Abstract
The invention discloses a mercury lamp glass stem which comprises a flare tube and an exhaust tube. The exhaust tube is sleeved with the flare tube. The exhaust tube portion outside the flare tube is provided with upper and lower retraction sections. The two retraction sections are arranged on the exhaust tube in an up-and-down manner and in the state that the two retraction sections are unilaterally retracted into the exhaust tube. The retraction amount of the retraction sections on the exhaust tube is greater than the radius of the exhaust tube. The retraction directions of the two retraction sections are opposite. The unilateral retraction sections are arranged on the exhaust tube oppositely. According to the invention, advantages of simple structure, convenient machining and fabrication, low cost, and stable and safe utilization can be realized, the glass stem can be used to effectively prevent mercury from falling into the lamp tube, and at the same time, the overall strength and service life of the exhaust tube are taken into account, so the glass stem is suitable for the production and utilization requirements of mercury lamps of different specifications and performance parameter requirements.
Description
Technical field
The present invention relates to mercury lamp field, is a kind of mercury lamp glass stem specifically.
Background technology
In tradition mercury lamp, the performance of photoelectric parameter is to be determined by its internal resistance tile height, and stop block adds after blast pipe, and by the blast pipe exhaust of bending, the placement of its stop block and the processing of mercury lamp are loaded down with trivial details, wayward, unstable product quality, and production cost is high.
Existing by the flat mercury lamp that carries out exhaust of exhaust pipe clamp, its mercury when making, use is not fallen in fluorescent tube, affects fluorescent tube parameter, presss from both sides flat place amount of contraction large, affects bulk strength and the useful life of blast pipe.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of simple in structure, processing, easy to make, cost is low, uses stable, safety, can effectively prevent that mercury from falling into fluorescent tube and take into account simultaneously the mercury lamp glass stem in blast pipe bulk strength and useful life.
The technical solution used in the present invention is: a kind of mercury lamp glass stem, comprise oviduct and blast pipe, exhaust shroud is connected in oviduct, it is characterized in that: the outer blast pipe part of described oviduct is provided with upper and lower contraction section, two contraction sections are upper and lower to be arranged at and on blast pipe, to be monolateral contraction air inlet-outlet pipe state, the amount of contraction of contraction section on blast pipe is greater than blast pipe radius, and two contraction section shrinkage directions are opposing.
Advantage of the present invention is: contraction section is monolateral contraction, the opposing setting of two contraction sections, and contraction structure intersection can effectively prevent, stop mercury to fall into fluorescent tube, and the monolateral contraction of blast pipe is easy to process, not fragile, rate of finished products is high, and when use, intensity is high, not easy fracture, quality is good, uses safety.
The present invention is opposing on blast pipe arranges monolateral contraction section, it is simple in structure, processing, easy to make, cost is low, use stable, safety, can effectively prevent that mercury from falling into fluorescent tube and taking into account blast pipe bulk strength and useful life simultaneously, be applicable to mercury lamp production and instructions for use that different size and performance parameter require.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: oviduct 1, blast pipe 2, upper contraction section 3, lower contraction section 4, seal wire 5.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Shown in Fig. 1, a kind of lamp comprises oviduct 1 and blast pipe 2 with mercury lamp glass stem, blast pipe 2 and seal wire 5 are connected in oviduct 1, blast pipe 2 parts outside oviduct 1 are provided with upper and lower contraction section 3,4, upper and lower contraction section 3,4 is upper and lower to be arranged at and on blast pipe 2, to be monolateral contraction air inlet-outlet pipe 2 states, the amount of contraction of upper and lower contraction section 3,4 is greater than blast pipe 2 radiuses, and two contraction section shrinkage directions are opposing.
