Description
Technical field
The present invention relates to field of mechanical technique, more specifically, particularly to a kind of locking type snap joint.
Background technology
In daily life, the transmission of fluid is required to carry out by tubing.And in whole tubing, due to
Limited by length, be all to be made up of many segment pipes, the connection between many segment pipes is needed to carry out by pipe fittings such as joints.For
Reach the convenient purpose of Pipe installing, people devise various snap joints.The structure of existing snap joint is mostly by joint
Body, and be arranged on the inwardly angled pawl piece of intrinsic distribution annular in shape and be located at joint body oral area one in pawl piece
The set that unloads of side setting is constituted.When installing water pipe, water pipe inserts joint, and pipe outer wall is pushed pawl piece and opened, pawl piece after putting in place
Block pipe outer wall, be allowed to extract, reach the purpose of quick links.To extract water pipe, then caliber is utilized to be more than water pipe
Unload set extruding pawl piece, be allowed to lose clamping force, thus water pipe is extracted.But this snap joint there is also defect.Fall
Gear piece is only capable of blocking the tubing made by the relatively low material of hardness, and as high tubing in the hardness such as rustless steel, copper pipe then can not reliably connect
Connect, and pawl piece easily scratches water tube surfaces, affect sealing.
In order to improve the connectivity robustness of tubing and joint, traditional method is by fitting end periphery axial lock positioning
The technique putting processing ring groove, when in tubing insertion joint, profile of tooth collar is cut groove to improve the fastness of connection.Its
Bellmouth by bushing, collar, back cushion, O-ring, unload set etc. and form, complex structure, manufacturing process has high demands.Although it is applied widely,
But connection reliability is poor.
Content of the invention
It is contemplated that at least solving one of problem present in background technology.
An object of the present invention is to provide a kind of locking type snap joint, quickly and stable using described snap joint
Realize described snap joint and adapter between connection.
For reaching above-mentioned purpose, the present invention provides a kind of locking type snap joint, and it includes being arranged on described snap joint
The first interior potted component and elastic device, also include be arranged between described first potted component and described elastic device
Two potted components.
It is connected with elastic device by installing the second potted component additional, be connected between the described snap joint of raising and adapter
Reliability, simultaneously so that the first potted component is not affected by other parts, greatly provides the sealing effect of described snap joint
Really.
Further, described first potted component and described second potted component can be sealing ring.
Further, described elastic device can be butterfly spring or helical spring, can also be annular elastomeric
Spring.
Preferably, described elastic device is wavy spring.
Further, it also includes being arranged on the bushing being connected in described snap joint and with described second potted component,
It is provided with holding set, described holding puts and is provided with locking member in described bushing；Described elastic device is arranged in described bushing
And keep set to be connected with described.
Reliability and the intensity that tubing is connected with described snap joint can be strengthened using described bushing.
By connecting described holding set and described second potted component using elastic device, described snap joint is with tubing even
Connect and water flowing, the described holding set shift in position being led to because hydraulic pressure changes using described elastic device available buffer, thus slow down pipe
Motion between material and described snap joint, improves the stability of connection and described snap joint carries hydraulic pressure ability, simultaneously
Also improve the sealing effectiveness of described snap joint.
Further, the section of described locking member is circle.
Described locking member can be spherical balls or the rigidity of American football shape steel ball or other materials
Ball.
When the section of described locking member is circular, described locking member, tubing are more easy to lock with the inwall of described snap joint.
Further, described bushing is gradually reduced toward its internal diameter of one end of the described snap joint mouth of pipe.
When tubing accesses to described snap joint, described tubing is contacted with described locking member, by locking member to described lining
Set inwall moves, and when tubing will exit described snap joint, tubing and described locking member move to the described snap joint mouth of pipe,
But described bushing is gradually reduced toward its internal diameter of one end of the described snap joint mouth of pipe, described locking member and tubing contact point are to locking
When the distance between part and described bushing contact internal walls point are more than described bushing inner diameter with interface external diameter sum, tubing and described lining
Cover locking, when tubing exits described snap joint further, lock wire can produce naturally, and described snap joint is more next with tubing
Tighter.
Further, described its external diameter of one end keeping the past described snap joint mouth of pipe of set is gradually reduced.
Its internal diameter of described holding set one end is gradually reduced, and facilitates the described relative motion keeping set and described bushing.
Further, described snap joint outer wall is provided with the first convex shoulder and the second convex shoulder, and described snap joint inwall sets
It is equipped with the first flanged structure being connected with described first potted component and the second flange being connected with described second potted component
Structure.
The id tolerance that described first potted component is located at described snap joint inwall with described second potted component
Control so that described first potted component and described second potted component form certain compression ratio, when tubing insertion is described fast
During quick coupling, under the protection of joint, tubing is unlikely to deform, and outside is tight with the first potted component and the second potted component
Contact, forms wider seal line, this provides Reliable guarantee for sealing；It is close that described second flanged structure blocks described second
Envelope element, described second potted component blocks described elastic device, described elastic device prop up described keep set so that
The more stable locking adapter of described snap joint.
Further, it also includes unloading set, and described one end unloading set is arranged between described bushing and described holding set, separately
The mouth of pipe of described snap joint is extended in one end.
When tubing is exited described snap joint, the described set that unloads is pushed away to described bush inside, promotes described holding
Cover and move to the inside of described snap joint, described locking member is no longer influenced by the extruding of tubing and described bushing inwall, at this moment can move back
Go out tubing.
Further, described snap joint inwall is additionally provided with third lip structure.
Described third lip structure is used for stoping tubing from going successively to described snap joint.
The beneficial effects of the present invention is, provide a kind of locking type snap joint, this snap joint is close by installing second additional
Envelope element is connected with elastic device, improves the reliability being connected between described snap joint and adapter, simultaneously so that first is close
Envelope element is not affected by other parts, greatly provides the sealing effectiveness of described snap joint.
