Description

Technical Field

[0002] Bolts are a commonly used fastener used to fix and connect devices between bolts and nuts. During the installation of steel structures, bolts are generally used for fixing.

[0003] However, most of the current steel structures are fixed with bolts directly by nuts. When external force vibrates the steel structure, the nuts will rotate and may separate from the bolts, causing the bolts to fall off, thus affecting the overall stability and safety of the steel structure.

[0004] The nut is threadably connected to the bolt rod, and the end of the bolt rod away from the bolt head is fixedly connected to a connecting rod. A fixing groove is provided in the connecting rod, and an internal thread is provided in the fixing groove. A limiting rod is threadably connected to the limiting rod in the fixing groove. The fixing rod is rotatably connected to the fixing rod in the fixing groove. The fixing rod can be slidably arranged in the fixing groove, and a clearance groove corresponding to the fixing rod is provided at one end of the bolt rod, and one end of the fixing rod can be extended into the clearance groove. An annular groove is provided on the side wall of the fixing rod. The utility model controls the fixing plate to extend out of the through groove by moving the fixing rod left and right, and plays a role of blocking the nut through the fixing plate, thereby preventing the nut from falling off the bolt, which is more tightened and safe.

[0005] Although the above patent can prevent the nut from falling off the bolt, making it more secure and safer, the device lacks a rainproof structure when in use. Bolts exposed to a humid environment for a long time will gradually lose strength and durability, thereby shortening their service life.
