Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and in particular to a foldable shelving unit that is convenient for transportation. Background Technology

[0002] To improve the efficiency of racking transportation in the current logistics field, there are attempts to adopt modular and detachable racking designs. These racks typically design the support legs, platform, and side panels as independent, separate structures, which are assembled and fixed on-site using bolts, pins, and other connectors. While theoretically reducing transportation volume, significant drawbacks have been found in practical applications: First, many small connectors (such as screws and clips) in the modular structure are easily lost or damaged during repeated disassembly and assembly, preventing complete racking assembly. Second, on-site assembly requires aligning each connecting hole and tightening bolts individually, a time-consuming and tool-dependent process that significantly reduces warehousing efficiency. Third, the connection nodes of the modular structure are prone to stress concentration when bearing cargo loads, leading to localized deformation or loosening, resulting in stability far lower than that of a one-piece molded structure. Therefore, while detachable designs have potential for space saving, their inherent defects, such as poor reliability and cumbersome operation, make them unsuitable for the needs of high-frequency logistics scenarios.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a foldable shelf that is convenient for transportation, in order to solve the technical problem that the existing shelves are difficult to combine space saving, convenient transportation and operation, and high reliability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foldable shelf that is easy to transport includes: a carrier plate, four support legs and two side brackets. The four support legs are fixedly connected to the four corners of the carrier plate, and the two side brackets are symmetrically arranged on both sides of the carrier plate. Each side bracket can be folded and snapped onto two adjacent support legs.

[0007] Each support leg includes a receiving groove and a hinge shaft. The two side walls of the receiving groove at the same end are provided with slots. The hinge shaft passes through the two side walls of the receiving groove and is located directly below the slots.

[0008] The lower end of the side bracket is housed in the receiving groove of the support foot, and a snap-fit ​​post is provided at the position corresponding to the snap-fit ​​groove. The snap-fit ​​post is detachably connected to the snap-fit ​​groove. An elongated hole is provided below the snap-fit ​​post for accommodating the hinge shaft.

[0009] When the shelf is used to load goods, the side guard is perpendicular to the carrier plate, the snap-fit ​​post is inserted into the bottom of the slot, and the hinge shaft is located in the upper middle part of the elongated hole to achieve stable fixation of the side guard; when the shelf is not in use, the snap-fit ​​post is disengaged from the slot, the hinge shaft moves to the bottom of the elongated hole, and the side guard is folded inward around the hinge shaft until it is parallel to the carrier plate, so that the entire shelf is folded into a compact form that is close to a plate.

[0010] The aforementioned foldable shelf for easy transport includes a side support frame comprising two vertical bars and two horizontal bars, the two horizontal bars being a first horizontal bar and a second horizontal bar respectively. The upper ends of the two vertical bars are fixedly connected via the first horizontal bar, and the lower ends of the two vertical bars are connected via the second horizontal bar. The lower ends of the vertical bars are accommodated in a receiving groove.

[0011] The aforementioned foldable shelf for easy transportation, wherein the elongated hole and the snap-fit ​​post are both located at the lower end of the vertical rod, the elongated hole is a through hole, and two snap-fit ​​posts are provided on one vertical rod, the two snap-fit ​​posts being located on the two sides of the vertical rod where the elongated hole opening is located respectively.

[0012] The aforementioned foldable shelving for easy transportation includes a support leg that also includes a limiting rod. The two ends of the limiting rod are fixedly connected to the two side walls of the receiving groove, and the limiting rod is located below the hinge shaft to limit the lower end of the vertical rod.

[0013] In the aforementioned foldable shelf designed for easy transport, when the hinge shaft is located in the upper middle part of the elongated hole, the distance between the hinge shaft and the bottom of the elongated hole is greater than the depth of the slot, and the distance between the limiting rod and the carrier plate is less than or equal to the depth of the slot.

[0014] The aforementioned foldable shelving unit, which is convenient for transportation, has a splicing part at the lower end of the support legs. When multiple shelving units are stacked in a folded state, the splicing part of the upper shelving unit can be inserted into the receiving slot of the lower shelving unit to limit and fix the two adjacent shelving units.

[0015] The aforementioned foldable shelving unit, which facilitates transportation, includes a side support frame with reinforcing bars at both ends, which are fixedly connected to two crossbars.

