Description

Technical Field

[0001] The utility model relates to the technical field of footwear tools, in particular to a buckle. Background Art

[0002] As an intermediary connecting two objects, buckles have been widely used in daily life and can be seen everywhere on backpacks, clothing and other wearable items or daily necessities.

[0003] Lace-up shoes (or lace-up shoes) are shoes that are made by tightening the ropes (shoelaces) worn on the shoes to prevent them from easily falling off the wearer's feet. In order to simplify or replace the operation of tying the laces, a buckle is added to one part of the shoelaces to tighten the shoelaces. Among them, the most common buckle is the rotating button, which can be tightened by simply rotating the main body. However, since the rotating button needs to have enough space inside the main body to store excess shoelaces, it will be relatively large in size. Compared with conventional shoes, it will appear more abrupt from a visual perspective, affecting the overall aesthetics of the shoes. As an alternative, a snap buckle will be used, which has a component installed on the surface of the shoe and another component connected to the shoelaces. The two components can be buckled together to lengthen the shoelaces to tighten the shoelaces.

[0004] For example, the utility model patent with the announcement number CN205611938U discloses a rope tail positioning buckle, including a docking seat and a rope tail buckle body, wherein the docking seat has a base with a channel formed inside, and holes for the rope to pass through are provided on both sides of the channel, and a positioning portion is provided on the rear side of the base, and the rope tail buckle body has a base with through holes on both sides of the base opening backwards for the two ends of the rope to pass through, and the bottom surface of the base is respectively provided with recesses connected to the through holes for With a receiving groove for accommodating the stopper structure on the tail, and a docking portion being provided between the two receiving grooves at the front side of the base, the docking portion of the rope tail buckle body can be used as a positioning portion for the docking seat positioned on the combined object (such as a shoe body), so that the tail of the rope will not swing arbitrarily, and it has the safety of preventing stepping on or foreign objects hooking the rope and tripping. When the user wants to take the rope tail buckle body or adjust the tightness of the rope, it can be separated from the docking seat by only pulling it lightly sideways, and it conforms to the hand convenience of one-handed operation. The docking seat can be regarded as fixed on the surface of the shoe body, and the rope tail buckle body and the docking seat are buckled with each other. A press buckle is further combined on the rope between the rope tail buckle body and the shoe body. The tails of the two ends of the rope pass through the press buckle, and a knot is tied respectively to form a stopper structure and stored inside the rope tail buckle body. The tightness of the shoelaces can be adjusted by moving the press buckle. However, the rope tail positioning buckle structure still has the problems of large size, many parts, and complicated production. In addition, the adjustment method of moving the pressing buckle along the length of the shoe is not convenient whether in a squatting position or a sitting position. The rope tail positioning buckle can only be used with a specially designed shoe body and shoelace perforation method, and is not universal for ordinary lace-up shoes. Utility Model Content

[0076] Embodiment 1

[0077] like Figures 1 to 11 The figure shows the first embodiment of the buckle provided by the utility model. The buckle of the embodiment of the utility model is used on a shoe body.

