Description
Technical field
The invention belongs to office appliance and field of furniture, and in particular to be used on to a kind of office chair for office space or house rest etc., a kind of adjustable Chair underframe with reclining apparatus for adjusting force of backrest supporting force.
Background technology
Currently, the office hours of office crowd is generally more than eight hours, office crowd daily on chair spend by about 60% time, due to sitting, along with use unsound seat and incorrect sitting posture, 75% office seating is caused to suffer from cervical spondylopathy in various degree using crowd, protrusion of lumber intervertebral disc, vertebra lateral bending, the diseases such as chest and back pain, with the progress of science and technology, the improvement of people's living standards, healthy living is increasingly becoming emphasis of concern, the office chair for meeting body mechanics of health can effectively reduce the probability for suffering from above-mentioned disease, thus the comfortable office chair of health seems increasingly important to office crowd.Although traditional chair bottom can realize the reclining function of backrest in the market, but the user of consideration different building shape is not different to the demand of back support force, if using constant supporting force, the possible less user of build thinks that backrest supporting force is too big, by not going down, and the larger user of build thinks that backrest supporting force is too small, support force is inadequate.
The content of the invention
For the drawbacks described above and problem of prior art, the technical problems to be solved by the invention are to provide a kind of Chair underframe with reclining apparatus for adjusting force, and its is simple in construction, low manufacture cost.
In order to achieve the above object, the present invention provides following technical scheme：
A kind of Chair underframe with reclining apparatus for adjusting force, including seat shell and reclining apparatus for adjusting force, the reclining apparatus for adjusting force includes steel bar keeper, steel bar, sliding block, screw rod, adjusting knob and backrest connector, the seat shell and backrest connector are connected by steel bar, the steel bar keeper is brought into close contact with sliding block, is spirally connected between the sliding block and screw rod.
In above-mentioned technical proposal, the backrest connector is two, and seat shell both sides set backrest connector mounting hole, and two backrest connectors are separately fixed at seat shell both sides.
In above-mentioned technical proposal, described two backrest connectors are connected by steel bar, and backrest connector is rotated around steel bar.
In above-mentioned technical proposal, the steel bar section is rectangle, and two steel bars are installed side by side.
In above-mentioned technical proposal, the sliding block sets inclined-plane respectively with steel bar keeper, and the bevel angle of sliding block is consistent with the bevel angle of steel bar keeper.
In above-mentioned technical proposal, the external screw thread that the internal thread that the sliding block is set is set with screw rod matches, and when screw rod rotates, can move sliding block.
In above-mentioned technical proposal, the screw rod is fixed using holding screw with adjusting knob.
The present invention realizes the regulation of reclining power using the regulation to end points pretightning force, the backrest of office chair, which can be made, reclining function, and the use demand that backrest during office chair inclination meets different building shape user to the supporting force of user's back, the characteristics of it has simple in construction, low manufacture cost, good effect can be adjusted.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing to be used needed for embodiment or description of the prior art will be briefly described below, apparently, drawings in the following description are only some embodiments of the present invention, for those of ordinary skill in the art, without having to pay creative labor, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 3 is reclining apparatus for adjusting force Local map of the invention.
Wherein:1st, backrest connector；2nd, seat shell；3rd, steel bar；4th, steel bar keeper；5th, adjusting knob；6th, screw rod；7th, sliding block.
Embodiment
Below in conjunction with the accompanying drawing of the present invention, technical scheme is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
According to Fig. 1, Fig. 2, Fig. 3, a kind of Chair underframe with reclining apparatus for adjusting force shown in embodiment, including seat shell and reclining apparatus for adjusting force are used as.
Reclining apparatus for adjusting force includes steel bar keeper, steel bar, sliding block, screw rod, adjusting knob and backrest connector, backrest connector sets the mounting hole of backrest, mutually fixed connector will be leaned against with leaning against, backrest connector is two, seat shell both sides set backrest connector mounting hole, two backrest connectors are separately fixed at seat shell both sides, and two backrest connectors are connected by steel bar, and backrest connector is rotated around steel bar.Steel bar is two, and steel bar section is rectangle, and two steel bars are installed side by side, and steel bar provides the screen resilience resetted after office chair inclination：When user's reclining backrest backward, two steel bars twist deformation, and steel bar resets, then backrest returns to initial position.
Steel bar keeper sets inclined-plane respectively with sliding block, the bevel angle of sliding block is consistent with the bevel angle of steel bar keeper, steel bar keeper is brought into close contact with sliding block, steel bar keeper uses POM materials to process, there is rectangular opening at center, ensure that steel bar is passed through, when steel bar keeper ensure that steel bar two ends are reversed, position maintains the original state, it is ensured that steel bar can reset.
Screw rod is fixed using holding screw with adjusting knob, it is spirally connected between sliding block and screw rod, the external screw thread that the internal thread that sliding block is set is set with screw rod matches, it is spirally connected between sliding block and screw rod, because the bevel angle of sliding block is consistent with the bevel angle of steel bar keeper, therefore steel bar keeper is brought into close contact with sliding block, when screw rod rotates, it can move sliding block, show as the lifting of steel bar keeper.
When sliding block is moved, give steel bar keeper one active force, adjustable pretightning force is now formd on steel bar：I.e., by carrying out rotation regulation to knob, it can make it that the sliding block on the inside of steel bar keeper is in the state of " rising " or " decline ", can be by steel bar keeper jack-up when sliding block rises, pretightning force is applied with to steel bar, become larger with the height of rising, pretightning force is also gradually increased, the supporting force of backrest becomes big, is adapted to the larger user of build；When steel can put down steel bar keeper when sliding block declines, the pretightning force of steel bar is gradually reduced, the supporting force of backrest diminishes, has been adapted to the less user of build.
The above; only embodiment of the invention, but protection scope of the present invention is not limited thereto, any one skilled in the art the invention discloses technical scope in; change or replacement can be readily occurred in, should be all included within the scope of the present invention.Therefore, protection scope of the present invention described should be defined by scope of the claims.
