Temperature sensing sleeve assembly

The utility model relates to the technical field of refrigeration, in particular to a temperature sensing sleeve assembly. In the refrigeration field of air conditioners and the like, a temperature sensing bulb for sensing the temperature of a system needs to be fixed by inserting a bent insertion piece into a straight pipe to press the temperature sensing bulb, the insertion piece fixing part issmall in area and easy to loosen, and the straight pipe adopts a copper pipe, so that the cost is high. A temperature sensing sleeve assembly comprises a straight pipe and a sleeve, the sleeve is fixedly arranged on the outer circumferential face of the straight pipe, a concave fixing piece is arranged in the arc face of the straight pipe, and the fixing piece is composed of an oblique transitionsection and a fixing section parallel to the axial direction of the straight pipe. The fixed section and the transition section are symmetrical with the axis of the straight pipe and extend towards the two sides to form width
