Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model It clearly and completely retouches, it is clear that the embodiment retouched is only the utility model a part of the embodiment, instead of all the embodiments.

Referring to Fig.1, a kind of HYP304 hand helds straight tube quick connector, including housing 18, the both ends of housing 18 open up There are opening, housing 18 to be internally provided with piston 12, the inner wall of housing 18 offers the 4th groove 17, the inside of the 4th groove 17 With the third O-ring 11 for being equipped with and being contacted with the inner wall of piston 12 piston 12 is avoided by the way that third O-ring 11 is added outside It is worn caused by when being moved in set 18.

One end of piston 12 is socketed with piston pin 15, and one end of piston pin 15 passes through 18 one end open of housing and extends to outer The outside of set 18, is socketed with inner core 13, piston 12 is located at the end surface inside piston pin 15 between piston 12 and piston pin 15 Offer multiple third grooves 14, the matching internal of third groove 14 be equipped with and contacted with 15 inner surface of piston pin second O-ring 16, third groove 14 are opened up there are three and are arranged in a manner of equidistant, by the way that multiple second O-rings 16 are arranged, are improved and are lived The leakproofness connected between plug 12 and piston pin 15, and can also prevent from skidding between piston 12 and piston pin 15, improve piston The stability of 12 installations.

The side of 12 other end of piston is equipped with the card valve 7 with 18 Matching installation of housing, and one end of card valve 7 extends to, outside The other end of set 18 extends to the inside of piston 12, is socketed with spring 10 on piston 12, the both ends of spring 10 respectively with card valve 7 and The inner wall of housing 18 connects, and the surface of card valve 7 offers the second groove 8, and the matching internal of the second groove 8 is equipped with and and housing First O-ring 21 of 18 contacts is placed and is skidded between card valve 7 and housing 18, improve card valve 7 and pacify by the way that the first O-ring 21 is added The stability of dress.

The other end opening of housing 18 is equipped with the tail-hood 6 with 18 Matching installation of housing, the one end of tail-hood 6 far from housing 18 End face offers mounting groove 20, and mounting groove 20 is internally provided with handle 1, and one end of handle 1 extends to the outside of mounting groove 20, tail Threaded pin 19 is threaded on lid 6, and one end of threaded pin 19 passes through mounting groove 20 and extends to the outer of mounting groove 20 The other end of side, handle 1 is socketed on threaded pin 19 so that handle 1 is along the surface pivots of threaded pin 19, mounting groove 20 Be internally provided with tail-hood plunger tip 5 corresponding with 1 position of handle, one end of tail-hood plunger tip 5 through tail-hood 6 and with the side of card valve 7 Contact, is equipped with connection sheet 4 between the other end and handle 1 of tail-hood plunger tip 5, the both ends of connection sheet 4 by connecting pin 22 respectively with Tail-hood plunger tip 5 and handle 1 are hinged, and the outside of housing 18, which is run through, is equipped with pipe fitting 9 corresponding with 10 position of spring, in operation handle 1 When mobile, since one end of handle 1 is limited by threaded pin 19, but handle 1 is rotated on threaded pin 19 so that handle 1 circumferentially slides, and connection sheet 4 is rotated with the rotation of handle 1 on connecting pin 22, due to one end of tail-hood plunger tip 5 It is limited by the inner wall of tail-hood 6, to push tail-hood plunger tip 5 to move in a straight line.

Operation principle：When under handle 1 being held, 5 times pressing piston pins of tail-hood plunger tip 15, piston pin 15 pushes piston 12 to move, Piston 12 squeezes card valve 7, and the contraction of spring 10 on card valve 7 makes card valve 7 open, and test specimen is put into card valve 7, handle 1, bullet are unclamped Spring 10 is moved after extending by extrusion piston 12, drive card valve 7, and test specimen is fixed after so that card valve 7 is shunk, in applied voltage test, pressure It pushes piston 12 to move to tail-hood 6, and card valve 7 is driven to be moved to tail-hood 6, make card valve 7 that the power bigger of rubber hose be clamped, when When test pressure is higher, the clamping of card valve 7 rubber hose power is bigger, and rubber hose when test is made to be not easy to deviate from.

The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
