Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

The embodiment shown in fig. 1 is a pallet panel that facilitates stacking. The material of the cutting pieces in this example is corrugated paper. The cutting piece is provided with a rectangular bottom plate B in the middle. Because the structure of the cutting piece is symmetrical left and right and up and down by taking the center line of the bottom plate as a symmetry axis, only one of the symmetrical structures is introduced below for saving space.

The lower side below of bottom plate is connected with preceding curb plate A, and the left side of preceding curb plate is connected with left front bezel A1, and left front bezel is L shape, and the vertical limit of L shape is with the connecting portion of preceding curb plate left side.

A left front corner support plate D1 extends downward from the left side of the lower side of the front side plate. The left front corner supporting plate is a right trapezoid, a right-angle side above the left front corner supporting plate is connected with the front side plate, and the left side of the left front corner supporting plate is fixedly connected with a left front corner fixing sheet E1 through another right-angle side.

The upper side edge of the left front corner fixing piece is convexly provided with a corner fixing tongue 4, and correspondingly, the public connecting edge of the left front plate and the front side plate is provided with a corner fixing hole 3 in a through way. The maximum width dimension of the corner fixing tongue and the maximum width dimension of the corner fixing hole are in interference fit, and the corner fixing tongue cannot exit automatically after being inserted into the corner fixing hole through artificial deformation.

The left front plate and the front side plate are folded to be in a vertical state and are connected through the corner fixing tongue and the corner fixing hole to form a corner structure of the tray, the corner structure is similar to a right-angle triangular prism lacking a side wall, and the left front corner fixing piece covers the upper end of the triangular prism.

The same structure is provided on the left side of the rear panel C.

The left side of the bottom plate is connected with a left outer side plate B1, and the left side of the left outer side plate is connected with a left fixing plate B3. The width of the left outer side plate and the left fixing sheet corresponds to the width of the L-shaped horizontal edge of the left front plate or the left rear plate. When the folding chair is folded, the L-shaped horizontal edges of the left front plate and the left rear plate are positioned on the same straight line, the left outer side plate is arranged inside the outer fixing plate and the left fixing plate, and the left front plate and the left rear plate are clamped in the middle to realize the fixed connection of the left front plate, the left rear plate and the left rear plate. Therefore, two positioning holes 1 are arranged on the left side edge of the plate in a penetrating mode, correspondingly, a plurality of positioning tongues 2 are arranged on the left side edge of the left fixing piece in a protruding mode, and the positioning tongues and the positioning holes are in one-to-one matching insertion connection relation. In this example, the left outer panel tapers from right to left, and the width of the left fixation plate matches the sum of the lengths of the L-shaped horizontal sides of the left front and rear panels.

The position of the front side plate close to the lower side edge of the bottom plate is provided with a longitudinal positioning hole 5 in the middle, the longitudinal positioning hole is rectangular, the upper side edge of the longitudinal positioning hole is flush with the lower side edge of the bottom plate, and the upper side edge of the longitudinal positioning hole slightly extends to the upper part of the lower side edge of the bottom plate after the thickness of the cutting piece is considered. Correspondingly, a longitudinal positioning tongue 6 is convexly arranged on the lower side edge of the front side plate, and the shape, size and position of the longitudinal positioning tongue are matched and correspond to the shape, size and position of the longitudinal positioning hole. When two trays are stacked up and down, the longitudinal positioning tongue on the lower tray can be inserted into the longitudinal positioning hole of the upper tray in a matching way, so that the upper and lower alignment is realized.

To reduce space, the following description will be given of the step of folding the cut into a tray with an icon instead of the corresponding Chinese name.

Step one, as shown in fig. 2, bending a upwards and inwards to drive a1 and a2 to be vertical; bending the C upwards and inwards to drive the C1 and the C2 to be in a vertical state;

step two, as shown in fig. 3, bending a1 and C1 inwards to the same straight line, and bending a2 and C2 inwards to the same straight line;

step three, turning B1 inwards and upwards to be vertical, then turning B3 inwards and downwards to be vertical as shown in FIG. 4, and enabling the transverse parts of A1 and C1 to be clamped between B1 and B3 through the inserting and fixing of the positioning hole 1 and the positioning tongue 2; in the same operation, the lateral portions of a2 and C2 were clamped between B2 and B4;

step four, turning the D1, the D2, the D3 and the D4 inwards and downwards to a horizontal position as shown in FIG. 5, so that the D1, the D2, the D3 and the D4 respectively cover the corner structures to jointly form the top surface of the tray; at the same time, E1, E2, E3 and E4 are also in the horizontal position;

step five, as shown in fig. 6, bending the corner fixing tongues on E1, E2, E3 and E4 downwards to be vertical;

step six, as shown in fig. 7, inserting each corner fixing tongue into each corner fixing hole correspondingly to lock each corner structure. So far the folding of the tray is completed.

The tray formed by folding the tray cut pieces convenient to stack in the embodiment is made of single cut pieces, and is simple to manufacture and low in cost. Each corner structure all has a backup pad in order to constitute the top surface of tray, more conveniently piles up. When two trays are stacked up and down, the longitudinal positioning tongue on the lower tray can be inserted into the longitudinal positioning hole of the upper tray in a matching way, so that the stacking effect is more neat, and the stacking tray has more advantages in space utilization rate and stacking stability.
