Abstract
The utility model relates to strain resistor spring pad, its structure is, the outer surface of spring pad scribbles isolation layer, the outer surface of isolation layer is installed ga(u)ge line construction layer, the two ends of ga(u)ge line construction layer have leading out terminal, resistance wire in ga(u)ge line construction layer is obliquely installed, and angle of inclination is 15 degree.The utility model is suitable for all need to use the fixing industry of bolt assembly, volume is little, easy for installation, can react the plurality of advantages that bolt combination part and pressure rotating shaft rotating component degree of tightness are measured, had basic spring pad, and the hidden danger of remover apparatus operation in time, guarantee equipment security of operation.
Description
Technical field
The utility model relates to a kind of spring pad, relates in particular to a kind of strain resistor spring pad that straingauge is installed, and is widely used in the fastening installation of bolt assembly.
Background technique
Spring pad has resilience can effectively prevent nut loosening, and therefore, spring pad is widely used in the combination of screw, nut and fastening installation.But spring pad of the prior art only limits to fastening installation, function ratio is more single.
Model utility content
The utility model, for above-mentioned problems of the prior art, provides a kind of strain resistor spring pad, has solved the more single problem of existing prior art medi-spring cushion function.
The technical solution of the utility model is as follows:
The outer surface of spring pad scribbles isolation layer, and the outer surface of isolation layer is installed ga(u)ge line construction layer, and the two ends of ga(u)ge line construction layer have leading out terminal, and the resistance wire in ga(u)ge line construction layer is obliquely installed, and angle of inclination is 15 degree.
Described spring pad is Rectangular Spring pad.
Described isolation layer comprises insulation prime coat and insulating surfaces enamelled coating.
Resistance wire in described ga(u)ge line construction layer becomes " bow " font to be equidistantly obliquely installed.
The advantageous effect of the utility model patent is as follows:
1, strain resistor spring pad volume is little, easy for installation, can react the plurality of advantages that bolt combination part and pressure rotating shaft rotating component degree of tightness are measured, had basic spring pad.The hidden danger of remover apparatus operation in time, guarantees equipment security of operation.
2, the resistance value of ga(u)ge line construction layer, the pressure suffered according to spring pad produces planar distortion power, thereby changes electrostrictive strain resistance layer resistance value.Leading out terminal can be connected fastening nuts Cheng Du is entered to record with electronic metering equipment.
3, empirical tests, resistance wire becomes 15 degree to be obliquely installed, and produces planar distortion power the sensitiveest, and resilience effect is best, and long service life, should not damage.
4, isolation layer adopts insulation prime coat and insulating surfaces enamelled coating, has played insulating effect, does not affect again stretch capability and the resilience of spring itself.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure, 1, spring pad, 2, ga(u)ge line construction layer, 3, leading out terminal.
Embodiment
The utility model, with reference to accompanying drawing, in conjunction with specific embodiments, is described in detail as follows.
Embodiment
As shown in Figure 1, the outer surface of Rectangular Spring pad 1 scribbles isolation layer, and isolation layer comprises PUA moisturecuring
The senior corrosion resistant coating Q/YJT of polyurethane 010-2005 insulation prime coat and the senior corrosion resistant coating Q/YJT of PUA moisture cure urethanes 010-2005 insulating surfaces enamelled coating, the outer surface of isolation layer is installed ga(u)ge line construction layer 2, the two ends of ga(u)ge line construction layer have leading out terminal 3, resistance wire in ga(u)ge line construction layer becomes " bow " font to be equidistantly obliquely installed, and angle of inclination is 15 degree.
When use, strain resistor spring pad is installed in bolt assembly, after bolt and structural member clamp strain resistor spring pad, the meeting generation curved surface tension force of the ga(u)ge line construction layer on strain resistor spring pad, the twill ga(u)ge line value of having a resistance that stretches inner changes, after bolt assembly occurs to become flexible, strain resistor spring pad has resilience can make its ga(u)ge line reply original resistance value.By recording the variation of resistance value, whether looseningly reach understanding bolt assembly.
Claims (4)
1. strain resistor spring pad, the outer surface that it is characterized in that spring pad scribbles isolation layer, and the outer surface of isolation layer is installed ga(u)ge line construction layer, and the two ends of ga(u)ge line construction layer have leading out terminal, resistance wire in ga(u)ge line construction layer is obliquely installed, and angle of inclination is 15 degree.
