Abstract
The utility model provides an o-shaped sealing ring measuring scale comprising a measuring scale body, a middle part of which is provided with scales. An upper edge and a lower edge of the measuring scale body are provided with circular gaps. The diameters of the circular-shaped gaps are corresponding to the diameter of the cross section of the O-shaped sealing ring. The utility model is advantageous in that by using the O-shaped sealing ring as the standard component, the common measuring scale can be reconstructed, and the specifications of the diameters of the cross sections of the common O-shaped sealing rings can be quantified on the scale by adopting the circular-shaped gaps according to the related national standard, and therefore the measurement of the O-shaped sealing ring can be quick and accurate, the structure is simple, the costs are low, the use is convenient, and at the same time, the sealing ring can be provided with the functions of the common measuring scales.
Description
Technical field
The utility model relates to a kind of survey instrument, specifically refers to a kind of O RunddichtringO Special measuring scale.
Background technology
The O RunddichtringO gage providing is in the market the flexible chi that a kind of flexible material is made, and structure consists of main scale and secondary chi, and this flexible chi is used comparatively complicated, reading trouble.
Except the flexible chi of this O RunddichtringO, also having a kind of is exactly the O RunddichtringO survey instrument that is referred to as to measure cone, is measuring on cone at present, and each section is corresponding with certain a series of specification, thereby is convenient to by the internal diameter matching measurement of O RunddichtringO out.
Except these two kinds of O RunddichtringO survey instruments, more there is not again the special measurement instrument of measuring for O RunddichtringO.In the daily servicing of plant equipment, in order to use and to take conveniently, usually the O RunddichtringO of all size to be put together, during use, select as required again, use this two kinds of survey instrument time and effort consumings, can not rapidly the O RunddichtringO of different size be picked out.
Utility model content
The utility model provides the dip stick that a kind of energy is simple and easy, measure quickly and accurately O RunddichtringO diameter of section.
For achieving the above object, the utility model is by the following technical solutions:
An O RunddichtringO dip stick, comprises dip stick body, and described dip stick body centre position is provided with scale, and the upper and lower both sides of described dip stick body are provided with circumferential notch, and this circumferential notch diameter is corresponding with O RunddichtringO diameter of section.
Described circumferential notch is 3/4 circle.
The beneficial effects of the utility model are:
Utilize the feature that O RunddichtringO is standard component, common dip stick is transformed, according to the countries concerned's standard, by the specification of conventional O RunddichtringO with the form quantification of circumferential notch on ruler, improve the measuring speed to conventional O RunddichtringO specification, significantly improved work efficiency; Circumferential notch is 3/4 circle, and it is more accurate to make to measure; Simple in structure, with low cost, easy to use, the while also has the function of general measure chi.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of O RunddichtringO dip stick, comprises dip stick body, in the middle of dip stick body, is provided with scale, and the upper and lower both sides of described dip stick body are provided with circumferential notch, and this circumferential notch diameter is corresponding with O RunddichtringO diameter of section specification.Upper and lower limit, the dip stick body left side is conventional O RunddichtringO diameter of section specification in GB3452.1-92 and GB12325-76; Upper and lower limit, the right is conventional O RunddichtringO diameter of section specification in DIN standard
According to GB3452.1-92, O RunddichtringO specification is described with internal diameter * diameter of section; Stipulated that internal diameter is from 1.8～670mm, O RunddichtringO is 1.80 ± 0.08,2.65 ± 0.09,3.55 ± 0.10,5.30 ± 0.13,7.00 ± 0.15 to amount to 5 specifications.
According to GB12325-76 standard O RunddichtringO dimension mark method: external diameter x diameter of section, O RunddichtringO specification is from 5x1.9～500x8.6, and O type ring cross-section diameter is 1.9,2.4,3.1,3.5,5.7,8.6 to amount to 6 specifications.
Because current domestic import equipment is more, therefore for the O RunddichtringO dimension mark method requiring in DIN standard: external diameter x diameter of section, O RunddichtringO specification is from 5x1.9～500x8.6, and O type ring cross-section diameter is 1.5,2.4,2.6,2.62,3.0,3.55,5.33,5.0,6.0,7.0,8.6 to amount to 11 specifications.
The utility model has represented the specification of 20 conventional O RunddichtringOs in GB3452.1-92, GB12325-76, DIN standard with the circumferential notch of 3/4 circle, can determine with pattern form the diameter of section of O RunddichtringO; Its measurement range is that diameter of section is between 1.5-8.6mm, between internal-and external diameter 0-300mm; Therefore for all available dip stick realizations of measurement of commonly using O RunddichtringO.
While using this dip stick, as long as the breach on O type circle and the upper and lower both sides of dip stick is compared, just can measure the diameter of section of O RunddichtringO, measurement for internal diameter or external diameter, O RunddichtringO is kept flat in one plane, with the scale in the middle of dip stick, just can measure internal-and external diameter.
Claims (2)
1. an O RunddichtringO dip stick, comprises dip stick body, and described dip stick body centre position is provided with scale, it is characterized in that: the upper and lower both sides of described dip stick body are provided with circumferential notch, and this circumferential notch diameter is corresponding with O RunddichtringO diameter of section.
2. a kind of O RunddichtringO dip stick as claimed in claim 1, is characterized in that: described circumferential notch is 3/4 circle.
