Description

Plastic pallet reinforcement structure

The present invention relates to a plastic pallet having a reinforcing structure at a central position and a side opening of the plastic pallet, and the four corner ends of the plastic pallet have a positioning structure, and the reinforcing structure and the positioning structure are integrally formed with the plastic pallet during manufacture. forming.

The conventional plastic pallet has a bearing surface on which the supply is stacked, and a supporting surface opposite to the bearing surface. The supporting surface and the bearing surface are respectively formed by a plurality of ribs intersecting each other, and the bearing surface and the supporting surface are disposed between the supporting surface and the supporting surface. There are a plurality of angular end support columns at the corner ends, a plurality of edge support columns at the edges, and a central central support column, and each of the side support columns and the adjacent corner end support columns are respectively provided with an opening, the opening It is used for the forklift of the stacker to facilitate the displacement and stacking of the cargo.

The plastic pallet is usually formed by plastic injection molding to obtain better bearing capacity and structural strength. Among them, the plurality of corner end support columns, the plurality of plate side support columns, and the central support column are hollow columns. With the arrangement of the plurality of ribs and the plurality of openings, the plastic pallet can be lightened, thereby reducing the plastic material and reducing the production cost.

Although the multiple rib structure of the plastic pallet can make the bearing surface carry heavier goods, there are still many disadvantages in the use of the pallet. For example, the central supporting column located in the center of the pallet is relatively concentrated, which is easy to be generated due to poor rigidity. The deformation causes the central bearing capacity of the pallet to be insufficient and collapse. In addition, in the operation of the stacker to prepare the displacement pallet, the opening of the pallet is easily collided by the fork of the stacker, causing stress concentration and breakage at the opening position, so that the service life of the pallet is shortened.

In addition, because the bearing surface of the plastic pallet is relatively smooth, the pallet is When stacked on each other, there is often a problem that the pallets slide and fall correspondingly to each other, and it is difficult to store and store. Similarly, when the pallet carrier surface is stacked, the disadvantage that the goods are not stable and fixed is also generated.

In view of this, the creator has accumulated many years of research and practical experience in related fields, and created a plastic pallet reinforcement structure to improve the strength of the central support column and the opening structure of the conventional pallet, resulting in shortened service life of the pallet. And the lack of slides and slides when stacked on the stack.

The main purpose of this creation is to strengthen the inner frame and the reinforced outer frame with the reinforcing structure in the central support column of the plastic pallet, and to provide a reinforced structure and a step-like protruding flange at each opening position to improve the conventional plastic. After the pallet is used for a long time, the central position is easy to collapse, and the opening is easily damaged by the collision of the stacker fork.

In order to achieve the above object, the present invention is a plastic pallet reinforcement structure, the plastic pallet has a bearing surface and a supporting surface opposite to the bearing surface, the bearing surface and the supporting surface are respectively formed by a plurality of fixed ribs intersecting each other. Between the bearing surface and the supporting surface, a plurality of angular end supporting columns at the corner ends, a plurality of edge supporting columns at the edges, and a central supporting column at the center, each supporting edge and the adjacent corner end An opening for the fork of the stacker is respectively arranged between the support columns, wherein: The central support column is a hollow columnar body, and the top surface thereof has a plurality of reinforcing ribs obliquely staggered with the angle of the fixed ribs, the central support column is surrounded by a reinforcing inner frame, and the reinforcing inner frame is surrounded by reinforcing ribs. The bottom facing the support surface extends in a crisscross-shaped reinforcing rib, and the outer periphery of the reinforcing inner frame is provided with a reinforcing outer frame at an appropriate distance to strengthen the structural strength of the central supporting column.

The reinforcing outer frame is between the bearing surface and the supporting surface, and the reinforcing ribs with the cross-shaped interlacing in the inner frame of the reinforcing inner frame can effectively increase the structural strength of the central supporting column and improve the use of the central supporting column of the traditional pallet. It is easy to deform after a long time and causes the central collapse of the pallet.

The following further describes the implementation of each component: when implemented, at least one protruding bearing is provided on the top surface of each corner end support column. a top surface of the baffle, the bottom end of the corner support column is provided with a concave positioning groove relative to the baffle, the upper plastic pallet is stacked on the bearing surface of the lower plastic pallet, and the corner end support post of the lower plastic pallet The baffles are respectively positioned in the positioning slots of the support columns of the corner end of the upper plastic pallet, so that the plastic pallets are relatively stable and not easy to be dumped when stacked on each other. In addition, the baffles can also assist in cargo positioning or be placed at the bottom of the cargo. After the corresponding structure is engaged with the flap, the cargo can not be easily slipped off the bearing surface.

In implementation, each of the corner support columns has a second baffle on the top surface thereof, and the second baffles are respectively arranged in an L shape on the adjacent sides of the corner end support columns.

In implementation, an L-shaped reinforcing rib is disposed between the inner frame of the reinforcing inner frame and the bottom surface of the fixing rib to further strengthen the structural strength of the central supporting column.

In implementation, each of the opening leading edges is provided with a flange protruding in a stepwise manner to enhance the strength of the opening structure, so as to reduce stress concentration and breakage when the opening is collided by the stacker fork.

In practice, the flange extends into the opening with an inclined guiding surface, so that the fork is guided into the opening by the guiding surface when the stacker is ready to displace the pallet.

Compared with the prior art, this creation has the following advantages:

1. The reinforced outer frame and the reinforced inner frame of the central support column are between the bearing surface and the support surface, and the reinforced ribs with the cross-shaped staggered inner circumference of the reinforced inner frame can effectively increase the structural strength of the central support column. The central support column of the conventional pallet is improved and deformed after being used for a long time, which causes the central collapse of the pallet.

2. Each corner end support column is provided with a baffle and a positioning groove, so that the plastic pallets are stacked on each other, and the baffles of the lower plastic pallet are respectively placed in the positioning slots of the upper plastic pallet, so that the plastic pallets are relatively stably stacked. Not easy to dump.

3. When the cargo is placed on the bearing surface, the plurality of baffles can assist the positioning of the cargo, or can be engaged with the baffle after the corresponding structure is arranged at the bottom of the cargo, so as to avoid slipping from the bearing surface.

4. A flange is formed on the front edge of each opening, and the flange is stepped, which can enhance the strength of the opening structure and reduce the stress concentration and fracture of the opening when it is collided.
