Description
Technical field
The utility model is related to a kind of screw-type connectors of hose.
Background technology
At the production operation scene of enterprise, often there are some equipment using gas or liquid-working-medium, the conveying of medium
Pipeline uses hose, the phenomenon that connection use of all kinds of high and low pressure hoses is a kind of commonplace, especially with oxygen, combustion gas,
Compressed air and nitrogen, hydrogen, argon, carbon dioxide etc. are even more so for the hot-working unit of working media.The connection side of hose
Formula is generally all using iron wire binding or pipe collar (including being squeezed into pattern pipe collar and screw tension-type pipe collar) connection, this three kinds connections
The common feature of mode is that tied or banding hose is made to generate internal withdraw type crimp, by the inner surface or inner tube of hose
Inner surface, it is anti-slip between tube core (back taper surface pipe joint or smooth straight connector with concentric reducer diameter) outer surface with being connected
Frictional resistance realizes sealing and connection, and attachment force only results from pipe internal surface, in the case of without using special tooling, instrument
Its bonding strength, leakproofness are not easy to ensure, easily leak or even come off, and charge and discharge operations are cumbersome, laborious.
Utility model content
The utility model problem to be solved is in view of the above shortcomings of the prior art, and to provide a kind of screw thread of hose
Formula connector.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of screw-type connector of hose, including joint pipe body and two nut sets, joint pipe body is in hollow cylinder,
Both ends are respectively equipped with 1 socket changeover portion, are socketed that the section of changeover portion is tapered, and small end is super outer, be socketed changeover portion outside
Periphery is equipped with the anti-skidding sawtooth of rigidity, and the saw cutting edge of a knife or a sword of the anti-skidding sawtooth of rigidity is towards the center of joint pipe body, the inner circle of nut set
Circumferential surface is divided into taper surface section, planar section and thread segment vertically, and the big end of taper surface section is towards the center of joint pipe body, taper surface
The taper of section is adapted with being socketed the taper of changeover portion, and planar section is equipped with rubber antiskid sawtooth, and the saw cutting edge of a knife or a sword of rubber antiskid sawtooth is equal
Towards the center of joint pipe body, thread segment is equipped with internal thread, and corresponding position is equipped with external screw thread, screw thread on the outer circumference surface of joint pipe body
The internal thread of section is adapted with the external screw thread of joint pipe body.
The outer diameter of changeover portion big end is socketed equal to the diameter in the middle part of joint pipe body.
The outer circumference surface of nut set is equipped with faceted pebble.
The width of taper surface section is less than or equal to the width of socket changeover portion.
The width of thread segment is more than or equal to the 1/3 of nut set width.
Compared with prior art, the beneficial effects of the utility model are：In use, two hoses are first screwed in into joint pipe body
Both ends, rotate to anti-skidding sawtooth, two clips be stuck in outside hose respectively at corresponding annular clamping portion, are then revolved clip
It, need not be in use, the clip that comes loose, installation and removal conveniently, operate letter to most can tightly link up two section hoses
Just, it is laborsaving, and be not easy to leak, it is less easy to fall off.
Description of the drawings
Fig. 1 is the structure diagram of the screw-type connector of the hose of the utility model.
Wherein, 1- joint pipe bodies,
2- nut sets,
3- is socketed changeover portion,
4- taper surface sections,
