30. The connecting ring 30 drives the spring 29 to rotate on the outer ring of the second bearing 28. The connecting ring 30 drives the insertion rod 33 to rotate together. The connecting ring 30 drives the insertion rod 33 away from the limiting hole 34 through the first connecting plate 32, thereby releasing the connection. With the rod 6, fixing plate 4, and cutting blade 10 fixed, the cutting blade 10 can be flipped for cutting. Then, the connecting ring 30 continues to rotate. The connecting ring 30 drives the cylinder 36 to rotate above the threaded rod 22 via the second connecting plate 35. Then, the upward force on the connecting ring 30 is slowly released. The connecting ring 30 and the cylinder 36 move downward under the elastic action of the spring 29 and gravity. The cylinder 36 is fitted onto the outer top of the threaded rod 22. At this time, the cylinder 36 covers the slot 24. The rubber pad 37 on the top of the cylinder 36 fits against the top of the threaded rod 22. The rubber pad 37 increases the friction at the top of the inner cavity of the cylinder 36, which can prevent the threaded rod 22 from deflecting due to mechanical vibration during the cutting process, thereby preventing the clamped stainless steel tube from loosening and ensuring safety during the cutting process.

[0030] The connecting ring 30, insert rod 33, cylinder 36, column 27 and spring 29 work together to fix the cutting disc 10 when not in use, and also to fix the threaded rod 22 during the cutting process. Fixing the cutting disc 10 when not in use prevents it from flipping down. Fixing the threaded rod 22 prevents it from deflecting due to mechanical vibration during the cutting process, thus preventing the clamped stainless steel tube from loosening and ensuring safety during the cutting process.

[0031] Implementation plan: During use, place the stainless steel drinking water pipe to be cut on top of the support plate 18, and then use an external tool to turn the threaded rod 22. The threaded rod 22 rotates in the inner cavity of the second threaded hole 23 and the first bearing 21. Under the action of the thread, the threaded rod 22 moves downward relative to the second threaded hole 23. The threaded rod 22 drives the first bearing 21 and the pressure plate 20 to move downward. The pressure plate 20 drives the limiting rod 25 to move downward in the inner cavity of the limiting groove 26. The pressure plate 20 moves downward to press and fix the stainless steel drinking water pipe. Then start the motor 7. The motor 7 drives the cutting blade 10 to rotate. Then hold the anti-slip sleeve 13 and flip the operating rod 12 and the connecting rod 6. The connecting rod 6 flips around the pin 5. The connecting rod 6 drives the cutting blade 10 to flip. The cutting blade 10 flips until it touches the stainless steel drinking water pipe, thereby cutting the stainless steel drinking water pipe. After the cutting is completed, lift the connecting rod 6 upward so that the connecting rod 6 is in a vertical state.

[0032] Compared with existing technologies, this device adjusts the height of the pressure plate 20 by rotating the threaded rod 22. The height of the pressure plate 20 is lowered to press and fix the stainless steel drinking water pipe, so that the stainless steel drinking water pipe can be cut. Compared with manual fixation, the fixing method of this device is more stable and avoids unnecessary safety hazards.

[0033] To avoid spending time searching for tools to tighten the threaded rod 22, the device only requires holding the anti-slip sleeve 13 and unscrewing the operating rod 12 from the first threaded hole 11. At this time, move the operating rod 12 so that the three insertion holes 15 at the bottom of the operating rod 12 are aligned with the herringbone-shaped slot 24 at the top of the threaded rod 22, so that the top of the threaded rod 22 is inserted into the inner cavity of the insertion hole 15. Then, hold the anti-slip sleeve 13 and rotate the operating rod 12, which will drive the threaded rod 22 to rotate. That is, the operating rod 12 of this device can not only be used to flip the extension handle of the cutting disc 10, but also as a tool to tighten the threaded rod 22. It has multiple functions, avoids workers spending time tightening the threaded rod 22, and improves work efficiency.

