Abstract
The utility model discloses a heating monitoring nut for connecting positions of wires, comprising heat deformation metal. The heat deformation metal is positioned in a cavity formed by a shell and a displaying body; the bottom of the heat deformation metal is adhered with the displaying body; the shell is wrapped by a transparent plastic shell; the cavity formed by the shell and the transparent plastic shell is internally provided with a color-changing temperature displaying piece; and a permanent magnet is fixedly arranged at the upper part of the cavity of the displaying body. In installation, the heating monitoring nut is absorbed at the joint with the permanent magnet by a worker, is directly pulled by hands of the worker when needing to be taken down, and is very convenient and fast to install and disassemble and high in safety.
Description
Technical field
The utility model relates to the out-of-limit indicator of a kind of lead junction temperature, specifically a kind of lead junction heating monitoring nut.
Background technology
At present, in power industry, have the many kinds of out-of-limit indicators of temperature, but the out-of-limit indicator of these temperature all exists very big potential safety hazard, now the major part of using on the market all is the nut form of tightening, the time that hand contacted with nut when the out-of-limit indicator of this form ground temperature was installed is oversize, just exists very big danger for high-tension line like this.
The utility model content
The purpose of this utility model is to provide a kind of lead junction heating monitoring nut, and this monitoring nut directly is fastened on connecting portion when mounted.
A kind of lead junction heating monitoring nut, it comprises shell, and shell pivot bush unit display body is provided with groove at the display body top, is provided with the thermal deformation metal in the groove, and bottom portion of groove is provided with the permanent magnet that matches with shell; Described thermal deformation metal bottom and display body are glued together; Shell edge is wrapped up by transparent plastic shell, is provided with the colour changing thermal indicutor sheet in the cavity that both form.
The beneficial effects of the utility model are: the thermal deformation metal is the head-bent state when normal temperature in the utility model, the sweep of thermal deformation metal becomes straight when temperature is high, the thermal deformation metal that is out of shape in the nut is shell jack-up, and this moment, the variable color of colour changing thermal indicutor sheet was reported to the police to temperature.By the staff monitoring nut is pull-in on the node place with permanent magnet during installation, the staff directly gets final product with pulling down when taking off, and installing/dismounting is all easily quick, and safe.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 shell, 2 thermal deformation metals, 3 transparent plastic shell, 4 display body, 5 permanent magnets.
Embodiment
As shown in Figure 1, a kind of lead junction heating monitoring nut, it comprises shell 1, thermal deformation metal 2, transparent plastic shell 3, display body 4, permanent magnet 5, described thermal deformation metal 2 is major parts of whole nut, thermal deformation metal 2 head-bents are in the cavity of nut during normal temperature, and the display body 4 of thermal deformation metal 2 bottoms and lower end is glued at one, if the thermal deformation master metal is with the profile variation different shape of variation of temperature metal, here our the thermal deformation metal 2 used is the head-bent state when normal temperature, and the sweep of thermal deformation metal 2 becomes straight when temperature is high.Transparent plastic shell is wrapped in shell, and transparent plastic shell and shell have formed a cavity, and the colour changing thermal indicutor sheet is arranged in the cavity, and when the thermal deformation metal that is out of shape in the nut during shell jack-up, the variable color of colour changing thermal indicutor sheet is reported to the police to temperature.Permanent magnet is fixed on the cavity top that display body forms, and the installation of this nut mainly goes to finish by permanent magnet, and the staff is placed on the joint to nut and is adsorbed on the junction by permanent magnet magnetic force and gets final product during installation.
Heat sensitive ferrite has a lot of different temperature sensitivity models in addition, the user can be according to the own pattern that the demand oneself of working environment is customized nut like this, this product mainly is applicable to the transportion wire of power industry, also is applicable to the temperature monitoring of other industry commute heater.
