The utility model is proposed to provide a chair which can change the slope angle and is used more conveniently and comfortably. The utility model comprises a chair frame with rolling wheels, a chassis and a seat cushion fixed on the chassis, wherein, the front end of a bearing seat of the chair frame is provided with a gap slot, the front end of the chassis is provided with a through slot, one side of the chassis is fixed with a deflector rod by matching a fixed seat with a screw bolt, one end of the deflector rod is bent into a stopping end which is corresponding to and inlaid and inserted into the through hole on the front end of the chassis, and the stopping end is sheathed with a lining. The top end of the chair frame is fixedly provided with the bearing seat of the chair frame, and the bearing seat of the chair frame is pivoted with the chassis and is fixed with the chassis in an elastic way by a screw bolt and a spring.

Description

The office chair at convertible inclination angle

The utility model belongs to chair, particularly a kind of office chair of convertible inclination angle.

General office chair system is supported in chair frame bearing by the chair frame of tool roller, and chair frame bearing system is hubbed at the chassis, fixing cushion again on the chassis.Yet, be provided with the angle-adjusting mechanism that spring cooperates between chassis and chair frame bearing, for the turning angle between chassis and chair frame bearing, the fascinated height of whole office chair promptly is provided, but the turning angle of chassis and chair frame bearing is generally single angle, can't its size of conversion, inconvenience is quite arranged in the use.In addition, the chassis also can provide upper and lower guiding mechanism and backrest angle guiding mechanism simultaneously, complies with own required suitable adjustment for the user.

The purpose of this utility model provides a kind of convertible turning angle size, uses the office chair at more convenient, comfortable convertible inclination angle.

The utility model comprises chair frame, the chassis of tool roller and is fixed in cushion on the chassis; Chair frame bearing front end offers short slot; Chassis front end is provided with groove, and in a side with the fixing driving lever of holder fitted bolt, driving lever one end is bent into the block end of and intercalation corresponding with the saturating groove of chassis front end, the block end is arranged with lining; Chair frame top sets firmly uses the chair frame bearing that articulates with the chassis; Chair frame bearing is by bolt and spring and chassis flexible fastening.

Because the utility model comprises chair frame, the chassis of tool roller and is fixed in cushion on the chassis; Chair frame bearing front end offers short slot; Chassis front end is provided with groove, and in a side with the fixing driving lever of holder fitted bolt, driving lever one end is bent into the block end of and intercalation corresponding with the saturating groove of chassis front end, the block end is arranged with lining; Chair frame top sets firmly uses the chair frame bearing that articulates with the chassis; Chair frame bearing is by bolt and spring and chassis flexible fastening.During adjustment, when the block end of driving lever is positioned at chair frame bearing front end short slot place, chassis relative chair frame bearing, promptly the utility model can be default 15 ° pull than the wide-angle reclining of being about.Move to when leaving chair frame bearing short slot place when driving lever is stirred, the block end block that makes driving lever between chassis and chair frame bearing, chassis relative chair frame bearing, promptly the utility model can be default turning angle and promptly is reduced into about 6 °～8 °; The conversion that just can effectively reach turning angle is selected, conversion turning angle size, use more convenient, comfortable, thereby reach the purpose of this utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As shown in Figure 1 and Figure 2, the utility model comprises chair frame 10, the chassis 20 of tool roller and is fixed in cushion 15 on the chassis 20.

As shown in Figure 3, Figure 4, chair frame 10 tops set firmly and use the chair frame bearing 11 that articulates with chassis 20.Chair frame bearing 11 front ends offer short slot 110.

Chassis 20 front ends are provided with groove 25, and in a side with the fixing driving lever 22 of holder 21 fitted bolts 26, driving lever 22 1 ends are bent into and the saturating groove 25 corresponding block ends 23 of chassis 20 front ends.Block end 23 is intercalated in saturating the groove 25 interior and sheathed linings 24 of chassis 20 front ends.

As shown in Figure 3, Figure 4, chair frame bearing 11 is fixing with chassis 20 by bolt 14 and spring 12, and by adjust button 13 adjust 20 on chair frame bearings 11 and chassis pull degree of tilt the time elasticity.

As Fig. 5, shown in Figure 6, when the block end 23 of driving lever 22 was positioned at chair frame bearing 11 front end short slots 110 places, chassis 20 can be default 15 ° pull than the wide-angle reclining of being about with respect to chair frame bearing 11, and promptly as shown in Figure 1, the utility model is and is about 15 ° of reclinings.But as in the chassis during 20 relative chair frame bearing 11 reclinings, driving lever 22 stirred move to when leaving chair frame bearing 11 short slots 110 places, as Fig. 7, shown in Figure 8, block end 23 blocks that make driving lever 22 are between chassis 20 and chair frame bearing 11, the turning angle of chassis 20 relative chair frame bearings 11 promptly is reduced into about 6 °～8 °, promptly as shown in Figure 2, the utility model is about 6 °～8 ° turning angle.

In sum, the driving lever 22 that short slot 110 that the utility model is offered by chair frame bearing 11 front ends and chassis 20 front ends are provided with, the conversion that can effectively reach turning angle is selected.
