Description
Technical field
The present invention relates to pipe joint, and in particular to directly-pushing connecting pipe joint.
Background technology
Pipe joint refers to the connector for connecting two segment pipes, and current most pipe joint uses screw thread or elasticity
The mode of split ring is attached.The relatively complicated complexity of these connected modes, efficiency is low.
Chinese invention patent discloses a kind of directly-pushing connecting pipe joint (Application No. 200910040489.4), and it includes connecing
Head body, is provided with bellmouth orifice in the through hole of joint body, and O-ring seal and elastic opening snap ring are provided with bellmouth orifice.Work as quilt
When connecting tube is directly pushed and plugged in the through hole of joint body, elastic opening snap ring by by wedging connected tube circumferential clasp groove
It is interior；When connected tube is extracted, elastic opening snap ring is used as a kind of locking member, it will by the osculum wedging of bellmouth orifice, and make
Connected tube can not be extracted.
It can be seen that, the effect of circumferential clasp groove is particularly important, if the depth of circumferential clasp groove is excessive, elastic opening snap ring
It will be difficult to take out by firmly wedging, or even the tube wall of connected tube is extruded into a ring impression, and cause connected tube to damage；If ring
The depth of shape snap ring groove is too small, and elastic opening snap ring is easily separated from skidding again, it is impossible to play the wedging effect to connected tube,
Connected tube is caused arbitrarily to be unpluged.
However, the tube wall of general connected tube is typically smooth surface at present, according to above-mentioned directly-pushing connecting pipe joint, then
Connected tube must be processed, to form the suitable circumferential clasp groove of depth, not only increase installation procedure, difficult processing
Degree is big, cost is high, and is also easy to block connected tube when opening up circumferential clasp groove, causes tubing to waste.
The content of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide directly-pushing connecting pipe joint, installation can be reduced
The difficulty and cost of connection, and can firm locked connected tube.
The purpose of the present invention adopts the following technical scheme that realization：
Directly-pushing connecting pipe joint, including the joint body with the through hole for being available for connected tube insertion, the end of the through hole
Provided with bellmouth orifice, the big mouth of bellmouth orifice inwardly, the osculum of bellmouth orifice outwardly, and between the osculum of bellmouth orifice and the port of through hole
Joint body wall body for sealing section, bellmouth orifice it is big it is intraoral be provided with O-ring seal, the bellmouth orifice it is small it is intraoral be provided with tight lock part
Part, the locking member includes the retainer ring and at least three balls for being used to be sleeved on connected tube, the medial extremity of retainer ring
O-ring seal is squeezed in, each ball is rolled and is installed in retainer ring, and each ball is by the inner circumferential surface and excircle of retainer ring
Protrude on surface.
On the basis of the above, the present invention can do following improvement：
Receiving hole is provided with the retainer ring, each receiving hole is distributed around the axis axial symmetry of retainer ring；Each ball rolling
It is actively tied in receiving hole.
The aperture of the receiving hole is out of retainer ring to increase outside retainer ring.
The medial extremity of the retainer ring is provided with least three bayonet sockets, and each bayonet socket is distributed around the axis axial symmetry of retainer ring.
The external peripheral surface of the retainer ring is low inside and high outside circular conical surface, and the ball protrudes from the circular conical surface.
The sealing section is separated by form unblock space along the axially extending of through hole between sealing section and connected tube.
The outboard end of the retainer ring has extension along the axially extended of retainer ring, and the unblock space is stretched into the extension
In.
The directly-pushing connecting pipe joint is also equipped with the solution lock ring for being inserted into unblock space, and the solution lock ring is empty with unblock
Gap gap coordinates.
The O-ring seal is oil sealing or section is circular or is adapted to bellmouth orifice inwall, inside and outside inner arc convex by outer arc
Arc is surrounded.
The big mouth of the bellmouth orifice is connected by a transition circle segmental arc with the wall body of joint body, and the O-ring seal is placed in
In transition circle segmental arc, the transition circle segmental arc is adapted with O-ring seal shape size and constitutes water-stop.
Compared with prior art, the beneficial effects of the present invention are：
(1) retainer ring can be supported between joint body and connected tube by ball of the invention, equivalent to ball together with
Retainer ring is rolled on same mounting surface, in the presence of retainer ring, and ball sleeve is on connected tube, and retainer ring is extruding close
The extruding elastic force that is produced after sealing rubber ring and make ball that there is the trend to outer rolling, ball and support annular relative to connected tube
Into the overall wall body gradually narrowed by bellmouth orifice extrude so that ball locks (wedging) connected tube, realize connected tube
It is firm locked.Because ball is symmetrical with the centerline axis of retainer ring, therefore ball will be produced uniformly to connected tube
Extruding force, makes connected tube uniform force, obtains good locking connection, it is to avoid connected tube is tilted, and it also avoid being connected
Pipe blocks damage by excessively locked；
(2) connected tube of the invention can be inserted directly into the through hole of joint body and realize connection, it is adaptable to outer surface
For the connected tube of smooth surface, the process for eliminating processing screw thread or groove, the difficulty and cost of connection are installed in reduction；
(3) because the aperture of receiving hole increases out of retainer ring to outside retainer ring, therefore ball can convenient loading receiving hole
In, and after being connected with connected tube, ball is locked by joint body again, therefore ball is in the assembling process with connected tube
Will not fall off, this structure can make production storage transport be more prone to, it is convenient, reliable；
(4) bayonet socket of the invention can make the resilient catch power of retainer ring generation radial direction, when retainer ring is first dragged in connected tube
When, connected tube can be held, strengthens lock ability.
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
