[0028] like Figures 1 to 6 A detachable movable base of an oxygen concentrator comprises: a base body 1, a pulley 2, a positioning groove 3 and a positioning plate 4. The oxygen concentrator is placed on the base body 1, and the positioning groove 3 is symmetrically arranged on the upper surface of the base body 1.

A sliding groove 5 is symmetrically arranged inside the positioning plate 4, and a moving block 6 is slidably connected to the inside of the sliding groove 5. The lower side of one end of the moving block 6 extending out of the sliding groove 5 is provided with an inclined surface, and a spring 7 is fixedly connected to the side of the moving block 6 facing the sliding groove 5, and the end of the spring 7 away from the moving block 6 is fixedly connected to the inner wall of the sliding groove 5, and a pressing mechanism for pushing the moving block 6 is installed inside the base body 1, and a rotating mechanism is symmetrically installed at the bottom of the base body 1, and the pulley 2 is arranged in the rotating mechanism.

[0029] Furthermore, the pressing mechanism includes an assembly groove 8 and an extrusion block 9. The assembly groove 8 is opened inside the base body 1, and the positioning grooves 3 on both sides are connected to the assembly groove 8. Each assembly groove 8 is provided with an extrusion block 9, and the extrusion block 9 moves horizontally in the corresponding assembly groove 8 to push the moving block 6.

[0030] In this embodiment, the base body 1 is moved from bottom to top close to the bottom of the oxygen concentrator, the positioning groove 3 is slidably sleeved on the surface of the positioning plate 4, the moving block 6 is squeezed by the inner wall of the positioning groove 3, the moving block 6 is squeezed into the inside of the sliding groove 5, the moving block 6 squeezes the spring 7, the spring 7 is contracted, the lower surface of the positioning plate 4 contacts the inner wall of the positioning groove 3, the spring 7 is reset and opened, the moving block 6 enters the assembly groove 8 from both sides of the positioning groove 3, the positioning plate 4 is quickly connected to the base body 1, the two extrusion blocks 9 are close to each other along the inside of the assembly groove 8, the convex part of the extrusion block 9 squeezes the moving block 6, the moving block 6 is received into the inside of the sliding groove 5, the positioning plate 4 is moved out of the inside of the positioning groove 3, the base body 1 and the oxygen concentrator are quickly separated, and the base body 1 is convenient for disassembly, the bottom inclined surface of the moving block 6 contacts the inner wall of the positioning groove 3, the extrusion force is converted into a thrust to send the moving block 6 into the inside of the sliding groove 5, the positioning speed of the base body 1 and the positioning plate 4 is improved, the pulley 2 enables the base body 1 to have a mobile performance, and the rotating mechanism is convenient for the pulley 2 to be received into the inside of the base body 1.

[0031] As attached Figure 4As shown, the base body 1 is internally rotatably connected with a bidirectional screw rod 10, and the bidirectional screw rod 10 is threadedly connected to the extrusion blocks 9 on both sides, and simultaneously pushes the extrusion blocks 9 on both sides to move closer to or away from each other, and the two sides of the bidirectional screw rod 10 are fixedly connected with a first driving block 11.

[0032] In this embodiment, the first driving block 11 is rotated to drive the bidirectional screw 10 to rotate inside the assembly groove 8. The bidirectional screw 10 controls the two extrusion blocks 9 to approach each other along the inside of the assembly groove 8, providing drive for the movement of the extrusion blocks 9.

[0033] As attached Figure 4 As shown, the extrusion block 9 is a concave structure, and both ends of the extrusion block 9 are in contact with the moving blocks 6 on the two positioning plates 4 simultaneously when moving.

[0034] In this embodiment, when the extrusion block 9 contacts the moving blocks 6 on both sides, the two moving blocks 6 can be pushed into the interior of the sliding groove 5 at the same time. By rotating the first driving block 11 on either side of the bidirectional screw rod 10, the moving blocks 6 inside the assembly groove 8 can be sent into the interior of the sliding groove 5.

[0035] As attached Figure 4 As shown, the rotating mechanism includes a storage groove 12, a rotating plate 13, a limit rod 14 and a limit block 15. The storage groove 12 is symmetrically opened at the bottom of the base body 1, and the rotating plate 13 is rotatably connected to the inside of the storage groove 12. Two pulleys 2 are arranged at the bottom of each rotating plate 13. The limit rod 14 is slidably connected to the inner wall of the storage groove 12, and the limit rod 14 is perpendicular to the rotating plate 13. A rectangular groove is opened on the rotating plate 13 opposite to the limit rod 14. The limit rod 14 moves toward the rotating plate 13 and can extend into the rectangular groove to limit the rotation of the rotating plate 13. The limit block 15 is fixedly connected to the inner wall of the storage groove 12, and the limit block 15 is located above the rotating plate 13.

[0036] In this embodiment, the rotating plate 13 inside the receiving groove 12 is rotated to rotate the pulley 2 to the bottom of the base body 1, and the limiting rod 14 enters the rectangular groove on the surface of the rotating plate 13 to limit the rotating plate 13.

[0037] As attached Figure 5 and Figure 6 As shown, the rotating plate 13 is an L-shaped structure.

[0038] In this embodiment, when the limiting rod 14 enters the rectangular groove of the rotating plate 13, the L-shaped rotating plate 13 cannot rotate left or right. When the rotating plate 13 is flipped over and the limiting rod 14 squeezes the bottom of the rotating plate 13, the rotating plate 13 cannot rotate left or right in cooperation with the limiting block 15, which facilitates the limiting of the rotating plate 13.

[0039] As attached Figure 5 and Figure 6 As shown, the inner wall of the receiving groove 12 is rotatably connected with a one-way screw rod 16 , and the one-way screw rod 16 is threadedly connected to the limiting rod 14 , and the side of the one-way screw rod 16 away from the limiting rod 14 is fixedly connected with a second driving block 17 .

[0040] In this embodiment, the second driving block 17 is rotated to control the one-way screw 16 to rotate inside the storage groove 12. The one-way screw 16 controls the limit rod 14 to move toward the rotating plate 13. The second driving block 17 is rotated in the opposite direction to move the limit rod 14 away from the rotating plate 13, thereby providing drive for the movement of the limit rod 14.
