Description

Technical Field

[0001] This utility model belongs to the field of pallet technology, specifically relating to foldable and unfoldable pallets with railings. Background Technology

[0002] Pallets are used in the production of mattresses and other products. In practical applications, it's desirable for pallets to be able to be quickly stacked when loaded with goods and quickly folded up when empty, and then stacked again. Currently, empty pallets can generally be stacked but not folded, or folded but not stacked. Summary of the Invention

[0003] This invention addresses the shortcomings of existing pallets that cannot be folded or unfolded for stacking by providing a pallet with a fence that can be folded and unfolded for stacking. It can be stacked not only when unfolded but also when folded.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a foldable and unfoldable pallet with a guardrail, wherein the foldable and unfoldable pallet with a guardrail comprises:

[0005] Support plate;

[0006] Stacking supports are located below the support plate;

[0007] Folding legs, located above the support plate;

[0008] Fence;

[0009] Among them, the relatively folding legs of the fence can switch between being vertically unfolded and horizontally folded;

[0010] Among them, stacking holes are opened at the lower end of the stacking support feet to fit both the folding support feet and the upper end of the fence;

[0011] When the fence is erected and unfolded, the stacking holes of the stacking legs of the upper pallet fit over the upper end of the fence of the lower pallet, thus enabling unfolding and stacking.

[0012] When the fence is folded flat, the stacking holes of the stacking legs of the upper pallet fit over the upper end of the folding legs of the lower pallet, achieving folding stacking.

[0013] This utility model relates to a pallet with a guardrail. The guardrail and its folding legs can switch between vertical unfolding and horizontal folding. When the guardrail is vertically unfolded, the stacking holes of the upper pallet's stacking legs fit over the upper end of the lower pallet's guardrail, enabling unfolded stacking. When the guardrail is horizontally folded, the stacking holes of the upper pallet's stacking legs fit over the upper end of the lower pallet's folding legs, enabling folded stacking. Unfolded and folded stacking are achieved by changing the position of the guardrail. When the guardrail is vertically unfolded, it can limit the movement of mattresses. After the guardrail is vertically unfolded, the pallets can be stacked sequentially to form a storage rack, making full use of vertical space. Pallets are stacked from bottom to top during storage and retrieved from top to bottom during retrieval.

[0014] As an improvement, the folding legs have insertion holes. When unfolding and stacking, the lower end of the fence is inserted into the insertion hole; when folding and stacking, the lower end of the fence is removed from the insertion hole. When the lower end of the fence is inserted into the insertion hole, the fence is unfolded vertically, and the fence can only be raised and lowered relative to the insertion hole. When folding and stacking is required, the fence is lifted and then rotated to a flat folding position, at which point the fence is lower than the folding legs.

[0015] As an improvement, the upper end of the folding leg is a stacking insertion part that is adapted to the stacking hole. The stacking insertion part has a notch that communicates with the insertion hole. The notch is located above the insertion hole and has a vertical groove for inserting the fence and a horizontal groove for folding the fence. The folding leg and the fence are connected by a pin. The folding leg and / or the fence have long grooves that are movable relative to the pin.

[0016] As an improvement, the folding legs are provided with pin holes, and the fence is provided with long slots, with the pins located in the pin holes and long slots.

[0017] As an improvement, the notch slot is a through slot that runs horizontally through the folding plane of the fence.

[0018] As an improvement, the outer end of the pin is a rivet head, and the inner end is bent.

[0019] As an improvement, the support plate is one piece, there are four stacking legs, four folding legs, and two fences that are parallel when upright and unfolded.

[0020] As an improvement, the four folding legs are divided into two groups, with the upper surface of the insertion hole of one group of folding legs being lower than the upper surface of the insertion hole of the other group of folding legs. The two fences are connected to the two groups of folding legs respectively.

[0021] As an improvement, the lower end of the fence is a spherical surface, and / or the upper end of the socket is a constricted section that is wider at the top and narrower at the bottom.

[0022] As an improvement, the stacking holes of the stacking support legs have a narrowed section that is smaller at the top and larger at the bottom.

[0023] The beneficial effects of the pallet with a fence of this utility model are: the fence can switch between vertical unfolding and horizontal folding relative to the folding legs. When the fence is vertically unfolded, the stacking holes of the stacking legs of the upper pallet fit over the upper end of the fence of the lower pallet to achieve unfolded stacking; when the fence is horizontally folded, the stacking holes of the stacking legs of the upper pallet fit over the upper end of the folding legs of the lower pallet to achieve folded stacking; unfolded stacking and folded stacking are achieved by changing the position of the fence.

