Abstract

The invention provides a foldable tray, which comprises a panel and a bottom plate, wherein the inner sides of the panel and the bottom plate are connected with fixing pieces through fixing screws, and the fixing pieces are hinged with two pairs of parallel folding pieces through hinges; the folding pieces are provided with fixing grooves, the positioning plates are inserted into the corresponding fixing grooves on the two pairs of folding pieces, and the positioning plates are in interference fit with the fixing grooves; the invention constructs the tray structure by introducing the parallel double-hinge structure and the transverse positioning plate, the transverse positioning plate can be detached under the condition of no use, and the panel and the bottom plate of the tray are folded by the hinge structure, thereby reducing the height of the tray. Effectively save loading space in the storage and transportation process, save the freight, reach the use scene and can realize fast assembly and use, the structure is more dexterous.

Description

Foldable tray

Technical Field

The invention relates to the technical field of industrial logistics, in particular to a foldable tray.

Background

The logistics tray is an essential tool in the development and operation process of modern industry, and the traditional tray is made of solid wood, synthetic wood, aluminum alloy, plastic and the like. The structure of the tray is integral and split, but the whole weight is higher, and the appearance volume is larger, especially for double-sided trays. The tray needs to pile up from top to bottom in the transportation, causes a lot of space extravagant, and to special transport means, in case length and width just can't put with the size deviation of tray to some extent, cause the cost increase of freight. If the size of the tray can be flexibly controlled and the folding structure is formed, the carrying capacity of the transport tool can be effectively improved, and the transport cost is reduced. A nine-leg type single-face tray appears in the market at present, and this tray adopts hollow supporting leg structure, makes the tray can coincide to pile up and store, carry, but this kind of tray panel is mostly the abnormal shape structure who contains the recess, and the danger of damage or toppling over appears easily in the panel of unevenness in the goods loading process.

Disclosure of Invention

In view of the above problems in the prior art, the present invention provides a foldable tray capable of flexibly controlling the size of the tray.

The invention adopts the following technical scheme:

a foldable tray comprises a panel and a bottom plate, wherein the inner sides of the panel and the bottom plate are hinged with a plurality of pairs of parallel folding sheets; the folding piece is provided with a fixing groove, and a positioning plate is inserted into the fixing groove.

Furthermore, fixing sheets are arranged on the inner sides of the panel and the bottom plate; the folding sheet is hinged with the fixing sheet.

Further, the fixing piece is fixed with the panel and the bottom plate through fixing screws.

Further, the number of the fixing screws is not less than two.

Furthermore, the positioning plate is in interference fit with the fixing groove.

In one embodiment, the folding device comprises two groups of folding sheets and positioning plates which are symmetrically arranged.

The invention constructs the tray structure by introducing the parallel double-hinge structure and the transverse positioning plate, the transverse positioning plate can be detached under the condition of no use, and the panel and the bottom plate of the tray are folded by the hinge structure, thereby reducing the height of the tray. Effectively save loading space in the storage and transportation process, save the freight, reach the use scene and can realize fast assembly and use, the structure is more dexterous.

Detailed Description

The invention is further described with reference to the following figures and examples. In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and the like are used in the indicated orientations and positional relationships based on the orientation shown in the drawings for convenience in describing the invention and simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be considered as limiting.

Example 1

The embodiment provides a foldable tray, which comprises a panel 1 and a bottom plate 2, wherein the inner sides of the panel 1 and the bottom plate 2 are connected with a fixing piece 3 through a fixing screw 6, and the fixing piece 3 is hinged with two pairs of parallel folding pieces 4 through a hinge 5; the folding sheet 4 is provided with fixed slot 7, and locating plate 8 inserts in the relative fixed slot 7 on two pairs of folding sheets 4, is interference fit between locating plate 8 and the fixed slot 7.

The specific working mode of the invention is as follows: when the tray did not use, locating plate 9 and the separation of folding piece 4, folding piece 4 took place rotatoryly along hinge 5 to it takes place the dislocation folding to drive panel 1 and bottom plate 2, makes panel 1 and bottom plate 2 take place the coincide, effectively reduces the tray overall height, reduces the required space of transportation, increases transportation quantity, reduces cost of transportation. When the tray used, folding sheet 4 rotated to with 1 or the 2 vertical position of bottom plate of panel, inserted locating plate 8 in fixed slot 7 1 with two folding sheets 4 fixed, formed stable supporting legs, the storage is realized with the transportation function to the tray.

Example 2

The difference between this embodiment and embodiment 1 is that two sets of folding sheets 4 and positioning plates 8 are commonly disposed on two sides of the panel 1 and the bottom plate 2, so that the tray can be weighed more firmly.

It should be understood that the above examples are only for clearly illustrating the technical solutions of the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.

Claims
