A step stool with a turnable stool pad is shown in figures 1-6 and comprises a folding ladder body 1, a handrail frame 2 and a rotatable foldable pedal structure 3, wherein the folding ladder body 1 comprises two front tubes 4 and two rear tubes 5, the top ends of the front tubes 4 and the top ends of the rear tubes 5 are rotationally connected with each other through connecting pieces in a pairwise mode, and the pedal structure 3 comprises a plurality of pedal bodies 6 and a plurality of supporting rods 7. The foldable pedal structure 3 in the folding ladder technology is a mature prior art, such as a pedal in a folding household ladder in chinese patent No. CN209637668U, a folding mechanism in a ladder handrail structure in chinese patent No. CN208106298U, etc., and will not be described in detail herein.

The handrail frame 2 comprises an arc-shaped rod 10 and two connecting rods 11, the arc-shaped rod 10 protrudes towards the rear side of the folding ladder body 1, and the two connecting rods 11 are respectively fixed at two ends of the arc-shaped rod 10 and are respectively fixedly connected with the two front tubes 4. The arc-shaped rods 10 are provided with back cushions 22.

The top end of the uppermost pedal body 6 of the pedal bodies 6 is covered with a stool pad 8, and the rear side of the pedal body 6 is rotatably connected with the rear side of the stool pad 8 through a hinge 9.

The top end of the pedal body 6 is provided with a slot 12, and the bottom end of the stool pad 8 is provided with an insert rod 13 inserted into the slot 12. The insertion rod 13 is provided with a through groove 14. The pedal body 6 is provided with a cavity 15. The cavity 15 is communicated with the slot 12 and corresponds to the position of the through slot 14. A clamping rod 16 is connected in the cavity 15 in a sliding mode, one end of the clamping rod 16 penetrates through the cavity 15 and penetrates through the through groove 14, the other end of the clamping rod 16 is connected with a spring 17, and the other end of the spring 17 is connected with the cavity wall of the cavity 15. A first sliding groove 18 leading to the outside of the pedal body 6 is formed in the cavity wall on one side of the cavity 15, and a sliding rod 23 sliding along the first sliding groove 18 is fixed on the clamping rod 16. One end of the slide bar 23 passes through the pedal body 6 through the first slide groove 18 and is fixed with a slide key 19. The sliding key 19 is provided with a plurality of friction grains. The other two side cavity walls of the cavity 15 are both provided with a second sliding chute 20, and the clamping rod 16 is provided with a sliding block 21 which is used for being inserted into the second sliding chute 20 and sliding in the second sliding chute 20.

The working principle is as follows: when the utility model discloses when using as the stool, before 8 upset covers the bench pad on footboard body 6, slide key 19 slides earlier, and slide key 19 drives slide bar 23, and slide bar 23 slides along first spout 18 to drive kelly 16 and remove along cavity 15, when kelly 16 slides in cavity 15, slider 21 slides in second spout 20, has promoted the stability of kelly 16 when sliding in cavity 15. The spring 17 is compressed to form a rebound force, and the end of the clamping rod 16 which originally penetrates out of the cavity 15 gradually retracts into the cavity 15. Then the stool cushion 8 is turned over, the inserted link 13 can be smoothly inserted into the slot 12, the through slot 14 corresponds to the cavity 15, the sliding rod 23 is loosened, one end of the clamping rod 16 penetrates out of the cavity 15 and penetrates through the through slot 14 under the action of the elastic force of the spring 17, the inserted link 13 is fixed in the slot 12, and the connection stability between the stool cushion 8 and the pedal body 6 is improved. At this time, the stool pad 8 stably covers the pedal body 6, and the user can sit on the stool pad 8, and at this time, the armrest frame 2 functions as a backrest, and the arrangement of the back cushion 22 improves the comfort when the armrest frame 2 is used as a backrest.

In a similar way, when the utility model discloses when using as the ladder, slide the feather key 19 earlier, the bench pad 8 is turned over from footboard body 6 through hinge 9 and is opened, and the user foot is stepped on footboard body 6, avoids bench pad 8 to be stepped on dirty. The stool pad 8 of the utility model can not be trampled dirtly by the user, and is prevented from being used as a ladder at every time and then being cleaned.
