Problems solved by technology

However, since most of the railways are unattended, the method of using hex nuts to fix the rails is prone to man-made damage and theft, which undoubtedly poses a serious threat to railway safety; in addition, due to the exposed fasteners, it is easy to Affected by the harsh environment of sun and rain for a long time, it will produce embroidery and reduce the service life, which will also threaten the safety of railway use

Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings: the present invention is mainly made up of the nut body 1 that is internally threaded and the cap 2 that its top links to each other. The shape of the nut body 1 is that three short cones 3 are stacked up and down successively to form an axial end face with a stepped shape, and each short cone is respectively formed with three oblique cut surfaces 4 uniformly distributed in the circumferential direction, and three The three oblique cut surfaces 4 on the short cone 3 are staggered with each other. The present invention is provided with disc-shaped base 5 at the bottom of nut body 1, and base 5, nut body 1 and cover cap 2 are combined into one, and in base 5 and nut body 1, be shaped on the same interior thread. The cap 2 is welded on the top of the nut body 1 and is in a hemispherical shape with a hollow interior, in which anti-rust butter and the like can be placed. ...

Abstract

An antitheft and antirust special nut for railway is composed of bisk-shaped base, nut body and cap, all of which are integrated together. Said nut body with internal spiral threads is composed of at least two short truncated cones overlapped. Each truncated cone has at least 3 oblique tangent surfaces. Its advantages are simple structure, high antitheft capability, safety and fastness, and long service life.

Description

technical field [0001] The invention relates to a nut structure which is specially matched with a rail line and has anti-theft and anti-rust effects, and belongs to a fastener. Background technique [0002] At present, the nuts used to fix the rails on my country's railways are basically of a conventional traditional structure. Its shape is a hexagonal nut body, and its inner hole is provided with internal threads. Form a set of fasteners on a bolt. However, since most of the railways are unattended, the way of fixing the rails with hex nuts is easy to be damaged and stolen, which will undoubtedly pose a serious threat to the safety of the railway; in addition, because the fasteners are exposed, it is easy to Affected by the harsh environment of the sun and rain for a long time, it will produce embroidery and reduce the service life, which will also threaten the safety of the railway. Contents of the invention [0003] The object of the present invention is to provide a k...
