Novel tray

Abstract

The invention discloses a novel tray which comprises a support platform. A lock device is arranged on the support platform, and the lock device comprises a rotating shaft, a locking sheet and a spring. The novel tray is characterized in that a gear mechanism acts on the rotating shaft; the gear mechanism is composed of a limiting rod and a limiting groove in coordination; the limiting rod is eccentrically arranged on the end part of one end of the rotating shaft; the limiting rod extends outwards along the axial direction of the rotating shaft; the end part of the limiting rod is an elastic expansion end; a limiting rod is movably arranged along the radical direction of the rotating shaft; a limiting groove is arranged on the support platform towards the limiting rod; a section of centre wall is arranged at the middle part inside the limiting grove, so the limiting groove is of an arc closed loop structure matched with the movement track of the limiting rod when the rotating shaft rotates, so that the limiting rod can move in a closed loop inside the limiting groove, and is alternatively matched with a first blocking and locating surface and a second blocking and locating surface. The novel tray disclosed by the invention has the advantages of clever design, good flexibility and convenience for switching of locking and unlocking, so the overall mechanism moves smoothly.

Description

technical field [0001] The invention relates to the field of logistics, in particular to a metal pallet used for transporting and storing a plurality of trolleys. Background technique [0002] With the establishment of China's socialist market economic system, the acceleration of the process of world economic integration and the rapid development of science and technology, the logistics industry has become an important means to improve market competitiveness and enhance the core competitiveness of enterprises, but at present, my country's logistics is not yet too modern. As far as the pallets that are necessary in the logistics industry are concerned, the types of pallets are relatively simple, and both the function and the shape are increasingly unable to meet those batches, integrations, and rapid storage and turnover transportation. Due to the large quantity in modern logistics and transportation turnover, boxes full of goods have been put on trolleys for transportation....

AI Technical Summary

Problems solved by technology

In the pallet disclosed in the above patent document, the locking device is operated by pedaling, which is more convenient to use, but the actuating mechanism used to operate the locking device is too complicated and difficult to manufacture and realize, and because the actuating mechanism has two degrees of freedom, Both rotate and move, easy to jam, work poorly
