[0040] Specifically, the reinforcement plate 4 at the right end of the rear side of the shell 1 has two sliding grooves 6 equidistantly provided on the rear side of the reinforcement plate 4, and a sliding block 7 is slidably connected in the sliding groove 6. The rear sides of the two sliding blocks 7 are jointly fixedly connected to the movable splint 8, and the left end of the rear side of the reinforcement plate 4 is fixedly connected to the fixed splint 5. The adjacent side of the fixed splint 5 and the movable splint 8 is used to place the gas tank 9. The gas tank 9 can be easily installed and fixed by moving the movable splint 8. The compressed gas first reaches the gas tank 9 through the gas pipe 10.

When the gas pressure in the gas tank 9 reaches a certain level, the gas continues to be transmitted in the gas pipe 10 under pressure through the inflation port 12 to inflate the aircraft tire.

[0041] Reference Figure 1 、 Figure 4 and Figure 5 The wheel block mechanism 2 includes a rotating groove 201, which is opened on the right side of the bottom plate 16. It provides a rotatable space for the rotating block 202, so that the rotating block 202 can rotate flexibly inside it; the rotating groove 201 is internally rotatably connected to the rotating block 202, and the rotating block 202 can rotate in the rotating groove 201, thereby changing the angle of the component connected thereto; the top of the rotating block 202 is fixedly connected to a horizontal plate 203, and the horizontal plate 203 changes direction as the rotating block 202 rotates, and its position can be adjusted to adapt to different usage conditions; the top of the horizontal plate 203 is provided with a moving groove 204, and the moving groove 204 provides a path and space for the sliding of the moving block 206, so that the moving block 206 can move therein; moving A plurality of limiting holes 205 are equidistantly provided on the left side of the groove 204. The limiting holes 205 can cooperate with limiting bolts 207 to limit the position of the moving block 206 and achieve precise fixation. Both ends of the interior of the moving groove 204 are slidably connected to moving blocks 206. The moving blocks 206 can slide in the moving groove 204 to adjust the position of the wheel blocking plate 208. The left sides of the two moving blocks 206 are rotatably connected to the limiting bolts 207. The limiting bolts 207 can be inserted into the limiting holes 205 to fix the position of the moving blocks 206 and prevent the moving blocks 206 from sliding at will. The tops of the two moving blocks 206 are fixedly connected to the wheel blocking plates 208. The wheel blocking plates 208 are used to directly block the aircraft tires to prevent the tires from rolling during the inflation process.

[0042] Specifically, when it is necessary to perform a blocking operation on the aircraft tire, the horizontal plate 203 can be rotated to a suitable angle first so that it is roughly aligned with the direction of the tire, and then the movable block 206 can be slid to adjust the distance between the two wheel blocking plates 208 to adapt to the sizes of different tires. After the adjustment is in place, the movable block 206 is fixed by the cooperation of the limiting bolt 207 and the limiting hole 205, so that the wheel blocking plate 208 remains stable, thereby effectively blocking the aircraft tire and preventing the tire from accidentally rolling during operations such as inflation.

[0043] Reference Figure 1 and Figure 2 The front side of the shell 1 is fixedly connected with a pressure monitor 14, which is used to sense the pressure inside the inflatable device in real time and collect and monitor the pressure data. The left side of the shell 1 is fixedly connected with a pressure gauge 15, which can intuitively display the pressure value, so that the staff can clearly understand the current pressure information and provide a reference for operation. The pressure monitor 14 is electrically connected to the pressure gauge 15. This connection method can accurately transmit the data obtained by the pressure monitor 14 to the pressure gauge 15, so that the displayed pressure data is consistent with the actual monitoring situation. The left side of the shell 1 is fixedly connected with a switch 13, the switch 13 is used to control the on / off of the circuit and is an operating component for starting or stopping the compressor 3. The switch 13 is electrically connected to the compressor 3. The switch 13 can conveniently power on or off the compressor 3, thereby controlling the operation and stopping of the compressor 3. The four corners of the bottom of the bottom plate 16 are fixedly connected to a rotating frame 24. The rotating frame 24 provides a stable installation position and rotation support for the rotating wheel 17, ensuring that the rotating wheel 17 can rotate normally. The bottoms of multiple rotating frames 24 are rotatably connected to the rotating wheel 17, and the rotating wheel 17 can roll on the ground, so that the entire inflatable device can be easily moved and used in different locations.

