Abstract

The invention provides a double-thread nut and a preparation method process thereof. The double-thread nut comprises a hexagonal nut. A spherical nut is welded to the hexagonal nut. The upper end of the spherical nut is provided with a first connecting hole. A pipe sleeve is detachably connected to the inner side of the first connecting hole. An inner port of the pipe sleeve is provided with a thread structure. According to the double-thread nut, the hexagonal nut and the spherical nut are combined, the lower end of the double-thread nut is provided with a first thread in a tapping mode, the upper portion of the spherical nut is provided with the first connecting hole, the first connecting hole can be provided with a second thread as required or the pipe sleeve is arranged in the first connecting hole, the inner wall of the pipe sleeve is provided with the second thread, and thus, the double-thread nut is convenient to install.

Description

technical field [0001] The invention relates to the technical field of nut preparation, and mainly relates to a double-thread nut and a preparation process thereof. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. A component that must be used in all manufacturing machinery is divided into carbon steel, stainless steel, and non-ferrous metals (such as copper) according to different materials. several types. [0003] The existing nut is convenient to use by setting the inner center as a thread, and then setting the outer part into a corresponding shape according to requirements. [0004] However, nowadays people want to use the nuts for the feet of the handrails of the stairs for corresponding use, so that the nuts are connected with the handrail nuts, and then the nuts are connected with the screws on the ground, so that it is easy to operate and convenient for later replacement, so this The operation, that...
