Title:
PRESSURE GAUGE
Document Type and Number:
WIPO Patent Application WO/2016/008278
Kind Code:
A1
Abstract:
Provided is a pressure gauge, comprising a gauge housing (1), a dial (2), a pointer (4), and a conversion structure for transforming the pressure and transmitting same to the pointer (4) to cause the pointer (4) to rotate; the conversion structure comprises a drive rod (3) capable of rotation, a drive base (5) capable of up-and-down motion, and a support spring (6); the pointer (4) is fixed to the upper end of the drive rod (3); the drive base (5) can be driven by air pressure to move upward; the drive base (5) is provided with a guide hole (51) for setting the drive rod (3); the support spring (6) is used in the drive base (5) for causing the drive base (5) to maintain a tendency of downward motion. The conversion structure of the present pressure gauge is simple and rational, and the screw thread fitting drive has good drive stability, such that the pressure gauge has good shockproof performance; there is no need for a complex lever structure or gear structure, thus the pressure gauge can be made very small; the structures of the components are simple, there are few mating relationships, and costs are significantly reduced.
