[0057] The following is a preferred embodiment of a spring-free same-mold self-clamping rope buckle provided by the present application, which can solve the above technical problems.

[0058] The preferred embodiment of the spring-free same-mold self-clamping rope fastener provided by the utility model is as follows: a spring-free same-mold self-clamping rope fastener, which comprises a first clasp 11 and a second clasp 12; the first clasp 11 is provided with a first mounting hole 111 and a first fixing hole 112, the first mounting hole 111 is in communication with the first fixing hole 112, the cross-sectional diameter of the first mounting hole 111 is larger than that of the first fixing hole 112; the second clasp 12 is identical in structure to the first clasp 11, the second clasp 12 is oppositely arranged with the first clasp 11, the second clasp 12 is provided with a second mounting hole 121 and a second fixing hole 122, the second mounting hole 121 is in communication with the second fixing hole 122, the cross-sectional diameter of the second mounting hole 121 is larger than that of the second fixing hole 122.

[0059] The second clasp 12 is slidably connected with the first clasp 11, and the sliding tracks of the first clasp 11 and the second clasp 12 comprise a mounting position and a fixing position. When the first clasp 11 and the second clasp 12 are located at the mounting position, the first mounting hole 111 is aligned with the second mounting hole 121, the first fixing hole 112 is misaligned with the second fixing hole 122, the surface of the first clasp 11 shields the second fixing hole 122, and the surface of the second clasp 12 shields the first fixing hole 112. When the first clasp 11 and the second clasp 12 are located at the fixing position, the first fixing hole 112 is aligned with the second fixing hole 122, the first mounting hole 111 is misaligned with the second mounting hole 121, the surface of the first clasp 11 shields the second mounting hole 121, and the surface of the second clasp 12 shields the first mounting hole 111.

[0060] The rope fastener is composed of the first clasp 11 and the second clasp 12, both of which are identical in structure and oppositely arranged, and the installation and fixing of the rope 13 are realized through the sliding connection. This design makes the structure of the rope fastener very simple, without complex mechanical structures and vulnerable parts, thereby reducing the manufacturing cost and the maintenance difficulty. Meanwhile, the sliding connection mode also makes the operation of the rope fastener very convenient. The user only needs to slide the first clasp 11 and the second clasp 12 to the corresponding positions, and then the installation and fixing of the rope 13 can be easily completed without using any tools or additional fasteners. When at the mounting position, the first mounting hole 111 is aligned with the second mounting hole 121, which facilitates the threading of the rope 13, the first fixing hole 112 is misaligned with the second fixing hole 122, and the surfaces of the first clasp 11 and the second clasp 12 shield them respectively, at this time, the rope is threaded. When at the fixing position, the first fixing hole 112 is aligned with the second fixing hole 122, at this time, the rope fastener is used to fix the rope 13. At this time, the first mounting hole 111 is misaligned with the second mounting hole 121, and the surfaces of the first clasp 11 and the second clasp 12 also shield them, which ensures that the rope 13 is firmly fixed in the hole and is not easy to loosen or fall off.

[0061] The structure of the spring-free same-mold self-clamping rope fastener in the embodiment will be described in detail as follows:

[0062] In combination Figure 1 and Figure 2 In this embodiment, the distance between the first mounting hole 111 and the second mounting hole 121 is greater than the distance between the first fixing hole 112 and the second fixing hole 122 along the projection of the plane where the first buckle 11 is located. In the installation position, the first mounting hole 111 and the second mounting hole 121 can have enough space to align, making it convenient for the rope 13 to pass through. At the same time, in the fixed position, the first fixing hole 112 and the second fixing hole 122 (when they are aligned) can tightly clamp the rope 13, ensuring the stability of the rope 13. The larger hole distance also reduces the risk of interference between the holes during sliding. At the same time, by setting two fixing holes between two mounting holes, compared with setting two fixing holes outside two mounting holes, the volume of the rope buckle in the fixed position is further reduced.

[0063] In this embodiment, the first buckle 11 includes a first card 113, a first sliding block 114, and a first fixing plate 115; the first card 113 is located at one end of the first buckle 11, and the first mounting hole 111 and the first fixing hole 112 are located on the first card 113; the first sliding block 114 is provided with two groups, and the two groups of first sliding blocks 114 are oppositely arranged on both sides of the first card 113; the first fixing plate 115 is located at the other end of the first buckle 11, and the first fixing plate 115 is provided with a first sliding groove at the bottom of both sides.

