Abstract
The utility model relates to a tungsten filament end folding type positioning structure for a lamp bulb. The lamp bulb is provided with two conductive wires, and a tungsten filament is arranged between the ends of two conductive wires. The ends, which are buckled with the tungsten filament, of the conductive wires are manufactured into reflexed hooks via tools so as to place and support two flat and straight segments of the tungsten filament, and then the tungsten filament and the conductive wires are combined into integration; therefore, a lamp bulb finished product is formed. The utility model has the advantage of more stable quality, and the utility model can efficiently prevent that the material and the time are wasted because the tungsten filament is detached after installed.
Description
The utility model relates to a kind of lamp pearl tungsten filament location structure, particularly relate to a kind of can be more firm tungsten filament is positioned the seal wire end, make lamp pearl quality more stable and prevent the lamp pearl tungsten filament end folding formula location structure that bad product produces in the production process.
With the lamp pearl that is used in Christmans light string and so on is example, on its structure mostly is to make two seal wire energisings that separate, and makes a tungsten filament that is combined between two seal wires luminous because of energising then.Therefore, on the making practice of lamp pearl, must process the end that the tungsten filament of a length-specific is positioned these seal wires then earlier with two seal wire location.
See also shown in Figure 1, be used in the lamp pearl of Christmans light string, no matter be to contain the jumping bubble of bimetal leaf or simple son bubble, the tungsten filament 12 that all must connect one section length-specific of combination, the two straight flat sections 13,14 that make this tungsten filament 12 in the end of two seal wires 10,11 directly and the surfaces of seal wire 10,11 recline and join and make up.
The tungsten filament combining structure that this kind commonly used the lamp pearl is made at the scene and many shortcomings is arranged during actual the use.With field fabrication in the factory, because seal wire 10,11 itself is mostly made the strip of circular cross section, its surface is quite smooth, when its two ends directly being put down section 13,14 with the operation of button silk execution of instrument snapping, quite is not easy construction.In addition, more because the sliding contact site of its straight zero diopter, and make the intensity after the combination be on duty mutually, when in factory, making, the undercapacity that the Chang Yinqi shiny surface interosculates, and forming the phenomenon of monolateral or bilateral disengaging, the lamp pearl quality of not only making is undesirable, and this kind faulty materials also often cause the waste in material man-hour etc.
The purpose of this utility model is, overcome the shortcoming of prior art, and provide a kind of structure improved lamp pearl tungsten filament end to roll over the formula location structure, make it mainly do twice directly to bending with instrument earlier to the tungsten filament combination end of each seal wire, make this end fold the hook end of a suitable length, thereby the snapping that the two straight flat sections that make tungsten filament can be stabilized is combined in these hook ends, can prevent to produce the effect that tungsten filament combination retrolisthesis causes the flaw defective products and have.
The purpose of this utility model is realized by following technical scheme: a kind of lamp pearl tungsten filament end folding formula location structure, and its lamp pearl is provided with two seal wires that separate, and is combined with a tungsten filament between two seal wire ends; The straight flat section that this tungsten filament two tops are established is fastened on these seal wire ends, it is characterized in that: the end of these seal wire snapping tungsten filaments is and is made as the reflexed hook shape.
The purpose of this utility model also can further realize by following technical measures, and aforementioned lamps pearl tungsten filament end folding formula location structure is characterized in that the directly flat section in wherein said tungsten filament two ends puts above-mentioned reflexed hook end and be combined into one buckle an instrument.
The utility model compared with prior art has tangible advantage and good effect.By above technical scheme as can be known, the utility model lamp pearl tungsten filament end folding formula location structure, this lamp pearl is provided with two seal wires, and between two seal wire ends in conjunction with a tungsten filament; Above-mentioned seal wire is made the reflexed hook shape with instrument in advance in the end of its snapping tungsten filament, to bear tungsten filament two flat segments, be combined into one, thereby form a kind of lamp pearl finished product, it is more stable and can prevent from effectively to come off after the tungsten filament combination and cause the effect of material waste in man-hour that it has quality.
In sum, the utility model since the default reflexed hook end that is of seal wire with in conjunction with tungsten filament two flat segments, energy strong fix after it is made up, reduce tungsten filament significantly to buckle the defective products ratio that is easy to come off after the combination of silk instrument, make the quality of finished product more stable, and the waste that has reduced material and man-hour effectively, really be a quite practical improvement design.
Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Fig. 1 is the location structure figure that commonly uses tungsten filament.
Fig. 2 is the stereogram of the utility model embodiment.
Fig. 3 is to use the folding ending tool front view in the utility model embodiment, shows wherein bending action.
Fig. 4 is another action diagram of bending tool among Fig. 3.
See also shown in Figure 2ly, the utility model is used in the lamp pearl tungsten filament end folding formula location structure of lamp pearl, and it also has the seal wire 200,300 that two bars separate, and is combined with tungsten filament 400 in the end of these seal wires 200,300.Principal character of the present utility model promptly is, is provided with reflexed end 201,301 in the end of above-mentioned seal wire 200,300 to form hook portion, makes the flat segments 410,420 of tungsten filament 400 both sides can be for inserting the in addition snapping combination of these hook portions.
In the possible embodiments of making above-mentioned seal wire reflexed hook portion, the folding ending tool that is used in this embodiment as shown in Figure 3, Figure 4, it roughly includes a base 30 combination one drive rods 40 and a rod 50 is formed.
See also shown in Figure 3, when drive rod 40 is subjected to as shown by arrows pressure against the ends, its end casting die 402 will drive drive rod 40 and rod 50 forward simultaneously, make baffle ring 501 be resisted against the side end face 301 of base 30 earlier, make the side right angle breach 51 of rod 50 arrive the location in advance.
When drive rod 40 is subjected to further continuing pressure against the ends, see also shown in Figure 4, the pinch roller 71 of second cross bar 70 will be crossed backarc breach 42, and seal wire 200 ends that this second cross bar 70 pressed to forward folded the first right angle flanging, and make required reflexed hook portion 201, formation can be for the hook end of putting tungsten filament two straight flat sections.After above-mentioned end continues pressure and discharges, promptly because of each back-moving spring 401,500,64,72 member is recovered back original position again.
