Description

TECHNICAL FIELD

The present disclosure relates to a connection structure of two opposite slide rails for a drawer basket mounted on a metal shelf which is configured to hang the drawer basket on a bottom of a holding plate of the metal shelf, and the metal shelf contains multiple fixers, wherein a respective one fixer is engaged on a respective one fixing sheet and is configured to engage with the two opposite slide rails of a respective one drawer basket, such that the respective one drawer basket is hung on the bottom of the respective one holding plate easily and flexibly.

BACKGROUND

A conventional metal shelf contains at least one support post, multiple recesses defined on the at least one support post, and multiple plastic fitting elements selectively engaged with the multiple recesses of the at least one support post by using multiple locking ribs of the multiple plastic fitting elements, wherein a taper of a respective plastic fitting element matches with a taper of multiple fitting sleeves of multiple holding plates of the conventional metal shelf so that the multiple holding plates can be engaged with the multiple support posts. The multiple holding plates includes multiple metal bars welded in a grid mesh shape or are made of metal mesh, thus holding objects on the multiple holding plates.
However, the objects will drop to a ground from the multiple holding plates easily without any stop rib arranged on the holding plates. Furthermore, the objects can only be placed on the multiple holding plates, thus having limited accommodation space to the conventional metal shelf.
Referring to FIG. 1, a connection structure of a drawer basket for a conventional metal shelf is shown, the conventional metal shelf 1 containing multiple holding plates 2 and multiple fixers 3 locked on bottoms of the multiple holding plates 2, wherein a respective one holding plate 2 has two opposite slide rails 4, 5 and two coupling sheets 6, 7 connected with the two opposite slide rails 4, 5, wherein a respective one coupling sheet 6, 7 has a receiving orifice configured to screw with a screw bolt. such that the two coupling sheets 6, 7 are locked on a bottom of the respective one holding plate 2, wherein a respective one fixer 3 is connected on the bottom of the respective holding plate 2, and a drawer basket 8 is fitted between the two opposite slide rails 4, 5 so that the drawer basket 8 is fixed, pushed, and pulled to accommodate the objects.
However, the multiple holding plates are screwed on the conventional metal shelf by using the screw bolts to cause a troublesome connection. The multiple fixers are only applicable for a sole size of the multiple drawer baskets, thus having using limitation.
Further reference is made to document DE 12 46 958 B teaching a drawer guide attachable to the underside of a shelf by using holding means, the drawer guide comprising two hollow profile rails, wherein the holding means are in the form of hooks inserted into the rails with extensions and can be pulled out of the rails against the action of at least one tension spring per rail at one or both ends thereof. Further, document US 4 241 668 A shows a device for mounting a container on a horizontal supporting member of a supply shelf.
The present invention has arisen to mitigate and/or obviate the aforedescribed disadvantages.
