When existing drawstring buckles are used in shoes, they all rely on springs to secure the drawstring. However, these springs not only increase manufacturing difficulty but are also prone to rusting or loss of elasticity. Therefore, the inventor believed these shortcomings could be improved and, through dedicated research and the application of scientific principles, finally proposed this invention with a rational design that effectively overcomes these deficiencies. The present invention provides a shoe, a cord buckle assembly, and a single-piece adjustment buckle, which can effectively improve the defects that may occur in existing cord buckles. This invention discloses a shoe, comprising: a shoe body; a strap threaded onto the shoe body, the strap having two adjustment sections extending out of the shoe body; and a single-piece adjustment buckle having a first plate and a second plate located on opposite sides, and an inlet end and an outlet end located at opposite ends of the first plate; wherein the single-piece adjustment buckle is disposed on the shoe body with the first plate, and the single-piece adjustment buckle has two threading channels formed inside, each threading channel having: a receiving groove having an inlet at the inlet end and an outlet recessed in the first plate and adjacent to the outlet end; and a positioning groove located at the outlet end and communicating with the receiving groove; wherein the opening of the positioning groove communicates with the outlet, and the width of the positioning groove extends from the opening towards... The cord tapes towards the bottom of the groove, gradually narrowing in a direction towards the fixing point. Each cord threading channel defines a cord entry direction between the cord inlet and the positioning groove, and the fixing direction forms an angle between 100 and 170 degrees with the cord entry direction. Each adjustable segment of the cord can pass through the receiving groove from the cord inlet of one of the cord threading channels and exit the receiving groove from the cord outlet, thus being in an adjustable state. When any adjustable segment of the cord is in the adjustable state, the adjustable segment can move within the receiving groove of the corresponding cord threading channel, and the adjustable segment can also be pulled away from the shoe body to embed itself from the opening of the positioning groove of the corresponding cord threading channel toward the bottom of the groove, and then be compressed and deformed to be fixed in the positioning groove. This invention also discloses a rope buckle assembly, comprising: a single-piece adjusting buckle having a first plate and a second plate located on opposite sides, and an inlet end and an outlet end located at opposite ends of the first plate; wherein the single-piece adjusting buckle has at least one rope-passing channel formed inside, having: a receiving groove having an inlet at the inlet end and an outlet recessed in the first plate and adjacent to the outlet end; and a positioning groove located at the outlet end and communicating with the receiving groove; wherein the opening of the positioning groove communicates with the outlet, and the... The positioning groove has a gradually narrowing width from the opening towards the bottom of the groove in a rope-fixing direction; wherein at least one rope-threading channel defines an entry direction between the rope inlet and the positioning groove, and the rope-fixing direction forms an angle between 100 degrees and the rope inlet direction; and a rope has an adjustment section for passing through the receiving groove from the rope inlet and exiting the receiving groove from the rope outlet, in an adjustable state; wherein, when the adjustment section of the rope is in the adjustable state, the adjustment section can move within the receiving groove, and the adjustment section can also be inserted from the opening of the positioning groove towards the bottom of the groove and deformed under pressure to be fixed in the positioning groove. This invention also discloses a single-piece adjustment buckle, comprising: a first plate and a second plate, respectively located on opposite sides of the single-piece adjustment buckle; an inlet end and an outlet end, respectively located at both ends of the first plate; and at least one threading channel formed inside the single-piece adjustment buckle and having: a receiving groove having an inlet at the inlet end and an outlet recessed in the first plate and adjacent to the outlet end; and a positioning groove located at the outlet end and communicating with the receiving groove; wherein the opening of the positioning groove communicates with the outlet, and the width of the positioning groove gradually decreases from the opening towards the bottom of the groove in a rope-fixing direction; wherein at least one threading channel defines an inlet direction between the inlet and the positioning groove, and the rope-fixing direction and the inlet direction form an angle between 100 degrees and 170 degrees. In summary, the shoes, cord buckle assembly, and single-piece adjustment buckle disclosed in the embodiments of the present invention can, through structural configuration (such as the relative positional relationship between the receiving groove and the positioning groove, and the groove width configuration of the positioning groove), enable the single-piece adjustment buckle to stably fix the cord without using any spring structure, thereby effectively reducing the difficulty of overall production.

