Description

Technical Field

[0001] The utility model relates to the technical field of table tennis rackets, in particular to a combined table tennis racket bottom plate structure. Background Art

[0002] In the prior art, table tennis, China's national ball, is a sport originated in the UK but is popular around the world. It includes attack, confrontation and defense. The conditions for playing table tennis are not harsh and the participation is strong. It can be played indoors and outdoors. If conditions permit, a high-end table can be used. A cement table with poor conditions can also be used. A table tennis racket consists of three parts: a base, a rubber and a sponge. The reasonable combination of the three determines the quality of a racket. We often mention terms such as "speed", "control" and "elasticity" and "softness and hardness of the base plate" for table tennis rackets. The base plate of the existing table tennis racket is used in During the use, the hardness and elasticity of the bottom plate surface are the same, while the bottom plate of the existing table tennis racket has the same hardness and elasticity during use. However, each person who uses the table tennis racket has a different playing style, so the way of using the racket is also different. The existing table tennis racket lacks the function of adjusting its center of gravity, and most of the existing table tennis rackets cannot adjust their own weight, and it is impossible to select the panel with appropriate hardness and elasticity according to the angle and strength of the incoming ball when hitting the ball. At the same time, the handle is not comfortable to hold, and the handle cannot be replaced according to the grip posture, which is very inconvenient to use.

[0003] Chinese utility model patent application number: 201821288852.5 discloses a novel table tennis racket, comprising a racket plate, a handle, a filling piece, a counterweight, a hand pull piece, and an end cap. The rear end of the handle is provided with a cylindrical groove, the inner wall of the cylindrical groove is evenly distributed with strip-shaped sliding grooves, the filling piece is a hollow cylindrical structure, the outer side of which is evenly distributed with first strip-shaped sliding protrusions, the counterweight is a hollow cylindrical structure, the outer side of which is evenly distributed with second strip-shaped sliding protrusions, the inner cavity of the counterweight is filled with a counterweight, and the hand pull piece includes a plate and a pull rod. However, this novel table tennis racket uses a built-in counterweight to adjust the center of gravity and weight of the racket. Before adjustment, the end cap must be removed. The adjustment process is slow and cannot achieve rapid adjustment of the center of gravity and weight. In addition, the length of the handle cannot be adjusted according to the user's usage habits, and the grip comfort is poor. Utility Model Content
