[0024] See also Figure 1-6 A high-strength anti-saw padlock comprises a lock body 1, a fastener 2 is arranged on the lock body 1, a protective seat 5 for protecting the fastener 2 is fixedly installed on the top of the lock body 1, a placement groove 16 is reserved in the protective seat 5, the fastener 2 is arranged in the placement groove 16, a mounting seat 11 for protecting the fastener 2 is fixedly installed on the top of the protective seat 5, an anti-saw mechanism for preventing the fastener 2 from being sawed is arranged in the mounting seat 11, a first protective block 3 and a second protective block 4 are arranged on both sides of the top of the lock body 1, and the fastener 2 is arranged between the first protective block 3 and the second protective block 4.

[0025] It is worth noting that, in the above design, an escape passage 7 is left between the first protective block 3 and the protective seat 5, so that when the padlock is opened, the fastener 2 can be easily rotated and moved out of the escape passage 7.

[0026] Furthermore, the anti-saw mechanism includes a bracket 14, a support block 13 and a rotating wheel 15. The mounting seat 11 is provided with a mounting groove 12, the support block 13 is fixedly connected to the inner wall of the mounting groove 12, the bracket 14 is fixedly connected to the mounting seat 11 and the support block 13, and the rotating wheel 15 is movably mounted on the bracket 14. With the above design, the bracket 14 can be supported and fixed by the support block 13, and the mounting seat 11 can be protected by the rotating wheel 15 when the mounting seat 11 is damaged by lawbreakers.

[0027] Specifically, when criminals saw off the fastener 2, the rotating wheel 15 will rotate on the bracket 14 when being sawed, making it difficult for the saw to saw off the rotating wheel 15, thereby playing an anti-saw role.

[0028] Furthermore, a protective column 10 is fixedly connected to the side of the protective seat 5, and a through hole 8 is opened in the protective column 10, and one end of the fastener 2 is inserted into the through hole 8. According to the above design, the fastener 2 can be protected by the protective column 10, and the safety of the fastener 2 can be improved when the fastener 2 is damaged by lawless elements.

[0029] Furthermore, two groups of positioning blocks 21 are symmetrically arranged at the bottom of the protection seat 5, and a positioning groove 22 for positioning the protection seat 5 is opened at the top of the lock body 1. The positioning blocks 21 are inserted into the positioning grooves 22, and the protection seat 5 is fixedly installed on the top of the lock body 1 by fixing screws 6. The above design, through the positioning blocks 21 inserted into the positioning grooves 22, can facilitate the positioning of the protection seat 5 during installation, and at the same time, it can be convenient to replace the protection seat 5 after the protection seat 5 is damaged; the fixing screws 6 are installed from the inner bottom of the placement groove 16, so that after the padlock is used, the fastener 2 can be placed inside the placement groove 16, and the fastener 2 placed in the placement groove 16 can cover the fixing screws 6, thereby preventing lawless elements from disassembling the protection seat 5 from the outside.

[0030] Specifically, by cooperating with the protective seat 5, the first protective block 3, the second protective block 4, the arc-shaped reinforcement block 9 and the mounting seat 11, the purpose of preventing the fastener 2 from being sawed can be achieved, and the anti-shearing performance of the fastener 2 can be provided, thereby improving the safety of the fastener 2.

[0031] Furthermore, the bottom of the mounting seat 11 is fixedly connected with an insert block 17, the top of the protection seat 5 is provided with a slot 18, the insert block 17 is inserted into the slot 18, a mounting hole 19 is provided on the insert block 17, the side of the protection seat 5 is provided with a mounting screw 20, the threaded end of the mounting screw 20 passes through the mounting hole 19, and the mounting seat 11 is fixedly mounted on the protection seat 5 through the insert block 17 and the mounting screw 20. In the above design, the mounting seat 11 is fixedly mounted on the protection seat 5 through the insert block 17 and the mounting screw 20, so that the mounting seat 11 can be easily disassembled and replaced after the rotating wheel 15 is damaged by the saw. The mounting screw 20 is arranged on the inner side of the protection seat 5, so as to prevent the installation seat 11 from being disassembled from the outside by lawless elements, and improve the installation performance of the protection seat 5 after installation.

[0032] Furthermore, an arc-shaped reinforcement block 9 is fixedly connected to the upper surface of the fastener 2. The above design can improve the strength of the fastener 2 through the arc-shaped reinforcement block 9, and can also protect the fastener 2, making it difficult for lawless elements to try to damage the padlock.

[0033] In specific use, after the padlock is opened, the fastener 2 is dragged to move one end of the fastener 2 out of the protection column 10. After one end of the fastener 2 is moved out of the protection column 10, the fastener 2 is rotated so that the fastener 2 can be easily rotated out of the avoidance channel 7.

[0034] After the padlock is used, the fastener 2 will be locked in the lock body 1, and one end of the fastener 2 will pass through the through hole 8 and be placed inside the protective column 10. The fastener 2 can be placed inside the placement groove 16. Through the cooperation of the protective seat 5, the first protective block 3, the second protective block 4, the arc-shaped reinforcement block 9 and the mounting seat 11, the anti-saw purpose of the fastener 2 can be achieved, and the anti-shear performance of the fastener 2 can be provided to improve the safety of the fastener 2. When the fastener 2 is sawed by criminals, the rotating wheel 15 will rotate on the bracket 14 when it is sawed, making it inconvenient for the saw to saw the rotating wheel 15, thereby playing an anti-saw role.
