Description

L type rotation quick inserting joint

Technical field

The utility model discloses a kind of L type rotation quick inserting joint, be mainly used in the pipe connection systems such as Oil, Water, Gas in the various machinery, belong to the pipeline connecting parts technical field.

Background technique

Pipe joint is widely used in oil, water, connection between delivery lines such as gas, generally can be divided into straight coupling, L type joint, T connector, wherein L type joint comprises L type joint body, and respectively be provided with screw thread at the two end part of L type joint body, during butt joint, as long as the nut driving that will be arranged on the flexible pipe can be realized the pipeline purpose of connecting at the screw thread place of L type joint body, but in the process that connects, generally need just can reach the purpose of tightening by tool wrench, butt joint is time-consuming like this, effort, butt joint speed is slow, and L type joint also exists such problem: after an end of L type joint is connected with flexible pipe and tightens, the other end must be fixed in one direction, and the tip side on this direction can not guarantee and can just be connected with another pipeline, one end that may need the to tighten angle of circling round will reduce the sealability of its connection like this.

The model utility content

For addressing the above problem, it is a kind of simple in structure that the utility model purpose is to provide, and butt joint is convenient, and have stable tightness and the L type rotation quick inserting joint of an end with spinfunction wherein.

The technological scheme that its technical problem that will solve the utility model adopts is: a kind of L type rotation quick inserting joint, comprise L type joint body, in L type joint body, has L type ladder hole, end at L type joint body is connected with a nut, this nut can rotate mutually with L type joint body, the other end at L type joint body is inserted with a degree of tightness riveting, this degree of tightness riveting is inserted in the L type ladder hole, and between L type ladder hole and degree of tightness riveting, be equipped with a lining, bottom in the degree of tightness riveting also is provided with a shell fragment, and this shell fragment is resisted against the shoulder place in the L type ladder hole.

Of the present utility modelly further be set to: described nut is made of a convex shoulder, each axle journal of convex shoulder both sides, be provided with a circle curve bath at described convex shoulder place, and the end of the L type joint body that is connected with nut is provided with an annular flange flange, and this annular flange flange and curve bath are combined together.Setting can be with nut and L type joint body close-fitting together like this, and can rotate mutually.

One axle journal of described nut puts in the L type ladder hole, and is provided with a seal ring I on this axle journal, and the outer surface on another axle journal of nut has screw thread.Setting can improve the sealing between nut and the L type joint body like this, prevents that leakage situation from appearring in fluid.

Described shell fragment is resisted against on the seal ring II, and seal ring II is resisted against the shoulder place in the L type ladder hole.Setting can improve the sealing in the L type ladder hole like this.

Described shell fragment is circular, and along its circumferencial direction and inwardly be set side by side with 8～12 gear pieces, setting can improve the shell fragment flexibility like this, increases adhesion, prevents to get loose after the pipe end insertion.

After the utility model adopts said structure, after nut is connected with pipe fitting and tightens, L type joint body can rotate on nut, by rotate determine L type joint body towards, at this moment, described degree of tightness riveting just can be connected with other flexible pipe, so just need not reduce the connection that sealing just can be finished pipeline.When above-mentioned degree of tightness riveting is connected with flexible pipe,, and passes shell fragment and can finish the butt joint purpose, dock very convenient as long as flexible pipe injects in the degree of tightness riveting.
