AI Technical Summary
In the prior art, devices for adjusting tightness usually adopt a knob with exposed wires, resulting in messy elastic lines, which are prone to knots or tied to other objects.
A device for adjusting the tightness of the hidden knob is designed. By setting wearable fixing parts on both sides of the elastic band, a cavity and a draw rope are set inside, and the two ends of the draw rope are wrapped around the knob, and the tightness of the draw rope is adjusted through the knob, thereby hiding the draw rope and avoiding exposure.
While adjusting the tightness through the knob, it hides the drawstring, avoiding the mess and knotting problems caused by exposure, and improving the aesthetics and convenience of use.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tightness adjustment, and in particular relates to a device for adjusting tightness with a hidden knob. Background Art
[0002] Among the many devices and products that require adjustment of tightness, such as adjustable watch straps, backpack straps, waist-cinching parts of clothing, etc., the adjustment methods currently available on the market are all knob adjustment methods with exposed wires, which make the elastic wire harness messy and unsightly, and are also easily tangled or tied to other objects. Utility Model Content
[0003] In order to solve the problem that the traditional adjustment methods mentioned above are generally knob adjustment methods with exposed wires, which makes the wire bundles of the elastic wires messy and easy to get tangled, the utility model provides a device for adjusting the tightness with a hidden knob.
[0004] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a device for adjusting tightness with a hidden knob, comprising an elastic band and a wearing and fixing part, wherein the wearing and fixing part is provided in two groups and is located at both side ends of the elastic band, the wearing and fixing part and the elastic band are both provided with cavities and are communicated with each other, a drawstring is passed through the cavity, a knob is rotatably provided on the wearing and fixing part, and the drawstring is placed in the cavity and is well hidden.
[0005] As a preferred technical solution of the utility model, the two ends of the pull rope are respectively wound around two sets of knobs, and the pull rope can be wound through the two sets of knobs to adjust the tightness.
[0006] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects: by hiding the drawstring in the cavity and covering the elastic band on the outside, it is convenient to adjust the drawstring by turning the knob to adjust the elastic band, and at the same time the hidden setting prevents the drawstring from being exposed on the outside and appearing messy, loose and easy to get tangled.

[0009] Among them, 1. elastic band, 2. wearing and fixing part, 3. cavity, 4. drawstring, 5. knob. DETAILED DESCRIPTION
[0010] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0011] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.
[0012] like Figure 1-2 As shown, the utility model provides a hidden knob device for adjusting tightness, comprising an elastic band 1 and a wearing and fixing part 2, wherein the wearing and fixing part 2 is provided with two groups and is located at both side ends of the elastic band 1, wherein the wearing and fixing part 2 and the elastic band 1 are both provided with cavities 3 inside and are communicated with each other, wherein a drawstring 4 is passed through the cavity 3, and a knob 5 is rotatably provided on the wearing and fixing part 2, wherein both ends of the drawstring 4 are respectively wound around two groups of knobs 5, and the drawstring 4 is placed in the cavity 3 and is well hidden, and the drawstring 4 can be wound around the two groups of knobs 5 to adjust the tightness.
[0013] When in use, the wearing fixing part 2 is fixed on the wearable article, and then the tightness of the drawstring 4 is controlled by turning the knob 5 .
[0014] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
