Then, air is blown into the concentration frame 12 through the air inlet pipe 15, then the air enters the hose 5 through the first through hole 111 so as to increase the air pressure in the hose 5, the hose 5 is in a stretched state, the piston 13 also moves towards the direction away from the blocking block 11 until the air pressure in the hose 5 is proper, and then the valve 16 is closed so as to prevent the air pressure in the concentration frame 12 from being sprayed out from the air inlet pipe 15, and at the moment, the piston 13 moves for a distance towards the direction away from the blocking block 11. Then click 48 drives the rotating shaft 47 to rotate, so that the gear 46 rotates, the gear 46 drives the rotating frame 43 to rotate, so that the pressure sensor 44 rotates around the hose 5 and can rotate 360 degrees, so as to detect whether an air leakage opening exists in the section of the hose 5, when air is sprayed onto the pressure sensor 44 through the air leakage opening, the air pressure detected by the pressure sensor 44 at the moment is increased, and therefore the air leakage opening exists in the section of the hose can be judged. The push rod 32 and the third connecting rod 33 can be driven by the cylinder 31 to enable the detection structure 4 to move axially, so that the rotating frame 43 and the pressure sensor 44 can rotate around the hose 5, and the pressure sensor 44 rotating around the hose can also move axially so as to perform comprehensive detection processing on the hose 5, when a gas leakage opening is detected, manual marking can be performed, an area with the gas leakage opening can be conveniently cut off at the later stage, the rest hose 5 can be continuously used, and when the central axis of the rotating frame 43 is collinear with the central axis of the hose 5, the distance from the pressure sensor 44 to the outer circumferential surface of the hose 5 in the rotating process is inconvenient, so that the gas pressure sprayed out from the gas leakage opening can be effectively detected, and the detection accuracy is ensured; then, the data detected by the pressure sensor 44 is wirelessly transmitted to a second wireless transceiver module of the terminal through the first wireless transceiver module 45, then the second wireless transceiver module transmits the data received by the second wireless transceiver module to the processor for processing, and transmits the processed data to the memory for storage, and the processor can transmit an instruction to the display and the memory, so that the data stored in the memory is transmitted to the display for display, and a user can conveniently obtain related data in real time. When detecting for a long time and the gas in the hose 5 leaks gas through the gas leakage port or the end part thereof, the piston 13 can move towards the direction of the blocking block 11 under the thrust action of the compressed first spring 14, so as to keep the gas pressure in the concentration frame 12 and the hose 5 appropriate, and the detection structure is more accurate and accurate, can be durable, and is low in cost and suitable for popularization and application.

The rotation angular velocity and the axial movement velocity of the rotating frame 43 are described below with specific parameters:

when the length of the hose to be detected is 1 meter, the time length of the rotating frame 43 moving from one end of the hose 5 to the other end along the axial direction is 8 minutes, and the axial moving speed is 0.21 cm/s; while the rotating frame 43 can rotate 360 degrees in 2 seconds so that its angular velocity is 180 degrees/s. Therefore, the rotation angular speed of the rotating frame 43 is 180 degrees/s through the motor 48 and the air cylinder 31, the detection of the hose can be completed when the axial moving speed is 0.21cm/s, and when an air leakage point is detected, relevant pressure parameters can be displayed in the display, at the moment, the hose can be marked manually, the hose is convenient to cut off in the later period, and the rest part of the hose can be used continuously.

So far, the use process of the rubber hose water tightness testing device is described.
