Mobile phone infrared data transmission volume correction instrument convenient to disassemble and assemble

Abstract

The invention discloses a mobile phone infrared data transmission volume correction instrument convenient to disassemble and assemble. The volume correction instrument comprises a volume correction instrument front shell, wherein a volume correction instrument rear shell is fixedly arranged on the back surface of the volume correction instrument front shell through a fastening bolt; an inserting and fixing assembly is fixedly arranged on the volume correction instrument rear shell; a clamping assembly is inserted into the inserting and fixing assembly; a mobile phone infrared data transmissionmodule board is clamped on the clamping assembly. When the mobile phone infrared data transmission module board is installed, firstly the jacking elastic plate on one side of the clamping assembly isoutwards separated; therefore, the plate bodies at the two ends of the mobile phone infrared data transmission module board can be conveniently clamped into the two U-shaped clamping plates; an inserting and fixing ball head on the clamping assembly is inserted and fixed into an embracing ball groove in the inserting and fixing assembly, the three arc-shaped embracing pieces are connected with the inserting and fixing ball head in an embracing and fastening mode, and through the one-clamping-one-inserting mode, mounting, using, dismounting, overhauling and replacing operation between the mobile phone infrared data transmission module board and the volume correction instrument can be achieved.

Description

technical field [0001] The invention belongs to the technical field of flowmeters, and in particular relates to a mobile phone infrared data transmission volume corrector which is easy to assemble and disassemble. Background technique [0002] Infrared communication is a kind of wireless communication technology using infrared as the medium. Infrared is an electromagnetic wave. As an information carrier, the infrared light band used to realize data transmission belongs to near-infrared, with a wavelength of 0.75μm-25μm, and the wavelength is relatively short. The diffraction ability of obstacles is poor, so infrared communication is most suitable for short-distance communication occasions. Because infrared communication does not require physical connection, the operation is simple and the cost of implementation is low, and it has strong anti-interference ability, high reliability of transmission information, and functional Due to the advantages of low power consumption, it i...

Problems solved by technology

[0003] The existing technology has the following problems: In recent years, infrared communication technology has been developed rapidly, especially in the fields of instrumentation and electronics, but most of today's volume correctors do not have the function of infrared transmission data, and cannot Carry out infrared communication with mobile phones to realize data reading and parameter setting. At the same time, due to the high precision and integration of the existing mobile phone infrared data transmission module boards, there is a lack of a volume corrector for easy disassembly and assembly of mobile phone infrared data transmission module boards, which is not conducive to Assembly and disassembly, maintenance and replacement of equipment during use
