Abstract
Provided is a self-locating assembling structure of a vacuum arc-extinguishing chamber ceramic housing and a sealing ring. The self-locating assembling structure comprises a ceramic housing and a sealing ring and is characterized in that a transition ring is installed in the ceramic housing, that multiple limiting bags are disposed on the circular wall of the transition ring and lean against the inner wall of the ceramic housing, that a limiting table is disposed on the bottom of the transition ring and is arranged outside the ceramic housing, and that the sealing ring is fixedly disposed on the limiting table of the transition ring. The self-locating assembling structure has advantages of self locating, guaranteed product coaxiality, no need in grinding the port of the ceramic housing, no need in locating with a ceramic mould, easy manipulation, and reduced cost.
Description
Technical field
The utility model relates to a kind of vacuum arc-extinction porcelain shell and the self-align assembly structure of sealing ring.
Background technology
The coaxial dependence porcelain mold of existing vacuum interrupter sealing ring, porcelain shell guarantees, for realizing the tolerance fit of mould and porcelain shell, guarantees the axiality of product, and the matching part of porcelain shell, porcelain mold need to grind processing, and cost is higher.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, provide a kind of can be self-align, guarantee the axiality of product, the porcelain shell need not to grind port, need not porcelain mold location, easy to operate and vacuum arc-extinction porcelain shell and the self-align assembly structure of sealing ring that can reduce costs.
The utility model is achieved in that
The self-align assembly structure of vacuum arc-extinction porcelain shell and sealing ring, comprise porcelain shell and sealing ring, its special character is: in the porcelain shell, transition rings is installed, the round wall of transition rings is provided with a plurality of spacing bags, described spacing bag leans on porcelain shell inwall, the transition rings bottom is provided with limiting stand, and described limiting stand is positioned at outside the porcelain shell, and described sealing ring is installed on the limiting stand of transition rings.
The utility model has the advantages that:
1, the spacing porcelain shell of spacing bag, the spacing sealing ring of limiting stand, by the position-limiting action of transition rings, the relative position relation of porcelain shell and sealing ring is determined, thereby guarantees product axiality index;
2, can realize self-alignly, save the assembling mould, the porcelain shell need not to grind port, need not the porcelain mold location, and is easy to operate, improved production efficiency, reduced processing cost; Thermal capacity during welding reduces, thus energy savings, low-carbon environment-friendly.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A section enlarged drawing of Fig. 1;
In figure: 1-porcelain shell, 2-transition rings, the spacing bag of 3-, 4-sealing ring, 5-limiting stand.
Embodiment
As shown in the figure, in the interior installation transition rings 2 of porcelain shell 1, the round wall of transition rings 2 is provided with a plurality of spacing bags 3, and this example is take 4 as example.Described spacing bag 3 leans on porcelain shell 1 inwall, and transition rings 2 bottoms are provided with limiting stand 5, and described limiting stand 5 is positioned at outside porcelain shell 1, and soldering has sealing ring 4 on the limiting stand 5 of transition rings 2.
