Abstract
The utility model provides a whole sealed piston ring used for the technical field of mechanical engineering, and is characterized in that a section of platform is arranged on a half part on one end of the notch of a piston ring. A sealing wall is arranged on the inner side of the platform. A sealing column is arranged on the corresponding position of the other end of the notch and the platform. A space with an equivalent thickness with the sealing wall is reserved in the inner side of the sealing column. Compared with the existing piston ring, the utility model has the advantages of good sealing effect, integral installation, convenient operation, etc.
Description
The utility model belongs to mechanical engineering technical field, is a kind of piston ring that seals entirely.
The existing piston ring, as the patent ZL94221161.8 that " seals piston ring ", the applying date 940906, its technological scheme is to offer seal groove respectively in two cut ends of piston ring, establishes a sealing block in two seal grooves altogether.It mainly is adapted to the transformation to old-fashioned piston ring.There are two major defects in it: the one, need to be equipped with in addition sealing block, poor stability during running; The 2nd, inconvenience when installing.
The purpose of this utility model be a kind of integral type of design easy to install seal piston ring entirely.
Technical solution adopted in the utility model is improved on original basis of sealing piston ring, end-grain cutting mouth half one at piston ring offers one section platform, radially leave certain thickness ring body as envelope wall along platform inboard, ring body, install sealing column at corresponding half position of the other end otch of piston ring, the inboard of sealing column is given and being kept with the suitable space of envelope wall thickness, thereby constitutes a kind of piston ring that seals entirely.
Because the utility model has been taked technique scheme, compares with existing piston ring, have one and install, easy to use, remarkable advantages such as good sealing effect.
Below in conjunction with accompanying drawing and example specific structural features of the present utility model is described further.
Accompanying drawing is represented cutting part schematic representation of the present utility model.
As shown in the figure, the utlity model has piston ring ring body 1, ring body 1 has two cut ends, and the first half of an end or Lower Half offer place's platform 2 along the circle edge direction therein.Along the inboard of platform 2, ring body radially leave certain thickness ring body as envelope wall 3, the first half or Lower Half at the other end of otch are provided with a sealing column 4 with platform 2 corresponding positions, the body of sealing column 4 is suitable with the space of platform 2.On the inboard ring body of sealing column 4, be reserved with the suitable space of envelope wall 3 thickness.Sealing column 4 is nested in the platform 2 during use.
In order to seal more perfectly, envelope wall 3 can extend along peripheral direction, simultaneously, gives in the inboard of another cut ends and to reserve the space that holds envelope wall 3, thereby realize sealing entirely.
