Description

Technical Field

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

[0002] A cord buckle is a functional accessory that uses a built-in elastic cord and an adjustable buckle (such as a spring lock or a perforated buckle) to control the tightness of clothing. It can flexibly tighten or loosen the hem of garments and is commonly used in sportswear, windproof clothing, etc., providing windproof warmth, a close fit, and a clean appearance. To use, simply pull the cord to secure it, or press the buckle to release the slot and allow the cord to slide freely; it automatically locks when released.

[0003] However, existing rope buckles have the following drawbacks: the main problem with existing rope buckle technology is that it is "easy to tighten, but cumbersome to loosen." Specifically, when tightened, the elastic rope can be quickly locked with a single pull, making it convenient to operate; however, when adjusting to the loosened state, both hands are required to work together, with one hand pressing down on the buckle to unlock it and the other hand pulling the rope in the opposite direction to release the length. This process is particularly inconvenient in outdoor scenarios such as skiing and rock climbing, where gloves or single-handed gripping are required.

[0004] Therefore, how to provide a rope buckle that can be controlled by one hand throughout the entire process, thereby improving the convenience of adjustment in daily and special environments, is a technical 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 buckle that can be controlled with one hand throughout the entire process, thereby improving the convenience of adjustment in daily and special environments.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rope knot, comprising:

[0008] The outer component has a cavity extending through both ends, and the cavity is provided with an elastic wall;

[0009] The inner component is inserted into the cavity and can move along the first direction. The inner component is provided with a locking part that can engage with the elastic wall and a webbing connecting part for connecting the webbing.

[0010] One of the outer and inner components is provided with a rope-passing hole for the rope to pass through, and the other is provided with a rope-pressing surface for pressing against the rope passing through the rope-passing hole;

[0011] An elastic element is installed in the elastic element placement groove of the inner part, and the elastic element is used to drive the inner part to move within the cavity to clamp the rope in the rope hole.

[0012] Under the action of external force, the elastic wall deforms toward the inner part and can engage with the locking part so that the rope in the rope hole is not compressed by the rope surface; after the external force drives the outer part to overcome the elastic force of the elastic element and move relative to the inner part, the elastic wall disengages from the locking part under its own elastic force.

[0013] In one possible implementation, the outer component has a first opening and a second opening, the cavity connects the first opening and the second opening, and a limiting forearm is provided at the end of the cavity near the first opening. The limiting forearm abuts against one end of the elastic member, and the other end of the elastic member abuts against the end of the elastic member mounting groove opposite to the limiting forearm, so that the elastic member drives the inner component to move toward the second opening.

[0014] In one possible implementation, the elastic wall has a hook on the lower side of the end near the second opening, and a locking part is provided at the end of the inner part near the second opening. The hook is used to engage with the locking part when the elastic wall is pressed down to prevent the inner part from moving toward the second opening.

[0015] In one possible implementation, a guide surface is provided on the upper side of the end of the inner part near the second opening. The guide surface is used to guide the hook foot to move to the locking part and engage with it.

[0016] In one possible implementation, the outer part is provided with two rope pressing surfaces at the end of the first opening, and the two rope pressing surfaces are located on both sides of the inner part in the second direction. The rope threading hole of the inner part corresponds to the rope pressing surface in the second direction, so that the rope through the rope threading hole can be locked or released through the two rope pressing surfaces.

[0017] The second direction is the direction through which the rope hole passes.

[0018] In one possible implementation, the pressing surface is specifically an arc surface, and the outer part is provided with a relief groove of an arc shape for making way for the pressing surface.

[0019] In one possible implementation, the webbing connection portion is a connecting groove and is provided at the end of the inner part away from the locking portion, and the webbing connection portion is a square groove.

[0020] The elastic element is specifically a spring.

[0021] In one possible implementation, the end of the inner part near the first opening is provided with limiting points on both sides in the third direction, the limiting points being used to prevent the inner part from detaching from the outer part in the direction toward the second opening;

[0022] The third direction is perpendicular to the first and second directions.

[0023] In one possible implementation, the outer component has curved surfaces on both sides in the third direction to facilitate gripping during use.

[0024] In one possible implementation, the outer component has elastic walls on both sides in the third direction, and the inner component has a locking part in the third direction that cooperates with the elastic walls.

