[0035] The existing detachable double-hole cord buckle has a relatively complex structure, requires the product to be assembled from multiple parts, and is relatively large in size.

[0036] The following is a preferred embodiment of a detachable cord buckle provided by this utility model that can solve the above technical problems.

[0037] A preferred embodiment of this utility model provides a detachable rope buckle for adjusting the first and second rope straps. Please refer to... Figure 1 The detachable cord buckle includes a female buckle 11 and a male buckle 12.

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The female buckle 11 can adjust the first cord. The female buckle 11 is provided with a female receiving cavity 111, and the female receiving cavity 111 has a first female opening 1111. A limit ring 112 is provided inside the female receiving cavity 111. The male buckle 12 can adjust the second cord. The male buckle 12 is provided with a protrusion 121. The protrusion 121 can enter and exit the female receiving cavity 111 through the first female opening 1111. When the protrusion 121 is located in the female receiving cavity 111, the limit ring 112 is sleeved on the protrusion 121 to realize the detachable connection between the female buckle 11 and the male buckle 12.

[0039] This utility model's detachable cord buckle allows for easy assembly of the female buckle 11 and male buckle 12. When the female buckle 11 and male buckle 12 need to be combined, the protrusion 121 is forcefully inserted into the female receiving cavity 111. The limiting ring 112, fitted onto the protrusion 121, confines the protrusion 121 within the female receiving cavity 111, preventing the female buckle 11 and male buckle 12 from separating arbitrarily. When the female buckle 11 and male buckle 12 need to be separated, the protrusion 121 is forcefully pulled out of the female receiving cavity 111. This detachable cord buckle has a simple structure and can be made relatively small. When the female buckle 11 and male buckle 12 are combined, they function as a double-hole cord buckle; when separated, each buckle functions as a single-hole cord buckle, making it convenient to use and more suitable for adjusting cords in clothing and other fields, reducing the risk of injury from impacts.

[0040] Please refer to Figure 3 An annular limiting step 113 is provided in the female receiving cavity 111, and the side of the limiting ring 112 facing away from the first female opening 1111 abuts against the limiting step 113. When the protruding post 121 enters the female receiving cavity 111, it can prevent the limiting ring 112 from shifting inward.

[0041] Please refer to Figure 3 A rolled edge 114 is provided at the first female opening 1111, and a limiting ring 112 is limited between the rolled edge 114 and the limiting step 113. When the protrusion 121 leaves the female receiving cavity 111, it can prevent the limiting ring 112 from shifting outward. The rolled edge 114 is easy to process and prepare. The limiting ring 112 is placed on the limiting step 113, and the assembly of the limiting ring 112 can be completed by processing the rolled edge 114.

[0042] Please refer to Figure 3 The thickness of the rolled edge 114 gradually decreases from far away from the first female opening 1111 to near the first female opening 1111, which makes it easier to form the rolled edge 114 by deforming the ring wall inward during the rolling process, thereby limiting the limiting ring 112.

[0043] Please refer to Figure 4 The limiting ring 112 is made of copper and has a break 1121. This makes the limiting ring 112 sturdy and durable. The break 1121 allows the limiting ring 112 to deform, and the protrusion 121 can penetrate or exit the limiting ring 112 under the action of external force.

[0044] In other embodiments, the limiting ring 112 can be a rubber ring.

[0045] Please refer to Figure 6 The end of the protruding post 121 is provided with a rounded corner to facilitate passing through the limiting ring 112.

[0046] Please refer to Figure 6 The outer periphery of the protruding post 121 is provided with an annular limiting groove 1211. When the male buckle 12 and the female buckle 11 are connected, the limiting ring 112 is located in the limiting groove 1211, which can make the limiting ring 112 lock the protruding post 121.

[0047] In other embodiments, the limiting ring 112 may be interference-fitted onto the protrusion 121.

