Description

A kind of inclination controller of office chair

Technical field

The present invention relates to office chair field, more particularly to the improvement of the device for the regulation of wherein reclining dynamics.

Background technology

The mode of prior art generally use regulation spring-compressed degree when the reclining dynamics to office chair is adjusted Operated, representative a entitled " the adjustable seat bottom of reclining power announced such as State Bureau on November 7th, 2012 Disk ", Application No. " 200910249634.9 " Chinese invention patent shown in, in the case propose by worm drive worm gear and then Turn regulating bolt compression spring so that the technical scheme changed occurs in the compression degree of spring.

Meanwhile wherein to cause seat to switch between adjustable inclination and not adjustable inclination, the case is set between mid-game and deep bid Put complex latch-up structure, its inevitably have complex operation, operation difficulty big in use and The defects of stability is poor, service life is short, the operation ease overall to office chair bring strong influence.

The content of the invention

The present invention is directed to problem above, it is proposed that a kind of delicate structure, easy to operate, operation difficulty be small and structural stability The inclination controller of office chair high, operation ease is good.

The technical scheme is that：Including upper hinged seat, screw rod, spring, spring base, lower hinged seat, locking swing rod and Locking column, the upper hinged seat are hinged on the lower section of the chair back of office chair, and the lower hinged seat is hinged on the base of office chair, The top of the screw rod, which is located in hinged seat and slided with upper hinged seat, to be connected, the bottom of the screw rod and lower hinged seat It is fixedly connected；The spring base is threadedly attached on screw rod, the spring empty set outside screw rod and be against hinged seat and Between spring base；

The locking column is located in hinged seat and fitted with the top of screw rod, and internal diameter is offered in the locking column not Less than the sliding eye of outer screw diameter, the spacing in the axle center of the sliding eye and the axle center of locking column is L, the axle center of the screw rod with The spacing in the axle center of locking column is H, L=H；The locking swing rod is fixedly connected on locking column and extend out to outside hinged seat.

The top of the upper hinged seat offers the stopper slot perpendicular to locking column axial direction, and the locking swing rod is slidably connected In stopper slot, and if only if locking swing rod is when be in side extreme position, sliding eye and the screw coaxial heart.

The support stretched out outside spring, the one end of the support away from screw rod are also fixedly connected with the outer wall of the screw rod Be fixedly connected and be parallel to anti-error bar of the screw shaft to setting, it is described locking swing rod on offer be adapted to anti-error bar it is anti-error Hole, and if only if when screw rod stretches into sliding eye, and anti-error bar stretches into anti-error hole.

When the present invention is specifically used, pull locking swing rod locking column can be driven to be rotated around Pivot Point Center, until sliding eye When turning to screw coaxial heart shaped state, office chair switches to adjustable inclination state；And work as effect of the chair back in spring of office chair Lower reset, when screw rod is slided out to outside sliding eye, rotation lock fixed pendulum bar may be such that sliding eye is different from screw rod axle center again, screw rod Locked capital is lived, and office chair switches to not adjustable inclination state.

In summary, operating personnel only need in the case of no pressure spin locking swing rod, you can realize office chair can Switching easily and fast between reclining state and not adjustable inclination state, due to locking swing rod and locking column in its handoff procedure Upper no pressure, therefore, operating personnel only need less power to can be achieved to operate the convenient of locking swing rod, have knot on the whole The advantages of structure is exquisite, easy to operate, operation difficulty is small and operation ease is good.

Embodiment

The present invention as shown in figures 1-8, including upper hinged seat 1, screw rod 2, spring 3, spring base 4, lower hinged seat 5, locking pendulum Bar 6 and locking column 7, the upper hinged seat 1 are hinged on the lower section of the chair back of office chair, and the lower hinged seat 5 is hinged on office chair Base on, the top of the screw rod 2 be located in hinged seat 1 and with upper hinged seat 1 slide is connected, the bottom of the screw rod 2 End is fixedly connected with lower hinged seat 5；The spring base 4 is threadedly attached on screw rod 2, and the empty set of spring 3 is in screw rod 2 Outside and it is against between hinged seat 1 and spring base 4；

The locking column 7 is located in hinged seat 1 and fitted with the top of screw rod 2, is offered in the locking column 7 interior Footpath is not less than the sliding eye 70 of the external diameter of screw rod 2, and the spacing in the axle center of the sliding eye 70 and the axle center of locking column is L, the spiral shell The spacing in the axle center of bar 2 and the axle center of locking column is H, L=H；The locking swing rod 6 is fixedly connected on locking column and stretched out Outside supreme hinged seat 1.So, locking swing rod is pulled locking column to be driven to be rotated around Pivot Point Center, until sliding eye turns to During with screw coaxial heart shaped state, office chair switches to adjustable inclination state；And the chair back for working as office chair resets under the action of the spring, When screw rod is slided out to outside sliding eye, rotation lock fixed pendulum bar may be such that sliding eye is different from screw rod axle center again, and screw rod is locked Capital is lived, and office chair switches to not adjustable inclination state.

The top of the upper hinged seat 1 offers the stopper slot perpendicular to the axial direction of locking column 7, and the locking swing rod 6 slides It is connected in stopper slot, when being in side extreme position, sliding eye 70 and screw rod 2 are concentric for and if only if locking swing rod 6.This Sample, operating personnel will lock swing rod when being pulled to side extreme position, you can determine sliding eye and the screw coaxial heart, office chair is cut It is changed to adjustable inclination state；And when locking swing rod is pulled into opposite side extreme position, you can determine that sliding eye is not coaxial with screw rod The heart, office chair switch to not adjustable inclination state；So as to further improve the operation ease of this case on the whole, this case is reduced Operation difficulty.

The support 20 stretched out outside spring is also fixedly connected with the outer wall of the screw rod 2, the support 20 is away from screw rod 2 One end be fixedly connected and be parallel to the axially arranged anti-error bar 21 of screw rod 2, offered and anti-error bar 21 on the locking swing rod 6 The anti-error hole of adaptation, and if only if when screw rod 2 stretches into sliding eye 70, and anti-error bar 21 stretches into anti-error hole.So, when office chair switches For adjustable inclination state and reclining is carried out in use, anti-error bar will be stretched into anti-error hole so that people can intuitively, clearly judge Locking swing rod can not now be pulled；And when office chair no longer needs reclining, by anti-error bar can intuitively, clearly judge spiral shell Whether bar is fully slid out to outside sliding eye.So as to effectively prevent when screw rod is not fully slid out to outside sliding eye, because of mistake Early operation locking swing rod, and caused by lock swing rod, screw rod even inclination controller and the problem of damage integrally occur, enter one Step reduces the operation difficulty of this case, and ensure that the operational stability and use reliability of this case.