[0025] Compared to the aforementioned background technology, the present invention provides a rope buckle comprising: an outer component, an inner component, and an elastic component; the outer component has a cavity extending through both ends, and the cavity is provided with an elastic wall; the inner component is inserted into the cavity and is movable along a first direction, and the inner component is provided with a locking part that can engage with the elastic wall and a webbing connecting part for connecting a webbing; one of the outer component and the inner component is provided with a rope hole for a rope to pass through, and the other is provided with a rope pressing surface for pressing the rope passing through the rope hole; the elastic component is installed in the elastic component placement groove of the inner component, and the elastic component is used to drive the inner component to move within the cavity to clamp the rope in the rope hole; the elastic wall deforms toward the inner component under the action of external force and can engage with the locking part so that the rope in the rope hole is not pressed by the rope pressing surface; after the external force drives the outer component to overcome the elastic force of the elastic component and move relative to the inner component, the elastic wall disengages from the locking part under its own elastic force.

[0026] Specifically, the rope buckle has two states: one where the elastic wall is engaged with the locking part, in which case the rope buckle is in a relaxed state; and the other where the elastic wall is disengaged from the locking part, in which case the rope buckle is in a locked state. When a finger presses on the elastic wall, the outer and inner parts move relative to each other, causing the elastic wall to engage with the locking part. During this process, the outer and inner parts overcome the elastic force of the elastic element, preventing the pressure surface from further compressing the rope in the threaded hole. When the elastic wall is not disengaged from the locking part, the rope remains relaxed, requiring no continuous pressing of the rope buckle. Users can freely adjust and retract the elastic rope to achieve the desired relaxation and a continuous loosening effect with a single press. After adjusting the rope, dragging it causes the outer and inner parts to move relative to each other. Since no external force is applied to the elastic wall, it springs back to its original state due to its own elasticity. When the user releases their grip, the inner part moves relative to the outer part under the elastic force of the elastic element, causing the pressure surface to re-press the rope in the threaded hole.

[0050] 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.

[0051] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0053] The purpose of this invention is to provide a rope buckle that can be controlled with one hand throughout the entire process, thereby improving the convenience of adjustment in daily and special environments.

[0054] It should be noted that in this embodiment, the Y direction in the attached figure is defined as the first direction, the Z direction as the second direction, and the X direction as the third direction, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0055] To achieve the above objectives, the present invention provides the following technical solution:

[0056] Please see Figures 1 to 13This embodiment provides a rope buckle, including: an outer component 1, an inner component 2, and an elastic component 3; the outer component 1 has a cavity 103 extending through both ends therethrough, and the cavity 103 is provided with an elastic wall 101; the inner component 2 passes through the cavity 103 and is movable along a first direction, and the inner component 2 is provided with a locking part 204 that can engage with the elastic wall 101 and a webbing connecting part 201 for connecting a webbing 5; one of the outer component 1 and the inner component 2 is provided with a rope hole 202 for a rope 4 to pass through, and the other is provided with a force-bearing part 202 for pressing against the rope hole 202. 2. The rope pressing surface 105 of the rope 4; the elastic element 3 is installed in the elastic element placement groove 203 of the inner part 2, and the elastic element 3 is used to drive the inner part 2 to move in the cavity 103 to clamp the rope 4 in the rope hole 202; the elastic wall 101 deforms towards the inner part 2 under the action of external force and can engage with the locking part 204 so that the rope 4 in the rope hole 202 is not pressed by the rope pressing surface 105; after the outer part 1 is driven by external force to overcome the elastic force of the elastic element 3 and move relative to the inner part 2, the elastic wall 101 disengages from the locking part 204 under its own elastic force.

[0057] It should be noted that the webbing 5 in this application is fixed, therefore, the inner part 2 connected by the webbing connecting part 201 will also be fixed, but the outer part 1 and the inner part 2 will move relative to each other in the first direction; at the same time, the rope 4 in this application is also fixed at one end and the other end can move freely; when adjusting the rope 4 in this application, the free end of the rope 4 is adjusted.

[0058] In this application, the outer part 1 is an injection molded part, which can be integrally formed by injection molding. Its elastic wall 101 always tends to move away from the cavity 103 inside the outer part 1. In addition, the elastic element 3 in this application is specifically a spring. Of course, the elastic element 3 can also be other parts with the same effect according to the actual situation.

