Summary of the invention
The present invention is directed in the prior art metering meter counter can not seal fully, it is impaired to cause electron device to make moist easily, thereby make the lost of life of product, the deficiency that stability is bad, a kind of complete sealed-off counter is provided, has guaranteed that effectively the measuring instrument counter is not subjected to the hermetically sealed counter of magnetic coupling transmission of external environmental interference.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
The hermetically sealed counter of magnetic coupling transmission, comprise gauge outfit, gauge outfit base plate and exocoel axle plate washer, gauge outfit is provided with counting exocoel and counting inner chamber, counting exocoel and counting inner bore cavity are isolated fully, and the counting exocoel comprises the exocoel axle, and the exocoel axle is provided with outer magnetic coupling wheel, outer magnetic coupling wheel inside is embedded with outer magnetic coupling magnet steel, the counting inner chamber body comprises lumen shaft, and lumen shaft is provided with character wheel and interior magnetic coupling wheel, magnetic coupling magnet steel in interior magnetic coupling wheel inside is embedded with.Substitute the pattern that the tradition axle rotates with the magnetic coupling transmission, exocoel is caused by axis hole in the counter leakage, gas leakage, drainage have thoroughly been solved, thereby guaranteed the good environment for use of electronic product in the counter, improve the serviceable life of reliability, stability and the measuring instrument of measuring instrument, also possessed characteristics such as technology is accurate, transmission is sensitive, assembling is easy, highly versatile simultaneously.
As preferably, to count inner chamber body and also comprise seal pad, the seal pad symmetria bilateralis is provided with vertical plate, and vertical plate promptly has supporting role to bearing, will count bore seal again, guarantees the leakproofness of technology inner chamber.
As preferably, the profile of outer magnetic coupling magnet steel and interior magnetic coupling magnet steel is loop configuration, and outer magnetic coupling magnet steel and interior magnetic coupling magnet steel embeds outer magnetic coupling wheel respectively and interior magnetic coupling is taken turns.Outer magnetic coupling magnet steel is that ring-type embeds the end of outer magnetic coupling wheel near the counting inner chamber, and the magnetic coupling wheel was near an end of counting exocoel in interior magnetic coupling magnet steel correspondence embedded.
The gauging table that has the hermetically sealed counter of magnetic coupling transmission, comprise housing, placard comprises the hermetically sealed counter of magnetic coupling transmission, comprise gauge outfit, gauge outfit base plate and exocoel axle plate washer, gauge outfit is provided with counting inner chamber and counting exocoel, two cavitys are isolated fully, the counting outer chamber comprises the exocoel axle, the exocoel axle is provided with outer magnetic coupling wheel, outer magnetic coupling wheel inside is embedded with outer magnetic coupling magnet steel, the counting inner chamber body comprises lumen shaft, and lumen shaft is provided with character wheel and interior magnetic coupling wheel, magnetic coupling magnet steel in interior magnetic coupling wheel inside is embedded with.
According to technical scheme of the present invention, substitute the pattern that the tradition axle rotates with the magnetic coupling transmission, exocoel is caused by axis hole in the counter leakage, gas leakage, drainage have thoroughly been solved, thereby guaranteed the good environment for use of electronic product in the counter, improve the serviceable life of reliability, stability and the measuring instrument of measuring instrument, also possessed characteristics such as technology is accurate, transmission is sensitive, assembling is easy, highly versatile simultaneously.
