Abstract
A novel table tennis racket pimples-in rubber relates to a table tennis sporting apparatus. Compared with traditional cylindrical micelle pimples-in rubber, the novel pimples-in rubber improves gyres speed and rotational speed while beating table tennis under the same condition and comprises bottom leathers and micelles. In addition, the pimples-in rubber is characterized in that towered micelles are provided as the micelle. Bottom of the towered micelles is fixed on the bottom leather. Bottom cross section of the towered micelles is larger than top cross section of the towered micelles. Due to larger cross section of the towered micelles, the rubber can generate lower intensity of pressure, bending and deformation under the same applied force. Therefore, energy lost due to bending and deformation is lower. Gyres speed and rotational speed of the table tennis racket are superior to those of table tennis racket provided with traditional cylindrical micelle pimples-in rubber, thus enhancing table tennis gyres speed and rotational speed. Moreover, the rubber conforms to regulations of International Table Tennis Federation on replacing competition table tennis with large one with diameter of 40 mm and benefits to increase gyres speed and rotational strength.
Description
Technical field:
The utility model relates to a kind of table tennis apparatus.A kind of novel trans glue of table tennis bat particularly.
Background technology:
Table tennis has in recent years become an important component part in sports circles, and the level of soldier's pang ball motion is improving constantly.Along with the raising of soldier's pang ball Motion Technology, must require innovation constantly to soldier's pang ball equipment, and the innovation of soldier's pang ball equipment will promote the development of soldier's pang ball motion biglyyer.
Modern soldier's pang playing skill art is based on speed that improves table tennis and the rotation dynamics that increases table tennis.Especially after October calendar year 2001, International Table Tennis Federation's regulation official ball is used the big ball of 40mm instead, and the speed of table tennis and the raising of rotation dynamics are had higher requirement.How to improve the return of serve speed of table tennis bat and the new problem that spin intensity becomes the table tennis apparatus.
In table tennis, the performance of the anti-glue of table tennis bat is inseparable with the speed of soldier's pang ball and the raising of rotation dynamics, and it is one of key factor that improves table tennis speed and rotation dynamics.And in the performance of the anti-glue of table tennis bat, except that improving the material capability of making the glue face, the shape of micelle is one of important decisive factor that improves the anti-colloidality energy of table tennis bat.The anti-glue of table tennis bat that uses comprises end skin and columniform micelle at present, and columniform micelle bottom is identical with the diameter at top, under the identical batting situation, the compression and the flexural deformation of micelle are bigger, and energy loss is big, and the return of serve speed and the spin intensity of table tennis relatively reduce.Especially after International Table Tennis Federation's regulation official ball was used the big ball of 40mm instead, the contact-making surface of anti-glue of square stance table tennis bat and ball increased, because the energy loss that compression and flexural deformation produce can be bigger, the incompatibility table tennis improves constantly.
Summary of the invention:
The utility model aims to provide a kind of novel trans glue of table tennis bat, compares with the anti-glue of traditional cylindrical micelle, and under same case, square stance crooked and distortion and the energy loss that produces is less by micelle can improve the speed and the spin intensity of return of serve.
The utility model comprises end skin and micelle, and wherein micelle is the turriform micelle, and turriform micelle bottom links to each other with the inner face of end skin, and the cross-sectional area of turriform micelle bottom is greater than the cross-sectional area at turriform micelle top.
Turriform micelle cross section can be geometric figures such as circle, ellipse.As Fig. 1, shown in Figure 2.
The utility model is attached on the spongy layer of table tennis bat with turriform micelle top as the anti-glue of table tennis bat; Be that turriform micelle top and spongy layer are bonding, turriform micelle bottom links to each other with the inner face of end skin, and the outside of end skin is the face of table tennis bat.As shown in Figure 3.
When sportsman's square stance of swinging the bat, come the pellet impact table tennis bat after, change direction, becoming return of serve and hitting.Under the situation of not considering athletic active force, according to law of conservation of energy, the speed of return of serve and spin intensity and the table tennis bat energy loss in the process of batting has direct relation, and this energy loss is more little, and the speed of return of serve and spin intensity are big more.
Because the turriform micelle that the utlity model has, turriform micelle bottom transverse sectional area is greater than the top cross-sectional area, therefore, under the turriform micelle top cross-sectional area situation identical with the top cross-sectional area of cylindrical micelle, turriform micelle bottom transverse sectional area is greater than the bottom transverse sectional area of cylindrical micelle.
When the sportsman swings the bat with identical power square stance, compare with the anti-glue of traditional cylindrical micelle, act on the pressure that the pressure of turriform micelle bottom will be subjected to less than cylindrical micelle bottom, like this, compression that turriform micelle bottom produces and flexural deformation is less, thereby crooked and distortion and the energy loss that produces are with less by micelle.Therefore, under the same conditions, use the table tennis bat square stance of the anti-glue of turriform micelle, the return of serve speed of table tennis and spin intensity will be greater than the return of serve speed and the spin intensities of the table tennis bat that uses traditional anti-glue of cylindrical micelle.Therefore, use the utility model can improve the return of serve speed and the spin intensity of table tennis.And be suitable for International Table Tennis Federation equally and change the regulation that diameter is the big table tennis of 40mm into, the raising of speed that helps returning serve and rotation dynamics about official ball.
Description of drawings:
Fig. 1 is a partial elevational schematic diagram of the present utility model.
Fig. 2 is partial side, cross-sectional view of the present utility model (amplification).
Fig. 3 is for having table tennis bat cross section structure schematic diagram of the present utility model.
Wherein,
Skin at the bottom of the 1-, intracutaneous face at the bottom of the 2-, skin outside at the bottom of the 3-, 4-turriform micelle, 5-turriform micelle top, 6-turriform micelle bottom, 7-sponge, 8-wooden bat.
The specific embodiment:
Employing hardness is the novel trans glue that 48 ° rubber is made the table tennis bat that comprises turriform micelle 2 and end skin 1.The thick of its end skin 1 is 0.8mm, and the cross section of its turriform micelle 4 adopts circular, and the diameter that makes its turriform micelle top 5 is 1.6mm, and the diameter of turriform micelle bottom 6 is 2.3mm, and the height of turriform micelle 4 is 0.8mm.The utility model oppositely is attached on the spongy layer of table tennis bat, becomes and have table tennis bat of the present utility model.As shown in Figure 3.
Use this table tennis bat square stance in play, under equal conditions, because the bending of turriform micelle and distortion are less, thereby energy loss is less, and the return of serve speed of square stance table tennis and spin intensity are just bigger, and it is fast to have return of serve speed, the characteristics that revolving force is strong.
Have table tennis bat of the present utility model trying out of the national table tnnis team of process, respond well, the return of serve speed that can reach expection is fast, the effect that revolving force is strong.
