[embodiment]
Below in conjunction with drawings and Examples, movable telescopic arm assembly involved in the present invention is described in detail.
Please refer to accompanying drawing 1, illustrated therein is movable telescopic arm assembly 100, the main body of this movable telescopic arm comprises outer arm 10 and interior arm 20, and this outer arm 10 is hollow structure, and interior arm 20 is nested in outer arm, and sliding type extends outside outer arm or is contracted in outer arm. The effect that can realize is when opening completely, and the length of interior arm 20 is connected the length extending outer arm 10, and when folding is retracted, and interior arm 20 main body is overlapped outside in arm 10 completely, and entirety only embodies the length of outer arm 10.
This outer arm 10 and interior arm 20 are long shape, this outer arm 10 has outer arm headend and outer arm coupling end, interior arm 20 has interior arm tail end and interior arm coupling end, outer arm coupling end and interior arm coupling end activity are engaged togather, and are in fact that outer arm coupling end is inserted in outer arm coupling end, and are provided with one pair of damping wheel 50 at interior arm coupling end place, damping wheel 50 drives interior arm along outer arm internal slide, when this interior arm skids off maximum position, outer arm coupling end can be stuck in, it is unlikely to slippage out.
Outside arm and interior arm need the row's of walking line 40, row's line 40 runs through telescopic boom and the carrier of conducted signal, row's line 40 needs to extend to interior arm tail end from outer arm headend, and in order to the outer arm relative movement of the internal arm of needs carries out keeping away position, can not be stuck in the slip of interior arm, also to be considered not excessively bending row line 40 simultaneously during the row's of layout line 40, avoid frequent bending and strain. So one end of row's line 40 is connected to outer arm headend inside, and the other one end arranging line 40 is connected to interior arm tail end inside.
Conventional way, just meets telescopic boom by length, and row's line 40 of flexible maximum length installs in outer arm and interior arm, freely places, and this kind of mode may the arm problem that arm stretches and moves outward in the row's of generation line 40 Position disturbance.
And the present invention, a supporting plate 30 has been established outside in arm, the junction of this supporting plate 30 row of being arranged on line 40 and outer arm 10, play fixed part row's line 40, the row's of picking-up line 40, and when interior arm slides, the row's of guiding line 40 is followed interior arm movement tendency and is moved, the row's of making line 40 can not disturb machinery component movement, also can not be pressed from both sides by mechanical part card, or damages.
To should the position of supporting plate and size, there is a supporting plate groove 21 in interior arm 20, when interior arm 20 contract completely hold together in outer arm 10 time, supporting plate 30 is just inserted in supporting plate groove 21. This supporting plate, in " L " type, is made up of a horizontal stripe position and vertical bar position, comprises bottom surface and end face, and this supporting plate is connected with outer arm headend with the vertical bar position of " L " type. Row's line connects up along supporting plate, according to the wiring situation of row's line, can arranging line whole section and be divided into three sections, row's line is fixed into the first fixing section along supporting plate, row's line is the 2nd fixing section along the part that supporting plate groove bottom is fixing, and is free segment between the first fixing section and the 2nd fixing section.
First fixing section 41 is fixed from the inner end face along the end face-horizontal stripe position at supporting plate 30 vertical bar position of outer arm headend, is turned to bottom surface from the end face at horizontal stripe position; 2nd fixing section 43 is all fixing from interior arm tail end to interior arm coupling end, is fixed on supporting plate groove bottom, and free segment freely is engaged between two sections.
Between two damping wheels 50, the row's of correspond to line position is provided with an elastic pressuring plate 60, on the row's of being pressed in line. This elastic pressuring plate 60 can the row's of press against line be allowed to condition at supporting plate insert time, supporting plate groove can not be squeezed into conveniently, but along side, supporting plate groove vertical bar position clearance spaces keep away position make a concession. And when interior arm outwards stretches out, row's line is stretched along the traction of interior arm in an orderly manner and stretchs out steadily.
The present invention is by supporting plate, and support guides row's line, is divided into three sections be fixed respectively and be free to slide design on row line, it is possible in ensureing, arm and outer arm relatively sliding are smooth and easy and interference-free, arrange line stable signal transmission high speed. Supporting plate slides in interior arm along interior arm supporting plate groove, and the row's of guiding line is followed interior arm and moved, and in also avoiding inside and outside arm to move fast, friction and Extrusion is to arranging line and the row's of making line easily ruptures and affects product work-ing life simultaneously.
The above, it it is only the better embodiment of the present invention, not the present invention is done any restriction in form, although the present invention discloses as above with better embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when utilizing the technology contents of above-mentioned announcement or it is modified to the equivalent embodiment of equivalent variations, in every case it is do not depart from technical solution of the present invention content, the any simple modification above embodiment done is referred to according to the technology of the present invention, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