[0016] The foldable shelf that is easy to transport includes a side shelf that also includes a lifting ring, which is fixedly connected to the middle of the second crossbar and located on the side of the second crossbar away from the first crossbar.

[0017] Beneficial effects:

[0018] This utility model provides a foldable shelf for convenient transportation, including a carrier plate, support legs, and side panels.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0031] Please see Figures 1 to 3 As shown, this utility model provides a foldable shelf that is convenient for transportation, which includes: a carrier plate 1, four support legs 2 and two side brackets 3. The four support legs 2 are respectively fixedly connected to the four corners of the carrier plate 1, and the two side brackets 3 are symmetrically arranged on both sides of the carrier plate 1. Each side bracket 3 can be folded and snapped onto two adjacent support legs 2. In this embodiment, the carrier plate 1 is a square metal plate, and the carrier plate 1 and the support legs 2 are fixedly connected by welding.

[0032] Each support leg 2 includes a receiving groove 21 and a hinge shaft 22. The two side walls of the receiving groove 21 at the same end are provided with slots 23. The hinge shaft 22 passes through the two side walls of the receiving groove 21 and is located directly below the slots 23. In this embodiment, the upper end of the receiving groove 21 and the side near the carrier plate 1 are provided with openings. The slots 23 are provided at the upper end of the receiving groove 21. The two ends of the hinge shaft 22 are fixed to the two side walls by nuts.

[0033] The lower end of the side baffle 3 is housed in the receiving groove 21 of the support foot 2, and a snap-fit ​​post 31 is provided at the position corresponding to the snap-fit ​​groove 23. The snap-fit ​​post 31 is detachably connected to the snap-fit ​​groove 23. An elongated hole 32 is provided below the snap-fit ​​post 31 to accommodate the hinge shaft 22. In this embodiment, the snap-fit ​​post 31 is fixedly connected to the side of the lower end of the side baffle 3 by welding. The elongated hole 32 is a through hole, and the line connecting the openings at both ends of the through hole is parallel to the axis of the snap-fit ​​post 31. The length of the elongated hole 32 is greater than the depth of the snap-fit ​​groove so that the snap-fit ​​post can disengage from the snap-fit ​​groove when the side baffle moves upward relative to the support foot.

[0034] When the shelf is used to load goods, the side support 3 is perpendicular to the carrier plate 1. Under its own weight, the lower end of the side support 3 naturally inserts into the receiving groove 21, the locking post 31 is engaged with the bottom of the locking groove 23, and the hinge shaft 22 is located in the upper middle part of the elongated hole 32 to achieve stable fixation of the side support 3. When the shelf is not in use, the side support 3 needs to be lifted upwards to disengage the locking post 31 from the locking groove 23, and the hinge shaft 22 is moved to the bottom of the elongated hole 32. Then, the side support 3 is folded inwards around the hinge shaft 22 until it is parallel to the carrier plate 1, so that the entire shelf is folded into a compact form close to a plate. This convenient foldable shelf has all components connected as one unit in both folded and unfolded states, solving the problem of easy loss of parts in traditional detachable shelves. Folding and unfolding operations are very convenient and quick, and it can be folded into a compact structure close to a plate, saving space and making it more conducive to transportation and storage.

[0035] Please see Figure 1 As shown, the side support 3 includes two vertical rods 33 and two horizontal rods, namely a first horizontal rod 34 and a second horizontal rod 35. The upper ends of the two vertical rods 33 are fixedly connected via the first horizontal rod 34, and the lower ends of the two vertical rods 33 are connected via the second horizontal rod 35. The lower ends of the vertical rods 33 are accommodated in the receiving groove 21. In this embodiment, the vertical rods 33 and the horizontal rods are fixedly connected by welding. The length of the first horizontal rod 34 is equal to the length of the second horizontal rod 35 and less than the side length of the carrier plate 1. The lengths of the two vertical rods 33 are equal and their total length is less than the side length of the carrier plate 1, so that when both side supports 3 are folded, they remain on the same plane and do not interfere with each other.

[0036] Please see Figures 1 to 3 As shown, both the elongated hole 32 and the locking pin 31 are located at the lower end of the vertical rod 33. Two locking pins 31 are provided on each vertical rod 33, located at the two ends of the opening of the elongated hole 32 on the sides of the vertical rod 33. During folding, when the vertical rod 33 rotates around the hinge axis 22, the two locking pins 31 simultaneously disengage from the slot 23, and the contact point between the inner wall of the elongated hole 32 and the hinge axis 22 moves from the upper middle part of the hole to the bottom of the hole. During this process, the two locking pins 31 act as guide bosses, preventing the vertical rod 33 from shifting laterally within the receiving groove 21.

