Abstract
The invention relates to a heating monitoring screw cap at a lead joint. The heating monitoring screw cap is convenient and fast to assemble and disassemble and has high safety. The heating monitoring screw cap comprises a shell, a bimetallic strip, a spring, a transparent plastic shell, a color change heat indicating plate, a display body and a permanent magnet, wherein an annular groove is formed in the cavity of the shell; the top of the bimetallic strip is provided with a hook; the hook at the top of the bimetallic strip hooks the groove at a normal temperature; the lower end of the bimetallic strip is fixedly connected with the display body at the lower part of the screw cap; the spring is arranged between the shell and the display body; and the permanent magnet is arranged in a concave hole of the display body.
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 to address the above problem, heating monitoring nut in a kind of lead joint is provided, the out-of-limit indicator of this temperature directly is fastened on connection part when mounted.
The technological scheme that technical solution problem of the present invention is taked is:
A kind of lead joint heating monitoring nut, comprise shell, bimetallic strip, spring, transparent plastic shell, colour changing thermal indicutor sheet, showing body and permanent magnet, the cavity inside of described shell is provided with the groove of an annular, the top of bimetallic strip is a hook, the top hook of bimetallic strip hooks described groove during normal temperature, the showing body of the lower end of described bimetallic strip and nut bottom is consolidated, and spring is installed between shell and the showing body, and permanent magnet is installed in the shrinkage pool of showing body.
Described bimetallic strip has two.
The invention has the beneficial effects as follows: 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 invention.
Among the figure: 1 shell, 2 bimetallic strips, 3 springs, 4 transparent plastic shell, 5 colour changing thermal indicutor sheets, 6 showing body, 7 permanent magnets.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, bimetallic strip 2 is key components wherein in the nut, bimetallic strip 2 is mainly lumped together by two kinds of different metal-to-metal adhesives of temperature sensitivity to be formed, two metal temperature distortions during temperature variation, and because the receptance difference of temperature, the degree differences of two metal bendings distortion, this just makes bimetallic strip bend towards place away from groove.In this nut, the hook at bimetallic strip 2 tops hooks the groove of the annular on the part of shell in cavity during normal temperature, this is that spring 3 is in compressive state, but because bimetallic strip 2 is hooked in the groove, makes spring 3 can only be in compressive state, bimetallic strip 2 distortion when temperature raises, bimetallic strip 2 bends towards the place away from groove, and bimetallic strip 2 hooks the groove position to be opened, spring 3 diastoles, outside the showing body 6 outstanding shells, and then play warning effect.Transparent plastic shell 4 is wrapped in shell 1, transparent plastic shell 4 has formed a cavity with shell 1, colour changing thermal indicutor sheet 5 is arranged in the cavity, permanent magnet 7 is fixed on the cavity top that showing body 6 forms, the installation of this nut mainly goes to finish by permanent magnet 7, and the staff is placed on the joint to nut and is adsorbed on the joint by the magnetic force of permanent magnet 7 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 fuds fuddled 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.
Claims (2)
1. nut is monitored in a lead joint heating, comprise shell, bimetallic strip, spring, transparent plastic shell, colour changing thermal indicutor sheet, showing body and permanent magnet, it is characterized in that, the cavity inside of described shell is provided with the groove of an annular, the top of bimetallic strip is a hook, the top hook of bimetallic strip hooks described groove during normal temperature, the showing body of the lower end of described bimetallic strip and nut bottom is consolidated, spring is installed between shell and the showing body, and permanent magnet is installed in the shrinkage pool of showing body.
2. heating monitoring nut in lead as claimed in claim 1 joint is characterized in that described bimetallic strip has two.
