Abstract
Description
Technical Field
[0001] This utility model relates to the field of rope stopper technology, and in particular to a rope stopper. Background Technology
[0002] In daily life, clothing, shoes, hats, backpacks, and other items often require the use of cord locks. Cord locks serve to secure and adjust cords to tighten the loop. Generally, cord locks work by pressing on a locking mechanism with an elastic component, allowing the cord to slide smoothly through the channel. The internal elastic component then compresses the cord, creating a locking state. Because the direction of the compressive force exerted by the metal elastic component on the cord lock is the same as the direction of the hand pressing, the component can easily spring out and cause injury or be lost.
[0003] Existing technology discloses a rope buckle that improves the user experience by changing the direction of the squeeze and using a two-end pressing method. However, adjusting the tightness of the rope requires two hands, which is inconvenient. Therefore, a rope buckle stopper is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a rope buckle that solves the technical problem that existing rope buckles use a two-end pressing method, requiring two hands to operate and tighten or loosen the rope, which is inconvenient.
[0005] To achieve the above objectives, this utility model provides a rope buckle, comprising: an outer component, the top surface of which is provided with an inner cavity with a top opening, a first end of which is provided with a first connecting structure, a second end of which is provided with a first rope hole, and the first end of which is provided with a rope hole groove for threading a rope.
[0006] An inner component is disposed within the inner cavity. A second connecting structure is provided at the first end of the inner component. The second connecting structure cooperates with the first connecting structure to allow the inner component to rotate around the second connecting structure. A second rope hole is provided at the second end of the inner component. The second rope hole is aligned with the first rope hole to allow ropes to pass through simultaneously.
[0007] An elastic component is provided between the outer component and the inner component. The elastic force of the elastic component causes the second rope hole and the first rope hole to tend to be misaligned to secure the rope.
[0008] Preferably, one of the first connecting structure and the second connecting structure is an insertion part, and the other of the first connecting structure and the second connecting structure is a fixing frame having a slot adapted to the insertion part.
[0009] Preferably, the fixing frame has two limiting partitions symmetrically arranged on both sides of the slot. When the insertion part is inserted into the slot, the two limiting partitions abut against the side of the insertion part to form a limiting position.
[0010] Preferably, the first connecting structure is a slot, which is disposed through the end of the first end of the outer component, and the second connecting structure is an extension, which is disposed at the end of the first end of the inner component.
[0011] Preferably, the elastic component is a spring, and a limiting protrusion is provided on the bottom surface of the inner cavity, the limiting protrusion being inserted into the lower end of the elastic component.
[0012] Preferably, the bottom surface of the inner component is provided with an assembly slot, which engages with the second end of the elastic component.
[0013] Preferably, a limiting buckle is provided on the outer side of the second end of the inner component, and a limiting hole is provided on the inner side of the second end of the outer component, with the limiting buckle slidably connected to the limiting hole.

[0015] Preferably, the limiting hole is disposed between the two first rope holes, and the limiting buckle is disposed between the two second rope holes.
[0016] Preferably, two rope limiting grooves for threading the rope are symmetrically arranged on both sides of the inner cavity.
[0017] Compared to the aforementioned background technology, the rope buckle provided by this utility model has the following beneficial effects: the second connecting structure cooperates with the first connecting structure to allow the inner part to rotate around the second connecting structure. When the inner part is pressed and rotated at a certain angle relative to the outer part, so that the second rope hole is aligned with the first rope hole, the rope can pass through the first rope hole and the corresponding second rope hole simultaneously, and the rope can slide freely in the first rope hole and the corresponding second rope hole. After the inner part is released, under the support of the elastic component, the second rope hole and the first rope hole tend to be misaligned. At this time, the inner part and the outer part cooperate to lock the rope. The entire operation can be completed by one hand to tighten or loosen the rope, which is simple and convenient to use.

Detailed Implementation
[0035] 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.
[0036] 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.
[0037] like Figure 1 , Figure 2 and Figure 3 As shown, to achieve the above objectives, this utility model provides a cord 4 stop buckle, comprising: an outer component 1, an inner component 2, and an elastic component 3. The outer component 1 has a top-opening inner cavity 101 on its top surface, which accommodates the inner component 2. A first connecting structure 102 is provided at the right end of the outer component 1. Specifically, the inner component 2 is disposed within the inner cavity 101, and a second connecting structure 201 is provided at the right end of the inner component 2. The second connecting structure 201 cooperates with the first connecting structure 102 to allow the inner component 2 to rotate around the second connecting structure 201 at a certain angle.
