Abstract
The utility model relates to a spring sealed structure, which comprises a camshaft, a cover, an O-shaped sealing ring which is arranged between the camshaft and a cover. A second rectangle sealing ring is arranged on top or bottom of the O-shaped sealing ring, and at least a triangle ring groove is arranged on inner or outer of the second rectangle sealing ring. Pluralities of sealing beads are formed between the sealing ring and the camshaft. A circle flange is arranged on the camshaft around the cover, and a rectangle dust-proof rubber ring is arranged between the flange and the camshaft. A triangle ring groove is arranged on inner of a dustproof rubber ring. The sealing effect is improved because a sealing ring is arranged between the camshaft and the cover. Meanwhile, another sealing ring compensates for the defacement and unfilled corner of the sealing rubber ring which are caused by friction, and the bi-sealing is achieved. The production service life which is affected by oil-lacking is prevented.
Description
Technical field
The utility model relates to a kind of door part, relates to a kind of floor spring hermetically-sealed construction particularly.
Background technology
Existing floor spring hermetically-sealed construction generally is between camshaft and the floor spring loam cake and between loam cake and the lower cover sealing ring to be set, wherein between camshaft and floor spring loam cake, use O RunddichtringO together, the phenomenon of leakage of oil in use often appears in this floor spring, its reason is when floor spring is worked and camshaft produces friction, cause ring wear between the two, and dust enter the generation that more aggravates this situation between the two.
The utility model content
The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, seals reliably, avoids leakage of oil, thereby can effectively prolong the product floor spring hermetically-sealed construction in application life.
For achieving the above object, the technical solution of the utility model is: a kind of floor spring hermetically-sealed construction, comprise camshaft, loam cake and be arranged at camshaft and loam cake between the O RunddichtringO, also be provided with the second road sealing ring at described O RunddichtringO upside or downside.
The described second road sealing ring cross sectional shape is a rectangle, is provided with at least one triangle annular groove in the inboard and/or the outside of rectangular seal, and is multiple-sealed to form between sealing ring and camshaft.
In an embodiment of this product, respectively be provided with a triangle annular groove, the sealing of enhanced leaktightness circle and camshaft and loam cake at the inboard and the outer surface of rectangular seal.
In another embodiment of this product, respectively be provided with two triangle annular grooves at the inboard and the outer surface of rectangular seal.
The described second road sealing ring can be y-type seal ring, also can be sealing ring such as O RunddichtringO, V-shaped seal ring and labyrinth sealing or the like of other kinds.
Exterior surface is provided with collar flange around described camshaft on described, is provided with dustproof cushion rubber between this flange and camshaft, prevents that dust from entering in the floor spring, effectively prevents ring wear, prolongs floor spring application life.Described dustproof cushion rubber cross section is a rectangle, is provided with the triangle annular groove one at the inner surface of dustproof cushion rubber, can play better dustproof effect.
Because oil adds sealing ring together between camshaft and loam cake, has increased sealing effectiveness, another sealing ring plays again and remedies O-ring seal because of wearing and tearing and unfilled corner that friction causes simultaneously, plays the double containment effect, prevents that product from influencing the life-span because of oil starvation.
