Technical Field

The utility model relates to a downcomer field especially relates to a retractable downcomer structure.

Background

The downcomer is as daily kitchen bathroom essential thing, and drainage pipe's length is fixed, can only select the pipeline of suitable length in advance according to the on-the-spot needs, but often can not be the same with what expect during the installation, and we need a more nimble pipeline, can adjust in a flexible way.

SUMMERY OF THE UTILITY MODEL

The utility model provides a retractable sewer pipe structure to the fixed shortcoming of prior art pipeline length.

In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the utility model provides a retractable downcomer structure, includes that first body and cover locate the second body in the first body, has seted up the seal groove on the side of second body external diameter, and the cover is equipped with sealing washer one in the seal groove, and second body external diameter is less than the extension section of seal section including seal section and external diameter, and on the seal section was located to the seal groove, the extension section external diameter was gone up and is equipped with many butt strips along the central axis direction, and butt strip height-equals seal section radius and extension section radius difference between them.

Adopt above-mentioned scheme, the second body cover is sealed through sealing washer one in locating first body, and when sealed section and extension section were located first body simultaneously, the extension section than sealed section external diameter littleer can save the material, be located the butt strip on the extension section can with first body internal diameter butt, the butt strip makes and is difficult for rocking relatively in first body with sealed section.

As preferred, seted up a plurality of draw-in grooves on the butt strip, the draw-in groove degree of depth equals the butt strip height, and a plurality of draw-in grooves set up along butt strip the central axis direction evenly at an interval side by side, and on the first body external diameter and towards being used for the cover to establish second body pot head and be equipped with sealing washer two, and sealing washer two is its internal diameter of annular and is the echelonment, and two internal diameters of sealing washer are including the major diameter that the cover was located on the first body and can be with the.

By adopting the scheme, the second sealing ring can be clamped with the clamping groove, so that the butt strip is ensured to be difficult to shake relatively with the sealing section in the first pipe body, and the sealing performance is further enhanced.

Preferably, the number of the abutment bars is two, and the two abutment bars are respectively located at both ends of the extension section having the same outer diameter.

By adopting the scheme, the two abutting strips are symmetrically arranged, so that the material is saved most.

Preferably, the number of the abutment strips is two or more, and the distance between the abutment strip and the adjacent abutment strip is equal.

Adopt above-mentioned scheme, many butt strips can prevent more that sealed section from rocking more difficult in first body.

Preferably, the inner diameters of the sealing section and the extension section are the same.

By adopting the scheme, the inner diameters are the same, and the processing is convenient.

As preferred, be used for the cover to establish second body one end on the first body and be equipped with the chamfer of being convenient for second body and the entering of sealing washer.

By adopting the scheme, the chamfer is convenient for the second pipe body and the first sealing ring to enter the inner diameter of the first pipe body.

The utility model discloses owing to adopted above technical scheme, have apparent technological effect: the second pipe body sleeve is arranged in the first pipe body and is sealed through the first sealing ring, when the sealing section and the extension section are located in the first pipe body simultaneously, the extension section is smaller than the outer diameter of the sealing section, materials can be saved, the butt strip located on the extension section can abut against the inner diameter of the first pipe body, the butt strip enables the sealing section to be difficult to shake relatively in the first pipe body, the sealing performance is enhanced through the second sealing ring, and the chamfer is convenient for the first pipe body and the first sealing ring to enter the inner diameter of the first pipe body.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The first embodiment is as follows:

the utility model provides a retractable downcomer structure, at first refers to fig. 1 and fig. 2, includes that first body 1 and cover locate the second body 2 in first body 1, first body 1 and second body 2 all are the pipe form, and second body 2 includes sealed section 3 and extension section 4 that the external diameter is less than sealed section 3, and both diameters are the same and both the central axis coincidence in sealed section 3 internal diameter and extension section 4 internal diameter. The side that is located 3 external diameters of seal section has seted up round seal groove 5, and seal groove 5 is the coincidence of annular central axis and 3 the central axis of seal section, is located seal groove 5 endotheca and is equipped with a sealing washer 6, and in seal section 3 stretched into first body 1 earlier with its seal section 3 of extension section 4, sealing washer 6 received the extrusion of 1 internal diameter of first body and accomplished the seal between seal section 3 and the 1 internal diameter of first body.
