Description
Technical field
The utility model is related to a kind of basketballs, more particularly, to a kind of basketball with aerification function.
Background technology
Currently, the case where conventional basketball is easy to happen chronic leakage in use for some time；It is needed at this time using outer
The pump-up device set is inflated, but, people can not possibly carry inflator, air punch these devices, therefore when occurring
Basketball lose gas can not normal use when, can only bemoan one's inadequacy in the face of a great task, be unfavorable for nationwide fitness programs.
Invention content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide one kind to be inflated to basketball during playing basketball
Automatic inflating basketball.
What the purpose of this utility model was realized in：
A kind of automatic inflating basketball, the automatic inflating basketball includes spherical shell, fixed peace on the inner wall of the spherical shell
It is slided equipped with outer barrel, on the inner wall of the outer barrel and is provided with piston, an inner cylinder is interspersed in outer barrel, and the bottom of inner cylinder is fixed and connected
It is connected on piston, inner cylinder）Top be fixedly connected on spherical shell inner wall, and on spherical shell inflating port connection inner cylinder tube inner chamber body
And outside air, the inner wall of the outer barrel, the outer wall of inner cylinder and piston bottom surface constitute first chamber, the inner wall and piston bottom of outer barrel
Face constitutes second chamber, and breather check valve is provided on the inner cylinder barrel, which is connected to the tube inner chamber body of inner cylinder
And first chamber, and the one-way air inlet direction of breather check valve is from the tube inner chamber body of inner cylinder to first chamber, on the piston
The one-way air inlet direction for being provided with connection check valve, and being connected to check valve be from first chamber to second chamber, the outer barrel
Air inlet is provided on outer wall.
The inner wall junction of a kind of automatic inflating basketball of the utility model, the outer barrel and spherical shell is filled with silica gel, institute
The inner wall junction for stating inner cylinder and spherical shell is filled with silica gel.
Compared with prior art, the utility model has the beneficial effects that：
The utility model enables basketball to be inflated when playing；So that basketball be not in thanks to gas show
As.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of automatic inflating basketball of the utility model.
Wherein：
Spherical shell 1, outer barrel 2, inner cylinder 3, piston 4；
First chamber A, second chamber B；
Inflating port 1.1；
Air inlet 2.1；
Breather check valve 3.1；
It is connected to check valve 4.1.
Specific implementation mode
Referring to Fig. 1, the utility model is related to a kind of automatic inflating basketball, the automatic inflating basketball includes spherical shell 1,
It is installed with outer barrel 2 on the inner wall of the spherical shell 1, is slided on the inner wall of the outer barrel 2 and is provided with piston 4, an inner cylinder 3 is worn
It being inserted in outer barrel 2, and the bottom of inner cylinder 3 is fixedly connected on piston 4, the top of inner cylinder 3 is fixedly connected on 1 inner wall of spherical shell,
And the inflating port 1.1 on spherical shell 1 is connected to the tube inner chamber body and outside air of inner cylinder 3, the inner wall of the outer barrel 2, the outer wall of inner cylinder 3
First chamber A is constituted with 4 bottom surface of piston, and the inner wall of outer barrel 2 and 4 bottom surface of piston constitute second chamber B, on 3 barrel of the inner cylinder
It is provided with breather check valve 3.1, which is connected to the tube inner chamber body and first chamber A of inner cylinder 3, and air inlet is unidirectional
The one-way air inlet direction of valve 3.1 is to be provided with connection check valve on the piston 4 from the tube inner chamber body of inner cylinder 3 to first chamber A
4.1, and the one-way air inlet direction for being connected to check valve 4.1 is to be set on the outer wall of the outer barrel 2 from first chamber A to second chamber B
It is equipped with air inlet 2.1；
When playing basketball, sphere deforms upon so that outer barrel 2 and inner cylinder 3 slide relatively, when direction as shown in Figure 1
When inner cylinder 3 moves up, the closing of breather check valve 3.1, connection check valve 4.1 are opened, and the air in first chamber A is into goal at this time
Body；When inner cylinder 3 moves down, breather check valve 3.1 is opened, connection check valve 4.1 is closed, and air seal is in first chamber A in ball
In second chamber B, thus will not gas leakage.
Further, the inner wall junction of the outer barrel 2 and spherical shell 1 is filled with silica gel, the inner cylinder 3 and spherical shell 1
Inner wall junction is filled with silica gel；So as to improve the feel of these junctions；
In addition：It should be noted that above-mentioned specific implementation mode is only a prioritization scheme of this patent, the skill of this field
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
