Description
Technical field
The utility model relates to a kind of seat, and what relate in particular to a kind of formula multifunction seat of freely lying stops Shuan Xi mechanism.
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 by position change become the formula of freely lying multifunction seat that a kind of frame of freely lying uses stop Shuan Xi mechanism.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the formula of freely lying multifunction seat stop Shuan Xi mechanism, comprise angle adjustment lever, extension rod, support bar, horizon bar, the first baffle plate and second baffle, 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 set on positioning sleeve on extension rod, positioning sleeve inwall is provided with internal thread, angle adjustment lever front end is axially arranged with groove hole, one section in groove hole of angle adjustment lever is pyramidal structure, this pyramidal structure surface is provided with external screw thread, and positioning sleeve is threaded with angle adjustment lever front end and fastening extension rod.
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.
Adopt technique scheme, the formula of freely lying multifunction seat also comprises the seat body consisting of bracing frame, seat board, backrest and handrail, and angle adjustment rod rear end is hinged on seat board lower front side.In addition, at the first baffle plate and second baffle, be coated with respectively elastic insert outward.
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 unscrew positioning sleeve, draw forward or promote backward extension rod, guide pad moves axially along gathering sill, can guarantee like this that extension rod can only move axially does not rotate, adjust after the front and back position of the first baffle plate and second baffle, screwed in place cover again, positioning sleeve compressing angle adjustment lever front end, the reduced width in groove hole, so just extension rod and angle adjustment lever are fastened as a whole, people are sitting on seat board, two knees are just stopped 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 angle adjustment lever, and upper rack posts, lower fulcrum bar and angle adjustment lever 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.
