Description
Technical Field
The utility model relates to the technical field of sports goods, in particular to a plate-type racket capable of setting the gravity center position.
Background
Table tennis, beach ball, and slate tennis are all popular board-like ball games. The prior plate-type rackets such as table tennis, beach ball and plate tennis have a plurality of defects: 1. the existing plate-type racket, no matter made of wood or other materials, does not set the position of the racket gravity center in advance according to the sport habit, thereby influencing the exertion of the sport result. 2. The center of gravity of the racket cannot be guaranteed to be positioned on the central axis of the racket, so that the center of gravity of the racket is unbalanced; 3. the racket using wood as raw material has the advantages that the wood resource is limited due to the long growth period of trees, so that the raw material cost of the racket is greatly increased; 4. the production process of the wooden racket is complicated, mainly manual work, low in production efficiency and high in production cost, and the surface paint spraying process can cause environmental pollution; 6. the bat with a wood structure is easy to deform after encountering water, and particularly for table tennis balls with multiple layers of wood chips glued together, the bat surface can be layered to a certain extent when meeting water or being used for too long time; 7. the plate-type racket also has certain requirements on gram weight, but the weight of the prior racket is generally heavier due to the problems of material and structure, and exceeds the gram weight standard required by sports; 8. in the ball sports using the plate-type bat, particularly in the process of table tennis, the edge of the plate-type bat is the part which is contacted with a table top, the ground and the like at most, for example, the edges at two sides of a handle of the table tennis bat are shiny, particularly, the edge far away from the handle is contacted most easily, therefore, along with the lengthening of the service time, the edges are damaged more or less, the existing table tennis bat leaves a factory, a manufacturer can provide an edge with sticky strap attaching strip to the wooden edge of the brand-new table tennis bat and attach the sticky strap attaching strip to the wooden edge to protect the periphery of the wooden plate, however, the strap attaching strip is easy to damage, and after the bat is used, the edge of the wooden plate is damaged and is not flat any more, and the surface is attached with dust, so that the strap attaching strip cannot be attached repeatedly. The cloth tape adhesive strip can not adhere to the sponge layer and the rubber layer on the front side and the back side of the table tennis bat, so that the sponge layer and the rubber layer are not protected by any protective objects all the time and are most easily damaged.
