Abstract

The utility model devises a kind of corrugated pipe sealing ring, including sealing ring ontology, sealing ring body interior designs for cylindrical hole, and limiting stand and seal section are designed on sealing ring ontology, the limiting stand internal diameter is identical as seal section outer diameter, and protrusion is designed on seal section inner ring；When corrugated pipe sealing ring is connect with bellows, sealing ring is socketed on bellows by sealing ring natural resiliency, the protrusion designed on sealing ring seal section inner ring is engaged with inner groovy on bellows, realize insert seal, this kind of structure design can effectively ensure product when long-time uses, it is not susceptible to the influence that bellows expands with heat and contract with cold, effectively ensures sealing performance, extends the service life of product；When seal section uses inclined design far from limiting stand side, relative to planar design situation, ramp structure design can be preferably embedded between bellows and connection structure, and better seal effect is realized to bellows and connection structure.

Description

Corrugated pipe sealing ring

Technical field

The utility model is related to sealing ring more particularly to a kind of corrugated pipe sealing rings.

Background technology

The sealing structure being currently used in the corrugated water pipe connection structure of house ornamentation water compared with mostly use conventional structure design Sealing ring, this kind of sealing structure face is smaller, and sealing structure is influenced to be easy out during long-time use by expanding with heat and contract with cold The case where existing seal leakage or failure.

Invention content

In order to make up deficiency in the prior art, the utility model devises a kind of bellows special sealing ring, the sealing Coil structures design is used cooperatively with bellows, can be very good the defect for making up the prior art.

To achieve the goals above, the technical solution adopted in the utility model is as follows：

Corrugated pipe sealing ring, including sealing ring ontology, sealing ring body interior design for cylindrical hole, sealing ring ontology On be designed with limiting stand and seal section, the limiting stand internal diameter is identical as seal section outer diameter.

Further, the seal section is designed with inclined-plane far from limit end, and the angle between inclined-plane and horizontal line is a, 30 ° ≤a≤80。

Preferably 60 ° of angle a.

Protrusion is designed on seal section inner ring described further, the protrusion vertical section is designed for semicircular structure, described Convex design number is n, and 1≤n≤5, the equidistant design of protrusion is on seal section inner ring.

Raised number n preferably 2.

The limiting stand outer rim is designed using arc surface, can also use planar design.

Arc chord angle transition is used between the limiting stand and seal section, can also use right angle transition.

The beneficial effects of the utility model：When the corrugated pipe sealing ring designed using the utility model is connect with bellows, Sealing ring is socketed on bellows by sealing ring natural resiliency, the protrusion and bellows designed on sealing ring seal section inner ring Upper inner groovy occlusion realizes that insert seal, this kind of structure design can effectively ensure product for a long time in use, not allowing Easily being expanded with heat and contract with cold by bellows is influenced, and effectively ensures sealing performance, extends the service life of product；When seal section is far from limit When position platform side uses inclined design, relative to planar design situation, ramp structure design can preferably be embedded in bellows and company Between binding structure, better seal effect is realized to bellows and connection structure.

Specific implementation mode

As shown in Figure 1 and 2, corrugated pipe sealing ring, including sealing ring ontology 1,1 inside of sealing ring ontology is cylindrical hole It designs, is designed with limiting stand 2 and seal section 3 on sealing ring ontology 1,2 internal diameter of the limiting stand is identical as 3 outer diameter of seal section.

Embodiment 1, as shown in figure 3, being designed with protrusion 4 on 3 inner ring of the seal section, raised 4 vertical section is semicircle Shape structure design, 4 numbers of protrusion are 2.

Embodiment 2, as shown in figure 4, the seal section 3 is designed with inclined-plane 5 far from 2 end of limiting stand, inclined-plane 5 and horizontal line it Between angle be a, angle a is using 60 ° of designs.

Embodiment 3 uses circular arc as shown in figure 5, on the basis of embodiment 1 between the limiting stand 2 and seal section 3 Angle transition.

Embodiment 4, as shown in fig. 6, on the basis of embodiment 1,2 outer rim of the limiting stand is designed using arc surface.

Embodiment 5 is designed with protrusion 4 as shown in fig. 7, in conjunction with the embodiments 1 and 2 on 3 inner ring of seal section, convex The number for playing 4 is 2, and seal section 3 is designed with inclined-plane 5 far from 2 end of limiting stand.

Embodiment 6 is designed with protrusion 4 as shown in figure 8, in conjunction with the embodiments 1 and 2 on 3 inner ring of seal section, convex The number for playing 4 is 3, and for 4 equidistant design of protrusion on 3 inner ring of seal section, seal section 3 is designed with inclined-plane 5 far from 2 end of limiting stand.

As shown in figure 9, when sealing ring is connect with bellows 7, sealing ring is socketed in by 1 natural resiliency of sealing ring ontology On bellows 7, the protrusion 4 designed on 3 inner ring of sealing ring seal section is engaged with inner groovy 8 on bellows 7, is realized embedded close Envelope.

Finally it is to be understood that, a series of above-mentioned embodiments are only more intuitively to express the utility model technical side Case, can not be any to pass through technical solutions of the utility model as the foundation for limiting the utility model claims protection domain The design for not making inventive improvements belongs to the claimed range of technical solutions of the utility model, similarly, new according to this practicality The structure design that type above-described embodiment is combined or splits also belongs to the utility model claims protection domain.
