Abstract
The invention discloses a kind of dust ring, includes dust ring body；The dust ring body is annular shape in uniform thickness, and upper and lower ends are respectively equipped with the first annulus, the second annulus；First annulus and the second annulus are connected by cylinder；The through hole run through is provided with the middle part of the dust ring body；Dust ring of the present invention can be arranged on circular indentation, there, both filled up breach, also played dustproof effect.
Description
Technical field
The present invention relates to a kind of improvement of dust ring, more particularly to a kind of installed in the dust-proof of circular indentation, there
Circle.
Background technology
At present for the sealing at breach, gap all be using strip gasket bar be close to post breach, gap profile side
Formula, the strip gasket bar in such a sealing means easily drop.
The content of the invention
There is provided the invention aims to overcome the deficiencies in the prior art a kind of installed in the anti-of circular indentation, there
Konisphere.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of dust ring is provided；Include dust ring body；
The dust ring body is annular shape in uniform thickness, and upper and lower ends are respectively equipped with the first annulus, the second annulus；First circle
Ring and the second annulus are connected by cylinder；The through hole run through is provided with the middle part of the dust ring body.
Preferably, the external diameter of first annulus is slightly larger than the external diameter of the second annulus, and the annular shape that may be stuck in install lacks
Above mouthful, avoid dropping.
Preferably, the material of the dust ring is rubber.
Advantage：Dust ring of the present invention is hollow circular ring-shaped member, and material is rubber, can be arranged on circular breach
Place, has both filled up breach, has also played dustproof effect.
Brief description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings：
Accompanying drawing 1 is the front view of dust ring of the present invention;
Accompanying drawing 2 is the stereogram of dust ring of the present invention;
Wherein：1st, the first annulus；2nd, the second annulus；3rd, through hole.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
Accompanying drawing 1-2 is a kind of dust ring of the present invention；Include dust ring body；The dust ring body is that thickness is equal
Even annular shape, upper and lower ends are respectively equipped with the first annulus 1, the second annulus 2；The annulus 2 of first annulus 1 and second passes through circle
Post connects；The through hole 3 run through is provided with the middle part of the dust ring body；The external diameter of first annulus 1 is slightly larger than the second annulus 2
External diameter, it may be stuck in above the circular breach that need to be installed, avoid dropping；The material of the dust ring body is rubber, and quality is soft,
Convenient installation.
In use, only the middle part of dust ring need to be passed through into circular breach, the first annulus 1 and the second annulus 2 is set to be stuck in circle
The both sides of ring-type breach.
Dust ring of the present invention is hollow circular ring-shaped member, and material is rubber, can be arranged on circular indentation, there, both
Breach has been filled up, has also played dustproof effect.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, it should all cover within the scope of the present invention.
