Abstract
The utility model discloses a three point caliper gauge, a foldable three point caliper gauge, it includes the blade, installs the vernier scale on the blade, has first dipperstick through hinged joint in the one end of blade, has the second dipperstick through hinged joint on the vernier scale to be equipped with the stopper at the position of the first dipperstick of hinged joint and second dipperstick, the contained angle between two stoppers and the blade is the same. The utility model realizes the diameter measurement by the principle that three points are close to the cylindrical object to be measured. That is, the ruler body and the first measuring ruler installed on the ruler body are abutted against the measured cylindrical object, the vernier scale on the ruler body is moved, the ruler body of the second measuring ruler is also contacted with the measured object, and the diameter value of the circular object can be directly read on the ruler body. Simultaneously the utility model discloses an all adopt the activity hinged joint between blade, first dipperstick and the second dipperstick, can conveniently fold up for short and small portable chi, it is very practical.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly a kind of collapsible 3 calibre gauges that are used to measure the cylindricality diameter.
Background technology
At present, the survey instrument that is used for measuring the cylindrical object diameter mostly is vernier caliper.When using vernier caliper measurement, be that the blade length of slide calliper rule must be greater than the diameter of measured circle cylindrical objects to the requirement of vernier caliper; Owing to be subjected to the restriction of above-mentioned condition, when the testee diameter is big, the slide calliper rule that are used for measuring then can be not only greatly but also heavy, be not easy to carry and use.Simultaneously in oilfield drilling, to detect the size of cutting edge on drill bit or the centralizer often, because of the cutting edge on drill bit or the centralizer or roller all are to be 120 degree to be distributed on the right cylinder, the employing vernier caliper measurement is not that the projection that is distributed on the same straight line is very difficult, is difficult to measure accurately yet.
The utility model content
The purpose of this utility model is: provide a kind of collapsible, can directly read a kind of collapsible 3 calibre gauges of cylindrical size, to overcome the deficiencies in the prior art.
The technical solution of the utility model; A kind of collapsible 3 calibre gauges, it comprises blade 1, vernier scale 2 is installed on blade 1, at an end of blade 1 first dip stick 3 that has been connected through the hinge, second dip stick 4 has been connected through the hinge on vernier scale 2, and be provided with limited block 5, two limited blocks 5 at the position that hinge connects first dip stick 3 and second dip stick 4 identical with angle between the blade 1.
Blade 1 is to be connected through the hinge by the short chi 6 more than two sections or two sections to form.
The position that connects at the short chi 6 of per two joints all is provided with contiguous block 7, and contiguous block 7 is fixedlyed connected with the short chi 6 of two a joints joint wherein, is connected through the hinge with another root.
Angle between two limited blocks 5 and the blade 1 is 60 degree.
Compared with the prior art, the utility model is the mensuration that realizes diameter near the principle to cylindrical determinand by 3.Promptly abut against on the measured circle pillars with the blade and first dip stick that is installed on the blade, attachable mechanical stage vernier scale on one's body also contacts the blade of second dip stick with measured object, then can directly read the roundel diameter value on blade.Second dip stick and the equal isogonism of second dip stick are connected on the blade, can be convenient for measuring like this on the right cylinder by three, six, nine equidistributed convexes.All adopt hinges to connect simultaneously between blade of the present utility model, first dip stick and second dip stick, can make things convenient for folding is short and small portable chi; On first dip stick, also be provided with scale, can be convenient for measuring the degree of depth of parts like this, very practical; Therefore the utlity model has excellent popularization is worth.
Figure of description
Fig. 1 is the structural representation that the utility model is in user mode.
Embodiment
Embodiment of the present utility model: as shown in Figure 1, the utility model is to realize measuring diameter by 3 near the principle to cylindrical determinand.Its formation comprises blade 1, the vernier scale 2 that can slide on blade 1 is being installed on the blade 1, the length of blade 1 will be surveyed columniform big or small tailored range according to need, blade 1 can be divided into two joints or the short chi 6 more than two joints after the length of having formulated blade 1, divide the short chi 6 after cutting to be connected through the hinge, its concrete connected mode is: the position that connects at the short chi 6 of per two joints all is provided with a contiguous block 7, contiguous block 7 is fixedly connected on wherein joints that need in the short chis 6 of interconnective two joints, and connecting the back, that hinge is installed on contiguous block 7 is hinged with another joint weak point chi 6.Simultaneously at an end of blade 1 first dip stick 3 that is connected through the hinge, second dip stick 4 is connected through the hinge on vernier scale 2, and limited block 5 is installed at the position at be connected through the hinge first dip stick 3 and second dip stick 4 respectively, two limited blocks of installing 5 can limit the anglec of rotation of first dip stick 3 and second dip stick 4, by limited block 5 first dip stick 3 after opening and second dip stick 4 are equated with angle between the blade 1.For making things convenient for reading to calculate, the angle between limited block 5 and the blade 1 is preferably 60 degree.
In use, open folding the utility model, with blade 1 be installed in first dip stick 3 on the blade and abut against earlier on tested cylindrical 8, attachable mechanical stage vernier scale 2 on one's body again, the blade that makes second dip stick 4 also contacts with tested cylindrical 8, so then cylindrical 8 the diameter value (reading on the blade is surveyed through 3 and scribed after circle calculates) that can directly read on the blade; After finishing, measurement this can be used novel folding be small size.
