Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Referring to Fig. 1～Fig. 5, a kind of adjustable high-voltage snap joint, including sleeve 1, joint pedestal 2, connector 3, quick
Fittings body 4, adjusting nut 5 and control stick 6.For ease of description, in specification of the present utility model, " front " refer to snap joint with
The side of pipe fitting connection, " afterwards " refers to the side that snap joint is connected with female joint.
Adjusting nut 5 is arranged on the front side of sleeve 1, is connected for the pipe joint with pipe fitting, and its periphery is formed with external screw thread
51, the leading section of sleeve 1 is formed with internal thread 11, so as to sleeve 1 may be threadably coupled to the rearward end of adjusting nut 5.Adjust
5 periphery of nut is also threaded with regulating nut 52, and regulating nut 52 can be abutted with the leading section of sleeve 1, so as to limit set
The relative position of cylinder 1 and adjusting nut 5.
Chuck 7 is provided with adjusting nut 5, chuck 7 includes at least two jaws 71,71 circumferentially-spaced arrangement combinations of jaw
The chuck 7 of ring-type is formed, by changing the gap between adjacent jaw 71, thus it is possible to vary the internal diameter of chuck 7.The inner side of jaw 71
Circumferentially extending caulking groove 711 is offered, and the combination of caulking groove 711 of each jaw 71 forms ring-type, snap ring 72 is provided with caulking groove 711,
So as to define the position of 71 circumferential inner side of jaw, that is, define the minimum diameter of chuck 7.The pipe joint insertion of pipe fitting adjusts spiral shell
Continue deeper into after in female 5 and clamped by chuck 7 so as to be inserted in chuck 7.
The lateral wall of jaw 71 is gradually radially-inwardly inclined from front to back, i.e. the rearward end external diameter of chuck 7 reaches minimum.Adjust
Hollow chuck pressure pad 8 is additionally provided with section nut 5, chuck 7 and chuck pressure pad 8 can be made of stainless steel.Chuck pressure pad 8
Madial wall shape and size be adapted to the lateral wall of chuck 7, in bowl-shape, so as to the rear portion of chuck 7 is placed in chuck pressure
The position of 71 outer circumferential of jaw in pad 8, is thus defined, that is, defines the maximum inner diameter of chuck 7, while can also cause chuck
7 gripping tube fittings.By regulating sleeve 1 and the relative position of adjusting nut 5, thus it is possible to vary chuck 7 and chuck pressure pad 8 it is relative
Position, thus changes the minimum diameter of chuck 7, to adapt to the pipe joint of different tube diameters.
In hollow cylindrical, its part is forwardly inserted in sleeve 1 joint pedestal 2, and the rear portion of joint pedestal 2 is formed with connection
Seat 21, the diameter with diameter greater than sleeve 1 of connecting seat 21 have a certain distance between the rearward end of sleeve 1 and connecting seat 21,
The distance can have regulating nut 52 to be adjusted, and the distance also just defines 2 moveable distance of joint pedestal.Thus, cover
The rearward end of cylinder 1 can with after joint pedestal 2 is moved, abut with the leading section of the connecting seat 21 of joint pedestal 2, so as to limit
Both relative displacements, namely the distance that chuck pressure pad 8 is promoted forward is defined, so as to define the journey of the clamping of chuck 7
Degree, so that adapt to the pipe fitting of different tube diameters.
The rear portion of chuck pressure pad 8 is inserted in the leading section of joint pedestal 2, and the rear side of chuck pressure pad 8 be provided with it is close
Seal, such as dimorphism sealing ring 81, are formed with radially-inwardly raised limiting section 23 on the madial wall of joint pedestal 2, sealing ring is supported
It is connected on the leading section of limiting section 23.
Connector 3 is in hollow, and its front portion is inserted in joint pedestal 2, and can be threaded connection and incite somebody to action both phases
To fixation.Snap joint body 4 is arranged on the rear side of joint pedestal 2, and the rear side of connector 3 is then inserted into 4 (public access of snap joint body
Head) in, it is also possible to it is threaded connection and both is relatively fixed.Thus when joint pedestal 2 moves linearly, 3 He of connector
4 synchronous linear of snap joint body is moved.Snap joint body 4 can be adopted for being connected with the snap joint of other pipelines (female joint)
With prior art, such as including top 41 etc..Fluid passage is formed in joint pedestal 2, connector 3 and snap joint body 4.
The rear side of limiting section 23 is provided with hollow valve element pressure pad 9, is provided with reset between valve element pressure pad 9 and connector 3
Spring 91, is provided with I-shaped shape sealing ring 92, work of the valve element pressure pad 9 in back-moving spring 91 between limiting section 23 and valve element pressure pad 9
Compressed with the lower rearward end to limiting section 23.
At least two spaced apart first installing holes 22 in the circumferential are offered on the side wall of joint pedestal 2, sleeve 1
Corresponding second installing hole 12 is offered on the wall of side.Control stick 6 include the rocking arm 61 that two tops interconnect, and two thousand
Piece 62, thousand 62 are formed as cam structure, and the top of two rocking arms 61 can be connected by connecting rod 63 so that control stick 6 is whole
Body is generally u-shaped, is provided with handle 631 in connecting rod 63, in order to operate.The bottom of each rocking arm 61 and joint pedestal 2
Rotate connection.In the present embodiment, screw 611 is locked with the first installing hole 22 through after the bottom, thousand pieces 62 one end of rocking arm 61
It is fixed, it is achieved in the connection of 61, thousand 62, rocking arm and joint pedestal 2.The other end of thousand 62 is then inserted into the by rotating shaft etc.
Realize being connected with the rotation of sleeve 1 in two installing holes 12.Thus, due to the cam structure of thousand 62 formation, when operating handle 631
During shake control stick 6,2 relative sleeve 1 of joint pedestal can be caused to move linearly in the axial direction of snap joint.
During work, by the pipe joint of pipe fitting insertion adjusting nut 5, chuck 7 is promoted to rear side, manipulation bar 6 (to
Front pressure, is pressure to the left on Fig. 3), thus, joint pedestal 2 is moved to front side straight line together with connector 3 and snap joint body 4
It is dynamic so that chuck 7 is compressed by chuck pressure pad 8；Hereafter, connect female joint, snap joint body 4 top 41 by the valve in female joint
Bar is backed down, and pipeline conducting, while back-moving spring 91 is compressed；After hours, reverse operating control stick 6, thus chuck
Pressure pad 8 leaves chuck 7, and the pipe joint of pipe fitting is no longer clamped by chuck 7, and snap joint and pipe fitting can be caused to disengage.