[0044] Specifically, the pressure monitor 14 is mainly used to monitor the pressure inside the inflation device in real time, sense changes in pressure, and transmit these signals. By operating the switch 13, the compressor 3 can be turned on or off. When it is necessary to inflate the aircraft tire, turn on the switch 13, the compressor 3 starts working, sucking in and compressing the outside air to provide an air source for the subsequent inflation process. The rotating frame 24 provides a rotating connection point for the runner 17, and the runner 17 can roll on the ground, so that the staff can easily move the inflation device to the vicinity of the aircraft tire that needs to be inflated.

[0045] Reference Figure 3 The right side of the shell 1 is fixedly connected with a card slot 18, which is used to provide a fixed connection point for convenient cooperation with other components to achieve specific functions. The left sides of the two wheel baffles 208 are fixedly connected with a buckle 19, which can be buckled with the card slot 18 to fix the wheel baffle 208 to one side of the shell 1 to prevent it from swinging at will. The right sides of the two wheel baffles 208 are fixedly connected with a soft pad 20, which can play a buffering role when the wheel baffle 208 contacts the aircraft tire, reducing the impact force of the contact between the two. The right sides of the two soft pads 20 are fixedly connected with a rubber pad 21, which can not only further enhance the buffering effect, but also increase the friction in contact with the tire, better block the tire, and prevent damage to the tire surface.

[0046] Specifically, when the wheel chock mechanism 2 is not in use, the wheel chock plate 208 is fixed to one side of the shell 1. This fixing method can make the wheel chock mechanism 2 neatly stored, and prevent the wheel chock plate 208 from swinging freely during the movement of the inflation device or other operations. When the wheel chock plate 208 blocks the aircraft tire, the soft cushion 20 can reduce the impact force when the wheel chock plate 208 contacts the tire, avoiding damage to the tire surface.

[0047] Working principle: When using the aircraft tire inflation device, the reinforcement plate 4 at the right end of the rear side of the shell 1 has two sliding grooves 6 equidistantly provided on the rear side of the reinforcement plate 4. A sliding block 7 is slidably connected in the sliding groove 6. The rear sides of the two sliding blocks 7 are fixedly connected to a movable splint 8, and the left end of the rear side of the reinforcement plate 4 is fixedly connected to a fixed splint 5. The adjacent side of the fixed splint 5 and the movable splint 8 is used to place the gas tank 9. The gas tank 9 can be easily installed and fixed by moving the movable splint 8. The compressed gas first reaches the gas tank 9 through the gas pipe 10. The connection port 11 on the top of the gas tank 9 is rotatably connected to ensure that the gas can smoothly enter the gas tank 9 from the gas pipe 10. When the gas pressure in the gas tank 9 reaches a certain level, the gas continues to be transmitted in the gas pipe 10 through the inflation port 12 under the action of pressure to inflate the aircraft tire. When it is necessary to block the aircraft tire, the horizontal plate 203 can be rotated to a suitable angle so that it is roughly aligned with the direction of the tire, and then the movable block 206 can be slid to adjust the distance between the two wheel blocking plates 208 to adapt to different tire sizes. After adjustment, the movable block 206 is fixed by the cooperation of the limiting bolt 207 and the limiting hole 205, so that the wheel blocking plate 208 remains stable, thereby effectively blocking the aircraft tire and preventing the tire from accidentally rolling during operations such as inflation.
