[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment 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.

[0024] Please refer to Figure 1 and Figure 2 An embodiment of the utility model provides an adjustment structure of a head-mounted braided strap that can retract and adjust the head circumference, comprising an elastic braided strap 1, a pull cord 2 and a knob-type pull cord retracting device 3, wherein the knob-type pull cord retracting device 3 is rotatably mounted on one side of the elastic braided strap 1, the pull cord 2 is mounted in the knob-type pull cord retracting device 3, and the protruding portion of the pull cord 2 can extend out of the knob-type pull cord retracting device 3 and pass through the elastic braided strap 1 along the length direction of the elastic braided strap 1, and finally be fixed on the other side of the elastic braided strap 1.

[0025] The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1 and Figure 3 As shown, the knob-type wire drawing and releasing device 3 may include a chassis 31, a rotating disk 32 and a rotating disk stabilizing member 33. The chassis 31 may be fixedly connected to one side of the elastic braided belt 1 by glue. The rotating disk 32 is rotatably connected to the chassis 31, as shown in FIG. Figure 3 , Figure 4 and Figure 5As shown, as a preferred embodiment, the edge of the rotating disk 32 can be provided with at least two centrally symmetrical turntable buckles 321 (preferably four), and the outer wall of the chassis 31 is provided with a circular convex ring 312. The rotating disk 32 can be buckled on the convex ring 312 of the chassis 31 through the turntable buckles 321, so that the rotating disk 32 and the chassis 31 are rotatably connected.

[0027] The rotating disk 32 is provided with a rotating disk wire hanging member that can rotate with the rotating disk 32 inside the chassis 31. The pull wire passes through the wire hole 311 on the outer wall of the chassis 31 and extends into the interior of the chassis 31 to be hung on the rotating disk wire hanging member. As a preferred embodiment, Figure 4 and Figure 5 As shown, the turntable wire hanging member may include a wire hanging block 324 and a wire fixing screw 34 . The wire hanging block 324 is connected to the rotating disk 32 and can be inserted into the interior of the chassis 31 . The wire fixing screw 34 can lock the pull wire at the bottom of the wire hanging block 324 .

[0028] like Figure 3 As shown, the rotating disk stabilizer 33 is fixedly connected to the outside of the rotating disk 32. The rotating disk stabilizer 33 can be configured as a circular wheel structure, which is convenient for users to rotate.

[0029] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, the knob-type wire pulling and releasing device 3 can also include a rotating screw 35 and a nut 36. The head end (hexagonal head) of the rotating screw 35 is positioned and installed in the positioning screw groove 322 (hexagonal groove) on the top of the rotating disk 32. The rotating screw 35 can rotate along with the rotating disk 32. The threaded end of the rotating screw 35 passes through the center hole of the rotating disk 32 and is threadedly connected with the nut 36 in the nut positioning groove 313 (hexagonal groove) fixed inside the chassis 31.

[0030] Rotating the rotating disk stabilizer 33 can drive the rotating screw 35 to rotate. When the rotating screw 35 is tightened in one direction, the bottom of the rotating disk stabilizer 33 can be pressed against the chassis 31, so that the knob-type wire pulling and releasing device 3 is in a locked state. When the rotating screw 35 is rotated in the opposite direction, the pressing state between the bottom of the rotating disk stabilizer 33 and the chassis 31 is released.

[0031] Better, such as Figure 1 and Figure 3As shown, the knob-type cable retracting and releasing device 3 may further include an upper cover 37, which is mounted on the top of the rotating disk stabilizer 33 and covers the rotating screw 35. Specifically, at least two centrally symmetrical upper cover buckle positions 371 may be provided at the bottom of the upper cover 37, and at least two centrally symmetrical buckle grooves 323 may be provided on the rotating disk 32. The upper cover 37 is buckled with the buckle grooves 323 of the rotating disk 32 through the upper cover buckle positions 371, so that the upper cover 37 and the rotating disk 32 are snap-fitted.

[0032] In this embodiment, the pull wire 2 can be preferably configured as an elastic pull wire. The pull wire 2 can be configured into a U-shaped structure, and two sections of the U-shaped pull wire pass through the elastic braided belt 1, so that the structural strength of the pull wire 2 can be enhanced.

[0033] Matching the U-shaped structure of the cable 2, such as Figure 2 , Figure 4 and Figure 6 As shown, the outer wall of the chassis 31 can be provided with two wire holes 311. After the middle position of the pull wire 2 is hung on the rotating disk 32 through the turntable hanging piece 34, the wire ends at both ends thereof extend out from the two outer wall wire holes 311 respectively, and the wire ends at both ends of the pull wire 2 can be fixed to the other side of the elastic braiding belt 1 by glue.

[0034] Of course, according to actual needs, in other embodiments, the pull wire 2 can also adopt a single-section structure, one end of the pull wire 2 can be hung on the rotating disk 32 through a turntable hanging piece 34, and the other end of the pull wire 2 is fixed to the other side of the elastic braiding belt 1.

[0035] The working principle of the adjustment structure of this embodiment is as follows:

[0036] When the elastic braid 1 is in a loose state and needs to be adjusted, the user can turn the knob-type pull-wire retracting device 3 in one direction, and the pull wire 2 is pulled and reeled into the knob-type pull-wire retracting device 3, so that the elastic braid 1 can be contracted and tightened. When the user turns the knob-type pull-wire retracting device 3 in the opposite direction, the pull wire 2 is unwound, which has the effect of loosening the elastic braid 1. At this time, the elastic braid 1 can be reset due to its own elasticity.

[0037] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
