The invention relates to the technical field of elastic elements, and discloses an elastic element with good anti-seismic property for a pressure instrument. The elastic element comprises a base, wherein the upper end of the base is connected with a fork spring, the fork spring comprises two symmetrically arranged piston tubes, and the center of the upper end of the fork spring is connected with the two piston tubes through an anti-seismic mechanism; the anti-seismic mechanism comprises a piston tank, the piston tank is fixedly connected to the center of the upper end of the fork spring, a piston is slidably connected to the inner tank wall of the piston tank, a transmission column is fixedly connected to the center of the upper end of the piston, a matched transmission hole is formed in the position, which corresponds to the transmission column, of the center of the tank top of the piston tank, the end, which is away from the piston, of the transmission column penetrates through the transmission hole and is fixedly connected with a transmission plate, and the two ends of the transmission plate are connected with the outer tube walls of the opposite sides of the two piston tubes. According to the elastic element with the good anti-seismic property for the pressure instrument, the problem that the anti-seismic property of the pressure instrument is reduced due to the fact that an existing elastic element of a shock type pressure instrument only adopts a fork spring structure and is poor in anti-seismic effect can be solved.
Description
technical field [0001] The invention relates to the technical field of elastic elements, in particular to an elastic element for pressure instruments with good shock resistance. Background technique [0002] The shockproof pressure gauge whose elastic element is a spring tube is a kind of instrument widely used in industrial production. The pressure of a liquid, gas or vapor. The instrument has stable indication and clear reading, and is widely used in heavy machinery, mining, petroleum, chemical industry, metallurgy, electric power and other departments. The elastic element (spring tube) of this kind of instrument is in direct contact with the medium, so it can only be used to measure the pressure of non-crystallized and non-solidified liquid and gas, and cannot measure the pressure of mud, cement, etc. that are easy to solidify, easy to crystallize, and high-viscosity. . [0003] The retrieved publication (announcement) number CN104316254A discloses an elastic element o...
