Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
This back seat backrest of the present invention turns down experimental rig, as shown in fig. 1, including is set on backrest 1 and solves
The tripper 3 of lock chair back 1,1 lower end of backrest by be hingedly connected on test platform (test platform in figure not
Illustrate), the side of backrest 1, which is equipped with, to be connected on the skeleton of backrest 1, and pushes backrest 1 hinged around lower end
Locate the fold cylinder 2 of fold.Back seat backrest is equipped with the lockable mechanism of controllable folding in design, by pulling the lock
The unlock knob unlock backrest of locking mechanism, realizes the fold of control backrest.When test, backrest is mounted on examination
It tests on platform, tripper is connected on backrest 1, lockable mechanism unlock is controlled by manipulation tripper 3, thus real
The fold unlock of existing back seat backrest, then the fold cylinder 2 by being connected on backrest frames push backrest to realize it
Fold motion process between most preceding and rearmost position.Backrest, which is controlled, by this experimental rig carries out multiple fold
Journey analyzes the fatigue durability of backrest to observe the state after backrest test.
In the present invention, tripper 3 includes solution lock cylinder 31, solves lock cylinder 31 by drag wire and is connected to backrest 1
Unlock knob on.Starting solution lock cylinder, the flexible rod end of solution lock cylinder 31 retract, and pull unlock knob to realize by drag wire
Unlock.In the present invention, solution lock cylinder 31 is connected in support plate 32, and support plate 32 is connected to by connecting screw 33 set on seat
In the headrest mounting hole of 1 upper end of backrest.As shown in fig. 1, such tripper structure is simple, at low cost, rationally cleverly sharp
Installation positioning is carried out with the structure of backrest itself, convenient for test mounting arrangements, and operational stability is good.
In the present invention, solution lock cylinder 31 passes through the cylinder mounting holes being set in support plate 32, and the top of support plate 32 is under
Side is respectively equipped with the fixture nut that cooperation is tightened on the cylinder body wall surface of solution lock cylinder 31, real by fixture nut arranged up and down
Now being connected and fixed to solution lock cylinder 31.Preferred in the present invention, cylinder mounting holes are to arrange along backrest width direction
Kidney slot is convenient for test operation, so that the experimental rig applicability is more to adapt to the backrest of matching different specification size
It is good.
In the present invention, set that there are two be each passed through the screw rod mounting hole of connecting screw 33 in support plate 32.Two screw rod peaces
It fills in hole and arranges that the screw rod mounting hole of side is the kidney slot arranged along 1 width direction of backrest far from solution lock cylinder 31.Such as
Shown in Fig. 1, it is attached fixation using two connecting screws 33, connective stability is good；It will be wherein far from solution 31 cloth of lock cylinder
The screw rod mounting hole for setting side is set as kidney slot, cooperates the cylinder mounting holes of kidney-shaped structure, to further increase it to two sides
Adjusting range meets the test demand of more excessively a backrests, has preferable versatility.Connecting screw 33 is by being set to it
On locking nut be located and be locked in support plate 32.
