Description

Technical Field

[0001] This utility model relates to the field of storage frame technology, and more specifically, to a storage frame that is easy to use. Background Technology

[0002] In existing technologies, storage boxes have some functional limitations and user experience issues in actual use. These defects severely restrict the practicality and flexibility of the products. Specifically, most storage boxes in existing technologies are designed as single-function static storage containers that can only be fixed in a specific location for storing items. They cannot be converted into integrated storage devices through simple assembly. This single usage mode forces users to repeatedly move items when they need to move them frequently, which not only increases labor intensity but also reduces work efficiency. The user experience is particularly poor, especially in scenarios where multiple items need to be stored or long distances need to be moved.

[0003] A more prominent problem is that the assembly and disassembly of existing storage boxes and connecting rods are often not user-friendly, requiring complex steps or special tools. Traditional connection methods are not only cumbersome and time-consuming, but also often result in weak or overly tight connections due to poor design, making disassembly difficult. This is especially true when the connection point is in a difficult-to-access location, where users often need multiple tools or specific operating angles to assemble or disassemble, severely impacting the product's ease of use. This inconvenience in assembly and disassembly prevents the storage box system from being quickly and flexibly adjusted according to actual needs, such as when users temporarily need to increase or decrease storage capacity. When faced with items of different sizes and shapes, it is difficult to quickly adjust the number of storage boxes; when dealing with items of different sizes and shapes, it is impossible to reconfigure the storage combination as needed; in space-constrained environments, it is also difficult to flexibly change the arrangement of storage boxes according to the available space. This lack of adaptability makes it difficult for the product to meet diverse and changing storage needs. In addition, due to the difficulty of assembly and disassembly, users also face many inconveniences when cleaning and maintaining the storage boxes, and it is impossible to thoroughly clean the dirt on the connecting parts. Long-term use may lead to hygiene problems or damage to the connecting parts. These design flaws ultimately lead to a shortened product lifespan, reduced user satisfaction, and a significant reduction in functional value. Utility Model Content

[0008] The present invention is further configured such that a first connecting rod is detachably provided on the lower side of the storage frame, the top end of the first connecting rod is fixedly connected to the locking rod, and the bottom end of the first connecting rod is fixedly connected to the locking sleeve. This design enables the storage frame to form a stable modular structure with the connecting rod, which is convenient for multi-layer stacking and assembly, thereby increasing the overall load-bearing capacity and ensuring the flexibility of disassembly and assembly, thus meeting different storage needs.

[0009] The present invention is further configured such that a second connecting rod is detachably provided below the bottommost storage box, and a universal wheel is detachably connected to the bottom end of the second connecting rod. This design enables the entire storage system to move, so users do not need to repeatedly move the stored items, but only need to push the universal wheel to achieve convenient movement, which greatly reduces labor intensity and improves efficiency.

[0010] The present invention is further configured such that the rolling groove is a concave structure design, which ensures that the locking ball can roll smoothly along a predetermined trajectory during the unlocking and locking process, preventing the locking ball from disengaging and improving the reliability of the mechanism operation.

[0011] The present invention is further configured such that the locking groove is formed in an annular structure on the outside of the locking rod. This annular design allows the locking ball to be uniformly stressed and firmly locked from any angle, which enhances the stability of the connection structure and simplifies the assembly process, eliminating the need to consider angle alignment issues.

[0012] The present invention is further configured such that a locking plate is fixedly provided at one end of the locking sleeve, and the elastic plate slides through the locking plate. This design forms a reliable guiding mechanism, ensuring that the elastic plate moves along the correct path during operation, thereby improving the accuracy and smoothness of unlocking and locking actions.

[0013] The present invention is further configured such that a support spring is connected to one side of the release sleeve, and the other end of the support spring is connected to the bottom end of the first connecting rod. This elastic connection mechanism ensures that the release sleeve can automatically reset after operation without manual adjustment, while providing appropriate operating resistance to prevent accidental unlocking, thereby improving the safety and convenience of product use.

[0014] The present invention is further configured such that the outer wall of the release sleeve adopts a rounded corner structure design, and the moving block adopts an arc-shaped column structure design.

[0029] Please see Figures 1-5A user-friendly storage frame includes a storage frame 1. A retaining sleeve 2 is detachably provided on one side of the storage frame 1. A retaining rod 3 is detachably provided in the retaining sleeve 2. A retaining groove 4 is provided on the outer side of the retaining rod 3. A release sleeve 5 is slidably fitted on the outer side of the retaining sleeve 2. A limiting groove 6 and a release groove 7 are provided on the inner side of the release sleeve 5. A rolling groove 8 is provided on the side wall of the retaining sleeve 2. A retaining ball 9 rolls in the rolling groove 8. A portion of the retaining ball 9 is inserted into the retaining groove 4. A movable plate 10 is movably provided on one side of the retaining sleeve 2. A plurality of elastic plates 11 are connected to one side of the movable plate 10. A movable block 12 is fixedly connected to one side of the elastic plate 11.

