[0035] As Figures 1 to 7As shown in the figure, the present utility model provides a four-way valve pipe assembly, which includes a four-way valve 1 having a plurality of first connecting pipes 11. A first connector 111 is provided on each of the first connecting pipes 11. A plurality of second connecting pipes 2 communicating with external devices are connected to the four-way valve 1. A second connector 21 is provided on each of the second connecting pipes 2. A connecting assembly 3 capable of connecting and communicating the first connector 111 and the second connector 21 is provided between the first connector 111 and the second connector 21. A locking assembly 4 capable of locking the first connector 111 and the second connector 21 and separating them after unlocking is provided between the first connector 111 and the second connector 21. The locking assembly 4 includes a locking position 41 provided on the second connector 21. A plurality of rotatable members 42 are provided on the first connector 111. A locking portion 421 capable of being engaged with or disengaged from the locking position 41 as the rotatable member 42 rotates is provided on the rotatable member 42. The locking assembly 4 further includes a sliding seat 43 slidably connected to the first connector 111 and capable of connecting to a plurality of rotatable members 42. When the sliding seat 43 slides upward relative to the first connector 111, it can drive each rotatable member 42 to slide therewith, so that the upper wall surface of the locking portion 421 abuts against the lower wall surface of the locking position 41 and locks. A rotating seat 44 capable of moving relative to the sliding seat 43 and locking to the first connecting pipe 11 to make the locking assembly 4 in a locked state is connected to the sliding seat 43.

[0036] When the present utility model is in use, align the connecting assembly 3 with the first connector 111 of the first connecting pipe 11 and the second connector 21 of the second connecting pipe 2, then push the four-way valve 1 and the second connecting pipe 2, so that the first connector 111 and the second connector 21 are connected. Then rotate the second connecting pipe 2 so that the locking position 41 on the second connecting pipe 2 is aligned with the rotatable member 42, and rotate the rotatable member 42 so that the locking portion 421 on the rotatable member 42 is engaged into the locking position 41. Then slide the rotating seat 44 upward. When the rotating seat 44 slides upward along the first connecting pipe 11, the rotating seat 44 gradually drives the sliding seat 43 to move upward. The sliding seat 43 is driven to move upward relative to the first connector 111, so that the upper wall surface of the locking portion 421 abuts against the lower wall surface of the locking position 41 and locks. When the rotating seat 44 reaches a preset position, the rotating seat 44 is gradually locked to the first connecting pipe 11, and then the locking assembly 4 is in a locked state, quickly locking the connecting assembly 3, the second connecting pipe 2 and the four-way valve 1. Since the up-and-down connection method is adopted, and when locking, only the rotating seat 44 needs to be slid and rotated to complete the locking. The locking method is very simple, and the space required for locking is relatively small, which is convenient for the installation of the entire four-way valve pipe assembly.

[0037] In some embodiments, such as Figure 2As shown, the first connector 111 is provided with a plurality of protruding mounting portions 1111, a slide groove 1112 is formed between two adjacent mounting portions 1111, and a guide groove 1113 is provided on the mounting portion 1111, and a sliding portion 422 is provided on the rotating member 42, which extends into the guide groove 1113 and can slide in the guide groove 1113. When the rotating member 42 moves following the sliding seat 43, the sliding portion 422 on the rotating member 42 slides in the guide groove 1113, and the rotating member 42 slides upward along the mounting portion 1111, and the guide groove 1113 is used to limit the range of movement of the rotating member 42. The setting of the slide groove 1112 facilitates the sliding of the rotating member 42.

[0038] In some embodiments, Figure 6 As shown, the sliding seat 43 includes a main body 431, the main body 431 is provided with a connecting column 432 extending downward into the rotating member 42, the connecting column 432 is connected with a laterally extending extension portion 433, the rotating member 42 is provided with a movable space 423 for the extension portion 433 to move therein, and the rotating member 42 is provided with a making way groove 424 that can make way for the connecting column 432. The setting of the activity space 423 can make the rotating member 42 rotate relative to the extension part 433 to prevent the rotating member 42 from getting stuck. When the rotating seat 44 moves toward the preset position, the body 431 drives the connecting column 432 and the extension part 433 to slide. At this time, the extension part 433 gradually approaches the top surface of the activity space 423 and drives the rotating member 42 to move upward, so that the upper wall surface of the locking part 421 and the lower wall surface of the locking position 41 are pressed against each other, so that the locking part 421 locks the first connector 111 and the second connector 21, and the locking is more stable, and it is also more convenient to lock. The locking position 41 is a locking groove.

[0039] In some embodiments, Figure 5 As shown, the body 431 is provided with a protruding convex ring 4311, a sliding groove 430 capable of allowing the rotating seat 44 to move is formed between the convex ring 4311 and the body 431, and the rotating seat 44 is provided with a stopper 441 capable of abutting against the convex ring 4311 to prevent the rotating seat 44 from being separated from the sliding seat 43. The provision of the sliding groove 430 facilitates the rotating seat 43 to rotate relative to the sliding seat 42 and also facilitates the rotating seat 43 to slide up and down relative to the sliding seat 42.
