Abstract
The utility model relates to an improved ping pong racket. Particularly, the utility model makes improvements on pips-out rackets which are currently used. The handle point of the improved racket is provided with a ventilation hole so that sweating does not occur easily when a player grips the racket in a competition, which is favorable for the player to exert technical levels. The surface of the racket is provided with ventilation hole eyes so that air pressure difference generated between the front side and the back side of the racket when the racket is waved is reduced, air current cushions formed on the ball facing face of the racket are weakened, and eddy current formed on the back side of the racket is also weakened. Finally, air resistance is reduced, and striking speed is increased. Improvements made in the utility model are also applied to inverted rackets, long pips rackets, etc.
Description
The utility model relates to a kind of improved table tennis bat, particularly claps the improvement of being done at present employed positive glueballs.
Be accompanied by the speed and rotation two big characteristics of table tennis, table tennis technology is able to fast development.The used table tennis of competing, diameter changes 40mm (being commonly called as big ball) into by 38mm, and the generally use of the big ball of 40mm on the one hand because of enlarged diameter, and has reduced the speed and the rotation of table tennis to a certain extent, and making returns serve increases, and improves sight; Certainly will require the aerial high-speed motion of racket more from another aspect.According to aerodynamics, when racket is brandished at a high speed, to drive the surrounding air motion, front at racket, reverse side all produces active force, because of hitting surface is that the plane forms mattress, reverse side of racket then forms eddy current because of the speed of brandishing reaches to brandish repeatedly soon, this variation will be along with each player's strength, the angle of holding bat, the batting custom, the speed of ball and rotation, having nothing in common with each other of internal and external factors such as the batting frequency of returning serve, and the drop point and the stability of batting is impacted and (as often seeing the topnotch athletic ball hit in the air, rather than the ball case of that side of adversary, and players was often bowed and was seen racket this moment, seem and feel puzzled very much), therefore, the air force condition of improvement table tennis bat self is very important.
In addition, because this motion itself ball speed is fast, lay special stress on respond fast, therefore, to high-level player's various specification requirements exquisiteness very and accurately, and the table tennis player holds the hand of racket to perspire with exerting oneself because of nervous inevitably for a long time during the games, and increases when returning serve, when having little time to wipe, then might influence the performance of player's technical merit.
The purpose of this utility model provides a kind of improved table tennis bat, makes the player be difficult for perspiring during the games, gives full play to technical merit; And when improving racket and brandishing, change the influence that is brought because of air conditions to the stability of batting.
To achieve these goals: reduce because of the enlarged diameter of ball makes speed and rotation, certainly will require player's striking speed faster, striking force is bigger.Air is when motion, greater than the plane that is provided with air vent, based on this point, the utility model is by being provided with air vent below the table tennis bat handle to resistance that the plane produced, be difficult for when the player is held bat perspiring, help the normal performance of table tennis player's technical merit; By eyelet is set on table tennis bat, to reduce the air pressure difference that racket is produced when brandishing at a high speed, weakening racket meets to the formed air-flow pad of sphere, and because of brandish fast that racket causes moment vacuum at the eddy current of reverse side of racket formation, thereby improve the air force condition of table tennis bat.
What its technical scheme related to is a kind of improved table tennis bat, comprises the ball plate, adheres to the rubber of ball plate single or double, it is characterized in that formed gap is provided with air vent between handle and rubber; Establish the ventilation eyelet that is mutually symmetrical on the racket surface, the formed track of this ventilation eyelet is corresponding with the neighboring of racket.
The center of per three micelles of positive glue rubber is located in the position of described ventilation eyelet, and the formed track of this ventilation eyelet is the circular arc with the corresponding symmetry in neighboring of racket.The diameter of described air vent is 10-20mm, and the diameter of ventilation eyelet is 1-5mm.Can also to be at least one diameter be constituted by the aperture of 2-5mm described air vent, and the shape of air vent is linked to each other by the neighboring of this aperture successively and forms hexagon or pentagon or quadrangle
Effect of the present utility model is: the handle place at racket establishes air vent, makes the player be difficult for perspiring when holding bat match, is beneficial to the performance of player's technical merit; Establish circular arc ventilation eyelet on the racket surface, reduce the air pressure difference of the positive and negative that produced when racket is brandished, weaken racket and meet the formed air-flow pad of sphere, and the formed eddy current of reverse side of racket, finally reduce air drag, improve striking speed; The rackets such as being equally applicable to anti-glue, long glue that makes improvements.
Fig. 1 is the structural representation that the ventilation eyelet is located at racket head.
Fig. 2 is the structural representation that the ventilation eyelet is located at the racket left and right sides.
Fig. 3 is the structural representation that the ventilation eyelet is located at the racket rear end.
Description of drawings: 1 air vent, 2 ventilation eyelets.
The utility model is described in further detail in conjunction with the accompanying drawings: air vent and ventilation eyelet require to be symmetrical arranged.The described circular arc that track constituted by the ventilation eyelet can be positioned at the front end of racket, or the symmetrical left and right side that is divided into racket, or the racket below is the straight line place of rubber; The diameter of described air vent is 15mm, and air vent also can be made of the aperture of diameter by 2mm, and the shape of the air vent of this moment then links to each other by the neighboring of aperture successively and form hexagon or boundless shape or quadrangle, and the diameter of ventilation eyelet is 2mm.
