Handheld portable non-contact section measuring device

Abstract

The invention discloses a handheld portable non-contact section measuring device which comprises a host shell, a touch display screen, a setting key, a level bubble, a power switch, a measuring switch, a USB TYPE-C interface, a host and measuring sensor interface, a rechargeable battery, a measuring sensor, a measuring sensor and host interface, an object catcher, a laser transmitting and receiving device and a host. The measuring sensor is a U-shaped opening piece, laser transmitters and laser receivers which are evenly arranged at equal intervals are arranged on the inner sides of a left vertical rod and a right vertical rod of the U-shaped opening piece to form a laser transmitter and receiver row, and the positions of the laser transmitters and the positions of the laser receivers on the left side and the right side are in one-to-one correspondence. The measuring device is small in size, light in weight, portable and applicable to regular and irregular sections. The measuring device does not generate traces and damages on the surface of a measured object due to the adoption of non-contact measurement. The measuring device is high in universality, high in measuring precision, simple and convenient to operate, economical and practical.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a hand-held portable non-contact section measuring device. Background technique [0002] In daily work, objects with regular cross-section shapes are generally measured by using tools such as rulers and calipers to contact the measured object, and draw the cross-sectional shape, calculate the circumference, and area. The measurement tools are simple, high-precision, and fast. However, it is difficult to use the above tools to measure irregularly shaped sections, with low precision and slow speed, and it is even more difficult to measure other positions of the measured object except the two ends. Moreover, some measured objects are prone to deformation after contact with the surface, resulting in inaccurate measurement data or damage to the measured object. SUMMARY OF THE INVENTION [0003] The object of the present invention is to design a hand-held portable no...
