Abstract
The utility model discloses 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, described caulking gum is arranged on inside main oil sealing, 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.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.
Description
Technical field
This utility model 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 field
Close.
Utility model content
For the problems referred to above, this utility model provides a kind of dust-proof seal ring, it is adaptable to middle oil sealing and both sides need anti-
The occasion of dirt, simple in construction, can the suitable compression shock in abatement chamber body, improve the service life of sealing ring.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions:
A kind of dust-proof seal ring, including main oil sealing, it is characterised in that described main oil sealing includes metallic framework, ring packing
Spring and caulking gum, be provided with external diameter rubber layer outside described metallic framework, described caulking gum is arranged on inside main oil sealing,
One end of described caulking gum be provided with for clamping the first sealing of sealing metal skeleton and the other end be provided with for
Clamping and seal the second sealing of annular Packing spring, the outer wall of a secondary oil sealing is closely fastened on the metallic framework of main oil sealing
In.
Preferably, described metallic framework is iron material matter skeleton.
Preferably, described secondary oil sealing is in cylindrical groove-like.
The beneficial effects of the utility model are:
Increase a secondary oil sealing in the inner side of main oil sealing, can effectively prevent the impurity in sealing medium, and can suitably cut down
Compression shock in cavity, improves the service life of sealing ring, it is adaptable to both sides need the occasion of dust-proof and middle oil sealing, than
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 this utility model；
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；Seal at 6: the first
Portion；7: external diameter rubber layer.
Detailed description of the invention
With specific embodiment, technical solutions of the utility model are described in further detail below in conjunction with the accompanying drawings, so that
Those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to this reality
With novel restriction.
A kind of dust-proof seal ring, including main oil sealing, as it is 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, institute outside described metallic framework 2
Stating caulking gum 1 and be arranged on inside main oil sealing, one end (left end in Fig. 1) of described caulking gum 1 is provided with for clamping also
First sealing 6 of sealing metal skeleton 2 and the other end (right-hand member in Fig. 1) are provided with for clamping and seal ring packing bullet
Second sealing 5 of spring 3, the outer wall of a 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 bone
Frame, 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 close
The service life of seal.
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.Its
In, 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 suitably cut down
Compression shock in cavity, improves the service life of sealing ring, it is adaptable to both sides need the occasion of dust-proof and middle oil sealing, than
As, in washing machine, seal water and laundry detergents.
These are only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize equivalent structure or equivalence flow process conversion that this utility model description and accompanying drawing content made, or directly or indirectly transport
It is used in other relevant technical fields, is the most in like manner included in scope of patent protection of the present utility model.
