Abstract
The utility model discloses an adjustable right-angle ruler. The two ends of a fixed beam are respectively provided with a C-shaped deep groove, a 45-degree angle is formed between each C-shaped deep groove and the fixed beam, each C-shaped deep groove is internally provided with a projecting key, a 45-degree angle is formed between each projecting key and the fixed beam, each C-shaped deep groove is provided with a fixing jackscrew, and two groove-containing rulers are inserted in the C-shaped deep grooves at the two ends of the fixed beam and are screwed by the jackscrews on the C-shaped deep groove. When an object with radians is measured or an obstacle exists at a right-angle position, measurement can be carried out smoothly by adjusting the two right-angle sides.
Description
Technical field
The utility model relates to a kind of try square, the definite adjustable try square of a kind of two right-angle side that says.
Background technology:
Two right-angle sides of selling the various try squares that use in the market are all fixed, and when we measure with radian or when there is ridge in the place at right angle, try square is just not easy to measure, and the resultant error of measurement is also very large.
Summary of the invention:
The purpose of this utility model is the above-mentioned defect of customer service, provides a kind of two right-angle side adjustable try square, can bring facility to vertical angle measurement, has guaranteed precision, because two right-angle sides are detachable, so easy to carry.
The utility model comprises that fixed cross beam, two be with reeded ruler, its design feature is: at the two ends of fixed cross beam, be provided with C moldeed depth groove, and C moldeed depth groove becomes miter angle with fixed cross beam, in C moldeed depth groove, be provided with the key of protrusion, the key protruding also becomes 45 degree with crossbeam, C moldeed depth groove is provided with fixedly jackscrew, in two C moldeed depth grooves with reeded ruler insertion fixed cross beam two ends, with the jackscrew on C moldeed depth groove, holds out against.
The utility model is with reeded ruler to form by fixed cross beam and two, because the ruler of two right-angle sides can move, so if run into while having ridge with radian or in place, right angle as long as regulate right-angle side just can measure smoothly.
The utility model is simple in structure, reasonable in design, has improved the utilization factor of try square.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation:
Embodiment
Below in conjunction with accompanying drawing, be described further.
In Fig. 1, the two ends of fixed cross beam 1 are provided with C moldeed depth groove 3, C moldeed depth groove 3 is with 1 one-tenth 45 degree of fixed cross beam, in C moldeed depth groove 3, be provided with the key of protrusion, the key protruding also becomes 45 degree with crossbeam, C moldeed depth groove 3 is provided with fixedly jackscrew 4, be with reeded ruler 2 to insert in C moldeed depth groove 3, with the fixedly jackscrew 4 on C moldeed depth groove 3, hold out against.
