Technical Field
[0001] This utility model belongs to the field of pallet technology and relates to a pallet. Background Technology
[0002] A pallet is a horizontal board used to gather and stack goods for easy loading, unloading and handling. The minimum height of a pallet can accommodate the handling requirements of pallet trucks, forklifts or other applicable loading equipment, and it is especially suitable for heavy goods, concentrated loads or scenarios that require stacking.
[0003] Traditional pallets are generally made of wood, with the wood pieces fastened together with screws. This process consumes a large amount of timber, which is not in line with ecological development requirements. Gradually, most existing pallets are made of plastic. Specifically: 1. Plastic pallets are injection molded in one piece, but due to the complex structure of the pallet, injection molding is difficult, resulting in a low yield rate; 2. Plastic pallets are blow molded in one piece, but because the blow-up ratio of the pallet's support legs is greater than that of the panel, the wall thickness of the support legs is thinner than that of the panel after blow molding, leading to quality defects. Therefore, the existing plastic pallets suffer from inconvenient manufacturing and high production costs, which urgently need to be addressed. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a new type of pallet. The technical problem this invention aims to solve is how to address the inconvenience of manufacturing existing plastic pallets while ensuring the structural strength of the pallet.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A tray includes two trays having a plurality of first legs, characterized in that the first legs of the two trays are arranged one above the other, the first legs are cylindrical and have a locking seat and a plug on their side wall, the plug is columnar and has a protrusion protruding laterally at its head, the locking seat is cylindrical and has a locking slot on its side wall, and the plug on one tray can be inserted into the locking seat on the other tray, and the protrusion engages with the locking slot to form a vertical positioning.
[0007] The two pallets of this pallet can be manufactured separately and then reassembled. Furthermore, both pallets can share a single mold during production, thus solving the problem of inconvenient manufacturing of existing plastic pallets. Simultaneously, the columnar insertion post has a laterally protruding head, and the cylindrical locking seat has a locking slot on its side wall. The protrusion can engage with the slot to form a vertical positioning, allowing the insertion post to interlock with the locking seat vertically after insertion, thus preventing the insertion post from easily disengaging from the locking seat in the opposite direction of insertion and resisting certain lateral or torsional forces. This improves the firmness of the connection between the insertion post and the locking seat, thereby enhancing the stability and reliability of the two pallets' locking and positioning, ensuring the structural strength of the connection between the two pallets, and ultimately guaranteeing the overall structural strength of the pallet.
[0008] In one type of pallet described above, a plurality of first legs on the pallet are arranged in a matrix. Each first leg is cylindrical in shape, and some or all of the first legs on the pallet have vertically arranged reinforcing partitions on their inner walls. The reinforcing partitions on two first legs arranged vertically opposite each other abut against each other. This design facilitates insertion by forklifts from four directions (front, back, left, and right) while simultaneously improving the structural strength of the pallet.
[0009] A tray includes a rectangular support panel and three parallel strip-shaped support bases below the rectangular support panel. The rectangular support panel has a plurality of second legs, and the strip-shaped support bases have a plurality of third legs. The second and third legs are arranged vertically opposite each other. Both the second and third legs are cylindrical, and each has a locking seat and a plug-in post on its sidewall. The plug-in post is columnar with a laterally protruding head. The locking seat is cylindrical with a locking slot on its sidewall. The plug-in posts on both the rectangular support panel and the strip-shaped support bases can be inserted into each other's locking seats, and the protrusion engages with the locking slot to form a vertical positioning.
[0010] The rectangular support panel and three strip support plates of this pallet can be manufactured separately and then assembled. Furthermore, by incorporating inserts within the mold, the rectangular support panel and strip support plates can share a single mold during production, thus solving the inconvenience of manufacturing existing plastic pallets. Additionally, the columnar insertion post has a laterally protruding head, and the cylindrical locking seat has a locking slot on its side wall. The protrusion can engage with the slot to form a vertical positioning, allowing the insertion post to interlock with the locking seat vertically after insertion, thus preventing the insertion post from easily disengaging from the locking seat in the opposite direction of insertion and resisting certain lateral or torsional forces. This improves the strength of the connection between the insertion post and the locking seat, ensuring the structural strength of the connection between the rectangular support panel and the three strip support plates, thereby guaranteeing the overall structural strength of the pallet.
