Description
Technical field
The utility model belongs to measures apparatus field, relates to a kind of accurate vernier universal bevel protractor.
Background technology
The vernier bevel protractor of current production, because the cutting edge of ruler is wider, lower with angle precision during light transmission method detection part, thus reduce the accuracy of measurement of part, observe to user simultaneously and bring very big inconvenience.Aborning, measure in the groove that part usually will be inserted in the tip of ruler, the angle in parts groove is less than 45 ° sometimes, and the ruler tip of existing vernier universal bevel protractor is 45° angle, and angle is excessive, needs to improve.The interconnective side of last fanning strip, angle square and ruler, easily produces wearing and tearing in use, reduces the life-span of universal protractor.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of accurate vernier universal bevel protractor, user can be made by light transmission method pin-point reading, also can reduce the wearing and tearing that fanning strip, angle square and ruler side in use cause, expand the scope of application of vernier universal bevel protractor simultaneously.
To achieve these goals, the technical scheme that the utility model is taked is:
Described accurate vernier universal bevel protractor, the reading mechanism comprising ruler, square, fanning strip and be fixed on described fanning strip, described fanning strip is removably mounted on described ruler or described square by fixture block, described square is removably mounted on described ruler by fixture block, described reading mechanism comprises main scale, be fixed on vernier on described fanning strip and brake head, described ruler and described square all have edge of a knife shape side, and described fanning strip and described square all have flute profile side; Have the inclined-plane matched with described edge of a knife shape side inside the groove of described flute profile side, the trench bottom of described flute profile side does not contact with between the cutting edge of described edge of a knife shape side; The angle at the tip of described ruler is not more than 30 °
Described main scale is contacted by the stepped edge matched with described vernier, and the scale face that has of described vernier and described main scale is positioned at same plane.
Described cutting edge passivation is fillet.
Adopt technique scheme, by adopting edge of a knife shape side, its edge width is little, and user is higher with certainty of measurement during light transmission method detection part; Decrease each parts of ruler, square and fanning strip and be connected side loss in use; Increase the scope of application of vernier universal bevel protractor with the ruler tip that angle is less simultaneously.
The scale face that has of vernier and main scale is positioned at same plane, makes reading accurately convenient.The step edge cooperatively interacted contributes to ensureing to combine between vernier and main scale to put in place when mounted, realizes having scale face coplanar.
Cutting edge passivation is fillet, ensures security, also makes cutting edge more durable.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
As shown in Figures 1 to 6, the utility model provides a kind of accurate vernier universal bevel protractor, the reading mechanism comprising ruler 6, square 5, fanning strip 3 and be fixed on fanning strip 3.Reading mechanism comprises and is arranged on vernier 2 on fanning strip 3 and brake head, and the main scale 1 be slidably matched with vernier 2; Main scale 1 is while be fixed with base chi.Fanning strip 3 can be arranged on ruler 6 or square 5 by fixture block 4, and square 5 also can be arranged on ruler 6 by fixture block 4.Unclamp the separable each parts of fixture block 4 or make connected components relative sliding.
Fanning strip 3 is arranged on ruler 6 or square 5 as required during use, is attached to base chi and treats in angle measurement.Fanning strip 3 is moved along main scale 1, the side of fanning strip 3, ruler 6 or square 5 is fitted to and treats angle measurement another side, reading is being carried out to the main scale 1 in reading mechanism and vernier 2.
The angle at the tip 8 of ruler 6 is not more than 30 °, and this is the design in order to do for needing to insert element groove place by most advanced and sophisticated 8 when measuring, and compared with being the vernier universal bevel protractor of 45 ° with existing nothing most advanced and sophisticated 8 or most advanced and sophisticated 8 angles, the scope of application is wider.
The wearing and tearing of opposite side during in order to improve the precision of measurement and reduce use, ruler 6 and square 5 all have edge of a knife shape side 7, and fanning strip 3 and square 5 also all have flute profile side 9.When installation fanning strip 3, or when being arranged on ruler 6 by square 5, edge of a knife shape side 7 is connected with fixture block 4 with flute profile side 9.Have the inclined-plane matched with described edge of a knife shape side 7 inside the groove of flute profile side 9, the trench bottom of described flute profile side 9 does not contact with between the cutting edge of described edge of a knife shape side 7.Between such edge of a knife shape side 7 and flute profile side 9, stable connection also energy relative sliding, can not cause wearing and tearing to cutting edge in sliding process simultaneously, can protect the cutting edge of edge of a knife shape side 7, increase the life-span of vernier universal bevel protractor.
The scale face that has of vernier 2 and main scale 1 is positioned at same plane after mounting, and the edge that main scale 1 and vernier 2 contact is the ledge structure matched.Main scale 1 and vernier 2 are combined with and help locate so when mounted, ensure to combine between vernier 2 and main scale 1 to put in place.The two has scale face to be positioned at same plane, prevents the collimation error, accurately convenient during user's reading.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
