Description

Technical Field

[0001] This application relates to the field of pallets, and more particularly to a pallet box base. Background Technology

[0002] The manufacturing processes for pallets include injection molding and blow molding.

[0003] Injection molding uses polyethylene or polypropylene plastic granules as raw materials. After mixing, the mixture is injected into an injection molding machine for high-temperature plasticization, and then sprayed into a custom mold for cooling and shaping. Blow molding uses high-molecular-weight high-density polyethylene and other raw materials. The mixture is heated and plasticized in an extruder to form a tubular preform, which is then placed in a mold and blown in with compressed air to form the final shape.

[0004] Injection-molded pallets have a low load-bearing capacity, are prone to deformation when overloaded, and may soften under extreme temperatures. Blow-molded pallets have superior performance under extreme temperatures, but they have a hollow double-layer structure and cannot be reinforced with steel pipes. The hollow structure has low bending strength and is prone to deformation under extreme loads.

[0005] Therefore, how to design a base for inserting steel pipes into a pallet formed by blow molding has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This application provides a base for a panel box to at least solve the above-mentioned technical problems existing in the prior art.

[0007] A base for a pallet box is provided, including a hollow pallet. The top wall of the pallet has several first grooves recessed into one side of the inner cavity to form a first guard edge. The bottom wall of the pallet has several second grooves recessed into one side of the inner cavity to form a second guard edge. The first grooves and second grooves are arranged along a first direction. The first guard edge and second guard edge form a placement cavity in the inner cavity. A steel pipe is inserted into the placement cavity. The outer wall of the steel pipe abuts against the inner wall of the placement cavity. The base also includes a sealing end cap to seal the steel pipe in the placement cavity.

[0008] In one embodiment, the top wall of the tray is provided with a downwardly recessed retaining groove.

[0009] In one embodiment, a blow-molded block is provided at the location of the enclosure groove along the first direction to pre-seal the placement cavity.

[0010] In one embodiment, the sealing end cap is provided with a plug-in end and a clearance end. The plug-in end is inserted into the placement cavity, and the outer wall of the plug-in end abuts against the inner wall of the placement cavity. The clearance end is located in the enclosure groove and is provided with a clearance opening.

[0011] In one embodiment, the cross-section of the first groove or the second groove is L-shaped and the other is U-shaped.

[0012] In one embodiment, the bottom wall of the tray is recessed to the side away from the inner cavity to form a plurality of support legs. The support legs are provided with insertion parts and also include a bottom support. The top wall of the bottom support is provided with a support groove. The bottom support is arranged along the second direction. The insertion parts of the support legs are inserted into the support groove. The support legs and the bottom support are detachably connected by positioning members.

[0013] In one embodiment, the positioning element includes a positioning bolt and a positioning nut, the positioning bolt extending through the base into the insertion portion and being threadedly connected to the positioning nut.

[0014] In one embodiment, the plug portion is provided with a downwardly recessed drainage port, and the base is provided with a drainage hole. The drainage hole and the drainage port on the plug portion are paired one by one to drain water accumulated in the inner cavity of the support leg.

[0015] In one embodiment, the top wall of the base is provided with an upwardly extending support portion, and a support groove is provided on the top wall of the support portion and is recessed downward.

[0016] In one embodiment, a first insertion area is provided between two adjacent support legs, and a second insertion area is provided between two adjacent support parts, with the first insertion area and the second insertion area corresponding to form an insertion chamber.

[0017] Compared with the prior art, the panel box base proposed in this application has the following advantages:

[0018] This application provides a first and a second retaining edge recessed into one side of the bottom and top walls of a hollow pallet, respectively. The first and second retaining edges form a placement cavity for placing steel pipes. At this time, the outer wall of the steel pipe abuts against the first and second retaining edges, thereby restricting the movement of the steel pipe in the inner cavity of the hollow pallet and improving the stability of the steel pipe in the inner cavity. The steel pipe is arranged along a first direction, thereby strengthening the bending resistance of the hollow pallet in the first direction and improving the load-bearing capacity of the pallet under extreme environments.

