It is obtained by, also achieves the call of national energy-saving reduction of discharging.Hydraulic system is integrated to be increased, and hydraulic fluid port is more and more tightr, installs empty
Between it is more compact, currently used for the connector in Hydraulic Power Transmission System or general pipe-line system mostly be using threaded connection or
Flange form connects, be restricted using screw thread or flange connection in such space it is bigger because above two connector
Install, tighten, dismantling etc. and being both needed to larger space and just can complete, and installation effectiveness is relatively low, coupler bore is less, and flow is little, tool
There is the larger pressure loss.
The content of the invention
The purpose of this utility model is for deficiencies of the prior art, there is provided a kind of fast insertion type joint, and it has
Have that installing space is little, installing/dismounting efficiently advantage, with preferable applicability, and flow is big, the pressure loss is little.
To reach above-mentioned purpose, a kind of fast insertion type joint of the present utility model, including the male connector body for being equipped with endoporus and
Female connector body；It is characterized in that being provided with closure gasket groove on the endoporus of female connector body, seal is provided with closure gasket groove, in sealing
Endoporus in front of annular groove is provided with connected annular groove and taper hole, and taper hole is located at annular groove front, and the internal diameter of taper hole is pre-small post-large, annular groove
External diameter be more than taper hole, in the annular groove and taper hole, elastic steel wire check ring is provided with fracture, the width of annular groove to an elastic steel wire check ring
More than the external diameter of elastic steel wire check ring, the external diameter of elastic steel wire check ring is more than the front end path of taper hole；At the middle part of male connector body
Excircle is provided with one section of groove, groove back edge external diameter more than elastic steel wire check ring internal diameter, a sliding sleeve slide located at recessed
In groove, the rear end external diameter of sliding sleeve is less than the front end path of taper hole；
During installation, male connector body need to only be inserted the endoporus of female connector body, in the process, elastic steel wire check ring is swollen
Open, shrink be snapped between the groove rear end of male connector body and the taper hole rear end of female connector body again, play connection function, prevent two
By coming off after high pressure, the seal outside male connector body plays radial seal effect to person, can bear high pressure；During dismounting, by pusher
Sliding sleeve so as to back down elastic steel wire check ring, enter annular groove, can extract male connector body, and whole installation and unloading process are all unusual
Fast, and joint take space it is little, without using other larger instruments, less operating space is also only needed, with peace
The little advantage in dress space, with preferable applicability；On this basis, male connector body and female connector body can have larger interior
Hole, therefore flow is big, with the less pressure loss；
Used as further improvement of the utility model, seal includes O-ring seals and back-up ring；With preferable sealing
Energy.
As further improvement of the utility model, the endoporus and groove of the female connector body between closure gasket groove and annular groove
The excircle of the male connector body at rear is provided with the conical surface being engaged；Installation can be oriented to and axially position；
Used as further improvement of the utility model, the front end of sliding sleeve is provided with the radial plate of bending；Facilitate insertion into instrument, to
After promote sliding sleeve；
In sum, the utility model have that installing space is little, installing/dismounting efficiently advantage, with being preferably suitable for
Property, and flow is big, the pressure loss is little.