[0030] The storage box 1 is detachably provided with a first connecting rod 13 on the lower side. The top end of the first connecting rod 13 is fixedly connected to the locking rod 3, and the bottom end of the first connecting rod 13 is fixedly connected to the locking sleeve 2.

[0031] A second connecting rod 14 is detachably provided below the bottom storage box 1, and a caster wheel 15 is detachably connected to the bottom of the second connecting rod 14.

[0032] In this embodiment, when the device is needed, the corresponding number of storage boxes 1 and other components can be selected and assembled together to form a movable cart. Then, the items can be stored in each storage box 1. When the device needs to be moved, it can be moved by the universal wheels 15 set at the bottom of the second connecting rod 14, making it more convenient to use.

[0033] Please see Figures 3-5 As a further implementation of the overall equipment: the rolling groove 8 has a concave structure design.

[0034] The locking groove 4 is a ring structure and is opened on the outside of the locking rod 3.

[0035] The locking sleeve 2 has a locking plate 16 fixed at one end, and the elastic plate 11 slides through the locking plate 16.

[0036] A support spring 17 is connected to one side of the release sleeve 5, and the other end of the support spring 17 is connected to the bottom end of the first connecting rod 13.

[0037] The outer wall of the release sleeve 5 adopts a rounded corner structure design, and the moving block 12 is an arc-shaped column structure design.

[0038] More specifically, when the storage box 1 needs to be disassembled, first push the release sleeve 5 upwards. The release sleeve 5 will cooperate with the bottom end of the first connecting rod 13 to squeeze the support spring 17. The release sleeve 5 will also drive the inner limiting groove 6 and release groove 7 to slide upwards. At the same time, the rounded corner structure on the outer side of the release sleeve 5 will push the moving block 12 outwards. Then the moving block 12 will drive the elastic plate 11 to tilt outwards. When the release groove 7 moves to the position corresponding to the rolling groove 8, the outer wall of the locking ball 9 is no longer limited. Then, the release sleeve 5 and the locking sleeve 2 are pulled upwards together, so that the locking sleeve 2 drives the locking ball 9 to move through the rolling groove 8. Then the inner wall of the locking groove 4 squeezes the outer wall of the locking ball 9. Due to the spherical structure design of the locking ball 9, the locking ball 9 will gradually move out of the locking groove. The ball 9 rolls out of the rolling groove 8, and a portion of the ball 9 enters the release groove 7, thus separating the locking sleeve 2 and the locking rod 3. Then, the moving plate 10 is pulled down, causing the moving block 12 to slide via the elastic plate 11, moving it to the other side of the release sleeve 5. The elastic plate 11 then moves the moving block 12 back to its original position, releasing the release sleeve 5. The support spring 17 pushes the release sleeve 5 to slide back to its original position, placing the moving block 12 between the release sleeve 5 and the locking plate 16. During this process, the release sleeve 5 moves the inner limiting groove 6 and the release groove 7 back to their original positions. The limiting groove 6 then presses the ball 9 inward, causing it to roll along the rolling groove 8... After the inner side is rolled back, the other locking sleeves 2 are removed one by one according to the above steps. Then, the storage frame 1 can be removed from the first connecting rod 13. When it is necessary to assemble the storage frame 1 and the first connecting rod 13 together, place the storage frame 1 above the first connecting rod 13, and make the locking rod 3 at its top pass through the reserved mounting hole on the outside of the storage frame 1. Then, the locking sleeve 2 is directly fitted onto the outside of the locking rod 3 from above. Then, one side of the moving plate 10 first fits against the upper surface of the storage frame 1, so that the moving plate 10 no longer moves. Then, the elastic plate 11 on one side of the moving plate 10 and the moving block 12 on one side of the elastic plate 11 no longer move. Then, the moving block 12 will abut the release sleeve 5, so that the release sleeve 5 no longer moves. Then, the release sleeve 5 and the first connecting rod 13 connected above it are connected. The connecting rod 13 presses against the support spring 17, and the release sleeve 5 will again drive the inner limiting groove 6 and release groove 7 to slide, so that the position of the release groove 7 moves again to the position corresponding to the rolling groove 8. Then, the conical block at the top of the locking rod 3 will push the locking ball 9 outward, so that the locking ball 9 rolls outward along the rolling groove 8, so that part of the locking ball 9 enters the release groove 7. When the locking sleeve 2 is completely fitted onto the outside of the locking rod 3, the locking groove 4 moves to the position corresponding to the rolling groove 8. Then, the pushing force of the support spring 17 is greater than the force applied by the elastic plate 11. Then, the support spring 17 pushes the release sleeve 5 to slide back to its original position. Then, the rounded corner structure on the outside of the release sleeve 5 pushes the moving block 12 outward. Then, the moving block 12 drives the elastic plate 11 to tilt outward again.Then, the release sleeve 5 will cause the inner limiting groove 6 and the release groove 7 to slide and reset. The limiting groove 6 will then press the locking ball 9 inward again, causing it to roll inward along the rolling groove 8 until it enters the locking groove 4. The support spring 17 will then fully reset, and the release sleeve 5 will fully reset and move to the side of the moving block 12. The elastic plate 11 will then drive the moving block 12 back to its original position, thus achieving convenient assembly between the storage frame 1 and the first connecting rod 13.

