The single-section ladder frame is provided with hooks at both sides, a pedal crossbar is arranged between the hooks at both sides, the lower ends of the hooks are provided with a connecting groove and a connecting rod used for connecting hooks of another single-section ladder frame, curved parts of the hooks at the upper ends of the hooks extend into the connecting groove, and the curved parts of the hooks are matched with the connecting rod so as to freely connect a plurality of sections of ladder frames according to different operating depths.
Description
Technical field
The utility model relates to the movable cat ladder of the plastics that can independent assortment connect.
Background technology
The workman is when checking operation to manhole in construction, need be deep in the manhole, and the construction workman utilizes rope ladder usually or sets up under the instrument such as long ladder in manhole.The rope ladder ratio is easier to carry, but personnel are not easy to hold center of gravity in climbing up the process of climbing down; Long ladder carries inconvenience, sometimes the bad cooperation of height of falling head and long ladder.
The utility model content
At the defective that exists in the technique scheme, the purpose of this utility model is to provide the movable cat ladder of plastics that can independent assortment connects, and has to be easy to carry, and easy disassembly is the characteristics of combination arbitrarily.
Above-mentioned purpose is achieved through the following technical solutions:
The movable cat ladder of plastics, it is characterized in that: but cat ladder is made up of the single-unit ladder that a plurality of independent assortments connect, described single-unit ladder has the both sides hook, and for riding cross bar, the hook lower end has can be for the link slot and the connecting rod of another single section ladder hanger connection between both sides were linked up with.
The hook sweep of described hook upper end stretches in another single-unit ladder link slot, and the hook sweep cooperatively interacts with connecting rod and just can freely be connected the more piece ladder according to the different work degree of depth.
Described single-unit ladder is one-body molded.
Described single-unit ladder is that plastic material is made, and product weight is light.
Adopt the movable cat ladder of plastics of said structure, can freely connect more piece single-unit ladder according to the different work degree of depth, the height of adjusting required decline on ground is connected and transfers operation, freely connect very simple and convenient mutually, product weight is light, be easy to carry, also easy disassembly is made up arbitrarily, be recoverable to after the end of job and overlapping taking back from the job site deposit.
Description of drawings
Fig. 1 is the structural representation of the utility model single-unit ladder;
Fig. 2 is the schematic diagram of another angle of the utility model single-unit ladder;
Fig. 3 is the utility model user mode reference diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, single-unit ladder 1 has both sides hook 2, is foot-operated cross bar 3 between the both sides hook 2, links up with 2 lower ends and has the link slot 4 and the connecting rod 5 that can supply another single section ladder hanger to connect.It is wide to link up with 2 lower ends, and the upper end is narrow, and the hook sweep 21 of hook upper end stretches in the link slot 4 of another single-unit ladder, and hook sweep 21 cooperatively interacts with connecting rod 5 and just can freely be connected the more piece ladder according to the different work degree of depth.Be formed in one for single-unit ladder 1 in the present embodiment, plastic material is made, and product weight is light.
As shown in Figure 3, single-unit ladder 1 is adjusted required decline on ground height is connected, transfer to operation in the manhole then, freely connect very simple and convenient mutually, product weight is light, be easy to carry, also easy disassembly is made up arbitrarily, be recoverable to after the end of job and overlapping taking back from the job site deposit.
