[0007] The flexible outer wrapping effect of the elastic tension of the racket string is realized by the gap fit between the racket string and the threading hole, and the close inner pad effect of the elastic tension of the racket string is realized by the interference fit between the racket string and the damping bridge.
[0008] Preferably, the nail cap, nail barrel, reinforcement part, and the rear side of the threading hole of the damping bridge are fixed with a reinforcement part, the nail barrel and the nail cap behind the reinforcement part are coaxial, and the nail cap, nail barrel, reinforcement part, and damping bridge are integrally formed by injection molding.
[0009] The damping bridge and the reinforcement part are integrally formed by injection molding, and the reinforcement part, the nail cap and the nail barrel are integrally formed by injection molding to form a double-linked nail for wire protection that acts as a series fixation on the damping bridge, so that some long components and some short components of the nail barrel are adapted to the placement of the frames on both sides of the lower semicircular handle end of the racket.
[0010] Preferably, the damping bridge comprises a damping petal, a connecting bridge body, and a wire hole cap.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figures 1-4 The utility model provides a double-connected nail for string protection of a racket, including a threading hole 4, a damping bridge 5, and a racket string 6. The threading hole 4 is arranged inside the left and right ends of the damping bridge 5 in an opposite manner, and the outer surface of the threading hole 4 and the inner surface of the damping bridge 5 are integrally formed by injection molding.
[0025] Due to the elastic tension wrapping structure function of the string guard nails, there are defects in protecting the racket strings.
[0026] The racket string 6 is a concave arc surface built into the damping bridge 5. The end and body of the racket string 6 are U-shaped and pass through the threading hole 4 in sequence from the left and out from the right with a clearance fit. The racket string 6 passes through the threading hole 4 and the arc surface of the inner cavity of the damping bridge 5 with an interference fit.
[0027] It should be noted that the flexible outer wrapping effect of the elastic tension of the racket string 6 is generated through the clearance fit between the racket string 6 and the threading hole 4, and the tight inner padding effect of the elastic tension of the racket string 6 is generated through the interference fit between the racket string 6 and the damping bridge 5, thereby improving the elastic tension wrapping structural function of the wire protection nail and further enhancing the comprehensive protection of the racket string.
[0028] When the athlete swings the racket, and the racket wears against obstacles such as the ground, the damping friction force of the damping bridge 5 elastically unloads the external friction pressure of the racket, and the racket string 6 is brought into a damage-free state through the comprehensive protection of the elastic tension wrapping structure of the damping bridge 5, avoiding the problem of racket string 6 breakage and extending the service life and protection life of the racket string 6.
[0029] Because the equal length nail barrel 2 of the existing double nails for protecting the string is assembled in the racket, the verticality of the racket string 6 is unstable and the string distance angle is skewed due to the frame restriction and pressure, resulting in defects such as the nail head oblique end and the racket string 6 inclined surface.
[0030] The nail cap 1, nail tube 2, reinforcement part 3, and the rear side of the threading hole 4 of the damping bridge 5 are fixed with a reinforcement part 3. The axes of the nail tube 2 and the nail cap 1 on the rear side of the reinforcement part 3 are collinear. The nail cap 1, nail tube 2, reinforcement part 3, and damping bridge 5 are integrally formed by injection molding. There are two reinforcement parts 3, which are respectively perpendicular to the damping bridge 5 to form a concave-shaped integrated structure.
[0031] It should be noted that the damping bridge 5 and the reinforcement part 3 are integrally formed by injection molding, so that the reinforcement part 3, the nail cap 1 and the nail tube 2 are integrally formed by injection molding to form a double-linked nail for wire protection in series fixing on the damping bridge 5, so that some long components and some short components of the nail tube 2 are adapted to the placement of the frames on both sides of the lower semicircular handle end of the racket. Through the mutual perpendicularity of the reinforcement part 3 and the damping bridge 5, the stability of the verticality of the racket wire protection straightening net formed by the two right-angled triangles of the left and right reinforcement parts 3 and the damping bridge 5 is promoted.
[0032] When the athlete swings the racket, the reinforcement part 3 adapts to the racket frame between the damping bridge 5 and the nail tube 2 of inconsistent length to form a strong vertical angle correction racket string 6 support and anti-deformation pressure bearing effect.
[0033] Because the double nails of the racket string guard do not fully protect and wrap the racket string 6.
[0034] See also Figures 1-4The present invention provides a double-connected stringing nail for a racket. The damping bridge 5 comprises a damping petal 51, a connecting bridge 52, and a string hole cap 53. The string hole 4 comprises two holes, with the connecting bridge 52 integrally extending through the middle. The connecting bridge 52 is tightly attached to the damping petal 51 on the top side of the middle hole. The outer surface of the string hole 4 is covered with a string hole cap 53. The damping petal 51, connecting bridge 52, and string hole cap 53 are integrally molded by injection molding.
[0035] It should be noted that the inner side of the damping petal 51 forms a cushioning effect on the racket string 6 when tension is tightened inside the racket surface, and the connecting bridge body 52 and the string hole cap 53 form a wrapping effect on the racket string 6 when tension is tightened inside the racket surface, so that the double-linked nails of the racket string guard can fully wrap and protect the inner padding of the racket string 6.
[0036] When the athlete swings the racket and the racket wears against obstacles such as the ground, the damping friction force of the damping petal 51 elastically unloads the external friction pressure of the racket, and the racket string 6 is made intact by the comprehensive protection of the elastic tension wrapping structure connecting the bridge body 52 and the string hole cap 53, avoiding the problem of racket string 6 breakage and extending the service life and protection life of the racket string 6.
[0037] Because the equal length nail barrel 2 of the existing double nails for protecting the string is assembled in the racket, the horizontal and vertical interweaving of the string net will be unstable and the line distance angle will be skewed due to the restriction of the frame, resulting in the defects of the nail head oblique end and the racket string 6 inclined surface.
[0038] The racket string 6 enters the short nail tube 2 downward on the left side and passes through the threading hole 4 and the connecting bridge body 52. The racket string 6 then enters the long nail tube 2 upward on the right side through the threading hole 4 and penetrates the racket surface. The racket string 6 is symmetrically arranged in the racket surface with the nail tube 2 being short on the left and long on the right, or long on the left and short on the right, and is interwoven into a net surface for receiving the badminton.
[0039] It should be noted that the racket strings 6 are pulled by part of the long components and part of the short components of the nail tube 2 to adapt to the arc surface of the frame on both sides of the lower semicircular handle end of the racket, so as to correct the verticality of the horizontal and vertical interweaving of the wire net, make the horizontal and vertical interweaving of the wire net horizontally and vertically, and tighten the tension and elastic coordination of the net surface.
[0040] When the athlete swings the racket, the horizontal and vertical touch of the badminton hitting the string net will give the player effective tension feedback and positive force guidance, and the racket's double-linked string nails can achieve a good bite and wrapping protection effect on the racket string 6.
[0041] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the scope of protection of the present application.