[0011] In the above-mentioned tray, the edge of the bayonet is provided with a clamping strip block with a V-shaped cross-section, and the clamping strip block can form lateral positioning for the protrusion. The firmness of the connection between the insertion post and the clamping seat can be further improved, and at the same time, the clamping and unclamping of the insertion post and the clamping seat are facilitated, thereby further improving the stability and reliability of the buckling positioning of the tray.
[0012] In the above-mentioned tray, the top edge of the clamping seat is provided with two guide side plates disposed oppositely in the vertical direction, and the guide side plates protrude upward from the first support leg, the second support leg or the third support leg. On the one hand, the guide side plates can play the role of guiding and limiting the movement of the insertion post during clamping, so that the insertion of the insertion post and the protrusion is smoother. On the other hand, they can also play a role in supporting the insertion post, preventing the insertion post from tilting to one side and disengaging from the clamping by itself after insertion, improving the firmness of the connection between the insertion post and the protrusion, and increasing the structural strength.
[0013] In the above-mentioned tray, one of the supporting plates is in a shape of a Chinese character "tian", which can meet different use requirements of users.
[0014] Compared with the prior art, the advantages of the present tray are: the two supporting plates (or the rectangular supporting panel and three strip-shaped bottom supporting plates) of the tray can be manufactured separately and then assembled, and in addition, the two supporting plates (or the rectangular supporting panel and three strip-shaped bottom supporting plates, which require inserts to be arranged in the mold) can share a pair of molds during production, thereby solving the problem of inconvenient manufacturing of existing plastic trays. Meanwhile, the head of the columnar insertion post is provided with a laterally protruding protrusion, the side wall of the cylindrical clamping seat is provided with a bayonet, and the protrusion can be clamped into the bayonet to form vertical positioning, so that when the insertion post is inserted into the clamping seat, it can mutually engage with the clamping seat in the vertical direction to form a mechanical interlock, thereby preventing the insertion post from easily disengaging from the clamping seat in the direction opposite to the insertion direction, and can resist certain lateral force or torsion force, which in turn can improve the firmness of the connection between the insertion post and the clamping seat, thereby improving the stability and reliability of the buckling positioning of the two supporting plates (or the rectangular supporting panel and three strip-shaped bottom supporting plates), so as to ensure the structural strength at the connection of the two supporting plates of the tray, and further ensure the structural strength of the tray.

Detailed Implementation
[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0026] Example 1
[0027] A tray, reference Figure 1-5 The device comprises two trays 1 each having a plurality of first legs 1a. The first legs 1a of the two trays 1 are arranged vertically opposite each other. Each first leg 1a is cylindrical and has a locking seat 3 and a plug-in post 2 on its side wall. The plug-in post 2 is columnar with a laterally protruding protrusion 2a at its head. The locking seat 3 is cylindrical with a locking slot 3a on its side wall. Each plug-in post 2 on one tray 1 can be inserted into the locking seat 3 on the other tray 1, and the protrusion 2a engages with the locking slot 3a to form a vertical positioning. This ensures that the first legs 1a of the two trays 1, arranged vertically opposite each other, are mutually engaged and positioned.
[0028] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 Specifically, the first legs 1a on the pallet 1 are arranged in a matrix. The first legs 1a are in the shape of a square tube. Some or all of the first legs 1a on the pallet 1 have vertically arranged reinforcing partitions 4 on their inner walls, and the reinforcing partitions 4 on two first legs 1a arranged vertically abut against each other.
[0029] Reference Figure 2, Figure 3 and Figure 4 , further, the edge of said bayonet 3a is provided with a clamping strip 3b having a V-shaped cross section, and said clamping strip 3b can form lateral positioning for said protrusion 2a.
[0030] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , still further, the top edge of said clamping seat 3 is provided with two oppositely arranged guide side plates 3c along the vertical direction, and said guide side plates 3c protrude upward beyond said first leg 1a.
