Embodiment Construction

[0019] The present invention will be further described below in conjunction with the embodiments of the accompanying drawings.

[0020] Such as figure 2 , image 3 As shown, a pipe expansion installation tool includes a pipe expansion head 2 installed at the front end of the pipe expansion tool 1. The expansion head 2 extends from the inside to the outside with more than four expansion pipe splits 20. When the expansion pipe splits The expansion tube action part 21 of 20 is provided with an elastic ring 3, and also includes a flexible rubber sleeve 4, and the rubber sleeve 4 wraps all the expansion tube splits 20 to limit the position; the expansion tube splits 20 There is a chamfer 22 structure between them to prevent the rubber sleeve 4 from being pinched; the steps of the expansion tube split 20 are also rounded corner structures 25; the rubber sleeve 4 wraps the front end part 23 of the expansion tube split 20 at the same time Reserving the opening portion 40; the wrapp...

Abstract

The invention relates to the field of installation of construction pipelines, in particular to an installation tool for expansion of pipeline nozzles. A pipe expansion installation tool, including a pipe expansion head installed at the front end of the pipe expansion tool. The pipe expansion head extends from the inside to the outside with more than four expansion pipe splits. The elastic ring also includes a stretchable rubber sleeve, and the rubber sleeve wraps and limits all the expansion tube splits; the surface of the expansion tube splits is provided with a chamfer structure and a rounded corner structure. On the basis of the prior art, the present invention wraps the limited expansion tube split valves with rubber sleeves, adjusts the expansion tube split structure, solves the problem of the expansion tube split valves warping and detachment at the expander head, and greatly improves the performance of the expansion tubes. The service life and durability of the head are improved, and the uniformity of pipe expansion is further improved, the beneficial effect is obvious, and it has market promotion value.

Description

technical field [0001] The invention relates to the field of installation of construction pipelines, in particular to an installation tool for expansion of pipeline nozzles. Background technique [0002] Pipes such as aluminum-plastic pipes, cross-linked polyethylene pipes, and high-temperature-resistant polyethylene pipes are widely used in domestic hot and cold water and household heating pipes. This type of flexible pipe itself is moderately flexible and has ductility. It adopts the announcement CN 202612934 U " The pipe fitting connection shown in "Connection Structure of Flexible Pipe Sliding and Tight Fittings" has the advantages of large flow rate at the joint, good hydraulic performance, safety and reliability. The flexible pipe is installed by sliding tight pipe fittings. In the twelfth paragraph of the specification of the above-mentioned patent, it is described that "the end of the flexible pipe is slightly opened by means of mechanical tools, so that the end of t...
