The surface of the ladder 1 is provided with the auxiliary device 4, and the auxiliary device 4 can increase the counter weight of the ladder 1 to a certain extent and reduce the probability of overturning of the ladder 1.

The specific arrangement and function of the adjusting device 3 and the auxiliary device 4 will be described in detail below.

Referring to fig. 2, in the present embodiment: adjusting device 3 includes support plate 31, and support plate 31 is located ladder 1 directly below, and the last fixed surface of support plate 31 is connected with two dead levers 32, and two dead levers 32 symmetric distribution are in the both sides of support plate 31, and the inner wall sliding connection of dead lever 32 has slide bar 33. When the ladder 1 is arranged, the support plate 31 is moved to a proper position, the sliding rods 33 are pushed to enable the sliding rods 33 to slide on the inner walls of the fixed rods 32, and the placing plate 34 is fixedly connected to the upper surfaces of the two sliding rods 33. The sliding of the sliding bar 33 causes the placing plate 34 to slide, the placing plate 34 being located on the lower surface of the ladder 1. After the placing plate 34 is moved to a proper position, the ladder 1 is placed on the surface of the placing plate 34, the supporting plate 31, the fixing rods 32, the sliding rods 33 and the placing plate 34 can support the ladder 1 to a certain extent, the hollow blocks 38 are fixedly connected to the side walls of the fixing rods 32, the threaded rods 39 are rotatably connected to the bottom ends of the placing plate 34, and when the position of the placing plate 34 needs to be moved, the threaded rods 39 are rotated on the inner walls of the hollow blocks 38. The outer surface of the threaded rod 39 is in threaded connection with the inner wall of the hollow block 38, the rotation of the threaded rod 39 can drive the placing plate 34 to move, and the position of the placing plate 34 can be adjusted to a certain degree by the threaded rod 39 and the hollow block 38.

Referring to fig. 2, specifically, two rectangular blocks 35 are fixedly connected to the upper surface of the placing plate 34, the side walls of the two rectangular blocks 35 are respectively located at two sides of the ladder 1, and threaded pins 36 are screwed on the rectangular blocks 35 and the inner wall of the ladder 1. After the placement of the ladder 1 has been completed, the threaded pin 36 is turned to the rectangular block 35 and the inner wall of the ladder 1, the threaded pin 36 and the rectangular block 35 being able to restrict the ladder 1 position to a certain extent. The two rectangular blocks 35 and the vertical section of the placement plate 34 constitute a "concave" structure, and when placing the ladder 1, it is necessary to align the ladder 1 in a position between the two rectangular blocks 35. Threaded holes are formed in the surfaces of the rectangular block 35 and the ladder 1, the inner wall of the threaded hole of the rectangular block 35 and the ladder 1 is in threaded connection with the outer surface of the threaded pin 36, and the rectangular block 35 can play a role in limiting the position of the ladder 1 to a certain extent.

Referring to fig. 2, specifically, a sliding groove 37 is formed on a surface of the fixing rod 32, and when the sliding rod 33 slides, the sliding rod slides on an inner wall of the sliding groove 37 of the fixing rod 32. The inner wall of the sliding groove 37 of the fixing rod 32 is connected with the outer surface of the sliding rod 33 in a sliding mode, and the sliding groove 37 can enable the sliding rod 33 to slide.

Referring to fig. 4, in the present embodiment: the auxiliary device 4 comprises storage plates 41, the side walls of the two storage plates 41 are fixedly connected with the two sides of the ladder 1 respectively, a support rod 42 is connected to the inner wall of each storage plate 41 in a sliding mode, and after the ladder 1 is placed, the support rod 42 is pushed to enable the support rod 42 to slide on the inner wall of each storage plate 41. The bottom ends of the two support rods 42 are fixedly connected with a rectangular plate 43. The sliding of bracing piece 42 has driven the rectangle board 43 and has slided, and rectangle board 43 can laminate ground, and storage plate 41, bracing piece 42 and rectangle board 43 can assist support ladder 1 to a certain extent.

Referring to fig. 4, a receiving groove 44 is formed on a side wall of the receiving plate 41, and an inner wall of the receiving groove 44 of the receiving plate 41 is slidably connected to an outer surface of the supporting rod 42, and the supporting rod 42 slides on an inner wall of the receiving groove 44 of the receiving plate 41 when sliding. The box 45 is placed to the last fixed surface of rectangular plate 43 and is connected with, and after rectangular plate 43 placed, with the suitable position on the box 45 of placing the weight plate 46 alignment. The inner wall sliding connection who places box 45 has a plurality of weight plates 46, places box 45 with weight plate 46 again in, weight plate 46 can increase ladder 1's stability to a certain extent, reduces the probability that ladder 1 topples.

Working principle, when the ladder 1 is to be used, the ladder 1 is aligned to a position between two rectangular blocks 35, the ladder 1 is placed on the upper surface of the placing plate 34, and then the threaded pin 36 is turned to the rectangular blocks 35 and the inner wall of the ladder 1, and the threaded pin 36 can limit the position of the ladder 1 on the surface of the placing plate 34 to some extent. Turning the threaded rod 39 again causes the threaded rod 39 to rotate on the inner wall of the hollow block 38, the threaded rod 39 also rotates on the bottom end of the placing plate 34, and the rotation of the threaded rod 39 simultaneously moves the placing plate 34 and the ladder 1. The placing plate 34 drives the sliding rod 33 to slide, the sliding rod 33 slides on the inner wall of the sliding groove 37 of the fixing rod 32, and the supporting plate 31 fixed at the bottom ends of the two fixing rods 32 can increase the contact area of the whole device and the ground to a certain extent. When there is a projection on the ground, the slide bar 33 is retracted into the fixing bar 32 so that the support plate 31 is placed on the projection, and the inclination angle of the whole ladder 1 is inconvenient. When there is a recess on the ground, the slide bar 33 is extended from the fixing bar 32 so that the support plate 31 is placed in the recess, and the inclination angle of the whole ladder 1 is inconvenient. The ladder 1 can be kept stable by adjusting the height of the placing plate 34 to adapt to the change of different ground heights. After the ladder 1 is laid, the ladder can walk on the surface of the step 2 on the ladder 1, and the ladder 1 and the step 2 are made of steel. By providing the adjusting device 3, the ladder 1 can be supported to a certain extent, so that the situation can be adapted to.

After the position of the ladder 1 is adjusted, the support rod 42 is pushed to slide on the inner wall of the storage groove 44 of the storage plate 41, and the rectangular plate 43 and the placing box 45 are driven to move by the sliding of the support rod 42. Stop moving the rectangular plate 43 position after the rectangular plate 43 is placed to the suitable position, then place the inside of placing box 45 with weight plate 46, weight plate 46 can increase holistic stability to a certain extent. When there is a projection on the ground, the rectangular plate 43 is moved in a direction to approach the support plate 31 so that the rectangular plate 43 is placed on the projection. When there is a recess on the ground, move rectangular plate 43 towards the direction of keeping away from backup pad 31 for rectangular plate 43 is put in the recess, thereby adapts to the change of different ground height, through setting up auxiliary device 4, can increase the counter weight of ladder 1 to a certain extent, reduces the probability that ladder 1 topples.
