Description
Technical field
The utility model relates to a kind of seat, relates in particular to a kind of anti-waist and damages multifunction seat.
Background technology
People are when using chair, and due to the difference of the different and individual build of chair ergonomics design, identical one has different use impressions chair to different people.After visiting and investigating, find a very interesting problem, people are when using chair, and the office swivel chair of current trend especially always automaticly down " slips " from chair, is easy to so just waist " unsettled ".Because a lot of swivel chairs have the function of layback, fixing and have certain elasticity before and after chair.People are delithted with when loosening to layback, remove to rock seat, thereby can make buttocks push away forward, cause waist unsettled.And in the situation that having bustle, also can cause unsettled.Reason due to trousers simultaneously while pushing away before buttocks also can cause certain pressure to male external genital organs.If do not adjust and take attitude in time, after sitting, can just to health, cause various discomforts.After visiting and investigating, find that equally people like leg to stick up at the frame of freely the lying low stool of the leg rest (son) upper when rest, existing a lot of chairs all directly do not provide this function, have because structural design defect not is very comfortable while causing using yet.
Utility model content
The utility model is in order to solve weak point of the prior art, provide a kind of reasonable in design, simple in structure, can prevent from " slipping " under health and can change and become the anti-waist that a kind of frame of freely lying uses and damage multifunction seat by position.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: anti-waist damages multifunction seat, comprise by bracing frame, seat board, the seat body that backrest and handrail form, described seat body front side is provided with and stops Shuan Xi mechanism, the described Shuan Xi of stopping mechanism comprises angle adjustment lever, extension rod, support bar, horizon bar, the first baffle plate and second baffle, angle adjustment rod rear end is hinged on seat board lower front side, angle adjustment lever is hollow tubular structure, extension rod is plugged in angle adjustment lever by angle adjustment lever front end, between angle adjustment lever inwall and extension rod, be provided with axial stretching location structure, horizon bar middle part is hinged on extension rod front end, the first baffle plate and second baffle are symmetrical and be located at respectively on horizon bar about horizon bar, support bar between the first baffle plate and second baffle and post upper be hinged on horizon bar,
Described axial stretching location structure comprises two gathering sills axially offering along angle adjustment lever inwall, is located at extension rod outer wall the guide pad that can slide along gathering sill and is located at the spring button in angle adjustment lever, extension rod outer wall is evenly provided with at least two grooves vertically, distance between adjacent two grooves is 2mm, and the inner of spring button is radially pressed in groove through angle adjustment lever top.
Described support bar comprises upper rack posts and lower fulcrum bar, and upper rack posts top and bottom are hinged with horizon bar and lower fulcrum bar respectively, and lower fulcrum bar lower end is provided with support rubber cushion.
Described the first baffle plate and second baffle are coated with respectively elastic insert outward.
Adopt technique scheme, main design thought of the present utility model is used the first baffle plate and second baffle to block two knees exactly, thereby stops buttocks reach to stop health to glide, thereby prevents that waist is unsettled, prevention waist injury.Meanwhile, the first baffle plate after above turning over and second baffle can ensure the weight of enough strength support people's shanks under support bar contacts to earth support, reach the object that changes the frame of freely lying into.
When needs stop two knee, angle adjustment lever is overturn forward, the first baffle plate and second baffle keep vertical state, different people is according to actual conditions, can be by pulling spring button, make a groove of the inner disengaging of spring button, draw forward again or promote backward extension rod, guide pad moves axially along gathering sill, guaranteeing that extension rod can only move axially does not rotate, trip spring button, the inner of spring button and another groove top interference fit, adjust the correct position of the first baffle plate and second baffle like this.People are sitting on seat board, and two knees just stop by the first baffle plate and second baffle, smooth and make waist " unsettled " with regard to having avoided body forward like this.
When the first baffle plate and second baffle are upwards turned over to level, upper rack posts and lower fulcrum bar are launched respectively to support on the ground, regulate again extension rod that extension rod is pulled out to correct position simultaneously, sit in like this on seat board two shanks are placed on the first baffle plate and second baffle, the utility model can change the frame of freely lying into be used.
When not in use, extension rod is all inserted in angular adjustment bar, and upper rack posts, lower fulcrum bar and angular adjustment bar are folded into seat board below.
Elastic insert provides good comfortableness for stopping two knees and supporting two shanks, and takes into account elasticity and gas permeability.
In sum, the utility model is simple in structure, reasonable in design, easy to use, installs additional and stop Shuan Xi mechanism under existing seat, thereby realize, prevents that waist from damaging and providing the demand of the integrated frame of freely lying.
