Abstract
The utility model discloses a retractable couch foot-operated mechanism. A fixed sleeve is fixed on the undersurface of a seat board. A rotary handle is arranged in the fixed sleeve, and can rotate in the fixed sleeve. A rotary piece is fixed in the middle of the rotary handle. A connecting piece is rotatablely connected with the rotary piece. The other end of the connecting piece is rotatablely connected with a foot-operated unit. The end of the foot-operated unit is connected with the seat board through a hinge. The foot-operated unit can be folded and unfolded by turning the rotary handle. Accordingly, the utility model has the characteristics of capability of being folded and unfolded, taking up small space, and being operated simply. The utility model can be widely used for rest of people in life.
Description
Technical field
The utility model relates to a kind of couch step mechanism, particularly retractable couch step mechanism.
Background technology
When people are seated on couch or half recumbency when having a rest, often to want pin is lifted, sensation can be more comfortable.Existing couch does not almost carry the parts of leg rest, and this just needs stool or other objects to bear pin, uses not to be very convenient.Even the couch of band leg rest parts is arranged,, make couch take up room greatly because its leg rest parts can not folding and unfolding.
Summary of the invention
The purpose of this utility model be to provide a kind of can folding and unfolding, easy to operate retractable couch step mechanism.
The technical scheme that its technical problem that solves the utility model adopts is: retractable couch step mechanism, below seat board, be installed with fixed cover, in fixed cover, be provided with turning handle, turning handle can rotate in fixed cover, middle part at turning handle is fixed with rotatable lamella, be rotatably connected to brace on rotatable lamella, the other end of brace is rotatably connected on the step device, and the end of step device is connected through the hinge on seat board.
As improvement of the present utility model, described step device is made up of sleeve pipe and expansion link, and expansion link is placed in the sleeve pipe, is provided with lock screw on sleeve pipe, and sleeve pipe flexibly connects with brace and seat board respectively.
The beneficial effects of the utility model are: rotate turning handle, turning handle drives the rotatable lamella rotation, and what the rotating band of rotatable lamella was dynamically connected moves, thereby drive step device shrinks and opens.In addition, only need to rotate turning handle and just can realize that the step device shrinks and opens, therefore, the utility model be except can being used for leg rest, and can also folding and unfolding, seldom takes up room, and operation also makes things convenient for.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the position of the utility model in couch concerns schematic diagram;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the mounting structure schematic diagram of fixed cover and seat board.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, retractable couch step of the present utility model mechanism is installed with fixed cover 2 below seat board 1, and fixed cover 2 can also can directly be welded on the seat board 1 by being bolted on the seat board 1.Be provided with turning handle 3 in fixed cover 2, turning handle 3 can rotate in fixed cover 2, for freely making things convenient for of rotating, is fixed with bearing 12 in fixed cover 2, and bearing 12 is sleeved on the turning handle 3.Be fixed with rotatable lamella 4 at the middle part of turning handle 3, rotatable lamella 4 can rotate with turning handle 3.Be rotatably connected to brace 5 on rotatable lamella 4, the other end of brace 5 is rotatably connected on the step device 6, and the end of step device 6 is connected through the hinge on seat board 1.Rotate turning handle 3, can drive rotatable lamella 4 and rotate, the rotation of rotatable lamella 4 can drive moving of brace 5, and the mobile drive step device 6 of brace 5 is around seat board 1 rotation, thus the folding and unfolding of realization step device 6.When rotatable lamella 4 with brace 5 in line the time, step device 6 is opened fully, and can self-locking fix.When needs are packed up step device 6, as long as rotate turning handle 3, get final product when making rotatable lamella 4 and brace 5 at angle, at this moment, step device 6 will down rotate under the effect of gravity automatically, fall within seat board 1 below.
As shown in Figure 2, described step device 6 is made up of sleeve pipe 7 and expansion link 8, and expansion link 8 is placed in the sleeve pipe 7, is provided with lock screw 9 on sleeve pipe 7, loosening lock screw 9, and expansion link 8 just can stretch in sleeve pipe 7.Vary with each individual, expansion link 8 can be adjusted to suitable position.
Step for convenience and pin can shake on expansion link 8 gently, are arranged with a pair of pedal stroke 10 at the front end of described expansion link 8, and pedal stroke 10 can rotate around expansion link 8, and two pedal strokes 10 connect by cross bar 11.When needs shake both feet, pedal stroke 10 is climbed over the front end of expansion link 8, pedal stroke 10 just can rotate around expansion link 8; When not needing to shake, pedal stroke 10 is turned back, utilize cross bar 11 to rest on the expansion link 8 and get final product.
Because the utility model can either folding and unfolding, seldom takes up room, and only need rotate the folding and unfolding that turning handle just can be realized the step device, and is simple to operate, can be widely used in people's the recreation.
