Description

Table tennis step exercising device

Technical Field

The invention relates to a table tennis exercise device, in particular to a table tennis exercise device for practicing a walking method.

Background

As is well known, the pingpong ball is called national ball in China, and has a wide mass foundation in China, the pingpong ball can treat the Alzheimer disease (commonly called senile dementia), and is generally accepted, and the pingpong ball is said to be used as a prescription for treating the Alzheimer disease without medicaments in certain hospitals in the UK. In conclusion, the advantages of playing table tennis are really many, and I do not need to state one by one.

Since many people like playing table tennis are suitable for all people, how to do home practice or entertainment and body-building without using a huge table tennis table is a subject for many people interested in studying the table tennis.

The table tennis practice device on the market at present mainly comprises two forms, the first form is that a table tennis, an elastic soft rod and a base are connected in turn and are formed. The second type consists of a rotatable ball head, a small spring (or other elastic material), a relatively fixed rod or shaft, and a base (or suction cup or clip). The table tennis exercise device of these two kinds of structures lets the user stand in a fixed position basically and practices, has the limitation to the level that improves the practitioner, and in table tennis learning, the coach who has professional level often says: the expression "three hands and seven feet" means that if a user wants to play a table tennis, the time spent on the hands is three minutes, while the time spent on the feet is seven minutes, and in a popular way, the user needs to practice a multi-step method to play the table tennis, and can exercise three paths (middle path, left path and right path) of the table tennis by moving the steps (the table tennis term is called the step method), and the user can play the table tennis freely in the table tennis actual combat only by practicing the multi-step method. The invention aims to solve the problem of the table tennis step method exercise.

Disclosure of Invention

The invention aims to provide a table tennis training device capable of training a gait, which is realized by two modes:

the first way, the exercise device is mainly composed of a fan-shaped tray, a telescopic slide rod, an adjustable support rod, a base, a middle shaft, a pin shaft, an elastic soft rod and a table tennis ball. The adjustable support rod is fixed on the base, the top of the adjustable support rod is provided with a middle shaft, and the top end of the middle shaft is sequentially connected with the elastic soft rod and the No. 3 table tennis (the ball in the middle position); the fan-shaped tray is arranged on the center shaft, the left side and the right side of the center shaft are respectively provided with a pin shaft, then the tail ends of the two telescopic slide bars are respectively and movably connected with the two pin shafts, and the heads of the telescopic slide bars on the left side and the right side are respectively connected with a No. 1 table tennis (the ball at the left side position) and a No. 2 table tennis (the ball at the right side position) through elastic soft bars. The fan-shaped tray is fixed on the middle shaft, the telescopic slide bars are respectively arranged on the pin shafts positioned at the left side and the right side of the middle shaft, and then the heads of the telescopic slide bars at the top end of the middle shaft and the heads of the telescopic slide bars at the left side and the right side are respectively connected with a table tennis ball (3 table tennis balls in total) through elastic soft rods, so that a practicer can practice the middle path and the left path and the right path (three paths for short), and the walking method and the forehand and backhand attack and defense technology of the learner are fully trained.

Because the telescopic slide bar can be extended, the angle and the distance of the table tennis balls at the left side and the right side from the center are increased after the telescopic slide bar is extended, and a practicer can hit the table tennis balls at the left side and the right side only by a large-amplitude moving step method; because the telescopic slide bar is movably connected with the pin shaft, the front and back positions of No. 1 and No. 2 table tennis balls can be adjusted by rotating the front and back angles of the telescopic slide bar, so that the long and short ball pulling exercise can be realized; if the right telescopic slide bar is retracted and rotates an angle inwards, the technique of picking and beating in the table can be practiced; in a similar way, the telescopic slide bar on the left side is retracted and rotates an angle inwards, and the screwing and pulling technology in the table can be practiced.

And in the second mode, the fan-shaped tray and the telescopic sliding rod in the first mode are replaced by a guide rail and a sliding block, the sliding block is matched with the track, the sliding block can freely slide along the length direction of the track, an elastic soft rod is fixed on the sliding block and connected with a table tennis ball, and the hitting balls at different positions can be practiced by moving the position of the sliding block. The guide rail can be provided with a plurality of sliding blocks, each sliding block is connected with a table tennis ball through an elastic soft rod, and the walking method of the learner can be well trained by moving the footsteps to realize multi-point batting.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
