Description

new surveying square

technical field

The utility model relates to the field of surveying and mapping technical tools, in particular to a novel surveying and mapping square.

Background technique

An angle ruler is a commonly used surveying and mapping tool in building construction. Its main structure is usually composed of two straightedges hinged at one end; when in use, the straightedge is used as a reference ruler, and the other ruler rotates around the hinge point as a measuring ruler. Due to their own size limitations, the existing various angle rulers are not capable of measuring the angle between remote objects and marking lines. Especially when the length of the line to be drawn is much larger than the length of the measuring ruler itself, continuous and accurate marking operations cannot be performed.

Contents of the invention

In order to solve the problems of remote angle measurement and marking, the utility model provides a new surveying square.

The technical scheme of the utility model is: a new type of surveying and mapping angle ruler, including a ruler, a protractor, a hinge shaft, a length mark and an angle mark, and is characterized in that it includes two rulers, and the two rulers are hinged by a hinge shaft. One of the straightedges is provided with a protractor and a length mark, the center of the protractor is located on the center of the hinge shaft, the angle mark is set on the protractor, and the axis of the other straightedge is provided with an angle indicator mark. The front ends of the two straightedges are Laser lamps are arranged on the top, and grooves are arranged on the front and back sides of the two rulers, and a rotating shaft is arranged in the groove, and the steel nail is connected with the groove through the rotating shaft.

The rotating shaft is provided with a spring that presses the steel nail and makes the steel nail be located in the middle of the groove.

Both ruler and protractor are made of steel.

The beneficial effects of the utility model are: the measurement between remote objects can be measured, the steel nails can be marked on the surface of hard objects such as rocks or concrete, and the steel nails can be received inside the ruler to avoid stabbing workers, which is convenient and practical.

detailed description

Example 1

As shown in Fig. 1, Fig. 2 and Fig. 3, a new type of surveying and mapping square includes a ruler 1, a protractor 2, a hinged shaft 3, a length mark 4 and an angle mark 5, and is characterized in that: two straightedges 1, two The straightedges 1 are hinged by hinge shafts 3, and one of the rulers 1 is provided with a protractor 2 and a length mark 4, and the center of the protractor 2 is located at the center of the hinge shaft 3, and the angle mark 5 is set on the protractor 2. An angle indicator 6 is arranged on the axis of a ruler 1, a laser light 8 is arranged on the front fronts of the two rulers 1, and a groove 9 is arranged on the backs of the front ends of the two rulers 1. A rotating shaft 10 is provided, and the steel nail 7 is connected with the groove 9 through the rotating shaft 10 .

Wherein, the rotating shaft 10 is provided with a spring that compresses the steel nail 7 and makes the steel nail 7 located in the middle of the groove 9, and both the ruler 1 and the protractor 2 are made of steel.

The beneficial effects of the utility model are: the measurement between remote objects can be measured, the steel nails can be marked on the surface of hard objects such as rocks or concrete, and the steel nails can be received inside the ruler to avoid stabbing workers, which is convenient and practical.
