Description

Technical Field

[0001] The utility model relates to the technical field of buckle manufacturing, in particular to a rope buckle. Background Art

[0002] Nowadays, cord stops are very common in various applications. Different types of cord stops have different fastening methods and are widely used in products such as shoes, bags, and clothing. Generally, cord stops allow the cord to pass through and slide along the surface of the cord to fix or adjust the tension.

[0003] The common rope buckles on the market are usually composed of a base, a button and a spring. There is a accommodating groove inside the base, and the two side walls are provided with through holes that penetrate to the outside. The column of the button is located in the accommodating groove and is provided with a through hole, and the spring is positioned between the base and the button. The rope can pass through the two through holes of the base and the through hole of the button. The elastic force of the spring pushes the button upward, so that the through hole of the button is misaligned with the through hole of the base, thereby clamping the rope and fixing the position. When the user needs to adjust the rope, press the button to compress and deform the spring. At this time, the through hole of the button is aligned with the through hole of the base, and the user can pull the rope to adjust the tightness. After releasing the button, the spring resets the button, so that the through hole is misaligned again, thereby re-clamping the rope and fixing the position. The structure of this rope buckle consists of a base, a button and a spring. Not only does it have many components and a complex structure, but it is also inconvenient to produce and assemble.

[0004] Therefore, how to provide a rope stopper with a simple structure and easy and labor-saving operation is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0005] The utility model aims to provide a rope buckle which has a simple structure and is easy and labor-saving to operate.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A rope buckle comprises: an elastic buckle body for accommodating a rope, a slot penetrating along a first direction is arranged in the buckle body, first protrusions are arranged on both inner walls of the slot in a second direction, second protrusions are arranged on both inner walls of the slot in a third direction, the second protrusion on one side extends toward the second protrusion on the other side to divide the slot into a first slot and a second slot, and the openings of the first slot and the second slot are both smaller than the diameter of the rope.

[0008] Preferably, first arc-shaped grooves are symmetrically provided on the outer walls of both sides of the buckle body in the second direction.

[0009] Preferably, the size of the first protrusion is smaller than the size of the second protrusion.

[0010] Preferably, the wall thickness of both sides of the buckle body in the second direction is greater than the wall thickness of both sides of the buckle body in the third direction.

[0011] Preferably, both outer walls of the buckle body in the third direction are convex arc surfaces.

[0012] Preferably, both ends of the buckle body in the first direction are provided with a second arc-shaped groove.

[0013] Preferably, the buckle body is integrally formed by injection molding.

[0014] Preferably, the buckle body material is TPU material.

[0015] Preferably, a handle is further included, wherein the handle is provided with two through holes for the rope to pass through, and a side of the handle close to the buckle body is provided with an arc-shaped protrusion adapted to the second arc-shaped groove.

[0016] Preferably, the two second protrusions extend toward each other and intersect to form a bending portion separating the first clamping slot and the second clamping slot.

[0017] Compared with the above-mentioned background technology, the utility model provides a rope buckle, including: a buckle body for accommodating a rope and having elasticity, a slot along a first direction is provided in the buckle body, first protrusions are provided on both side inner walls of the slot in a second direction, second protrusions are provided on both side inner walls of the slot in a third direction, the second protrusion on one side extends toward the second protrusion on the other side to divide the slot into a first slot and a second slot, and the openings of the first slot and the second slot are both smaller than the diameter of the rope.

[0018] Specifically, the rope passes through the first card slot and the second card slot in the buckle body, and because the first protrusion and the second protrusion jointly clamp the rope, and because the diameters of the first card slot and the second card slot are smaller than the diameter of the rope, the rope can be prevented from slipping out of the card slot in the case of non-human force extrusion, and the rope can also pass through the card slot when subjected to a large tension. When the two outer walls of the buckle body provided with the first protrusion are squeezed by human force, the first protrusion is squeezed inwardly, and because the buckle body has a certain elasticity, the second protrusions will move away from each other, so that the diameters of the first card slot and the second card slot are expanded, so that the rope can be easily extended into or out of the card slot. In this way, the clamping and sliding of the rope can be very convenient and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0033] The utility model aims to provide a rope buckle which has a simple structure and is easy and labor-saving to operate.

