Abstract
The utility model discloses a novel dustproof ring, which comprises an annular ring, wherein a circle of inwards extending outer dustproof lip is arranged on the upper periphery of the annular ring, a circular of inwards extending inner sealing lip is arranged on the lower periphery of the annular ring, and at least one circle of inwards extending middle lip is arranged on the inner side wall of the annular ring arranged between the outer dustproof lip and the inner sealing lip. The novel dustproof ring has the advantages that the stability of the dustproof ring is greatly improved, the lip opening turning is effectively prevented, and the service life of the dustproof ring is prolonged; in addition, the dustproof effect of the dustproof ring is enhanced, the seepage of medium oil in an oil cylinder is effectively prevented, and the generation of oil stain is avoided. In addition, the novel dustproof ring is an element capable of realizing common use with the existing single-lip dustproof ring or double-lip dustproof ring, and the dimension of a groove for installing the dustproof ring does not need to be changed, so high practicability and great convenience are achieved.
Description
Technical field
The utility model relates to a kind of Sealing, is specifically related to a kind of structure improved Dustproof circle.
Background technique
The cylinder system of straight reciprocating motion need to assemble a dust ring and prevent that the systems of entering such as extraneous impurity, dust, moisture from destroying cylinder system and sealing system.Existing conventional dust ring is as two lip dust rings, its structure as shown in Figure 1 and Figure 2: dust ring comprises an annular ring 1, and the upper periphery of annular ring is provided with the outer dust excluder lips 2 that a circle extends internally, and following peripheral is provided with the interior sealing lip 3 that a circle extends internally simultaneously.The dust ring of this kind of structure can effectively prevent oozing out of the interior medium oil film of oil cylinder, avoids the generation of greasy dirt.But in straight reciprocating motion, outer dust excluder lips 2 and interior sealing lip 3 easily overturn, outer dust excluder lips 2 is outwards overturn, and can cause extraneous dust to invade, and interior sealing lip 3 upsets easily cause oil film to ooze out, thereby cause cylinder system to pollute, the life-span of greatly reducing dust ring.
Model utility content
The purpose of this utility model is to provide a kind of structure improved Dustproof circle, to solve the deficiencies in the prior art part.
For achieving the above object, the utility model adopts following technological scheme:
Dustproof circle, has an annular ring, and the upper periphery of annular ring is provided with the outer dust excluder lips that a circle extends internally, and the following peripheral of annular ring is provided with the interior sealing lip that a circle extends internally; Annular ring madial wall between described outer dust excluder lips and interior sealing lip is provided with the middle interlabium that at least one circle extends internally.
As preferably, the quantity of described middle interlabium is a circle.
As a kind of selection, described outer dust excluder lips slopes inwardly to extend and arranges.
As another kind, select the setting that radially extends internally of described outer dust excluder lips.
As a kind of selection, described interior sealing lip slopes inwardly to extend and arranges.
As another kind, select the cross section indentation of described interior sealing lip.
As a kind of selection, the setting that radially extends internally of described middle interlabium.
As another kind, select the cross section indentation of described middle interlabium.
The utility model, by adopting said structure, has improved the stability of dust ring greatly, has effectively prevented lip upset, has improved the dust ring life-span; And strengthened the dust-proof effect of dust ring, effectively prevented oozing out of the interior Medium Oil of oil cylinder, avoided the generation of greasy dirt.Also have, the utility model and used single lip dust ring or two lip dust rings be can be general element, need not change the groove dimensions that dust ring is installed, so very practical, facilitate.

In figure:
1-annular ring; 2-outer dust excluder lips; 3-interior sealing lip; 4-middle interlabium.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.
Embodiment
Embodiment 1
As shown in Figure 3, Dustproof circle described in the utility model, has an annular ring 1, and the upper periphery of this annular ring 1 is provided with the outer dust excluder lips 2 that a circle slopes inwardly and extends; The following peripheral of annular ring 1 is provided with the interior sealing lip 3 that a circle slopes inwardly and extends; Annular ring 1 madial wall between described outer dust excluder lips 2 and interior sealing lip 3 is provided with the middle interlabium 4 that a circle radially extends internally.
During the utility model work, outer dust excluder lips 2 mainly plays and prevents extraneous dust invasion cylinder system; Interior sealing lip 3 mainly plays and prevents oozing out of the interior medium oil film of oil cylinder; And middle interlabium 4 plays the effect of auxiliary stable outer dust excluder lips and interior sealing lip, prevent outer dust excluder lips 2 and 3 upsets of interior sealing lip.
Embodiment 2
As shown in Figure 3, Dustproof circle described in the utility model, has an annular ring 1, and the upper periphery of this annular ring 1 is provided with the outer dust excluder lips 2 that a circle radially extends internally; The following peripheral of annular ring 1 is provided with the interior sealing lip 3 that a circle slopes inwardly and extends; Annular ring 1 madial wall between described outer dust excluder lips 2 and interior sealing lip 3 is provided with the middle interlabium 4 that a circle slopes inwardly and extends.Wherein, the equal indentation of cross section of interior sealing lip 3 and middle interlabium 4.
During the utility model work, outer dust excluder lips 2 mainly plays and prevents extraneous dust invasion cylinder system; Interior sealing lip 3 mainly plays and prevents oozing out of the interior medium oil film of oil cylinder; And middle interlabium 4 plays the effect of auxiliary stable outer dust excluder lips and interior sealing lip, prevent outer dust excluder lips 2 and 3 upsets of interior sealing lip.
