Description

Improved generation drain pipe seal structure

Technical Field

The utility model belongs to air conditioner accessory field, concretely relates to improved generation drain pipe seal structure.

Background

In the process of discharging condensed water in an automobile air conditioning system to the outside of an automobile, a common method is to connect a rubber drain pipe with an air conditioning main body and then open a hole on a metal plate of the automobile body, the rubber drain pipe leads water to the outside of the automobile after penetrating through the metal plate hole of the automobile body, and the sealing between the drain pipe and the metal plate of the automobile body is very important and air, dust, bacteria, noise and the like outside the automobile cannot enter the automobile.

At present, the sealing treatment mode of the drain pipe and the sheet metal part of the vehicle body is mostly to adopt a sealing structure made of rubber arranged on the drain pipe, so that the drain pipe is tightly attached to the sheet metal part and achieves the sealing effect, as shown in fig. 2. But in current structure, the drain pipe is mostly split type with the sealing member, and is difficult for fixing, has the phenomenon of leaking, increases the rework process. Although some manufacturers also propose an integrated sealing structure, after the sealing element is used for a long time, the joint of the sealing element is easy to loosen due to aging of rubber, a larger gap exists, the water leakage phenomenon is still easy to occur, and the replacement difficulty is high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an improved generation drain pipe seal structure to solve the above-mentioned defect that leads to among the prior art.

The utility model provides an improved generation drain pipe seal structure, includes drain pipe and sealing member, sealing member integrated into one piece is on the drain pipe and lie in the outer wall of drain pipe, the sealing member includes upper seal piece and lower gasket, and the outward flange downwarping of upper seal piece, the outward flange kickup of lower gasket form an annular seal groove between upper seal piece and the lower gasket, and the bottom surface of upper seal piece still is equipped with at least one annular rib, be equipped with a pressfitting structure on the drain pipe of upper seal piece top to adjust the packing force of sealing member and sheet metal component.

Preferably, the pressing structure comprises a sleeve and a pressing sleeve, the outer surface of the sleeve is provided with an external thread and is fixed on the drain pipe, the sleeve is in threaded connection with the pressing sleeve, and the lower end of the pressing sleeve is provided with a flange end face and is abutted to the upper sealing sheet.

Preferably, the number of the ribs is two, the protruding length of the ribs is the same, and the upper sealing sheet is bent downwards to form a V shape.

Preferably, the sleeve and the pressing sleeve are made of the same material as the drain pipe.

The utility model has the advantages that: through designing sealing member and drain pipe into an organic whole, reduced its assembly degree of difficulty, it is easily fixed, improved sealing performance, the difficult phenomenon that leaks that exists, and through set up the pressfitting structure that can adjust sealing member and sheet metal component packing force on the drain pipe of sealing member top, can appear under the not hard up condition of fatigue in the sealing member, screw downwards and compress tightly the cover, can realize the inseparable laminating of sealing member and sheet metal component, need not to change whole drain pipe structure, reduced the maintenance cost.

Drawings

Fig. 1 is a cross-sectional view of the present invention.

FIG. 2 is an assembly view of a conventional drain pipe, a sealing structure thereof and a sheet metal part

The device comprises a water discharge pipe 1, a sealing element 2, an upper sealing sheet 21, a lower sealing sheet 22, a sealing groove 23, ribs 3, a sleeve 4, a pressing sleeve 5, a flange end face 51 and a sheet metal part 6.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1, an improved drain pipe sealing structure comprises a drain pipe 1 and a sealing member 2, wherein the sealing member 2 is integrally formed on the drain pipe 1 and located on the outer wall of the drain pipe 1, the sealing member 2 comprises an upper sealing sheet 21 and a lower sealing sheet 22, the outer edge of the upper sealing sheet 21 is bent downwards, the outer edge of the lower sealing sheet 22 is bent upwards, an annular sealing groove 23 is formed between the upper sealing sheet 21 and the lower sealing sheet 22, at least one annular rib 3 is further arranged on the bottom surface of the upper sealing sheet 21, and a pressing structure is arranged on the drain pipe 1 above the upper sealing sheet 21 to adjust pressing force of the sealing member 2 and a sheet metal part 6. The sealing element 2 is made of rubber and has certain elasticity.

In this embodiment, the pressing structure includes a sleeve 4 and a pressing sleeve 5, the outer surface of the sleeve 4 is provided with an external thread and is fixed on the drain pipe 1, the sleeve 4 is connected with the pressing sleeve 5 through the thread, and the lower end of the pressing sleeve 5 is provided with a flange end face 51 and abuts against the upper sealing sheet 21.

In this embodiment, there are two ribs 3, and the protruding length of the two ribs is the same, and the upper sealing sheet 21 is bent downward to form a "V" shape. And two ribs 3 are all located the same side of "V" font, and when upper seal piece 21 was compressed tightly downwards, rib 3 can form a sealing washer again, so can play the effect of supplementary sealed.
