Using the above structure, leaning against rotation seat can rotate the utility model relative to seat firm banking, work as to realize
In the case that seat remains stationary, leaning against can still rotate to it, thus the utility model be highly suitable for it is certain special
Usage scenario (such as dentist's office, body correction mechanism) can still make seat in the immovable situation in user's sitting direction
It leans against and rotates forward or backward, thus the dependence direction of changeable user.
A kind of seat back rotational structure as described above, the tripper include the unlock on the holding tank
It pull rod and leans against on rotation seat and set on described along the annular rotation slot of the outside of support rod attachment base setting, the annular
The outer circumferential of rotation slot is equipped with card slot, and one end of the unlock pull rod is articulated on the holding tank and on the unlock pull rod
Matched locking fixture block is clamped with the card slot so that when the locking fixture block and institute equipped with rotation seat is leaned against described in
State when card slot is mutually clamped and to lean against the rotation of rotation seat described in limitation, the middle part of the unlock pull rod and the seat firm banking it
Between be equipped with tension spring so that the locking fixture block holding be mutually clamped with the card slot, it is described unlock pull rod free end be pierced by described in
Holding tank can simultaneously rotate so that the locking fixture block is detached from the card slot and can be in the annular rotation relative to its hinged end
Rotation is so that the rotation seat that leans against can be rotated relative to the seat firm banking on slot.Under the elastic force effect of tension spring,
Locking fixture block keeps the clamped condition with card slot, when rotation unlock pull rod makes the disengaging card slot of locking fixture block thereon and can be in annular
It is rotated on rotation slot, leaning against rotation seat at this time can rotate relative to seat firm banking.
The outer circumferential of a kind of seat back rotational structure as described above, the annular rotation slot is equipped with two cards
Slot, and the position of two card slots is located along the same line so that can be rotated forward or backward by leaning against by 180 °, so that
The changeable state leaned on forward or backward of user.
A kind of seat back rotational structure as described above, described lean against set between rotation seat and the seat firm banking
There is ball so that leaning against rotation seat rotation smoothly and reducing the frictional force for leaning against rotation seat relative to the rotation of seat firm banking when.
A kind of seat back rotational structure as described above, the side of the seat firm banking is equipped with draws for the unlock
Opening bar activity and be pierced by, the holding tank are equipped with the through slot for fixture block activity for the locking and being pierced by.
[Detailed description of the invention]
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, in which:
Fig. 1 is the decomposition texture schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of tripper described in the utility model；
Fig. 3 is structural schematic diagram when the utility model cooperates.
[specific embodiment]
A kind of seat back rotational structure, including the seat firm banking 1 that is fixedly connected with seat bottom (seat plate) and
It is rotatably arranged in the bottom of seat firm banking 1 and what is be fixedly connected with seat back leans against rotation seat 2, lean against rotation seat 2
Middle part be equipped with support rod attachment base 3 for being connected with seat support bar, seat firm banking 1 is equipped with holding tank 11,
Holding tank 11 and lean against between rotation seat 2 be equipped with for locking or unlocking the tripper 4 for leaning against rotation seat 2.
Tripper 4 includes unlock pull rod 41 on the holding tank 11 and set on leaning against on rotation seat 2 and along support rod
The annular rotation slot 42 of the outside setting of attachment base 3, the outer circumferential of annular rotation slot 42 are equipped with two clamp bar slots 45, and two institutes
The position for stating card slot 45 is located along the same line, and one end of unlock pull rod 41 is articulated on holding tank 11 and unlocks on pull rod 41
Equipped with being clamped matched locking fixture block 44 with card slot 45 so that when locking fixture block 44 and 45 phase of card slot through rotation seat 2 is leaned against
Limitation leans against the rotation of rotation seat 2 when clamping, unlock be equipped with tension spring 43 between the middle part and seat firm banking 1 of pull rod 41 so that
Fixture block 44 must be locked to keep being clamped with 45 phase of card slot, the free end of unlock pull rod 41 is pierced by holding tank 11 and can be hinged with respect to it
End rotation is so that locking fixture block 44 is detached from card slot 45 and can rotate on annular rotation slot 42 so that leaning against rotation seat
2 can rotate relative to seat firm banking 1.
Rubbing when smooth and reduction leans against rotation seat 2 relative to the rotation of seat firm banking 1 is rotated to lean against rotation seat 5
Power is wiped, leans against and is equipped with ball 5 between rotation seat 2 and seat firm banking 1.
The side of seat firm banking 1 is equipped with the opening 12 for unlock pull rod 41 activity and being pierced by, and holding tank 11 is equipped with
For the through slot 111 for locking fixture block 44 activity and being pierced by.
When the utility model is used, under the elastic force effect of tension spring 43, the locking holding of fixture block 44 is clamped with 45 phase of card slot
State, leaning against rotation seat 2 at this time can not rotate relative to seat firm banking 1, and user keeps leaning on seat forward or backward
It leans against, card slot 45 and can be rotated on annular rotation slot 42 when rotation unlock pull rod 41 is detached from locking fixture block 44 thereon, this
When lean against rotation seat 2 and can be rotated relative to seat firm banking 1, to realize in the case that seat remains stationary, lean against
It can still rotate to it, and after leaning against rotation seat 2 relative to 180 ° of the rotation of seat firm banking 1, make in the elastic force of tension spring 43
Under, locking fixture block 44 is clamped with another 45 phase of card slot again, so that user is in the immovable situation in sitting direction
Under, the direction of seat leaned against is changed, so that the dependence direction of switching user (becomes leaning on forward from leaning on to lean against backward
By leaning against, or have to lean on to lean against to become leaning on backward forward and lean against).
