Description

Technical Field

[0001] The utility model belongs to the technical field of pressure switches, and in particular relates to a pressure switch installation component. Background Art

[0002] The pressure switch uses high-precision, high-stability pressure sensors and transmission circuits, and then uses a dedicated CPU modular signal processing technology to achieve the detection, display, alarm and control signal output of the medium pressure signal. The pressure switch can be widely used in the fields of petroleum, chemical industry, metallurgy, electricity, water supply, etc. to measure and control the gauge pressure and absolute pressure of various gases and liquids. It is an ideal intelligent measurement and control instrument for industrial sites.

[0003] The working principle of the pressure switch is relatively simple. There are different connectors on the pressure switch body. One connector is threadedly installed on the pipe where the fluid to be monitored flows. At the same time, this connector is equipped with various functional sensor probes. Another connector is connected to the communication wire on the unit to feed back the data measured by the sensor probe to the unit. When installing the pressure switch, due to the large structure of the pressure switch body, in the vertical direction, the pressure switch body will block the connector. In a dark environment, it may be difficult for the installer to align the connector with the pipe, affecting the installation efficiency.

[0004] The utility model with publication number CN 214251357 U discloses a pressure switch that is easy to install, which includes a switch body, a first joint and a second joint are formed on the switch body, the second joint includes a connecting section and a threaded section, a mounting structure is provided between the connecting section and the switch body, the mounting structure includes a clamping block, an elastic reset member and two telescopic guide slides arranged in parallel, the fixed end of the telescopic guide slide is fixedly inserted in the connecting section, the free ends of the two telescopic guide slides are both fixedly connected to the clamping block, a guiding inclined surface is formed at one end of the clamping block away from the telescopic guide slide, the elastic reset member is provided between the clamping block and the connecting section, and the two ends of the elastic reset member are respectively fixedly connected to the clamping block and the connecting section, a positioning hole is provided on the switch body, and a limiting groove is provided on the switch body at the positioning hole.

[0005] The installation method in the above utility model is relatively simple, and it can be quickly installed in a dark environment. However, precisely because the connection method in the above utility model is too simple, the connection between the switch body and the connection end is unstable, and it is easy to loosen when subjected to external force, thereby reducing the working efficiency of the switch body. In view of this, the present utility model is specially proposed. Utility Model Content
