Embodiment 1

[0027] An embodiment of the present invention provides an inflatable measuring ruler, which is used to measure the length of special environments such as bending and narrowness. The inflatable measuring ruler includes a ruler body and a ruler base, such as Figure 1-2 As shown, the ruler body includes at least two flexible ruler tapes 101 that can be curled. connection, with an air bag 103 in the middle; the tail end of the air bag, tape and fiber cloth is fixed on the ruler seat, as figure 2 As shown, the top of the airbag 103 is provided with an air nozzle 104 through which the airbag 103 is inflated and deflated, and the air nozzle 104 at the top of the airbag is arranged at the front end of the ruler tape, near the ruler hook.

[0028] Fiber cloth is also called carbon fiber cloth, carbon fiber cloth, carbon cloth, etc. The composite material made of carbon fiber has extremely high strength, and is ultra-light, resistant to high temperature and high pressure. The ruler t...

Abstract

The invention discloses an inflatable measuring ruler, and the ruler comprises a ruler body and a ruler base; the ruler body comprises two or more flexible ruler belts capable of being curled, the centers of the ruler belts are marked with division scales, the ruler belts are connected through micro-deformation fiber cloth, and an air bag is clamped between the ruler belts; the tail ends of the air bag, the ruler belt and the fiber cloth are fixed on the ruler seat. The ruler is characterized in that an air tap is arranged at the top end of the air bag, and the air bag is inflated and deflatedthrough the air tap. According to the inflatable measuring ruler, the air bag is arranged in the interlayer of the scale belt, so the inflatable measuring ruler can flexibly measure in various complex environments such as a bent and narrow environment, and the hardness of the inflatable measuring ruler can be selected by continuously adjusting the inflation pressure in the air bag so as to meet the requirements of different special measuring environments; after use, the air tap arranged at the front end of the tape body is used for deflating, the tape body is recycled and stored in the tape base, the size is small, and carrying and storage are convenient.

Description

technical field [0001] The invention relates to the technical field of geometric quantity measurement, in particular to an inflatable measuring ruler. Background technique [0002] In the technical field of geometric measurement, the current practical application is to use a tape measure for length measurement. However, the tape measure has great limitations in the measurement of some special scenes, such as narrow and irregular potholes, length measurement of narrow and long curved environments, etc. [0003] An inflatable foldable field measuring ruler (application number 91226834.4) is disclosed in the prior art, which is characterized in that the ruler body is made of rubber glue, and leather convex nails are added on the scale surface of the ruler body, and it is made of soft plastic. A variety of readable surfaces are used together. The disadvantage of this solution is that the rubber is easily deformed, and the scale on the ruler is also deformed, the measurement ac...
