Abstract
The utility model provides a chair seat rotation reset device, which is characterized in that the utility model comprises a bearing capable of resetting and a rectangular minor shaft, wherein the resettable bearing comprises a rotary table, a shaft sleeve, a torsional spring and a mandrel. The shaft sleeve is sheathed on a hollow shaft of the rotary table, the torsional spring is arranged between the shaft sleeve and the hollow shaft, wherein one end of the torsional spring is fixed on the rotary table, the other end of the torsional spring is fixed on the shaft sleeve. The mandrel is arranged inside the hollow shaft, one end of the mandrel is provided with a flange which is connected with the shaft sleeve via screw bolts and screw nuts. The center of the mandrel is provided with a screwed hole, a screw which prevents the rotary table from falling off is connected with the screw hole through the rotary table, further a square trough cooperated with the minor shaft is provided on the outer side of the rotary table. When using, the resettable bearing is arranged on the chair legs, and the minor shaft is arranged on the chair seat. The utility model uses the torsion force produced by the torsional spring to lead to the resetting of the chair seat to the firmly-positioned state. The utility model has the advantages that the chair seat is easy in assemblage, the cleaning is convenient without producing great impact noise and the like, the utility model is applicable for miscellaneous the chairs in assembly hall or in theaters.
Description
Technical field
The utility model relates to furniture part, and particularly a kind of seat support rotates returning device, is fit to assembly chair and adopts.
Background technology
As everyone knows, assembly chair be a kind of behind people's egress of chair its seat support can erect the chair of putting automatically.In order to realize this purpose, the method that prior art is taked is to establish a rotating shaft in the seat support bottom surface, and this rotating shaft is supported with two chair pin, and allows the seat support weight at rotating shaft rear portion greater than the weight of front portion.Behind people's egress of chair, chair base rear end descends naturally and makes that seat support is perpendicular to be put.This structure has simple, practical advantage.Yet weak point is that seat support is difficult to take out cleaning, and upset the time can produce bigger impact sound.
Summary of the invention
The purpose of this utility model is that a kind of seat support that makes takes out cleaning easily, and the seat support that produces big impact sound in the time of can not making the seat support return again rotates returning device.
Task of the present utility model realizes by this way: this seat support rotates returning device and is made of can reset bearing and a rectangle minor axis that cooperates with it, this bearing that can reset is by rotating disk, axle sleeve, torsionspring and mandrel are formed, axle sleeve is socketed on the hollow shaft of rotating disk, torsionspring places between axle sleeve and the hollow shaft, the one end is fixed on the rotating disk, the other end is fixed on the axle sleeve, mandrel places in the hollow shaft, its end is provided with a flange, link together by screw bolt and nut and axle sleeve, have screwed hole at the mandrel center, the screw that anti-rotation disks comes off passes rotating disk and is connected with screwed hole, is provided with a square groove that cooperates with minor axis in the outside of rotating disk.
The purpose of this utility model also can take following measure to realize: symmetry has two arc stopper slots on the contact-making surface of axle sleeve and rotating disk, on the rotating disk of correspondence, be provided with the slide block that cooperates with stopper slot, so that the rotational angle of control rotating disk, this angle is suitable with 80-90 ° generally.
The purpose of this utility model also can realize by following measure: respectively be provided with a trip bolt in the rotating disk of square groove both sides, so that minor axis is fastening, prevent slippage, be beneficial to dismounting again.
Operation principle of the present utility model is such: during use axle sleeve of the present utility model partly is socketed in the dead eye of chair pin inboard, allow rotating disk expose to chair pin inboard, cooperate by the bolt in nut and the axle sleeve again to make it to be connected, prevent that axle sleeve from rotating with the chair instep.Allow the square groove of rotating disk vertically be provided with during assembling, then that the seat support both sides are fixing short sleeve fastening just can it by trip bolt to square groove again.When people pulled down seat support and are sitting on the seat support, minor axis drove rotating disk by square groove and rotates around mandrel.Because axle sleeve is fixed, torsionspring is produced reverse, store a twisting resistance, when people left seat support, this twisting resistance just was returned to the origin-location with seat support, thereby had realized that seat support can automatically reset requirement.In addition, because the utility model has been offered stopper slot on axle sleeve, established slide block on rotating disk, rotational angle is restricted, can not bump with backrest when seat support rotates produces excessive strike note.Therefore, compared with the prior art, the utlity model has novel structure, seat support loads and unloads easily, can not produce excessive advantages such as strike note when cleaning convenience and use.
