Abstract
The utility model provides the technical proposal of a quick joint for a hose. The technical proposal mainly comprises a socket joint, a supported joint and a thread press cover, wherein, a locking cover sheathed on a supported port of the supported joint is provided with a locking ring; an outer ring of the locking ring is contacted with the inner conical surface of the supported port of the supported joint; the locking ring is provided with a disconnection seam; an annular sealing groove is arranged in the supported port of the supported joint; a sealing ring is arranged in the sealing groove; an annular groove is arranged on the outer surface of a socket of the socket joint; when the supported joint and the socket joint are socketed and connected, the inner ring of the locking ring is embedded in the annular groove. The utility model has the advantages of novel and simple structure, quick joint, convenient operation and low cost; the utility model can be made of plastic and is suitable for the connection of various fluid transfer hoses.
Description
The utility model relates to a kind of quick type coupling head, especially a kind of gladhand.
In the prior art, it is insecure to be used for the connection that the socket joint connecting joint of flexible pipe has, the rapid pipe joint locking mechanism complexity that has, and most metallic material that uses is made the fabricating cost height.
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of technological scheme of gladhand is provided.Locking mechanism is simple, socket joint connects firmly, tight, connect quick, easy to use.
The purpose of this utility model is achieved in that the described gladhand of this scheme, mainly comprises connection-peg, accepts head and union (screwed)bonnet (UB.Be enclosed within the locking of accepting on the bellmouth and be stamped locking ring, the locking ring outer ring contacts with accepting a bellmouth inner conical surface, and locking ring has the seam of disconnection.Accepting in the bellmouth has annular seal groove, and seal ring is arranged in the seal groove.On the connection-peg socket outer surface annular groove is arranged, when accepting the connection of head and connection-peg socket joint, the locking ring inner ring embeds in the annular groove.
The utility model has the advantages that simple in structurely, be used for flexible pipe and connect quick and conveniently that locking property is good, as uses plastic production, in light weight, cost is low and long service life.
For clearly demonstrating the technical characterstic of this programme,, this programme is elaborated below by a specific embodiment and in conjunction with its accompanying drawing.
Description of drawings:
Fig. 1 partly cuts open the main schematic representation of looking for the utility model example structure.
Fig. 2 looks schematic representation for the utility model tightening cover embodiment master.
Fig. 3 is Fig. 2 A-A schematic representation.
By accompanying drawing as can be seen, the gladhand of this programme mainly comprises connection-peg 1, accepts 2 and union (screwed)bonnet (UB 3.Flexible pipe 7 is enclosed within connection-peg 1 respectively and accepts on 2 the conical surface and be pushed into root, and threaded together gland 3 clamps flexible pipe 7 with Drop-proof and leakage.Fig. 2, Fig. 3 illustrate locking ring 9 has four to disconnect seam 11, disconnects seam 11 and can make the locking ring 9 rich elasticity that contract, expand, and tightening cover 6 is enclosed within when accepting on 2 bellmouth, and locking ring 9 outer rings withstand on accepts on the 2 bellmouth inner conical surface 4.When accepting the insertion of connection-peg 1 socket in 2 bellmouth, locking ring 9 inner rings embed in the annular groove 5, pin.Seal ring 8 in the seal groove 10 is close on connection-peg 1 socket.Outside when mobile by accepting in 2 the bellmouth when being subjected to external force (as being subjected to displacement or vibrations) effect connection-peg 1, bellmouth inner conical surface 4 is given 9 one restraining forces of locking ring, prevents that locking ring 9 from deviating from annular groove 5, thereby realizes the effect of self-locking anticreep.In use, system is under pressure, and also can present above-mentioned self-locking anticreep phenomenon, system locking, connection-peg 1 with accept 2 between have seal ring 8 to seal not leak system's proper functioning.After the use, when dismantling as need, as long as on the other hand hold connection-peg 1, another hand pinches tightening cover 6 and is pulled outwardly, and locking ring 9 outer rings are left and accepted 2 a bellmouth inner conical surface 4, and locking ring 9 inner rings are just deviate from annular groove 5, connection-peg 1 with accept 2 and separate immediately.
