Abstract

The utility model relates to a simple universal dividing caliper, which is a measuring instrument used for measuring various angles. An indicating rule with a vernier scale is combined on the central shaft of a dividing disc, another two vertical and horizontal rules are connected to one end of the indicating rule and the dividing disc with the method of riveted connection, each end of the two rules are combined together by the riveted connection of a shaft center, and the dividing caliper can be steadily arranged on a circular arc surface by a slot gauge base to make the special dividing realized.

Description

Simple universal dividing calipers

The utility model provides a kind of easy polynary diagraph, and this diagraph can be measured different and special angle.

The simple and easy indexing attachment of commonly using at present only can be done general outer angular indexing function, and can't do interior angle and diversified calibration work;

Shown in first figure (one of figure one, two, three), simple and easy indexing attachment for several versions, they all are to utilize a gage to take exercises in the axle center of index plate and come calibration by the linear edge and the gage edge angle of index plate, perhaps, but only provide the gage of a radial displacement, equally, this kind indexing attachment can only provide general simple outer angular indexing work, and can't measure interior angle and have other function.

Therefore the purpose of this utility model be at commonly use at present simple and easy indexing attachment be beyond one's reach in angular indexing do an innovation improvement.The utility model is except can also providing outer angular indexing for the interior angular indexing, more can make the activity point of view set pattern uses, in addition, in between indication gage and index plate, be provided with an angle fixing device, make the Universal, simple diagraph can be with angle orientation, and be provided with geosynclinal block rule base in its bottom, diagraph be placed on circular arc, pipe and the inclined-plane stably by means of the groove of geosynclinal block rule or skewed slot; In addition, at indication gage and each delineation of vertical, horizontal gage vernier and size scale are arranged, to provide accurately and measurement of angle fast and data read.

For making the auditor understand flesh and blood of the present utility model fully, as follows according to graphic detailed description the utility model now:

Graphic brief description:

First figure: commonly use the diagraph structural representation.

Second figure: three-dimensional exploded view of the present utility model.

The 3rd figure: of the present utility model just, backplan.

The 4th figure: the utility model is implemented illustration (interior angular indexing, outer angular indexing, vertical angle measurement).

The 5th figure: of the present utility model another implemented illustration.

With reference to second, shown in three figure, the utility model Universal, simple diagraph 1 is to utilize an indication gage 10 and pass through an axle center rivet 11, indication gage 10 is riveted on the center of index plate 20, other has a vertical gage 30, an and horizontal gage 40, each is by an axle center rivet 31,41 will be vertical,

horizontal gage

30,40 are riveted on each end of indication gage 10 and index plate 20, and it is vertical, level two

gages

30,40 the other end utilizes an axle center rivet 50 that it is combined again, makes in the utility model reaches by means of the effect of connecting rod, the calibration measurement effect of outer angle.

And this index plate 20 is quadrilateral, and it is a hypotenuse on one side, be in order to cooperate vertical gage 30 as taking measurement of an angle use, and establish a circular arc in the index plate 20 and run through groove 21, and in this groove 21, cooperate a round end and stay dihedral flat head bolt 60, the circular arc that this bolt 60 passes index plate 20 runs through groove 21 and combines with adjustment nut 61 that an end face has a tapering, read the data that take measurement of an angle with the measured angle of fixed vertical gage 30 and horizontal gage 40 and by indication gage 10, undermine the precision of index plate 20 to avoid both to produce friction and establish a packing ring 62 between adjustment nut 61 and the index plate 20, and can keep a fixing friction force.

In addition, index plate 20 1 ends add a thicker cover packing ring 32 with 31 riveted joints place of vertical gage 30 axle center rivets, and indication gage 10 is then established thin cover packing ring 42 with axle center rivet 41 riveted joints place of horizontal gage 40; And the cooperation by above each member and motion and can be used for the ordinary surveying of inside and outside angle and tool pluralistic function.

And shown in the 4th figure (one of figure four, two, three), be several enforcement figure of the present utility model, this indication gage 10 all utilizes an axle center to be embedded in the appropriate location with index plate 20 and vertical,

horizontal gage

30,40, and make moving of one gage can both draw other gage, and utilize the tetragonal structure of index plate 20 to reach as interior angular indexing (A) and outer angular indexing (B) and the scalable mobile right angle observation of gage (C1), (C2) as shown in one of figure four; In addition, its vertical,

horizontal gage

30,40 also can inwardly shrink and be the surveying work of angle shape (C3) in order to general outer angular indexing, and its vertical,

horizontal gage

30,40 and have size scale and can be as the general measure instrument.

Consult the 5th figure, another implements illustration (one of figure five, two) the utility model, and vertical as shown in the figure,

horizontal gage

30,40 visual demands and be designed to bending are measured with the special angle that adapts to different demands as F type or Contraband type even difformity; In addition, a geosynclinal block is set advises 70 bases and combine with index plate 20, these geosynclinal block rule 70 be reserved with groove 71 with Shape groove 72, it can pass through

Shape groove 72 steadily is positioned over Universal, simple diagraph 1 on circular arc 2 or pipe 3 and the inclined-plane 4 and takes measurement of an angle.

For ease of more detailed expression other function and usage of the present utility model, see also the annex one in the application explanation and the graphic explanation of annex two.

In sum, the utility model is with the design and the ingenious structural design of its precision, make the integrally-built combination of Universal, simple diagraph after the improvement and uncomplicated, but the effect that it can reach, but at all no less than the diagraph of commonly seeing, DATA REASONING and special angle (as oblique angle, acute angle, right angle etc.) such as various inside and outside angles are measured, and its structure is at first creating and have much practicality.
