Description

Novel single-particle nail for badminton racket

Technical Field

The utility model relates to the field of sports equipment, especially, relate to a novel racket single grain nail.

Background

At present, the structure of the badminton racket basically comprises a racket frame body, a handle is connected on the racket frame body, string holes are arranged on the outer edge of the racket frame body, and strings penetrate through the string holes arranged on the racket frame body and are longitudinally staggered in the area surrounded by the racket frame body to form a racket net. In order to reduce the exposure of the net strings outside the outer edge of the racket frame body and avoid collision and friction with the ground or a ball in violent sports, a groove with the depth larger than the diameter of the net strings is usually arranged on the outer edge of the racket frame body along the string hole connecting line, the arrangement of the groove makes the peripheral edge of the string hole difficult to process.

At present, the connection auxiliary material part with the buffering function is arranged in the string hole, so that the direct contact between the string and the racket frame is avoided, the acting force between the string and the racket frame is buffered, the service life of the string is prolonged, and the connection auxiliary material part is as the Chinese patent application number: 201721402664.6 discloses a badminton racket side frame sheath and a badminton racket, the shape of the side frame sheath is adapted to the side of the side frame of the badminton racket, the bottom of the side frame sheath is provided with a bottom edge adapted to the side frame of the badminton racket, and the top of the side frame sheath is provided with a wire casing and at least one wire hole. During installation, the line holes in the side frame sheaths are respectively matched with the line holes in the frame of the badminton racket, so that the side frame sheaths are required to be high in machining precision, the matching consistency of the frame of the badminton racket is achieved, and the production cost is greatly improved; if the connecting auxiliary material part with the tubular structure is embedded into the string holes of the racket frame body, the net strings penetrate through the connecting auxiliary material part with the tubular structure to avoid direct contact with the racket frame body, and although the processing cost is reduced, when the badminton racket is stressed in use, the net strings are easy to break or loosen, so that the using effect of the badminton racket is greatly reduced.
