[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and Figure 2The present utility model provides an optical module, including a base 1, and an unlocking member 2 in a strip shape and installed at the optical port of the base 1, one end of the unlocking member 2 is a lock end 20, the lock end 20 is provided with a lock head 22 that can enter or escape from a cage, the other end of the unlocking member 2 is a driving end 21, and a rotating shaft 24 is provided in the middle of the unlocking member 2; when the driving end 21 is lifted, the unlocking member 2 rotates around the rotating shaft 24, and the lock head 22 sinks; the base 1 is also provided with a spring 3 that can lift the lock end 20, and the spring 3 is arranged vertically. In this embodiment, the unlocking member 2 is rotated by the lever principle to realize the unlocking action of the lock head 22 of the lock end 20, and the entire unlocking process does not need to generate displacement in the horizontal direction, and the spring 3 is arranged below the lock end 20 to realize automatic reset, and the spring 3 is arranged vertically, so that the reset process will not generate displacement in the horizontal direction, thereby making the unlocking and reset efficiency of the optical module higher and the optical module structure more compact. Specifically, the unlocking member 2 is in the shape of a long strip as a whole. Along its length direction, one end is the locking end 20, and the other end is the driving end 21. A rotating shaft 24 is provided in the middle part of the unlocking member 2. The rotating shaft 24 and the unlocking member 2 are on the same plane, and its length direction is perpendicular to the length direction of the unlocking member 2. When the unlocking member 2 is lifted from the driving end 21 of the unlocking member 2, the unlocking member 2 rotates around the rotating shaft 24 in the middle. At this time, the locking end 20 sinks, and the lock head 22 can escape from the cage to achieve unlocking. Since the lever principle is used to rotate the unlocking member 2, the overall position of the unlocking member 2 will not move horizontally, and the unlocking stroke is only an up and down swing, and no displacement will occur in the horizontal direction, thereby optimizing the internal structural space of the optical module. In addition, a spring 3 is designed in the base 1. The spring 3 is arranged below the lock end 20. When the lock end 20 sinks, the spring 3 will be compressed. When the driving force of the driving end 21 is removed, the spring 3 will recover under its elastic action, thereby lifting the lock end 20 to the original position. When this original position is designed to be locked, the lock head 22 can be locked into the cage to complete the automatic reset. Since the spring 3 is also arranged vertically, the elastic force is only in the vertical direction, and the reset can be achieved without causing horizontal displacement. Preferably, there are two rotating shafts 24, and the two rotating shafts 24 are respectively arranged on both sides of the unlocking member 2, and the two rotating shafts 24 are coaxially arranged. Preferably, the rotating shaft 24 and the unlocking member 2 are an integrally formed structure.

[0020] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 and Figure 2The base 1 has a U-shaped groove 10 for the shaft 24 to be installed. The U-shaped groove 10 is designed on the base 1 to facilitate the installation of the shaft 24. The base 1 is provided with two U-shaped grooves 10, which are respectively located on both sides of the unlocking member 2, so that the two ends of the shaft 24 can be installed just right. The surface of the shaft 24 is smooth, and the inside of the U-shaped groove 10 is smooth, which will not cause any obstacles to the rotation of the unlocking member 2. Preferably, the shaft 24 is embedded in the U-shaped groove 10 of the base 1, and the upper surface of the base 1 is higher than the upper surface of the shaft 24 embedded in the U-shaped groove 10, which can prevent the shaft 24 from coming out of the U-shaped groove 10.

[0021] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 and Figure 2 The optical module further includes a pull ring 4 for lifting the driving end 21 when rotating. In this embodiment, the pull ring 4 is used to provide driving force to the driving end 21. The pull ring 4 is annular in shape, with a portion inserted into the base 1 and a portion exposed outside the base 1. The portion inserted into the base 1 abuts against the driving end 21. When the pull ring 4 is pulled up, the portion pushes the driving end 21 upward, and under the action of the rotating shaft 24, the locking end 20 sinks to complete unlocking.

[0022] To further optimize the above solution, please refer to Figure 1 and Figure 2 , the base 1 has a receiving groove for the pull ring 4 to be loaded, and the two sides of the receiving groove are connected, and the pull ring 4 located in the receiving groove is below the driving end 21. In this embodiment, a receiving groove is designed on the base 1. After a part of the pull ring 4 is loaded into the receiving groove, the unlocking member 2 is loaded. At this time, the pull ring 4 will be pressed by the unlocking member 2, and the pull ring 4 can abut against the unlocking end 20 of the unlocking member 2. Preferably, the through-port 11 of the receiving groove is inclined. The design of the inclined through-port 11 facilitates the pull ring 4 to enter the receiving groove along the ramp, and can also limit the pull ring 4 to a certain extent. The overall through-port 11 is in two sections, one section is vertically opened on the base 1, and the other section is inclined. When the pull ring 4 enters from the vertically opened section, it will slide into the inclined section, which also plays a certain guiding role.

[0023] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 and Figure 2 A protrusion 23 is provided on the side of the lock end 20 away from the lock head 22, and the protrusion 23 abuts against the spring 3. In this embodiment, the protrusion 23 is designed to be convenient for cooperation with the spring 3. Preferably, the protrusion 23 is inserted into the spring 3. The protrusion 23 is designed to be slightly longer and can be inserted into the spring 3, which can play a certain role in limiting the spring 3 and prevent the spring 3 from swinging left and right.

[0024] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 and Figure 2 The optical module further includes an upper cover for limiting the unlocking member 2 from leaving the base 1, and the upper cover is disposed on the base 1. In this embodiment, the upper cover can form a housing with the base 1 for mounting the internal components of the optical module, and can also limit the unlocking member 2 to prevent the unlocking member 2 from leaving the base 1, so that the unlocking member 2 can only rotate, but not leave the base 1. Preferably, the upper cover is mounted on the base 1 by screws.

[0025] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 and Figure 2 , the base 1 is also equipped with a light engine 5. In this embodiment, the base 1 and the upper cover are enclosed to form a housing in which functional components such as the light engine 5 are installed, which has structures such as a light receiving component, a light emitting component, and a circuit board, which are all existing structures and will not be repeated here.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
