Description

A kind of dragon backbone type table tennis bat

Technical field

The utility model relates to a kind of imperial backbone type table tennis bats.

Background technique

Table tennis is the movement using tool, and the height of table tennis level depends on table tennis bat to a certain degree Scientific and reasonable design.Sportsman when using conventional racquets often due to the reasons such as difference of holding bat or forehand it is quite a lot of or Backhand is quite a lot of, and having an effect for index finger is not enough, to find out its cause, the design of mainly conventional racquets is perhaps too simple, not enough Carefully,

Summary of the invention

The utility model provides a kind of imperial backbone type table tennis bat, solves above-mentioned technical problem in the prior art, This design clapped have passed through years of researches, have passed through practice and demonstration again and again, more rationally, more compared to conventional racquets Science has greatly reinforced the reasonability held bat, stability, not only mentions significantly compared to conventional racquets either forehand or backhand The high momentum to ball, especially forehand.And forehand-stroke shape conversion backhand-stroke shape is accelerated, backhand-stroke shape converts forehand-stroke shape Speed, make clap shape control it is more natural, more reasonable, more stable.Specific technical solution is as follows:

A kind of dragon backbone type table tennis bat, is made of racket handle and racket face, which is characterized in that in the imperial backbone type table tennis Imperial vertebral structures are provided on the backhand face of pang racket, the dragon vertebral structures originate in racket front end of line and clap axis The infall of line, and along with clap the arc-shaped extension of angle about 25 ° of central axes, the dragon vertebral structures include two imperial ridges, Streamlined slot, three dragons are slitted, and the dragon slot position between described two imperial ridges, slit perpendicular to the imperial spine by three dragons Interval is arranged and divides two imperial ridges and streamlined slot on structure direction.

Preferably, described two imperial ridge shapes are the thin rod of semicircle, and the thin rod cross section diameter of semicircle is 2.8 millimeters.

Preferably, the depth and width of the imperial slot are 1.4 millimeters, and the open-minded depth of the dragon is 4 millimeters.

Preferably, the central axes of described two imperial ridges are in parallel relation on vertical plane.

Specific embodiment

Length unit in Figure of description Fig. 1 and Fig. 7 is millimeter.

It (is not repeated under by taking the right hand is held bat as an example) on backhand face referring to Fig. 1-Fig. 7, to clap front end of line and clap in It is originated at Axis Cross, designs an imperial vertebral structures along with the angle direction for clapping about 25 ° of central axes.The master of imperial vertebral structures Want purposes to be engaged for index finger with it, index finger to it have an effect and when froehand-backhand bat shape is converted index finger using it into the rotation of axis.

In the imperial vertebral structures plan-position figure of Fig. 1, H-H ' is clapped central axes, and W-W ' is to clap front end of line, to clap in Axis and bat are the rectangular co-ordinate of front end of line, it is determined that imperial vertebral structures are in the plane of 5 points a, b, c, d, e of lonely shape edge line Position.

Referring to fig. 2-(1) and Fig. 2-(2), imperial vertebral structures top is by two imperial ridges, an A dragon ridge, a B dragon ridge, and One imperial slot composition, and downwards, be to the right in the extension of once radians.

In the imperial chi chung axis and hatching plane distribution dimensional drawing of Fig. 3, to clap central axes H-H ' and clap front end of line W-W ' is rectangular co-ordinate, it is determined that 5 points of edge line (and starting point of imperial vertebral structures horizontal section line) of imperial vertebral structures C, the coordinate position of D, E, F, G.And A dragon chi chung axis (A-A1 to A6-A7) and B dragon chi chung axis (B-B1 to B6-B7) and dragon Vertebral structures edge line (C, D, E, F, G line) is in parallel relation on vertical plane.Its parallel spacing: A dragon chi chung axis It is 1.4 millimeters (mm) with imperial vertebral structures edge line, B dragon chi chung axis and imperial vertebral structures edge line are 5.6 millimeters (mm) (referring to Fig. 7).

The imperial vertebral structures B dragon ridge B-B8 axis longitudinal sectional drawing of Fig. 4 shows that imperial ridge and imperial slot are slitted by three dragons and divide It opens, B dragon ridge is slitted by three dragons and divides in a lonely shape, wherein imperial open-minded depth is 4 millimeters, need to illustrate A dragon ridge and B dragon ridge axis Line profile is identical, therefore is not repeated.

In the imperial vertebral structures B dragon ridge of Fig. 5 and each inflection point axis longitudinal profile dimensional drawing, each inflection point B, B1 ... arrives B8 Vertical line of the position dimension by plate face line and bat front end of line is put to determine.

In each horizontal section of imperial vertebral structures (1)-(5) figure in Fig. 6, the depth and width of imperial slot are 1.4 millimeters.

Referring to Fig. 7 (1)-(5), imperial ridge (A dragon ridge and B dragon ridge) shape is the thin rod of semicircle, and the thin rod cross section diameter of semicircle is 2.8 Millimeter, position is imperial slot between two imperial ridges, and the depth of imperial slot is 1.4 millimeters.

The important function of imperial spine is exactly the potential for giving full play to index finger when playing table tennis:

1, it when hitting forehand, with rightmost side position below index finger (Fig. 8 shade position), is press-fitted using A-A7 as axis A dragon ridge on (except finger tip), this point is extremely important.Due to the design that imperial vertebral structures top dragon ridge, imperial slot, dragon are open-minded, make The rightmost side and being engaged for dragon vertebral structures are very good below index finger, will not skid, and left half part (Fig. 8 below index finger at this time Position other than shade) be it is hanging, then entire index finger is downward, and Xiang Shouxin has an effect in direction, because the index finger of slightly lonely shape is to hand Heart direction is had an effect, that is, formula of clenching fist is had an effect, it has an effect very sufficiently, persistently, in addition, due to the contact of index finger and A dragon ridge It is the rightmost side position of index finger, index finger just has the torque of lateral (with imperial ridge vertical direction) to the active force of imperial vertebral structures, When index finger is had an effect, not only there is pressure to the active force of imperial vertebral structures, there are also (in other words in face of carry out direction of bowl) to the left to imperial ridge Bone structure application is broken, the active force pulled.The effect got twice the result with half the effort, several factor superpositions are played, index finger acts on imperial spine Active force very sufficiently, persistently, is transmitted on impact table tennis, compares conventional racquets, greatly improve and flick (including hit Ball and friction ball) when momentum.

2, to the effect of positive and negative handball conversion, when forehand is converted into backhand, the relatively imperial vertebral structures of index finger will have One rotation counterclockwise, imperial vertebral structures become the axis of index finger rotation again at this time, left more than half below index finger when due to forehand The shape of the hanging and imperial ridge section semicircle of side, index finger can be rotated counterclockwise by axis moment of imperial vertebral structures, be greatly speeded up Forehand-stroke shape changes into the speed of backhand-stroke shape, while imperial spine becomes depending on and propping up for index finger again after convert backhand-stroke shape Support, more conducively thumb are had an effect, and compared to the stability of conventional racquets backhand-stroke shape, also there is great raising, to the momentum of ball Also there is big promotion, and it is that same reason is not repeated that backhand-stroke shape, which turns forehand-stroke shape,.
