[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, a high-hardness anti-shear padlock comprises: a lock body 1 and a lock beam 2, a raised block 201 is fixedly installed on the outer surface of the lock beam 2, a first drain groove 101 and a second drain groove 102 are respectively opened on the upper surface and both sides of the lock body 1, the first drain groove 101 and the second drain groove 102 are connected, a U-shaped block 3 is fixedly installed on the upper surface of the lock body 1, guide grooves 301 are opened on both sides of the inner ring wall of the U-shaped block 3, a closing component 4 is slidably installed in the guide groove 301, and the closing component 4 can fill the space in the lock beam 2 together with the U-shaped block 3, the lock body 1 and the lock beam 2 are made of alloy steel, chromium-gold elements are added to the alloy steel of the lock body 1 and the lock beam 2 to improve its anti-rust performance, the raised blocks 201 on the surface of the lock beam 2 are staggered left and right, and the four corners of the raised blocks 201 are chamfered.

[0022] In the above-mentioned design, the protruding blocks 201, the U-shaped block 3, the closing component 4, the first water-repellent groove 101 and the second water-repellent groove 102 are designed, and the protruding blocks 201 are staggered on the surface of the lock beam 2, and the staggered patterns of the protruding blocks 201 can increase the friction and resistance during sawing to reduce the sawing efficiency. When a saw or a tool tries to cut or shear the lock beam 2 with staggered patterns, it is necessary to cut the protruding blocks 201 in multiple directions at the same time, which applies more friction and shearing resistance to the sawing of the saw blade. Such increased friction and shearing resistance can make the sawing process more difficult, thereby prolonging the sawing time and increasing the force required for sawing, thereby increasing the anti-sawing performance of the lock beam 2;

[0023] The first hydrophobic groove 101 and the second hydrophobic groove 102 are provided on the surface of the lock body 1. When water droplets contact the surface of the lock body 1, the first hydrophobic groove 101 and the second hydrophobic groove 102 can quickly guide the water droplets and flow out along the grooves, thereby effectively preventing the water droplets from accumulating on the surface of the lock body 1.

[0024] At the same time, the first hydrophobic groove 101 and the second hydrophobic groove 102 help to quickly remove moisture from the surface of the lock body 1, thereby improving the waterproof performance of the lock, which helps to protect the mechanical parts and electronic components inside the lock and prevent damage or failure caused by moisture intrusion;

[0025] When the lock beam 2 is locked into the lock body 1, the U-shaped block 3 fixedly installed on the upper surface of the lock body 1 will fill the internal space of the lock beam 2, and the closing component 4 therein will adaptively slide downward in the guide groove 301 again according to the thickness of the locked object, and will fill the remaining space in the U-shaped block 3 again, which can maximize the reduction of the space in the U-shaped block 3 and avoid shearing caused by the insertion of a knife, thereby making it have a stronger anti-shear performance.

[0026] Furthermore, if Figure 4 As shown, the closing component 4 includes a guide block 402, which is slidably mounted on the outer surface of the sliding column in the guide groove 301, and a closing disk 401 is fixedly installed between the two groups of guide blocks 402. A semicircular opening 403 is opened on the upper surface of the closing disk 401, and the semicircular opening 403 can slide with the closing disk 401 to fit the upper end of the inner ring wall of the U-shaped block 3, and the semicircular opening 403 can form a circular opening between the U-shaped block 3, and a spring 302 is mounted on the outer surface of the sliding column in the guide groove 301, and the two ends of the spring 302 are respectively fixedly connected between the guide block 402 and the guide groove 301, and the closing disk 401 can be slidably received in the receiving groove 103 through the guide block 402, and the receiving groove 103 is opened on the upper surface of the lock body 1.

[0027] The above-mentioned design, through the design of the U-shaped block 3, the storage groove 103, the closing disk 401, the guide block 402 and the semicircular opening 403, when the lock beam 2 is locked into the lock body 1, the U-shaped block 3 fixedly installed on the upper surface of the lock body 1 will fill the internal space of the lock beam 2, and the closing disk 401 therein will adaptively slide downward in the guide groove 301 according to the thickness of the locked object, and at the same time, the closing disk 401 will press on one end of the spring 302, and the spring 302 will exert an upward elastic force on the closing disk 401, so that the closing disk 401 can fit tightly on the surface of the locked object, and at the same time, the closing disk 401 will fill the remaining space in the U-shaped block 3 again, which can maximize the reduction of the space in the U-shaped block 3, and can avoid the insertion of a tool and causing shearing, thereby making it have a stronger anti-shear performance; and the semicircular opening 403 on the upper surface of the closing disk 401 can form a circular opening with the U-shaped block 3 for the insertion of the locked rod.

Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
