[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1 As shown, a flame-retardant PE water supply pipe includes a pipe body 1. Fireproof plates 2 are provided on both the left and right sides of the pipe body 1. A mating groove 21 is provided at the right end of the left fireproof plate 2, and a mating block 22 is fixedly connected to the left end of the right fireproof plate 2. The surface of the mating block 22 is slidably connected to the interior of the mating groove 21. Fastening rings 3 are provided at both the front and rear ends of the fireproof plate 2. Grooves 31 are provided on the sides of the two fastening rings 3 that are close to each other. The front and rear ends of the fireproof plate 2 are slidably connected to the interiors of the two grooves 31 respectively. Flanges 4 are fixedly connected to the ends of the two fastening rings 3 that are far apart from each other. Connecting components 5 are provided on both the upper and lower sides of the fastening rings 3. Positioning elements 6 are provided on both the left and right sides of the fastening rings 3. Several support columns are fixedly connected to the inner walls of both fireproof plates 2. 7. The other ends of several support columns 7 are slidably connected to the surface of the pipe body 1. In use, two fireproof plates 2 are placed on both sides of the pipe body 1, and fastening rings 3 are connected to both ends of the fireproof plates 2. The fastening rings 3 are fixed to the fireproof plates 2 by fixing bolts 8. Then, through the cooperation of the locking block 54 and the locking groove 55 in the connecting assembly 5, the fastening rings 3 are tightly connected, which drives the fireproof plates 2 to cover and seal the pipe body 1. The anti-slip pads 62 in the positioning component 6 abut against the pipe body 1 to increase friction and prevent the fireproof plates 2 from sliding along the pipe body 1. In the event of a fire, the fireproof plates 2 are used as a physical barrier, and the support columns 7 form a heat insulation air layer between the fireproof plates 2 and the pipe body 1, which delays or even prevents the PE pipe from being ignited. The flame retardant effect is good and the safety hazards are effectively reduced.

[0023] Furthermore, such as Figure 2 - Figure 5As shown, the upper connecting assembly 5 includes a first mounting bracket 51 and a second mounting bracket 52. The first mounting bracket 51 is fixedly connected to the top of the right-side fastening collar 3, and the second mounting bracket 52 is fixedly connected to the top of the left-side fastening collar 3. A pressure plate 53 is slidably installed inside the first mounting bracket 51, and the left end of the pressure plate 53 extends into the interior of the second mounting bracket 52. A locking block 54 is fixedly connected to the top of the pressure plate 53, and a locking groove 55 is opened on the top of the second mounting bracket 52. The surface of the locking block 54 engages with the interior of the locking groove 55. A pressure block 56 is fixedly connected to the top of the right end of the pressure plate 53, and a pair of damping springs 57 are fixedly connected to the bottom of the right end of the pressure plate 53. The other ends of the two damping springs 57 are fixedly connected to the inner wall of the first mounting bracket 51. Several fixing bolts 8 are provided on the surface of the fastening collar 3. When installing the fireproof plate 2, the groove 31 is used to secure the bolts. The fastening collar 3 is connected to the front and rear ends of the fireproof board 2, and the fastening collar 3 is fixed to the two ends of the fireproof board 2 using the fixing bolt 8. Then, the two fireproof boards 2 are spliced ​​together by the mating groove 21 and the mating block 22. At this time, the end of the pressure plate 53 in the first mounting bracket 51 extends into the second mounting bracket 52. Through the cooperation of the locking block 54 and the locking groove 55, the first mounting bracket 51 and the second mounting bracket 52 respectively drive the two fastening collars 3 to fit tightly together. Then, the fastening collar 3 drives the fireproof board 2 to be tightly connected, avoiding the gap between the two fireproof boards 2. The fireproof board 2 blocks the flame and prevents the pipe body 1 from being directly ignited. The support column 7 makes a gap between the fireproof board 2 and the pipe body 1, which acts as a heat insulation air layer to further reduce heat transfer, delay or even prevent the PE pipe from being ignited, and improve the flame retardant performance of the PE pipe.

[0024] The right-side positioning component 6 includes a drive screw 61 and a pair of limiting grooves 66. The drive screw 61 is threadedly connected to the right end of the right-side fastening collar 3. An anti-slip pad 62 is rotatably mounted on the left end of the drive screw 61, and the left end of the anti-slip pad 62 abuts against the right end surface of the tube body 1. A telescopic sleeve 63 is fixedly connected to the right end of the drive screw 61, and a rotating plate 64 is fixedly connected to the other end of the telescopic sleeve 63. Limiting rods 65 are fixedly connected to both the upper and lower sides of the left end of the rotating plate 64. Both limiting grooves 66 are opened at the right end of the right-side fastening collar 3, and the left ends of the two limiting rods 65 are slidably connected to the inside of the two limiting grooves 66 respectively. The movable plate 64 drives the telescopic sleeve rod 63 to rotate, which in turn drives the drive screw 61 to rotate, causing the drive screw 61 to extend inward and press the anti-slip pad 62 against the surface of the tube body 1, increasing friction and preventing the fireproof plate 2 from sliding along the tube body 1. After reaching a suitable clamping force, the limiting rod 65 is aligned with the limiting groove 66, and the rotating plate 64 is released. The return spring inside the telescopic sleeve rod 63 causes the telescopic sleeve rod 63 to retract, thereby causing the rotating plate 64 to drive the end of the limiting rod 65 to insert into the limiting groove 66, locking the drive screw 61, maintaining the clamping force, preventing rotation and loosening, and improving the practicality of the device.

[0025] The working principle of this utility model is as follows: In use, the fastening collar 3 is fixed to both ends of the fireproof plate 2 by the fixing bolt 8. The two parts of the fireproof plate 2 are connected by the docking groove 21 and the docking block 22. By using the cooperation of the locking block 54 and the locking groove 55, the fastening collar 3 at both ends of the fireproof plate 2 is tightly fitted together, thereby driving the fireproof plate 2 to be tightly connected and avoiding gaps. By rotating the rotating plate 64, the anti-slip pad 62 is pressed against the surface of the pipe body 1 by the driving screw 61, increasing friction and preventing slippage. In the event of a fire, the fireproof plate 2 is used to block the flames and prevent the pipe body 1 from being directly ignited. The support column 7 forms a heat insulation air layer between the fireproof plate 2 and the pipe body 1, reducing heat transfer, delaying or even preventing the PE pipe from being ignited, with good flame retardant effect and reducing safety hazards.
