Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Please refer to Figure 1 In this embodiment, a lock buckle that is easy to accurately position is provided, including a fixed buckle 1 and a movable buckle 2. The two sides of the fixed buckle 1 are respectively connected to the first connecting belt 3 and the second connecting belt 4, and one side of the movable buckle 2 is connected to the third connecting belt 5. The movable buckle 2 and the fixed buckle 1 are buckled together through a certain structure, and when the movable buckle 2 needs to be opened, the movable buckle 2 and the fixed buckle 1 are manually unfastened; in the underwear industry, the first connecting belt 3 and the second connecting belt 4 are respectively the upper shoulder strap and the lower shoulder strap of the underwear, and the third connecting belt 5 is the bra cup webbing, and the bra cup is opened for breastfeeding through the movable buckle 2. Similarly, the lock buckle that is easy to accurately position in this application can still be applied in the field of clothing, such as clothing, luggage accessories, etc.

[0037] Please refer to Figure 2 and Figure 3A lock hole 16 is provided in the middle of the fixing buckle 1, and a structural inclined surface 11 is provided on the inner wall of one side of the lock hole 16. The structural inclined surface 11 means that as the depth of the lock hole 16 increases, the inner wall of the lock hole 16 gradually extends toward the center of the lock hole 16, thereby forming a convex structure with an inclined surface on the upper side, and the inclined surface on the upper side is the structural inclined surface 11. A structural step 12 is provided on the inner wall of the lock hole 16 on the other side opposite to the structural inclined surface 11. The structural step 12 has a partially convex structure and a relatively partially concave structure, thereby forming a step-like structure.

[0038] Please refer to Figure 5 and Figure 6 A boss 21 is provided in the middle of the movable buckle 2, and the boss 21 is plugged into and matched with the lock hole; but since there is a structural inclined surface 11 inside the lock hole 16, and the structural inclined surface 11 can play a certain guiding role on the boss 21, an inclined wedge surface 22 that cooperates with the structural inclined surface 11 is provided on the wall surface of the boss 21 facing the structural inclined surface 11, so that the boss 21 moves along the structural inclined surface 11 through the extrusion effect, thereby improving the movement accuracy of the movable buckle 2, which is particularly suitable for users with inflexible fingers and users who operate with one hand, and can quickly and conveniently make the movable buckle 2 reach the specified position.

[0039] The boss 21 is provided with a slot 25 on one side of the cup body close to the movable buckle 2, and the boss 21 has at least one position relative to the structural inclined surface 11, so that the slot 25 corresponds to the position of the structural step 12. In other words, when the boss 21 slides along the structural inclined surface 11, it can slide to the position where the slot 25 corresponds to the position of the structural step 12. At this time, the concave structure of the slot 25 can correspond to the convex structure of the structural step 12, so that the slot 25 moves toward the structural step 12 through side sliding, thereby realizing the engagement of the slot 25 with the structural step 12, and then the movable buckle 2 is fastened to the fixed buckle 1.

[0040] In summary of the above embodiments, the present application provides a lock hole 16 on the fixed buckle 1, and the inner wall on one side of the lock hole 16 has a structural inclined surface 11, and the inner wall on the other side opposite to the lock hole 16 has a structural step 12; a boss 21 is provided on the movable buckle 2, and the boss 21 is plugged into and matched with the lock hole 16. An inclined wedge surface 22 is provided on the wall surface of the boss 21 facing the structural inclined surface 11, and the inclined wedge surface 22 can be wedge-matched with the structural inclined surface 11, so that the boss 21 can quickly and stably enter the lock hole 16 along the structural inclined surface 11. At the same time, a clamping groove 25 is provided on the side of the boss 21 close to the movable buckle 2. When the boss 21 moves to a certain position relative to the structural inclined surface 11, the clamping groove 25 can correspond to the position of the structural step 12, so that the side sliding clamping groove 25 moves toward the structural step 12, and finally the clamping match between the structural step 12 and the clamping groove 25 is achieved, so that the movable buckle 2 and the fixed buckle 1 are in a buckled state. Similarly, when the movable buckle 2 and the fixed buckle 1 are unfastened, the above steps can be reversed to achieve easy and quick release of the movable buckle 2 and the fixed buckle 1.

[0041] In addition, the lock hole 16 can be a through hole, that is, the lock hole 16 passes through the body of the fixed buckle 1, and the boss 21 can be inserted from one side of the lock hole 16. The lock hole 16 is provided with a rounded corner 15 on the side close to the movable buckle 2, please refer to Figure 2 and Figure 4 The setting of the rounded corner 15 can facilitate the insertion of the boss 21, that is, when the boss 21 is plugged into the lock hole 16, when the boss 21 does not completely correspond to the lock hole 16, the inclined wedge surface 22 of the outer wall of the boss 21 can abut against the rounded corner 15, so that the boss 21 can easily and quickly enter the lock hole 16 under the action of the rounded corner 15 and the inclined wedge surface 22. Figure 3 and Figure 4 The outer edge of the structural step 12 is provided with a step chamfer 17. The setting of the chamfer structure can make the card slot 25 structure on the boss 21 convenient and quick to engage with the structural step 12, improve the smoothness when buckling and unbuckled, so as to enhance the product usage experience.

[0042] Please refer to Figure 5 and Figure 6 The slot 25 is an annular slot, and the structural step 12 is an arc-shaped step that matches the structure of the slot 25. It should be noted that the provision of the annular slot allows the movable buckle 2 to be engaged with the structural step 12 at multiple angles, thereby improving the engagement flexibility of the movable buckle 2. At the same time, the annular structure of the slot 25 can improve the engagement stability of the slot 25 and the structural step 12 in the axial direction, thereby improving the fixing effect of the movable buckle 2 and the fixed buckle 1.

