Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to explain the technical solution of the present invention, the following description is made by using specific examples.

As shown in fig. 1-4, the table tennis exerciser provided in this embodiment includes a base 1, a V-shaped groove 2 is formed in the center of the top of the base 1, a sheet-shaped rod 3 is connected to a rotating shaft at the lowest position of the V-shaped groove 2, an elastic steel wire 4 is installed on the top of the sheet-shaped rod 3, and a rotatable ball head 5 is installed on the elastic steel wire 4. In this structure, base 1's bottom disposes and heavily boards 7, and the effect of heavily boards is the stability that increases the device, and heavily board and base pass through screw locking, both demountable installation, the production of being convenient for.

The table tennis trainer is mainly characterized in that a sheet-shaped rod body is adopted and made into a table top type or a ground type. A V-shaped groove is formed in the center of the base, a rotating shaft at the bottom of the sheet-shaped rod body is connected to the lowest position of the V-shaped groove, and the front slope surface and the rear slope surface of the V-shaped groove are used as limiting positions for the sheet-shaped rod body to swing back and forth. The sheet-shaped rod body is in a long sheet shape, the positions of the front left side edge and the front right side edge are thickened, and the strength and the toughness of the sheet-shaped rod body are ensured. When the trainer is used, the trainer is placed on a table top or the ground, a learner strikes the ball head, the sheet-shaped rod body and the whole ball head can only swing back and forth within a certain range, the ball head basically cannot swing laterally due to the structural characteristics of the sheet-shaped rod body, the trainer is particularly suitable for beginners to practice, and after the ball head is struck, the ball body rotates, and meanwhile, the obvious motion track characteristic of back and forth swing is realized, so that the hitting reality is improved; meanwhile, after the ball head is hit, the rebound is slow, and the ball is particularly suitable for beginners.

In the embodiment, the sheet-shaped rod body is made of food-grade plastic PP hectorite, compared with the rod body made of metal materials of the existing finished product in the market, the sheet-shaped rod body of the product has lighter weight, the hitting hand feeling is further close to a free sphere, and the hitting woody hand feeling of the ball practicing device popular in the market is greatly improved. The mass ratio of the ball head to the club body can be obviously improved, and the batting hand feeling is favorably improved.

As a preferable structure, the blocking pieces 6 capable of moving back and forth are arranged on the top of the base 1 and on the two sides of the V-shaped groove, specifically, screw holes are formed in the top of the base 1 and on the two sides of the V-shaped groove, an elongated groove 11 is formed in each blocking piece 6, and each blocking piece 6 penetrates through the elongated groove 11 through a screw and is screwed into each screw hole for locking. When the inner sides of the blocking pieces are adjusted into the V-shaped grooves, the sheet-shaped rod bodies are in contact with the inner sides of the blocking pieces, the starting positions of the ball heads can be adjusted by the blocking pieces, and meanwhile, the sheet-shaped rod bodies are limited to swing back and forth within the range of the inner sides of the two blocking pieces, so that the swing amplitude and the rebound speed of the ball heads can be conveniently adjusted and improved to be suitable for learners of different levels. The trainer can be used as an assistant for a trainer in a training class of children to improve the learning efficiency, and can also be used as a self-learning tool of amateurs or an entertainment tool of body building amateurs.

In order to facilitate production, all parts of the product are designed into a detachable installation mode as much as possible. In this embodiment, the pivot can be dismantled in slice shape pole body bottom install in V type groove lowest position, for example, slice shape pole body bottom is the cylinder, and V type groove lowest position is opened has the arc groove, and the bottom cylinder of slice shape pole body penetrates the arc groove from the side, then the side in V type groove blocks through other baffles can. In addition, as shown in fig. 5-7, the elastic steel wire 4 is one, and the left and right sides of the elastic steel wire after passing through the ball head are bent downwards to form a door-shaped structure, which is bent by 90 degrees as shown in the figure. The lock comprises a sheet-shaped rod body 2, a lock sleeve 8 penetrates through the sheet-shaped rod body 2, L-shaped hook grooves 21 are symmetrically formed in two sides of the top of the sheet-shaped rod body 2 inwards, the bottom ends of the left part and the right part of the elastic steel wire 4 are bent inwards and inserted into the L-shaped hook grooves 21 on the corresponding sides, a plurality of convex strips 81 are arranged on the inner wall of the lock sleeve 8, grooves 22 corresponding to the convex strips are formed in the front face and the back face of the top of the sheet-shaped rod body 2, the convex strips 81 of the lock sleeve are embedded into the corresponding grooves 22, and the middle lower parts of the left part and the. After the product is assembled, the two ends of the elastic steel wire are limited in the L-shaped hook groove, when the product needs to be disassembled, the sliding sleeve is pushed downwards by force, the raised lines of the sliding ways are separated from the grooves in the surface of the sheet-shaped rod body, the elastic steel wire is completely exposed at the moment, and therefore the elastic steel wire can be taken out from the L-shaped hook groove, and the elastic steel wire and the ball head integral structure are taken down. Parts of each part of the device can be independently manufactured and then assembled, the assembling process is simple, and the labor cost is reduced. Meanwhile, materials of all parts of the product are common and low in price, so that the overall cost of the product is low, the product has wide application scenes, is convenient for market popularization, and is more favorable for popularization and development of table tennis.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
