Description
Technical field
The utility model is related to thing to sit on field, more particularly to a kind of headrest linkage mechanism, and specifically one kind is used for
The headrest linkage mechanism of chair.
Background technology
Chair species is various in the market, but, there is the defect of essence, needs of exactly resting the head on are manually adjusted, nothing
Method realize lie down, sit up during direct linkage, cause consumer's experience not good.Disadvantages described above, is all prior art
The central defect that cannot be overcome, inventor will exactly solve these problems.
Utility model content
The utility model solves weak point of the prior art, there is provided a kind of mechanism of the linkage that can rest the head on, its
Concrete technical scheme is as follows：
A kind of headrest linkage mechanism for chair, including handrail, seat and backrest, are fixed with the handrail
First connecting rod, is movably equipped with second connecting rod, and the first connecting rod is flexibly connected by third connecting rod with seat, the third connecting rod
It is flexibly connected by the 5th connecting rod with the second connecting rod, the second connecting rod stage casing is provided with deep-slotted chip breaker, the deep-slotted chip breaker inner sleeve
Damping nut is provided with, the damping nut is fixedly connected by connecting rod with the handrail, the seat is movable with intermediate connector
Connection, the second connecting rod is flexibly connected by six-bar linkage with the intermediate connector, and the intermediate connector is lived with backrest
Dynamic connection, the intermediate connector is flexibly connected with handrail.This structure can realize zero chopping, and using effect is good, and damps spiral shell
Cap can provide necessary damping force.The seat is flexibly connected with connecting rod raised on intermediate connector, the connecting rod and
The tie point of the tie point, the tie point of handrail and intermediate connector and intermediate connector and six-bar linkage of seat is in triangle
Shape, that is, this 3 points not on the same line.This 3 points not ensure that on the same line seat move when not only after by
Between connector post-tensioning, and it has the motion of upward lifting, there is provided more preferable comfort level, and the effect for ensureing zero chopping.
Headrest is movably equipped with the backrest, the headrest is provided with lug boss, and the lug boss top is movably equipped with pull bar, the drawing
The bar other end is flexibly connected with the intermediate connector.Realize headrest linkage.Locking-unlocking device is provided with the middle of the pull bar.It is real
Now rest the head on controllable.
The utility model simply and easily solves the deficiencies in the prior art, and maximized can meet various different crowds
Demand, with good economic worth.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment 1；
Fig. 2 is the side view of the utility model embodiment 1；
Fig. 3 lies down use state figure for the utility model embodiment 1.
Specific embodiment
Embodiment 1
The utility model embodiment 1 is described in further detail with reference to Fig. 1, Fig. 2, Fig. 3：
A kind of headrest linkage mechanism for chair, including handrail 1, seat 5 and backrest 11, it is solid on the handrail 1
Surely first connecting rod 2 is provided with, second connecting rod 3 is movably equipped with, the first connecting rod 2 is flexibly connected by third connecting rod 4 with seat 5,
The third connecting rod 4 is flexibly connected with the second connecting rod 3 by the 5th connecting rod 6, and the stage casing of the second connecting rod 3 is provided with deep-slotted chip breaker
8, damping nut 7 is arranged with the deep-slotted chip breaker 8, the damping nut 7 is fixedly connected by connecting rod with the handrail 1, described
Seat 5 is flexibly connected with intermediate connector 9, and the second connecting rod 3 is connected by six-bar linkage 10 with the activity of the intermediate connector 9
Connect, the intermediate connector 9 is provided with backrest 11, the intermediate connector 9 is flexibly connected with handrail 1.The seat 5 and centre
Raised connecting rod 12 is flexibly connected on connector 9, the tie point of the connecting rod 12 and seat 5, handrail 1 and intermediate connector
9 tie point and intermediate connector 9 is triangular in shape with the tie point of six-bar linkage 10, that is, this 3 points in same straight line
On.Headrest 13 is movably equipped with the backrest 11, the headrest is provided with lug boss 15, and the top of the lug boss 15 is movably equipped with
Pull bar 14, the other end of the pull bar 14 is flexibly connected with the intermediate connector 9.Locking unblock dress is provided with the middle of the pull bar 14
Put 16.Chair leg can be directly set on the utility model handrail 1 also or roller, used as the main body frame of sofa, can also help
Fixed lateral framework between hand 1, then sets chassis, gas bar, chair leg also or horn disk makes as office chair on transverse frame
With.
When in use, user first unscrews damping nut 7, regulation to suitable damping force, then backrest 11, backrest on the lower
11 drive intermediate connector 9, intermediate connector 9 to be rotated with the point that is flexibly connected of handrail 1 around it, promote six-bar linkage 10 to transport forward
Dynamic and connecting rod 12 is moved rearwardly and upwardly；Because connecting rod 12 is moved upwards, the tail end lifting rearwardly and upwardly of seat 5 is driven, sat
Plate 5 drive third connecting rod 4 with it being flexibly connected a little for upward circular motion is done in the center of circle with first connecting rod 2, third connecting rod 4 and
