[0028] See also Figures 1 to 5As shown, the present embodiment provides an installation structure of an air connecting head 2 of a portable automatic pressurizing system, which includes a shell 1, an air connecting head 2 and a connecting member 3. The shell 1 includes a first fixing member 11 and a second fixing member 12. The first fixing member 11 is arranged at the top end of the shell 1. A receiving groove 13 is arranged in the middle position of the first fixing member 11. The second fixing member 12 is symmetrically arranged on both sides of the first fixing member 11. A mounting hole 14 is opened on the second fixing member 12. At least a portion of the air connecting head 2 is clamped in the receiving groove 13. The connecting member 3 includes a docking plate 31 and a limiting hole 32. The limiting hole 32 is opened on the first surface of the docking plate 31 corresponding to the second fixing member 12. A clamping groove 33 is arranged on the second surface of the docking plate 31. The clamping groove 33 is configured to clamp at least a portion of the air connecting head 2.

[0029] Specifically, the butt joint plate 31 is an L-shaped plate, and the second surface of the butt joint plate 31 is horizontally arranged.

[0030] It can be seen that the first fixing member 11 is used to limit the air head 2 once to prevent it from rotating, the setting of the docking plate 31 is used to limit and fix the air head 2 twice, the slot 33 is used to limit and fix the air head 2 three times, and the connection of the air head 2 is reinforced by the second fixing member 12 and the limiting hole 32, which has the advantage of improving the connection stability of the air head 2.

[0031] As an embodiment, the air connecting head 2 includes a limit member 21 and an air pipe 22. The shape of the limit member 21 is set corresponding to the shape of the accommodating groove 13. The air pipe 22 is passed through the middle position of the limit member 21. The first end of the air pipe 22 passes through the top of the shell 1, and a part of the second end of the air pipe 22 is clamped in the clamping groove 33.

[0032] It can be seen that by setting the shapes of the limiting member 21 and the accommodating groove 13 correspondingly, the limiting member 21 can be limited in at least two directions by the accommodating groove 13, preventing the air connector 2 from rotating during connection and affecting the connection efficiency, which has the advantage of increasing the connection stability.

[0033] As an implementation manner, a connection hole is further provided on the limiting member 21, and at least a portion of the first end of the air pipe 22 is provided in the connection hole.

[0034] Specifically, the connection hole is arranged at the middle position of the limiting member 21, a part of the air pipe 22 is arranged in the connection hole, and the first end and the second end of the air pipe 22 respectively pass through the connection hole.

[0035] It can be seen that the setting of the limiting member 21 is used to increase the stability of the air pipe 22, thereby increasing the connection stability of the connection end of the air pipe 22.

[0036] As an embodiment, the first fixing member 11 includes a first fixing plate 111, a second fixing plate 112 and a connecting plate 113. The first fixing plate 111 is horizontally arranged at the top of the shell 1, the second fixing plate 112 is arranged below the first fixing plate 111 and parallel to the first fixing plate 111, the first end of the connecting plate 113 is connected to the first fixing plate 111, and the second end of the connecting plate 113 is connected to the second fixing plate 112.

[0037] Specifically, the second surface of the docking plate 31 is located below the second fixing plate 112 to support the limiting member 21 , thereby increasing the stability of the connection of the gas connection head 2 .

[0038] It can be seen that by dividing the first fixing member 11 into two layers, the limiting force of the limiting member 21 is increased, which has the advantage of increasing the connection stability of the air connection head 2.

[0039] As an embodiment, the second fixing member 12 is cylindrical, the first end of the second fixing member 12 is fixed to one side of the first fixing member 11, the mounting hole 14 is opened at the second end of the second fixing member 12 along the length direction of the second fixing member 12, and the two second fixing members 12 are symmetrically arranged on both sides of the first fixing member 11.

[0040] It can be seen that the setting of the limiting hole 32 facilitates the second fixing member 12 to determine the installation position, and facilitates the fastener to pass through the limiting hole 32 and enter the installation hole 14, thereby improving the installation efficiency of the second fixing member 12.

[0041] Specifically, the limiting hole 32 can also be provided with a limiting mounting block corresponding to the second fixing member 12, and a snap-in hole is provided in the middle of the limiting mounting block. By snapping at least a portion of the second fixing member 12 into the snap-in hole, the second fixing member 12 is connected and fixed to the limiting hole 32.

[0042] As an embodiment, the docking plate 31 further includes a limiting protrusion 34 , which is disposed at a middle position between the two limiting holes 32 and above the second surface, and a contact surface of the limiting protrusion 34 is provided with a curved surface.

[0043] It can be seen that, by providing the limiting protrusion 34 , the limiting effect of the docking plate 31 on the trachea 22 is increased, and the stability of the installation of the trachea 22 is increased.

[0044] As an implementation manner, the second fixing member 12 and the limiting hole 32 are connected by a fastener.

[0045] Specifically, the interior of the mounting hole 14 is provided with threads.

[0046] It can be seen that the second fixing member 12 is docked with the limiting hole 32 and is fixed by the fastener penetrating the limiting hole 32 and the mounting hole 14 .

[0047] The specific working principle of the gas connection head 2 installation structure of the above-mentioned portable automatic pressurization system is as follows:

[0048] The limiting member 21 with the air pipe 22 installed is inserted into the accommodating groove 13, the limiting hole 32 is connected to the second fixing member 12, and the installation is completed by threading through the fastener.
