The inflating pump disclosed by the utility model can inflate footballs, volleyballs and basketballs, also can utilize attached gas-pressure meter and dividing ruler to detect the air pressure and perimeter of the used ball at any time, and provides scientific guarantee so that rule requirements can be strictly complied in teaching, training and matching of the footballs, the volleyballs and the basketballs.
Description
Technical field
The utility model relates to a kind of ball inflator special, belongs to the sports equipment technical field.
Background technique
The football competition rule of International Federation of Association Football promulgation has girth, the air pressure of football and explicitly calls for: promptly: the circumference of football no longer than 70 centimetres (28 inches), be not shorter than 68 centimetres (27 inches); Pressure equals 0.6-1.1 barometric pressure (600-1100 gram/square centimeter, 8.5-15.6 pound/square inch) on the sea level.
The volleyball competition rule (2009--2012) of International Volleyball Association promulgation also has girth, the air pressure of vollyball and explicitly calls for: promptly: the circumference of vollyball should be at 65 centimetres in 67 cm range.Air pressure inside should be in 294.3 to 318.82 millibars of (0.30 to 0.325 kilogram every square centimeter) scopes.
The basketball competition rule of International Basketball Association's promulgation explicitly calls for the girth of basketball: promptly: the basketball girth should be greater than 74.9 centimetres, less than 78 centimetres.
But; And during the games at present in football, vollyball, basketball movement teaching, training; Owing to lack a kind of easy, practical measurer, girth, air pressure detect and often are left in the basket, and this just makes teaching, training and match be among a kind of risk of departure from these rules requirement.
Summary of the invention
The purpose of the utility model is to provide a kind of ball inflator special, satisfies ball air pressure and detects the demand that detects with girth.
The technological scheme that the utility model is taked is:
Ball inflator special comprises pump, gas tube, air tube, and the outside tube wall of gas tube is provided with curve bath, is provided with calibrated scale along the curve bath of gas tube, gas tube be provided with barometer with the air tube connecting part.
Described calibrated scale comprises 0 scale area, vollyball girth interval of acceptance, football girth interval of acceptance and basketball girth interval of acceptance.
Vollyball air pressure interval of acceptance and football air pressure interval of acceptance are arranged on the described barometer.
The utility model both can have been given football, vollyball, basketball inflation; Can utilize subsidiary barometer, calibrated scale at any time air pressure, the girth of balls to be detected again, can strictness fulfiling rule request for the teaching of football, vollyball, basketball movement, training, match provides the science guarantee.
Description of drawings
Fig. 1 is the overall schematic of the utility model;

Among the figure: 1, pump; 2, gas tube; 3, barometer; 4, air tube; 5,0 scale area; 6, vollyball girth interval of acceptance; 7, football girth interval of acceptance; 8, basketball girth interval of acceptance; 9 vollyball air pressure interval of acceptance; 10 football air pressure interval of acceptance; 11, gas tube tube wall; 12, gas tube tube chamber; 13, curve bath.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Like accompanying drawing 1,2, shown in 3, ball inflator special comprises pump 1, gas tube 2, air tube 4, and the outside tube wall of gas tube 2 is provided with curve bath 13, is provided with calibrated scale along the curve bath 13 of gas tube, gas tube 2 be provided with barometer 3 with the air tube connecting part.
Described calibrated scale comprises 0 scale area 5, vollyball girth interval of acceptance 6, football girth interval of acceptance 7 and basketball girth interval of acceptance 8.
Be designed with vollyball air pressure interval of acceptance 9 and football air pressure interval of acceptance 10 on the described barometer 3.
Method for using:
Vollyball air pressure detects
(1) at first, to the vollyball inflation, the scale of observing at any time in the barometer 3 changes with pump 1, when scale gets into vollyball air pressure interval of acceptance 9 (0.30-0.325 kg/cm), promptly accomplishes the gas replenishment process to vollyball.
(2) if air pressure exceeds 0.325 kg/cm, can air tube 4 be taken off from gas tube 2, insert separately in the vollyball air-filled pore, discharge gas in a part of ball.
(3) air tube 4 is installed on the gas tube 2, inserts again in this ball, observe scale value in the barometer 3 whether in vollyball air pressure interval of acceptance 9.If still exceed 0.325 kg/cm, repeated for (2) step; If be lower than 0.30 kg/cm, repeated for (1) step.Repeatable operation, the scale value in barometer 3 are presented in the vollyball air pressure interval of acceptance 9.The air pressure of this vollyball is and meets rule request at this moment.
Football air pressure detects
(1) at first, to the football inflation, the scale of observing at any time in the barometer 3 changes with pump 1, when scale gets into football air pressure interval of acceptance 10 (0.6-1.1 kg/cm), promptly accomplishes the gas replenishment process to this ball.
(2) if air pressure exceeds 1.1 kg/cm, can air tube 4 be taken off from gas tube 2, insert separately in the football air-filled pore, discharge gas in a part of ball.
(3) air tube 4 is installed on the gas tube 2, inserts again in this ball, observe scale value in the barometer 3 whether in football air pressure interval of acceptance 10.If still exceed 1.1 kg/cm, repeated for (2) step; If be lower than 0.6 kg/cm, repeated for (1) step.Repeatable operation, the scale value in barometer 3 are presented in the football air pressure interval of acceptance 10.The air pressure of this football is and meets rule request at this moment.
The vollyball girth detects
When carrying out the detection of vollyball girth,
(1) with ball fixed placement to be detected;
(2) two ends of hand-held gas tube 2 are with gas tube tube wall outer arcuate groove 13 subtend spheroids;
(3) tightly enclose along the spheroid maximum perimeter around one;
(4) the other end that makes calibrated scale 0 calibration points and gas tube tube wall outer arcuate groove 13 behind the spheroid near;
(5) calibrated scale from gas tube tube wall outer arcuate groove 13 reads this ball girth numerical value;
(6) utilize vollyball girth interval of acceptance 6 (65-67 centimetre) to judge vollyball to be detected and whether meet rule request.Shown in Fig. 3 (gas tube cross sectional representation):
The utility model is designed with the curve bath 13 in the gas tube tube wall outside on gas tube tube wall 11, when measuring the spheroid girth, gas tube tube wall outer arcuate groove 13 can be fitted with spherome surface preferably, in case gas tube 2 (calibrated scale) slippage.On the curve bath 13 in gas tube tube wall 11 outsides, be designed with calibrated scale, 80 centimetres of total lengths (being accurate to 0.1 centimetre).Be marked with vollyball girth interval of acceptance 6, football girth interval of acceptance 7 and basketball girth interval of acceptance 8 at calibrated scale.
The football girth detects
(1) to (5) step is detected step with the vollyball girth;
(6) utilize football girth interval of acceptance 7 (68-70 centimetre) to judge football to be detected and whether meet rule request.
The basketball girth detects
(1) to (5) step is detected step with the vollyball girth;
(6) utilize basketball girth interval of acceptance 8 (74.9-78 centimetre) to judge basketball to be detected and whether meet rule request.
