Embodiment 1

It is shown in Figure 4 to consult Fig. 1 one, and the telescoping tube structure of lamp decoration of the present utility model has outer tubule 1, one outer extra heavy pipe 2, one an interior extra heavy pipe 7, the inside and outside double-deck telescopic tube of an inner tubule 6 formation with conducting positive pole and negative pole, and integral body is an antenna formula bar that is commonly called as.

Be connected to a male joint 4 in the upper end of outer tubule 1, a termination of outer extra heavy pipe 2 has a female joint 9, and the male and female joint all has electric conductivity.In the male joint 4 is through hole 41, is distinguished into first and second by an interior ring edge 43 in the through hole 41, and second of through hole 41 is and the upper end Joint part of outer tubule 1 that first of through hole 41 penetrates a resilient engagement body 5.

This resilient engagement body 5 becomes the insulated part of male joint 4 for the insulation shell that is the semicircle tubulose 51 with two halves is combined into the short bushing pipe of an insulation with the short bushing pipe that insulate.Be provided with an inward flange 53 in the middle of each insulation shell 51 in the short bushing pipe of insulation and be distinguished into inner room 521 and mistress's 531 two parts, and be provided with the location bead 52 of inside projection in the inner face bottom of insulation shell 51, space with location bead 52 and 53 formation inner rooms 521 of inward flange, can be equipped with the lower end 58 of a spring 55 and a trolley shoe 56 in the inner room 521, because the major part of this trolley shoe 56 is for placing mistress 531, so, on trolley shoe 56, be provided with a recessed neck 57, be placed in inward flange 53 relatively with recessed neck 57, and allow recessed neck 57 slide in inward flange 53 places.

The part upper end of this trolley shoe 56 is the short bushing pipe of outstanding formed insulation top, and insulation shell 51 upper ends have an outstanding outer rim 54, make this outer rim 54 be buckled in external screw thread 42 ends of the upper end of male joint 4.

Be provided with a slotted eye 561 in the trolley shoe 56, this slotted eye 561 is to offering by the lower surface upward axis, and be provided with a side opening 59, with slotted eye 56 allow the upper end of this inner tubule 6 place into, a side is provided with a planar portions 61 in the upper end of inner tubule 6, pass side opening 59 formed screws and join with hexagon socket head cap screw 50 formed fixation kits, locating of male joint 4 is fixed in the upper end of inner tubule 6 with the planar portions 61 of these inner tubule 6 upper ends.

The inner surface place of outer tubule 1 is with an insulation inner sleeve 3, and with the insulation as outer tubule 1 and inner tubule 6, this insulation inner sleeve 3 can be a fiberglass sleeve, has dilatancy, can directly expand to be stuck in the outer tubule 1.The lower end of outer tubule 1 is to socket-connect with outer extra heavy pipe 2, the both sides, nearly lower end of tubule 1 respectively are provided with a perforation 11 outside, respectively are provided with a holding piece 12 in the both sides of each perforation 11, make and are extended with a fixed leg 13 on the holding piece 12, fixed leg 13 inserts in perforation 11, even holding piece 12 is sandwiched in the both sides of outer tubule 1.

The upper end of outer extra heavy pipe 2 is for forming inside button edge 21, with prevent to wear into outer tubule 1 lower end can not skid off by the upper end of outer extra heavy pipe 2; And outer extra heavy pipe 2 and 1 utmost point that forms conduction of outer tubule, so, the conductive hollow pipe that outer extra heavy pipe 2 and outer tubule 1 tool are metal structure.

The appearance place of interior extra heavy pipe 7 is with the insulating coating pipe 8 of a pyrocondensation, can make inner tubule 6 is the copper rod of a metal, interior extra heavy pipe is the copper pipe of a metal, both are nested, inner tubule 6 can be moved up and down in interior extra heavy pipe 7, the insulating sleeve 8 of this pyrocondensation is to be a gum cover, the appearance of extra heavy pipe 7 in being fixed in the mode of heating cover; Because the lower end of interior extra heavy pipe 7 is connected to a fixing piece 70 that connects, connecting piece 70 is to form the lower end of an engaging groove 71 with extra heavy pipe 7 in being connected with.

Also consistent break-through road 91 in the female joint 9, also be to be distinguished into two halves in the penetrating via 91 with an interior empty edge 93, second lower end of penetrating via 91 is for being provided with internal thread 92, the upper end of penetrating via 91 is the lower end that is connected to outer extra heavy pipe 2, after extra heavy pipe 7 is located to pass by the hole of inward flange 93 in making, allow this connect the place, below that piece 70 is placed in inward flange 93, and mat one insulation certainly 10 is positioned in the inward flange 93 of female joint 9, collets 10 are to be stuck in to run through to gush second place of 91, clip and connect piece 70, and collets 10 pass inward flange 93, to form the insulation of female joint 9 inside.

Consult shown in Figure 4ly, the utility model can form the pattern that three poles are joined, and that is to say that female joint 9 internal threads 92 of external screw thread 42 and another bar of male joint 4 of the upper end of bar join, and male joint 4, female joint 9 can be connected to form the serial connection form.So, just can be connected into very long structure with telescopic structure of the present utility model uses.

Embodiment 2

Consult Fig. 5, shown in 6, male joint 4 external screw threads 42 of the present utility model are connected to the female joint 100 of another butt joint, this female joint 100 is for can be arranged in a holder 110 places, this female joint 100 shows with the form of power supply, so show the electric wire of quoting 101,102, and each electric wire 101,102 connect respectively and connect an electric piece 103 and an external electric shell 104 in one, separate with isolated insulation cover 105 therebetween, the form of approximate above-mentioned female joint, the internal thread 92 of the female joint 9 of present embodiment then is connected to the male joint 4 of another butt joint, join owing to can stretch into for an electric wire in the male joint 4 of present embodiment, so, can insert with a coaxial electric wire 210 and join, mode is the same, so power supply can be transmitted behind present embodiment by the female joint 100 of butt joint, changes coaxial cord 210 to one light fixtures 200 places, this light fixture 200 is for to be applicable to a kind of form of Halogen lamp LED, but do not exceed with this form.And the holder of upper end also can connect the form of female joint for same shaft cable, and the lower end connects to the light fixture place with the male joint of docking or also can in other electricity conductive construction place.

Structure in sum, the utility model use external electric pathway with in connect electric pathway two paths and replace electric wire, and the structure of length is adjusted in the formation flexible, it is formed at the electric pathway that connects of appearance with male joint 4 to outer tubule 1 to outer extra heavy pipe 2 to female joint 9, again 6 to form the inner electric pathway that connects to connecting piece 70 to interior extra heavy pipe 7 in trolley shoe 56 to inner tubule; And also be that male joint 4 is joined with female joint 9 when docking up and down, trolley shoe 56 with connect piece 70 and join, and because trolley shoe 56 has sliding, can produce suitable bonding tightness, so that better adjustment to be provided, the joint so can link to each other with many multi-form structures can provide fine usability, be one fully with different mechanism commonly used.
