Description

Technical Field

[0001] This utility model relates to the field of rope buckle technology, and in particular to a rope stop buckle. Background Technology

[0002] Loop stoppers are extremely common in daily life, widely used in shoes, hats, backpacks, and other items. They are primarily used to secure and adjust ropes to tighten the loops. There are two basic types of common loop stoppers: one is the general loop stopper, such as... Figure 1 As shown, by pressing the spring-loaded fastening component, the rope slides smoothly in the channel, and then the internal spring force presses the rope to form a locked state; another type is a flat press-lock rope stop, such as... Figure 2 As shown, one end of its outer shell is sewn onto the fabric, and it automatically locks itself through the rebound force of the internal plastic spring. This small, flat, press-to-lock buckle can be tightened or loosened with one hand.

[0003] However, existing cord stoppers have several problems. Generally, cord stoppers use a two-part fastening system, relying on internal plastic springs to create locking force. Because the direction of the squeezing force is the same as the direction of hand pressure, the resistance to achieve the cord stopping effect is relatively high, resulting in a poor pressing experience. Furthermore, the parts are prone to detachment or loss. Another type of cord stopper uses an end-pressing mechanism, with a central axle forming a lever principle to increase locking force. While theoretically enhancing locking force, in practice, it requires both hands. One hand must press the fastening part with the plastic spring to release the cord, while the other hand pulls the cord to allow it to slide smoothly through the channel, making the tightening and loosening of the cord inconvenient. Locking solely based on the plastic spring's compression results in poor stability and a high risk of locking failure. Additionally, the mold production for this structure is unstable, product assembly is cumbersome, and there is a risk of it falling off.

[0004] In summary, how to effectively solve the problems of inconvenient operation and poor locking stability of existing rope and strap stop buckles is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a rope stop buckle that solves the problems of inconvenient operation and poor stability of existing rope stop buckles.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A rope stopper includes an outer part and an inner part hinged to the outer part. The inner part has a pressing part and a limiting point. The outer part has an abutting part and a limiting spring. The bottom surface of the outer part has a rope opening. The inner part has a rope hole for a rope to pass through the rope opening. After the rope passes through the rope hole, the inner part is flipped to reduce the gap between the pressing part and the abutting part until the limiting point is engaged under the limiting spring, and the pressing part presses the rope against the abutting part to fix it.

[0008] The abutting part and the limiting spring have a dividing channel, which is configured to provide clearance space for the elastic deformation of the abutting part when the pressing part presses the rope against the abutting part.

[0009] Optionally, the inner component and the outer component are hinged together by a hinge shaft, and the central axis of the pressing part is eccentrically set with respect to the rotation axis of the hinge shaft.

[0010] Optionally, the hinge shaft is disposed on both sides of the inner component, and the outer component has hinge holes on both sides that mate with the hinge shaft. The inner wall of the outer component has a guide groove that communicates with the hinge holes. The surface of the guide groove that contacts the end face of the hinge shaft is an inwardly inclined surface from the edge of the outer component toward the hinge hole.

[0011] Optionally, the surface of the pressing part is provided with a first rope-stopping friction texture, and the surface of the abutting part away from the dividing channel is provided with a second rope-stopping friction texture. The first rope-stopping friction texture and the second rope-stopping friction texture can interlock with each other, and the rope is interlocked between the first rope-stopping friction texture and the second rope-stopping friction texture.

[0012] Optionally, the limiting spring includes a fixed end and a movable spring connected to the upper part of the fixed end. The fixed end is connected to the inner wall of the outer part. The movable spring faces the limiting point to engage with the limiting point. The fixed end faces the abutment portion. The dividing channel is located between the fixed end and the abutment portion.

[0013] Optionally, after the snap-fit ​​is engaged, the position of the movable spring is higher than the limiting point. When the limiting point is pressed under the movable spring, the movable spring and the limiting point exchange contact positions and make a sound.