[0059] In this application, the rope-pressing surface 105 and the rope-threading hole 202 are used to lock and loosen the rope 4 that passes through it. This application provides two embodiments. In one embodiment, the rope-pressing surface 105 and the rope-threading hole 202 are located at the same end of the webbing connection portion 201 on the inner part 2, specifically as follows: Figures 1 to 13 In another embodiment, the rope-pressing surface 105 and the rope-threading hole 202 are located on the inner part 2 at the end away from the webbing connection portion 201, specifically as follows: Figures 14 to 16 .

[0060] In this application, the elastic element 3 is designed to ensure that the inner element 2 and the outer element 1 always have a tendency to move relative to each other, thereby increasing the area where the rope pressing surface 105 and the rope hole 202 overlap, thus locking the rope 4 passing through the rope hole 202. The cooperation between the elastic wall 101 and the locking part 204 keeps the inner element 2 and the outer element 1 in a relatively stationary state. At the same time, in their stationary state, the area where the rope pressing surface 105 and the rope hole 202 do not overlap, allowing the rope 4 inside the rope hole 202 to slide freely.

[0061] In general, the rope buckle has two states: one is that the elastic wall 101 is engaged with the locking part 204, in which case the rope buckle is in a relaxed state; the other is that the elastic wall 101 is separated from the locking part 204, in which case the rope buckle is in a locked state. Specifically, when a finger presses on the elastic wall 101, the outer part 1 and the inner part 2 move relative to each other, causing the elastic wall 101 to engage with the locking part 204. During this process, the outer part 1 and the inner part 2 overcome the elastic force of the elastic element 3, preventing the pressure surface 105 from continuing to press the rope 4 inside the rope hole 202. Furthermore, when the elastic wall 101 is not separated from the locking part 204, the rope 4... It will always be in a relaxed state. At this time, it can be in a continuously relaxed state without the need for continuous pressing of the rope buckle. The user can freely adjust and retract the elastic rope to achieve the purpose of relaxation adjustment and the effect of continuous relaxation with a single press. After the user has adjusted the rope 4, he drags the rope 4 to make the outer part 1 and the inner part 2 move relative to each other. At this time, since no external force is applied to the elastic wall 101, it will bounce back to its original state under its own elasticity. In this way, after the user releases his hand, the inner part 2 will move relative to the outer part 1 under the elastic force of the elastic part 3, so that the rope pressing surface 105 presses the rope 4 in the rope hole 202 again.

[0062] In one possible implementation, the outer component 1 has a first opening 106 and a second opening 107. The cavity 103 connects the first opening 106 and the second opening 107. A limiting forearm 104 is provided at the end of the cavity 103 near the first opening 106. The limiting forearm 104 abuts against one end of the elastic member 3. The other end of the elastic member 3 abuts against the end of the elastic member mounting groove 203 away from the limiting forearm 104, so that the elastic member 3 drives the inner component 2 to move toward the second opening 107.

[0063] Specifically, in the first embodiment, the outer component 1 is a cylindrical structure with a first opening 106 and a second opening 107 at its two ends, respectively. The cavity 103 is the space between the two, and the elastic wall 101 is disposed on the uppermost sidewall of the outer component 1. It should be noted that, in this embodiment, in order to ensure smooth relative movement between the inner component 2 and the outer component 1, and to ensure stability during relative movement, the cross-section of the cavity 103 is approximately a figure-eight shape. The corresponding cross-sectional shape of the inner component 2 can be matched with the internal space of the cavity 103, as shown in the figure below. Figures 8 to 10 As shown.

[0064] In this embodiment, a limiting forearm 104 is provided inside the cavity 103 near the end of the first opening 106. The limiting forearm 104 is provided such that the area of ​​the first opening 106 is smaller than the area of ​​the second opening 107. In practical applications, the limiting forearm 104 will abut against one end of the elastic member 3, thereby preventing the inner member 2 from detaching from the first opening 106 in the direction towards the first opening 106. It can be understood that in this embodiment, the elastic member 3 will be installed in the elastic member placement groove 203, specifically as follows: Figure 7 As shown, one end of the elastic member 3 abuts against the end of the elastic member mounting groove 203 away from the limiting forearm 104; in this way, the elastic member 3 will be installed between the inner member 2 and the outer member 1, and the elastic member 3 always tends to push the inner member 2 away from the outer member 1 in the direction away from the rope hole 202, so that the rope pressing surface 105 will continuously lock the rope 4 in the rope hole 202.

