The utility model content
For solving the problems of the technologies described above, the utility model provide a kind of maintenance cost low, use environmental protection plastic-steel chair lift flexibly.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of environmental protection plastic-steel chair lift, comprise backrest, seat and chair leg, and described backrest and described seat are formed in one, and Si Ge angle, described seat bottom surface is equipped with first slot; Described chair leg mainly is comprised of four support columns and left and right chair leg base; Each described support column bottom is provided with at least one screwed hole one, and described left and right chair leg base top surface respectively is provided with two the second slots, evenly is provided with the identical screwed hole two of several and described screwed hole one structure on the wall of the second slot; Described support column upper end is connected in described the first slot, and its lower end is inserted in corresponding described the second slot, and described screwed hole one is connected by screw with described screwed hole two; Described seat and chair leg are made by the environmental protection plastic-steel; The cross section of described left and right chair leg base is trapezoidal.
Preferably, described the first slot is identical with the structure of the second slot.
Preferably, the centre of described left and right chair leg base inboard is equipped with the 3rd slot, and two described the 3rd slots are connected by a cross bar.
Preferably, the bottom surface of described left and right chair leg base is equipped with wear-resistant pad.
By technique scheme, a kind of environmental protection plastic-steel chair lift that the utility model provides, described chair leg mainly is comprised of four support columns and left and right chair leg base; When if support column is damaged, only need to change support column; Equally, if when chair leg base is damaged, only need to change chair leg base, need not replace whole chair leg, therefore maintenance cost is low; In addition, according to requirement for height, selected screwed hole two, be connected by screw selected screwed hole two with corresponding described screwed hole one, realizes changing flexibly chair height, to meet the differing heights demand; Simultaneously, not fragile, frequency of maintenance low and keep in repair more convenient, therefore use flexibly and maintenance cost low.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described.
The front view that Fig. 1 is the disclosed a kind of environmental protection plastic-steel chair lift of the utility model embodiment;
