Abstract
The invention relates to a lead connecting part heating monitoring nut which comprises a display body, wherein the display body is externally sleeved with a shell capable of moving up and down along the display body, and the outer part of the upper end of the display body is provided with a flange for preventing the shell from separating; the shell is externally provided with a transparent plastic shell, and a color change temperature display sheet is arranged between the shell and the transparent plastic shell; the upper part of the display body is sequentially provided with a permanent magnet and a heat sensitive ferrite, and a spring is arranged between the permanent magnet and the heat sensitive ferrite; the display body is internally provided with a cavity; and the top of the cavity is provided with a strong magnet. During mounting, the strong magnet is sucked at a connecting point by working personnel, and when the strong magnet needs to be taken down, the strong magnet is pulled down by the working personnel directly by hands, thus the nut is convenient and quick to mount and dismount and has high safety.
Description
Technical field
The present invention relates to the out-of-limit indicator of a kind of lead joint temperature, specifically a kind of lead joint heating monitoring nut.
Background technique
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 objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of lead joint simple in structure, easy to use, safe heating monitoring nut is provided.
For achieving the above object, the present invention adopts following technical proposals:
Heating monitoring nut in a kind of lead joint comprises showing body, and the showing 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 showing 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 showing 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 showing body, the top of cavity is provided with strong magnets.
Permanent magnet attracts heat sensitive ferrite during normal temperature, length of spring compressed, showing body and shell are fastened on one, the showing 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 showing body forms.
The invention has the beneficial effects as follows: 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 a structural representation of the present invention;
1 shell wherein, 2 heat sensitive ferrites, 3 colour changing thermal indicutor sheets, 4 springs, 5 permanent magnets, 6 strong magnets, 7 showing body, 8 transparent plastic shell.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, heating monitoring nut in a kind of lead joint comprises showing body 7, and showing body 7 outsides are with can be along its shell that moves up and down 1, and outside, showing 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.Showing 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 showing 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 invention is realized by strong magnets 6 that mainly the staff only needs be buckled in the joint to the present invention during installation, is adsorbed on the joint by the magnetic force of strong magnets 6 and gets final product.Scribble eye-catching color on the showing body 7, as yellow and red, the staff can observe easily from afar like this, and normal working lower casing 1 wraps showing 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.
