Abstract
The invention relates to a heated monitoring bolt at a lead connecting position, which comprises a shell, wherein an upper cavity and a lower cavity are arranged in the shell; an indicating rod is arranged in the upper cavity; the upper part of the indicating rod is fixed by double metal sheets which are arranged in the upper cavity; one end of the indicating rod corresponds to a side opening of the shell, and the other end is connected with a spring fixed on the inner wall of the shell; and a clamping switch penetrates through the lower cavity of the shell. When in installation, a staff directly inserts the heated monitoring bolt in a node; and after the heated monitoring bolt is inserted, the clamping switch can firmly clamp a temperature out-of-limit indicator in the node. The heated monitoring bolt can be taken out after the clamping switch is released, and the invention has the advantages of convenient and rapid assembly and disassembly and high safety.
Description
Technical field
The present invention relates to the out-of-limit indicator of a kind of line junction temperature, especially a kind of lead junction heating monitoring bolt.
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 be the nut form of tightening, but the nut form the out-of-limit indicator of temperature exist when mounted and set about the overlong time that contacts with nut and dangerous problem.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple structure, lead junction heating easy to use, safe to monitor bolt.
For achieving the above object, the present invention adopts following technical proposals:
A kind of lead junction heating monitoring bolt, comprise housing, be provided with two cavitys up and down in the housing, be provided with indicator stem in the upper cavity, indicator stem top is fixed by the bimetallic strip that is arranged in the upper cavity, indicator stem one end is corresponding with the side opening of housing, and the other end links to each other with spring on being fixed on inner walls; Be provided with the screens switch that penetrates wherein in the housing lower chamber.
Described housing top is provided with upper cover.
Described screens switch comprise level insert in the lower chamber about two buttons, and oblique cutting goes into two cards in the lower chamber, connects by the rigidity paster that is positioned at lower chamber between described corresponding buttons and the card.
The invention has the beneficial effects as follows: directly be inserted in the node place by the staff during installation, insert back screens switch and can be stuck in the node place to the out-of-limit indicator of temperature firmly.Can unclamp the screens switch when taking off earlier and take out, installing/dismounting is all easily quick, and safe.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1;
1 upper cover wherein, 2 housings, 3 indicator stems, 4 springs, 5 screens switches, 6 bimetallic strips.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of lead junction heating monitoring bolt, comprise housing 2, be provided with two cavitys up and down in the housing 2, be provided with indicator stem 3 in the upper cavity, indicator stem 3 tops are fixing by the bimetallic strip 6 that is arranged in the upper cavity, and indicator stem 3 one ends are corresponding with the side opening of housing 2, and the other end links to each other with spring 4 on being fixed on housing 2 inwalls; Be provided with the screens switch 5 that penetrates wherein in housing 2 lower chambers.
Described housing 2 tops are provided with upper cover 1.
Described screens switch 5 comprise level insert in the lower chamber about two buttons, and oblique cutting goes into two cards in the lower chamber, this card plays the effect of blocking on body of bolt.Connect by the rigidity paster that is positioned at lower chamber between described corresponding buttons and the card, can well unclamp and closure.
Directly the present invention is inserted in the node place by the staff during installation, inserts back screens switch 5 and can be stuck in the node place to the out-of-limit indicator of temperature firmly.Can unclamp screens switch 5 when taking off earlier and take out, installing/dismounting is all easily quick, and safe.
This in addition bolt can be according to demand oneself customization of user oneself to working environment, and this product mainly is applicable to the transportion wire of power industry, also is applicable to the temperature detection of other industry team with heater.
