Description

Technical Field

[0001] The utility model relates to the technical field of nozzle detection, in particular to a nozzle detection mechanism. Background Art

[0002] When conducting a sealing test on a fire sprinkler, a sealing test device is required.

[0003] After searching, for example, a utility model patent with Chinese patent number CN220751486U discloses a fire sprinkler sealing detection device. By setting an inflation head, an exhaust fan, an exhaust pipe and an air outlet pipe, the inner cavity of the fire sprinkler is automatically inflated for sealing detection, so that when the fire sprinkler is performing the sealing detection, it can not only automatically clamp and fix the fire sprinkler, but also inflate the inside of the fire sprinkler, and automatically lower the fire sprinkler into the water tank. If bubbling occurs, it is unqualified, and if there is no bubbling, it is qualified, thereby improving the accuracy of the fire sprinkler sealing detection. However, when using the device, it is necessary to ensure that there is no leakage at the connection between the sprinkler and the inflation head. If there is leakage, bubbles will also occur at the connection during the test, affecting the test structure. In addition, the sizes of the pipes at the water inlet of different sprinklers are different. The slight size difference will cause the connection to be loose, thereby causing leakage. Therefore, a sprinkler detection mechanism is proposed to solve the above problems. Utility Model Content
