Description
Technical field
The utility model belongs to petroleum thread detection field, particularly relates to a kind of oil tight thread apart from dip stick.
Background technology
Petroleum thread gauge is the degree of depth machinery converted products requiring high, consumption large in petroleum engineering, and the major parameter of general petroleum thread gauge is compact distance value.The method that compact distance measured by current petroleum thread gauge mainly contains two kinds, a kind of method is directly measured the compact distance value of external thread gauge in laboratory environments, the compact distance measurement result that this method obtains is more accurate, but measure and must carry out under the laboratory environment of constant temperature and humidity, most of work on the spot environment cannot meet.Second method uses scene at petroleum thread gauge, depth gage and vernier caliper is indirectly utilized to measure the thick distance of the Distance geometry feeler gauge dish of circular bead surface in the outer circular bead surface to ring gauge of feeler gauge respectively, the compact distance value of external thread gauge is gone out again by formulae discovery, this method is widely used in most of in-site measurement, but its measurement result is got by twice indirect inspection, and the special circumstances that when the common slide calliper rule of use design in measuring, unpromising petroleum thread gauge compact distance is measured are considered, different users is in use in measuring position and the difference applying dynamometry, capital causes the uncertainty of measurement result to increase.Meanwhile, the second measuring method is measured at every turn all to be needed to record multi-group data, by calculating compact distance measurement result, also can increase Measuring Time, affect work efficiency in daily production Survey Operations.
Utility model content
The purpose of this utility model is to provide a kind of oil tight thread apart from dip stick, and being intended to solve existing petroleum thread gauge needs repeatedly step measurement, and measurement result affects larger problem by different users.
The utility model realizes like this, a kind of oil tight thread apart from dip stick comprise be made up of the first measuring surface and the second measuring surface fix slide calliper rule in the fastener of feeler gauge card for clamping, the digital display dial plate providing numerical value to show, be used for directly measuring the 3rd measuring surface of circular bead surface outside circular bead surface to ring gauge in feeler gauge, being arranged on the upside of described digital display dial plate for locking the first locking knob of the 3rd measuring surface, being arranged on rear side of digital display dial plate for locking the second locking knob of the second measuring surface.
Further, the first described measuring surface and described digital display dial plate are set to one.
Further, the second described measuring surface and the 3rd measuring surface are slided in the housing of described digital display dial plate.
Further, described first measuring surface, the second measuring surface, the 3rd measuring surface, the first locking knob, the second locking knob are Bi-metal Steel Aluminum structure.
Further, described digital display dial plate employing scale division value is the capacitor grid transducer parts of 0.001mm.
The utility model can be used for all kinds of petroleum threads such as oil pipe, sleeve pipe, line pipe, the direct measurement of compact distance numerical value can be realized, there is compact, simple, easy to operate, the digital feature that is stable, that directly measure of structure, both can be used for using when petroleum thread working gauge detects workpiece screw thread, use when also can be used for oil check and correction external thread gauge calibration petroleum thread working gauge, overcome in prior art and need repeatedly step measurement, measurement result affects larger shortcoming by different users.
