A latch mechanism as shown in fig. 1-5, comprising: the main locking assembly 100 comprises a first rotating block 10 and a second rotating block 20 which are in rotating fit, a first locking tooth piece 30 and a first handle 50 which are connected with the second rotating block 20, a second locking tooth piece 40 which is matched with the first locking tooth piece 30, a first return spring 60 which is arranged on the first locking tooth piece 30 and the second locking tooth piece 40, and a first pin shaft 70 which is arranged on the first rotating block 10, the second rotating block 20, the first locking tooth piece 30, the second locking tooth piece 40 and the first return spring 60 in a penetrating way; the first rotating block 10 comprises a first steering table 11 and a first convex part 12 arranged on the first steering table 11, the second rotating block 20 comprises a second steering table 21, a hollow part 22 arranged on the second steering table 21 and matched with the first convex part 12, and a second convex part 23 arranged on the second steering table 21 and matched with the first locking tooth piece 30, the second convex part 23 is arranged on one side, far away from the first steering table, of the second steering table 21, and the second convex part 23 is in clamping fit with the first handle 50; the first locking tooth 30 is provided with a third protrusion 31 that engages with the second protrusion 23. Namely, the first locking tooth 30 and the first rotating block 10 are respectively located at two opposite sides of the second rotating block 20, and since the above elements are integrally assembled on the first pin 70, the engagement locking relationship between the first locking tooth 30 and the second locking tooth 40 can be adjusted by the engagement between the first rotating block 10 and the second rotating block 20 and the engagement between the second rotating block 20 and the first locking tooth 30.
The lock mechanism of the present embodiment is used in cooperation with the steering column 600, and connects the lock mechanism to the steering column 600. The locking mechanism of the technical scheme adopts the return spring as one of the locking elements, so that the process is simple, additional customization is not needed, the cost is low, the reliability is higher, the utilization rate is higher, the structure is compact, and the integration level is higher. Specifically, when in the locking state, the first protrusion 12 is not completely engaged with the hollow portion 22, and the second protrusion 23 is in butt engagement with the third protrusion 31, so that the first return spring 60 is compressed, and the first locking tooth 30 is pressed against and engaged with the second locking tooth 40, thereby completing the locking. When the position of the steering column 600 needs to be adjusted by unlocking, the first handle 50 is rotated, so that the second rotating block 20 connected with the first handle 50 is driven to rotate, the second convex part 23 of the second rotating block 20 is separated from the butt joint with the third convex part 31, and due to the reset tension action of the reset spring, the first convex part 12 is completely inserted into the hollow part 22, the second convex part 23 is located at the position adjacent to the third convex part 31, namely, similar to the insertion or embedding mode, at this time, the reset spring separates the first locking tooth piece 30 from the second locking tooth piece 40, namely, the unlocking is completed, and the position of the steering column 600 can be adjusted. When the locking is required again, the first handle 50 is rotated reversely to return to the locked position. The present embodiment increases the reset tension and reset stroke of the first reset spring 60 by the double insurance cooperation of the first protrusion 12 and the hollow portion 22, and the second protrusion 23 and the third protrusion 31, thereby further ensuring the locking effect and the unlocking effect.

At this time, the overall width of both the first rotating block 10 and the second rotating block 20 reaches the maximum, thereby providing a compressive force to the first return spring 60 to snap-lock the first locking teeth 30 and the second locking teeth 40. When the unlocking is needed, the first handle 50 is rotated to enable the first convex part 12 to be completely inserted into the hollow part 22, and at the moment, the total width of the first rotating block 10 and the second rotating block 20 is minimum, so that the first return spring 60 is reset to give way, the first locking tooth piece 30 and the second locking tooth piece 40 are separated, and the unlocking is completed. Because first slip table 122 has the slope to cooperation when rotating between first slip table 122 and the second platform 20 wall can provide transition guide effect for first convex part 12 completely alternates with fretwork portion 22, avoids the too big locking mechanism vibration that leads to the fact of the impact force when unblock or locking, influences use experience and life.