[0078] See also Figure 1 , Figure 2 and Figure 3 The buckle of the first embodiment includes a male buckle 1 and a female buckle 2. The male buckle 1 is fixedly connected to the shoe surface 3 of the shoe body, and a male buckle clamping portion 10 is provided on the male buckle 1. A female buckle clamping portion 20 and a female buckle through hole 21 are provided on the female buckle 2. The female buckle clamping portion 20 and the male buckle clamping portion 10 are detachably clamped and matched, and the female buckle through hole 21 is for the shoelace 4 to pass through. The shoelace 4 is passed through the shoelace hole 5 on the shoe surface 3 of the shoe body. In order to facilitate the connection and matching between the female buckle 2 of the buckle and the shoelace 4, preferably, the male buckle 1 clamped and matched with the female buckle 2 is fixedly connected to the position of the shoe surface 3 near the shoelace hole 5, and the closer to the shoelace hole 5 above the shoe surface 3, the more convenient it is to operate. In order to facilitate the clamping of the female buckle 2 and the male buckle 1, preferably, there is a gap between the male buckle clamping portion 10 on the male buckle 1 and the shoe surface 3. When the shoe is put on, the shoelace 4 passes through the shoelace hole 5 and the female buckle through hole 21 on the female buckle 2, and the two ends of the shoelace 4 are tied to form a knot, which is in a state of being tightly tied and cannot be loosened, and the female buckle clamping part 20 of the female buckle 2 is clamped on the male buckle clamping part 10 of the male buckle 1, and the shoelace 4 is tightened through the shoelace hole 5 and the female buckle through hole 21. In the adjustment state, the female buckle 2 can be pulled to separate the female buckle clamping part 20 of the female buckle 2 from the male buckle clamping part 10 of the male buckle 1, and then the female buckle 2 can be loosened to loosen the shoelace 4, and the combination of a part of the shoelace 4 and the shoe body can be quickly loosened without untying the knotted ends of the shoelace 4, so that the shoelace 4 can be loosened in a state where the two ends of the shoelace are tied tightly but not loosened, so that the shoes can be quickly taken off or put on. After putting on the shoes, pull the female buckle 2 and re-engage the female buckle engaging portion 20 of the female buckle 2 on the male buckle engaging portion 10 of the male buckle 1, so that the shoelace 4 is tightened and the putting on of the shoes is completed.

[0079] The buckle of this embodiment directly connects the male buckle 1 to the shoe surface 3 of the shoe body, and connects the female buckle 2 to the shoelace 4. The installation is very convenient, and the shoe body does not need to be changed. The buckle can be conveniently installed on the lace shoe without changing the ordinary lace shoe, and the versatility is very good. After the buckle of this embodiment is installed on the lace shoe, the female buckle perforation 21 of the female buckle 2 and the shoelace hole 5 can be used to tighten the shoelace 4 with the knotted rope ends at both ends; by separating the female buckle 2 and the male buckle 1, a part of the shoelace 4 can be quickly loosened from the shoe body without untying the knotted rope ends of the shoelace 4, so that the shoes can be quickly taken off or put on. The snap-fitting and separation of the female buckle 2 and the male buckle 1 can be carried out by moving the female buckle 2 from the side of the shoe body. Whether in a squatting position or a sitting position, the adjustment operation is very convenient. In addition, the buckle structure of this embodiment is very simple, with few parts, and easy to produce.

[0080] In this embodiment 1, preferably, see Figures 4 to 7 , the male buckle 1 is connected to the shoe surface 3 by a rivet 6. The male buckle 1 is fixedly connected to the shoe surface 3 of the shoe body by the rivet 6, so that the male buckle 1 can be easily connected and fixed to the shoe surface 3 at any required designated position on the shoe surface 3, thereby increasing the flexibility and adaptability of the buckle of the first embodiment. The end face of the male buckle 1 close to the shoe surface 3 is the bottom surface of the male buckle 1. Preferably, a boss 11 is provided on the bottom surface of the male buckle 1. The boss 11 is located in the middle of the bottom surface of the male buckle 1 and protrudes from the bottom surface of the male buckle 1. The boss 11 is preferably a truncated cone. A countersunk hole 12 is provided on the boss 11. The countersunk hole 12 is formed by being recessed from the middle of one side of the boss 11 toward the shoe surface 3. The male buckle 1 is connected and fixed to the rivet 6 through the countersunk hole 12. By providing a boss 11 on the bottom surface of the male buckle 1, and connecting the rivet 6 with the countersunk hole 12 provided on the boss 11, a gap can be formed between the bottom surface of the male buckle 1 and the shoe surface 3, and only the side of the boss 11 facing the shoe surface 3 is in contact with the shoe surface 3, thereby reducing the contact area between the male buckle 1 and the shoe surface 3. Since the male buckle 1 is fixed to the shoe surface 3 by the rivet 6, if the contact area between the male buckle 1 and the shoe surface 3 is too large, the daily activities of the foot will drive the male buckle 1 to move, so that the male buckle 1 will move relatively significantly relative to the rivet 6, and thus it is easy to come off from the rivet 6. By providing a boss 11 on the bottom surface of the male buckle 1 to reduce the contact area between the male buckle 1 and the shoe surface 3, it is effectively avoided that the male buckle 1 is easily detached from the shoe surface 3 due to the daily activities of the foot due to the large contact area between the male buckle 1 and the shoe surface 3, and at the same time, the gap between the rivet 6 and the male buckle 1 is increased, thereby increasing the range of movement of the male buckle 1 on the shoe surface 3.

