Description

A kind of automatic closing device of umbrella

Technical field

The utility model relates to the accessory field of parasols, relates in particular to a kind of automatic closing device of umbrella.

Background technology

Traditional parasols, the parachute-opening mode drives umbrella rope, pull bar by the parachute-opening crank, and hand push is realized parachute-opening, and there is the shortcoming that parachute-opening is loaded down with trivial details, speed is slow, the umbrella rope is disconnected easily in the mode of crank parachute-opening; The Chinese patent of my earlier application: a kind of closing device of umbrella (patent No.: ZL200420107976.0) with follow-up improved Chinese patent: a kind of closing device (patent No.: ZL200520116792.5) of umbrella, employing is different from traditional mode of operation, thereby drive the folding that the relative column slip of sliding shoe realizes umbrella by knob, this device is compared with traditional mode, intensity is good, operate light relatively, but when closing one's umbrella, last nest rises, the finished product height is increased, constant in the use arranged in the place of some limited space, and still needing manual operation, structure is relatively still comparatively complicated.

Summary of the invention

The utility model is to overcome above-mentioned weak point, and purpose is to provide a kind of automatic closing device of umbrella, and this device is established nitrogen spring in the middle rod of umbrella, realizes automatic deployment, operates lightly, simple in structure, has solved problems of the prior art.

The utility model achieves the above object by the following technical programs: a kind of automatic closing device of umbrella, comprise nest, middle nest, following nest, middle rod, excellent top during the last nest of umbrella is fixed on, the middle nest of umbrella and following nest all are set on the middle rod versatilely, connecting long bone on the last nest, long bone connects short bone, connecting fulcra on the middle nest, fulcra connect short bone, and short bone is connecting to descend nest, establishes air spring in middle rod, the tail end of air spring is provided with fixing plug, in the rod, the tailpiece of the piston rod of air spring was fixedlyed connected with the middle nest of umbrella during fixedly plug was fixed on, and was provided with on described nest down and held positioner tightly.

As preferably, the described positioner of holding tightly comprises down the nest garment bag, screws garment bag; Described nest garment bag down is fixed on down on the nest, screwing garment bag is set in down on the nest garment bag, some places that symmetry arranged on the following nest garment bag excircle because of wall thickness gradually thickening form outer lug boss, screwing some places inner convex platform that symmetry is arranged on the garment bag inner periphery, described outer lug boss and inner convex platform are corresponding matchingly to be provided with.

As preferably, some places outer lug boss is two places, and some places inner convex platform also is two places accordingly.

As preferably, during the fixedly plug of air spring is fixed on by stay in the rod.

As preferably, air spring is a nitrogen spring.

The beneficial effects of the utility model: the no crank of this device, umbrella rope, pull bar, the advantage of Yi Qian device is relatively: automatic deployment, simple in structure, easy to use, parts are few, cost is low relatively.

Fig. 5 is the A-A cutaway view of Fig. 4.

Among the figure: 1-umbrella crown, the last nest of 2-, nest among the 3-, nest garment bag among the 4-, 5-fulcra, 6-nitrogen spring, rod among the 7-, the fixing plug of 8-, nest under the 9-, nest garment bag under the 10-, 11-screws garment bag, the 12-short bone, 13-inner convex platform, 14-outer lug boss, 15-long bone, 16-stay.

The specific embodiment

The utility model is further elaborated by embodiment below in conjunction with accompanying drawing:

Embodiment 1: as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, last nest 2, middle nest 3, following nest 9, middle rod 7, excellent 7 tops during the last nest 2 of umbrella is fixed on, the middle nest 3 of umbrella and following nest 9 all are set on the middle rod 7 versatilely by middle nest garment bag 4 and following nest garment bag 10, connecting long bone 15 on the last nest 2, long bone 15 connects short bone 12, connecting fulcra 5 on the middle nest 3, fulcra 5 connect short bone 12, short bone 12 is connecting to descend nest 9, establishes nitrogen spring 6 in middle excellent 7, and the tail end of nitrogen spring 6 is provided with fixing plug 8, the fixedly plug of nitrogen spring is locked on the stay 16 by the locking sunk screw, thereby realizes being fixed in the middle rod 7; The tailpiece of the piston rod of nitrogen spring 6 is fixedlyed connected with the middle nest 3 of umbrella, offers an open slot on middle excellent 7 the length direction, is provided with a small boss on middle nest, and small boss is fastened on and is used for fixing nitrogen spring in the open slot; Be provided with on described following nest 9 and hold positioner tightly, the described positioner of holding tightly comprises following nest garment bag 10, screws garment bag 11; Described nest garment bag 10 down is fixed on down on the nest 9, screwing garment bag 11 is set in down on the nest garment bag 10, have on the following nest garment bag excircle symmetry about 1/4 circle in two places wall thickness gradually thickening form outer lug boss and drop radially, about 1 ~ 2mm, at the inner convex platform that screws about 1/5 circle in two places that symmetry is arranged on garment bag 11 inner peripherys, described outer lug boss and inner convex platform are corresponding matchingly to be provided with.

During concrete the use, the effect of holding positioner tightly is opening and closing umbrella location and serves as the handgrip that closes one's umbrella;

Hold the location operation principle tightly: when screwing garment bag and be rotated counterclockwise, inner convex platform is along nest garment bag outer lug boss rotation down, and nest garment bag outer lug boss belongs to open type down, thereby because the revolving force of rotation garment bag is held power tightly to middle rod effect, realizes positioning action.

The course of work: on this device, add cover cave catcher cloth and umbrella crown 1 after, be a spendable complete product.Under the situation that umbrella is folding, built-in nitrogen spring is compressed in the stroke bottom near extreme position, is in compression storage power state.Nest under the nest place locking knob location guarantees that umbrella is in umbrella closing state under utilizing this moment.Unscrew when the user will descend nest place locking knob, the nest nest direction that makes progress moved during nitrogen spring was freed one's minds and driven, according to forming structural relation, connecting fulcra on the middle nest, fulcra connect short bone, short bone drive down again nest up the nest direction move, strut the realization parachute-opening until umbrella cover.When closing one's umbrella, when axially spurring, the user screws garment bag downwards, according to above structural relation, pulling force will be exaggerated and act on the air spring piston rod, overcome in the gas compression stress piston rod to contract, and nest is downward in the drive, reach the extreme position that closes one's umbrella,, finish closing one's umbrella by the locking device locking positioning.

Above described be specific embodiment of the utility model and the know-why used; if comply with the change that conception of the present utility model is done; when the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, must belong to protection domain of the present utility model.
