DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0024] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only relative positions on the specified view, rather than absolute positions.
[0025] In addition, in the present utility model, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0026] Please refer to Figures 1 to 11 , the cord buckle for easily adjusting the tightness of the present utility model is used to adjust the tightness of shoelaces and includes a female buckle 100, a male buckle 200, and a tension spring 300. The male buckle 200 is nested on the female buckle 100. One end of the tension spring 300 is connected to the female buckle 100, and the other end of the tension spring 300 is connected to the male buckle 200. The tension spring 300 tightens the male buckle 200 and the female buckle 100.
[0027] A first cord passing hole 1 is provided on the female buckle 100, and a second cord passing hole 5 is provided on the male buckle 200. A cord 400 passes through the second cord passing hole 5 and exits from the first cord passing hole 1. The cord 400 is clamped between the male buckle 200 and the female buckle 100.
[0028] A rack 8 is provided on the outer side of the male buckle 200, and a pressing inclined surface 111 is provided on the inner side wall of the female buckle 100. The cord 400 is clamped between the rack 8 and the pressing inclined surface 111. Due to the pulling force of the tension spring 300, the closer the rack 8 is to the pressing inclined surface 111, the greater the clamping force on the cord 400, and the tighter the cord 400 is fixed. Pulling the tension spring 300 apart can appropriately loosen the cord 400, and the cord 400 can be pulled and adjusted. It can be directly fixed on the shoelace to freely adjust the tightness of the shoelace, which is convenient to use and beneficial to improving the user experience.
[0029] The female buckle 100 is provided with an embedding groove 130, and the male buckle 200 is nested in the embedding groove 130.
[0030] To facilitate observing the internal structure of the female buckle 100, the female buckle 100 is cut in half from the middle to form a lower part 110 of the female buckle and an upper part 120 of the female buckle. The lower part 110 of the female buckle and the upper part 120 of the female buckle are integrally formed by connecting arms 140 on both sides. The embedding groove 130 is located between the lower part 110 of the female buckle and the upper part 120 of the female buckle. The first cord passing hole 1 is located in the embedding groove 130. The pressing inclined surface 111 is located on the inner side of the connecting arm 140.
[0031] To facilitate observing the internal structure of the male buckle 200, the male buckle 200 is cut in half from the middle to form a lower part 210 of the male buckle and an upper part 220 of the male buckle. The lower part 210 of the male buckle and the upper part 220 of the male buckle are integrally formed.
[0032] A first spring fixing end 4 is provided on the female buckle 100, and a second spring fixing end 7 is provided on the male buckle 200. One end of the spring 300 is fixed to the first spring fixing end 4, and the other end of the spring 300 is fixed to the second spring fixing end 7.
[0033] A spring hole 9 is provided on the male buckle 200, and the spring 300 passes through the spring hole 9. The spring 300 can expand and contract within the spring hole 9.
[0034] A catch 2 is provided on the inner side of the female buckle 100, and a card slot 6 is provided on the male buckle 200. The catch 2 extends into the card slot 6, which is beneficial to controlling the sliding range of the male buckle 200 on the female buckle 100 and can also prevent the male buckle 200 from detaching from the female buckle 100.
[0035] A first sliding groove 3 is provided on the female buckle 100, and a first slider structure matching the first sliding groove 3 is provided on the male buckle 200. The first slider structure is slidably connected to the first sliding groove 3, which is beneficial to the smooth sliding of the male and female buckles.
[0036] A second sliding groove 10 is provided on the male buckle 200, and a second slider structure matching the second sliding groove 10 is provided on the female buckle 100. The second slider structure is slidably connected to the second sliding groove 10, which is beneficial to the smooth sliding of the male and female buckles.
[0037] For the rope buckle with adjustable tightness of the present utility model, the male buckle 200 and the female buckle 100 achieve sliding fit through the sliding groove and the card slot. Both ends of the spring 300 are respectively fixed on the male and female buckles. The male and female buckles can be firmly combined through the spring 300, and the tightness degree depends on the pulling force of the spring 300. The greater the pulling force, the tighter the male and female buckles are combined. When in use, both shoelaces pass through the male and female buckles. The inner side of the shoelace is closely attached to the rack 8 of the male buckle 200, and the outer side of the shoelace is closely attached to the inner wall of the female buckle 100. Due to the inclination of the inner wall, the more the male buckle 200 enters the female buckle, the tighter the pressing inclined surface 111 and the rack 8 will clamp the shoelace. When the pulling force of the spring 300 is large enough, the shoelace will be fixed on the male and female buckles and cannot move. Only when an external force overcomes the pulling force of the spring 300 and separates the male buckle 200 from the female buckle 100 by a certain distance, the rack 8 of the male buckle 200 and the inner wall of the female buckle 100 will not clamp the shoelace, and at this time the shoelace can slide.
[0038] Compared with the prior art, the rope buckle with adjustable tightness of the present utility model has a simple structure and a delicate appearance. It can be directly fixed on the shoelace to freely adjust the tightness of the shoelace, which is very convenient to use and is beneficial to improving the user experience and convenience.
[0039] The above description is only a preferred embodiment of the present utility model, and does not limit the patent scope of the present utility model accordingly. Any modifications, equivalent replacements, and improvements made within the concept of the present utility model shall be included in the patent protection scope of the present utility model.
