Description

Technical Field

[0001] This utility model relates to the field of buckles, and more specifically, to a rope buckle that can adjust and fix the relative length of a rope for use. Background Technology

[0002] With the increasing prevalence of buckles, rope buckles 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 the inner rope buckle has a first rope hole for threading the 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 the outer rope buckle has 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 the 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 scattering during transportation by locking the inner rope buckle and the outer rope buckle. However, it does not provide a solution for organizing the rope after adjustment, and the rope is still scattered 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 rope buckle, comprising a fixed base, a sliding base, a hollow gear, a limiting plug, and a return spring. The fixed base has a stepped chamber, a wire-connecting hole communicating with the stepped chamber from the bottom, a stepped groove on the inner wall of the stepped chamber, symmetrical L-shaped sliding grooves and limiting holes on the upper part of the fixed base, a first guide slope on the inner side of the limiting hole, and a wire-connecting groove on the outer side of the lower part of the fixed base. The sliding base has symmetrical L-shaped grooves on both sides that interlock with the L-shaped sliding grooves. The groove has a pull-out bevel and a zigzag hole on its exterior; the sliding seat has two wire-passing holes on its interior side; a spring groove is cut upwards in the middle of the sliding seat; a first spring-embedded hole is provided at the bottom of the spring groove; a support rod protrudes downwards in the middle of the sliding seat; an eccentric shaft is provided at the lower end of the support rod; the hollow gear has rope-pressing teeth on its outer circumference; a blind hole is provided in the axial direction of the hollow gear as a hollow cavity; a second spring-embedded hole with a downward opening is provided in the middle of the limiting plug; limiting protrusions are symmetrically provided on both sides of the limiting plug; a second guide bevel with a downward inclination is provided on the outer side of the limiting protrusion.

[0006] The L-shaped grooves on both sides of the sliding seat and the L-shaped grooves on both sides of the fixed seat interlock, allowing the sliding seat to be slidably embedded in the upper part of the fixed seat. The hollow cavity of the hollow gear covers the eccentric shaft at the end of the support rod, placing the hollow gear in the stepped cavity inside the fixed seat. The limiting protrusions on both sides of the limiting plug are engaged in the limiting holes by the cooperation of the first guide slope and the second slope. The return spring is placed in the spring groove, with one end embedded in the first spring hole and the other end embedded in the second spring hole. Two ropes extend side by side from the parallel hole into the stepped cavity at the bottom of the fixed seat. The fixed seat is held with the palm and middle and ring fingers, and two fingers (thumb and index finger) pinch the pulling slope to overcome the elastic stress of the return spring and pull the sliding seat upward. The hollow gear is pulled away from the stepped groove in the stepped cavity. The ropes pass through the two wire holes in the sliding seat respectively. The pulling slope is released, and the sliding seat is released by the spring of the return spring. Under the action of stress, the hollow gear resets downwards along the position defined by the interlocking of the L-shaped groove and the L-shaped slide. After resetting, pulling any rope upwards will cause the hollow gear to move upwards, increasing the distance between the rope-pressing teeth and the stepped groove, facilitating the passage of the rope and adjusting the relative position between the rope buckle and the rope. Pulling any rope downwards will cause the hollow gear to move downwards, reducing the distance between the rope-pressing teeth and the stepped groove, preventing the rope from passing through, thus fixing the relative position between the rope buckle and the rope. If reverse adjustment is required, pinch the pulling inclined surface to overcome the elastic stress of the reset spring and pull the sliding seat upwards, forcibly pulling the hollow gear to move the rope-pressing teeth away from the stepped groove in the stepped chamber, then the rope can be pulled downwards for reverse adjustment. To better organize the ropes, ropes passing through the thread hole can be folded into the folding hole, and ropes passing through the parallel thread hole can be stored or tied into the cable tray.

