Utility model content
The deficiency that the utility model exists for prior art just, a kind of hoop tensile strength test separator disk is provided, can guarantee that sample and dilating effect power are on same axis, the internal diameter of proving installation and conduit is fitted completely, avoid producing load, institute's load application is stable, evenly, can the not exert an influence slip of test result of glass fiber reinforced plastics cable duct tube.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of hoop tensile strength test separator disk, comprise: set casing, linking arm, semi-disc, described set casing comprises end face, bottom surface and left side wall, described set casing left side wall is fixedly connected with described linking arm, the right side of described set casing is without sidewall, described semi-disc be fixedly arranged between the end face of described set casing and bottom surface and the straight flange of described semi-disc towards the right side of described set casing.
As the improvement of technique scheme, also comprise bolt, the end face of described set casing and bottom surface are provided with through hole one, and described semi-disc is provided with through hole two, and described bolt is through described through hole one and described through hole two.
As the improvement of technique scheme, described linking arm sidewall is provided with anti-skidding knurling.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Hoop tensile strength test separator disk described in the utility model, can guarantee that sample and dilating effect power are on same axis, the internal diameter of proving installation and conduit is fitted completely, avoid producing load, institute's load application is stable, evenly, can the not exert an influence slip of test result of glass fiber reinforced plastics cable duct tube; In addition, there is intensity high, the distortion of the test that do not exert an influence within the scope of a constant load; Temperature, humidity requirement are low, can meet the advantage of all kinds of experimental enviroments.Through practice, confirm there is the ability of carrying out reliable test under multiple testing machine condition.
