[0053] It should be noted that in the present application, the number of adjusting assemblies can be set according to actual conditions, so that the rotating buckle body 100 can control multiple groups of ropes, thereby realizing control of multiple functions of the shoes, and in most cases, the rotating buckle body 100 can be divided into two or three sections, but is not limited to the two or three sections; in the present embodiment, two sections means that the present embodiment can control two groups of ropes, and three sections means that the rotating buckle body 100 of the present embodiment can control three groups of ropes, wherein each group of ropes herein means that there is one or two ropes in each group of ropes, and the one or two ropes move synchronously.

[0054] For example, as shown in Figure 8As shown, when the shoe has two functions, that is, the shoe realizes the sole curvature adjustment through the first group of ropes and realizes the wrapping adjustment of the forefoot part of the sole through the second group of ropes, then the rotating buckle body 100 is two-section, that is, the matching barrel 2 includes two barrel bodies 21, the adjusting assembly has two, and the mounting chassis 1 is divided into two locking areas; when the shoe has three functions, that is, the shoe adds the third group of ropes on the premise of the two functions mentioned above to realize the wrapping adjustment of the instep part of the sole, then the rotating buckle body 100 is three-section, that is, the matching barrel 2 includes three barrel bodies 21, the adjusting assembly has three, and the mounting chassis 1 is divided into three locking areas.

[0055] As shown, Figures 1-7 As shown, the following is described by taking the three-section rotating buckle body as an example. The three winding areas 22 of the matching barrel 2 are respectively provided with two through holes 221, and two adjusting ropes are respectively fixed on each winding area. The first ends of the two adjusting ropes on each winding area pass through the corresponding through holes and are fixed on the inner side of the matching barrel 2 by knotting or other conventional methods, and the two adjusting ropes on each winding area are wound in the same direction in the winding area. In this embodiment, the winding and fixing structure of the two adjusting ropes in each winding area are conventional operations, and therefore will not be described.

[0056] The improved rotating buckle has the following assembly process: the three groups of adjusting ropes are respectively wound in the corresponding winding areas 22, then the matching barrel 2 is installed in the mounting chassis 1, the three adjusting side walls 6 are respectively installed in the corresponding locking areas, at this time, the two spring plates on each clamping piece respectively fix the adjusting side wall 6 on the mounting chassis 1 through the respective limiting clamping blocks 711, so that the three adjusting side walls 6 cannot slide, so that the second limiting pieces 6 on the three adjusting side walls 6 respectively mesh with the three first limiting pieces 213 on the matching barrel 2, then the three switch pieces 3 are respectively inserted into the corresponding separation areas 411 in the rotating seat 41, and the matching sections 33 on the three switch pieces 3 are respectively limited in the corresponding separation areas 411, in each switch piece, the limiting grooves 332 on the matching section 33 are respectively limited and matched with the corresponding limiting protrusions 4111, then the three switch operating pieces 5 are respectively inserted into the corresponding holes 331 and limiting grooves 413, so that the three switch operating pieces 5 are respectively limited at the upper end of the rotating seat 41, then the rotating seat 41 is inserted into the rotating groove 11 of the mounting chassis 1, and the assembly is completed.

[0057] Take one of the adjustment ropes as an example, for the convenience of description, the corresponding barrel 21 of the adjustment rope is taken as barrel one, the switch piece 3 is taken as switch piece one, the limiting piece is taken as limiting piece one, and the adjustment assembly is taken as adjustment assembly one. One set of adjustment ropes has two adjustment ropes. Three smooth areas and three winding rope areas are formed on the cooperation barrel 2. The corresponding winding rope area one is on the barrel one 21. The first tooth part on the switch piece one corresponds to the smooth area one. The specific winding and unwinding process of the utility model is as follows:

[0058] When it is needed to tighten the set of adjustment ropes, downward external force is applied to the switch operating piece one corresponding to the switch piece one, so as to drive the switch piece one to move downward. The cooperation section one of the switch piece one is clamped in the separation area one of the rotating seat 41. At this time, the first tooth part 31 on the switch piece one is engaged with the second tooth part 211 on the barrel one, and each limiting groove 332 on the switch piece one is limited and matched with each corresponding limiting protrusion. The first tooth part 31 on the other two switch pieces 3 which are not pressed downward is located in the corresponding smooth area 212. The top cover 42 or the adjustment assembly is rotated forward, so as to drive the rotating seat 41 to rotate forward. Since the first tooth part on the switch piece one and the second tooth part on the barrel one are engaged with each other, the barrel one is driven to rotate relative to the other two barrels which are not the barrel one. The two adjustment ropes on the winding rope area 22 on the barrel one are synchronously tightened. Since the first limiting piece 213 on each barrel 21 is matched with the ratchet tooth of the second limiting piece 61 on the corresponding adjustment side wall 6, the barrel one can rotate forward, but cannot rotate reversely, so that the adjustment rope set is prevented from being lengthened during the adjustment process. After the tightening is completed, the clamping pieces on each adjustment assembly are adjusted respectively, so that the limiting clamping blocks on the two spring sheets of each clamping piece are respectively abutted against the outer side wall of the corresponding adjustment side wall 6, so as to complete the fixation of each adjustment side wall, and ensure that the cooperation barrel 2 does not move again. Then, the switch operating piece one is used to move the switch piece one upward, so that the second tooth part on the switch piece one is located in the smooth area one, so that the three barrels 21 on the cooperation barrel 2 do not rotate when the top cover 42 or the switch piece rotates, that is, the rope is not tightened again, so as to complete the tightening of the set of adjustment ropes.

[0059] When the adjustment ropes need to be lengthened, outward external forces are applied to the three adjustment side walls 6 respectively, so that the three adjustment side walls 6 slide outward along the clamping pieces respectively, so that the second limiters on the three adjustment side walls 6 are respectively disengaged from the first limiters on the corresponding matching barrels 2, then downward external forces are applied to the switch operating pieces corresponding to the switch pieces one by one, so as to drive the switch pieces one to move downward, the matching sections one of the switch pieces one are clamped in the separation area one of the rotating seat 41, at this time, the first tooth parts 31 on the switch pieces one are engaged with the second tooth parts 211 on the barrel one, the first tooth parts 31 on the other two switch pieces 3 which are not pressed downward are located in the corresponding smooth areas 212 respectively, the top cover 42 or the adjustment assembly is reversely rotated, so as to reversely rotate the rotating seat 41, thereby lengthening the adjustment rope groups in the winding area one, until the required length is reached, the switch operating pieces are used to drive the switch pieces one to move upward relative to the separation area one, so that the first tooth parts on the switch pieces one are located in the smooth area one, then the three adjustment side walls 6 are fixed on the mounting chassis 1 again, and the three clamping pieces are abutted against the outer side walls of the corresponding adjustment side walls 6, so that the lengthening operation of the adjustment ropes is completed.

[0060] It should be noted that the adjustment of the other two groups of adjustment rope groups in the non-winding area one is the same as the above operation process, and will not be described again. In addition, in the tightening process, when two or more groups of adjustment rope groups need to be adjusted, one group of adjustment rope groups is adjusted first, then the next group of adjustment rope groups is adjusted, and then the clamping pieces are locked; in the loosening process, when two or more groups of adjustment rope groups need to be adjusted, the adjustment side walls are unlocked first, then one group of adjustment rope groups is adjusted, then the next group of adjustment rope groups is adjusted, and then the clamping pieces are locked.
