Technical Field

[0001] The utility model relates to the technical field of sealing test, in particular to a watertightness test device for a rubber hose. Background Art

[0002] The watertight side test is a method for testing the sealing performance of pipelines. The sealing performance is tested by water injection. In the prior art, airtightness can also be tested. However, when the airtightness test results are displayed intuitively, the pipeline needs to be immersed in water to observe whether there are bubbles. For example, a device for pipeline airtightness testing described in Publication No. CN219736710U includes a box, a lifting assembly, a driving assembly, and a clamping assembly. The box is filled with water and a mounting plate is provided in the box. The lifting assembly is located on the outer wall of the box and is connected to the mounting plate.

[0003] Although the above device can perform sealing tests, it requires clamping the pipe. When the clamp is clamped, a driving component is used. After clamping, the pipe is immersed in water. At this time, the pipe needs to be moved downward with another clamping component, which makes the driving process more complicated and increases the driving cost. Utility Model Content
