Description
Technical field
The utility model belongs to table tennis table flexibility test equipment technical field, is specifically related to the table tennis table spring instrument of a kind of table tennis table elastic performance and table tennis jumping height.
Background technology
Table tennis also claims billiards meaning i.e. " tennis table ", is a kind of pandemic ball sports items.One of table tennis rises and is derived from 1900, sends the sound of " Ping Pong " when hitting because of it and gains the name, and just with " table tennis " official name as it, also use simultaneously in the areas such as Hong Kong and Macao in China.Table tennis is called as the national ball game of China Today, and China occupies very strong status in table tennis history, and since the sixties in 20th century, Chinese player is repeatedly obtained champion in the every ping-pong contest in the world, even repeatedly takes on all champions of whole race.
Table tennis not only has certain requirement to table tennis, racket, and billiard table is had certain standard too, comprising table tennis table elasticity.Table tennis table elasticity requires usually between the 230-260 millimeter, usually adopts 300 centimetres of the table tennis distance from bottom table tops of high-class product freely to fall, and the method that the same point test is averaged for 3 times records.
Present table tennis table flexibility test equipment, measuring the anti-pumping performance of table tennis table and the general of jumping height of soldier's pang ball all is the spring video recording that takes soldier's pang ball with high-speed camera, then with special-purpose software video recording is watched one by one, find out the peak of soldier's pang bound, very time-consuming and trouble.
The utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of table tennis table spring instrument that utilizes sound to come Quick Measurement table tennis table elastic performance.
In order to realize the foregoing invention purpose, technical solution adopted in the utility model is as follows:
A kind of table tennis table spring instrument, comprise main body framework and the measurement mechanism and the table tennis adsorbent equipment that are installed on the described skeleton, described measurement mechanism comprises that one measures sound transducer and the display screen that calculates system board and be connected with described measurement calculating system board.
Further, described main body framework comprises cabinet and the column that is installed on the described cabinet.
Further, described table tennis adsorbent equipment comprises the suction nozzle that is installed in described column upper end and is installed in the interior piston of described suction nozzle.
Further, described measurement calculating system board is installed in the described cabinet.
Further, offer a display screen at described cabinet window is installed, described display screen is installed in this display screen and installs in the window.
Further, offer a sound transducer installing hole at described cabinet, described sound transducer is installed in this sound transducer installing hole.
When the utility model uses, open and measure computing system, make table tennis under its Action of Gravity Field, do the movement of falling object by the table tennis adsorbent equipment, when table tennis falls the bump table tennis table for the first time, sound transducer clashes into the voice signal that table tennis table sends for the first time to the table tennis that receives delivers to the measurement computing system, the timing program of described measurement computing system starts, timing begins, when table tennis falls the bump table tennis table for the second time, described sound transducer clashes into the voice signal that table tennis table sends for the second time to the table tennis that receives delivers to described measurement computing system again, the timing program of described measurement computing system stops timing, and draw clocking value, then square being directly proportional of the distance (that is table tennis spring height) of using object fall in the freely falling body formula and time calculates the height that table tennis bounces, thereby obtain the elasticity of table tennis table, measure at last computing system result of calculation is delivered to display screen demonstration result.
The utlity model has following beneficial effect: precision is high, stable, easy to use, can directly show the result, can be used as the instrument of measuring the table tennis table anti-pumping performance and uses.
