Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0031] Example 1

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 6 The embodiment of the present invention provides an anti-loosening QSFP optical module, including a box body 1, a sealing cover 2, a handle 3, a plug 4, a tail plug 5 and a circuit board 6, wherein the sealing cover 2 is detachably arranged on the box body 1, the circuit board 6 is arranged in the box body 1, the plug 4 and the tail plug 5 are respectively arranged at two ends of the circuit board 6, the handle 3 is movably arranged on the box body 1, the QSFP optical module also includes an anti-loosening component for increasing the connection tightness between the box body 1 and the switch, the anti-loosening component is arranged on the box body 1 and connected to the handle 3, and the anti-loosening component includes a locking module, a driving module and a resistance unit;

[0033] The locking module and the driving module are both arranged in the box body 1, the resistance unit is arranged on the surface of the box body 1 and is connected with the locking module through the driving module. When the box body 1 is inserted into the switch, the resistance unit is controlled to work, and the resistance unit controls the driving module to work to drive the locking module to work and fix the box body 1 in the switch. The driving module is connected to the pull handle 3, and when the pull handle 3 moves relative to the box body 1, the driving module is controlled to work to drive the locking module to reset.

[0034] In a specific case of this embodiment, a limiting block 10 is provided on the sealing cover 2 , and the limiting block 10 is located at one side of the circuit board 6 and performs limiting processing on the circuit board 6 .

[0035] In another specific case of this embodiment, the locking module includes a guide seat 12, a positioning dial 13, a group of push arms 15 and a group of locking members. The guide seat 12 is arranged in the box body 1, and a group of locking members are symmetrically and movably arranged on the guide seat 12 and elastically connected therebetween. The positioning dial 13 is movably arranged in the box body 1 and is movably connected to each of the locking members through the push arms 15. The positioning dial 13 is connected to the driving module, and the box body 1 is provided with an anti-slip window 7 for the locking members to extend from the box body 1.

[0036] It should be noted that each group of locking parts includes an anti-slip rubber block 11, a piston rod 19, a hollow tube 18, a spring 20 and a moving block 17. The hollow tube 18 is movably set on the guide seat 12 through the moving block 17, and adjacent moving blocks 17 are elastically connected. The piston rod 19 is movably set on the hollow tube 18 and the two are connected by the spring 20. The anti-slip rubber block 11 is set at the end of the piston rod 19 away from the hollow tube 18 and is adapted to the anti-slip window 7. The hollow tube 18 is movably connected through the push arm 15 and the positioning dial 13.

[0037] It should be noted that the present embodiment is not limited to the above-mentioned spring 20 to connect the piston rod 19 and the hollow tube 18, and a spring sheet or elastic steel plate structure may also be used instead, which are not listed here one by one.

[0038] In actual application, the end of the box 1 with the plug 4 is inserted into the socket of the switch, and the information transmission is realized by inserting the optical fiber into the tail plug 5. In the process of inserting the box 1 into the switch, the driving module can be driven to work under the interference between the interference unit and the switch, so that the adjustment turntable 13 moves in the box 1. Under the action of the push arm 15, the hollow tube 18 can be driven to move toward the outside of the box 1 along the guide seat 12, and the anti-slip rubber block 11 passes through the anti-slip window 7 and fits tightly with the inner wall of the socket of the switch. The piston rod 19 is displaced in the hollow tube 18 to deform the spring 20, so that there is a large friction resistance between the anti-slip rubber block 11 and the switch to prevent the optical module from detaching from the switch. When the optical module needs to be pulled out of the switch, the handle 3 is pulled. At this time, the handle 3 moves relative to the box 1 and drives the driving module to work. The driving module can control the anti-slip rubber block 11 to reset, thereby completing the removal of the optical module.

[0039] Example 2

[0040] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 8 The adjustment turntable 13 is elliptical in shape, and is formed with an adjustment groove 16 that matches its shape. Two sliders 14 are symmetrically and movably arranged in the adjustment groove 16. The sliders 14 are movably connected through push arms 15 and hollow tubes 18. The adjustment turntable 13 is connected to the pull handle 3 through a driving module. When the pull handle 3 moves, the adjustment turntable is controlled to rotate through the driving module to achieve the resetting of the locking member.

[0041] In this exemplary embodiment, the resistance unit includes a resistance plate 8, a connecting rod 34, a collar 22, a push rod 23 and a top window 35, wherein the top window 35 is arranged on the box body 1, one end of the resistance plate 8 is hinged in the top window 35 and is adapted to the shape of the top window 35, a torsion spring is arranged at the hinge of the resistance plate 8, the connecting rod 34 is arranged on the resistance plate 8, the collar 22 is connected to the adjustment dial 13 through the driving module, and the connecting rod 34 is movably connected to the collar 22 through the push rod 23.

[0042] In the process of inserting the optical module into the switch, the switch socket can contact the contact plate 8, so that the contact plate 8 rotates along its hinge until the contact plate 8 is completely rotated into the top window 35. In this process, the ring 22 can be driven to move in the box body 1 through the cooperation between the connecting rod 34 and the push rod 23, thereby pushing the adjustment dial 13 to move synchronously. Under the action of the push arm 15, the anti-slip rubber block 11 extends from the anti-slip window 7 and contacts the inner wall of the switch socket, thereby achieving the optical module. The module is anti-loosening processed, and when the optical module needs to be pulled out of the switch at a later stage, by pulling the handle 3, the handle 3 moves relative to the box body 1 and drives the driving module to work. When the driving module works, it can control the rotation of the adjustment dial 13, and the rotation angle is 90°. Since the adjustment groove 16 on the adjustment dial 13 is elliptical, the center position of the slider 14 and the adjustment dial 13 is reduced. At this time, the anti-loosening rubber block 11 is indirectly driven away from the switch, thereby realizing the resetting of the anti-loosening rubber block 11.

