Abstract

The utility model discloses a tube adapter of downflow-pipe, which comprises a down pipe and an upper pipe connected by tight connection, wherein the head of the upper pipe is jointed by a locking bolt, of which the end of the inner side has screw thread and the other end has a baffle, on which an ''O-shaped''seal ring capable of interference fitting with the upper pipe is arranged, and the connecting head of the down pipe is turned outward for 90 degreesto form a platform, of which the diameter has been matched with the screw thread of the locking bolt, and a gap is opened on the platform; through porcessing, certain angle is formed staggered between the platform surface of both sides of the gap. Compared with the prior art, the utility model is characterized in simple structure, small materials, economic cost, and convenient installment.

Description

A kind of sewer pipe joint

Technical field

The utility model relates to a kind of pipe joint, particularly a kind of sewer pipe joint.

Background technique

Sewer is as the usefulness of effluent discharge, and ducted hydraulic pressure is generally all very little, consider from economic angle, during fabrication tube wall all process very thin, reduce raw material with this, reduce cost.But such structure is being tightly connected of two pipelines has brought difficulty, because of tube wall too thin, can not directly process connecting thread in the tube wall outside, when connecting, need be with externally threaded link in two pipeline junction sockets one, seal with glue between link and the pipeline, and spin with nut at link two.Though such structure has realized being tightly connected of two pipelines, but the generally all thicker length of threaded connector, this can consume more raw materials to a certain extent, increases cost of production, the structure more complicated of whole joint in addition is for fitting operation brings certain difficulty.

The model utility content

The purpose of this utility model is to provide a kind of sewer pipe joint, has simple in structure, cost economy, characteristics easy for installation.

For achieving the above object, the utility model is by the following technical solutions:

A kind of sewer pipe joint, comprise the last pipeline and the following pipeline that will be tightly connected, it is characterized in that: described pipe end socket one lock nut of going up, the inboard end of lock nut is provided with screw thread, the inboard the other end is provided with a retaining platform, be provided with on the retaining platform one can with " O " RunddichtringO of last pipeline interference fit; Turn up 90 ° and form a platform in the connecting port of described down pipeline, the screw thread of platform diameter and lock nut matches, and has a breach on the platform, makes the table top of breach both sides certain angle that staggers by processing simultaneously.

Above-mentioned last outer diameter tube and following pipeline endoporus match, and the former gos deep into the certain distance of the latter after installation.

Adopt the following pipeline platform of above structure to form an externally threaded structure, directly can be connected with the internal thread spiral of lock nut inside lower end.In use, at first " O " RunddichtringO is put into the lock nut endoporus, make pipeline pass lock nut and seal ring successively subsequently, the frictional force of utilizing seal ring and its interference fit and forming realizes both being tightly connected, subsequently the following pipeline of the band breach platform that processes is screwed in lock nut, can realize that the sealing of upper and lower pipeline is connected.Whole joint structure is simple, materials are few, fitting operation is very convenient.

Embodiment

Shown in Fig. 1,2,3 and 4, a kind of sewer pipe joint, comprise the last pipeline 1 and the following pipeline 2 that will be tightly connected, here, last pipeline 1 port socket one lock nut 3, lock nut 3 inboard ends are provided with screw thread 31, the inboard the other end is provided with a retaining platform 32, install on the retaining platform 32 one can with " O " RunddichtringO 4 of last pipeline 1 interference fit, seal ring 4 usefulness elastic materials are made, because of sewer is mainly used in sewage emissions, pressure wherein is very little, and the frictional force that seal ring 4 forms with last pipeline 1 interference fit can realize both being tightly connected fully.

Turn up 90 ° and form a platform 21 in the connecting port of following pipeline 2, the screw thread of platform 21 diameters and lock nut 3 matches, for making whole platform 21 form an externally threaded structure, on platform 21, have a breach 211, and make the table top of breach 211 both sides certain angle that staggers by processing, be convenient to be connected with internal thread 31 spirals of lock nut 3 inside lower end, simultaneously because of 21 on the whole platform angle that staggers at breach 211 places, other positions still are in the same plane, this makes and closes in the process stubborn, force whole platform 21 to be out of shape gradually and match, and finish the intensity that has guaranteed under the restoring force that rear platform 21 is installed that both connect with the screw thread 31 of lock nut.

In use, at first " O " RunddichtringO 4 is put into and tightened nut 3 endoporus, make pipeline 1 pass lock nut 3 and seal ring 4 successively subsequently, and the following pipeline 2 screw-in lock nuts 3 of the band breach platform 21 that processes, match because of last pipeline 1 external diameter and following pipeline 2 endoporus simultaneously, pipeline 1 gos deep into the certain distance of its endoporus gradually on pipeline 2 screws in the process of lock nut 3 down, the sealing that promptly realizes upper and

lower pipeline

1,2 is connected, and whole joint structure is simple, materials are few, fitting operation is very convenient.

Claims

1, a kind of sewer pipe joint, comprise the following pipeline and the last pipeline that will be tightly connected, it is characterized in that: described pipe end socket one lock nut of going up, the inboard end of lock nut is provided with screw thread, the inboard the other end is provided with a retaining platform, be provided with on the retaining platform one can with " O " RunddichtringO of last pipeline interference fit; Turn up 90 ° and form a platform in the connecting port of described down pipeline, the screw thread of platform diameter and lock nut matches, and has a breach on the platform, makes the table top of breach both sides certain angle that staggers by processing simultaneously.

2, a kind of sewer pipe joint as claimed in claim 1 is characterized in that: the described outer diameter tube that goes up matches with following pipeline endoporus, and the former gos deep into the certain distance of the latter after installation.
