Description

Technical Field

[0001] The utility model relates to the technical field of air duct detection equipment, in particular to an air duct interface sealing detection device. Background Art

[0002] The air duct is a piping system used for air transportation and distribution. There are two types of air ducts: composite air ducts and inorganic air ducts. They are widely used in air conditioning and ventilation equipment in various industries and buildings. After the air duct is processed, special equipment is required to inspect and test the sealing of the interface to improve the pass rate of the air duct.

[0003] After searching, the Chinese patent authorization number CN202020484676.3 discloses a duct sealing measuring device, including a water tank, the upper end of the water tank is fixedly connected to a support seat, the upper end of the support seat is fixedly connected to a support frame, the upper end of the support frame is fixedly installed with a first cylinder, the lower end of the first cylinder rod of the first cylinder is fixedly installed with a first connecting sleeve through bolts, the lower end of the first connecting sleeve is fixedly connected with a connecting seat, the surface of the connecting seat is fixedly installed with a second cylinder, and the end of the second cylinder rod of the second cylinder is fixedly installed with a second connecting sleeve through bolts.

[0004] The air duct sealing measurement device in the above patent has the following shortcomings: first, the above detection control mechanism uses multiple telescopic cylinders to drive the air duct to be placed in the water tank for sealing detection.

Secondly, although the above adjustment mechanism can be used to perform air injection detection on air duct interfaces of different lengths, when encountering different diameters of air ducts, the fixed sealing plate is difficult to adjust, which affects the detection effect.

[0005] To this end, we propose a duct interface sealing detection device to solve the above problems. Utility Model Content
