Abstract
The utility model discloses an amalgam core column, which comprises a horn-shaped core column, a tubular air exhaust rod and amalgam, wherein one end of the air exhaust rod is connected with an inner wall adjacent to the bottom on the core column; the other end of the air exhaust rod is closed. The amalgam is arranged in an inner cavity of the air exhaust rod; at least one curving air extraction passage is arranged on the core column wall adjacent to the bottom of the core column; the curving air extraction passage is provided with an air extraction opening. The inner cavity of the air exhaust rod is communicated with the curving air extraction passage which is in a gradually contractible shape; thus, the section of the curving air extraction passage, which is adjacent to the air extraction opening, is less than the section adjacent to the communicating part of the air exhaust rod. The section of the air extraction passage adjacent to the air extraction opening is properly decreased, and consequently the utility model can automatically prevent the amalgam from dropping out of the core column.
Description
Technical field
The utility model relates to the electric light source technology field, and especially a kind of amalgam that can prevent directly falls the Amalgam core column that outside the stem stem.
Background technology
Mercury amalgam energy-saving tube the earliest is directly amalgam to be placed in the power saving fluorescent lamps, because amalgam and tube inner wall grazing in the fluorescent tube make fluorescent tube produce the shedding phenomenon easily, thereby influences the quality of fluorescent tube.At present the production of amalgam fluorescent tube is that amalgam is placed in the stem stem, promptly puts into a tiny glass bar by manual operation in the air exhaust rod and withstands amalgam, prevents that amalgam from directly falling outside the stem stem.In addition, on September 22nd, 1999 publication number be the CN1229521A communique and on April 16th, 2003 publication number to be that the CN2545703Y communique is described all adopt the opening on tubule have the narrow and small technical scheme of inside line of amalgam to prevent that amalgam from directly dropping in the fluorescent tube tube chamber than enclosing, such organization plan and manufacture craft, can not satisfy the production needs of automation, not only waste time and energy, and production cost is higher.
Summary of the invention
At above-mentioned deficiency, the utility model intends providing a kind of amalgam that can prevent directly to fall the Amalgam core column that outside the stem stem.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Amalgam core column, comprise horn-like stem stem, tubulose air exhaust rod and amalgam, inwall near the bottom on one end of described air exhaust rod and the described stem stem is connected, the other end sealing of described air exhaust rod, described air exhaust rod inner chamber is provided with amalgam, stem stem wall near described stem stem bottom is provided with at least one crooked bleed-off passage, the bleed-off passage of described bending has a bleeding point, described air exhaust rod inner chamber is communicated with the bleed-off passage of described bending, the bleed-off passage that it is characterized in that described bending is the shape of progressively dwindling, and the cross section of close bleeding point is less than the cross section near air exhaust rod connection place; The bleed-off passage of described bending is crooked bandlet shape passage, and described bleeding point is ellipticity.
The beneficial effects of the utility model are: by changing the shape of crooked bleed-off passage, the cross section that makes it close bleeding point is less than the cross section near air exhaust rod connection place, suitably reduce the bleed-off passage cross section near the bleeding point place, can prevent from automatically therefore that amalgam from falling outside the stem stem.In addition, this technical scheme need not increase on the stem stem of prior art or change material, so just can satisfy the production needs of automation, reduces cost thereby reach, and improves the purpose of quality and production efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation (no seal wire) of the utility model embodiment one.
Fig. 2 is the structural representation (seal wire is arranged) of the utility model embodiment two.
Among the figure, 1, stem stem, the bottom of 1-1, stem stem, 1-2, crooked bleed-off passage, 1-3, bleeding point, 2, air exhaust rod, an end that is connected near the inwall of bottom on 2-1, air exhaust rod and the stem stem, the end that 2-2, air exhaust rod are sealed, 2-3, air exhaust rod inner chamber, 3, amalgam, 4, seal wire.
Embodiment
Embodiment one as shown in Figure 1, a kind of Amalgam core column, comprise horn-like stem stem 1, tubulose air exhaust rod 2 and amalgam 3, described stem stem 1 inside is empty, one end 2-1 of described air exhaust rod 2 stretches into that stem stem 1 is inner to be connected with the inwall of close bottom 1-1 on the described stem stem 1, the other end 2-2 sealing of described air exhaust rod 2, described air exhaust rod 2 inner chamber 2-3 are provided with amalgam 3, stem stem 1 wall near described stem stem 1 bottom 1-1 is provided with at least one crooked bleed-off passage 1-2, the bleed-off passage 1-2 of described bending has a bleeding point 1-3, described air exhaust rod 2 inner chamber 2-3 are communicated with the bleed-off passage 1-2 of described bending, the bleed-off passage 1-2 of described bending makes it to be the shape of progressively dwindling by special process processing, promptly the cross section of close bleeding point 1-3 is less than the cross section near air exhaust rod 2 connections place, the bleed-off passage 1-2 of described bending is crooked bandlet shape passage, accordingly, described bleeding point 1-3 is ellipticity.Like this,, amalgam 3 is obstructed falling this section, thereby preventing that amalgam 3 from falling outside the stem stem 1 by reducing the bleed-off passage 1-2 cross section near the bleeding point place.
Embodiment two as shown in Figure 2, a kind of Amalgam core column then has seal wire 4, is used for installing electrodes, and the other technologies scheme is identical with embodiment one, no longer is repeated in this description here.
What more than enumerate only is most preferred embodiment of the present utility model, according to technique scheme those of ordinary skill all deformation programs of being not difficult directly to derive or associate, all should think protection range of the present utility model.
Claims (2)
1, a kind of Amalgam core column, comprise horn-like stem stem (1), tubulose air exhaust rod (2) and amalgam (3), one end (2-1) of described air exhaust rod (2) is connected with the inwall that described stem stem (1) is gone up near bottom (1-1), the other end (2-2) sealing of described air exhaust rod (2), described air exhaust rod (2) inner chamber (2-3) is provided with amalgam (3), stem stem (1) wall near described stem stem (1) bottom (1-1) is provided with at least one crooked bleed-off passage (1-2), the bleed-off passage of described bending (1-2) has a bleeding point (1-3), described air exhaust rod (2) inner chamber (2-3) is communicated with the bleed-off passage (1-2) of described bending, the bleed-off passage (1-2) that it is characterized in that described bending is the shape of progressively dwindling, and the cross section of close bleeding point (1-3) is less than the cross section near air exhaust rod (2) connection place.
2, Amalgam core column according to claim 1 is characterized in that the bleed-off passage (1-2) of described bending is crooked bandlet shape passage, and described bleeding point (1-3) is ellipticity.
