[0025] See also Figure 1-Figure 4 As shown, the utility model provides a technical solution:

[0026] A retractable stepladder with a storage board and a seat cushion comprises a first ladder body 100 and a second ladder body 200 which are symmetrically arranged. The tops of the first ladder body 100 and the second ladder body 200 are hinged to facilitate adjustment of the angles of the first ladder body 100 and the second ladder body 200. The first ladder body 100 and the second ladder body 200 are both connected by a plurality of steps that can be flexibly fitted together to facilitate storage and transportation. A pedal is provided in the middle of each step, and a telescopic mechanism is provided at the bottom of the pedal. The telescopic mechanism is used to fix the steps at each level. A top seat cushion 201 is provided on the top of the second ladder body 200, so that workers can sit down for installation when the installation time is long. The adjacent two side walls of the top seat cushion 201 are opened, and the top seat cushion 201 is hollow inside to form a accommodating chamber. A storage plate A3 is rotatably connected to the inside of the accommodating chamber, and a storage plate B4 is hinged on one side of the storage plate A3. The storage plates A3 and B4 are used to temporarily hold maintenance tools, so that workers can take the required tools at one time, without having to go up and down frequently or asking others to run back and forth to help get tools, thereby improving work efficiency.

[0027] In this embodiment, the multi-step ladder includes a first step 101, a second step 102, a third step 103, a fourth step 104, and a fifth step 105, which are movably connected from bottom to top. Each of the first step 101, the second step 102, the third step 103, the fourth step 104, and the fifth step 105 is provided with a pedal in the middle, and a telescopic mechanism is provided at the bottom of the pedal. The five steps 105 of the first ladder body 100 are hingedly connected to the five steps 105 of the second ladder body 200. It is worth noting that more steps can be designed according to actual needs and are not particularly limited here.

[0028] In this embodiment, the telescopic mechanism includes a latch 501, a latch base 502, and a knob 6. The knob 6 includes a rotating column 61 and a rotating rod 62. One end of the rotating column 61 is rotatably set at the center position of the bottom of the pedal, and the other end of the rotating column 61 is fixedly connected to the middle of the rotating rod 62. Two groups of latch bases 502 are symmetrically arranged on both sides of the knob 6. The latch base 502 is fixedly welded to the bottom of the pedal. Second through holes 504 are symmetrically opened on both sides of the latch base 502, and a latch 501 is movably arranged in the second through hole 504. First through holes 503 are correspondingly opened on both sides of the first step 101, the second step 102, the third step 103, the fourth step 104, and the fifth step 105. The rotating rod 62 is respectively engaged with the latches 501 on both sides. When the stepladder is folded, the latch 501 is set inside the latch base 502, and each step can be movably accommodated. When a worker needs to carry out maintenance or installation, the stepladder can be moved out. First, the stepladder is placed below the required location, and then each step is pulled out one by one. When the fifth step 501 is pulled out, if the height reaches the set height, the rotating rod 62 at the bottom of the pedal of the fourth step 401 is rotated to drive the latch 501 to move in the second through hole 504. The latch 501 will pop out horizontally until the end of the latch 501 away from the rotating rod 62 is inserted into the first through holes 503 on both sides of the fourth step 401, thereby fixing the fifth step 501. When more steps are needed, each step is fixed in sequence.

[0029] In this embodiment, a limiting column 5011 is further provided in the middle of the latch 501 . The limiting column 5011 is provided between the second through holes 504 on both sides. The movement of the latch 501 is limited by the limiting column 5011 .

[0030] In this embodiment, a slide groove is provided at the top of the five-step ladder 105, and the slide groove is consistent with the rotation direction of the first ladder body 100 and the second ladder body 200. The bottom of the top seat cushion 201 is movably connected to the slide groove of the five-step ladder 105 by bolts, and the top seat cushion 201 is supported by the five-step ladder 105. The bolts can move in the slide groove, and the angles of the first ladder body 100 and the second ladder body 200 and the support position of the five-step ladder 105 on the top seat cushion 201 can be adjusted as needed.

[0031] In this embodiment, a bearing assembly 202 is provided at the connection between the adjacent two side walls of the opening of the top seat cushion 201. The bearing assembly 202 is rotatably connected to the storage board A3. After the storage board A3 is rotated 180° to open, the storage board B4 is opened, one side of which is hinged to the storage board A3, and one side of which is in contact with the side wall of the top seat cushion 201, so that more maintenance tools can be placed to prevent the maintenance tools from falling.

[0032] In this embodiment, an anti-slip pad 106 is provided at the bottom of the first step 101 to increase the friction between the first step 101 and the ground, prevent sliding during use, and further ensure the safety of workers.

[0033] When the retractable step ladder with a storage board and a seat cushion of this embodiment is used, the step ladder is first placed under the required position, and then each step is pulled up one by one. When the five-step ladder 501 is pulled up, if the pulled-out height reaches the set height, the rotating rod 62 at the bottom of the pedal of the fourth step 401 is rotated to drive the latch 501 to move in the second through hole 504, and the latch 501 will pop out horizontally until the end of the latch 501 away from the rotating rod 62 is inserted into the first through hole 503 on both sides of the fourth step 401, and the five-step ladder 501 is pulled up. The ladder is fixed to each step 501. When more steps are needed, each step is fixed in sequence. The worker can then carry the tools and climb the stepladder. When the worker is in a convenient position, the worker rotates the storage plate A3 180 degrees using the bearing 202 and then opens the storage plate B4 using the hinge. The storage plate B4 abuts against the top base plate 201 at one end, ensuring that it can accommodate more tool parts. The worker can then place the tools on the storage plates A3 and B4, then straddle the top base plate 201 to begin work. Disassembled parts and items can also be placed on the storage plates A and B. When the work is completed, the storage plates A3 and B4 are folded and stored in the storage chamber of the top base plate 201. The latch 501 is then retracted inward by rotating the rotary rod 62 in the opposite direction. The steps can then be folded up in sequence. When all are folded up, they can be moved and placed in a corner of the equipment room.
