Abstract

The invention relates to an inflatable umbrella which is capable of pumping air into a hollow supporting rod to expand the supporting rod so as to spread the umbrella surface. Inner holes of the supporting rod are all communicated with inner holes of an inflating pump, a main one-way valve is arranged below the communicating part of the inner holes of the supporting rod and the inner holes of the inflating pump, the upper end of an inflating rod is provided with a sealing ring, and the upper port of the inner hole of the inflating rod is provided with a main exhaust cone; the upper end of a handle is communicated with the lower end of the inflating rod, an auxiliary one-way valve is arranged in the handle; and the upper end of a switch knob is screwed with the threads at the lower end of the handle, and an auxiliary exhaust cone is arranged at the upper port of the through hole of the switch knob. When the umbrella is opened, the auxiliary exhaust cone is separated from the auxiliary one-way valve, air is pumped into the inner holes of the supporting rod through the inflating pump and the inflating rod, and the supporting rod is expanded for extending under the control of the main one-way valve to spread the umbrella surface. When the umbrella is closed, the auxiliary exhaust cone is ejected upwards to open the auxiliary one-way valve, the inflating rod is upwards pushed, and the main exhaust cone ejects to open the main one-way valve, therefore, air in the inner holes of the supporting rod can be exhausted.

Description

The inflatable umbrella

Technical field

The present invention relates to a kind of umbrella, thereby especially can make the strut expansion stretch the inflatable umbrella that struts umbrella cover through in the strut of hollow, pumping into air.

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, the deficiency of in use damaging easily; The present invention provides a kind of inflatable umbrella; Thereby this inflatable umbrella can make strut expansion stretching, extension strut umbrella cover through in the strut of hollow, pumping into air, and simple in structure, not fragile.

The technical solution adopted for the present invention to solve the technical problems is: the present invention includes 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 port of inflator is through the top cover sealing.In inflator, main check valve is arranged on the strut endoporus is communicated with the place with the inflator endoporus below, and 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 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, offers through hole at the axial line of switching knob; 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, in the endoporus of strut, pumps into air through inflator and inflating rod 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 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 in proper order.

The invention has the beneficial effects as follows, thereby can make strut expansion stretching, extension strut umbrella cover through in the strut of hollow, pumping into air, 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 port of inflator 3 is through 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, and 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 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, offers through hole at the axial line of switching knob 7; 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; In the endoporus of strut 1, pump into air through inflator 3 and inflating rod 8 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, get final product thereby air order in strut 1 endoporus is discharged via the through hole 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.
