Embodiment
As Figure 1-4, universal jack catchs type connector comprises:
At least two claws 2, described claw 2 surround one with in the catch jacket of logical endoporus, catch jacket is divided into flared end and connecting end, its flared end can be blocked pipe fitting 1 one end after tightening up.(as shown in Figure 4) in the present embodiment, claw 2 has three compositions, forms 360 degree angular ranges.Can be firmly when pipe fitting 1 the is clamped tight pipe fitting 1 that blocks.
In order to guarantee precision and the conformity of the catch jacket that three claws 2 form, at processing link, by lathe one, process the semi-finished product blank of a whole claw 2, re-use the modes such as line cutting its equal angles is cut into three impartial parts.Such processing mode assurance work efficiency that both saved time, conformity and the precision of assurance processing that again can be best.Adopting three claws 2 is a kind of scheme in the present embodiment, also can adopt claw 2 combinations that are no less than two.
In the utility model, the catch jacket that claw 2 forms can clamp pipe fitting 1 type of carrying out quick links and mainly include flanged pipe, fish scale pipe, and hot-expanding pipe, enlarging, short end is first-class.Be illustrated in figure 1 common pipe fitting sectional drawing.Its common feature is the boss with at least one, can use claw to block this boss, and in figure, fitting surface II 16 is the surface of contact of claw 2 and pipe fitting 1 boss rear side.The projection of boss and claw 2 block the position limitation that guarantees clamping
Overcoat 5 and rear connecting base 9 within it of socket, have through hole in described rear connecting base 9, and under elastic element effect with the axial relative sliding of described overcoat 5, the connecting end of described catch jacket is set in its gap, rear connecting base 9 can drive slip before and after catch jacket.The elastic force providing while being subject to elastic element (spring III 10) pre-pressing state due to overcoat 5, so can keep certain tightness between overcoat 5 and rear connecting base 9, intermediate gaps place is for installing the connecting end of catch jacket.During installation, claw 2 is inserted in this space one by one, overcoat 5 is subject to clamp all claws 2 with rear connecting base 9 actings in conjunction after the elastic force resilience of elastic element (spring III 10).(see figure 2)
Described piston 4, is hollow tubular, and concentric is located in the through hole of rear connecting base 9;
Described piston 4 its outsides, one end are provided with the fitting surface I 15 offseting with catch jacket inner side surface, do not prop up catch jacket inner side during connection pipe fitting 1 it is opened.
Its other end is provided with elastic element (spring I 6), can make piston 4 be tight against pipe fitting 1 and slide front and back in the axial direction with it during connection pipe fitting 1.In the present embodiment, as shown in Fig. 1 or 2, spring I 6 is arranged between piston 4 and rear connecting base 9, and the pre-pressing force by spring I 6 makes pipe fitting 1 prop up the forward end seal circle 3 on piston 4, makes it produce elastic strain, reaches seal action.
The diameter of bore of described piston 4 matches with described pipe fitting 1 interior conduit diameter, and after clamping pipe fitting 1, source of the gas etc. enter pipe fitting 1 by piston 4.The object designing because of this model utility is in order to connect and to seal and set up fluid passage fast, so the piping design object in piston 4 is exactly the path for providing gas or liquid to pass through.
Described overcoat 5, one end is provided with the fitting surface III 17 offseting with catch jacket outer side surface, and catch jacket tightens up and blocks after pipe fitting 1, and overcoat 5 props up catch jacket and stops it to open.In this embodiment, as shown in Figure 3, be additionally provided with the fixed platform that provides the elastic element of spring-back force to install for offering overcoat 5, spring catch ring 11.The elastic element (spring III 10) of installing on spring catch ring 11, for overcoat 5 provides one to the elastic force F of catch jacket direction, tightens up catch jacket and blocks after pipe fitting 1, and overcoat 5 offsets with the fitting surface III 17 that catch jacket outer side surface offsets.Realize the locking link after catch jacket clamping pipe fitting 1.If now do not apply external force, do not push overcoat 5 open, catch jacket can clamp pipe fitting 1 all the time.
Gap shape between described overcoat 5 and socket rear connecting base 9 within it cooperatively interacts with the shape of described catch jacket connecting end.Preferably fit shapes both can guarantee claw 2 existing certain activity space in gap, can guarantee that again claw 2 can not deviate from gap.Spring II 8 is arranged in gap can better keep the tightness of claw 2 in gap.
Described catch jacket connecting end is provided with groove, and described rear connecting base 9 is provided with the projection matching with it, and rear connecting base 9 drives catch jacket with sliding before and after it when slide in axis front and back.
Described spring catch ring 11, is arranged at one end that rear connecting base 9 is not established catch jacket, and 5, described spring catch ring 11 and overcoat are provided with elastic element (spring III 10), and elastic element makes the thrust of oriented fitting surface III 17 motions of overcoat 5.In this embodiment, be provided with jump ring 12 in order to limit the position of spring catch ring 11.
Described spring catch ring 11 is socketed in overcoat 5, between itself and overcoat 5, is provided with elastic element, and during connection pipe fitting 1, elastic element promotes overcoat 5 and the fitting surface III 17 between overcoat 5 and catch jacket is tight against, and claw 2 can not unclamp pipe fitting 1.
Described spring catch ring 11 is affixed by jump ring 12 and rear connecting base 9.
In rear connecting base 9, be provided with pipeline, source of the gas etc. pass through its pipeline, piston 4 until in pipe fitting 1.
Also comprise forward end seal circle 3 and back-end sealing circle 7, divide and be located between piston 4 and pipe fitting 1 surface of contact and rear connecting base 9 and piston 4 surface of contact.The object that it is set be avoid gas or liquid pass through the pipeline of this model utility inside time there is seepage, affect using effect.
The using process of this model utility:
Standby condition:
As shown in Figure 2, connector is in not-connected status, and catch jacket opens, and 5 pairs of catch jackets of overcoat are without constraint, and spring III 10 is in compressive state.Because of the restriction of fitting surface I 15, spring I 6 compressive states prop up piston 4, make front end piston 4 fitting surface I 15 positions in Fig. 2.
Connect clamping:
Hold overcoat 5, piston 4 perpendicular alignmnet connecting tubes 1, promote forward the overcoat 5 of this universal claw, and piston 4 moves right under the pipe fitting 1 being connected promotes, catch jacket clamping pipe fitting 1.Now, overcoat 5 is moved to the left under the 10 restoring force effects of spring III, until catch jacket is limited by fitting surface III 17.
Clamping discharges:
Pull overcoat 5 to the right, catch jacket departs from the restriction of fitting surface III 17, and piston 4 is moved to the left under the restoring force effect of spring I 6, and each claw 2 promoting in catch jacket outwards opens, and pipe fitting 1 is discharged.Connector is returned to standby condition, waits pending connection fast next time.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
