DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] A portable medical oxygen supply trolley case includes a case body 1, an oxygen tank 2, an oxygen delivery tube 3 and an oxygen inhaler 20. One end of the oxygen delivery tube 3 is connected to the oxygen tank 2 through the oxygen inhaler 20 to form an oxygen supply assembly. The oxygen supply assembly is stored in the case body 1, and the other end of the oxygen delivery tube 3 extends out of the case body 1. A delivery tube chute 4 is provided in the case body 1, and a shrinking assembly is slidably installed in the delivery tube chute 4. The oxygen delivery tube 3 is connected to the shrinking assembly, that is, the pipeline of the oxygen delivery tube 3 located in the case body 1 moves as the shrinking assembly slides, thereby changing the length of the oxygen delivery tube 3 extending out of the case body 1 by sliding the shrinking assembly in the case body 1. When using the oxygen supply assembly, the oxygen tank 2 and the user only need to be connected by pulling the oxygen delivery tube 3, thereby reducing the time required for connecting the oxygen supply assembly to the user and improving the convenience of use of the oxygen supply assembly.

[0023] The retraction assembly includes a guide rod 5 and a connecting sleeve 6. The guide rod 5 is slidably installed in the box body 1. The connecting sleeve 6 is rotatably installed on the guide rod 5 through a bearing. The oxygen delivery tube 3 is connected to the guide rod 5 through the connecting sleeve 6, that is, the middle part of the oxygen delivery tube 3 is wrapped around the connecting sleeve 6. When the guide rod 5 moves to the side where the oxygen delivery tube 3 extends out of the box body 1, most of the oxygen delivery tube 3 extends out of the box body 1. When the guide rod 5 moves to the side away from the side where the oxygen delivery tube 3 extends out of the box body 1, most of the oxygen delivery tube 3 retracts in the box body 1, that is, the length of the oxygen delivery tube 3 extending out of the box body 1 is changed by moving the guide rod 5; the setting of the connecting sleeve 6 can prevent sliding friction between the oxygen delivery tube 3 and the guide rod 5.

[0024] Guide grooves 7 are provided on the inner walls of both sides of the housing 1. Preferably, two guide grooves 7 are disposed on the inner sides of the upper housing 22 and the lower housing 21 of the housing 1, respectively, and are located on either side of the delivery tube chute 4. The ends of the guide rod 5 are slidably mounted within the housing 1 through the guide grooves 7. To facilitate the retraction of the extended oxygen delivery tube 3 into the housing 1, in this embodiment, return springs 11 are provided at the upper and lower ends of the guide rod 5. The return springs 11 are disposed on the side away from where the oxygen delivery tube 3 extends out of the housing 1, so that the return springs 11 can be used to retract the guide rod 5 into the housing 1.

[0025] To prevent the oxygen delivery tube 3 from retracting into the housing 1 due to the force of the return spring 11 during use, two limiting plates 8 are installed on the guide rod 5. A torsion spring 10 is provided between the two limiting plates 8. The torsion springs 10 are respectively connected to the two limiting plates 8. The two limiting plates 8 are stretched apart by the torsion springs 10. Limiting grooves 9 are provided on both sides of the delivery tube chute 4. The stretched limiting plates 8 abut against the guide grooves 7, thereby limiting and fixing the guide rod 5 in the delivery tube chute 4 of the housing 1. Preferably, the two limiting plates 8 are arranged at an angle so that when the oxygen delivery tube 3 extends out of the housing 1, the limiting plates 8 do not have a limiting function on the guide rod 5. When the oxygen delivery tube 3 is retracted into the housing 1, the limiting plates 8 abut against the limiting grooves 9 to limit the guide rod 5.

[0026] A support pad 12 is provided in the box body 1, and a tank body groove 13, a delivery pipe groove 23, a connecting groove 14 and an extension groove 15 are provided in the support pad 12. The tank body groove 13 is used to fix the oxygen tank 2, and the delivery pipe groove 23 is sleeved outside the delivery pipe chute 4. The tank body groove 13 and the delivery pipe groove 23 are connected by the connecting groove 14. The oxygen inhaler 20 is arranged in the connecting groove 14, and the extension groove 15 is connected to the delivery pipe groove 23. A through hole is provided on the box body 1 facing the extension groove 15, and the oxygen delivery pipe 3 extends out of the box body 1 through the extension groove 15.

[0027] The box body 1 includes a lower box body 21 and an upper box body 22 mounted on the lower box body 21 by a hinge. A buckle 16 is provided on one side of the upper box body 22, and a lap groove 17 adapted to the buckle 16 is provided on one side of the lower box body 21. The box body 1 can be opened and closed by cooperating with the buckle 16 and the lap groove 17; the support pad 12 is fixed in the lower box body 21.

[0028] Rollers 18 are installed on the outer side of the lower box body 21 to facilitate the movement of the box body 1. A handle 19 is connected to the lower box body 21 to facilitate the user to grab the box body 1.