[0045] This utility model relates to a pallet with a fence. The fence can switch between being vertically unfolded and horizontally folded relative to the folding legs. When the fence is vertically unfolded, the stacking holes of the stacking legs of the upper pallet fit over the upper end of the fence of the lower pallet, achieving unfolded stacking. When the fence is horizontally folded, the stacking holes of the stacking legs of the upper pallet fit over the upper end of the folding legs of the lower pallet, achieving folded stacking. The unfolded stacking and folded stacking are achieved by changing the position of the fence.

[0046] Example 1

[0047] See Figures 1 to 7 The first embodiment of this utility model provides a foldable and unfoldable pallet with a guardrail, which includes:

[0048] Support plate 1;

[0049] Stacking support 2 is located below support plate 1;

[0050] Folding support leg 3 is located above support plate 1;

[0051] Fence 4;

[0052] Among them, the fence 4 and the folding legs 3 can switch between vertical unfolding and horizontal folding;

[0053] Among them, the lower end of the stacking support 2 is provided with stacking holes that are compatible with the folding support 3 and the upper end of the fence 4;

[0054] When the fence 4 is erected and unfolded, the stacking holes of the stacking legs of the upper pallet fit over the upper end of the fence 4 of the lower pallet, thus enabling unfolding and stacking.

[0055] When the fence 4 is folded flat, the stacking holes of the stacking feet of the upper pallet fit over the upper end of the folding feet 3 of the lower pallet, thus achieving folding stacking.

[0056] In this embodiment, the support plate 1 is a single piece, there are four stacking legs 2, four folding legs 3, and two fences 4 that are parallel when upright and unfolded. The stacking legs 2 and the support plate 1 are fixedly connected, and the folding legs 3 and the support plate 1 are also fixedly connected. The stacking legs 2, folding legs 3, and support plate 1 can be made of metal and fixed by welding.

[0057] In this embodiment, the support plate 1 is a rectangular plate. The two fences 4 are located on the two shorter widths of the rectangle, respectively.

[0058] In this embodiment, the four folding legs 3 are divided into two groups. The upper surface of the insertion hole 31 of one group of folding legs 3 is lower than the upper surface of the insertion hole 31 of the other group of folding legs 3. The two fences 4 are respectively connected to the two groups of folding legs 3.

[0059] In this embodiment, the fence 4 is assembled from multiple round tubes.

[0060] In this embodiment, the folding support leg 3 has an insertion hole 31. When unfolding and stacking, the lower end of the fence 4 is inserted into the insertion hole 31. When folding and stacking, the lower end of the fence 4 is removed from the insertion hole 31. When the lower end of the fence 4 is inserted into the insertion hole 31, the fence 4 is unfolded vertically, and the fence 4 can only be raised and lowered relative to the insertion hole 31. When folding and stacking is required, the fence 4 is lifted and then rotated to a flat folding position, at which time the fence 4 is lower than the folding support leg 3.

[0061] In this embodiment, the upper end of the folding support leg 3 is a stacking insertion part 30 adapted to the stacking hole. The stacking insertion part 30 has a notch 32 that communicates with the insertion hole 31. The notch 32 is located above the insertion hole 31. The folding support leg 3 and the fence 4 are connected by a pin 5. The fence 4 has an elongated groove 41 that moves relative to the pin 5. In other embodiments, the pin 5 can be replaced by a bolt, nut, or other structure. The notch 32 has a vertical groove for the fence 4 to be inserted and a horizontal groove for the fence 4 to be folded. This arrangement of the notch 32 allows the fence 4 to be rotated downwards to a flat folded position after it rises out of the insertion hole 31. When the fence 4 is folded flat, it is supported by the upper surface of the insertion hole 31.

[0062] In this embodiment, the folding support leg 3 has a pin hole 33, the fence 4 has a long groove 41, and the pin 5 is located in the pin hole 33 and the long groove 41.

[0063] In this embodiment, the notch 32 is a through groove that runs horizontally through the folding plane of the fence 4. The notch 32 runs horizontally through the fence, which facilitates processing and does not obstruct the horizontal position of the fence 4.

