Abstract

The utility model discloses a universal angle measuring instrument. The utility model comprises a circular arc-shaped main scale 8 and a vernier scale 7 which can slide long the external side of the circular arc of the main scale, twp sets of complementary angle reading scales are arranged on the main scale 8, a main scale frame 4 is fixedly connected with a vernier scale frame 5 through a pin shaft 2, the lower end of the main scale frame 4 and the lower end of the vernier scale frame 5 are provided with detachable measuring angle squares 1, and a locking head 6 is arranged on the vernier frame. The angle measuring instrument adopts a scissor sheet structure and has the advantages of reasonable structure, convenient combination, high measuring efficiency and high accuracy. The utility model can measure an internal angle as well as an external angle, when the utility model is added with a certain fitting, the verticality of a part can be completed.

Description

Omnipotent angel measuring instrument

The utility model relates to a kind of measurer of the usefulness that takes measurement of an angle.

Bevel protractor subassembly commonly used in the prior art is many, complex structure, and reading is not directly perceived when taking measurement of an angle, thereby manufacturing cost is higher, and measuring accuracy is not high, and gauger's technical merit, skilled operation degree all had certain requirement.Chinese patent application CN87208122U discloses a kind of " special-shaped universal protractor ", it is angle increase with the fanning strip plate face of existing bevel protractor, make it be convenient to be connected with other annex, can the measurement axis class, the position of hole type parts and other part, but single when being used to take measurement of an angle speed still fast inadequately, efficiency of measurement is not high.

The purpose of this utility model is intended to obtain the higher angel measuring instrument of a kind of efficiency of measurement, and is easy to use, simple to operate, both can measure the exterior angle and also can measure interior angle.

For achieving the above object, the technical solution that the utility model proposes is:

A kind of omnipotent angel measuring instrument, it comprises: circular arc main scale 8 and the vernier scale 7 that can slide along the main scale circular arc outside, the read text scale that the angle of two groups of complementations is arranged on main scale 8, main scale frame 4 is connected by bearing pin 2 with vernier scale frame 5, and main scale frame 4 is dismountable measurement angle square 1 with vernier scale frame 5 lower ends.

Measure on the angle square 1 screw hole 9 that matches with main scale frame 4 or vernier scale frame 5 is arranged.

There is limited block 11 main scale 8 ends.

Locking head 6 is arranged on the vernier scale frame 5.

Below in conjunction with accompanying drawing the utility model is further described:

Figure 1 shows that the synoptic diagram when the omnipotent angle detector of the utility model is measured the exterior angle.

Figure 2 shows that the synoptic diagram when the omnipotent angle detector of the utility model is measured interior angle.

Shown in Figure of description, the utility model adopts the scissors slice structure, and promptly main scale frame 4 and vernier scale frame 5 are by bearing pin 2 hinge joints.Vernier scale 7 just can slide along the external arc of main scale 8 like this, the read text scale that two groups of angle complementations are arranged on the main scale 8, one group for measuring the reading of interior angle, another group is for measuring the reading at exterior angle, and the locking head on the vernier scale frame 5 can be fixed on vernier on the main scale, and the measurement angle square 1 of main scale frame 4 and vernier scale frame 5 lower ends is detachable, 3 is gib screw, when measuring the exterior angle, measure with the measurement angle square 1 of main scale frame 4 and vernier scale frame 5 lower ends, as Fig. 1.When measuring interior angle, see Fig. 2, measure angle square 1 with two and disassemble, measure with main scale frame 4 and vernier scale frame 5, the measurement angle square 1 that removes can be screwed in the main scale frame 4 and vernier scale frame 5 outsides, and measuring on the angle square 1 has the screw hole 9 that matches with main scale frame 4 or vernier scale frame 5.When this measuring instrument is increased certain accessory, as increasing by a right angle cushion block 10 in measurement angle square 1 lower end that links to each other with main scale frame 4, right-angle side of right angle cushion block 10 and the side adjacency of measuring angle square 1, this measuring instrument also can doublely be done the detection of parts verticality like this.

The utility model is owing to adopt the scissors slice structure, easy to use, applicable to measurement in testing process such as various mechanical component, carpenter, pincers worker to angle, this angel measuring instrument is rational in infrastructure, combined and instant, both can measure interior angle and also can measure the exterior angle, and the double detection of doing the parts verticality of energy, efficiency of measurement height, precision height.
