Description

The structure of the badminton racket's grip and its front sleeve

The present invention relates to the structure of a badminton racket, in particular to the structure of a handle and a front sleeve of a badminton racket.

The structure of a badminton racket consists of three parts: the head frame, the middle tube and the grip. The head frame is threaded to form the hitting surface, and the head frame is connected to the grip through the middle tube. The grip of a traditional badminton racket is usually made of stronger and less prone to breaking wood. In addition to the fact that wood is easy to obtain, easy to process, and low in price, wood has a good damping effect, which helps absorb the vibration generated when the racket hits the ball.

In the approved Republic of China New Patent Certificate No. I772198, a badminton racket is proposed, which includes a racket frame, a grip, a front cover and a middle tube. The grip includes a grip portion, a sleeve portion, a fixing member, a plurality of supporting members and an adjustment ring. The grip portion has a front end. The sleeve portion is connected to the front end of the grip portion. The sleeve portion has a first top surface and a first opening, and the first opening is located at the first top surface. The fixing member is connected to the first top surface and extends from the first opening to the inside of the grip portion. The supporting members are arranged in the grip. The supporting members respectively have a front edge and a recess. The front edge is connected to an inner side wall of the sleeve portion, and the recess is located at the front edge. The adjustment ring is arranged in the recess of the supporting members. The front sleeve is mounted on the sleeve portion of the grip. One end of the middle tube is connected to the racket frame, and the other end passes through the first opening to be inserted into the fixing member.

The aforementioned patent technology claims that the force borne by the tube can be dispersed to the fixing parts and the outer adjustment ring, thereby improving the structural strength and allowing the badminton racket to be used in higher-strength hitting types.

However, the badminton racket proposed in the aforementioned patent technology is completely supported by the front cover and the fixing parts to bear the force from the middle tube. The front cover does not bear the force from the middle tube, but only serves as a component to form a complete appearance and has only a simple decorative effect. Therefore, the small section of the middle tube in the front cover has no support at all, resulting in its structural strength being obviously insufficient.

The technical problem to be solved by this new invention is to provide a badminton racket grip and its front sleeve structure, which can improve the structural strength of the joint between the middle tube and the front sleeve of the badminton racket and provide better support for the middle tube.

In order to solve the above technical problems, the structure of the handle and front sleeve of the new badminton racket includes: a main body, a front sleeve mounted on the front end of the main body, and a rear end cover mounted on the rear end of the main body. The interior of the front sleeve is hollow for a middle tube of the badminton racket to pass through; the improved parts are:

An inner core is arranged inside the main body. The inner core is an axially penetrating tubular component, and the middle tube can be inserted into the inner core and fixed therein. The inner wall of the inner core has a plurality of shock-absorbing ribs protruding toward the center. The shock-absorbing ribs extend in a direction parallel to the axial direction of the inner core. The shock-absorbing ribs can press the middle tube. A nose tube is arranged at the front section of the inner core, and the nose tube extends out from the front end of the main body;

The structure of the front sleeve includes: an inner tube and an outer shell. The inner tube is an axially penetrating tubular component. The front end of the inner tube has an opening for the middle tube to pass through. The rear end of the inner tube is inserted into the nose tube of the inner core and connected to the inner core. The inner wall of the inner tube has a plurality of reinforcing ribs protruding toward the center. The reinforcing ribs extend in a direction parallel to the axial direction of the middle tube. The reinforcing ribs can press the middle tube tightly. The outer shell surrounds Located on the outer periphery of the inner tube, the front end of the outer shell is integrally connected to the front end of the inner tube. The outer shell is a tapered tube that gradually expands from the front end to the rear end. The front section of the main body is tapered. The outer shell is a matching tapered shape that can be sleeved on the front section of the main body. The front sleeve is also equipped with a locking bolt that can pass through the outer shell and the front section of the main body and then penetrate into the inner core. The locking bolt is used to lock the middle tube that penetrates into the inner core.

As a preferred embodiment of the structure of the handle and front sleeve of the new badminton racket, the outer side of the inner core has a plurality of ribs protruding outward along the radiation direction, and the edges of the ribs in the extension direction are connected to the inner wall surface of the main body.

Preferably, the inner wall surface of the front section of the main body is formed with an engagement groove at a position corresponding to the ribs, and the ribs near the front end of the inner core can be respectively embedded in the engagement groove.

Preferably, the edge of the rib in the extension direction is connected to the inner wall of the main body by ultrasonic welding or adhesive.

As a preferred embodiment of the structure of the handle and the front sleeve of the new badminton racket, the inner diameter of the nose tube is larger than the inner diameter of the inner core, and the inner diameter of the inner tube is consistent with the inner diameter of the inner core.

The advantages and effects of this new type are: the middle tube of the badminton racket can be firmly fixed to the inner core in the main body, and the inner tube of the front sleeve and the nose tube of the inner core are plugged together to improve the strength of the structure and provide better support for the middle tube, forming a reliable and high-strength structure at the joint between the middle tube and the front sleeve of the badminton racket.
