[0042] See Figures 1 to 10One embodiment of this application provides a rope end buckle, including: a female buckle 1 and a male buckle 2 inserted into the female buckle 1;

[0043] The female buckle 1 includes a shell with a cavity structure. The cavity structure communicates with the outside through a first opening 101 on a first side end face, a second opening 102 on a second side end face, a third opening 1031 on a third side end face 103, and a fourth opening 1041 on a fourth side end face 104. The first side end face and the second side end face are symmetrically arranged about a first centerline axis. The third side end face 103 is opposite to the fourth side end face 104 and is perpendicular to the first centerline. The size of the third opening 1031 is larger than the size of the fourth opening 1041, and the projection of the fourth opening 1041 on the plane where the fourth side end face 104 is located is I-shaped. The first opening 101 and the third opening 1031, as well as the second opening 102 and the third opening 1031, respectively form a channel for the rope 3 to pass through.

[0044] The male buckle 2 includes: an elastic element 201, a fixing part 202, and a frame structure 203 disposed on the fixing part 202. The fixing part 202 is provided with snap-fit ​​structures 2021 at both ends corresponding to the first side end face and the second side end face, and the size of the fixing part 202 corresponds to the third opening 1031. The end of the frame structure 203 away from the fixing part 202 corresponds to the size of the fourth opening 1041.

[0045] When the male buckle 2 is inserted into the female buckle 1, a portion of the frame structure 203 protrudes through the female buckle 1 through the fourth opening 1041. The elastic member 201 is disposed between the fixing part 202 and the fourth side end face 104, and is located inside the frame.

[0046] When the rope end buckle is in the unlocked state, the fixing part 202 compresses the elastic member 201 and moves it closer to the fourth side end face 104. When the rope end buckle is in the locked state, the fixing part 202 moves away from the fourth side end face 104, and the snap-fit ​​structure 2021 cooperates with the snap-fit ​​side wall 1032 corresponding to the third opening 1031 to lock the rope 3.

[0047] This embodiment provides an example of the rope end buckle provided in this application, wherein the rope end buckle includes a male buckle 2 and a female buckle 1, and the male buckle 2 is inserted into the inside of the female buckle 1. For ease of understanding, the structures of the male buckle 2 and the female buckle 1 are described here first.

[0048] The female buckle 1 includes a shell with a cavity structure for inserting the male buckle 2 and threading the rope 3. The shell protects the structural strength of the female buckle 1. Specifically, the cavity structure is connected to the outside through openings on the side end faces of the shell, namely the first opening 101 on the first side end face, the second opening 102 on the second side end face, the third opening 1031 on the third side end face, and the fourth opening 1041 on the fourth side end face. The first side end face and the second side end face are symmetrical about the first centerline axis, and the third side end face 103 and the fourth side end face 104 are opposite to each other and perpendicular to the first centerline. Specifically, the first opening 101 and the third opening 1031 form a channel for the rope 3 to pass through, and the second opening 102 and the third opening 1031 also form a channel for the rope 3 to pass through, so that the female buckle 1 can accommodate two ropes 3; the size of the third opening 1031 is larger than the size of the fourth opening 1041, and the projection of the fourth opening 1041 onto the plane of the fourth side end face 104 forms an I-shape (e.g., Figure 10 (as shown), so as to facilitate the insertion of the male buckle 2 and prevent the male buckle 2 from protruding from the fourth opening 1041;

[0049] The male buckle 2 includes an elastic element 201, a fixing part 202, and a frame structure 203 disposed on the fixing part 202. The fixing part 202 has two snap-fit ​​structures 2021 at its two ends corresponding to the first and second side faces, respectively. The size of the fixing part 202 corresponds to the third opening 1031, so that after the male buckle 2 is inserted into the female buckle 1, the snap-fit ​​structure 2021 and the snap-fit ​​sidewall 1032 corresponding to the third opening 1031 cooperate to form a space to accommodate the rope 3. Furthermore, by adjusting the position of the fixing part 202, the size of the space formed by the snap-fit ​​structure 2021 and the snap-fit ​​sidewall 1032 can be adjusted, thus adapting to ropes 3 of different diameters. The portion of the frame structure 203 disposed on the fixing part 202 and away from the fixing part 202 corresponds to the fourth opening 1041 of the female buckle 1, facilitating the passage of the female buckle 1. After the male buckle 2 is inserted into the female buckle 1, the portion of the frame structure 203 away from the fixing part 202 passes through the female buckle 1, allowing the position of the male buckle 2 to be controlled through this portion. In one specific embodiment, the frame structure 203 includes two vertical beams extending along a first centerline based on the fixing part 202, and a horizontal beam connecting the two vertical beams at the ends away from the fixing part 202. An elastic member 201 is disposed inside the frame structure 203 and is used to connect to the fourth side end face 104 of the fixing part 202 and the female buckle 1, respectively. The frame structure 203 can guide and limit the elastic member 201, preventing it from detaching.

