The specific embodiment
The present invention is a kind of sofa backrest jockey, and is as shown in Figure 1, and it comprises the holder 1 that is fixed on the sofa; One end is plugged in the connecting rod 2 on the holder 1, and the fastening seat 3 of backrest that is connected in connecting rod 2 other ends, shown in below among Fig. 2; Said holder 1 comprises the axle sleeve 4 that is sheathed on the connecting rod 2; Be sheathed on the cutting ferrule 5 on the axle sleeve 4, have defining flange 6 on said axle sleeve 4 inwalls, have a plurality of stopper slots 7 that cooperate with defining flange 6 on the said connecting rod 2.After the assembling, connecting rod 2 is inserted in the axle sleeve 4, and defining flange 6 is entrapped in the stopper slot 7, and cutting ferrule 5 is stuck in axle sleeve 4 outer surfaces, and defining flange 6 can not deviate from stopper slot 7, in this way connecting rod 2 is positioned on the holder 1.When needs are regulated backrest height, unclamp cutting ferrule 5 defining flange 6 is deviate from stopper slot 7, then backrest is moved to suitable height; Certainly connecting rod 2 also moves with backrest; And then locking axle sleeve 4, make defining flange 6 snap in the stopper slot 7 here, promptly accomplish the operation of adjustment backrest height.Shown in Fig. 2 top; The end that the fastening seat 3 of said connecting rod 2 and backrest is connected has as the gear 8; The fastening seat of said backrest 3 comprises the securing member 9 that is fixed on the backrest, and is articulated in ratchet 10 and jump ring 11 on the securing member 9, said ratchet 10 with 8 match as the said gear.Two hinge holes are arranged on the securing member 9; As the gear on the connecting rod 28 be articulated in the below hinge hole; Ratchet 10 and jump ring 11 are articulated in the hinge hole of top, and after installing, ratchet 10 is just grabbed as the gear on 8; Jump ring 11 compresses ratchet 10 makes ratchet 10 hold on to as the gear 8, stops as the gear 8 to rotate.When needing the adjustment angle; Pulling jump ring 11 makes ratchet 10 8 throw off and just can make 8 relative securing members 9 rotations as the gear as the gear; After turning to proper angle, unclamp jump ring 11; Ratchet 10 resets and regains one's grip on as the gear 8 and position under jump ring 11 elastic force, can regulate the angle of backrest in this way.
In order to make the more convenient to operate of up-down backrest, said cutting ferrule 5 can be designed to comprise the lock nut 12 and locking double-screw bolt 13 through threaded engagement that locking double-screw bolt 13 is sheathed on the axle sleeve 4.Rotational lock nut 12 makes locking double-screw bolt 13 axle sleeve 4 of holding with a firm grip, and the defining flanges 6 in the axle sleeve 4 more securely are stuck in the stopper slot 7; When reverse rotation lock nut 12 made locking double-screw bolt 13 unclamp axle sleeve 4, the defining flange 6 in the axle sleeve 4 can be deviate from stopper slot 7, the convenient adjusting.In order to make backrest adjusting angle more easily, also be hinged with cam 14 on 8 as the said gear, have the claw that cooperates with ratchet 10 on the said cam 14.Stir cam 14, the claw on the cam 14 is provoked ratchet 10, makes ratchet 10 unclamp as the gear 8, can adjusting angle; After cam 14 was resetted, the claw on the cam 14 can be provoked ratchet 10 to the position of catching as the gear 8, and the elastic force of jump ring 11 also can assist ratchet 10 to reset simultaneously.For the height that makes backrest satisfies multiple requirement, said stopper slot 7 is arranged on the connecting rod 2 by preset space length, and each stopper slot 7 can both be realized a height, and a plurality of stopper slots 7 can be realized a plurality of height.
The present invention can adjust the height and the angle of sofa backrest simultaneously through comparatively simple frame for movement, can satisfy multiple use needs, reaches the effect of one-object-many-purposes.
