[0007] As a preferred embodiment of this utility model, a protrusion is fixedly provided at the bottom of the housing. The surface of the protrusion is set as an arc surface. The arc surface of the protrusion is closely fitted with the inner bottom of the pull ring. The protrusion is used to limit the pull ring.

[0008] As a preferred technical solution of this utility model, a connector is fixedly provided at the bottom of the housing. The connector is L-shaped and elastic. One end of the connector is integrally formed with a plug-in part. A slot is provided on the inner bottom of the pull ring. The plug-in part is movably inserted into the slot. The plug-in part is tapered. The shape of the slot matches the shape of the plug-in part.

[0009] As a preferred embodiment of this utility model, the surface of the connector is integrally formed with a support rod, the support rod is elastic, and the support rod is used to prevent the connector from deforming.

[0010] As a preferred embodiment of this utility model, an anti-slip strip is fixedly provided on the inner bottom of the pull ring, and multiple anti-slip strips are arranged in an array. The anti-slip strips are used to increase the friction between the pull ring and the hand.

[0015] Compared with the prior art, the present invention provides an optical module unlocking mechanism, which has the following beneficial effects:

[0016] 1. This optical module unlocking mechanism, by setting a hook, pulls the pull ring downward, causing the pull ring to drive the connecting shaft to rotate. At the same time, the connecting shaft drives the pressing part to rotate downward, causing the snap-fit ​​component to rotate around the fixed shaft under the elastic reset action of the torsion spring. Simultaneously, the hook on the other side of the connecting shaft will insert into the limiting groove, hooking the snap-fit ​​component. The rotation of the pull ring will also snap it into the bottom of the housing. This achieves the advantage of being able to lock the unlocking structure through the locking component on the pull ring, preventing the unlocking structure from being easily unlocked when subjected to external force, thus making the installation of the optical module more stable. This solves the problem that when the optical module is subjected to external force, the elastic unlocking structure is easily compressed and unlocked.

[0017] 2. This optical module unlocking mechanism, by setting a cover plate, uses a tool to tighten the fixing screw, causing the fixing bolt to move upward along the internal thread of the threaded hole, disengaging the fixing screw from the threaded hole, thereby unlocking the cover plate. Afterwards, the cover plate can be removed from the housing, completing the disassembly. This achieves the advantage of removing the cover plate from the housing, thereby exposing the internal components and other structures of the housing, facilitating the inspection and maintenance of the internal structure of the housing, and solving the problem of inconvenient unlocking mechanisms for maintenance.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-Figure 3This utility model discloses an optical module unlocking mechanism, including a housing 1, a snap-fit ​​component 2 and a pull ring 3 disposed inside the housing 1. The snap-fit ​​component 2 is disposed inside the housing 1 via a fixed shaft 6. The pull ring 3 is sleeved on the surface of the housing 1 via a connecting shaft 4 and is fixedly sleeved on the surface of the connecting shaft 4. The mechanism also includes: a pressing part 5 disposed on one side of the connecting shaft 4, which is used to press the snap-fit ​​component 2 to rotate and unlock the housing 1; a torsion spring 7 for resetting the snap-fit ​​component 2 is sleeved on the surface of the fixed shaft 6, with one end of the torsion spring 7 fixedly connected to the surface of the snap-fit ​​component 2; a hook component 8 disposed on the other side of the connecting shaft 4, which hooks onto the surface of the snap-fit ​​component 2 for limiting its position; and one end of the pull ring 3 is snap-fitted to the bottom of the housing 1.

[0024] Specifically, a limiting groove 9 is provided on the surface of the snap-fit ​​2, and the hook 8 moves through the snap-fit ​​2 through the limiting groove 9. The hook 8 is set in an arc shape and hooks the snap-fit ​​2 to limit its position.

[0025] In this embodiment, by pulling the pull ring 3, the connecting shaft 4 is rotated, causing the connecting shaft 4 to drive the hook 8 to be inserted into the limiting groove 9, hooking the snap-fit ​​2, thereby limiting the snap-fit ​​2 so that the snap-fit ​​2 will not move when the pull ring 3 is not rotated, thus making the snap-fit ​​on the housing 1 more stable.

[0026] Specifically, a protrusion 10 is fixedly provided at the bottom of the housing 1. The surface of the protrusion 10 is set as an arc surface. The arc surface of the protrusion 10 is tightly fitted with the inner bottom of the pull ring 3. The protrusion 10 is used to limit the pull ring 3.

[0027] In this embodiment, the rotation of the pull ring 3 will squeeze the protrusion 10 at the bottom of the housing 1, so that the pull ring 3 and the protrusion 10 fit tightly together, thereby limiting the position of the pull ring 3.

[0028] Specifically, a connector 11 is fixedly provided at the bottom of the housing 1. The connector 11 is L-shaped and elastic. One end of the connector 11 is integrally formed with a plug-in part 13. A slot 12 is provided on the inner bottom of the pull ring 3. The plug-in part 13 is movably inserted into the slot 12. The plug-in part 13 is tapered, and the slot 12 and the plug-in part 13 are adapted to each other.

[0029] In this embodiment, the pull ring 3 rotates downward, causing it to press against the inclined surface of the insertion part 13. The insertion part 13 causes the connector 11 to elastically deform, and then the pull ring 3 rotates until the slot 12 on the surface contacts the insertion part 13. At the same time, the connector 11 elastically resets, causing the insertion part 13 to be inserted into the slot 12, thereby limiting the pull ring 3. There are two implementation methods. The connector 11 is made of plastic or metal spring sheet and has elasticity.

