Traditional oxygen supply devices are often bulky, complex to operate, and prone to damage or affect oxygen supply during transportation, which greatly limits the flexibility and efficiency of emergency work. In order to solve this problem, an emergency oxygen supply device convenient for transportation has emerged. The original design of such a device is to minimize the size, simplify the operation, and enhance the portability and durability while ensuring the oxygen supply effect.

[0048] In the embodiment, the folding leg 24 can adopt a conventional structure on the market, or the following structure, including: a convex platform 219 connected to the bottom of the frame 21, the folding leg 24 being hinged to the convex platform 219, a limiting slot 211 being formed on the side opposite to the frame 21 of the folding leg 24, a first limiting hole 25 being further formed on the folding leg 24, the first limiting hole 25 vertically penetrating the limiting slot 211, one end of the limiting hole being connected to a first fixing nut 217; a limiting rod 26 being arranged at the bottom of the convex platform 219, one end of the limiting rod 26 being hinged to the frame 21, the other end of the limiting rod 26 being provided with a second limiting hole 212; the end of the limiting rod 26 being capable of extending into the limiting slot 211 to align the first limiting hole 25 with the second limiting hole 212, a limiting bolt 27 being capable of penetrating the first limiting hole 25 and the second limiting hole 212 to be connected to a second fixing nut 218.

[0052] Embodiment two:

[0053] Please refer to Figures 1-8In order to facilitate the transfer mechanism 2 is fixed on the transfer car to reduce the jolt, on the basis of the first embodiment, the device further comprises a fixed mechanism 1 arranged on the side wall 4 of the transfer car, the appearance of the transfer car is shown in Figure 8 The fixed mechanism 1 can be connected with the transfer mechanism 2 to fix the transfer mechanism 2 on the side wall 4 of the transfer car.

[0054] The fixed mechanism 1 in the embodiment comprises a fixed plate 14 fixed on the side wall 4 of the transfer car, a fixed block 11 connected on the fixed plate 14, vertical guide grooves 12 opened on both sides of the fixed block 11; a receiving cavity opened in the fixed block 11, a sliding plate 19 arranged in the receiving cavity, guide rods 13 arranged on both sides of the sliding plate 19, the guide rods 13 extending out of the fixed block 11 and vertically sliding along the guide grooves 12; one end of a compression spring 18 connected on the top of the sliding plate 19, the other end of the compression spring 18 fixed on the top of the fixed block 11; a clamping block 17 connected on the bottom of the sliding plate 19, the bottom of the clamping block 17 extending out of the fixed block 11; a clamping groove 23 opened on the handle 22 of the transfer mechanism 2, the clamping block 17 capable of extending into the clamping groove 23 to fix the transfer mechanism 2 on the fixed plate 14.

[0055] The handle 22 of the transfer mechanism 2 extends to the back of the frame 21, so that the end surface of the handle 22 is in the same plane with the outside of the folding leg 24. This arrangement can ensure that the handle 22 and the folding leg 24 are both attached to the fixed plate 14 when the transfer mechanism 2 is fixed with the fixed mechanism 1.

[0056] In addition, in order to strengthen the fixation of the transfer mechanism 2, the bottom of the fixed plate 14 is further connected with a fixed groove 15, the fixed groove 15 can extend into the space between the folding legs 24 after the transfer mechanism 2 is clamped with the fixed mechanism 1, and the clamping rod 16 can be connected with the fixed groove 15 through the gap between the folding legs 24 and the frame 21 to fix the transfer mechanism 2 and the bottom of the fixed mechanism 1.

[0057] In order to facilitate use, the bottom of the clamping block 17 is obliquely cut, so that the handle 22 can push the clamping block 17 backward to lift the clamping block 17 upward to make the clamping block 17 automatically fall into the clamping groove 23.

[0058] Method for use:

[0059] After the transfer mechanism 2 is transported to the transfer car, the transfer mechanism 2 is vertically placed, the clamping block 17 is pushed backward to lift the clamping block 17 upward, and then the clamping block 17 is clamped into the clamping groove 23 under the action of the compression spring 18, and then the clamping rod 16 is transversely inserted between the two folding legs 24 and the fixed groove 15 to realize simultaneous fixation up and down; when disassembling, the clamping rod 16 is pulled out, and then the guide rod 13 is pulled to realize the separation of the transfer mechanism 2 and the side wall 4 of the transfer car, so that the oxygen supply mechanism can be transported to the first-aid site.

[0060] Embodiment three:

[0061] Please refer to Figures 9-11 , in order to facilitate the transport mechanism 2 cooperation as Figure 11 in the emergency stretcher, on the basis of example one in the trolley handle 22 is provided with U-shaped card plate 221, U-shaped card plate 221 side of the vertical sliding slot 222 is provided with the fastening bolt 220, fastening bolt 220 is fixed in the trolley handle 22 side, trolley handle 22 top corresponding U-shaped card plate 221 place open groove 223, when not using U-shaped card plate 221 can be down to the groove 223 U-shaped card plate 221, does not affect the transport mechanism 2 and fixed mechanism 1 cooperation.

[0062] Example four:

[0063] Please refer to Figures 1-13 , in this embodiment, other parts are the same as example one, the difference is: when the oxygen supply device in example two is fixed on the transport trolley, because there is no support at the front end of the base 29, the wheel 28 will produce a torque as the pivot, which will cause the clamping groove 23 and the clamping block 17 to bear a large shear force, reducing the service life of the oxygen supply device. Therefore, in this embodiment, a support assembly is connected to the bottom of the base 29 of the frame 21. The support assembly includes a rotating rod 224 that penetrates the base 29. The rotating rod 224 is rotatably connected to the base 29. The two ends of the rotating rod 224 extend out of the base 29. The two ends of the rotating rod 224 are connected to support rods 225. The support rods 225 are bent in the middle, allowing them to tilt when supporting the ground. A counterweight rod 226 is connected between the tops of the support rods 225. The counterweight rod 226 has a magnetic block 228 in the middle, which can be magnetically connected to the oxygen cylinder in the oxygen supply mechanism 3. The bottoms of the support rods 225 support the ground when the support rods 225 are in the supporting state. The base 29 also has a clamping block 227 on the side. When the support rods 225 are in the storage state, the bottoms of the support rods 225 rest on the bottoms of the clamping blocks 227.

[0064] Principle of use:

[0065] In the transport state, i.e. the natural state, the support rods 225 will rest on the bottoms of the clamping blocks 227 due to the presence of the counterweight rod 226. At this time, the support rods 225 are parallel to the base 29. When support is needed, the counterweight rod 226 is pulled up, and the magnetic block 228 on the counterweight rod 226 is attracted to the oxygen cylinder. At this time, the support rods 225 are supported on the ground to form a support. The support rods 225 can be bent in the middle, allowing them to rest on the oxygen cylinder to form a support when supporting.
