Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting, in particular to a pipe cutting device for water and electricity installation. Background Art

[0002] During the interior decoration process, workers need to use pipes to connect water lines and wrap cables. Commonly used pipes in water and electricity installations include PVC pipes, PPR pipes, cast iron pipes, and stainless steel pipes. Using appropriate pipe selection can effectively ensure the quality and reliability of water and electricity installations. When connecting water lines and wrapping cables, various pipes of different lengths are required. This requires the use of pipe cutting devices to cut longer pipes so that their length can adapt to construction requirements.

[0003] Traditionally, pipe cutting involves manually fixing both ends of the pipe and then cutting with a handheld cutter. This is not only inefficient, but hand shaking during cutting can lead to inaccurate pipe cutting or tilted cross-sections, requiring subsequent trimming, which severely reduces overall cutting efficiency.

The output shaft of the motor 4 will drive the second gear 3 to rotate, and the rotation of the second gear 3 will drive the first gear 1 to rotate. The rotation of the first gear 1 will make the connecting rod 6 slide in the arc-shaped chute 5, and the three connecting rods 6 will approach each other. The three connecting rods 6 will drive the square plate 10 to approach the pipe. The movement of the square plate 10 will drive the sliding plate 9 to move in the square groove 8. The square plate 10 will drive the round rod 11 to move close to the pipe. The round rod 11 The movement will drive the arc-shaped clamping plate 12 to move closer to the pipe until the anti-slip pad and the arc-shaped clamping plate 12 tightly clamp the pipe, and then the cutting machine 16 can be used to cut the pipe, which effectively solves the problem that the traditional cutting proposed in the background technology is to manually fix the two ends of the pipe and then cut with a hand-held cutter, which is not only inefficient, but also the hand shaking during cutting causes the pipe cutting accuracy to be insufficient or the cross-section to be tilted, requiring subsequent removal, which seriously reduces the overall cutting efficiency, thereby achieving the technical effect of improving the accuracy of pipe cutting and ensuring the efficiency of the overall cutting work.

[0022] In the utility model, a limiting plate 22 is fixed on the side of the second gear 3 away from the motor 4, and the outer wall of the limiting plate 22 is rotatably sleeved with a first fixed plate 17.

[0027] Working principle: When using this device, the pipe can be placed in the circular groove 2, and then the motor 4 is started. The output shaft of the motor 4 will drive the second gear 3 to rotate, and the rotation of the second gear 3 will drive the first gear 1 to rotate. The rotation of the first gear 1 will cause the connecting rod 6 to slide in the arc-shaped groove 5, and the three connecting rods 6 will approach each other. The three connecting rods 6 will drive the square plate 10 to approach the pipe. The movement of the square plate 10 will drive the sliding plate 9 to move in the square groove 8, and the square plate 10 will drive the round rod 11 to move close to the pipe. The movement of the round rod 11 will drive the arc-shaped splint 12 to move close to the pipe until the anti-slip pad and the arc-shaped splint 12 tightly clamp the pipe, and then take out the insertion rod 21. If the first gear 1 continues to rotate, the first gear 1 will squeeze the connecting rod 6 and drive the connecting rod 6 to do circular motion with the first gear 1 as the center, and the connecting rod 6 will drive the square plate 10 to move with the first gear 1 as the center of the circle to make a circular motion, the square plate 10 will drive the sliding plate 9 and the round rod 11 to make a circular motion with the first gear 1 as the center of the circle, and the sliding plate 9 will drive the ring 7 to rotate. Through the mutual cooperation of the limiting slider 13 and the limiting slot 23, the ring 7 will not deviate during rotation. Through the mutual cooperation of the annular slot 14 and the annular slider 15, the positions of the first gear 1 and the ring 7 will not deviate. When the round rod 11 rotates, it will drive the arc splint 12 and the anti-slip pad to make a circular motion with the first gear 1 as the center of the circle, and the arc splint 12 and the anti-slip pad will drive the pipe to rotate. At this time, the cutting machine 16 can be started and pushed to make it close to the pipe to cut the pipe. The connecting rod 6 is continuously squeezed by the first gear 1, and the arc splint 12 and the anti-slip pad will not loosen the pipe. After cutting, the output shaft of the motor 4 can be rotated in the opposite direction to loosen the pipe.
