Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2 The utility model provides a technical solution: an inflatable measuring device for basketball processing, comprising a bottom plate 1, a fixed bracket 2 and a lifting motor 3, a vertical fixed bracket 2 is installed at the center of the bottom plate 1 surface, a lifting motor 3 is fixedly installed at the top of the fixed bracket 2, a longitudinal vertical slide groove 4 is opened at the center of the outer surface of the fixed bracket 2, an annular bracket 6 is fixedly installed at the left and right outer frames of the fixed bracket 2 through a bolt fixing plate 5, an upper pressure plate 7 is arranged on the top of the annular bracket 6, and a lower bracket 8 is arranged at the bottom of the annular bracket 6;

[0017] The upper pressing plate 7 is slidably connected to the fixed bracket 2 through the outer frame 9, the left and right ends of the outer frame 9 are located on the left and right outer surfaces of the fixed bracket 2, the center of the outer frame 9 is slidably connected to the slide groove 4 through the slider 10, and the outer surfaces of the left and right sides of the outer frame 9 are provided with rotating bolts 11;

[0018] A bowl-shaped bottom bracket 12 is provided at the end of the lower bracket 8 , and the bottom surface of the lower bracket 8 is connected to the inner bottom surface of the slide groove 4 via a spring member 13 .

[0019] Side panels 14 are inserted on the left and right sides of the upper pressing plate 7. The bottom surface of the upper pressing plate 7 is an arc-shaped concave surface. The arc-shaped concave surface of the bottom surface of the upper pressing plate 7 and the side panels 14 on the left and right sides are on the same horizontal plane. When the balloon is inflated to form a sphere, the top surface of the sphere is located at the arc-shaped concave surface. The side panels 14 on the left and right sides can be conveniently aligned with the reading scale 15 on the outer surface of the fixed bracket 2, so as to conveniently observe the upper and lower diameters of the sphere after the balloon is inflated. The arc-shaped concave surface can also facilitate the application of pressure to the top of the balloon to prevent the balloon from shaking.

[0020] The arc concave surface of the bottom surface of the upper pressing plate 7, the center of the annular bracket 6 and the bowl-shaped bottom bracket 12 are on the same longitudinal axis horizontal line, and the upper pressing plate 7, the annular bracket 6 and the lower bracket 8 are arranged horizontally from high to low.

[0021] The lifting motor 3 is connected to the upper pressing plate 7 via a telescopic shaft. A reading scale 15 is provided on the outer surface of the fixed bracket 2 , and an inflation needle tube 16 is fixed to the side of the fixed bracket 2 .

[0022] Working principle:

[0023] In this scheme, the basketball balloon to be inflated is placed in the bowl-shaped bottom bracket 12 at the end of the lower bracket 8, and then the inflation needle tube 16 at the outer side of the fixed bracket 2 is connected to an external air pump to perform an injection and inflation operation in the balloon. During the inflation and expansion process of the balloon, it gradually becomes larger in the annular bracket 6 until it is inflated into a spherical shape. The gravity of the spherical balloon gradually increases, and thus the bottom lower bracket 8 will move downward in the slide groove 4. At the same time, the lifting motor 3 works and drives the upper pressing plate 7 to press downward through the telescopic shaft. The arc concave surface of the bottom surface of the upper pressing plate 7 and the side plates 14 on the left and right sides are on the same horizontal plane, until the arc concave surface of the bottom surface of the upper pressing plate 7 presses on the top end of the inflated balloon to prevent the balloon from shaking, and at the same time, the readings on the corresponding reading scale 15 are observed through the side plates 14;

[0024] When the balloon is pressed downward by the upper pressure plate 7 , the outer frame 9 and the fixed bracket 2 on the back of the upper pressure plate 7 are loose and can slide up and down. The rotating bolts 11 on the outside of the outer frame 9 are used to adjust the installation tightness of the outer frame 9 and the fixed bracket 2 .

[0025] The entire balloon and the lower bracket 8 at the bottom will move downward. The diameter of the balloon after inflation can be measured by observing the readings on the reading scale 15 corresponding to the lower bracket 8 and the readings on the reading scale 15 corresponding to the side panel 14, thereby avoiding the effects of excessive inflation in the balloon and insufficient inflation causing the balloon body to deflate. During the entire balloon inflation process, the bottom is supported by the bowl-shaped bottom bracket 12 and is located in the annular bracket. The top surface of the balloon after inflation is consistent with the arc concave surface of the bottom surface of the upper pressing plate 7, thereby avoiding shaking when the balloon is pressed.

[0026] In the present scheme, the upper pressing plate 7 can also adjust the installation tightness of the outer frame 9 and the fixed bracket 2 by the rotating bolt 11 on the outer side of the outer frame 9, that is, when the lifting motor 3 is not used, the height of the upper pressing plate 7 on the fixed bracket 2 can be fixed to quantitatively control the diameter of the balloon after inflation, that is, the bottom of the balloon is still supported by the bowl-shaped base 12 when the balloon is inflated. When the balloon is inflated, the top surface of the balloon coincides with the arc concave surface of the bottom surface of the upper pressing plate 7 in the fixed state, and the inflation of the balloon by the inflation needle 16 is stopped in time.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