[0014] Optionally, the rope hole and the pressing part are located on the side close to the outer part, the limiting point is provided at the rope inlet end of the lower frame of the rope hole, the limiting point is a protrusion extending outward from the lower frame, and both the protrusion and the pressing end of the movable spring are arc-shaped.

[0015] Optionally, the frame of the rope hole is continuous, the inner surface of the lower frame is inclined downward from the rope inlet end to the rope outlet end, a stepped surface is formed between the end face of the rope inlet end and the top surface of the limiting point, and the end face of the movable spring contactes the end face of the rope inlet end.

[0016] Optionally, there is a gap between the sidewall of the movable spring and the inner wall of the outer component, and the width of the limiting point is equal to the width of the movable spring.

[0017] Optionally, the outer part is provided with a limiting groove for accommodating the rope hole. After fastening, the bottom surface of the frame of the rope hole fits against the bottom surface of the limiting groove, and the top surface of the limiting point abuts against the bottom surface of the movable spring.

[0018] The beneficial effect of this utility model is that the rope stop buckle provided by this utility model has a rope-passing opening on the bottom surface of the outer part near the hinge axis, and a rope-passing hole at the end of the inner part away from the hinge axis. The rope first passes through the rope-passing opening and then enters the rope-passing hole. When the rope passes through the rope-passing hole, the end of the rope can be pulled to adjust the direction of pulling the rope, which is flexible.

[0019] When the inner part is flipped over, the pressing part of the inner part and the abutting part of the outer part come into contact with each other. Through the cooperation of the pressing part and the abutting part, the rope is pressed tight, thereby fixing the rope.

[0020] The outer component's limiting spring has a certain degree of elasticity, and the limiting spring and the inner component's limiting point cooperate to form a snap-fit ​​structure. When the inner component is flipped to a certain position, the limiting point will lock under the limiting spring, thereby fixing the position of the inner component and ensuring that the inner component will not easily loosen after the fixed rope is secured, ensuring that the pressing part and the contact part are in a stable state of continuously pressing the rope.

[0021] After the cord is passed through the threaded hole, the inner component begins to rotate. As the inner component rotates, its pressing part gradually approaches the abutting part of the outer component. During this process, the gap between the pressing part and the abutting part gradually decreases. When the inner component rotates to the appropriate position, its limiting point will engage under the limiting spring. During this process, the compressive force between the pressing part and the abutting part increases, as does the friction between the pressing part, the abutting part, and the cord, gradually pressing the cord tightly between them. Due to the locking action of the limiting point and the limiting spring, the inner component is fixed in this position, and the cord is firmly secured in the device, achieving cord locking and effectively preventing the cord from loosening or slipping.

[0022] During the process of pressing the rope between the pressing part and the contact part, the pressing part applies a certain force to the contact part. This force causes the contact part to tilt away from the pressing part. To prevent this tilting from causing the limiting spring to also move away from the pressing part, a dividing channel can be provided between the contact part and the limiting spring. When the pressing part presses the rope against the contact part, the compressive force causes the contact part to undergo elastic deformation. At this time, the dividing channel provides clearance for the elastic deformation of the contact part. Within this channel, the deformation of the contact part is released, allowing the contact part and the limiting spring to separate from each other, thus ensuring the independence of the limiting spring. Even under the pressure of the pressing part, the limiting spring will not deform or shift.

[0023] The fixed position of the limiting spring provides a stable condition for its engagement with the limiting point. Since the limiting spring will not change position due to external force, the limiting point can be smoothly locked under the limiting spring.

[0024] The rope stop buckle provided by this utility model has a tight fit between the pressing part and the abutting part when fixing the rope, and firmly fixes the rope in place through the squeezing action, effectively preventing it from slipping. Moreover, the rope stop buckle is stable in the locking state when fixing the rope, ensuring the stability of the rope during use. Attached Figure Description

Detailed Implementation

[0039] The core of this utility model is to provide a rope stop buckle, which solves the problems of inconvenient operation and poor stability of existing rope stop buckles.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please refer to Figures 3 to 11 , Figure 3 A schematic diagram of the rope stop buckle provided in a specific embodiment of this utility model; Figure 4 An exploded view of a rope stopper; Figure 5 This is a cross-sectional view of a rope stopper. Figure 6 This is a schematic diagram of the external component; Figure 7 This is a structural diagram of the internal components; Figure 8 This is another structural diagram of the internal components; Figure 9 This is a schematic diagram showing the internal and external components not connected. Figure 10 This is a schematic diagram showing the connection between the internal and external components. Figure 11 This is a diagram illustrating how a rope stopper is used to lock a rope.

