Referring to fig. 1 and fig. 2, an optical module provided in an embodiment of the present invention adopts a self-unlocking manner, has no special size requirement on a connection system, and can improve the applicability of the optical module in matching with the connection system. Specifically, the optical module includes a handle (handle)1, a housing (housing)6, a latch (latch)4, and a spindle (spindle) 5; wherein, the handle 1, the unlocking device 4 and the rotating shaft 5 form an unlocking mechanism. The handle 1 is used for applying external force when unlocking, and self-unlocking of the unlocking device 4 is realized.
As shown in fig. 3, to realize the self-unlocking form, the unlocking device 4 includes a rotation portion 41 having a through hole 44, a stopper portion 42 and a stopper portion 43 located on both sides of the rotation portion 41, a movable groove 46 located between the stopper portion 42 and the stopper portion 43, and a locking portion 45 located at one end of the stopper portion 43.
The self-unlocking mode requires the unlocking device 4 to rotate, in the embodiment, a through hole 44 is arranged on the rotating part 41, the rotating shaft 5 is positioned in the through hole 44, and the rotating part 41 realizes the rotation of the unlocking device 4; the locking portion 45 is used to achieve tongue locking and unlocking with the connection system. Wherein, the diameter of the rotating shaft 5 is smaller than that of the through hole 44, so that the rotating shaft 5 is used as a rotating shaft to realize the rotation of the unlocking device 4.
In this embodiment, the rotating shaft 5 may be a cylinder structure, and the material may be metal, such as a rivet. The locking portion 45 has a hook-shaped structure, and a tip portion of the hook-shaped structure extends in a direction of the rotating portion 41, which is opposite to a direction of the braking portion 42. When the unlocking mechanism is locked with the connecting system, the hook-shaped structure hooks the corresponding part of the connecting system to realize locking and fixing.
The handle 1 can reciprocate in the movable groove 46; when the handle 1 moves, the unlocking device 4 is driven to rotate, and then unlocking and locking are achieved. Therefore, in order to improve the effect of the unlocking by rotating the unlocking device 4, in the present embodiment, a hollow portion 12 is provided on the handle 1, and the hollow portion 12 is located at the end of the handle 1 close to the unlocking device 4.
Braking portion 42 runs through fretwork portion 12, and optionally, braking portion 42 can expose outside fretwork portion 12, or have certain height, avoids braking portion 42's height too short and leads to when handle 1 drives braking portion 42 and removes, and braking portion 42 drops by fretwork portion 12, influences unlocking mechanism's unblock effect, poor stability.
The front end of the handle 1 is positioned in the movable groove 46 and reciprocates in the movable groove 46, namely, the handle 1 is positioned between the stopper portion 43 and the stopper portion 42, and the reciprocation of the handle 1 is limited by the stopper portion 42 and the stopper portion 43. Braking portion 42 is used for driving the unlocking ware 4 to rotate according to the pulling force that handle 1 applyed when the unblock, and spacing portion 43 is used for driving the unlocking ware to the antiport according to the thrust that handle 1 applyed when locking, still can prevent that relative movement from appearing in handle 1 and unlocking ware 4, influences the locking state, is fixed the state of handle 1 when not unblock by spacing portion 43, improves unlocking mechanism's stability.
In order to ensure the stability of the unlocking mechanism, in the embodiment, the bottom surface of the movable groove 46 is a curved surface and protrudes in the direction of the braking portion 41; the vertical distance from the stopper portion 42 to the movable groove 46 is larger than the vertical distance from the stopper portion 43 to the movable groove 46.
The bottom of the movable groove 46 is curved and protrudes toward the stopper 42, so that the bottom of the movable groove 46 is prevented from contacting the handle 1 when the unlocking device 4 rotates, and the handle 1 is prevented from moving upward due to the pressing force applied to the handle 1 by the bottom of the movable groove 46. If the handle 1 is changed in position, the movement path of the handle 1 is affected, and the unlocking effect is further affected. It can be seen that the bottom surface of the movable groove 46 is formed as a curved surface, which can ensure the stability of the unlocking mechanism.
In order to make the unlocking device 4 smooth during rotation and avoid interference with the handle 1, the vertical distance from the stopper 42 to the movable groove 46 needs to be greater than the vertical distance from the stopper 43 to the movable groove 46, i.e., the depth of the movable groove 46 on the stopper 42 side is greater than the depth on the stopper 43 side.
When the unlocking device 4 rotates, the handle 1 reciprocates in the movable groove 46, and the braking portion 42 moves in the hollow portion 12, so that the opening width of the movable groove 46 is required to be larger than the shortest distance between the hollow portion 12 and the front end of the handle 1 in order to ensure that sufficient space is reserved between the limiting portion 43 and the braking portion 42 to realize rotation and avoid interference between the limiting portion 43 and the handle 1. Wherein, the shortest distance between the hollow part 12 and the handle 1 is the distance between the hollow part 12 and the end of the handle 1 close to the unlocking device 4.
