Description

Technical Field

[0001] The utility model relates to the field of logistics pallets, and particularly to a foldable logistics pallet. Background Technique

[0002] Logistics refers to the industry that specializes in the transportation, storage, loading and unloading, handling, packaging, distribution processing, distribution, and information processing of goods and services. It is an important part of the social economy and plays a crucial role in the development of the entire social economy. The logistics industry covers all activities from raw material procurement, commodity production to product distribution and delivery to the final consumer. It includes multiple links such as transportation, warehousing, packaging, loading and unloading, distribution, and information processing, and is an important part of the modern economic system.

[0003] A pallet refers to a horizontal platform device used for containerizing, stacking, handling, and transporting goods and products placed as unit loads. It has now been widely used in all walks of life, especially in the fields of transportation, warehousing, and circulation. The pallet is considered one of the two key innovations in the logistics industry in the 20th century. Pallets are usually used in conjunction with forklifts, or hand-pushed flatbed carts, or hydraulic trucks, which can greatly improve logistics efficiency and reduce cargo damage and errors, playing an invaluable role in logistics. In the prior art, pallets often cannot be applied to goods of different sizes, and there are problems such as the logistics pallet being unable to carry large goods or the goods being too small while the logistics pallet is too large and occupying space. For example, the Chinese patent with the publication number CN219822066U discloses a foldable logistics pallet, which realizes pallet folding by setting rod grooves, extension rods, etc., saving warehouse space, but the folding operation of this device is complex, and it cannot change the pallet size according to the goods.

[0004] The foldable logistics pallet is an innovative logistics equipment designed to improve the efficiency of warehousing and transportation, while reducing space occupation and costs. The foldable logistics pallet is an innovative logistics auxiliary tool that breaks through the limitations of traditional pallets in design. It not only has the basic functions of carrying and transporting goods, but also introduces a foldable structure, greatly improving the space utilization efficiency during storage and transportation.

[0005] Therefore, providing a foldable logistics pallet with simple folding operation and adaptable to goods of different sizes for cargo handling is the goal that those skilled in the art are committed to researching. Content of the Utility Model

[0006] The purpose of the utility model is to provide a foldable logistics pallet to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A foldable logistics tray, comprising a first tray and a second tray, the first tray and the second tray are hinged, the first tray is telescopically connected with a first auxiliary tray, the second tray is telescopically connected with a second auxiliary tray, and support columns are fixedly connected to the bottoms of the first tray and the second tray.

[0009] Further, in a foldable logistics tray, the first tray and the second tray are both provided with cavities for receiving the corresponding first auxiliary tray and second auxiliary tray.

[0010] Further, a plurality of hinges are provided between the first tray and the second tray. A plurality of bolts are provided at the tops of the hinges, and the bolts penetrate through the hinges.

[0011] Further, handles are embedded in the middle parts of the first auxiliary tray and the second auxiliary tray on the sides away from the hinges.

[0012] When the articles transported by the present utility model are smaller than the plane, the articles are placed on the plane formed by the first tray and the second tray for logistics transportation. When the articles transported are larger than the plane, the first auxiliary tray and the second auxiliary tray are respectively moved out from the cavities of the first tray and the second tray, so as to expand the plane area. The articles are placed on the plane formed by the first tray, the second tray, the first auxiliary tray and the second auxiliary tray for logistics transportation; hinges are provided between the first tray and the second tray, and the hinges control the folding of the first tray and the second tray. Before folding, the tops of the hinges are on the same horizontal line as the first tray and the second tray. After folding, the first tray and the second tray are in contact or there are gaps; the first auxiliary tray is pulled or pushed out from the first tray or received, and the second auxiliary tray is pulled out from the second tray or received by pulling the handles.

[0013] Further, a sliding assembly is provided between the first tray and the first auxiliary tray.

[0014] Furthermore, the sliding assembly includes a groove provided on the inner wall of the top of the first tray and a protrusion provided on the top surface of the first auxiliary tray. The groove is adapted to the protrusion, and the first tray and the first auxiliary tray are slidably connected through the groove and the protrusion.

[0015] When the present utility model uses the handle to move the first auxiliary tray, the protrusion on the top surface of the first auxiliary tray moves along the groove on the inner wall of the top of the first tray. Therefore, the movement track of the first auxiliary tray can be better defined, and the deviation of the first auxiliary tray can be prevented; the same sliding assembly is also provided between the second tray and the second auxiliary tray.

[0016] Further, a first locking assembly is provided between the first tray and the first auxiliary tray.

[0017] Furthermore, the locking assembly includes a locking groove provided at the bottom of the first tray, a locking mouth provided at the first sub-tray, a spring, an insertion rod and a limit block.

The spring is built into the locking mouth, the bottom end of the spring is fixedly connected to the insertion rod, the limit block is threadedly connected to the locking mouth, and the insertion rod passes through the limit block.

