Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: a folding plastic tray comprises a transverse plate 1, support plates 2, side bases 4 and a central base 5, wherein two ends of the transverse plate 1 are hinged with the side bases 4, the transverse plate 1 and the central base 5 are integrally formed by injection molding, two ends of the support plates 2 horizontally extend outwards to form clamping plates 3, the two support plates 2 are integrally formed by injection molding through the clamping plates 3, the top end surfaces of the side bases 4 and a fixing plate 6 are integrally formed by injection molding, the top end surface of the fixing plate 6 vertically extends downwards to form a groove 7, the fixing plates 6 and the clamping plates 3 on two sides of the groove 7 are respectively provided with a first hole groove 8, the groove 7 and the clamping plates 3 form a clamping groove connection, the transverse plate 1 and the support plates 2 are provided with second hole grooves 9 which are mutually communicated, elastic ropes 10 penetrate through the inside the second hole grooves 9, the elastic ropes 10 are fixedly bonded with the groove walls of the second hole grooves 9 in the transverse plate 1 and the support plates 2, the, and set up the third hole groove 11 that link up each other on the central base 5, the inside screw thread post 12 that has penetrated of third hole groove 11, and the screw thread screw in of screw thread post 12 both ends has the nut, elasticity rope 10 can be connected diaphragm 1 and backup pad 2, and then when backup pad 2 convolutes, every backup pad 2 can not loosen, overall structure can not be loose, backup pad 2 and diaphragm 1 after the coiling simultaneously can form cylindricly, when the use, can be quick with both flat spreads out, rational in infrastructure.

All closely laminate between diaphragm 1 and the backup pad 2 and between 2 adjacent backup pads 2, and diaphragm 1 and 2 top surfaces of backup pad flush each other, diaphragm 1 and backup pad 2 can make up into a complete square body panel like this, can not have the seam, and then article can be steady stack on both surfaces, can not drop down to under the prerequisite of guaranteeing normal use, can carry out the rolling and folding to both, rational in infrastructure.

Central base 5 is fixed bonding with cardboard 3 of its top surface top, and central base 5's quantity is unanimous with diaphragm 1 and 2 quantity sums of backup pad, like this when folding diaphragm 1 and the 2 rolling of backup pad and be cylindricly, central base 5 can be through cardboard 3 with diaphragm 1 and the synchronous rolling of backup pad 2 both, and then make the three make up into a cylindric, reduce holistic area occupied, simultaneously when diaphragm 1 and backup pad 2 tiling are complete square body panel, central base 5 leads to can make up into complete support base, cooperation side base 4, can support diaphragm 1 and backup pad 2 firmly, and overall structure is firm, and intensity is big, can bear the article of great weight.

First hole groove 8 on the fixed plate 6 and the first hole groove 8 that is located the cardboard 3 in the recess 7 link up each other, and the first hole groove 8 inside on fixed plate 6 and the cardboard 3 has penetrated threaded post 12, when the cardboard 3 card at 2 both ends of backup pad is gone into in recess 7 like this, insert threaded post 12 in first hole groove 8 on cardboard 3 and fixed plate 6, and it fixes to spin the nut on threaded post 12, threaded post 12 can be as an organic whole with cardboard 3 and fixed plate 6 connection like this, and then make backup pad 2 and side base 4 firm in connection, thereby holistic intensity is big, and the supporting effect is good.

Fixed plate 6 and recess 7 make up into continuous unsmooth undulation, and the groove depth of recess 7 is unanimous with 3 bottom surfaces of cardboard to the interval of 2 top surfaces of backup pad, go into recess 7 when the cardboard 3 card at 2 both ends of backup pad, backup pad 2 can flush with 6 top surfaces of fixed plate, and then make this tray whole panel be in a plane, when putting article, the condition of slope can not appear in article, and then improved article and stacked the effect, excellent in use effect.

The working principle is as follows: when the device is not used, the nut on the threaded column 12 on the central base 5 can be screwed off, and the nuts on the threaded columns 12 on the clamping plate 3 and the fixing plate 6 can be pulled out, so that the threaded column 12 can be pulled out from the first hole groove 8 and the third hole groove 11, the supporting plate 2 is made of plastic materials, has certain elasticity, and is slightly bent, so that the clamping plate 3 is moved out from the groove 7 and separated from the fixing plate 6, the side base 4 is rotated on the transverse plate 1, so that the side base 4 is moved to the lower part of the bottom end of the transverse plate 1, the supporting plate 2 is wound at the moment, the wound supporting plate 2 and the transverse plate 1 are combined into a cylindrical shape, the side base 4 can be wound along with the supporting plate 2 and is wound inside the supporting plate 2, meanwhile, the central base 5 is also wound inside by the supporting plate 2, the whole volume of the device is small.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
