[0031] Furthermore, in this embodiment, in the above-mentioned mating cylinder 2, the rotation structure between each two adjacent cylinders 21 can adopt an existing conventional rotation structure, for example, the side facing each other between the two adjacent cylinders 21 is the mating side, and the mating sides of the two cylinders 21 are respectively provided with annular grooves and annular protrusions for sliding fit.

[0032] Specifically, if Figure 2-3 As shown, each of the switch components 3 includes a flat-pressing section 32 and a matching section 33 connected in one piece. Each flat-pressing section 32 is sequentially arranged at intervals along the circumference of the matching tube 2, and each flat-pressing section 32 is spliced ​​together to form a petal or circular shape; each matching section 33 is arranged along the axial direction of the matching tube 2, and the upper end of each matching section 33 is respectively connected to the corresponding flat-pressing section 32 in one piece. Preferably, the lengths of each matching section 33 are different, and each of the second teeth 31 is respectively arranged at the lower end of the outer side wall of the corresponding matching section 33, so that each second tooth 31 is arranged in an interlaced manner.

[0033] like Figure 2 As shown and Figure 4As shown, the above-mentioned mounting base 1 is rotatably mounted with a rotating member 4, the rotating member includes a rotating seat 41, the rotating seat 41 is coaxially arranged with the matching cylinder 2, and the rotating seat 41 is separated by at least two partition areas 411, the number of the partition areas 411 is the same as the number of the adjustment components, each switch member 3 is arranged in the partition area 411 in a manner that it can limit and synchronize with the corresponding partition area 411 or be separated from each other in their respective actions. Specifically, each partition area 411 is provided with a plurality of limiting convex strips 4111, each limiting convex strip 411 is divided into two groups, and the two groups are arranged on both sides of the partition area 411, and the inner side wall of each switch member 3 is respectively provided with limiting grooves 332 corresponding to each limiting convex strip 411 on the corresponding partition area 411, and each limiting convex strip 411 and each limiting groove 332 are respectively limited and matched. For example, in this embodiment, the limiting convex strips 4111 are used to limit the movement of the corresponding partition area 411. Taking four limiting convex strips as an example, the four limiting convex strips are grouped in pairs and are arranged on both sides of the partition area 411. The two limiting convex strips 4111 in the same group are arranged at intervals along the axial direction of the matching tube 2. The matching section 33 of the switch member 3 corresponds to each limiting convex strip 4111 and respectively opens a limiting groove 332. Each limiting convex strip 4111 and each limiting groove 332 are respectively matched in a one-to-one limiting manner. In order to allow the limiting convex strip 4111 to smoothly detach from the corresponding limiting groove 332 under the action of external force, the cross-sections of the limiting convex strip 4111 and the limiting groove 332 are both semicircular.

[0034] During assembly, the lower end of each mating section 33 is inserted into the corresponding partition area 411 and cooperates with the corresponding partition area 411. At this time, each flat pressing section 32 is located on the upper side of the rotating seat 41, and a gap is left between each flat pressing section 32 and the upper end of the rotating seat 41.

[0035] Furthermore, in this embodiment, the rotating structure of the rotating seat 41 rotatably mounted on the mounting base 1 can adopt a conventional rotating structure, for example, a rotating shaft 412 is integrally connected to the middle position of the bottom of the rotating seat 41, a rotating groove 11 is provided in the middle position of the mounting base 1, and the rotating shaft 412 and the rotating groove 11 are rotatably matched; for another example, a rotating groove 11 is provided in the middle position of the mounting base 1, a bearing is embedded in the rotating groove 11 of the mounting base 1, and a rotating shaft is integrally connected to the middle position of the bottom of the rotating seat 41, and the rotating shaft is inserted into the bearing. Preferably, a concave cavity for accommodating the bottom of the rotating seat 41 is also provided at the bottom of the mounting base 1, and a sliding groove arranged along the circumferential direction is provided on the concave cavity, and an annular convex portion is provided at the bottom of the rotating seat 41 corresponding to the position of the sliding groove, so that the rotating seat 41 can rotate smoothly.

[0036] Preferably, the rotating member 4 further includes a top cover 42, a mounting hole is provided in the middle of the top cover 42, and the upper end of the rotating seat 41 is tightly sleeved in the mounting hole of the top cover 42 to increase the aesthetics of the rotating buckle body 100; wherein, when the rotating member 4 is installed on the mounting base 1, the top cover 42 is overlapped at the upper end of the mounting base 1.