[0043] The first connecting belt through-holes 14 are provided on both sides of the fixed buckle 1, respectively for inserting the first connecting belt 3 and the second connecting belt 4 to connect with the fixed buckle 1. The second connecting belt through-hole 24 is provided on one side of the movable buckle 2, for inserting the third connecting belt 5 to connect with the movable buckle 2. The height of the first connecting belt 3 through-hole 14 and the second connecting belt through-hole 24 needs to be lower than the entire product to facilitate the insertion of the webbing, and at the same time, to avoid the friction caused by the webbing during the sliding engagement of the movable buckle 2 with the fixed buckle 1.

[0044] In other words, the connection position of the fixed buckle 1 and the first connecting belt 3 and the second connecting belt 4 is spaced apart from the movable buckle 2, and / or the connection position of the movable buckle 2 and the third connecting belt 5 is spaced apart from the fixed buckle 1. For details, please refer to Figure 7 and Figure 8 That is to say, the height of the perforation 14 of the first connecting belt 3 can be lower than the entire product, and the perforation 24 of the second connecting belt can be lower than the entire product, so that when the matching surfaces of the movable buckle 2 and the fixed buckle 1 are in contact, the first connecting belt 3 and the second connecting belt 4 are spaced apart from the movable buckle 2, and the third connecting belt 5 is spaced apart from the fixed buckle 1, so as to avoid the connecting belts affecting the sliding engagement between the movable buckle 2 and the fixed buckle 1.

[0045] The structural step 12 is located in the lock hole 16 and is arranged on one side close to any one of the through holes 14 of the first connecting belt 3; it should be pointed out that when the movable buckle 2 is connected to the third connecting belt 5, the force exerted on the movable buckle 2 usually comes from the direction of the third connecting belt 5, and the force exerted on the fixed buckle 1 usually comes from the joint action of the first connecting belt 3 and the second connecting belt 4. Therefore, in order to improve the fixing effect of the fixed buckle 1, the structural step 12 is preferably arranged on the side close to the through hole 14 of the first connecting belt 3. Therefore, when the movable buckle 2 is engaged with the fixed buckle 1 and the force of the movable buckle 2 acts on the structural step 12, the stability of the fixed buckle 1 can be improved by the first connecting belt 3 and the second connecting belt 4, thereby improving the engaging stability of the movable buckle 2.

[0046] The mating surfaces of the fixed buckle 1 and the movable buckle 2 are both embedded with magnets, that is, the first magnet 13 and the second magnet 23 are respectively arranged on the fixed buckle 1 and the movable buckle 2. Through the mutual attraction of the two magnets, the boss 21 gradually moves to the clamping position on the structural inclined surface 11, and at least when the clamping groove 25 is clamped with the structural step 12, the positions of the magnets correspond. In other words, when the positions of the two magnets correspond, the suction force should be the maximum. Therefore, before the clamping groove 25 is clamped with the structural step 12, the positions of the first magnet 13 and the second magnet 23 are not completely corresponding. Therefore, the magnetic force will force the boss 21 to slide along the structural inclined surface 11, and when the positions of the clamping groove 25 and the structural step 12 correspond, the clamping groove 25 can be clamped with the structural step 12 by using magnetic force or gently pushing the movable buckle 2, thereby improving the operability of the buckle. When the fixed buckle 1 and the movable buckle 2 are clamped and matched, the matching surfaces of the two fit together, so as to have a stable clamping effect.

[0047] Please refer to Fig. 9 When the movable buckle 2 is buckled with the fixed buckle 1, the boss 21 is first roughly aligned with the position of the lock hole 16. At this time, the positions of the magnets on the two buckles are not aligned. Then, under the joint magnetic attraction of the first magnet 13 and the second magnet 23, the boss 21 is forced to enter the lock hole 16 along the fillet 15 and abut against the structural inclined surface 11, thereby continuing to enter the lock hole 16 in a sliding posture until the position of the slot 25 corresponds to the position of the structural step 12. At this time, the matching surfaces of the movable buckle 2 and the fixed buckle 1 are fitted, and the boss 21 cannot continue to move into the lock hole 16; when the position of the slot 25 corresponds to the position of the structural step 12, under the action of the first magnet 13 and the second magnet 23, the movable buckle 2 can be gently pushed to make the slot 25 engage with the structural step 12, thereby realizing the buckling of the movable buckle 2 with the fixed buckle 1.

[0048] Please refer to Fig.10When the movable buckle 2 is unfastened from the fixed buckle 1, the movable buckle 2 is gently pushed to separate the slot 25 from the structural step 12, and when it is gently pushed to a certain position, the inclined wedge surface 22 of the boss 21 abuts against the structural inclined surface 11, and under continuous pushing, the boss 21 will move along the structural inclined surface 11 until it is separated from the fixed buckle 1, thereby achieving the unfastening of the movable buckle 2 from the fixed buckle 1.

[0049] In addition, the fixed buckle 1 and the movable buckle 2 of the present application are wide on both sides and narrow in the middle, and the design of the middle concave waist curve conforms to the human-machine relationship, which is convenient for users to better pinch and push, improve the product experience and easy to operate. At the same time, the curve design is softer and better meets the use scenario.

[0050] The present application also provides a kind of clothing, which includes any one of the above-mentioned buckles that facilitates precise positioning, and the buckle is provided on the clothing as an accessory.

[0051] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0052] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
