Description
(1) technical field:
This utility model relates to the novel spring wheelchair, divides by International Patent Classification (IPC) (IPC) to belong to human life need part, health care and amusement branch, medical science or veterinary; The big class of hygiology is transported patient or is made things convenient for patient's equipment; Operating-table or operating chair; The dentistry chair; Funeral apparatus group is specially adapted for weakling's the chair or the technical field of many wheelspans car group.
(2) background technology:
At present, existing and once had about the chair that is specially adapted for the weakling or the technology of many wheelspans car group the demand of novel spring wheelchair was all done very fruitful effort, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Jiang Shijie, Granted publication number is CN2219698Y, China Patent No. (ZL) is: No. 95211580.8 utility model patent title is the utility model patent of " Rocker arm wheel chair ", the technical scheme that is adopted, technical elements in the chair that is specially adapted for the weakling or many wheelspans car group is a routine of great value invention, and it has solved patient effectively can be by the technical problem of the mobile wheelchair of rocking arm oneself.But still have some deficits, it also is difficult to solve damping, and backrest can not be adjusted the technical problem of position.
(3) summary of the invention
The purpose of this utility model is to provide a kind of novel spring wheelchair.To solve damping, backrest can not be adjusted the technical problem of position.
The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: novel spring wheelchair of the present utility model mainly is made of foam-rubber cushion, backboard, base plate, alignment pin, pedal, handle, connecting rod, positioning bar, spring shaft, wheel lower limb, wheel, sleeve, axle, ball, nut.
In shape, structure and combination thereof, the total essential features of novel spring wheelchair of the present utility model and immediate prior art is: the basal surface position of foam-rubber cushion is bonded in the upper surface position of backboard, base plate, the back that the right end position of handle is threaded in backboard on the top, the right end position of base plate is connected the upper end position of pedal with alignment pin, be combined into the combinative structure of common seat shape, function has been to be seated comfortablely, and go-cart is convenient, places the effect of foot lower limb.The ball position of wheel lower limb is inserted and is connected telescopic interior location, and telescopic lower end position is threaded in the medium position of axle, is combined into the bascule of wheel shape, and function has been moving runner and the effect that is connected wheel.In shape, structure and combination thereof, the novel spring wheelchair of the present utility model technical characterictic different with immediate prior art is: the lower surface position of base plate is threaded in the upper end position of spring shaft, the lower end position of spring shaft is socketed in the upper end position of wheel lower limb, be combined into the cascaded structure of rod-shape, function has been the effect of damping.The lower end position of backboard is connected the left position of base plate with connecting rod, and the left position of connecting rod is fixedly connected on the right end position of positioning bar, is combined into the bascule of hinge shape, and function has been to support, the effect of adjustment position of back.The end positions of axle is connected the draw-in groove position of wheel with ball, and two outer end position of axle are threaded in the center of nut, are combined into the combinative structure of nibbling the wheel shape, and function has been to prevent that wheel from slipping out and the effect that is connected two-wheeled.So just reached novel spring wheelchair of the present utility model and solved damping, backrest can not be adjusted the purpose of the technical problem of position.
The beneficial effect of the novel spring wheelchair of utility model is: this utility model is for solving damping, the technical scheme that technical problem adopted that backrest can not be adjusted the position with existing with once had compared three place's advantage and improvement about the chair that is specially adapted for the weakling or the technology of many wheelspans car group:
First, because the lower surface position that has designed base plate in the technical scheme of novel spring wheelchair of the present utility model is threaded in the upper end position of spring shaft, the lower end position of spring shaft is socketed in the upper end position of wheel lower limb, be combined into the cascaded structure of rod-shape, so the technical problem of easier solution damping.
Second, because the lower end position that has designed backboard in the technical scheme of novel spring wheelchair of the present utility model is connected the left position of base plate with connecting rod, the left position of connecting rod is fixedly connected on the right end position of positioning bar, be combined into the bascule of hinge shape, so easier solution is supported, adjust the technical problem of position of back.
The 3rd, because the end positions that has designed axle in the technical scheme of novel spring wheelchair of the present utility model is connected the draw-in groove position of wheel with ball, two outer end position of axle are threaded in the center of nut, be combined into the combinative structure of nibbling the wheel shape, slip out and the technical problem that is connected two-wheeled so easier solution prevents wheel.
