Abstract
The utility model provides a quickly inserted flexible pipe quick coupling which comprises a flat nut, a screw body and a clamping sleeve. The flat nut is connected with a screwed joint on the left side of the screw body, an annular groove is formed in the right side of the screw body, positions, axially symmetrical to the annular groove, of the upper portion and the lower portion of the annular groove are provided with hollow-out portions which are identical in size and shape, the clamping sleeve is an annular sleeve with an unclosed opening, and the inner wall of the clamping sleeve is provided with an annular protrusion matched with the annular groove in the screw body. The quickly inserted flexible pipe quick coupling has the advantages of being simple in structure, convenient to install and low in processing cost.
Description
Technical field
The utility model belongs to the pipe joint field, especially relates to a kind of push-in gladhand.
Background technique
Metallic 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.Metallic hose generally is made of corrugated stainless steel tubing, stainless steel net and joint, and joint then comprises inipple and flanged joint, and fixed and movable dividing arranged.Existing metallic hose is that the end face of bellows, net is direct and joint is integrally welded.The metallic 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 welding zone produces extra heat stress in addition, the force-bearing situation of weld joint is worsened, and flexible pipe is in dynamically lower work, bears alternating stress, and fatigue ruption just more easily occurs weld.
So how to improve the ability of sealing anti-leak of the sealability under different operating modes, particularly joint of metal pipe element, this becomes one of urgent problem in the prior art.
Summary of the invention
Problem to be solved in the utility model provides a kind of push-in gladhand.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: push-in gladhand, comprise flush nut, breechblock and chucking cover, it is characterized in that: described flush nut is connected with the inipple in described breechblock left side, described breechblock right side has annular groove, upper and lower on the described annular groove and described annular groove axially have the identical hollow out of size and shape in symmetrical position, described chucking cover is for having the inc annular cover of an opening, described chucking cover inwall have with described breechblock on the annular protrusion that is complementary of described annular groove.
It is protruding high that the described annular protrusion of convexity that described hollow out on described annular protrusion and the described annular groove is complementary and the non-described hollow out on the described annular groove are complementary.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, have simple in structurely, processing cost is low, etc. advantage.
