Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] See attached picture. The nut provided by the embodiment of the present invention includes an upper nut 1 and a lower nut 2 that are fastened together and can rotate relative to each other.

[0036] The axial center positions of the upper nut 1 and the lower nut 2 are respectively provided with threaded hole 1 12 and threaded hole 2 22 of the same type, and the corresponding positions of the upper and lower nuts are respectively provided with opening groove 1 13 and opening groove 2 23. The widths of groove one and opening groove two are slightly larger than the outer diameters of threaded hole one and threaded hole two.

[0037] The upper and lower nuts are hexagonal nuts, and the opening slot 13 is opened from a side wall of the upper nut 1 and extends to the center to intersect with the threaded hole 12, and the central angle of the ...

Abstract

The invention discloses a nut and a mounting method thereof, and relates to the technical field of fixing parts. The nut comprises an upper nut body and a lower nut body which are buckled axially and which can rotate correspondingly. A screw I and a screw II in same specification are axially arranged at the center of the upper nut body and the lower nut body, corresponding positions of the upper nut body and the lower nut body are provided an open groove I and an open groove II which axially penetrate the upper nut body and the lower nut body, and the width of the open groove I and the open groove II are slightly larger than the large diameter of the screw I and the screw II. When the nut is mounted, the open groove I and the open groove II are allowed to be flush, the nut is clamped on a bolt through the open groove I and the open groove II, the upper nut body and the lower nut body are rotated to fix the nut on the bolt. The nut is reasonable in entire structure and convenient to rapid fix and mount, mounting efficiency is improved, the screwed nut has functions of locking and loss proofing, and mounting fixation is high. The mounting method of the nut is simple in steps and convenient to rapid complete operations, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a nut, and also to a method for installing the nut. Background technique [0002] Nuts are one of the more common fasteners. Objects can be fixed through the cooperation of nuts and bolts. After tightening, the threaded parts of the nuts and bolts are tightly pressed together depending on the elasticity of the nuts, bolts and the fasteners. , to generate friction, so as to complete the fastening installation of the fastened parts. When the static load and the working temperature change little, the connection between the nut and the bolt can be guaranteed to be self-locking and not loose. However, under the action of shock, vibration, load change, or high temperature and large temperature change, the connection between the nut and the bolt will become loose, or even loosen, which will affect the normal operation of the machine and cause the machine to have safety hazards. If ...
