Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The present embodiment provides an injection-molded integrally-formed paddle racket, as shown in fig. 1 to 7, including a racket face portion 1 and a racket handle portion 2. A plurality of independent filling cavities 7 are arranged in the racket face part 1, one end of each filling cavity 7 is closed, the other end of each filling cavity 7 is open, and a seal is arranged at the open end to seal the filling cavities. The handle part 2 is provided with an independent hollow structure 8, one end of the hollow structure 8 is closed, the other end of the hollow structure 8 is open, the open end of the hollow structure 8 is far away from the racket face part 1, and the port of the open end of the hollow structure 8 is provided with a cover 3 for closing the end. The foaming material can be injected into the filling cavity 7 of the racket face part 1 by opening the seal, and the seal is closed after the foaming material is injected. The foaming material can increase the thickness of the racket face part 1 and partially absorb the vibration generated when the racket strikes the ball, so that the striking elasticity of the racket face is improved, the kinetic energy of the racket face striking the ball is prevented from being consumed by the vibration, and the flying distance and the flying precision of the ball are reduced. The racket face part 1 and the racket handle part 2 in the injection molding plate type racket are formed by injection molding once, so that the problem that the wooden racket is easy to deform when meeting water and the problem that the surfaces of the wooden racket are layered can be avoided. Face portion 1 and handle portion 2 are hollow structure in this application, can show to reduce the whole weight of the board-like racket of moulding plastics, have solved the heavier problem of traditional racket.

In the present embodiment, as shown in fig. 1 to 7, the hollow structure of the handle portion 2 is filled with foam.

In this embodiment, as shown in fig. 1 to 7, the filling cavities 7 are independent from each other and do not communicate with each other.

In the present embodiment, as shown in fig. 1 to 7, mutually independent filling cavities 7 are formed in the paddle portion 1 by the support strip 6.

In this embodiment, as shown in fig. 1 to 7, the open ends of the hollow structure 8 of the cover 3 and the handle 2 can be formed by adhesive, plug-in, interference structure or snap-fit. When the cover 3 is in an insertion mode, an insertion block 9 is arranged on the specific cover 3, and after the insertion block 9 is inserted into an injection port of the foaming material injection cavity 9 in an interference manner, the cover 3 can close the port of the open end of the hollow structure 8.

In this embodiment, as shown in fig. 1 to 7, the supporting bar 6 is perpendicular to the head portion 1. As shown in fig. 1 to 7, the supporting strip 6 has three setting modes: the first is to arrange inside the fillable cavity parallel to the handle part 2 (see fig. 4). The second is to be disposed in the fillable chamber perpendicular to the handle portion 2 (refer to fig. 3). And the third is that a vertical supporting strip 6 (refer to fig. 5) is added on the second, and the third structure has higher strength compared with the second structure. The transverse (perpendicular to the handle portion 2) support strip 6 is more suitable for a table tennis bat of the cross-bat type, as shown in fig. 4. The vertical arrangement (parallel to the handle portion 2) of the support strip 6 is more suitable for a straight-bat table tennis bat, as shown in fig. 3 and 5. The reason for this is mainly that the bat habit is different for the straight bat and the horizontal bat, the probability that the end face opposite to the bat handle contacts the table top is increased, and when the bat surface is impacted by the table top, the plurality of support strips 6 can support the bat surface.

In this embodiment, as shown in fig. 1 to 7, the surface of the handle portion 2 is subjected to a secondary injection molding, and a soft polymer thin layer is formed on the surface. Preferably, the surface of the shoulder part of the racket face part 1, namely the surface of the holding position of the fingers, is subjected to secondary injection molding, namely a soft polymer thin layer is formed on the surface of the shoulder part 5. The soft polymer thin layer is made of TPR and/or TPE.

Further, in the present embodiment, as shown in fig. 1 to 7, a rubber installation region where a rubber is originally installed on the surface of the imaging portion 1 is also subjected to secondary injection molding to form the soft plastic layer 4 instead of the rubber. The soft plastic layer 4 can be made of TPR, TPE, PVC (or other materials) or other soft layers.

In this embodiment, as shown in fig. 1 to 7, the injection molded racket plate may be a racket plate such as a table tennis racket, a beach racket or a tennis racket plate.

The utility model discloses a specific example is applied to explain the principle and the implementation mode of the utility model, and the explanation of the above example is only used to help understand the method and the core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present specification should not be construed as a limitation of the present invention.
