Multifunctional vernier bevel protractor

Abstract

The invention discloses a multifunctional vernier bevel protractor. The multifunctional vernier bevel protractor comprises a depth vernier, a bevel protractor and a main ruler, wherein the depth vernier and the bevel protractor are both installed on the main ruler. The novel multifunctional vernier bevel protractor is integrated with advantages of a universal bevel protractor, a depth vernier caliper and an edge square, can simultaneously measure the depth dimension, angle and linearity of a processing surface, can also be individually used as the depth vernier caliper, the universal bevel protractor or the edge square, and realizes multiple purposes through one ruler.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, in particular to a multifunctional vernier angle ruler. Background technique [0002] In the daily production of the fitter, it is often necessary to put forward requirements for depth, angle and straightness. At this time, the traditional measurement method is to measure the straightness with a knife edge ruler, then measure the depth dimension with a depth ruler, and then measure the angle with an angle ruler. The measurement is more cumbersome, and there are more measuring tools to be prepared, which wastes more time. [0003] At present, there are also some multifunctional measuring tools that can be used for measurement, such as: Chinese patent CN201520377547.3 discloses a new universal angle ruler, including a universal angle ruler, a vernier caliper, and a clamping block. A main ruler, a first vernier, a brake head, and a base ruler, the vernier caliper is composed of a sec...

[0002] In the daily production of the fitter, it is often necessary to make requirements for depth, angle and straightness. At this time, the traditional measurement method is to measure the straightness with a knife-edge ruler, then measure the depth with a depth ruler, and then measure the angle with an angle ruler. The measurement is cumbersome, and there are more measuring tools that need to be prepared, which wastes more time

[0003] At present, there are also some multifunctional measuring tools that can be used for measurement, such as: Chinese patent CN201520377547.3 discloses a new universal angle ruler, including a universal angle ruler, a vernier caliper, and a clamping block. A main ruler, a first vernier, a brake head, and a base ruler, the vernier caliper is composed of a second main ruler, an outer measuring claw, a stopper, and a second vernier, and the universal angle ruler and the vernier caliper are connected by a clamping block, This patent can only measure angle and height at the same time; Chinese patent CN201420801904.X discloses a precision vernier universal angle ruler, including a ruler, a square, a fan-shaped plate and a reading mechanism fixed on the fan-shaped plate. The fan-shaped plate passes through the clamping block It is detachably installed on a ruler or a square, and the square is detachably mounted on the ruler through a clamping block. The reading mechanism includes a main ruler, a vernier and a brake head. Both the ruler and the square have knife-edge-shaped sides. Both the fan-shaped plate and the square have groove-shaped sides; the inner side of the groove-shaped side has a slope that matches the knife-edge-shaped side, and there is no contact between the bottom of the groove-shaped side and the cutting edge of the knife-edge-shaped side; The angle of the tip of the straightedge is not more than 30°, this patent can only measure the angle and straightness at the same time
