Description

Table tennis exercise is with auxiliary device of scalable removal

Technical Field

The utility model relates to a sports equipment, in particular to table tennis exercise auxiliary device.

Background

The table tennis training assistor is a device for helping beginners to establish technical movement shaping, and the table tennis training assistors at home and abroad are all training assistors for helping beginners to spin up balls, exercise bare hands, exercise single person and pick up balls and the like at present. The table tennis is a rotary variable sport, including spin-up, spin-down, and spin-sideways. The positive and negative hand spin-down drawing of the ball in training and competition is a necessary technology for table tennis enthusiasts and athletes, and is also an important scoring means in table tennis sports. When the player is required to hit the ball during the spin-down ball, the player needs to have a certain arc line, and the height required by the spin-down ball is often blurred by the beginner, so that the exercise efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a table tennis exercise is with scalable auxiliary device who removes improves exercise efficiency.

The purpose of the utility model is realized like this: the utility model provides a table tennis exercise is with scalable removal auxiliary device, includes T shape bracing piece, calliper is installed at the horizontal part both ends of T shape bracing piece, the vertical portion of T shape bracing piece and the one end fixed connection of horizontal telescopic link, the other end of horizontal telescopic link and the one end fixed connection of vertical telescopic link, the other end fixedly connected with ring of vertical telescopic link.

The utility model discloses during the use, pass through calliper with T shape bracing piece and fix the lateral part at the table tennis table, adjusting position arranges horizontal telescopic link in directly over the net, adjusts the horizontal position of ring through adjusting horizontal telescopic link, adjusts the vertical position of ring through adjusting vertical telescopic link to realize the training that different positions table tennis passed through the ring. Compared with the prior art, the utility model has the advantages that the utility model can meet the exercise requirements by adjusting the height and the drop point for the exercisers with different technical levels; when a practicer does forward and backward spinning ball exercise, if the table tennis does not pass through the ring or the lower net, the skill action is not enough to cause the arc line capability, a coach can adjust the skill action of the practicer by taking the ring or the lower net as a standard, and when the skill action of the practicer is shaped and the fixed point arc line is mature highly, the practicer can be required to do exercise with different angles and different drop points through the front and back telescopic devices; the utility model discloses simple structure, loading and unloading are convenient, help the exercise of practitioner pitch arc height and placement, help improving technical merit to some extent.

In order to further improve the efficiency, the ring is a variable-diameter ring, the ring is formed by assembling a pair of elastic inner sleeves and a pair of elastic outer sleeves, and the elastic inner sleeves and the elastic outer sleeves are both arc-shaped structures. The training difficulty can be reduced by increasing the diameter of the ring or increased by reducing the diameter of the ring.

In order to enable the ring to be adjusted more conveniently, a plurality of circumferential grooves are processed on the inner peripheries of the two ends of the elastic outer sleeve, and a pair of convex ribs matched with the annular grooves are processed on the outer peripheries of the two ends of the elastic inner sleeve.

In order to further improve the convenience of adjusting the diameter of the circular ring, the annular groove and the convex edge are both arc-shaped surface structures.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is an installation schematic diagram of the present invention.

Fig. 3 is a schematic view of the cooperation between the elastic outer sleeve and the elastic inner sleeve of the present invention.

The support rod comprises a support rod 1T-shaped, a pair of calipers 2, a pair of transverse telescopic rods 3, a pair of longitudinal telescopic rods 4, a pair of circular rings 5, a pair of elastic inner sleeves 51, a pair of protruding ribs 511, an elastic outer sleeve 52 and a circular groove 521.

Detailed Description

As shown in fig. 1-3, the telescopic auxiliary device for table tennis exercise comprises a T-shaped support rod 1, two ends of a horizontal portion of the T-shaped support rod 1 are provided with calipers 2, a vertical portion of the T-shaped support rod 1 is fixedly connected with one end of a transverse telescopic rod 3, the other end of the transverse telescopic rod 3 is fixedly connected with one end of a longitudinal telescopic rod 4, the other end of the longitudinal telescopic rod 4 is fixedly connected with a ring 5, the ring 5 is a diameter-variable ring 5, the ring 5 is formed by assembling a pair of elastic inner sleeves 5151 and a pair of elastic outer sleeves 52, the elastic sleeve 5151 and the elastic outer sleeve 52 are both arc-shaped structures, a plurality of circumferential grooves 521 are processed on the inner peripheries of the two ends of the elastic outer sleeve 52, a pair of convex ribs 511 matched with the annular grooves are processed on the outer peripheries of the two ends of the elastic inner sleeve 5151, and the annular grooves and the convex ribs 511 are both arc-shaped surface structures.

The utility model discloses set up above the net when beginner trains, require the sportsman to draw the ball pitch arc to pass from ring 5 when practising, can reduce ring 5 size according to the improvement of practitioner's level, coach corrects technical motion according to the height of sportsman drawing the ball pitch arc, improves exercise efficiency, the formation of accelerated motion skill, the device can be to the practitioner of different skill levels, satisfy the exercise demand through height-adjusting, ring 5 diameter and placement; when the practitioner carries out the exercise of spin-down of positive and negative hand, if the table tennis does not pass ring 5 or drop the net, it can be not enough to show the technical action and make the pitch arc ability, and the practitioner can use this to adjust practitioner's technical action as the standard, stereotypes when practitioner's technical action to when the pitch arc height is ripe of fixed point, can be through front and back telescoping device, require the practitioner to carry out the exercise of the different placement of different angles.

The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and transformations for some technical features without creative labor according to the disclosed technical contents, and these replacements and transformations are all within the protection scope of the present invention.
