The present invention has the advantages and positive effects of:Due to using above-mentioned technical proposal so that this is quick
Joint is achieved a butt joint fastening using the principle of handle extruding, when by handle by horizontal pressing being plumbness,
Realize that the extruding that tapered sleeve is fixed to front end tapered sleeve and rear end fastens using the rebound effect of spring, and then utilize
Front end tapered sleeve and rear end fix tapered sleeve realize to fixing card valve outwardly against, and then realize snap joint with
The docking of steel pipe, realizes the rapid abutting joint of snap joint, and by fixing card valve be arranged on inner core connecting rod and
Among test specimen steel pipe, the fastness of snap joint can be greatly improved, avoids the slippage of snap joint.
The course of work of this example:
As shown in figure 1, handle 1 is in horizontality with movable inner core 3, now movable inner core 3 is in handle
Spring 5 will be extruded under the pressure of hand 1, now spring 5 is in compressive state, in movable inner core
3 will promote inner core connecting rod 11 to be moved to the direction away from shell 6 when being in compressive state, because inner core connects
Bar 11 is displaced outwardly so that front end tapered sleeve 13, rear end are fixed between tapered sleeve 8 and fixing card valve 9 in certainly
Right relaxation state, in the presence of polyurethane O-ring 10, make fixing card valve 9 to contract, now soon
Quick coupling is in open mode.
As shown in Fig. 2 press down on handle 1, when making it with movable inner core 3 be in 90 ° of angles, due to
Handle 1 is pressed the Distance Shortened with movable inner core 3 afterwards, in turn results in movable inner core 3 in spring 5
Moved under effect to the direction of handle 1, due to movable inner core 3 motion so that drive inner core connecting rod 11 to
The direction of shell 6 is moved, and the motion of inner core connecting rod 11 will extrude rear end and fix tapered sleeve 8 and front end tapered sleeve 13
Relative motion is realized, the end contacted due to rear end fixation tapered sleeve 8 and front end tapered sleeve 13 with fixing card valve 9
Face is inclined design, will realization pair when tapered sleeve 8 is fixed in rear end and front end tapered sleeve 13 carries out relative motion
Fixing card valve 9 outwardly against and then the fixation of snap joint and target steel pipe being realized, due to fixing card
Valve 9 is arranged between inner core connecting rod 11 and shell 6, is fixing card using inner core connecting rod 11 and shell 6
Valve 9 provide support force, it is possible to increase the stability of snap joint, and for pressure in steel pipe it is larger when,
Due in steel pipe during pressure it is outside, pressure will promote inner core connecting rod 11 to be moved to the direction of shell 6,
Inner core connecting rod 11 will be extruded further fixing card valve 9 during moving, and realize fixing card valve 9
Further fastening, so as to effectively avoid snap joint and steel pipe from slipping the appearance of situation, change significantly
It has been apt to common snap joint and has born the shortcomings that pressure is small low with service life.
Embodiments of the invention are described in detail above, but the content is only the preferable of the present invention
Embodiment, it is impossible to be considered as the practical range for limiting the present invention.It is all to be made according to the present patent application scope
Equivalent change with improve etc., all should still belong to the present invention patent covering scope within.
