[0023] The bracket 5 and the square rod 7 are slidably arranged, and the sound and light alarm 9 and the pressure sensor 12 are electrically connected, so that the square rod 7 can slide relative to the bracket 5 to disassemble and assemble the alarm structure, and the pressure sensor 12 can send a signal to the sound and light alarm 9 when it senses the weight change of the water collection tank 13, thereby making the sound and light alarm 9 sound an alarm to remind the staff that there is a leakage in the pipe.

[0024] The limiting mechanism 6 includes a sleeve 601, a clamping rod 602, a retaining ring 603 and a spring 604, and the sleeve 601 is fixedly installed on the lower surface of the bracket 5, and the inner wall of the sleeve 601 is movably connected with the clamping rod 602, and the retaining ring 603 is fixedly installed on the outer wall of the upper end of the clamping rod 602, so that the bracket 5 and the square rod 7 are in a relatively stable state through the limiting mechanism 6.

[0025] The clamping rod 602 and the sleeve 601 are slidably connected, and the clamping rod 602 and the square rod 7 form a sliding structure, which facilitates the clamping rod 602 to slide relative to the sleeve 601 and insert into or detach from the square rod 7.

[0026] The retaining ring 603 and the sleeve 601 are slidably arranged, and the lower surface of the retaining ring 603 is connected to the inner wall of the lower end of the sleeve 601 through the spring 604, so that the retaining ring 603 is elastically supported by the spring 604, so that the retaining ring 603 pushes the clamping rod 602 to be stably inserted into the square rod 7.

[0028] Working principle: When using the ultrapure water ultrafiltration connecting pipe, first Figure 1-3 and Figure 5 As shown, the user pulls the clamping rod 602, and then the clamping rod 602 and the retaining ring 603 slide relative to the sleeve 601 at the same time, and as the retaining ring 603 moves, the retaining ring 603 compresses the spring 604 and deforms, and then the user moves the positioning plate 8 to make the square rod 7 insert into the bracket 5, and then the user releases the clamping rod 602, at this time the spring 604 resets and pushes the retaining ring 603 to move upward, so that the clamping rod 602 is inserted into the square rod 7, and then the bracket 5 and the square rod 7 are in a relatively stable state to complete the installation of the alarm mechanism, and then the user connects the ultrapure water ultrafiltration pipe and the main pipe 1, when the device is working, the ultrapure water in the main pipe 1 is discharged from the main pipe 1 through the outlet pipe 2, and when the device leaks, as shown in FIG. Figure 1-2 and Figure 4 As shown, the leaked water flows into the water diversion trough 3 along the surface of the device, and then the water in the water diversion trough 3 flows into the water collecting trough 13 through the water diversion pipe 4. Next, the water collecting trough 13 is forced to move downward to compress the pressure sensor 12, and as the water collecting trough 13 moves, the water collecting trough 13 drives the support plate 14 to slide relative to the plate sleeve 10, and then the pressure sensor 12 senses the pressure change. At this time, the pressure sensor 12 sends a signal to the sound and light alarm 9, so that the sound and light alarm 9 alarms to remind the staff. Therefore, it is easy to make a timely alarm when the device leaks, thereby avoiding a series of accidents caused by continuous leakage of pipes, thereby improving the practicality of the device.
