Abstract

That the utility model proposes a kind of structures is simple, production cost is low, the bidirectional bayonet retaining connector that water pipe can be effectively prevent to be detached from, including socket joint ontology, both ends on the socket joint ontology offer undertaking opening respectively, water pipe is equipped in the undertaking opening, the sealing device for sealing the socket joint ontology mutually with the water pipe is provided on the socket joint ontology, the undertaking open inner tube wall offers several limiting grooves, is provided with the retention bead matched in the limiting groove on the water pipe periphery.

Description

Bidirectional bayonet retaining connector

Technical field

The utility model relates to spigot-and-socket pipe construction applications, more particularly, to bidirectional bayonet retaining connector.

Background technique

There is a universal technological deficiency, the pipe being connected in the flexible connection between the pipe fitting of existing Push-fit Anticreep performance between part is incomplete, and easily there is a phenomenon where the pipe fittings having connected to be separated under external force, to construction Very big difficulty is brought, not only increases construction volume, but also delay construction speed.

Utility model content

Therefore, for above-mentioned problem, that the utility model proposes a kind of structures is simple, production cost is low, can effectively prevent The bidirectional bayonet retaining connector that antipriming pipe is detached from.

To realize above-mentioned technical problem, the solution that the utility model is taken are as follows: bidirectional bayonet retaining connector, including hold Ontology is inserted, the both ends on the socket joint ontology offer undertaking opening respectively, are equipped with water pipe in the undertaking opening, described to hold It inserts and is provided with the sealing device for sealing the socket joint ontology mutually with the water pipe on ontology, the undertaking open inner tube wall opens up There are several limiting grooves, is provided with the retention bead matched in the limiting groove on the water pipe periphery.

Further improved to be, the sealing device includes stop collar, the sealing ring for being set to the socket joint body interior, For the stop collar along the socket joint ontology radially around setting, the sealing ring is set to the stop collar close to undertaking open end Face, the limiting groove are opened between the sealing ring and undertaking opening.

Further improved to be, the limiting groove opens up depth and is inwardly gradually reduced from undertaking opening.

Further improved to be, the limiting groove is four.

Further improved to be, the opening inner circumferential of accepting offers the notch for facilitating the water pipe insertion.

Further improved to be, the retention bead is tooth form retention bead.

Further improved to be, the retention bead is set to the water pipe by elastic piece.

By using preceding solution, the beneficial effects of the utility model are: water pipe can be effectively prevent from socket joint sheet It falls off in body, and by pressing elastic piece, water pipe can be made rapidly mutually to separate with socket joint ontology, substantially increase construction effect Rate guarantees construction speed, further decreases the labor intensity of worker.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model embodiment bidirectional bayonet retaining connector.

Specific embodiment

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

Revealed with reference to Fig. 1 the utility model embodiment is bidirectional bayonet retaining connector, including socket joint ontology 2, described Both ends on socket joint ontology 2 are respectively arranged with undertaking opening, undertakings be open in be equipped with water pipe 1, in the socket joint ontology 2 Portion is equipped with stop collar 4, sealing ring 41, and along the socket joint ontology 2 radially around setting, the sealing ring 41 is set the stop collar 4 The stop collar 4 is placed in close to accepting open end, 2 inner tubal wall of socket joint ontology opens up that there are four limiting groove 5, the limits Position groove 5 is opened between the sealing ring 41 and undertaking opening, and the limiting groove 5 opens up depth and opens from the undertaking Mouth is inwardly gradually reduced, and the outer tube wall of water pipe 1 is provided with the tooth form retention bead 31 matched in the limiting groove 5, described The two sides of sealing ring 41 are inconsistent respectively at the nozzle end of the water pipe 1 and stop collar 4, realize sealing function.

In order to facilitate water pipe insertion, the opening inner circumferential of accepting offers the notch 51 for facilitating water pipe to be inserted into.

In order to facilitate separation water pipe and socket joint ontology, the tooth form retention bead 31 is set to the water by elastic piece 3 Pipe 1.

The modifications and changes done with this creation, all belong to the scope of the patents of this creation opinion, and are not limited to embodiment and are taken off The person of showing.
