Though yet that aforementioned structure has an assembly cost is low, the economic benefit that can meet the ordinary consumer demand, but because of back of the body frame 1 ' is affixed with seat 2 ' arm-rest frame 3 ', can not adjust back of the body frame 1 ' angle, highly, Gu and the not good disappearance of riding comfort, the suitability is caused at its elevation angle and highly fixing after causing back of the body frame 1 ' to make up.
Known again wheelchair is that frame is provided with atmospheric pressure pole or other can be for adjusting back of the body frame angle structure by carrying on the back, only the whole cost of aforementioned structure also is higher than above-mentioned known product, and cause this wheelchair selling at exorbitant prices can not meet the most consumers burden, have the not good disappearance of economic benefit and popularization.
The utility model content
The purpose of this utility model provides a kind of chair back rack combination angle, highly can adjusted on demand, and can have a wheel chair back rack combinative structure of preferable economic benefit.
For achieving the above object, solution of the present utility model is: a kind of chair back rack combinative structure of taking turns, and mainly by wheelchair body frame body, the flexible body of rod, the combination of wheel chair back rack, wherein: this body frame body back side top, below are provided with the articulated section respectively; Flexible body of rod tool outer tube, interior pipe, and the articulated section is set in outer tube articulate by pivot connecting element and articulated section, body frame body top, and interior pipe is extended through in the outer tube, be provided with in the rear end can for and the articulated section of back of the body frame pivot joint, and can adjust expansion link body pattern length; Back of the body frame is provided with the articulated section in the aforementioned flexible body of rod of correspondence, position, articulated section, body frame body below, is articulated with the flexible body of rod, body frame body respectively by pivot connecting element.
Described outer tube is provided with the protruding button of elasticity, and interior pipe is provided with some locating holes.
Outer tube one end of the described flexible body of rod is provided with the less condensation portion of diameter, and interior Guan Yiduan is provided with the bigger enlarged portion of diameter, and this enlarged portion diameter is greater than condensation portion diameter.
Described back of the body frame is by the interspersed combination of the upper and lower body of rod, and the articulated section is set in this time body of rod below and the body frame body articulates, and the aforementioned flexible body of rod is established by the pivot connecting element group in the top, and the protruding button of elasticity is set; The last body of rod engages back cushion, and corresponding aforementioned pivot connecting element position is provided with rectangular slotted eye, and the protruding button of corresponding aforementioned elasticity position is provided with some locating holes.
After adopting such scheme, this utility model is by above combination, can make in the flexible body of rod pipe displacement make the protruding button of elasticity engage with suitable outer tube locating hole adjusting the back of the body frame angle during operation, and the back of the body frame outer tube can be corresponding to skew on the body frame body with enhancement adjustment smoothness when adjusting; Diameter of inner pipe is greater than condensation portion diameter again, can be by the enlarged portion of the condensation portion of interior pipe and outer tube against block when making the layback of back of the body frame be maximum angle; Carrying on the back frame again can engage with the protruding button of elasticity with adjustment highly by suitable locating hole, and can fold with minimizing and store volume.
