The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail below with reference to the drawings and embodiments.

An expandable tray is shown in figures 1 to 5 and comprises a base frame 1 and a left supporting arm and a right supporting arm 2 which are arranged on the base frame, wherein the tail ends of the supporting arms are positioned outside the base frame, and the tail ends of the supporting arms are provided with supporting parts 3; the foundation frame is provided with a plurality of upper cross beams 4 and a plurality of lower cross beams 5, the upper cross beams and the lower cross beams are arranged in a staggered mode, and the upper ends of the supporting parts are provided with supporting surfaces 6 which are positioned on the same plane with the top surfaces of the upper cross beams. By way of example, the upper cross beams are arranged at equal intervals, and at least 6 upper cross beams are arranged at equal intervals. The lower cross beams are provided with at least 5.

The end of the support arm extending into the base frame is supported by the lower beam, and limited by the upper beam, and each support arm is fixed to the upper beam by a connecting piece, for example, the connecting piece includes a screw installed in the connecting hole. And a connecting hole position 7 is arranged on each upper cross beam corresponding to the supporting arm. When the width of the tray needs to be expanded by the aid of the supporting arms, the connecting pieces on the connecting hole positions can be loosened, then the connecting arms are pulled out by needed lengths, and then the connecting pieces on the connecting hole positions are screwed tightly, so that the connecting arms and the corresponding upper cross beams are fixed.

It should be pointed out that, can be only set up the connecting piece on the connection hole site of an entablature, also can be installation connecting piece on the connection hole site of all entablatures, as long as can fix the support arm can, because entablature and bottom end rail play limiting displacement to the support arm jointly, guaranteed that support arm (tray) whole atress is stable, the connecting piece only play usually prevent that the support arm level from outwards deviating from the effect can, the connecting piece atress is less, consequently adopt ordinary screw as the connecting piece can. By way of example, the connection hole sites include through holes with a counter sink into which the nut portions of the connectors are sunk.

When the supporting arm is fixed on the upper cross beam at the outermost side, the length of the part of the supporting arm extending out of the base frame is less than 1/2 of the width of the base frame, and the part of the supporting arm positioned in the base frame is supported by the lower cross beam at the inner side of the upper cross beam at the outermost side. Usually, the left and the right groups of supporting arms on the foundation frame are symmetrically arranged, and the supporting arms are symmetrically arranged after being stretched and expanded, so that the stress condition is good. By way of example, the base frame is provided with 4-6 left support arms and 4-6 right support arms.

The invention has simple structure and reasonable design, the lower supporting beams are used as the structure reinforcing parts and the supporting feet, the groove formed between two adjacent lower supporting beams is used as the fork tooth to insert when the forklift is inserted, the whole design is ingenious, under the condition that the supporting arms are expanded outwards, the length of the part of the supporting arms extending out of the basic frame is less than 1/2 of the width of the basic frame, and the part of the supporting arms positioned in the basic frame is supported by the lower cross beam on the inner side of the upper cross beam on the outermost side, the structure strength is high, the stability is good, the expandability is good, the extensible support arm can be expanded and used as required, in the maximum extension length range of the supporting arms, the extension length of the supporting arms can be selected as required, the universality is good, and the adaptability is good.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, and any modifications, equivalents, improvements and the like that are made within the spirit and principle of the present invention should be included in the scope of the present invention.
