Abstract

The utility model discloses a reed-type quick coupling which comprises a first joint and a second joint which are respectively connected with two pipelines and mutually inserted. One end of the first joint, inserted into the second joint, is provided with a clamping table; one end of the second joint, inserted with the first joint, is fixed with a plurality of reeds; one end of the reed is fixed on the periphery of the second joint, and the other end thereof extends into the second joint from the through hole of the second joint; a clamping sleeve is movably sheathed on the second joint; and the clamping sleeve is sheathed on the reed to push against the reed to lead the other end of the reed to extend into the second joint and be clamped on the clamping table of the first joint. The clamp-on quick coupling not only solves the problem of quick connection, but also realizes bidirectional quick operation of installment and detachment, thus bringing great convenience for installment and detachment and improving the reliability of all connection parts.

Description

Spring-piece type rapid pipe joint

Technical field

The utility model relates to pipe joints such as a kind of water route or gas circuit, refers to a kind of spring-piece type rapid pipe joint especially.

Background technique

In the bathroom industry, in every field such as industrial production, usually can relate to the connection of two water routes, gas circuit or oil circuits or the like pipeline, pipe fitting joint is exactly a kind of accessory of being connected between pipeline and the pipeline of being widely used in.Traditional pipe fitting joint usually adopts and is threaded, and installs that difficulty, setting tool are difficult looks for, seals problems such as unreliable yet be threaded but to exist, and must spend the more time when installing can screw tight especially at every turn.Also have at present the different rapid pipe joint of many types structure, it can connect two pipelines apace, but existing rapid pipe joint much all can only be accomplished or install or dismantle is quick operation, can't realize installing and dismantling two-way quick operation, so still give and install and keep in repair and bring bigger trouble.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of clamp band type rapid pipe joint, and it not only can connect fast, also can realize the two-way quick operation of installing/dismounting, and connection simple in structure is reliable.

For solving the problems of the technologies described above, technical solution of the present utility model is:

A kind of spring-piece type rapid pipe joint comprises first joint and second joint that are connected with two pipelines respectively and peg graft mutually; The end that described first joint inserts within second joint is provided with Ka Tai; The end that described second joint and first joint are pegged graft mutually is fixed with some shell fragments, and an end of this shell fragment is fixed on the second joint periphery, and the other end is stretched in second joint from the through hole on second joint; Also activity is with a cutting ferrule on this second joint, and after this cutting ferrule was placed in outside the above-mentioned shell fragment, compressing shell fragment, to make its other end stretch in second joint inner and can be stuck on the Ka Tai of first joint.

Described shell fragment is L shaped; The inboard end to end from relative shell fragment of described cutting ferrule is provided with tilted guide surface, fixed groove and block face successively; In the time of outside cutting ferrule is placed in shell fragment, the L shaped drift angle of shell fragment fastens in fixed groove.

Described shell fragment one end is fixed or is directly molded on the retainer ring, this retainer ring then is enclosed within on the necking down step of the described second joint periphery, also be provided with a groove on this step, a card is stuck in this groove retainer ring is fixed on second joint, and then described shell fragment is fixed.

The end that described first joint inserts within second joint also is provided with Sealing.

After adopting such scheme, the utility model adopts the shell fragment back-off structure, and by the cutting ferrule screens; In when assembling, directly insert first joint, shell fragment promptly can be lived first joint by back-off, thereby prevents that first joint from deviating from; During dismounting, push away cutting ferrule on then, shell fragment promptly can be upspring, and it is promptly detachable to touch post-tensioning first joint then earlier.This clamp band type rapid pipe joint has not only solved quick connectivity problem, has also realized the two-way quick operation of installing/dismounting, brings great convenience for installation and maintenance, and can improve the reliability of each attachment portion.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

What the utility model disclosed is a kind of spring-piece type rapid pipe joint, consults Figure 1 and Figure 2, is preferred embodiment of the present utility model.Described rapid pipe joint comprises first joint 1 and second joint 3 that is connected with two pipelines respectively, and activity is with a cutting ferrule 2 on second joint 3.Wherein:

The end that described first joint 1 inserts within described second joint 3 is provided with Sealing 11, also is provided with card platform 12.

The end that described second joint 3 and first joint 1 are pegged graft mutually is fixed with some shell fragments 4, and an end of this shell fragment 4 is fixed on second joint, 3 peripheries, and the other end is stretched in second joint, 3 inside from the through hole 31 on second joint 3.The structure of fixing described shell fragment 4 is a lot, in the present embodiment, described shell fragment 4 one ends are fixed or are directly molded on the

retainer ring

41,41 of this retainer rings are enclosed within on described second joint, the 3 periphery necking down steps 32, also be provided with a groove 33 on this step 32, thereby a card 5 is stuck in this groove 33 described retainer ring 41 is fixed on second joint 3, and then described shell fragment 4 is fixed.In addition, this shell fragment 4 can be L shaped.

Described cutting ferrule 2 (cooperating shown in Figure 5) is placed in outside second joint 3, and its inboard end to end from above-mentioned relatively shell fragment 4 is provided with tilted guide surface 21, fixed groove 22 and block face 23 successively.The effect of described tilted guide surface 21 is in order smoothly cutting ferrule 2 to be pushed away the outside that snaps into shell fragment 4; 22 of described fixed grooves snap in it for the L shaped drift angle that makes shell fragment 4 and locate, so that make shell fragment 4 free ends stretch within second joint 3, and the fixing state of fixation spring tab 4 and cutting ferrule 2; 23 of described block faces are in order to withstand shell fragment 4 exterior edge faces, prevent that cutting ferrule 2 from deviating from downwards.

The installation step of rapid pipe joint described in the utility model is as follows:

Step 1: as shown in Figure 3, earlier described cutting ferrule 2 is placed in shell fragment 4 outer ends on second joint 3, and makes the L shaped drift angle of shell fragment 4 fasten fixed groove 22 in cutting ferrule 2, yet within will described first joint, 1 insertion, second joint 3.

Step 2: as shown in Figure 4, make the card platform 12 on first joint 1 cross the other end end of described shell fragment 4, thereby make shell fragment 4 back-offs live first joint 1, it is not got loose (as shown in Figure 5).

When dismounting, as shown in Figure 6, cutting ferrule 2 is upwards pushed away, make its pressure of decontroling shell fragment 4 fasten state, shell fragment 4 will be upspring, as shown in Figure 7, earlier first joint 1 is touched to second joint, 3 directions then, can pull out first joint 1 afterwards, finish unloading process (as shown in Figure 8).
