[0002] Commonly used bolts and nuts are essential components for connecting mechanical parts and securing devices. They are convenient to use, easy to install and remove, but their safety is crucial for infrastructure located outdoors, such as railways, highway bridges, transmission towers, and microwave communication towers. Because they can be easily removed, they are often targeted by criminals for theft or vandalism, creating significant safety risks or even causing direct damage to these infrastructures.

[0003] Chinese utility model patent publication number CN203384195U discloses an anti-theft bolt assembly. The anti-theft bolt assembly includes: a bolt body, including a bolt head and a screw nut, which cooperates with the screw of the bolt body; a sleeve, which includes a barrel, and at least one of the bolt head and the nut is provided with a sleeve, and the bolt head or nut, which is provided to cooperate with the sleeve, is disposed within the barrel of the sleeve;

[0004] In the above-mentioned anti-theft bolt assembly, the sleeve covers the bolt head and the nut when in use. After the sleeve is removed, the bolt head can be pulled out, and the anti-theft effect is poor. To this end, we provide a bolt with an anti-theft structure to remedy the above-mentioned problem. The baffle is locked by the buckle at the bottom. The baffle and the buckle have a double-layer clamping effect to prevent the main bolt from being removed, and the anti-theft effect is improved to a certain extent. Utility Model Content

[0008] As a further technical solution of the present invention, the four baffles are fitted and connected to the bottom of the baffle bin.

[0009] As a further technical solution of the present invention, a circular hole is opened on each of the four baffles, and a baffle rod is set in each of the four circular holes. The four baffle rods pass through the bottom of the baffle bin and are welded to the top plate.

[0010] As a further technical solution of the present invention, the top plate is circular in shape, and the four baffle rods on the top plate are evenly distributed, and the top plate is fitted and connected to the bottom of the baffle bin.

[0011] As a further technical solution of the present invention, a rectangular opening is provided on each of the four baffles, and the rectangular openings are respectively engaged with corresponding clips. There are four clips, and the other ends of the four clips are welded to the clip fixing plate.

[0012] As a further technical solution of the present invention, the buckle fixing plate is circular, and the diameter of the buckle fixing plate is larger than the diameter of the baffle compartment.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] According to the utility model, the main bolt is connected to the position to be fixed, and after tightening, the other side of the main bolt is exposed, and the top plate is pulled out. At this time, the spring will extend outward, thereby driving the blocking piece to pop out, and its length is greater than the diameter of the main bolt. Then the top plate is inserted, and the blocking rod on the top plate will be clamped in the gap of the spring to prevent the blocking piece from moving back. When the buckle on the buckle fixing plate is clamped into the rectangular opening of the blocking piece, the blocking piece and the buckle are locked, and the buckle cannot be taken out. At the same time, the blocking piece cannot be retracted inward under the obstruction of the blocking rod and cannot be disassembled, thereby ensuring the anti-theft effect of the bolt.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 In an embodiment of the utility model, a bolt with an anti-theft structure includes a main bolt 4. A baffle bin 1 is provided at the bottom of the main bolt 4. The baffle bin 1 is hollow. A fixing bar 6 is provided on the inner side of the baffle bin 1. There are four fixing bars 6 in total, and the four fixing bars 6 are evenly distributed at the bottom of the baffle bin 1. A spring 7 is welded on each of the four fixing bars 6, and the other end of each of the four springs 7 is connected to a baffle 5.

[0021] In this embodiment, the four baffles 5 are closely connected to the bottom of the baffle compartment 1 .

[0022] In this embodiment, a circular hole is opened on each of the four baffles 5 , and a baffle rod 8 is provided in each of the four circular holes. The four baffle rods 8 pass through the bottom of the baffle bin 1 , and the four baffle rods 8 are welded to the top plate 9 .
