Description
Technical field
The utility model relates to a kind of fast joint chair.
Background technique
At present, the general employing that be connected of flexible pipe and water flowing member is spirally connected or the mode of clamping, need twine the sealing adhesive plaster in the tooth place being spirally connected outside when being spirally connected, to the control of alignment error difficulty; Need use said quick-acting joint during clamping, existing quick-acting joint mainly comprises post seal washer and the protruding locating piece of card, has defective generally, easily slides as wherein post seal washer, blocks radially amplitude of oscillation considerable influence sealability etc. of protruding locating piece.
The model utility content
Technical problem to be solved in the utility model provides a kind of to flexible pipe good seal performance, installation and all more convenient fast joint chair of dismounting.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of fast joint chair, comprise the water flowing member, the water flowing member is provided with the bellmouth of the flexible pipe that is used to peg graft, the described bellmouth outside is provided with the location substrate more than, bellmouth and location are provided with the post seal washer between the substrate, and the location substrate is provided with and protrudes from location substrate inwall to be used for fixing the location card of flexible pipe protruding; Described location substrate has screw thread near the outer wall and the bellmouth outer wall of the terminal ring body of bellmouth, location substrate, the screw-casing that bellmouth is provided with outward to removably connect with its formation screw thread; Screw-casing, location substrate are equipped with and are used for the hollow structure that flexible pipe passes.
Post seal washer of the present utility model is fastening by packing ring in the annular space that bellmouth and location substrate constitute, flexible pipe insert or dismounting is extracted and during in the water flowing pressure-bearing post seal washer can not produce displacement, guaranteed the sealing of post seal washer to flexible pipe; Simultaneously, it is protruding that location substrate inwall is provided with the location card that is used for fixing flexible pipe, and this location card is protruding to be rabbeted with the flexible pipe outer wall, prevents from outwards to skid off after flexible pipe from inserting bellmouth.
Be provided with packing ring between described location substrate and the post seal washer, the internal diameter of described packing ring is less than the internal diameter of the hollow structure of location substrate formation.Generally, have bigger gap between the flexible pipe outer wall that inserts bellmouth and the location substrate, it is bigger that its end and post seal washer contact annular space, has influence on the sealing stability and the sealability of post seal washer; Therefore be provided with packing ring between location substrate and post seal washer, the matching degree of its internal diameter and hose outside diameter is higher, can make the sealing effect of post seal washer more effective.
The protruding end that is positioned at the location substrate away from bellmouth of described location card.
Described location substrate outer wall thickness increases to nearly bellmouth one end of location substrate gradually from containing the protruding end of location card, forms the close-fitting inclined-plane, and described screw-casing inwall is provided with the inner pressure ring face that contacts with the close-fitting inclined-plane.This structure is convenient to the Assembly And Disassembly of flexible pipe.During assembling, only need earlier flexible pipe to be inserted in the bellmouth, again screw-casing is screwed: in the process that screw-casing screws, the inner pressure ring face is along with screw-casing moves to the direction near bellmouth, because close-fitting inclined-plane outer wall thickness increases gradually, locate substrate and be provided with the protruding end of location card and inwardly tighten this moment, makes that location card is protruding to compress interlocking with flexible pipe, can prevent that flexible pipe from outwards skidding off when pressure-bearing; During dismounting, only need screw-casing is outwarded winding, in the process that screw-casing is outwarded winding, the inner pressure ring face is along with screw-casing moves to the direction away from bellmouth, because close-fitting inclined-plane outer wall thickness reduces gradually, locate substrate and be provided with the protruding end of location card and outwards open this moment, make location card protruding with flexible pipe away from, extract flexible pipe and get final product this moment; Location card is protruding to open amplitude hour running into, as long as radially wobble flexible pipe, just can extract flexible pipe smoothly.
Described bellmouth end has that to prevent to locate substrate be the limit structure of axle rotation with the flexible pipe with screw-casing.
Described limit structure comprises the locating column that protrudes from the bellmouth end of at least one, and locating column has projection or groove with the inwall that the location substrate contacts, and the location substrate has groove or the projection that is complementary with it in projection or groove position contacting with locating column.
Described limit structure comprises on the bellmouth end face projection or the groove of at least one, and the relative position of substrate bottom surface, location and bellmouth has groove or the projection that is complementary.
To sum up, the beneficial effects of the utility model are: the annular space build-in that post seal washer of the present utility model is made of bellmouth and location substrate, flexible pipe insert or dismounting is extracted and during in the water flowing pressure-bearing post seal washer can not produce displacement, guaranteed the sealing of post seal washer to flexible pipe; Simultaneously, it is protruding that location substrate inwall is provided with the location card that is used for fixing flexible pipe, and this location card is protruding to be rabbeted with the flexible pipe outer wall, prevents from outwards to skid off after flexible pipe from inserting bellmouth.The location substrate of this programme can be a flexible pipe position structure with cylindrical hollow configuration, perhaps constitutes a flexible pipe position structure with cylindrical hollow configuration by several component compositions.