[0042] In one specific embodiment, the rope stop buckle provided by this utility model includes an outer part 2 and an inner part 1 hinged to the outer part 2. The inner part 1 is provided with a pressing part 13 and a limiting point 12. The outer part 2 is made of plastic and is provided with a contact part 8 and a limiting spring piece 4. The bottom surface of the outer part 2 has a rope opening 6. The inner part 1 is provided with a rope hole 9. The rope hole 9 allows the rope to pass through the rope opening 6. After the rope passes through the rope hole 9, the inner part 1 is flipped to reduce the gap between the pressing part 13 and the contact part 8 until the limiting point 12 is stuck under the limiting spring piece 4, and the pressing part 13 presses the rope against the contact part 8 to fix it.

[0043] The abutting part 8 and the limiting spring 4 have a dividing channel 11. The dividing channel 11 is configured to provide clearance space for the elastic deformation of the abutting part 8 when the pressing part 13 presses the rope against the abutting part 8.

[0044] In the above structure, the rope stop buckle includes an outer part 2 and an inner part 1, which are connected by a hinge. The inner part 1 can rotate freely relative to the outer part 2 within a certain angle range, thereby realizing the fixing and releasing operation of the rope.

[0045] The bottom surface of the outer component 2 has a rope-passing opening 6 near the hinge shaft 10. The rope-passing opening 6 is the entrance for the rope to enter the device. The rope passes between the inner component 1 and the outer component 2 from bottom to top. The inner component 1 has a rope-passing hole 9 at its end away from the hinge shaft 10. The rope-passing hole 9 is a hole on the inner component 1 through which the rope passes. The rope first passes through the rope-passing opening 6 and then enters the rope-passing hole 9. When the rope passes through the rope-passing hole 9, it can be pulled at the end to adjust the direction of the rope. Preferably, the shape and size of the rope-passing opening 6 and the rope-passing hole 9 match the rope to ensure smooth passage. For example, they are rectangles slightly larger than the rope size, which are easy to process and have strong adaptability.

[0046] When the inner part 1 is flipped over, the pressing part 13 of the inner part 1 and the abutting part 8 of the outer part 2 come into contact with each other. Through the cooperation of the pressing part 13 and the abutting part 8, the rope is pressed tight, thereby fixing the rope.

[0047] The limiting spring 4 of the outer component 2 has a certain elasticity. The limiting spring 4 and the limiting point 12 of the inner component 1 cooperate to form a snap-fit ​​structure. When the inner component 1 is flipped to a certain position, the limiting point 12 will lock under the limiting spring 4, thereby fixing the position of the inner component 1, preventing the inner component 1 from tilting up and rotating, ensuring that the inner component 1 will not easily loosen after the rope is fixed, and ensuring that the pressing part 13 and the abutting part 8 are in a stable state of continuously pressing the rope.

[0048] In use, first insert the rope through the rope-through hole 6 on the bottom surface of the outer part 2. The rope follows the guide of the rope-through hole 6 into the interior of the device and continues through the rope-through hole 9 of the inner part 1. At this time, the inner part 1 is in an unflipped state. The rope-through hole 9 and the rope-through hole 6 cooperate with each other, allowing the rope to pass smoothly through the outer part 2 and the inner part 1.

