Abstract
The utility model relates to the technical field of a pipe joint, and is designed for reinforcing the connection of a pipe joint. An annular slot is arranged in a joint nozzle of a joint body, and a seal ring is lined in the annular slot outside which a pipe strap is butted. A nut which is arranged outside the pipe strap is connected with the joint by screw threads. The utility model is characterized in that the front part of the pipe strap forms a circular ring shape, and the rear part forms a conic table shape. A plurality of open slots are evenly milled on the circumference. The utility model has the advantages of good radial contraction force, firm connection and convenient use, and is suitable for pipe connection.
Description
The utility model relates to a kind of pipe joint technical field.
Often will use quick coupling on family's tap water pipeline, it has uses fast, makes things convenient for advantage to facilitate as people's daily life.Whether but also there are problems in quick coupling, good as sealability, whether connects strong, durable.As the patent No. is that 92219155.7 Chinese patent " improves the inclined-plane sealed pipe joint of sealability ", it is made of body, sealing gasket, pipe clamp and nut, it has selected rational inclination angle of inclined plane and pipe clamp inclination angle, the sealability and the chucking power of pipe joint have been improved, its shortcoming is that pipe clamp only is the bevelled taper type of appearance, radially essentially no contraction strength is become flexible easily, is come off or leak so is embodied in pipe joint last time of connection one length, and it is reliable that connection power is still understable.
The purpose of this utility model be to provide a kind of radial contraction power good, make pipe joint connect more reliable and more stable, be difficult for the loosening quick coupling that leaks.
The technical solution of the utility model is to realize like this.This quick coupling includes union body, seal ring, pipe clamp, nut, union body one end inserts the connection port mouth inner face that connects for pipe and has circular groove, groove liner seal ring, there is the pipe clamp that is placed in outer tube surface on outer top, pipe clamp has the nut that is placed in outside the pipe outward, nut one end opening is shaped on the inclined-plane and cooperates with the pipe clamp ramp, the other end is shaped on internal thread and the joint surface outside thread is connected, it is characterized in that described pipe clamp is divided into front and back two-part, forward part is ring, the rear section is the taper type that cooperates with inclined-plane in nut one end opening, and frustum evenly is milled with many opening slots on circumference.
Evenly be milled with cross opening slot or Y font opening slot on the above-mentioned frustum circumference.
The design of frustum opening slot is adopted in this quick coupling pipe clamp rear section, make pipe clamp in nut, can laterally withstand seal ring under the ramp effect, can radially evenly shrink again and block adapter, so sealing and connectivity robustness are all good, and the cost increase seldom, the suitable especially manufacturing of stainless steel material cold-press process, the reduction consumable quantity advantage of adopting.
Description of drawings:
Fig. 1. quick pipe connecting header structure cut-away view;
Fig. 2. the pipe clamp structural representation;
Fig. 3. the pipe clamp front view.
Below in conjunction with description of drawings embodiment of the present utility model is described in further detail:
As shown in the figure, this quick coupling includes union body 1, seal ring 4, pipe clamp 3, nut 2, union body can be made two and lead to, threeway, four-way, specifications such as two logical elbows, one end inserts the connection port mouth inner face that connects for pipe and has circular groove, can make ring, two O RunddichtringOs of liner, perhaps make taper type, liner inclined-plane seal ring, there is the pipe clamp that is placed in outer tube surface on outer top, two-part before and after pipe clamp is divided into, forward part 3a is ring, rear section 3b is taper type, evenly is milled with " ten " font opening slot or " Y " shape opening slot 3c on the frustum circumference, and pipe clamp has the nut that is placed in outside the pipe outward, nut one end opening is shaped on the inclined-plane and matches with frustum inclined-plane, pipe clamp rear section, and the other end is shaped on internal thread and the joint surface outside thread is connected.
Its using method is as follows: pipe one end is inserted in earlier two 0 shape seal rings, pipe clamp and nuts in advance, and fittings body joint one end inserts pipe then, tightens to be connected with nut and fittings body to get final product.
Claims (4)