[0018] The top end of the insertion rod of the utility model contacts the inner side of the bottom of the first pallet. When the insertion rod moves with the first sub-pallet, it moves along the surface and slope of the first pallet into the locking hole. During this process, the spring continuously extends, and the insertion rod is embedded in the locking hole, thereby locking the first sub-pallet with the first pallet. The limit block limits the position of the insertion rod, preventing the insertion rod from escaping from the locking groove. The first pallet can be provided with a plurality of locking holes arranged at intervals along the movement trajectory of the first sub-pallet to achieve locking between the first sub-pallet and the first pallet at different distances. Similarly, the second pallet is also provided with the same locking assembly.

[0041] In the specific implementation process, when the transported item is smaller than the plane, the item is placed on the plane formed by the first tray 1 and the second tray 2 for logistics transportation. When the transported item is larger than this plane, the first auxiliary tray 3 and the second auxiliary tray 4 are respectively moved out from the cavities of the first tray 1 and the second tray 2, thereby expanding the plane area. The item is placed on the plane formed by the first tray 1, the second tray 2, the first auxiliary tray 3 and the second auxiliary tray 4 for logistics transportation; A hinge 6 is provided between the first tray 1 and the second tray 2, and the hinge 6 controls the folding of the first tray 1 and the second tray 2. Before folding, the top of the hinge 6 is on the same horizontal line as the first tray 1 and the second tray 2. After folding, the first tray 1 and the second tray 2 are completely fitted; The first auxiliary tray 3 and the second auxiliary tray 4 can be moved by pushing and pulling the handle 5.

[0042] Embodiment 2

[0043] As Figure 1 shown, this embodiment provides a foldable logistics tray. The difference from Embodiment 1 is that a sliding component is provided between the first tray 1 and the first auxiliary tray 3; It includes a groove provided on the inner wall of the top of the first tray 1 and a protrusion provided on the top surface of the first auxiliary tray 3. The above groove and the protrusion are adapted, and the first tray 1 and the first auxiliary tray 3 are slidably connected through the groove and the protrusion.

The cushion plates are used to ensure the flatness of the tray and prevent the goods from shaking and falling during the transportation of the goods.

[0045] In the specific implementation process, when using the handle 5 to move the first auxiliary tray 3, the protrusion on the top surface of the first auxiliary tray 3 moves along the groove on the inner wall of the top of the first tray 1. Therefore, the movement trajectory of the first auxiliary tray can be better defined, and the deviation of the first auxiliary tray 3 can be prevented; The same sliding component is also provided between the second tray 2 and the second auxiliary tray 4.

[0046] Embodiment 3

[0047] As Figure 2 shown, this embodiment provides a foldable logistics tray. The difference from Embodiment 1 is that a locking component one is provided between the first tray 1 and the first auxiliary tray 3; It includes a locking groove 14 provided at the bottom of the first tray, a locking port 15 provided on the first auxiliary tray, a spring 16, a plug rod 18 and a limiting block 17. The above locking groove 14 is provided with a slope. The above spring 16 is built in the above locking port 15. The bottom end of the above spring 16 is fixedly connected to the above plug rod 18. The above limiting block 17 is threadedly connected to the above locking port 15, and the above plug rod 18 passes through the above limiting block 17.

[0048] As an alternative, the above-mentioned locking groove 14 is designed with openings to improve the working stability of the insertion rod 18.

[0049] As an alternative, the structure of the above-mentioned insertion rod 18 can be a combination of a cylinder and a hemisphere, a sphere, or a cylinder, to improve the smoothness of the operation of the insertion rod 18.

[0050] In the specific implementation process, when the insertion rod 18 is not inserted into the locking groove, the insertion rod 18 is squeezed by the inner side of the bottom of the first tray 1, causing the spring 16 to contract and extend into the locking opening 15. The top of the insertion rod 18 is tangent to the inner side of the bottom of the first tray 1. When the insertion rod 18 moves to the locking groove 14 along with the first sub-tray 3, the spring 16 expands, driving the insertion rod 18 to insert into the locking opening 15. The limiting block 17 fixes the position of the insertion rod 18 and will not tilt due to the push or pull of external forces. In addition, a slope is provided around the locking groove 14 at the inner bottom of the first tray 1, and the insertion rod 18 slides along the slope to the lowest or highest end of the locking groove 14, thereby completing the fixation and movement of the first sub-tray 3. The same locking assembly one is also provided between the second tray 2 and the second sub-tray 4.

[0053] As an alternative, the above-mentioned locking assembly two can be provided at the bottom or side of the above-mentioned first tray 1 and the second tray 2.

[0054] In the specific implementation process, after the first tray 1 and the second tray 2 are unfolded through the hinge 6, the locking member 10 on the first fixing plate 9 drives the fixing ring 11 to be snap-connected with the fastening member 12 on the second fixing plate 13, thereby fixing the positions of the first tray 1 and the second tray 2. When the first tray 1 and the second tray are folded through the hinge 6, first move the fixing ring 11 out of the fastening member 12 and return the locking member 10 to its original position, thereby canceling the fixation of the first tray 1 and the second tray 2.

[0055] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the described embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the relevant art.
