Abstract

Disclosed is an inflatable umbrella which is characterized in that hollow supporting ribs are expanded and stretched after being inflated with air so that an umbrella cover can be stretched. Inner holes of the supporting ribs are communicated with an inner hole of an inflating pump, a main check valve is arranged below junction of the inner holes of the supporting ribs and the inner hole of the inflating pump, a seal ring is arranged at the upper end of an inflating rod, and a main exhaust cone is arranged at the upper end opening of the inner hole of the inflating rod. The upper end of a handle is communicated with the lower end of the inflating rod, an auxiliary check valve is arranged in the handle, the upper end of a switch knob is in threaded connection to the lower end of the handle, and an auxiliary exhaust cone is arranged at the upper end of a through hole of the switch knob. When in opening of the umbrella, the auxiliary exhaust cone is separated from the auxiliary check valve, air is pumped into the inner holes of the supporting ribs by the aid of the inflating rod and the inflating pump, and the umbrella cover is opened after the supporting rods are expanded and stretched under control of the main check valve. When in closing of the umbrella, the auxiliary check valve is turned on by the auxiliary exhaust cone in a jacking manner, the inflating rod is then pushed upwards, and the main check valve is turned on by the main exhaust cone in a jacking manner, so that air in the inner holes of the supporting ribs is exhausted and the umbrella is closed.

Description

The inflatable umbrella

Technical field

The utility model relates to a kind of umbrella, thereby especially can make the strut expansion stretch the inflatable umbrella that struts umbrella cover by pump into air in the strut of hollow.

Background technology

At present, known umbrella complex structure, parts are various, therefore in use damage easily.

Summary of the invention

In order to overcome existing umbrella complex structure, parts are various, in use the deficiency of damaging easily, the utility model provides a kind of inflatable umbrella, thereby this inflatable umbrella can make strut expansion stretching, extension strut umbrella cover by pump into air in the strut of hollow, and simple in structure, not fragile.

The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises umbrella cover, strut, inflator, inflating rod, stop screw, limit sliding chutes, handle, switching knob, main check valve, secondary check valve, main exhaust awl, secondary exhaust cone, sealing ring and top cover.The strut of some hollows is arranged on the radius of umbrella cover uniformly, the inner end of each bar strut all is connected with the upper end of inflator, and the endoporus of each bar strut all is communicated with the endoporus of inflator, and the other end of each bar strut endoporus all seals, and the endoporus upper port of inflator is sealed by top cover.In inflator, main check valve is arranged on the strut endoporus is communicated with the place with the inflator endoporus below, insert in the inflator upper end of inflating rod, inflating rod is a hollow structure, be provided with the several sealed ring in the upper end of inflating rod, be provided with the main exhaust awl in the upper port of inflating rod endoporus, the main exhaust awl be positioned at main check valve under, on the bar wall of inflating rod, be vertically arranged with limit sliding chutes, be provided with stop screw in the lower end of inflator.Handle is a hollow structure, the upper end of handle is communicated with the lower end of inflating rod, in handle, be provided with secondary check valve, the upper end of switching knob is threaded with the lower end of handle, axial line at switching knob offers through hole, upper port at through hole is provided with secondary exhaust cone, secondary exhaust cone be positioned at secondary check valve under.During parachute-opening, the rotary switch knob makes secondary exhaust cone separate with secondary check valve, pumps into air by inflator and inflating rod in the endoporus of strut again, and under the control of main check valve, stretching, extension struts umbrella cover thereby strut expands.When closing one's umbrella, the rotary switch knob, make secondary exhaust cone upwards back down secondary check valve, upwards promote inflating rod again, and make the main exhaust vertex of a cone open main check valve, thereby the air in the strut endoporus is got final product in proper order via the through hole discharge of main check valve, inflator endoporus, main exhaust awl, inflating rod endoporus, secondary check valve, secondary exhaust cone and switching knob.

The beneficial effects of the utility model are, thereby can strut be expanded stretch and strut umbrella cover by pump into air in the strut of hollow, and simple in structure, not fragile.

The specific embodiment

In Fig. 1, Fig. 2, Fig. 3, the strut 1 of some hollows is arranged on the radius of umbrella cover 2 uniformly, the inner end of each bar strut 1 all is connected with the upper end of inflator 3, and the endoporus of each bar strut 1 all is communicated with the endoporus of inflator 3, and the other end of each bar strut 1 endoporus all seals, and the endoporus upper port of inflator 3 is by top cover 9 sealings.In inflator 3, main check valve 10 is arranged on strut 1 endoporus is communicated with the place with inflator 3 endoporus below, insert in the inflator 3 upper end of inflating rod 8, inflating rod 8 is a hollow structure, be provided with several sealed ring 14 in the upper end of inflating rod 8, be provided with main exhaust awl 11 in the upper port of inflating rod 8 endoporus, main exhaust awl 11 be positioned at main check valve 10 under, on the bar wall of inflating rod 8, be vertically arranged with limit sliding chutes 5, be provided with stop screw 4 in the lower end of inflator 3.Handle 6 is a hollow structure, the upper end of handle 6 is communicated with the lower end of inflating rod 8, in handle 6, be provided with secondary check valve 12, the upper end of switching knob 7 is threaded with the lower end of handle 6, axial line at switching knob 7 offers through hole, upper port at through hole is provided with secondary exhaust cone 13, secondary exhaust cone 13 be positioned at secondary check valve 12 under.

In Fig. 1, Fig. 3, Fig. 4, Fig. 5, during parachute-opening, rotary switch knob 7, secondary exhaust cone 13 is separated with secondary check valve 12, pump into air by inflator 3 and inflating rod 8 in the endoporus of strut 1 again, under the control of main check valve 10, stretching, extension struts umbrella cover 2 thereby strut 1 expands.When closing one's umbrella, rotary switch knob 7, make secondary exhaust cone 13 upwards back down secondary check valve 12, upwards promote inflating rod 8 again, and make main exhaust awl 11 back down main check valve 10, thereby the air in strut 1 endoporus is got final product in proper order via the through hole discharge of main check valve 10, inflator 3 endoporus, main exhaust awl 11, inflating rod 8 endoporus, secondary check valve 12, secondary exhaust cone 13 and switching knob 7.
