Description

The hydraulic pressure automatic umbrella folding and unfolding

The utility model relates to a kind of umbrella, particularly a kind of hydraulic pressure automatic umbrella folding and unfolding.

That generally uses at present unfolds umbrella certainly, must with the hands operate when folding, and this just causes the inconvenience of use.Having occurred multiplely now about the design of automatic umbrella folding and unfolding, but generally is to rely on the composite set of power spring to realize two-way self-act travel.This just makes the structure complicated of umbrella.Therefore not only improved manufacturing cost, and more fragile, inconvenience maintenance.

The purpose of this utility model is to overcome the prior art deficiency, use hydraulic transmission principle and theory of mechanisms theory and designed the full automatic umbrella that receipts are opened in a kind of single button control, not only simple in structure, easy to manufacture, and easy and simple to handle, reliable operation, make the profile of umbrella more become exquisite, attractive in appearance simultaneously.

The utility model comprises the handle of umbrella that umbrella bar, the umbrella frame with umbrella bar upper end phase configuration, the umbrella cover on the umbrella frame, umbrella bar lower end dispose.Its technical characterictic is: said handle of umbrella 5 has an inner chamber, configuration one compression spring 2 in the inner chamber, the top of compression spring 2 disposes a switch plunger 3, switch plunger 3 withstands on the interior top of moving turn-button 4, button 7 inclined-planes on down moving turn-button 4 and the handle of umbrella 5 are to top contact, button 7 and following moving turn-button 4 are slidingly matched by a groove and a slip protruding rail 6, said umbrella bar comprise one with the outer bar 8 of handle of umbrella 5 intracavity inter-connections, outer bar 8 inner sliding sleeves have the king-rod 9 that is connected with outer bar 8, king-rod 9 inner sliding sleeves have interior bar 10, the top of interior bar 10 disposes a umbrella head 13, and umbrella head 13 upper hinges have last umbrella frame 19 and middle umbrella frame 14, can following umbrella frame 17 be arranged hinge on the king-rod 9.Last umbrella frame 19, middle umbrella frame 14, down umbrella frame 17 all with outer umbrella frame 18 hinges, outer umbrella frame 18 and support bone 16 all with external support bone 15 hinges, the inner chamber of said handle of umbrella is filled with hydraulic oil for 5 li.Concrete structure is as follows:

(1) outer bar 8 is inserted in the handle of umbrella 5, king-rod 9 is placed in the outer bar 8, and interior bar 10 is placed in the king-rod 9.Fixing flange 12 on the king-rod 9.Umbrella head 13 is by the last top of bar 10 in being threadedly connected to.Following umbrella frame 17 is hinged on the flange 12, and middle umbrella frame 14, last umbrella frame 19 are articulated on the umbrella head 13.Following umbrella frame 17, middle umbrella frame 14, last umbrella frame 19 all are hinged with outer umbrella frame 18.Outer bar 8, king-rod 9 and interior bar 10 can relative motions.Handle of umbrella 5, outer bar 8 and king-rod 9 are made a connected chamber structure, and inject hydraulic oil in the chamber.

(2) button 7 all has groove with moving turn-button 4 inclined-planes down to top contact on following moving turn-button 4, the button 7, can be along moving on the slip protruding rail 6 times.Compression spring 2 withstands on down switch plunger 3 on the interior top of moving turn-button 4.Sliding cam 6 has defined the following final position of going up of time moving turn-button 4 motions.Repeating to press button 7 can make switch plunger realize a reciprocating stroke.

What (3) link to each other with slider component (umbrella head 13) in the utility model is to go up umbrella frame 19 and middle umbrella frame 14, and down umbrella frame 17 by the flange relative fixed on king-rod 9, whole umbrella frame frame is a kind of six bar structurals.

(4) on the piston head of switch plunger 3, movable king-rod 9, outer bar 10, adopt sealing ring, and add rubber blanket at oiling screw hole 1 place.

Fig. 7 is an A-A sectional view on Fig. 1, the 3rd, and switch plunger, the 4th, following moving turn-button, the 5th, handle of umbrella, the 6th, slip protruding rail, the 8th, outer bar.

Fig. 3 is the generalized section after the utility model parachute-opening.

Fig. 4 is a B TV structure enlarged drawing on Fig. 3, the 8th, and outer bar, the 9th, king-rod, the 10th, interior bar, the 12nd, flange, the 20th, sealing ring.

Be illustrated referring now to 1,2,3,4 pairs of operation principles of the present utility model of accompanying drawing.

One, parachute-opening process:

Figure 1 shows that the collapse state of umbrella.Compression spring 2 has only a small amount of precompressed, and buffer spring 11 is in free state.Press the button 7, switch plunger 3 promote hydraulic oil in the handle of umbrella chamber, flow to exumbrella bar 8 and in the tube chamber of umbrella bar 9, under the oil pressure effect, interior bar 10 is pushed out, along with the spacing of umbrella head 13 with flange 12 widens, following umbrella frame 14 increases with the angle of middle umbrella frame 18, and the umbrella frame frame is just slowly opened.Until the piston head of interior bar 10 is pulled to the interior top of king-rod 9, this moment, the umbrella frame frame was just opened fully.Along with button 7 continue press, the continuation of hydraulic oil is flowed, bar 10 goes out the inner chamber lira of king-rod from outer bar 8 in making, up to state shown in Figure 3, buffer spring 11 is depressed by the piston head of king-rod 9.Because button 7 is that the inclined-plane cooperates with following moving turn-button 4, just make 4 to produce the peripheral force that rotates around its axis, in case the groove of moving turn-

button

4 and 6 disengagings of slip protruding rail down, following moving button 4 just turns an angle, when release button 7, the lower end of sliding cam 6 just withstands on down ending in the groove of moving button 4.Umbrella has just been opened fully like this.

Two, the process that closes one's umbrella:

Press button 7 once more.When down moving turn-button 4 was pressed, because of contacting with button 7 inclined-planes, so will turn over a low-angle around its axis, when waiting release button 7, the groove of following moving turn-button 4 was by the oblique embedding part of slip protruding rail.The screen resilience of compression spring 2 makes that down moving turn-button 4 is chimeric fully with slip protruding rail 6, because 4 groove leads directly to, promotes to continue along sliding on the slip protruding rail 6, up to the interior top that button 7 is depressed into slip protruding rail 6 so be compressed spring 2.Hydraulic oil in this process is that the inner chamber from outer bar 8, king-rod 9 flows in the handle of umbrella chamber.Because sealing function, interior bar 10 will be pulled under oil pressure in the inner chamber of king-rod 9, and the reverse movement of umbrella stand when opening and slowly closed at this moment touches the last top of king-rod 9 up to the lower end of umbrella head 13.Along with the continuation backflow of hydraulic oil, the inner chamber of bar 8 in interior bar 10 will push back king-rod 9 is finally shown in Fig. 1 state.So far the process that closes one's umbrella finishes.

In the utility model, handle of umbrella 5 and following moving turn-button 4, button 7 usefulness duroplasts are made.Weight and cost have so just been reduced.Switch plunger 3 45 steel.Because sealing requirements can be overlapped the steel lining of a fineness in the big chamber of handle of umbrella, the good motion cooperation with assurance and switch plunger 3 has each bar of relative motion will guarantee higher axiality and cylindricity equally.
