[0030] Embodiment 1

[0031] Reference Figure 1-Figure 5 A novel ladder comprises a positioning plate 1, both ends of the bottom of the positioning plate 1 are rotatably connected with climbing plates 2, so that the opening between the two climbing plates 2 is connected through the positioning plate 1, and a positioning mechanism for increasing stability is installed at the bottom of the climbing plate 2. The positioning mechanism comprises a support block 3, an assembly plate 4, a positioning member, a sliding block 7, a limit block 8, a rotating shaft 9, a threaded column 10, a rotating rod 11, an adjusting worm 12 and an adjusting worm wheel 13. The outer side of the bottom of the climbing plate 2 is rotatably connected with the support block 3, so that when the two climbing plates 2 are opened, the support block 3 can also be connected to the climbing plate 2 through rotation, so that the support block 3 is parallel to the ground;

[0032] The bottom of the support block 3 is internally slidably connected with an assembly plate 4, and a positioning piece is provided at the bottom of the assembly plate 4, so that the assembly plate 4 can be installed at the bottom of the support block 3, and sliding blocks 7 are slidably connected to both sides of the support block 3, and the two sliding blocks 7 are fixed with a limit block 8 on one side away from each other, and the limit block 8 is slidably connected with the assembly plate 4, so that when the limit block 8 is located inside the assembly plate 4, the assembly plate 4 cannot be separated from the support block 3;

[0033] The internal rotation of one end of the support block 3 is connected with a rotating rod 11, and a rotating groove is opened at one end of the rotating rod 11, so that an external tool can enter the rotating groove to drive the rotating rod 11 to rotate. An adjusting worm 12 is fixed at one end of the rotating rod 11 and located inside the support block 3. The top of the adjusting worm 12 is meshed and connected with an adjusting worm wheel 13, so that the rotation of the rotating rod 11 drives the adjusting worm wheel 13 to rotate through the adjusting worm 12, and the stability is increased by the self-locking between the adjusting worm wheel 13 and the adjusting worm 12. A rotating shaft 9 is fixed inside the adjusting worm wheel 13, and threaded columns 10 are fixed on both sides of the rotating shaft 9, and the threads of the two threaded columns 10 are opposite. The outer part of the threaded column 10 away from the rotating shaft 9 is threadedly connected to the sliding block 7, so that the rotation of the two threaded columns 10 drives the two sliding blocks 7 to move in opposite directions;

[0034] The positioning piece is a positioning cone 5, and the positioning cones 5 are evenly fixed on the bottom of the assembly plate 4, so that the positioning cones 5 can increase the friction and stability effect on soft ground or concrete ground and other non-smooth areas. The positioning piece is an anti-skid plate 6, and the anti-skid plate 6 is fixed on the bottom of the assembly plate 4. The material of the anti-skid plate 6 is rubber, so that the friction effect can be increased when used on a smooth ground.

[0035] The use process of the new type of ladder provided by the utility model is as follows: first, according to whether the position where the ladder is used is a smooth plane or a non-smooth plane, an assembly plate 4 with an appropriate positioning piece is selected, and the assembly plate 4 is installed on the bottom of the support block 3 by sliding. Then, a tool is used to enter the interior of the rotating groove to drive the rotating rod 11 to rotate, and the rotation of the rotating rod 11 drives the meshing adjustment worm gear 13 to rotate through the adjusting worm 12, and the rotation of the adjusting worm gear 13 drives the rotating shaft 9 to drive the two sliding blocks 7 with opposite thread rotation directions to move in the opposite direction. Through the reverse movement of the two sliding blocks 7, the sliding block 7 drives the limit block 8 to move, so that the limit block 8 enters the interior of the slidingly connected assembly plate 4 to fix the assembly plate 4, and then the two climbing plates 2 are opened, so that the support block 3 at the bottom of the climbing plate 2 is parallel to the ground through the rotation connection, and the positioning piece at the bottom of the support block 3 is in contact with the ground to increase stability.

[0036] Embodiment 2

[0037] Reference Figure 2 and Figure 6 A new type of ladder, a support mechanism is installed at the bottom between the two climbing plates 2, the support mechanism includes a limit plate 14, a stop frame 15, a stop plate 16, a limit column 17 and a tension spring 18, the adjacent ends of the two climbing plates 2 are rotatably connected to the limit plate 14, and the stop frame 15 is rotatably connected between the two limit plates 14, so that when the two limit plates 14 are parallel to each other through rotation, the tops of the adjacent ends of the two limit plates 14 contact the stop frame 15, and at this time the stop frame 15 cannot continue to descend on the limit plate 14, providing support force, and the two climbing plates A stop plate 16 is fixed at one end adjacent to the other and at the bottom of the limit plate 14. The stop plate 16 and the climbing plate 2 are in an inclined state, so that when the climbing plate 2 is opened, the bottom of the limit plate 14 contacts the top of the stop plate 16. The inside of the stop plate 16 is slidably connected to the limit column 17, and the outer side of the top of the limit column 17 is slidably connected to the limit plate 14. A tension spring 18 is sleeved on the outer side of the limit column 17. The top of the tension spring 18 is fixed to the stop plate 16, and the bottom of the tension spring 18 is fixed to the limit column 17, so that the descent of the limit column 17 drives the tension spring 18 to stretch.

[0038] In this embodiment, the two anti-rotation plates 16 are both provided with a limit column 17 and a tension spring 18 inside. In other embodiments, the limit column 17 and the tension spring 18 may be provided on only one anti-rotation plate 16 .

[0039] The use process of the new type of ladder provided by the utility model is as follows: when the two climbing plates 2 are opened, the two assembly plates 4 are connected to the climbing plates 2 through the rotation connection and the anti-rotation frame 15 that is rotationally connected between the two assembly plates 4, so that the opening of the two climbing plates 2 allows the two limit plates 14 to gradually become parallel. At this time, when the two limit plates 14 are parallel, the anti-rotation frame 15 contacts and limits the top of the limit plate 14, and at the same time pulls the limit column 17 to allow the limit column 17 to descend and drive the tension spring 18 to stretch. When the bottom of the limit plate 14 contacts the top of the anti-rotation plate 16, the limit column 17 is released, and the limit column 17 is allowed to enter the sliding connection of the limit plate 14 through the rebound after the tension spring 18 is stretched, so as to increase the positioning.

[0040] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
