Abstract

The utility model provides a thickness gauge for measuring thickness of objects, consisting a scaled outer shell, a main shaft and an upper flap and a lower flap, which are all connected, wherein the main shaft which can move up and down is inserted into a cavity of the scaled outer shell from one end of the scaled outer shell and sheathed with the scaled outer shell; the lower end of the outer shell is symmetrically provided with grooves which are provided inside with flaps, the upper and the lower flaps which can be opened and closed are movably connected by a bolt, the lower end of the lower flap is fixedly connected with the lower end of the outer shell. When the utility model is used, a force giver exerts force on the upper end of the main shaft, and the upper and the lower flaps can be opened to a certain position by the drive of the main shaft, the thickness gauge is moved to contact the measuring object, thereby reaching the intensions that the thickness gauge is in the alignment with the measuring object and the thickness of the object can be more accurately measured; the thickness gauge has the advantages of simple structure, easy manufacture, common raw material and low cost, and can conveniently measure the thickness of the object and be used in any condition.

Description

The thickness chi

Technical field

The utility model relates to a kind of surveying instrument, especially a kind of thickness chi that has scale, can make things convenient for accurate Measuring Object thickness.

Background technology

At present Measuring Object thickness major part is to adopt an end of the zero graduation alignment testee of chi, then at other end reading, or detects with ultrasound wave, electromagnetic wave thicknessmeter.But when a lot of objects used general chi to measure, zero graduation was difficult to align with the object end, caused difficulty to detecting thickness.Moreover ultrasound wave, electromagnetic wave thicknessmeter structure are comparatively complicated, element is accurate, and cost is higher, also is particular about condition during measurement, is unfavorable for popular the use.

Summary of the invention

The zero graduation deficiency with ultrasound wave, electromagnetic wave thicknessmeter that is difficult to align when overcoming general chi Measuring Object with the object end, the utility model provides a kind of thickness chi, this thickness chi zero graduation can not only make things convenient for the testee end and aligns, and simple in structure, with low cost.

The technical scheme in the invention for solving the above technical problem is: the thickness chi is connected by the shell that has scale, main shaft, last flap and following flap and forms.Architectural feature is: main shaft inserts its cavity socket at graduated shell one end, can move up and down, shell lower end symmetrical grooving is provided with flap, and expansible, the last flap that folds, following flap connect by bolt is movable, and following flap lower end and shell lower end are fixedly connected.

Main shaft, the shell that has a scale can be that single-unit or more piece connect.

Last flap, following flap are made up of movable connection of two joints respectively.

When Measuring Object, application of force person applies power to the main shaft upper end, when making upper and lower flap open the arrival certain position by the main shaft power transmission, mobile thickness chi contacts with testee, aligns thereby make it to reach with the testee end, can more accurately measure the purpose of object thickness, carry out reading, obtain a result.

The beneficial effects of the utility model are: the thickness of Measuring Object easily; Simple in structure, easily manufactured; Material is common, and is with low cost, conveniently using under the condition arbitrarily.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 2 is a side view of the present utility model.

Fig. 3 is the utility model vertical section structure synoptic diagram.

Fig. 4 is the structural representation of the utility model flap when opening.

Fig. 5 is the vertical section structure synoptic diagram of the utility model embodiment.

1. main shafts among the figure, 2. shell, 3. snib, 4. bolt is 5. gone up flap, and 6, flap 7, testee down.

Embodiment

In Fig. 1, main shaft 1 stretches into its cavity socket from band scale shell 2 one ends, can move up and down, and makes volume minimum so that penetrate testee.

In Fig. 2, band scale shell 2 lower end symmetrical grooving, the size of fluting will satisfy opening of last flap 5 and following flap 6 and fold.Flap 6 was two joints under last flap 5 reached, by 4 movable connections of bolt.

In Fig. 3, main shaft 1 lower end connects by bolt 4 activities with last flap 5 upper ends, and two joints are gone up flap 5 lower ends and connected by bolt 4 activities flap 6 upper ends down with two joints respectively, and following flap 6 lower ends and scale shell 2 lower ends are fixedly connected by bolt 4.

In use, the thickness chi passed or near testee 7, being exerted pressure down in main shaft 1 upper end pushes away, and makes flap 5, stressed opening of 6 while of time flap, sees Fig. 4, and main shaft 1 moves down when touching snib 3, pushes away under stopping to make whole chi to be reached rock-steady structure.Mobile scale shell 2 aligns with the testee end; Read the reading of scale shell 2 scales, by calculating the thickness of testee.See Fig. 5.
