Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of quick connector, particularly relates to a kind of energy grafting large mouth
The quick connector in footpath.
Background technology
In daily life, producing, the pipelines such as water route, gas circuit, oil circuit are connected and usually needs to be carried out even by joint
Connect, when using traditional Pipe joint to be attached with pipeline, be essentially all by screw thread, glue, card pressure or hot melt etc.
Mode is attached, but these connected modes operate cumbersome, and it is slow again to couple together speed.Snap joint is
The problems referred to above that people exist for traditional Pipe joint and design a kind of can form connecing of being quickly connected with pipeline
Head.
Structure such as the Chinese patent once disclosed one inserted type quick coupling of conventional snap joint [application number:
201120108145.5], it includes a body in a tubular form, and the inwall of body is provided with positioning step, the port of body
Inwall is fixed with an annular dog collar with several latches, and each latch uses sheet metal to make and towards dog collar axle center side
To stretching out, being fixed with sealing ring between annular dog collar and positioning step, body is provided with a pipe for the outer end inserting plastic tube
Intubating of shape, the inner intubating is inserted in body, when connecting pipe fitting, pipe fitting is inserted into this is internal from intubating, pipe fitting
Through dog collar, the latch on dog collar can be engaged on the lateral wall of pipe fitting thus form quick connection, only need to will insert when dismounting
Dog collar is strutted and dog collar can be made to be separated with pipe fitting by pipe from outside to inside.
In above-mentioned inserted type quick coupling, spin off in joint body with intubating to prevent dog collar, typically all
The end of joint body can be arranged to reducing shape, by gradually tapering up of joint body end, dog collar and intubating be limited
Position, but snap joint when this mode is only applicable to connect small-bore pipe fitting uses.When needs connect large-caliber pipe fittings,
The internal diameter of one end that joint body connects pipe fitting certainly will need to increase according to the increase of tube outer diameter, then joint body is even
The wall thickness of one end of jointed tubular workpieces causes the end of joint body cannot come by way of inside reducing as well as thickening
Carry out spacing.
Content of the invention
The purpose of this utility model is the problems referred to above existing for prior art, it is proposed that a kind of quick connector,
Solve the technical problem that the applicability being how to improve quick connector, especially when grafting large-caliber pipe fittings more easily to inserting
Access node structure positions.
The purpose of this utility model can be realized by following technical proposal:
Quick connector, including joint body, one end of described joint body is inserted terminal, is provided with in described inserted terminal
Collar and internal lining pipe, it is characterised in that be additionally provided with in circular centring ring in described inserted terminal, outside described centring ring
Sidewall leans with the madial wall of inserted terminal, and described centring ring is limited in collar and internal lining pipe in inserted terminal, and described inserts
Connecing and being bolted with locking cap outside end, the inner side of described locking cap is resisted against on the rear end of centring ring, after described internal lining pipe
End sequentially passes through centring ring and locking cap and is positioned at outside locking cap.
Quick connector assembling when, be placed on collar and internal lining pipe in inserted terminal, then will in the form of a ring and external diameter with insert
Connecing the corresponding centring ring of the internal diameter of end and putting in inserted terminal, it is spacing in inserted terminal, that collar and internal lining pipe are positioned circle
After be spirally connected outside inserted terminal locking cap, after locking cap connects, the inner side of locking cap and the rear end of centring ring form against making
Centring ring forms positioning, just directly positions collar and internal lining pipe thus, and this mode makes collar and liner
The positioning of pipe becomes simpler, and when especially this quick connector being used for grafting large-caliber pipe fittings, this positioning mode more can
Solve the orientation problem of big specification collar and internal lining pipe well, improve the applicability of quick connector well.
Quick connector
In above-mentioned quick connector, the front end outer side of described internal lining pipe has annular convex shoulder, described centring ring in
Annular, the rear inside of described centring ring has convex annular edge, and described annular convex shoulder leans with convex annular edge.
The rear end of internal lining pipe passes through from centring ring, the annular convex shoulder of the front end outer side of internal lining pipe and centring ring rear inside
Annular gear along formed against, then centring ring just can be by spacing for internal lining pipe in the inserted terminal of joint body.
In above-mentioned quick connector, having ring-shaped step in described inserted terminal, the outer of described collar is resisted against
On ring-shaped step, the front end of described centring ring is pressed on the outer of collar.
It during installation, is first placed on collar on the ring-shaped step in inserted terminal, then the annular convex shoulder by internal lining pipe front end
With the convex annular of centring ring rear end along after leaning, internal lining pipe and centring ring are together put into inserted terminal, at centring ring by interior
Bushing pipe spacing in inserted terminal while, the front end of centring ring is pressed on the outer of collar and has also carried out spacing to collar simultaneously.
In above-mentioned quick connector, described inserted terminal is enlarging shape relative to joint body, described inserted terminal
Back segment is threaded section, and the external diameter of described threaded section is less than the external diameter of the leading portion of inserted terminal.
Owing to the inserted terminal of this quick connector is for grafting large-caliber pipe fittings, then in order to enable large-caliber pipe fittings
Being plugged in inserted terminal, the internal diameter of inserted terminal needs sufficiently large, thus causes the external diameter of inserted terminal also relatively large, by inserted terminal
Back segment be set to less threaded section of external diameter, primarily to avoid causing locking cap because the external diameter of inserted terminal is excessive
Oversize.
In above-mentioned quick connector, the rear end face of described locking cap is evenly distributed some connecting holes.
When mounted, instrument is connected with the connecting hole on locking cap outer face, then drives lock by turning tool
Tight cap rotates the inserted terminal bolt making locking cap and joint body.
Compared with prior art, this quick connector is by arranging centring ring in inserted terminal, utilize centring ring by collar and
Internal lining pipe is spacing in inserted terminal, and forms centring ring spacing by the locking cap that is spirally connected in the port of inserted terminal, thus
Form positioning easily to collar and internal lining pipe, especially when this quick connector is used for grafting large-caliber pipe fittings, this fixed
Position mode can solve the orientation problem of big specification collar and internal lining pipe well, improves being suitable for of this quick connector well
Property.
