[0064] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application discloses a tightening mechanism 100 of an embodiment, which is used for adjusting the lacing (not shown in the figure) on the wearable article (not shown in the figure).

[0065] The tightening mechanism 100 comprises a base member 10 with a mounting flange 14 for fixing the tightening mechanism to the wearable article; the base member 10 has an inner side facing the wearable article and an outer side facing away from the wearable article. Among them, the inner side of the base member 10 is provided with a lacing guide part 16, the lacing guide part 16 comprises one or more guide grooves 101 for hiding the lacing under the mounting flange 14; the base member further comprises a receiving cavity 103, the one or more guide grooves 101 and the receiving cavity 103 are in communication.

[0066] The outer side of the base member 10 is provided with a boss 12 with an inner cavity, the mounting flange 14 is arranged on the periphery of the boss 12, and the boss 12 is protruded outward from the mounting flange 14. The lace guide part 16 is protruded inward from the base member 10 and has a cavity, and the cavity is communicated with the inner cavity of the boss to form the containing cavity 103. The boss 12 is arranged in the middle region of the outer side of the base member 10, the lace guide part 16 is arranged in the central region of the inner side of the base member 10, and the lace guide part 16 is provided with two guide grooves 101, which are communicated with the containing cavity 103 after penetrating through the lace guide part 16. In this embodiment, the lace guide part is configured as a hollow protrusion 16 which has a cavity and is protruded inward from the base member. The guide grooves 101 are oppositely arranged, and the number of the guide grooves 101 is not limited to two, and can be other numbers. The plurality of guide grooves 101 can be arranged at intervals along the side wall of the lace guide part.

[0067] Compared with the conventional scheme, when the tightening mechanism of the utility model is applied to the wearable article, the lace can reach the outer side of the base member 10 through the guide groove 101 and be contained in the containing cavity 103 or connected with other parts of the tightening mechanism, so that the lace can be hidden, thereby avoiding the influence of the lace on the surface of the wearable article and affecting the appearance. Especially when the tightening mechanism is installed at the heel position of the shoe article, the lace segment which runs along the ankle to the heel position can be hidden to meet the aesthetic needs of some users.

[0068] In addition, the base member 10 of the tightening mechanism of the utility model is integrally formed with the outwardly protruding boss 12, the mounting flange 14 and the inwardly protruding lace guide part 16 and the containing cavity 103, so that the base member 10 has multiple functions including being fixed to the wearable article, being connected with other parts of the tightening mechanism and hiding the lace, thereby reducing the number of parts and simplifying the installation process.

[0069] In this embodiment, the mounting flange 14 is annular and extends radially along the boss 12, and the guide grooves 101 extend obliquely downward along the extension direction of the mounting flange. In this embodiment, the mounting flange 14 can be fixed to the wearable article by sewing.

[0070] Specifically, in combination with the drawings, the lace guide part 16 and the inner side of the mounting flange 14 jointly enclose the placement groove 102, and the placement groove 102 is used to contain the sewing jig, so that the sewing between the mounting flange 14 and the wearable article can be more conveniently realized. Specifically, when the mounting flange 14 is sewn to the wearable article, the end of the sewing jig is contained on the placement groove 102, and the sewing needle of the sewing jig is arranged above the mounting flange 14 and is oppositely arranged with the sewing jig.

[0071] In combination with the drawings, Figure 2In this embodiment, the projection of the strap guide 16 onto the central axis of the base member 10 ( Figure 2 The outer contour line 16) shown in the top view is entirely located inside the outer contour line of the boss 12. Further reference... Figure 2 In this embodiment, a sewing outline 17 is set in the area of ​​the mounting flange 14 near the outer edge of the boss 12. When installing the base component, the needle moves along the trajectory of the sewing outline 17. Since the outer outline of the tie guide 16 (shown by the dotted line) is located inside the sewing outline 17, the tie guide 16 located inside the base component will not obstruct the sewing process when the base component and wearable items are fixed using a jig and sewing machine. This structural design allows the base component to be integrally molded without the need to design the tie guide 16 and the mounting flange 14 separately and then fix them together, thus simplifying the installation process of the base component.