[0081] In this embodiment 1, preferably, see Figures 4 to 7The male buckle engaging portion 10 of the male buckle 1 is an annular engaging groove 10a provided on the outer peripheral surface of the male buckle 1. Preferably, the male buckle 1 has a main body 13 in the form of a circular column, and the engaging groove 10a is an annular groove provided on the outer peripheral surface of the main body 13. Figures 8 to 10 The female buckle engaging portion 20 of the female buckle 2 is a bayonet 20a provided on the female buckle 2, and the size of the bayonet 20a on the female buckle 2 matches the size of the bayonet 10a on the male buckle 1. The bayonet 20a can be inserted into the bayonet 10a from the outer peripheral side of the bayonet 10a to engage with the bayonet 10a, or the bayonet 20a can be inserted into the bayonet 10a from the end side of the bayonet 10a away from the shoe surface 3 to engage with the bayonet 10a.

[0082] The slot 10a on the male buckle 1 is formed by a slot profile, and the socket 20a on the female buckle 2 is formed by a socket profile. Figure 5 The slot profile of the slot 10a includes a slot annular surface 101 extending in the axial direction and two slot inclined surfaces 102 extending obliquely from both ends of the slot annular surface 101 in a direction away from the slot annular surface 101 toward the outer peripheral surface of the male buckle 1, thereby making the cross-sectional shape of the portion of the outer peripheral surface of the main body 13 of the male buckle 1 where the slot 10a is cut off to form a trapezoidal shape. Accordingly, the slot profile of the bayonet 20a is adapted to the slot profile of the slot 10a. Fig.10 The bayonet profile of the bayonet 20a includes a bayonet annular surface 201 extending in the axial direction and two bayonet inclined surfaces 202 extending obliquely from both ends of the bayonet annular surface 201 toward the outer peripheral side of the bayonet 20a in a direction away from the bayonet annular surface 201. When the bayonet 20a is inserted into the card slot 10a and engaged with the card slot 10a, the card slot annular surface 101 is fitted and connected with the bayonet annular surface 201, and the two card slot inclined surfaces 102 are fitted and connected with the two bayonet inclined surfaces 202 respectively. The two card slot inclined surfaces 102 of the card slot 10a and the two card slot inclined surfaces 202 of the bayonet 20a can play a role in guiding and buffering the transition. When the bayonet 20a on the female buckle 2 is inserted into the card slot 10a from the outer peripheral side of the card slot 10a, the two card slot inclined surfaces 102 and the two card slot inclined surfaces 202 can make the bayonet 20a deform slightly more smoothly and be inserted into the card slot 10a. When the bayonet 20a on the female buckle 2 is inserted into the slot 10a from the end of the slot 10a away from the shoe surface 3, the one of the two slot inclined surfaces 102 away from the shoe surface 3 and the two bayonet inclined surfaces 202 can guide the bayonet 20a to enter the slot 10a more smoothly. Preferably, the diameter of the slot annular surface 101 is equal to or slightly smaller than the diameter of the bayonet annular surface 201, so that the bayonet 20a can be more easily inserted and received in the slot 10a.

