Description

Technical Field

[0001] The utility model relates to the technical field of shoelace adjustment, in particular to a shoelace tightness adjuster. Background Art

[0002] Shoelace tightness adjustment is an important step when wearing shoes, which directly affects the comfort of the feet and the fit of the shoes. Adjusting the shoelace tightness is usually very simple. Just untie the shoelace bow, and then, as needed, pull the two ends of the shoelace appropriately tight or loose, and tie a knot again. To ensure comfort, it is recommended to stand up when adjusting the shoelaces while wearing shoes, so that you can more accurately feel the need for the tightness of the shoes during different activities. The correct tightness should neither be too tight so as to press the instep nor too loose so that the shoes are likely to fall off. In addition, for people who often do strenuous exercise, they may need tighter shoelaces to prevent their feet from slipping inside the shoes. For daily wear, a moderate tightness is more appropriate to ensure a comfortable wearing experience throughout the day.

[0003] Although the method of tying and binding the shoelaces to complete the fixation of the shoelaces is convenient and can also take into account the function of tightness adjustment at the same time, the tying method connects the shoelaces, so that the shoelaces are mainly fixed and maintained by the friction between the shoelaces. However, such a method is not durable. Therefore, it is also necessary to complete the tightness adjustment and fixation of the shoelaces without tying the shoelaces.

[0004] Therefore, a shoelace tightness adjuster is proposed to solve or alleviate the above problems. Content of the Utility Model

A clamping groove for the shoelace to pass through is formed between adjacent clamping columns, and the outer adjustment cylinder displaces to adjust the distance between adjacent clamping columns.

[0008] Preferably, the cross-sectional areas of the plurality of clamping columns are gradually increased from the end connected to the outer connection cylinder, and the length of the outer adjustment cylinder is the same as the length of the outer connection cylinder.

[0026] A shoelace tension adjuster,

[0027] such as Figures 1 to 3As shown in the figure, it includes an inner connecting disc 1, a connecting rod 3 fixedly connected to the inner connecting disc 1 and capable of passing through the shoelace holes, an outer connecting cylinder 5 detachably connected to the connecting rod 3 and used to cooperate with the inner connecting disc 1 to clamp the shoe upper, a number of clamping columns 7 fixedly connected to the outer end face of the outer connecting cylinder 5 and expanding outwards, and an outer adjusting cylinder 9 sleeved on the outer ring of the outer connecting cylinder 5 and capable of displacing along its length direction. A clamping groove 8 for the shoelace to pass through is formed between adjacent clamping columns 7. The outer adjusting cylinder 9 displaces to adjust the distance between adjacent clamping columns 7. The cross-sectional areas of the number of clamping columns 7 are gradually increasing from the end connected to the outer connecting cylinder 5. The length of the outer adjusting cylinder 9 is the same as the length of the outer connecting cylinder 5.

[0028] A first-stage external connection thread is provided on the outer ring of the connecting rod 3, and a first-stage internal connection thread 6 is provided on the inner ring of the outer connecting cylinder 5. The connecting rod 3 and the outer connecting cylinder 5 are detachably connected through the first-stage external connection thread and the first-stage internal connection thread 6. A second-stage external connection thread is provided on the outer ring of the outer connecting cylinder 5, and a second-stage internal connection thread is provided on the inner ring of the outer adjusting cylinder 9. The outer adjusting cylinder 9 and the outer connecting cylinder 5 are detachably connected through the second-stage external connection thread and the second-stage internal connection thread. A bottom soft pad 2 is fixedly connected to the side of the inner connecting disc 1 away from the connecting rod 3, and an annular soft pad 4 located on the outer ring of the connecting rod 3 is fixedly connected to the side of the inner connecting disc 1 facing the connecting rod 3.

[0029] When the present utility model is in use, the inner connecting disc 1 is placed inside the shoe, and then the connecting rod 3 is passed through the shoelace hole. Then, the outer connecting cylinder 5 is connected to the connecting rod 3 through the first-stage external connection thread and the first-stage internal connection thread 6. At this time, the outer connecting cylinder 5 and the inner connecting disc 1 clamp the shoe upper. The bottom soft pad 2 on the inner connecting disc 1 can make the bottom soft pad 2 contact the instep of the user when the user wears the shoes, avoiding the inner connecting disc 1 from touching the instep of the user and causing discomfort to the user. The setting of the annular soft pad 4 is to prevent the inner connecting disc 1 from clamping the shoe upper when the inner connecting disc 1 and the outer connecting cylinder 5 clamp the shoe upper. At this time, the user passes the shoelace through the clamping groove 8 multiple times according to his own needs, so that the available length of the shoelace changes. Then, the second-stage external connection thread and the second-stage internal connection thread are used to guide the outer adjusting cylinder 9 to displace in the length direction of the outer connecting cylinder 5, and the outer adjusting cylinder 9 displaces to adjust the distance between adjacent clamping columns 7, so that the shoelace can be clamped in the clamping groove 8. In this way, the user no longer needs to tie the shoelace and can adjust the tightness of the shoelace according to his own needs.

[0030] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
