Technical Field

[0001] This utility model relates to a metal shelf, and more particularly to a metal shelf with a folding function. Background Technology

[0002] Metal shelving is an indispensable piece of equipment in modern warehousing, retail, and logistics industries, widely favored for its durability, high load-bearing capacity, and ease of installation and maintenance. In warehouses, shelving is often necessary for the efficient storage of large quantities of goods. However, traditional metal shelving has some shortcomings:

[0003] 1. Large size and inconvenient to move: Traditional shelving is usually connected by bolts and screws, resulting in a large overall size that is inconvenient to move and store.

[0004] 2. Complex disassembly and assembly: Although traditional shelves can be disassembled, the disassembly and assembly process is quite complicated, requiring additional time and tools, which makes it very inconvenient to store and rearrange.

[0005] 3. Poor flexibility: Due to its fixed structure, traditional shelving is not flexible enough when adjusting its layout or changing its use, making it difficult to quickly adapt to the ever-changing needs within the warehouse. Utility Model Content

[0006] To overcome the aforementioned shortcomings, the technical problem to be solved is to provide a metal shelf with a folding function.

[0007] The technical solution of this utility model is as follows: a metal shelf with folding function, including support plates, mounting seats, telescopic plates, lifting sleeves, telescopic components, locking components, and locking components. There are twelve support plates, with four support plates on each layer, arranged in a rectangular pattern. Four rectangular connecting plates are provided on the uppermost support plate. Lifting sleeves are slidably connected inside each support plate. The lifting sleeves are connected to the support plate on the next layer above them, and the uppermost lifting sleeve is connected to the uppermost connecting plate. A mounting seat is provided between every two symmetrical support plates, and a mounting seat is also provided between every two symmetrical connecting plates. The two sides of the mounting seat are rotatably connected to the two sides of the support plate or the connecting plate, respectively. Telescopic plates are connected between the inner sides of the two mounting seats on the same layer. Locking components are provided on the connecting plates, telescopic components are provided on the mounting seats, and locking components are provided on the support plates.

[0008] As a further preferred embodiment, the telescopic assembly includes a sleeve, a screw, a telescopic rod, and a knob. A sleeve is connected to one side of each of the rear mounting seats, and a screw is rotatably connected to one side of each of the front mounting seats. The screw is threaded to the inner side of the sleeve on the same layer. A telescopic rod is connected between the right sides of each of the two mounting seats on the same layer. The telescopic rod and the sleeve on the same layer are symmetrically distributed, and the telescopic rod, sleeve, and screw are all located inside the telescopic plate. The front end of each screw passes through a support plate or connecting plate on the same side, and a knob is connected to the front end of each screw.

[0009] As a further preferred embodiment, the locking assembly includes a fixed rod, a pin, a movable frame, and a first spring. The upper sides of the two connecting plates on the left are rotatably connected to the fixed rod, and the upper sides of the two connecting plates on the right are slidably connected to the movable frame. Two first springs are connected between the movable frame and the corresponding connecting plate. Two pins are connected to the upper side of the movable frame. U-shaped grooves are opened on the upper sides of the two connecting plates on the right. The fixed rod engages with the U-shaped grooves, and the pins are slidably inserted into the upper sides of the two connecting plates on the right. Two slots that engage with the pins are opened at the right end of the fixed rod.

[0010] As a further preferred option, both the support plate and the lifting sleeve are provided with multiple mounting holes, which are aligned with each other.

[0011] As a further preferred embodiment, the locking assembly includes a support frame, a second spring, and a locking rod. The support frame is connected to the outer side of the support plate, and the locking rod is slidably connected to the support frame. The second spring is connected between the locking rod and the support frame, and the locking rod engages with the mounting hole.

[0012] As a further preferred option, it also includes casters, with casters installed on the bottom of the four support plates on the lowest layer.

[0013] The beneficial effects are: 1. By releasing the fixing rod from the connecting plates and support plates on both sides, the telescopic plate can be rotated into a tilted state by pressing down the connecting plate and support plate on the right side, thereby folding the entire shelf, greatly reducing the space occupied. This not only makes it easier to handle, but also makes it easy to store when not in use, effectively saving storage space.

[0014] 2. The shelf is equipped with retractable extension panels for storing items. By turning the knob, the screw can be moved forward or backward to adjust the length of the extension panels. This allows the storage space of the shelf to be increased or decreased according to actual needs, enabling the shelf to adapt to the storage needs of goods of different sizes and quantities, thus improving the flexibility of warehousing.

[0015] 3. The upper and lower telescopic panels are connected by a lifting sleeve, and the height of the lifting sleeve can be adjusted to change the height of each telescopic panel to accommodate items of different heights and avoid space waste caused by excessively large or small spacing between layers.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0024] Example: A metal shelf with folding function, such as Figures 1-6As shown, it includes a support plate 1, casters 2, mounting base 3, telescopic plate 4, lifting sleeve 14, telescopic assembly, locking assembly, and locking assembly. There are twelve support plates 1, with four support plates 1 on each layer, arranged in a rectangular pattern. Four rectangular connecting plates 101 are installed on the uppermost support plate 1. Lifting sleeves 14 are slidably connected to each support plate 1. Each lifting sleeve 14 is connected to the support plate 1 on the layer above it, and the uppermost lifting sleeve 14 is connected to the uppermost connecting plate 101. Each left... Mounting seats 3 are provided between the two right-symmetrical support plates 1, and mounting seats 3 are also provided between the two left-right symmetrical connecting plates 101. The left and right sides of the mounting seats 3 are rotatably connected to the sides of the support plates 1 or connecting plates 101 respectively. The inner sides of the two mounting seats 3 on the same layer are connected to telescopic plates 4 for storing items. The bottom of the four support plates 1 on the bottom layer are all equipped with casters 2 to facilitate the movement of the shelf. The connecting plates 101 are equipped with locking components, the mounting seats 3 are equipped with telescopic components, and the support plates 1 are equipped with locking components.

