Abstract

The utility model relates to an anti-revolving festival lamp bulb and a bayonet peg thereof. The anti-revolving festival lamp bulb is composed of a glass shell, a filament and a filament pin, and the tail part of the lamp bulb is flatly pressed into a cuboid or an ellipse cylindrical body. The bayonet peg is composed of a shell body, a coil-out hole and an inner cavity, and the size and the shape of the inner cavity correspond to those of the tail part of the lamp bulb. The utility model can prevent the lamp bulb from rotating to cause two feet of the filament to be in short circuit, and ensure the use reliability. The utility model can effectively enhance the production efficiency, reduce the breakage of the lamp bulb in an assembly process, decrease the cost, and is suitable for the mass production.

Description

Anti-revolving festival lamp bulb and its base (bayonet peg)

The utility model relates to a kind of rotating-proof festival bulb and lamp holder lock pin matching used with it.

The finding festival bulb comprises in order to control the control bubble that one group of series connection goes out when bright during Holiday lamp and (adds the sheet of beating in the bubble in the market, claim to jump bubble again), its afterbody is circle, because be circular, just rotate easily, the filament bipod in order to connect power supply that causes afterbody to be drawn causes short trouble, for this reason, when the color lamp assembling is dispatched from the factory, every bulb will be inserted the lamp holder lock pin by tight squeezing, with anti-rotation, obviously this just certainly will influence production efficiency, and cause the bulb breakage easily, so that the manufacturing dimension of bulb external diameter is had to propose high requirement, thereby improved cost.

The purpose of this utility model provides a kind of festival bulb and lamp holder lock pin matching used with it that can prevent effectively that bulb from rotating.

The utility model is so to realize: rotating-proof festival bulb is made up of glass shell, filament and filament leg, the afterbody that it is characterized in that bulb is cuboid or oval cylinder, the lamp holder lock pin that matches with it, be made up of housing, wire hole and inner chamber, the inner chamber that it is characterized in that lock pin leaves cuboid or the cylindroid body space with the corresponding size of bulb tail.

From the above, the utility model has fundamentally solved festival bulb effectively and has caused the short trouble problem because of rotation, guarantees the reliability used and this design.Needn't propose the manufacturing dimension of bulb external diameter to be strict with, the cooperation of bulb and lamp holder lock pin also needn't reach the purpose of anti-rotation with tight way of squeezing, so can enhance productivity significantly, be suitable for production in enormous quantities, and can avoid bulb again because of the tight crowded breakage that causes, these all can help to reduce cost.

Now as follows with following embodiment and description of drawings thereof:

Fig. 1 is the front view of rotating-proof festival bulb;

Fig. 2 is the end view of rotating-proof festival bulb;

Fig. 3 is the cutaway view of lamp holder lock pin;

Fig. 4 is a lamp holder lock pin A-A view;

Fig. 5 is the assembling schematic diagram of bulb and lamp holder lock pin.

As shown in Figure 1, 2, rotating-proof festival bulb is made up of glass shell 1, filament 2 and filament leg 4, and bulb tail 5 is flattened into cuboid or oval cylinder.Cause extinguishing of one group of series connection bulb for anti-because of a certain light bulb filament opens circuit, the filament bipod place in bulb is connected with resistance wire 3.Shown in Fig. 3,4, the lamp holder lock pin is made up of housing 6, inner chamber 7 and wire hole 8, the size of inner chamber 7 and shape are made the festival bulb afterbody 5 that matches with it and are adapted, and are cuboid or oval cylinder, and respectively there is a filament leg location notch 9 in the outside, aperture of two wire holes 8.

Claims

1, a kind of rotating-proof festival bulb is made up of glass shell [1], filament [2] and filament leg [4], and the afterbody [5] that it is characterized in that bulb is cuboid or oval cylinder.

2, the matching used lamp holder lock pin of the described rotating-proof festival bulb of a kind of and claim 1, be made up of housing ［ 6 ］, inner chamber ［ 7 ］ and wire hole ［ 8 ］, the inner chamber ［ 7 ］ that it is characterized in that the lamp holder lock pin leaves cuboid or the cylindroid body space with the corresponding size of bulb tail ［ 5 ］.

3, lamp holder lock pin according to claim 2 is characterized in that respectively there is a filament leg location notch ［ 9 ］ in the outside, aperture of two wire holes ［ 8 ］.