[0038] like Figure 4 and Figure 5As shown, the left end of the outer component 1 is provided with two first rope holes 103, each for threading a rope 4. The left end of the inner component 2 is provided with two second rope holes 202, each corresponding to one first rope hole 103. When the second rope holes 202 and the first rope holes 103 are aligned, the rope 4 can pass through simultaneously. In addition, the right end of the inner component 2 is open to facilitate the passage of the rope 4. When the second rope holes 202 and the first rope holes 103 are aligned, the rope 4 can pass through both the first rope hole 103 and the corresponding second rope hole 202 simultaneously, and the rope 4 can slide freely within the first rope hole 103 and the corresponding second rope hole 202. In addition, two cord perforation slots 104 are provided at the right end of the outer part 1. The two cord perforation slots 104 pass through the right end of the outer part 1 and are used to thread the cord 4. The two cord perforation slots 104 can be connected or not connected to each other. The main purpose is to thread the cord 4 through the two first cord holes 103. Later, the other end of the cord 4 is fixed to the fabric so that the cord 4 has a fixed tension point and is easy to pull.
[0039] like Figure 6 , Figure 7 and Figure 8 As shown, an elastic component is provided between the outer and inner components. The upper end of the elastic component 3 is connected to the left end of the inner component 2, and the lower end of the elastic component 3 is connected to the left end of the outer component 1. The elastic component can provide a certain support for the inner and outer components. The elastic force of the elastic component causes the second rope hole and the first rope hole to tend to misalign with each other to lock the rope. Specifically, the upper end of the elastic component 3 is connected to the bottom surface of the left end of the inner component 2, and the lower end of the elastic component 3 is connected to the bottom surface of the left end of the inner cavity 101. When the inner component 2 is not pressed, the supporting force provided by the elastic component 3 between the inner component 2 and the outer component 1 causes the second rope hole 202 and the first rope hole 103 to tend to misalign with each other under the support of the elastic component 3. At this time, the inner component 2 and the outer component 1 cooperate to lock the rope 4. When the inner part 2 is pressed and rotated at a certain angle relative to the outer part 1, so that the second rope hole 202 is aligned with the first rope hole 103, the rope 4 can slide freely in the first rope hole 103 and the corresponding second rope hole 202. The entire operation can be completed by one hand to tighten or loosen the rope 4, which is simple and convenient to use.
[0040] On the other hand, the inner component 2 and the outer component 1 can control the tightness of the rope 4 through the first connecting structure 102, the second connecting structure 201 and the elastic component 3. The overall buckle structure of the rope 4 is simple, making it easier to assemble. It does not have a complicated structural design and its quality is more stable during use.
[0041] like Figure 9As shown, in some embodiments of this utility model, one of the first connecting structure 102 and the second connecting structure 201 is an insertion part, and the other of the first connecting structure 102 and the second connecting structure 201 is a fixing frame. The fixing frame has a slot adapted to the insertion part. The insertion part is an L-shaped limiting shaft, and the fixing frame is an n-type fixing frame, or it can be a C-type fixing frame. Optionally, the first connecting structure 102 is an insertion part, and the second connecting structure 201 is a fixing frame. Through the cooperation of the insertion part and the fixing frame, while ensuring that the first connecting structure 102 can rotate smoothly relative to the second connecting structure 201, it also facilitates the assembly and disassembly of the first connecting structure 102 and the second connecting structure 201. Moreover, after the first connecting structure 102 and the second connecting structure 201 are connected, the structure is more stable. Of course, as... Figure 14 As shown, in the third embodiment of this utility model, the second connecting structure 201 can also be designed as an insertion part, and the first connecting structure 102 can be a fixing frame.
[0042] like Figure 4 As shown, optionally, the free end of the insertion part is provided with an arc-shaped groove. When the insertion part enters the arc-shaped groove 205, the inner side of the arc-shaped groove 205 fits against the outer peripheral side of the insertion part, effectively ensuring the connection stability between the insertion part and the fixing frame.
