Description

Technical Field

[0001] This utility model relates to the field of logistics transport rack technology, specifically to a folding-leg variable volume transfer rack. Background Technology

[0002] In the delivery of new energy drive axles or gearboxes, the performance of the transfer rack is crucial as a key tool for carrying and transporting goods. However, existing transfer racks have significant shortcomings. For example, the recyclable folding logistics transport rack disclosed in Chinese Patent Publication No. CN210503619U, while possessing some folding functionality, still has limitations in its overall structure. On the one hand, traditional transfer racks have a fixed structure. Although they can carry goods during delivery, their bulky size during retrieval occupies a large amount of space when transporting larger items such as new energy drive axles or gearboxes, significantly increasing transportation costs and resulting in high per-unit transportation and rack return freight. On the other hand, the folding structure of some foldable transfer racks lacks stability. During folding and unfolding, issues such as jamming and shaking can easily occur, affecting the user experience and making it difficult to ensure the stability of goods during transportation. In addition, some transfer racks are not precise enough in positioning goods, allowing goods to slide or shift on the rack, increasing the risk of damage to new energy drive axles or gearboxes during transportation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a flow-through shelf with folding legs and variable volume.

[0004] The technical solution adopted in this utility model is as follows: A folding-leg, volume-variable transfer shelf includes the following structure: The shelving frame includes a long side and a short side. A positioning block is provided at the upper edge of the long side. Uprights are provided on the inner side of the long side, and the uprights are symmetrically distributed on the inner side of the long side with the short side as the center. Folding brackets are installed at the four corners of the shelving frame. The folding brackets have support legs arranged sequentially from bottom to top. Limit sleeves are installed above the support legs, and support rods are hinged inside the limit sleeves. Limit blocks are provided on the outer side of the support rods, and grooves that match the limit blocks are provided on the limit sleeves. The limit sleeves also have notches facing the short side of the frame, and locking pins are provided on the side of the limit sleeves. The support rods are bent downwards at 90° along the notches and folded above the short side of the frame.

[0005] This technical solution improves the foldable support frame structure, combining it with the rack frame and positioning blocks to stably support goods during shipment and reduce rack height during retrieval by folding the support rods, thus minimizing space occupation. This achieves efficient switching between shipment and retrieval states, reducing the cost per unit and return shipping costs. Specifically, the rack frame provides a stable load-bearing structure, and the positioning blocks ensure precise placement of goods. The foldable support frame utilizes a hinged structure, allowing the support rods to rotate flexibly. Limiting blocks engage with grooves, and locking pins engage with elongated holes, ensuring stability of the support rods in both unfolded and folded states. The foldable support frame structure helps reduce costs. The steel structure has strong load-bearing capacity, is non-deformable, and reusable, reducing shipment costs. The foldable support frame reduces the overall height, lowering transportation costs during retrieval. For shipment, a medium-sized truck can transport five stacks of three-layer goods at a time, while a light truck can transport three stacks of five-layer racks during retrieval, increasing transport capacity. The rack state switching between shipment and retrieval is convenient and quick through simple support rod operations, such as rotation and pulling.

[0006] In addition, the folding-leg variable-volume transfer shelf proposed in this utility model may also have the following additional technical features: According to one embodiment of the present invention, the limiting sleeve covers at least three sides of the support leg, and its notch is an inclined V-shaped opening on the side of the limiting sleeve. The inclined V-shaped opening facilitates the bending and resetting operation of the support rod along the notch.

[0007] In this technical solution, the tilt angle of the inclined V-shaped notch guides the support rod along a predetermined trajectory when it bends, reducing friction and jamming, and making the bending process smoother. During resetting, the shape of the inclined V-shaped notch provides appropriate rebound or guiding force to help the support rod return to its initial position. The limiting sleeve wraps around multiple surfaces of the support leg, providing stable support, reducing swaying, and ensuring the structural stability of the shelving during use and folding.

[0008] According to one embodiment of the present invention, reinforcing beams are provided at intervals between the long sides of the frame, and the two ends of the reinforcing beams are fixedly connected to the long sides of the frame respectively.

[0009] In this technical solution, when the long side of the frame is under stress, the reinforcing beam can distribute part of the force to other parts, change the force distribution path, and make the stress on the entire frame more uniform.

[0010] According to one embodiment of the present invention, there are several positioning blocks, which are evenly distributed on the upper edge of the long side of the frame and are used to position the assembly placed on the shelf.

