11,12 are passed through at the two ends at fixing arm 1, carrier 23

jointings

21,22 are passed through at two ends at full wind-up 2, and this

joint

11,12,21,22 is provided with perforation 111,121,211,221 respectively; Inwall at an end connector 11 of fixing arm is provided with retainer ring 112, at an end connector 21 inwalls of full wind-up retainer ring 212 is set; Connection Element 3 comprise connector 31, two wear-resistant hold sheet 32,32 ', two packing rings 33,33 ', connector 31 inner hollow, one end is established flanged ring 311, the other end is inserted in packing ring 33, two wear-resistantly hold the inner fovea part that sheet embeds fixing arm and full wind-up respectively, run through via connector 31, this connector one end stretches out and forms locating ring 34; Wear-resistant hold sheet 32,32 ' thickness greater than joint inner edge inner fovea part; Retainer ring 112,212 positive and negatives are provided with relative shrinkage pool, and 1121,2121, with the salient point 331,331 that is provided with on the packing ring ' chimeric.

The utlity model has following characteristics:

1. be provided with the joint of global formation at the utility model fixing arm and full wind-up two ends, make in conjunction with firmly being easy to.

2. Connection Element all adopts unified normalized assembly, is fit to industrialized mass production, and cost is low.

3. the connected mode of composition element all adopts fixed form and general technology, construction easy.

4. Connection Element adopts copper material, makes structure wearability height, long service life.

5. all component is all built-in hidden, specious.

6. all component connection is rationally perfect, is easy to promotion and implementation.

Now further narrate the utility model in conjunction with the accompanying drawings.

Referring to Fig. 1-6, the utility model comprises fixing arm 1, full wind-up 2 and Connection Element 3.Wherein fixing arm 1 is an aluminium matter tubing, and two ends are provided with the carrier 13 to external taper, so as with jig on the

direct joint

11,12 of extrusion integral moulding, increase adsorption area in conjunction with firmly.The same carrier that has to external taper that is provided with in the two ends of full wind-up 2 is so that increase adsorption area and combine firm with joint 211,221.At

joint

11,12 perforation 111,121 is set, forms passage for fixing arm 1.

Joint

21,22 is also established perforation 211,221.Electric wire 4 is through perforation 121 and fixing arm 1 inside, full wind-up 2 inside, and boring a hole certainly 221 passes; End connector 11 at fixing arm 1 is provided with retainer ring 112, also establishes retainer ring 2121 at an end connector 21 of full wind-up 2, runs through for Connection Element 3, and this Connection Element makes fixing arm 1 combine with full wind-up 2.Protruding seat 222 by groove seat 122 on the joint 12 of fixing arm 1 and full wind-up 2 joints 22 is chimeric, returns back to original position to amount to.

Connection Element 3 comprise connector 31, wear-resistant hold sheet 32,32 ', two packing rings 33,33 ', the inside of connector 31 is hollow form, the empty prominent flanged ring 311 of establishing of one end, end is inserted in packing ring 33 in addition, and will preset two wear-resistantly hold that sheet 32,32 ' respectively is embedded in the inner fovea part 113 of fixing arm 1 joint 11 and the inner fovea part of full wind-up 2 joints 21 runs through with connector 31, make an end of connector 31 be inserted in packing ring 33 ', by the extruding expansion pattern, connector 31 1 ends are stretched out to be formed locating ring 34 and is connected to form one.

Because the two wear-resistant sheets 32 that hold, 32 ' combine with inner fovea part form integral body after, still can locate rotation, form two surface wears, so at the two wear-resistant sheets 32 that hold, 32 ' both sides are provided with salient point 321,321 ', can be embedded in retainer ring 112 respectively, the shrinkage pool 1121 of 212 tops, 2121, form interlock, two packing rings 33 in addition, 33 ' also are provided with salient point 331,331 ', can be embedded in retainer ring 112, the shrinkage pool 1121 of 212 belows ', 2121 ', form lopsided wear, reduce the consume area, the wear-resistant again sheet 32 that holds, 32 ' thickness is slightly larger than joint 11,21 inner fovea part can reduce joint 11,21 mutual frictions.

In an embodiment:

joint

21,22 can adopt aluminium alloy or iron zinc to make, and Connection Element adopts copper material.