[0065] In one possible implementation, the elastic wall 101 has a hook 102 on the lower side of the end near the second opening 107, and a locking part 204 is provided on the end of the inner part 2 near the second opening 107. The hook 102 is used to engage with the locking part 204 when the elastic wall 101 is pressed down, so as to prevent the inner part 2 from moving toward the second opening 107.

[0066] Specifically, such as Figure 7 As shown, in this embodiment, the elastic wall 101 has a hook-shaped foot 102 on the lower side of its end near the second opening 107. Similarly, the locking part 204 of the inner component 2 is also located near the end of the inner component 2. Thus, when the inner component 2 moves a certain distance relative to the outer component 1 towards the first opening 106, if pressure is applied to the elastic wall 101, causing it to press down, the hook foot 102 will engage the locking part 204, preventing the inner component 2 from continuing to move relative to the outer component 1 towards the second opening 107. Furthermore, the locking part 204 in this embodiment is an inclined surface, specifically as shown... Figure 7 and Figure 12 As shown, its tilt direction is deflected counterclockwise at a certain angle with the midpoint of the inner part 2 as the center, so that the elastic wall 101 cannot naturally bounce upward due to the reaction force transmitted by the locking part 204, so that the rope buckle will be in a locked state.

[0067] In one possible implementation, the upper side of the inner part 2 near the second opening 107 is provided with a guide surface 205, which is used to guide the hook 102 to move to the locking part 204 and engage with it.

[0068] Understandably, in order to ensure that the inner part 2 and the outer part 1 can move relative to each other when the elastic wall 101 is pressed down, a guide surface 205 is provided at the position of the inner part 2 near the hook foot 102 of the elastic wall 101. The guide surface 205 is an inclined surface, that is, the guide surface 205 is lower on the left and higher on the right. In this way, when the hook foot 102 abuts against the guide surface 205, the inner part 2 moves to the right relative to the outer part 1, that is, the inner part 2 and the outer part 1 move away from each other.

[0069] In addition, in this embodiment, the guide surfaces 205 are symmetrically arranged on both sides of the inner component 2, that is, on both sides in the third direction, and both guide surfaces 205 can cooperate with the hook foot 102.

[0070] In one possible implementation, the outer component 1 is provided with two rope-pressing surfaces 105 at the end of the first opening 106, and the two rope-pressing surfaces 105 are located on both sides of the inner component 2 in the second direction. The rope hole 202 of the inner component 2 corresponds to the rope-pressing surfaces 105 in the second direction, so that the rope 4 of the rope hole 202 can be locked or released through the two rope-pressing surfaces 105; the second direction is the through direction of the rope hole 202.

[0071] In the first embodiment, the rope-threading hole 202 is provided on the inner part 2, while the rope-pressing surface 105 is provided at the end where the first opening 106 of the outer part 1 is located. The three together form a shape similar to the second direction, that is, the vertical direction. Figure 13 In the structure, when the rope buckle is in its natural state, that is, the hook 102 is not engaged with the locking part 204 and the rope buckle is not under any tension, the inner part 2 and the outer part 1 move towards each other under the action of the elastic part 3. In this way, the two rope pressing surfaces 105 and the rope hole 202 are interlocked to lock the rope 4. When the user holds the outer part 1 and drags the outer part 1, the outer part 1 moves to the left because the inner part 2 is fixed by the webbing 5. This causes the rope pressing surface 105 to move away from the rope 4 in the rope hole 202, and at the same time, the elastic wall 101 is pressed down to keep the rope buckle in a relaxed state. In this way, the free end of the rope 4 can be adjusted.

[0072] In one possible implementation, the rope pressing surface 105 is specifically an arc surface, and the outer part 1 is provided with a relief groove 108 with an arc structure for making way for the rope pressing surface 105.

[0073] Understandably, in order to better lock the rope 4, the pressing surface 105 is set as an arc-shaped surface that fits the outer periphery of the rope 4. This increases the contact area between the pressing surface 105 and the rope 4, thereby increasing the friction between them and ensuring a better locking effect.

[0074] In one possible implementation, the webbing connection portion 201 is a connecting groove and is provided at the end of the inner part 2 away from the locking portion 204, and the webbing connection portion 201 is a square groove; the elastic member 3 is specifically a spring.

