Abstract
The invention discloses a dustproof sealing ring which comprises a main oil seal. The dustproof sealing ring is characterized in that the main oil seal comprises a metal framework, an annular sealing spring and sealing rubber; the sealing rubber is arranged on the inner side of the main oil seal; one end of the sealing rubber is provided with a first sealing part used for clamping and sealing the metal framework, and the other end of the sealing rubber is provided with a second sealing part used for clamping and sealing the annular sealing spring; and the outer wall of an auxiliary oil seal is tightly clamped in the metal framework of the main oil seal. Due to the fact that the auxiliary oil seal is additionally arranged on the inner side of the main oil seal, sealing of impurities in a medium can be effectively prevented, pressure impacts in a cavity can be properly reduced, and the service life of the sealing ring is prolonged. The dustproof sealing ring is suitable for an occasion where dust prevention needs to be conducted on the two sides and oil sealing needs to be conducted in the middle. For example, the dustproof sealing ring is used for sealing water and washing preparations in a washing machine.
Description
Technical field
The present invention relates to a kind of dust-proof seal ring.
Background technology
Traditional sealing ring is only capable of playing the function of sealing, it is impossible to be suitable for some middle oil sealings and both sides need dust-proof occasion.
Summary of the invention
For the problems referred to above, the present invention provides a kind of dust-proof seal ring, it is adaptable to middle oil sealing and both sides need dust-proof occasion, simple in construction, can the suitably compression shock in abatement chamber body, the service life of raising sealing ring.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of dust-proof seal ring, including main oil sealing, it is characterized in that, described main oil sealing includes metallic framework, ring packing spring and caulking gum, external diameter rubber layer it is provided with outside described metallic framework, described caulking gum is arranged on inside main oil sealing, and one end of described caulking gum is provided with and is provided with for clamping the second sealing of sealing annular Packing spring for clamping the first sealing of sealing metal skeleton and the other end, and the outer wall of a secondary oil sealing is closely fastened in the metallic framework of main oil sealing.
Preferably, described metallic framework is iron material matter skeleton.
Preferably, described secondary oil sealing is in cylindrical groove-like.
The invention has the beneficial effects as follows:
Increase a secondary oil sealing in the inner side of main oil sealing, can effectively prevent the impurity in sealing medium, and can the suitable compression shock in abatement chamber body, improve the service life of sealing ring, it is applicable to both sides and needs the occasion of dust-proof and middle oil sealing, such as, in washing machine, seal water and laundry detergents.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of dust-proof seal ring of the present invention；
The labelling implication of accompanying drawing is as follows:
1: caulking gum；2: metallic framework；3: ring packing spring；4: secondary oil sealing；5: the second sealings；6: the first sealings；7: external diameter rubber layer.
Detailed description of the invention
Being described in further detail technical solution of the present invention with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
A kind of dust-proof seal ring, including main oil sealing, as shown in Figure 1, described main oil sealing includes metallic framework 2, ring packing spring 3(can also be the iron wire loop of annular) and caulking gum 1, it is provided with external diameter rubber layer 7 outside described metallic framework 2, described caulking gum 1 is arranged on inside main oil sealing, one end (left end in Fig. 1) of described caulking gum 1 is provided with and is provided with for clamping the second sealing 5 of sealing annular Packing spring 3 for clamping the first sealing 6 of sealing metal skeleton 2 and the other end (right-hand member in Fig. 1), the outer wall of one secondary oil sealing 4 is closely fastened in the metallic framework 2 of main oil sealing.
Caulking gum 1 has elastic nature, and countershaft have goodish sealing effectiveness, and metallic framework 2 can be iron material matter skeleton, increases rigidity and makes sealing ring to deform easily, and ring packing spring 3 provides the certain binding force of caulking gum 1 and extends the service life of sealing ring.
Secondary oil sealing 4 provides the rigidity of sealing ring and plays dust reduction capability, it is preferable that secondary oil sealing 4 is in cylindrical groove-like.Its sectional view is as it is shown in figure 1, the outer wall of described secondary oil sealing 4 is provided with anti-skid structure, and such as, anti-skid structure is anti-slip rubber layer.Wherein, described ring packing spring 3 can select iron material matter spring.
Increase a secondary oil sealing in the inner side of main oil sealing, can effectively prevent the impurity in sealing medium, and can the suitable compression shock in abatement chamber body, improve the service life of sealing ring, it is applicable to both sides and needs the occasion of dust-proof and middle oil sealing, such as, in washing machine, seal water and laundry detergents.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, is the most in like manner included in the scope of patent protection of the present invention.
