[0018] 1-frame, 2-handle, 3-racquet string, 4-connecting arm, 5-hollow area, 6-hollow pipe, 7-cavity. DETAILED DESCRIPTION
[0019] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and can not be understood as the limitation of the utility model.
[0020] In the description of the utility model, it needs to be understood that, the orientation or position relation indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is the orientation or position relation shown based on the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model. In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more than two.
[0021] In the description of the utility model, it needs to be understood that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can also be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0022] Referring to Figure 1 And Figure 2 As shown in FIG. 1, a racket with changeable mass distribution includes a racket frame 1, a racket handle 2 and a racket string 3 worn on the racket frame 1, the racket handle 2 has two connecting arms 4 extending to both sides at one end, the end of the connecting arm 4 away from the racket handle 2 is connected with the racket frame 1, so that a hollow area 5 is formed between the racket frame 1 and the two connecting arms 4, a detachable hollow tube 6 is arranged on each connecting arm 4, and a flowable filler is arranged in the hollow tube 6. During movement, the filler can be instantaneously moved and guided to the direction of hitting the ball according to the force and speed of swinging the racket, so as to increase the swinging gravity of hitting the ball, and the direction kinetic energy of the level instrument is utilized to guide the direction of the racket face when hitting the ball, so that the racket can automatically guide the direction of hitting the ball.
[0023] Specifically, in order to fix the hollow tube 6 on the connecting arm 4, a cavity 7 capable of accommodating the hollow tube is arranged on the outer side of each connecting arm 4, and the hollow tube 6 is detachably arranged in the cavity 7. Of course, the cavity 7 can be designed with or without perforation, which can be determined according to production requirements, as long as the hollow tube 7 can be fixed in the cavity 7. The fixing mode between the hollow tube 6 and the cavity 7 can be adhesive fixing or buckle fixing, as long as the hollow tube 6 is not easy to fall off in the cavity 7, and the specific fixing mode of the hollow tube 6 is not limited.
[0024] In addition, in order to facilitate the filling agent into the hollow tube 6, so that the filling agent can be increased or replaced with different filling agent, the hollow tube 6 of the embodiment includes a hollow tube body and a cover body, the filling agent is arranged in the hollow tube body, and the cover body is sealingly connected with the hollow tube body.
[0025] It can be understood that the cover body and the hollow tube body can be detachably connected, specifically, the cover body and the hollow tube body can be connected through a threaded interface, and a sealing ring is arranged at the connection position, so that the filling agent is not easy to leak, especially when the filling agent is water, the water tightness between the cover body and the hollow tube body is required to be higher. Of course, the filling agent can also be a granular material, such as an hourglass.
[0026] The filling agent of the embodiment can also be other liquids or other granular materials, as long as the filling agent can move instantaneously with the power and speed of the swing when the racket is swung, that is, it can be guided to the direction of the ball.
[0027] It should be noted that in the embodiment, the hollow area 5 is a reverse triangular shape. Of course, the shape of the hollow area 5 is not limited to a reverse triangular shape, and some changes in the shape of the hollow area can be made according to market demand.
[0028] It should be further noted that when using the racket, if it is desired that the center of mass is close to the handle section at the beginning of the swing, and the center of mass is close to the frame at the time of hitting the ball, then at the beginning of the swing, the head frame of the racket is upward, and the filling agent is close to the handle end, and at the beginning of the swing, the center of mass of the racket is close to the handle section, and after the swing, due to the centrifugal force, the filling agent flows to the frame end, so that the center of mass of the racket is close to the frame. This achieves the requirement of changing the mass distribution during the swing from the function.
[0029] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
