The first limiting long plate 20 and the second limiting long plate 21 are both slidably installed inside the supporting upright plate 16, and connected by a handle 15. The inclusion of a storage component, a height adjustment component, a fixing component, and a first positioning component allows the storage component to store folded outdoor clothing, the height adjustment component to easily adjust the usage height of the storage component, the fixing component to secure the storage component, and the first positioning component to position the storage component. When using this device to store folded outdoor clothing, the device's usage height can be adjusted, avoiding the difficulty of adjusting the usage height due to a fixed height, and making the height adjustment process convenient.
[0024] When in use, the initial state of this device is as follows: the device is placed on the ground and the bottom of the heavy-duty support base plate 7 is in contact with the ground. The heavy-duty support base plate 7 has a certain weight to prevent the device from tipping over. The open-type storage box body 5 is located in the middle of the support plate 16. The first screw 14 is threadedly connected to the open-type storage box body 5 and the top of the open-type storage box body 5 is closed. The second screw 4 is threadedly connected to the first threaded groove 6 and the third screw 19 is threadedly connected to the second threaded groove 25.
[0025] When this device is needed to store folded outdoor clothing, rotate the first screw 14 to disengage it from the open-type storage box body 5 and position one end of the first screw 14 inside the outer cover 13. Pull the handle 15 upward to disengage the outer cover 13 from the open-type storage box body 5, allowing the inner cover 22 to slide out from inside the open-type storage box body 5. When the inner cover 22 has completely slid out from inside the open-type storage box body 5, and when the outer cover 13 is disengaged from the support plate 16, the top of the open-type storage box body 5 is opened. Move the folded outdoor clothing and place it inside the open-type storage box body 5.
[0026] After enough folded outdoor clothing is placed inside the open-type storage box body 5, the outer box cover 13 contacts the open-type storage box body 5, allowing the inner box cover 22 to enter the interior of the open-type storage box body 5. The first screw 14 is rotated in the opposite direction, causing the first screw 14 to be threadedly connected to the open-type storage box body 5, thus closing the top of the open-type storage box body 5. Under the action of the open-type storage box body 5, the open-type storage box body 5 can store the folded outdoor clothing. At this time, this device can be used to store the folded outdoor clothing.
[0027] When using this device to store folded outdoor clothing, if the user needs to lift the device, the user should hold the handle 17. The handle 17 will allow the user to lift the device.
[0028] When using this device to store folded outdoor clothing, if the device needs to be adjusted in height, rotate the second screw 4 to disengage it from the first threaded groove 6 and allow one end of the second screw 4 to enter the interior of the connecting rod 3. Move the connecting rod 3 vertically so that the connecting rod 3, the connecting plate 2, and the first L-shaped plate 1 all slide vertically along the support plate 16. This allows the first limiting plate 20, the open storage box body 5, and the second limiting plate 21 to slide vertically along the support plate 16. This allows the inner box cover 22, the outer box cover 13, the first screw 14, and the handle 15 to move vertically.

[0029] With the connecting rod 3, connecting plate 2, and first L-shaped plate 1 all sliding vertically along the supporting plate 16, and with the first limiting plate 20, open-type storage box body 5, and second limiting plate 21 all sliding vertically along the supporting plate 16, and with the inner box cover 22, outer box cover 13, first screw 14, and handle 15 all moving vertically, and with the first limiting plate 20, open-type storage box body 5, and second limiting plate 21 all sliding vertically along the supporting plate 16, the usable height of the open-type storage box body 5 can be changed, preventing it from being fixed and allowing for easy adjustment of its usable height.
[0030] When the working height of the open-type storage box body 5 is the required working height, and when the second screw 4 corresponds to the first threaded groove 6, the second screw 4 is rotated in the opposite direction to make the second screw 4 threadedly connected to the first threaded groove 6. At this time, the working height of the device can be adjusted.
[0031] In summary, when using this device to store folded outdoor clothing, the device's operating height can be adjusted, avoiding the difficulty of adjusting the operating height due to a fixed height. This makes the device easy to adjust.
