Abstract
The invention discloses a novel 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, 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, and the a plurality of flange ears are arranged at the outer side surface of the support ring frame in a surrounding way. For the sealing piece, the annular sealing ring is matched with the support ring frame, and when a shell is fastened, due to the protection function of the support ring frame, the sealing ring can be prevented from being damaged by expansion as being pressed tightly, therefore, the sealing stability of the sealing piece is ensured; in installing the sealing piece, as the sealing ring is fixed by the support ring frame, the installation can be more convenient, and the sealing ring can not shift; and with the structure, the service life of the sealing piece can be prolonged, and the sealing piece is convenient to 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 new type sealing element, and is simple in structure, 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 new type sealing element, 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, and the upper and lower end of O-ring seal stretches out the upper and lower end face of supporting ring stand respectively.
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.
Improved, described annular groove is a groove, and the support ring stand bottom of the support ring stand top of annular groove top and annular groove below is by the one-body molded connection of some cylinders, and described limit muscle is provided with the C shape catching groove that fastens with described cylinder.Make more stable being positioned at of O-ring seal support on the ring stand.
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 and seal ring fixed; make easier for installation; do not worry the seal ring displacement, this structure can prolong the working life of Sealing, and it is convenient to change seal ring.