[0034] It should be noted that, in this embodiment, the X direction in the accompanying drawings is defined as the first direction, the Y direction is defined as the second direction, and the Z direction is defined as the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0035] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0036] See also Figures 1 to 8 The present embodiment provides a rope buckle, comprising: a buckle body 02 for accommodating a rope 01 and having elasticity, a slot along a first direction being arranged in the buckle body 02, first protrusions 03 being arranged on both inner walls on both sides of the slot in a second direction, second protrusions 04 being arranged on both inner walls on both sides of the slot in a third direction, the second protrusion 04 on one side extending toward the second protrusion 04 on the other side so as to divide the slot into a first slot 05 and a second slot 05, and the openings of the first slot 05 and the second slot 05 are both smaller than the diameter of the rope 01.

[0037] Specifically, the buckle body 02 allows the rope 01 to pass through and slide along the direction in which the rope 01 extends. Figure 4 In the direction of the arrow in the middle, the tightness of the rope 01 is fixed or adjusted, wherein the rope 01 passes through the through-type card slot set in the middle of the buckle body 02, and the card slot is specifically along Figure 1 The card slot is provided with a first protrusion 03 and a second protrusion 04 for clamping the rope 01, and the first protrusion 03 is symmetrically arranged in the second direction at both ends of the inner wall of the buckle body 02, that is, Figure 2 and Figure 3 The left and right inner walls in the horizontal direction, at the same time, the second protrusion 04 is arranged on the inner walls of the buckle body 02 on both sides in the third direction, that is, Figure 2 and Figure 3The two inner walls in the vertical direction, the two second protrusions 04 extend toward each other, and cooperate with the first protrusion 03 to divide the slot in the buckle body 02 into two left and right parts, namely the first slot 05 and the second slot 05. The first slot 05 and the second slot 05 are symmetrically arranged, and the rope 01 can pass through both of them. It should be noted that the opening size of the first slot 05 and the second slot 05 is smaller than the diameter of the rope 01 when no external force is applied to the buckle body 02. In this way, when the rope 01 is pulled by non-human force, the rope 01 will be firmly connected to the first slot 05 and the second slot 05; in the present embodiment, the second protrusions 04 are close to each other but not connected together, and a gap is left between the two, that is, when an external force is applied When the outer walls of both sides of the buckle body 02 are provided with the first protrusion 03, the buckle body 02 will be squeezed, and the upper wall and the lower wall of the buckle body 02 will bend. However, since the second protrusions 04 are both protruding inward, the upper wall and the lower wall of the buckle body 02 will bend outward, so that the second protrusions 04 will move away from each other, as shown in Figure 6. In this way, the first protrusions 03 will approach each other, and the opening size of the first card slot 05 and the second card slot 05 formed by the first protrusion 03 and the second protrusion 04 will be expanded. At this time, it is very labor-saving and convenient to pull the rope 01 to adjust the tightness of the rope 01, and after the adjustment is completed, loosen the buckle body 02, and the buckle body 02 will return to its original state again, and lock the rope 01 passed through it again, as shown in Figure 6. Figure 5 It should be noted that the buckle body 02 in this embodiment is made of an elastic material during manufacturing.

[0038] That is to say, the rope 01 passes through the first card slot 05 and the second card slot 05 in the buckle body 02, and because the first protrusion 03 and the second protrusion 04 jointly clamp the rope 01, and because the diameters of the first card slot 05 and the second card slot 05 are smaller than the diameter of the rope 01, the rope 01 can be prevented from slipping out of the card slot in the case of non-human force squeezing, and the rope 01 can also pass through the card slot when it is subjected to a large tension. Figure 5 As shown, when the two outer walls of the first protrusion 03 of the buckle body 02 are squeezed manually, the first protrusion 03 is squeezed inwardly. At the same time, since the buckle body 02 has a certain elasticity, the second protrusions 04 will move away from each other, releasing the space in the middle, so that the diameters of the first slot 05 and the second slot 05 are expanded, so that the rope 01 can be easily extended into or out of the slot. Figure 6 As shown, Figure 6The direction of the middle arrow is the direction in which the buckle body 02 is deformed. Thus, the buckle body 02 in this embodiment is not provided with a complex structure such as a spring, and has a simple structure, a small size, and a light weight. Its production and assembly are very convenient and fast, which reduces the production cost of the rope 01 buckle, and it can also conveniently and labor-savingly complete the clamping and pulling of the rope 01.

