A kind of Telescopic rod structure of built-in electric wire, it is hollow including mutual scalable the first hollow stem being nested together and second Bar, inner tube is equipped in second hollow stem, and one end of the first hollow stem is inserted into the second hollow stem and covers in the outer of inner tube Portion；The electric wire enters in the first hollow stem after passing through inner tube.

Telescopic structure in the prior art is conventional set bar type structure, and spring wire is placed in one, is powered and is controlled, But it is at high cost, tangled up and knotted is easy in telescopic process if using common wiring, it is more inconvenient.In the application, by The form of inner tube, this problem of very good solution are set in the second hollow stem.It is hollow that electric wire enters first after inner tube In bar, there are two sections of storage chambers, and since the internal diameter of inner tube is less than the second hollow stem, wind conventional electric wire will not and beat Knot, therefore electric wire that can be built-in conventional, reduce costs.

Preferably, the inside of second hollow stem is equipped with fixed plate, said inner tube is fixed in the fixed plate, structure Simply.

Preferably, one end of said inner tube is equipped with notch, which, which is buckled in fixed plate, realizes fixation, the Standard Convenient, stability is high.

Preferably, said inner tube is equipped with slidable external member, which is connected with one end of the first hollow stem, the knot In structure, guarantee the stability of sliding between external member and inner tube by clearance fit or face contact, so that the first hollow stem and inner tube Opposite sliding stability between the two, will not there is a phenomenon where bias to block.

Preferably, first hollow stem is equipped with outlet hole far from one end of inner tube, the extraction for electric wire is connected to Work drive motor.

Preferably, being equipped with wire outlet seat in the outlet hole, which is used for the extraction of electric wire, guarantees at electric wire bending Smooth transition, wind electric wire will not on the position or excessive tensile, electric wire protected.

Preferably, the outside of first hollow stem is equipped with guide chute, directionality when guaranteeing flexible is good.

Preferably, realizing elastic tune by helicitic texture and lock sleeve between first hollow stem and the second hollow stem Section, it may be convenient to carry out telescopic adjustment length.

Compared with prior art, the utility model has the following beneficial effects: providing a kind of improved telescopic rod Structure, simple and compact for structure, compact can be good at the winding stuck phenomenon of the electric wire avoided, to the protection function of electric wire Can be good, the service life of product is increased, and at low cost, improves the competitiveness of product.
