Novel external thread loose joint device

Abstract

A novel external wire loose joint device comprises a connecting head and a connecting cavity. The connecting head is connected with the connecting cavity. A connecting pipe is connected with the rear portion of the connecting cavity. A sleeving component is arranged outside the connecting cavity. A cushion layer is arranged between the sleeving component and the connecting cavity. A fixing screen is arranged in the connecting cavity. A protective layer is arranged outside the fixing screen and is a copper protective layer. A protective layer is arranged in the loose joint device and capable of protecting the inner side of the loose joint device from being corroded by conveyed matter, and the actual working effect of the loose joint device can be guaranteed; and the connecting pipe is arranged in the loose joint device, connection of the loose joint device and a hose can be facilitated, the connecting time is short, the connecting effect is good, connection of the loose joint device and other pipe fittings is improved, and the connecting efficiency is improved.

Description

Technical field [0001] The invention relates to a joint, in particular to a new type of outer wire live joint device. Background technique [0002] A large number of joints need to be used in construction. Joints can play a role in connection and transmission, and can directly transmit the materials that need to be transmitted to the pipe network. However, many joints are not convenient to install when they are used. It takes a lot of time during the installation process, which affects the installation efficiency of the joint, and some joints have insufficient corrosion resistance when in use, and the inner wall of the joint is corroded seriously, which affects the use of the joint. Summary of the invention [0003] The purpose of the present invention is to provide a new type of outer wire live connection device with good corrosion resistance and convenient connection. [0004] The technical solution of the present invention is: a new type of outer wire live connection device, com...
