Abstract
The utility model provides a grounding pipe joint, comprising a screwed body, a nut, a sun ring and a sheath. The screwed body comprises a holding portion in the middle and connection portions in two sides of the holding portion, wherein the connection portions are different in internal diameters, and are equipped with outside threads; the nut and the sun ring are respectively arranged at two ends of the screwed body and in threaded connection with the connection portions (14), wherein projections are respectively arranged in upper and lower sides of the nut; and the sheath is arranged in the screwed body, and comprises an annular groove, wherein a circle of outside screw threads is arranged in end portions of the inner wall of the annular groove, and the sheath contacts with an annular platform in the screwed body via the bottom of an annular groove. The grounding pipe joint has the advantages of simple structure, simple operation and easy for connection.
Description
Technical field
The utility model belongs to the pipe joint field, especially relates to a kind of ground pipe joint.
Background technology
Metal hose is widely used in numerous industries such as military project, oil, chemical industry, electric power, metallurgy, printing and dyeing, papermaking and heating for residential area, building.Metal hose generally is made of corrugated stainless steel tubing, stainless steel net and joint, and joint comprises nipple and bump joint, and fixed and movable dividing arranged.Existing metal hose is that the end face of bellows, net is direct and joint is integrally welded.The metal hose force-bearing situation of this welded fitting is bad, because the weld Components Shape is undergone mutation, bellows tube wall and joint thickness difference are large, cause that stress is concentrated, expanding with heat and contract with cold of weld zone, produce extra heat stress in addition, the force-bearing situation of commissure is worsened, and flexible pipe is in dynamically lower work, bears alternate stress, and fatigue rupture just more easily occurs weld.
The utility model provides a kind of ground pipe joint for electric utility cable protection pipe and equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, simple to operate, ground pipe joint of being easy to connect.
The technical solution of the utility model is:
The ground pipe joint, comprise breechblock, described breechblock in the middle of comprising handle part and be positioned at the different inner diameters size of described handle part both sides and with externally threaded connecting portion, the nut and the sun ring that are positioned at described breechblock two ends and all are threaded with the connecting portion 14 of described breechblock, the both sides up and down of described nut are provided with projection, described breechblock inside is placed with sheath, described sheath comprises cannelure, and the inwall end of described cannelure is provided with a button external screw thread, and described sheath contacts with ring-shaped platform in described breechblock by the bottom of cannelure.
Further, also be provided with lining cylindraceous in described breechblock, described lining one side contacts with annular protrusion on described breechblock inwall.
Further, be provided with sealing ring between the handle part in the middle of described sun ring and described breechblock.
Further, be provided with grommet between described nut and described hose sheath.
The advantage that the utlity model has with good effect is connected: simple in structure, simple to operate, be easy to connect.
