Description

A kind of isarithmic tennis racket

Technical field

The utility model relates to a kind of tennis racket.

Background technology

Playing tennis is a kind of sports that integrate amusement and body-building, and tennis racket does not generally have tally function, when being at tennis, needs the artificial batting number of times is added up, and this is some shortcoming when carrying out this motion unavoidably.

The utility model content

The technical problem that the utility model will solve provides a kind of isarithmic tennis racket, and it has tally function.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: it comprises framework, net and handle, and it also comprises shock sensor, the counting module on the handle, display screen, power switch and the battery on the net in addition; The power interface of counting module and the power interface of display screen are parallelly connected, and connect with power switch and battery; Shock sensor is connected with the input of counting module; The output of counting module is connected with the input of display screen.

The utility model further improves and is: it also is provided with reset button, and reset button is connected with the input of counting module; Counting module and battery are installed on handle inside; Display screen, reset button and power switch are installed on handle outer; Shock sensor is positioned at the middle part of net; Holding wire between shock sensor and the counting module is connected through conduit is inner.

Adopt the beneficial effect that technique scheme produced to be:

When being at tennis, without complicate statistics, can drop into whole-heartedly among the batting motion, increase the enjoyment of tennis the batting number of times.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the utility model electrical principle block diagram.

In the accompanying drawings: 1, shock sensor; 2, counting module; 3, display screen; 4, battery; 5, power switch; 6, reset button; 7, conduit.

The specific embodiment

Can be known that by the embodiment shown in Fig. 1-2 it comprises framework, net and handle, it also comprises shock sensor 1, the counting module 2 on the handle, display screen 3, power switch 5 and the battery 4 on the net in addition; The power interface of the power interface of counting module 2 and display screen 3 is parallelly connected, and connects with power switch 5 and battery 4; Shock sensor 1 is connected with the input of counting module 2; The output of counting module 2 is connected with the input of display screen 3; It also is provided with reset button 6, and reset button 6 is connected with the input of counting module 2; Counting module 2 is installed on handle inside with battery 4; Display screen 2, reset button 6 and power switch 5 are installed on handle outer; Shock sensor 1 is positioned at the middle part of net; Holding wire between shock sensor 1 and the counting module 2 is through 7 inner connections of conduit.

Method for using:

When playing tennis, power switch is pressed, just at this moment have tally function at square stance, the batting number of times directly is presented on the display screen, if need counting again midway, presses reset button, can restart counting, and when motion finished, the powered-down switch got final product.