[0025] like Figures 3-4 As shown, the telescopic assembly includes a sleeve 5, a screw 6, a telescopic rod 7, and a knob 8. The left front part of the rear mounting base 3 is welded with a sleeve 5, and the left rear part of the front mounting base 3 is rotatably connected with a screw 6. The screw 6 is threaded to the inside of the sleeve 5 on the same layer. The right side of the two mounting bases 3 on the same layer is connected with a telescopic rod 7. The telescopic rod 7 and the sleeve 5 on the same layer are symmetrically distributed on the left and right. The telescopic rod 7, sleeve 5, and screw 6 are all located inside the telescopic plate 4. The front end of the screw 6 passes through the support plate 1 or connecting plate 101 on the same side, and the front end of each screw 6 is welded with a knob 8.

[0026] like Figure 5 As shown, the locking assembly includes a fixed rod 10, a pin 11, a movable frame 12, and a first spring 13. The fixed rod 10 is rotatably connected to the upper side of the two connecting plates 101 on the left, and the movable frame 12 is slidably connected to the upper side of the two connecting plates 101 on the right. Two first springs 13 are connected between the movable frame 12 and the corresponding connecting plate 101. Two pins 11 are welded to the upper side of the movable frame 12. U-shaped grooves are opened on the upper side of the two connecting plates 101 on the right. The fixed rod 10 is engaged with the U-shaped grooves, and the pins 11 are slidably inserted into the upper side of the two connecting plates 101 on the right. Two slots are opened on the right end of the fixed rod 10 to engage with the pins 11. The fixed rod 10 locks the connecting plates 101 on both sides, keeping them at the same height.

[0027] like Figure 6As shown, the locking assembly includes a support frame 16, a second spring 17, and a locking rod 19. Both the support plate 1 and the lifting sleeve 14 have multiple mounting holes 15, which are aligned with each other. The support plate 1 is welded to the outside of the support frame 1, and the locking rod 19 is slidably connected to the support frame 16. The second spring 17 is connected between the locking rod 19 and the support frame 16. The locking rod 19 engages with the mounting holes 15. By inserting the locking rod 19 into the mounting holes 15 on the support plate 1 and the lifting sleeve 14, the lifting sleeve 14 can be fixed on the support plate 1.

[0028] Goods are stored on the telescopic shelves 4, which have four layers. When the length of the telescopic shelves 4 needs to be adjusted, it can be achieved by turning the knob 8. Turning the knob 8 forward or backward will drive the screw 6 to rotate. Since the screw 6 and the sleeve 5 are connected by threads, the screw 6 can move forward or backward, thereby causing the telescopic shelves 4 and their matching telescopic rods 7 to extend or shorten. At the same time, the support plate 1 and the connecting plate 101 located on the front side will also move forward or backward with the movement of the telescopic shelves 4. The casters 2 assist the entire structure to move smoothly. In this way, the storage capacity of the shelf can be flexibly adjusted by extending or shortening the telescopic shelves 4.

[0029] If the height of each telescopic plate 4 needs to be adjusted, the user can first pull the corresponding locking rod 19 outward to compress the second spring 17. Once the locking rod 19 is dislodged from the mounting hole 15, the lifting sleeve 14 will become loose. At this time, the lifting sleeve 14 can be freely slid up and down to adjust the height of the telescopic plate 4. After the height adjustment is completed, ensure that the mounting hole 15 on the lifting sleeve 14 is aligned with the mounting hole 15 on the support plate 1. Then release the locking rod 19 and use the restoring force of the second spring 17 to allow the locking rod 19 to be reinserted into the mounting hole 15, thereby fixing the position of the lifting sleeve 14. This method allows the user to adjust the distance between the telescopic plates 4 according to actual needs in order to store items of different heights.

[0030] When the shelf needs to be folded and stored, first push the movable frame 12 inward, causing the pin 11 to move inward. The first spring 13 is then compressed, and the pin 11 disengages from the slot on the fixed rod 10. Then, rotate the fixed rod 10 upward to disengage it from the U-shaped groove on the right connecting plate 101, releasing the lock on the left and right connecting plates 101. After that, release the movable frame 12, and the pin 11 and movable frame 12 will automatically reset under the action of the first spring 13. Next, push the right connecting plate 101 downward, causing its individual support plate 1 to descend and the mounting base 3 to tilt, finally fitting into the support plate 1 on the left. The telescopic plate 4 also tilts accordingly, realizing the overall folding of the shelf. To unfold the folded shelf, first pull the connecting plate 101 and support plate 1 on the right side outward and lift them upward until the support plates 1 and connecting plate 101 on both sides are on the same horizontal plane. The mounting base 3 and telescopic plate 4 will also return to the horizontal position. Finally, re-insert the right end of the fixing rod 10 into the U-shaped groove on the right connecting plate 101 and ensure that the pin 11 is correctly inserted into the slot on the fixing rod 10 to ensure that the support plates 1 and connecting plate 101 on both sides are kept at the same height and are securely locked.
