The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment one: in conjunction with Fig. 1, shown in Figure 7, opening and closing umbrella device of the present utility model mainly is to be made of assemblings such as column 5, interior pipe 8, pull bar 1, knob 3, sliding shoe 2, rotating shaft 4 and latch segments 6.The upper end and the umbrella nest 7 of pipe 8 fix wherein, and slidable fit is in column 5, the long chute 51 of one open-type is all arranged on both length directions, be used for installing the sliding shoe and the pull bar that can slide up and down within it, pull bar 1 is contained in the column 5, and its upper end links together with screw and interior pipe 8, the metal insert thread connection in lower end and the sliding shoe 2, sliding shoe drives the motion of umbrella nest by the transmission of this pull bar like this, and reaches the purpose of the folding of umbrella.

Sliding shoe 2 is contained on the column 5, can slide up and down.Wherein be provided with an axis hole, be used for assembling rotating shaft 4 in the roughly middle part of sliding shoe 2.One of axis hole has a square hole 21, is used for assembling latch segment 6.Be positioned on the sliding shoe of square hole both sides and also be respectively equipped with an I-shaped groove, a side of groove has the boss 22 suitable with the column chute, and boss 22 is inserted in the chute 51 of column, and and the column inwall between the end face of the locking of can fitting is mutually arranged.

Knob 3 is contained on the sliding shoe 2, can rotate relative to sliding shoe.This knob 3 outside triangular in shape, there is a cylindrical boss inside, and a dimple in this boss and the sliding shoe outside is rotatably assorted and reaches the purpose of axial limiting.Described knob and sliding shoe i.e. the cooperating and be connected together by the rotating shaft that runs through both axis holes of dimple by between the two and boss.

One of rotating shaft 4 is shaped on screw thread, and metal insert 61 threaded engagement with in the latch segment have a step 41 and be positioned at the thread segment rear portion, and the outer face of this step can fit with the end face on the sliding shoe; The other end of rotating shaft 4 is made square, cooperates with square opening on the knob and reaches radial location.During assembling, rotating shaft 4, can be rotated with knob 3 by being connected together with screw and knob 3 behind axis hole on the sliding shoe and the square opening on the knob from an insertion of sliding shoe square hole 21.

Latch segment 6 is arranged in the square hole 21 of sliding shoe, and thread connection is in rotating shaft 4, because the square hole 21 of latch segment 6 and sliding shoe is for being slidingly matched, so this latch segment 6 is being made axial translation under the drive of rotating shaft 4 in square hole 21.

By this opening and closing umbrella device that above-mentioned member constitutes, when assembling, as long as be connected upper connecting rod 1 with rotating shaft 4, latch segment 6, knob 3 and after sliding shoe 2 is assembled into one, integral body is inserted in the column 5, is connected with interior pipe 8 usefulness screws to get final product again, and it is quite convenient to assemble.

Can close one's umbrella like a cork and parachute-opening by this device, when wanting parachute-opening,, drive pull bars 1 by sliding shoe 2 and move downward as long as spur sliding shoe 2 downwards, by pipe 8 and umbrella nest 7 in pull bar 1 drive umbrella stand is launched again, be rotated in the forward knob 3 this moment again is locked on the residing stud sliding shoe 2.Specifically: forward rotation knob 3, driving rotating shaft 4 by knob 3 rotates, drive with the latch segment 6 of its bolt by rotating shaft 4 again and do translation forward, when latch segment 6 moves to when contacting with the column inwall, step 41 in the rotating shaft also contacts with end face on the sliding shoe 2, so being rotated further along with knob 3, step 41 in latch segment 6 and the rotating shaft presses corresponding column inwall and sliding shoe end face, sliding shoe is outwards moved owing to the effect of step, and the boss 22 that moves on the sliding shoe presses the column inwall, and this moment, sliding shoe 2 was promptly located lock-out state (as Fig. 3 with column 5, shown in Figure 4).Because sliding shoe 2 can be positioned on the optional position of column 5, thereby can make umbrella cover that different start points is arranged.

During if will close one's umbrella, as long as backward rotation knob 3, make latch segment 6 do translation backward by rotating shaft 4, and when latch segment backward after the translation, end face on it all in succession separates (as shown in Figure 1 and Figure 2) with the end face of sliding shoe and the boss of sliding shoe with the column inwall with the step of column inwall, rotating shaft, upwards promote sliding shoe 2 this moment, drive the umbrella nest by sliding shoe 2 by pull bar 1 umbrella stand is folded.

Embodiment two: as Fig. 5, shown in Figure 6, what it was different with embodiment one is the mode that has adopted a kind of Camlock, and relative embodiment one is more simple for its structure.Specifically be that a end in rotating shaft 4 is integrally formed with an eccentric wheel 42, this eccentric wheel 42 is positioned at the square hole of sliding shoe, can rotate in square hole with rotating shaft 4.

Its operation principle is as follows: when knob 3 rotated, also along with rotating together, when turning to certain position, the end face of eccentric wheel 42 compressed the inwall of column 5 one sides for axle 4 and eccentric wheel 42, made sliding shoe 2 fixing.When counter-rotating knob 3, the end face of eccentric wheel 42 separates with column 5 inwalls, and sliding shoe 2 can freely slide up and down.The knob 3 that can reverse in addition, the eccentric wheel 42 on the axle compresses the inwall of column 5 opposite sides, and sliding shoe 2 is fixed.

Except the described structure of above-mentioned two embodiment, the utility model can also have other constructional variant, and does not break away from scope of the present utility model.For example except the structure of above-mentioned latch segment locking and eccentric wheel locking, can also adopt mode as Fixed latches formula locking mechanism or the bloated locking mechanism of tapered side etc.
