Abstract

In order to help the people who have difficulties in standing up independently and walking to stand up and walk safely, the invention discloses a ratchet wheel rocker type upper beam lifting device of a doorframe-type walking aid. The ratchet wheel rocker type upper beam lifting device of the doorframe-type walking aid is composed of the components including a ratchet wheel rocker, a slowdown self-lock mechanism, a long windlass, supports and the like. Short shafts at two ends of the long windlass are arranged in bearing holes formed in the supports, including a left support and a right support, of the lifting device. A gear is further fixed on the short shaft at one end of the long windlass, wherein the gear is in transmission with an output gear of the slowdown self-lock mechanism fixed on the support at the same end of the lifting device. A wheel disc is installed on an input shaft of the slowdown self-lock mechanism, wherein the ratchet wheel rocker is installed on the wheel disc in an inserted mode. The ratchet wheel rocker is a ratchet wrench with a ratchet and a pawl. A rod of the ratchet wheel rocker is long, so that the ratchet wheel rocker is easy to operate. The ratchet wheel rocker is rocked by one hand, the long windlass is enabled to rotate through the transmission of the slowdown self-lock mechanism, one end of a rope wound on the long windlass can move vertically and be hung and fixed through a safety belt bound on a human body, so that a user can stand up, sit down and walk safely.

Description

The ratchet rocker-type upper cross beam lifting device of door frame type walking aid

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, after just rope is walked around the top rail lintel of door frame type walking aid, the 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, the user pull-up or put down, reaches and helps user to stand and the purpose of safety walking.Although the lifting device of this door frame type walking aid is simple, but the rope that promotes due to it is to walk around entablature, be connected on two capstan arrangements that are arranged on two root posts middle parts, and capstan arrangement also will take certain use width, make walking aid become very wide, also need both hands to operate simultaneously during use, very effort, very inconvenient.

Summary of the invention:

The objective 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 dead eye on the bearing of two of about lifting device, also be fixed with therein a gear on the minor axis of an end, this gear again with the output gear phase interlock that is fixed on the deceleration self-locking mechanism on same end lifting device bearing, input shaft end at the deceleration self-locking mechanism is equipped with a wheel disc, the ratchet rocking bar is inserted on this wheel disc, the selection button of torque outbound course is arranged on the ratchet rocking bar, and the bar of ratchet rocking bar is longer, operates very laborsaving.One hand shakes the ratchet rocking bar, by driving the transmission of deceleration self-locking mechanism, long capstan winch is rotated, and an end that is wound around the rope on it makes user can stand or sit down and the safety walking by being strapped in moving up and down and hanging fixingly of seat belt on human body.

Description of drawings:

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. the deceleration self-locking mechanism, 10. wheel disc, 11. ratchet rocking bars, 12. ratchet rocking bars turn to selection button, 13. lifting device bearings.

The specific embodiment:

Below in conjunction with schematic diagram 1, describe details and the working condition of the concrete device that proposes according to the present invention in detail.

Be contained in door frame type walking aid top. ratchet rocker-type upper cross beam lifting device, it is by being contained on lifting device bearing [13]; 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 the parts such as ratchet rocking bar [11] that are arranged on wheel disc [10] form.Left and right two lifting device bearings [13] 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, , also can select button [12] by turning on ratchet rocking bar [11], just can select turning to of push-and-pull ratchet rocking bar [11] power transmission, make wheel disc [10] still inhour rotation clockwise, because the bar of ratchet rocking bar [11] 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 the rotation that is fixed on the wheel disc [10] on deceleration self-locking mechanism [11] input, make torque output through deceleration self-locking mechanism output gear [8], by being fixed on the long capstan winch gear [7] on long capstan winch [6], long capstan winch [6] can be rotated by high pulling torque, because long capstan winch [6] two ends are minor axis bodies, be contained in respectively in the axis hole of lifting device bearing [13] of the right and left, and can rotate in axis hole, after long capstan winch [6] rotates, dress rope [4] thereon just is wound forward or backwards, make and be connected to rope [4] other end and be strapped in seat belt [5] on the 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 purpose of safety, ratchet rocking bar [11] can adopt ready-made ratchet spanner, be inserted into the upper use of wheel disc [10], so ratchet rocking bar [11] cost is low, the kind that can select is also a lot.Also can be made in the inner ratchet of ratchet rocking bar [11] on the cylindrical of wheel disc [10], the ratchet rocking bar only has ratchet on [11].
