A self-locking nut is formed with a rear nut body with internal threading and a front nut body having circumferentially arranged, crush-locking lips provided on a forward contact face of the front nut body and being spaced from the internal threading of the rear nut body by an internal relief cut for accommodating deformation of the crush-locking lips therein. When the nut is tightened down on an object on a fastener bolt, the crush-locking lips are forced inwardly and deformed on the threaded shaft of the fastener bolt into the space of the internal relief cut in order to form a permanent lock on the fastener bolt. In another preferred embodiment, the self-locking nut has a front “flying saucer” shaped part configured to work like a “jam nut” portion, and a rear “nut body” part having a front indentation space configured to work like an inner relief cut. The two parts are joined together by circumferential welding and flattening of the “flying saucer” part into the inner relief cut space of the “nut body” part while leaving a small gap between the parts.

A self-locking nut includes a main-nut body and a deformable-nut body. The main-nut body has a recess leading into an interior threaded bore forming x turns of an internal thread therein. The deformable-nut body has an outer flange and an interior threaded bore forming y turns of an internal thread therein. The outer flange of the deformable-nut body is fixed to the main-nut body such that a relief space is formed between the deformable-nut body and the recess. A ratio of x:y is about 2:1.

A one-piece, self-locking nut is formed with a threaded nut body integrally formed with crush-locking lips on a forward contact face of the nut body spaced by an internal relief cut for accommodating deformation of the crush-locking lips therein. When the nut is tightened down on an object on a fastener bolt, the crush-locking lips are forced inwardly and deformed on the threaded shaft of the fastener bolt into the space of the internal relief cut in order to form a permanent lock on the fastener bolt. The one-piece, self-locking nut can be fabricated by conventional nut manufacturing methods. In use it threads on quickly like a conventional nut and installs with conventional tools.

A hanging wire post with a locking connector for decorative hanging applications. This hanging wire post would be alternate to using eyelets or D-rings for attachment point of hanging wire to frame. This hanging post will install to frame with a single center-point screw. This post supports the hanging wire which is threaded through and around backside of post resulting in a frictional grip on wire that facilitates wire length adjustment. The hanging wire is then locked into position with the parallel line locking connector. The result is a very high strength end connection, and very quick and precise installation. No frustration of trying to tie precise knots in stranded wire or stranded wire rope. This device will work equally well with coated or uncoated stranded wire and wire rope.

The invention discloses a wire drawing machine and relates to the technical field of cable machining. The wire drawing machine comprises a machine shell and a machine cover; one inner wall of the machine shell is provided with two sliding bases in a relative sliding manner; a conical roller is fixed to one side of each sliding base; the outer wall of the machine shell is provided with an adjustingassembly; a lower supporting rod with a wire drawing lower mold is obliquely arranged on the inner wall of the machine shell and an upper supporting rod with a wire drawing upper mold is arranged onthe inner wall of the machine shell in a lifting manner; the two ends of the machine shell are provided with a wire inlet and a wire outlet correspondingly; a material guiding box is fixed to the end,at the wire inlet, of the outer wall of the machine shell; and two wire guiding rollers are rotationally arranged in the material guiding box. A small amount of copper wire is wound on the peripheralsides of the two conical rollers; the two sliding bases are adjusted to make the sliding bases move deviating from each other so that the copper wire can be tightened and stretched; the copper wire can be clamped through the wire drawing upper mold and the wire drawing lower mold; and after normal work, it is only needed to remove the part of copper wire. Due to the wire drawing machine, the interval of the two conical rollers can be adjusted, and therefore wire winding of the copper wire is facilitated, fast wire penetrating of the copper wire is achieved, the feeding efficiency of the copper wire is improved, and operation is easy, convenient and fast.
