Description

Technical Field

[0001] The utility model belongs to the technical field of wooden pallets, in particular to a high-bearing wooden pallet. Background Art

[0002] Wooden pallets are made of logs, which are dried and shaped to reduce moisture and eliminate internal stress. They are then cut, planed, cut, edged, sanded and other finishing processes to form profile plates. The profile plates are bound into semi-finished pallets using nails with anti-slip function (nut structure is used in some cases), and finally finished, anti-slip and waxed. Wooden pallets are the most widely used pallets. Pallets are horizontal platform devices used for packaging, stacking, handling and transportation of goods and products as unit loads. They are generally made of wood, metal, and fiberboard, which are convenient for loading and unloading, and handling unit materials and small quantities of materials:

[0003] The existing Chinese patent publication number CN220032511U is a high-load-bearing wooden pallet: "including a pressure plate, a plurality of support leg assemblies are installed on the lower side wall of the pressure plate, and the plurality of support leg assemblies include a connecting block, a spring is provided on the lower side wall of the connecting block, a support column is provided on the outer side wall of the spring, and the spring and the end of the connecting block away from the pressure plate are both located on the inner side of the support column";

[0004] It improves the load-bearing capacity by setting up a support component in conjunction with a spring, but the load-bearing capacity improvement of a simple spring setting is limited, and the spring elastic force is easily damaged under long-term use and high weight compression. At the same time, the contact area between the support component and the ground is small, the force surface is small, and the stability is poor.

[0005] Therefore, the existing high-load-bearing wooden pallets cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems. Utility Model Content

[0009] Furthermore, a plurality of first anti-skid grooves are evenly formed at the top of the bearing plate, and two limiting holes are evenly formed inside both ends of the bearing plate, and the first anti-skid grooves are convenient for increasing the surface friction of the bearing plate.

The bottom end of the support plate is rotatably connected to a second fixing frame, and a limit block is fixed on the middle part of the bottom end of the second fixing frame. The bearing plate and the bottom plate are supported by the cooperation of the first fixing frame, the support plate and the second fixing frame, thereby further reducing the stress degree of the load-bearing spring.

[0011] Furthermore, two limit grooves are evenly arranged on the top of the bottom plate, and two limit plates are evenly fixed on the top of the bottom plate. The limit block is slidably engaged in the limit groove, and the position of the second fixing frame is limited by the limit block and the limit groove to prevent the second fixing frame from shifting during movement.

The limit rod facilitates the second fixed frame and the return spring to slide along the limit rod.

[0013] Furthermore, one end of the return spring is fixed to one side of the limit plate, and the other end of the return spring is fixedly connected to the second fixed frame. The limit plate slides inside the limit hole, and the position of the load-bearing spring is limited by the limit plate and the limit hole to prevent the load-bearing spring from twisting during the extension and retraction process.

[0014] Furthermore, a plurality of second anti-skid grooves are evenly arranged at the bottom end of the bottom plate, and the second anti-skid grooves are convenient for increasing the surface friction of the bottom plate.