[0083] In this embodiment 1, preferably, see Figures 4 to 7, the end of the male buckle 1 away from the shoe surface 3 is a tapered end 14, and the slot 10a on the male buckle 1 is arranged on the side of the tapered end 14 close to the shoe surface 3, that is, the tapered end 14 is connected to the end side of the main body 13 provided with the slot 10a away from the shoe surface 3, and the diameter of the outer peripheral surface of the tapered end 14 gradually decreases in the direction away from the slot 10a. The end surface of the tapered end 14 away from the main body 13 is the top surface of the male buckle 1, and the diameter of the top surface of the male buckle 1 is the minimum diameter of the tapered end 14. The diameter of the top surface of the male buckle 1 is smaller than the maximum diameter of the outer peripheral surface of the main body 13, and the diameter of the top surface of the male buckle 1 is close to or equal to the minimum diameter of the slot 10a, and the minimum diameter of the slot 10a is the diameter of the slot annular surface 101. The maximum diameter of the tapered end 14 is equal to the maximum diameter of the outer peripheral surface of the main body 13 of the male buckle 1. The outer peripheral surface of the conical end 14 forms an inclined avoidance slope. When the bayonet 20a on the female buckle 2 is inserted into the slot 10a from the end side of the slot 10a away from the shoe surface 3, the bayonet 20a is inserted into the slot 10a through the transition of the avoidance slope of the conical end 14, which can make the bayonet 20a more smoothly inserted into the slot 10a from the end side of the slot 10a away from the shoe surface 3.

[0084] In this embodiment 1, preferably, see Figures 4 to 7 An extension portion 15 is formed between the male buckle engaging portion 10 (slot 10a) on the male buckle 1 and an end surface of the male buckle 1 close to the shoe surface 3 (the bottom surface of the male buckle 1). The extension portion 15 can be used as the main area for accommodating the rivet 6. The countersunk hole 12 extends from the boss 11 to the extension portion 15. At the same time, the extension portion 15 also creates a gap between the male buckle engaging portion 10 (slot 10a) and the shoe surface 3.

[0085] In this embodiment 1, preferably, see Figure 8 and Fig. 9 , the bayonet 20a on the female buckle 2 is provided with a notch as a transition opening 22, and the transition opening 22 provides a space for the male buckle 1 to pass through when the bayonet 20a on the female buckle 2 is inserted into the slot 10a from the outer peripheral side of the slot 10a on the male buckle 1. The bayonet annular surface 201 of the bayonet 20a is an incomplete ring due to the transition opening 22, and has two ends in the circumferential direction. Preferably, a transition surface 221 is extended from each of the two ends of the bayonet annular surface 201, and the two transition surfaces 221 are arranged opposite to each other in parallel and spaced apart, and are parallel to the axial direction of the bayonet 20a. The two ends of the transition surface 221 in the axial direction of the bayonet 20a are respectively extended obliquely toward the outer peripheral side of the bayonet 20a in a direction away from the transition surface 221 to form two transition inclined surfaces 222, and the interval space between the two transition surfaces 221 and the two pairs of transition inclined surfaces 222 constitutes the transition opening 22. The distance between the two transition surfaces 221 should ensure that the female buckle 2 will not be damaged due to excessive plastic deformation when the male buckle 1 passes through the transition surface 221, and the slot 10a on the male buckle 1 and the slot 20a on the female buckle 2 will not easily fall out after being engaged.

[0086] In this embodiment 1, preferably, see Figure 8 and Fig. 9 The female buckle 2 includes a snap-fitting portion 23 forming a bayonet 20a and a reinforcing portion 24 located on the periphery of the snap-fitting portion 23. The thickness of the snap-fitting portion 23 is not greater than the maximum axial height of the slot 10a on the male buckle 1 to ensure that the snap-fitting portion 20a can be snapped into the slot 10a. Preferably, the thickness of the snap-fitting portion 23 is close to or equal to the maximum axial height of the slot 10a on the male buckle 1 to ensure the stability of the snap-fitting between the snap-fitting portion 20a and the slot 10a. The thickness of the reinforcing portion 24 is greater than the thickness of the snap-fitting portion 23, and the female buckle through-hole 21 is provided on the reinforcing portion 24, thereby increasing the strength of the female buckle 2 and preventing the female buckle 2 from being easily damaged by the reverse forces from the left and right sides or the front and back sides.

[0087] Preferably, the reinforcement portion 24 of the female buckle 2 is U-shaped, the snap-fitting portion 23 is located at the inner bottom of the U-shaped reinforcement portion 24, and the transition opening 22 on the snap-fit ​​20a faces the opening of the U-shaped reinforcement portion 24, so that the female buckle 2 is U-shaped as a whole, and the female buckle 2 is connected by the opening of the U-shaped reinforcement portion 24 and the transition opening 22 on the snap-fit ​​20a to form a space for the male buckle 1 to pass through when the snap-fit ​​20a on the female buckle 2 is snapped into the slot 10a on the male buckle 1 from the outer peripheral side of the slot 10a.

