Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a strong hoop bolt, as shown in fig. 1 to 3, which comprises a bolt head 1 and a stud 2, wherein a locking nut 3 is connected to the stud 2 in a threaded manner.

The tail end of the stud 2 is provided with a connecting groove 21, the connecting groove 21 is connected with a connecting column 4 in a threaded manner, a protective sleeve 5 is fixed on the connecting column 4, and the protective sleeve 5 is sleeved on the outer side of the stud 2. Two placing grooves 51 are circumferentially and uniformly distributed on the outer side of the protective sleeve 5, a pull groove 52 is formed in the side wall of each placing groove 51, a positioning column 53 is fixed in each placing groove 51, a rotating rod 54 is arranged in each placing groove 51, an adjusting groove 55 for allowing the positioning column 53 to slide is formed in each rotating rod 54, a limiting groove 56 corresponding to the positioning column 53 in position is formed in the bottom of each placing groove 51, each rotating rod 54 is made of a magnetic material, and positioning magnets 57 are arranged at the bottoms of the placing grooves 51 and the limiting grooves 56.

When installing the bolt, lock the clamp through lock nut 3, then upset rotary rod 5490 degrees just slide rotary rod 54 to spacing groove 56 in, can rotate protective sheath 5 and spliced pole 4 through rotary rod 54, with spliced pole 4 and the cooperation of spread groove 21, and make protective sheath 5 and lock bolt butt, so can accomplish the installation of bolt, the afterbody of bolt has received the sheltering from of protective sheath 5 this moment, make the bolt be difficult for receiving the corruption, be convenient for people's later stage pull down lock nut 3, make the bolt dismantle convenient, easily people use, and through the extrusion of protective sheath 5 to lock nut 3, make lock nut 3 fix a position more firmly, be convenient for lock the bolt.
