Technical field
The present invention relates to chair, specifically is a kind of have wheelchair and dual-purpose chair of rocking chair.
Background technology
Existing wheelchair or rocking chair only can single use use function singleness.
Summary of the invention
The present invention is directed to the above-mentioned defective of prior art, a kind of multifunction chair is provided, so that chair reaches wheelchair and the dual-purpose purpose of rocking chair.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of multifunction chair comprises: a base, and structure is waved for the arc of rocking chair bottom in this base bottom, is provided with a pair of ' ∩ ' shape handrail waving the structure both sides; Fixed block before a pair of, preceding fixed block is fixed on the front side of pair of armrests; A pair of back fixed block, this is separately fixed at the rear side of pair of armrests to the back fixed block; The part of outstanding handrail on the fixed block before a pair of directive wheel, described directive wheel are fixed on, the directive wheel top is a mobilizable pole, pole upper end and pull bar riveted joint, pull bar upper end and spanner riveted joint, and the bottom of spanner is fixed on the preceding fixed block; Left and right manual push boat connects with transverse axis between the push boat, the transverse axis both sides respectively with suspension rod riveted joint, suspension rod upper end and spanner riveted joint, and the spanner bottom is fixed on the fixed block of back; One seat cushion reaches back cushion, is erected on the base respectively.
Preferably, be connected with sleeve and rotating shaft mode between described seat cushion and the back cushion, the sleeve neighboring is provided with several teeth and buckles, and is provided with a gear piece and spring in the rotating shaft, and spring presses gear piece, and the skin of gear piece is provided with the compressing circle that can screw in the rotating shaft in rotating shaft.
Preferably, be provided with one between the described pair of armrests rear side with the fixing Y shape bracing frame of screw.
Preferably, described handrail bottom and arc wave between the structure and rivet with screw.
Preferably, described left and right push boat inboard is provided with gear, and near riveted joint one tommy bar on the transverse axis of gear one side, tommy bar is provided with the tooth cover with the gear coupling.
As can be seen from the above technical solutions, the present invention can promote directive wheel, manual push boat and land easily by pulling the spanner that is arranged on the forward and backward fixed block, realizes the switching of wheelchair and two kinds of user modes of rocking chair.Further, by junction the tooth that can control seat cushion and squab angle is set and buckles and gear piece, reach the purpose of regulating chair cushion and squab angle with the user mode of chair at seat cushion and back cushion.
