Contracting is arranged between the stopper section 41 and the anti-falling piece 6, and such first spring 5 always applies far from locking lock pin 4
The elastic force in the direction in hole 11.Wherein, to make the stopper section 41 on lock pin 4 stretch out the wall of the guide 33, and can be along guide
33 move axially, and are additionally provided on the guide 33 when the lock pin 4 is moved along the guide 33 for avoiding described stop
The axial groove 331 (as shown in Figure 4 and Figure 5) of stopper 41.
In present embodiment, the limited block 212 of radially outwardly projecting, the installation set 32 are provided in the installation axle 21
On be provided with swivelling chute 322 circumferentially, the limited block 212 can be rotated along the swivelling chute 322；The installation set
Compression is provided with second spring 7 between 32 and the armrest body 2, and the second spring 7 is so that limited block 212 is resisted against the rotation
On the side wall of the close armrest body 2 of turn trough 322.Armrest body 2 rotate with by curved surface 211 drive lock pin 4 to
When the direction movement of locking hole 11 or armrest body 2 rotates backward so that when the disengaging locking hole 11 of lock pin 4, in installation axle 21
Limited block 212 is rotated along swivelling chute 322.
Further, as shown in Figure 4 and Figure 5, it is additionally provided in the installation set 32 described in being inserted into the installation axle 21
Mounting groove 321 when installation set 32 for avoiding the limited block 212, the swivelling chute 322 is far from the mounting groove 321
Circumferentially, limited block 212 enters from the insertion end of installation set 32 and is moved along mounting groove 321 for one end of the armrest body 2
It, can be by being rotated into swivelling chute 322 when moving to the position being connected to swivelling chute 322.
Preferably, the junction of the swivelling chute 322 and the mounting groove 321 is provided with stopper protrusion 323, the backstop
Protrusion 323 is for preventing the limited block 212 from being returned again to from the swivelling chute 322 to the mounting groove 321.
To ensure the balance connected between installation axle 21 and installation set 32, it is preferable that be provided in the installation axle 21
Symmetrical two limited blocks 212 are provided with the rotation with 21 corresponding matching of the limited block respectively in the installation set 32
Slot 322.
In addition, in present embodiment, it is provided in the connecting component 3 and enters the locking hole 11 in the lock pin 4
When location structure for positioning the lock pin 4, to prevent lock pin 4 to be detached from locking hole 11.The location structure is preferably institute
State limited block 212 against the swivelling chute 322 side wall on the locating slot 324 that is arranged.In Fig. 5, which sets
It sets in one end of the separate mounting groove 321 of swivelling chute 322.Curved surface 211 in installation axle 21 drives lock pin 4 to enter locking hole
When in 11, armrest body 2 turns to limited block 212 and is located in the locating slot 324, and is protected limited block 212 by second spring 7
It holds in locating slot 324, the using face of armrest body 2 is also overturn to (such as Figure 12-14) upward.When needing adjustable handrail, edge
Touching armrest body 2 towards the radial direction of shaft 31, (width of the axial direction along installation set 32 of swivelling chute 322 limits it
Push range), it may make limited block 212 to be detached from position slot 324, so as to relative to 32 rotating handrail main body 2 of installation set.
The specific operation process for carrying out angular adjustment with armrest installation assembly provided by the invention is as follows：
When being adjusted armrest assembly to another using position from a use position, first, towards the direction of shaft 31
Touch armrest body 2 (width of the axial direction along installation set 32 of swivelling chute 322, which can limit, pushes range) so that handrail master
Limited block 212 on body 2 is detached from locating slot 324, then (is about rotated by 90 °, revolves relative to 3 rotary handle main body 2 of connecting component
The range of turn trough 322 along circumferential direction can limit the angle of the rotation of armrest body 2) so that lock pin 4 can be in the first spring 5
Elastic force effect lower be detached from locking hole 11 (state as Figure 9-Figure 11)；Then armrest body 2 is turned to be used
Angle position drives lock pin at this point, relative to 3 rotary handle main body 2 of connecting component by the curved surface 211 on armrest body 2
4 enter in locking holes 11, while the limited block 212 on armrest body 2 is also stuck in locating slot 324, and armrest body 2 at this time
Using face 22 upward (state as shown in Figure 12-Figure 14), it is thus achieved that armrest body 2 angle to be used determine
Position.
Another aspect of the present invention also provides a kind of seat, which includes armrest installation assembly as described above.This
The seat provided is provided, by using armrest installation assembly as described above, can be appointed according to the needs for driving or resting
Meaning adjustment handrail, thus greatly improves the comfort of seating.
The foregoing is merely the better embodiments of the present invention, are not intended to limit the invention, all the present invention's
Within spirit and principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