As shown in fig. 4(a) and 4(b), when the unlocking mechanism of the optical module provided in this embodiment is unlocked, that is, when the locking portion 45 is locked with the tongue piece of the connection system, the positional relationship between the unlocking device 4 and the handle 1 is an initial state, that is, the front end of the handle 1 is located in the movable groove 46, and the front end of the handle 1 abuts against the limiting portion 43, but does not abut against the braking portion 42. The braking portions 42 of the unlocker 4 are located between the hollow portions 12 and are not in contact with both ends of the hollow portions 12 in the length direction. The limiting part 43 can support the handle 1 to avoid moving towards the limiting part 43, so that the handle 1 is fixed, and the handle 1 is prevented from sliding to influence the locking effect of the unlocking structure. During locking, the handle 1 contacts the stopper 43, and the lock 45 moves away from the housing 6.
As shown in fig. 5(a) and 5(b), when the unlocking mechanism of the optical module provided in this embodiment is unlocked, that is, the front end of the hollow portion 12 on the handle 1 abuts against the braking portion 42, and the front end of the handle 1 does not abut against the limiting portion 43. The specific process of unlocking is as follows: the handle 1 moves to the left, and the vertical surface of the hollow part 12 close to the unlocking device 4, that is, the inner side surface of the handle 1 close to the unlocking device 4 gradually approaches the side wall of the braking part 42. In the process that the handle 1 continuously moves to the left, the braking portion 42 is located at the right end of the hollow portion 12, the inner side surface of the handle 1 close to the unlocking device 4 is tightly attached to the side wall of the braking portion 42, and the right end of the hollow portion 12 applies a force moving to the left to the braking portion 42, so that the braking portion 42 tends to move to the left. Since the rotating part 41 below the braking part 42 can rotate around the rotating shaft 5, the unlocking device 4 further realizes anticlockwise rotation, the locking part 45 is lifted upwards, that is, the locking part 45 rotates towards the housing 6, so that the locking part 45 is separated from the connecting system, and unlocking is realized.
When locking is needed again, the handle 1 moves to the right, the front end face of the handle 1 applies acting force to the limiting part 43, so that the limiting part 43 tends to rotate clockwise, the unlocking device 4 is driven to rotate clockwise, the unlocking device 4 is enabled to recover the initial state, and the locking part 45 is locked with the tongue piece of the connecting system.
In order to ensure the stability of the unlocking mechanism during unlocking and locking, the unlocking mechanism needs to be fixed on the housing 6 of the optical module, and specifically, the handle 1 needs to be mounted on the housing 6. When the unlocking mechanism provided by the embodiment is unlocked, the locking part 45 rotates towards the handle 1 and then retracts into the optical module, so that the unlocking effect is prevented from being influenced by interference of the unlocking mechanism and the connecting system.
As shown in fig. 6, to hide the lock portion 45, a hiding groove 65 is provided on the housing 6; when the handle 1 contacts the stopper 42, the lock 45 moves toward the housing 6 and rotates into the hidden groove 65.
In order that the lock portion 45 can be retracted into the hidden groove 65 when unlocked, the length of the hidden groove 65 needs to be greater than or equal to the length of the part of the unlocking mechanism where the unlocker 4 is exposed. When unlocking, the unlocking device 4 rotates around the rotating shaft 5, so that the locking part 45 of the unlocking device 4 rotates into the hidden groove 65, the locking of the locking part 45 and a tongue piece of the connecting system is released, and the unlocking of the optical module and the connecting system is realized.
As shown in fig. 7, after the unlocking mechanism of the optical module is mounted on the housing 6 of the optical module, when the optical module is not unlocked, the locking portion 45 of the unlocking device 4 is exposed to realize locking; when unlocking, the unlocking device 4 is driven by the handle 1 to rotate, the locking part 45 moves upwards to unlock the tongue piece of the connecting system and retracts into the optical module, namely, the groove 65 is hidden, the phenomenon of interference between the unlocking mechanism and the connecting system is avoided, and the use stability is better.
In order to realize stable installation of the unlocking mechanism, the housing 6 is provided with a first fixing groove 61, and the first fixing groove 61 is used for installing the handle 1. In order to realize installation and ensure the use stability of the unlocking mechanism of the optical module, the shape of the first fixing groove 61 is required to be the same as that of the handle 1, and the height of the side wall 66 of the first fixing groove 61 is required to be equal to the thickness of the handle 1, so that the first fixing groove 61 can fix the unlocking mechanism of the optical module, and the influence on the use effect due to sliding is avoided.
