In the above technical scheme, the backrest connecting pieces are two, the two sides of the seat shell are provided with backrest connecting piece mounting holes, and the two backrest connecting pieces are respectively fixed on the two sides of the seat shell.
In the above technical scheme, the two backrest connectors are connected through the steel bar, and the backrest connectors rotate around the steel bar.
In the technical scheme, the section of the steel bar is rectangular, and two steel bars are installed in parallel.
In the technical scheme, the sliding block and the steel bar positioning piece are respectively provided with inclined planes, and the inclined plane angle of the sliding block is consistent with the inclined plane angle of the steel bar positioning piece.
In the technical scheme, the internal thread arranged on the sliding block is matched with the external thread arranged on the screw rod, and when the screw rod rotates, the sliding block can be moved.
In the technical scheme, the screw is fixed with the adjusting knob by using the set screw.
The invention realizes the adjustment of the tilting force by adjusting the pretightening force of the end points, can enable the backrest of the office chair to have the tilting function, can adjust the supporting force of the backrest to the back of a user in the tilting process of the office chair, meets the use requirements of users with different sizes, and has the characteristics of simple structure, low manufacturing cost and good effect.

Wherein 1, the backrest connecting piece; 2. a seat shell; 3. a steel bar; 4.a steel bar positioning member; 5. an adjustment knob; 6. A screw; 7. a sliding block.
Detailed Description
The following description of the embodiments of the present invention will be made more apparent and fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
According to the embodiment shown in fig. 1,2 and 3, a seat pan with a reclining force adjustment device includes a seat shell and a reclining force adjustment device.
The tilting force adjusting device comprises a steel bar positioning piece, a steel bar, a sliding block, a screw rod, an adjusting knob and backrest connecting pieces, wherein the backrest connecting pieces are provided with mounting holes of the backrest and are used for fixing the backrest connecting pieces and the backrest, the number of the backrest connecting pieces is two, the two sides of the seat shell are provided with mounting holes of the backrest connecting pieces, the two backrest connecting pieces are respectively fixed on the two sides of the seat shell, the two backrest connecting pieces are connected through the steel bar, and the backrest connecting pieces rotate around the steel bar. The steel bars are two, the section of the steel bars is rectangular, the two steel bars are installed in parallel, and the steel bars provide resilience force for resetting the office chair after leaning on: when the user leans back to the back, the two steel bars are deformed in a torsion way, and the steel bars are reset, so that the back returns to the initial position.
The steel bar locating piece and the sliding block are respectively provided with inclined planes, the inclined plane angle of the sliding block is consistent with that of the steel bar locating piece, the steel bar locating piece is tightly attached to the sliding block, POM materials are used for machining the steel bar locating piece, a rectangular hole is formed in the center of the steel bar locating piece, steel bars can be guaranteed to penetrate through the rectangular hole, and when the two ends of the steel bars are twisted, the positions of the steel bar locating piece are kept unchanged, so that the steel bars can be reset.
The screw rod uses holding screw and adjust knob to fix, and the spiro union between slider and the screw rod, the internal thread that the slider set up and the external screw thread phase-match that the screw rod set up, spiro union between slider and the screw rod because the inclined plane angle of slider is unanimous with the inclined plane angle of billet setting element, consequently billet setting element closely laminates with the slider, when the screw rod is rotatory, can make the slider remove, appears as the lift of billet setting element.
When the sliding block moves, an acting force is applied to the steel bar positioning piece, and at the moment, an adjustable pretightening force is formed on the steel bar: that is, the slider at the inner side of the steel bar positioning piece can be in a rising or descending state by rotating and adjusting the knob, when the slider rises, the steel bar positioning piece is jacked up, the pretightening force is applied to the steel bar, the pretightening force is gradually increased along with the gradual increase of the rising height, the bearing force of the backrest is increased, and the backrest is suitable for a user with a larger size; when the sliding block descends, the steel bar locating piece is put down, the pretightening force of the steel bar is gradually reduced, the bearing force of the backrest is reduced, and the steel bar locating piece is suitable for users with smaller body types.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
