[0037] As Figures 1 to 7 As commonly shown, this embodiment provides a portable oxygen cylinder storage rack. This portable oxygen cylinder storage rack includes a bottom plate 1. A plurality of bottom rods 2 are vertically and fixedly installed on the bottom plate 1. The tops of the bottom rods 2 are fixedly connected by a first limit baffle 3. The first limit baffle 3 has a first U-shaped opening 301 for realizing the taking and placing and limiting of the oxygen cylinder.

[0038] An active rod 4 is slidably inserted along the axial direction of each bottom rod 2. The tops of the active rods 4 are fixedly connected by a second limit baffle 5. The second limit baffle 5 has a second U-shaped opening 501 for realizing the taking and placing and limiting of the oxygen cylinder. The second U-shaped opening 501 corresponds to the first U-shaped opening 301.

[0039] A sleeve 6 is fixedly installed at the top of the bottom rod 2. A screw rod 7 is rotatably installed in the sleeve 6. A positioning bolt 8 is also slidably installed in the sleeve 6 along the axial direction of the screw rod 7. The screw rod 7 is located inside the positioning bolt 8, and the screw rod 7 is in threaded fit with the positioning bolt 8. A plurality of positioning holes 401 adapted to the positioning bolt 8 are formed in the active rod 4. There are two positioning holes 401 on the active rod 4, which are respectively located at the bottom and top of the active rod 4. At the same time, the number of positioning holes 401 can be set according to actual use requirements to meet the purpose of positioning oxygen cylinders of different heights, such as Figure 1As shown, at this time, the positioning bolt 8 is located inside the positioning hole 401, which can reduce the volume of the storage rack and at the same time reduce its occupied area. At the same time, oxygen cylinders of slightly smaller specifications can also be placed in this state. When the positioning bolt 8 is located inside the second positioning hole 401, the storage rack can be unfolded to facilitate the placement of oxygen cylinders of adapted specifications;

[0040] An anti-tipping component for blocking the oxygen cylinder is provided between adjacent bottom rods 2 and / or between adjacent movable rods 4.

[0041] Movable wheels 9 are installed at the bottoms of two of the bottom rods 2, which can facilitate the transfer of the storage rack, and thus achieve the purpose of being easy to carry.

[0042] A knob 10 is provided outside the sleeve 6. The connecting end of the knob 10 extends into the sleeve 6 and is fixedly connected to one end of the screw rod 7. As Figure 3 shown, anti-slip strips for facilitating the operation of the operator's hand are installed on the surface of the knob 10.

[0043] The sleeve 6 has a chute communicating with the inner cavity of the bottom rod 2. The positioning bolt 8 and the chute are of a hexagonal structure adapted to each other. The positioning bolt 8 is slidably installed in the sleeve 6 through the chute. The positioning bolt 8 has an internal threaded hole adapted to the outer diameter of the screw rod 7. The screw rod 7 is installed in the positioning bolt 8 and is in threaded fit connection with the positioning bolt 8. In addition, the positioning bolt 8 and the chute can also be other polygonal structures to maintain the stability of the positioning bolt 8 during movement.

[0044] There are two groups of anti-tipping components. One group of anti-tipping components is located at the tops of two corresponding bottom rods 2, and the other group of anti-tipping components is located at the tops of two corresponding movable rods 4. And the two groups of anti-tipping components are respectively arranged on the open sides of the first U-shaped opening 301 and the second U-shaped opening 501.

[0045] The anti-tipping component includes a housing 11. The housing 11 is respectively fixedly installed on the inner sides of the bottom rod 2 and the movable rod 4. A winding shaft 12 is rotatably installed in the housing 11. A steel bottle lashing belt 13 is wound around the winding shaft 12. One end of the steel bottle lashing belt 13 is located outside the housing 11 and is connected with a plug 14. The plug 14 is provided with a slot 1401 along its length direction. Socket 15 corresponding to the housing 11 is also fixedly installed on the inner sides of the bottom rod 2 and the movable rod 4. The socket 15 has a T-shaped insertion part 1501 adapted to the slot 1401. The steel bottle lashing belt 13 is in a rolled structure, which can facilitate the positioning of the oxygen cylinder and prevent it from sliding out from the open ends of the first U-shaped opening 301 and the second U-shaped opening 501. The setting of the plug 14 can prevent the steel bottle lashing belt 13 from being completely located inside the housing 11.

