Head body, joint body are provided with connecting portion, step, the connecting portion of joint body are formed between connecting portion and joint body centre
Inside inward end mouth is gradually reduced without leave, and the inside of the connecting portion is inwardly disposed with pushing block, ball fixator, ripple from port
Unrestrained packing ring, pad and sealing ring, described pushing block end are provided with the collar to turn up, and connecting portion port is provided with to internal beam mouth, collar
Coordinate with beam mouth and ball fixator, wave washer, pad and sealing ring are limited between step and beam mouth, and keep to wave
Gasket compression power；The snap joint of this structure be not suitable for the softer tube fit of quality such as metal tube, due to metal tube ratio
Softer, ball and metal tube, which coordinate, to be had metal tube local deformation and causes metal tube to move, the problems such as so as to cause poor sealing.
Utility model content
The purpose of this utility model is to provide a kind of spacing auto-locking suspension metal tube fast connecting joint, for metal
The characteristics of quality such as pipe are compared with soft pipeline, a fast connecting joint suitable for various metallic conduits is designed, in joint body
Two-port is provided with self-locking seal mechanism, needs to process a scrobicular ring at the outer wall of metal tube connection end during connection, passes through
One stainless steel retainer ring and scrobicular ring coordinate so as to ensure reliability that jointing is connected with metal tube, and the utility model has structure
Rationally, the characteristics of easy to connect.
Following technical scheme is used to achieve the above object：
A kind of spacing auto-locking suspension metal tube fast connecting joint, including joint body and metal tube, it is characterised in that：
Step is provided between the both ends and middle part of joint body, beam oral area, step and beam mouth are additionally provided with the port of joint body
Self-locking seal mechanism is provided between portion；Described self-locking seal mechanism is inwardly followed successively by lock tube, packing ring and sealing ring from port,
Described lock tube internal diameter includes three-stage structure, and the osculum internal diameter section and osculum internal diameter at port are more than the outer of metal tube
Footpath, inside are big intraoral footpath section, and centre is connected by conical section, and the position that conical section is corresponded in described lock tube is provided with card
Ring, is additionally provided with snap ring ring washer and ripple spring on the inside of snap ring, ripple spring it is front and rear respectively with snap ring ring washer and washer contacts, card
Ring ring washer is pushed up in the presence of ripple spring to snap ring, and described snap ring leaves opening, and snap ring original state external diameter is more than osculum
Internal diameter, the internal diameter of snap ring are slightly smaller than the external diameter of metal tube.
A circle scrobicular ring is offered on position of the described metal pipe outer wall close to port, when metal tube and jointing fill
With in place when, described snap ring is just connected in scrobicular ring.
Dust cover is also socketed with the end of described joint body, dust cover one end all wraps the end of joint body
Wrap up in, the other end is wrapped in metal pipe outer wall.
The utility model and existing connected mode maximum are not both to open up a circle close to the position of port in metal pipe outer wall
Scrobicular ring, snap ring is just connected at scrobicular ring after assembling in place is integrally connected with metal tube, and such metal tube moves inward meeting ripple to ripple
The outside thrust of bellows spring, and being displaced outwardly, snap ring can then be hindered by lock tube internal diameter conical section shelves metal pipe collar is obtained it is tighter,
It can not depart from all；Dust cover wraps up joint and metal duct components, plays dustproof effect while plays decoration function.
Brief description of the drawings
Fig. 1 is internal structure schematic diagram of the present utility model；
Fig. 2 is decomposition texture schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, 2, a kind of spacing auto-locking suspension metal tube fast connecting joint, including joint body 1 and metal
Pipe 2, it is characterised in that：Step 11 is provided between the both ends and middle part of joint body 1, is also set in the port of joint body 1
There is beam oral area 12, self-locking seal mechanism is provided between step 11 and beam oral area 12；Described self-locking seal mechanism from port to
Lock tube 31, packing ring 32 and sealing ring 33 are inside followed successively by, the described internal diameter of lock tube 31 includes three-stage structure, the osculum at port
Internal diameter section 311 and osculum internal diameter are more than the external diameter of metal tube 2, and inside is big intraoral footpath section 313, and centre passes through conical section 312
Linking, the position that conical section is corresponded in described lock tube 31 are provided with snap ring 34, and the inner side of snap ring 34 is additionally provided with the He of snap ring ring washer 35
Ripple spring 36, the front and rear of ripple spring 36 contact with snap ring ring washer 35 and packing ring 32 respectively, and snap ring ring washer 35 is in ripple spring
Pushed up in the presence of 36 to snap ring 34, described snap ring 34 leaves opening, and the original state external diameter of snap ring 34 is more than osculum internal diameter section 311
Internal diameter, the internal diameter of snap ring 34 is slightly smaller than the external diameter of metal tube 2.
A circle scrobicular ring 21 is offered on position of the described outer wall of metal tube 2 close to port, when metal tube 2 connects with being connected
When head is assembled in place, described snap ring 34 is just connected in scrobicular ring 21.
Dust cover 5 is also socketed with the end of described joint body, the one end of dust cover 5 is whole by the end of joint body
Parcel, the other end are wrapped on the outer wall of metal tube 2.
The utility model needs to process a circle scrobicular ring 21 on position of the metal pipe outer wall close to port, using a band
Slotted collar 34 coordinates with scrobicular ring 21, and a sound of " clatter " is heard after assembling in place, and now snap ring 34 is locked automatically with metal tube 2
Tightly, metal tube can outwards be hindered shelves by conical section 312, be depressed in metal tube 2 in normal water inwardly by the active force of ripple spring 36
Ensure the reliability that metal tube is connected with joint.
It need to only be stretched into during dismounting using specific purpose tool from gap between lock tube osculum internal diameter section and metal pipe outer wall, inwardly top
To snap ring, because snap ring leaves opening, under specific purpose tool effect, snap ring, which can be expanded, to be departed from scrobicular ring and moves inward, now
Metal tube can depart from joint easily again, and assembly or disassembly is all quite convenient.
