Abstract
A rapid telescoping support pole, a photographic equipment, and a hiking pole having an operation driving member, a transverse driving wheel, and a vertical transmission wheel cooperating with said transverse driving wheel; the vertical transmission wheel driving multi-section inner tubes cooperatively to make the multi-stage outer tube conversion between a telescopic unlocked state and a telescopic locked state so as to achieve the rapid telescoping purpose. It has the advantages of rapid telescoping, extremely convenient use and movement, and simultaneous operation of upper and lower telescopic poles in one cooperating movement, therefore it has superior performance in terms of technology, practicality and economy.
Claims6
A rapid telescoping support pole comprising:
- an operation driving member,
- a transverse driving wheel,
- a vertical transmission wheel cooperating with the transverse driving wheel, and
- a multi-section inner tube having a first inner tube, a second inner tube, and a third inner tube, each of which has a twist-limiting chamber that cooperatively moves with the three aforementioned inner tubes to form a telescopic locking structure that drives a multi-stage outer tube to rotate;
- the telescopic locking structure comprises a telescopic guide strip provided on an inner wall of the outer tube and an inner sleeve that fits the telescopic guide strip, and the inner sleeve being provided with a guide slot, wherein the telescopic guide strip enters the guide slot to form a movable state;
- the vertical transmission wheel cooperatively drives the multi-section inner tube to convert the multi-stage outer tube between a telescopic unlocked state and a telescopic locked state.
