Serpentiss spring end is connected to can enable more stable the arching upward and protrude framework of Serpentiss spring at framework top.
Sit in frame in above-mentioned support type sofa, cylindric lower positioning tube is passed through by spiral in the lower end of described helical spring
Spring is fixedly connected with lower Serpentiss spring.
Lower positioning tube is enclosed within helical spring and lower Serpentiss spring, helical spring is securely attached to lower Serpentiss spring together with.
Sit in frame in above-mentioned support type sofa, the upper end of described helical spring and upper Serpentiss spring are respectively connected with positioning
Cylinder, in above three, positioning tube is connected by a connecting rope.
Can be by two upper link together stable with helical spring upper end of Serpentiss spring by upper positioning tube and connecting rope.
Sit in frame in above-mentioned support type sofa, described connecting rope is by the upper positioning tube phase string in all elastic support unit
Connection.
Shared its structure of connecting rope of all of elastic support unit is simple, compact, and, adjacent two elastic support unit are also
Can be positioned.
Sit in frame in above-mentioned support type sofa, described connecting rope is flexible cotton cord.
Sit in frame in above-mentioned support type sofa, the sidepiece of described upper positioning tube and lower positioning tube has lacking of running through
Mouthful.
Upper positioning tube just stable being connected on Serpentiss spring and helical spring of energy after indentation, there closure, in the same manner, lower positioning tube
On Serpentiss spring and helical spring under being connected to that can be stable.
Sit in frame in above-mentioned support type sofa, the both sides of described framework have to the recessed supporting part in its underpart.
Compared with prior art, creative two elastic support unit of setting in framework of frame sat by this support type sofa,
So that upper Serpentiss spring arc arched part can stably protrude framework top, the sofa with this seat frame is finally made to have stable bullet
