5. the specific embodiment

Referring to Fig. 1, Fig. 2, this utility model has the chair that helps the energy of rendering meritorious service, it comprises seat support (1), seat (2) and handrail (3), and it also is provided with in order to support seat (2) and with seat support (1) and constitutes the rotatable chair frame (4) that connects, and in order to promote the electronic push rod (5) that chair frame (4) rotates; Seat support (1) generally has backrest (7), they interfix, the dual-side of chair frame (4) and handrail (3) are fixing, the front of chair frame (4) is rotatable with the hinging manner and the forward position of seat support (1) and connects, be provided with electronic push rod (5) in the inner space of seat support (1), it can promote chair frame (4) and rotate relative to seat support (1); For this utility model band is helped render meritorious service can chair can be fit to the old people of each different heights, can make the height of seat support (1) be arranged to adjustable, handrail (3) also can be made adjustable with the spacing of chair frame (4), as long as this makes interconnective parts with the combination of socket form, set the pin-and-hole (9,9 ') of vertical distribution, after adjusting height or spacing, get final product so that latch is fixing again.

Fig. 3, electronic push rod (5) includes housing (502), motor (501), worm gear (504), worm screw (503), bearing (505), screw mandrel (506), feed screw nut (507), push pipe (508) and limit switch (509,509 '); The bottom of housing (502) has hole (510), the bottom of it and seat support (1) links, accommodate worm gear (504) in the bottom of housing (502), worm screw (503) and the ball bearing that matches with worm-wheel shaft, other being fixed with in this bottom in order to drive the motor (501) that worm screw (503) is rotated, straight tube shape at housing (502) partly accommodates screw mandrel (506) and associated bearing holder (housing, cover) (505) and the plane bearing that links with worm-wheel shaft, in the straight tube shape part of housing (502), also accommodate push pipe (508), one end of this push pipe (508) porose (511), it is connected with the rear end of chair frame (4), the other end of push pipe (508) is nested has the feed screw nut (507) of the female thread that matches with screw mandrel (506), and the straight tube shape part of housing (502) has also been set limit switch (509 respectively at active two extreme positions of push pipe (508), 509 '); The motor switch (8) of electronic push rod (5) is located on the handrail (3), press motor switch (8), motor (501) is rotated, driving worm screw (503) rotates, through worm gear (504) speed change, feasible screw mandrel (506) with the worm-wheel shaft interlock rotates with lower speed, thereby the feed screw nut (507) who is nested in push pipe (5 a 08) end and matches with screw mandrel (506) is gone up at screw mandrel (506) to move, reach by push pipe (508) and promote the purpose that chair frame (4) rotates, push pipe (508) is run into limit switch and is just halted when mobile, press motor switch (8) again, and motor is counter-rotating just, push pipe (508) is done oppositely to move, and stops until meeting another limit switch again.

Referring to Fig. 4, the utlity model has more function in order to make, make seat (2) and chair frame (4) separable, and formation flexibly connects, concrete enforcement is such: going up at seat (2) increases a draw ring (201), and between seat (2) and chair frame (4), increase a rocking bar (202) that all becomes to flexibly connect with both, the length of this rocking bar (202) with and set for the Movable joint point of seat (2) and chair frame (4) and to make when seat (2) when being open, after it just in time pastes and hangs over chair frame (4), if (201) then seat (2) is topped again on chair frame (4) for the pulling draw ring, seat (2) and chair frame (4) just can be according to need and folding like this; In chair frame (4), can be equipped with closet (6), like this when the old man need be with regard to the lavatory, as long as seat (2) is pushed open, can be sitting in chair frame (4) and go up with regard to the lavatory, treating to finish with regard to the lavatory can be by motor switch (8), make chair frame (4) tilt to help to stand, clean down after one's death, chair frame (4) is resetted, again seat (2) is retracted by motor switch (8), and still topped on chair frame (4), still sit down; So no matter closet (6) can be made drawer type, and install in the back of chair or unload the neither rest that influences the old man of closet (6) loading or unloading.
