CN202152313U - Sealing-off fire head for production of fluorescent lamps - Google Patents

Abstract

The utility model relates to a sealing-off fire head for the production of fluorescent lamps, which comprises a fire head body (1), wherein a gas storage hole (2) communicated with a fuel gas source is formed in the middle of the front end of the fire head body (1); a plurality of fire outlet holes (3) vertical to the gas storage hole (2) are formed at the front end of the gas storage hole (2); the axial included angle between the fire outlet holes (3) and the fire head body (1) ranges from 5 to 35 degrees; and the diameter of each fire outlet hole (3) ranges from 0.3 to 0.5 mm. The sealing-off fire head for the production of the fluorescent lamps has a simple structure and can effectively avoid the problem in sealing the gas discharge pipe off that a glass stick and a gas discharge pipe have inconsistent heights after the gas discharge pipe is sealed off due to uneven wall thickness of the gas discharge pipe. In addition, due to small preheated area, solid mercury is not easy to melt and fall into a lamp tube in the making process of solid mercury.

Description

Produce fluorescent-lamp-use sealed-off duration and degree of heating

Technical field:

The utility model relates to a kind of duration and degree of heating, relates in particular to a kind of production fluorescent-lamp-use sealed-off duration and degree of heating.

Background technology:

During current luminescent lamp was produced, traditional sealed-off duration and degree of heating all was to add the wind duration and degree of heating with the naked light formula, and owing to reasons such as the external diameter of luminescent lamp vapor pipe and wall thickness are inconsistent; The difference in height of vapor pipe is bigger when often causing the luminescent lamp sealed-off; Glass after sealed-off stalk highly is easy to surpass 3 millimeters, moreover since the naked light formula to add wind duration and degree of heating preheating area big, burn the loudspeaker of broken sealing part easily; And when doing solid mercury, will consolidate the mercury fusing easily, drop in the lamp.

The utility model content:

The purpose that the utility model is wanted is in order to overcome the above-mentioned deficiency of prior art, a kind of production fluorescent-lamp-use sealed-off duration and degree of heating to be provided, and this sealed-off duration and degree of heating is simple in structure, and can effectively overcome the production defective that causes because of the exhaust wall thickness ununiformity.

For solving the problems of the technologies described above, the utility model adopts following technical scheme to be:

Produce fluorescent-lamp-use sealed-off duration and degree of heating, comprise duration and degree of heating body (1), wherein, the front center of said duration and degree of heating body (1) is provided with the gas storage hole (2) that communicates with fuel gas source, and the front end in gas storage hole (2) is provided with and gas storage hole (2) vertical a plurality of fire output holes (3); Said fire output hole (3) is 5～35 ° with the axial angle of duration and degree of heating body (1), and the diameter of fire output hole (3) is 0.3～0.5mm.

Further, the quantity of said fire output hole (3) is 7.

Further, the material of said duration and degree of heating body (1) is a stainless steel.

Further, the material of said duration and degree of heating body (1) is a copper base alloy.

The beneficial effect of the utility model is: compared with prior art; The utility model simple in structure; And can effectively overcome the highly inconsistent problem of sealed-off final vacuum pipe glass stalk that causes because of the exhaust wall thickness ununiformity during sealed-off vapor pipe; And, and when doing solid mercury, be not easy solid mercury fusing is dropped in the fluorescent tube because the preheating area is little.
