Abstract
The utility model relates to a heating monitoring nut for the connecting position of wires, comprising a displaying body; the displaying body is externally sheathed with a shell capable of moving from top to bottom along with the displaying body; the upper end of the displaying body is externally provided with a flange for preventing the shell from separating; the shell is externally provided with a transparent plastic shell, a color-changing temperature displaying piece is arranged between the shell and the transparent plastic shell, the upper part of the displaying body is provided with a permanent magnet and a heat-sensitive ferrite in sequence, and a spring is arranged between the heat-sensitive ferrite and the permanent magnet; and the displaying body is internally provided with a cavity, and the top of the cavity is provided with a strong magnet. In installation, the heating monitoring nut is absorbed at the joint with the strong 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.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of lead junction simple in structure, easy to use, safe heating monitoring nut being provided.
For achieving the above object, the utility model adopts following technical proposals:
Heating monitoring nut in a kind of lead junction comprises display body, and the display body outside is with can be along its shell that moves up and down, and the outside flange that prevents that shell breaks away from that is equipped with in display body upper end; The outside of shell is provided with transparent plastic shell, is provided with the colour changing thermal indicutor sheet between shell and the transparent plastic shell, and display body top is provided with and is provided with permanent magnet and heat sensitive ferrite successively, and is provided with spring between heat sensitive ferrite and the permanent magnet; Be provided with cavity in the display body, the top of cavity is provided with strong magnets.
Permanent magnet attracts heat sensitive ferrite during normal temperature, length of spring compressed, display body and shell are fastened on one, the display body body comprise with shell in, transparent plastic shell is wrapped in shell, transparent plastic shell and shell have formed a cavity, and the colour changing thermal indicutor sheet is arranged in the cavity, and strong magnets is fixed on the cavity top that display body forms.
The beneficial effects of the utility model are: by the staff monitoring nut is pull-in on the node place with strong magnets 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 the utility model structural representation;
1 shell wherein, 2 heat sensitive ferrites, 3 colour changing thermal indicutor sheets, 4 springs, 5 permanent magnets, 6 strong magnets, 7 display body, 8 transparent plastic shell.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, heating monitoring nut in a kind of lead junction comprises display body 7, and display body 7 outsides are with can be along its shell that moves up and down 1, and outside, display body 7 upper end is equipped with the flange that prevents that shell breaks away from; The outside of shell 1 is provided with transparent plastic shell 8, is provided with colour changing thermal indicutor sheet 3 between shell 1 and the transparent plastic shell 8, and transparent plastic shell 8 is wrapped in shell 1 and transparent plastic shell 8 integral body are transparent, and the staff can see the colour changing thermal indicutor sheet 3 of the inside from afar.Display body 7 tops are provided with and are provided with permanent magnet 5 and heat sensitive ferrite 2 successively, and are provided with spring 4 between heat sensitive ferrite 2 and the permanent magnet 5; Be provided with cavity in the display body 7, the top of cavity is provided with strong magnets 6.
Heat sensitive ferrite 2 is very responsive with variation of temperature, and under normal temperature, heat sensitive ferrite 2 and permanent magnet 5 are pulled together, and when temperature was too high, the magnetic conductance of temperature-sensitive iron oxygen iron 2 descended, and breaks away from permanent magnet 5, and spring 4 is upspring shell 1 and reported to the police.
Installation of the present utility model is realized by strong magnets 6 that mainly the staff only needs be buckled in the joint to the utility model during installation, is adsorbed on the junction by the magnetic force of strong magnets 6 and gets final product.Scribble eye-catching color on the display body 7, as yellow and red, the staff can observe easily from afar like this, and normal operating conditions lower casing 1 wraps display body 7, and colour changing thermal indicutor sheet 3 is placed in shell 1 and the transparent plastic shell 8 formed cavitys.
Heat sensitive ferrite has a lot of different temperature sensitivity models in addition, the user can select suitable product according to own demand oneself to working environment 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.
