[0045] Figure 1 The rotating disc 2 in the structure diagram is provided with a feeding station 21 and a discharging station 23, a plurality of detection stations 22 for detecting the pressure resistance of the safety water inlet pipe 10 are arranged between the feeding station 21 and the discharging station 23, the safety water inlet pipe 10 is a safety water inlet pipe for a washing machine or a dishwasher, a water inlet connector 101 is riveted to one end of the safety water inlet pipe 10, a filter screen is arranged in the water inlet connector 101, a water outlet connector 102 is riveted to the other end of the safety water inlet pipe 10, and the water outlet of the water outlet connector 102 is bent by 90° and faces the side surface of the safety water inlet pipe 10.

[0046] As Figures 1-3 shown, the operation steps of the pressure detection mechanism for the safety inlet pipe are as follows:

[0047] S1. In the loading station 21, the water inlet of the water inlet connector 101 of the safety inlet pipe 10 is upward, and the water inlet connector 101 is placed in the first receiving groove 310 of the first hanging seat 31, the lifting plug 33 is aligned with the water inlet of the water inlet connector 101, and then the water outlet connector 102 of the safety inlet pipe 10 is placed in the second receiving groove 320 of the second hanging seat 32, the water outlet of the water outlet connector 102 is horizontally directed to the telescopic plug 34, then the lifting plug 33 is pushed down, and the telescopic plug 34 is horizontally moved, so that the lifting plug 33 is inserted into and sealed with the water inlet connector 101, and the telescopic plug 34 is inserted into and sealed with the water outlet connector 102, so that the bottom surface of the water inlet connector 101 is in contact with the groove wall of the first receiving groove 310, and the side surface of the water outlet connector 102 is in contact with the groove wall of the second receiving groove 320, then the compressed air control valve 41 is started, and compressed air is input into the safety inlet pipe 10 through the two compressed air input channels 300;

[0048] S2. The driving motor 11 driving the rotating disc 2 is started, so that the rotating disc 2 drives the tooling plate 3 to pass through the multiple detection stations 22 from the loading station 21 in sequence, and when the compressed air in the safety inlet pipe 10 reaches the set detection pressure in the detection station 22, the input of compressed air into the safety inlet pipe 10 is stopped, and the pressure is maintained for a period of time;

[0049] S3. If the pressure transmitter 42 detects that the pressure reduction value of the compressed air in the safety inlet pipe 10 during the pressure maintaining period is less than the set process threshold value, it is considered that the pressure resistance performance of the detected safety inlet pipe 10 is qualified, when the safety inlet pipe 10 follows the tooling plate 3 to reach the unloading station 23, the lifting plug 33 and the telescopic plug 3 are pushed back and reset, and the safety inlet pipe 10 is unloaded from the tooling plate 3 to the qualified product conveying line, the tooling plate 3 continues to rotate with the rotating disc 2 and reaches the loading station 21, and the steps S1 and S2 are repeated, and the pressure resistance detection of the next safety inlet pipe 10 is continued;

[0050] Conversely, if the pressure reduction of the compressed air in the safety inlet pipe 10 during the pressure holding period detected by the pressure transmitter 42 is greater than the set process threshold, the pressure resistance performance of the safety inlet pipe 10 under test is considered unqualified. When this safety inlet pipe 10 arrives at the unloading station 23 with the tooling plate 3, the lifting plug 33 and the telescopic plug 3 are pushed to retract and reset, and the safety inlet pipe 10 that has completed the test is unloaded from the tooling plate 3 into the non-conforming product collection box.

[0059] As shown in Figure 2 and Figure 3 When the safety water inlet pipe 10 follows the tooling plate 3 to reach the unloading station 23, and the telescopic plug 34 is retracted and reset, the push rod cylinder 38 is started, and the push rod 381 is pushed to move towards the second hanging seat 32, so that the push rod 381 abuts against the bottom of the water outlet connector 102, thereby making the water outlet connector 102 of the safety water inlet pipe 10 which has completed detection separate from the telescopic plug 34, so as to improve the unloading work efficiency of the safety water inlet pipe 10.

[0060] Further, it also includes an air compressor 5 and a compressed air tank 6;

[0068] Furthermore, it also includes a control device 7;

[0069] The control device 7 includes a chassis 70 and a touch screen 71;

[0070] The chassis 70 is mounted on the mounting bracket 1 and located beside the rotating disk 2; the touch screen 71 is mounted on top of the chassis 70; an analog controller is installed inside the chassis 70.

[0074] The foot switch 8 is installed near the side of the mounting bracket 1. The foot switch 8 is located between the unloading station 23 and the loading station 21. The foot switch 8 is connected to the analog controller signal.

[0075] like Figure 1 As shown, when it is necessary to manually remove the safety water inlet pipe 10 from the unloading station 23, or to place the safety water inlet pipe 10 at the loading station 21, the operator can control the temporary start and stop of the drive motor 11 through the foot switch 8 to improve the safety of operation.

[0076] Furthermore, it also includes a pressure gauge 12 and a pressure regulating valve 13;
