Description
Technical field
The invention discloses a kind of large-scale parasols folding structure, it belongs to daily living article manufacturing technology field.
Background technology
Large-scale parasols refers generally to the parasols of non-hand-held class, and its height is high, and umbrella cover is big, is mainly fixed on ground and uses.
The wind loading rating of large-scale parasols is by mainly there is umbrella shank, and umbrella post and umbrella frame determine that umbrella shank typically has many ironwares, cement, marble
And the class umbrella shank such as water filling.Umbrella post umbrella frame needs to have high intensity, and indeformable, rustless advantage has very strong wind resistance.
There is polytype large umbrella in the prior art, be umbrella cover the problem of the most obvious there is also many problems
Open and folding is more bothered, particularly when large umbrella height is higher, when umbrella cover is larger, individual is difficult opened and received
Folding operation, can cause a variety of inconvenience, meanwhile, umbrella rod structure is usually hollow straight pipe structure, and its wind resistance power and compressive property are not allowed
Easily improve, run into strong wind weather and easily snap off and cause security threat.
In terms of the opening and folding structure of large umbrella, patent CN102150982A discloses a kind of the big of lever principle
Type umbrella, includes：Umbrella shaft, interior middle rod, upper nest, middle nest, lower nest, long bone, support rib and gangbar；In described lower nest and umbrella
Rod is fixedly connected, middle nest and umbrella shaft pivot bush unit；It is located in described umbrella shaft on the position below lower nest and goes back pivot bush unit
There is a connecting seat, lower pull bar is also associated between connecting seat and middle nest, be provided with connecting seat and coordinate locking with umbrella shaft
Locking member.Its structure alleviates the active force in opening process, by the way of pull-down pattern parachute-opening is than traditional upward passage
Parachute-opening operates more laborsaving convenience；Parachute-opening or the active force closed one's umbrella needed for operating process are substantially impartial, so in parachute-opening
Or in umbrella-folding process strutted or draw in average rate, it is to avoid have influence on people or the thing of surrounding.
Patent CN2865384U discloses handful length multi-section stretching structure in a kind of large-scale parachute kit, including umbrella body part,
It is made up of middle handful, handle, movable honeycomb and branch umbrella frame unit；Middle handful at least includes two socket mobile jibs, in detent mechanism is formed
Hold in both hands the flexible and positioning of a length at least section；Movable honeycomb sets the inserted link of a tool catching groove；One operator includes a pedestal, operation
Component and resetting spring, pedestal have chamber part and cannula portion, and groove chamber part provides operating assembly and assembled with resetting spring and to work
Dynamic honeycomb acts and controls opening and closing umbrella；A branch of conjunction mechanism, including a cup and resetting spring movable set are in sleeve pipe, when closing one's umbrella
Passage cup, to collect bundle branch umbrella rib structure end pearl part or solution beam, realizes the adjustment of middle handful telescopic, the branch of large-scale parachute kit manually
Umbrella frame end beam, which is closed, will not scatter and open the control that closes one's umbrella.
Summarize apparently, the opening and folding structure of the medium-and-large-sized parasols of prior art are complicated, and component is more, once ask
Topic, which is difficult to safeguard, repairs, and needs many people to coordinate realization to open and folding behaviour when the higher umbrella cover width of umbrella pillar height degree is larger
Make, using above making troubles, and because umbrella post is generally hollow-core construction, there is also some problems for its wind resistance and stability.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of large-scale parasols folding structure, it is using worm screw and and snail
Wheel is engaged structure, and it is opening and the folding that umbrella cover can be achieved that rotating operation need to be only carried out in bottom handle, no matter the height of umbrella
And width, can a people complete umbrella cover open and folding operation, using easy to operate.
In order to achieve the above object, the present invention is adopted the technical scheme that：
A kind of large-scale parasols folding structure, including circular pedestal, umbrella frame, worm gear centre bore, handle, bearing, crank handle, transmission
Axle, nut, cross bar, worm gear, worm screw, pedestal straight trough, pedestal straight trough aperture, umbrella cover, screw, screw-type umbrella post, wherein, circular seat
Body is evenly distributed including six bar shaped pedestal Kuai Huan centers, and it is straight so as to limit six pedestals that it is circumferentially evenly spaced apart distribution
Groove, each bar shaped pedestal block section is in concave, and each pedestal straight trough, which can be accommodated respectively, is provided with a umbrella frame, one end of umbrella frame
Equipped with semicircle worm gear, semicircle worm gear has a centre bore, and it passes through pin with the pedestal straight trough aperture on pedestal straight trough
It is combined together, umbrella frame can be rotated freely in pedestal straight trough after assembling, worm screw is additionally provided with inside circular seat body, worm screw is led to
Cross and be fixed on along the bearing at its axial two ends on circular pedestal, worm screw can realize that power is passed with the intermeshing cooperation of semicircle worm gear
Pass.
One of importance as the present invention, the power transmission shaft is solid material structure.
One of importance as the present invention, in use, whole umbrella body is disposed vertically, fix tightly on base
Lean on, counterclockwise swinging handle so that power transmission shaft drives worm screw to rotate, and worm screw is by driving all worm gears on umbrella frame to rotate
The opening of umbrella frame is realized, until umbrella frame and the perpendicular angle of umbrella post so that whole umbrella cover opens expansion completely.On the contrary, clockwise
Swinging handle is rotated, power transmission shaft reversely drives worm screw to rotate, worm screw realizes umbrella frame by driving all worm gears on umbrella frame to rotate
Folding, until umbrella frame is parallel to each other with umbrella post, realize the complete folding of whole umbrella cover.