[0088] In this embodiment 1, preferably, see Figure 8 and Fig.11 The axis of the female buckle through hole 21 on the female buckle 2 extends in a direction parallel to the shoe surface 3 and perpendicular to the axis of the bayonet 20a. Preferably, a female buckle through hole 21 is provided at both ends of the U-shaped reinforcement portion 24 of the female buckle 2 near the opening of the U-shaped reinforcement portion 24, and the axes of the two female buckle through holes 21 coincide. Figure 3 As shown, when the female buckle 2 is mounted on the shoelace 4, the two female buckle through holes 21 on the female buckle 2 can replace the two adjacent shoelace holes 5 on the same side of the shoe surface 3 for the shoelace 4 to pass through, so that the female buckle 2 can be attached to the shoe surface 3, so that the buckle does not appear abrupt on the shoe body, ensuring the appearance, and the male buckle 1 is fixedly installed at a position close to the position between the two adjacent shoelace holes 5. In this way, the female buckle 2 can be fastened or adjusted from the side of the shoe body, whether in a squatting position or a sitting position, it is convenient for the arm to apply force, and it can be adjusted and operated more easily.

[0089] In this embodiment 1, preferably, see Figure 8 and Fig. 9 The female buckle 2 is provided with a connecting groove 25, which is connected to the cloth belt 7 provided on the shoe body (such as Figure 3As shown in FIG. 1 ). By providing a cloth belt 7 on the shoe surface 3 of the shoe body to connect the connecting groove 25 on the female buckle 2, when moving the female buckle 2, the female buckle 2 can be moved by holding the cloth belt 7, which is convenient for operation; when the female buckle 2 is separated from the male buckle 1, the cloth belt 7 can also limit the female buckle 2 to clamp the shoelaces, preventing the female buckle 2 and the shoelaces from shaking at will. The surface of the cloth belt 7 can also be used to print a logo. In addition, the excess rope ends of the shoelaces 4 can also be stored in the connecting groove 25 on the female buckle 2.

[0090] In the first embodiment, the materials of the male buckle 1 and the female buckle 2 are not limited. The female buckle 2 can preferably be an injection molded part. If the male buckle 1 is made of a material with a harderness greater than that of the female buckle 2 or the same material as that of the female buckle 2, whether the female buckle 2 snaps into the slot 10a from the outer peripheral side of the slot 10a of the male buckle 1 or snaps into the slot 10a from the end of the slot 10a away from the shoe surface 3, when the snap ring surface 101 of the slot 10a or the avoidance slope 14 of the tapered end of the male buckle 1 contacts the transition surface 221 of the transition opening 22 of the snap 20a, the transition opening 22 of the snap 20a of the female buckle 2 will be slightly deformed and stretched, so that the snap 20a and the slot 10a can be smoothly snapped together, and then restored to their original state. If the male buckle 1 is made of a material with a lower hardness than the female buckle 2 , the male buckle 1 will be deformed during the above process, so that the snap-in 20 a and the snap-in slot 10 a can be smoothly snap-fitted and combined, and then return to their original state.

[0091] Embodiment 2

[0092] like Fig.12 and Fig.13 The second embodiment of the buckle provided by the utility model is shown in FIG. The second embodiment is basically the same as the first embodiment, and the similarities are not repeated here. The difference is that the way the male buckle 1 is fixedly connected to the shoe surface 3 of the shoe body is changed.

[0093] In the second embodiment, the male buckle 1 is provided with a male buckle through-hole 16 for the shoelace 4 to pass through, and the male buckle 1 is fixed to the shoe surface 3 by the shoelace 4 passing through the male buckle through-hole 16. Thus, the rivet 6 is omitted, and there is no need for the rivet 6 to pierce the shoe surface 3, and no damage is caused to the shoe body. Therefore, the buckle of the second embodiment can be conveniently installed on the lace-up shoe without damaging the ordinary lace-up shoe. Since there is no need to connect the rivet 6, there is no need to set the boss 11 and the countersunk hole 12 on the bottom surface of the male buckle 1.

