Automatic unlocking is realized in cooperation with chuck, is additionally provided with dynamic clamping head and quiet clamping head 52 between the lock part 51 and adjustment seat 41.Utilize card
Locking is realized in cooperation between disk and card convex 51a, in chuck motion (movement refers to the movement when external force rotates knob), is led to
Crossing jack-up card convex makes its cooperation failure play the role of adjusting, after external force removes, makes card convex again by dynamic clamping head and quiet clamping head 52
Cooperate with chuck, realizes automatically lock.
In the present solution, being equipped with the latch 413a of multiple protrusions and multiple cards on the outer peripheral surface of the chuck 413
The same side tooth 413a is inclined-plane, and another side is vertical plane, and the card convex 51a of the lock part 51 is the card with the chuck
The reversed latch of tooth 413a engagement.The structure matched using inclined-plane with inclined-plane, when along bevel direction rotating chuck, on inclined-plane
Mating reaction under, touching moves upwards lock part, makes that its reversed latch is detached from and latch engages, to realize automatic clamping
Lock, and certain anti-loosening effect is also acted as by the way that dynamic clamping head and quiet clamping head 52 is arranged.
In addition, lock part 51 is equipped with 2 reversed latches engaged with chuck in this programme, it is more steady that clamping can be played
It is fixed, further anti-loosening effect.
In addition, being additionally provided with the unlocking portion 51b of protrusion on the lock part 51, it is additionally provided with described in confession in the adjustment seat 41
Unlocking portion 51b extend out to the notch outside adjustment seat 41, can drive the lock part 51 is mobile to realize hand by the unlocking portion 51b
Dynamic unlock.User can operate on the outside the mobile lock part by manpower, by the unlocking portion of stretching by lock part up
It beats, makes the cooperation of reversed latch disengaging chuck thereon manually, bandage rotates backward knob under the elasticity of itself, so that tying up
Band can automatically reset, so as to quickly adjust back rest to the position of maximum angle.
The utility model provide backrest can step-less adjustment angle perambulator, back rest is arranged to be hinged on seat frame
On, being equivalent to back rest can arbitrarily swing with respect to seat frame along hinged place, then by being used to support and fixing the back rest
Regulating device realize that back rest any angle in adjustable extent is adjusted to realize the step-less adjustment of back rest, thus
More it is able to satisfy the demand of user.
It is the one or more embodiments provided in conjunction with particular content as described above, does not assert the tool of the utility model
Body implementation is only limited to these instructions.It is all approximate with the method for the utility model, structure etc., identical or practical new for this
It makes several technologies under type concept thereof to deduce, or replacement all should be considered as the protection scope of the utility model.
