Abstract
The utility model relates to an accessory of chair especially relates to a coupling mechanism for back and seat. A coupling mechanism for back and seat, includes tray and the swing joint back of the chair mount on the tray, be equipped with logical groove on the tray, logical inslot holds to be had the connecting rod of back of the chair mount, be equipped with locking device on the outer wall of logical groove. The utility model discloses the structure is ingenious to level, perpendicular distance's between back and the seat regulation has been realized to one set of device, and, because its mechanism's characteristic, can use the working of plastics to substitute originally the metalwork in the similar products, very big the cost is reduced totally.
Description
Technical field
This utility model relates to a kind of accessory for chair, particularly relates to a kind of bindiny mechanism for back and seat.
Background technology
The chair sold in the market mostly is the chair of adjustable back.The bindiny mechanism of its seat and backrest is divided into two parts, and a part is flexibly connected with seat, regulates the horizontal range of backrest and seat, and another part is connected with movable backrest, adjusts the vertical dimension of backrest and seat.This kind of structure is suitable for the needs of different consumer, is subject to the welcome in market, but this kind of structure relative complex, it is necessary to two set carriage and locking devices, relatively costly, cheap chair is difficult to apply.So how to make one and can reduce cost, apply to the bindiny mechanism for back and seat on cheap chair, the problem that inventor to solve just.
Summary of the invention
This utility model solves the bindiny mechanism's structure relative complex in prior art for back and seat, relatively costly problem, it is provided that a kind of bindiny mechanism that cheap chair can be made also to have backrest scalable function.
Its concrete technical scheme is: a kind of bindiny mechanism for back and seat, including pallet and be movably connected in the chair back fixed mount on pallet, described pallet is provided with groove, and in described groove, the connecting rod of chair back fixed mount is stated in accommodation to some extent, and described groove outer wall is provided with locking device.Owing to groove entirety wraps up connecting rod, this structure is higher compared to the structural strength of prior art own, can directly use moulding to complete, it is not necessary to metalwork provides higher intensity, and cost is greatly lowered.
As preferably, the angle of described groove inwall and connecting rod and horizontal plane is 18 ° ~ 35 °.There is the groove of certain angle, in the process that described back rest slides, i.e. the horizontal range of adjustable backrest, the also vertical dimension of adjustable backrest, realize two functions with a set of mechanism.
As preferably, described connecting rod offering holding tank, described holding tank width is not less than the width of the gas bar spring matched with pallet.Holding tank is avoided being in that the activity space that connecting rod lived by the gas pole spacing that pallet connects.
As preferably, described locking device is screw rod and passes groove and mate with the nut preset on groove another side inwall.This simple in construction.
This utility model structure is ingenious, achieves the adjustment of level between back and seat, vertical dimension with set of device, and, due to its mechanism characteristics, working of plastics can be used completely to substitute the metalwork in script similar products, greatly reduce cost.
