Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

As shown in fig. 1 and 2, the invention provides a foldable packing box, which comprises a bottom frame 1, a front cross bar 2, a foldable rear turning structure 3, a foldable left turning structure 4 and a foldable right turning structure 5.

The foldable rear overturning structure 3, the foldable left overturning structure 4 and the foldable right overturning structure 5 are hinged with the bottom frame 1 and are arranged to enable the foldable packing box to be switched between a use state and a stacking state through overturning;

when the foldable packing box is in a using state, the foldable rear overturning structure 3 is unfolded and is fixedly connected with the foldable left overturning structure 4 and the foldable right overturning structure 5 in an unfolded state through fixing parts, and two ends of the front cross rod 2 are detachably connected with the foldable left overturning structure 4 and the foldable right overturning structure 5, so that a space for containing glass 18 is formed inside the foldable packing box.

When the glass 18 needs to be loaded, the foldable left turnover structure 4 and the foldable right turnover structure 5 are turned over and erected firstly, the foldable rear turnover structure 3 is turned over and erected, then two sides of the foldable rear turnover structure 3 are fixed with the foldable left turnover structure 4 and the foldable right turnover structure 5 through fixing pieces respectively, and finally two ends of the front cross rod 2 are connected with the foldable left turnover structure 4 and the foldable right turnover structure 5 respectively to reinforce, support and fix. After glass 18 is completely unloaded, when the packing box needs to be turned over, the process is reversed, the packing box is folded, the folded packing box can be stacked, the occupied space of a single packing box is saved, and the turning over efficiency is improved.

As shown in fig. 1 and 5, preferably, the underframe 1 comprises a supporting structure for supporting the glass 18 and a first hinge rod 6 and a second hinge rod 7 fixedly installed at the upper end of the supporting structure, the first hinge rod 6 is hinged to the lower end of the foldable rear turning structure 3, two groups of second hinge rods 7 are provided, and the two groups of second hinge rods 7 are hinged to the lower ends of the foldable left turning structure 4 and the foldable right turning structure 5 respectively.

Preferably, the holding structure comprises a first bracket 8 and a second bracket 9, the second bracket 9 is fixedly mounted on the upper end of the first bracket 8, and the bar-shaped rods 10 of the first bracket 8 and the second bracket 9 are arranged crosswise. The bar-shaped bars 10 of the two carriers form a cross, which improves the bending strength and prevents the carriers from being bent or even broken by the glass 18 fully loaded thereon.

Preferably, the height of the second hinge lever 7 is greater than the height of the first hinge lever 6, the first hinge lever 6 being located inside the two sets of second hinge levers 7. No matter collapsible back flip structure 3, collapsible left flip structure 4 or collapsible right flip structure 5 all have certain thickness, set first hinge bar 6 and second hinge bar 7 to different heights, can be with the smooth folding of each flip structure, avoid each flip structure after folding to make progress protruding condition and appear, the packing box after also being convenient for folds carries out the stack.

It should be further noted that, in order to avoid the long rods of the packing boxes from being crushed during the stacking process of the packing boxes and to achieve the flat stacking, the supporting points need to fall on the upper ends of the four second hinge rods 7, so that the height of the second hinge rods 7 is larger than that of the first hinge rods 6. For the same reason, the first hinge rods 6 are located at the inner sides of the two groups of second hinge rods 7, so that the foldable rear turning structure 3 can be folded first, and the situation that the height of the foldable rear turning structure 3 after being folded is larger than that of the second hinge rods 7 is avoided.

Preferably, the supporting leg 11 has a trapezoidal shape with a gradually increasing sectional area from top to bottom. The supporting area is increased, and the supporting stability is improved.

As shown in fig. 1, 3 and 4, preferably, when the foldable packing box is in the unfolded state, the foldable rear overturning structure 3 is in the inclined state; a stop strip 14 is fixedly arranged at the front side of the second bracket 9. When the foldable rear overturning structure 3 is in an inclined state, the glass 18 loaded in the packing box is also in an inclined state, and compared with the glass 18 in an upright state, the upper glass 18 is pressed on the lower glass 18, so that the interaction force of the upper glass 18 and the bottom frame 1 is reduced, and the bottom edge of the glass 18 is prevented from being cracked. The stop strips 14 are used to restrain the glass 18 in an inclined state to prevent the glass 18 from slipping off.

Preferably, the chassis 1 also comprises forklift plates 15 mounted on both sides of the lower end of the supporting structure. The forklift plate 15 is provided with forklift holes, so that the packing boxes can be conveniently loaded or unloaded from the forklift, and the packing boxes can be conveniently stacked.

As shown in fig. 1 and 5, preferably, the fixing member is a positioning pin, and the positioning pin is used to insert and fix the foldable rear flip structure 3 and the foldable left flip structure 4 or the foldable right flip structure 5 from top to bottom. The locating pin is inserted conveniently and stably, and other fixing parts such as bolts can be adopted.

As shown in fig. 5, preferably, the plugs 16 are fixedly connected to both ends of the cross bar, the insertion plates 17 are fixedly installed at the front sides of the foldable left-turning structure 4 and the foldable right-turning structure 5, and the plugs 16 are inserted into the holes of the insertion plates 17. After the plug 16 is inserted into the plug board 17, the distance between the upper ends of the foldable left turnover structure 4 and the foldable right turnover structure 5 is further determined by the cross bar, so that the two turnover structures are prevented from inclining, and the unfolding state of the packing box is kept stable.

As shown in fig. 5, preferably, the upper end of the cross bar is further provided with a latch 19, and the latch 19 is matched with the latch holes of the foldable left-turning structure 4 and the foldable right-turning structure 5. The cross bar is prevented from being upwardly detached from the foldable left and right flip structures 4 and 5 during the turnaround process.
