Description

A multi-purpose telescopic ruler

technical field

The utility model relates to a multipurpose telescopic ruler.

Background technique

A ruler is used to measure length and is widely used in mathematics, surveying, engineering and other disciplines. The function of a protractor is used to measure angles, and a spirit level is used to measure levels. The three have different functions, but in the process of use in decoration, construction engineering, teaching and other fields, the three are often inseparable. It is very inconvenient to use, carry and store multiple tools, and it takes more money to purchase multiple tools. Cost, the manufacture of multiple large quantities of tools also causes waste of material resources. The utility model is a multi-functional and multi-purpose telescopic straight ruler for measuring angles and leveling, which can well solve the above-mentioned existing problems. The utility model has multiple functions and complete functions, and has broad application prospects.

Utility model content

The utility model makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide a multi-purpose telescopic ruler, which can not only extend the range of measuring length, but also measure angles and measure levels.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is: a multi-purpose telescopic ruler, including a telescopic ruler, the telescopic ruler includes a plurality of segments that can be nested and stretched, and the two sides of the ruler are both Dimension lines and digital marks are provided, and two sets of springs are arranged on the end of the set of rulers, and marbles are connected to both ends of the springs. diameter of the through hole, the end of the outermost ruler is not provided with a spring, the entrance of the innermost ruler is not provided with a through hole, the end of the outermost ruler is hinged with a protractor, the protractor The external dimension is the same as that of the outermost sleeve ruler, and a 360° angle scale line is arranged on the surface of the joint of the sleeve ruler and the protractor.

Further, an angle observation hole is provided at the hinge joint between the protractor and the sleeve ruler, and a frame of the observation hole is flush with the 360° angle scale line when the protractor rotates.

Further, the two sides of the protractor are provided with dimension lines and number marks.

Further, a level tube is provided in the middle of the side wall of the outermost sleeve, and the level tube includes a transparent sealing tube containing liquid, and air is left in the sealing tube.

Compared with the prior art, the utility model has the following beneficial effects:

1. One foot is multi-purpose and has various functions;

2. Simple measurement and accurate data;

3. Economical and economical, saving investment;

4. Simple and lightweight, easy to carry.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Description of drawings

Fig. 1 is a structural schematic diagram of an embodiment of the utility model.

Among the figure: 1-telescopic ruler, 11-through hole, 12-angle observation hole, 13-angle scale line, 14-dimension line, 2-protractor, 3-level pipe.

Detailed ways

Embodiment 1: As shown in Figure 1, a kind of multi-purpose telescopic ruler comprises telescopic ruler 1, and described telescopic ruler 1 comprises six nestable telescopic rulers, and both sides of described ruler are provided with Dimension line 14 and digital identification, two groups of springs are arranged on the end of the ruler, the two ends of the springs are connected with marbles, and the two walls of the entrance of the ruler are provided with holes with a diameter smaller than the outer diameter of the marbles. The through hole 11 of the outermost layer ruler is hinged with a protractor 2, the external dimensions of the protractor 2 are the same as the outermost layer ruler, and both sides of the protractor 2 are provided with dimensions Lines and digital marks, the surface of the hinged part of the sleeve ruler and the protractor 2 is provided with a 360° angle scale line 13.

In this embodiment, an angle viewing hole 12 is provided at the hinged center of the protractor 2 and the ruler, and a frame of the viewing hole 12 is flush with the 360° angle scale line when the protractor rotates. In order to observe the angle no matter what material the protractor is made of.

In this embodiment, the middle part of the side wall of the outermost sleeve ruler is provided with a level tube 3, and the level tube 3 includes a transparent sealed tube containing a liquid, and air is left in the sealed tube, and the liquid is glycerin or Alcohol.

In the implementation of the utility model, when measuring the length, visual inspection needs to measure the approximate length of the object, stretch the telescopic ruler 1, and measure its length. When measuring the angle, the telescopic ruler is balanced with a side of the measured angle, and the amount The dial of the square is balanced with the other side of the measured angle, and the value of the angle to be measured can be directly observed through the angle observation hole 12, and the reading of the center frame of the angle ruler observation hole is flush with the 360° angle scale line is the measured angle. When measuring the level, center the air bubble in the vial, and use the telescopic ruler as the horizontal line to determine the level of the measured or corrected object or straight line.

The above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
