[0028] Example 1

[0029] See also Figures 1 to 5The embodiment of the first aspect of the utility model provides a strong magnetic unlocking safety lock buckle structure, the lock buckle structure includes a male buckle 3, a female buckle 2 and a strong magnetic key, the female buckle 2 is provided with a magnetic lock structure, a receiving cavity is provided between the magnetic lock structure and the bottom of the female buckle 2, the male buckle 3 can be inserted into the receiving cavity, the magnetic lock structure is used to lock the male buckle 3, and the strong magnetic key is used to open the magnetic lock structure to pull the male buckle 3 out of the female buckle 2. In the female buckle 2, the plug buckle base plate 6 and the plug buckle upper cover plate 7 are connected by four fixing rivets 8 to form the outer shell of the female buckle 2. The male buckle 3 and the female buckle 2 mentioned above cooperate with each other to form a stable connection, the magnetic lock structure is used to further lock the male buckle 3, the strong magnetic key includes an external strong magnetic key 4 or a built-in strong magnetic key 5 of the safety belt, the strong magnetic key is used to open the magnetic lock structure so that the male buckle 3 can be pulled out of the female buckle 2, and the double locking structure is used to avoid the safety hazards of accidentally opening the plug buckle, and improve the connection stability and safety of the lock buckle structure.

[0030] The strong magnetic key in the strong magnetic unlocking safety lock buckle of the utility model adopts a combination of a sliding lock pin 14 and a lock pin groove 17. The sliding lock pin 14 is moved by the magnetic attraction of an external or built-in strong magnetic key 5 of the safety belt to open the strong magnetic unlocking safety lock buckle. The safety belt uses a strong magnetic unlocking anti-misopening function to ensure that the buckle will not be opened by mistake; the male buckle 3 and the female buckle 2 cooperate to provide a fastening connection and form multiple safety backups when the buckle is connected to the load-bearing webbing of the safety belt.

[0031] Optionally, the magnetic lock structure includes a lock pin sliding groove 13, a sliding lock pin 14 slidably connected to the lock pin sliding groove 13 is provided on the lock pin sliding groove 13, a first spring 15 is sleeved on the sliding lock pin 14, a limit plate is provided on the sliding lock pin 14 to make the first spring 15 in a compressed state, and the sliding lock pin 14 can move relative to the lock pin sliding groove 13. The lock pin sliding groove 13 is located at the buckle upper cover plate 7 of the female buckle 2 to form an integral structure therewith, the first spring 15 is placed between the lock pin sliding groove 13 and the sliding lock pin 14, the sliding lock pin 14 and the first spring 15 are enclosed in the lock pin sliding groove 13 by a lock pin hole plate 16, and the sliding lock pin 14 can slide slightly in the lock pin sliding groove 13.

[0032] Optionally, the magnetic lock structure further includes a lock pin hole plate 16, which is mounted on the bottom plate of the female buckle 2, and the sliding lock pin 14 partially extends into the lock pin hole plate 16. Under the push of the first spring 15, one end of the sliding lock pin 14 always extends out of the hole in the middle of the lock pin hole plate 16. Furthermore, the sliding lock pin 14 extending into the lock pin hole plate 16 is provided with an inclined surface. When the male buckle 3 is inserted into the female buckle 2, the sliding lock pin 14 forms an obstacle to the male buckle 3. The setting of the inclined surface makes it easier for the male buckle 3 to push the sliding lock pin 14 away and insert the male buckle 3 into the accommodating cavity of the female buckle 2. The sliding lock pin 14 moves downward again under the action of the first spring 15 and extends into the lock pin groove 17 in the male buckle 3 to limit and lock the male buckle 3.

[0033] Optionally, the sliding lock pin 14 is a magnetic metal cylindrical structure, and the strong magnetic key is placed outside the lock pin sliding groove 13 to attract the sliding lock pin 14, so that the sliding lock pin 14 moves in the direction of the lock pin sliding groove 13. The strong magnetic key and the sliding lock pin 14 are made of materials that have magnetic attraction to each other, and the strong magnetic key is used to move the sliding lock pin 14 in a direction away from the male buckle 3, so that the male buckle 3 can be pulled out from the female buckle 2 to open the safety lock buckle.

[0034] Optionally, the male buckle 3 is provided with a protrusion 18, and the protrusion 18 is provided with a locking pin groove 17, and the locking pin groove 17 cooperates with the sliding locking pin 14. The male buckle 3 cooperates with the female buckle 2, and a combination of a traditional bull horn switch 10 and a plug protrusion 18 is adopted to form a locking structure.

[0035] Optionally, the female buckle 2 is also provided with a horn switch 10, which is installed on the bottom plate of the female buckle 2 through a rivet 8. The horn switch 10 and the second spring 11 are fixed in the spring positioning groove 12 of the female buckle 2. A spacing is provided between the two horn switches 10 to form an insertion channel for the male buckle 3. Furthermore, the two horn switches 10 cooperate with the convex falcons 18 of the male buckle 3 to limit and lock the male buckle 3. By pressing the horn switch 10, the insertion channel of the male buckle 3 can be opened, and the male buckle 3 can be pulled out. After being released, the horn switch 10 is reset under the action of the second spring 11.

[0036] When the external strong magnetic key 4 or the built-in strong magnetic key 5 of the safety belt 1 is not used to unlock, the load-bearing webbings of the safety belt 1 will not be separated and opened by mistake. When the two symmetrically arranged bull horn switches 10 clamp the convex dove 18 at the front end of the male buckle 3, it can provide a very large connection strength for the buckle. When the male buckle 3 enters the inside of the female buckle 2 and reaches the correct position, the sliding lock pin 14 pushed by the lock pin spring extends out of the lock pin hole plate 16 and enters the lock pin groove 17, which can prevent the male buckle 3 from being separated from the female buckle 2 by mistake. When in use, only after the external strong magnetic key 4 or the built-in strong magnetic key 5 of the safety belt 1 attracts the sliding lock pin 14 to retract into the lock pin hole plate 16, the sliding lock pin 14 can leave the lock pin groove 17. At this time, the bull horn switches 10 are pressed on both sides of the female buckle 2 at the same time, so that the gap between the two bull horn switches 10 is larger than the width of the convex dove 18 at the front end of the male buckle 3, and the male buckle 3 can withdraw from the female buckle 2 part. When no external force is applied to the movable parts of the buckle or the external strong magnetic key 4 and the built-in strong magnetic key 5 of the seat belt 1 are used, the movable parts at various locations always maintain their original state under the push of their respective reset springs. This state can ensure the tight connection between the male buckle 3 and the female buckle 2.

[0037] Furthermore, both the male buckle 3 and the female buckle 2 are provided with a webbing connection hole 9. The webbing connection hole 9 is used to connect with the safety belt 1, and the male buckle 3 is also provided with a webbing pressure plate 19.

The safety belt 1 has a locking structure of a male buckle 3 and a female buckle 2 for transmission, and a magnetic lock structure is arranged on the female buckle 2. The magnetic lock structure is first opened by a strong magnetic key, and then the male buckle 3 and the female buckle 2 can be separated, forming a double protection, avoiding accidental operation to open the safety buckle, and improving the safety performance of the use of the safety belt 1.
