Abstract

The utility model discloses a chain light string, which comprises a wire, and a bulb installed on the wire. The wire comprises a first branch wire and a second branch wire, the first branch wire and the second branch wire are both provided with the respective and independent positive electrode and negative electrode wires, to form a power supply circuit, a plurality of bulbs on each branch wire are connected between the positive electrode wire and the negative electrode wire on the branch wires in parallel, a plurality of segments of light-transmitting pipes are respectively nested outside the bulbs, and the first branch wire and the second branch wire and the bulbs on the wires are intercrossed and connected into a chain structure through the light-transmitting pipes. The independent light-transmitting pipes are respectively nested outside the bulbs, when the chain light string is manufactured, all the bulbs on the first branch wire and on the second branch wire can be connected in parallel and well welded, and when being assembled, only the bulbs are required to be penetrated into the light-transmitting pipes, and the two branch wires are intercrossed and connected to form chain structural light strings with different models according to the model requirements. The chain light string has the advantages that the structure is simple, the assembly is convenient, the production efficiency is high, the model can be conveniently changed according to the requirements, and a plurality of sets of dies are not required to be manufactured, and thereby the manufacturing cost is greatly reduced.

Description

A kind of chain lamp string

Technical field

The utility model relates to a kind of decorative chain, particularly a kind of chain lamp string.

Background technology

Usually, chain lamp string is to be connected in series successively by a plurality of luminescence units to form.Existing chain lamp string since structural reason to make technology very complicated, its cell cube is injection molded by hard plastics, this cell cube comprises the end box and the loam cake that can fasten mutually, end box is provided with the groove of laying bulb and lamp string line.When making chain lamp string, the bulb series connection that needs will be used in earlier in each cell cube is connected to form each branch's lamp string, then in assembling process one by one the welding finished successively between each branch's lamp string and the whole piece lamp string line both positive and negative polarity lead of unit insert, and lamp string line and each branch's lamp string setting-in are gone in the groove of box at the bottom of each cell cube, cover the loam cake of each cell cube at last, thereby finish the installation of this cell cube; Such structure causes its assembling process complexity, and efficient is low, must in assembling process, finish one by one the welding and can not all insert in advance; In addition, for different moulding demands, as the multiple difform chain unit body of needs, just must produce the corresponding injection mold of many covers, its cost of manufacture also is quite high.

The utility model content

In order to address the above problem, the utility model provides a kind of simple in structure, production efficiency is high, variation in moulding is various and cost of manufacture is low chain lamp string.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of chain lamp string, comprise lead and the bulb that is installed on the lead, lead comprises first and second branch line, described first and second branch line all has separately independently, and the both positive and negative polarity lead constitutes electric power loop, there are some bulbs to be connected in parallel between the both positive and negative polarity lead of place branch line on each branch line, described some bulbs are respectively installed with the plurality of sections light-transmission tube outward, described first and second branch line and on bulb intersect cross-under via described light-transmission tube and become chain structure.

As preferred implementation, described each bulb all is set with one section light-transmission tube outward.

The beneficial effects of the utility model are: the utility model is respectively installed with independently light-transmission tube outside bulb, so just can be earlier when making with the bulb on first branch line and second branch line all parallel connection weld, only need during assembling bulb is penetrated in the light-transmission tube, with the cross-under of two branch lines intersection, can form the lamp string of the different chain structure of various moulding according to the moulding needs.It is simple in structure, and is easy to assembly, the production efficiency height, and moulding can realize changing as required easily, and does not need correspondingly to make many molds, greatly reduces cost of manufacture.In addition, shape that also can be by moulding light-transmission tube and outward appearance strengthen it and intersperse effect; For finished product, can also realize DIY, weave the shape of lamp string after taking apart according to the hobby of oneself again.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the structural representation of the utility model one embodiment;

Fig. 2 is the structural representation of another embodiment of the utility model;

Fig. 3 is the structural representation of the third embodiment of the utility model.

The specific embodiment

See figures.1.and.2, a kind of chain lamp string of the present utility model, comprise lead 1 and the bulb 2 that is installed on the lead 1, lead 1 comprises first and

second branch line

10,20, described first and

second branch line

10,20 all has separately independently, and the both positive and negative polarity lead constitutes electric power loop, there are some bulbs 2 to be connected in parallel between the both positive and negative polarity lead of place branch line on each branch line, described some bulbs 2 outer plurality of sections light-transmission tubes 3 that are respectively installed with, described first and

second branch line

10,20 and on bulb 2 intersect cross-under via described light-transmission tube 3 and become chain structure.

In addition, the infall of first and

second branch line

10,20 also can not be provided with bulb, so, can directly be fixed up by the infall with first and

second branch line

10,20 such as wiring, as shown in Figure 3.And every section interior bulb quantity of light-transmission tube also can be one, two or more, all can design according to the concrete needs of decorating.

Light-transmission tube 3 adopts the rounded light-transmission tubes in cross sections usually, also can be other shapes, and as square, triangle etc., the profile that shape by moulding light-transmission tube and outward appearance can make the chain lamp is full of variety more, thereby strengthens the effect of interspersing of chain lamp string.

The utility model is respectively installed with independently light-transmission tube outside bulb, when making, just can earlier the bulb on first branch line and second branch line all be welded like this, only need during assembling bulb is penetrated in the light-transmission tube, according to the moulding needs two branch lines are intersected cross-under, can form the lamp string of the different chain structure of various moulding, as cited among the embodiment; It is simple in structure, and is easy to assembly, the production efficiency height, and moulding can realize changing as required easily, and does not need correspondingly to make many molds, greatly reduces cost of manufacture.

The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
