Abstract
A resistance strain gauge protective structure comprises an adhesive tape, an absorbent cotton layer, a medical proof fabric and a sealant layer, wherein two side surfaces of the absorbent cotton layer are respectively bonded with the adhesive tape and the medical proof fabric, the medical proof fabric is covered by the sealant layer, area of the adhesive tape is substantially equal to that of the absorbent cotton layer, and area of the medical proof fabric is slightly larger than that of the absorbent cotton layer. The resistance strain gauge protective structure improves accuracy degree of testing results, and has protection and moistureproof effects on the strain gauge. The resistance strain gauge protective structure is convenient in usage and simple in operation, and can guarantee accuracy and stability of working of the strain gauge.
Description
Technical field
The utility model relates to a kind of resistance strain gage protection structure, is used for resistance strain gage protection and moistureproof.
Background technology
Present stage, resistance strain gage is widely used in the stress-strain test of member.Because of the damage of foil gauge and make moist and to influence the operate as normal of foil gauge, so that the protected working of foil gauge seems is particularly important.Usually, be directly at the foil gauge that pastes and connect lead-in wire top and be coated with one deck protective agent and play protection and moisture-proof role.But, the not only distortion of limiting resistance foil gauge to a certain extent of protective agent in this manner, thus test result is exerted an influence; And, be unfavorable for the protection of foil gauge because protective agent directly contacts with foil gauge.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of resistance strain gage protection structure, has solved under the prerequisite of not limit strain sheet distortion protection and moistureproof problem to foil gauge.
For solving the problems of the technologies described above; the technical scheme that the utility model is taked is: a kind of resistance strain gage protection structure; it is made up of adhesive tape, degreasing cotton layer, medical proof fabric, sealant layer; the degreasing cotton layer two sides are bonding with adhesive tape, medical proof fabric respectively, and the medical proof fabric skin is covered with sealant layer.
Described adhesive tape and degreasing cotton layer area are about equally.
The area of described medical proof fabric is a bit larger tham the area of degreasing cotton layer.
A kind of resistance strain gage of the utility model protection structure, adhesive tape and degreasing cotton layer area being connected to go between and being advisable about equally and can cover resistance strain gage and weldering.The area of medical proof fabric is a bit larger tham the area of degreasing cotton layer, and the medical proof fabric outside is coated with one deck polymer sealant and plays moisture-proof role.The utility model structure has improved the accuracy of test result, simultaneously foil gauge is played better protect and moisture-proof role.Easy to use, simple to operate, the accuracy of assurance resistance strain gage work, stability.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structural drawing;
Be followed successively by from bottom to up: 1, adhesive tape, 2, degreasing cotton layer, 3, medical proof fabric, 4, sealant layer.
Embodiment
A kind of resistance strain gage protection structure, it is made up of adhesive tape 1, degreasing cotton layer 2, medical proof fabric 3, sealant layer 4, and degreasing cotton layer 2 two sides are bonding with adhesive tape 1, medical proof fabric 3 respectively, and medical proof fabric 3 skins are covered with sealant layer 4.Described adhesive tape 1 and degreasing cotton layer 2 areas about equally, the area of described medical proof fabric 3 is a bit larger tham the area of degreasing cotton layer 2.
In the component stress strain detecting, paste resistance strain gage.With the cotton layer 2 of hair dryer stripping fat, remove the moisture in the degreasing cotton layer 2, with primer band 1, degreasing cotton layer 2, medical proof fabric 3 whole stickups on the dielectric base, note covering resistance strain gage and connect lead-in wire.Polymeric seal glue-line 4 is smeared in medical proof fabric 3 outsides, forms " protection quilt ".
