Description

Adjustable waist rest Technical Field The utility model relates to the technical field of seat lumbar support, in particular to an adjustable lumbar support. Background In modern office, driving and home life, long-time sitting posture maintenance is easy to cause lumbar fatigue and even lumbar vertebra injury, so the lumbar support design of the seat is particularly important. Traditional fixed waist is leaned against and can't adapt to different users' size and position of sitting demand, and current waist is leaned against the structure and generally can not be adjusted, or the operation is inconvenient when adjusting, is difficult to satisfy convenience, reliability and ergonomic demand simultaneously. Disclosure of Invention The utility model aims to provide an adjustable lumbar support which can conveniently and quickly adjust the front and back positions of the lumbar support and adapt to lumbar support requirements of different users. The utility model provides an adjustable waist is leaned on, includes connecting seat, adjustment handle subassembly, grafting subassembly, activity regulating block and activity waist are leaned on the subassembly, adjustment handle subassembly rotates to be installed on the connecting seat, adjustment handle subassembly is close to the position of grafting subassembly is connected with the stopper, the stopper with grafting subassembly activity butt, grafting subassembly activity is pegged graft on the activity regulating block, activity regulating block activity wears to locate in the connecting seat, activity regulating block keep away from the one end of connecting seat with activity waist is leaned on the subassembly to be connected. In the above-mentioned scheme, the connecting seat provides stable support for adjustment handle subassembly, grafting subassembly and activity regulating block, can control grafting subassembly activity lift through adjustment handle subassembly, the activity lift of grafting subassembly is used for realizing locking and the regulation to activity regulating block position, when stopper and grafting subassembly butt, the grafting subassembly is pegged graft on activity regulation, the position of activity regulating block is in the state of locking, when the stopper keep away from the grafting subassembly, the grafting subassembly descends and keeps away from the activity regulating block, just so can adjust the position of activity regulating block wearing to establish in the connecting seat, and then just can adjust the front and back position of the activity waist of the waist of installing on the seat and lean on the subassembly. Further, the connecting seat comprises a main body part and a connecting part, an adjusting channel is arranged on the main body part, the movable adjusting block movably penetrates through the adjusting channel, a connecting groove is formed in the connecting part, and the limiting block is embedded in the connecting groove. In the above scheme, the movable regulating block adjusts the position along the regulating channel, can guarantee the stability that the movable regulating block moved, set up the spread groove on connecting portion and make the stopper inlay the position of establishing at the spread groove, guarantee the compactness of structure, the stopper passes through the adjustment handle subassembly and rotates with the connecting portion to be connected.
