Abstract
The utility model discloses a multi-purpose oil seal with a corrugated framework. The multi-purpose oil seal comprises the framework and a rubber sealing body. The section of the framework is in the shape of L as a whole, the vertical section and the horizontal section of the framework are corrugated, the framework and the rubber sealing body are integrated in a vulcanization mode, a groove is formed in the position, on the top of the vertical section of the framework, of the rubber sealing body, a sealing lip is arranged in the rubber sealing body, a positioning boss is arranged outside the lower end of the rubber sealing body in an inclined mode, a protrusion extends outwards of the outer sides of the positioning boss, and the shape of the groove corresponds to that of the protrusion. The corrugated shape of the framework aims to increase the elasticity of the oil seal in the horizontal and vertical directions, and reduce abrasion of a spindle and the like; due to the design of the protrusion and the groove corresponding to the protrusion, assembling of two oil seals is facilitated; the oil seal is convenient to use and is not damaged easily.
Description
Technical field
The utility model relates generally to the Sealing field, relates in particular to a kind of multiplex oil sealing with corrugated skeleton.
Background technique
Improve sealing reliability or more severe in external environment at needs, needing to strengthen, in the situation of dust-proof effect, can increase an oil sealing usually, assembles two oil sealings to reach needed sealing effect or dust-proof effect simultaneously.Assembling two oil sealings should need to carry out twice assembling, but when actual state is assembling, normally two stacked disposable holes that are pressed into of oil sealing.Because two oil sealings are just simply stacked, while being pressed into, if just put not or run-off the straight in process of press in, dislocation occurs between oil sealing and easily causes oil sealing to be crushed out of shape, cause oil sealing to damage.
The model utility content
The utility model purpose is exactly in order to make up the defect of prior art, and a kind of multiplex oil sealing with corrugated skeleton is provided.
The utility model is achieved through the following technical solutions:
A kind of multiplex oil sealing with corrugated skeleton, include skeleton, rubbery sealed body, it is characterized in that: the cross section integral body of described skeleton is L-type, vertical section and the horizontal segment of skeleton are corrugated, skeleton and rubbery sealed body sulfuration are integrated, the rubbery sealed body inboard at the top of the vertical section of skeleton is provided with groove, the inboard of rubbery sealed body is provided with sealing lip, the outside, lower end of rubbery sealed body tilts to be provided with positioning boss, the lateral extension of positioning boss is provided with projection, and the shape of described groove is corresponding with convex shape.
Described a kind of multiplex oil sealing with corrugated skeleton, it is characterized in that: described projection, groove are respectively annular protrusion, annular groove.
The utility model has the advantages that:
It is in order to increase the elasticity of oil sealing at level and vertical direction that the utility model skeleton is provided with corrugated, makes main shaft etc. reduce wear, and is provided with the assembling that corresponding projection and groove facilitate two oil sealings, easy to use, not fragile.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of multiplex oil sealing with corrugated skeleton, include skeleton 1, rubbery sealed body 2, the cross section integral body of skeleton 1 is L-type, vertical section and the horizontal segment of skeleton 1 are corrugated, skeleton 1 is integrated with rubbery sealed body 2 sulfurations, rubbery sealed body 2 inboards at the top of the vertical section of skeleton 1 are provided with groove 5, the inboard of rubbery sealed body 2 is provided with sealing lip 4, the outside, lower end of rubbery sealed body 2 tilts to be provided with positioning boss 6, the lateral extension of positioning boss 6 is provided with projection 3, and the shape of described groove 5 is corresponding with protruding 3 shapes.
