[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0030] The terms "first" and "second" in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor as limiting the order of precedence.

[0031] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in Figure 1 This is a reference diagram of the usage status of the preferred embodiment of the present utility model. Figure 2 This is a schematic diagram of the main structure of the rope buckle of the preferred embodiment of the present utility model Figure 1 . Figure 3 This is a schematic diagram of the main structure of the rope buckle of the preferred embodiment of the present utility model Figure 2 .

[0032] The following is a preferred embodiment of a spring-free cord lock provided by the present invention that can solve the above technical problems.

[0033] The preferred embodiment of the spring-free cord lock provided by the present invention comprises a cord lock body 11. The cord lock body 11 comprises a fixing portion 111, a guide portion 112, and a locking portion 113. The fixing portion 111 is located in the middle of the cord lock body 11 and is provided with two oppositely positioned fixing holes 1111. These two fixing holes 1111 are used to secure the ends of the cord 12, ensuring that one end of the cord 12 is securely connected to one side of the cord lock while the other end passes through the other fixing hole 1111, ready for subsequent winding and securing operations.

[0034] The guide portion 112 is located at the bottom of the fixing portion 111. Its design helps the user guide the cord 12 along a specific path, facilitating subsequent securement. The engaging portion 113 is located at the top of the fixing portion 111 and includes a slot 1131 therein; slot 1131 is used to receive and retain the portion of the cord 12 after it has been routed around the guide portion 112.

[0035] The cord lock body 11 serves as the foundation of the overall structure. Its design enables the cord lock to stably secure the cord 12 and, through a specific structure, allows the cord 12 to be routed and engaged. This design eliminates the need for a spring, simplifies the structure, reduces costs, and improves ease of use and reliability.

[0036] The structure of the cord lock body 11 in this embodiment is described in detail as follows:

[0037] Combine Figure 2 In this embodiment, a plurality of anti-slip stripes 1132 are provided on both sides of the slot 1131, evenly spaced vertically. The presence of the anti-slip stripes 1132 increases the friction between the slot 1131 and the rope 12, thereby preventing the rope 12 from slipping or accidentally falling off within the slot 1131, further enhancing the fastening stability of the rope buckle.

[0038] Combine Figure 4 In this embodiment, the straight line in which the slot 1131 extends is parallel to the central axis of the fixing hole 1111, and the cross-sectional width of the slot 1131 gradually increases on the side away from the guide portion 112. This design helps to more easily receive and clamp the portion of the rope 12 after it has passed around the guide portion 112.

[0039] Combine Figure 3 In this embodiment, a guide groove 1121 is provided within the cord lock body 11. The central axis of the guide groove 1121 is parallel to the central axis of the fixing hole 1111, ensuring that the cord 12 can smoothly follow the pre-set path. The guide groove 1121 provides a clear path for the cord 12 to follow, ensuring that it follows the pre-set path. This helps reduce wear and tear on the cord 12 and improves the efficiency of the cord lock.

[0040] Along the winding direction of the rope 12, the width of the guide groove 1121 gradually decreases; as the winding direction of the rope 12 changes, the width of the guide groove 1121 gradually decreases, which helps to guide the rope 12 to fit more closely in the guide groove 1121, further enhancing the stability of the connection between the rope buckle and the rope 12.

[0041] The second embodiment of the present invention is provided as follows:

[0042] like Figure 5As shown, this embodiment is substantially the same as the first embodiment, but differs in the design of the slot 1131 of the engaging portion 113. Specifically, the slot 1131 in this embodiment is arranged in a curved shape. This curved slot 1131 better adapts to the detour path of the cord 12, allowing the cord 12 to fit more tightly within the slot 1131 after detour, thereby improving the fastening effect and stability of the cord lock.

[0043] The bent-shaped slot 1131 can better adapt to the shape and winding direction of the rope 12, so that the rope 12 can fit more closely in the slot 1131, which helps to improve the stability of the rope buckle.

[0044] In this embodiment, the cross-section of the latching slot 1131 is a "V"-shaped structure (it may also be a "C"-shaped or "U"-shaped or other shapes). This structure can provide better latching effect and stability.

[0045] The guide groove 1121 in this embodiment can also be a guide channel structure. The guide channel provides a more defined path for the rope 12 to pass through, helping to reduce friction and wear of the rope 12. The guide portion 112 in this embodiment is optimized to provide a smoother guide channel to ensure that the rope 12 does not experience excessive resistance or wear during the winding process.

[0046] The working principle of this utility model:

[0047] Inserting the rope 12: The two ends of the rope 12 are respectively passed through the two fixing holes 1111 on the rope lock body 11 and tightened to the appropriate position. The two ends of the rope 12 are aligned and overlapped for the subsequent winding operation.

[0048] Rope 12 is wound around: The overlapped portion of rope 12 is wound around along the track (guide groove 1121 or guide channel) preset by guide portion 112. During the winding process, it is ensured that rope 12 does not deviate from the track and smoothly reaches the position where the engaging portion 113 is located.

[0049] The rope 12 is locked: When the folded portion of the rope 12 passes around the locking portion 113, it is pressed into the locking groove 1131. The rope 12 fits tightly into the locking groove 1131 and is fixed by the anti-slip stripes 1132. At this point, the rope 12 is firmly fixed to the rope buckle.

[0050] The spring-free cord lock provided by the present invention primarily utilizes the winding and locking principles of the cord 12 to achieve a secure fit. By designing the guide portion 112 and the locking portion 113 in a well-designed structure, the cord 12 can be wound along a predetermined track and ultimately locked into the locking slot 1131.

[0051] This completes the use of the spring-free cord lock of the preferred embodiment.

[0052] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
