Abstract
The utility model relates to a kind of slide calliper rule for detection of polyfoam apparent density, and described slide calliper rule comprise four steel rulers, and four steel rulers enclose " well " type, is flexibly connected and can relatively moves between two crossing steel rulers.The utlity model has easy to usely, improve surveying work efficiency, avoid the advantage of the duplication of labour.
Description
Technical field
It is the slide calliper rule of extruded sheet apparent density for detection of polyfoam that the utility model relates to a kind of.
Background technology
In the time carrying out the test of extruded sheet apparent density, need to measure the length of sample preparation, and judge whether prepared sample meets code requirement.Major part is directly measured with vernier caliper at present, but in practical operation, because sample preparation must be the complete rectangular parallelepiped of rule, vernier caliper often blocks askewly in the time measuring like this, to such an extent as to the data error of reading is larger, cause the sample of preparation undesirable, need sample preparation again, both lost time like this, energy, waste detects resource again, also fall flat, when serious, even defective sample is mistaken for to qualified sample.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, provides a kind of easy to use, improves surveying work efficiency, avoids the slide calliper rule for detection of polyfoam apparent density of the duplication of labour.
The purpose of this utility model is achieved through the following technical solutions: a kind of slide calliper rule for detection of polyfoam apparent density, described slide calliper rule comprise four steel rulers, four steel rulers enclose " well " type, be flexibly connected and can relatively move between two crossing steel rulers.
Further improvement of the utility model is: between two steel rulers that intersect, be bolted.
Further improvement of the utility model is: on each steel ruler, be equipped with the shifting chute moving for described bolt.
The utility model compared with prior art has the following advantages: use more for convenience, and can ensure the high precision of measuring, improved the work efficiency of measuring, avoided the duplication of labour, make measurement result more accurate.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-steel ruler, 2-bolt, 3-shifting chute.
embodiment:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows the embodiment of a kind of slide calliper rule for detection of polyfoam apparent density of the utility model, described slide calliper rule comprise four steel rulers 1, four steel rulers 1 enclose " well " type, between two steel rulers 1 that intersect, be flexibly connected and can relatively move, fixing by bolt 2 between two steel rulers 1 that the utility model preferably intersects, on each steel ruler 1, be equipped with the shifting chute 3 moving for bolt 2.
Slide calliper rule for detection of polyfoam apparent density described in the utility model, connect into quadrilateral by four steel rulers, in the time measuring sample, block sample both sides with disjunct two steel rulers 1 staggered relatively, then any one of mobile other both sides ruler reading, and so not only use more for convenience, and can ensure the high precision of measuring, improve the work efficiency of measuring, avoided the duplication of labour, made measurement result more accurate.
