AI Technical Summary
Technical Problem
The diaphragm of the existing peristaltic pump pressure sensor cannot fit perfectly, resulting in poor detection accuracy and limited detection range, and it is easily blown open under high pressure.
Method used
It adopts a split structure, with a base equipped with a liftable fixed slider and a slider lifting mechanism. The sensor assembly is driven by an eccentric wheel to dock with the mounting bracket, achieving stable docking of the diaphragm and avoiding the need to reserve installation space.
Benefits of technology
It improves the accuracy and range of pressure detection, ensuring that the diaphragm is not blown open under high pressure, and making pressure detection more stable.

Abstract
The utility model relates to the technical field of peristaltic pumps, in particular to a pressure gauge for a peristaltic pump flow control instrument, which is provided with a base, a fixed sliding block and a sliding block lifting mechanism are arranged on the upper portion of the base, the fixed sliding block can ascend and descend along the base under the action of the sliding block lifting mechanism, and an installation support is arranged between the base and the fixed sliding block. And sensor assemblies are arranged on the fixed sliding blocks on the two sides of the mounting bracket and the base, and the two sensor assemblies can be connected with the mounting bracket when the fixed sliding blocks descend. According to the utility model, the integrated structure of the conventional pressure gauge is changed into a split type, the liftable fixed sliding block is arranged on the base, and the fixed sliding block is lifted through the sliding block lifting mechanism, so that the butt joint of the mounting bracket and the sensor assembly is realized, the butt joint of the mounting bracket and the sensor assembly can be manually pressed during use, the pressure is more stable, and the measurement precision is higher; and moreover, an installation space does not need to be reserved, the diaphragms can be perfectly butted, the edges cannot be punched open, and the pressure detection range is larger.
