The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast the description of drawings specific embodiment of the present utility model.
Please consult Fig. 1～shown in Figure 4 earlier, be respectively three-dimensional appearance schematic diagram of the present utility model, perspective exploded view of the present utility model, the utility model and adjust the three-dimensional appearance schematic diagram in joint and the perspective exploded view that the utility model is adjusted the joint.As shown in the figure: the utility model is a kind of adjustment structure of the chair back, and it is adjusted joint 4, leader 5 and one first flexible member 6 and constituted by a tube connector 1, ShiShimonoseki nodal plate 2, shangguan nodal plate 3.
Be connected to a plurality of extension rods 11 on the above-mentioned tube connector 1.
Each ShiShimonoseki nodal plate 2 is located at the both sides of tube connector 1 respectively.
The movable respectively side of being located at each ShiShimonoseki nodal plate 2 of each shangguan nodal plate 3, and be connected to a support bar 31 on each shangguan nodal plate 3 respectively, and wherein a shangguan nodal plate 3 one sides have a lining 32.
This adjustment joint 4 is incorporated into ShiShimonoseki nodal plate 2 and has between the shangguan nodal plate 3 of lining 32, wherein this adjustment joint 4 includes an axostylus axostyle 41 at least, one is set on the axostylus axostyle 41 and convexes with the ring piece 42 of a plurality of pushing parts 421, one is set on the axostylus axostyle 41 and chassis 43 that inner ring is carved with hackle mark 431, a plurality of top on the chassis 43 pieces 44 of pulling that place, a plurality of second flexible members 45 that place 43 on ring piece 42 and chassis, one is set on the axostylus axostyle 41 and the shrouding disc 46 on sealing chassis 43 and the sealing ring 47 of a fit chassis 43 and shrouding disc 46, and each top pull an end and the pushing part 421 of piece 44 corresponding against, the other end is carved with the grinding tooth line 441 that cooperates with hackle mark 431.
This handle 5 is connected with the axostylus axostyle 41 of adjusting joint 4 by lining 32.
This first flexible member 6 is arranged on the lining 32 and cooperates ShiShimonoseki nodal plate 2 of this adjustment structure one side, shangguan nodal plate 3 to be provided with, and this first flexible member 6 connects ShiShimonoseki nodal plate 2, the shangguan nodal plate 3 that this adjusts structure one side; This first flexible member 6 can be scroll spring, and the two ends of this first flexible member 6 are individually fixed on ShiShimonoseki nodal plate 2 and the lining 32; Be combined into the adjustment structure of a brand-new chair back by said structure.
See also Fig. 5 and shown in Figure 6 again, be respectively user mode schematic diagram of the present utility model and the utility model and adjust the generalized section of joint in the state of adjustment.As shown in the figure: when the utility model uses, the support bar 31 of each extension rod 11 on the tube connector 1, each shangguan nodal plate 3 is combined with the cushion 71 and the chair back 72 of chair tool 7 respectively; So when occupant's desire is adjusted the angle of inclination of the chair back 72, pull this handle 5, making this handle 5 drive the axostylus axostyle 41 of adjusting joint 4 rotates, ring piece 42 on the while interlock axostylus axostyle 41 rotates and each second flexible member 45 of compression again, and make ring each pushing part 421 on the piece 42 recess a pull end of piece 44 of corresponding top respectively, the pull hackle mark 431 on grinding tooth line 441 and chassis 43 of piece 44 other ends of related each top separates, so the occupant can force on the chair back 72, utilize each shangguan nodal plate 3 and the chair back 72 imposed the adjustment that increases angle, and compress this first flexible member 6, when treating that the chair back 72 is adjusted to suitable angle position, decontrol handle 5 again, each second flexible member 45 of order is the state of elasticity recovery, and make ring each pushing part 421 on the piece 42 pass a pull end of piece 44 of this top respectively, related each top pull the grinding tooth line 441 of piece 44 other ends and hackle mark 431 engagements on chassis 43 are used and are finished the adjustment that the chair back 72 increases angles.
