Description
Technical field
The present invention relates to recanalization technical field, more particularly to a kind of metal latch immediately pipe device.
Background technology
In existing pipeline plugs into field, card convex type connection is most commonly seen attachment device.Card convex type connection is convex
Ring rectangular triangle or arc-shaped, sealing ring use end face seal mode, have a conical seal ring at screw thread, by screw thread
To the connection type of the crush seal of conical seal ring.Its Connection Step includes：1. tube length needed for in-site measurement simultaneously carries out
Interception；2. expanding bulge loop to the pipe of interception with special expansion bulge loop machine, pipe should be inserted into the upper roll wheel end of bulge loop machine when expanding bulge loop
Inner plane is close in face, and makes tube axis parallel with roller axis；3. being changed hands to tube wall by expanding the compression on bulge loop machine
Slowly pressurization, gradually protuberance one encloses bulge loop to pipe outward；4. expanding bulge loop machine has been provided with bulge loop limit height and width, bulge loop is confirmed
Compression is unscrewed after being of the required size to change hands, and pipe is exited from expanding on bulge loop machine upper roll wheel.
It is larger due to expanding bulge loop body product, and price is relatively high, therefore only sole duty carries out applying for pipeline connection engineering
Crew can just purchase.And general user expands bulge loop machine due to lacking, so card convex type can not be used to connect pipeline of voluntarily plugging into.
Invention content
Place to solve the deficiencies in the prior art, the present invention provides a kind of metal latch immediately pipe devices, use and block
The close principle of male connection goes to realize the sealing and locking of recanalization, but expands bulge loop machine to pipe without relying on again simultaneously
Processing so that general user also can voluntarily complete recanalization.
A kind of metal latch immediately pipe device, including wait for connecting tube, left connector, right connector and lock ring, the left company
Fitting and right connector are socketed with connecting tube is waited for, and to be threadedly coupled between left connector and right connector, the lock ring
For standard revolving body, section includes bottom edge, top margin, left contact edge and right contact edge, the lock ring formed by the bottom edge
Inner wall is adapted with the outer wall of connecting tube is waited for, the top margin is abutted with the inner wall of left connector or right connector, the left contact
Side and/or right contact edge form acute angle α with bottom edge, and the left connector has left compressing end face, the left compressing end face
The surface formed with the left contact edge in lock ring section is interference fitted, and the right connector has right compressing end face, the right pressure
Compel end face and the surface of the right contact edge formation in lock ring section is interference fitted.
Further, the left compressing end face and/or right compressing end face form acute angle β, the angle β with connecting tube is waited for
More than angle α.
Or the inner wall of the lock ring is equipped with groove.
Further, sealing ring is equipped in the groove.
When the inner wall of lock ring is equipped with groove, the left compressing end face and right compressing end face are vertical with connecting tube is waited for.
Further, the sealing ring is one kind in Teflon member, EPDM component or silica gel component.
Immediately pipe device is machined to enable without expanding bulge loop metal latch disclosed by the invention by adding lock ring
Wait for connecting tube also and can be formed be similar to bulge loop used in card convex type connection.Simultaneously because at least side on lock ring
It is wedge structure, therefore it can be due to being interference fitted during left connector and right connector are threadedly coupled locking
And deform upon, and then insertion waits for connecting tube, can play good sealing effect.

The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and attached drawing clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, the embodiment of the present invention, those skilled in the art are not paying creation
Property labour under the premise of the other embodiment that is obtained, belong to the scope of protection of the invention.In addition, what is be previously mentioned in text is all
Connection/connection relation not singly refers to component and directly connects, and referring to can be according to specific implementation situation, by adding or reducing connection
Auxiliary is connect, to form more preferably coupling structure.Each technical characteristic in the invention, in the premise of not conflicting conflict
Under can be with combination of interactions.
Embodiment 1：As illustrated in fig. 1 and 2, a kind of metal latch immediately pipe device, including wait for connecting tube 1, left connector 2-1,
Right connector 3-1 and lock ring 4-1, the left connector 2-1 and right connector 3-1 are socketed with connecting tube 1 is waited for, and left connection
To be threadedly coupled between part 2-1 and right connector 3-1, the lock ring 4-1 is standard revolving body, and section includes bottom edge, top
Side, left contact edge and right contact edge, the inner wall of the lock ring 4-1 formed by the bottom edge are adapted with the outer wall of connecting tube 1 is waited for,
The top margin is abutted with the inner wall of left connector 2-1, and the left contact edge and right contact edge are respectively formed acute angle α with bottom edge,
The left connector 2-1 has left compressing end face, the table of the left compressing end face and the left contact edge formation in the sections lock ring 4-1
Face is interference fitted, and there is the right connector 3-1 right compressing end face, the right side of right the compressing end face and the sections lock ring 4-1 to connect
The surface interference fit that side is formed is touched, the left compressing end face and right compressing end face form acute angle β, institute with connecting tube 1 is waited for
It states angle β and is more than angle α.
When implementing recanalization, first lock ring 4-1 sets are connected to and waits in connecting tube 1 and is located at the left right connections of connector 2-1
Between part 3-1, it is then connected through a screw thread the left connector 2-1 and right connector 3-1 of tightening, since angle β is more than angle α, is made
It obtains left compressing end face and right compressing end face to be interference fitted with the both sides lock ring 4-1, since the both sides lock ring 4-1 are wedge-shaped knot
Structure deforms upon under the compressing of left and right compressing end face, the tube wall for waiting for connecting tube 1 is partially submerged into, to realize pipe connecting device
Waterproof sealing.
Embodiment 2：As shown in Figures 3 and 4, a kind of metal latch immediately pipe device, including wait for connecting tube 1, left connector 2-2,