[0043] like Figure 3 and Figure 10 As shown, in some embodiments of this utility model, the fixing frame has two symmetrical limiting partitions 107 on both sides of the corresponding slot. When the insertion part is inserted into the slot, the sides of the two limiting partitions 107 respectively abut against the two sides of the insertion part to limit the sides of the insertion part, thereby making the fixing frame rotate stably relative to the insertion part without twisting or other unstable phenomena. In addition, when the second connecting structure 201 is the insertion part and the first connecting structure 102 is the fixing frame, the limiting partitions 107 can initially separate the ropes 4 passing through the two first rope holes 103. The ropes 4 passing through the two first rope holes 103 do not interfere with each other when sliding, effectively avoiding mutual friction between the ropes 4 passing through the two first rope holes 103 and improving the service life of the ropes 4.
[0044] like Figure 11 , 12 As shown in Figure 13, in the second embodiment of this utility model, the first connecting structure 102 is a slot, which is disposed through the left end of the outer part 1. The second connecting structure 201 is an extension, which is integrally disposed at the end of the first end of the inner part 2. That is, the first connecting structure 102 and the second connecting structure 201 are connected together by a plug-in method, which makes the overall structure simpler and the quality more stable during use. Optionally, the extension is a rectangular injection molded part. In this case, when the inner part 2 is molded, there is no need to reserve a demolding hole at the bottom, making the mold opening of the inner part 2 more convenient.
[0045] It should be noted that when the two rope perforation grooves 104 are not connected to each other, the slot is set between the two rope perforation grooves 104. When the two rope perforation grooves 104 are connected, the two rope perforation grooves 104 serve as slots.
[0046] like Figure 9 As shown, in some embodiments of this utility model, the elastic component 3 is a spring, and a limiting protrusion 106 is provided on the bottom surface of the inner cavity 101. The limiting protrusion 106 passes through the lower end of the elastic component 3. The limiting protrusion 106 can limit the lower end of the elastic component 3, preventing the elastic component 3 from shifting within the inner cavity 101, improving the stability of the inner component 2 relative to the outer component 1 when rotating, and ensuring that the elastic component 3 can always provide a stable supporting force between the inner component 2 and the outer component 1 when the inner component 2 is not pressed, so that the inner component 2 and the outer component 1 can cooperate to stably lock the rope 4. Optionally, the limiting protrusion 106 is cylindrical in shape, and the outer peripheral side of the limiting protrusion 106 abuts against the circumferential inner side of the lower end of the elastic component 3 to further lock and connect the lower end of the elastic component 3. Of course, the limiting protrusion 106 can also be prism or other shapes. The structure of the limiting protrusion 106 is not specifically limited, the purpose of which is to ensure that the elastic component 3 will not shift within the inner cavity 101.
[0047] Of course, the elastic component 3 can also be a plastic spring-loaded top sheet (not shown in the figure). The plastic spring-loaded top sheet can also provide a stable supporting force between the inner part 2 and the outer part 1 through its own elastic expansion and contraction.
[0048] In some embodiments of this utility model, the bottom surface of the inner part 2 is provided with a mounting groove 203, which engages with the upper end of the elastic component 3. By engaging the upper end of the elastic component 3 with the mounting groove 203, the upper end of the elastic component 3 can be limited, preventing the elastic component 3 from shifting relative to the bottom surface of the inner part 2. This further improves the stability of the inner part 2 when rotating relative to the outer part 1, ensuring that the elastic component 3 can always provide a stable supporting force between the inner part 2 and the outer part 1 when the inner part 2 is not pressed, so that the inner part 2 and the outer part 1 can cooperate to stably hold the rope 4.
[0049] Optionally, the assembly slot 203 is cylindrical in shape. When the inner part 2 is placed horizontally and the elastic component 3 is placed vertically, the cross-section of the assembly slot 203 in the vertical direction is larger than the cross-section of the elastic component 3 in the vertical direction, so as to ensure that the upper end of the elastic component 3 has a certain amount of room for movement in the assembly slot 203, so as to ensure the normal expansion, contraction and bending of the elastic component 3.
[0050] like Figure 6As shown, in some embodiments of this utility model, a limiting buckle 204 is provided on the outer side of the left end of the inner part 2, and a limiting hole 105 is provided on the inner side of the left end of the outer part 1. The limiting buckle 204 is slidably connected to the limiting hole 105. Through the sliding engagement of the limiting buckle 204 and the limiting hole 105, the movement path of the inner part 2 can be limited and corrected when the inner part 2 rotates relative to the outer part 1, ensuring the stability of the inner part 2 when rotating relative to the outer part 1. Moreover, through the sliding engagement of the limiting buckle 204 and the limiting hole 105, the phenomenon of the inner part 2 easily detaching from the outer part 1 will not occur.
