Description

Inflating closer

Affiliated technical field

The present invention relates to a kind of inflation closing device, be that a kind of volume exquisiteness, performance of utilizing elastic plastic material to make inflated the closure techniques scheme efficiently, the product that forms can be widely used in gas compression containers such as sport ball, motion air cushion, automobile tire, airship air bag, anti-collision air bag, floating lifesaving, children toys.

Background technique

At present, some known inflation closing devices are made up of parts such as sleeve pipe, piston, springs as the automobile tyre inflation closer, when inflation finished, spring promoted piston roof pressure air-filled pore and finishes the inflation closing course, has certain blocking-up gas leakage function; But the structure relative complex, volume is bigger, and using scope is subjected to certain limitation; The known inflation closing device of in addition some such as children's inflatable toys, then be to form by inflation inlet and plastic cement plug two-part simply, the plastic cement plug is filled in toward inflation inlet one, just finish its inflation closing course, though structure is simple, but inflation effect and closure effect are extremely limited, hold at all and can't stand slightly bigger air pressure.

Summary of the invention

Purpose of the present invention, when keeping, optimizing general inflating closer tool blocking-up gas leakage function, improve, simplify utensil structure to greatest extent, with the specifically long-pending inferior limit that is reduced to of inflating closer, save manufacturing cost, and give its bigger usage space and using scope.

Principle of the present invention is: utilize the different decrements and different Young's modulus of different rubber materials, different materials is made the peripheral components and the central module of inflation utensil respectively; During inflation, central module retreats, and the gas passage space is expanded, vacateed to peripheral components; When closed, the central module sinciput, peripheral components tightens, the confining gas activity space, thus constitute complete inflation, the system of holding one's breath.

The present invention for realizing the technological scheme that principle is taked is: the air closer is divided into peripheral module and center module two-part; Peripheral module adopts elastomeric natural rubber manufacturing, is divided into air-filled pore, outer flap, interior flap, core, interior flap, gas-filling bag pipe, suction port and 6 parts of capsule tube cavity; Center module is made up of 1 parts of slide block, adopts high strength to have certain flexible urethane rubber manufacturing, directly inserts among the capsule tube cavity of peripheral module, and the piston slider as inflation is held one's breath forms inflating closer integral body jointly with peripheral module.

Compare with general inflating closer, product that the present invention forms can be obtained following beneficial effect:

1., simple in structure: the present invention only is made up of peripheral module and 2 parts of center module, and is simple in structure, can shorten the production time significantly, reduces product cost, energy saving;

2., the volume exquisiteness: the present invention forms the small product size exquisiteness, but 1 centimetre of hour volume less than can be widely used in the smart aeration vessel products of various high points, and application prospect is extensive;

3., safe in utilization, closed reliable: blocking-up gas leakage effect is apparently higher than other inflation closing device, and air pressure inside is high more, and closure effect is obvious more, and closure effect can keep more than 1 year.

In addition, the invention process is simple, makes simple and easyly, and formed product is solid durable, easy to use, and the market space is wide, has high surcharge.

Embodiment

The present invention, can specifically be implemented by the combination of corresponding module as a technological scheme.

Below, in conjunction with an embodiment and accompanying drawing, the invention will be further described:

Fig. 1 is that the solid of one embodiment of the invention is partly cutd open figure.

Among Fig. 1, inflating closer peripheral module and center module two-part are formed; Wherein: peripheral module is the main body part of whole inflating closer, comprises inflation inlet 1, core 2, interior flap 3, capsule pipe 4, suction port 5, capsule tube cavity 7 and outer flap 8 these seven parts; Center module is the core component of inflating closer, only 6 one parts of slide block.

The distribution rule of peripheral module each several part is: inflation inlet 1 is positioned at the central position of whole inflating closer, inwardly is communicated with capsule tube cavity 7 and suction port 5; Peripheral structure is followed successively by outer flap 8, core 2, interior flap 3 and capsule pipe 4; Though outer flap and interior flap are not of uniform size, the wing constitutes the closed sucker of two clamping aeration vessel inwalls, rigid blocking-up gas communication to relatively.

Fig. 2 is the main manufacturing dimension schematic representation of embodiment.

Among Fig. 2, main manufacturing dimension is benchmark with air closer height 9, and the manufacturing dimension except other position core, the air-filled pore forms ratio values with reference to air closer height 9, shown in the table specific as follows:

Closer height 9	Outer flap diameter 16	Interior flap diameter 17	Core diameter 15	Capsule pipe diameter 12	Capsule tube cavity diameter 11	Capsule tube cavity height 14	Slide block height 10	Suction port diameter 13
									H	0.67H	1.67H	0.27H	0.33H	0.17H	0.5H	0.33H	0.06H

Wherein, the slide block diameter equals capsule tube cavity diameter.

Fig. 3 is embodiment's a scheme of installation.

In the installation process of inflating closer, be coated with around the core among flap inside and outside the inflating closer earlier and spread certain bonding bulking agent, then according to the direction of Fig. 3 signal, inflating closer integral body 18 is imbedded the special position (as the ball navel) of container cyst wall 19, and the outer flap 8 that makes inflating closer is close to the aeration vessel cyst wall outside, interior flap 3 is close to aeration vessel cyst wall inboard, guarantee to form the seal junction of stopping gas communication between the two, thereby inflating closer correctly and securely is installed among the gas container.

Fig. 4 is the schematic representation of embodiment's gas replenishment process.

In gas replenishment process, Aerating needle 20 is inserted the closer air-filled pore, inwardly back down closer slide block 6 with inflation needle 21; When the gas atmosphere that charges into during, elastomeric capsule pipe 4 outside bulging greater than the air pressure of aeration vessel inside, 7 expansions of capsule tube cavity, the capsule tube wall breaks away from around the slide block 6, abdicates the space of gas communication; Simultaneously, have certain flexible slide block 6 afterbody pressurizeds and draw in, vacate bigger free air space, make to charge into gas and be able to therefrom smoothness and pass through, flow through suction port 5 and enter aeration vessel inside to the centre.

Fig. 5 is the closed blocking-up of an embodiment air-flow schematic representation

In Fig. 5, when inflation finished, because the air pressure of aeration vessel inside is greater than external pressure, capsule pipe 4 pressurizeds shrank to the centre, and the capsule tube wall is close to and is looped around around the slide block 6, makes the space that loses gas flow between the two; Simultaneously, the gas of internal tank high pressure enters capsule tube cavity 7 by suction port 5, promotes slide block 6 and outwards moves, and closer inflation inlet 1 is withstood in extruding, further blocks internal gas to external leakage; Therebetween, the air pressure of aeration vessel inside is big more, and the crowded subsides of 4 pairs of slide blocks 6 of capsule pipe are just tight more, and the sealing of 6 pairs of inflation inlets 1 of slide block is just tight more, thereby reaches the purpose of blocking gas communication fully.

The present invention can design the concrete shape and the specification of each module of inflating closer neatly according to actual conditions in implementation process, select the module material of different Young's modulus for use; By the organic assembling of various disparate modules, form multiple embodiments, thereby open product in different poses and with different expressions, bring up the vast market space.
