Wherein: the rope is a hollow soft plastic tube.

Wherein: the middle of the rope is further provided with a set of outer rubber sleeves disposed outside the LED display panel to prevent the LED display panel from being worn.

Wherein: the handle is provided with a power switch and a mode selection button.

Wherein: the handle is further provided with a battery box, and the battery case is provided with a battery for supplying power to the electrical component of the skipping rope.

The invention has the beneficial effects that in the process of quickly moving the skipping rope from top to bottom by using the human eye visual stay phenomenon, the person who skips the rope can know the relevant information on the LED display panel in real time on the curved side of the LED display panel. , such as timing information, counting information, and so on. In addition, counting by the trigger signals of the positive and negative springs and the PCB control board can ensure that no matter what kind of skipping method, such as positive jump, debounce, pattern jump, etc., can be correctly counted and displayed correctly through the LED display panel. The number of laps.

detailed description

The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 , the skipping rope with LED dynamic display function of the present invention comprises two handles 1 , two rotating heads 4 connected to the two handles 1 respectively through two rotating shafts 3 , and two rotating heads 4 ropes 2. Wherein, one of the two rotating heads 4 is provided with a PCB control board 41, the rope 2 is a hollow soft plastic tube, and an LED display panel 51 is disposed in the middle portion thereof, and the LED display panel 51 is disposed on the rope 2 The inner wire 21 is connected to the PCB control board 41 in the rotary head 4. The middle portion of the rope 2 is further provided with a set of outer rubber sleeves 5 disposed outside the LED display panel 51 to prevent the LED display panel 51 from being worn.

As shown in FIG. 2 to FIG. 4, the rotating shaft 3 has a substantially "Y" shape in cross section, and a groove 31 is disposed at an end of the rotating head 4, and each side of the groove 31 is further provided with a groove 31. The card slot 32 is further provided with a П-shaped bracket 46 above the recess 31. The two legs of the П-shaped bracket 46 are respectively inserted into the slots 32 on both sides of the recess 31. A shoulder 33 is formed in the middle of the rotating shaft 3 located in the rotating head 4. A ball bearing 42 is disposed between the shoulder 33 and the bottom of the rotating head 4. The rotating head 41 is further provided with a positive spring 45 and a negative spring 43. The positive spring 45 and the negative spring 43 are respectively sleeved on the two legs of the П-type bracket 46, and the positive spring 45 is connected to the positive pole of the wire 21, and the negative spring 43 is connected to the negative pole of the wire 21. The PCB control board 41 is fixed above the П-type bracket 46 and is in contact with the positive spring 45 and the negative spring 43, and the PCB control board 41 is provided with signal contacts corresponding to the positive spring 45 and the negative spring 43. Further, the PCB control board 41 is provided with a timing circuit and a counting circuit electrically connected to the positive spring 45 and the negative spring 43. Furthermore, the end of the rotating head 4 is also provided with a threading hole 44 for fixing the rope 2. The skipping rope of the present invention further includes a power switch 11 disposed on the handle 1 and a mode selection button for selecting a timing mode or a counting mode; the handle 1 is further provided with a battery box, and the battery box is installed with the entire skipping rope A battery that is powered by electrical components.

When the skipping rope with the LED dynamic display function of the present invention is used, the handle 1 is swung, the rotating shaft 3 drives the rotating head 4 to rotate, and the PCB board 41 also rotates with the rotating head 4. When the PCB board 41 rotates one turn, the negative spring 43 The corresponding signal contacts on the PCB board 41 are touched, and the generated signals are transmitted to the counting circuit of the PCB board 41. After the digital board is digitally operated, the corresponding signals are converted into digital signals and output through the LED display panel 51. Since the human eye is viewing the object, the image of the object will have a visual pause of 1/24 second on the retina. This visual pause can make the human vision overlap and make the object appear to be "stationary and moving". Thus, during the rapid rotation of the skipping rope, jump The LED display panel 51 on the rope moves rapidly from top to bottom, and the person who jumps the rope can see the complete number or image on the LED display panel 51 on the curved side of the LED display panel 51.
