Description
Technical field
The present invention relates to quick coupling, specifically a kind of limiting auto-locking suspension metal tube fast connecting joint.
Background technology
Notification number is：CN204756246U discloses a kind of fast connecting joint of pipeline, is made and connects including metal material
Head ontology, joint body are equipped 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, wave from port
Unrestrained washer, gasket and sealing ring, the pushing block end are equipped with the retainer ring to turn up, and connecting portion port is equipped with to internal beam mouth, retainer ring
Coordinate with beam mouth and ball fixator, wave washer, gasket and sealing ring are limited between step and beam mouth, and keep to wave
Gasket compression power；The quick coupling of this structure be not suitable for the softer tube fit of quality such as metal tube, due to metal tube ratio
Softer, there are metal tube local deformations that metal tube to be caused to move for the cooperation of ball and metal tube, the problems such as so as to cause poor sealing.
Invention content
The purpose of the present invention is to provide a kind of limiting auto-locking suspension metal tube fast connecting joint, for metal tube etc.
The characteristics of quality is compared with soft pipeline designs a fast connecting joint suitable for various metallic conduits, at the both ends of joint body
Mouth is provided with self-locking seal mechanism, and when connection needs to process a concave ring at the outer wall of metal tube connecting pin, by one not
Rust steel snap ring and concave ring coordinate to ensure reliability that jointing connect with metal tube, of the invention with rational in infrastructure, connect
Connect the characteristics of facilitating.
Following technical scheme is used to achieve the above object：
A kind of limiting auto-locking suspension metal tube fast connecting joint, including joint body and metal tube, it is characterised in that：Connector
Be provided with step between the both ends and middle part of ontology, be additionally provided with beam oral area in the port of joint body, step and beam oral area it
Between be provided with self-locking seal mechanism；The self-locking seal mechanism is inwardly followed successively by lock tube, washer and sealing ring from port, described
Lock tube internal diameter include three-stage structure, the outer diameter of metal tube is more than by the osculum internal diameter section at proximal port and osculum internal diameter, it is interior
Portion is big mouth internal diameter section, and centre is connected by conical section, and the position that conical section is corresponded in the lock tube is equipped with snap ring, snap ring
Inside is additionally provided with snap ring ring washer and ripple spring, ripple spring it is front and rear respectively with snap ring ring washer and washer contacts, snap ring ring washer
It is pushed up under the action of ripple spring to snap ring, for the snap ring there are opening, snap ring original state outer diameter is more than osculum internal diameter, card
The internal diameter of ring is slightly smaller than the outer diameter of metal tube.
A circle concave ring is offered on position of the metal pipe outer wall close to port, when metal tube and jointing fill
With in place when, the snap ring is just connected in concave ring.
Dust cover is also socketed in the end of the joint body, dust cover one end all wraps the end of joint body
It wraps up in, the other end is wrapped in metal pipe outer wall.
Of the invention and existing connection mode maximum is not both that a circle concave ring is opened up in the position of metal pipe outer wall close to port,
Snap ring is just connected at concave ring after assembling in place is integrally connected with metal tube, and such metal tube moves inward meeting wave to ripple spring
Outside thrust, and be displaced outwardly, snap ring then can be hindered shelves by lock tube internal diameter conical section and metal pipe collar is obtained to tighter, basic nothing
Method is detached from；Dust cover wraps up connector and metal duct components, plays dustproof effect and plays decoration function simultaneously.
Description of the drawings
Fig. 1 is the internal structure schematic diagram of the present invention；
Fig. 2 is the decomposition texture schematic diagram of the present invention.
Specific embodiment
As shown in Figure 1, 2, a kind of limiting 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；The self-locking seal mechanism from port to
Lock tube 31, washer 32 and sealing ring 33 are inside followed successively by, 31 internal diameter of lock tube includes three-stage structure, by the osculum at proximal port
Internal diameter section 311 and osculum internal diameter are more than the outer diameter of metal tube 2, and inside is big mouth internal diameter section 313, and centre passes through conical section 312
Linking, the position that conical section is corresponded in the lock tube 31 are equipped with snap ring 34, and 34 inside of snap ring is additionally provided with 35 He of snap ring ring washer
Ripple spring 36, the front and rear of ripple spring 36 contact respectively with snap ring ring washer 35 and washer 32, and snap ring ring washer 35 is in ripple spring
It is pushed up under the action of 36 to snap ring 34, there are openings for the snap ring 34, and 34 original state outer diameter of snap ring is more than osculum internal diameter section 311
Internal diameter, the internal diameter of snap ring 34 is slightly smaller than the outer diameter of metal tube 2.
A circle concave ring 21 is offered on position of 2 outer wall of metal tube close to port, when metal tube 2 connects with connecting
When head is assembled in place, the snap ring 34 is just connected in concave ring 21.
Dust cover 5 is also socketed in the end of the joint body, 5 one end of dust cover is whole by the end of joint body
Package, the other end are wrapped on 2 outer wall of metal tube.
The present invention needs to process a circle concave ring 21 on position of the metal pipe outer wall close to port, is open using a band
Snap ring 34 coordinates with concave ring 21, and a sound of " clatter " is heard after assembling in place, at this time snap ring 34 and 2 auto lock of metal tube,
Metal tube inwardly by 36 active force of ripple spring, shelves can be hindered by conical section 312, are depressed in metal tube 2 in normal water true outward
Protect the reliability that metal tube is connect with connector.
It need to only be stretched into from gap between lock tube osculum internal diameter section and metal pipe outer wall using specific purpose tool during dismounting, inwardly pushed up
To snap ring, due to snap ring, there are openings, and under specific purpose tool effect, snap ring, which can be expanded, to be detached from concave ring and move inward, at this time
Metal tube can be detached from connector easily again, and assembly or disassembly is all quite convenient.
