Abstract
The invention discloses a sealing piece comprising a support ring frame and an annular sealing ring, wherein an annular groove is arranged along the inner wall surface of the support ring frame, a side rib, which is connected with the annular groove in a clamping way, is arranged in the middle of the outer side surface of the annular sealing ring, the upper end and the lower end of the annular sealing ring respectively extend out of the upper end surface and the lower end surface of the support ring frame, the support ring frame is formed by connecting an upper support ring frame and a lower support ring frame by a connecting mechanism, the upper support ring frame and the lower support ring frame are respectively provided with an upper annular groove unit and a lower annular groove unit forming the annular groove, an inner groove surfaces are arranged at the inner ends of the upper annular groove unit and the lower annular groove unit, and a bulge, corresponding to the inner groove surface, is arranged at the end part of the side rib. The sealing piece has a simple structure, is convenient to process, can be prevented from being damaged by expansion due to overlarge fastening force, and has the advantage of being convenient to install and replace.
Description
Technical field
The present invention relates to Sealing.
Background technique
In various products such as gear-box, piston, oil cylinder, sealability between its housing is to guarantee one of essential condition that product is working properly, existing structure is provided with the seal ring caulking groove usually and seal ring is installed is then sealed between housing, its deficiency is to change in the caulking groove seal ring over to relatively trouble, jumps out easily; Another common structure is the directly flat seal ring realization sealing of installation of jointing end face at housing, and Sealing by bloated bad, also occurred shift phenomenon easily, thereby influences sealability easily when its deficiency was to connect too closely.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of Sealing, and is simple in structure, easy to process, can prevent that fastening force is excessive by bloated bad, also has and installs and change advantage easily.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of Sealing, it is characterized in that: comprise that one supports a ring stand and an O-ring seal, internal face along described support ring stand is provided with annular groove, described O-ring seal outer side surface middle part is provided with the limit muscle with described annular groove clamping, the upper and lower end of O-ring seal stretches out the upper and lower end face of supporting ring stand respectively, described support ring stand is formed by connecting by bindiny mechanism by upper support ring stand and lower support ring stand, be respectively equipped with the last annular groove unit of forming annular groove on upper support ring stand and the lower support ring stand and reach annular groove unit down, described last annular groove unit and following the inner, annular groove unit are equipped with the indent groove face, and muscle end, described limit is provided with and the corresponding projection of described inner groovy face.Support ring stand and design, be convenient to the processing of inner concave arc surface, make muscle end, limit that projection conveniently is set and cooperate that O-ring seal is more firm with being connected of support ring stand with inner concave arc surface by split-type structural.
Preferably, described indent groove face is an arc shaped surface, and described projection is an arc convex.
Preferably, described bindiny mechanism comprises that uniform ring is located at least two vertical slot on the lower support ring stand outer wall, be provided with the indent draw-in groove in the vertical slot, described upper support ring stand outer wall is provided with the attachment post corresponding with described vertical slot, and attachment post is provided with and the corresponding dop of described indent draw-in groove.
Preferably, described O-ring seal is stretched out the length that supports the ring stand upper-end surface for supporting 0.2～0.6 times of ring stand thickness, and described O-ring seal is stretched out the length that supports the ring stand lower end surface for supporting 0.2～0.6 times of ring stand thickness.The sealing effect and the stability of Sealing are all guaranteed preferably.
Improved, described support ring stand outer side surface is equipped with some locating flange ears, and the locating flange ear is corresponding with fastening piece between housing, thereby Sealing is realized the location.
The present invention cooperates O-ring seal with the support ring stand; when housing is fastening; owing to support the protective action of ring stand, make seal ring can not pressed tension and expand badly, guarantee the stability of its sealing; when Sealing is installed owing to support ring stand with stable fixing of seal ring; make easier for installationly, do not worry seal ring displacement, this structure can prolong the working life of Sealing; and it is easy to process to support ring stand, and it is convenient to change seal ring.
