Structure of drawer metal side panels

Abstract

A metal side plate structure of a drawer comprises side plates, a bottom plate and sliding rail assemblies used for opening and closing the drawer. Each side plate is provided with a front connection part connected with a front panel and a rear connection part connected with a rear back plate. The side plates are integrally formed by metal or are formed by fixing at least two metal sheets into a whole after the metal sheets are arranged in a split mode, and a cavity is formed inside. The front connection parts and / or the rear connection parts are arranged in the cavity through fasteners or buckles. The side plates are provided with steps. At least parts of the fasteners or the buckles are arranged on the steps. Each side plate is formed by three steel sections including a side plate outer shell, an upper bearing rail and a lower bearing rail, wherein the upper bearing rail and the lower bearing rail are fixed into a whole through welding and then are arranged at the lower portion of the side plate outer shell through fasteners or a rivet connection mode or a clamping connection mode. The side plate outer shells are provided with the steps, and at least parts of the fasteners or the buckles used for fixing the front connection parts and / or the rear connection parts to a cavity of the upper bearing rail are arranged on the steps. The metal side plate structure of the drawer can improve the intensity of the side plates effectively and is high in practicability.

Description

Technical field [0001] The invention relates to a drawer, in particular to a structure of a drawer metal side plate. Background technique [0002] Chinese Patent Document No. CN102326978A discloses a locking adjustment mechanism for drawer slide rails on January 25, 2012. It includes a coupling seat arranged on the bottom of the drawer, and a lock rod is rotatably connected to the coupling seat. One end of the lock rod A lock tongue is provided with a buckle connection with the slide rail, the other end extends a handle, and the lock tongue is separated from the slide rail by pressing the handle; the lock tongue is provided with an inclined guide surface corresponding to the slide rail, and the rear of the guide surface is stepped locking The stepped locking part is buckled and connected with the lock hole provided on the slide rail, and the number of steps of the stepped locking part is more than two; the lock rod is set on the pillar of the coupling seat through the positioning...

AI Technical Summary

Problems solved by technology

It is said that this structure is equipped with a lever-type lock bar on the connecting seat to fasten and connect with the drawer slide rail. Its locking force is large, and it has the characteristics of quick assembly and low manufacturing cost; The connections are all fixed by fixing parts at one time, and it is extremely inconvenient to disassemble. In case of damage, the whole mechanism must be disassembled and replaced. The maintenance cost is high and the disassembly process is cumbersome. After the drawer is assembled, there are many gaps formed inside, which affects the beauty of the drawer ; and in order to increase the force strength of the side plate, its width is thicker, the use space of the drawer is less, and it is inconvenient in transportation and storage, and the manufacturing cost is high, which can neither meet the user's requirements, nor can the manufacturer and the seller get higher profits from
