[0002] Cord locks are common in everyday life, often used on clothing such as sportswear and windbreakers. To adjust the size of hats, sleeves, and hems, traditional cord locks are constructed from two or more components assembled via springs. The springs' deformation provides elastic force, keeping the lock sliding up and down, thereby adjusting the tightness of the cord. However, since cord locks are assembled, collisions with the inner wall of a washing machine can cause the components to separate, making them susceptible to loss and product damage. Furthermore, since cord locks are modular, they require multiple components, making them difficult to manufacture and costly.

[0003] Therefore, how to reduce the production cost and difficulty of the rope adjustment buckle is a technical problem that those skilled in the art currently need to solve. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positions or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limitations of the present invention.

[0033] The utility model aims to provide a rope adjusting buckle, which can reduce the production cost and difficulty of the rope adjusting buckle.

[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. The first direction, the second direction and the third direction are perpendicular to each other.

[0035] To achieve the above objectives, the present invention provides the following technical solutions:

[0036] See also Figures 1 to 6 , this embodiment provides a rope adjustment buckle, comprising: a base body 100 and a pressing elastic arm 200; the base body 100 includes a first end 110 and a second end 120, the first end 110 and the second end 120 are respectively provided with a first hole 111 and a second hole 121 extending toward each other; the pressing elastic arm 200 is connected to the second end 120 and is located between the first end 110 and the second end 120, and a gap is left between the pressing elastic arm 200 and the first end 110, and a connecting hole 210 is provided in the middle of the pressing elastic arm 200 for connecting the first hole 111 and the second hole 121, the axis of the connecting hole 210 and the axis of the first hole 111 are radially offset to clamp the rope passed through the connecting hole 210, the first hole 111 and the second hole 121, and the end of the pressing elastic arm 200 close to the first end 110 can move so that the connecting hole 210 connects the first hole 111 and the second hole 121.

[0037] Specifically, if Figure 1 As shown, the two ends of the base body 100 in the first direction are respectively a first end 110 and a second end 120, wherein the first end 110 is the front end of the adjusting buckle, and the second end 120 is the rear end of the adjusting buckle. When the rope is passed into the adjusting buckle, it will be passed through the first end 110; and a through-type first hole 111 and a second hole 121 are respectively provided in the middle of the first end 110 and the second end 120, and the first hole 111 and the second hole 121 extend relative to each other, that is, the internal channels of the two are connected to each other. In this embodiment, the axes of the first hole 111 and the second hole 121 are parallel to each other and are both in a vertical plane passing through their axes.

[0038] At the same time, a pressing elastic arm 200 is provided on the base body 100, and the pressing elastic arm 200 is only connected to the top of the second end 120, so that the pressing elastic arm 200 forms a cantilever structure. Correspondingly, a gap is left between the other end of the pressing elastic arm 200 and the first end 110; and a connecting hole 210 is provided through the middle of the pressing elastic arm 200. In this embodiment, the connecting hole 210 also extends along the first direction, but the channel of the connecting hole 210 is dislocated in the height direction with the channel formed by the first hole 111, that is, dislocated in the second direction, as shown in FIG. Figure 3 and Figure 4As shown, in this way, the misaligned connecting hole 210 and the first hole 111 will generate a shear force on the rope passing through them, and the shear force will clamp the rope. When the rope needs to move, an external force can be applied to the free end of the pressing elastic arm 200 to move it downward, so that the end of the connecting hole 210 is aligned with the hole opening of the first hole 111, thereby connecting the first hole 111 and the second hole 121. In this way, the rope can move smoothly and effortlessly in the adjustment buckle.

[0039] When the rope adjustment buckle provided by the present invention is in use, the rope can pass through the first hole 111, the connecting hole 210 and the second hole 121 in sequence. However, due to the misalignment of the connecting hole 210 and the first hole 111, when no external force acts on the pressing elastic arm 200, the rope will be clamped in the adjustment buckle. When an external force is applied to the pressing elastic arm 200, its end interface close to the first end 110 will move downward and will be aligned and connected with the first hole 111. At this time, the rope can move smoothly in the adjustment buckle. With such a setting, the adjustment buckle provided by this embodiment has a simple appearance and structure, no built-in spring, and is not easy to separate and damage even if it is subjected to external force.

