Abstract

The invention relates to a pressure control structure in the field of pressure detection, control and overload protecting device, which is designed aiming at the unreasonable structure of a known like product. The invention adopts the technical key that: the pressure control structure consists of a structural base body, a sliding contact combined body, a pressure adjusting contact combined body, and a matched pressure control circuit interface unit. The invention has four technical proposals which can well solve the technical problems of simplex function, unstable working condition, complexity increment, and reduced service life of the device difficult to be solved in the prior like products. The pressure control structure has the advantages of good versatility, wide application range, simple and reasonable structure, and convenient installation and usage.

Description

technical field [0001] The invention relates to a control device used for pressure detection, control and overload protection. Background technique [0002] At present, the existing main forms of devices used for pressure detection, control and overload protection and similar purposes are: mechanical, piezoelectric, resistive, capacitive, magnetoelectric, etc. These structures have the following disadvantages: [0003] (1) Single function. [0004] (2) The applicable conditions are relatively harsh, and the anti-interference performance is poor; the working state is unstable, and it is easy to produce shock or jitter. [0005] (3) Since the multi-function detection and logic control cannot be realized in the same simple mechanical structure, the complexity of the control circuit or equipment is increased, and the reliability of the equipment performance is reduced. [0006] (4) The device often puts the equipment in an extremely unreasonable state of use, reducing the ser...
