Abstract
The utility model discloses a structure of PAR type heating bulb. The prior art PAR bulb designs suffer from certain deficiencies: the lamp holder with the machine riveting causes not hard up and the droing of lamp holder very easily, the technical scheme of the utility model is that take the lamp holder structure subassembly of integral type, the metal lamp holder is directly twisted on the screw thread of glass bulb, the utility model discloses seal position, the fixed notch of lamp holder, wick, lamp cup and the bowl cover by the screw thread, the wick horn tube of seal wire, blast pipe, fixed lamp holder and the screw thread of lamp cup afterbody and constitute, the positive effect of the utility model lies in: the lamp cap screwed and fixed by the screw thread at the tail part of the glass lamp cup is not easy to fall off or loosen; the probability of the phenomenon of air leakage and whitening of the bulb in the utility model is very low, and the product quality can be very stable; meanwhile, the production process of the bulb is simplified, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of heating system, particularly relates to a kind of structure of PAR type heating bulb.
Background technology
PAR type heating bulb during heating is not equipped with is a kind of traditional heating system, uses and has for many years the rare improvement of its production method and product structure: show the production process complexity, production efficiency is difficult to be improved; Be reflected in the structure and the product of bulb, also coming with some shortcomings qualitatively of product as vitreous lamp holder machine riveted, and has only two fixing points, is easy to cause the loosening of lamp holder and come off, and the glass dielectric layer in the middle of the lamp holder also is easy to become flexible, fragmentation.
Summary of the invention
In order to overcome the deficiencies in the prior art, improve the quality of traditional PAR bulb production method and raising PAR heating bulb, it is the purpose of this utility model place that a kind of PAR heating bulb is provided, the technical solution of the utility model is to improve the holder structure of conventional P AR type heating bulb, be made of one the holder structure assembly of formula, glass dielectric layer in the middle of not having, metallic lamp holder directly is screwed on the screw thread of glass bulb, the technical solution of the utility model is to come specific implementation by following technical measures: a kind of PAR type heating bulb, it is characterized in that it is by seal wire, blast pipe, the fixing screw thread used of lamp holder, the closure part of wick glass horn pipe and Lamp cup afterbody, lamp holder is notch fixedly, wick, Lamp cup and bowl cover are formed (seeing accompanying drawing 1), described wick is an assembly, comprise filament, ceramic disk, nickel wire, tungsten bar and glass horn pipe (seeing accompanying drawing 2), wherein: filament is installed on the molybdenum filament support of wick end, and weld with the nickel wire spot welding machine respectively at two of filament; Seal wire and blast pipe are directly drawn from wick; Nickel wire and seal wire connect by the tungsten bar, and the tungsten bar is with glass horn pipe involution; The head of Lamp cup and bowl cover fire envelope involution, the glass horn pipe of wick becomes the closure part of wick oviduct and Lamp cup afterbody with the direct involution of Lamp cup afterbody glass bulb screw thread, and the glass-dead seal of involution forms the fixedly screw thread used of lamp holder of screw-shaped outward; The fixed form of metalized lamp head capsule is directly to be screwed in the glass-dead seal of Lamp cup tailing screw flight, rather than with glass bulb on the fixed form of conventional bulb of two location hole riveteds.Filament material described in the utility model adopts tungsten filament; Described seal wire material adopts nickel wire.
Good effect of the present utility model is: be not easy to come off or loosening at the fixing lamp holder of glass Lamp cup tailing screw flight mode; Nickel wire is connected by the tungsten bar with seal wire, and uses the glass involution, and the coefficient of expansion of tungsten and glass is very approaching, and contact area is very little again, so bulb leaks gas, the probability of bulb albinism in the utility model is very low because of coefficient of expansion difference causes, product quality can be very stable; Simultaneously, the utility model directly carries out the processing method of the disposable involution of wick, Lamp cup and bowl cover, has simplified the production process of bulb, has improved production efficiency.
Description of drawings
Fig. 1: a kind of PAR type of the utility model heating bulb structural representation;

Embodiment
Be further described below in conjunction with embodiment and 1,2 pairs of the utility model of accompanying drawing:
The structure of the PAR type heating bulb of the 125V175W that uses on a kind of hospitalize equipment, it by the seal wire 1 of nickel matter, blast pipe 2, fixedly closure part 4, the lamp holder of screw thread 3, wick glass horn pipe and the Lamp cup afterbody used of lamp holder fixedly notch 5, wick column 6, Lamp cup 7 and bowl cover 8 are formed (seeing accompanying drawing 1), described wick column 6 is assemblies, comprises filament 9, the diameter of tungsten filament
The ceramic disk 10 of 32mm, diameter
1.5mm nickel wire 11, diameter
0.8mm tungsten bar 12 and glass horn pipe 13 (seeing accompanying drawing 2), these parts are pressed the structure of Fig. 1 and Fig. 2 and are installed.Wherein: filament 9 is installed on the molybdenum filament support of wick end, and weld with nickel wire 11 usefulness spot welding machines respectively at two of filament 9; Seal wire 1 and blast pipe 2 are directly drawn from wick; Nickel wire 11 and seal wire 1 connect by tungsten bar 12, and the tungsten bar is with glass horn pipe involution; The head of the Lamp cup 7 of glass quality and the bowl cover of glass quality 8 fire envelope involutions, the glass horn pipe 13 of wick becomes the closure part 4 of wick oviduct and Lamp cup afterbody with the direct involution of Lamp cup 7 afterbody glass bulb screw threads, the glass-dead seal of involution forms the fixedly screw thread 3 used of lamp holder of screw-shaped outward; The fixed form of R125-E27 metallic lamp holder is directly to be screwed on the screw thread 3 of fixedly lamp holder of closure part 4 of Lamp cup afterbody, rather than with glass bulb on the fixed form of conventional bulb of two location hole riveteds.