[0064] In this embodiment, the outer end of the pin 5 is a rivet head, and the inner end is bent. The outer end of the pin 5 is the opposite end of a pair of pins 5 on the same fence 4, and the inner end of the pin 5 is the opposite end of a pair of pins 5 on the same fence 4.

[0065] In this embodiment, the lower end of the fence 4 is a spherical surface 42. In other embodiments, the upper end of the socket 31 can also be designed as a constricted shape, wider at the top and narrower at the bottom. Both the spherical surface and the constricted shape serve to guide the fence 4, facilitating the insertion of the lower end of the fence 4 into the socket 31.

[0066] In this embodiment, the stacking hole of the stacking support 2 has a narrowed section that is smaller at the top and larger at the bottom.

[0067] In this embodiment, the depth of the insertion hole 31 of the folding support 3 is greater than the diameter of the spherical surface 42 of the fence 4, so that when the lower end of the fence 4 is located in the insertion hole 31, the fence 4 can only be raised and lowered, and cannot be displaced in other directions.

[0068] In this embodiment, during assembly, the four stacking legs 2 and the four folding legs 3 are fixed to the support plate 1 respectively. Then, the two fences 4 are inserted into the insertion holes 31 of the folding legs 3 respectively. The pin 5 is inserted from the outside into the long slot 41 of the fence 4 and the pin hole 33 of the folding legs 3. Finally, the inner end of the pin 5 is bent.

[0069] In this embodiment, the stacking support 2 is in the shape of a frustum, which is smaller at the top and larger at the bottom.

[0070] In this embodiment, the folding leg 3 is cylindrical.

[0071] In this embodiment, assuming the pallets are initially in a folded stacked state, when it is necessary to unfold the stack, each pallet is removed in turn, and the two railings 4 of each pallet are rotated to be approximately vertical, so that the lower ends of the two railings 4 of each pallet are inserted into the corresponding insertion holes 31 of the folding support legs 3. Since the lower end of the railing 4 is a spherical surface 42, it is relatively easy to align and insert. After insertion, the railing 4 can only be raised and lowered. At this time, the items are placed on the support plate 1, so that the stacking holes of the stacking support legs 2 of the upper pallet are aligned with the upper ends of the railings 4 of the lower pallet. The pallets are stacked in turn, and the structure after unfolding the stack is as follows. Figure 6 As shown. When folding and stacking are required, lift the upper pallet so that the stacking holes of the stacking legs 2 on the upper pallet move out of the upper end of the fence 4 on the lower pallet, remove the upper pallet from the lower pallet, and then lift the lower lower fence 4 (as shown). Figure 3As shown), because the fence 4 has a long slot 41, the fence 4 can rise when the pin 5 on the folding leg 3 is stationary, allowing the lower end of the fence 4 to move out of the insertion hole 31 of the folding leg 3. Then, the fence 4 is rotated toward another fence 4. After being rotated into place, the pin 5 is approximately at the lowest position in the long slot 41 of the fence 4. At this time, the same operation is performed on another fence 4 with a higher lower end (such as...). Figure 4 As shown), the final folded stacking structure is as follows: Figure 7 As shown. When the two fences 4 are erected and unfolded, their upper ends are basically level, while their lower ends are different in height, meaning that the two fences 4 have different heights, so that when they are folded flat, the two fences 4 are basically horizontal.

[0072] The beneficial effects of the pallet with railing in Embodiment 1 of this utility model are as follows: the railing 4 can switch between vertical unfolding and horizontal folding relative to the folding support 3. When the railing 4 is vertically unfolded, the stacking hole of the stacking support of the upper pallet fits onto the upper end of the railing 4 of the lower pallet, realizing unfolding and stacking; when the railing 4 is horizontally folded, the stacking hole of the stacking support of the upper pallet fits onto the upper end of the folding support 3 of the lower pallet, realizing folding and stacking; unfolding and folding stacking are achieved by changing the position of the railing 4; the number of parts is small, only five types are required; during the folding and unfolding process, only the railing 4 needs to be operated, and there is no need to operate the pin 5, making the operation simple and convenient; the position can be reliably maintained whether folding or unfolding; after the railing 4 is vertically unfolded, the rotation of the railing 4 is restricted by the side wall of the insertion hole 31 of the folding support 3, and the force is completely or basically borne by the side wall of the insertion hole 31, while the pin 5 is completely or basically unloaded. Compared with the method of relying on the pin 5 for force, the structural strength is better.

[0073] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