[0046] The surface of the cylinder strap 13 is provided with a number of rubber anti-slip protrusions 1301. The rubber anti-slip protrusions 1301 are arranged evenly on the surface of the cylinder strap 13. The setting of the rubber anti-slip protrusions 1301 can increase the friction with the oxygen cylinder, make it more stable on the storage rack, and thus avoid the phenomenon of loosening or shaking.

[0047] One side of the second limiting baffle 5 is provided with a connecting block 16. A connecting hole 1601 is opened on the connecting block 16. A notch 502 corresponding to the connecting block 16 is opened on the other side of the second limiting baffle 5. A sleeve 17 is fixedly installed on the other side of the second limiting baffle 5. A sliding rod 18 is slidably installed in the sleeve 17. A blocking block 19 fixedly connected to one end of the sliding rod 18 is also slidably installed in the sleeve 17. A trapezoidal block 20 is fixedly connected to the side of the blocking block 19 away from the sliding rod 18. The sleeve 17 is provided with a first through hole for the trapezoidal block 20 to move through. A compression spring 21 is also arranged in the sleeve 17. The compression spring 21 is sleeved on the sliding rod 18, and the two ends of the compression spring 21 respectively abut against the sleeve 17 and the blocking block 19.

[0048] The sleeve 17 is provided with a second through hole for the sliding rod 18 to move through. The end of the sliding rod 18 away from the blocking block 19 extends out of the sleeve 17 through the second through hole and is installed with a pull ring 22. The pull ring 22 can facilitate the driving operation of the sliding rod 18.

[0049] During use, the knob 10 can be rotated in the reverse direction to drive the screw rod 7 to rotate, so that the positioning bolt 8 gradually disconnects from the positioning hole 401 at the bottom of the movable rod 4 as the screw rod 7 rotates. Until the two are completely disconnected, the limit between the movable rod 4 and the bottom rod 2 can be cancelled. Subsequently, the second limiting baffle 5 and the movable rod 4 will directly move down along the inside of the bottom rod 2 due to gravity. Then, the knob 10 can be rotated again to drive the screw rod 7 to rotate and drive the positioning bolt 8 to move towards the positioning hole 401 at the top of the movable rod 4 until the two are completely coincident, and the positioning operation between the movable rod 4 and the bottom rod 2 can be completed. The state at this time can be referred to Figure 1 to reduce the volume of the storage rack and its occupied space. At the same time, with the use of the moving wheels 9, it is convenient to carry and transport the storage rack;

[0050] At the same time, when positioning the oxygen cylinder, the insertion block 14 can be pulled to drive the cylinder strap 13 to move towards the socket 15. Then, the insertion block 14 is inserted into the inside of the T-shaped insertion part 1501 through the insertion slot 1401, and the positioning of the oxygen cylinder can be completed. At the same time, with the use of the rubber anti-slip protrusions 1301, the stability of the oxygen cylinder can be increased, and thus the phenomenon that the oxygen cylinder is separated from the storage rack due to factors such as shaking can be prevented;

[0051] In addition, when storing the storage rack, the connecting block 16 on one side of a group of second limiting baffles 5 can be located at the top of the notch 502 on the other side of another group of second limiting baffles 5. At the same time, the connecting block 16 is lowered along the inside of the notch 502. During this process, the connecting block 16 contacts the trapezoidal block 20, and at the same time, the trapezoidal block 20 moves towards the inside of the sleeve 17, and the trapezoidal block 20 pushes the stop block 19 and the sliding rod 18 towards the other end of the sleeve 17. At the same time, the stop block 19 squeezes the compression spring 21 and deforms it. When the connecting block 16 completely coincides with the notch 502, the trapezoidal block 20 is located on one side of the connecting hole 1601. At this time, the compression spring 21 restores its deformation and pushes the stop block 19 and the trapezoidal block 20 towards the outside of the sleeve 17 until the trapezoidal block 20 coincides with the connecting hole 1601, and the splicing operation of two or more groups of storage racks can be completed. Furthermore, the neatness during the storage of the storage rack can be increased. The state at this time can be referred to Figure 5 , by splicing and stacking multiple groups of retracted storage racks, more storage racks can be stored within a certain space, thereby increasing the storage quantity of the storage racks and avoiding the problem of limited storage quantity caused by excessive occupied area due to the large volume of the storage rack.

[0052] It should be understood that the use of these embodiments is only for illustrating the present invention and not for limiting the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications, and / or variations to the present invention, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