[0030] Specifically, the surface of the connector 11 is integrally formed with a support rod 14, which is elastic and is used to prevent the connector 11 from deforming.

[0031] In this embodiment, when the connector 11 deforms, it will cause the support rod 14 to deform together. The support rod 14 can support the connector 11, making the connector 11 less prone to deformation, thereby making the pull ring 3 more stable.

[0032] Specifically, an anti-slip strip 15 is fixedly provided on the inner bottom of the pull ring 3. Multiple anti-slip strips 15 are arranged in an array. The anti-slip strips 15 are used to increase the friction between the pull ring 3 and the hand.

[0033] In this embodiment, the hand holds the pull ring 3, so that the hand comes into contact with the anti-slip strip 15 on its surface. The anti-slip strip 15 is made of rubber, which can increase the friction between the pull ring 3 and the hand and prevent slippage when pulling the pull ring 3.

[0034] Specifically, a buckle part 16 is fixedly provided at the bottom of the pull ring 3. The buckle part 16 is arc-shaped and is used by the hand to pull it to drive the pull ring 3 to rotate.

[0035] In this embodiment, the hand holds the buckle 16, and then the buckle 16 is pulled, causing the pull ring 3 to rotate around the connecting shaft 4, so that the pull ring 3 is disengaged from the protrusion 10. The buckle 16 makes it easy to pull the pull ring 3 to unlock.

[0036] Specifically, a cover plate 17 is provided on the top of the housing 1 through an opening, and the cover plate 17 is detachably provided on the top of the housing 1.

[0037] In this embodiment, by removing the cover plate 17 from the housing 1, the snap-fit ​​components 2 and other structures inside the housing 1 can be exposed, making it easier to inspect and maintain the internal structure of the housing 1.

[0038] Specifically, the inner wall of the housing 1 is provided with a threaded hole 18, and the surface of the cover plate 17 is provided with a fixing screw 19, which is threaded through the cover plate 17 and connected to the inner wall of the threaded hole 18.

[0039] In this embodiment, the fixing screw 19 is turned by a tool, so that the fixing screw 19 moves upward along the internal thread of the threaded hole 18, so that the fixing screw 19 is disengaged from the threaded hole 18, thereby unlocking the cover plate 17. Then the cover plate 17 is removed from the housing 1 to complete the disassembly.

[0040] Specifically, a through hole 20 is provided on the surface of the cover plate 17, and the fixing screw 19 passes through the through hole 20 through the cover plate 17. The through hole 20 is convex, and the fixing screw 19 is adapted to fit inside the through hole 20.

[0041] In this embodiment, when the cover plate 17 is installed, the fixing screw 19 passes through the through hole 20 through the cover plate 17, and then the fixing screw 19 is threadedly connected to the threaded hole 18. The fixing screw 19 will be completely inserted into the through hole 20, which can hide the fixing screw 19 and prevent the fixing screw 19 from being exposed outside the through hole 20.

[0042] The working principle and usage process of this utility model are as follows: When disassembling the optical module from the switch cage, hold the latch 16 with your hand and pull it to make the pull ring 3 rotate around the connecting shaft 4, so that the pull ring 3 disengages from the protrusion 10. At the same time, the pull ring 3 will drive the connecting shaft 4 to rotate, so that the connecting shaft 4 will drive the pressing part 5 on one side to press one end of the snap-fit ​​2. One end of the snap-fit ​​2 will move upward, and the center of the snap-fit ​​2 will rotate around the fixed shaft 6. At the same time, the other end of the snap-fit ​​2 will move downward. A torsion spring 7 is movably sleeved on the surface of the fixed shaft 6. One end of the torsion spring 7 is fixedly connected to the snap-fit ​​2, and the other end is fixedly connected to the fixed shaft 6. The rotation of the snap-fit ​​2 will cause the torsion spring 7 to deform elastically. At the same time, the insert at the other end of the snap-fit ​​2 will disengage from the slot in the switch cage, thereby unlocking the housing 1. When the connecting shaft 4 rotates, it will drive the hook 8 on the other side to rotate, so that it disengages from the limiting slot 9. Then pull the pull ring 3 to drive the housing 1 to disengage from the switch, thus completing the disassembly.

[0043] During optical module installation, keep the latch 2 in the unlocked state, then insert the housing 1 into the switch cage. Next, pull the pull ring 3 downwards, causing the pull ring 3 to drive the connecting shaft 4 to rotate. At the same time, the connecting shaft 4 drives the pressing part 5 to rotate downwards, causing the latch 2 to rotate around the fixed shaft 6 under the elastic reset action of the torsion spring 7. This causes one end of the latch 2 near the pressing part 5 to move downwards, while the other end moves upwards, allowing the plug at the other end to insert into the slot in the switch cage, thus limiting the housing 1. Simultaneously, the hook 8 on the other side of the connecting shaft 4 will insert into the limiting slot 9, hooking the latch 2 and thus limiting the latch 2. This prevents the latch 2 from moving without rotating the pull ring 3, making the latch 2 more stable when engaging the housing 1. At the same time, the rotation of the pull ring 3 will press the protrusion 10 at the bottom of the housing 1, causing the pull ring 3 to fit tightly against the protrusion 10, thus limiting the pull ring 3.

[0044] In summary, this optical module unlocking mechanism, by setting the hook 8, achieves the advantage of being able to lock the unlocking structure through the locking component on the pull ring 3, preventing the unlocking structure from being easily unlocked when subjected to external force, thus making the installation of the optical module more stable. This solves the problem that when the optical module is subjected to external force, the elastic unlocking structure is easily compressed and unlocked.
