Abstract

The utility model relates to a ball capable of recording beating frequency, which comprises a ball body, a cube groove and a register. When people start playing the ball, a sway spring of a vibration switch continuously sways on every beating, the sway spring only generates one sway amplitude peak value on every beating because of the continuous reduction of amplitude, the sway amplitude peak value of every beating can trigger the vibration switch for closing, and closing of the vibration switch leads a circuit to be electrified and the register to start working. Additionally, since the vibration switch is a normally-open point-triggered closing switch, the closed vibration switch is automatically disconnected when the sway spring does not trigger the switch, when the ball is beat for the second time, the register continues performing according to the previous time, and accordingly the ball achieves the purpose of counting.

Description

Ball

Technical field

The utility model relates to a kind of sports equipment-----ball, refers specifically to a kind of ball that can write down the beating number of times automatically.

Background technology

Ball kind in the market is a lot, football, vollyball, basketball etc. are arranged, these balls are that people join into sports, the instrument of body-building, but for professional ball game project, training requirement to the sportsman is very strict, each project all will test and examine, and the standard of test and examination all is to weigh the number of times of ball continuously in the hand based on the unit interval, like this when test and examination, the mode that the test and appraisal teacher will stand by with the number number writes down the number of times that measured people weighs ball in the hand, makes record very difficult, and great majority write down and all mistake can occur.

In order to solve the problem that exists in the above technology, the utility model proposes following technical solution together.

Summary of the invention

1, this practicality is made up of spheroid, square groove and register three parts, register is made up of vibroswitch, IC, LCD display, battery etc., spheroid is seen at ordinary times the same with the ball that uses with us, after the sufficient gas, have very high elasticity, can pat for people, one groove is arranged on spheroid, one register is arranged in the groove, a vibroswitch is installed on register, the unlatching of vibroswitch is to realize by the spring that waves of its inside with closure.

In the process of making spheroid, the utility model is square groove of design below the surface of spheroid, being used for installing counter uses, the register that has vibroswitch is installed wherein, make the register LCD display outwards equal with outer surface of spheroid, inwardly and groove to pass through all-purpose adhesive bonding, in the process of playing ball along with the vibration of spheroid, register in memory, shows the number of times accurate recording patted simultaneously on LCD display.The storage maximum accumulative total of register reaches 9999 with regard to auto zero, and record high all can be kept in the memory chip automatically, accesses at any time in order to people and checks.Design has the zero clearing button on register in addition, and battery is installed in register, is used for supplying with register work, can change after battery uses up, and when ball does not use, enters resting state (energy-saving mode) after 10 seconds automatically.The utility model is given people's sports, and body is examined test and appraisal and brought great convenience, and is widely used in international sports event, the anxious instruction of physical culture, aspects such as student movement.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

As figure is structure chart of the present utility model.

The specific embodiment

The utility model is by spheroid 1, square groove 2 and register 3 three parts are formed, wherein register is by vibroswitch, IC, LCD display, compositions such as battery, when people begin to play ball, every beating once, the bullet cage that waves of vibroswitch just constantly waves, because constantly weakening of amplitude, wave spring when making each beating and only produce amplitude of oscillation peak value one time, each amplitude of oscillation peak value of patting can both trigger vibroswitch and advance closure once, at this moment because the closure of vibroswitch, switch in the circuit, register is started working, again because vibroswitch is the normal moving Closing Switch of making war, closed vibroswitch wave spring when not triggering it with regard to automatic disconnection, when patting ball for the second time, register once carries out according to this continuously according to preceding, thereby reaches the purpose of numeration.

Claims (3)

1. one kind can be write down the ball of patting number of times automatically, it is characterized in that a groove is arranged on spheroid, and a register is arranged in the groove, and a vibroswitch is installed on register, and the unlatching of vibroswitch is to realize by the spring that waves of its inside with closure.

2. can write down the ball of patting number of times automatically by claim 1 is described, it is characterized in that vibroswitch wave spring be on the register normal battle moving Closing Switch the contact.

3. by the described a kind of ball that can write down the beating number of times automatically of claim 1, it is characterized in that ball of every beating, because vibration, the waving spring and will carry out vacillating now to the left, now to the right many times of vibroswitch, because constantly weakening of vibration intensity, the rocking tendency that waves spring also constantly weakens thereupon, so each beating just has one to wave the peak value generation.
