Embodiment
Embodiment 1
A kind of Portable angle chi, see in accompanying drawing 1 to accompanying drawing 4, figure: the first base chi 1, first bearing pin 2, graduated scale 3, reading limit 301, secondary chi 4, claw 401, datum line 402, second base chi 5, second bearing pin 6.
In the present embodiment, main scale is made up of the first base chi 1 and the second base chi 5, and one end of the first base chi 1 and the second base chi 5 is hinged by the second bearing pin 6, the first base chi 1 is hinged with one end of graduated scale 3 by the first bearing pin 2.
Second base chi 5 is hinged with secondary chi 4, and the other end of graduated scale 3 passes the chute on secondary chi 4 and coordinates with slide, and the claw 401 on secondary chi 4 and the space formed between secondary chi 4 are chutes; (claw 401 is processed from the body of secondary chi 4 by the mode of the right punching press again of the Linear cut) height of chute and the thickness of graduated scale 3 match, be beneficial to the smooth and easy slip of graduated scale 3, first base chi 1, second base chi 5 and be with graduated graduated scale 3 to form isosceles triangular structure, graduated scale 3 is as the base of isosceles triangular structure.Feature of the present utility model takes measurement of an angle with the form of isosceles triangle; With the form of isosceles triangle, using isosceles limit (namely the first base chi 1 and the second base chi 5) as measurement limit, use using the graduated scale 3 as base as the form reading value limit, can along with the precision of the increasing raising scale division value of isosceles edge lengths.
First base chi 1 and the hinged central point of graduated scale 3 to be placed in the symmetrical center line of the first base chi 1 and to overlap with the zero graduation of graduated scale 3; Second base chi 5 is placed in the symmetrical center line of the second base chi 5 with the hinged central point of secondary chi 4; First base chi 1 and the isometric setting of the second base chi 5.
First base chi 1, second base chi 5 is connected the rear isosceles triangle type structure forming closed stablity with graduated scale 3 by the first bearing pin 2, second bearing pin 6; First bearing pin 2, second bearing pin 6 can be dismantled; Shown by Fig. 2 is the practical measuring examples of outer corners.
Datum line 402 on secondary chi 4 forms plumbness with the reading limit of rule 3, and the straight line at datum line 402 place is just by the central point of secondary chi 4 and the second base chi 2 jointed shaft.
Assembling process:
First by hinged with the second bearing pin 6 for the head location hole of the first base chi 1, second base chi 5, the first bearing pin 2 is passed through in one end of graduated scale 3 and the first base chi hinged, the other end of graduated scale 3 is inserted in the chute of secondary chi 3 again, just complete assembling.
Use: the relative position of moving sets chi 3 on graduated scale 5, just can read the corresponding scale numerical value of secondary chi 3 scale on graduated scale 5, and this numerical value is exactly the angular values of the angle that the first base chi 1 and the second base chi 2 are formed.
The first base chi 1, second base chi 2 in the present embodiment and rule 3 can free predetermined angulars by the second bearing pin 6; First base chi 1 is connected by the first bearing pin 2 with graduated scale 3, datum line 402 on secondary chi 4 aligns with the scale on rule 3 reading limit 301, by the isosceles triangle formed by the first base chi 1 second base chi 2 and graduated scale 3, complete stable precise angle to measure, structure reaches the object accurately measuring angle.
The utility model is not limited to the structure of secondary chi 4 cited in the present embodiment, as long as there is datum line, is sleeved on the sleeve type structure on secondary chi 4, is also considered as within protection domain of the present utility model.