[0072] Combined with appendix Figure 4 The mounting flange 14 has an arc-shaped cross-section to conform to the contour of the mounting area. The bottom cross-section of the tie guide 16 is also arc-shaped. In this embodiment, by making the bottom arc of the tie guide 16 gentler, the drop between it and the mounting flange 14 is reduced, providing sufficient space to accommodate the sewing jig, so that the needle will not contact the side wall of the tie guide during sewing, thereby ensuring the smooth sewing process of the base component.

[0073] Preferred, combined with appendix Figure 1 In this embodiment, the fastening mechanism 100 further includes a housing 20 disposed within the receiving cavity 103 and a spool 30 rotatably disposed within the housing 20 for winding the strap. The housing 20 has a threading hole 201 communicating with the guide groove 101, and the spool 30 communicates with the guide groove 101 through the threading hole 201. At this time, after the strap reaches the receiving cavity 103, which opens towards the outer side of the base member 10, through the guide groove 101, it can continue to pass through the threading hole 201 and connect with the spool 30.

[0074] Furthermore, in conjunction with the appendix Figure 1 In this embodiment, the inner wall of the receiving cavity 103 is provided with a snap-fit ​​portion 18, and the outer side of the housing 20 is provided with a snap-fit ​​mating portion 22 that snaps into the snap-fit ​​portion 18. This structural arrangement allows for a detachable connection between the housing 20 and the base component 10, facilitating replacement of the fastening mechanism 100 after damage. Specifically, in this embodiment, the snap-fit ​​portion 18 is a slot 18, and the snap-fit ​​mating portion 22 is a lug; more preferably, the slot 18 extends from the bottom of the receiving cavity 103 to the inner wall of the receiving cavity 103, such as... Figure 3 As shown.

[0075] Preferred, combined with appendix Figure 1In the embodiment, the tightening mechanism 100 further comprises a reverse stopping member 40 fixedly arranged on the shell 20 and a rotary cover 50 rotatably connected with the shell 20. When the rotary cover 50 rotates relative to the shell 20, the winding drum 30 is driven to rotate relative to the shell 20. Specifically, the shell 20 is provided with a connecting through hole 202, and the upper end of the winding drum 30 is connected with the rotary cover 50 in an operable manner after penetrating through the connecting through hole 202. When the rotary cover 50 rotates relative to the shell 20, the winding drum 30 is driven to rotate relative to the shell 20, so as to realize the winding and tightening of the belt.

[0076] It should be noted that the reverse stopping member 40 and the shell 20 and the rotary cover 50 are respectively provided with anti-rotation assemblies matched with each other, so that after the rotary cover 50 drives the winding drum 30 to rotate in the tightening direction, the winding drum 30 is prevented from rotating reversely, thereby preventing the belt from being loosened accidentally. In the embodiment, the reverse stopping member 40, the stop block 203 on the shell and the groove (not shown) on the rotary cover cooperatively form the anti-rotation assembly. However, the anti-rotation assembly is not limited to the structure shown in the drawings of the utility model, and other mechanical structures capable of realizing the anti-rotation function can be applicable, such as a pawl-ratchet assembly.

[0077] Preferably, referring to Figure 1 and Figure 2 In the embodiment, the outer edge of the boss 12 is further provided with at least two protective members 122 for protecting the shell, the rotary cover and other structures of the tightening mechanism from being damaged due to external impact.

[0078] The above-described tightening mechanism can be applied to various articles with a belt for adjusting the tightness, such as a backpack with a belt, a box with a belt and the like. Hereinafter, the tightening mechanism applied to a wearable article will be taken as an example for introduction.