[0032] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown: An outdoor supplies storage box includes a first limiting plate 20, a second limiting plate 21, an arc-shaped support block 12, and an L-shaped rod 8. A lifting component to improve the practicality of the storage component is fixedly installed on one side of the storage assembly. The lifting component includes the arc-shaped support block 12, one side of which is fixedly installed on one side of the open-type storage box body 5. A support shaft 26 is fixedly connected to the other side of the arc-shaped support block 12. An arc-shaped support plate 11 is rotatably connected to the outer surface of the support shaft 26. The arc-shaped support plate 11 is rotatably connected to both the open-type storage box body 5 and the arc-shaped support block 12. A positioning semi-column 23 is fixedly connected to one side of the arc-shaped support plate 11. The positioning semi-column 23 is movably installed inside the body of the open-type storage box 5. There are two curved support plates 11. A limiting component for the lifting assembly is fixedly installed on one side of the lifting assembly. The limiting component includes an L-shaped rod 8. One side of the L-shaped rod 8 is fixedly installed on the side of the curved support block 12 away from the support shaft 26. The other side of the L-shaped rod 8 has a second threaded groove 25 and a third threaded groove 10 respectively. The L-shaped rod 8 is fixedly connected to the first L-shaped long plate 1. The side of the L-shaped rod 8 away from the curved support block 12 is rotatably connected to the second L-shaped long plate 18. The second L-shaped long plate 18 is fixedly connected to the curved support plate 11. The second L-shaped long plate 18 is rotatably connected to the first L-shaped long plate 1. A third screw 19 is threadedly connected inside the plate body of the second L-shaped long plate 18. The third screw 19 is threadedly connected to the second threaded groove 25 and the third threaded groove 10, respectively. A second positioning component is fixedly installed on one side of the lifting assembly. The second positioning component includes a support column 24. One end of the support column 24 is fixedly installed on the side of the L-shaped rod 8 away from the arc-shaped support block 12, and the other end of the support column 24 is fixedly connected to a limit column 9. Both the support column 24 and the limit column 9 are rotatably connected to the second L-shaped long plate 18. Through the arrangement of the lifting assembly, the limit component, and the second positioning component, the lifting assembly... This device enhances the practicality of the storage components, enabling the limiting component to limit the lifting component and the second positioning component to position the lifting component. When using this device to store folded outdoor clothing, if the two sides of the device need to be used as temporary tabletops, the two sides can be extended. This prevents the two sides from being unable to be used as temporary tabletops due to the inability to extend them further, thus avoiding the increased difficulty of using the two sides as temporary tabletops. This device makes it convenient to use the two sides as temporary tabletops.
[0033] When using this device to store folded outdoor clothing, if it is necessary to use the two sides of the device as a temporary table, rotate the third screw 19 to disengage the third screw 19 from the second threaded groove 25 and position one end of the third screw 19 inside the body of the L-shaped rod 8. Rotate the second L-shaped long plate 18 so that it rotates along the L-shaped rod 8, the support column 24, the limiting column 9, and the first L-shaped long plate 1. This causes the arc-shaped support plate 11 to rotate along the open-type storage box body 5, the arc-shaped support block 12, and the support shaft 26, causing the positioning half-column 23 to rotate out from inside the body of the open-type storage box body 5.
[0034] When one side of the arc-shaped support plate 11 rotates to the same plane as the top of the open-type storage box body 5, the arc-shaped support plate 11 rotates from a vertical state to a horizontal state. One side of the second L-shaped long plate 18 is on the same plane as the top of the L-shaped rod 8. The third screw 19 corresponds to the third threaded groove 10. Stop rotating the third screw 19 and rotate it in the opposite direction so that the third screw 19 is threadedly connected to the third threaded groove 10. Under the action of one side of the arc-shaped support plate 11 rotating to the same plane as the top of the open-type storage box body 5, and under the action of the arc-shaped support plate 11 rotating from a vertical state to a horizontal state, the two arc-shaped support plates 11 can be unfolded. Under the action of the two arc-shaped support plates 11 being able to unfold, the two sides of the open-type storage box body 5 can be further unfolded, so that the two sides of the open-type storage box body 5 can be used as temporary tabletops. At this time, the two sides of this device can be used as temporary tabletops.
[0035] In summary, by incorporating the lifting component, the limiting component, and the second positioning component, when using this device to store folded outdoor clothing, the sides of the device can be additionally unfolded when needed to function as temporary tabletops. This prevents the sides from being unable to function as temporary tabletops due to the inability to unfold them further, thus avoiding the increased difficulty of using the sides as temporary tabletops. Ultimately, this device facilitates the use of both sides as temporary tabletops.
