Detailed Description

Example 1

As shown in fig. 1-4, a PPR pipe chamfering device includes a body 1 and a connector 2, wherein two sides of the body 1 are respectively provided with a large pipe channel 3 and a middle pipe channel 4, the middle part is provided with a connecting block 5, two sides of the connecting block 5 are respectively fixed with a large pipe chamfering tool 6 and a middle pipe chamfering tool 7, the large pipe chamfering tool 6 and the middle pipe chamfering tool 7 are fixed in a manner that two sides of the connecting block 5 are respectively provided with a fixing hole, a cutter body 16 of the large pipe chamfering tool 6 and the middle pipe chamfering tool 7 is fixed in the fixing hole, when the fixing hole is fixed, the cutter body 16 can be properly coated with some glue to make them more firm, a blade 17 is exposed, the chamfer is convenient to cut, or the cutter bodies 16 of the large pipe chamfering tool 6 and the middle pipe chamfering tool 7 can be fixed on two sides of the connecting block 5 in a manner of screw fixation, the large pipe channel 3 and the middle pipe channel 4 are respectively provided with a scale wire 8, the graduated scale is a linear scale line arranged on the body 1 on the large pipe channel 3 and the middle pipe channel 4, which is convenient for determining the installation length after cutting the chamfer of the large pipe and the middle pipe, and realizes accurate installation, the body 1 at the outer end of the large pipe channel 3 is provided with a slot 9, the connector 2 is provided with an insert 10, the slot 9 is matched with the insert 10, the inner end of the connector 2 is provided with a fixed block 11, a small pipe chamfer cutter 12 is fixed in the fixed block 11, the fixing of the small pipe chamfer cutter 12 can also adopt that a fixed hole is arranged in the fixed block 11, the cutter body 16 of the small pipe chamfer cutter 12 is inserted into the fixed hole for fixing, when the fixed hole is fixed, some glue can be properly coated on the cutter body 16, so that the cutter body is firmer, the blade 17 is exposed, the chamfer is convenient to cut, and can also be fixed by adopting a screw mode, the small pipe channel 14 is arranged in the connector 2, the outer end of the connector 2 is provided with a scale groove 15, the scale groove 15 is a linear groove formed in the connector 2 at the outermost end of the small pipe channel 14, the installation length can be conveniently determined after the small pipe is cut, and accurate installation is achieved.

The body 1 is an injection molding body, so that the weight is reduced, and the strength is maintained.
