Abstract

The utility model discloses an automatic folding and unfolding umbrella which is composed of an umbrella cover, an umbrella skeleton, an umbrella rod, a power spring, etc. The utility model is characterized in that an umbrella unfolding spring and an umbrella folding spring are added; the upper ends of the two components are connected with an umbrella top and the lower ends are connected with a lower rod sleeve and an upper rod sleeve; a dragging steel cable is arranged between an elastic clamp and a press key of the umbrella. When used, the umbrella can be automatically unfolded and moreover the umbrella cover can be automatically folded only by pressing the press key when the umbrella cover needs to be folded, bringing convenience for users.

Description

A kind of automatic opening-closing umbrella

The utility model belongs to a kind of parachute kit, but a kind of umbrella of auto-folder particularly.

Automatic folding umbrella is the parachute kit commonly used in people's daily life, but general automatic folding umbrella, no matter be two-fold or three folding just be automatic when opening, and the umbrella cover that can not close automatically.Therefore in use, when close umbrella cover and just often feel inconvenience need enter small space time of other article inconvenience both hands is arranged in people's hand.

The purpose of this utility model provide a kind of can the Automatic-opening umbrella face, and the automatic opening-closing umbrella of the umbrella cover that closes automatically.

The utility model purpose is realized by following technical scheme:

A kind of automatic opening-closing umbrella, it is except that comprising parts such as umbrella cover, umbrella frame, umbrella bar, power spring, elasticity card, handle, button, it also is provided with a parachute-opening spring and the spring that closes one's umbrella, wherein, the upper end of parachute-opening spring links to each other with the umbrella top, the lower end links to each other with the upper boom cover, and a tractive steel wire rope is housed between elasticity card and the button.

Above-mentioned automatic opening-closing umbrella, the described parachute-opening spring and the spring that closes one's umbrella are respectively extension spring and stage clip, and they all are sleeved on the upper umbrella rod, and the compression elasticity of the spring that closes one's umbrella is greater than the pulling force of parachute-opening spring.

Above-mentioned automatic opening-closing umbrella, described tractive steel wire rope is contained in the umbrella bar, and its upper end links to each other with the elasticity card, and umbrella bar lower end is stretched out in the lower end, is connected with button by connecting rod.

After adopting structure of the present utility model, not only can open automatically when parachute-opening, and when needs are regained umbrella cover, can press button, the spring that closes one's umbrella can promote the motion of upper and lower bar cover, umbrella cover is regained, thereby made things convenient for the user.

The utility model is known clearly fast below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of the utility model when regaining umbrella cover fully;

Fig. 2 is the structural representation of the utility model when opening umbrella cover;

View when Fig. 3 is the utility model withdrawal umbrella cover;

Fig. 4 is the utility model upper boom cover and low stem casing structural representation;

Fig. 5 is the utility model elasticity card structure schematic diagram.

Fig. 1 is the state diagram when not using, watch from the top down, compressing spring under the umbrella top, the top is the spring 1 that closes one's umbrella, last pole spring 2 compresses it, and the upper boom cover is held by elasticity card 3, is parachute-opening spring 4 in the right side extension spring of umbrella bar, be in the extension spring state this moment, its lower end links to each other with low stem casing 5, and low stem casing is hooked by button 6 this moment, and umbrella frame 7 all is in retracted state.Central authorities are tractive steel wire ropes 8 at the umbrella bar, and it is in relaxed state, and its end links to each other with button 6 by connecting rod 13.Number in the figure be 9,10,11 be respectively upper umbrella rod, lower umbrella rod and handle, power spring 12 is housed below upper umbrella rod, the power spring is compressed now.

Fig. 2 is automatic opening figure.When the user uses at needs, push button 6, then the low stem casing that hooks of button 5 is thrown off buttons, is pulled upwardly by parachute-opening spring 4, depresses elasticity card 3, is stuck in then between upper boom cover 2 and the elasticity card 3, and the umbrella frame 7 on the low stem casing opens, and umbrella cover opens.Meanwhile, button starts power spring 12 simultaneously, and upper umbrella rod is upwards ejected, and makes the umbrella bar be elongated to the operating position.After the umbrella bar elongation, the tractive steel wire rope of umbrella bar central authorities is strained thereupon, when the umbrella bar behind the operating position, the tractive steel wire rope should be strained fully, flexible surplus does not have.

Fig. 3 regains the umbrella cover state diagram.When needs are regained umbrella cover, press button again, button drivening rod 13, the tractive steel wire rope spurs the elasticity card 3 of upper end thereupon, shrinks in bar, and the upper boom cover 2 that is withstood by the elasticity card moves downward under the promotion of the spring 1 that closes one's umbrella, the compression stress of spring 1 requires the pulling force greater than parachute-opening spring 4 when design owing to close one's umbrella, therefore closing one's umbrella, spring can promote the upper boom cover, low stem casing moves downward together, is contained in the also withdrawal simultaneously of umbrella frame that upper and lower bar puts, and umbrella cover merges.When umbrella cover closed up, close one's umbrella spring 1 and power spring 12 all still were in extended configuration, and upper boom, lower beam also are in umbrella bar work extended position, therefore will return to the complete retracted state of Fig. 1, also needed the user manually to operate.User one holds low stem casing 5, and another hand propelled handle 11 makes spring 1 compression that closes one's umbrella, and parachute-opening spring 4 is elongated, and power spring 12 also is compressed simultaneously, when lower umbrella rod 10 moves upward to elasticity card 3, the elasticity card is compressed into upper umbrella rod 9, make upper boom cover 2 cross elasticity card 3, simultaneously below also stretch in the hook groove 14 of low stem casing by switch hook, unclamp low stem casing, lower umbrella rod 10 moves downward slightly, then upper boom cover 2 is blocked by elasticity card 3, and low stem casing 5 is hooked by switch hook, finishes the process of manual reversion.

Figure 4 shows that the structure of upper boom cover 2 and low stem casing 5, the center of low stem casing 5 porose 15 can make the upper boom cover entangle, and there is a breach 19 lower end of upper boom cover 2, the steel disc 17 of elasticity card is blocked, on upper boom cover and the low stem casing umbrella frame is installed all, simplifies for structure is shown, above-mentioned umbrella frame does not all draw.

Fig. 5 is the structural representation of elasticity card 3.Elasticity card 3 is by steel wire 16 and steel disc 17 associatings, and their lower ends are fixed on the umbrella bar, and the upper end can be compressed and enter in the umbrella rod notch, and tractive steel wire rope 8 is connected with steel wire 16 by rotating shaft 18.
