DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A wind power anti-theft fastener comprises a threaded rod 1, the outer surfaces of the threaded rod 1 are respectively threadedly connected with a fastening nut 3 and an anti-theft wrapping block 4, the inner wall of the anti-theft wrapping block 4 is threadedly connected with three sets of jacking bolts 9, the bottom end of each set of jacking bolts 9 contacts the top end of the fastening nut 3, the outer surface of the connecting plate 6 is fixedly connected with an anti-skid sleeve 17, the outer surface of the anti-skid sleeve 17 is fixedly connected with a plurality of identical anti-skid rubber columns 18, by providing the anti-skid rubber columns 18, the friction force of the outer surface of the anti-skid sleeve 17 can be increased, by providing the anti-skid sleeve 17 and the anti-skid rubber columns 18, the friction force of the outer surface of the connecting plate 6 can be jointly increased, so as to facilitate the hand-holding of the connecting plate 6, thereby facilitating the hand-holding of the connecting plate 6 to move and carry it.

[0024] A connecting plate 6 is provided above the anti-theft package block 4, and three groups of clamping blocks 7 are fixedly connected to the bottom surface of the connecting plate 6. The outer surface of each group of tightening bolts 9 is sleeved with two gaskets 14, and the outer surface of each gasket 14 contacts the inner wall of the anti-theft package block 4. There is a certain groove space inside the bottom surface of the connecting plate 6 to facilitate the accommodation of the top end of the longer threaded rod 1 and avoid direct contact between the top end of the threaded rod 1 and the connecting plate 6. The corresponding length of the clamping block 7 is selected according to the relative position of the threaded rod 1 and the fastening nut 3 after tightening and installation. By providing a gasket 14, it can be padded between the anti-theft package block 4 and the tightening bolt 9, thereby increasing the contact area between the two and increasing the relative stability of the two.

[0025] The upper surface of the connecting disk 6 is fixedly connected to the docking rod 8, and three groups of soft blocking blocks 16 are clamped inside the anti-theft package block 4. The upper surface of each group of soft blocking blocks 16 is fixedly connected to two limiting rubber disks 15. The outer surface of each limiting rubber disk 15 contacts the inner wall of the anti-theft package block 4. By providing the limiting rubber disk 15, the soft blocking blocks 16 can be prevented from being stuck in the anti-theft package block 4 and difficult to pull out. By providing the soft blocking blocks 16, they can be blocked above the tightening bolts 9 in the anti-theft package block 4, thereby hiding the tightening bolts 9 and increasing the anti-theft effect.

[0026] The outer surface of the anti-theft wrapping block 4 is provided with three groups of slots 5, and the interior of each group of slots 5 is snap-fitted with the outer surface of the block 7. The bottom surface of the anti-theft wrapping block 4 is fixedly connected with an anti-skid rubber ring 12, and the bottom end of the fastening nut 3 is fixedly connected with a plurality of identical first anti-skid steel bosses 13. The relative position of the slots 5 and the block 7 for mutual snap-fitting is selected according to the relative position of the threaded rod 1 and the fastening nut 3 after being fastened and installed. By providing the anti-skid rubber ring 12, the friction force of the bottom surface of the anti-theft wrapping block 4 can be increased, thereby increasing the stability of the anti-theft wrapping block 4 after the anti-theft wrapping block 4 is tightly pressed against the outer surface of the structure to be fastened. By providing the first anti-skid steel boss 13, the friction force of the bottom end of the fastening nut 3 can be increased, thereby increasing the stability of the fastening nut 3 after the bottom end of the fastening nut 3 is tightly pressed against the outer surface of the structure to be fastened.

[0027] The bottom end of the threaded rod 1 is fixedly connected to a limiting round head 2, and the outer surface of the threaded rod 1 is sleeved with a pad 10, and the upper surface of the pad 10 is fixedly connected to a plurality of identical second anti-slip steel bosses 11. By providing the second anti-slip steel bosses 11, the friction force on the upper surface of the pad 10 can be increased. By providing the pad 10, the contact area between the limiting round head 2 and the outer surface of the fastened structure can be increased, thereby increasing the relative stability between the two after the fastened connection.

[0028] The working principle of the utility model is as follows: when in use, a threaded rod 1 of appropriate length is selected according to the thickness of the structure to be fastened to pass through the interior of all the structures to be fastened, and after the pad 10 is put on the threaded rod 1, the pad 10 and the second anti-skid steel boss 11 are placed between the limiting round head 2 and the fastening structure, and then the part of the threaded rod 1 extending out of the structure to be fastened is threadedly connected to the fastening nut 3, and the first anti-skid steel boss 13 on the bottom surface of the fastening nut 3 is tightly pressed against the outer surface of the structure to be fastened, and then the anti-theft package block 4 is first manually held to thread the anti-theft package block 4 with the threaded rod 1, and then the electric drill is used to dock with the docking rod 8, and the card block 7 on the connecting plate 6 is inserted into the card slot 5 on the anti-theft package block 4, and then the power of the electric drill is used to make the anti-skid rubber ring 12 on the bottom surface of the anti-theft package block 4 press against the outer surface of the structure to be fastened. At this time, the anti-theft package block 4 The wrapping block 4 completely wraps the fastening nut 3 but does not contact the fastening nut 3. Then the block 7 on the connecting plate 6 is pulled out of the inside of the slot 5. Then, the six tightening bolts 9 are threadedly connected with the gasket 14 to the anti-theft wrapping block 4 so that the bottom end of each tightening bolt 9 presses against the top of the fastening nut 3. Finally, a combination of a limiting rubber disc 15 and a soft blocking block 16 is stuffed on the top of each tightening bolt 9 inside the anti-theft wrapping block 4. In this way, the fastening nut 3 is completely detached from the threaded rod 1. In addition to the complicated process, the corresponding connecting plate 6, block 7, docking rod 8 and slot 5 combination are also required. This increases the anti-theft effect of the entire fastener. The design of the entire wind power anti-theft fastener effectively solves the problem of easy removal by conventional tools and the risk of theft due to the lack of a complex and reliable anti-theft structure.
