[0033] The utility model provides a shoelace buckle with a press-type operation. Figures 1 to 4 As shown, the shoelace buckle comprises a sub-buckle 1, a female buckle 2, and a pressing member 3. One end of each of the sub-buckle 1 and female buckle 2 is connected to a rotatable fastener 4 for securing the end of the shoelace. The other end of the sub-buckle 1 is provided with an insertion portion 11, which is provided with fixing holes 101 extending through both sides. The other end of the female buckle 2 has an inwardly recessed end surface forming an insertion slot 201. The insertion portion 11 of the sub-buckle 1 fits into the insertion slot 201 from the end surface of the female buckle 2, connecting the sub-buckle 1 and female buckle 2.

[0034] As attached Figures 8 to 10 As shown, both the sub-button 1 and the female button 2 are provided with a receiving groove 401 at one end of the connecting fastener 4, and the connection method is that the side walls on both sides of the receiving groove 401 are provided with connecting holes 402, and both sides of one end of the fastener 4 are provided with protruding shafts 41, and the two shafts 41 are respectively embedded in the connecting holes 402 on both sides of the receiving groove 401, and as shown in the attached Figure 4 and 6 As shown, there is a gap between the rotating shaft 41 and the inner surface of the receiving groove 401, along which the end of the shoelace 6 is inserted into the receiving groove 401. A row of fastening teeth 42 is provided at the other end of the fastener 4. When the fastener 4 is rotated to be located within the receiving groove 401, the fastening teeth 42 rotate into the receiving groove 401 to press the shoelace 6, thereby securely connecting one end of the shoelace 6 to the sub-buckle 1 or the female buckle 2. Furthermore, a recessed slot 403 is provided on a side of the fastener 4 corresponding to the receiving groove 401. The shoelace 6 is inserted into the receiving groove 401 through the slot 403. When the fastening teeth 42 rotate into the receiving groove 401 until they align with the slot 403, the fastening teeth 42 press the portion of the shoelace 6 that has passed through the slot 403 into the slot 403, thereby enhancing the secure connection between the shoelace 6 and the sub-buckle 1 or the female buckle 2.

[0035] As attached Figure 7 As shown, a mounting hole 202 is further provided on one side of the female buckle 2. The mounting hole 202 extends into the insertion slot 201, and the side wall of the mounting hole 202 protrudes from the side wall of the insertion slot 201 to form a first blocking portion 21. Two corresponding side walls of the mounting hole 202 are also parallel to each other. Preferably, the mounting hole 202 can be a rectangular through hole. Figure 11 One side of the pressing member 3 is the operating surface 31, and the other side of the pressing member 3 is also provided with a protruding connecting sleeve 32, which is connected to the spring 5. The connecting structure can be as shown in the attached figure. Figure 6 、 11 As shown in FIG12 , the end surface of the connecting sleeve 32 is recessed to form a mounting groove 301, into which one end of the spring 6 is adapted to fit. A curved hook 33 is provided on one side of the connecting sleeve 32, and a protruding second blocking portion 34 is provided on the side of the connecting sleeve 32. The connecting sleeve 32 is inserted into the insertion groove 201 along the mounting hole 202 until the second blocking portion 34 passes through the first blocking portion 21 and is located within the insertion groove 201. The elastic force of the spring 5 then pushes the pressing member 3 toward the outside of the female snap 2, and the second blocking portion 34 abuts against the first blocking portion 21, thereby confining the connecting sleeve 32 and the hook 33 within the insertion groove 201.

[0036] In addition, two corresponding side surfaces of the connecting sleeve 32 are parallel to each other, and the two corresponding parallel side surfaces of the connecting sleeve 32 are inserted into the insertion slot 201 along the two corresponding parallel side walls of the mounting hole 202, thereby restricting the connecting sleeve 32 from rotating relative to the female buckle 2, thereby ensuring that the hook 33 always corresponds to the notch position of the insertion slot 201. Before the insertion portion 11 of the sub-buckle 1 is inserted into the insertion slot 201, the operating surface 31 is first pressed until the hook 33 moves to the bottom surface lower than the insertion slot 201. Then, the insertion portion 11 is inserted into the insertion slot 201 and the pressing member 3 is released. The elastic force of the spring 5 pushes the pressing member 3 toward the outside of the female buckle 2, causing the hook 33 to move to the fixing hole 101 that buckles the insertion portion 11, thereby achieving a fixed connection between the sub-buckle 1 and the female buckle 2.

[0037] In the above structure, the hollow interior of the connecting sleeve 32 due to the mounting slot 301 creates an elastic structure, allowing the sidewalls of the connecting sleeve 32 to contract inward and then expand. When connecting the pressing member 3 to the female snap 2, the connecting sleeve 32 is forcefully inserted from the mounting hole 202 into the insertion slot 201. At this point, the first blocking portion 21 blocks the second blocking portion 34, causing the sidewalls of the connecting sleeve 32 to contract inward until the second blocking portion 34 passes through the first blocking portion 21 and enters the insertion slot 201, allowing the end of the spring 5 exposed from the mounting slot 301 to abut against the surface within the insertion slot 201. This creates a structure in which the first blocking portion 21 blocks the second blocking portion 34 within the insertion slot 201, confining the connecting sleeve 32 within the insertion slot 201 and effectively limiting the travel of the pressing member 3 being pushed out of the insertion slot 201 by the spring, thereby maintaining the pressing member 3 connected to the female snap 2 and preventing it from separating.

[0038] Further, refer to the attached Figure 5 As shown, the first blocking portion 21 has a first inclined guide surface 211 facing the outside of the mounting hole 202. When the connecting sleeve 32 is inserted into the insertion groove 201 along the mounting hole 202, the second blocking portion 34 presses against the first guide surface 211 and is inserted into the insertion groove 201. It can be seen that the structure of the first guide surface 211 makes the process of inserting the connecting sleeve 32 into the insertion groove 201 along the mounting hole 202 more convenient and labor-saving. Figure 12 The side of the second blocking portion 34 facing away from the operating surface 31 is an inclined second guide surface 341. When the connecting sleeve 32 is inserted into the insertion slot 201 along the mounting hole 202, the second guide surface 341 presses against the first blocking portion 21 and is inserted into the insertion slot 201. Similar to the first guide surface 211 described above, the structure of the second guide surface 341 also makes the process of inserting the connecting sleeve 32 into the insertion slot 201 along the mounting hole 202 more convenient and labor-saving.

[0039] In summary, after the two ends of the shoelace 6 are fixed with the sub-buckle 1 and the female buckle 2, the user holds the sub-buckle 1 and the female buckle 2 with both hands during operation. The hand holding the female buckle 2 presses the operating surface 31 of the pressing member 3 and presses into the female buckle 2, causing the hook 33 to move to the side adjacent to the insertion slot 201. The insertion portion 11 of the sub-buckle 1 is then inserted along the insertion slot 201 on the end face of the female buckle 2. The pressing member 3 is then released, causing the spring 5 to push the connecting sleeve 32 outward from the female buckle 2, driving the hook 33 to hook into the fixing hole 101 of the insertion portion 11, thereby achieving a fixed connection between the sub-buckle 1 and the female buckle 2, thereby connecting the two ends of the shoelace. This operation method is very convenient, as the connection of the two ends of the shoelace can be completed by pressing and inserting without tying the shoelaces. The elastic force of the spring 5 can also keep the hook 33 hooked into the fixing hole 101, thereby maintaining a stable and non-separable connection between the sub-buckle 1 and the female buckle 2, preventing the sub-buckle 1 and the female buckle 2 from separating during walking.

[0040] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
