Abstract

The utility model provides a hose quick joint. Two opposite main bodies and the end head of an inner core seat which is matched with the two opposite main bodies are respectively provided with a section of inner and outer threads which are matched; the end surface is inlaid with a sealing ring to realize the seal and the quick screw connection of the end surface; the thread at the tail section of each of the main bodies is connected with a joint of a end cover or a water valve or a water gun which is tightly clamped with a hose; correspondingly, the tail section of the inner core seat can be a pipe joint connected with the hose and can also be a reduced section embedded with a sealing washer and connected with other joints. The utility model has the advantages of quick butt joint, reliable strength, little sealing element abrasion and long service life; the utility model is not only suitable to be used as the quick joints of water pipes but also suitable to be used as the quick joints of hydraulic and pneumatic pipe lines.

Description

Gladhand

The utility model relates to a kind of gladhand, especially a kind of rapid pipe joint of supply pressure liquid hose.

Flexible pipe between automatic washing machine and the hydrant connects, the particularly press water supply of the long distance of water-supply source relatively when green area irrigation, equipment cleaning, need several sections flexible pipes to be connected, operation all with or hope use rapid pipe joint, but domestic and international normally used inserted type quick coupling is to provide radially pin, groove to lock by spring force at the clutch component of realizing butt joint mutually at present, and because this splice seal is subjected to the friction of inserting member, so sealing and reliability are stable inadequately, after the too high or of a specified duration usefulness of hydraulic pressure, come off easily, seepage.

The purpose of this utility model is to provide a kind of rapid pipe joint of adopting rotary connection.The purpose of this utility model is achieved in that a kind of gladhand, clutch component, Sealing and pipeline fastener with mutual butt joint, it is characterized in that: clutch component is made up of a pair of main body and internal core print seat, each main body is the cylinder of an axial hollow, the internal chamber wall at its middle part radially has a circle projection, shaft pertaining is to the internal thread that one section projection is arranged, and afterbody is threaded; T-shaped and the tape spool of each internal core print seat is to runner, its convex shoulder rides on the projection of main body inner chamber, the termination one section outside thread that can screw with the internal thread that docks the main body termination radially arranged, with this mutual butt joint that realizes a pair of main body and internal core print seat with separate, the internal core print seat end face has a groove for the embedding of O RunddichtringO, the degree of depth of this groove is less than the diameter of O RunddichtringO, so that separately O RunddichtringO not only overlaps on a pair of internal core print seat in butt joint back, and compression seal.

Certainly the afterbody of internal core print seat both can be a pipe joint, with affixed flexible pipe, can be again a necking down, fill corresponding seal washer after, make to have the inipple that connects with other member, with main body tailing screw flight sealed attachment.

Each makes coupling with one section screw thread owing to adopt pair of joint, not only makes the flexible pipe butt joint fast, even and big pressure is arranged in the pipe, as long as two place's screw threads of working in coordination in the working strength scope, still can positive connection.In addition, the butt joint end face overlaps the fashion of extrusion sealing with two O RunddichtringOs, makes Sealing frayed little, and not yielding, the life-span is long, good sealing effect.Adopt different internal core print seat tail structures and the annex of joining, can make the rapid abutting joint of flexible pipe and flexible pipe, the rapid abutting joint of pressure hydraulic giant and flexible pipe can also be made the rapid abutting joint of water valve and flexible pipe, rapid pipe joint that can not only used as water pipe also can be done the rapid pipe joint of hydraulic pressure, air-pressure duct.

Below with accompanying drawing in conjunction with the embodiments, structure of the present utility model is described in further detail again:

A kind of embodiment's of gladhand that Fig. 1 provides for the utility model whole-cutaway view.

Fig. 2 is the A joint worm's eye view after the rapid pipe joint of Fig. 1 structure is freed.

Fig. 3 is the B joint plan view after the rapid pipe joint of Fig. 1 structure is freed.

Fig. 4 is second kind of embodiment's of gladhand a half sectional view.

Fig. 5 is the third embodiment's of gladhand a half sectional view.

Shown in Figure 1 is the rapid pipe joint of two sections flexible pipes, and one section internal thread 4.1 of each main body 4 end face screws with 5 one sections outside threads of internal core print seat of butt end.Two O RunddichtringOs 6 that are sleeved on the internal core print seat end face embedding on the main body middle part projection 4.2 overlap, and are subjected to the extruding to relay, implement end face seal.The cylinder of the main body 4 of a pair of rapid pipe joint is anti-skidding male and fomale(M﹠F), and make the sign that two joints begin to dock with the convex tendon 4.3 that the relevant position is provided with, two convex tendons 4.3 on two joints are in when overlapping the position, as Fig. 2, Fig. 3, shown in, the internal thread 4.1 of the one section projection in A adapter body 4 terminations just in time embeds in the arcuation neutral gear 7 of B joint, simultaneously, the internal thread 4.1 of the one section projection in B adapter body 4 terminations also just in time embeds in the arcuation neutral gear 7 of A joint.Through rotation, the internal thread 4.1 on each main body just in time screws in the internal core print seat outside thread 5.1 of butt end.In order to limit the relative swing of two main bodys, therefore the corresponding positions in each main body inner wall installs a location plush copper 4.5.The joint 9 of the locking closure 2 of the screw thread 4.4 confession lock ring flexible pipes 1 of each main body afterbody or water valve, hydraulic giant connects.The afterbody of internal core print seat 5 can be a pipe joint 5.2.The pipeline fastening member is formed by waling the flexible pipe 1 and the beam ring 3 of band elastic groove and the locking closure 2 that connects with the main body tailing screw flight, and the termination of locking closure internal diameter is tapered and inconsistent with beam ring 3, and rotating locking closure 2 can wedging beam ring 3, banding flexible pipe 1.If the afterbody of a main body is and other member scyewed joint, then as Fig. 4, shown in, the afterbody of internal core print seat 5 can be a necking down 5.3, its interface just in time with main body inner chamber radial protrusion 4.2 in one plane, form the groove of Gong seal washer 8 embeddings of an annular.Have the inipple that connects with other member, with main body tailing screw flight sealed attachment.As shown in Figure 5, if with high pressure water gun coupling head 9 sealed attachment after, can use high pressure water gun to carry out equipment cleaning.