[0064] The second buckle 12 includes a second card 123, a second sliding block 124, and a second fixing plate 125; the second card 123 is located at one end of the second buckle 12, and the second mounting hole 121 and the second fixing hole 122 are located on the second card 123; the second sliding block 124 is provided with two groups, and the two groups of second sliding blocks 124 are oppositely arranged on both sides of the second card 123; the second fixing plate 125 is located at the other end of the second buckle 12, and the second fixing plate 125 is provided with a second sliding groove 126 at the top of both sides; wherein the first sliding block 114 and the second sliding groove 126 are in sliding connection, and the second sliding block 124 and the first sliding groove are in sliding connection.

[0065] The modular design of the first buckle 11 and the second buckle 12 makes the structure of the first buckle 11 and the second buckle 12 clear, easy to manufacture and assemble. At the same time, the function of each part is clear, which is convenient for users to understand and operate. By setting the mounting hole and the fixing hole on the card, the installation and fixing operation of the rope 13 is more intuitive and convenient. At the same time, the design of the card also increases the strength and stability of the rope buckle. The first buckle 11 and the second buckle 12 are respectively provided with two groups of sliding blocks, which makes the sliding connection between the first buckle 11 and the second buckle 12 more stable and reliable. The sliding block can evenly share the friction and pressure during sliding, prolonging the service life of the rope buckle.

[0066] The structure of the first fixed plate 115 in the embodiment will be described in detail as follows:

[0067] In combination Figure 1 In the embodiment, the first fixed plate 115 includes a first support part 1151, a first limiting part 1152, and a first extension part 1153. The first support part 1151 is connected to the first card 113 on one side. The stable connection between the first fixed plate 115 and the first card 113 ensures the integrity of the overall structure of the rope buckle under stress. At the same time, it is also convenient for users to clearly identify and operate each component when installing and fixing the rope 13. The first limiting part 1152 is provided with two groups, and the two groups of first limiting parts 1152 are respectively located on both sides of the bottom end of the first support part 1151. The plane where the first limiting part 1152 is located is parallel to the plane where the first support part 1151 is located. A uniform gap can be formed between the first limiting part 1152 and the first support part 1151, providing stable guidance for the sliding of the second sliding block 124. The setting of the two groups of limiting parts increases the stability and reliability of the first fixed plate 115. They can limit the movement range of the first and second buckles 11 and 12 during sliding, ensuring that they can accurately slide to the installation and fixing positions. The first extension part 1153 is vertically arranged on both sides of the bottom end of the first support part 1151, and the first extension part 1153 connects the first limiting part 1152 and the first support part 1151. The first extension part 1153 also plays a role in connecting the first limiting part 1152 and the first support part 1151, making the entire first fixed plate 115 a whole, improving the overall stability of the rope buckle. Among them, the first support part 1151, the first limiting part 1152, and the first extension part 1153 form a first sliding groove. The design of the first sliding groove makes the sliding connection between the first and second buckles 11 and 12 more smooth and stable, ensuring that the first and second buckles 11 and 12 can accurately slide to the required positions.

[0068] Further, the top surface of the first support part 1151 is flush with the plane where the top surface of the first card 113 is located, ensuring the flatness of the rope buckle in appearance. The plane where the top surface of the first sliding block 114 is located is below the plane where the top surface of the first card 113 is located, and the plane where the bottom surface of the first sliding block 114 is located is flush with the plane where the bottom surface of the first card 113 is located. The top surface of the first sliding block 114 is lower than the top surface of the first card 113, avoiding interference with the second card 123 or other components during sliding. At the same time, the bottom surface of the first sliding block 114 is flush with the bottom surface of the first card 113, ensuring the flatness and consistency of the sliding track, reducing the sliding resistance and wear caused by unevenness.

[0069] In this embodiment, along the projection of the first support part 1151, the arrangement direction of the first fixing hole 112 and the first mounting hole 111 is located between the two groups of first sliders 114. This structure design avoids the interference of the first fixing hole 112 and the first mounting hole 111 with the first slider 114 during sliding, improves the structural compactness of the rope buckle, helps to simplify the assembly process of the rope buckle, improves the assembly efficiency of the rope buckle, and ensures the firmness and reliability of the rope buckle when fixed.

[0070] In this embodiment, the first limiting part 1152 is provided with a first combining surface 11521 near the first card 113 side; when the first buckle 11 and the second buckle 12 are in the fixed position, the first fixing hole 112 and the second fixing hole 122 are aligned to form a fixed circular hole, and the plane where the first combining surface 11521 is located divides the fixed circular hole into two parts. The stability and reliability of the rope buckle in the fixed position. The arrangement of the first combining surface 11521 makes the first buckle 11 and the second buckle 12 tightly combined together when they are in the fixed position, forming a continuous plane. The plane where the first combining surface 11521 is located divides the fixed circular hole into two parts, and

[0071] The stability and reliability of the rope buckle in the fixed position are improved, and the loosening or damage caused by external force is prevented. This design helps to prolong the service life of the rope buckle and improve the overall performance of the rope buckle.

