[0002] Various safety buckle structures are widely used in daily necessities, baby products, carrying systems, and outdoor equipment to achieve quick connection and release between components. Existing safety buckles can be broadly categorized into two-point and three-point structures, with two-point buckles being more widely used in the market due to their simple structure and lower cost. However, this structure generally suffers from poor locking stability and is susceptible to accidental loosening due to external forces, failing to meet the needs of scenarios with high safety requirements.

[0003] To address this, some improved magnetic three-point safety buckles have emerged. These typically feature two elastic arms and a central locking tongue that insert into the female buckle body, thereby enhancing its pull-out resistance. However, existing three-point structures still have several shortcomings: some products fail to effectively guide the insertion process within the structure, leading to misalignment of the plug and slot during assembly and affecting engagement efficiency; some designs lack stable positioning devices, relying solely on elastic components for limiting movement, which can easily lead to fatigue wear after long-term use, resulting in unstable engagement; and the unlocking operation of some products is relatively complex, making it inconvenient for users to operate with one hand or quickly, affecting ease of use.

Detailed Implementation

[0026] like Figures 1 to 8 As shown, a magnetic three-point safety buckle includes a main buckle 10, one side of which is connected to a first side buckle 20, and the other side of which is connected to a second side buckle 30. The first side buckle 20 and the second side buckle 30 are correspondingly connected. The inner surface of the main buckle 10 is recessed with a locking groove 11, and locking buttons 40 are connected to both sides of the locking groove 11. The side of the first side buckle 20 is provided with a locking protrusion 21, and the locking groove... A protruding slot 111 is provided in the middle of the main fastener 10. The locking protruding post 21 is connected in the protruding slot 111. At the same time, the two locking buttons 40 are locked and fixed to the locking protruding post 21. When unlocking is required, the user can press the locking buttons 40 on both sides of the main fastener 10 at the same time to release it from the locking protruding post 21. At this time, the first side fastener 20 and the second side fastener 30 can be pulled out from the main fastener 10 to achieve a fast and safe unlocking operation.

[0027] In practical implementation, the locking button 40 has symmetrically arranged elastic locking springs 41 on both sides of one end. Each locking spring 41 has a connecting locking buckle 42 at its end for locking the locking protrusion 21. The upper outer surface of the locking protrusion 21 has a circular locking recess 211 for engaging with the connecting locking buckle 42. To facilitate the insertion and fixation of the connecting structure, the upper side of the protrusion through groove 111 in the main fastener 10 has several locking through holes 112. These locking through holes 112 guide the connecting locking buckle 42 through and into the locking recess 211 when the locking protrusion 21 is inserted into the protrusion through groove 111. During the locking process, when the locking protrusion 21 is inserted into the protrusion slot 111, the two connecting latches 42 on the locking button 40, under the action of the locking spring 41, enter the protrusion slot 111 through the locking opening 112 and finally engage in the annular locking recess 211 of the locking protrusion 21, thereby achieving a locked connection between the locking button 40 and the locking protrusion 21. During use, when the locking buttons 40 on both sides of the main fastener 10 are not pressed, the connecting latches 42 are limited by the locking recess 211, preventing the locking protrusion 21 from being pulled out, ensuring a stable and reliable connection. When unlocking is required, the user presses both locking buttons 40 simultaneously. The locking spring 41 elastically deforms, causing the connecting latches 42 to disengage from the locking recess 211. At this time, the locking protrusion 21 can freely disengage from the main fastener 10, achieving quick unlocking.

[0028] In practical implementation, a first positioning protrusion 411 protrudes from one side of the locking spring 41, and a second positioning protrusion 412 protrudes from the other side of the locking spring 41. The first positioning protrusion 411 and the second positioning protrusion 412 are correspondingly arranged. When the user presses the locking button 40, the locking spring 41 undergoes elastic deformation, and the first positioning protrusion 411 and the second positioning protrusion 412 can slide relative to each other, ensuring that the locking button 40 moves smoothly in a preset direction and avoiding deviation or jamming.