[0031] The two pallets 1 of the pallet can be manufactured separately and then assembled, thereby solving the problem of inconvenient manufacturing of existing plastic pallets. Meanwhile, the head of the cylindrical inserting post 2 is provided with a protrusion 2a protruding laterally, the side wall of the cylindrical clamping seat 3 is provided with a bayonet 3a, and said protrusion 2a can be clamped into said bayonet 3a to form vertical positioning, so that after the inserting post 2 is inserted into the clamping seat 3, it can be mutually engaged with the clamping seat 3 in the vertical direction to form a mechanical interlock, thereby preventing the inserting post 2 from easily disengaging from the clamping seat 3 in a direction opposite to the inserting direction, and can resist certain lateral force or torsion force, thereby improving the connection firmness between the inserting post 2 and the clamping seat 3, further improving the stability and reliability of the buckling positioning of the two pallets 1, thereby ensuring the structural strength of the connection between the two pallets of the pallet, and further ensuring the structural strength of the pallet.
[0032] In addition, the pallet is assembled by inserting and buckling a plurality of legs 1a of two pallets 1. Specifically, each of said legs 1a is provided with two inserts of different specifications, the inserts are divided into an inserting post 2 and a clamping seat 3 in inserting fit with the inserting post 2, after one of the pallets 1 is turned 180°, the legs 1a of the two pallets 1 arranged opposite to each other in up-down direction are positioned by inserting and buckling through said inserting post 2 and clamping seat 3. Since the two pallets 1 have the same shape and size, they can be injection-molded by the same mold. In addition, when one pallet is damaged, it can be replaced separately, and the undamaged pallet can continue to be assembled with a new pallet for use, prolonging the service life.
[0033] Embodiment II
[0034] The structure and principle of this embodiment are substantially the same as those of Embodiment I, and the difference is: referring to Figure 6 , one of said pallets 1 has a "field" shape.
[0035] Embodiment III
[0036] The structure and principle of this embodiment are substantially the same as those of Embodiment I, and the difference is: a pallet, referring to Figure 7-9The device includes a rectangular support panel 5 and three parallel strip support plates 6 arranged below the rectangular support panel 5. The rectangular support panel 5 has several second legs 5a, and the strip support plates 6 have several third legs 6a. The second legs 5a and the third legs 6a are arranged vertically opposite each other. Both the second legs 5a and the third legs 6a are cylindrical, and both have a locking seat 3 and a plug-in post 2 on their side walls. The plug-in post 2 is columnar, and its head has a protrusion 2a that protrudes laterally. The locking seat 3 is cylindrical, and its side wall has a locking slot 3a. The plug-in posts 2 on the rectangular support panel 5 and the strip support plates 6 can be inserted into the locking seat 3 of each other, and the protrusion 2a is locked into the locking slot 3a to form a vertical positioning.
[0037] Reference Figure 7 , Figure 8 and Figure 9 Furthermore, the top edge of the protrusion 3 has two guide side plates 3b arranged vertically opposite each other, and the guide side plates 3b extend upwards from the second leg 5a or the third leg 6a.
[0038] The rectangular support panel 5 and the three strip support bottom plates 6 of this pallet can be manufactured separately and then assembled. Furthermore, by setting inserts within the mold, the rectangular support panel 5 and the strip support bottom plates 6 can share a single mold during production, thus solving the problem of inconvenient manufacturing of existing plastic pallets. Simultaneously, the columnar insertion post 2 has a laterally protruding protrusion 2a at its head, and the cylindrical locking seat 3 has a locking slot 3a on its side wall. The protrusion 2a can engage with the locking slot 3a to form a vertical positioning, allowing the insertion post 2 to interlock with the locking seat in the vertical direction after insertion into the locking seat 3, thus preventing the insertion post 2 from easily disengaging from the locking seat 3 in the opposite direction of insertion and resisting certain lateral or torsional forces. This improves the firmness of the connection between the insertion post 2 and the locking seat 3, thereby ensuring the structural strength of the connection between the rectangular support panel and the three strip support bottom plates of this pallet, and ultimately ensuring the structural strength of the pallet.
