Problems solved by technology
[0002] With the continuous development of the market economy, the rent of shops has become more and more expensive. In order to save costs and make full use of the existing space, merchants generally set up a loft above the shops for storing goods or resting. The layout expands the space to a certain extent, but at the same time it also brings a problem, that is, it is not easy to set up the stairs for the attic: 1. The tool ladder is used, which will not affect the space, but it is inconvenient to use and unsafe to go up and down ; Two, the use of fixed hard ladders will take up a lot of shop space, so that the advantages of the attic cannot be brought into play

Embodiment Construction
[0018] Such as figure 1 , 2 and 3, a remote-controlled manual dual-purpose rolling ladder includes two parts: a bracket 1 and a rolling ladder body 2, and the rolling ladder body 2 is formed by connecting a plurality of unit steps 21 with hinges 22, and the number of steps In use, it is determined according to the actual height. In this embodiment, seven are used. A circular notch 211 is arranged on the lower corners of the two sides of each unit step 21. There is a page installation groove 2111 in the notch 211. When assembling When the page 22 is installed in the groove formed by the two-unit step gap 211, the two ends of the page 22 are respectively inserted into the installation groove 2111 of the two-unit step and fixed by screwing or riveting, such as Figure 4 Shown, such structure makes each unit step 21 can be folded together to form a hard ladder when rolling ladder stretches, and its load-bearing capacity is good, and it is convenient and safe to go up and down.

The invention relates to a remote-control hand-operated dual-function lifter, which comprises: a support and a main body, wherein said main body is formed by several connected unit step hinged; from the second step, each unit step has one pedal; two end surfaces of unit step can be layered when the lifter is expand; the top of first unit step is connected to the rotation axle hinge on the support; said rotation axle has two chain wheels at two sides of support; each chain wheel via one chain is connected to the chain wheel on the transmission at the bottom of support; and one transmission gear is arranged on the transmission axle, to mesh the power gear of motor axle. The invention uses one transmission device, to coil the main body when the main body is free, with simple structure and high safety.
Description
technical field [0001] The invention relates to a ladder, in particular to a remote-controlled manual dual-purpose winding ladder. Background technique [0002] With the continuous development of the market economy, the rent of shops has become more and more expensive. In order to save costs and make full use of the existing space, merchants generally set up a loft above the shops for storing goods or resting. The layout expands the space to a certain extent, but at the same time it also brings a problem, that is, it is not easy to set up the stairs for the attic: 1. The tool ladder is used, which will not affect the space, but it is inconvenient to use and unsafe to go up and down 2. Using a fixed hard ladder will take up a large amount of shop space, so that the advantages of the attic cannot be brought into play. Contents of the invention [0003] The object of the present invention is to provide a remote-controlled manual dual-purpose rolling ladder, which can be roll...
