Technical Field

[0001] This utility model relates to the field of furniture, specifically a foldable storage rack that requires no installation. Background Technology

[0002] Shelves are a type of "three-dimensional storage" furniture that utilizes unused vertical spaces such as walls, countertops, cabinets, and even ceilings to create load-bearing shelves / hanging baskets, thereby increasing storage capacity and reducing clutter. They are found in almost every setting, including homes, offices, supermarkets, and industrial warehouses, resulting in a wide variety of materials, structures, and functional forms. Desktop shelves are primarily composed of a base and support columns, featuring an open design. Main materials include chrome-plated carbon steel, wood, plastic, and stainless steel, with modular assembly achieved through strip-shaped supports.

[0003] However, most current shelving units are modular, with all accessories and brackets shipped separately for users to assemble themselves using bolts. This makes it easy for accessories to be missing or damaged during shipping, and users are prone to assembling them incorrectly or even damaging the accessories. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an installation-free foldable storage rack, which solves the problems mentioned in the background.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-5 As shown, this embodiment provides a foldable storage rack that requires no installation, including a rack body 1. The rack body 1 includes a vertical support rod 2 and a diagonal support rod 3. The length of the diagonal support rod 3 is greater than the length of the vertical support rod 2. A pivot 301 is connected to the upper ends of the vertical support rod 2 and the diagonal support rod 3. The vertical support rod 2 and the diagonal support rod 3 are movably connected by the pivot 301. An embedded groove is formed on the side surface of the diagonal support rod 3 located on one side, and the side surface of the pivot 301 is located inside the embedded groove. The device is equipped with a ratchet 302. A limiting slot 303 is provided on the inner side wall of the embedded groove. A screw cap 6 is provided inside the embedded groove. A limiting pawl 601 is connected to the inside of the screw cap 6 through an elastic rotating shaft. The limiting pawl 601 is engaged with the ratchet 302. A locking washer 602 is installed on the outer side wall of the screw cap 6 at the position corresponding to the limiting slot 303. The screw cap 6 is movably connected to the limiting slot 303 through the locking washer 602. The limiting pawl 601 is movably connected to the screw cap 6.

[0019] like Figure 2-3 As shown, in this embodiment, an upper tray 4 is installed on the upper inner side of the vertical support rod 2, and a lower tray 5 is installed below the upper tray 4 on the inner wall of the vertical support rod 2. The length of the lower tray 5 is greater than that of the upper tray 4. The upper tray 4 and the lower tray 5 are connected to the diagonal brace 3 by a movable shaft. An acrylic pad 401 is installed inside the upper tray 4 and the lower tray 5. The acrylic pad 401 is fixedly connected to the upper tray 4 and the lower tray 5. A first support crossbar 304 is installed on the side surface of the diagonal brace 3 corresponding to the lower position of the upper tray 4. A second support crossbar 305 is installed on the inner side of the diagonal brace 3 corresponding to the lower position of the lower tray 5. The first support crossbar 304 and the second support crossbar 305 are fixedly connected to the diagonal brace 3.

[0020] The working principle of this utility model is as follows: During production and use, the vertical support rod 2 and the diagonal support rod 3 are fixedly installed together via a rotating shaft 301. The upper tray 4 and the lower tray 5 are also connected to the inner wall of the vertical support rod 2 via a movable shaft. The first support crossbar 304 and the second support crossbar 305 are then fixedly installed inside the diagonal support rod 3. At the same time, the screw cap 6 is installed inside the recessed groove on the side surface of the diagonal support rod 3, so that the locking pad ring 602 on the outer side of the screw cap 6 is embedded in the limiting slot 303 inside the recessed groove. The limiting pawl 601 inside the screw cap 6 is then locked on the outer side of the ratchet 302. When folding and storage are required, the upper tray 4 at the top position is swung upwards from the inside of the vertical support rod 2. The limiting pawl 601 inside the screw cap 6 is then pushed outwards to disengage from the limiting of the ratchet 302. The diagonal support rod 3 is then folded upwards via a rotating shaft 301. Shaft 301 continues to rotate with the vertical support rod 2, folding the upper tray 4 inwards towards the vertical support rod 2 for storage. As the diagonal support rod 3 continues to rotate outwards, the obstruction and limitation of the lower tray 5 by the second support crossbar 305 is broken. The lower tray 5 is then rotated from the lower end of the vertical support rod 2 and folded inwards. The diagonal support rod 3 is then rotated as a whole and stored on the outside of the vertical support rod 2. Thus, the entire diagonal support rod 3 is stored on the outside of the vertical support rod 2, realizing the folding of the entire shelf body 1 into a flat structure for easy storage and delivery. When it needs to be unfolded, the one-way limiting pawl 601 and ratchet 302 inside the screw cap 6 can ensure the stability of the support when the vertical support rod 2 and diagonal support rod 3 are unfolded, preventing the vertical support rod 2 and diagonal support rod 3 from collapsing under pressure after supporting items are placed on the upper tray 4 and lower tray 5.