[0049] After the rope passes through the rope hole 9, the inner part 1 begins to flip. As the inner part 1 flips, the pressing part 13 of the inner part 1 gradually approaches the abutting part 8 of the outer part 2. During this process, the gap between the pressing part 13 and the abutting part 8 gradually decreases. When the inner part 1 flips to the appropriate position, the limiting point 12 of the inner part 1 will be locked under the limiting spring 4. During this process, the squeezing force between the pressing part 13 and the abutting part 8 increases, and the friction between the pressing part 13 and the abutting part 8 and the rope increases, gradually pressing the rope between them. The rope-stopping engagement point 15, where the pressing part 13 and the abutting part 8 press the rope, is at the top. At the rope-stopping engagement point 15, the gap between the pressing part 13 and the abutting part 8 is the smallest. Below the rope-stopping engagement point 15, the gap between the pressing part 13 and the abutting part 8 gradually increases. Due to the locking action of the limiting point 12 and the limiting spring 4, the inner part 1 is fixed in this position, and the rope is firmly fixed in the device, realizing the locking of the rope and effectively preventing the rope from loosening and slipping.

[0050] When the cord needs to be released, simply lift the inner part 1 upwards. The inner part 1 flips in the opposite direction around the hinge axis 10, separating the pressing part 13 from the abutting part 8, releasing the cord between the pressing part 13 and the abutting part 8. The cord can then be freely pulled out from the channel between the pressing part 13 and the abutting part 8, easily releasing the cord. It should be noted that the cord can be pulled up to open the engagement angle between the inner part 1 and the outer part 2, thereby loosening the cord. The cord can be fixed and released through a simple flipping action, making the operation simple and quick, suitable for one-handed operation. Preferably, the pressing part conforms to the natural grip posture of the human hand, making the pressing process more comfortable, facilitating pinching and applying force, and improving the user's comfort during operation.

[0051] During the process of pressing the rope with the pressing part 13 and the abutting part 8, the pressing part 13 applies a certain force to the abutting part 8. This force causes the abutting part 8 to tilt away from the pressing part 13. To prevent this tilting from causing the limiting spring 4 to also move away from the pressing part 13, a dividing channel 11 can be provided between the abutting part 8 and the limiting spring 4. When the pressing part 13 presses the rope against the abutting part 8, the compressive force causes the abutting part 8 to undergo elastic deformation. At this time, the dividing channel 11 can provide clearance for the elastic deformation of the abutting part 8. Within this channel, the deformation of the abutting part 8 is released, allowing the abutting part 8 and the limiting spring 4 to separate from each other, thereby ensuring the independence of the limiting spring 4. Even when the pressing part 13 is pressing, the limiting spring 4 will not deform or shift.

[0052] The position of the limiting spring 4 is fixed, providing a stable condition for its engagement with the limiting point 12. Since the limiting spring 4 will not change position due to external force, the limiting point 12 can smoothly snap into place below the limiting spring 4. This structural design not only ensures the stability of the rope stop buckle when fixing the rope, but also improves its overall reliability.

[0053] The cord stopper provided by this utility model features a tight fit between the pressing part 13 and the abutting part 8 when fixing a cord. Through compression, the cord is firmly secured in place, effectively preventing slippage. Furthermore, the cord stopper maintains a stable locking state when fixing the cord, ensuring the stability of the cord during use. The overall structure of the cord stopper is relatively simple, making the device easy to manufacture, reducing production costs, and facilitating daily maintenance. It has an extremely wide range of applications, covering almost all occasions requiring cord fixing, such as shoes, hats, bags, and clothing, demonstrating strong versatility.

[0054] Based on the above specific embodiments, the inner part 1 and the outer part 2 are hinged by the hinge shaft 10, and the central axis of the pressing part 13 is eccentrically set with respect to the rotation axis of the hinge shaft 10.

[0055] In one specific embodiment, the hinge shaft 10 is the connecting component between the inner part 1 and the outer part 2. The inner part 1 rotates relative to the outer part 2 around the hinge shaft 10. The central axis of the pressing part 13 is eccentrically set with respect to the rotation axis of the hinge shaft 10. In other words, the central axis of the pressing part 13 and the rotation axis of the hinge shaft 10 do not coincide, and there is a certain eccentricity. This eccentric setting causes the gap between the pressing part 13 and the abutting part 8 to change during the rotation of the inner part 1, resulting in different squeezing effects at different rotation angles.

