Abstract
The invention discloses a double-layer washer. The double-layer washer comprises a first thin permanent magnet iron ring and a second thin permanent magnet iron ring, wherein a first rubber ring is arranged on the first thin permanent magnet iron ring, the lower surface of the first thin permanent magnet iron ring and the upper surface of the second thin permanent magnet iron ring are connected into a whole through a second rubber ring, and a third rubber ring is arranged under the second thin permanent magnet iron ring. According to the double-layer washer, due to the fact that the first thin permanent magnet iron ring and the second thin permanent magnet iron ring are arranged, the washer is not prone to disengagement and loss, and the use effect is good.
Description
Technical field
The present invention relates to a kind of double-deck packing ring.
Background technique
Existing packing ring easily comes off, loses.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of double-deck packing ring, difficult drop-off, loss, using effect is good.
In order to achieve the above object, the technological scheme that the present invention takes is:
A kind of double-deck packing ring, comprise the thin iron ring 1 of the first permanent magnetism and the thin iron ring 2 of the second permanent magnetism, above the thin iron ring 1 of the first permanent magnetism, dispose the first rubber ring 3, the thin iron ring 1 of the first permanent magnetism below by the linking into an integrated entity above of the second rubber ring 4 and the thin iron ring 2 of the second permanent magnetism, dispose the 3rd rubber ring 5 below the thin iron ring 2 of the second permanent magnetism.
Because the present invention is provided with the thin iron ring 1 of the first permanent magnetism and the thin iron ring 2 of the second permanent magnetism, so difficult drop-off, loss, and using effect is good.
Accompanying drawing explanation
Accompanying drawing is schematic cross-section of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
Referring to accompanying drawing, a kind of double-deck packing ring, comprise the thin iron ring 1 of the first permanent magnetism and the thin iron ring 2 of the second permanent magnetism, above the thin iron ring 1 of the first permanent magnetism, dispose the first rubber ring 3, the thin iron ring 1 of the first permanent magnetism below by the linking into an integrated entity above of the second rubber ring 4 and the thin iron ring 2 of the second permanent magnetism, dispose the 3rd rubber ring 5 below the thin iron ring 2 of the second permanent magnetism.
Because the present invention is provided with the thin iron ring 1 of the first permanent magnetism and the thin iron ring 2 of the second permanent magnetism, so difficult drop-off, loss, and using effect is good.