[0037] Furthermore, the above-mentioned matching tube 2 is located in the mounting base 1, and the matching tube 2 and the mounting base 1 are coaxially arranged. The mounting structure of the matching tube 2 is that the lower end face of the matching tube 2 is rotatably mounted on the bottom surface of the mounting base 1, and the rotation structure of the matching tube 2 can adopt the existing conventional rotation structure.

[0038] like Figure 2 As shown and Figure 5 As shown, each of the above-mentioned adjustment components also includes a switch operating member 5. In this embodiment, the switch operating member 5 is used to control the upward movement or downward pressure of the switch member. Each switch operating member 5 has the same control structure for its own switch member, so one group is taken as an example for description. The specific structure is: an opening 331 is opened on the upper part of the matching section 33 on the switch member 31, and the hole wall of the opening 331 is arranged to be inclined downward toward the inner side, and the aperture of the opening 331 is arranged to be gradually reduced toward the inner side, and the inner side here refers to the axis of the rotating buckle body 11. The position is the inner side, and the opposite side is the outer side; a limiting groove 413 is provided at the upper part of the rotating seat 41 corresponding to the position of the opening 331, and the limiting groove 413 is arranged along the axial extension of the matching cylinder 2, and the limiting member 5 is inserted into the opening 331 and the limiting groove 413 in sequence, and to ensure that the limiting member 5 is not easy to loosen, the inclined section 52 of the limiting member 5 is adapted to the limiting groove 413; wherein, when the switch member 3 is assembled on the rotating seat 41, the opening 331 is located on the upper side of the rotating seat 41, that is, the opening 331 is located at the position of the above-mentioned gap.

[0039] Preferably, the above-mentioned switch operating member 5 is an operating handle, which includes a flat section 51 and an inclined section 52 that are integrally connected. The inclined section 52 is arranged to be inclined downward in a direction away from the flat section 51, and the end of the inclined section 52 is set as a limiting portion 521. The limiting portion 521 is limited and cooperates with the above-mentioned limiting groove 413, and the width of the inclined section 52 is gradually reduced along the inner direction, so that after the switch operating member 5 is inserted into the opening 331, the inclined section 52 is clamped at the inner hole mouth of the opening 331, and the limiting portion 521 is limited in the limiting groove 413; in this way, the corresponding switch member 3 is driven to move upward by the upward movement of the switch operating member 5, and the corresponding switch member 3 is driven to move downward by the downward movement of the switch operating member 5.

[0040] In this embodiment, the assembly process between the switch member, the rotating seat and the switch operating member is as follows: the switch member is inserted into the partition area of ​​the rotating seat 41, at which time the matching section of the switch member is limited in the corresponding partition area, and then the switch operating member 5 is inserted into the corresponding opening 331 and the limiting groove 413 in turn, so that the end of the inclined section of the switch operating member 5 is clamped in the limiting groove, at this time, each first tooth portion is respectively engaged with the corresponding second tooth portion; when each first tooth portion is respectively located in the corresponding smooth area, the matching section on each switch member 3 is respectively located in the corresponding partition area, at this time, the limiting convex strip on the lower side of each partition area 411 is limited and matched with the corresponding limiting groove on the upper side, and the above state is the normal state of the rotating buckle body 100.

[0041] like Figure 2 As shown and Figure 7 As shown, each of the above-mentioned adjustment components also includes an adjustment side wall 6, and each of the adjustment side walls 6 is arranged in sequence along the circumference of the mounting base 1, and each of the adjustment side walls 6 is installed on the mounting base 1 in a direction that can deviate from the axis of the matching tube 2, and each of the adjustment side walls 6 is respectively provided with one or two through holes 64, and the number of through holes 64 on each adjustment side wall matches the number of adjustment ropes in the corresponding adjustment rope group, and the adjustment rope groups on each winding area pass through the through holes of the corresponding adjustment side wall 6, so that each adjustment rope group is led out; wherein, the inner side walls of each adjustment side wall 6 are respectively provided with a second limiting member 61, and the second limiting members 61 are arranged in an alternating manner, and the second limiting members 61 are respectively matched with the first limiting members one-to-one; preferably, each second limiting member 61 and each first limiting member 213 are ratchet teeth, and each first limiting member 61 is respectively meshed with the corresponding first limiting member 213.

[0042] Furthermore, the above-mentioned mounting base 1 is respectively provided with at least two base side walls 12, and the mounting base 1 is respectively formed with locking areas through each base side wall 12, and each locking area is respectively arranged one-to-one with each adjusting side wall 6. The mounting structure of each adjusting side wall 6 is the same, so one of them is taken as an example for explanation, and limiting lugs 62 are respectively extended from both side edges of the upper side of the adjusting side wall 6, and the two limiting lugs 62 are arranged back to back, and two limiting recesses 12 are respectively arranged at the upper ends of the two base side walls 12 adjacent to the adjusting side wall 6, and the two limiting lugs 62 and the two limiting recesses 12 are respectively matched one-to-one.