[0007] The present invention has the following advantages: the elastic telescopic support rod and the hollow gear cooperate to realize the arbitrary adjustment and fixation of the rope; the pull-out inclined surface on the sliding seat provides convenience for adjusting the sliding seat; and the folded hole and the cable tray groove facilitate further adjustment and arrangement of the rope.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-6 As shown: This utility model provides a rope buckle, including a fixed base 1, a sliding base 2, a hollow gear 3, a limiting plug 4, and a return spring 5. The fixed base 1 has a stepped chamber 11, a parallel hole 111 communicating with the stepped chamber 11 from the bottom, a stepped groove 112 on the inner wall of the stepped chamber 11, an L-shaped sliding groove 12 and a limiting hole 13 symmetrically arranged on the upper part of the fixed base 1, a first guide slope 131 on the inner side of the limiting hole 13, and a wire harness groove 14 on the lower outer side of the fixed base 1; the sliding base 2 has L-shaped grooves 21 symmetrically arranged on both sides that fit into the L-shaped sliding grooves 12. 1. The exterior is provided with a pull-out inclined surface 26 and a folded hole 22; the inner side of the sliding seat 2 is provided with two wire-passing holes 25, the middle of the sliding seat 2 is provided with an upward-splitting spring groove 23, the bottom of the spring groove 23 is provided with a first spring-embedded hole 231, the middle of the sliding seat 2 is provided with a downward-protruding support rod 24, the lower end of the support rod 24 is provided with an eccentric shaft 241; the outer circumference of the hollow gear 3 is provided with a rope-pressing tooth 31, and the hollow gear 3 is provided with a blind hole in the axial direction as a hollow cavity 32; the middle of the limiting plug 4 is provided with a downward-opening second spring-embedded hole 41, the limiting plug 4 is provided with symmetrical limiting protrusions 42 on both sides, and the outer side of the limiting protrusions 42 is provided with a downward-sloping second guide inclined surface 421.

[0022] The L-shaped grooves 21 on both sides of the sliding seat 2 and the L-shaped sliding grooves 12 on both sides of the fixed seat 1 fit together to slidably mount the sliding seat 2 onto the upper part of the fixed seat 1. The hollow cavity 32 of the hollow gear 3 covers the eccentric shaft 241 at the end of the support rod 24, placing the hollow gear 3 inside the stepped chamber 11 of the fixed seat 1. The limiting protrusions 42 on both sides of the limiting plug 4 are engaged into the limiting hole 13 under the cooperation of the first guide inclined surface 131 and the second inclined surface 421. The reset spring 5 is placed in the spring groove 23, with one end embedded in the spring groove 23. The first end is inserted into the first spring recess 231, and the other end is inserted into the second spring recess 41; the two ropes extend side by side from the parallel thread hole 111 into the stepped chamber 11 at the bottom of the fixed seat 1. Hold the fixed seat 1 with your palm and middle and ring fingers, and pinch the pulling inclined surface 26 with two fingers (thumb and index finger) to overcome the elastic stress of the return spring 5 and pull the sliding seat 2 upward. The hollow gear 3 is pulled away from the stepped groove 112 in the stepped chamber 11. The ropes pass through the two thread holes 25 in the sliding seat 2 respectively. Release the pulling inclined surface 26. Under the elastic stress of the return spring 5, the sliding seat 2 returns to its original position along the interlocking position defined by the L-shaped groove 21 and the L-shaped sliding groove 12. After returning to its original position, pulling any rope upwards will cause the hollow gear 3 to move upwards, increasing the distance between the rope-pressing teeth 31 and the stepped groove 112, facilitating the passage of the rope and adjusting the relative position between the rope buckle and the rope. Pulling any rope downwards will cause the hollow gear 3 to move downwards, decreasing the distance between the rope-pressing teeth 31 and the stepped groove 112, preventing the rope from passing through. This fixes the relative position between the rope buckle and the rope. If reverse adjustment is required, pinch the pulling inclined surface 26 to overcome the elastic stress of the return spring 5 and pull the sliding seat 2 upwards. Forcefully pull the hollow gear 3 to make the rope pressing tooth 31 move away from the stepped groove 112 in the stepped chamber 11. Then, pull the rope downwards for reverse adjustment. To better organize the rope, the rope passing through the thread hole 25 can be folded into the folding hole 22, and the rope passing through the parallel thread hole 111 can be stored or tied into the wire harness groove 14.

[0023] The present invention has the following advantages: the elastic telescopic support rod 24 cooperates with the hollow gear 3 to realize arbitrary adjustment and fixation of the rope; the pull-out inclined surface 26 is provided on the sliding seat 2 to facilitate the adjustment of the sliding seat 2; and the folding hole 22 and the wire harness groove 14 are provided to facilitate further adjustment and arrangement of the rope.

[0024] 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.
