Description

Novel internal thread joint structure form for tap water pipe connection

Technical Field

The utility model relates to, in particular to a novel structural form of an internal thread joint for connecting a tap water pipe,

background

Internal thread joints for external connection of running water pipes in the market are mostly cast I-shaped connectors, and the joints need to be fixed by pipe tongs during connection, so that the installation is inconvenient, and time and labor are wasted; the surface has more sand holes, and the surface of the thread is rough after tapping; the sealing performance is insufficient, and a raw adhesive tape needs to be wound during connection, so that the sealing performance is improved; and is inconvenient to use cold heading equipment for mass production with high efficiency and low cost.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a new structure of female adapter for connecting a tap water pipe to solve the above problems of the related art.

In order to achieve the purpose, the utility model provides the following technical scheme:

a new structural form of an internally threaded joint for connecting a tap water pipe is characterized by comprising a joint body 1 and a joint side end surface 3.

An end face chamfer 2 is arranged at the joint of the joint main body 1 and the joint side end face 3, the joint main body 1, the end face chamfer 2, the joint side end face 3, the inner eighteen-tooth structure 13 and a preformed hole needed by the internal thread 11 are directly formed by a cold heading process, and then the internal thread 11 is formed by tapping.

The internal thread 11 is provided with an opening chamfer 12 at the opening to play a role in guiding and positioning.

Compared with the prior art, the utility model has the following beneficial effects:

1. the production process of cold heading and tapping is adopted, so that the thread quality and the production efficiency are improved; and the installation efficiency is improved by adopting an inner hexagonal pattern.

2. Cold heading is a production mode for removing excess materials by extrusion deformation. The size and shape of the produced product are ensured by the die, secondary clamping is not needed, the efficiency is high, and the consistency is good.

3. The thread precision after tapping of the cold heading product is consistent with that of the lathed product, and a raw adhesive tape does not need to be wound during sealing.

4. The inner eighteen teeth form is adopted, the space limitation is small, the installation can be tightened by only using a hexagonal wrench, and the operation is more convenient and quicker.
