Problems solved by technology

However, it is easy to have false welding or welding deviation when welding the temperature sensing sleeve, resulting in deviation of the test temperature
The different positions of the circlips will also lead to different positions of the temperature-sensing probe attached to the inner wall of the temperature-sensing sleeve, which will also cause deviations in the test temperature and reduce the accuracy of the unit’s operation.
In addition, welding consumes high energy, and the temperature-sensing sleeve is easily deformed during transportation, which affects the assembly efficiency of the temperature-sensing package
Moreover, a variety of materials need to be used in the final assembly process, and the assembly efficiency is low
[0004] Some of the existing fixing devices of the temperature-sensing package are provided with two arches, and a bayonet is provided on the opening side to form a ring-shaped fixing card. However, this assembly method requires the temperature-sensing package and the pipeline to be put together first, and then the temperature-sensing package, which increases the difficulty of operation
Moreover, the shape of the fixing card needs to be adjusted during use, which will cause imperfect fit between the fixing card and the pipeline.

Abstract

The invention belongs to the technical field of electrical equipment, and particularly relates to a fixing device which comprises a first opening sleeve provided with a first opening in the axial direction and a second opening sleeve provided with a second opening in the axial direction. The first opening faces the second opening, and a first side of the first opening is connected with a first side of the second opening. A second side of the first opening and a second side of the second opening are free sides and form a mounting opening of the fixing device. A cylinder corresponding to the first opening sleeve is externally tangent to a cylinder corresponding to the second opening sleeve. The fixing device is simple in structure, and one structure can be tightly fixed to the outer side ofthe other structure conveniently without welding. The invention further relates to heat pump equipment of which a temperature sensing probe is installed through the fixing device.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a fixing device and heat pump equipment. Background technique [0002] In the air conditioning system, when the outdoor working conditions are severe, the system pressure will be abnormally high. At this time, the exhaust temperature is much higher than that under normal outdoor working conditions, and the cylinder temperature of the compressor will also exceed the safe range, resulting in frequent start and stop of the compressor. . In order to ensure the safe operation of the air conditioning system, it is necessary to measure the temperature of the refrigerant through the temperature sensor to adjust the operating state of the air conditioner. [0003] In the prior art, the temperature-sensing probe is fixed by the copper tube of the probe. First, the copper temperature-sensitive sleeve is welded to the surface of the temperature-measuring pipe. The p...