[0037] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] The base of the enclosure box prepared in this application is an improvement on the structure of the base based on the traditional blow molding process, so that the base can facilitate the installation of steel pipe 2, improve the bending resistance of the base, and enhance the support effect of the base.

[0039] In this embodiment, as Figure 1 and Figure 3 As shown, the base of the enclosure box includes a blow-molded tray 1, wherein the tray 1 has a hollow structure and an inner cavity 10 is formed inside.

[0040] Normally, the strength of the pallet 1 is improved by forming reinforcing ribs inside the inner cavity 10. However, the strength of the pallet 1 is affected by its own material, making it difficult for the strength of the pallet 1 to meet the pre-design requirements and failing to meet the bending resistance of the pallet 1. The formation of reinforcing ribs in the inner cavity 10 of the pallet 1 will increase the production material and increase the production cost, making it difficult to achieve the purpose of cost saving.

[0041] Therefore, this application forms a fixing mechanism for placing the steel pipe 2 based on the hollow structure of the pallet 1, thereby solving the problems of the bending resistance of the pallet 1 and the production cost of the pallet 1.

[0042] Before introducing the structure of the pallet box, let's redefine its orientation for better understanding. With the pallet box placed on the ground, the side closer to the ground is the lower side, and the side farther from the ground is the upper side. The length of the pallet box is defined as the first direction X, and the width of the pallet box is defined as the second direction Y.

[0043] Specifically, such as Figure 3 As shown, the hollow structure of the pallet 1 is composed of an inner cavity 10. Although the inner cavity 10 can be used to place the steel pipe 2, it cannot form a structure to effectively fix the steel pipe 2, causing the steel pipe 2 to sway in the inner cavity 10.

[0044] Therefore, such as Figure 3As shown, the top wall of the pallet 1 is provided with several first grooves 11 recessed into one side of the inner cavity 10, and the bottom wall of the pallet 1 is provided with several second grooves 13 recessed into one side of the inner cavity 10. The first grooves 11 and the second grooves 13 are both arranged along the first direction X. The first grooves 11 form a first baffle 12 in the inner cavity 10, and the second grooves 13 form a second baffle 14 in the inner cavity 10. At this time, the first baffle 12 and the second baffle 14 form a placement cavity 15 for the steel pipe 2 to be inserted in the first direction X. When the steel pipe 2 is installed inside the placement cavity 15, the outer wall of the steel pipe 2 abuts against the first baffle 12 and the second baffle 14, thereby improving the stability of the steel pipe 2.

[0045] Furthermore, in this application, the cross-section of the first groove 11 is L-shaped and the cross-section of the second groove 13 is U-shaped. The advantage of this design is that the second flange 14 formed by the second groove 13 can support the steel pipe 2. At the same time, the sidewall of the second flange 14 can restrict the steel pipe 2 from swaying along the second direction Y, thereby improving the stability of the steel pipe 2.

[0046] Since the first groove 11 has an L-shaped cross section and is located above the steel pipe 2, the first retaining edge 12 abuts against the steel pipe 2, which can restrict the steel pipe 2 from sliding up and down, and further improve the stability of the steel pipe 2.

[0047] Since the pallet 1 of this application is manufactured by a blow molding process, the mold for forming the pallet 1 is provided with inserts for forming the first groove 11 and the second groove 13, wherein, as Figure 2 As shown, a blow molding block 4 is also provided at the first direction X port position of the placement cavity 15. The blow molding block 4 is used to pre-seal the end wall of the placement cavity 15 so as to realize the blow molding of the tray 1.

[0048] During the process of placing the steel pipe 2 into the placement cavity 15, the blow molding block 4 needs to be manually cut off to expose the placement cavity 15. At this time, the steel pipe 2 is then inserted into the placement cavity 15.

[0049] In order to limit the movement of the steel pipe 2 inside the placement cavity 15 along the first direction X, in this embodiment, as follows: Figure 4 As shown, it also includes a sealing end cap 3, wherein the sealing end cap 3 is inserted into the placement cavity 15, so that the end wall of the steel pipe 2 abuts against the sealing end cap 3, thereby restricting the steel pipe 2 from moving out of the placement cavity 15.