[0040] In this embodiment, the pressing elastic arm 200 includes an upper top wall 220 and a lower side wall 230 connected to each other. The upper top wall 220 is connected to the second end 120 , and a clearance gap 240 is left between the lower side wall 230 and the second end 120 .

[0041] Specific as Figure 3 As shown, the pressing elastic arm 200 is a cylindrical structure as a whole, including an upper top wall 220 at the top in the second direction and a lower side wall 230 at the lowest side, the upper top wall 220 is the highest point of the communicating hole 210, and the lower side wall 230 is the lowest point of the communicating hole 210; in this embodiment, a certain gap is left between the free end of the pressing elastic arm 200 and the first end 110, and this gap is reserved for the pressing stroke of the pressing elastic arm 200. It can be understood that when the free end of the pressing elastic arm 200 is pressed downward, the lower side wall 230 of the pressing elastic arm 200 will be squeezed with the second end 120. Therefore, in this embodiment, the pressing The lower side wall 230 of the elastic arm 200 is not connected to the second end 120, and a certain clearance gap 240 is provided between the two. In this way, when the elastic arm 200 is pressed down, its free end will move toward the first end 110 to the reserved gap. At the same time, the lower side wall 230 will also be squeezed into the clearance gap 240 to prevent the pressing elastic arm 200 from breaking from the second end 120 due to force. In addition, the setting of the clearance gap 240 also makes pressing the pressing elastic arm 200 more labor-saving and convenient; of course, the width of the clearance gap 240 can be set according to actual conditions, and this article does not make a specific limitation.

[0042] Preferably, the lower side wall 230 is located between the highest point and the lowest point of the first hole 111 in the radial direction.

[0043] In this embodiment, the connecting hole 210 intersects with the projection of the first hole 111 on a plane perpendicular to the first direction, rather than being separated or tangent to each other. Figure 4 As shown, the lower side wall 230 is located between the highest point and the lowest point of the first hole 111 in the radial direction, that is, the position in the second direction. This arrangement is to ensure that when the pressing spring arm 200 is not pressed by external force, the connecting hole 210 can be in a misaligned state with the first hole 111, so as to generate a shear force to constrain the rope passing through. However, it is also necessary to ensure that the misalignment distance between the connecting hole 210 and the first hole 111 is within the pressing stroke range of the free end of the pressing spring arm 200, that is, after the pressing spring arm 200 is pressed downward, the connecting hole 210 can be aligned and connected with the first hole 111; moreover, when the misalignment distance between the connecting hole 210 and the first hole 111 is too long, each time the force applied to the pressing spring arm 200 is withdrawn, the pressing spring arm moves upward for too long, which will cause a pulling force on the rope, so that the rope will be pulled by this force, making the whole process not smooth and causing greater wear on the rope.

[0044] Of course, the offset distance between the communicating hole 210 and the first hole 111 can be adjusted according to actual conditions, and is not specifically limited herein.

[0045] Preferably, the axial projection of the communicating hole 210 is located inside the axial projection of the second hole 121 .

[0046] It can be understood that the axial projection of the connecting hole 210 and the second hole 121 is the projection in the first direction, and the projection of the connecting hole 210 is inside the second hole 121, that is, the cross-section of the connecting hole 210 is entirely included in the second hole 121. This arrangement is to ensure that the rope can move smoothly in the adjustment buckle after the first hole 111 and the connecting hole 210 are aligned; in other words, this arrangement ensures that the rope is only subjected to the shear force generated by the misalignment of the connecting hole 210 and the first hole 111 inside the adjustment buckle, so that after pressing the elastic arm 200 and releasing the shear force there, the rope can move smoothly in the adjustment buckle without being hindered by the second hole 121 again.

