Description
Technical field
The utility model relates to a kind of multifunctional folding chair, and it can adjust the angle of backrest, thereby the posture that makes things convenient for the user to select seating, lean to or lie low is used chair.
Background technology
General in the market multifunctional folding chair is by seat support basically, the backrest that is connected in the seat support rear side and can rotates relative to connecting portion, and the support portion that is used to support seat support is formed, top, the seat support left and right sides is provided with handrail, the rear end of handrail is connected rotationally with the backrest left and right sides, be provided with the adjusting device that is used to regulate the relative seat support front and back position of handrail between handrail and support portion or the seat support, this adjusting device is usually by being located at handrail bottom and along handrail length direction grooves distributed separately, and the alignment pin composition that is fixed on support portion or top, the seat support left and right sides, the axis of this alignment pin is basically parallel to ground, and length direction perpendicular to handrail.This chair is when regulating the angle of the relative seat support of backrest, must earlier handrail upwards be lifted, backward or move forward handrail to desired location, again handrail is put down, a groove of handrail bottom is buckled outside alignment pin, thereby make chair keep this stationary state to use for the user, not only operation comparatively bothers, and handrail when lifting and put down, be easy to generate about skew, locate inaccurately, and move chair a little and will make the groove of handrail and alignment pin disengagement, fixing not firm, damage easily, and adjustable range is little, function is comparatively single.
The utility model content
In order to solve existing in prior technology the problems referred to above, the utility model provides a kind of multifunctional folding chair, it adopts the rotation of the regulative mode control backrest of orthoscopic, be not easy to produce skew, accurate positioning, fixed when not only regulating, and built-in regulative mode is not easy to damage, use is also convenient, can prolong the service life of chair greatly; In addition, also can play exercise user's the arm and the effect of waist muscle.
Technical solutions of the utility model are to constitute like this, it comprises seat support, the backrest that is connected in the seat support rear side and can rotates relative to connecting portion, and be used to support the support portion of seat support, top, the seat support left and right sides is provided with handrail, the rear end of handrail is connected rotationally with the backrest left and right sides, it is characterized in that: be provided with the adjusting device that is used to regulate the relative seat support front and back position of handrail between handrail and support portion or the seat support, this adjusting device comprises the outer tube sleeve of fixedlying connected in the same way with handrail, be located at the interior pipe box in the outer tube sleeve, reach the alignment pin that an end is fixedlyed connected with support portion or seat support, in, outer tube sleeve can relatively rotate but can not move to axial, in, but the tube wall of outer tube sleeve is along the corresponding respectively inside and outside elongated slot of communicating pipe that is provided with of the direction that parallels to the axis, and elongated slot one side of interior pipe box is provided with recess successively at intervals along the direction that parallels to the axis; In the other end of alignment pin is provided with and places in the pipe box and can be mutually the internal head that moves freely of pipe box, the size of head makes it can't cross elongated slot or recess is deviate from from interior pipe box, also be provided with the neck that is positioned at elongated slot or elongated slot and recess between head and the alignment pin shank, the size of neck can move freely it in elongated slot or recess.
During use, pipe box in rotating, when making the elongated slot of inside and outside pipe box be in same direction, the neck of alignment pin can freely move forward and backward in the elongated slot of inside and outside pipe box, this moment the user can be as required forward or backward moving hand-rail (handrail drives inside and outside pipe box simultaneously and moves forward and backward, and driving backrest rotates), when adjusting to certain position, pipe box in the backward rotation, the neck of alignment pin is in the recess of interior pipe box, this moment, the inside and outside pipe box pin that is positioned was fixed, and handrail can not continue to move forward or backward again, and chair promptly keeps this stationary state to use for the user.Therefore, than prior art, the utility model technique scheme has following remarkable advantage: be used to regulate handrail adopts orthoscopic relative to the adjusting device of seat support front and back position (rotating thereby drive backrest) motion regulative mode, be not easy to produce skew, accurate positioning, fixed when not only regulating, and built-in regulative mode is not easy to damage, and can prolong the service life of chair greatly.In addition, when the elongated slot of inside and outside pipe box is in same direction, because the neck of alignment pin can freely move forward and backward in the elongated slot of inside and outside pipe box, but user also hand grips hand and ceaselessly carries out elastic move, this moment, backrest also constantly carried out the pitching action, thereby can temper user's the arm and the muscle of waist.
The further improvement of technical solutions of the utility model and the beneficial effect that brings are as described below respectively:
In order further to increase the angle that backrest rotates relative to seat support, enlarge adjustable range, thereby make things convenient for the user freely to select the posture of the most comfortable to use chair, the employing hinge is connected between the connecting portion of the connecting portion of above-mentioned backrest and seat support rear side and handrail and backrest.
