Description

Technical Field

[0001] This utility model belongs to the field of pipe cutter technology, specifically referring to a large-diameter pipe cutter for plastic pipes. Background Technology

[0002] Currently, most pipe cutters on the market have circular channels for connecting the clamping seat. When cutting plastic pipes, such channels require the pipe to be squeezed hard, and cannot be adjusted according to the actual situation of the pipe. This not only reduces the efficiency of pipe cutting but also reduces the flatness of the pipe cut. Furthermore, prolonged use can easily damage the pipe cutter and affect its service life. Utility Model Content

[0003] The purpose of this invention is to provide a large-diameter pipe cutter for plastic pipes that has a stable structure, high cutting efficiency, and long service life.

[0004] The purpose of this utility model is achieved as follows: A large-diameter pipe cutter for plastic pipes includes a clamping device and a pipe cutting device slidably disposed on the clamping device. The clamping device includes a left clamping member and a right clamping member connected to the pipe cutting device. The left and right clamping members are rotatably disposed by screws. Both the left and right clamping members have elliptical channels. A left clamping seat and a right clamping seat are rotatably disposed in the two elliptical channels respectively. Both the left and right clamping seats have extensions installed in the elliptical channels. Several through holes are opened on the extensions, and ball bearings are disposed in the through holes.

[0005] Preferably, both the left clamping seat and the right clamping seat are formed with a limiting strip 1. The limiting strip 1 abuts against one side of the left clamping member and the right clamping member, and the other side of the left clamping member and the right clamping member abuts against a limiting strip 2. The two limiting strips 2 are respectively connected to the left clamping seat and the right clamping seat by screws.

[0006] Preferably, a limiting block is formed at the lower end of the right clamping member, and the limiting block abuts against the left clamping member.

[0007] Preferably, the lower end of the right clamping seat is formed with a limiting block two, which abuts against the left clamping seat.

[0008] Preferably, the clamping device further includes several clamping components that are snapped onto the left clamping seat and the right clamping seat.

[0009] The outstanding and beneficial technical effects of this utility model compared with the prior art are as follows: The large-diameter pipe cutter of this utility model sets the internal channel of the clamping device into an elliptical shape, which allows the ball bearings to be finely adjusted within the channel. This makes it convenient to use pipes of different specifications. During cutting, the clamping seat can be adjusted, which increases the cutting efficiency and the service life of the pipe cutter.

[0013] Figure 4 This is an exploded view of this utility model. Detailed Implementation

[0014] The present invention will be further described below with reference to specific embodiments.

[0015] like Figure 1-4 As shown, a large-diameter pipe cutter for plastic pipes includes a clamping device 1 and a pipe cutting device 2 slidably mounted on the clamping device 1. The clamping device 1 includes a left clamping member 3 and a right clamping member 4 connected to the pipe cutting device 2. The left clamping member 3 and the right clamping member 4 are rotatably mounted by screws. Both the left clamping member 3 and the right clamping member 4 have elliptical channels 5. A left clamping seat 6 and a right clamping seat 7 are rotatably mounted in the two elliptical channels 5, respectively. Both the left clamping seat 6 and the right clamping seat 7 have extensions 8 installed in the elliptical channels 5. The extensions 8 have several through holes 9, and each through hole 9 has a ball bearing 10.

[0016] The large-diameter pipe cutter for plastic pipes in this technical solution allows the ball bearings to be finely adjusted within the elliptical channel of the clamping device 1, making it suitable for pipes of different specifications. During cutting, the clamping seat can be adjusted to increase cutting efficiency and extend the service life of the pipe cutter.

[0017] Preferably, both the left clamping seat 6 and the right clamping seat 7 are formed with limiting strips 11. The limiting strips 11 abut against one side of the left clamping member 3 and the right clamping member 4, and the other side of the left clamping member 3 and the right clamping member 4 abuts against limiting strips 22. The two limiting strips 22 are respectively connected to the left clamping seat 6 and the right clamping seat 7 by screws. The limiting strips 11 and 22 fix the left clamping member 3 and the right clamping member 4, preventing them from moving left or right and affecting the flatness of the pipe cutting.

[0018] Preferably, the lower end of the right clamping member 4 is formed with a limiting block 13, which abuts against the left clamping member 3. The limiting block 13 ensures the angle of the left clamping member 3 and the right clamping member 4 when they are open, facilitating faster gripping of the pipe and increasing cutting efficiency.

[0019] Preferably, the lower end of the right clamping seat 7 is formed with a limiting block 2 14, which abuts against the left clamping seat 6. The limiting block 2 14 ensures the angle of the left clamping seat 6 and the right clamping seat 7 when they are open, facilitating faster clamping of the pipe and increasing cutting efficiency.

[0020] Preferably, the clamping device 1 further includes several clamping elements 15 that are snapped onto the left clamping seat 6 and the right clamping seat 7. By setting clamping elements 15 of different specifications, the pipe cutter can adapt to pipes of different specifications, increasing its application scenarios.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