[0051] It should be noted that when the bottom surface of the limiting buckle 204 abuts against the bottom surface of the limiting groove, the inner part 2 is pressed to the limit position relative to the outer part 1, the first rope hole 103 and the corresponding second rope hole 202 are aligned, and the rope 4 can slide freely in the first rope hole 103 and the corresponding second rope hole 202; when the top surface of the limiting buckle 204 abuts against the upper side of the limiting groove, the second rope hole 202 and the first rope hole 103 are misaligned, and the inner part 2, under the elastic force of the elastic component 3, cooperates with the outer part 1 to squeeze the rope 4, so that the rope 4 is stably locked.
[0052] like Figure 15 As shown, it should be noted that when the rope 4 buckle is placed horizontally and the second rope hole 202 is aligned with the first rope hole 103, the inner wall of the outer part 1 on the horizontal plane and the inner wall of the inner part 2 on the horizontal plane are smoothly connected to ensure that the connection between the outer part 1 and the inner part 2 does not interfere with the rope threading, and at the same time, it does not affect the sliding of the rope 4.
[0053] In some embodiments of this utility model, the limiting buckle 204 is made of an elastic deformable material, and the two sides of the limiting buckle 204 are respectively attached to one side of the limiting hole 105. Through the interference fit between the limiting buckle 204 and the limiting hole 105, when the inner part 2 rotates relative to the outer part 1, there will be a certain frictional force between the limiting buckle 204 and the limiting groove, so that the limiting buckle 204 will not easily shift or deviate in the limiting groove, thereby providing a certain support force for the inner part 2, ensuring that the inner part 2 will not shake relative to the outer part 1, and improving the overall stability of the rope 4 buckle.
[0054] Optionally, the limit buckle 204 is made of rubber. The rubber material has the advantages of good elastic deformation ability, large coefficient of friction and better wear resistance, which ensures that the limit buckle 204 and the limit groove can always be stably matched.
[0055] In some embodiments of this utility model, the limiting hole 105 is disposed between two first rope holes 103, and the limiting buckle 204 is disposed between two second rope holes 202. The rope 4 passing through the two first rope holes 103 and the limiting buckle 204 form a three-channel diversion, which do not interfere with each other, thus preventing the rope 4 from contacting the limiting buckle 204 when sliding, and improving the service life of the rope 4.
[0056] Optionally, two rope limiting grooves 108 for threading ropes are symmetrically arranged on both sides of the inner cavity 101. The rope limiting grooves 108 limit the ropes 4 threaded through the two first rope holes 103, so that the ropes 4 do not come into contact with the inner part 2 and other structural components outside the rope limiting grooves 108, thereby further improving the service life of the ropes 4.
[0057] Optionally, the top surface of the inner part 2 can be set as an arc surface. The arc surface design is more ergonomic and easier to press with the thumb, thereby improving the comfort of using the cord 4 buckle.
[0058] The working principle of this utility model is as follows: The first connecting structure 102 is rotatably connected to the second connecting structure 201, completing the initial alignment and fixation of the inner part 2 and the outer part 1. The upper end of the elastic component 3 is connected to the left end of the inner part 2, and the lower end of the elastic component 3 is connected to the left end of the inner part 2. The inner part 2 is pressed to enter the inner cavity 101 until the limiting buckle 204 enters the limiting hole 105, and the inner part 2 is confined in the inner cavity 101. In the initial state, when the inner part 2 is not pressed, the elastic component 3 provides a certain supporting force between the inner part 2 and the outer part 1, so that the second rope hole 202 and the first rope hole 103 tend to be misaligned. At this time, the inner part 2 and the outer part 1 cooperate to hold the rope 4. When the inner part 2 is pressed and rotated at a certain angle relative to the outer part 1, the first rope hole 103 and the corresponding second rope hole 202 are aligned, and the rope 4 can slide freely.
[0059] In summary, the inner part 2 can rotate around the second connecting structure 201 by cooperating with the first connecting structure 102. When the inner part 2 is pressed and rotated at a certain angle relative to the outer part 1, the rope 4 can slide freely in the first rope hole 103 and the corresponding second rope hole 202. After the inner part 2 is released, under the support of the elastic component 3, the inner part 2 and the outer part 1 cooperate to lock the rope 4. The entire operation can be completed by one hand to tighten or loosen the rope 4, which is simple and convenient to use.
[0060] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0061] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
