After the extension block 202c is extruded into the baffle interval by the extrusion block 101f-2, part of the extrusion block 101f-2 extends out of the baffle, the extrusion block 101f-2 is pushed outwards by the matching pushing plate 202e arranged on the extrusion block 101f-2 through the matching of the pushing block 101f-1 and the matching pushing plate 101e, the cross section of the extrusion block 101f-2 is semicircular, the top of the first baffle 101e-3 is arranged to be arc-shaped, and therefore the extrusion block 101f-2 slides out of the first baffle 101e-3 under the condition of being pushed, and separation is achieved. The first baffle 101e-3 is parallel to the second baffle 101e-4, the upper surface of the extrusion block 101f-2 is flush with the lower surface of the first baffle 101e-3, and the lower surface of the pushing block 101f-1 is flush with the upper surface of the first baffle 101 e-3.
Preferably, the landing main body 100 further includes a stabilizing block 102 connected thereto, and a step 103 disposed on the landing main body 100; the stabilizing block 102 is inserted into the bottom of the landing main body 100, and the step 103 is slidably connected with the landing main body 100. The steps 103 are provided in plural sets, and the steps 103 can slide on the landing main body 100 by a collar engaged with the landing main body 100 to adjust the stepping distance. The stabilizing block 1022 is arranged at the bottom of the landing main body, so that the friction force between the landing main body 100 and the ground can be better enhanced, and the stability of the device is improved.
When the anti-skid platform is used, the landing body 100 is firstly placed on a ladder, the anti-skid platform 200 is unfolded from the landing body 100, then the first movable plate 201 and the second movable plate 202 are unfolded, the second movable plate 202 is placed at the top of the second groove 101d, the second movable plate 202 is fixed by hand, then the fixed sliding part 101e is moved to the top of the second groove 101d, the second baffle 20101e-4 with the arc-shaped end on the fixed sliding part 101e extrudes the extension block 202c towards two sides, the fixed sliding part 101e is continuously moved, the extension block 202c retracts from the gap between the baffles under the action of the limiting spring 202f, the matching hole 202d is matched with the fixed column 101e-6, and therefore fixing of the second movable plate 202 is completed. The fixed sliding part 101e is controlled by the moving driving component 101g to drive the second movable plate 202 to move according to the slope inclination, and the second movable plate 202 is hinged to the anti-skid platform 200, so that the anti-skid platform 200 can adjust a proper angle along with the movement of the second movable plate 202, and at the moment, the first baffle plate 101e-3 and the second baffle plate 101e-4 play a role in limiting and fixing and prevent the second movable plate 202 from falling off due to the fact that the second movable plate 202 inclines to a certain angle. After moving to a proper position, the first movable plate 201 is placed in the first groove 101a, and the first movable plate 201 is supported by the supporting spring 101b and the movable supporting plate 101c in the first groove 101a, so that the first movable plate 201 plays a role of auxiliary support, and the stability of the device is improved. During the storage process, the driving assembly 101g is rotated and moved to slide the fixed sliding member 101e into the separating member 101f, the pressing block 101f-2 presses the extension block 202c, and finally the extension block 202c partially extends out of the baffle, and the extension block 202c is pushed out of the fixed sliding member 101e along the first baffle 101e-3 by the cooperation of the pushing plate 202e arranged on the extension block 202c and the pushing block 101f-1, so that the second movable plate 202 is separated. The second movable plate 202 is first received in the second groove 205, the first movable plate 201 is then received in the first groove 204, and the anti-skid platform 200 is finally rotated and received on the surface of the landing main body 100.
In conclusion, the anti-skid platform 200 arranged on the ladder platform can realize the functions of skid resistance and reaching the proper working height, and the anti-skid platform 200 can be quickly stored when not used, so that the occupied area is reduced, and the carrying is convenient. The angle of the antiskid platform 200 can be freely adjusted by adjusting the fixing component 101, so that the antiskid platform can meet the requirements of working platforms with different slopes, the advantages are more obvious in different working places, and the working efficiency is greatly improved. Folding the accomodating through anti-skidding platform 200, can not lead to the scraping because of the volume is too big when transportation and placing not, reduce area, it is more convenient to use.
