Connect；The spring base is threadedly attached on screw rod, and the spring empty set is outside screw rod and is against hinged seat and spring base
Between；
The adjusting part includes adjusting set, and the bottom of the adjusting set is socketed the lower hinged seat and the inwall of adjusting set leads to
Synchronous rotating mechanism is crossed with spring base to be connected.
The spring base includes pedestal, plane bearing and thread plate, and the pedestal is socketed the screw rod and is affixed with spring
Close, the thread plate is threadedly attached on screw rod and positioned at pedestal backwards to the side of spring, the thread plate and adjusting set
It is connected by synchronous rotating mechanism, the plane bearing is socketed the screw rod and is against between pedestal and thread plate.
The synchronous rotating mechanism includes some internal tooths and some external tooths, and the internal tooth is fixedly connected on the outer wall of spring base
On, the external tooth is parallel to the axially arranged of screw rod and is fixedly connected on the inwall of adjusting set, and the external tooth is mutually nibbled with internal tooth
Close.
The synchronous rotating mechanism includes chute and fin, and the chute is opened on the outer wall of spring base, the fin
Parallel to the axially arranged of screw rod and it is fixedly connected on the inwall of adjusting set, the fin is slidably connected in chute.
The adjusting part also includes adjusting rod, adjustment seat and an at least locking rod, is opened on the top surface of the lower hinged seat
Provided with the locking hole being adapted to locking rod, the adjustment seat is socketed the screw rod, the locking rod is fixedly connected in adjustment seat,
And it is slidably connected in locking hole；
Offer on the side surface of the adjusting set and be located in parallel to the axially arranged long stripes through hole of screw rod, the adjusting rod
In the long stripes through hole and its one end is fixedly linked with adjustment seat.
The adjusting rod is telescopic rod.
Present invention eliminates the setting of worm and gear in the prior art so that operating personnel only need turn adjusting set can be
Driving spring seat rotates under the drive of synchronous rotating mechanism, and then is that the reclining dynamics of office chair is made to the compression degree of spring
Conveniently, stably, efficiently adjust, on the whole with delicate structure, driving easy to use, operation format is simple and required
The less advantage of power.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention,
The optimal enforcement that Fig. 2 is the present invention illustrates intention,
Fig. 3 be the use state of the present invention with reference to figure one,
Fig. 4 is the use state of the present invention with reference to figure two；
1 is upper hinged seat in figure, and 2 be screw rod, and 3 be spring, and 40 be pedestal, and 41 be plane bearing, and 42 be thread plate, and 5 be regulation
Component, 50 be adjusting set, and 51 be adjusting rod, and 52 be adjustment seat, and 53 be locking rod, and 500 be long stripes through hole, and 6 be lower hinged seat.
Embodiment
The present invention as Figure 1-4, including upper hinged seat 1, screw rod 2, spring 3, spring base 4, adjusting part 5 and lower be hinged
Seat 6, the upper hinged seat 1 is hinged on the lower section of the chair back of office chair, and the lower hinged seat 6 is hinged on the base of office chair,
The top of the screw rod 2, which is located in hinged seat 1 and slided with upper hinged seat 1, to be connected, the bottom of the screw rod 2 and lower hinge
Joint chair 6 is fixedly connected；The spring base 4 is threadedly attached on screw rod 2, and the empty set of spring 3 is outer in screw rod 2 and is against
Between upper hinged seat 1 and spring base 4；
The adjusting part 5 includes adjusting set 50, and the bottom of the adjusting set 50 is socketed the lower hinged seat 6 and adjusting set 50
Inwall be connected by synchronous rotating mechanism with spring base 4.Eliminate the setting of worm and gear in the prior art so that behaviour
Making personnel only needs turn adjusting set driving spring seat can be rotated under the drive of synchronous rotating mechanism, and then to the compression of spring
Degree be the reclining dynamics of office chair make conveniently, stably, efficient regulation, on the whole with delicate structure, it is easy to use,
The less advantage of the simple and required driving force of operation format.
The spring base 4 includes pedestal 40, plane bearing 41 and thread plate 42, the pedestal 40 be socketed the screw rod 2 and
Being fitted with spring 3, the thread plate 42 is threadedly attached on screw rod 2 and positioned at pedestal 40 backwards to the side of spring 3,
The thread plate 42 is connected with adjusting set 50 by synchronous rotating mechanism, and the plane bearing 41 is socketed the screw rod 2 and supported
Between pedestal 40 and thread plate 42.So, can be in the effect of plane bearing when thread plate rotates under the drive of adjusting set
Under rotary motion is not transferred on pedestal, and only linear motion is transferred on pedestal, occurred so as to effectively prevent spring
The problem of torsion, the morphological stability of spring in use is ensure that, and then ensure that the overall stability in use of this case
And service life.
Representative elaboration is carried out to synchronous rotating mechanism below by two kinds of embodiments：
Embodiment one：The synchronous rotating mechanism includes some internal tooths and some external tooths, and the internal tooth is fixedly connected on spring base
Outer wall on, the external tooth is parallel to the axially arranged of screw rod and is fixedly connected on the inwall of adjusting set, the external tooth and interior
Tooth is meshed.So as to which internal tooth synchronous rotary when external tooth rotates, can be driven, and internal tooth is done axially along a screw relative to external tooth
Relative linear motion；I.e. so that adjusting set rotate when can driving spring seat do straight reciprocating motion along screw rod.
Embodiment two：The synchronous rotating mechanism includes chute and fin, and the chute is opened on the outer wall of spring base,
The fin is parallel to the axially arranged of screw rod and is fixedly connected on the inwall of adjusting set, and the fin is slidably connected at cunning
In groove.So as to when fin rotates, chute synchronous rotary can be driven, and so that chute does axially along a screw straight relative to fin
Line relative motion；I.e. so that adjusting set rotate when can driving spring seat do straight reciprocating motion along screw rod.
The optimal enforcement mode of this case is as shown in Fig. 2 the adjusting part 5 also includes adjusting rod 51, adjustment seat 52 and extremely
Lack a locking rod 53, offer the locking hole being adapted to locking rod on the top surface of the lower hinged seat 6, the adjustment seat 52 is socketed
The screw rod 2, the locking rod 53 are fixedly connected in adjustment seat 52 and are slidably connected in locking hole；The adjusting set 50
Side surface on offer and be located in the strip parallel to the axially arranged long stripes through hole 500 of screw rod, the adjusting rod 51
In shape through hole 500 and its one end is fixedly linked with adjustment seat 52.In use, upper promoting or transferring pole causes locking rod to slide out to locking
Outside hole, you can drive adjusting set to rotate with a smaller power in the presence of lever principle by adjusting rod, set to be regulated
After adjustment, adjusting rod is pushed so that locking rod stretches into locking hole and can be achieved to exchange the stable rotation stop of section set.So, i.e.,
Further can effectively reduce operating personnel adjust office chair reclining dynamics when required application power, have operation difficulty it is low,
Easy to operate and having stable behavior, the characteristics of reliability is high.
The adjusting rod 51 is telescopic rod.So as to reduce further the activity sky needed for adjusting rod in normal use
Between, and in the less women of strength in use, control adjusting rod elongation, then can further reduce and rotate needed for adjusting set
Power so that this case has more preferable operation ease.
