Description

A high jump and long jump comprehensive training device for sports training

technical field

The invention belongs to the technical field of sports training equipment, and more particularly relates to a high jump and long jump comprehensive training device for sports training.

Background technique

Long jump and high jump are two sports in sports, which have irreplaceable sports significance for human health. High jump is mainly divided into pole vault and run-up jump. Long jump is mainly divided into rapid long jump and springboard long jump. There are different ways of using railings for high jump and sand pits for long jump. There are limited requirements for the venue and it is inconvenient to use. With the mechanized development of sports equipment, an integrated practice device has been gradually introduced.

After searching, for example, the patent No. 201721415331.7 discloses a high jumping device, which includes a cross bar, a vertical bar for supporting the cross bar, and a human-machine interface device, a driving device, a controller and a sensor. The human-machine interface device is used for Input control parameters and transmit the control parameters to the controller, the controller stores the control parameters, the driving device is used to drive the vertical movement of the vertical pole, and the sensor is used to detect the height of the vertical pole position and transmit the detected position signal to the controller, which compares the received position signal with the control parameters and controls the start and stop of the drive. The high jumping device of the present invention uses the driving device to drive the high jumping pole and can realize the automatic lifting and lowering of the high jumping pole, and realizes automatic control, which is not only convenient and fast, has small precision error, increases the fairness of the event, but also increases the fun and viewing of the event. sex.

Another example is the patent No. 201410307659.1 which discloses a sponge training long jump device; the training long jump device includes a training pit, a sponge frame with sponge, and a follower device is also set between the bottom of the training pit and the sponge frame; The take-off end falls on the sponge in the sponge frame after taking off, which plays a good buffering and protection role, and can avoid the discomfort caused by the sand entering the shoe in the traditional sand pit; when the sponge frame is under the gravity of the human body, the sponge frame is on the spring casters. Moving down, the sponge frame is pressed on the follower device. Due to inertia, the sponge frame moves in the direction of force on the follower device for a certain distance and then stops to avoid the impact force caused by the emergency stop on the human body. Slide a distance in the direction of movement to effectively protect the trainer's body.