[0043] Example 3

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 as well as Figure 8 The driving module includes a side panel 24, a transmission structure, a telescopic shaft and a side window 9. The number of the side windows 9 is a group and they are symmetrically formed on the box body 1. Each side window 9 is formed with a side panel 24. The side panels 24 are connected to each other, the side panels 24 are elastically connected to the box body 1, the side panels 24 are connected to the handle 3, the telescopic shaft is arranged in the box body 1 and one end is connected to the adjustment turntable 13, and the other end is connected to the side panel 24 through the transmission structure. The ring 22 is sleeved on the telescopic shaft, and the telescopic shaft is controlled to rotate through the transmission structure when the side panel 24 moves.

[0045] As an example in this embodiment, the telescopic shaft includes a connecting block 21, a driving shaft 30 and a clamping shaft 32. The driving shaft 30 is arranged in the box body 1 and is connected to the adjustment turntable 13 through the connecting block 21. A clamping groove 31 is formed in the driving shaft 30. The clamping shaft 32 is movably arranged in the clamping groove 31 and is connected to the transmission structure at one end away from the driving shaft 30.

[0046] When the optical module is inserted into the switch, the contact plate 8 rotates along its hinge and enters the top window 35, thereby driving the drive shaft 30 and the ring 22 to move relative to the card shaft 32 under the action of the push rod 23, thereby adjusting the position of the locking member, and when the optical module needs to be pulled out, the pull handle 3 drives the side plate 24 to move in the side window 9, so that the transmission structure works, and the transmission structure drives the card shaft 32 to rotate. Under the cooperation between the card shaft 32 and the card slot 31, the card shaft 32 and the drive shaft 30 can be driven to rotate, and then the adjustment dial 13 is driven to rotate, thereby indirectly resetting the locking member.

[0047] Example 4

[0048] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 as well as Figure 8 The transmission structure includes a driven wheel 29, a group of driving wheels 26 and a transfer drive unit. The driven wheel 29 is movably arranged in the box body 1 and connected to the card shaft 32. A group of driving wheels 26 are symmetrically movably arranged in the box body 1 through a rotating shaft 33. The driving wheel 26 and the driven wheel 29 are meshed with each other. Both the driving wheel 26 and the driven wheel 29 are bevel gears 25. The transfer drive unit is arranged between the side plate 24 and the rotating shaft 33. When the side plate 24 moves, the rotating shaft 33 is controlled to rotate by the transfer drive unit.

[0049] As an example in this embodiment, the relay drive unit includes a gear 25, a rack 27 and a connecting plate 28. The gear 25 is coaxially connected to the driving wheel 26 through a rotating shaft 33. The rack 27 is movably arranged in the box body 1 and is connected to the side plate 24 through the connecting plate 28. The rack 27 and the gear 25 are meshed.

[0050] Of course, this embodiment is not limited to the cooperation between the above-mentioned rack 27 and gear 25 to control the rotation of the driving wheel 26 and the driven wheel 29, and can also be replaced by direct drive of a stepper motor or a servo motor. They are not listed here one by one, as long as the driving of the rotating shaft 33 can be achieved.

[0051] When the entire optical module needs to be pulled out of the switch, by pulling the handle 3, the side panel 24 can be driven to move relative to the side window 9, and the rack 27 is driven to move at this time. Under the meshing action between the gear 25 and the rack 27, the gear 25, the shaft 33 and the driving wheel 26 can be driven to rotate, thereby driving the driven wheel 29 and the adjustment dial 13 to rotate. The rotation of the adjustment dial 13 can change the position of the slider 14 and the locking piece, thereby indirectly resetting the locking piece and disengaging the locking work of the switch, and completing the smooth removal of the optical module.

[0052] Working principle of the present invention:

[0053] Insert one end of the box 1 with the plug 4 into the socket of the switch, and insert the optical fiber into the tail plug 5 to realize information transmission. In the process of inserting the optical module into the switch, the socket of the switch can contact with the contact plate 8, so that the contact plate 8 rotates along its hinge until the contact plate 8 is completely rotated into the top window 35. In this process, through the cooperation between the connecting rod 34 and the push rod 23, the ring 22 can be driven to move in the box 1, thereby pushing the adjustment turntable 13 to move synchronously. Under the action of the push arm 15, the hollow tube 18 can be driven to move toward the outside of the box 1 along the guide seat 12, and the anti-slip rubber block 11 passes through the anti-slip window 7 and fits tightly with the inner wall of the switch socket. The piston rod 19 is displaced in the hollow tube 18 to cause the spring 20 to deform. , so that there is a large friction resistance between the anti-stripping rubber block 11 and the switch to prevent the optical module from detaching from the switch. When the entire optical module needs to be pulled out of the switch, by pulling the handle 3, the side panel 24 can be driven to move relative to the side window 9, and the rack 27 is driven to move at this time. Under the meshing action between the gear 25 and the rack 27, the gear 25, the shaft 33 and the driving wheel 26 can be driven to rotate, thereby driving the driven wheel 29 and the adjustment dial 13 to rotate, and the rotation angle is 90°. Since the adjustment groove 16 on the adjustment dial 13 is elliptical, the center position of the slider 14 and the adjustment dial 13 is reduced. At this time, the anti-stripping rubber block 11 is indirectly driven away from the switch, the anti-stripping rubber block 11 is reset, and the optical module is smoothly pulled out.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0055] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