One end side wall of the first fixing groove 61 is symmetrically provided with fixing holes 64, and the rotating shaft 5 penetrates through the through hole 44 and is installed in the fixing holes 64. The fixing hole 64 is located at one end of the first fixing groove 61 close to the hidden groove 65, and the first fixing groove 65 is communicated with the hidden groove 65, so that the unlocking mechanism formed after the unlocking device 4 is installed on the handle 1 is just installed into the first fixing groove 65 and the hidden groove 65 at the same time.
The rotating shaft 5 in the unlocking mechanism penetrates through the unlocking device 4 and then is installed on the fixing hole 64, so that the handle 1 carrying the unlocking device 4 is fixed in the first fixing groove 61, and the stability of the unlocking mechanism is improved.
Because the unlocking device 4 is in a rotating state when unlocking is performed, in order to avoid the influence on the stability of the unlocking mechanism when the unlocking device 4 rotates, the relative position of the unlocking device 4 needs to be limited. Therefore, as shown in fig. 8, the optical module provided in this embodiment further includes an unlocking mechanism: a cover plate (cover plate)2 located above the handle 1; an unlocking device 4 is arranged between the cover plate 2 and the handle 1; the rotating shaft 5 penetrates through the through hole 44 and the mounting groove 21 arranged on the cover plate 2 and is fixed on the cover plate 2, and two ends of the rotating shaft 5 are fixed on the shell 6.
One end of the cover plate 2 is provided with an installation groove 21, the installation groove 21 is opposite to the hollow part 12, namely, the installation groove 21 is arranged on the surface of the cover plate 2, which is attached to the handle 1; the mounting groove 21 is used for mounting the unlocking means 4. Under normal conditions, the communication is realized with mounting groove 21 to fretwork portion 12 to when making the braking portion 42 of unlocking ware 4 pass fretwork portion 12, vertical state can be guaranteed to unlocking ware 4, effect when avoiding influencing the rotation.
Specifically, the rotating part 41 of the unlocking device 4 is located in the mounting groove 21, and the rotating shaft 5 is fixed to the cover plate 2 through a through hole 44 provided in the rotating part 41 and the mounting groove 21. When the unlocking mechanism is installed on the housing 6, the rotating shaft 5 passes through the cover plate 2, the installation groove 21 and the through hole 44 in sequence to be fixed, and two ends of the rotating shaft 5 are located in the fixing holes 64.
During unlocking, the handle 1 moves in the opposite direction of the position of the unlocking device 4, taking the state shown in fig. 8 as an example, the handle 1 moves to the left, the hollow part 12 drives the braking part 42 to move to the left, so that the rotating part 41 of the unlocking device 4 rotates around the rotating shaft 5 in the mounting groove 21, the locking part 45 rotates towards the direction of the handle 1, namely, moves anticlockwise, the locking with the tongue piece in the connecting system is released, and the optical module can be normally pulled out.

The two sides of the handle 1 are symmetrically provided with fixed seats 11; meanwhile, the two ends of the handle 1 are respectively provided with the elastic parts 3, and the elastic parts 3 are arranged at the same side of the fixed seat 11.
The two sides of the other end of the cover plate 2 are respectively provided with a bulge 22; the cover plate 2 is provided with the protrusions 22 at a position opposite to the direction of the handle 1 provided with the fixing seat 11. For example, if the holder 11 is provided at the front end of the handle 1, the protrusion 22 is provided at the rear end of the cover 2.
The handle 1 is positioned between the two protrusions 22 so that the two protrusions 22 grip the handle 1. For stability, the distance between the two protrusions 22 is equal to the width of the handle 1, so that the movement direction does not deviate when the handle 1 and the cover plate 2 move relatively.
In order to clamp the handle 1 by the two protrusions 22 to stabilize the state of the handle 1 during movement and avoid displacement, in the present embodiment, one end face of the protrusion 22 is higher than the surface of the handle 1 on the side exposed from the stopper 42, and the other end face of the protrusion 22 is higher than the surface of the cover plate 2 on the side far from the handle 1.
The protrusion 22 and the cover plate 2 are not installed in alignment, the protrusion 22 needs to be exposed in a direction contacting with the handle 1, and the height of the protrusion 22 exposed out of the handle 1 is greater than the height of the brake part 42 needing to be exposed out of the handle 1 for installation, so that the situation that after the unlocking mechanism is installed on the optical module, other parts of the optical module interfere with the brake part 42 to influence the rotation of the brake part 42, and further influence the unlocking and locking effects is avoided.
The handle 1 is clamped by the two protrusions 22, and the positions of the protrusions 22 are the same as those of the fixed seat 11. One end of each elastic element 3 is fixed on the corresponding fixed seat 11, and the other end is fixed on the corresponding protrusion 22. When a user pulls the handle 1 to enable the handle 1 and the cover plate 2 to move in opposite directions, the protrusion 22 and the fixed seat 11 move in opposite directions, and at the moment, the elastic part 3 is in a compressed state; when the user releases the handle 1, the elastic member 3 is in a stretched state, so that the handle 1 and the cover plate 2 are restored to the original state.
