Description
Technical field
The utility model relates to a kind of structure of couch, specifically relates to a kind of couch that is provided with the extensile leg structure of electronic control.
Background technology
The existing couch that is used to take one's seat, it structurally generally is the comfortableness of paying attention to take a seat, promptly on seat, make an issue of more, for then paying attention to and utilize not enough in the chair bottom, so there is the inventor to propose to develop couch bottom function, as Chinese patent notification number CN200973538, November 14 2007 day for announcing, name is called ' the sofa footstool ' the middle proposition: a kind of sofa footstool, comprise the footstool body, be fixedly connected on the stool pin that is used to support the footstool body under the footstool body, described footstool body comprises the opening casing, is arranged on the opening casing and covers the case lid of opening casing, and casing is connected by hinge versatilely with case lid.Because the sofa footstool has adopted the compound mode of opening casing and case lid, makes the sofa footstool possess the function of depositing object, has improved space availability ratio.This invention is a significant measure in space utilization, but in combined development couch bottom function the comfort aspect of taking one's seat is then got nowhere.
The utility model content
The utility model remedies the deficiencies in the prior art, and a kind of couch that is provided with extensible leg structure is provided, and increases couch bottom function, improves the comfortableness of taking one's seat of couch.
The purpose of this utility model is achieved by following technical proposals: a kind of couch that is provided with extensible leg structure, contain the couch body that comprises the chair pin, the utility model is provided with the extensile leg structure of a cover between the chair pin, described extensile leg structure is by a support independently, be located at the motor on the support, belt pulley, screw mandrel by the belt pulley drive, with screw mandrel fit screw rod nut, the travelling carriage that is connected with the feed screw nut, be provided with the guide rail bracket of the guide rail that cooperates with travelling carriage, be connected in the drawstring on the guide rail bracket, in succession drawstring other end and be provided with the rotating leg pad of reduction torsion spring, be located at the support front end and be provided with the foot pad of reduction torsion spring, and electric cabinet constitutes.
The move distance of described travelling carriage is by two travel switch controls that are located at front-end and back-end on the guide rail bracket.
Motor is located at the rear side middle part of support, by the electric cabinet control that is located at upper lateral part behind the support, if press start button, electric motor starting, being located at the middle screw mandrel of support by the small belt pulley that is located at electric machine main shaft through big belt pulley deceleration back drive rotates, screw mandrel drives the feed screw nut and drives the travelling carriage that is connected with the feed screw nut and travels forward along guide rail, extensile leg pad is released forward, after releasing certain distance, be subjected to the tractive of drawstring, the leg pad begins turning expansion around a rotating shaft, when the leg pad turn to desired location, travelling carriage touches the travel switch that is located at the guide rail bracket front end, and motor stops operating.Also can different outreach be set, thereby make mechanism adapt to the people's of different heights use needs by automatically controlled program.
If press SR, the motor counter-rotating, the travelling carriage withdrawal, drawstring loosens, and the leg pad resets gradually by the power of torsion spring, and during to desired location, travelling carriage touches the travel switch that is located at the guide rail bracket rear end, and motor stops operating, and whole leg structure restPoses.
Below the front end of travelling carriage, be provided with a support roller,, reduce the resistance of motion of travelling carriage simultaneously when travelling carriage can play balanced action when guide rail is put up the cantilever beam state stretching out.
Described foot pad is located at support foremost, but the rotating shaft of foot pad winding on support rotate, in this rotating shaft, also be provided with torsion spring, when seated person is pressed in pin on the foot pad, foot pad flattenings of overturning forward, after the pin of seated person left, foot pad relied on the torsion spring reinstatement.
Also leg pad torsion spring or foot pad torsion spring can be changed to extension spring, an end of extension spring is located on leg pad or the foot pad, and the other end of extension spring is hooked on the support.
The length setting of described drawstring should make travelling carriage can turn to described leg pad pulling the desired location of setting when just releasing outside the support.
Because the weight of travelling carriage is lighter, translational speed is slower, so the fit system of guide rail can adopt the guide rail that is slidingly matched.
Scheme is to be provided with to be no less than two roller on guide rail preferably, makes moving of travelling carriage lighter submissive.
Better scheme is to be provided with to be no less than two rolling bearing on guide rail.
The guide rail of described guide rail bracket can be by the shaped steel manufacturing.
The utility model has following beneficial effect compared with the prior art:
1. be provided with leg pad and foot pad, it is more comfortable to take one's seat, good for health;
2. leg structure is released and is launched and can comfortablely use, and withdrawal is drawn in and then do not occupied;
3. unified with the couch Total tune;
4. automatically controlled setting, motor-driven convenience.
