Description
Technical field
The present invention relates to the seat of a kind of chair back rack and chair seat frame adjustable angle, relate in particular to a kind of seat angle adjustor stack-mounted wrench device that is used for.
Background technology
The seat support of traditional Chinese chair and the chair back are level and vertical basically, and the gravity of human body mainly supports by people's backbone and buttocks, for bending over one's desk working for a long time and the people of office work, are easy to generate fatigue, and diseases such as lumbar vertebrae, cervical vertebra, shoulder week easily take place.
Present automotive seat all have the function of freely adjusting the chair back, and when people pressed the handle of seat angle adjustor and the chair back applied certain external force, the chair back just can recede to reach the chair back angle of people's demand; And when people need recall to initial state with the chair back, only need press the handle of seat angle adjustor once more and keep the chair back to be the stressed state of nature, the chair back just can be replied.Seat angle adjustor generally is made up of chair back gusset piece, seat support gusset piece, core members, handwheel or regulating handle etc., and core members is connected with the seat support gusset piece with chair back gusset piece respectively.In the practical application, necessary parts need be installed in core members, therefore the common more complicated of the process of installing component is necessary to provide a kind of erecting device simple in structure, easy and simple to handle.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, can be used for seat angle adjustor stack-mounted wrench device with what the parts steel bar was packed core members into by single stepping, this device mainly is to make the parts steel bar embed core members by the twisting adjustment (adjusting) lever.
For achieving the above object, the technical solution adopted in the present invention is: be used for seat angle adjustor stack-mounted wrench device, comprise stay bearing plate, it is characterized in that: this device also comprises adjustment (adjusting) lever, draw-in groove piece, adjusting shaft; Adjusting shaft is the axle of a level, and adjusting shaft is fixed on the stay bearing plate by back-up block; Adjustment (adjusting) lever one end is connected on the adjusting shaft, and pressure cap is positioned at the other end of adjustment (adjusting) lever; The next door of adjustment (adjusting) lever is provided with spacing recessed; One end fixed card geosynclinal block of adjusting shaft, the draw-in groove piece is provided with draw-in groove.
Draw-in groove of the present invention engages with steel bar; Steel bar is divided into three segments, i.e. epimere, interlude and hypomere,
The interlude of draw-in groove and steel bar fastens.
Principle of work of the present invention is: the hypomere of steel bar is long, and is no stressed, in advance the hypomere of steel bar embedded in the core members and locked, and this step be can't help apparatus of the present invention and finished; Push down pressure cap, the twisting adjustment (adjusting) lever turns in spacing recessed it, adjustment (adjusting) lever drives the rotation of adjusting shaft, draw-in groove on draw-in groove piece and the draw-in groove piece is rotated, when device when in running order, the interlude of steel bar is fastened in the draw-in groove firmly, so the interlude that the twisting of adjustment (adjusting) lever finally can drive steel bar rotates to an angle, make the owned certain moment of torsion of steel bar, thereby form torsion; Adjustment (adjusting) lever is a fulcrum with spacing recessed of the adjustment (adjusting) lever next door again, and adjusting shaft is pushed along draw-in groove piece direction, and draw-in groove piece and firm bar also move to same direction, and then the epimere of steel bar is embedded in the core members, and this moment, whole steel bar was locked on core members.
Also be connected with chair back connecting panel and seat support connecting panel on the core members, thereby make the torsion of steel bar become the restoring force between the chair back and the seat support, under the situation that seat support is fixed, the chair back has the function of self-return.
Beneficial effect of the present invention: the twisting adjustment (adjusting) lever in spacing recessed, with spacing recessed be the fulcrum propelling movement steel bar core members of the epimere of steel bar can being packed into, operate fairly simple; The torsion of steel bar becomes the restoring force between the chair back and the seat support, and under the situation that seat support is fixed, the chair back has the function of self-return.
Description of drawings
Fig. 1 is a side-looking structural representation of the present invention;
Fig. 2 is a main TV structure scheme drawing of the present invention;
Fig. 3 is a draw-in groove scheme drawing of the present invention.
Wherein, 1 pressure cap, 2 adjustment (adjusting) levers, 3 draw-in groove pieces, 4 stay bearing plates, 5 spacing recessed, 6 adjusting shafts, 7 back-up blocks, 8 steel bars, 9 draw-in grooves, 10a steel bar initial position, the postrotational position of 10b steel bar.
The specific embodiment
Figure is the preferred embodiments of the present invention, below in conjunction with accompanying drawing the present invention is further described, wherein, 1 pressure cap, 2 adjustment (adjusting) levers, 3 draw-in groove pieces, 4 stay bearing plates, 5 spacing recessed, 6 adjusting shafts, 7 back-up blocks, 8 steel bars, 9 draw-in grooves, 10a steel bar initial position, the postrotational position of 10b steel bar.
Referring to Fig. 1, Fig. 2, Fig. 3, be used for seat angle adjustor stack-mounted wrench device, comprise stay bearing plate 4, it is characterized in that: this device also comprises adjustment (adjusting) lever 2, draw-in groove piece 3, adjusting shaft 6; Adjusting shaft 6 is the axle of a level, and adjusting shaft 6 is fixed on the stay bearing plate 4 by back-up block 7; Adjustment (adjusting) lever 2 one ends are connected on the adjusting shaft 6, and pressure cap 1 is positioned at the other end of adjustment (adjusting) lever 2; The next door of adjustment (adjusting) lever 2 is provided with spacing recessed 5; One end fixed card geosynclinal block 3 of adjusting shaft 6, draw-in groove piece 3 is provided with draw-in groove 9.