[0011] In this technical solution, the evenly distributed positioning blocks can form multiple fixed positioning points. When the assembly is placed, these positioning points can constrain the assembly from different directions, restricting its horizontal movement and rotation, and preventing the assembly from sliding or shifting on the shelf.

[0012] According to one embodiment of the present invention, a hanging rack for carrying goods is provided with the bottom of the long side of the frame facing downwards, and the hanging rack is arranged in a U-shape.

[0013] In this technical solution, the U-shaped opening of the hanging rack can better fit the shape of the goods and play a certain restraining role in the horizontal direction to prevent the goods from slipping off.

[0014] According to one embodiment of the present invention, the hanger and the long side of the frame are integrally formed; or, the hanger is fixed to the bottom of the long side of the frame by bolts.

[0015] This technical solution provides two methods—one-piece molding or bolt connection—to achieve a stable connection between the hanger and the long side of the frame, ensuring that the hanger can reliably support items.

[0016] According to one embodiment of the present invention, the limiting block is a protrusion with an elliptical cross-section; the groove is an elongated hole structure that cooperates with the limiting block.

[0017] In this technical solution, the elliptical limiting block and the elongated groove cooperate, with a large contact area in the long axis direction, which can reliably limit the movement of the component and prevent it from excessively deviating; the structure is simple, the limiting block and the groove are relatively easy to process, and the positioning is accurate during installation.

[0018] Compared with the prior art, this utility model has the following advantages: (1) When shipping and recycling, the rack state can be changed by simply rotating and pulling the support rod, which is convenient and quick. It can also increase the transport loading capacity and reduce the single unit transport cost and rack return freight.

[0019] (2) The folding bracket utilizes a hinged structure, allowing the support rod to rotate flexibly. The inclined V-shaped notch guides the bending and resetting more smoothly. The support rod can be folded above the short side of the frame, reducing the height of the shelf, reducing space occupation, and reducing transportation costs.

[0020] (3) The positioning blocks evenly distributed on the upper edge of the long side of the frame form multiple fixed positioning points, which constrain the goods from different directions, restrict their horizontal movement and rotation, prevent the goods from sliding and shifting on the shelf, and achieve precise placement.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1 like Figures 1 to 3 As shown, this embodiment provides a flow-forwarding shelf with folding legs and variable volume, including the following structure: The shelving frame includes a long side 1 and a short side 10. A positioning block 3 is provided on the upper edge of the long side 1. An upright 5 is provided on the inner side of the long side 1, and the upright 5 is symmetrically distributed on the inner side of the long side 1 with the short side 10 as the center. Folding brackets are installed at the four corners of the shelf frame. The folding brackets are provided with support legs 6 from bottom to top. Limiting sleeves 7 are installed above the support legs 6. Support rods 9 are hinged inside the limiting sleeves 7. Limiting blocks 8 are provided on the outer side of the support rods 9. The limiting sleeves 7 are provided with grooves that match the limiting blocks 8. The limiting sleeves 7 are also provided with notches facing the short side 10 of the frame. Locking pins are provided on the side of the limiting sleeves 7. The support rods 9 are bent downwards at 90° along the notches and folded above the short side 10 of the frame.

[0027] like Figures 1 to 3As shown, this technical solution improves the foldable support frame structure, and in conjunction with the shelf frame and positioning block 3, etc., it stably supports goods during delivery and reduces the shelf height by folding the support rod 9 during retrieval, thus reducing space occupation and achieving efficient conversion between delivery and retrieval states, reducing the transportation cost per unit and the return freight of the shelf. Specifically, the shelf frame provides a stable load-bearing structure, and the positioning block 3 enables precise placement of goods; the foldable bracket utilizes a hinge structure, allowing the support rod 9 to rotate flexibly, and the limiting block 8 cooperates with the groove, and the locking pin cooperates with the elongated hole to ensure the stability of the support rod 9 in both unfolded and folded states; the foldable support frame structure helps to reduce costs; the steel structure has strong load-bearing capacity, does not deform, and can be reused, reducing delivery costs; the foldable support frame reduces the overall height, reducing transportation costs during retrieval; when delivering, a medium-sized truck can transport five stacks of three-layer goods at a time, and when retrieval, a light truck can transport three stacks of five-layer shelves, increasing the transportation loading capacity; during delivery and retrieval, the shelf state can be converted through simple operations of the support rod 9, such as rotation and pulling, which is convenient and quick.

