Abstract

The utility model relates to an improved structure for a racket which comprises a head frame, a grab handle and a connect part connected between the grab handle and the head frame, wherein, the top part of the outer edge of the head frame is covered with a sheath, the inner edge frame wall and the outer edge frame wall of the head frame are respectively provided with a plurality of round angle lugs, the outer side wall of the sheath is respectively formed with a groove used for receiving racket lines, and the bottom wall of the groove is formed with openings corresponding to the round angle lugs arranged on the outer edge wall of the head frame; the round angle lugs can be projected to the groove through the corresponding openings, and the inner part of the groove is formed with line eyes corresponding to line holes arranged in the head frame. Each line hole arranged in the head frame and the adjacent round angle lug can provided a smooth line guiding path for the racket line passing through the line hole.

Description

Improved structure for racket

The utility model relates to a kind of racket improvement structure of clapping line of protecting.

All be equiped with on the general racquet frame by what soft elastic material was made and protect the lines nail, directly contact and be worn with the frame part of avoiding clapping line and hard and having a sharp edges.But protect the manufacturing of lines nails and need can roll up the cost of racket with artificial installation, protect the lines nail so remove on the frame, one reaches to being that these those skilled in the art are desired.

The purpose of this utility model is to provide a kind of improvement structure of racket, and it need not installed and protect the lines nail, and saves the manufacturing and the installation cost of the costliness of protecting the lines nail, and said shortcoming above having overcome.

The utility model provides a kind of improvement structure of racket to comprise a frame, a lever and is connected in a junction between a frame and lever.The outer rim top of frame covers a sheath in proper range, wear the bat line with interleaved mode in length and breadth via each line hole on the frame, the inner edge frame wall of frame is provided with a plurality of fillet projections, the outer rim frame wall of frame also is provided with a plurality of fillet projections, respectively form a groove in the lateral wall of sheath and clap line in order to admit, form in the diapire of this groove corresponding to each opening of each fillet projection of frame outer rim frame wall, these fillet projections can be protruded in this groove via these openings, also form in the groove and a frame on each line hole respectively pass through threaded eye accordingly.Each line hole on this frame and contiguous fillet projection provide slick and sly path of navigation for the bat line of wearing cable-through hole, although make not use and protect the lines nail on the general racket, and also unlikely generation is clapped line by the situation of the sharp edges in line hole wearing and tearing.

Below in conjunction with drawings and Examples describe in detail the utility model as after, in these accompanying drawings:

Fig. 1 is a three-dimensional combination schematic diagram, shows racket improvement structure of the present utility model;

Fig. 2 shows the sheath in the racket improvement structure shown in Figure 1;

Fig. 3 shows the radiussed protuberance that forms on the structurally improved frame outer rim of this racket frame wall;

Fig. 4 is the sheath cutaway view along IV among Fig. 2-the IV line is got; And

Fig. 5 is along the cutaway view that V among Fig. 1-the V line is got, and shows to clap the situation that line passes a frame.

See also each accompanying drawing, the improvement of racket of the present utility model structure comprises a frame 1, a lever 2 and is connected in a frame 1 and a junction 3 of 2 of levers.The outer rim top of frame 1 also can optionally cover sheath 11 in proper range, wear via each line hole 12 with interleaved mode in length and breadth on the frame 1 and clap line 13, the inner edge frame wall of frame 1 is provided with fillet projection 4, follow closely (not shown) in order to economize the lines that protect that remove in the racket commonly used, the utility model more adds fillet projection 14 as shown in Figure 3 on the outer rim frame wall of a frame 1, each fillet projection 4 and 14 outer surface all are smooth curved surfaces, form one on the lateral wall of sheath 11 and admit recess or groove 15, clap line 13 in order to admit, protrude in beyond the sheath 11 in order to avoid clap line 13, form each opening 16 on the diapire of groove 15 corresponding to each projection 14, each projection 14 is projected in the groove 15 via corresponding each opening 16, in the groove 15 and form and a frame 1 on each line hole 12 corresponding each line eye 17.Each line hole 12 and contiguous fillet projection 4,14 provide slick and sly path of navigation for the bat line of wearing cable-through hole 12, make it as shown in Figure 5, when passing in the line hole 12 when the guiding of clapping line 13 mats one or two fillet projections 4,14, clapping line 13 can not contact with the sharp edges in a frame 1 center line hole 12, although thereby do not use and protect the lines nail on the racket commonly used, also unlikely generation is clapped line 13 by the situation of the sharp edges in line hole 12 wearing and tearing.

Be adjacent to arbitrary line hole 12 on the inner edge frame wall of frame 1 and the outer rim frame wall whether the threading mode that fillet projection 4,14 is decided by racket need be set, just may produce and clap line 13 in that fillet projection 4 or 14 is not set, all fillet projection 4 or 14 need be set by the place of the sharp edges in line hole 12 wearing and tearing.

Claims
