Abstract
The utility model discloses a lead-free glass core column comprising a horn tube and a gas discharge tube, wherein the gas discharge tube is sleeved with the horn tube, a gas discharge tube part outside the horn tube is provided with upper and lower contraction sections, the two contraction sections are arranged on the gas discharge tube in a top-to-bottom manner and are in a state that a single edge of each contraction section is constricted into the gas discharge tube, the contraction amount of each contraction section on the gas discharge tube is larger than the radius of the gas discharge tube, and the two contraction sections are opposite in contraction direction. The single-edge contraction sections are oppositely arranged on the gas discharge tubes. The inner part of the gas discharge tube is provided with a spherical baffling block which is arranged between the two contraction sections, and the diameter of the spherical baffling block is larger than the radius of the gas discharge tube. The lead-free glass core column is characterized by simple structure, convenience of processing and manufacturing operation, low cost, and stability and safety of utilization. Mercury can be effectively prevented from falling into a lamp tube while the overall strength and the service life of the gas discharge tube are considered, and the lead-free glass core column is suitable for production and utilization of mercury lamps which are different in standard and performance parameter requirements.
Description
Technical field
The utility model relates to the mercury lamp field, is a kind of crown glass stem stem specifically.
Background technology
In the tradition mercury lamp, the performance of photoelectric parameter is to be determined by its internal resistance tile height, and after stop block added blast pipe, with the blast pipe exhaust of bending, the placement of its stop block and the processing of mercury lamp were 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 in order to ensure make, when using, mercury is not fallen in fluorescent tube, affects the 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, it is a kind of simple in structure that the utility model provides, processing, easy to make, and cost is low, uses stable, safety, can prevent effectively that mercury from falling into the crown glass stem stem that fluorescent tube is taken into account blast pipe bulk strength and useful life simultaneously.
The technical solution adopted in the utility model is: a kind of crown glass stem stem, comprise oviduct and blast pipe, exhaust shroud is connected in oviduct, it is characterized in that: the outer blast pipe of described oviduct partly is provided with upper and lower contraction section, upper and lower being arranged at of two contraction sections is monolateral contraction air inlet-outlet pipe state on blast pipe, the amount of contraction of contraction section on blast pipe is less than the blast pipe radius, and two contraction section shrinkage directions are opposing; Be provided with spherical stop block in blast pipe between two contraction sections, spherical stop block diameter is greater than the blast pipe radius.
The utility model has the advantages that: contraction section is monolateral contraction, the two opposing settings of contraction section, the contraction structure intersection can effectively prevent, stop mercury to fall into fluorescent tube, and the amount of contraction of contraction section is easy to process less than the blast pipe diameter, and not fragile, rate of finished products is high, during use, intensity is high, easy fracture not, quality is good, uses safety.
The utility model 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 prevent effectively that mercury from falling into fluorescent tube and taking into account simultaneously blast pipe bulk strength and useful life, be fit to mercury lamp production and instructions for use that different size and performance parameter require.
Description of drawings
Fig. 1 is the utility model structural representation.
In figure: oviduct 1, blast pipe 2, upper contraction section 3, lower contraction section 4, spherical stop block 5, seal wire 6.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Shown in Figure 1, a kind of lamp comprises oviduct 1 and blast pipe 2 with the crown glass stem stem, blast pipe 2 and seal wire 6 are connected in oviduct 1, oviduct 1 outer blast pipe 2 parts are provided with upper and lower contraction section 3,4, upper and lower contraction section 3,4 upper and lower being arranged at are monolateral contraction air inlet-outlet pipe 2 states on blast pipe 2, upper and lower contraction section 3,4 amount of contraction are less than blast pipe 2 radiuses, two contraction section shrinkage directions are opposing, be provided with spherical stop block 5 in blast pipe between two contraction sections, the diameter of spherical stop block is greater than blast pipe 2 radiuses.
