[0002] In daily production and life, there are many ways to fix wire or rope structures. The traditional fixing method is generally to manually tie the two ends of the wire or rope to fix it.

[0003] A relatively innovative method for tightening cords or ropes is to use a knob to achieve lace-free fastening. This effectively simplifies lacing and is particularly suitable for children and the elderly, and can be applied to shoelaces, clothing buttons, and other fields. During use, button products generally press an external rotating wheel to connect it with an internal clamping wheel. The user then rotates the external rotating wheel to drive the internal clamping wheel, thereby winding and tightening the cord. To loosen the cord, the external rotating wheel is pulled upward, and the user then pulls the cord to loosen it. Technical issues

Beneficial effects

[0023] The beneficial effects of the present invention are:

[0025] The utility model aims to provide a multifunctional button for achieving a fixed line without tying. Its function is to replace the traditional manual lacing method with a rotating anti-reverse knob. At the same time, by improving the anti-reverse knob structure, a bearing column extending downward in the axial direction is designed at its bottom as a bearing structure, and three limiting support bars are arranged in the radial direction on the outer wall of the bearing column.

Compared with the traditional spring locking method, the service life is longer. During the tightening process, the user rotates the direction knob to rotate the sub-teeth along the sliding direction of the main teeth.

The utility model provides two connecting grooves extending in the radial direction around the bottom through hole of the supporting column. At the same time, two inserts are provided on the outer wall of the socket on the upper part of the card wheel. When the anti-reverse knob is pressed downward, the inserts are inserted into the connecting grooves, so that the anti-reverse knob and the card wheel are radially limited and fixed. At the same time, in the actual production process, by providing an insert column extending upward in the axial direction at the top of the card wheel, the insert column is inserted into the slot provided in the middle of the supporting column of the anti-reverse knob to realize the mutual connection between the anti-reverse knob and the card wheel, so as to facilitate the overall transportation and transfer of materials, and the middle part of the insert column has an outward-opening external tension by providing a through slot, and the insert column and the slot can be connected and fixed by this external tension.

The sub-teeth on the limiting head cooperate with the female teeth on the clamping seat to realize the locking of the anti-reverse knob during the process of driving the clamping wheel to rotate to tighten the line, thereby preventing it from rotating in the opposite direction. Compared with the traditional spring locking method, the service life is longer. During the tightening process, the user rotates the direction knob to rotate the sub-teeth along the sliding direction of the main teeth. When the rotation is completed and the external force disappears, the internal stress of the limit bar causes the sub-teeth to embed into the main teeth to achieve locking. In addition, to ensure rotational stability, the utility model further provides a limit ring at the bottom of the support ring of the holder. The inner wall surface of the limit ring is an inclined annular surface. The bottom of the bearing seat is provided with a matching ring. The lower part of the matching ring is an inclined annular surface. When the anti-reverse knob is inserted into the holder, the matching ring and the inclined annular surface are mutually abutted. Through the above inclined surface matching structure, the anti-reverse knob does not block the rotation during rotation while playing a guiding and limiting role, effectively ensuring rotational stability. In addition, the anti-reverse knob needs to cooperate with the card wheel inside the card seat after being pressed, so as to drive the card seat to rotate and realize the function of winding and tightening the wire body. The utility model provides two connecting grooves extending in the radial direction around the bottom through hole of the supporting column. At the same time, two inserts are provided on the outer wall of the socket on the upper part of the card wheel. When the anti-reverse knob is pressed downward, the inserts are inserted into the connecting grooves, so that the anti-reverse knob and the card wheel are radially limited and fixed. At the same time, in the actual production process, by providing an insert column extending upward in the axial direction at the top of the card wheel, the insert column is inserted into the slot provided in the middle of the supporting column of the anti-reverse knob to realize the mutual connection between the anti-reverse knob and the card wheel, so as to facilitate the overall transportation and transfer of materials, and the middle part of the insert column has an outward-opening external tension by providing a through slot, and the insert column and the slot can be connected and fixed by this external tension.
