The fixed connection in this embodiment can be a screw thread connection, welding, bonding or other connection methods. The lifting handle 13 partially extends out of the positioning slot 11. When several mounting expansion boxes 3 are in a stacked state, the lifting handle 13 extending out of the positioning slot 11 can be coordinated with the positioning frame 12 of the mounting expansion box 3 on the adjacent side, so that when the mounting expansion boxes 3 are in a stacked state, the lifting handle 13 can play the same limiting role as the limit block 10, so that the mounting expansion boxes 3 that are not installed on the oxygen and water storage devices are neatly stacked. The positioning slots 11 on both sides of the mounting expansion box 3 are provided with lifting handles 13, so that the operator can take the mounting expansion box 3 with both hands through the two lifting handles 13.

[0030] The mounting expansion box 3 can store liquid and high-pressure oxygen. The mounting expansion box 3 is located in the positioning slot 11 and has two communicating holes. When the mounting expansion box 3 is matched with the limit block 10, the two communicating holes in the positioning slot 11 are respectively arranged opposite to the gas circuit connector 6 and the water circuit connector 7. When the mounting expansion box 3 is used to store gas, the connecting quick connector 8 is threadedly connected to the communicating hole opposite to the gas circuit connector 6, and the other communicating hole of the mounting expansion box 3 opposite to the water circuit connector 7 is threadedly connected to a plug 9, which is used to block the communicating hole. Conversely, when the mounting expansion box 3 is used to store liquid, the connecting quick connector 8 is threadedly connected to the communicating hole opposite to the water circuit connector 7, and the other communicating hole of the mounting expansion box 3 opposite to the gas circuit connector 6 is threadedly connected to a plug 9.

The sealing cap 14 is a tubular structure, and its inner wall is provided with a stepped surface, and at least one sealing ring 19 is provided on the stepped surface. When the push rod 16 moves, the dial plate 15 can be driven to rotate, and the spiral dial groove 17 cooperates with the dial block 18, thereby driving the sealing cap 14 on the connecting joint to move toward the corresponding gas path joint 6 or water path quick street direction until it abuts. The gas path joint 6 and the water path joint 7 are both provided with a sealing ring 19 that can abut against the inner wall of the sealing cap 14. When the sealing cap 14 moves into place, the connecting quick joint 8 is connected to the water path joint 7 or the gas path joint 6, and the push rod 16 is slidably connected to the lifting handle 13 or the positioning frame 12. In this embodiment, the push rod 16 is slidably connected to the lifting handle 13, and a sliding groove for the sliding of the push rod 16 is provided on the lifting handle 13, and a return spring is provided in the sliding groove. When the positioning frame 12 of the mounting expansion box 3 is sleeved on the limit block 10, one end of the push rod 16 abuts against the limit block 10, and the limit block 10 pushes the push rod 16 to move while entering the positioning frame 12. When the limit block 10 completely enters the positioning frame 12, the sealing cap 14 completes the sealing connection of the water connector 7 or the air connector 6. When the mounting expansion box 3 is driven to disengage from the positioning block, the push rod 16 is reset under the action of the spring, and synchronously drives the toggle plate 15 and the sealing cap 14 to reset.

The lock groove includes an arc-shaped guide section 21 and a linear limit section 22. When the limit block 10 completely enters the positioning frame 12, the lock column enters the limit section 22 from the guide section 21, which can limit the limit block 10 to move in the opposite direction of entry relative to the positioning frame 12, thereby preventing the positioning frame 12 from disengaging from the limit block 10. The lock column can only be driven to disengage from the lock groove by rotating the toggle block. An avoidance hole 23 is provided on the limit block 10 relative to the push rod 16, and a push piece is slidingly provided on the limit block 10. The push piece is used to cover the avoidance hole 23. When the positioning frame 1 When 2 is set on the limit block 10, the push rod 16 abuts against the abutment, and a toggle rod is provided on the lifting handle 13. The toggle rod is a 90-degree bent part, and the bending part of the toggle rod is pivotally connected to the lifting handle 13. When the limit block 10 completely enters the positioning frame 12, the lifting handle 13 abuts against the limit block 10, and one end of the toggle rod abuts against the abutment. Pressing the other end of the toggle rod can drive the toggle rod to push the abutment to move, so that the abutment exposes the avoidance hole 23. The push rod 16 enters the avoidance hole 23 under the action of its matching spring, and at the same time drives the toggle disk 15 to reset, thereby realizing the separation of the mounting expansion box 3 from the limit block 10. The limit block 10 is provided with a reset spring for resetting the abutment. When the mounting expansion box 3 is separated from the limit block 10, the abutment covers the avoidance hole 23 again.

[0033] See also Figure 4 The lifting handle 13 is in an inverted U-shape, and both sides of the U-shape are fixedly connected to the inner side walls of the positioning frame 12. The bottom surface of the U-shape is a gripping section. The avoidance groove 20, the avoidance hole 23 and the block 23 provided on the limit block 10 are also provided on the gripping section of the lifting handle 13. The connecting quick connector 8 is an electrically controlled three-way valve, and the two ends of the connecting quick connector 8 are respectively connected to the mounting expansion box 3 and the water connector 7 or the gas connector 6. The remaining end of the connecting quick connector 8 is connected to the auxiliary quick connector 25 through a pipeline. The auxiliary quick connector 25 is arranged on the gripping section of the lifting handle 13. When the mounting expansion box 3 is in a stacked state, the lifting handle 13 of the mounting expansion box 3 enters the positioning frame 12 of the adjacent mounting expansion box 3 on one side, and at the same time pushes the push rod 16 of the adjacent mounting expansion box 3 to move, and the dial 15 is locked relative to the avoidance groove 20. At the same time, the mounting expansion boxes 3 are connected in sequence through the auxiliary quick connector through the tee, so that the auxiliary quick connector in the stacked state can form a liquid or gas to be replenished at the same time.