[0050] Since the base of this application is mainly used for the enclosure box, in order to realize the installation of the side panels of the enclosure box, in this embodiment, as follows: Figure 1 and Figure 5 As shown, the bottom wall of the pallet 1 is provided with a downwardly recessed enclosure groove 16, wherein the enclosure groove 16 is located at the outer edge of the pallet 1 and is used for the insertion of the side plate, thereby forming the side wall of the enclosure box.

[0051] It is worth noting here that, as Figure 4 As shown, the sealing end cap 3 includes an insertion end 31 and a clearance end 32. The insertion end 31 of the sealing end cap 3 is inserted into the placement cavity 15, and the outer wall of the insertion end 31 abuts against the inner wall of the placement cavity 15 to seal the placement cavity 15. The clearance end 32 is disposed in the enclosure groove 16.

[0052] To reduce interference from the clearance end 32 on the installation of the side panels of the enclosure box, in this embodiment, as follows: Figure 4 As shown, the clearance end 32 is provided with a clearance opening 321. At this time, the side panel of the enclosure box is inserted into the clearance opening 321, reducing the impact of the clearance end 32 on the installation of the side panel.

[0053] Specifically, in this embodiment, the top wall of the tray 1 is recessed downward to form a number of support legs 17. The number of support legs 17 is nine, forming a three-row, three-column distribution, which is the nine-legged tray in the prior art.

[0054] In this embodiment, as Figure 5 As shown, four steel pipes 2 are provided and are arranged along the first direction X, which enhances the bending resistance of the pallet 1 in the first direction X. In order to improve the bending resistance of the pallet 1 in the second direction Y, three sets of bottom supports 5 are also provided along the second direction Y. The bottom supports 5 are provided with downwardly recessed support grooves 51. Each bottom support 5 has three support grooves 51. The arrangement of the bottom supports 5 improves the bending resistance of the pallet 1 in the second direction Y.

[0055] With the above configuration, the base 5 and the pallet 1 form the base of the enclosure box. During use, the support leg 17 of the pallet 1 needs to be placed into the support groove 51 of the corresponding base 5.

[0056] To secure the tray 1 to the base 5, such as Figure 6 As shown, it also includes a positioning component 6, one end of which is connected to the base support 5, and the other end of which is connected to the support leg 17, thereby fixing the base support 5 and the support plate 1.

[0057] Furthermore, such as Figure 7 As shown, the positioning component 6 includes a positioning bolt 61 and a positioning nut 62. The positioning bolt 61 extends through the base 5 into the interior of the support leg 17, and the positioning nut 62 is located in the support leg 17 and is threadedly connected to the positioning bolt 61, thereby fixing the base 5 to the support plate 1.

[0058] In this embodiment, the top wall of the base 5 is provided with an upwardly extending support portion 50, wherein a support groove 51 is provided on the top wall of the support portion 50, a second insertion area 182 is formed between two adjacent support portions 50, and a first insertion area 181 is formed between two support legs 17. When the support legs 17 on the pallet 1 are installed inside the support groove 51, the first insertion area 181 and the second insertion area 182 form an insertion chamber 18, which is used by a forklift to lift the base of the pallet box and realize the transportation of the base of the pallet box.

[0059] Furthermore, the support leg 17 is provided with a plug-in part 171. When the tray 1 is installed on the base 5, the plug-in part 171 is plugged into the support groove 51, thereby realizing the installation of the tray 1 and the base 5.

[0060] The bottom wall of the plug part 171 is provided with a downward recessed drainage port 172 forming a perforation. The bottom support 5 is provided with a drain hole 52 aligned with the drainage port 172. When there is liquid on the support plate 1, the liquid converges into the support leg 17 of the support plate 1 and is finally discharged from the base of the enclosure box through the drainage port 172 and the drain hole 52.

[0061] The base 5 is made using a blow molding process, and the base 5 also contains a steel pipe 2 extending along the second direction Y.
