Description

Inflatable cotlapsible umbrella

The utility model relates to the collapsible en-toutcas of a kind of inflatable.

At present, commercially available en-toutcas generally has two kinds of forms.A kind of is the umbrella of old-fashioned steel umbrella frame, and another kind is the umbrella that adopts the collapsible umbrella frame of steel.The former volume is bigger, carry, use and collect not too convenient.The latter not only needs to consume clearly more steel, and its structure more complicated, and is fragile, and the life-span is short, and cost is than higher.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and long, the easy to use collapsible en-toutcas of inflatable of a kind of simple in structure, handsome in appearance, life-span is provided.

How introduce the purpose of this utility model below in conjunction with accompanying drawing realizes.

According to shown in Figure 1, the utility model comprises umbrella cover and umbrella handle. It is essentially working of plastics. Web face 2 at the umbrella cover is provided with pneumatic tyre umbrella frame 1. Wherein the middle part of web face 2 and edge are two annular pneumatic tyres, Between two annular pneumatic tyres, have many radially pneumatic tyre be connected with annular pneumatic tyre by intercommunicating pore. On pneumatic tyre umbrella frame 1, also be provided with vent plug seat 3 and vent plug 4, can take out vent plug 4 when stopping using and make it venting. The outside of umbrella handle is a loop bar 20, is disposed with handle body 19, handle bar 18 in it. Be provided with retaining spring 21 by pin 22 in the groove between handle body 19 and loop bar 20. Be provided with handle seat 24 in the bottom of umbrella handle, by a taper bolt 23 itself and loop bar 20 and handle bar 18 joined. In the button 12 on umbrella handle top, be provided with charge valve and piston from top to bottom, the two and telescopic umbrella handle form inflation mechanism jointly. The top of umbrella handle button 12 reaches circumferentially and pneumatic tyre umbrella frame 1 joins, and radially pore d is arranged₁Communicate. Above the concrete structure of said charge valve be: the middle part is a bolt 7, is disposed with inflation valve block 6, skin valve 10, charging valve 11, nut 5 on it from top to bottom, also is provided with gland 16 between inflation valve block 6 and skin valve 10 and bolt 7. Above the concrete structure of said piston be: the middle part is a bolt that links to each other with handle bar 18, is disposed with nut 5, piston valve 14, leather cup 15, piston valve 17 on it from top to bottom, is provided with gland 16 between piston valve 14 and leather cup 15 and bolt. (note: the nut 5 in charge valve and the piston and the specifications and models of gland 16 are respectively identical, so their label is respectively identical). Top edge at piston also is provided with gasket seal 13.

The manipulation process of opening and folding of the present utility model is as follows: telescopic umbrella handle has the function of inflator concurrently, at first vent plug 4 is pressed into vent plug seat 3, then the spiral shell tailspin of handle seat 24 from handle body 19 gone out, make it to move back and forth with manpower, air is squeezed in the pneumatic tyre umbrella frame 1, drive web face 2 and unfold, the umbrella cover opens thereupon. When the umbrella cover opens when reaching design and being suitable for state, then handle bar 18 is pulled out to stop position, and retaining spring 21 ejects from loop bar 20, and handle bar 18 at piston valve 17 and only Move under the two-way stop of spring 21, umbrella handle then is fixed on the longest position, and en-toutcas reaches open configuration. When vent plug 3 was extracted from vent plug seat 4, pneumatic tyre umbrella frame 1 will be exitted, and is pressed in the groove of handle body 19 with handgrip retaining spring 21 again. Shrink handle bar 18, loop bar 20 is pressed on retaining spring 21 in the groove, and to handle seat 24 screw-in handle bodies 19 spiral shell tails, umbrella handle is retracted to the shortest, and the umbrella cover then is collapsible into storage configuration. Movement relation in the gas replenishment process between the parts such as piston and charge valve is: when handle bar 18 is pulled out, when piston outwards moved, formed space A volume strengthened between piston and the charge valve, thereby produces certain vacuum. Skin valve 10 is pressed on skin valve 10 on button 12 inner circles and the charging valve 11 at its top atmospheric pressure or be higher than under the effect of atmospheric pressure in the charge valve, makes the sealing of pneumatic tyre umbrella frame 1 inner space. Meanwhile, under the atmospheric pressure effect, the leather cup 15 in the piston breaks away from piston valve 17. Slit and six aperture ds of leather cup 15, the hole slot b of piston valve 14 of air between piston valve 17 and handle body 19 enters space A, and it is communicated with atmosphere. This is the breathing process of inflator umbrella handle. When 18 contractions of handle bar, when piston was made drawback movement, space A volume reduced, and air is compressed, and air pressure is higher than atmospheric pressure, makes leather cup 15 be pressed on handle body 19 inwalls and the piston valve 17 space A and atmospheric isolation. Meanwhile, the gas push of the space A that skin valve 10 is compressed continuously, skin valve 10 is thrown off with charging valve 11, and gas is from six aperture d of the slit between charging valve 11 and the button 12 and skin valve 10, slotted eye b, the hole d of button 12 of inflation valve block 6₁Enter pneumatic tyre umbrella frame 1. It more than is the process of inflating of inflator umbrella handle. Under the reciprocating motion of handle bar 18, umbrella handle forms air-breathing and inflates process, thereby finishes the gas replenishment process of pneumatic tyre umbrella frame.

The utility model compared with prior art has lot of advantages.It simple in structure, handsome in appearance, light durable, cost is low, carries, uses and collect all very convenient.

Enforcement ratio of the present utility model is easier to.Major part is a working of plastics, and all factories with general plastic molding equipment and machined ability can make.Whole umbrella cover adopts Polypropylence Sheet to make, and wherein pneumatic tyre umbrella frame 1 also can be made of elastomeric material.According to the moulding of umbrella cover, the heat seal of design specialized or bonding mould can moulding, are convenient to pipelining production in enormous quantities.The umbrella cover can constitute various moulding with the design form variation of pneumatic tyre umbrella frame 1 and web face 2.Bulb nut 9 above the top compress gasket 8 that umbrella handle engages with the umbrella cover, and the nut in the umbrella handle 5, retaining spring 21, five kinds of seven findings such as pin 22, taper bolt 23 adopt A ₃, No. 45 steels do.