[0047] Preferably, a bending groove 250 is provided on the outer side of the upper top wall 220 to control the difficulty of pressing the elastic arm 200 downward.

[0048] It is understandable that in order to save the force required to press the elastic arm 200, a bending groove 250 extending along the third direction is provided on the outer side of the connection between the upper top wall 220 and the second end 120, as shown in FIG. Figure 1 and Figure 2 As shown, by setting the depth and width of the groove, the force required to press the elastic arm 200 is changed, thereby controlling the difficulty of pressing the elastic arm 200 downward.

[0049] Preferably, both sides of the base body 100 are provided with belt holes 130 to facilitate the installation of the base body 100 .

[0050] In this embodiment, strap holes 130 are also provided on both sides of the base body 100. The adjustment buckle provided in this article can be fixed to the clothes through the strap holes 130 on both sides. The two sides of the base body 100 mentioned here refer to the two sides of the base body 100 in the third direction. In this embodiment, the strap holes 130 are strip-shaped square holes.

[0051] Preferably, the first end 110 and the second end 120 are both arched, the upper top wall 220 is provided with a pressing platform 260 , and the height of the pressing platform 260 is greater than the height of the first end 110 .

[0052] Specific as Figure 4 and Figure 5 As shown, in this embodiment, the cross-section of the first end 110 and the second end 120 perpendicular to the first direction is an arched structure, and a pressing platform 260 is provided at the top of the pressing spring arm 200. The pressing platform 260 is parallel to the horizontal plane, which is convenient for the user to apply external force to the pressing spring arm 200. Furthermore, in order to improve the convenience of using the adjustment buckle, the height of the pressing platform 260 in the second direction is higher than the first end 110 and the second end 120, that is, the pressing platform 260 protrudes from the first end 110 and the second end 120, so that the user can easily press the pressing spring arm 200.

[0053] Preferably, the first hole 111 has the same diameter as the connecting hole 210, and the second hole 121 is a waist-shaped hole for the rope to move.

[0054] Specifically, if Figure 4 and Figure 5 As shown, in order to ensure the smooth movement of the rope passed through the adjustment buckle, in this embodiment, the first hole 111 and the connecting hole 210 have the same diameter, and in order to ensure that the second hole 121 does not affect the movement of the rope, the second hole 121 is set to a waist-shaped hole, the long axis direction of the waist-shaped hole is parallel to the second direction, and its width is the same as the diameter of the first hole 111. Such a setting can prevent the rope from swinging left and right along the third direction in the second hole 121, and since it leaves sufficient reserved space in the second direction, it will not hinder the movement of the rope.

[0055] Preferably, the first end 110 is provided with two parallel first holes 111 , and the pressing elastic arm 200 is provided with two parallel communicating holes 210 in the middle.

[0056] In another embodiment, in order to adapt to more application scenarios, the width of the first end 110, the second end 120 and the pressing elastic arm 200 in the third direction can be increased, and two or more first holes 111 are set in parallel at the first end 110, and correspondingly, the same number of connecting holes 210 need to be set in the middle of the pressing elastic arm 200, and the last second holes 121 can be connected to each other in the third direction as long as it does not affect the movement of the rope.

[0057] Preferably, the base body 100 and the pressing elastic arm 200 are made of elastic material, and the base body 100 and the pressing elastic arm 200 are an integrated structure.

[0058] It should be noted that the adjustment buckle in this embodiment is integrally formed by using elastic material. The selection of elastic material can ensure that the elastic arm 200 can automatically recover after each pressing, and the integrated structural setting can avoid assembly during the production process of the adjustment buckle, thereby reducing the production cost and difficulty. In addition, the adjustment buckle has an overall integrated structure without a built-in spring. Even if the adjustment buckle is impacted by a certain external force, it is not easily damaged, thereby extending its service life.

[0059] 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.

[0060] 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.

[0061] The above is a detailed introduction to the embodiments provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be noted that, for those skilled in the art, without departing from the principles of the present invention, various improvements and modifications may be made to the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
