Description
Technical field：
The utility model belongs to sports goods technical field, is related to a kind of children and uses unidirectional air valve, particularly one kind to give
Ball inflating is easy to the unidirectional air valve that children use, atmospheric pressure value reduction in spheroid when can effectively prevent from extracting air valve.
Background technology：
Sports have special mentation, and it can keep together people, can make one positive and dare to wound
Newly, it is one of scholastic important component, physical culture religion that can promote individual character, the formation of unique makings, therefore physical education
Educate can not only by force physique, increase one's knowledge, increase technical ability, prior one side is to allow the ideological and ethical standard of student to be cultivated and sent out
Exhibition.
Ball game is one of teaching sports item, can temper the technical performance of human body, while tempering human body
The coordination ability；The inflation ball game such as football, basketball, vollyball is the common shape in middle and primary schools' ball game teaching and daily routines
Formula, and this kind of sports goods is frequently necessary to inflation when in use, inflation is how many also to be required, and gas has lacked without elastic force, gas foot
Hit body again to ache very much and be not easy to control spheroid, in regulation game, have strict requirements, such as football again to pressure in ball
Air pressure must reach sea level be 0.6 to 1.1 atmospheric pressure；But, conventional pneumatic method is first with ball pin in spheroid
Inflate and be plugged on hole, then connect aerating device, can not can not be reached very little after requirement size too much when beating, need one
Hand presses ball, and quick on the other hand to extract ball pin, speed can bleed off the gas in ball very much slowly, it is difficult to reach standard pressure value；And
When quickly extracting ball pin, it is necessary to which very big finger gripping holding force, these are all difficult to hold and realize for children.Therefore,
Usually in use, generally helping to inflate by teacher or parent, and this is unfavorable for the Moral Culture in physical education, it is impossible to fully sharp
With the advantage of physical culture itself, strengthen the self-reliance of student, promote student health growth.Therefore, seek to design a kind of children's use
Unidirectional air valve, the setting activity ball valve in valve body when inflation is finished, passes through the sealing function between movable ball valve and half ball sealing
Prevent gas from leaking, the gas pressure in spheroid inner bag is maintained in defined specification, draw ring is set in valve body both sides, it is time saving
It is laborsaving, it is easy to children to pull out unidirectional air valve.
The content of the invention：
Goal of the invention of the present utility model is the shortcoming for overcoming prior art to exist, and proposes a kind of children of design with unidirectionally
Air valve, to overcome the gas leakage during air valve is extracted to make the defect that spheroid inner bag air pressure is reduced, solves existing plunger
It is not easy to the problem of children extract.
In order to realize foregoing invention purpose, the children that the utility model is related to use unidirectional air valve, and its agent structure includes
Tracheae, cone, gas outlet, valve body, ball valve chamber, movable ball valve, support fin, half ball sealing, docking valve, docking screw thread, air inlet
Mouth and draw ring；The length of metal hollow tubular construction tracheae is 30~60mm, and one end of tracheae is provided with cone with a slope, cone
Side wall be provided with the gas outlet of through-hole structure, the other end of tracheae is connected with the left part of valve body；Valve inner is provided with ball valve
Placement activity ball valve in chamber, ball valve chamber, the length and diameter of ball valve chamber are more than the diameter of movable ball valve, and movable ball valve can be in ball valve
Intracavitary is moved freely；The inwall of valve body left part provided with support fin, support fin block movable ball valve not with valve body left part
Inwall is fitted, so as to form air flue between the inwall and movable ball valve of valve body left part；It is hemispherical dome structure in valve body right part
Half ball sealing, when half ball sealing is in contact with movable ball valve, forms sealing structure between the two；Valve body right-hand member is docking valve, docking
The outlet of valve is docking screw thread, is easy to be connected with external inflation device；The center for docking valve is air inlet, air inlet
Diameter is less than the diameter of movable ball valve, and air inlet is connected with ball valve chamber, tracheae, gas outlet, forms air flue；On the outside of valve body left end
Draw ring is arranged with, is easy to children's finger to pass through and pull out air valve；The utility model is in use, the cone of tracheae is aligned
After being forced into after the air-filled pore of inflated ball body, then aerating device is connected with the docking screw thread on docking valve, started
Inflation, gas enters ball valve chamber from air inlet, and promotion activity ball valve is withstood on the support fin of valve body left part, and gas passes through valve
Air flue between the inwall of body left part and movable ball valve, into tracheae, the inner bag for treating inflated ball body is entered from gas outlet, air pressure is treated
When reaching desirable value, the gases at high pressure undocked in the aerating device on valve, inner bag enter ball by gas outlet and tracheae
Valve pocket, and promotion activity ball valve withstood on the inner surface of half ball sealing of valve body right part, the inner surface of half ball sealing and movable ball valve
Outer surface is in contact, and forms sealing structure between the two, prevents gas from being spilt from air inlet, so as to avoid the air pressure drop in inner bag
It is low, accordingly even when slowing down the speed for extracting air valve, do not result in the consequence of the air pressure reduction in inner bag yet；The lower inflation dress of dismounting
Postpone, two fingers pass through draw ring, and air valve is extracted, and complete inflation.
The utility model compared with prior art, the setting activity ball valve in valve body, shape between movable ball valve and half ball sealing
Into sealing structure, prevent gas from leaking, keep the gas pressure value in spheroid inner bag；In valve body both sides, draw ring, time saving province are set
Power, is easy to children to pull out unidirectional air valve；Its structure design is simple, is easy to operation, and easy to use, application environment is friendly.