[0039] In summary, when using or operating the device: when the device is needed, the corresponding number of storage boxes 1 and other components can be selected and assembled together to form a movable cart. Then, the items can be stored in each storage box 1. When the device needs to be moved, it can be moved by the casters 15 set at the bottom of the second connecting rod 14, making it more convenient to use.

[0040] When the storage box 1 needs to be disassembled, first push the release sleeve 5 upwards. The release sleeve 5 will cooperate with the bottom end of the first connecting rod 13 to squeeze the support spring 17. The release sleeve 5 will also drive the inner limiting groove 6 and release groove 7 to slide upwards. At the same time, the rounded corner structure on the outer side of the release sleeve 5 will push the moving block 12 outwards. Then the moving block 12 will drive the elastic plate 11 to tilt outwards. When the release groove 7 moves to the position corresponding to the rolling groove 8, the outer wall of the locking ball 9 is no longer limited. Then, the release sleeve 5 and the locking sleeve 2 are pulled upwards together, so that the locking sleeve 2 drives the locking ball 9 to move through the rolling groove 8. Then the inner wall of the locking groove 4 squeezes the outer wall of the locking ball 9. Due to the spherical structure design of the locking ball 9, the locking ball 9 will gradually roll out of the locking groove 4. The locking ball 9 rolls outward along the rolling groove 8, causing a portion of it to enter the release groove 7. This separates the locking sleeve 2 and the locking rod 3. Then, the moving plate 10 is pulled down, causing it to slide via the elastic plate 11 onto the moving block 12, which moves to the other side of the release sleeve 5. The elastic plate 11 then moves the moving block 12 back to its original position, releasing the release sleeve 5. The support spring 17 pushes the release sleeve 5 to slide back to its original position, placing the moving block 12 between the release sleeve 5 and the locking plate 16. During this process, the release sleeve 5 moves the inner limiting groove 6 and the release groove 7 back to their original positions. The limiting groove 6 then presses the locking ball 9 inward, causing it to roll inward along the rolling groove 8. After resetting the device, remove the other locking sleeves 2 one by one according to the above steps. Then, remove the storage frame 1 from the first connecting rod 13. When it is necessary to assemble the storage frame 1 and the first connecting rod 13 together, place the storage frame 1 above the first connecting rod 13, and make the locking rod 3 at its top pass through the reserved mounting hole on the outside of the storage frame 1. Then, directly fit the locking sleeve 2 onto the outside of the locking rod 3 from above. Then, one side of the moving plate 10 first adheres to the upper surface of the storage frame 1, so that the moving plate 10 no longer moves. Then, the elastic plate 11 on one side of the moving plate 10 and the moving block 12 on one side of the elastic plate 11 no longer move. Then, the moving block 12 will abut the release sleeve 5, so that the release sleeve 5 no longer moves. Then, the release sleeve 5 and the first connecting rod connected above it... 13. When the support spring 17 is compressed, the release sleeve 5 will again drive the inner limiting groove 6 and release groove 7 to slide, so that the release groove 7 moves again to the position corresponding to the rolling groove 8. Then, the conical block at the top of the locking rod 3 will push the locking ball 9 outward, so that the locking ball 9 rolls outward along the rolling groove 8, so that part of the locking ball 9 enters the release groove 7. When the locking sleeve 2 is completely fitted onto the outside of the locking rod 3, the locking groove 4 moves to the position corresponding to the rolling groove 8. Then, the pushing force of the support spring 17 is greater than the force applied by the elastic plate 11. Then, the support spring 17 pushes the release sleeve 5 to slide back to its original position. Then, the rounded corner structure on the outside of the release sleeve 5 pushes the moving block 12 outward. Then, the moving block 12 drives the elastic plate 11 to tilt outward again.Then, the release sleeve 5 will cause the inner limiting groove 6 and the release groove 7 to slide and reset. The limiting groove 6 will then press the locking ball 9 inward again, causing it to roll inward along the rolling groove 8 until it enters the locking groove 4. The support spring 17 will then fully reset, and the release sleeve 5 will fully reset and move to the side of the moving block 12. The elastic plate 11 will then drive the moving block 12 back to its original position, thus achieving convenient assembly between the storage frame 1 and the first connecting rod 13.
