Description

Technical Field

[0001] This utility model relates to the field of buckles, and more specifically, to a knot buckle that can adjust and fix ropes. Background Technology

[0002] With the increasing prevalence of buckles, knots for adjusting and fixing the relative length of ropes have emerged. CN216907048U discloses a self-locking rope buckle, including an inner rope buckle, an outer rope buckle, and a spring. The bottom of the inner rope buckle has a malleable expansion member and a first rope hole for threading rope. The outer rope buckle has a first groove inside, and an impact member at the bottom of the first groove. The end face of the outer rope buckle has a locking groove and a second rope hole. When the inner rope buckle and the outer rope buckle are inserted, and the impact member presses the expansion member to lock the expansion member into the locking groove, the first rope hole and the second rope hole are aligned to facilitate threading rope. The spring is used to move the inner rope buckle outward to misalign the first rope hole and the second rope hole. The spring is installed at the bottom of the inner rope buckle. The self-locking rope buckle provided by this utility model can prevent the rope buckle from falling apart during transportation by locking the inner rope buckle and the outer rope buckle. However, it adjusts the rope in a single line and does not provide a solution for tidying up the rope after adjustment. The rope is still messy after the rope buckle is adjusted. Summary of the Invention

[0003] The purpose of this invention is to provide a beautiful and practical buckle that can quickly adjust and fix the relative length of the rope, enabling rapid and effective bidirectional adjustment and fixation.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] This utility model provides a knotting buckle, comprising a buckle base, two sliding plugs, and a return spring. The buckle base has a sliding sleeve at its upper part, with two sets of through-holes symmetrically arranged on its sidewalls. The inner side of each through-hole has a limiting groove, and the outer side has a limiting flange. The bottom of the inner wall of the sliding sleeve has an anti-rotation guide groove, and both ends of the sliding sleeve have protruding guide grooves. The lower part of the buckle base has a rope hook with a locking point inside. The sliding plugs have a spring-loaded hole and a limiting protrusion on their inner side, a pressing cap on their outer side, and a rope passage hole in the middle. The lower side of the sliding plugs has... It features an anti-rotation guide rail; two sliding plugs are inserted from both ends of the sliding sleeve, and return springs are embedded in the two spring holes. The two sliding plugs are pressed outwards respectively, and two ropes pass through their corresponding rope holes and rope passage holes. Under the pressure of the return springs, the ropes are fixed within the gaps formed by the rope holes and rope passage holes. Pressing the sliding plug in one direction increases the gap between the rope holes and rope passage holes, allowing the corresponding rope to be easily pulled for adjustment. Simultaneous pressing of the sliding plug increases the gaps in both sets of rope holes and rope passage holes, allowing both ropes to be easily pulled for adjustment. The adjusted rope can be secured by entering the rope hook through the locking point. The anti-rotation guide groove and anti-rotation guide rail work together to prevent the sliding plugs from deflecting during sliding within the sliding sleeve, ensuring that the rope holes and rope passage holes are relatively aligned horizontally. The limiting protrusion is inserted into the rope hole through the protrusion guide groove by interference fit. When pressed inward, the limiting groove and the limiting protrusion cooperate to limit the minimum relative distance of the sliding plug in the sliding sleeve. When pressed outward to reset under the elastic stress of the reset spring, the limiting flange and the limiting protrusion cooperate to limit the maximum relative distance of the sliding plug in the sliding sleeve.

[0006] The present invention has the following advantages: the elastic sliding plug and the sliding sleeve cooperate to realize the arbitrary adjustment and fixation of the rope, and the rope hook with locking point is set at the lower part of the buckle to further arrange and fix the rope.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1-3 As shown: The knotting buckle provided by this utility model includes a buckle base 1, two sliding plugs 2, and a return spring 3. The buckle base 1 has a sliding sleeve 11 on its upper part. The sliding sleeve 11 has two sets of through-holes 111 symmetrically arranged on its sidewalls. The through-holes 111 have a limiting groove 1111 on their inner side and a limiting stop 1112 on their outer side. The bottom of the inner wall of the sliding sleeve 11 has an anti-rotation guide groove 112, and both ends of the sliding sleeve 11 have protrusion guide grooves 113. The buckle base 1 has a rope hook 12 at its lower part, with a locking point 121 inside the hook. The sliding plug 2 has a spring-loaded hole 21 and a limiting protrusion 25 on its inner side, a pressing cover 22 on its outer side, and a rope passage hole 24 in its middle. The lower side of the movable plug 2 is provided with an anti-rotation guide rail 23; two sliding plugs 2 are respectively inserted from both ends of the sliding sleeve 11, and the return spring 3 is embedded in the two spring insert holes 21. The two sliding plugs 2 are pressed outwards respectively, and the two ropes pass through the corresponding rope holes 111 and rope passage holes 24 respectively. Under the pressure of the return spring 21, the ropes are pressed into the gap formed by the rope holes 111 and rope passage holes 24 respectively and fixed. When the sliding plug 2 is pressed in one direction to make the gap between the rope holes 111 and rope passage holes 24 larger, the corresponding rope can be easily pulled and adjusted. When the sliding plug 2 is pressed at the same time to make the gaps between the two sets of rope holes 111 and rope passage holes 24 larger, both ropes can be easily pulled and adjusted. The adjusted rope can be inserted into the rope hook 12 through the locking point 121 for arrangement and fixation. The anti-rotation guide groove 112 and the anti-rotation guide rail 23 cooperate to prevent the sliding plug 2 from deflecting during sliding within the sliding sleeve 11, ensuring that the rope hole 111 and the rope passage hole 24 are relatively aligned horizontally. The limiting protrusion 25 is interference-fitted into the rope hole 111 from the protrusion guide groove 113. When pressed inward, the limiting groove 1111 and the limiting protrusion 25 cooperate to limit the minimum relative distance of the sliding plug 2 within the sliding sleeve 11. When pressed outward to reset under the elastic stress of the return spring 3, the limiting stop 1112 and the limiting protrusion 25 cooperate to limit the maximum relative distance of the sliding plug 2 within the sliding sleeve 11.

[0016] The present invention has the following advantages: the elastic sliding plug 2 and the sliding sleeve 11 cooperate to realize the arbitrary adjustment and fixation of the rope, and the rope hook 12 with locking point 121 is provided at the lower part of the buckle 1 to further arrange and fix the rope.

[0017] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, and all such modifications fall within the scope of the claims of the present utility model and should be protected by patent law.
