Abstract
The utility model discloses a lamp lead-free glass core column comprising a horn tube and a gas discharge tube, wherein a part of the gas discharge is sleeved with the horn tube and is provided with two clamping sections, the two clamping 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 clamping section is constricted into the gas discharge tube, and the two clamping sections are opposite in contraction direction. he single-edge clamping sections are oppositely arranged on the gas discharge tubes. The lamp 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 lamp 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 fluorescent tube and taking into account simultaneously the lamp in blast pipe bulk strength and useful life crown glass stem stem.
The technical solution adopted in the utility model is: a kind of lamp crown glass stem stem, comprise oviduct and blast pipe, it is characterized in that: the part that described exhaust shroud is connected in oviduct is provided with two clamp segment, upper and lower being arranged at of two clamp segment is monolateral contraction air inlet-outlet pipe state on blast pipe, two clamp segment shrinkage directions are opposing.
Further, described two clamp segment are 5mm along blast pipe direction distance.
Again further, be provided with spherical stop block in the blast pipe between described two clamp segment.
The utility model has the advantages that: clamp segment is monolateral contraction, the two opposing settings of clamp segment, and the contraction structure intersection can effectively prevent, stop mercury to fall into fluorescent tube, and easy to process, not fragile, rate of finished products is high, and during use, intensity is high, easy fracture not, quality is good, uses safety;
The utility model is opposing on blast pipe arranges monolateral clamp segment, 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 clamp segment 3, lower clamp segment 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 1,1 section blast pipe 2 part of corresponding oviduct are provided with upper and lower clamp segment 3,4, upper and lower clamp segment 3,4 upper and lower being arranged at are monolateral contraction air inlet-outlet pipe 2 states on blast pipe 2, two clamp segment shrinkage directions are opposing, and two clamp segment are 5mm along blast pipe direction distance, are provided with spherical stop block 5 in the blast pipe between two clamp segment.
Claims (3)