[0050] In practical use, the cooperation of male buckle 2 and female buckle 1 allows the entire rope end buckle to have both an unlocked state for moving the rope 3 and a locked state for restricting the movement of the rope 3. Specifically, when the rope end buckle is in the unlocked state, the fixing part 202 of male buckle 2 will move to a position close to the fourth side end face 104 of female buckle 1 under the action of external force through the compression elastic element 201, thereby increasing the space between the snap-fit ​​structure 2021 and the snap-fit ​​side wall 1032. Figure 8 As shown by the dotted line, this facilitates the movement of rope 3 and also represents the maximum rope diameter applicable to the rope end buckle. When the rope end buckle is in the locked state, the fixing part 202 of the male buckle 2 will move towards the third end face under the elastic force of the elastic element 201, thereby reducing the space between the snap-fit ​​structure 2021 and the snap-fit ​​sidewall 1032, as shown in the figure. Figure 4 As shown by the dotted line, it is used to lock the rope 3, and it is also the minimum rope diameter applicable to the rope end buckle.

[0051] In summary, this embodiment, through the design of the fixing part 202 in the male buckle 2 and the channel for the rope 3 to pass through in the female buckle 1, makes the space for the rope 3 to pass through adjustable, and can lock ropes 3 of different diameters, thereby improving the applicability of the rope end buckle and helping to reduce costs.

[0052] In one specific embodiment, the elastic element 201 is a metal telescopic spring. It should be noted that in use, the rope 3 can be loosened or relaxed by holding the rope 3 with one hand and applying external force to the frame of the male buckle 2 with the other hand; the tightening and loosening movements are in opposite directions. Alternatively, the female buckle 1 can be fixed with one hand, and the rope 3 can be pulled with the other hand, applying external force to the fixing part 202 of the male buckle 2 through the rope 3 to loosen it, thus achieving the tightening or relaxation of the rope 3.

[0053] See Figure 1 , 2 4, 5, 6, 8, 9, 12 or 13, preferably, as described above, the first side end face and the second side end face are formed as a first inclined surface connecting the third side end face 103 and the fourth side end face 104.

[0054] In this embodiment, the first and second side end faces are set as inclined surfaces. While ensuring the fit between the male buckle 2 and the female buckle 1, the cost is reduced by shrinking the size of the female buckle 1. At the same time, the inclined surface setting makes the orthographic projection of the upper end face 105 or the lower end face of the rope end buckle form an isosceles trapezoid or a structure similar to an isosceles trapezoid, which is also beneficial to improving the structural strength and structural stability of the female buckle 1.

[0055] See Figure 1 , 34, 5, 7, 8 or 9, preferably, as described above, the fixing part 202 is further provided with an installation structure 2022 for the elastic member 201 to be fitted, and the installation structure 2022 extends along the first center line.

[0056] In this embodiment, the fixing part 202 is also provided with an installation structure 2022 extending along the first center line. When installing the elastic element 201, the elastic element 201 is fitted onto the installation structure 2022, which can limit and guide the elastic element 201, preventing misalignment and other issues that could affect the normal use of the rope end buckle. Furthermore, the length of the installation structure 2022 can limit the compression degree of the elastic element 201, ensuring that the elastic element 201 is within a good compression range, thereby improving its service life.

[0057] See Figure 1 , 2 Preferably, as described above, the fourth opening 1041 of the cord end buckle extends to the first side end face and the second side end face.

[0058] In this embodiment, the fourth opening 1041 also extends to the adjacent first side end face and second side end face, so that part of the frame can pass through the extended opening, thereby allowing the size of the fourth side end face 104 to be further reduced, thereby reducing the size of the female buckle 1 and helping to reduce production costs.

[0059] See Figure 4 , 5 8 or 9, preferably, as described above, the snap-fit ​​sidewall 1032 has a second inclined surface that is inclined toward the first opening 101 or the second opening 102 respectively.