[0037] Please see Figures 1 to 3As shown, the support foot 2 also includes a limiting rod 24. The two ends of the limiting rod 24 are fixedly connected to the two side walls of the receiving groove 21, and the limiting rod 24 is located below the hinge shaft 22 to limit the lower end of the vertical rod 33. In this embodiment, the limiting rod 24 is fixed to the support foot 2 by welding. The limiting rod 24 blocks the opening side of the receiving groove 21, further limiting the lower end of the vertical rod 33 housed in the receiving groove 21, preventing the side support frame 3 from tilting inwards under gravity, thereby reducing the pressure of the locking post 31 on the side wall of the locking groove 23. The limiting rod 24 is positioned lower than the hinge shaft 22 to prevent interference with the vertical rod 33 when the side support frame 3 is folded, thus avoiding affecting the folding effect.

[0038] In this embodiment, when the hinge shaft 22 is located in the upper middle part of the elongated hole 32, the distance between the hinge shaft 22 and the bottom of the elongated hole 32 is greater than the depth of the slot 23, and the distance between the limiting rod 24 and the carrier plate 1 is less than or equal to the depth of the slot 23. This avoids the situation where the locking post 31 cannot disengage from the slot 23 when the hinge shaft 22 reaches the bottom of the elongated hole 32, or the vertical rod 33 is blocked by the limiting rod 24, thereby affecting the folding function of the shelf.

[0039] Please see Figures 1 to 4 As shown, the lower end of the support leg 2 is provided with a splicing part 25. When multiple shelves are stacked in a folded state, the splicing part 25 of the upper shelf can be inserted into the receiving slot 21 of the lower shelf to limit and fix the two adjacent shelves. In this embodiment, the splicing part 25 is a quadrangular prism adapted to the inner wall of the receiving slot 21. The splicing part 25 is formed by protruding downward from the bottom end face of the support leg 2. The length of the splicing part 25 is less than the distance between the top of the receiving slot 21 and the highest surface of the side guard 3 when folded. When the splicing part 25 of the upper shelf is inserted into the receiving slot 21 of the lower shelf, the bottom end face of the support leg 2 of the upper shelf contacts the top end face of the receiving slot 21 of the lower shelf, avoiding the weight of the upper shelf from directly acting on the side guard 3 of the lower shelf, thereby preventing the connection structure between the side guard 3 of the lower shelf and the support leg 2 from failing. The design of the splicing part 25 can limit and lock the stacked shelves to prevent them from tipping over during transportation and causing safety accidents.

[0040] Please see Figure 1 As shown, the side guard 3 also includes reinforcing rods 37, with both ends of the reinforcing rods 37 fixedly connected to the two crossbars respectively. In this embodiment, one side guard 3 has two reinforcing rods 37, and both reinforcing rods 37 are fixedly connected to the two crossbars by welding to enhance the stability of the side guard 3.

[0041] Please see Figure 1As shown, the side support 3 also includes a lifting ring 36, which is fixedly connected to the middle of the second crossbar 35 and located on the side of the second crossbar 35 away from the first crossbar 34. In this embodiment, the lifting ring 36 is fixedly connected to the second crossbar 35 by welding. When the shelf is in a folded state, the two lifting rings 36 are symmetrically arranged on both sides of the carrier plate 1. The shelf can be moved by grabbing the lifting rings 36. Whether it is handled manually or mechanically, it is more conducive to grabbing and positioning, and prevents the shelf from slipping and falling.

[0042] In summary, this utility model achieves rapid switching between the shelf's working and folded states through the vertical locking of the snap-fit ​​post 31 on the side baffle 3 and the snap-fit ​​groove 23 of the support foot 2, combined with the adaptive sliding of the hinge shaft 22 within the elongated hole 32 of the side baffle 3. This design overcomes the limitations of traditional detachable shelves that rely on separate assembly; all components are always connected to the carrier plate 1, avoiding the risk of losing parts; folding and unfolding operations are simple and quick; and the compact plate-like structure formed after folding saves storage space, achieving full-process space optimization for transportation and storage.
