Description
Technical field：
The present invention relates to the improved technologies of tilting seat regulating member, and in particular to a kind of seat folds degree linkage locking dress
It puts.
Background technology：
At present, existing tilting seat can only be hinged by backrest and seat, and passes through both control amplitude of fluctuation and lock
Dead relationship realizes the folding extent control to rumble seat.But if by backrest and leg support ganged movement, then interlocking bar must
So there are certain amplitudes of fluctuation, it is impossible to always in the movement of horizontal or certain angle of inclination.Since the pendulum motion of interlocking bar is closed
System arbitrarily swings the organization plan locked there is no suitable for interlocking bar at present.
Invention content：
The problem of present invention can not realize backrest and leg support linkage for current tilting seat and linkage process exist can not
It is effectively locked that a kind of seat is provided and folds degree linkage locking device thus the problem of can not being positioned to backrest and leg support,
Suitable for the rumble seat for adjusting backrest and leg support linkage.
Technical solution：A kind of seat folds degree linkage locking device, and including seat board and backrest, the rear end of wherein seat leads to
Later the lower end of dead axle and backrest is hinged, while is hinged with leg support by preceding dead axle in the front side of seat, will be set on the upside of leg support
It is equipped with more than preceding dead axle and is bent downwardly the leg support drive rod extended to；And it will be provided on the downside of the backrest more than rear dead axle
And it is bent downwardly extended backrest drive rod；The end of the backrest drive rod and leg support drive rod is articulated with respectively by inner shaft
In the axle sleeve at the both ends of interlocking bar；Sizing axis is provided in the middle part of interlocking bar；Support frame is fixed in the seat side, is being propped up
Seat side inside support frame is hinged with left swing piece and right pendulum by left dead axle and right dead axle respectively, left swing piece and right pendulum
The flat hole of automatic adjustment is respectively arranged below, two flat holes of automatic adjustment are sleeved on simultaneously on the sizing axis；Simultaneously described
Screw thread is equipped with locking pin on support frame, and the end which is located on the inside of support frame is fixed with platen, and the platen is for same
When squeeze the left swing piece and right pendulum.
Divide on the surface docked on the butting surface of the left swing piece and right pendulum and with seat side in left swing piece
Frictional layer is not provided with it.
The interlocking bar be divided into two sections it is independent divide bar, one of them divides the end of bar to be fixed with length adjustment casing, separately
One point of bar penetrates in the length adjustment casing, and length adjustment sleeve port is provided with lock-screw.
Tension spring is connected between the either end of the interlocking bar and seat bottom.
The present invention has the advantages that：The present invention can lock tilting seat after arbitrary swing, and grasp
Make simple and convenient.
By the above structure scheme of the present invention, the structure of current existing tilting seat can be simplified, without gas
The structures such as cylinder are only a kind of linkage locking relationships.So the cost of rumble seat can be significantly reduced, but still it can reach and appoint
The adjusting of meaning exhibition folding position and the purpose locked at any time.
The present invention is mainly to provide a kind of linkage locking scheme.No matter how interlocking bar swings when being adjusted
And movement, the present invention can ensure to carry out it function that is locked and discharging in its arbitrary swing position.
The present invention be suitble to currently used for carried out on the basis of lying posture armchair structure simplify improvement, suitable for office seating
Or executive chair is transformed, and overcomes the problems, such as that existing lying posture seat lacks leg support or leg support design is unreasonable.
The present invention can by control interlocking bar length adjustment cover inner telescoping tube degree, reach control linkage pole length
Purpose.Carry out synchronizing moving at different angles both so as to when backrest and leg support Synchronization Control is carried out, keep.

Specific embodiment：
Embodiment 1：Seat as shown in Figure 1 folds degree locking device, including seat board, backrest 2 and leg support 3 and adjustment portion
Part.The rear end of seat 1 is hinged by the lower end of rear dead axle 4 and backrest 2, and leg support is hinged with by preceding dead axle 5 in the front side of seat 1
3.Moreover, the upside of leg support 3 is provided with more than preceding dead axle 5 and is bent downwardly the leg support drive rod 7 extended to.And it is leaned on by described in
The downside of the back of the body 2 is provided with more than rear dead axle 4 and is bent downwardly extended backrest drive rod 6.
The end of backrest drive rod 6 and leg support drive rod 7 is articulated with the axle sleeve at the both ends of interlocking bar 8 by inner shaft respectively
It is interior.
It is shown in Figure 2 for backrest 2 and leg support 3 to be controlled to swing the regulating member of degree, it is set at 8 middle part of interlocking bar
There is sizing axis 13, sizing axis 13 can swing with interlocking bar 8 and be moved.Support frame 21, Fig. 1 is fixed in 1 side of seat
With omit the supporting rack in Fig. 2, but in Fig. 4 it can be seen that the structural relation of the supporting rack.From the appearance, support frame 21 wraps
Shell has been included, it can be by regulating member therefore inside support frame 21.
With reference to Fig. 2 and Fig. 4,1 side of seat inside support frame 21 is hinged by left dead axle 12 and right dead axle 14 respectively
There are left swing piece 91 and right pendulum 92, and flat hole 15 automatically adjusted in left swing piece 91 and being respectively arranged below for right pendulum 92,
Two flat holes 15 of automatic adjustment are sleeved on simultaneously on the sizing axis 13.
Meanwhile as shown in figure 4, screw thread is equipped with locking pin 17 on support frame 21, which is located at support frame 21
The end of inside is fixed with platen 18, which is used to squeeze the left swing piece 91 and right pendulum 92 simultaneously.No matter interlocking bar 8
How to swing and move when being adjusted, the present invention can ensure its arbitrary swing position all it is carried out it is locked and
The function of release.
When being drawn by applying tension spring to interlocking bar 8, backrest 2 and leg support 3 can be kept while swing to seat
Position or level bed position, then the retaining mechanism of the present embodiment is coordinated to reach best use effect.
In addition, it is docked on the butting surface of left swing piece 91 and right pendulum 92 and in left swing piece 91 with 1 side of seat again
Surface on be respectively arranged with frictional layer.The outer section of locking pin 17 is provided with hole and is movably installed with crank, by rotating crank
The platen 18 of locking pin 17 can be controlled, and to the compression degree of two swing pieces, after the degree of compression improves, two swing pieces are
It is locked, axis 13 of shaping at this time is constrained to automatically adjust and can not be moved in flat hole 15, so as to fulfill to backrest 2 and leg support 3
Positioning can lock tilting seat after arbitrary swing, simple to operate.
It using the locking mechanism of this implementation, can not only realize that backrest 2 and leg support 3 link, can also simplify existing at present
The structure of tilting seat, without structures such as cylinders, the advantages of reaching the cost for reducing rumble seat.
Embodiment 2：On the basis of embodiment 1, by interlocking bar 8 be divided to it is independent for two sections divide bar, one of them divides bar
End is fixed with length adjustment casing 19, another divides bar to penetrate in the length adjustment casing 19, and in length adjustment casing 19
Port is provided with lock-screw 20.Can control be reached by the degree that interlocking bar 8 is controlled to stretch in length adjustment casing 19
The purpose of 8 length of interlocking bar.Both so as to when 3 Synchronization Control of backrest 2 and leg support is carried out, keep with different angles
Degree carrys out synchronizing moving.
