Description
Technical field
The utility model relates to hose connections, are in particular a kind of effective integral type attaching type connectors of cotton thread.
Background technique
It is the usual way of hose connection using Pigeonhole type hose joint.The general hose coupling sheet of Pigeonhole type hose joint
Body, sleeve and locking nut；In use, one end with locking nut with machinery equipment for being detachably connected；The other end is soft
For being inserted in hose, sleeve covers outside hose pipe fitting ontology, and uses special equipment clamp sleeve, so that hose is compressed
On hose coupling ontology.But traditional cotton thread pipe thread crimp head when withholding exist assemble it is cumbersome, withhold position should not be true
Fixed, anti-pulling-and-doffing performance can lower, easily weigh cotton thread pipe wounded, withhold the problems such as set materials are more.
Summary of the invention
It positional accuracy is withheld, improves connector anti-pulling-and-doffing performance to improve, avoid weighing wounded cotton thread pipe, save and withhold set materials,
The utility model provides a kind of effective integral type attaching type connector of cotton thread.By the internal junction for changing integral type attaching type connector
Structure, assemble sequence and withhold sequence, indirectly change integral type attaching type connector and cotton thread pipe contact surface construction, not only provide whole
The simplicity of body installation, avoids cotton thread pipe from being weighed wounded, saves and withhold set materials, while improving versatility and anti-pulling-and-doffing performance, withhold
Accuracy, the reliability and safety of connection.
Including locking nut, hose coupling ontology, plastics retaining ring, withhold set, the described set of withholding is for by cotton thread pipe pressure
Tightly on hose coupling ontology；It is characterized in that the described set of withholding includes pre- buckle section and buckle section, pre- buckle section and withhold
Section and between withhold line, the line of withholding is to withhold the shallow annulus together on set outer wall；The pre- buckle section end
There is inside annular flange in position, there is groove corresponding with annular flange on the hose coupling ontology；It is described pre- to withhold
Section is close to plastics retaining ring；At least two annular protrusions on the buckle section inner wall；Have one on the hose coupling ontology
A first annular slot and at least one second annular groove, first annular slot are more shallow than the second annular groove；The first annular slot and
Second annular groove annular groove location is opposite with the upper annular protrusion of set is withheld.
It is arc-shaped, 1.4-1.7mm of arc radius, crown height 0.6-as the preferably described annular protrusion
1.1mm, circular arc and withhold set 0.3-0.7mm of intersection chamfering；The first annular slot and the second annular groove is dovetail groove,
0.3-0.7mm of notch and trench bottom chamfering；2.5-2.9mm of first annular slot width of rebate, slot bottom width 1.8-
2.2mm；Second annular groove width of rebate is identical with first annular slot width of rebate, slot bottom width 1.1-1.8mm.
The utility model advantage: the utility model has assembly simple, and cotton thread pipe is avoided to be weighed wounded, and saving, which is withheld, applies
Material, it is accurate to withhold position, and anti-pulling-and-doffing performance can higher advantage.
1, assembly is easy: when production, by hose coupling ontology, plastics retaining ring, withhold pack into luggage with and make-up pressing sleeve
Pre- buckle section is withheld.Later, above-mentioned component is assembled with cotton thread pipe again as a whole, assembles simple and convenient standard
Really.
2, it is accurate to withhold position: snap-fastener crimping position is withheld when withholding, and ensure that the accuracy for withholding position, is improved
Withhold the quality and efficiency of process.
3, anti-pulling-and-doffing performance can it is higher, avoid cotton thread pipe from being weighed wounded: on hose coupling ontology first annular slot and second annular
Trapezoidal thread form I, IV of slot and the semicircle thread form for withholding collar-shaped protrusion can preferable male-female engagements.Outer diameter D 1 is greater than outer simultaneously
Diameter D2 in outer diameter D3, is withheld under the semicircle thread form and the identical situation of outer diameter of set, and after withholding, cotton thread pipe is in first annular slot
The pressure being subject to is greater than the pressure being subject at the second annular groove.The larger pressure that first annular slot is subject to is conducive to preferably close
Envelope and resistance to plucking are de-；The upper thread layer for being avoided cotton thread pipe by smaller pressure at second annular groove is pressed down.Meanwhile trapezoidal thread form energy
Preferably with withhold set cooperation, avoid the inner glue layer pressure break of cotton thread pipe.
4, it saves and withholds set materials: in use, since the pre- buckle section of first make-up pressing sleeve is withheld.Withhold withholding for set
Pressure section withholds outer diameter of the rear outer diameter lower than buckle section, and withholding the steel pipe material stock thickness selected when set processing reduces very much, saving
Materials.

Specific embodiment
The use of the new type is further detailed with reference to the accompanying drawing:
The utility model includes locking nut, hose coupling ontology 1.1, plastics retaining ring 1.2, withholds set 1.3, the button
Pressing sleeve 1.3 is used to cotton thread pipe 2 being pressed on hose coupling ontology 1.1；The set 1.3 of withholding includes pre- buckle section and button
Press section, pre- buckle section and buckle section and between withhold line 1.3.1, the line 1.3.1 that withholds is on withholding 1.3 outer walls of set
Together shallow annulus；
The pre- buckle section tip position has inside annular flange, has on the hose coupling ontology 1.1 and ring
The corresponding groove of shape flange；
