Abstract

The utility model discloses a telescopic storage box which mainly comprises a plurality of layers of boxes and slide devices. The layers of boxes are integrated through the slide devices. Each slide device mainly comprises a hollow cylindrical guide rail and a ball bearing. The section of each box is quadrangular, the hollow cylindrical guide rails are fixedly arranged on the four vertical sides of the box in each layer, one end of each ball bearing is fixed on the corresponding box, and the other end of each ball bearing is embedded in the hollow cylindrical guide rail of the box on the upper layer and can slide along the hollow cylindrical guide rail. The layers of boxes become smaller layer by layer from top to bottom, and the boxes can be stored in the box at the uppermost end in a sliding mode. The storage space of the telescopic storage box is designed to be in a multilayer drawing adjustable type, space can be reasonably utilized, objects can be placed in a classified mode, and the objects are more orderly stored.

Description

A kind of telescopic parcel tray

Technical field

The utility model relates to article-storage device, is specifically related to a kind of telescopic parcel tray.

Detailed description of the invention

As Figure 1-4, the telescopic parcel tray of one described in the utility model embodiment, mainly comprise upper cartridge body 10, middle box body 11, lower box body 12 and carriage, between three layers of box body, link into an integrated entity by carriage, carriage mainly comprises hollow cylinder guide rail 3 and ball-bearing casing 4, the cross section of box body is all quadrangle, on four vertical edges of every layer of box body, be all fixed with hollow cylinder guide rail 3, ball-bearing casing 4 one end are fixed on box body, the other end is embedded in the hollow cylinder guide rail 3 of its last layer box body and can slides along hollow cylinder guide rail 3, three layers of box body from top to bottom size successively dwindles, can be housed in box body topmost by sliding, the front surface of lower box body 12 is provided with opening, all the other box bodys are all provided with opening at front surface and lower surface, the upper surface 1 of all box bodys and lower surface 9 are for placing object.

Box body is made up of flexible material, the upper surface 1 of box body and lower surface 9 are all provided with the bonding jumper 6 of many horizontal parallel placements, the surface, left and right of box body is all provided with the bonding jumper 6 that two intersections are placed, and bonding jumper 6 is imbedded in flexible material inside, for strengthening the load bearing stength of box body.

Ball-bearing casing is fixed on box body by a sheetmetal 5, and sheetmetal 5 is welded on the outside of hollow cylinder guide rail 3, and flushes with the top of hollow cylinder guide rail.

Hollow cylinder guide rail 3 is provided with guiding breach 8 along its length, for the slide-and-guide to sheetmetal 5.

Hollow cylinder guide rail 3 is being provided with a spherical swollen groove 2 apart from upper/lower terminal one segment distance place, spacing for to ball-bearing casing of spherical swollen groove 2 too much thrown off because of flexible between box body preventing.
