Abstract

The invention discloses a conversion mechanism for a spring pressure gauge, and the mechanism comprises a case, a sealing part, a piston block, a spring, a limiting part, a drive rack, and a drive gear. The internal bottom of the case is provided with a lateral tubular housing in an integrated manner, and the other end of the tubular housing is provided with an opening. The sealing part, the piston block, the spring and the limiting part are sequentially installed in the tubular housing from the opening. The sealing part is fixed on the piston block, and two ends of the spring respectively abut against the piston block and the limiting part. The limiting part is fixed in the tubular housing, and a side wall of the tubular housing is provided with a strip-shaped hole which axially extends along the tubular housing. The piston block is provided with a connecting block which stretches out of the tubular housing through the strip-shaped hole. The drive rack is movably disposed in the case,and is fixedly connected with the connecting block. The drive gear is coaxially fixed on a pointer installation rotating shaft, and the teeth on the drive gear are engaged with the teeth on the driverack. The mechanism is simple and reasonable in structure, is convenient to assemble and operate, is small in size of products, and is beautiful in shape.

Description

technical field [0001] The invention relates to a conversion mechanism for a spring pressure gauge, which belongs to the field of spring pressure gauge structure design. Background technique [0002] A pressure gauge refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. The pressure gauge uses the elastic deformation of the sensitive element in the gauge, and then transmits the pressure deformation to the pointer by the conversion mechanism, causing the pointer to rotate to display the pressure. Pressure gauges are used in almost all industrial processes and scientific research fields, and can be seen everywhere in heat pipe networks, oil and gas transmission, water and gas supply systems, vehicle maintenance shops and other fields. A spring tube pressure gauge is disclosed in the patent document CN205426390U, which includes a case, the inner wall of the gauge is provided with a sealing gasket,...
