Description

Technical Field

[0001] The utility model relates to the technical field of rotary buttons, in particular to a rotary button capable of independently adjusting the tightness of cords in two directions. Background Art

[0002] Knob buckles adjust the tightness by controlling the retraction and extension of the straps. However, current knob buckles can generally only adjust the tightness in one direction. They are not very suitable for positions that need to be adjusted in two directions, such as VR glasses, head-mounted lights, and physiotherapy eye masks. These products are front-heavy and generally have two straps designed horizontally and vertically to make them more stable. However, if traditional knob buckles are used to adjust the tightness, two knob buckles need to be installed to adjust the horizontal and vertical straps. When adjusting the tightness, two knob buckles need to be adjusted, which is very inconvenient. Utility Model Content

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] See Figures 1 to 9As shown, the structure of the utility model is: a knob buckle that can independently adjust the tightness of the rope in two directions, including a base 2; a bracket 3, which is installed on the base 2; a first rotating wheel 4 and a second rotating wheel 8, which are rotatably arranged in the bracket 3, and the inner sides of the first rotating wheel 4 and the second rotating wheel 8 are provided with a first groove 401, and the first rotating wheel 4 and the second rotating wheel 8 are respectively provided with a first wire groove 402 and a second wire groove 801; the first wire rope 5 and the second wire rope 7 are respectively wound in the first wire groove 402 and the second wire groove 801, and pass through the base 2 from two directions respectively; a spline rod 10, which is inserted into the first rotating wheel 4 and the second rotating wheel 8, and the middle part of the spline rod 10 is provided with key teeth 1001 that respectively cooperate with the first grooves 401; the first damping member 6 and the second damping member 9, which are both fixedly arranged on the bracket 3, respectively used to provide damping effects to the first rotating wheel 4 and the second rotating wheel 8; a rotary cover 11, which is sleeved The first gear 10 is engaged with the first gear 10 on the second gear 10, and the second gear 10 is engaged with the first gear 10 on the second gear 10. When the first gear 10 is engaged with the first gear 10, the second gear 10 is engaged with the first gear 10 on the second gear 10. When the first gear 10 is engaged with the first gear 10, the second gear 10 is engaged with the first gear 10 and the second gear 10 is engaged with the first gear 10. When the first gear 10 is engaged with the first gear 10, the second gear 10 is engaged with the first gear 10

[0025] like Figure 6 As shown, a first clip 1002 is provided at the lower end of the spline rod 10, and a first slot 201 is provided on the base 2 to be engaged with the first clip 1002. Specifically, by pressing the rotary cover 11, the spline rod 10 is driven to move downward, and the first clip 1002 is buckled into the first slot 201, ensuring that the key teeth 1001 and the first groove 401 on the first rotating wheel 4 are always tightly engaged.

[0026] As shown Figure 8 、 Figure 9 As shown, a second buckle 1101 is provided on the inner side of the rotary cover 11, and a block 202 is provided on the edge of the base 2 to engage with the second buckle 1101. Specifically, when the rotary cover 11 is pulled up, the spline rod 10 is driven to move upward, the first buckle 1002 disengages from the first slot 201, and the second buckle 1101 engages the block 202 to prevent the rotary cover 11 from falling off, thereby ensuring that the key teeth 1001 and the first groove 401 on the second rotating wheel 8 are always tightly engaged.

[0027] like Figure 5 、 Figure 7 As shown, the first damping member 6 and the second damping member 9 both include a mounting ring 601 fixedly mounted on the bracket 3, an elastic arm 602 is provided on the mounting ring 601, and a boss 603 is provided at the end of the elastic arm 602, and the first rotating wheel 4 and the second rotating wheel 8 are both provided with a second groove 403 abutting against the boss 603. Specifically, when adjusting the tightness of the first rope 5, under the action of the elastic arm 602 on the second damping member 9, the boss 603 on the second damping member 9 is clamped into the second groove 403 on the second rotating wheel 8 to prevent the second rope 7 on the second rotating wheel 8 from loosening; when adjusting the tightness of the second rope 7, under the action of the elastic arm 602 on the first damping member 6, the boss 603 on the first damping member 6 is clamped into the second groove 403 on the first rotating wheel 4 to prevent the first rope 5 on the first rotating wheel 4 from loosening.

[0028] like Figure 8 As shown, a fixing seat 1 is provided at the bottom of the base 2, a third buckle 101 is provided on the fixing seat 1, and a second card slot 203 is provided on the base 2 to be engaged with the third buckle 101. Specifically, the fixing seat 1 is used to install the base 2.

[0029] During specific use, the rotary cover 11 is pressed to drive the spline rod 10 to move downward, and the key teeth 1001 engage with the first groove 401 on the first rotating wheel 4, and then the rotary cover 11 is rotated to drive the first rotating wheel 4 to rotate to tighten or loosen the first rope 5. At the same time, because the second damping member 9 has a damping effect on the second rotating wheel 8, the second rotating wheel 8 will not rotate, ensuring that the second rope 7 will not loosen; pull up the rotary cover 11 to drive the spline rod 10 to move upward, and the key teeth 1001 disengage from the first groove 401 on the first rotating wheel 4, and then engage with the first groove 401 on the second rotating wheel 8, and then rotate the rotary cover 11 to drive the second rotating wheel 8 to rotate to tighten or loosen the second rope 7. At the same time, under the damping action of the first damping member 6, the first rotating wheel 4 will not rotate, ensuring that the first rope 5 will not loosen, thereby realizing the adjustment of the tightness of the ropes in two different directions.

[0030] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
