The welding points of the refrigerant shell are usually welded to the pipeline, and after welding is completed, a refrigeration cycle system will be formed.

[0003] Generally, after the welding of the refrigerant shell is completed, the welding points need to be tested for airtightness to avoid leakage at the welding points that affects the sealing and stability of the refrigeration system. A practical sealing detection device is required for the detection. The existing sealing detection device is relatively simple to use. The detection device is usually connected to the liquid inlet and outlet on the refrigeration meter shell, and then air is pressed into the refrigerant shell. The value changes on the detection device are then observed. Although this detection device can detect the sealing of the refrigerant shell welds, it is not convenient to detect which welding point is leaking.

[0024] As a technical optimization solution of the present invention, the lower surface of the moving block 1104 is fixedly connected with an insulating spring 1105, and the lower end of the insulating spring 1105 is fixedly connected to the outer surface of the rubber detection clip 6. A limiting mechanism is provided on the inner side of the insulating spring 1105. Through the insulating spring 1105, when the detection device is not in use, the moving block 1104 can be restored to its original position for the next use.

[0025] As a technical optimization solution of the present invention, the limiting mechanism includes an insulating telescopic rod 12, and the upper end of the insulating telescopic rod 12 is fixedly connected to the lower end surface of the moving block 1104, and the lower end of the insulating telescopic rod 12 is fixedly connected to a circular plate 1201, and the circular plate 1201 is located on the inner side of the through hole 603, and the side surface of the circular plate 1201 is fixedly connected to a horizontal plate 1202, and one end of the horizontal plate 1202 is fixedly connected to the inner wall of the through hole 603, which can limit the moving block 1104 and prevent the moving block 1104 from rotating during the rising process, thereby causing the conductive column 1103 and the conductive block 1102 to be unable to contact, and therefore cannot remind the staff that there is a leakage at the welding point.

[0026] As a technical optimization solution of the present invention, a strap ring 601 is symmetrically provided on the outer side of the rubber detection clip 6, and an adjustment buckle 602 is provided on the side surface of the strap ring 601, so that the strap ring 601 can be tightened through the adjustment buckle 602 to fix the rubber detection clip 6 at the position of the refrigerant shell welding point, and it is convenient to detect the welding point.

[0027] As a technical optimization solution of the present invention, the sealing assembly includes an air pipe 4, and one end of the air pipe 4 is fixedly connected to a shielding ring 401, one side surface of the shielding ring 401 is fixedly connected to a support plate 403, and one end of the support plate 403 is fixedly connected to a shielding plate 404, and an airbag 402 is fixedly connected between the shielding plate 404 and the shielding ring 401. The airbag 402 fixedly connected between the shielding ring 401 and the shielding plate 404 can seal pipes of different diameters, thereby improving the detection range of the detection device.

[0028] As a technical optimization solution of the present invention, a sealing gasket 3 is provided on the outside of the other end of the air pipe 4, and one side surface of the sealing gasket 3 is fixedly connected to the one side surface of the detection box 10.

[0030] When the present invention is in use, first extend one end of the air pipe 4 into the exhaust pipe 1302, then make one end of the exhaust pipe 1302 press against one side surface of the sealing gasket 3, then put the air outlet pipe 9 on the other side surface of the detection box 10 onto the air intake pipe 1303, then the staff clamps the rubber detection clamp 6 on the welding point of the process pipe 1301, and at the same time installs the binding ring 601 on the side surface of the rubber detection clamp 6, and then tightens the binding ring 601 by rotating the adjustment buckle 602. At this time, the rubber detection clamp 6 will be bound to the position of the welding point, and then the staff will rush air pressure into the interior of the detection box 10 through the air inlet 2. At this time, the gas will penetrate the inside of the refrigerant shell and pass through the gas. The gas in tube 4 will inflate the airbag 402, thereby blocking the liquid outlet of the refrigerant shell. At this time, a certain air pressure value will be displayed inside the detector 1. When the air pressure value decreases, it means that a certain welding point has a leak, and the leaked gas will enter the corresponding conduit 11 through the through hole 603, while pushing the moving block 1104 inside the conduit 11 to move upward. When the moving block 1104 moves upward to the top of the conduit 11, the conductive column 1103 will be plugged into the inside of the conductive block 1102, thereby energizing the warning light 8. At this time, the corresponding warning light 8 will light up, so the staff can directly find the leaking welding point, avoiding one by one inspection.