[0043] Further speaking, Figure 7 As shown, in each of the above-mentioned adjustment components, the adjustment component also includes a clamping member, which includes two spring pieces 71, both of which are in the shape of strips, and the two spring pieces 71 are arranged back to back, the first ends of the two spring pieces 71 are integrally connected to the bottom of the mounting base 1, and extend to the middle position adjacent to the mounting base 1, the second ends of the two spring pieces 71 respectively extend out of the adjusting side wall 6 through the openings of the adjusting side wall 6, that is, the adjusting side wall 6 is provided with an opening 63, the opening 63 is a square opening, and the two spring pieces 71 are provided with limiting blocks 711, and the two limiting blocks 711 can respectively abut and cooperate with the outer side walls of the adjusting side wall 6; preferably, the second ends of the above-mentioned two spring pieces 71 are jointly limited on the same limiting piece 73, and the limiting piece 73 is provided with a mouth-shaped opening, so that when the corresponding rope is lengthened, the corresponding two spring pieces 71 can be limited.

[0044] It should be noted that, in the present invention, the number of adjustment components can be set according to actual conditions so that the rotating buckle body 100 can control multiple groups of ropes, thereby realizing the control of multiple functions of the shoes. In most cases, the rotating buckle body 100 can be divided into two sections or three sections, but is not limited to the two sections or three sections; in this embodiment, the two-section type means that the present embodiment can control two groups of ropes, and the three-section type means that the rotating buckle body 100 of this embodiment can control three groups of ropes, wherein each group of ropes here means that there are one or two ropes in each group of ropes, and one or two ropes move synchronously.

[0045] For example, Figure 8As shown, when the shoe has two functions, that is, the shoe adjusts the warpage of the sole through the first group of ropes, and adjusts the coverage of the forefoot part of the sole through the second group of ropes, then the rotating buckle body 100 is a two-stage type, that is, the matching tube 2 includes two cylinders 21, there are two adjustment components, and two locking areas are separated on the mounting base 1; when the shoe has three functions, that is, the shoe is added with a third group of ropes on the premise of the aforementioned two functions to adjust the coverage of the instep part of the sole, then the rotating buckle body 100 is a three-stage type, that is, the matching tube 2 includes three cylinders 21, there are three adjustment components, and three locking areas are separated on the mounting base 1.

[0046] like Figure 1-7 As shown, the following description will be made taking the three-section rotating buckle body as an example. The three rope winding areas 22 of the above-mentioned matching tube 2 are respectively provided with two through holes 221, and the two through holes 221 on each rope winding area are respectively fixed with an adjustment rope, and the first ends of the two adjustment ropes on each rope winding area pass through the corresponding through holes, and are respectively fixed to the inner side of the matching tube 2 by conventional methods such as knotting, and the two adjustment ropes on each rope winding area are respectively wound in the rope winding area in the same direction. In this embodiment, the winding and fixing structure of the two adjustment ropes in each rope winding area are existing conventional operations, so they will not be described in detail.

[0047] The present invention discloses an improved rotary buckle, wherein the specific assembly process is as follows: the three groups of adjustment ropes are respectively wound in the corresponding rope winding areas 22, and then the matching tube 2 is installed in the mounting base 1, and the three adjustment side walls 6 are respectively installed in the corresponding locking areas. At this time, the two spring pieces on each clamping member respectively fix the adjustment side walls 6 on the mounting base 1 through their respective limit clamping blocks 711, so that the three adjustment side walls 6 will not slide, so that the second limit members 6 on the three adjustment side walls 6 are respectively engaged with the three first limit members 213 on the matching tube 2, and then the three switches are locked. The parts 3 are respectively inserted into the corresponding partition areas 411 in the rotating seat 41, and the matching sections 33 on the three switch parts 3 are respectively limited in the corresponding partition areas 411. In each switch part, the limiting grooves 332 on the matching sections 33 are respectively limited and matched with the corresponding limiting convex strips 4111, and then the three switch operating parts 5 are respectively inserted into the corresponding openings 331 and the limiting grooves 413, so that the three switch operating parts 5 are respectively limited at the upper end of the rotating seat 41, and then the rotating seat 41 is inserted into the rotating groove 11 of the mounting base 1 to complete the assembly.

