Description

Technical Field

[0001] The utility model relates to the technical field of footings, and more particularly to a pallet footing. Background Art

[0002] Currently, most of the existing standard iron pallets use the pallet feet of plastic pallets or wooden pallets, using thin iron plates to make a square or rectangular foot. They are large in size, with a large distance between the upper and lower pallets, and occupy more space. At the same time, it is difficult to ensure the upper and lower alignment when the upper and lower pallets are stacked. Especially when used in AGV carts, auxiliary alignment devices must be used to barely meet the basic alignment requirements. It is difficult to achieve accurate upper and lower positioning and alignment. In addition, the load-bearing weight is limited. When it is necessary to carry more than ten tons of items, the standard iron pallets on the market can no longer carry them, and special steel frames need to be used.

[0003] Iron stacking transport racks have similar foot cups and support rods. Generally, the foot cups are placed at the bottom to serve as the support. When stacking, the foot cups fall on the top of the support legs to limit the stacking and prevent slipping. However, this structure has the following disadvantages:

[0004] (1) The foot cup does not have high requirements for size, shape and positioning accuracy. A large foot cup is convenient for stacking up and down. Since the foot cup is at the bottom and the support rod is at the top, the foot cup is large and exceeds the outer frame size of the transport rack, resulting in a waste of volume and area;

[0005] (2) When the foot cup falls to the ground, the edges can easily damage the ground;

[0006] (3) The combined height of the foot cup and the support rod must be very high to form stacking space, so an empty iron transport rack requires more stacking space than a pallet;

[0007] (4) The height of the foot cup and the support rod is very high, making it almost impossible to keep the upper and lower parts in a vertical line. If the bottom part deviates from the vertical line a little, the upper part will deviate a lot. If the foot cup of the iron transport rack is placed on the top, it will cause the stacking to be uneven, resulting in stacking risks. At the same time, the support rod falls to the ground, and the contact area with the ground is small, which is more unstable and leads to greater risks. This is because this structure is also unsafe and unusable.

[0008] (5) The foot cup and the support rod are welded together, so the height is fixed and the stacking height cannot be adjusted. If the height of the stored items changes, a new iron stacking transport rack can only be made. This is a huge waste of resources.

[0009] Therefore, it is necessary to design a new type of pallet foot to meet the above-mentioned heavy weight bearing capacity, while also being able to meet the pallet stacking and positioning accuracy requirements of the pallet application, as well as to overcome the disadvantages of iron stacking transport racks such as ground protection, volume space saving, upper and lower misalignment, and difficult height adjustment.

[0011] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0012] A pallet foot comprises a guide part and a support part located below the guide part, wherein the top of the guide part is provided with an opening, an inverted cone-shaped insertion space is provided in the guide part, a cavity is provided in the support part, and the cavity is communicated with the insertion space.

[0013] Furthermore, a ground protection structure is arranged at the bottom of the support part.

[0014] Furthermore, the guide portion is in the shape of an inverted square cone, a polygonal cone or an inverted circular cone, and the inner extending space thereof is also in the shape of an inverted square cone, a polygonal cone or an inverted circular cone.

[0015] Furthermore, the support portion is in the shape of a circular tube, a square tube, a rectangular tube or a polygonal tube.

[0016] Furthermore, auxiliary structures are provided on the support part and the guide part, and the auxiliary structures are a plurality of auxiliary holes.

[0017] Furthermore, an extension portion is provided on the top of the guide portion, and the extension portion extends upward along the upper side of the guide portion.

[0018] Furthermore, the guide portion and the support portion are connected by welding or are integrally formed.

[0019] Furthermore, the upper dimension of the guide portion is ≤ the outer dimension of the support portion×2.

[0020] Furthermore, the outer dimension of the support portion is ≤ the lower dimension of the guide portion ≤ the outer dimension of the support portion + 5 mm.

[0021] Furthermore, the pallet foot height is ≤250mm.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The pallet feet of the utility model are provided with guiding parts and supporting parts, and the guiding parts are used to cooperate and connect with the pallet body to carry out load transfer and sharing, and the supporting parts are used to carry the overall support of the pallet, and openings, insertion spaces and cavities are provided at the same time, so that when the pallets are stacked, the feet of the upper pallet can be guided and inserted through the openings and insertion spaces and finally enter the cavity, so that when the pallets are stacked, the feet of the pallets can be inserted into the insertion spaces and cavities of the lower pallets one by one, so that there is no large space between the upper and lower pallets when stacked, and space is effectively saved.

[0024] Furthermore, by providing a ground protection structure, an auxiliary structure and an extension part, the function of the pallet foot and the connection effect between the pallet foot and the pallet body are improved;

[0025] At the same time, by controlling the height and size of the guide part and the support part, it is possible to control the manufacturing accuracy of the pallet feet and use an integrated molding process. The processing accuracy of the pallet feet is improved, so the vertical accuracy and positioning accuracy of the pallet can be controlled well. By inserting a tubular plug rod into the support part of the pallet feet and cooperating with the guide inverted cone, the stacking height of the stacking rack can be well extended. Due to the high vertical accuracy, the stacking is accurately positioned up and down. Since the tubular plug rod is an assembleable part, the stacking height can also be adjusted.
