During locking, rotational lock handle, so that retaining ring is displaced outwardly along ratchet wheel sliding ring, to make up due to cutting spacing
The space existing and being formed between ratchet mechanism and connecting rod aligning guide, coupling mechanism force size is controlled, thus realizing reliable locking.
Operation principle
Present invention mainly solves three technical problems：One is to align principle using wedge shape, and design linkage makes leak stopping
Umbrella remains to quick aligning cut center in the case of the entrance of rapidly great deal running water, and two is real using the plug-type operation of ratchet mechanism
Show quick positioning at hull cut for the leaking stoppage umbrella, three is to finely tune operation by spiral to meet secure ratcs requirement.
The work process of the present invention is：
1. rounding state.When leaking stoppage umbrella does not work, mechanism is in rounding state, and connecting rod aligning guide folds and packs up, ratchet
Detent mechanism is located at runner position, and spiral retaining mechanism is in the state of back-out.
2. align positioning states.With hand propelled ratchet wheel positioning mechanism quick sliding forward, end in contact before ratchet wheel positioning mechanism
To connecting rod aligning guide rear slip ring when, connecting rod will be aligned and boost, make push rod formed the conical surface, be stuck in inside hull cut, make
Umbrella stem is maintained at cut center, realizes to orthofunction；Ratchet bar holds out against cutting under ratchet spring effect, and automatic reverse
Locking, realizes positioning function.
3. canopy deployed condition.When implementing leak stopping operation, cabin is stretched out along hull broken hole in the umbrella body front end of rounding state
Outward, open canopy, canopy strut slides hub drivening rod aligning guide forward slip, umbrella stem rides over broken hole inside circumference.
4. locking state.Rotational lock handle, makes retaining ring be displaced outwardly along ratchet wheel sliding ring, between making up due to cutting
Away from presence and the space that formed between ratchet mechanism and connecting rod aligning guide, realize reliable locking.
The above, be only presently preferred embodiments of the present invention, not the structure of the present invention is made any pro forma
Limit.Any simple modification, equivalent variations and modification that every technical spirit according to the present invention is made to above example, all
Still fall within the range of technical scheme.
