Abstract

The invention provides a seal assembly in a concrete drain pipe. The seal assembly in the concrete drain pipe belongs to the field of mechanical technique, and solves the problem of low stability in the prior art. According to the seal assembly in the concrete drain pipe, the concrete drain pipe comprises a long-tubular body; a concave connecting seat is arranged on the end part of the body; the seal assembly is located at the end part of the body and comprises a seal ring I and a seal ring II; the seal ring I and the seal ring II are made of flexible materials; a connecting structure for tightly connecting the seal ring I and the seal ring II is arranged between the seal ring I and the seal ring II; and when two adjacent bodies are connected in series, the seal ring I and the seal ring II are tightly pressed between the two bodies. The seal assembly in the concrete drain pipe is high in stability and good in sealing performance.

Description

Black box in concrete drain tile

Technical field

The invention belongs to field of mechanical technique, the black box being related in a kind of concrete drain tile.

Background technology

Drainpipe mainly undertakes the task of the drainings such as rainwater, sewage, farmland discharging-irrigating.Drainpipe is divided into plastic drain-pipe, mixes Solidifying soil pipe (CP) and concrete reinforced pipe (RCP).

Pipe of concrete cost is used widely than relatively low and good corrosion resistance.

But, existing mixed mud pipe needs additionally close to its junction by outside sealing device when being connected in series Envelope.And the above-mentioned place of being tightly connected exposes outside, causes its stability poor.

The content of the invention

The purpose of the present invention is the problems referred to above existed for prior art, there is provided a kind of sealing is high and compact conformation Black box in concrete drain tile.

The purpose of the present invention can be realized by following technical proposal：

A kind of black box in concrete drain tile, mixed mud drainpipe includes the body in elongated tubular, body end With recessed connecting seat, it is characterised in that this black box is located at body end, including sealing ring one and sealing ring two, The sealing ring one is flexible material and has therebetween with sealing ring two can make its close-connected attachment structure, when Above-mentioned sealing ring one and sealing ring two are pressed between two bodies when adjacent two body is connected in series.

When mixed mud pipe is connected in series, two neighboring body realizes stabilized seal by this black box.

Creative in this component to be sealed by sealing ring one and sealing ring two, its sealing is not only higher, while by Can closely connect in two sealing rings, though after stress its connection sealing not anti-reflection and increase, therefore, stability also compares It is high.

Flexible sealing ring one and sealing ring two can further improve sealing, it can also play effective damping making With.

In black box in above-mentioned concrete drain tile, described connecting seat bottom has the convex edge of protrusion, on State and there is the recessed shoulder matched with convex edge on sealing ring one, the convex edge is embedded at recessed shoulder.

Convex edge coordinates with recessed shoulder can be such that sealing ring one is hooked at experienced level Ei seat, increase both connective stabilities.

In black box in above-mentioned concrete drain tile, the outer edge of the sealing ring two has from edge to it The guiding edge of central smoothing transition, body end has and is oriented to along the guide part for matching.

Such structure can make the stable embedding sealing circle two in the end of body.

In black box in above-mentioned concrete drain tile, described is oriented to edge for the chamfering on sealing ring two.

In black box in above-mentioned concrete drain tile, described is oriented to edge for the fillet on sealing ring two.

In black box in above-mentioned concrete drain tile, described sealing ring one and sealing ring two is rubber material Material.

In black box in above-mentioned concrete drain tile, described attachment structure is close to it on sealing ring one The positioning protruded at inner port is along one, and the positioning recessed close at its inner port of sealing ring two is along two.

Positioning coordinates with positioning along one along two concave-convex surfaces, therefore, sealing ring one and sealing ring two in loading process only Even closer can link together, without loosening or coming off.

In black box in above-mentioned concrete drain tile, described positioning is contacted with positioning along one along two faces.

Such way of contact can further improve its contact stabilization.

In black box in above-mentioned concrete drain tile, also have between described sealing ring one and sealing ring two The reinforcing washer of one metal material.

Because sealing ring one and sealing ring two are flexible material, the strong of whole seal ring assembly is improved by reinforcing washer Degree, also improves accordingly its stability.

In black box in above-mentioned concrete drain tile, have on the reinforcing washer and position along one and position Along two connecting portions for matching.

Such structure can be such that reinforcing washer is positioned between sealing ring one and sealing ring two by stable.

Compared with prior art, the black box in this concrete drain tile can be formed surely due to sealing ring one with connecting seat Fixed connection, sealing ring two can be formed with an other body end and is stably connected with, therefore, this black box sealing stability is high.

Meanwhile, the reinforcing washer between sealing ring one and sealing ring two can also further improve the intensity of this component, Its stability is further improve, with very high practical value.

Specific embodiment

As shown in figure 1, the black box in this concrete drain tile, mixed mud drainpipe includes the body 1 in elongated tubular, The end of body 1 has recessed connecting seat 1a, and this black box is located at the end of body 1, including sealing ring 1 and sealing ring two 3, the sealing ring 1 is flexible material and has therebetween with sealing ring 23 can make its close-connected connection knot Structure, when adjacent two body 1 is connected in series, above-mentioned sealing ring 1 and sealing ring 23 are pressed between two bodies 1.

Described connecting seat 1a bottoms have the convex edge 1a1 of protrusion, have and convex edge 1a1 phases on above-mentioned sealing ring 1 The recessed shoulder 2a for matching somebody with somebody, the convex edge 1a1 are embedded at recessed shoulder 2a.

The outer edge of the sealing ring 23 has by the edge guiding that thereto heart is seamlessly transitted along 3a, the end of body 1 tool There is the guide part matched along 3a with guiding.

In this enforcement, described guiding is the chamfering on sealing ring 23 along 3a.According to actual conditions, described guiding edge It is also feasible for the chamfering on sealing ring two.

Described sealing ring 1 and sealing ring 23 is elastomeric material.

Described attachment structure be the positioning protruded close at its inner port on sealing ring 1 along a 2b, and sealing ring 23 recessed positioning close at its inner port are along two 3b.

Described positioning is contacted with positioning along a 2b along two 3b faces.

The also reinforcing washer 4 with a metal material between described sealing ring 1 and sealing ring 23.

There is the connecting portion matched along two 3b along a 2b and positioning with positioning on the reinforcing washer 4.
