Abstract
A bolt connection loosening indicator relates to a device for indicating loosening between a nut and a connector by using the principle of light reflection. On one hand, the bolt connection loosening indicator has the function of light reflection, on the other hand, one end, without a light reflection indicator with the function of light reflection, of a sheet is fixedly connected with a steel wire which is used for being inserted between the nut and the connector for fixing purpose, the other end of the light reflection indicator sheet is provided with a suspension hole, and a hook of a spring is suspended to the suspension hole of the light reflection indicator sheet. Working staff can timely find out loosening of the nut mounted at a higher place and carry out treatment according to the condition of light reflection. The bolt connection loosening indicator has the advantages of simple structure and simple installation.
Description
Technical field
The utility model relates to the utensil that the loosening phenomenon of bolt component connection back generation is indicated, and particularly utilizes light reflection principle that nut and coupling are produced the apparatus that loosening phenomenon is indicated.
Background technique
Bolt Connection is comparatively extensive, and particularly electric power pylon, bridge, urban facilities etc. owing to the influence of natural causess such as wind, are easy to cause nut loosening, and simultaneously, the nut of eminence occurs loosening, is difficult to find.The nut of some is loosening, changes the conduction orientation of power, if processing is untimely, and the generation that very easily causes the accident, even form catastrophic consequence.
The model utility content
The purpose of this utility model provides the loosening indicator of a kind of Bolt Connection, is intended to indicate and find the loosening of nut by light reflection principle, so that in time handle.
This novel purpose is achieved in that a kind of Bolt Connection becomes flexible indicator, reflective indicating piece simultaneously has the reflection ray function, another side does not have reflection ray function (or the reflection ray function is not strong), reflective indicating piece one end is fixedly connected with one as inserting the steel wire of fixing between nut and the coupling, the reflective indicating piece the other end has a hanging hole, and the hook of spring is articulated on the hanging hole of reflective indicating piece.
Above-mentioned reflective indicating piece is circular, and the line of hanging hole center and the steel wire immovable point on reflective indicating piece passes the center of circle of circular reflective indicating piece.
The diameter of bore of above-mentioned spring is slightly larger than the outer diameter of coupling screw rod.
This novel beneficial effect is:
1, can in time find to be installed in the loosening problem of eminence nut by light reflection principle
Before nut screws, with the steel wire on the reflective indicating piece, insert in right amount between nut and the connecting piece, and the reflecting surface of reflective indicating piece is affixed on or, subsequently, firmly screws nut towards being coupled part.After nut screws, spring is not had hook one end, screw in screw rod along the screw flight direction, last, flexural spring makes hook that reflective indicating piece is hung the jail.
After the installation, when nut loosens to a certain degree, can't be with fixing wire clip at nut and be coupled between the part, the elasticity of spring changes the position between reflective indicating piece and the nut or breaks away from, even swings in wind.The staff can in time find the loosening of nut according to the situation of loosening indicating piece reflection ray, and it is handled timely.
2, this new design novelty, simple in structure, user cost is low.
Description of drawings
Fig. 1 is this novel schematic perspective view.
Embodiment
This is novel is made up of fixedly steel wire, reflective indicating piece and spring, and through preservative treatment.
Fixing steel wire: made by fine wire or the stronger silk thread of toughness, an end is connected with reflective indicating piece, and the other end is clipped between nut and the connecting piece;
Reflective indicating piece 1: be metal or other material thin slices, one side has a reflection ray function, another side do not have or the function of reflection ray not strong, reflective indicating piece somewhere is provided with a hanging hole 1a, is convenient to hang on the spring.Farthest in the hole, reflective indicating piece is connected with fixing steel wire;
Spring 3: for having the common spring of certain-length, internal diameter is suitable mutually with the screw rod external diameter of application.Spring one end is provided with hook 3a, can pass through the hole on the reflective indicating piece, and reflective indicating piece is hung the jail, and the other end connects mutually with the screw rod of application.
The description of product: the finished product before using is made up of two-part, that is, steel wire is arranged fixedly and be provided with the reflective indicating piece in hole at another place and the spring that an end is provided with hook.
Application process: before nut screws,, insert in right amount between nut and the connecting piece, and the reflecting surface of reflective indicating piece is affixed on or, subsequently, firmly screws nut towards being coupled part with the steel wire on the reflective indicating piece 2.After nut screws, spring is not had hook one end, screw in screw rod along the screw flight direction, last, flexural spring makes hook that reflective indicating piece is hung the jail.
The indication principle: after the installation, when nut loosens to a certain degree, can't be with fixing wire clip at nut and be coupled between the part, the elasticity of spring changes the position between reflective indicating piece and the nut or breaks away from, even swings in wind.The staff can in time find the loosening of nut according to the situation of loosening indicating piece reflection ray.
Application area: personnel are difficult for facility that the eminence of touching or observing adopts bolted on connection, framework etc.
