The specific implementation mode is as follows:

the utility model will now be further described by way of specific examples, with reference to figures 1 to 7:

the utility model provides an automobile seat handrail lock, including seat body 1, and the handrail main part 2 that the inner articulates on seat body 1, be provided with handrail skeleton 3 on handrail main part 2, be located vertical or horizontal rotation is connected with unblock handle 4 on handrail skeleton 3 of handrail main part 2 front, be located on the handrail skeleton 3 of unblock handle 4 dorsal side vertical or horizontal sliding connection have the locking seat 5 that has lockpin 6, be located and be provided with hasp 7 that the outer end can be buckled with the locking end of lockpin 6 on the seat body 1 of handrail main part 2 dorsal side, when handrail main part 2 is in the locking state, the outer end of lockpin 6 penetrates within handrail main part 2 and with hasp 7 buckle, and rotate unblock handle 4 and drive locking seat 5 through coupling assembling and keep away from lockpin 6 and slide, in order to realize the buckle separation of lockpin 6 and hasp 7. In this embodiment, the unlocking handle 4 rotates vertically on the armrest frame 3, and correspondingly, the locking seat 5 can slide vertically on the armrest frame 3.

The unlocking handle 4 drives the locking seat 5 and the lock pin 6 to slide relative to the lock catch 7 by virtue of the connecting component so as to realize the buckling and the separation of the lock pin 6 and the lock catch 7, thereby achieving the locking fixation and the locking release of the armrest main body 2.

Furthermore, the connecting assembly may adopt a common rack and pinion transmission assembly, and in this embodiment, the connecting assembly adopts a specific structure that: the coupling assembling is including the transmission pendulum rod 8 that one end was fixed at the back of unblock handle 4, and the other end of transmission pendulum rod 8 is inconsistent with the terminal surface of locking seat 5, is provided with reset spring 9 between locking seat 5 and the handrail skeleton 3. Namely, the rotation releasing handle pushes the locking seat 5 and the lock pin 6 to slide towards the direction away from the lock catch 7 by rotating the swing rod, and the elastic force of the return spring 9 can enable the locking seat 5 and the lock pin 6 to slide and return towards the direction close to the lock catch 7.

In order to optimize the locking and fixing and unlocking operations of the armrest main body 2, a guide surface 12 is arranged at the edge of the locking end of the lock pin 6, when the armrest main body 2 is in a locking state, the rotation unlocking handle pushes the locking seat 5 and the lock pin 6 to slide towards the direction far away from the locking opening through the rotation swing rod, at the moment, the lock pin 6 is buckled and separated with the lock catch 7 to realize the locking and unlocking of the armrest main body 2, and therefore the outer end of the armrest main body 2 can rotate away from the direction of the seat main body 1 until the armrest main body is laid flat for use; when the armrest body 2 is in the unlocked state, when the outer end of the armrest body 2 is rotated to an extreme value toward the seat body 1, the outer end of the lock catch 7 abuts against the guide surface 12, and the lock catch 7 and the lock seat 5 are pushed to slide away from the lock catch 7 along the guide surface 12 by overcoming the elastic force of the return spring 9, so that the lock catch 7 and the lock catch 6 can be buckled without rotating the unlocking handle 4.

Furthermore, in order to enable the locking seat 5 to be stably and slidably connected to the handrail framework 3, more than one connecting lug 10 is arranged on the handrail framework 3, a guide hole is formed in each connecting lug 10, and a guide rod 11 which is slidably connected in the guide hole is arranged on the locking seat 5. In the present embodiment, two coupling lugs 10 are provided, and two corresponding guide rods 11 are provided.

Meanwhile, in order to enable the return spring 9 to stably drive the locking seat 5 to return, the return spring 9 is sleeved on each guide rod 11, and two ends of the return spring 9 are respectively connected with the connecting lug 10 and the corresponding end surface of the guide seat.

Furthermore, the locking notch may adopt a commercially available barb structure, and in this embodiment, in order to stably mount the latch 7 on the seat body 1, the latch 7 adopts a specific structure that: the lock catch 7 is of a U-shaped structure, two U-shaped ends of the lock catch 7 are fixed on the seat main body 1, and the locking end of the lock pin 6 is inserted in the middle of the U-shaped of the lock catch 7 so as to lock the lock pin 6 and the lock catch 7.

Meanwhile, in order to enable the release handle to stably rotate on the handrail framework 3, a handle through groove 13 is formed in the handrail framework 3, a handle casing 14 is sleeved in the handle through groove 13, the release handle is hinged in an inner hole of the handle casing 14 through a first rotating shaft 15, and a return spring 16 sleeved on the first rotating shaft 15 is arranged between the release handle and the handle casing 14. Meanwhile, after the release handle rotates forward to drive the locking seat 5 to slide away from the lock catch 7, the release handle is driven by the elastic force of the return spring 16 to rotate reversely to reset, and the locking seat 5 slides reversely to reset by the elastic force of the return spring 9.

In addition, because the outer end of hasp 7 need penetrate in handrail main part 2 just can be fixed with lockpin 6 lock, the concrete structure that its hasp 7 penetrated handrail main part 2 does: the back of the handrail main body 2 is provided with a locking bottom shell 17 corresponding to the position of the handrail framework 3, the locking bottom shell 17 is provided with a through hole 18, and the through hole 18 is an access passage for the outer end of the lock pin 6 to penetrate into the handrail main body 2 and to be buckled with the lock catch 7.

Furthermore, in order to avoid the design of the through hole 18 from affecting the overall aesthetic appearance of the handrail main body 2 and placing external sundries from the through hole 18 into the handrail main body 2 so as to obstruct the normal buckling work of the latch 7 and the lock pin 6, a cover plate 19 is arranged at the outer port of the through hole 18, one side edge of the cover plate 19 is hinged in the through hole 18 through a rotating shaft, a reset torsion spring 21 sleeved on the rotating shaft is arranged between the cover plate 19 and the locking bottom shell 17, and when the outer end of the latch 7 penetrates into the through hole 18, the other side edge of the cover plate 19 rotates inwards against the elastic force of the reset torsion spring 21; when the outer end of the latch 7 is located outside the through hole 18, the elastic force of the return torsion spring 21 pushes the other side of the cover plate 19 to rotate outwards until the outer end surface of the cover plate 19 is flush with the outer end surface of the locking bottom shell 17.

The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so: all equivalent changes made according to the shape, structure and principle of the utility model are covered by the protection scope of the utility model.
