The utility model content
The purpose of this utility model just is to provide simple in structure, can change the detachable spring sofa of contained spring at any time.
To achieve these goals, the technical solution adopted in the utility model is such: the utility model comprises base, backrest, two handrails, holder, and base is made of a box body and the fixed muffle that is fixed on box body inside, and spring is housed in the fixed muffle; Holder is one and tips upside down on the base box body that forms interference fits with base, and two handrails and backrest are fixed on the upper surface of holder, have on the upper surface of holder and fixed muffle shape, the corresponding through hole in position; Quill matches with fixed muffle by the through hole on the holder.
The diameter of through hole is greater than the external diameter of quill, and the height of fixed muffle is lower than the upper surface of base, and the internal diameter of quill is greater than the external diameter of fixed muffle.For fixed muffle in the compressed process of spring has guide effect to quill when moving downward, then be fixed on spring in the fixed muffle and be higher than upper surface with holder after base matches, and the length of quill and fixed muffle and greater than the length of spring.
Compared with prior art, advantage of the present utility model is: this detachable spring sofa is simple in structure, when inside has spring to damage, can change spring at any time, and is simple to operate, do not cause waste.
Description of drawings
The utility model is described in further detail with concrete enforcement below in conjunction with accompanying drawing;
Fig. 1 is an embodiment schematic diagram of the present utility model;
Fig. 2 is the structure chart of the utility model base;
Fig. 3 is the stereogram of the utility model holder;
