[0022] The locking piece includes two pull blocks 4 which are radially movably connected to the outside of the fixing ring 2. Two radially symmetrical arc grooves 5 are axially opened on the opposite surfaces of the fixing ring 2 and the retaining ring 7. An arc block 12 is axially movably inserted in each arc groove 5. A through hole 13 is vertically passed through the outside of the arc block 12. A plug-in block 14 is axially movably inserted in the through hole 13. The plug-in block 14 is movably connected in the arc groove 5 and is connected to the pull block 4. A countersunk hole 10 is radially passed through the arc groove 5. A pull rod 9 is axially slidably passed through the countersunk hole 10. One end of the pull rod 9 is fixedly connected to the pull block 4, and the other end is fixedly connected to the plug-in block 14. The outer edge of the pull rod 9 is sleeved with a first spring 11. The first spring 11 is displaced between the plug-in block 14 and the large diameter end of the countersunk hole 10. The tee 1 and the fixing ring 2 are both made of brass.

[0023] By connecting the tee piece 1 to the water pipe 8 through a locking piece consisting of a pull block 4, a first spring 11, a pull rod 9, an arc block 12 and an insert block 14, there is no need to rotate the thread multiple times for disassembly and assembly when the water pipe 8 and the tee piece 1 are disassembled, thereby improving the convenience and efficiency of disassembly and assembly of the water pipe 8 and the tee piece 1.

[0024] Reference Figure 2 and Figure 4 In order to improve the sealing performance of the connection between the water pipe 8 and the tee 1, the sealing member includes a support ring 18 axially slidably connected to the outer edge of the water pipe 8, two radially symmetrical slide grooves 15 are axially opened on the outside of the water pipe 8, and a slider 16 is slidably connected in each slide groove 15. Both sliders 16 are fixedly connected to the inner side of the support ring 18, and a compressed second spring 17 is fixed between the slide groove 15 and the slider 16. A second rubber ring 19 is concentrically fixed on one side of the support ring 18 close to the tee 1. A stepped groove 3 is provided inside each end of the tee 1, and a first rubber ring 6 is concentrically fixed in the stepped groove 3, and the first rubber ring 6 abuts against the second rubber ring 19.

[0026] Working principle: When connecting the water pipe 8 with the tee 1, first pull the two pull blocks 4 outward so that the plug block 14 is retracted into the countersunk hole 10, and the first spring 11 is compressed. Then the water pipe 8 is docked with the tee 1. When docking, the second rubber ring 19 is abutted with the first rubber ring 6, and the arc block 12 is inserted into the arc groove 5, so that the retaining ring 7 abuts against the outer opening of the tee 1. At the same time, the second spring 17 is compressed, and then the two pull blocks 4 are released, and the first spring 11 in the compressed state is reset. When the first spring 11 is reset, it pushes the plug block 14 from the countersunk hole 10 to the through hole 13 on the plug block 14, thereby completing the connection between the water pipe 8 and the tee 1.
