Abstract
The utility model provides a rotation device of chair base having damper. The device comprises a spring gyrator, a chair base support and a chair base spindle. It is characterized in that the model also has a disk damper which is composed by bottom plates of an outer disk and an inner disk inside the outer disk. The outer disk and the inner disk are equipped with at least two damping rings separated from each other respectively. Damping grease is injected in the clearance. The outer disk is equipped on the bottom plate. On the end surface of the outer disk is a through hole matching with the central spindle of the inner disk. On the base plate is a through hole matching with the chair base spindle. The whole disk damper is installed on the chair base support via the screw through the assembly hole on the outer disk. The square spindle section of the chair base spindle is arranged inside the square hole in the central spindle of the inner disk. This utility model utilizes the mutual rotation between the inner and outer disk damping rings of the disk dampers to slow down the rotation under the function of the viscosity of the damping grease to reduce the rotating speed of the spring gyrator and realize the slow rotation of the chair base. The model overcomes the defect of the current chair base gyrator which has big collision noise due to failure of slow rotation.
Description
Affiliated technical field
The utility model relates to furniture part, and particularly a kind of seat support slewing equipment with damper is fit to employings such as assembly chair, pupil chair.
Background technology
At present many church chairs and pupil chair all are provided with the rotating resilient mounting of seat support, so that seat support will turn round immediately when people leave seat, abdicate more space and walk about for people.In prior art, generally, weighting material makes seat support revolution by being set in seat support rotating shaft rear end, have also that to be provided with the spring be that the slewing equipment of power is realized on the seat support axle.Rotate acceleration yet can have no the ground of obstruction when adopting any slewing equipment all to have the seat support revolution, produce more strike note on bump backrest or the locating piece.People have cognition, and one to finishing the meeting or finishing class, and this strike note just rises and falls each other, and big the making us of its noise is fed up with, and also is a kind of performance of civilization inadequately, and this is the prior art weak point just.
Summary of the invention
The purpose of this utility model is to provide a kind of seat support slewing equipment with damper, and this seat support slewing equipment can overcome the defective of existing seat support slewing equipment effectively, allows seat support slowly turn round, and has significantly reduced impact sound.
Above-mentioned task realizes by this way: a kind of seat support slewing equipment with damper, include the spring gyrator, chair base supporting and seat support axle, it is characterized in that disk damping device in addition, described disk damping device is by outer disc, place interior disk and base plate composition onesize in the outer disc with its inner chamber, be provided with the central shaft that a center has square through hole in interior disc centre, outer disc underrun screw is anchored on the base plate, have the through hole that cooperates with interior disc centre axle in the outer disc outer face, have the through hole that cooperates with the seat support axle at the base plate center, in involutory outer disc and interior disk inner chamber, be provided with the damping ring that is not less than 2 spaces at least respectively separately, its gap is 0.2～0.5 millimeter, in the gap, inject damping grease, whole disk damping device is placed on the chair base supporting by screw with the pilot hole on the outer disc bottom surface, and square through hole of disk is installed on the square shaft section of seat support axle the inner in it.
The utility model is like this work: earlier the seat support slewing equipment is installed on the seat support by chair base supporting during use, and then the seat support axle is placed on the bogie side frame of seat and just can.When seat support upset was up to the standard the position, the spring slewing equipment had increased the torsion of spring with the rotation of seat support, in case when people left seat support, this torsion made the seat support revolution.Meanwhile the outer disc of disk damping device also rotates with chair base supporting.Because square through hole of disk is placed on the square shaft section of seat support axle in it, the seat support axle is motionless, and therefore interior disk does not change yet, and has only outer disc to rotate with respect to interior disk.Owing to filled with damping grease between the damping ring of outer disc and interior disk, its viscous effect makes the outer disc can not very fast rotation, thereby chair base supporting and whole seat support are slowly turned round, and has realized slow rotating requirement, has overcome the defective of prior art effectively.
Description of drawings
Fig. 1 is the partial sectional view of a kind of concrete structure of seat support slewing equipment of band damper.
Fig. 2 is along the profile of A-A among Fig. 1.
Fig. 3 be among Fig. 1 B to amplification view.
Fig. 4 is along the local amplification view of C-C line among Fig. 3.
The specific embodiment
With reference to Fig. 1, a kind of seat support slewing equipment with damper comprises spring gyrator 1, chair base supporting 2 and seat support axle 3.Its improvements also increase a disk damping device 4, and this disk damping device 4 is made up of outer disc 5, interior disk 6 and base plate 7.Interior disk 6 places in the outer disc 5, and its size is consistent with outer disc 5 inner chambers.In interior disk 6, be provided with the central shaft 9 that a center has square through hole 8.As shown in Figure 3 and Figure 4, outer disc 5 underrun screws are placed on the base plate 7, have the through hole 10 that cooperates with interior disk 6 central shafts 9 in outer disc 5 outer ends, have the through hole 11 that cooperates with seat support axle 3 circular shaft sections at base plate 7 centers.As shown in Figure 2, be respectively equipped with the damping ring 12 and 13 of 3 spaces separately in the inner chamber of involutory interior disk 6 and outer disc 5, each damping ring 12 and 13 gap are 0.3 millimeter, inject damping grease 14 within it.This damping grease 14 adopts the damping grease of selling on the market just can.Whole disk damping device 4 is placed on the chair base supporting 2 by screw 15 with the pilot hole on outer disc 5 bottom surfaces, and square through hole 8 of disk 6 is installed on the square shaft section 16 of seat support axle 3 the inners in it.Outer disc (5) and interior disk (6) form with plastics die casting.