[0039] In this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, first arc-shaped grooves 07 are symmetrically arranged on the outer walls on both sides of the buckle body 02 in the second direction. The two first arc-shaped grooves are more in line with the state of human body pressing. Such a setting can facilitate the pinching force of fingers, making the pressing area larger, making the pressing more comfortable and less labor-saving.

[0040] In addition, in this embodiment, the size of the first protrusion 03 is smaller than the size of the second protrusion 04. Figure 2 and Figure 3 As shown, the size can be specifically the size in the Y direction and the Z direction, that is, the volume of the first protrusion 03 should also be smaller than the volume of the second protrusion 04. With such a configuration, when an external force is applied to both sides of the buckle body 02 in the horizontal direction (Y direction), the second protrusions 04 can be moved away from each other, thereby releasing a larger middle space for the passage of the rope 01, and when the external force is withdrawn, the rope 01 can be firmly clamped; the size ratio of the first protrusion 03 and the second protrusion 04 can be adjusted according to the actual width of the buckle body 02 in the horizontal direction and the thickness in the vertical direction, as long as the purpose can be achieved.

[0041] It can be understood that the buckle body 02 will be subjected to horizontal force, and the positions where the buckle body 02 is deformed are mainly its upper wall and lower wall. Therefore, in this embodiment, in order to facilitate the deformation of the buckle body 02 when it is pinched and to facilitate operation, the thickness of the walls on both sides in the second direction is greater than the thickness of the walls on both sides in the third direction. In this way, the buckle body 02 can be deformed with less force, thereby adjusting the rope 01.

[0042] Furthermore, the outer walls on both sides of the buckle body 02 in the third direction are both set to convex arc surfaces 08, so that the convex arc surfaces 08 can guide the applied force to the up and down directions when the buckle body 02 is pinched, so that the upper wall and the lower wall of the buckle body 02 are bent outward, thereby releasing the space in the middle of the buckle body 02.

[0043] In addition, if Figure 4As shown, in the present embodiment, both ends of the buckle body 02 in the first direction are provided with a second arc-shaped groove 09. The provision of the second arc-shaped groove 09 firstly reduces the strength of the upper wall and the lower wall of the buckle body 02, making the operation of the buckle body 02 easier and more convenient. Secondly, by providing the second arc-shaped groove 09 at both ends of the buckle body 02 in the first direction, the card slots at both ends are opened outward, which is helpful for the insertion of the rope 01 and has better guidance and smoothness when sliding.

[0044] Of course, in this embodiment, in order to increase production efficiency, reduce the difficulty of manufacturing and reduce production costs, the buckle body 02 is integrally formed by injection molding. This arrangement can also improve the overall structural strength of the buckle body 02.

[0045] In this embodiment, the material of the buckle body 02 is specifically TPU (thermoplastic polyurethane elastomer) material, which is an elastomer that can be plasticized by heating and dissolved by solvents. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, oil resistance, and good processing performance.

[0046] In some embodiments, the rope 01 stopper also includes a handle 10, as shown in FIG. Figure 7 As shown, the handle 10 is provided with two through holes for the rope 01 to pass through, and the side of the handle 10 close to the buckle body 02 is provided with an arc-shaped protrusion adapted to the second arc-shaped groove 09. When the end of the rope 01 is adjusted to be close to the buckle body 02, the rope 01 can be prevented from passing through and detaching from the buckle body 02, and the rope 01 is pulled by the handle 10, making it easier to adjust the rope 01.

[0047] In another embodiment, the two second protrusions 04 extend toward each other and intersect each other, and the two second protrusions 04 form a bending portion separating the first card slot 05 and the second card slot 05. Figure 8 As shown, the thickness of the bent portion is relatively small. When no external force is applied to the buckle body 02, the bent portion will be in a bent state, and its left and right sides will support the rope 01. In the pinched state, the bent portion will be stretched accordingly, thereby weakening the clamping force on the rope 01. Its usage and effect are the same as the above-mentioned scheme.

[0048] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0049] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0050] The above is a detailed introduction to the embodiments provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
