Description

Mercury gun with double exhaust stroke

[affiliated technical field]

The present invention relates to the electricity-saving lamp manufacturing machine, particularly a kind of mercury gun with double exhaust stroke that is used on the round exhaust machine.

[background technology]

Round exhaust machine is a kind of common lighting production equipment, be installed in the processing tasks that mercury rifle on the round exhaust machine is mainly being born exhaust, dripped mercury, add man-hour earlier with burning one that seals in two glass rods, docking another root glass rod with the mercury rifle then vacuumizes earlier and drips last baked wheaten cake of mercury then and seal, fall into fluorescent tube for avoiding the glass rod internal diameter to cross ambassador's mercury, the exhaust glass rod internal diameter of external amalgam is less usually on the fluorescent tube.Glass rod was blocked substantially after quick rotation added and drips mercury during round exhaust machine work, the pumpdown time of mercury rifle real work is very short, and the poor effect that vacuumizes that these all cause single air exhaust rod mercury rifle influences the fluorescent tube quality, reduce the fluorescent tube product qualified rate, can't satisfy the production needs of external mercury amalgam energy-saving tube.

[summary of the invention]

The technical assignment of the technical problem to be solved in the present invention and proposition is the technological deficiency that overcomes existing single air exhaust rod mercury rifle, and a kind of two glass rods that dock simultaneously are provided, and vacuumizes the mercury gun with double exhaust stroke of better effects if.

The technical solution used in the present invention is: mercury gun with double exhaust stroke, the rifle body that comprises a band inner chamber, rifle body one side is provided with the blast pipe that communicates with inner chamber, be equipped with by sealing cap described inner chamber upper end, seal, sealing ring, upper pressing cap, the mercury seat that cover for seat and magnetic conduction inner core are formed, rifle intracoelomic cavity lower end is provided with the seal nipple that connects the fluorescent tube glass rod, what the sealing street corner comprised coaxial serial connection from top to bottom connects the mercury bucket, sealing gasket and compressing member, rifle body bottom is provided with external screw thread and is being spirally connected a lower pressing cap that upwards withstands compressing member, it is characterized in that the off-axis position is installed with the through hole that communicates with the rifle intracoelomic cavity on described sealing gasket and the compressing member, be provided with one in the through hole on the compressing member and adjust obstruction, which is provided with axial exhaust hole.By on existing seal nipple, increasing an exhaust hole, make two glass rods of fluorescent tube and mercury rifle dock together and vacuumize, accelerated exhaust velocity greatly, significantly improve exhaust quality; Two glass rods after the processing are sintering together, once seals, and the manufacturing process that existing twice sintering sealed glass rod more simplifies, and helps improving manufacturing schedule, increases the fluorescent tube production capacity.

Rifle body described in the present invention is around the sidewall hollow of inner chamber, and the rifle body side surface is provided with inlet tube and outlet tube and hollow side wall is communicated with.The rifle body sidewall of existing single layer structure is had the double-decker of interlayer instead, and by cooling off the mercury rifle to the hollow side wall water filling, simple in structure in the use, cooling effect is good, avoids the air-cooled noise that brings.

The supporting surface of corresponding compressing member is equipped with plain thrust bearing on the lower pressing cap described in the present invention.The effect of bearing be when alleviating lower pressing cap and rotating to the friction of compressing member, operation was more laborsaving when lower pressing cap rotatably compressed.Wherein said plain thrust bearing can firsthand needle thrust bearing.

Magnetic conduction inner core described in the utility model is respectively permeability magnetic material and non-magnet material for upper and lower two sections.Avoid the magnetic conduction inner core to pollute by the magnetic conduction position that limits the magnetic conduction inner core, guarantee to drip mercury stability to the Overall magnetization of mercury rifle with to the magnetization of mercury.

The utility model vacuumizes two glass rod butt joints of mercury rifle and fluorescent tube by increase an exhaust hole on the seal nipple of mercury rifle bottom, accelerates exhaust velocity, improves exhaust quality; Two glass rods after processing together sintering seal, need not sintering twice, manufacturing process more simplifies, and uses the mercury gun with double exhaust stroke of this structure to help enhance production progress, improves the fluorescent tube production capacity.
