Further, the axis perpendicular of a diagonal line and connecting tube of the parallelogram mechanism of the bulge is put down
The top and bottom of row quadrangular mechanism are equipped with compressing member, and when bulge opens, compressing member is tightly attached to the pipeline of connected tube
On inner wall, when bulge closes up, compressing member leaves the inner wall of the pipe of connected tube.
Further, the rotating member includes driving link and two driven members, and two driven members are located at driving link both sides, two from
The axis of moving part overlaps, and the axis of the driving link and the axis of two driven members are mutually perpendicular to, two driven members be respectively from
Moving part one and driven member two.
Further, the driving link be drive bevel gear, the driven member be driven wheel of differential, and drive bevel gear and from
Dynamic bevel gear is intermeshed, and is rotated by drive bevel gear, the driven wheel of differential of both sides is driven to rotate.
Further, the driven member is connected with driving member, and the driving member and driven member axis overlap, and are transported by driven member
It is dynamic, and then drive drive member；The driving member includes driving member one and driving member two, the driving member one and driven member one
It is connected, the driving member two is connected with driven member two.
Further, the driving member is leading screw, a diagonal line and the transmission of the parallelogram mechanism of the bulge
The axis of part coincides, and two hinge joints of double leval jib are overlapped with driving member, and two hinge joints are connect by sliding shoe with driving member,
It is slided on driving member by sliding shoe, realizes that bulge opens or closes up.
Further, the driving member is fixed by the holder in connecting tube, and the holder includes rack body and axis
One is held, bearing one is mounted on rack body, and the driving member is installed with the cooperation of bearing one, and rack body is equipped with cable hole.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. the conduit coupling of the present invention is attached using the frictional force of the inner wall of the pipe of expansion mechanism and connected tube, no
Lug boss can be formed outside connected tube, do not interfere with the beauty of entire furniture；
2. the present invention connector using expansion mechanism opening or close up, realize the connection and dismounting of connected tube, Ke Yiyong
It is connected in the pipeline of a variety of calibers, it is when in use, more convenient flexible.
