Description
Technical field
The utility model relates to the virgin articles for use technical field of baby, is specifically related to a kind of seat.
Background technology
If people's overlong time when taking one's seat can produce sense of fatigue, will want the rest a period of time of lying down.For this reason, someone has invented the seat that backrest can rotate, just can change backrest angle, more common such as seat on work chair, the palace car etc. is arranged, this class seat can be transferred the angle of inclination of backrest big when people normally take one's seat, inclination angle herein is meant the acute angle that backrest and horizontal plane constitute, make backrest comparatively upright like this, lean against more comfortable.The people thinks that recumbency has a rest if take one's seat, and only needs backrest is rotated backward, and turn down at the inclination angle of backrest, and backrest is comparatively lain low, people's rest of just can overlieing, thus improved the comfortableness of seat.Yet, the people be seated and during recumbency the application of force center to seat be different, thereby the center of gravity that causes seat and people to make when as a whole also can sit or lie and change along with the people, and the pin of seat is changeless, will cause the crank of seat like this, thereby influence people's use.Be so equally for the infant, the appropriate seat of center of gravity is safety both, also helps growing up healthy and sound of infant.
The utility model content
The technical problems to be solved in the utility model provides a kind of rational in infrastructure, comfort level is high, center of gravity is variable seat.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the seat that a kind of center of gravity is variable, comprise seat plate, backrest and handrail holder, seat plate is installed on the handrail holder, backrest flexibly connects by the backrest turning cylinder mutually with seat plate, it is characterized in that: the handrail holder is provided with guide rail, and seat plate is actively installed on the guide rail; Be connected with rotating drive link on the backrest, the other end of drive link is installed in rotation on the handrail holder.
Further, described seat plate is equipped with guide wheel, and seat plate is located on the guide rail movably by guide wheel, and it is more steady happy to adopt guide wheel to make when seat plate slides.
Further, described backrest is provided with deck, and seat plate is provided with rotating adjusting rod, and adjusting rod is stuck in the deck, blocks fixing when backrest is transferred to different angles with adjusting rod.
Further, described drive link is installed on the handrail holder by the drive link axle.
The utility model is rational in infrastructure, on the basis of backrest rotatable seat, by on the handrail holder, guide rail being set, seat plate is movably arranged on the guide rail, makes the seat plate can horizontal slip, and rotating drive link is installed between backrest and handrail holder, thereby making the utility model both can be used as common seat uses, can adjust the angle of inclination of backrest again, when adjusting the backrest inclination angle, can also adjust the center of gravity of seat, thus more comfortable in use, safer.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model user mode one schematic diagram;
Fig. 3 is the utility model user mode two schematic diagrames.
Among the figure, 1 is seat plate, and 2 is backrest, and 3 is the handrail holder, and 4 is drive link, and 5 is deck, and 6 is adjusting rod, and 7 is the backrest turning cylinder, and 8 is guide rail, and 9 is guide wheel, and 10 is the drive link axle.
The specific embodiment
In the present embodiment, with reference to Fig. 1, Fig. 2 and Fig. 3, the seat that described center of gravity is variable comprises seat plate 1, backrest 2 and handrail holder 3, and seat plate 1 is installed on the handrail holder 3, and backrest 2 flexibly connects by backrest turning cylinder 7 mutually with seat plate 1; Handrail holder 3 is provided with guide rail 8, and seat plate 1 is actively installed on the guide rail 8; Be connected with rotating drive link 4 on the backrest 2, the other end of drive link 4 is installed in rotation on the handrail holder 3.
The course of work: the user mode of normally taking one's seat, with reference to Fig. 2, this moment backrest 2 near upright, the guide wheel 9 of seat plate bottom is positioned at the rearmost end of guide rail 8, adjusting rod 6 is stuck on the deck 5 on bottom the latch, guarantees that backrest 2 can not move.
User mode lies low, with reference to Fig. 3, in the time of need lying down rest, earlier adjusting rod 6 is taken out, then backrest 2 is pressed to suitable angle, press down in the process of backrest 2,4 pairs of backrests 2 of drive link apply reaction force, and under the effect of drive link 4, backrest 2 applies an active force for seat plate 1 by backrest turning cylinder 7, because the existence of guide rail, seat plate 1 is pushed and moves forward; When stopping to press down backrest 2, seat plate 1 also stops to move forward, and this moment, guide wheel 9 moved to the front end of guide rail 8; Last again adjusting rod 6 being stuck on the suitable latch of deck 5 gets final product, and in whole process, the handrail holder can not change the position all the time as fixed part.Motion state when backrest 2 is heightened is then just opposite.
Below the utility model is described in detail, the above only is one of the utility model preferred embodiment, when not limiting the utility model practical range, be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
