The improved structure is composed of a round drum and two bowl-shaped parts with thin tubes, shapes and dimensions of the two bowl-shaped parts with thin tubes are identical, bowl-shaped parts with thin tubes are composed of cylinders, thin tubes and spherical transitional cylinders, the round drum and bowl-shaped parts with thin tubes are formed for one time through moulds respectively, and cylinders of bowl-shaped parts with thin tubes are in interference fit with end portions of the round drum.
Description
Technical field
The utility model relates to electric lighting and cermet industry, is meant a kind of TRANSLUCENT ALUMINA CERAMIC ARC TUBE improvement structure especially.
Background technology
In ceramic metal helide lamp; TRANSLUCENT ALUMINA CERAMIC ARC TUBE is one of critical piece of ceramic metal helide lamp; Aluminium oxide ceramics is with high pure alumina powder and trace mineral supplement is fired forms, and relevant TRANSLUCENT ALUMINA CERAMIC ARC TUBE mainly contains following three kinds of designs:
1, be designed to a thicker discharging chamber, long tubule is extended at the two ends of discharging chamber.
2, a kind of ceramic arc tube adopts cylindrical discharging chamber, and the annular end cap is used at the cavity two ends; Long tubule is extended along axis by annulus end cap endoporus; Its structure is made up of three bodies or five bodies, respectively the compacting or injection moulding after through the assembling, sinter holistic ceramic arc tube into.
3; A kind of aluminium oxide ceramics electric arc tube is to adopt sphere or elliposoidal discharging chamber; Long tubule is stretched out along axis by two ends, and its structure is made up of two bodies, promptly with discharging chamber center cross-sectional separated into two parts; Dock after compacting or the injection moulding respectively, sinter a bulk ceramics electric arc tube into.
Procedure in all above designs is complicated, and rate of finished products is low, is difficult to guarantee the air-tightness in the electric arc tube.
The utility model content
The purpose of the utility model provides a kind of simple in structure, the TRANSLUCENT ALUMINA CERAMIC ARC TUBE that air-tightness is high.
The utility model is realized through following technical scheme:
A kind of TRANSLUCENT ALUMINA CERAMIC ARC TUBE is improved structure; Bowl by circular cylinder and two band tubules constitutes; The bowl geomery of two band tubules is identical, and the bowl of band tubule is by cylinder, and tubule and spherical transition cylinder are formed; Described circular cylinder is used the mould one-shot forming respectively with the bowl of band tubule, and the cylinder of the bowl of band tubule is with the end interference fit of circular cylinder.
The external diameter of the cylinder of the bowl of two band tubules is identical with the external diameter of circular cylinder.
The tubule and the spherical transitional cylinder of the bowl of two band tubules are connected with circular arc.
The beneficial effect of the utility model is:
The manufacturing process of this translucent alumina ceramics pipe is simple, and helps the reliability of ceramic arc tube sintering sealing.

Embodiment
Below in conjunction with the concrete technical scheme of accompanying drawing detailed description the utility model, the specific embodiment of the utility model only is exemplary, can only be used to explain the utility model and can not be interpreted as to be the restriction to the utility model.
A kind of TRANSLUCENT ALUMINA CERAMIC ARC TUBE is improved structure, adds corresponding additive by the high-purity mangesium oxide aluminium powder and processes, and each chemical composition of aluminium oxide ceramics is not in the application's limited field; Bowl (12,13) by circular cylinder 11 and two band tubules constitutes, and the bowl geomery of two band tubules is identical; The bowl of band tubule is by cylinder (14,15), tubule (16; 17) and spherical transition cylinder (18; 19) form, described circular cylinder is used the mould one-shot forming respectively with the bowl of band tubule, and the cylinder of the bowl of band tubule is with the end interference fit of circular cylinder.
The external diameter of the cylinder of the bowl of two band tubules is identical with the external diameter of circular cylinder.
The tubule and the spherical transitional cylinder of the bowl of two band tubules are connected with circular arc.
The above only is the specific descriptions to the utility model technical scheme, and those skilled in the art can improve according to the present technique scheme certainly, and these improvement should be considered in the protection range of the utility model.
