Description

Technical Field

[0001] The utility model relates to the field of pallets, in particular to a molded pallet which is convenient for stacking. Background Art

[0002] When the pallets are not carrying goods, the pallets are stacked together in a straight line from top to bottom to reduce the space occupied by multiple pallets when stored. At this time, the foot pier of the upper pallet is inserted into the cavity of the foot pier of the lower pallet, and the corner of the foot pier of the upper pallet (the junction of the outer side and the bottom surface) contacts the inner side of the foot pier of the lower pallet. The corners of the prior art are boundary lines or rounded corners, and the contact area between the corners of the foot pier of the upper pallet and the inner side of the foot pier of the lower pallet is small and the pressure is large. When the number of stacked pallets is large, the gravity on the lower pallet is large, and the pressure at the corners and the inner side is further increased, causing plastic deformation of the foot pier, and even causing the foot pier to rupture and damage. Utility Model Content

[0003] The utility model aims to solve the above problems and provides a molded pallet that is easy to stack, thereby solving the problem of the small number of stacking layers of pallets in the prior art.

[0021] The utility model is further described below with reference to the accompanying drawings and examples:

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

[0025] like Figures 1 to 5 As shown, this embodiment provides a molded pallet that is easy to stack, including: a load-bearing portion 1 and a foot pier 2, wherein the lower side of the load-bearing portion 1 is fixedly connected to a plurality of foot piers 2, an inner side surface 22 is formed inside the foot pier 2, and an outer side surface 23 is formed outside the foot pier 2, wherein the outer side surface 23 is formed with an inclined surface 21 at the junction with the bottom surface 24 of the foot pier 2. The thickness of the junction (i.e., the corner) of the outer side surface 23 and the bottom surface 24 of the existing foot pier 2 is relatively large, and the inclined surface 21 is arranged at the junction of the outer side surface 23 and the bottom surface 24, thereby increasing the contact area during stacking and reducing the pressure. The inclined surface 21 reduces the thickness at the corner. Since the thickness at the corner of the prior art is too large, reducing the thickness will not affect the strength of the foot pier 2, but can reduce the material used during processing.

[0026] Preferably, the bottom surface 24 is a plane parallel to the horizontal plane.

[0027] Based on the above technical solution, the inner side surface 22 is inclined inward from top to bottom, and the outer side surface 23 is inclined inward from top to bottom. Figure 4 shown.

[0028] Based on the above technical solution, the inward inclination of the inclined surface 21 is greater than the inclination of the outer surface 23 above the inclined surface 21. Figure 5 As shown, the angle between the line connecting the upper and lower ends of the outer side surface 23 above the inclined surface 21 and a horizontal plane is a, and the angle between the inclined surface 21 and another horizontal plane is b, and the angle b is smaller than the angle a.

[0029] On the basis of the above technical solution, the inclined surface 21 is a plane or an arc surface. The plane may be one or more. When the inclined surface 21 is a plurality of planes or arc surfaces, the inclined surface 21 cannot protrude excessively outward, because when the protrusion is small, the inclined surface 21 will be compressed inward and elastically deformed to ensure that the contact area between the inclined surface 21 and the inner side surface 22 of the lower foot pier 2 is basically unchanged from the size when the inclined surface 21 is a plane. When the inclined surface 21 protrudes excessively outward, the contact area with the inner side surface 22 of the lower foot pier 2 will decrease, thereby increasing the pressure, making it easier for the foot pier 2 to be over-pressed and plastically deformed or broken.

[0030] On the basis of the above technical solution, the load-bearing portion 1 is formed with a plurality of reinforcing ribs 11, and the reinforcing ribs 11 are used to strengthen the strength of the load-bearing portion 1, so as to carry heavier goods.

[0031] Based on the above technical solution, the bearing portion 1 is formed with a plurality of support grooves 12, and the support grooves 12 are connected to the inside of the reinforcing ribs 11. When stacking, the lower ends of the reinforcing ribs 11 of the upper tray are inserted into the corresponding support grooves 12 of the lower tray.

[0032] Based on the above technical solution, the distance from one end of the support groove 12 away from the reinforcing rib 11 connected thereto to the junction of the support groove 12 and the reinforcing rib 11 connected thereto is greater than or equal to the wall thickness of the reinforcing rib 11. This is because if it is less than the wall thickness, the support groove 12 is too small to accommodate the bottom surface of the reinforcing rib 11 above.

[0033] On the basis of the above technical solution, the outer side surface 23 is formed with a wave-shaped protrusion 231 , and the wave-shaped protrusion 231 can enhance the strength of the foot pier 2 .

[0034] Based on the above technical solution, the inner side surface 22 is a curved surface, and the lower ends of the two inner side surfaces 22 intersect.

[0035] Based on the above technical solution, the bearing part 1 and the footrest 2 are integrally pressed and formed of wood fiber material.

[0036] When stacking, the trays are placed along a vertical line from bottom to top, and adjacent trays are in contact. Of the two adjacent trays, the inclined surface 21 of the upper tray contacts the inner side surface 22 of the lower tray; at the same time, the lower end surface of the reinforcing rib 11 of the square tray contacts the bottom of the corresponding support groove 12 of the lower tray. The contact area between the inclined surface 21 and the inner side surface 22 is greater than that of the prior art, and at the same time, the lower end surface of the reinforcing rib 11 contacts the bottom of the corresponding support groove 12, further increasing the contact area, thereby reducing the pressure, and thus allowing the trays to be stacked in more layers.

[0037] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
