Metal female water connection with convenient equipotential bonding

Abstract

The invention relates to a metallic inner-thread water pipe joint facilitating equipotential line connection. The metallic inner-thread water pipe joint comprises a water pipe joint, wherein a metallic internal-thread joint is arranged in the water pipe joint through integral injection molding, a metallic bump is integrally formed on the outer side surface of the metallic internal-thread joint, a tightening thread hole is formed in the outer end surface of the metallic bump in an axial direction, and a connection hole communicated with the inner end of the tightening thread hole is formed in the outer side surface of the metallic bump in a radial direction; during using, one end of a wire extends into the connection hole, the tightening wire is screwed into the tightening thread hole by a tightening screw, and the other end of the wire is connected with an equipotential device which is pre-embedded into the wall and is grounded. The connection structure is safe and reliable, the wire is not prone to falling off, and human body electric-shock safety accidents caused by electric leakage of an electric heater in a toilet, thunder and lightning, static electricity and the like are effectively prevented. The metallic inner-thread water pipe joint is firm in connection, safe, attractive, low in processing cost, easy to operate and suitable for being used on a plastic water pipe fitting.

Description

technical field [0001] The invention relates to the field of house decoration, in particular to a metal inner tooth water pipe joint with convenient equipotential line connection. Background technique [0002] The resistance of the human body will become smaller when the body is wet. As long as the low voltage passes through the wet human body, electric shock may occur. Therefore, when the electric heater leaks electricity, or when lightning or static electricity occurs, there is a great hidden danger to the safety of the human body. my country's decoration industry has issued relevant regulations, stipulating that equipotential mandatory installation should be implemented in the toilets of new buildings. [0003] In the prior art, there are various equipotential installation technologies. For example, the prior art discloses a water pipe fitting with an equipotential terminal with the application number 201520314037.1. Its structure is that a metal bush is embedded in the p...

Problems solved by technology

But this connection structure has the following disadvantages: the outer protrusion of the pipe fitting body of this structure is provided with a wiring hole for connecting wires, and the connection mode in which the wires are wound through the perforations is not firm, and it is easy to get off the wire. Outside the outer surface of the pipe fitting body, it looks abrupt and unsightly, and the embedded conductive strips appear to have a complicated structure and high processing cost

The wire is fixed on the outer terminal with screws. The fixing method is that the wire is wound on the screw first, and then the screw is screwed into the inner terminal. In this connection, the wire is easy to fall off, not firm and not beautiful, and the wire is easy to fall off and cause electric shock accidents
