Description
Technical field
The present invention relates to armarium, refer in particular to a kind of Wheelchair back tube.
Background technology
The carrying wheelchair occurring in the market, it leans against pipe and can fold, but just considers dwindling on car load packaging volume, the comfort level aspect of user is not considered, above leans against the distance of pipe between shaking hands, and keeps identical size with vehicle frame.The folding pipe that leans against, use in carrying on wheelchair is very general, but single consideration reduces car load packaging volume often, above leans against upper two distances between holding of pipe identical with vehicle frame, force user holding two while holding, often will stretch arm, different design closes human engineering, such operation, can use difficulty to increase, be unfavorable for the marketing of product, meanwhile, also can make user feel very uncomfortable.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and a kind of human engineering that both met is provided, and has dwindled again car load packaging volume, has reduced the Wheelchair back tube of packing carrying difficulty.
The technical scheme that the present invention takes is as follows: a kind of Wheelchair back tube, comprise the first pipe portion, the second pipe portion, tee pipe portion, the 4th pipe portion and the 5th pipe portion, and wherein, above-mentioned the first pipe portion is straight tube body, and its one end stretches out, and the other end is connected with the second pipe portion; Above-mentioned the second pipe portion is arc body, and one end of the second pipe portion is connected in the first pipe portion, and the other end is to downward-extension; Above-mentioned tee pipe portion is straight tube body, and the upper end of the 3rd body is connected on the second body, and lower end connects the 4th pipe portion, and the 4th pipe portion 4 is arc body, and the lower end of the 4th pipe portion is connected with the 5th pipe portion; Above-mentioned the 5th pipe portion is straight tube body.
Preferably, the 5th described pipe portion is provided with through hole, and the diameter of through hole is b2, and through hole distance of center circle is c from the distance of the 5th pipe portion bottom; Tee pipe portion is provided with Unilateral-hole, and the diameter of Unilateral-hole is b1, and the distance of center circle of Unilateral-hole is d from the distance of the 5th body bottom.
Preferably, the diameter of each described pipe portion is a, and the distance of five pipe portion bottoms, the first pipe portion upper end to the is b, and the length of the 5th pipe portion is e; The 5th pipe portion and the first pipe portion are f in the hypotenuse distance of fore-and-aft direction, and vertical dimension is g.
Preferably, the distance of outer face to the five pipe portions of the first described pipe portion is h.
Preferably, the angle between described tee pipe portion and the 5th pipe portion is a1; The radian of the second pipe portion is R1; Angle between the first pipe portion and the 5th pipe portion is R2.
Preferably, the size of described a, b, c, d, e, f, g is followed successively by 22.2*1.2mm, 230mm, 16mm, 144mm, 137.8mm, 105.1mm, 60mm.
Preferably, the size of described b1, b2 is followed successively by 4.2mm, 12mm; The size of a1 is 24 degree; The size of R1, R2 is followed successively by 38 degree, 90 degree.
Beneficial effect of the present invention is:
On wheelchair of the present invention, lean against pipe, when considering to dwindle car load packaging volume, also considered user comfort level, the distance leaning against on two between shaking hands on pipe is become to large, increased the comfort level of user.From manufacturing, bend out and both meet car load designing requirement, meet again the handrail tube of the viewpoint of the present invention's proposition, by practice, confirm, use bend pipe size and bend pipe angle in the design, be the most rational.