[0048] Take one group of adjustment ropes as an example for description. For the convenience of description, the cylinder 21 corresponding to the adjustment ropes is cylinder one, the switch member 3 is switch member one, the limit member is limit member one, the adjustment assembly is adjustment assembly one, and one group of adjustment ropes has two adjustment ropes. Among them, three smooth areas and three rope winding areas are formed on the matching cylinder 2. The one on the cylinder one 21 corresponds to the rope winding area one, and the first tooth portion on the switch member one corresponds to the smooth area one. The specific retraction and extension process of the present invention is as follows: When it is necessary to tighten the group of adjustment ropes, a downward external force is applied to the switch operating member 1 corresponding to the switch member 1 to drive the switch member 1 to move downward, and the matching section 1 of the switch member 1 is fixed in the partition area 1 of the rotating seat 41. At this time, the first tooth portion 31 on the switch member 1 is meshed with the second tooth portion 211 on the cylinder body 1, and at the same time, the limiting grooves 332 on the switch member 1 are respectively matched with the corresponding limiting convex strips, and the first tooth portions 31 on the other two switch members 3 that are not pressed downward are respectively located in the corresponding smooth areas 212, and the top cover 42 or the adjustment component is rotated forward to drive the rotating seat 41 to rotate forward. Since the first tooth portion on the switch member 1 and the second tooth portion on the cylinder body 1 are meshed with each other, the cylinder body 1 is driven to rotate relative to the other two cylinders other than the cylinder body 1, so that the two teeth of the rope winding area 22 on the cylinder body 1 are The adjusting rope is tightened synchronously, and because the first limiting piece 213 on each cylinder 21 cooperates with the ratchet teeth of the second limiting piece 61 on the corresponding adjusting side wall 6, the cylinder 1 can rotate in the forward direction but not in the reverse direction, thereby avoiding the lengthening of the adjusting rope group during the adjustment process. After the tightening is completed, the clamping pieces on each adjusting component are adjusted respectively, so that the limiting blocks on the two spring pieces on each clamping piece are respectively abutted against the outer wall of the corresponding adjusting side wall 6, thereby completing the fixation of each adjusting side wall and ensuring that the matching cylinder 2 no longer moves. Then, the switch operating piece 1 is used to move the switch piece 1 upward so that the second tooth portion on the switch piece 1 is located in the smooth area 1, so that when the top cover 42 or the switch piece rotates, the three cylinders 21 on the matching cylinder 2 no longer rotate, that is, the rope is no longer tightened, thereby completing the tightening of the group of adjusting ropes.

[0049] When it is necessary to lengthen the adjustment rope, an outward external force is applied to the three adjustment side walls 6 respectively, so that the three adjustment side walls 6 slide outward along their respective clamping parts, so that the second limiting parts on the three adjustment side walls 6 are respectively disengaged from the first limiting parts on the corresponding matching cylinder 2, and then a downward external force is applied to the switch operating part 1 corresponding to the switch part 1 to drive the switch part 1 to move downward, and the matching section 1 of the switch part 1 is clamped in the partition area 1 of the rotating seat 41. At this time, the first tooth portion 31 on the switch part 1 is meshed with the second tooth portion 211 on the cylinder body 1, and the other two non-pressed parts are engaged with each other. The first teeth 31 on each switch member 3 are respectively located in the corresponding smooth area 212, and the top cover 42 or the adjustment component is rotated in the opposite direction to drive the rotating seat 41 to rotate in the opposite direction, so as to lengthen the adjustment rope group in the rope winding area 1. After the required requirements are met, the switch operating member 1 is used to drive the switch member 1 to move upward relative to the partition area 1, so that the first teeth on the switch member 1 are located in the smooth area 1, and then the three adjustment side walls 6 are re-fixed on the mounting base 1 respectively, and then the three clamping members are respectively abutted against the outer side walls of the corresponding adjustment side walls 6 to complete the operation of lengthening the adjustment rope.

[0050] It should be noted that the adjustment of the other two groups of adjustment ropes on the non-roping area 1 is the same as the above operation process, so it will not be described in detail. In addition, during the tightening process, when two or more groups of adjustment ropes need to be adjusted, one group of adjustment ropes is adjusted first, and then the next group of adjustment ropes is adjusted. After each group of adjustment ropes is adjusted, each clamping part is locked; during the loosening process, when two or more groups of adjustment ropes need to be adjusted, each adjustment side wall is unlocked first, and then one group of adjustment ropes is adjusted, and then the next group of adjustment ropes is adjusted. After each group of adjustment ropes is adjusted, each clamping part is locked.

[0051] In the present invention, the material of the rotating buckle body 100 is the same as that of conventional rotating buckles, such as plastic.

[0052] The above description is only a preferred embodiment of the present embodiment, and all equivalent changes and modifications made within the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