[0056] Specifically, after the rope passes through the rope hole 9, the inner part 1 begins to flip. Since the central axis of the pressing part 13 is eccentrically positioned relative to the flipping axis of the hinge shaft 10, as the inner part 1 flips, the rotation radius of the pressing part 13 increases, and the pressing part 13 gradually approaches the abutting part 8 of the outer part 2. The gap between the pressing part 13 and the abutting part 8 decreases, increasing the squeezing force of the pressing part 13 on the abutting part 8, which in turn increases the squeezing force on the rope, thus increasing the frictional force on the rope. When the inner part 1 flips to a certain angle, the pressure generated by the pressing part 13 and the abutting part 8 tightens the rope. This eccentric design ensures that when fixing the rope, the downward pressure of the inner part 1 becomes increasingly tighter, forming a strong engagement angle, and the pressure distribution is more uniform, achieving a better rope-stopping effect.

[0057] When it is necessary to release the rope, simply reverse the inner part 1. Due to the eccentric setting, the pressing part 13 will gradually move away from the abutting part 8, and the pressure will gradually decrease until the rope can move freely.

[0058] The aforementioned eccentric design allows the pressure-retaining part 13 to generate greater pressure when fixing the rope, thereby securing the rope more firmly and preventing it from slipping during use. During operation, users can apply force more easily, further improving the comfort of operation.

[0059] Based on the above specific embodiments, the hinge shaft 10 is provided on both sides of the inner part 1, and the outer part 2 is provided on both sides with hinge holes 7 that cooperate with the hinge shaft 10. The hinge shaft 10 is connected in the hinge holes 7, and the inner part 1 can flexibly rotate around the hinge shaft 10, thereby realizing the fixing and releasing operation of the rope through the rotating action.

[0060] Of course, it is also possible that the inner part 1 has a hinge hole and the outer part 2 has a hinge shaft, or both the inner part 1 and the outer part 2 have hinge holes, and a separate hinge shaft is connected to the hinge holes of both.

[0061] Based on the above specific embodiments, the inner wall of the outer component 2 is provided with a guide groove 5, which connects to the hinge hole 7 to guide the installation of the hinge shaft 10. Specifically, the surface of the guide groove 5 that contacts the end face of the hinge shaft 10 is an inwardly inclined surface from the edge of the outer component 2 toward the hinge hole 7, that is, the width between the two guide grooves 5 gradually decreases from the edge of the outer component 2 to the hinge hole 7.

[0062] The hinge shaft 10 of the inner component 1 enters the guide groove 5 from the wider position, making the initial insertion of the hinge shaft 10 smoother and reducing resistance during installation. Preferably, the width of the guide grooves 5 at the edges is greater than the distance between the two ends of the hinge shaft 10, allowing the hinge shaft 10 to enter the guide groove 5 more easily.

[0063] Once the hinge shaft 10 enters the guide groove 5, it slides smoothly along the inclined surface of the guide groove 5. As the hinge shaft 10 gradually moves inward along the inclined surface, it eventually transitions seamlessly and smoothly into the hinge hole 7, improving the ease of assembly between the inner part 1 and the outer part 2. The hinge shaft 10 rotates within the hinge hole 7, achieving a stable connection and flexible flipping between the inner part 1 and the outer part 2.

[0064] Based on the above specific embodiments, the surface of the pressing part 13 is provided with a first rope-stopping friction texture, and the surface of the abutting part 8 on the side away from the dividing channel 11 is provided with a second rope-stopping friction texture. The first rope-stopping friction texture and the second rope-stopping friction texture can interlock with each other, and the rope is interlocked between the first rope-stopping friction texture and the second rope-stopping friction texture.

