Preferably, the top of the annular baffle plate is radially provided with an annular convex edge, the annular convex edge is protruded out of the top surface of the nut main body, a plurality of clamping grooves are formed in the annular convex edge, and a clamping block for fixing the clamping grooves is arranged on the nut main body.
Preferably, the locking block is a wedge block, and the small head of the wedge block is arranged towards the threaded hole.
Preferably, a self-locking button is arranged at the top of the nut main body, and a clamping block is fixed at the top of the self-locking button.
Preferably, the fixing column is in threaded installation with the locking hole.
Preferably, a flange is provided at the bottom of the nut body.
The utility model has the beneficial effects that: when the nut is installed, the locking block is blocked by the annular baffle plate, so that the nut and the bolt can be conveniently installed in a threaded mode, and after the installation is finished, the locking block locks the bolt to prevent the nut from falling off; the annular baffle is rotated by the annular convex edge at the top, and then the annular convex edge is fixed by the clamping block to prevent the annular convex edge from rotating.
The features and advantages of the present utility model will be described in detail by way of example with reference to the accompanying drawings.
