[ detailed description ] embodiments
Referring to fig. 1 to 4, the anti-seize tunnel resin anchor rod nut of the present invention comprises a nut body 1 and a plastic damping member 2, wherein the nut body 1 comprises a hexagonal section 11 and a circular plate section 12 located at one end of the hexagonal section 11, a threaded hole 13 is formed through the hexagonal section 11 and the circular plate section 12, an annular groove 111 is formed in the other end of the hexagonal section 11, the plastic damping member 2 is bonded in the annular groove 111 by injection molding and blocks the threaded hole 13, a plurality of channels 112 extending to the circular plate section 12 are formed on the annular groove 111, the hexagonal section 11 and the circular plate section 12 are of an integrated structure, the width of the hexagonal section 11 is smaller than the diameter of the circular plate section 12, a plurality of grooves 121 are formed on the end surface of the other end of the circular plate section 12, the diameter of the annular groove 111 is larger than the diameter of the threaded hole 13, and a step is formed between the annular groove 111 and the threaded, the outlet of the channel 112 is located on the step, the inner wall of the annular groove 111 is provided with a plurality of rotation stopping protrusions 113, the channel 112 is symmetrical about the center of the nut body 1, one side of the plastic damping part 2, which is far away from the circular plate section 12, is provided with a recess 21, one side of the plastic damping part 2, which is close to the circular plate section 12, is provided with a conical protrusion 22, and the center of the conical protrusion 22 is located at the axis of the nut body 1 and is in point contact with the end part of the screwed-in anchor rod.
The working process of the invention is as follows:
