Also referring to Fig. 1 to Fig. 3, now slide measure provided by the utility model is illustrated.The slide measure, The vernier 200 being slidably matched including main scale 100 and with the main scale 100, it is characterised in that:The upper end of main scale 100 is set There is the first measuring jaw 110, the upper end of vernier 200 is provided with the second amount with the conjunction measuring outside dimension of the first measuring jaw 110 Pawl 210, the lower end of main scale 100 are provided with the 3rd measuring jaw 120, and the lower end of vernier 200 is provided with and the 3rd amount The conjunction measuring pitch-row of pawl 120 and the 4th measuring jaw 220 in aperture, the lower end of the 3rd measuring jaw 120 and the 4th measuring jaw 220 are down Cone.The first measuring jaw 110 and the second measuring jaw 210 of the slide measure are consistent with the usage of traditional slide measure to be used for external chi Little progress row effectively measures, and is arranged at the 3rd measuring jaw 120 below main scale 100 and vernier 200 and the 4th measuring jaw 220 for coordinating The pitch-row between holes is measured, tradition eye observation holes center and then the inaccuracy with kind of calliper can be avoided, avoided What the appearance of obvious errors, the 3rd measuring jaw 120 of the present apparatus and the lower end of the 4th measuring jaw 220 were set can be right to cone 221 It should stretch into hole to be measured, by the contact that the outer surface of inverted cone 221 is stable with hole formation, pitch-row is carried out to hole Measurement, accurate positioning, scale error caused by avoiding hole centralized positioning inaccurate.
Slide measure provided by the utility model, compared with prior art, the utility model structure statement of account, surveyed in outside dimension , can be fast by the 3rd measuring jaw and the 4th measuring jaw of the inverted cone shape being correspondingly arranged on main scale and vernier on the basis of amount The fast measurement for accurately carrying out holes centre-to-centre spacing, not only embodies the convenience of measurement, while also ensure that the measurement essence of pitch-row Degree, has good using effect and extensive promotional value.
As further optimization, also referring to Fig. 1 and Fig. 3, one as slide measure provided by the utility model Kind of embodiment, the first measuring jaw 110 are set with the specular of the second measuring jaw 210, the 3rd measuring jaw 120 with it is described The specular of 4th measuring jaw 220 is set.First measuring jaw 110 and the specular of the second measuring jaw 210 are set, and its outside dimension is consistent, energy Good contact is enough formed with object under test by medial surface, is easy to measure the external dimensions of general object.3rd amount For the measuring jaw 220 of pawl 120 and the 4th also in the form of specular is arranged, outside dimension is consistent, can easily carry out the measurement of pitch-row, The precision of positioning and measurement is obtained for sound assurance.
As further optimization, referring to Fig. 1, one kind specific implementation as slide measure provided by the utility model Mode, main scale 100 are provided with the first scale, and the vernier 200 is provided with the 3rd quarter corresponding with the first scale of the main scale 100 Degree, when first measuring jaw 110 is bonded with the second measuring jaw 210, the zero graduation line pair of first scale and the 3rd scale Together.The first scale on main scale 100 is used to measure length, while the first scale and the 3rd scale are used cooperatively to enter The measure of row accurate-size, the application method of in general slide measure is same as, when the first measuring jaw 110 and the second measuring jaw 210 are mutual During fitting, the first scale aligns with the zero graduation line of the 3rd scale, and now reading is 0.
As further optimization, also referring to Fig. 1 and Fig. 3, one as slide measure provided by the utility model Kind embodiment, the 3rd measuring jaw 120 and the 4th measuring jaw 220 include inverted cone 221 and flat part 222, the rounding Cone 221 is connected by flat part 222 with the bottom surface of vernier 200, and the lateral surface of the inverted cone 221 is provided with along the inverted cone The second scale that the short transverse of body 221 is set.The setting of flat part 222 can realize inverted cone 221 and main scale 100 or The effect that vernier 200 is connected, avoid inverted cone 221 be directly arranged at caused by main scale 100 or vernier 200 with it is to be measured The phenomenon of location conflicts between metering-orifice, it ensure that the convenience of measurement.The pointed end of inverted cone 221 is set, so most The external diameter respective value of lower end is minimum, and the external diameter respective value of its top is maximum, so the second scale sequentially becomes big from bottom to top.Together When the second scale aperture for being used for device to hole external diameter carry out dimensional check, there is good detection to act on, be easy to ensure later stage peace The accuracy of dress.
As further optimization, also referring to Fig. 1 to Fig. 2, one as slide measure provided by the utility model Kind embodiment, vernier 200 is sheathed on the outside of main scale 100, and the position of the first scale is corresponded on the vernier 200 Provided with opening, the vernier 200 is additionally provided with the depth being slidably matched with the cell body of the main scale 100 away from the side of the first scale Chi 230.The matching relationship of vernier 200 and main scale 100 is same as traditional slide measure, at the same the back of vernier 200 set with master The depth gauge rule 230 that the cell body of chi 100 is slidably matched can be measured easily to hole depth, have good practicality.
As further optimization, referring to Fig. 1, one kind specific implementation as slide measure provided by the utility model Mode, the top of vernier 200 are provided with the trip bolt 130 for being used for holding out against with the upper surface of main scale 100.During measurement, work as operator , can be by being arranged at the fastening spiral shell of the top of vernier 200 when the location of member is not easy to carry out direct reading to slide measure Nail 130 is locked the relative position of vernier 200 and main scale 100, is entered again after then slide measure is taken out at determinand The reading of line number value, it is easy to ensure accuracy of reading to greatest extent.
The utility model structure statement of account, on the basis of outer dimensional measurement, by being correspondingly arranged on main scale and vernier 3rd measuring jaw of inverted cone shape and the 4th measuring jaw, the measurement of holes centre-to-centre spacing can be fast and accurately carried out, is not only embodied The convenience of measurement, while the measurement accuracy of pitch-row is also ensure that, there is good using effect and extensive promotional value.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model Within the scope of shield.