Furthermore, the accompanying drawings of this invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated in advance. The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention. It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various elements or features, these elements or features should not be limited by these terms. These terms are primarily used to distinguish one element from another, or one feature from another. Furthermore, the term "or" as used herein may, as appropriate, include any combination of one or more of the related listed items. [Example 1] Please refer to Figures 1 to 7, which illustrate Embodiment 1 of the present invention. As shown in Figures 1 to 3, this embodiment discloses a shoe 1000, which includes a shoe body 300, a strap 200 passing through the shoe body 300, and a single-piece adjustment buckle 100 installed on the strap 200. The structure or style of the shoe body 300 can be adjusted and varied according to actual needs. The strap 200 has two adjustment sections 201 extending out of the shoe body 300, and the strap 200 can also be an elastic strap or a non-elastic strap as needed; the present invention does not impose any limitations on this. It should be further noted that the cord 200 and the single-piece adjustment buckle 100 in this embodiment can be collectively referred to as a cord buckle assembly M. Although it is described in conjunction with the shoe body 300, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the cord buckle assembly M can be used alone (e.g., for sale) or in conjunction with other components (e.g., for bags or clothing); or, the single-piece adjustment buckle 100 can also be used alone (e.g., for sale) or in conjunction with other components according to actual needs. In this embodiment, as shown in Figures 3 to 6, the single-piece adjustment buckle 100 is a one-piece structure integrally formed; that is, any adjustment buckle with multiple components is different from the single-piece adjustment buckle 100 referred to in this embodiment. In this embodiment, the single-piece adjustment buckle 100 has a first plate 1 and a second plate 2 located on opposite sides, two sidewalls 3 connected to the outer edges of the first plate 1 and the second plate 2, a partition wall 4 connected to the center of the first plate 1 and the center of the second plate 2, and an inlet end 5 and an outlet end 6 located at the two ends of the first plate 1, but the present invention is not limited thereto. Furthermore, the single-piece adjustment buckle 100 is mounted on the shoe body 300 with the first plate 1, and the rope insertion end 5 is adjacent to a wearing opening 301 of the shoe body 300 (as shown in Figure 1). The single-piece adjustment buckle 100 has two rope-threading channels 7 internally, and the two rope-threading channels 7 are located on opposite sides of the partition wall 4. In this embodiment, the two rope-threading channels 7 may be completely separated by the partition wall 4 and not connected to each other, but this is not a limitation. It should be noted that in this embodiment, the two rope-threading channels 7 are arranged in a mirror-symmetrical configuration with respect to the partition wall 4, and the two adjustment sections 201 of the rope 200 are respectively threaded into the two rope-threading channels 7. Therefore, for ease of explanation, the following description will focus on one of the rope-threading channels 7 and its corresponding adjustment section 201, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the construction of the two rope-threading channels 7 may also be slightly different. In this embodiment, the rope-threading channel 7 has a receiving groove 71 and a positioning groove 72 located at the rope-out end 6 and communicating with the receiving groove 71. The receiving groove 71 has a rope inlet 711 located at the rope inlet end 5 and a rope outlet 712 recessed in the first plate 1 and adjacent to the rope-out end 6. Preferably, the rope outlet 712 is larger than the rope inlet 711, while the rope inlet 711 is slightly larger than the rope diameter of the adjusting section 201. The rope-threading channel 7 defines a rope-entry direction D1 between the rope inlet 711 and the positioning groove 72 (or, the rope-entry direction D1 is approximately parallel to the inner surface of the first plate 1). The opening 721 of the positioning groove 72 is connected to the rope outlet 712, and the width of the positioning groove 72 gradually narrows from the opening 721 toward its bottom 722 in a rope-fixing direction D2. Furthermore, the rope diameter of the adjustment section 201 is smaller than the width of the positioning groove 72; or, preferably, the rope diameter of the adjustment section 201 is smaller than the opening 721 of the positioning groove 72. The fixing direction D2 and the entering direction D1 form an angle between 100 degrees and 170 degrees. σ, and the included angle σ is preferably between 135 degrees and 150 degrees. In other words, the included angle... σ can also be defined as being formed by the positioning groove 72 sandwiching the inner surface of the first plate 1. Furthermore, at least 80% of the area of the positioning groove 72 may be located within a projection space formed by the orthographic projection of the rope inlet 711 along the rope inlet direction D1, but the invention is not limited thereto. Furthermore, the portion of the rope outlet 6 where the positioning groove 72 is formed has a guide wall 61 arranged along the rope fixing direction D2, and the guide wall 61 is part of the inner wall of the receiving groove 71. In this embodiment, the guide wall 61 is U-shaped and includes a turning section 611 connected to the first plate 1, and two guide sections 612 spaced apart from each other and connected to