The specific working principle of the angle adjuster is as follows;
when the chair is installed, firstly, the chair back connecting plate 2 is locked on a backup plate of a chair through bolts, and the chair seat connecting plate 3 is locked on a seat plate of the chair;
when the inclination angle of the seat back plate needs to be adjusted, the hand lever 43 is pulled upwards manually, the hand lever 43 drives the second rotating shaft 46 to rotate counterclockwise, the clamping plate 42 is synchronously driven to rotate counterclockwise, after the clamping plate 42 rotates to a certain angle, the meshing state between the clamping plate 42 and the gear plate 41 is cut, meanwhile, the second rotating shaft 46 drives the sliding arc tube 543 to rotate counterclockwise through the fourth rotating shaft 541 which is coaxially and fixedly connected with the second rotating shaft, the sliding arc tube 543 drives the guiding arc tube 544 to be guided into the arc empty groove 545 of the fixed arc tube 542 in the counterclockwise rotating process and generates an extrusion effect on the spring 546, and because the limiting gear rod 53 and the sliding arc tube are in a fixed connection state, the limiting gear rod 53 is also driven to rotate counterclockwise, the single gear tooth at the end of the limiting gear rod 53 is disengaged from the limiting gear 52 in the rotating process, because the gear plate 41 and the limiting gear 52 which are coaxially connected at this time are both in a disengaged free state, the inclination angle of the seat back plate can be freely adjusted by the action of the human body sitting on the seat leaning against the back.
After the angle is adjusted to be comfortable, the control of the hand pull rod 43 is released, the tension spring 44 generates elastic potential energy to pull back the clamping plate 42, so that the clamping plate 42 and the fluted disc 41 are in a return meshing connection state, the positions of the seat connecting plate and the chair back connecting plate are fixed, and the rotation of the seat backing plate is limited and fixed, but in the conventional angle adjuster, the tension spring 44 returns to drive the fluted disc to return to the meshing state again, and the phenomena of unstable resetting, slipping teeth and even tooth breakage occur between the fluted disc 41 and the clamping plate 42 due to the influence of the return fluctuation of the tension spring 44.
The anti-slip tooth structure 5 disclosed in this embodiment can solve the problem well because the second rotating shaft 46 rotates clockwise to drive the fourth rotating shaft 541 to rotate clockwise synchronously in the process of releasing the control of the hand lever 43 and pulling back the tension spring 44, and under the action of the restoring force of the spring 546, the sliding arc tube 543 returns to the original position along the guide rail 547 quickly, so as to drive the limit tooth lever 53 to return to the original position, the single-wheel tooth at the free end of the limit tooth lever 53 is engaged with the gear teeth on the periphery of the limit gear 52 again in the process of returning back, at this time, the sliding arc tube 543 can be fixed still, the fourth rotating shaft 541 stops rotating, and reacts on the second rotating shaft 46 to fix the gear quickly, so that the angle fixing process is completed, in this embodiment, the anti-slip tooth mechanism is additionally provided to play a role in assisting the returning engagement of the toothed disc 41 and the clamping plate 42, the positioning effect is further ensured, and the stability of the seat in the adjusting process can be improved.
If the second rotating shaft 46 is connected with the fourth rotating shaft 541 through the inserting structure, the anti-slip tooth mechanism 5 can be replaced independently when parts in the anti-slip tooth mechanism 5 are damaged, and the overall service life of the angle adjuster is prolonged.
