Abstract
A small mercury-releasing air suction pipe comprises a metal sleeve and mercury-releasing air suction alloy powder filled in the metal sleeve. The metal sleeve is made of nickel strips or nickel-plated iron strips, the section of the metal sleeve is circular or elliptical, protruding reinforcing ribs are arranged on the inner sides of the sections on two sides of the metal sleeve, the outer sides of the reinforcing ribs are attached to the sections of the metal sleeve, and simultaneously a mercury-releasing air suction groove is arranged in the middle of the sleeve wall of the metal sleeve. The small mercury-releasing air suction pipe is simple in structure, convenient to manufacture, small in finished product sleeve diameter, thin in sleeve wall and durable in use.
Description
Technical field
The utility model relates to mercury-releasing getter elements, is specially the small-sized mercury-releasing getter pipe of using in a kind of fluorescent lamp, compact type energy-saving lamp and the cold-cathode fluorescence lamp processing and making process.
Background technology
China is light fixture big producing country, and its output accounts for global total amount more than 80%, in light fixture manufacturing process, is that fluorescent lamp, high-pressure mercury lamp or electricity-saving lamp all often need to add mercury, in traditional manufacturing process, is to splash into liquid mercury when tube exhaust.Yet this notes mercury mode, poor to the control accuracy of annotating the mercury amount, the consumption of mercury is large, and can cause the fluctuation of argon filling pressure, and performance and life-span of fluorescent tube brought adverse effect.The more important thing is that mercury has larger volatility, the excessive serious environmental pollution that then causes easily of in air, volatilizing, the health that directly endangers operating personnel, and after light fixture termination in useful life, the processing of its mercury also is a larger difficult problem.
Thereby; in the prior art; often can use mercury-releasing getter elements and replace original mercury technology; this mercury-releasing getter elements is widely used in the manufacturing of the mercurous electric light sources such as fluorescent lamp, electricity-saving lamp, cold cathode, backlight of LCD; have human body and environmental pollution little; the mercury amount is easily controlled and waste is lacked, the characteristics that the electric light source life-span that obtains is long.But because the reason of this mercury-releasing getter elements (mostly being sleeve pipe) production technology, metal sleeve easily expands in the process of sleeve pipe production, cause packaging intensity to weaken, in-built powder in use produces easily and comes off, and have influence on the consistency of product powder containing quantity, and finally have influence on the precision of roasting mercury amount.
The utility model content
The technical problem that the utility model solves is to provide a kind of small-sized mercury-releasing getter pipe, and this small-sized mercury-releasing getter pipe caliber is little, and tube wall is thin, and external diameter is stable, and the powder in tube difficult drop-off can be used for solving the problem in the above-mentioned background technology simultaneously.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of small-sized mercury-releasing getter pipe, comprise metal sleeve and be filled in the interior mercury-releasing getter alloy powder of metal sleeve, wherein, described metal sleeve is made by nickel strap or nickel plating sheet iron strip, its tangent plane is circular or oval, and is provided with the reinforcement of protrusion in two side section inboards of metal sleeve, reinforcement outside applying metal sleeve tangent plane, simultaneously, the position also has a mercury-releasing getter groove in the middle of on the tube wall of metal sleeve.
In the utility model, described metal sleeve pipe thickness is 0.4 ~ 0.8mm.
In the utility model, the mercury-releasing getter slot length on the described metal sleeve is 2/3 of metal sleeve length.
Beneficial effect: the utility model is simple in structure, and is easy to make, and its finished product caliber is little, tube wall is thin, good product consistency, and simultaneously, in use, the powder difficult drop-off can effectively prolong useful life of light fixture.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Schematic diagram referring to the preferred embodiment of a kind of small-sized mercury-releasing getter pipe of Fig. 1, in the present embodiment, mercury-releasing getter alloy powder 1 compression also is filled in the metal sleeve 3 that nickel strap makes, metal sleeve 3 tangent planes are circular, pipe thickness is 0.5mm, and its inboard is provided with the reinforcement 2 of protrusion, reinforcement 2 outside applying metal sleeves 3 tangent planes, simultaneously, the position also has a mercury-releasing getter groove 4 in the middle of on the tube wall of the side of metal sleeve 3.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