[0029] In practical implementation, symmetrical positioning protrusions 113 are provided on both sides of the through groove 111, and a positioning groove 43 is provided between the two locking spring parts 41. The positioning protrusions 113 and the positioning groove 43 are positioned and connected to form a stable positioning connection structure. During use, when the user presses the locking button 40, the positioning groove 43 can slide along the positioning protrusion 113 to ensure the linear movement of the locking button 40 in the longitudinal direction and avoid lateral shaking or jamming.

[0030] In practical implementation, the first side fastener 20 is provided with a fastener block 22 on its side, and the lower surface of the second side fastener 30 is recessed with a fastener slot 31 that matches the fastener block 22. The surface of the fastener block 22 is recessed with a limiting groove 221, and the surface of the fastener slot 31 is protruded with a limiting protrusion 311 that matches the limiting groove 221. During assembly, the fastener block 22 is embedded in the fastener slot 31, and at the same time, the limiting protrusion 311 is embedded in the limiting groove 221 for connection, thereby correspondingly connecting the first side fastener 20 and the second side fastener 30. In use, a stable and detachable auxiliary connection is achieved between the first side fastener 20 and the second side fastener 30, further improving the overall structural strength and durability of the magnetic three-point safety buckle.

[0031] In practical implementation, the fastener block 22 is provided with a first reinforcing magnet 23 inside, the fastener slot 31 is provided with a second reinforcing magnet 32 ​​inside, and the inner surface of the locking groove 11 is provided with a third reinforcing magnet 12. In the assembled state, the first reinforcing magnet 23, the second reinforcing magnet 32 ​​and the third reinforcing magnet 12 are connected in sequence to form a magnetic attraction, so that the first side fastener 20 and the second side fastener 30 can be stably attracted to the main fastener 10, avoiding the fastener from loosening or misaligning due to vibration or external force.

[0032] In practical implementation, the upper end of the protruding post through the groove 111 is provided with a magnet mounting position 114, in which a first mating magnet 13 is installed, and a second mating magnet 24 is installed inside the locking protruding post 21. During the locking process, the first mating magnet 13 and the second mating magnet 24 form a magnetic attraction connection. This magnetic attraction structure not only plays a role in automatically guiding alignment during the initial insertion, but also provides additional attraction force after the lock is locked, effectively preventing the lock from accidentally disengaging due to external forces such as vibration and impact, thereby further improving the overall connection stability and safety of the three-point magnetic safety buckle.

[0033] In practical implementation, the locking groove 11 is covered with a fastener cover plate 14. The inner side of the locking groove 11 is evenly provided with several snap-fit ​​positions 115, and the inner side of the fastener cover plate 14 is evenly provided with several connecting snaps 141. Each connecting snap 141 corresponds one-to-one with a snap-fit ​​position 115. During assembly, the connecting snap 141 can be inserted into and locked into the snap-fit ​​position 115, achieving a stable and fixed connection between the fastener cover plate 14 and the locking groove 11. Simultaneously, this cover plate design facilitates user disassembly or replacement when needed, improving the convenience of product maintenance and the overall structural integrity.

[0034] In practical implementation, the main buckle 10 has a main strap connection position 15 on its side, the first side buckle 20 has a first side strap connection position 25 on one side, and the second side buckle 30 has a second side strap connection position 33 on one side. In use, the main strap connection position 15, the first side strap connection position 25 and the second side strap connection position 33 work together to stably connect the magnetic three-point safety buckle to the strap or other related accessories, ensuring the fastener's firmness and reliability in use.

[0035] In summary, the main fastener 10 has a first side fastener 20 connected to one side and a second side fastener 30 connected to the other side. The first side fastener 20 and the second side fastener 30 are correspondingly connected. The inner surface of the main fastener 10 is recessed with a locking groove 11. Locking buttons 40 are connected to the two sides of the locking groove 11. The side of the first side fastener 20 is provided with a locking protrusion 21. The middle of the locking groove 11 is provided with a protrusion through groove 111. The locking protrusion 21 is connected in the protrusion through groove 111. At the same time, the two locking buttons 40 are locked and fixed with the locking protrusion 21. The magnetic three-point safety buckle of this utility model improves the stability of the fastener through the three-point force distribution. The locking structure combines sliding positioning and elastic locking, which can realize quick locking and unlocking, effectively avoiding jamming caused by misoperation or pulling. The magnetic force enhances the connection stability and significantly improves the safety and durability during long-term use.
