Fig. 1 is a schematic structural view of a chair with a swing arm type chair seat capable of moving back and forth.
In the figure: 1. a backrest; 2. a chair surface; 3. a chair frame; 4. a swing arm column; 5. an upper hinge; 6. a lower hinge; 7. a lower support plate; 8. an upper support plate; 9. a cross beam; 10. a first support; 11. a second support; 12. a lower spring buffer; 13. a third support; 14. a fourth support; 15. an upper spring buffer; 16. adjusting screws are arranged at the lower part; 17. and an upper adjusting screw.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in figure 1, the chair with swing arm type chair seat capable of moving back and forth mainly comprises a chair frame 3, a chair seat 2 arranged above the chair frame 3 and a backrest 1 integrated with the chair seat, wherein the bottom of the chair frame 3 is provided with at least two crossbeams 9, the crossbeams 9 are fixed with a lower support plate 7, the lower support plate 7 is hinged with a swing arm upright 4 through a lower hinge 6, the other end of the swing arm upright 4 is hinged with an upper support plate 8 through an upper hinge 5, the upper support plate 8 is fixed with the chair seat 2, the swing arm upright 4 is arranged between the upper support plate 8 and the lower support plate 7 in a forward tilting mode, namely the upper end of the swing arm upright 4 is tilted forwards, the front side of the upper end of the swing arm upright 4 is provided with an upper adjusting screw 17, the rear side of the lower end is provided with a lower adjusting screw 16, a lower spring buffer 12 is arranged between the swing arm upright 4 and the lower support plate 7 through a first support 10 and, an upper spring buffer 15 is arranged between the swing arm upright post 4 and the upper supporting plate 8 through a third support 13 and a fourth support 14.
The working principle of the chair with the swing arm type chair surface capable of moving back and forth of the utility model is as follows:
when a user sits on the chair surface 2, the gravity of the human body is applied to the upper supporting plate 8 through the chair surface 2, because the swing arm column 4 is of a forward tilting structure, the force applied to the upper supporting plate 8 is decomposed into downward force and forward force, the lower hinge 6 of the swing arm column 4 hinged to the upper supporting plate 8 and the lower supporting plate 7 swings forward with the upper supporting plate 8 and the chair surface 2 moving forward and tilting forward, at this time, the gravity of the human body compresses the upper spring buffer 15 between the upper supporting plate 8 and the swing arm column 4 through the chair surface 2 and the upper supporting plate 8, so that the upper hinge 5 of the upper supporting plate 8 and the chair surface 2 tilts backward with the pivot, thereby keeping the balance state of the upper supporting plate 8 and the chair surface 2, and at this time, the chair surface 2 is tightly attached to the chair frame 3. When the user leaves the seat, lower spring buffer 12 promotes swing arm stand 4 through first support 10 and second support 11, makes swing arm stand 4 resume the normal position, and last spring buffer 15 promotes backup pad 8 and seat 2 through third support 13 and fourth support 14, makes backup pad 8 and seat 2 that is fixed in on backup pad 8 resume the normal position.
The inclination angle of the swing arm upright post 4 can be adjusted by the rotation of the lower adjusting screw 16, and the balance state of the upper supporting plate 8 and the seat surface 2 can be adjusted by the rotation of the upper adjusting screw 17, so that a comfortable angle and position are achieved.
