Then, when in use, an unlocking handle (not shown) is arranged in the driving hole 32, an unlocking rod (not shown) is arranged on the unlocking handle, and the unlocking rod passes through the driving holes 32 on the two regulators positioned at the two sides of the backrest (two ends of the linkage column 5 pass through the first connecting plate 1 and the second connecting plate 2, and the driving hole 32 passes through the linkage column 5, so that one unlocking rod can simultaneously pass through the two driving holes 32); and because the driving hole 32 is prismatic, preferably square, also can be triangle-shaped or hexagon etc. so with driving hole 32 shape matched with the unlocking lever only need insert driving hole 32 can, simple and convenient.
When the angle of the backrest needs to be adjusted, the driving handle is rotated, the driving handle drives the two driving holes 32 to rotate, the driving holes 32 drive the linkage column 5 to rotate, and when the linkage column 5 rotates, the protrusion part 10, the reset part 26 and the blocking part 31 are also driven to rotate; in the process of rotation of the protruding part 10, the control plate 11 is driven to rotate, the three driving posts 19 uniformly distributed on the control plate 11 also rotate, at this time, the three driving posts 19 are respectively clamped in the three driven grooves 20, so the driven grooves 20 are also driven to rotate, the driving ring 17 provided with the driven grooves 20 is also driven to rotate, the first driving groove 21 and the second driving groove 22 on the driving ring 17 also rotate simultaneously, and when the control plate 11 rotates, the first pushing body 13 and the first avoiding groove 14 at the edge of the control plate are also driven to rotate;
first, in the first state, since the driven body 23 is located in the first driving groove 21 but the movable body 6 cannot rotate (is limited by the inner wall of the limit groove 4) with the rotation of the driving ring 17, the driven body 23 gradually transits from the first driving groove 21 to the second driving groove 22 (the first driving groove 21 and the second driving groove 22 are in the circular arc transition structure, so that the transition can be gradually passed without being blocked by the stepped structure);
when the driven body 23 reaches the second driving groove 22, since the distance between the second driving groove 22 and the linkage post 5 is smaller than the distance between the first driving groove 21 and the linkage post 5, the driven body 23 acts to move toward the linkage post 5, and then the locking teeth 7 are separated from the positioning teeth 9 in the process, so that the second connection plate 2 and the backrest connected with the second connection plate 2 can be rotated normally.
When the backrest rotates to a proper position, the unlocking handle is released; in the use process of the whole angle adjuster, the reset volute spring 28 is in a compressed state, and after the unlocking handle rotates the linkage column 5, the compression degree of the reset volute spring 28 is larger; then after the unlocking handle is loosened, the reset volute spring 28 has a tendency of reverse rotation, and meanwhile, the middle part of the reset volute spring 28 is clamped on the prismatic reset part 26, and the edge is clamped in the anti-rotation groove 30 through the anti-rotation part 29, so that the reset volute spring 28 can drive the reset part 26 to rotate instead of the relative rotation between the reset part 26 and the reset part; during the rotation of the reset portion 26, the link post 5 drives the control plate 11 and the drive ring 17 to rotate reversely; in the process of the reverse rotation, the arc-shaped first pushing body 13 is transited into the second abdicating groove 16, the arc-shaped second pushing body 15 is transited into the first abdicating groove 14, and as the first pushing body 13 and the second pushing body 15 are both in a convex shape, the control plate 11 can drive the movable body 6 to move towards the direction far away from the linkage column 5 until the last locking tooth 7 is meshed with the positioning tooth 9, so that the purpose of fixing the first connecting plate 1 and the second connecting plate 2 again is realized, and the backrest is also fixed; wherein in the process, the driven body 23 moves from the second driving groove 22 into the first driving groove 21 again, waiting for the next angle adjustment.
In the process of separating the movable body 6 from the positioning ring 8, the first pushing body 13 and the first abdicating groove 14 rotate relatively to the movable body 6 until the inner walls of the first abdicating groove 14 and the second abdicating groove 16 are attached to each other, at this time, the first abdicating groove 14 and the second abdicating groove 16 provide a space so that the movable body 6 can move towards the direction of the linkage column 5, and finally, after the inner walls of the first abdicating groove 14 and the second abdicating groove 16 are attached to each other, the driven body 23 also butts against the end of the second driving groove 22, so that the second driving groove 22 cannot rotate continuously, and the driving ring 17 and the control plate 11 cannot rotate continuously, so that the first driving groove 21 makes the second connecting plate 2 and the backrest not rotate infinitely, but can only rotate by a certain angle, and at this angle, the inner wall of the first driving groove 21 can be well attached to the inner wall of the second driving groove 22, therefore, the movable body 6 is prevented from excessively moving towards the direction of the linkage column 5, and when the control plate 11 rotates reversely, the first pushing body 13 pushes the movable body 6 to move outwards;
similarly, after the movable body 6 is engaged with the positioning ring 8, the inner wall of the first driving groove 21 can prevent the driving ring 17 from rotating excessively, so that the first pushing body 13 can be stably located in the second receding groove 16, the second pushing body 15 can be stably located in the first receding groove 14, and in this state, the return spiral spring 28 can continuously maintain a good elastic force.
Wherein, in the process that the driven body 23 moves towards and away from the linkage post 5, the driven piece 25 moves towards and away from the linkage post 5; wherein when the follower 25 moves in the reverse direction toward the link post 5, the follower 25 moves from the driving body 24 to the outer wall of the driving ring 17, and the driving body 24 does not affect the normal movement of the follower 25; when the movable body 6 moves in a direction away from the interlocking column 5, the driving body 24 can also drive the driven member 25 to move at the same time, so that the driving action on the movable body 6 is performed by the second pushing body 15 and the second receding groove 16 at the end portions thereof, and the driven member 23 and the driven member 25 at the side portions thereof, so that the movement stability of the movable body 6 is further improved.
In the axial direction of the linkage post 5, the blocking part 31 is positioned between the resetting part 26 and the first connecting plate 1, so when the linkage post 5 rotates, the blocking part 31 can prevent the resetting spiral spring 28 and the first connecting plate 1 from rotating relatively, the abrasion to the resetting spiral spring 28 is slowed, and the service life of the resetting spiral spring is prolonged; meanwhile, the section of the reset part 26 is larger than that of the bulge part 10, so that the reset part 26 can also limit the control panel 11, and the relative friction between the control panel 11 and the reset volute spring 28 is well prevented; although the control plate 11 is also rotated, the return spiral spring 28 is deformed and thus moves relative to the control plate 11, but the return spiral spring 28 is separated from the control plate by the return unit 26 to a certain extent, so that abrasion of the return spiral spring 28 is reduced.
The connecting protrusion 34 facilitates connection between the first connecting plate 1 and the second connecting plate 2 and an external structure, such as welding, that is, the first connecting plate 1 is welded to the seat, and the second connecting plate 2 is welded to the backrest, so that the operation convenience of welding is higher because the connecting protrusion 34 protrudes from the outside of the first connecting plate 1 or the second connecting plate 2.
It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
