The invention has the beneficial effects that: when the adjusting device is used, the adjusting teeth of the adjusting modules are inserted into the grids, then the two adjusting modules are compressed to enable the adjusting springs to be in an extreme compression state, and at the moment, the distances between two adjacent longitudinal strings are pulled to be consistent with the distances between the two corresponding string penetrating holes by the adjusting teeth which are paired pairwise, so that the displacement of the net strings is adjusted.
Drawings
The invention is further described with reference to the following figures and embodiments.
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The racket string modifier shown in fig. 1 comprises two modifier modules 1, 2 arranged in parallel and spaced apart, the modifier modules 1, 2 being generally a single plate, the two modifier modules being movable in opposite directions and being spaced apart in opposite directions. The surface of each adjusting module is provided with adjusting teeth 3 and 4 extending downwards, the adjusting teeth 3 and 4 on different adjusting modules are paired and aligned, and the distance between the two paired adjusting teeth 3 and 4 is equal. The distance between two adjacent adjusting teeth 3, 31 of each adjusting module is also equal.
An adjusting spring 5 is further connected between the two adjusting modules 1, 2, the adjusting spring 5 is compressed by the opposite movement of the two adjusting modules 1, 2, and the adjusting spring 5 is stretched by the opposite separation of the adjusting modules. When the adjusting spring 5 is in a limit compression state, the distance between the two adjusting teeth 3 and 4 which are paired pairwise is the minimum, and the two adjusting teeth 3 and 4 can pull the two staggered string strings which penetrate through the adjacent longitudinal string penetrating holes to the original positions, namely the distance between the opposite side ends of the two adjusting teeth 3 and 4 is equal to the distance between the adjacent longitudinal string penetrating holes of the racket.
In this way, since the distance between the two adjusting teeth 3 and 4 is constant when the two adjusting modules are compressed, a single adjustment of two adjacent net strings is accurate and convenient.
More preferably, more than two adjusting springs 5 are arranged between the two adjusting modules 1 and 2, two ends of each adjusting spring 5 are respectively connected with different adjusting modules, and the adjusting springs 5 are arranged in a balanced manner. Through setting up more than two regulating spring 5, can make two regulating module 1, 2 balanced compression as far as when compressing the regulating module, can not cause the condition that one end compression volume is big, one end compression volume is little.
Preferably, a guide shaft 6 is axially inserted into each adjusting spring 5, and both ends of the guide shaft 6 are respectively inserted into the guide holes 7 of the adjusting module. The outer diameter of the guide shaft 6 is slightly smaller than the inner diameter of the guide hole 7, so that the guide shaft and the guide hole 7 cannot deviate too much, when the two adjusting modules move in opposite translation directions and the adjusting spring 5 is compressed, the guide shaft 6 plays a role in fixing the translation direction, and the adjustment of the net string is more accurate.
Further preferably, the opposite surfaces of each adjusting module are respectively provided with a stepped hole 8, the adjusting spring 5 abuts against the stepped part of the stepped hole 8, and the part with smaller bore diameter in the stepped hole 8 forms the guide hole 7. The depth of the guide hole 7 should be moderate so that the guide shaft 6 does not reach the inner end surface of the guide hole 7 when the adjusting spring 5 is in the extreme compressed state.
Further preferably, the regulator further comprises an arc-shaped fixed surrounding edge 9, wherein the arc-shaped fixed surrounding edge 9 is matched with the frame of the racket and used for abutting against the frame of the racket, and the frame is provided with a transverse string penetrating hole. The fixed surrounding edge 9 is connected with the adjusting module 1 through a pressure adjusting spring 10, the pressure adjusting spring 10 is in a limit compression state, and the distance between the fixed surrounding edge 9 and the adjusting teeth 3 is equal to the distance between the longitudinal string at the most marginal position and the frame of the racket. By arranging the fixed surrounding edge 9, a user can use the regulator to regulate the distance position between the longitudinal string at the most peripheral position and the frame of the racket.
More preferably, more than two pressure regulating springs 10 are arranged between the regulating module 1 and the fixed surrounding edge 9, and the pressure regulating springs 10 are arranged in a balanced manner. Through setting up more than two pressure regulating springs 10, can make fixed surrounding edge 9 and adjusting module 1 balance compression as far as when compression adjusting module 1, can not cause the condition that one end compression volume is big, one end compression volume is little.
Preferably, a guide shaft 11 axially penetrates through each pressure regulating spring 10, one end of the guide shaft 11 is fixedly connected with the fixed surrounding edge 9, and the other end of the guide shaft is inserted into a guide hole 12 of the regulating module 1. The outer diameter of the guide shaft 11 is slightly smaller than the inner diameter of the guide hole 12, so that the guide shaft and the guide hole do not deviate too much, when the adjusting module 1 and the fixed surrounding edge 9 move in opposite translation and the pressure regulating spring 10 is compressed, the guide shaft 11 plays a role in fixing the translation direction, and the adjustment of the net string is more accurate.
The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention.