[0028] In addition, the folding-leg variable-volume transfer shelf proposed in this utility model may also have the following additional technical features: According to one embodiment of the present invention, the limiting sleeve 7 covers at least three sides of the support leg 6, and its notch is an inclined V-shaped opening opened on the side of the limiting sleeve 7. The inclined V-shaped opening facilitates the bending and resetting operation of the support rod 9 along the notch.

[0029] In this technical solution, the tilt angle of the inclined V-shaped notch guides the support rod 9 to move along a predetermined trajectory when it bends, reducing friction and jamming, and making the bending process smoother. During resetting, the shape of the inclined V-shaped notch provides appropriate rebound or guiding force to help the support rod 9 return to its initial position. The limiting sleeve 7 wraps around multiple surfaces of the support leg 6, providing stable support, reducing swaying, and ensuring the structural stability of the shelving during use and folding.

[0030] According to one embodiment of the present invention, reinforcing beams 4 are provided at intervals between the long sides 1 of the frame, and the two ends of the reinforcing beams 4 are fixedly connected to the long sides 1 of the frame respectively.

[0031] In this technical solution, when the long side 1 of the frame is under stress, the reinforcing beam 4 can distribute part of the force to other parts, change the force distribution path, and make the stress on the entire frame more uniform.

[0032] According to one embodiment of the present invention, there are several positioning blocks 3, which are evenly distributed on the upper edge of the long side 1 of the frame, and are used to position the assembly placed on the shelf.

[0033] In this technical solution, the evenly distributed positioning blocks 3 can form multiple fixed positioning points. When the assembly is placed, these positioning points can constrain the assembly from different directions, restricting its horizontal movement and rotation, and preventing the assembly from sliding or shifting on the shelf.

[0034] According to one embodiment of the present invention, a hanging rack 2 for carrying goods is provided with the bottom of the long side 1 of the frame facing downwards, and the hanging rack 2 is arranged in a U-shape.

[0035] In this technical solution, the U-shaped opening of the hanging bracket 2 can better fit the shape of the goods and play a certain restraining role in the horizontal direction to prevent the goods from slipping.

[0036] According to one embodiment of the present invention, the hanging bracket 2 and the long side 1 of the frame are integrally formed; or, the hanging bracket 2 is fixed to the bottom of the long side 1 of the frame by bolts.

[0037] This technical solution provides two methods, namely integral molding or bolt connection, to achieve a stable connection between the hanger 2 and the long side 1 of the frame, ensuring that the hanger 2 can reliably support items.

[0038] According to one embodiment of the present invention, the limiting block 8 is a protrusion with an elliptical cross-section; the groove is an elongated hole structure that cooperates with the limiting block 8.

[0039] In this technical solution, the elliptical limiting block 8 cooperates with the elongated groove, and the contact area in the long axis direction is large, which can reliably limit the movement of the component and prevent it from excessively deviating; the structure is simple, the limiting block 8 and the groove are relatively easy to process, and the positioning is accurate during installation.

[0040] The usage process of the above embodiments is as follows: like Figures 1 to 3 As shown, during shipment, the goods are placed on the shelf frame. The positioning blocks 3 evenly distributed on the upper edge of the long side 1 of the frame form multiple positioning points, constraining the goods from different directions and preventing them from sliding or shifting. The uprights 5 symmetrically distributed on the inner side of the long side 1 of the frame and the reinforcing beams 4 spaced apart between the long side 1 of the frame enhance the stability and load-bearing capacity of the frame. The U-shaped hanging bracket 2 with the bottom of the long side 1 of the frame facing downward conforms to the shape of the goods and prevents the goods from slipping. At this time, the support rod 9 of the folding bracket is in the unfolded state. The elliptical limiting block 8 on the outer side of the support rod 9 is embedded in the long slot groove of the limiting sleeve 7. The locking pin on the side of the limiting sleeve 7 fixes the support rod 9 to ensure its stable support. During recycling, the locking pin is pulled out, and the support rod 9 bends downward 90° along the inclined V-shaped notch on the side of the limiting sleeve 7 and folds above the short side 10 of the frame, reducing the overall height of the shelf, reducing space occupation, facilitating transportation with light trucks, and realizing efficient conversion between the shipment and recycling states.

Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope of the claims.