[0048] Please refer to Figure 1 Both the male buckle 12 and the female buckle 11 are columnar, with the first female opening 1111 located on the end face of the female buckle 11, and the protruding post 121 located on the end face of the male buckle 12. This structure facilitates handheld docking.

[0049] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6The female buckle 11 includes a female main body 115, a female pressing member 116, and a female elastic member 117. The female main body 115 is cylindrical, and a female receiving cavity 111 is disposed in the female main body 115. The female receiving cavity 111 is also provided with a second female opening 1112. The second female opening 1112 and the first female opening 1111 are respectively located at the two axial ends of the female main body 115. The radial sidewall of the female main body 115 is provided with two opposing first female through holes 1151 for the first rope to pass through. The female pressing member 116 is movably disposed in the female receiving cavity 111 through the second female opening 1112. The female pressing member 116 is provided with a second female through hole 1161 for the first rope to pass through. The second female through hole 1161 can be aligned or misaligned with the two first female through holes 1151. A female elastic element 117 is disposed in a female receiving cavity 111 to provide elastic force, causing the female pressing element 116 to move away from the female receiving cavity 111. The male buckle 12 includes a male body 122, a male pressing element 123, and a male elastic element 124. The male body 122 is columnar, with a protruding post 121 disposed at one axial end. The male body 122 has a male receiving cavity 1221, and an open end 1222 is provided at the other axial end of the male receiving cavity 1221. Two opposing first male through holes 1223 are provided on the radial sidewall of the male body 122 for a second cord to pass through. The male pressing element 123 is movably disposed in the male receiving cavity 1221 through the open end 1222. The male pressing element 123 has a second male through hole 1231 for a second cord to pass through. The second male through hole 1231 can be aligned or misaligned with the two first male through holes 1223. The male elastic element 124 is disposed in the male receiving cavity 1221 to provide elastic force, causing the male pressing element 123 to move away from the male receiving cavity 1221. The first female through hole 1151 and the second female through hole 1161 are arranged radially along the female buckle 11, and the first male through hole 1223 and the second male through hole 1231 are arranged radially along the male buckle 12, which facilitates pulling the rope, and the force during pulling will not cause the protrusion 121 to disengage from the female receiving cavity 111.

[0050] Both the female elastic element 117 and the male elastic element 124 are configured as compression springs. The axial direction of the female elastic element 117 is aligned with the axial direction of the female buckle 11, and the axial direction of the male elastic element 124 is aligned with the axial direction of the male buckle 12. Pressing down will make the male buckle 12 and the female buckle 11 more tightly connected and less likely to come loose.

[0051] How to use the detachable cord buckle according to a preferred embodiment of this utility model:

[0052] The first cord is threaded through two first female through holes 1151 and two female through holes 1161. Pressing the female pressing member 116 aligns the two first female through holes 1151 and two female through holes 1161. The female buckle 11 can be slid along the first cord for adjustment. Then, releasing the female pressing member 116 causes the two first female through holes 1151 and two female through holes 1161 to misalign, and the relative position of the first cord and the female buckle 11 is fixed. The first cord is threaded through two first male through holes 1223 and two male through holes 1231. Pressing the male pressing member 123 aligns the two first male through holes 1223 and two male through holes 1231. The male buckle 12 can be slid along the second cord for adjustment. Then, releasing the male pressing member 123 causes the two first male through holes 1223 and two male through holes 1231 to misalign, and the relative position of the second cord and the male buckle 12 is fixed.

[0053] When the female buckle 11 and male buckle 12 need to be combined, forcefully insert the protrusion 121 into the female receiving cavity 111, with the limiting ring 112 located in the limiting groove 1211. When the female buckle 11 and male buckle 12 need to be separated, forcefully pull the protrusion 121 out of the female receiving cavity 111.

[0054] This completes the method of using the detachable cord buckle according to the preferred embodiment.

[0055] This utility model relates to a detachable cord buckle. When the female and male buckles need to be combined, the protruding post is forcefully inserted into the female receiving cavity.