[0065] In one specific embodiment, the surfaces of the abutting part 8 and the pressing part 13 that mate are on the side surface away from the dividing channel 11. The mating surfaces of the pressing part 13 and the abutting part 8 are cylindrical surfaces. The mating surface of the pressing part 13 is provided with a first rope-stopping friction texture, and the mating surface of the abutting part 8 is provided with a second rope-stopping friction texture.

[0066] When the rope is placed between the pressing part 13 and the abutting part 8, the first and second rope-stopping friction patterns can interlock when the inner part 1 flips over and presses the rope. This not only increases the contact area between the rope and the abutting part 8 and the pressing part 13, but also generates sufficient friction through the texture structure of the friction patterns, thereby more firmly fixing the rope and preventing it from slipping. Preferably, the friction patterns are toothed, with a larger interlocking force and greater clamping force.

[0067] It should be noted that when the rope is placed between the pressing part 13 and the abutting part 8, the first rope-stopping friction groove and the second rope-stopping friction groove may interlock with each other to press the rope tightly, or they may not interlock with each other but have already tightly clamped the rope in the middle.

[0068] Based on the above specific embodiments, the first rope-stopping friction pattern is located inside the pressing part 13, and the hinge shaft 10 is located outside the first rope-stopping friction pattern, that is, the hinge shaft 10 is located outside the pressing part 13. When the inner part 1 is pressed down, the rotation radius of the pressing part 13 increases, the gap between the pressing part 13 and the abutting part 8 decreases, the squeezing force of the pressing part 13 on the abutting part 8 increases, and the squeezing force of the pressing part 13 and the abutting part 8 on the rope increases, which increases the friction force on the rope, thereby achieving a strong locking effect.

[0069] Based on the above specific embodiments, the outer side of the pressing part 13 has a concave surface, that is, the rear end of the pressing part 13 is an unconventional cylinder, and the inner part 1 and the outer part 2 form a space with an inner groove on the outside, making it more convenient for the rope head to pass through the inner groove of the inner part 1 and the outer part 2 from the bottom.

[0070] Based on the above specific embodiments, the limiting spring 4 includes a fixed end and a movable spring 14 connected to the upper part of the fixed end. The fixed end is connected to the inner wall of the outer part 2. The movable spring 14 faces the limiting point 12 to engage with the limiting point 12. The fixed end faces the abutting part 8. The dividing channel 11 is provided between the fixed end and the abutting part 8.

[0071] In one specific embodiment, the limiting spring 4 mainly consists of two parts: a fixed end and a movable spring 14. The fixed end is firmly connected to the inner wall of the outer part 2, realizing a firm connection between the limiting spring 4 and the outer part 2. Preferably, the fixed end and the inner wall of the outer part 2 are integrally injection molded, so that the limiting spring 4 can withstand a large external force during use without easily shifting or breaking.

[0072] The movable spring 14 is connected to the upper part of the fixed end and has a certain elasticity, allowing it to move up and down flexibly so that it can be smoothly engaged with the limiting point 12 during the engagement process.

[0073] The movable spring 14 faces the limiting point 12. When the inner part 1 is flipped to the appropriate position, the movable spring 14 can tightly lock into the limiting point 12, thereby fixing the position of the inner part 1. This locking structure not only ensures the stability of the inner part 1 when fixing the rope, but also prevents the inner part 1 from loosening due to external forces. Through the tight cooperation between the movable spring 14 and the limiting point 12, the rope stop buckle can firmly fix the rope and prevent it from slipping or loosening during use.

[0074] The fixed end faces the abutment part 8, and the dividing channel 11 is disposed between the fixed end and the abutment part 8, separating the abutment part 8 and the limiting spring 4 from each other, ensuring the independence of the limiting spring 4. When the pressing part 13 and the abutment part 8 are tightening the rope, the abutment part 8 may tilt away from the pressing part 13. The existence of the dividing channel 11 effectively prevents this tilting from causing the limiting spring 4 to shift or deform, thereby ensuring that the limiting spring 4 always remains in the correct position and can smoothly engage with the limiting point 12, optimizing the user experience.

