[0026] Reference Figures 1 to 4The present application provides a multifunctional folding ladder, including a herringbone folding ladder body 1, the herringbone folding ladder body 1 includes a front ladder 11, a rear support frame 12 hinged to the front ladder 11 and capable of being opened / folded, and pedals 13 arranged in sequence from top to bottom along the front ladder 11, the front ladder 11 and / or the rear support frame 12 are provided with a folding storage rack 2, and the folding storage rack 2 can be stretched / retracted.

[0027] In the present application, a storage rack, a storage box and a folding ladder are combined together, so that the folding ladder can realize the function of a ladder, and when the folding ladder is idle, it can realize the function of a storage rack and a storage box, so as to classify and store items in the home. This not only improves the utilization rate of the folding ladder, but also avoids the waste of resources and high production costs, and greatly improves the user experience.

[0028] Reference Figure 4 In this embodiment, the folding storage rack 2 includes a fixed plate 21 disposed on the back of the front ladder 11, a torsion spring (not shown) disposed in the length direction of the fixed plate 21, a baffle 22 disposed parallel to the fixed plate 21, a folding storage tray (not shown) connected between the fixed plate 21 and the baffle 22, and a folding bracket assembly supported between the fixed plate 21 and the baffle 22. A reel 27 is disposed on the fixed plate 21, and a torsion spring (not shown) is disposed in the reel 27. One end of the folding storage tray 28 is fixed on the reel 27, and the other end of the folding storage tray 28 is fixed to the inner side of the baffle 22. The folding storage rack 2 can be flexibly pulled out and retracted for easy use. Of course, the folding storage rack 2 can also be disposed behind the rear support frame 12.

[0029] In this embodiment, the folding storage tray 28 is a folding net or Oxford cloth. One end of the folding storage tray 28 is wound on the reel 27. When the folding storage tray 28 is pulled out, the torsion spring is twisted. At this time, pulling out the folding storage tray 28 has a damping effect, and the user experience is better. When the folding storage tray 28 is fully pulled out, the folding bracket assembly is also pulled out synchronously to play a supporting role between the fixed plate 21 and the baffle 22 to prevent the folding storage tray 28 from rebounding and retracting under the action of the torsion spring. When the folding bracket assembly is retracted, the folding storage tray 28 is quickly retracted and rolled on the reel 27 under the action of the torsion spring.

[0030] Specifically, the folding bracket assembly includes a first rotating plate 23 and a second rotating plate 24 respectively hinged to the two ends of the fixed plate 21, and a third rotating plate 25 and a fourth rotating plate 26 respectively hinged to the two ends of the baffle 22. The other end of the first rotating plate 23 is hinged to the other end of the third rotating plate 25, and the other end of the second rotating plate 24 is hinged to the other end of the fourth rotating plate 26. The hinged manner makes it easier to pull and fold the folding rack 2. Other folding methods are also possible.

[0031] Reference Figure 2When the folding bracket assembly is working, the first rotating plate 23 and the third rotating plate 25 are located on the same straight line and are perpendicular to the fixed plate 21 and the baffle plate 22; the second rotating plate 24 and the fourth rotating plate 26 are located on the same straight line and are perpendicular to the fixed plate 21 and the baffle plate 22; when folding is required, the first rotating plate 23, the second rotating plate 24, the third rotating plate 25 and the fourth rotating plate 26 rotate around the hinge point respectively, as shown in FIG. Figure 3 As shown, until the first rotating plate 23 and the second rotating plate 24 rotate to a straight line and are parallel to the fixed plate 21 and the baffle 22, the third rotating plate 25 and the fourth rotating plate 26 rotate to a straight line and are parallel to the fixed plate 21 and the baffle 22, push the baffle 22 forward to fix the baffle 22 and the fixed plate 21, and the above-mentioned rotating plates are stored between the baffle 22 and the fixed plate 21.

[0032] Furthermore, the two ends of the fixed plate 21 are respectively hinged to the first rotating plate 23 and the second rotating plate 24 through hinges, and the other ends of the first rotating plate 23 and the second rotating plate 24 are respectively hinged to the other ends of the third rotating plate 25 and the fourth rotating plate 26 through damping hinges 29. The damping hinges 29 provide a damping force when the folding bracket assembly is folded or extended, providing a better user experience.

[0033] Specifically, a first receiving groove (not shown) is provided on the side of the fixed plate 21 facing the baffle plate 22, the first rotating plate 23 and the second rotating plate 24 are hinged in the first receiving groove, a second receiving groove (not shown) is provided on the side of the baffle plate 22 facing the fixed plate 21, the third rotating plate 25 and the fourth rotating plate 26 are hinged in the second receiving groove, and the folding bracket assembly and the folding storage tray 28 are accommodated in the space enclosed by the first receiving groove and the second receiving groove when retracted to avoid being exposed and affecting the overall appearance of the folding ladder.

[0034] Specifically, a plurality of folding racks 2 are provided, and the plurality of folding racks 2 are arranged in sequence from top to bottom along the front ladder 11 . According to customer needs, a plurality of folding racks 2 are provided between two front ladders 11 and / or between two rear support frames 12 .

[0035] Specifically, a pull-out box 14 is provided under the pedal 13, and anti-slip grooves may be provided on the upper surface of the pedal 13. A drawer box 14 is provided under the pedal 13, and the drawer box 14 is used to store items, which is dust-proof and moisture-proof, and has a better storage effect.