[0034] The herringbone-shaped slot 24 at the top of the threaded rod 22 can prevent unattended personnel from accidentally twisting the threaded rod 22 during the cutting process, which could cause the stainless steel pipe to loosen, thus avoiding unnecessary safety hazards and ensuring the normal progress of the cutting work.

[0035] To prevent the cutting disc 10 from tipping over when not in use, when the cutting disc 10 is finished or not in use, the connecting rod 6 is lifted upwards so that the connecting rod 6 is in a vertical position and fits against the left side wall of the base 1. The connecting ring 30 is then moved upwards, moving along the outer edge of the column 27. Simultaneously, the spring 29 is stretched, and the connecting ring 30 drives the first connecting plate 32 and the second connecting plate 35 to move upwards. The first connecting plate 32 drives the insert rod 33 to move, and the second connecting plate 35 drives the cylinder 36 to move, maintaining the upward force on the connecting ring 30. Then, the connecting ring 30 is rotated. The connecting ring 30 drives the spring 29 to rotate on the outer ring of the second bearing 28. The connecting ring 30 drives the insertion rod 33 to rotate together. When the insertion rod 33 rotates above the limiting hole 34, the connecting ring 30 stops rotating and then the upward force on the connecting ring 30 is slowly released. Under the elastic action of the spring 29 and the action of gravity, the connecting ring 30 and the insertion rod 33 move downward. The insertion rod 33 is inserted into the inner cavity of the limiting hole 34. At this time, the insertion rod 33 and the limiting hole 34 cooperate with each other to fix the fixing plate 4, preventing the fixing plate 4 and the connecting rod 6 as a whole from flipping down, thereby preventing the cutting disc 10 from flipping down when not in use.

[0036] When the cutting disc 10 is needed, the stainless steel pipe to be cut has been fixed by tightening the threaded rod 22 using the operating lever 12 as a tool. Then, hold the anti-slip sleeve 13 with one hand and move the connecting ring 30 upward with the other hand. The connecting ring 30 moves on the outer edge of the column 27, while the spring 29 is stretched. The connecting ring 30 drives the first connecting plate 32 and the second connecting plate 35 to move upward. The first connecting plate 32 drives the insertion rod 33 to move, and the second connecting plate 35 drives the cylinder 36 to move, maintaining the upward force of the connecting ring 30. Then, rotate the connecting ring 30. The connecting ring 30 drives the spring 29 to rotate on the outer ring of the second bearing 28. The connecting ring 30 drives the insertion rod 33 to rotate together. The connecting ring 30 drives the insertion rod 33 away from the limiting hole 34 through the first connecting plate 32, thereby releasing the connection. With the rod 6, fixing plate 4, and cutting blade 10 fixed, the cutting blade 10 can be flipped for cutting. Then, the connecting ring 30 continues to rotate. The connecting ring 30 drives the cylinder 36 to rotate above the threaded rod 22 via the second connecting plate 35. Then, the upward force on the connecting ring 30 is slowly released. The connecting ring 30 and the cylinder 36 move downward under the elastic action of the spring 29 and gravity. The cylinder 36 is fitted onto the outer top of the threaded rod 22. At this time, the cylinder 36 covers the slot 24. The rubber pad 37 on the top of the cylinder 36 fits against the top of the threaded rod 22. The rubber pad 37 increases the friction at the top of the inner cavity of the cylinder 36, which can prevent the threaded rod 22 from deflecting due to mechanical vibration during the cutting process, thereby preventing the clamped stainless steel tube from loosening and ensuring safety during the cutting process.

[0037] The connecting ring 30, insert rod 33, cylinder 36, column 27 and spring 29 work together to fix the cutting disc 10 when not in use, and also to fix the threaded rod 22 during the cutting process. Fixing the cutting disc 10 when not in use prevents it from flipping down. Fixing the threaded rod 22 prevents it from deflecting due to mechanical vibration during the cutting process, thus preventing the clamped stainless steel tube from loosening and ensuring safety during the cutting process.

Clearly, those skilled in the art can make various alterations and variations to the invention without departing from its spirit and scope.