[0075] Based on the above specific embodiments, after the snap-fit, the position of the movable spring 14 is higher than the limiting point 12. When the limiting point 12 is pressed under the movable spring 14, the movable spring 14 collides with the limiting point 12 and makes a sound.

[0076] In one specific embodiment, after the cord stop buckle completes its fastening action, the position of the movable spring piece 14 will be higher than the limiting point 12. This structure can generate a noticeable physical feedback when the limiting point 12 is pressed under the movable spring piece 14. Specifically, when the inner part 1 flips and brings the limiting point 12 close to the movable spring piece 14, the limiting point 12 will gradually be pressed under the movable spring piece 14. During the pressing process of the limiting point 12, the movable spring piece 14 and the limiting point 12 exchange contact positions in the vertical direction. Because the movable spring piece 14 is elastic, it can withstand the force generated when the limiting point 12 is pressed in and can quickly return to its original position, thereby generating a bounce and a sound.

[0077] When using the cord stopper, this audible feedback provides the user with an intuitive operational prompt. Hearing this sound confirms that the movable spring 14 and the limiting point 12 have been correctly engaged, and the cord has been securely fixed.

[0078] Based on the above specific embodiments, the rope hole 9 and the pressing part 13 are located on the side close to the outer part 2, and the limiting point 12 is provided at the rope inlet end of the lower frame of the rope hole 9. The limiting point 12 is a protrusion extending outward from the lower frame. Both the protrusion and the pressing end of the movable spring piece 14 are arc-shaped.

[0079] In one specific embodiment, both the rope hole 9 and the pressing part 13 are located on the side of the inner part 1 closer to the outer part 2. After the rope passes through the rope hole 9, it can be directly pressed by the pressing part 13. The structure is compact, reducing the shaking and displacement of the rope during the fixing process, and the overall stability is good.

[0080] The limiting point 12 is located on the lower edge of the rope hole 9, near the rope inlet end of the movable spring 14. The lower edge extends outward to form a protrusion, namely the limiting point 12. It should be noted that the limiting point 12 can be one or more points, or it can be a limiting edge connected to the edge of the lower edge. The connection between the protrusion and the lower edge not only increases the structural strength of the limiting point 12, but also makes the setting of the limiting point 12 simpler and allows the position of the limiting point 12 to fit more tightly with the movable spring 14.

[0081] Both the limiting point 12 and the pressing end of the movable spring 14 are rounded. This rounded shape allows the limiting point 12 to enter the space under the movable spring 14 more smoothly, reducing jamming; it also reduces friction between the limiting point 12 and the movable spring 14, extending the service life of the components.

[0082] Based on the above specific embodiments, the frame of the rope hole 9 is continuous, the inner surface of the lower frame is inclined downward from the rope inlet end to the rope outlet end, a stepped surface is formed between the end face of the rope inlet end and the top surface of the limiting point 12, and the end face of the movable spring piece 14 is in contact with the end face of the rope inlet end.

[0083] In one specific embodiment, the frame of the rope hole 9 is a continuous structure, which not only enhances the overall strength of the rope hole 9, but also prevents the rope from getting stuck or coming out of the frame opening during the passing process, ensuring the smoothness of the rope passing through.

[0084] The inner surface of the lower frame is inclined downwards from the rope inlet end to the rope outlet end. The inclined lower frame guides the rope smoothly into the rope hole 9, reducing the resistance when the rope enters and allowing the rope to pass through the rope hole 9 more easily. After the rope passes through the rope hole 9, the inclined lower frame guides the rope end to extend towards the side closer to the outer part 2, preventing the rope end from sticking up after exiting the rope hole 9 and reducing the occurrence of snagging.

