Description

Improved speed display device for wrist ball

technical field

The utility model relates to a game appliance, in particular, it provides a rotating speed display device for a wrist power ball.

Background technique

Please refer to Figures 1 to 3, the conventional wrist power ball 10 mainly includes: a hemispherical plastic lower shell 11; a supporting ring 12, which is placed on the top inner side of the lower shell 11; a rotating part 13, A central shaft 131 is provided, and a groove portion 132 is formed along its peripheral surface. A hole 133 is provided on the concave groove portion 132, and the two ends of the central shaft 131 are pivoted on the support ring 12; and a transparent plastic upper The casing 14 is fixed on the top of the lower casing 11 , and a circular hole 141 is defined on the top thereof.

When playing, at first as shown in Figure 4, the head end 151 of a string 15 is inserted in the hole 133 of rotating member 13, then, as shown in Figure 5, press this rotating member 13 with thumb and push, Wrap the string 15 in the concave groove 132 in the direction of the arrow 16, leaving only a short section of the string 15 outside. Then, hold the wrist power ball 10 in one hand and the other hand as shown in Figure 6, and pull the ball in the direction shown in the arrow 17. When the string 15 is pulled outward suddenly, the rotating member 13 will be driven to rotate in the direction indicated by the arrow 18 in FIG. At this time, as shown in Figure 9, the user holds (holds) the wrist power ball 10 in the palm of the hand in time and uses point A as a force fulcrum, the arm remains still, and only the palm is transferred, and the wrist power ball 10 is shaken along the circular trajectory in a clockwise direction. (Rotate) to keep the rotating part 13 continuously in the rotating state, which can test the endurance of the user. If you turn it hard, the rotating speed of the rotating part 13 will be faster, and it will continuously emit "buzz ----- -" sound, the fastest can even reach 8000 revolutions per minute, until the wrist is sore or tired, just stop the rotation of the palm, the speed of the rotating part 13 will gradually slow down in a decelerated manner, and finally stop the transfer .

As shown in Figure 10, some operators have fixed a speed display device 21 at the bottom of the wrist ball 20 to sense the rotation speed of the wrist ball. However, as mentioned above, the rotation speed of the wrist ball can reach several thousand revolutions per minute, as shown in the figure As shown in 11, when the user wants to watch the rotational speed displayed on the display screen 211, because the rotational speed of the wrist ball is very fast, the rotational speed displayed on the display screen 211 cannot be clearly seen at all. In other words, the speed display device 21 cannot achieve Know the purpose of the speed.

Contents of the invention

The purpose of the utility model is to provide a wrist power ball rotation speed display device, which can surely let the user know the speed of the wrist power ball in high-speed operation.

The utility model is achieved in this way, and it includes a lower housing support ring, a rotating part and an upper housing, wherein:

The lower shell is generally in the shape of a hemisphere, forming an accommodating space inside, and the top is open;

The supporting ring is placed on the top inner side of the lower casing;

The upper case is generally semi-spherical in shape, with an accommodating space formed inside and an open bottom so that it is fixedly connected to the top of the lower case, and a circular notch is opened on the top;

The rotating member is slightly spherical, accommodated inside the upper and lower casings, and has a horizontal central axis, and the two ends of the central axis are respectively pivoted on the supporting ring;

A transmitter is arranged at the bottom of the lower casing, and the transmitter is equipped with an induction element, a transmitter element, a battery and a switch element inside; it also includes a combined receiving component, which is box-shaped, and has a signal conversion element, a battery and a switch element inside. There is a display screen on the top; the user quickly transfers the wrist ball with his wrist, and the sensor element of the transmitter senses the rotation speed of the wrist ball, and then converts the signal by the electronic component, and transmits it at a predetermined frequency through the transmitting element. The signal will be received by the receiving component, and the rotation speed of the wrist ball will be displayed on the display screen through the signal conversion component. A concave accommodating space is formed on the bottom of the lower casing for accommodating electronic components such as transmitters, and the accommodating space is closed by a cover. The receiving member may be secured to a belt so that it is positioned on the user's wrist.

Due to the adoption of the above-mentioned solution, the user can clearly know the speed of the high-speed wrist power ball controlled by the utility model, which is convenient for recording his own results, and can also compete with others to increase the fun of the game.