the turning section 611. That is, the positioning groove 72 is formed approximately inside the guide wall 61, and the bottom 722 of the positioning groove 72 approximately corresponds to the turning section 611. More specifically, the positioning groove 72 has two positioning walls 723 arranged facing each other, and two inclined walls 724 respectively connected to the two positioning walls 723. The distance between the two positioning walls 723 is defined as the groove width, and the two inclined walls 724 are connected to the guide wall 61, and the distance between the two inclined walls 724 is not less than the groove width. As described above, each of the adjustment segments 201 of the cord 200 can pass through the receiving groove 71 from the inlet 711 of one of the cord passages 7 and exit the receiving groove 71 from the outlet 712 (guided by the guide wall 61) to be in an adjustable state (e.g., FIG. 6). More specifically, in this embodiment, after being inserted into the inlet 711, the adjustment segment 201 can be bent by abutting against the turning section 611 and pass through the outlet 712 along the two guide sections 612. Furthermore, as shown in Figures 6 and 7, when any of the adjustment segments 201 of the cord 200 is in the adjustable state, the adjustment segment 201 can move within the receiving groove 71 corresponding to the cord threading channel 7, and the adjustment segment 201 can also be pulled away from the shoe body 300 so that it can be inserted into the groove bottom 722 of the positioning groove 72 corresponding to the cord threading channel 7, and then be compressed and deformed to be fixed in the positioning groove 72. Accordingly, in this embodiment, the rope buckle assembly M can achieve stable fixation of the rope 200 without using any spring structure by means of the structural configuration of the single-unit adjustment buckle 100 (e.g., the relative positional relationship between the receiving groove 71 and the positioning groove 72, and the groove width configuration of the positioning groove 72), thereby effectively reducing the difficulty of overall production. [Example 2] Please refer to Figure 8, which illustrates Embodiment 2 of the present invention. Since this embodiment is similar to Embodiment 1 described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiment 1 are roughly explained as follows: In this embodiment, the number of the cord-threading channels 7 formed by the single-piece adjustment buckle 100 can be one; that is, the number of cord-threading channels 7 in the single-piece adjustment buckle 100 can be adjusted according to the actual ball without forming the partition wall (not shown in the figure). Accordingly, according to Embodiment 1 and Embodiment 2, the interior of the single-piece adjustment buckle 100 can form at least one cord-threading channel 7 according to actual needs. [Example 3] Please refer to Figures 9 to 14, which illustrate Embodiment 3 of the present invention. Since this embodiment is similar to Embodiments 1 and 2 described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiments 1 and 2 are roughly explained as follows: In this embodiment, the single-piece adjustment buckle 100 can be slightly modified in its construction for application to a bag body 400 (e.g., a backpack), and the strap 200 passes through the bag body 400 and has two adjustment sections 201 extending out of the bag body 400. The second plate 2 of the single-piece adjustment buckle 100 is disposed on the surface of the bag body 400, and the single-piece adjustment buckle 100 may further include a webbing loop 8 extending from the second plate 2, so that the bag body 400 can be fitted with the single-piece adjustment buckle 100 by passing a webbing 401 through the webbing loop 8. Furthermore, when any of the adjustment segments 201 of the cord 200 is in the adjustable state, the adjustment segment 201 can move within the receiving groove 71 corresponding to the cord threading channel 7, and the adjustment segment 201 can also be pulled toward the package 400 so that it is inserted into the groove bottom 722 of the positioning groove 72 corresponding to the cord threading channel 7, and then deformed by pressure to be fixed in the positioning groove 72. [Example 4] Please refer to Figures 15 to 17, which illustrate Embodiment 4 of the present invention. Since this embodiment is similar to Embodiments 1 and 2 described above, the similarities between the above embodiments will not be repeated. The differences between this embodiment and Embodiments 1 and 2 are roughly explained as follows: In this embodiment, the single-piece adjustment buckle 100 can reduce its overall thickness, and the single-piece adjustment buckle 100 has a larger rope inlet 711 and rope outlet 712, so that the volume of the first plate 1 and the second plate 2 is significantly reduced. Furthermore, the single-piece adjustment buckle 100 may further include a fixing hook 9 extending from the rope inlet end 5, and the opening of the fixing hook 9 faces the first plate 1, but is not limited thereto. [Technical Effects of the Embodiments of the Invention] In summary, the shoes, cord buckle assembly, and single-piece adjustment buckle disclosed in the embodiments of the present invention can, through structural configuration (such as the relative positional relationship between the receiving groove and the positioning groove, and the groove width configuration of the positioning groove), enable the single-piece adjustment buckle to stably fix the cord without using any spring structure, thereby effectively reducing the difficulty of overall production. The above-disclosed content is only a preferred and feasible embodiment of the present invention and is not intended to limit the patent scope of the present invention.
