In some modes, an annular isolating ring is concentrically arranged on the periphery of any fixing hole.

In some modes, the outer wall of the lower part of the pipe body is provided with a sealing concave part.

In some modes, the refrigerated container water leaking device connecting piece is made of TPV materials.

In some forms, the inner wall of the upper end of the tubular body is provided with an internal thread portion.

In some forms, the tubular body, the annular skirt portion, and the lower portion of the tubular body are integrally formed.

In some forms, a rigid retainer ring is disposed in the annular skirt portion.

In some modes, an annular concave part is arranged on the lower side face of the annular skirt edge part, and the fixing holes are uniformly distributed in the annular concave part.

The utility model has the beneficial effects that:

has better sealing effect. The service life of the connecting piece is prolonged, and the maintenance cost is reduced; the fixing screw is better protected.

Drawings

FIG. 1 is a schematic perspective view of the present invention;

FIG. 2 is a schematic cross-sectional view of the present invention;

FIG. 3 is a partial schematic view of the present invention;

fig. 4 is a schematic view of the structure of the annular skirt portion of the present invention.

In the figure:

the sealing structure comprises a 100-tube-type body, a 200-annular skirt part, a 210-inner-side annular sealing convex part, a 220-outer-side annular sealing convex part, 230 fixing holes, a 240-annular blocking ring, a 250-annular inner concave part, a 300-tube-body lower part, a 310-sealing concave part and a 400-inner threaded part.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

refrigerated container weeper attachment, as in FIG. 1, comprises

A tube-type body 100 having a shape of a tube,

referring to fig. 2, the annular skirt 200 is disposed outside the tubular body 100, and has a plurality of fixing holes 230 disposed around the center of the annular skirt 200, at least two concentrically disposed outer annular sealing protrusions 220 are disposed outside the plurality of fixing holes 230, at least two concentrically disposed inner annular sealing protrusions 210 are disposed inside the plurality of fixing holes, the inner annular sealing protrusions 210 and the outer annular sealing protrusions 220 are disposed on the upper side of the annular skirt 200,

the lower portion 300 of the pipe body is disposed at the lower portion of the pipe body 100, and the inner diameter thereof is gradually reduced from the top to the bottom.

As shown in fig. 3, an annular spacer 240 is concentrically disposed around any one of the fixing holes 230. The annular blocking ring 240 with the convex upper side surface enables the fixing holes to be better isolated, and liquid on the inner side cannot easily enter the fixing holes.

The outer wall of the lower portion 300 of the tube body is provided with a sealing recess 310. It can be used for connecting other drainage device, improves sealed effect.

One way of the leak-trap connector for refrigerated containers is by using TPV material. High stability, high ageing resistance and high low-temp resistance.

An inner threaded part 400 is arranged on the inner wall of the upper end of the tubular body 100; the sealing part has a good sealing effect when being connected with a water leakage device of the refrigerated container and also has good connection strength.
