Abstract
The invention discloses a chair supporting structure, which comprises a supporting rod and a fixing seat, wherein one end of the supporting rod is provided with a limit groove, while the other end is provided with a fixing hole which can fix the supporting rod on a chair. The fixing seat can be arranged on a leaning piece which can be used as a back cushion, a head cushion or an elbow cushion in an integrated forming mode, and the inside of the fixing seat is provided with an accommodating cavity. One end of the supporting rod provided with the limit groove can be inserted in the accommodating cavity, and the upper wall and the lower wall of the accommodating cavity are provided with a plurality of mutually opposite convex ribs respectively. The fixing seat is provided with a threaded hole and a through hole which are opposite, and the threaded hole and the through hole can be opposite to the limit groove so as to utilize threaded rod threaded locking to ensure that the convex ribs tighten the supporting rod, and fix the supporting rod on the leaning piece. Gaps formed between the convex ribs provide a deformation margin for the fixing seat when the threaded locking tightens so as to prevent deforming or cracking conditions occurring under the tightening force of the locking.
Description
Technical field
The present invention relates to a kind of chair supporting structure, relate in particular to a kind of aesthetic in appearance and can bear lock spiral shell time compressing strength and indeformable chair supporting structure.
Background technology
General office seat mainly comprises seat support, the chair back and the bracing frame that links the seat support and the chair back, the end that bracing frame links the chair back offers microscler locking hole, the holder of screw is set behind the chair back, holder is made of base and the covering that is covered on the base, and in hide and base between form can ccontaining bracing frame containing cavity, hide simultaneously and offer stopper slot, and stopper slot can be corresponding with microscler locking hole, be inserted in the containing cavity and when adjusting the fixed position of the chair back for bracing frame, can utilize screw rod to see through stopper slot in regular turn, screw on microscler locking hole and the holder, be fixed in the holder and bracing frame is locked spiral shell, reach and to adjust chair back height and simultaneously can coat bracing frame in the hope of purpose attractive in appearance by hiding again.
In the right aforementioned structure, because holder is the base that can separate and make up and hides the separate type that is constituted, so the intensity and the tolerance that hide are relatively poor, easily when the lock spiral shell, because of bearing the strength torsional deformation of lock spiral shell compressing, even the possibility of damage rupture arranged, and the covering inner top surface that section is " ㄇ " type is the structure on plane, also can't provide distortion nargin, overall durability is not good, and the stopper slot of offering on hiding is excessive, when it is covered on base, still can't cover bracing frame and part not attractive in appearance fully, be difficult to reach the demand of beautifying outward appearance.
Summary of the invention
For improving the inaesthetic shortcoming of supporting construction in the prior art, and solve the problem of torsional deformation due to the lock spiral shell is fixedly the time, the invention provides a kind of aesthetic in appearance and can bear lock spiral shell time compressing strength and indeformable chair supporting structure, make fixedly seat support of structure that the user can be by durability, the while can reach demand attractive in appearance again.
For reaching above-mentioned purpose, the invention provides a kind of chair supporting structure, comprising:
One support bar, its two ends offer at least one slotted eye; And
One holder, it is arranged at one and leans on the part, one containing cavity is set in this holder to be embedded in the containing cavity for described support bar, offer the corresponding fin of multiple tracks respectively on two walls that contact with support bar in the described containing cavity, and on the fin of holder, be provided with relative locating hole for being spirally connected with described support bar, and make the crooked and relative packing support bar of described fin simultaneously by being spirally connected, and being fixed in, it leans on the part.
The slotted eye that described support rod end is offered can be stopper slot or fixing hole, with seat support on fixing hole or embed in the containing cavity of described holder after the location that is spirally connected.
Offer the holddown groove of at least one indent on the pole face of the fin bearing of described support bar relative fixed seat, and on the fin position of the holder of its relative clamping, convex with at least more than one replace the piece body, embed location in the holddown groove during for its clamping support bar.
The locating hole of described holder is screw or through hole.
The multiple tracks fin of offering in the containing cavity of described holder, the space of Xing Chenging provides the distortion nargin of fixed seat structure when the screw lock packing therebetween.
One-body molded being arranged at of described holder leans on the part.
Described dependence part is a back cushion.
Described dependence part is a head cushion.
Described dependence part is a proficiency armrest pad.
Compare with the fixed seat structure of separate type covering of the prior art with base, the beneficial effect of chair supporting structure provided by the invention is: described fin and integrated design significantly promote the intensity and the tolerance of holder, and the deformation nargin the when space between between fin provides holder to bear lock spiral shell packing strength, in case distortion or the generation of damage and crack situation due under lock spiral shell fixed pressure, and then the resistance to pressure and the practicality of promoting holder.The holder of the design of the present invention simultaneously need not be offered the mould that hides with base respectively as prior art during fabrication, saves die sinking cost on the manufacture process.In addition, holder and imperforation hinder stopper slot attractive in appearance greatly, just can adjust to lean on part to suitable height and position place, therefore can cover support bar fully and reach part not attractive in appearance, make the chair overall appearance can meet demand attractive in appearance; The while holder can be installed in chair and need adjust on the dependence parts such as back cushion, head cushion or elbow back cushion of height or length, with the comfort level of enhancement chair, and meets the wide and practical demand of application.
