A kind of chair frame of dependence flexible adjustment backrest angle, it includes seat leg pipe, adapter sleeve, elastic device, backing tube, bolt；It is characterized in that seat leg pipe is by bolt and adapter sleeve Joint, backing tube passes through bolt and elastic device Joint by bolt and adapter sleeve Joint, adapter sleeve；Seat leg pipe passes through the elastic device Joint provided with helix tube with backing tube, the dependence power born using backing tube, helix tube is promoted to rotate, helix tube rotates the moment of torsion born that the moment of torsion produced counteracts backing tube, thus, the rotational angle of helix tube can be adjusted according to the size of power is leaned on, so as to realize the regulation of backrest angle；Therefore, present invention chair frame that is simple in construction, easy to operate and being suitable as the occasions such as interior, garden is used.
Description
Technical field
The present invention relates to chair technology field, more particularly to a kind of chair frame of dependence flexible adjustment backrest angle.
Background technology
In the chaise longue of adjustable backrest common at present, the regulation of backrest angle is generally realized by three-link mechanism or quadric chain, the backrest for having section chairs realizes angular adjustment by devices such as ratchets, these structures are all that the purpose of regulation positioning is realized using external component, so not only cause cost to increase, and operation difficulty can be increased.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of chair frame of dependence flexible adjustment backrest angle.
The technical solution adopted in the present invention is：A kind of chair frame of dependence flexible adjustment backrest angle, it includes seat leg pipe, adapter sleeve, elastic device, backing tube, bolt；It is characterized in that seat leg pipe is by bolt and adapter sleeve Joint, backing tube passes through bolt and elastic device Joint by bolt and adapter sleeve Joint, adapter sleeve.
Preferably, described seat leg pipe is provided with foot putting tube, turnover arc, seat pipe, internal thread hole；L-shaped is linked to be by arc of transferring between described foot putting tube and seat pipe, internal thread hole is arranged on the port of seat pipe.
Preferably, described adapter sleeve in positioning hole in symmetrical fixing slot and two positioning holes, fixing slot provided between the upper and lower every can pass through bolt with covered joint seat foot tube or backing tube.
Preferably, described elastic device is provided with elastic foot, short stay tube, long stay tube, described elastic foot point row both sides are fixed together by short stay tube and long stay tube.
Further, described elastic foot is provided with seat connecting leg, helix tube, back of the body connecting leg, internal thread hole, and the two ends of described helix tube are provided with the seat connecting leg of integrally connected and carry on the back connecting leg, and the end of seat connecting leg and back of the body connecting leg is provided with internal thread hole.
Further, described helix tube is set more than curl, the set circle of spiral number of turns at least two.
Preferably, backing tube is arranged to U-tube, the port of U-tube is provided with internal thread hole.
The beneficial effects of the invention are as follows：Seat leg pipe passes through the elastic device Joint provided with helix tube with backing tube, the dependence power born using backing tube, helix tube is promoted to rotate, helix tube rotates the moment of torsion born that the moment of torsion produced counteracts backing tube, thus, the rotational angle of helix tube can be adjusted according to the size of power is leaned on, so as to realize the regulation of backrest angle；Therefore, the features such as present apparatus has simple in construction, esy to use, safe and reliable.

Embodiment
Technical scheme is described further below by specific embodiment, and with reference to accompanying drawing.
Embodiment：Reference picture 1, a kind of chair frame of dependence flexible adjustment backrest angle, it includes seat leg pipe 1, adapter sleeve 2, elastic device 3, backing tube 4, bolt 5；It is characterized in that seat leg pipe 1 is by bolt 5 and the Joint of adapter sleeve 2, backing tube 4 passes through bolt 5 and the Joint of elastic device 3 by bolt 5 and the Joint of adapter sleeve 2, adapter sleeve 2.The front end of seat leg pipe 1 lands support, and elastic device 3 lands support, is supported before and after being formed.
Reference picture 2, described seat leg pipe 1 is provided with foot putting tube 11, turnover arc 12, seat pipe 13, internal thread hole 14；L-shaped is linked to be by arc 12 of transferring between described foot putting tube 11 and seat pipe 13, internal thread hole 14 is arranged on the port of seat pipe 13.
Reference picture 3, described adapter sleeve 2 in positioning hole 22 in the symmetrical positioning hole 22 of fixing slot 21 and two, fixing slot 21 provided between the upper and lower every can pass through bolt 5 with covered joint seat foot tube 1 or backing tube 4.
Reference picture 4, described elastic device 3 is provided with elastic foot 31, short stay tube 32, long stay tube 33, and described 31 points of row both sides of elastic foot are fixed together by short stay tube 32 and long stay tube 33.Described elastic foot 31 is provided with seat connecting leg 311, helix tube 312, back of the body connecting leg 313, internal thread hole 14, the end of seat connecting leg 311 and back of the body connecting leg 313 of the two ends of described helix tube 312 provided with integrally connected, seat connecting leg 311 and back of the body connecting leg 313 is provided with internal thread hole 14.Described helix tube 312 is set more than curl, the set circle of spiral number of turns at least two.
Reference picture 5, backing tube 4 is arranged to U-tube, and the port of U-tube is provided with internal thread hole 14.
Reference picture 6, during assembling, seat leg pipe 1 and backing tube 4 are inserted in the fixing slot 21 on connecting seat 2, then by the center alignment of positioning hole 22 on the internal thread hole 14 and connecting seat 2 on seat leg pipe 1, backing tube 4, then bolt 5 is mutually threadedly coupled through positioning hole 22 with internal thread hole 14, after bolt 5 is tightened, seat leg pipe 1, backing tube 4 and the Joint of connecting seat 2.
Reference picture 7, when using, backing tube 4 bears to lean on after power, moment of torsion produced by leaning on power promotes helix tube 312 on elastic device 3 to rotate, and the angle of backing tube 4 rotates, when the moment of torsion that helix tube 312 rotates generation gradually counteracts the moment of torsion born of backing tube, the angle of backing tube 4 realizes balanced support, thus, it is possible to the rotational angle of helix tube 312 be adjusted according to the size of power is leaned on, so as to realize the regulation of the angle of backing tube 4.When cancelling the dependence power on backing tube 4, backing tube 4 can be turned round under the moment of torsion effect of helix tube 312, until the moment of torsion of helix tube 312 disappears, be returned to original state.
Embodiment described above is a kind of preferred version of the present invention, not makees any formal limitation to invention, also has other variants and remodeling on the premise of without departing from the technical scheme described in claim.
