Description

Technical Field

[0001] The utility model belongs to a rotating buckle, in particular to an adjustable rotating buckle. Background Art

[0002] Currently, using ropes to tighten shoes, helmets, shoulder pads, etc. is a common method. When tightening the ropes, traditionally, it requires two hands to tie the two ends of the ropes, which takes a certain amount of time. In addition, the location of the ropes is not convenient for two hands to operate for helmets and shoulder pads.

[0003] In order to facilitate shoe lacing, some existing shoes are also equipped with shoe lace tightening and fixing devices, which can tighten or loosen the shoe laces to facilitate putting on and taking off shoes. However, when the shoe laces are sometimes tied too tight, the knob needs to be manually pulled up to adjust again, and the shoe lace tightening and fixing device itself cannot be used to adjust the shoe laces, which is inconvenient.

[0034] like Figures 1 to 7As shown, an adjustable rotary buckle comprises a base 1 and a knob 2, the knob 2 being buckled onto the base 1; an inner cavity 21 is formed between the knob 2 and the base 1; a winding sleeve 3 is provided in the inner cavity; the base 1 comprises a support portion 11 and a flat portion 12; the winding sleeve 3 passes through the support portion 11 and is clamped to the flat portion 12; the support portion 11 also passes through an inner spiral tooth 4 and a rotating member 5; the winding sleeve 3 and the inner spiral tooth 4 are elastically connected by a spring 6; a notch 111 is provided in the middle of the support portion 11, so that the support portion 11 has a certain elasticity, and a protrusion 112 is provided on the outside of the support portion 11; the protrusion 112 abuts against the inner side of the rotating member 5; the support portion 11 is located on both sides of the notch 111 A boss 113 is provided on the side; when the rotary buckle is installed on the shoe, the elasticity of the support part 11 makes it easy to adjust when the cutout groove 111 cooperates with the matching accessory, and bosses 113 are provided on both sides of the support part 11 for easy clamping, thereby improving the practicality of the product; the rotation of the inner rotating tooth 4 can make the rotating part 5 rotate unidirectionally relative to the base 1 through the clutch ratchet 7, and a rope is placed in the winding sleeve 3, so that the winding sleeve 3 can tighten the rope synchronously; when the knob 2 is pulled up to separate the clutch ratchet 7 between the inner rotating tooth 4 and the rotating part 5, the rope on the winding sleeve 3 can be loosened outward, and the rotating part 5 is located on the inner side of the knob 2; an outer rotating tooth 8 is provided in the rotating part 5; the outer rotating tooth 8 can be rotatably inserted into the rotating part 5; the outer rotating tooth 8 includes a snap ring 81; a plurality of elastic arms 811 are distributed along the circumference of the outer side of the snap ring 81; the elastic arm 811 is provided with an abutment 812; the abutment 812 includes a slot 813; the rotating member 5 is provided with a plurality of clamping columns 51, and the clamping slot 813 can be movably clamped in the clamping column 51, and the knob 2 is provided with a gear 22 on the peripheral side of the outer rotating tooth 8, and a spring 6 is added between the winding sleeve 3 and the inner rotating tooth 4. When the rope is tightened too much, the spring 6 drives the rotating member 5 and the outer rotating tooth 8 to rotate in the opposite direction through its resilience to loosen the rope outward to a normal state, thereby improving the practicality of the product. Furthermore, the elastic arm 811 on the outer rotating tooth 8 will also be pushed due to the abutment against the gear 22 when the spring 6 rebounds, and the inner diameter of the slot 813 It is larger than the outer diameter of the post 51, so the slot 813 is also pushed to the side of the post 51, so the stroke for the rope to be loosened outward is the total stroke of the movable stroke of the elastic arm 811 and the movable stroke of the slot 813 in the post 51; the abutment 812 is located on one side of the gear 22; the abutment 812 can drive the rotating member 5 to rotate, and further, when the abutment 812 rotates counterclockwise relative to the base 1, the abutment 812 abuts the gear 22; when the abutment 812 rotates clockwise relative to the base 1, the abutment 812 can drive the rotating member 5 to rotate; one side of the knob 2 abuts against a rotary cover 9, and a plurality of hooks 91 are provided in the rotary cover 9, and the hooks 91 engage the rotating member 5 to prevent the rotary cover 9 from falling off the knob 2;The inner circumference of the rotary cover 9 is provided with a plurality of limit members 92, which abut against the circumference of the knob 2 to ensure that the rotary cover 9 fits the knob 2 to prevent it from slipping; the rope is loosened by pulling up the knob 2 to prevent the rope from loosening due to accidental touch; since the inner rotating teeth 4 and the clutch ratchet 6 of the rotating member 5 are arranged up and down, the rotating member 5 will move up and down during the rotation process. In order to prevent the rotating member 5 from falling off, the upper and lower limits of the rotating member 5 are located between the rotary cover 9 and the inner rotating teeth 4, even if the rotating member 5 is relative to the inner rotating teeth 4 due to the activity of the clutch ratchet 7, Even small movements of the rotating gear 4 do not completely separate. When the knob 2 stops turning, the outer rotating gear 8 abuts against the gear 22 of the knob 2, ensuring the tightening of the strap. A protective sleeve 10 is fixedly attached to the outside of the knob 2. The winding sleeve 3 includes two rope holes 31. The knob 2 is provided with a rope threading slot 23 corresponding to the rope holes 31, and the length of the strap can be adjusted by rotating the knob 2. The outer side of the rotating cover 9 is provided with multiple protrusions 93 along its circumference. The outer side of the protective sleeve 10 is provided with a curved surface 101, which can be in close contact with the shoe surface.
