DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0024] This embodiment comprises five main parts: a housing, a lock mechanism 5, a U-shaped lock bar 8, an unlocking mechanism 11, and a locking bolt mechanism 12. The housing comprises symmetrical housings A1 and B2. Two pins 3 are symmetrically fixed to the right side of housing A1. These pins 3 are welded to housing A1 and serve to articulate the U-shaped lock bar 8. A slot 4 is provided in the center of the left side of housing B2. The lock mechanism 5 is located between housings A1 and B2. A hollow space is provided within the lock mechanism 5 to house the unlocking mechanism 11 and locking bolt mechanism 12.

[0025] Rotation slots 6 are symmetrically arranged on the upper and lower surfaces of the right side of the lock body 5. Rotation slots 6 are arc-shaped grooves. A placement slot 7 is symmetrically arranged on the upper and lower surfaces of the left side of the lock body 5. The placement slot 7 matches the shape of the left end of a U-shaped locking rod 8. Rotation slots 6 and placement slots 7 are used to accommodate the right and left ends of the U-shaped locking rod 8, respectively. This embodiment is a double-buckle safety lock, comprising two symmetrical U-shaped locking rods 8. Pin holes 9 are provided at the right ends of the U-shaped locking rods 8. The upper and lower U-shaped locking rods 8 are hingedly connected to the upper and lower pins 3 on the housing A1 through the pin holes 9 at their right ends. The right ends of the U-shaped locking rods 8 are positioned within the rotation slot 6, allowing them to rotate about the pin 3 within the rotation slot 6. The left ends of the U-shaped locking rods 8 are positioned within the placement slot 7. Upon rotation, the left end of the U-shaped locking rod 8 can be withdrawn from the placement slot 7. A locking slot 10 is provided on the inner side of the left end of the U-shaped locking rod 8. A lock tongue 13 extends into the locking slot 10 to lock the U-shaped locking rod 8.

[0026] A symmetrical, upper and lower locking bolt mechanism 12 is positioned within the lock body 5, forming a "down" shape. The bolt mechanism 12 comprises a horizontal bolt body 13, which is vertically attached to a drive plate 14. A horizontal fixing rod A15 is positioned to the right of the fixing rod 14. The left end of the bolt body 13 is shaped to match the locking groove 10. The lock body 5 is provided with a bolt slide 16, which allows the bolt body 13 to slide left and right. The bolt body 13 slides left and right within the bolt slide 16, locking and unlocking the U-shaped locking rod 8. A horizontal spring 17 is sleeved to the right of the fixing rod A15. A spring slide 18 is provided within the lock body 5, with a horizontal fixing rod B19 secured to its right end. The right end of the spring 17 is sleeved onto fixing rod B19, which corresponds to and is aligned with fixing rod A15. Spring 17 is located within spring chute 18. Spring chute 18, fixed rods A15, and B19 constrain spring 17, allowing it to extend and retract within chute 18 and on fixed rods A15 and B19. When bolt body 13 is within locking groove 10, spring 17 is slightly compressed. This further compresses spring 17 during unlocking, providing greater resilience and enabling it to return to its initial state more quickly and effectively. High-strength spring 17 is crucial to ensure reliable locking.

[0027] The unlocking mechanism 11 comprises a connecting rod 20, integrally formed with a right-facing curved push rod 21. In this embodiment, the curved push rod 21 is semicircular in shape. A push pin 22 is provided at the left end of the connecting rod 20, extending outward perpendicularly from the connecting rod 20. The outer end of the push pin 22 has a circular, enlarged portion. A sliding groove 23 corresponding to the slot 4 is provided on the left side of the lock body 5. The connecting rod 20 is positioned within the sliding groove 23, while the push pin 22 extends perpendicularly from the housing B2 and out of the slot 4. A circular hollow portion 24 is provided in the center of the lock body 5 for the curved push rod 21 to move left and right. The upper and lower ends of the curved push rod 21 abut against the drive plates 14 of the upper and lower latch mechanisms 12, respectively. By moving the circular enlarged portion of the push pin along the slot 4, the unlocking mechanism 11 moves left and right, thereby driving the latch mechanism 12 left and right via the drive plate 14, causing the left end of the latch mechanism 12 to extend into or out of the locking slot 10 of the U-shaped lock bar 8, thereby locking or unlocking the lock.

[0028] When in use, the operator wears the safety belt, then pushes the push pin 22 to the right to compress the spring 17, and the lock tongue body 13 slides to the right in the lock tongue slide 16, and the lock tongue body 13 leaves the locking groove 10 of the U-shaped lock rod 8. At this time, the upper and lower U-shaped lock rods 8 can be opened simultaneously, and the safety belt loop rope is passed through one of the U-shaped lock rods 8. The other U-shaped lock rod 8 is connected to a reliable fixed point, and then the upper and lower U-shaped lock rods 8 are closed. The push pin 22 is released. The compression force of the spring 17 pushes the lock tongue body 13 to slide to the left and enters the locking groove 10 again to lock the two U-shaped lock rods 8. At this time, the push pin 22 returns to its original position, i.e., at the leftmost end of the slot 4. After the U-shaped lock rod 8 is locked, the various parts of the safety belt are pulled hard again to check whether they are firm and reliable, and then the operation construction is carried out. The operator is connected to a U-shaped lock rod 8 of the present invention by the safety rope of his own safety belt, and the other U-shaped lock rod 8 is connected to a reliable fixed point, thereby ensuring safety.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
