Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

Referring to fig. 1 to 8, an optical module according to an embodiment of the present invention includes an unlocking mechanism and a base 10, where the unlocking mechanism includes a sliding portion 301 and a rotating portion 302, and the sliding portion 301 drives the rotating portion 302 to rotate around a rotating shaft 3022 in a sliding manner to unlock.

In one embodiment, the sliding portion 301 has a first engaging surface 3011, the rotating portion 302 has a second engaging surface 3024, and the sliding portion 301 contacts the second engaging surface 3024 of the rotating portion 302 through the first engaging surface 3011 and drives the rotating portion 302 to rotate around the rotating shaft 3022.

As an example of an implementation manner, as shown in the figure, the first mating surface 3011 and the second mating surface 3024 are both curved surfaces, and the bending direction and the bending angle of the two curved surfaces are matched.

Referring to fig. 3 and 5, in the present embodiment, specifically, the rotating portion 302 includes a lock head 3021 and a lock tail 3023, the lock head 3021 has a bar-shaped or block-shaped structure, and the lock head 3021 has a lock hook 3025 at an end thereof. The optical module further includes a cover plate 40, the cover plate 40 is provided with a lock hole 401 and an elastic pressing plate 402, and a lock hook 3025 of the lock head 3021 can protrude out of the cover plate 40 through the lock hole 401 on the cover plate 40. The end of the latch hook 3025 is set to be an inclined surface, so that when the optical module is inserted into the cage, the latch hook 3025 can be pressed downward by the inclined surface and the frame of the cage, and after the optical module is completely inserted into the cage, the latch hook 3025 automatically resets, and the elastic pressing plate 402 applies a vertical downward pressure to the lock tail 3023 to automatically lock the optical module in the cage.

The lock tail 3023 may also be a bar or block structure, a rotating shaft 3022 is disposed on the lock tail 3023, and the rotating part 302 is connected to the base 10 through the rotating shaft 3022. As an example of an implementation manner, for the purpose of stability of connection, two connection seats 102 are provided on the base 10, and a shaft hole 103 adapted to the rotating shaft 3022 is provided on the connection seat 102, and the shaft hole 103 may be opened (not closed) to facilitate the mounting of the rotating shaft 3022 on the connection seat 102. The end of the tail 3023 adjacent to the pivot 3022 is connected to the end of the locking head 3021 remote from the locking hook 3025 (or as understood to be opposite to the locking hook 3025), and preferably the locking head 3021 is integrally formed with the tail 3023, which is easy to manufacture and has high overall strength. The end surface of the lock tail 3023 at the end far away from the rotating shaft 3022 is the second mating surface 3024 (it can also be understood that the end of the lock tail 3023 at the end far away from the rotating shaft 3022 is provided with the second mating surface 3024). Referring to fig. 4, the base 10 is provided with a limiting groove 101, and the rotating portion 302 is connected to the base 10 through a rotating shaft 3022 and can rotate in the limiting groove 101 around the rotating shaft 3022 to achieve locking and unlocking.

Referring to fig. 6 and 8, the sliding portion 301 may also be a bar-shaped or block-shaped structure. As an example of an implementation, one end of the sliding portion 301 may be curled to form the first mating face 3011; as another example of the possible embodiment, a column with a curved surface or an inclined surface may be provided at an end of the sliding portion 301, and the curved surface may be the first engagement surface 3011.

As shown in fig. 6 and 8, the slide portion is attached with a certain directionality, and both ends of the slide portion are curled in the structure shown in fig. 6, so that the direction is easily deviated in the assembling process. Therefore, as an example of a preferable possible embodiment, an orientation block 3012 may be provided at the slide portion, and the installation direction is indicated by the orientation block 3012, thereby avoiding an error in the assembly process.

As another example of an implementation manner, the first mating surface 3011 is a curved surface and the second mating surface 3024 is an inclined surface, or the first mating surface 3011 is an inclined surface and the second mating surface 3024 is a curved surface.

Referring to fig. 7, the unlocking mechanism further includes a pull ring 20 for driving the sliding portion 301 to slide. The sliding of the sliding portion 301 by the pulling ring 20 can be achieved in various ways, for example, the pulling ring 20 slides the sliding portion 301, and as shown in fig. 6, the sliding portion 301 slides in a rotating manner, for example, the sliding portion 301 is hinged to the pulling ring 20. For the sliding part 301 with a strip-shaped or block-shaped structure, one end of the sliding part 301 can be curled around the pull ring 20 and is coated outside the pull ring 20, so that the sliding part 301 is hinged with the pull ring 20. At this time, as a preferred embodiment, the pull ring 20 may include a linear rod 201 and a T-shaped rod 202, two ends of the T-shaped rod 202 are respectively connected to two ends of the linear rod 201, a protrusion 203 is formed at a middle position of the linear rod 201, and the sliding portion 301 is hinged to the protrusion 203, so that the size of the optical module may be reduced, and the base 10 may be prevented from protruding outward corresponding to a position where the sliding portion 301 is connected to the pull ring 20.

Referring to fig. 8a and 8b, the arrows indicate the moving direction, wherein the curved arrow indicates the moving direction of the tab 20, the arrow pointing to the left indicates the moving direction of the sliding portion 301, the arrow pointing to the lower indicates the moving direction of the lock head 3021 of the rotating portion 302, and the arrow pointing to the upper indicates the moving direction of the lock tail 3023 of the rotating portion 302. The base 10 is provided with a sliding groove 104, during unlocking, the pull ring 20 is rotated, the pull ring 20 drives the sliding part 301 to slide in the sliding groove 104 in the rotating process, the first matching surface 3011 of the sliding part 301 is in contact with the second matching surface 3024 of the rotating part 302, because the rotating part 302 cannot slide and can only rotate around the rotating shaft 3022, therefore, the sliding part 301 gives the vertical upward jacking force to the rotating part 302 through the second matching surface 3024 in the sliding process, so that the lock tail 3023 moves vertically upwards, based on the lever principle, the lock 3021 moves vertically downwards, and when the vertical upward jacking force to the lock tail 3023 given by the sliding part 301 is balanced with the vertical downward pressure to the lock tail 3023 given by the elastic press plate 402, unlocking is realized.

The optical module and the unlocking mechanism provided by the embodiment have simple unlocking mode, can realize unlocking only by rotating the pull ring 20 by a small angle, and compared with the prior optical modules which can realize unlocking only by rotating the pull ring by a small angle, the optical module and the unlocking mechanism provided by the embodiment have smaller requirements on unlocking environment and space, and have stronger applicability.
