Description
Technical field
The utility model relates to a kind of chair supporting structure, assembly and chair, belongs to the technical field of detachable chair.
Background technology
Traditional seat design prerequisite uses in stationary applica-tions, for firm when using is designed to integrative-structure (or being connected closely by connector), cannot adapt to carry at a distance more, large batch of transport, to move frequently.And along with the variation of people's activity, increasing for the demand can carried with the chair of bulk transport.
For overcoming the above problems, product is in the market made up of chair leg, seat and joint portion, and chair leg perpendicular to seat, and realizes assembling by the compact siro spinning technology of handware and seat; Although product structure is simple, light, but, in use inside configuration does not have horizontal mutual support force, therefore when user's sitting posture produces deflection, easy overturning, and the compact siro spinning technology of hardware-joint of firmly advocating to come from of product, need use instrument when loading and unloading, handling trouble.
For solving the unsteady technical problem of said structure, application number is that patent document discloses of CN201520053879.6 is a kind of detachable, the seat of assembling, comprise the fan-shaped supportive body that two block structures are identical, a support column and one piece of annular seat board of fan, each parts are combined to form functions of seat by locating dowel and bracing frame, but above-mentioned armchair structure is complicated, manufacturing cost is high, carry inconvenience, the more important thing is that in transportation, single part takes up room greatly, single freight volume is little, fixing difficulty, be not easy to large batch of transport, building block is many, dismounting is complicated with assembling.
Utility model content
The utility model will solve the problems of the technologies described above, thus provide a kind of quick detachable, be convenient to tie up the chair supporting structure stacking, be suitable for transport in enormous quantities, this chair supporting structure is not only installed firmly after being installed to chair simultaneously, and a part for the gravity of people or thing can be converted into horizontal mutual support force in use, improve stability.
The technical scheme that the utility model solves the problem is as follows:
A kind of chair supporting structure, for connecting chair leg and chair seat board; This supporting construction is assembled by multiple support unit, and each described support unit at least comprises support portion and chair seat board attachment, and this supporting construction also comprises lower joint portion, for being bound up from bottom by the support portion belonging to different supporting unit.
Preferred as technique scheme, each described support unit includes connection fixed part, and during assembling, the connection fixed part being positioned at different supporting unit is fitted to each other, thus the lower joint portion described in forming.
Preferred as technique scheme, this supporting construction also comprises joint portion, for making the support portion belonging to different supporting unit mutually locate each other from top, and when the chair seat board attachment of this supporting construction is by downward power, mutually support each other.
Preferred as technique scheme, each described support unit includes connection support portion, and during assembling, the connection support portion being positioned at different supporting unit is fitted to each other, thus the upper joint portion described in forming.
Preferred as technique scheme, described support portion is a metal shaft, and described chair seat board attachment is welded with described support portion, and has the chair seat board installing hole run through up and down; Chair seat board attachment local is flat, the flat place, local that described chair seat board installing hole is arranged on chair seat board attachment.
Preferred as technique scheme, during assembling, is positioned at multiple chair seat board attachment places of different supporting unit at grade.
Preferred as technique scheme, described connection fixed part is the sheet metal being fixed in bottom, support portion and having through hole, the rational height being fixed in the sheet metal of different supporting unit differs, therefore multiple support unit makes multiple sheet metal realize folded joining when assembling, thus is convenient to the installation of bolt and nut.
Another object of the present utility model is to provide a kind of chair supporting component, is fixed on above-mentioned chair supporting structure forms by chair leg.
Preferred as technique scheme, described chair leg end is also connected with leg, and described leg is provided with Anti-slip cover.
Another object of the present utility model is to provide a kind of chair, is arranged on above-mentioned chair supporting component forms by chair seat board.
In sum, the utility model has following beneficial effect:
Be not difficult to find out, chair supporting structure provided by the utility model, by the cooperation connection between the connection support portion of multiple support unit and connection fixed part, constitute the upper and lower joint portion of chair supporting structure; After multiple chair leg is attached to multiple support unit respectively, owing to keeping stable needs, chair leg is naturally overhanging, so naturally produce following mechanical relationship: the gravity being applied to chair seat board connecting portion is converted into a downward partical gravity and multiple partical gravity close to level, these partical gravity directions close to level are towards the center of chair supporting structure, and this echoes mutually with the mutual support force of transverse direction said above.That is, by the utility model, make the originally simple annexation relying on the fastening effect of connector, change into, mainly do not rely on the fastening effect of connector and mainly rely on each support unit against a kind of annexation; Therefore, the utility model is when loading and unloading, whether whether support unit connects fasteningly firmly does not have an impact to supporting construction, its benefit brought only needs free-handly just can to complete when loading and unloading, and the cross-brace power that abutment action is brought makes supporting construction more firm, drastically increase firmness when chair uses and stability.
Certainly, for realizing goal of the invention, upper joint portion is nonessential, and it can be substituted by the installation of chair seat board completely; Like this, chair seat board not only serves the effect of supporting user, also serves the horizontal fixation to support unit on top; Now, close to the partical gravity of level, be applied on the connector (as bolt) of vertical state, connector (as bolt) produces horizontal reaction force, keeps balance; This horizontal reaction force is provided by connector (as bolt), can ignore for the Rigidity and strength of connector (as bolt) itself, because power is also not enough to make connector (as bolt) damage, even if connector (as bolt) is made up of wood or plastics for this reason.
