Abstract

The utility model discloses a caliper, comprising a main ruler and two clamping blocks; wherein a surface of a sidewall of the main ruler is provided with scale, an upper end face of the main ruler is provided with a sliding chute; a lower end of the each clamping block is provided with a sliding block matched with the sliding chute, i.e., the clamping block is matched and connected with the sliding chute on the main ruler through the sliding block, and the two clamping blocks are arranged symmetrically; the each sliding block is provided with a screwed hole used for installing a positioning screw in a vertical direction; the sliding chute is a trapezoid groove of which an opening is less than a bottom edge, the sliding block is a trapezoid sliding block matched with the sliding chute; and finger pressing ends of the two clamping blocks are provided with arc-shaped recesses. According to the caliper of the utility model adopting the above technical scheme, a user first places a workpiece needing to the measured between the two clamping blocks, then urges the two clamping blocks to clamp the workpiece by pressing the arc-shaped recesses on the clamping blocks through fingers, and rotates the positioning screws on the clamping blocks, so as to realize positioning for the clamping blocks, at the moment, the user can read the scale value.

Description

A kind of slide calliper rule

Technical field

The utility model relates to a kind of survey instrument, particularly a kind of slide calliper rule.

Background technology

Now people in measuring right cylinder or aperture, often can use vernier caliper such accurately measure chi; but the cost height of vernier caliper; and difficult in maintenance, and our measurement data of needs only need be accurate to millimeter sometimes, like this with some waste of vernier caliper.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of slide calliper rule.

For reaching above purpose, be achieved through the following technical solutions:

A kind of slide calliper rule comprise: main scale and two fixture blocks; The main scale sidewall surfaces is processed with scale, and the upper surface is processed with chute; The fixture block lower end is provided with the slide block that cooperates with chute, and namely fixture block is connected by slide block and main scale upper hopper chute, and two fixture blocks are for being symmetrical arranged; Be processed with on the slide block vertical direction for the threaded hole that dog screw is installed; Chute be opening less than the trapezoidal groove on base, slide block is the trapezoidal slide block with chute coupling; Two fixture block finger presses ends are provided with arc-shaped recess;

The arc-shaped recess place is provided with rubber layer on the fixture block, is convenient to user's finger presses;

Adopted the utility model user of technique scheme at first will need measuring workpieces to be positioned between two fixture blocks, impel two fixture block clamping work pieces by the arc-shaped recess on the finger presses fixture block then, rotate the dog screw on the fixture block then, realization is to the location of fixture block, and this person of being to use gets final product reading.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.

Among the figure: 1, main scale, 2, fixture block, 3, chute, 4, slide block, 5, dog screw, 6, arc-shaped recess.

Embodiment

A kind of slide calliper rule as depicted in figs. 1 and 2 comprise: main scale 1 and two fixture blocks 2; Main scale 1 sidewall surfaces is processed with scale, and the upper surface is processed with chute 3; Fixture block 2 lower ends are provided with the slide block 4 that cooperates with chute 3, and namely fixture block 2 is connected by slide block 4 and main scale 1 upper hopper chute 3, and two fixture blocks 2 are for being symmetrical arranged; Be processed with on slide block 4 vertical directions for the threaded hole that dog screw 5 is installed;

Chute 3 be opening less than the trapezoidal groove on base, slide block 4 is the trapezoidal slide block with chute 3 coupling;

Two fixture block 2 finger presses ends are provided with arc-shaped recess 6, and arc-shaped recess 6 places are provided with rubber layer on the fixture block 2, make things convenient for the user to press fixture block;

Adopt the utility model user of technique scheme at first will need measuring workpieces to be positioned between two fixture blocks 2, impel two fixture block 2 clamping work pieces by the arc-shaped recess 6 on the finger presses fixture block 2 then, rotate the dog screw 5 on the fixture block 2 then, realization is to the location of fixture block 2, and this person of being to use gets final product reading.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art are not in breaking away from the technical solutions of the utility model scope, appeal the equivalent embodiment that the technology contents that discloses is made a little change or is modified to equivalent variations when utilizing, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