[0060] In this embodiment, the snap-fit ​​sidewall 1032 has a second inclined surface that is inclined toward the first opening 101 or the second opening 102, so that the third opening 1031 can smoothly transition to the first opening 101 or the second opening 102 inside the housing, avoiding the obstruction of the rope 3 passing through the channel due to the sharp corners, thereby facilitating the movement of the rope 3 in the channel.

[0061] See Figure 1 Alternatively, 4. Preferably, as described above, the rope end buckle includes a plurality of protrusions 20211 facing the first side end face or the second side end face, and the plurality of protrusions 20211 cooperate with the snap-fit ​​side wall 1032 to form a space for accommodating the rope 3.

[0062] In this embodiment, the snap-fit ​​structure 2021 has a plurality of protrusions 20211 on one end facing the first side face or the second side face. When locking the rope 3, the protrusions 20211 can be inserted into the rope 3, thereby improving the stability of locking the rope 3.

[0063] See Figure 1 Or 4, further, as described above, the rope end buckle, wherein a plurality of the protrusions 20211 are arranged in at least two columns, and each column has at least two of the protrusions 20211;

[0064] At least one auxiliary structure 20212 is formed between two adjacent columns. The auxiliary structure 20212 and the protrusion 20211 cooperate with the snap-fit ​​sidewall 1032 to form a space for accommodating the rope 3.

[0065] In this embodiment, the protrusions 20211 are provided in at least two rows, and each row has at least two protrusions 20211, thereby ensuring that at least one protrusion 20211 can be inserted into the rope 3 when the rope 3 is locked, further ensuring the stability of the rope 3 locking.

[0066] In addition, there is a certain interval between the two columns, which makes it easy to place part of the rope 3 within the interval, thus facilitating the locking of the large-diameter rope 3.

[0067] In one specific embodiment, at least one auxiliary structure 20212 is provided in the interval between two adjacent columns. The auxiliary structure 20212 is similar to the protrusion 20211, but its height is slightly lower than that of the protrusion 20211, so as to further reduce the space between the interval portion and the snap-fit ​​sidewall 1032. The auxiliary structure 20212 can also be inserted into the rope 3 to further ensure the stability of the rope 3 locking.

[0068] See Figure 11 Preferably, in the rope end buckle as described above, the fixing part 202 is further provided with a guide block 2023, and the third side end face 103 is provided with a guide groove 1033 corresponding to the guide block 2023, and the guide groove 1033 is connected to the third opening 1031.

[0069] In this embodiment, a guide block 2023 is provided on the fixing part 202, and a corresponding guide groove 1033 is provided on the third side end face 103. When the male buckle 2 is inserted into the female buckle 1, it can be guided by the guide block 2023 and the guide groove 1033 to ensure the smooth insertion of the male buckle 2.

[0070] See Figure 1 , 26, 12 or 13, preferably, as described above, the upper end face 105 and / or lower end face of the female buckle 1 are provided with an anti-slip structure 1051.

[0071] In this embodiment, the anti-slip structure 1051 allows the user to easily pinch the upper end face 105 and the lower end face of the female buckle 1 and push the female buckle 1 to move. Specifically, the user can hold the rope 3 passing through the rope end buckle with one hand and push the female buckle 1 to move in the opposite direction with the other hand to achieve relative movement between the rope end buckle and the rope 3, for example, to tighten the rope 3.

[0072] Preferably, the cord end buckle as described above further includes:

[0073] See Figure 12 Alternatively, 13, a pull-tail structure 4, wherein the pull-tail structure 4 is fixedly connected to the portion of the frame structure 203 through which the male buckle 2 passes the female buckle 1.

[0074] In this embodiment, the pull tail structure 4 is an extension structure used to partially connect with the frame structure 203, so that the male buckle 2 can be pulled by the pull tail structure 4 instead of the user directly pulling the frame structure 203, thereby improving the convenience of use for the user.

[0075] In one specific embodiment, the trailing structure includes a fixing structure and a trailing rope. Both ends of the trailing rope are fixed inside the fixing structure. The fixing structure includes, but is not limited to, a split structure with at least two parts and an integrally formed structure fixed to the trailing rope by heat fusion or the like. When fixing the trailing structure 4 and the frame structure 203, the trailing structure is tied to the frame structure 203 by passing the middle portion of the trailing rope through the frame structure 203 and then passing the fixing structure through the trailing rope. It should be noted that the style of the fixing structure can be set according to actual needs, and its specific style is not limited here.

[0076] Furthermore, reference numerals and / or letters may be repeated in different examples within this application. Such repetition is for the purpose of simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed.

[0077] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion.

[0078] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
