Abstract

The utility model relates to an amalgam core column with a groove, comprising a trumpet-shaped core column, an exhaust pipe and an amalgam, wherein the profile of the core column is a trumpet shape becoming smaller from the upper side to the lower side; one end of the exhaust pipe extends to the inner of the core column and is in connection with inner walls on the core column close to the bottom, and the other end extends beyond the upper part of the core column; at least one blow aperture is provided on the core column walls close to the core column bottom; the exhaust pipe core space is communicated with the at least one blow aperture; an inner concave recessed point is provided on an exhaust pipe between the lower side of a core column trumpet mouth and the blow aperture; the amalgam is arranged above the recessed point; a groove is provided below the blow aperture. The inner concave recessed point is provided on the exhaust pipe and accordingly the internal diameter of the exhaust pipe at the position is reduced, which can prevent the amalgam in the exhaust pipe from directly falling; while argon is blown into light pipes in an exhaust process, the phosphor in pipe inner walls can be prevented from being blown caused by great pressure, and the light pipe quality can be raised.

Description

A kind of solid mercury stem stem that has groove

Technical field:

The utility model relates to the electric light source technology field, relates in particular to a kind of solid mercury stem stem that has groove.

Background technology:

Solid hydrargyrum energy-saving lamp pipe the earliest is directly will consolidate mercury to place in the power saving fluorescent lamps, because solid mercury and tube inner wall grazing in the fluorescent tube make fluorescent tube produce the shedding phenomenon easily, thereby influences the quality of fluorescent tube; The production of present solid hydrargyrum energy-saving lamp pipe is through manual, and supporting solid mercury stem stem is so a kind of device: the solid mercury of dress in blast pipe.During actual production, directly fall into the bottom in order to prevent solid mercury, the operative employee puts into a tiny glass bar from the blast pipe open end to the inside of blast pipe, relies on glass to withstand solid mercury, prevents that solid mercury from falling.The solid mercury stem stem of this kind structure, the automated production requirement of incompatibility power saving fluorescent lamps, and waste time and energy, increased production cost virtually.And when deairing step charged into argon gas in fluorescent tube, pressure was crossed conference the fluorescent material of tube inner wall is blown off, and influences the quality of fluorescent tube.

The utility model content:

The purpose of the utility model provides a kind of solid mercury stem stem that has groove, can prevent that when charging into argon gas the fluorescent material of crossing senior general's tube inner wall because of pressure blows off.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

A kind of solid mercury stem stem that has groove comprises horn-like stem stem, blast pipe and solid mercury, wherein; Big up and small down horn-like of the profile of said stem stem; One end of said blast pipe stretch into stem stem inner with said stem stem on be connected near the inwall of bottom, the other end extends the top of stem stem, is provided with at least one near the stem stem wall bottom the said stem stem and blows the hole; The inner chamber of said blast pipe is communicated with the said hole of blowing; Below the stem stem horn mouth and blow the concave point that the blast pipe of position between the hole is provided with an indent, said solid mercury is arranged on the top of said concave point, said blow the hole below also be provided with a groove.

The beneficial effect of the utility model is: because blast pipe is provided with the concave point of an indent, reduced the internal diameter of the blast pipe here, can prevent that therefore the solid mercury in the blast pipe from directly falling; And this technical scheme need not increase or change material on the stem stem of prior art; The needs of automated production have been satisfied; Enhance productivity, reduced production cost, when deairing step is blown into argon gas in fluorescent tube; Prevent that pressure from crossing the fluorescent material of senior general's tube inner wall and blowing off, improved the quality of fluorescent tube.

Embodiment

The utility model further describes below in conjunction with instance and with reference to accompanying drawing:

As depicted in figs. 1 and 2, a kind of solid mercury stem stem that has groove comprises horn-like stem stem 1, blast pipe 2 and solid mercury 3, big up and small down horn-like of the profile of said stem stem 1, and stem stem 1 inside is empty; One end 2-1 of said blast pipe 2 stretch into stem stem inner with said stem stem 1 on be connected near the inwall of bottom 1-1; The other end 2-2 of said blast pipe 2 extends the top of stem stem 1; Be provided with at least one near the stem stem wall of said stem stem 1 bottom 1-1 and blow hole 5, the inner chamber 2-3 of said blast pipe 2 is communicated with the said hole 5 of blowing, below stem stem 1 horn mouth and the blast pipe 2 that blows position between the hole 5 be provided with the concave point 4 of an indent; Said solid mercury 3 is arranged on the top of concave point 4; Owing to be provided with concave point 4, reduced the internal diameter of the blast pipe 2 here, can prevent that therefore the solid mercury in the blast pipe from directly falling; Blow hole 5 below also be provided with a groove 6, when when deairing step is blown into argon gas in fluorescent tube, prevent that pressure from crossing the fluorescent material of senior general's tube inner wall and blowing off.

The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a utility model or akin technical scheme, all within its protection range.

Claims

1. solid mercury stem stem that has groove; Comprise horn-like stem stem, blast pipe and solid mercury, big up and small down horn-like of the profile of said stem stem, an end of said blast pipe stretch into stem stem inner with said stem stem on be connected near the inwall of bottom; The other end extends the top of stem stem; Be provided with at least one near the stem stem wall of said stem stem bottom and blow the hole, the inner chamber of said blast pipe is communicated with the said hole of blowing, below the stem stem horn mouth and blow the concave point that the blast pipe of position between the hole is provided with an indent; Said solid mercury is arranged on the top of said concave point, it is characterized in that: said blow the hole below also be provided with a groove.
