Abstract
The utility model aims to help people who have difficulties in self-standing and walking to stand up and walk safely. The aim of the utility model is fulfilled by providing a ratchet rocker type upper beam lifting device of a door frame type mobility aid. The ratchet rocker type upper beam lifting device of the door frame type mobility aid consists of a ratchet rocker, a speed reduction self-locking mechanism, a long winch, supports and the like. Short shafts at two ends of the long winch are arranged in bearing holes in the left support and the right support of the lifting device; a gear is also fixed on the short shaft at one end and drives an output gear of the speed reduction self-locking mechanism fixed on the support of the lifting device at the same end; a wheel disc is arranged at an input shaft end of the speed reduction self-locking mechanism; the ratchet rocker is inserted into the wheel disc and is a ratchet wrench with a ratchet wheel and a pawl; a rocker of the ratchet rocker is longer, so that the operation is very labor-saving. The long winch is rotated through transmission of the speed reduction self-locking mechanism by shaking the ratchet rocker with a single hand, so that one end of a rope wound on the long winch can move up and down and be suspended and fixed through a safety belt bound on a human body, and a user can stand up or sit down and walk safely.
Description
Affiliated technical field:
The present invention relates to the rocker-type upper cross beam lifting device that a kind of lifting device of walking aid, particularly door frame type walking aid are used.
Background technology:
The lifting device of the door frame type walking aid of seeing now, just rope is walked around after the top rail lintel of door frame type walking aid, its one end is wrapped on the capstan arrangement that is arranged on walking aid column middle part, rotate capstan arrangement and be wound around rope, the other end of rope is moved up and down, mobile rope ties up to user seat belt with it by what be connected to this end of rope, user pull-up or put down, reaches and helps user to stand and the object of safety walking.Although the lifting device of this door frame type walking aid is simple, but the rope promoting due to it is to walk around entablature, be connected on two capstan arrangements that are arranged on two root post middle parts, lifting device is one like this, and inconvenience is decomposed, and capstan arrangement also will take certain use width, make walking aid become very wide, during use, also need both hands to operate, very effort, very inconvenient simultaneously.
Summary of the invention:
The object of the invention is to provide a kind of lifting device of more practical, handy door frame type walking aid, make the door frame type walking aid of this lifting device, can benefit vast standing and the people of walking disorder, improve their quality of life and self-care ability.
The object of the present invention is achieved like this: the rocker-type upper cross beam lifting device that door frame type walking aid is used by ratchet rocking bar, deceleration self-locking mechanism, long capstan winch, bearing, etc. parts form.The minor axis at long capstan winch two ends is contained in the dead eye on two bearings in lifting device left and right, on the minor axis of one end, be also fixed with therein a gear, this gear again with the output gear phase interlock that is fixed on the deceleration self-locking mechanism on the lifting device bearing of same one end, input shaft end at deceleration self-locking mechanism is equipped with a wheel disc, ratchet rocking bar is inserted on this wheel disc, the bar of ratchet rocking bar is longer, operates very laborsaving.One hand shakes ratchet rocking bar, drives the transmission of deceleration self-locking mechanism, and long capstan winch is rotated, and one end of rope wound on it, by being strapped in moving up and down and hanging fixingly of seat belt on human body, makes user can stand or sit down and safe walking upright.
Accompanying drawing explanation:
Concrete structure of the present invention is provided by following embodiment and accompanying drawing, in accompanying drawing: Fig. 1, be the door frame type walking aid that proposes according to the present invention and the schematic diagram of lifting device, in Fig. 1: 1. adjustable stand column, 2. pony sill, 3. horn ring, 4. rope, 5. seat belt, 6. long capstan winch, 7. long capstan winch gear, 8. deceleration self-locking mechanism output gear, 9. deceleration self-locking mechanism, 10. wheel disc, 11. ratchet rocking bars,, 12. lifting device bearings.
The specific embodiment:
Details and the working condition of the concrete device proposing according to the present invention below in conjunction with schematic diagram 1, detailed description.
Be contained in door frame type walking aid top. ratchet rocker-type upper cross beam lifting device, it is by being contained in lifting device bearing 12) on; Long capstan winch (6), rope (4), seat belt (5), deceleration self-locking mechanism (9) and be contained in the outfan of deceleration self-locking mechanism (9) and the deceleration self-locking mechanism output gear (8) on input and wheel disc (10) and be arranged on the parts such as ratchet rocking bar (11) on wheel disc (10) and form.Left and right two lifting device bearings (12) of ratchet rocking bar upper cross beam lifting device are arranged on the left and right adjustable column (1) of doorframe walking aid, together with the parts such as pony sill (2), horn ring (3) and seat belt (5) of ratchet rocker-type upper cross beam lifting device and door frame type walking aid, just form practical a kind of door frame type walking aid.Ratchet rocking bar (11) is arranged on the wheel disc (10) of deceleration self-locking mechanism (9) input, ratchet rocking bar (11) be one with the ratchet spanner of ratchet and pawl, cost is low, the bar that shakes (11) due to ratchet is longer, so the arm of force is long, output torque is just large, push-and-pull is got up very laborsaving, singlehanded push-and-pull operation push-and-pull ratchet rocking bar (11), make to be fixed on the rotation of the wheel disc (10) on deceleration self-locking mechanism (11) input, through deceleration self-locking mechanism output gear (8), make torque output again, by being fixed on the long capstan winch gear (7) on long capstan winch (6), long capstan winch (6) high pulling torque is rotated, because long capstan winch (6) two ends are minor axis bodies, be contained in respectively in the axis hole of lifting device bearing (12) of the right and left, and can in axis hole, rotate, after long capstan winch (6) rotates, dress rope (4) thereon is just wound forward or backwards, make to be connected to rope (4) other end and be strapped in the seat belt (5) on user health, also can be above or under motion, rise and hang fixation, reach and help user to stand up or sit down, and the upright walking object of safety, ratchet rocking bar (11) can adopt the ready-made ratchet spanner with ratchet and pawl, be inserted into the upper use of wheel disc (10), the cost of ratchet rocking bar (11) is low like this, the kind that can select is also a lot, also can adopt an inner ratchet of ratchet rocking bar (11) to be made on the cylindrical of wheel disc 10, ratchet rocking bar only leaves ratchet on (11).
