Description

Technical Field

[0001] This utility model relates to the technical field of shoelace tightening devices, and more specifically to a shoelace tightening device for sports shoes. Background Technology

[0002] The lacing tensioner for athletic shoes is a mechanical device used to adjust the tightness of shoelaces. It is usually made of plastic and contains gears or springs. The lacing tensioner helps users easily adjust the tightness of shoelaces through its mechanical structure, improving the comfort and functionality of athletic shoes.

[0003] The existing shoelace tightening device, as shown in application number: CN202420120219.4, is too large in its overall structure and cannot be adapted to sports shoes. Although it can tighten or loosen shoelaces in actual use, it is too troublesome to install and has poor practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a shoelace tightening device for sports shoes in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model proposes a shoelace tightening device for sports shoes, including an upper, a tongue, shoelace holes provided on the upper, a first shoelace and a second shoelace passing through the shoelace holes, and a tightening structure provided on the top of the tongue and located on the inside of the upper. The tensioning structure includes fixed hooks on both sides, a rotating rod on top, an unlocking rod next to the rotating rod for unlocking, a first rope inlet hole and a second rope inlet hole on the front side of the tensioning mechanism, a pin at the bottom inside the tensioning structure, and an unlocking spring inside the tensioning device and connected to the pin. The rotating rod is provided with a first winding point and a second winding point from top to bottom for winding the first shoelace and the second shoelace respectively. A first spring is arranged around the first winding point, and a first protrusion for locking is fixed at the bottom of the rotating rod. The unlocking rod is surrounded by a second spring, and a second protrusion for pushing the pin is fixed at the bottom of the unlocking rod; The pin has a fixing hole for locking the shoelace near the first protrusion, and an unlocking hole for unlocking the shoelace near the second protrusion.

[0006] As a preferred embodiment of this invention, the fixing hook is fixedly connected through the shoelace hole on the last side of the shoe upper.

[0007] As a preferred embodiment of this invention, the rotating rod can be rotated and pressed.

[0008] As a preferred embodiment of this utility model, the unlocking hole is an oblique groove, and the fixing hole has a slot inside.

[0009] The beneficial effects of this utility model are as follows: This invention utilizes the mechanical linkage of a rotating rod, an unlocking rod, and a pin to allow for easy adjustment of the shoelace tension without the need for manual tying, enabling quick adjustments during exercise. The structure of the pin and spring locks the shoelace in place, ensuring it won't come loose during activity and providing stable support. The slot design within the fixing hole further enhances the locking effect, reducing the risk of accidental loosening and improving safety. Attached Figure Description

[0012] like Figures 1 to 3 As shown, this utility model proposes: a shoelace elastic device for sports shoes, including an upper 2, a tongue 4, shoelace holes 3 provided on the upper 2, a first shoelace 5 and a second shoelace 6 passing through the shoelace holes 3, and an elastic structure 1 provided on the top of the tongue 4 and located on the inside of the upper 2; The tensioning structure 1 includes fixed hooks 13 on both sides, a rotating rod 11 on the top, an unlocking rod 12 next to the rotating rod 11 for unlocking, a first rope inlet hole 14 and a second rope inlet hole 15 on the front side of the tensioning mechanism, a pin 16 at the bottom inside the tensioning structure 1, and an unlocking spring inside the tensioning device and connected to the pin 16. The rotating rod 11 is provided with a first winding point 113 and a second winding point 114 from top to bottom for winding the first shoelace 5 and the second shoelace 6 respectively. A first spring 111 is arranged around the first winding point 113, and a first protrusion 112 for locking is fixed at the bottom of the rotating rod 11. The unlocking rod 12 is surrounded by a second spring 121, and a second protrusion 122 for pushing the pin 16 is fixedly installed at the bottom of the unlocking rod 12. The pin 16 has a fixing hole 163 for locking the shoelace near the first protrusion, and an unlocking hole 162 for unlocking the shoelace near the second protrusion.

[0013] The rotating rod 11 can be rotated and pressed.

[0014] The unlocking hole 162 is an inclined groove, and the fixing hole 163 has a slot inside.

[0015] The working principle of this utility model is as follows: The shoelaces pass through the shoelace eyelet 3 and enter the first and second rope inlet holes 15 of the tensioning structure 1, respectively, and are wound around the first and second winding points 114 of the rotating rod 11. Rotating the rotating rod 11 tightens the shoelaces. Pressing the rotating rod 11 causes the first protrusion 112 of the rotating rod 11 to insert into the fixing hole 163 of the pin 16. The groove of the fixing hole 163 prevents loosening, thus completing the locking. Pressing the unlocking rod 12 causes the second protrusion 122 to push the pin 16, causing the fixing hole 163 to separate from the first protrusion 112. The unlocking hole 162 (slanted groove) of the pin 16 guides the pin 16 to move, releasing the shoelaces. The second spring 121 resets the unlocking rod 12, and the first spring 111 resets the rotating rod 11, thus completing the unlocking. This device, through the cooperation of the rotating rod 11 and the unlocking rod 12, utilizes the restoring force provided by the spring to achieve rapid locking and unlocking of the shoelaces. It is easy to operate and has a compact structure. Example 2

[0016] The difference between this embodiment and embodiment 1 is that this embodiment adds a design for fixing hook 13 to be fixedly connected through the shoelace hole 3 on the last side of the upper 2; The fixing hooks 13 are installed on both sides of the elastic structure 1 and are fixedly connected through the shoelace hole 3 on the last side of the upper 2. This design uses the shoelace hole 3 on the last side of the upper 2 as a fixing point to embed the fixing hooks 13, thereby providing stable support for the elastic structure 1. The fixing hooks 13 are embedded in the shoelace hole 3 on the last side of the upper 2, and the structural strength of the shoelace hole 3 provides stable support for the elastic device, preventing the elastic structure 1 from shifting or loosening during use. By utilizing the existing shoelace holes 3 on the upper 2, the fixing hook 13 does not require an additional installation structure, making the overall design simpler and more compact, saving space; the fixing hook 13 is directly embedded in the shoelace holes 3, eliminating the need for complicated installation steps, simplifying the production process and reducing manufacturing costs; the shoelace holes 3 on the back side of the upper 2 are usually designed to be more robust and can withstand greater tension, so the connection of the fixing hook 13 is more secure, extending the service life of the tightening device.
