Pressure instrument based on RFID Interne-of-Things technology

Abstract

The invention discloses a pressure instrument based on the RFID Interne-of-Things technology, which comprises a meter shell, a spring, a piston, a piston sealing ring, a rack, a strip gear, a main gear, a pin gear, a dial plate and a shell cover, and is characterized in that the meter shell is of an integrated structure with a disc-shaped outline, and a shell end pipe and a shell end table with coincident axial leads are arranged on the outer circle of the meter shell; the meter shell, the shell end pipe and the shell end table are internally provided with sliding grooves penetrating the meter shell, the shell end pipe and the shell end table, the outer circle of the meter shell is provided with shell threads, the surface of the inner space of the meter shell is provided with shell screw holes distributed in an annular array mode, an upper groove and a lower groove are milled in the meter shell, an upper groove hole is formed in the upper groove, a lower groove hole is formed in the lower groove, the space of the lower groove is communicated with the space of the sliding groove, and the dial plate is located in the watch shell. According to the pressure instrument based on the RFID Internet of Things technology, the pressure can be accurately displayed on the surface, and the pressure instrument has good structural reliability and is suitable for being widely popularized and used.

Description

technical field [0001] The invention belongs to the technical field of pressure instruments, and in particular relates to a pressure instrument based on RFID Internet of Things technology. Background technique [0002] The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected, and interacted, and its sound, Various required information such as light, heat, electricity, mechanics, chemistry, biology, and location can be connected through various possible networks to realize the ubiquitous connection between things and things, and between things and people, and realize the intelligence of things and processes Perceive, identify and manage. A pressure gauge is an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used, and it pervades almost all industrial processes and scientific research fields. It can be seen everywhere in heat ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing pressure instruments use springs to cooperate with the column and two gears to drive the pointer to move. The gear meshing is easy to be misplaced, which easily causes the problem that the pressure instrument is easy to be damaged, and the reliability of the supporting parts at both ends of the two gears is average. , the gears are also relatively easy to misalign, the problem of using two gears meshing to achieve a more detailed pressure display requires the use of larger gears, which will make the size of the dial too large
