Description

Anti-loosening T-shaped bolt Technical Field The utility model belongs to the technical field of fasteners, and particularly relates to an anti-loosening T-shaped bolt. Background The T-shaped bolt can be placed in an aluminum profile groove and is often matched with a flange nut, so that the T-shaped bolt is a standard matched connecting piece for mounting corner fittings, can be selected for use according to the width of the profile groove and different series of profiles, belongs to movable foundation bolts and is wide in application range. In the use process of the existing T-shaped bolt, because the nut of the T-shaped bolt lacks a limiting structure, when the mounting part provided with the T-shaped bolt vibrates, the T-shaped bolt is easy to rotate, so that the T-shaped bolt is easy to loosen and fall off, and therefore, the anti-loosening T-shaped bolt is required to be provided for solving the problems. Disclosure of utility model The utility model aims to provide a locking T-shaped bolt for solving the defects of the technology. The utility model provides a locking type T-shaped bolt, which comprises a T-shaped bolt, wherein the T-shaped bolt comprises a bolt head and a screw rod which are connected with each other, a threaded section and a non-threaded section are arranged on the screw rod, the non-threaded section is arranged close to the bolt head, a cavity is arranged in the non-threaded section and is cylindrical, two through holes are formed in the non-threaded section and are communicated with the cavity, a fixed plate and a movable plate are arranged in the through holes, a bearing hole is formed in the movable plate, a locking nail is fixedly arranged in the bearing hole, a communication hole matched with the locking nail to move is formed in the fixed plate, a spring is arranged between the movable plate and the fixed plate and is sleeved outside the locking nail, one end of the locking nail is arc-shaped and is positioned in the cavity, the other end of the locking nail is a tip, a rotating column is arranged in the cavity, the cross section of the rotating column is oval, a connecting rod is arranged on the rotating column, the bolt head and the non-threaded section are internally provided with mutually communicated through channels, the through channels are communicated with the cavity, the cross grooves are formed in the bolt head, the middle parts of the cross grooves are mutually communicated with the through channels, a rotating rod is arranged in the cross grooves, the cross grooves are upwards penetrate through the through channels, a rotating rod is fixedly connected with the through channels, and is fixedly connected through the cross rotating rod, and is arranged on the rotating rod.
