[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] As attached Figure 1 -Attached Figure 5 As shown, a snap-on self-sealing medical gas terminal comprises a mounting tube 1, a mounting seat 2 and an inhaler connecting tube 3, wherein the mounting tube 1 is passed through and mounted inside the mounting seat 2, an annular groove 4 is provided in the middle of the mounting tube 1, an annular mounting plate 5 is installed on the lower side wall of the annular groove 4, an annular airbag 6 is installed between the upper side of the annular mounting plate 5 and the side wall of the annular groove 4, vertical mounting plates 7 are respectively installed on opposite sides of the side wall of the annular groove 4, arc-shaped airbags 8 are respectively installed on the same side of two groups of the vertical mounting plates 7, and the lower side of the arc-shaped airbag 8 is connected to the annular airbag 6;

[0028] A sealing valve 14 is installed on the upper part of the inhaler connecting tube 3, and mounting tubes 9 are installed on opposite sides of the lower part of the inhaler connecting tube 3. A clamping block 11 is slidably installed inside the mounting tube 9, and a spring 12 is connected between the lower side of the clamping block 11 and the bottom of the mounting tube 9. The inner walls on opposite sides of the upper part of the mounting tube 1 are respectively provided with sliding grooves 10 for the mounting tube 9 to slide through, and the upper side wall of the annular groove 4 is provided with a clamping groove 13 for the clamping block 11 to be clamped into.

[0029] Through the above structure, the installation cylinder 9 passes through the slide groove 10 and enters the annular groove 4, and the inhaler connecting tube 3 is rotated to make the installation cylinder 9 rotate inside the annular groove 4, and the installation cylinder 9 squeezes the arc-shaped airbag 8, and squeezes the gas in the arc-shaped airbag 8 into the annular airbag 6, so that the annular airbag 6 expands upward, and the annular airbag 6 squeezes the bottom end of the inhaler connecting tube 3 to make close contact. At this time, the block 11 is squeezed into the installation cylinder 9 by the upper side wall of the annular groove 4, so that the spring 12 is compressed. When the block 11 rotates to the position of the slot 13, the block 11 is pushed into the slot 13 by the resilience of the spring 12, and the inhaler connecting tube 3 is positioned. In the case of non-manpower twisting, the inhaler connecting tube 3 cannot be rotated. When the inhaler is damaged, it can be repaired by closing the sealing valve 14 on the inhaler connecting tube 3. The specific structure is as follows:

[0030] Combined with Figure 3 and attached Figure 5 As shown, the annular airbag 6 is sealedly connected to the upper side of the annular mounting plate 5 and the side wall of the annular groove 4 respectively, the upper side of the clamping block 11 is an arc-shaped structure, and the lower edge of the clamping groove 13 is an arc-shaped structure.

[0031] Through the above structure, the annular airbag 6 is sealed and connected to the upper side of the annular mounting plate 5 and the side wall of the annular groove 4 respectively. When the annular airbag 6 is in close contact with the bottom end of the inhaler connecting tube 3, the gas transported in the mounting tube 1 will not leak to the outside of the inhaler connecting tube 3. The upper side of the block 11 and the lower edge of the groove 13 are both arc-shaped structures, so that when the inhaler connecting tube 3 is rotated, the block 11 can be easily removed from the groove 13.

[0032] Combined with Figure 1 and attached Figure 4 As shown, a threaded sleeve 15 is installed on the upper end of the inhaler connecting pipe 3, and a plurality of groups of mounting bolts 19 are installed through the edge of the mounting seat 2.

[0033] Through the above structure, the air supply pipe joint is connected through the threaded sleeve 15, and the mounting base 2 is installed on the air supply equipment through multiple sets of mounting bolts 19 to ensure that the mounting pipe 1 is stably connected to the air supply equipment.

[0034] Embodiment 2

[0035] Based on Example 1, please refer to the attached Figure 2 An air guide tube 16 is installed on one side of the annular airbag 6, and the other end of the air guide tube 16 passes through the mounting tube 1 and is installed with a cover body. An air release tube 17 is installed on the lower part of the side wall of the mounting tube 1, and a control valve 18 is installed on the air release tube 17.

[0036] Through the above structure of the second embodiment, air can be supplied and exhausted to the inside of the annular airbag 6 through the air guide tube 16, and the air guide tube 16 is sealed by the cover body. When the inhaler connecting tube 3 is disassembled, the gas between the installation tube 1 and the inhaler connecting tube 3 is discharged by opening the control valve 18, thereby preventing the inhaler connecting tube 3 from being suddenly ejected by air pressure during disassembly.
