Description

Technical Field

[0001] This utility model relates to pallets, and in particular lightweight pallets. Background Technology

[0002] Pallets are widely used in production and operation, but the existing pallet bearing surface structure design is unreasonable. In order to have sufficient bearing capacity, the thickness of the bearing surface plate is generally above 0.8mm, which results in high plate cost and heavy weight, which is not conducive to the cost reduction needs of enterprises. Summary of the Invention

[0003] The purpose of this invention is to provide a lightweight pallet with low mass and high structural strength.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A lightweight pallet includes support legs, a frame, and a support panel. The support legs are welded and fixed to the frame. The support panel includes multiple support plate assemblies. Each support plate assembly includes a square tube and bent reinforcing plates disposed on both sides of the square tube. Each bent reinforcing plate includes three support surfaces, which are bent downwards to form reinforcing ribs. First flanges are provided on both sides of the bent reinforcing plate, and the first flanges are perpendicular to the support surfaces. The ends of the bent reinforcing plates are simultaneously welded and fixed to the frame and the support legs. The ends of the square tubes are simultaneously welded and fixed to the frame and the support legs.

[0006] By adopting the above structure, the support plate assembly formed by the combination of the double-reinforced bent reinforcing plate and the square tube greatly improves the overall strength of the support panel. Under the same requirements, the thickness of the plate used for the support panel can be reduced from 0.8mm to 0.5mm, achieving a cost reduction effect of 10%-15%. At the same time, when the forklift lifts the pallet, the bent reinforcing plate deforms slightly, and the square tube bears a large force, which can effectively avoid the bending reinforcing plate from deforming under stress. This utility model reduces the thickness of the support panel plate while ensuring structural strength, reduces the weight of the pallet, and reduces the production and transportation costs of the pallet.

[0007] Preferably, in order to ensure the reinforcing effect of the reinforcing rib, the reinforcing rib includes a bottom and two sides on both sides of the bottom, and the acute angle between the side and the plane of the bottom is α, 75°≤α≤80°.

[0008] Preferably, 78°≤α≤79°.

[0009] Preferably, in order to ensure the structural strength of the bending reinforcement plate, a second flange is provided on the side of the first flange, and the second flange is parallel to the support surface.

[0010] Preferably, to ensure the overall structural strength of the pallet, the support leg includes a first crossbeam, a first longitudinal beam, a second longitudinal beam, a second crossbeam, and a reinforcing beam. The two ends of the first crossbeam are welded and fixed to the lower ends of the first longitudinal beam and the second longitudinal beam, respectively. The two ends of the second crossbeam are welded and fixed to the upper ends of the first longitudinal beam and the second longitudinal beam, respectively. The lower end of the reinforcing beam is welded and fixed to the middle part of the first crossbeam, and the upper end of the reinforcing beam is welded and fixed to the middle part of the second crossbeam. The upper surface of the second crossbeam is welded and fixed to the end of the support plate assembly. Attached Figure Description

[0016] like Figures 1 to 4 As shown, the lightweight pallet of this utility model includes a support leg 1, a frame 2, and a support panel 3. The support leg is welded and fixed to the frame. The support panel includes multiple support plate assemblies. Each support plate assembly includes a square tube 31 and bent reinforcing plates 32 disposed on both sides of the square tube. Each bent reinforcing plate includes three support surfaces 41, which are bent downward to form reinforcing ribs 42. A first flange 43 and a second flange 44 are provided on both sides of the bent reinforcing plate. The first flange is perpendicular to the support surface, and the second flange is parallel to the support surface. The ends of the bent reinforcing plates are simultaneously welded and fixed to the frame and the support leg. The ends of the square tube are simultaneously welded and fixed to the frame and the support leg.

[0017] like Figure 4 As shown, the reinforcing rib includes a bottom 421 and side portions 422 on both sides of the bottom. The acute angle between the side portions and the plane containing the bottom is α, where 75°≤α≤80°. In some embodiments, as a preferred option, 78°≤α≤79°.

[0018] like Figure 2As shown, the support leg includes a first crossbeam 11, a first longitudinal beam 12, a second longitudinal beam 13, a second crossbeam 14, and a reinforcing beam 15. The two ends of the first crossbeam are welded and fixed to the lower ends of the first longitudinal beam and the second longitudinal beam, respectively. The two ends of the second crossbeam are welded and fixed to the upper ends of the first longitudinal beam and the second longitudinal beam, respectively. The lower end of the reinforcing beam is welded and fixed to the middle part of the first crossbeam, and the upper end of the reinforcing beam is welded and fixed to the middle part of the second crossbeam. The upper surface of the second crossbeam is welded and fixed to the end of the support plate assembly.

[0019] By adopting the above structure, the support plate assembly formed by the combination of the double-reinforced bent reinforcing plate and the square tube greatly improves the overall strength of the support panel. Under the same requirements, the thickness of the plate used for the support panel can be reduced from 0.8mm to 0.5mm, achieving a cost reduction effect of 10%-15%. At the same time, when the forklift lifts the pallet, the bent reinforcing plate deforms slightly, and the square tube bears a large force, which can effectively avoid the bending reinforcing plate from deforming under stress. This utility model reduces the thickness of the support panel plate while ensuring structural strength, reduces the weight of the pallet, and reduces the production and transportation costs of the pallet.