[0075] In this embodiment, the webbing connecting part 201 is provided at the right end of the inner part 2, and its shape is square. The square structure of the webbing connecting part 201 can better connect the webbing 5.

[0076] In addition, the webbing connector 201 can also be a rivet or other connection method, as long as it can achieve a fixed connection with the webbing 5.

[0077] In one possible implementation, the inner part 2 is provided with limiting points 206 on both sides of the end near the first opening 106 in the third direction. The limiting points 206 are used to prevent the inner part 2 from disengaging from the outer part 1 in the direction toward the second opening 107. The third direction is perpendicular to the first direction and the second direction.

[0078] Understandably, in order to prevent the inner part 2 from detaching from the first opening 106 relative to the outer part 1 in the direction toward the second opening 107 under the action of the elastic member 3, this embodiment provides two limiting points 206 on the right end of the inner part 2 and on both sides in the third direction. These two limiting points 206 are protruding structures. After the inner part 2 is assembled, the limiting points 206 can prevent the outer part 1 from retracting.

[0079] In one possible implementation, the outer component 1 has curved surfaces on both sides in the third direction to facilitate gripping during use.

[0080] Understandably, in this embodiment, in order to make the cord buckle more ergonomic, more convenient and less strenuous to use, and easier for the user to hold, the outer part 1 in this embodiment is set with smooth arc surfaces on both sides in the third direction. This not only improves the grip but also reduces the risk of the cord buckle slipping out of the hand.

[0081] In the first embodiment, an elastic wall 101 is provided on the upper side of the outer component 1. The hook 102 of the elastic wall 101 is located at the left end of the outer component 1. The webbing connection part 201 and the rope hole 202 are both located on the right side of the inner component 2, and the locking part 204 is located at the right end. Under the action of the elastic force of the elastic element 3, the inner component 2 can have a certain amount of movement space along the Y-axis in the cavity 103 of the outer component 1, thereby affecting the distance between the rope clamping point and the distance between the rope pressing surface 105 and the rope hole 202, thus achieving the effect of clamping the rope 4. The specific principle is as follows: Figure 13 As shown; the rope buckle assembly process in this embodiment is as follows: Figure 11 As shown, first place the elastic element 3 into the elastic element placement groove 203 of the inner part 2, and then... Figure 10The assembly shown is inserted into the cavity of the outer part 1 along the Y-axis direction, so that the head of the inner part 2 protrudes to a certain extent on the right side. The limiting point 206 can hold the outer part 1 to prevent it from retracting, thus completing the assembly.

[0082] Furthermore, the usage process of the first embodiment is as follows: Figure 12 As shown, when the user presses the elastic wall 101 with their finger, the outer part 1 is pulled in the opposite direction of the first direction (this process compresses the elastic part 3). The inner part 2 is fixed in place by the webbing 5. At this time, the hook 102 will slide along the guide surface 205 until it hooks onto the inclined surface of the locking part 204, as shown. Figure 12 As shown in the second step, the angle design of the inclined surface of the locking part 204 and the hook foot 102 allows the inclined surface of the locking part 204 to abut against the hook foot 102 under the action of the spring force, preventing the elastic wall 101 from returning to its original position (the resisting force is greater than the force of the elastic wall 101 rebounding and returning to its original position). At this time, it is not necessary to continuously press the rope buckle by hand, as it is in a continuously relaxed state. The user can freely adjust the retraction of the elastic rope to achieve the purpose of relaxation adjustment. It achieves continuous relaxation with a single press; when it is necessary to tighten the rope buckle, as... Figure 12 As shown in the third step, pull rope 4 in the direction of the arrow. Since the upper end of rope 4 is fixed, the entire rope 4 pulls the outer part 1 to the left. At this time, the friction between the inclined surface of the locking part 204 and the hook foot 102 gradually decreases or even the inclined surface of the locking part 204 separates from the hook foot 102 and disengages. Under the action of its own elastic force, the elastic wall 101 drives the hook foot to spring back and reset. At this time, it is no longer constrained. The spring compression force is released, and the rope 4 is tightened again. At this time, you can continue to pull and tighten the rope 4 (just like a traditional rope buckle) to achieve the effect of tightening with one pull.

[0083] In another embodiment, the outer component 1 is provided with elastic walls 101 on both sides in the third direction, and the inner component 2 is provided with a locking part 204 that cooperates with the elastic walls 101 in the third direction.
