Description

Technical Field

[0001] The utility model belongs to the technical field of pipe cutting, in particular to a pipe cutter. Background Art

[0002] In the field of pipe cutting, traditional cutting methods mainly include handheld saw cutting and electric cutter cutting. Handheld saw cutting of pipes is completely dependent on manual operation, and the saw blade is prone to breakage during the cutting process. When using an electric cutter to cut pipes, its working conditions are subject to certain restrictions and require an adjacent power supply. In addition, sparks are generated during the cutting process, which increases the risk of fire, especially in flammable environments. On the other hand, the debris generated by the cutting is scattered everywhere. If the operator does not wear protective equipment such as goggles, it is very easy to cause damage to important body parts such as the eyes, posing a major safety hazard. Utility Model Content

[0011] In order to make the purpose, technical solutions and advantages of this application more clear, the present invention will be described in further detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0012] It should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this patent.

[0013] Figure 1 This is a schematic diagram of the main structure of a pipe cutter according to an embodiment of the present utility model.

[0014] Reference Figure 1According to an embodiment of the present invention, a pipe cutter includes: a feed pipe 1, a moving device 2, multiple groups of rotating components 3 and a cutting blade 4. A feed cavity 11 for carrying a pipe 5 is provided in the feed pipe 1. The fixed end of the moving device 2 is fixedly connected to the outer periphery of the feed pipe 1, and the movable end of the moving device 2 penetrates into the feed cavity 11, and the movable end of the moving device 2 is fixedly connected to the cutting blade 4. The outer peripheral surface of each group of rotating components 3 abuts against the pipe 5 to clamp the pipe 5 between each group of rotating components 3 and the cutting blade 4. When cutting the pipe 5, the moving device 2 and each group of rotating components 3 jointly clamp the cutting blade 4 and rotate along the outer peripheral surface of the pipe 5, thereby cutting the pipe 5.

[0015] Specifically, the moving device 2 includes: a screw rod 21, a handle 22, a fixed shaft 23, an upper nut 24, a lower nut 25 and a first bearing seat 26. The outer peripheral surface of the screw rod 21 is connected to the upper nut 24 and the lower nut 25 respectively through threads, thereby forming a vertical downward stable state in the fixed shaft 23. One end of the screw rod 21 is fixedly connected to the handle 22 after passing through the upper nut 24 and the lower nut 25 respectively, and the other end of the screw rod 21 is fixedly connected to the cutting blade 4 through the first bearing seat 26. The fixed shaft 23 is fixedly connected to the feed pipe 1, the axis of the fixed shaft 23 is perpendicular to the axis of the feed pipe 1, and the outer sides of the upper nut 24 and the lower nut 25 are fixedly connected to the inner surface of the fixed shaft 23. When the screw rod 21 rotates, the screw rod 21 moves up and down in the fixed shaft 23, thereby changing the position of the cutting blade 4, thereby further increasing the force of the cutting blade 4 during the cutting process of the pipe 5.

[0016] Specifically, each rotating assembly 3 comprises multiple rotating shafts 32 and roller assemblies 32. Each rotating shaft 32 is fixed to the outer circumference of the feed tube 1, and each rotating shaft 32 is equipped with a corresponding roller assembly 32. Each roller assembly 32 includes multiple rollers 321 of equal size. Each roller 321 within the same roller assembly 32 is mounted on the same rotating shaft 32 and coaxially connected. The roller assemblies 32 of different groups are symmetrically arranged about the axis of the fixed shaft 23.

[0017] Furthermore, in this embodiment, there are two sets of rotating assemblies 3. The outer circumference of the feed tube 1 is formed with multiple retaining grooves 12 corresponding to each set of rotating assemblies 3. Portions of each roller 321 are respectively inserted into corresponding retaining grooves. The retaining grooves 12 are symmetrically arranged about the axis of the fixed shaft 23.

[0018] During the cutting process of the pipe 5, after the operator inserts the pipe 5 into the feed pipe 1, the outer circumference of the pipe 5 abuts against the outer circumference of each roller assembly 32. The relative position of the cutting blade 4 and the pipe 5 is adjusted so that the pipe 5 is clamped between the cutting blade 4 and each roller assembly 32. The handle 22 is rotated along the circumference of the feed pipe 1, causing the feed pipe 1 and each rotating assembly 3 to rotate along the outer circumference of the pipe 5. The pressure generated by the cutting blade 4 and each rotating assembly 3 causes the cutting blade 4 to cut the pipe 5 along the outer circumference. The debris generated during the cutting process is retained within the feed pipe 1 by the wall of the feed pipe 1, thus preventing the debris from injuring others.

[0019] To sum up, the utility model drives the pipe to rotate through the rotating component, and the moving device adjusts the position of the cutting blade in the feed pipe, changes the pressure generated by the joint action of the cutting blade and the rotating component to cut the pipe without power supply, and makes the debris generated during the cutting process blocked by the wall of the feed pipe to avoid the debris from hurting people.
