Abstract
The utility model relates to a sealing component, in particular to a water-sealing element. The utility model aims at overcoming the defects of a single water-sealing device in the prior art. The sealing component of the utility model comprises an outer water-sealing device, wherein the water-sealing device comprises an outer sealing framework and an outer water-sealing sealing lip, wherein the sealing lip and a rotating shaft are in interference fit, an inner water-sealing device is arranged between the outer water-sealing framework and the rotating shaft, the inner water-sealing device comprises an inner water-sealing sealing lip and an inner water-sealing framework, a lip opening of the inner water-sealing sealing lip and the rotating shaft are in interference fit, bulges are arranged at intervals on the corresponding outer sides of the sealing body in the direction facing the outer water-sealing device, concave pits are arranged between the bulges, the bulges are rubber bodies, the rubber bodies and the outer water-sealing framework are in interference fit, the inner water-sealing framework is positioned under the outer water-sealing framework, and a gap is arranged between the inner water-sealing framework and the outer water-sealing framework. The utility model effectively prevents leaked water from flowing into bearings, prevents the rust etching and failure of the bearings, and prolongs the service life of a machine body.
Description
Technical field
The utility model relates to a kind of sealed member, especially a kind of water seal part.
Background technique
Water seal at present commonly used mostly is the monomer sealing structure for water, and as shown in Figure 1, this water seal comprises skeleton and sealing lip, and by the interference fit between the interference fit between sealing lip and the running shaft and water seal cylindrical and the casing, water seal is installed in needs sealing part.The defective that this water seal exists is that when water seal takes place to leak, the water that leaks outflow will directly flow to bearing along the direction of arrow among the figure, cause the bearing corrosion to be lost efficacy, and influence the proper functioning of washing machine.When the bearing failure place under repair, can take great amount of manpower and material resources again, improved user cost greatly.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective that existing monomer water seal exists, and has proposed a kind of combined type water seal seal ring, and it stops the water of leakage to flow in the bearing effectively, prevents that the corrosion of bearing was lost efficacy, and has prolonged the working life of body.
The utility model is to adopt following technological scheme to realize: a kind of combined type water seal seal ring, comprise outer water seal, outer water seal comprises outer water seal skeleton and outer water seal sealing lip, be interference fit between sealing lip and the running shaft, its China and foreign countries' water seal comprises outer water seal skeleton and outer water seal sealing lip, be interference fit between sealing lip and the running shaft, it is characterized in that: be provided with interior water seal between described outer water seal skeleton and the running shaft, water seal sealing lip and interior water seal skeleton in interior water seal comprises, the lip of interior water seal sealing lip and running shaft interference fit, the corresponding seal outside and the side of water seal outward are interval with projection, depression is set between the projection, and projection is a rubber body, is interference fit between rubber body and the outer water seal skeleton, interior water seal skeleton is positioned at the below of outer water seal skeleton, and is provided with the gap between two skeletons.
In the utility model, by the interference fit between water seal sealing lip in reaching between projection and the outer water seal skeleton and the running shaft, water seal can be positioned between outer water seal and the running shaft in making.When outer water seal is leaked, in water can be flowed directly in the water seal, and by interior water seal with the current that spill along the depression on the annular protrusion from outer water seal skeleton and the gap between the interior water seal skeleton flow out to water receiving pipe.Therefore water seal has changed the flow direction of current in, thereby has played the effect of protection bearing.
The beneficial effects of the utility model are: when there is leakage in outer water seal, by interior water seal is set, the water of revealing is played the effect of guiding, change the flow direction of the water of revealing, it is guided to privileged site, stoped water to flow directly into bearing, the corrosion that prevents bearing was effectively lost efficacy, prolong the working life of bearing, made the body can proper functioning, improved the working efficiency of body.

Fig. 1 is the half sectional view of water seal in the prior art;
Fig. 2 is the half sectional view of water seal in the utility model;
Fig. 3 is that K among Fig. 2 is to view;
Fig. 4 is that A-A among Fig. 3 is to sectional view.
Embodiment
As Fig. 2, Fig. 3 and shown in Figure 4, water seal is a combined type water seal ring structure, it comprises outer water seal 1 and interior water seal 3, described outer water seal 1 comprises outer water seal sealing lip and outer water seal skeleton 2, water seal sealing lip 4 and interior water seal skeleton in interior water seal 3 comprises wherein are interference fit between the lip of interior water seal sealing lip 4 and the running shaft.Be interval with projection 7 on the corresponding seal outside and the side of water seal outward, depression 9 is set between the adjacent protrusion 7, the outside of projection 7 is a rubber body, and interior water seal 3 is interference fit by rubber body and outer water seal 1, thus water seal location in making.Be provided with the gap between interior water seal skeleton 6 and the outer water seal skeleton 2, this gap provides flow pass for leaking.When outer water seal 1 takes place to leak, water seal 3 in the water of leakage flows to along the direction of arrow among the figure, and in interior water seal depression 9 flows into water seal skeleton 6 and outside between the water seal skeleton 2, and flow out in the water receiving pipe.By the sealing and the guide functions of interior water seal, the water of leakage is directed in the water receiving pipe, can the bearing 8 of its below not damaged, and has guaranteed the proper functioning of bearing 8.
