CN2223405Y - Quickfit bend - Google Patents

Abstract

The utility model discloses the technical proposal of a quickfit bend. The quickfit bend is mainly composed of a bend whose two end ports are provided with outer screws, a tapered short casing tube, and a tapered female lock. An inner screw which is matched with the outer screw on the end port of the bend is arranged at the end port of the tapered female lock. The tapered short sleeve pipe is put in the tapered female lock. The utility model has advantages that the quickfit bend can conveniently, quickly and reliably connect conduits under the condition that connected conduits are not treated. The quickfit bend is especially adapted to use when old conduits are repaired.

Description

The fast-assembling elbow piece

The utility model belongs to a kind of pipe joint, and specifically, it relates to a kind of structure of fast-assembling elbow piece.

Elbow piece is one of main link of various pipes.Existing elbow piece is a bend pipe, and there is internal thread at the two-port place.During use, need cover system outside thread on connected pipe, then, again elbow piece is connected with connected pipe.The main deficiency that above-mentioned prior art exists is: need be to connected pipe dismounting and cover system screw thread, and difficulty of construction is big, and the cycle is long; The dismounting pipe loss is big, uses when being not suitable for old pipeline maintenance especially.

The purpose of this utility model provides a kind of technological scheme of fast-assembling elbow piece.It does not need connected pipe is carried out any processing, pipeline can be coupled together easy construction, quick; Use when being particularly suitable for old pipeline maintenance.

The purpose of this utility model is achieved in that the utility model mainly is made of elbow piece 1, taper short sleeve 2 and taper locknut 3.Elbow piece is a syphon shape, and there is externally threaded bend pipe at the two-port place; There is the internal thread that cooperates with outside thread on the elbow piece port the female port of taper lock; Taper square sleeve pipe places in the taper locknut.During use, the utility model is placed on the pipeline 4 of desire connection, tightens the taper locknut on elbow piece, just finished the connection of pipeline.

Owing to adopted technique scheme, major advantage of the present utility model is: it can not carry out under the situation of any processing connected pipe, convenient, fast, connecting tube reliably; Use when being particularly suitable for old pipeline maintenance.

The drawing of the utility model accompanying drawing is described as follows:

Fig. 1 is a structural representation of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples.In an embodiment, the taper locknut is hexagonal shaped, so that the dismantling device mounting board.Taper short sleeve of the present utility model can be a metallic material, and also nonmetallic material are as rubber or plastic materials.

Claims (2)

1, a kind of fast-assembling elbow piece comprises elbow piece, it is characterized in that: taper short sleeve and the taper locknut that cooperates with elbow piece in addition; There is outside thread at elbow piece two-port place, and there is the internal thread that cooperates with outside thread on the elbow piece port the female port of taper lock, and the taper short sleeve places in the taper locknut.

2, according to the described fast-assembling elbow piece of claim 1, it is characterized in that: the taper locknut is hexagonal shaped outward.
