Abstract
A telescopic coupling link for positioning bars for hanging window curtains and towels on the wall of the door, window or cabinet. Wherein, an inner pipe and an outer pipe which have different diameters are in socket joint and are moveable; a subuliform bolt are provided in the socket joint pipe and the subuliform screw which is connected with the inner tube head is located by the pressing of the inner pipe wall and can rotate with the inner pipe wall, and the subuliform nut is an unclosed ring; in a free state, the external diameter of the subuliform nut is bigger than the inner diameter of the external pipe and is positioned in the external pipe by closing the ring; a nut is fixed near one end of the ornamental of the inner pipe and the rotating head of the screw cooperating with the nut is linked to a distance adjusting sleeve. The telescopic coupling link can be fixed between two walls without fixing the supporting seat and without destroying the integrity of the wall. As a result, the unfirm situation because the spring loses the elasticity can be avoided by omitting the spring and can be fixed between two walls freely. The structure of the telescopic coupling link is simple and the operation is convenient.
Description
Technical field
The utility model relates to the coupling technical field, especially relates to without other fastening pieces, can arbitrarily fix the coupling rod that is provided with across between two walls.
Background of invention
Across between two walls coupling rod being set, be used for hanging curtain, airing towel etc., usually need on two walls, to be provided with earlier the coupling rod fixed bearing, this will destroy the integrity of wall, the applicant applied for once that a key name was called the utility model patent of " tension type stretch coupling rod ", application number: 200520115742.5, be in pipe, to establish spring, withstand with the tension force of spring and between two walls, to locate, this flexible coupling rod can be self-align preferably, do not need other bearings and fastening piece, but use spring to follow the string for a long time, influence the soundness that coupling rod is located between two walls.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to provide a kind of without spring, do not need fixed bearing, and simple in structure, easy for installation, can be with being intended to flexible coupling rod fixing between two walls.
For achieving the above object, the technical solution of the utility model is such: a kind of flexible coupling rod, and the pipe bar that has two calibers not wait connects together, and slippage mutually, is provided with sheathing at the two ends of socketed pipe; The conical screw that in socketed pipe, has a parafacies to cooperate, tapered cup nut, this conical screw is connected in the inner tube head, locate by the inner tubal wall punching press, and can rotate with inner tubal wall, the tapered cup nut that is combined together with conical screw is a untight circle ring, circle ring go up division ring lack outer also have two not on earth groove lack, ring lacks with groove and lacks on the circle peripheral wall respectively with 120 degree spaced apart, under free state, the tapered cup nut external diameter is slightly larger than outer tube diameter, need the pressing ring to lack and place in the outer tube, the tapered cup nut outer wall contacts connection with outer tube wall, when interior pipe clockwise rotates with respect to outer tube, conical screw and tapered cup nut screw, tapered cup nut is opened, and its outer wall is fitted with outer tube wall tightly, stops inner and outer pipes to relatively move; At nearly sheathing one end internal fixation one nut of interior pipe, the head that revolves of the screw that matches with this nut connects the roll adjustment cover, and the outer nearly sheathing place of pipe rotated the roll adjustment cover in roll adjustment was sheathed on, and screw screws or withdraw from motion.
During use, rotate the inner and outer pipes bar conical screw and nut are unclamped, pulling inner and outer pipes bar makes its length equate with the wall spacing, screws conical screw, nut, places between wall behind the mounting point, and rotation roll adjustment cover promptly can be fixed between two walls voluntarily.
If two wall spacings then need be changed specification in addition above inner and outer pipes pole length sum in the coupling rod.
Owing to adopted technique scheme, a kind of flexible coupling rod of the present utility model, do not need fixed bearing, can directly be fixed between two walls, not destroy the integrity of wall, because of its without spring, can avoid producing unstable phenomenon because of permanent use spring follows the string, and simple in structure, easy to use, can be fixing with being intended between two walls.

Embodiment
By Fig. 1---shown in Figure 5, a kind of flexible coupling rod of the present utility model, the inner and outer pipes bar 3,7 that has two calibers not wait connects together, and slippage mutually, is provided with sheathing 1 at the two ends of socketed pipe; One secondary taper bolt 6 is arranged in socketed pipe, the conical screw of this taper bolt is connected in the inner tube head, locate by the inner tubal wall punching press, and can rotate with inner tubal wall, the tapered cup nut that is combined together with conical screw is a untight circle ring, circle ring go up division ring lack 9 outer also have two not on earth groove lack 10,11, ring lacks with groove and lacks on the circle peripheral wall respectively with 120 degree spaced apart, under free state, the tapered cup nut external diameter is slightly larger than outer tube diameter, need the pressing ring to lack and place in the outer tube, the tapered cup nut outer wall contacts connection with outer tube wall, when interior pipe clockwise rotates with respect to outer tube, conical screw and tapered cup nut screw, tapered cup nut is opened, and its outer wall is fitted with outer tube wall tightly, stops inner and outer pipes to relatively move; At the nearly sheathing one end internal fixation one nut (not shown) of interior pipe, the head that revolves of the screw that matches with this nut connects roll adjustment cover 2, and the outer nearly sheathing place of pipe rotated the roll adjustment cover in roll adjustment was sheathed on, and screw screws or withdraw from motion, and is long with adjustable lever;
Outer wall of inner tube is damaged when preventing to spur inner and outer pipes, establish a protecting jacket 4 of making by soft material at the inner and outer pipes junction point;
End at the outer tube bar has a restraining groove 5, in case interior pipe bar is pulled away from out the outer tube bar;
