Abstract

The corrugated paper tray includes several longitudinal and transverse beams of folded corrugated paper. The longitudinal and transeverse beams have cross section of isosceles trapezoid. The upper part of the longitudinal beam has downward notch, the lower part of the transverse beam has upward notch, and the longitudinal beams in the lower position and the transverse beams in the upper position are connected through insertion of the notches. Both the longitudinal beams and the transverse beams have recess in the bottom. The tray has high strength and rigidity and its self-locking mechanism ensures no disconnection during transportation.

Description

A kind of corrugated paper tray

The present invention relates to a kind of annex of conveying objects, specifically is a kind of pallet

Along with development of global economy, the transportation volume of goods increases just year by year.In transportation and when placing article, pallet is one of main annex, and present pallet majority is made with timber, so the whole world all will consume a large amount of timber resources and make pallet every year.Well-known, tellurian timber resources is more and more nervous, and disafforestation excessively obtains timber and can destroy natural environment artificially, is not a good approach so make pallet with timber.A kind of in recent years later-model corrugated paper tray is progressively replacing Wooden tray, and it is a kind of environmentally friendly machine, can significantly reduce the consumption of timber resources, the conservation of nature environment, and corrugated paper tray is in light weight, recyclable, therefore is subjected to user's extensive welcome.But the intensity of present corrugated paper tray is relatively poor relatively, and manufacturing process is more numerous, and its reason mainly is that structure is unreasonable, and it is formed by panel and parting bead splicing, and bulk strength and rigidity are relatively poor.

The objective of the invention is: a kind of corrugated paper tray is provided, and this pallet has higher intensity and better rigidity, but also is provided with from locking mechanism except that the advantage with corrugated paper tray, guarantees that pallet can not throw off in handling process all the time.

Technical scheme of the present invention is: a kind of corrugated paper tray, this pallet comprises orthogonal several fixing longitudinal and cross beams, described longitudinal and cross beam forms by corrugated board is folding, and its cross section is isosceles trapezoid, and the first half of longeron is provided with down recess, the lower part of crossbeam is provided with upper notch, longeron and crossbeam be fixedly the time, and longeron is down, and crossbeam is last, the corresponding chimeric connection with upper notch of following recess, longitudinal and cross beam all is provided with groove in the bottom.

The further technical scheme of the present invention is: a kind of corrugated paper tray, this pallet comprises orthogonal several fixing longitudinal and cross beams, and described longitudinal and cross beam forms to the line of centers symmetrical fold by corrugated board, and its cross section is isosceles trapezoid, and top margin is greater than the base, the first half of longeron is provided with down recess, and the lower part of crossbeam is provided with upper notch, and longeron and crossbeam are fixedly the time, longeron is following, crossbeam is last, the corresponding chimeric connection of following recess with upper notch, and longitudinal and cross beam all is provided with groove in the bottom.

One of technical scheme that the present invention is detailed is: a kind of corrugated paper tray, this pallet comprises orthogonal several fixing longitudinal and cross beams, described longitudinal and cross beam forms to the line of centers symmetrical fold by corrugated board, its cross section is isosceles trapezoid, and top margin is greater than the base, the first half of longeron is provided with down recess, the lower part of crossbeam is provided with upper notch, longeron and crossbeam are fixedly the time, longeron is following, crossbeam is last, the corresponding chimeric connection of following recess with upper notch, and longitudinal and cross beam all is provided with groove in the bottom; The cardboard of the following indent of described longeron turns up and the oblique following stay bearing plate that forms, and the side of the upper notch of described crossbeam forms a re-entrant angle by last hypotenuse and following hypotenuse, and when following recess and upper notch were chimeric, stay bearing plate was supported on down hypotenuse and locks calmly.

Two of the technical scheme that the present invention is detailed is: a kind of corrugated paper tray, this pallet comprises orthogonal several fixing longitudinal and cross beams, described longitudinal and cross beam forms to the line of centers symmetrical fold by corrugated board, its cross section is isosceles trapezoid, and top margin is greater than the base, the first half of longeron is provided with down recess, the lower part of crossbeam is provided with upper notch, longeron and crossbeam are fixedly the time, longeron is following, crossbeam is last, the corresponding chimeric connection of following recess with upper notch, and longitudinal and cross beam all is provided with groove in the bottom; The cardboard of the following indent of described longeron turns up and inwardly is folded to form a salient angle, and the side of the upper notch of described crossbeam forms a re-entrant angle by last hypotenuse and following hypotenuse, and when following recess and upper notch were chimeric, salient angle was supported on locking in the re-entrant angle.

In the technique scheme, the cardboard of the groove of described longitudinal and cross beam bottom inwardly and upwards folds, to increase the intensity of longitudinal and cross beam.

In the technique scheme, can also be provided with panel as required at longeron and above the crossbeam.

Advantage of the present invention is:

1. owing to the present invention includes orthogonal fixing longeron and crossbeam, and longeron forms with corrugated board is folding with crossbeam, thus integral intensity than higher, rigidity is relatively good, the number of plies that corrugated board folds is many more, its intensity is high more, rigidity is good more.

2. the cross section of longeron of the present invention and crossbeam is isosceles trapezoid, and its mechanical property is relatively good, and is provided with groove in the bottom of longeron and crossbeam, makes things convenient for fork truck to insert and moves, and the cardboard of groove just in time upwards and inwardly folds, and has more increased the intensity of longeron and crossbeam.

3. longeron of the present invention will descend the cardboard of indent to turn up to form stay bearing plate or strut angle, be supported on the upper notch sidewall of crossbeam and offer nook, make like this when following recess on longeron and the crossbeam and upper notch are chimeric, be split into lockout mechanism, make longeron and crossbeam in the process of moving, be fixed together all the time, can not throw off.

4. the present invention is easy to assembly unit and dismounting, at ordinary times can conserve space, and the time spent is easy to assembly rapidly.