[0072] The structure of the second fixed plate 125 in this embodiment is described in detail as follows:

[0073] In combination Figure 1 , in this embodiment, the second fixed plate 125 includes a second support part 1251, a second limiting part 1252, and a second extension part 1253, one side of the second support part 1251 is connected with the second card 123; the second limiting part 1252 is provided with two groups, and the two groups of second limiting parts 1252 are respectively located on both sides above the second support part 1251, the plane where the second limiting part 1252 is located is parallel to the plane where the second support part 1251 is located; the second extension part 1253 is vertically arranged on both sides of the top end of the second support part 1251, and the second extension part 1253 connects the second support part 1251 and the second limiting part 1252; wherein, the second support part 1251, the second limiting part 1252 and the second extension part 1253 form a second sliding groove 126 through the combination design of the second support part 1251, the second limiting part 1252 and the second extension part 1253, forming a stable support and limiting structure, ensuring the stable movement of the sliding assembly in the predetermined track.

[0074] In this embodiment, the top surface of the second support part 1251 is flush with the top surface of the second card 123; the top surface of the second sliding block 124 is flush with the top surface of the second card 123, and the plane where the bottom surface of the second sliding block 124 is located is above the plane where the bottom surface of the second card 123 is located.

[0075] The design of the second sliding groove 126 and the height consistency of the second sliding block 124 and the top surface of the second card 123 ensure the smoothness and accuracy of the relative sliding of the first buckle 11 and the second buckle 12.

[0076] In this embodiment, in the projection along the plane where the second support part 1251 is located, the straight line where the arrangement direction of the second fixing hole 122 and the second mounting hole 121 is located is between the two groups of second sliding blocks 124, so that after the first buckle 11 and the second buckle 12 are engaged, the overall structure is more compact, which is beneficial to save space and reduce cost.

[0077] The second fixing hole 122 extends to the second support part 1251 away from the second mounting hole 121. The second limiting part 1252 is provided with a second combining surface on the side close to the second card 123; when the first buckle 11 and the second buckle 12 are in the fixed position, the second combining surface is attached to the first combining surface 11521. When the first buckle 11 and the second buckle 12 are in the fixed position, the attachment of the combining surface enhances the connection firmness of the structure and improves the stability and reliability of the overall structure.

[0078] Working principle of the utility model:

[0079] I. Installation of the rope 13.

[0080] Combining Figure 4 and Figure 5 , the first buckle 11 and the second buckle 12 are the same structure and are oppositely arranged. The user passes one end of the rope 13 through the aligned first mounting hole 111 and the second mounting hole 121. At this time, the first fixing hole 112 and the second fixing hole 122 are misaligned and are respectively blocked by the surfaces of the first buckle 11 and the second buckle 12, preventing the rope 13 from slipping out without being fixed.

[0081] The other end of the rope 13 can also be inserted in the same way, or other treatments (such as knotting, connecting other equipment, etc.) can be performed according to needs.

[0082] II. Fixing the rope 13.

[0083] Combining Figure 6 and Figure 7, the rope 13 is installed, the user slides the first buckle 11 and the second buckle 12 along the respective sliding grooves until they reach the fixed position. During the sliding process, the first sliding block 114 cooperates with the second sliding groove 126, and the second sliding block 124 cooperates with the first sliding groove, ensuring the stability and accuracy of the sliding.

[0084] When reaching the fixed position, the first fixing hole 112 and the second fixing hole 122 are aligned to form a continuous fixing circular hole for firmly clamping the rope 13. At the same time, the first mounting hole 111 and the second mounting hole 121 are misaligned and are blocked by the respective buckle surfaces, preventing the rope 13 from sliding out of the mounting hole.

[0085] In the fixed position, the joint surfaces (the first joint surface 11521 and the second joint surface) of the first buckle 11 and the second buckle 12 are in close contact, enhancing the structural connection firmness. The close contact of the joint surfaces and the alignment of the fixing holes together ensure that the rope 13 is firmly fixed in the hole and is not easy to loosen or fall off.

[0086] III. Disassembling the rope 13.

[0087] When it is necessary to disassemble the rope 13, the user only needs to slide the first buckle 11 and the second buckle 12 from the fixed position back to the mounting position, and the rope 13 can be easily taken out. The design of the rope buckle allows for repeated use without any tools or additional fasteners.

[0088] In this way, the use process of the spring-free same-mold self-clamping rope buckle of the preferred embodiment is completed.

[0089] In summary, although the utility model has been disclosed as above with the preferred embodiment, the above-mentioned preferred embodiment is not intended to limit the utility model. Those skilled in the art can make various changes and decorations without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model is subject to the scope defined by the claims.