[0094] In the second embodiment, preferably, the male buckle through hole 16 is provided on the extension portion 15 between the male buckle engaging portion 10 (slot 10a) on the male buckle 1 and an end surface of the male buckle 1 close to the shoe surface 3 (bottom surface of the male buckle 1).

[0096] Embodiment 3

[0097] like Figures 14 to 18 As shown, it is the third embodiment of the buckle provided by the utility model. This embodiment three is basically the same as the embodiment two, and the similarities are not repeated here. The difference is that in this embodiment three, an extension portion 15a is formed between the male buckle engaging portion 10 (slot 10a) on the male buckle 1 and an end surface of the male buckle 1 close to the shoe surface 3 (the bottom surface of the male buckle 1), and the cross section of the extension portion 15a gradually expands in the direction close to the shoe surface 3. The male buckle through hole 16 is provided on the extension portion 15a.

[0098] The third embodiment of the present invention increases the area of ​​the end face of the male buckle 1 close to the shoe surface 3 through the extension portion 15a, and correspondingly increases the contact area between the end face of the male buckle 1 close to the shoe surface 3 and the shoe surface 3, which can effectively increase the stability of the male buckle 1 fixed to the shoe surface 3 by the shoelace 4 passing through the male buckle through-hole 16.

[0099] In the third embodiment, preferably, the shape of the extension portion 15a is: when viewed from a side (such as Fig.16 The front view shown in FIG. 1 is a triangular pyramid, and when viewed from the adjacent side of the side (as shown in FIG. Fig.18 The male buckle 1 has a cylindrical shape (as shown in the left view). The axis of the male buckle through hole 16 passes through the conical surface of the extension portion 15a. Thus, while increasing the area of ​​the end surface of the male buckle 1 close to the shoe surface 3, the extension portion 15a is also made to be roughly triangular, rather than cylindrical. The triangular shape and the larger contact area between the male buckle 1 and the shoe surface 3 can prevent the male buckle 1 from turning upside down before being fastened with the female buckle 2 because the male buckle 1 and the shoe surface 3 are connected by a rope connected by the shoelace 4.

[0100] Embodiment 4

[0101] like Figures 19 to 22 The fourth embodiment of the buckle provided by the utility model is shown in FIG.

The difference is that the arrangement of the female buckle through hole 21 on the female buckle 2 is changed.

[0102] In the fourth embodiment, the axis of the female buckle through hole 21 on the female buckle 2 is parallel to the axis of the bayonet 20a, that is, the female buckle through hole 21 penetrates the female buckle 2 in a direction parallel to the axis of the bayonet 20a. Preferably, two female buckle through holes 21 are provided on both ends of the U-shaped reinforcement portion 24 of the female buckle 2 close to the opening of the U-shaped reinforcement portion 24, and the shoelace 4 passes through the four female buckle through holes 21. The form of the shoelace 4 passing through the four female buckle through holes 21 is not limited, as long as the female buckle 2 can pull the shoelace 4 when engaging or disengaging with the male buckle 1, so that the female buckle 2 and the male buckle 1 can be smoothly engaged or disengaged.

[0103] Preferably, in this fourth embodiment, see Fig.19 and Fig. 20 , a protrusion 210 is provided on the hole wall of the female buckle through-hole 21 on the female buckle 2, and the protrusion 210 is used to form an interference fit with the shoelace 4 passing through the female buckle through-hole 21 to clamp the shoelace 4, thereby providing a certain fixing force to fix the shoelace 4 to the female buckle through-hole 21, so that the shoelace 4 can be clamped by the female buckle 2. Preferably, there are multiple protrusions 210 on the hole wall of the female buckle through-hole 21, and the multiple protrusions 210 are evenly arranged along the circumference of the female buckle through-hole 21, which is conducive to increasing the fixing force of a single female buckle through-hole 21 on the shoelace 4. Preferably, the hole walls of the four female buckle through-holes 21 on the female buckle 2 are all provided with protrusions 210, which is conducive to enhancing the clamping of the female buckle 2 on the shoelace 4.