[0085] A stepped surface is formed between the end face of the rope inlet and the top surface of the limiting point 12. The horizontal surface of the stepped surface is the top surface of the limiting point 12, and the vertical surface is the end face of the rope inlet. When the movable spring 14 engages with the limiting point 12, the bottom surface of the movable spring 14 presses against the top surface of the limiting point 12, and the end face of the movable spring 14 is in contact with or has a small gap from the end face of the rope inlet. The end face of the rope inlet provides lateral limiting for the movable spring 14, preventing misalignment and locking of the movable spring 14 or the limiting point 12, and ensuring that the movable spring 14 and the limiting point 12 can be correctly locked together. At the same time, the end face of the rope inlet has a suppressive effect on the bounce of the movable spring 14, allowing the movable spring 14 to quickly return to a stable state after the locking is completed.

[0086] Based on the above specific embodiments, there is a gap between the side wall of the movable spring 14 and the inner wall of the outer part 2, and the width of the limiting point 12 is equal to the width of the movable spring 14.

[0087] In one specific embodiment, there is a certain gap between the side wall of the movable spring 14 and the inner wall of the outer part 2, that is, there is no contact between the movable spring 14 and the inner wall of the outer part 2. The gap provides the movable spring 14 with a space for movement, so that it can freely perform elastic movements such as extension, rebound and deformation when subjected to the external force of the limiting point 12, ensuring that the limiting point 12 can smoothly enter under the movable spring 14 and be firmly locked.

[0088] The width of the limiting point 12 is equal to the width of the movable spring 14. The mating length of the limiting point 12 and the movable spring 14 is the longest, maximizing the contact area after snapping, reducing the jamming or loosening caused by size mismatch, and improving the reliability and stability of the snapping.

[0089] Based on the above specific embodiments, the outer part 2 is provided with a limiting groove 3 for accommodating the rope hole 9. After fastening, the bottom surface of the frame of the rope hole 9 fits with the bottom surface of the limiting groove 3, and the top surface of the limiting point 12 abuts against the bottom surface of the movable spring piece 14.

[0090] In one specific embodiment, the outer component 2 is provided with a limiting groove 3, and the rope hole 9 is accommodated in the limiting groove 3. In the fastened state, the bottom surface of the frame of the rope hole 9 is tightly fitted with the bottom surface of the limiting groove 3, and the limiting groove 3 provides a stable support platform for the rope hole 9, ensuring that the inner component 1 can be accurately positioned after fastening.

[0091] While the bottom surface of the frame of the rope hole 9 is in contact with the bottom surface of the limiting groove 3, the top surface of the limiting point 12 abuts against the bottom surface of the movable spring piece 14. At this time, the upper and lower surfaces of the rope hole 9 are vertically limited by the limiting groove 3 and the movable spring piece 14 respectively, ensuring that the inner part 1 is firmly fixed in the outer part 2, preventing the inner part 1 from loosening or shifting due to external force during use, and improving the overall stability of the device.

[0092] Preferably, the shape and size of the limiting groove 3 match the frame of the rope hole 9. The limiting groove 3 restricts the lateral position of the rope hole 9, so that the inner part 1 can be accurately aligned when fastened, preventing the inner part 1 from deflecting in the outer part 2.

[0093] Based on the above specific embodiments, the bottom surface of the outer part 2 is hollowed out from the hinge hole 7 to the limiting groove 3. The abutting part 8 is connected to the inner wall of the outer part 2. The hollowed-out area between the abutting part 8 and the hinge hole 7 forms a rope-passing opening 6. The hollowed-out area between the limiting groove 3 and the fixed end forms a slot. The limiting point 12 is locked in the slot.

[0094] In one specific embodiment, the area from the hinge hole 7 to the limiting groove 3 on the bottom surface of the outer component 2 is hollowed out. This not only reduces the overall weight of the device, making it lighter and easier to carry and use, but also divides the functional areas, ensuring that the various components can work together more efficiently. Specifically, the abutment part 8 is connected to the inner wall of the outer component 2, and the hollowed-out area between the abutment part 8 and the hinge hole 7 forms the rope-threading opening 6. The hollowed-out area between the limiting groove 3 and the fixed end forms a slot. The slot is the receiving position of the limiting point 12, and no other components are placed inside it. Its bottom surface is hollowed out to avoid direct contact between other components and the limiting point 12, reducing interference from other components on the movement of the limiting point 12.
