Description

Technical Field

[0001] The utility model relates to the technical field of sensor installation, in particular to a quick-installation sensor for a refrigeration system. Background Art

[0002] The refrigeration system can be divided into steam refrigeration system, air refrigeration system and thermoelectric refrigeration system. The refrigeration system is composed of refrigerant and four major parts, namely compressor, condenser, expansion valve and evaporator. Pipelines are generally set in the refrigeration system, which are used to realize the transportation and circulation of gas or liquid.

[0003] Existing sensors can be clamped and fixed in the mounting hole position by a quick mounting structure. For example, Chinese patent application No. CN202020444113.1 discloses a quick mounting structure of a sensor, including a sensor housing, the top of the sensor housing is rotatably connected to a rotating rod, the top of the rotating rod is fixedly connected to a lever, the bottom end of the rotating rod is fixedly connected to a rotating disk, the bottom end of the rotating disk is provided with a spiral groove, the bottom end of the sensor housing is fixedly connected to a bottom shell, the outer surface of the bottom shell is provided with six sliding grooves at equal intervals, and the inside of the sliding groove is slidably connected to a connecting rod.

[0004] When using this quick installation structure, the lever and the installation thread need to be twisted separately so that the installation clamp and the installation thread respectively press against the inner wall and outer wall of the installation hole. Since the lever and the installation screw hole need to be twisted separately through the threaded structure, the sensor installation efficiency is poor. Utility Model Content
