Rubber hose water tightness testing device

Abstract

A rubber hose water tightness testing device comprises a blocking structure, and further comprises a pressing structure, a driving structure and a detection structure, the detection structure comprises a supporting frame, a bearing, a rotating frame, a pressure sensor, a gear, a rotating shaft and a motor arranged on the rotating shaft, and the bearing is contained in the supporting frame. By arranging the rotating frame and arranging the pressure sensor in the rotating frame, the rotating frame can drive the pressure sensor to rotate when rotating, so that the rotating frame can rotate aroundthe hose by 360 degrees to detect an air leakage port of the hose, and meanwhile, under the driving action of the matched driving structure, the rotating pressure sensor moves in the axial directionto detect the air leakage port of the hose. Therefore, the hose can be comprehensively detected while rotating, the position of the air leakage opening can be accurately detected so that the air leakage opening can be conveniently cut off, the remaining hose can be continuously used, resource waste is reduced, and resources are fully utilized.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to a watertightness testing device for rubber hoses. Background technique [0002] With the development of industry, the use of rubber hoses has gradually increased, and the scale of production has gradually increased. After the rubber hose is manufactured, its watertightness needs to be tested to prevent a series of problems caused by poor watertightness in later use. The existing method for testing the watertightness of the rubber hose mainly increases the air pressure inside the hose by inflating the inside of the hose, and then blocks the two ends of the hose to observe the change of the air pressure inside the hose. Hours indicate that the watertightness of the rubber hose is not good, and when the air pressure remains unchanged, it indicates that the watertightness of the rubber hose is good. There are many deficiencies in the above detection method: firstly, it is impo...

AI Technical Summary

Problems solved by technology

There are many deficiencies in the above detection method: firstly, it is impossible to accurately detect the location of the rubber hose leaking or air leaking, resulting in the need to discard the whole hose when the watertightness of the testing hose is not good, resulting in waste; secondly, due to the diameter of the hose The difference in size makes the existing hose watertightness detection device unable to block the end openings of hoses with different calibers, and the scope of use is limited; finally, the existing hose end openings are mainly blocked by rubber blocks, etc. , but when the end opening of the rubber hose is blocked by a blockage block for a long time, a small amount of gas inside the hose will flow out from the opening of the end, which will affect the accuracy of the detection of the end of the rubber hose
