Description

Technical Field

[0001] This utility model relates to the field of fiber optic switch technology, and more specifically, to a heat dissipation structure for a fiber optic switch. Background Technology

[0002] In modern communication equipment, fiber optic switches are key devices that need to operate stably for a long time. Their heat dissipation performance directly affects the reliability and service life of the equipment. Since there is a lot of dust in the equipment's operating environment, it is necessary to install filter devices in the heat dissipation channels to prevent dust from entering. At the same time, these filter components are required to be easy to clean and replace in order to ensure the heat dissipation effect of the equipment.

[0003] However, the heat dissipation structures commonly found on the market have significant shortcomings. Most traditional filter components are fixed in place and require fasteners such as screws to secure them. The disassembly and assembly process is cumbersome and time-consuming. At the same time, due to the unreasonable structural design, parts are easily damaged or lost during frequent maintenance, increasing maintenance costs. In addition, the connection between the filter components and the chassis is not tight enough, which can easily lead to air leakage and vibration, affecting the overall heat dissipation effect and the operational stability of the equipment. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for a fiber optic switch, comprising a switch body, a filter plate on the outer side of the switch body, and a quick-installation mechanism on the filter plate. The quick-installation mechanism includes a plug, a fixing sleeve, a slanted groove, a slider, a transmission block, a locking plate, a locking slot, and a linkage mechanism. The plug is fixed to the outer wall of the switch body and plugged into the filter plate. The fixing sleeve is plugged into the top of the plug. Multiple sets of slanted grooves are distributed on the inner wall of the fixing sleeve. The slider slides within the multiple sets of slanted grooves.

[0009] The present invention is further configured such that a positioning block is provided at the bottom end of the insertion rod, and the positioning block is inserted into the filter plate. The design of the positioning block can ensure the accuracy of the filter plate installation position.

[0010] The present invention is further provided that the fixing sleeve is provided with a plug sleeve, the plug sleeve being adapted to the diameter of the plug rod, and the installation stability can be improved through the precise fit between the plug sleeve and the plug rod.

[0029] Please see Figures 1-5 A heat dissipation structure for a fiber optic switch includes a switch body 1, a filter plate 2 on the outer side of the switch body 1, and a quick-installation mechanism on the filter plate 2. The quick-installation mechanism includes a plug 3, a fixing sleeve 4, a slanted groove 5, a slider 6, a transmission block 7, a locking plate 8, a locking slot 9, and a linkage mechanism. The plug 3 is fixed to the outer wall of the switch body 1 and plugs into the filter plate 2. The fixing sleeve 4 is plugged into the top of the plug 3. Multiple sets of slanted grooves 5 are distributed on the inner wall of the fixing sleeve 4. The slider 6 slides in multiple sets of slanted grooves 5. The transmission block 7 is fixed inside multiple sets of sliders 6. Multiple sets of locking plates 8 are respectively installed inside multiple sets of transmission blocks 7. The locking slot 9 is provided with... Multiple sets of linkage mechanisms are distributed on the outer wall of the insertion rod 3. The linkage mechanism includes a sliding groove 10, a push sleeve 11, a transmission ring 12, a limiting ring 13, a screw 14, a rotating sleeve 15, a toothed ring 16, and a gear 17. Multiple sets of sliding grooves 10 are distributed on the outer wall of the fixed sleeve 4. The push sleeve 11 slides within the multiple sets of sliding grooves 10. The transmission ring 12 is fixed to the outside of the push sleeve 11. The limiting ring 13 is fixed to the outer wall of the fixed sleeve 4. Multiple sets of screws 14 are provided to rotatably connect the fixed sleeve 4 and the limiting ring 13. The rotating sleeve 15 rotates on the outer wall of the fixed sleeve 4. The toothed ring 16 is fixed to the bottom end of the rotating sleeve 15. The gear 17 is installed on the top of the multiple sets of screws 14 and meshes with the toothed ring 16.

[0030] A sealing gasket 18 is provided between the filter plate 2 and the body of the exchanger 1. The sealing gasket 18 fills the gap through elastic deformation to achieve airtightness.

[0031] The bottom end of the insertion rod 3 is provided with a positioning block 19, which is inserted into the filter plate 2. The positioning block 19 achieves accurate positioning by cooperating with the filter plate 2 to prevent installation deviation.

[0032] The fixed sleeve 4 is provided with a plug sleeve 20, which is adapted to the diameter of the plug rod 3. The plug sleeve 20 increases the contact area and improves the connection strength by tightly fitting with the plug rod 3.

[0033] The outer wall of the insertion rod 3 is provided with guide strips 21, and there are multiple sets of guide strips 21. The inner wall of the insertion sleeve 20 is provided with guide grooves 22, and there are multiple sets of guide grooves 22 that are slidably connected to multiple sets of guide strips 21. The guide strips 21 can restrict rotation by sliding in the guide grooves 22, thus ensuring the installation direction.

[0034] Multiple sets of inclined grooves 5 are inclinedly arranged inside the fixed sleeve 4, and multiple sets of sliders 6 slide inclinedly in the multiple sets of inclined grooves 5 respectively. When the sliders 6 slide in the inclined grooves 5, they generate radial force to achieve self-locking function.

[0035] The top surface of the push sleeve 11 is set in an arc shape and abuts against the bottom surface of multiple sets of transmission blocks 7. The arc-shaped push sleeve 11 can reduce the contact resistance with the transmission blocks 7, making the movement smoother.

[0036] The outer side of the rotating sleeve 15 is provided with anti-slip strips 23. Multiple sets of anti-slip strips 23 are distributed on the outer wall of the rotating sleeve 15. The anti-slip strips 23 increase the surface roughness and improve the friction when gripping.

[0037] In this embodiment, when the filter plate 2 needs to be disassembled, the counterclockwise rotating sleeve 15 drives the gear ring 16 to rotate and mesh with multiple sets of gears 17 respectively, driving the multiple sets of gears 17 and screws 14 to rotate. Through the multiple sets of screws 14 and the transmission ring 12, the transmission ring 12 drives the push ring to release the contact with the multiple sets of transmission blocks 7. The multiple sets of transmission blocks 7 slide outward along the inclined groove 5 through the slider 6 and drive the clamping plate 8 to disengage from the clamping groove 9, releasing the clamping of the insertion rod 3. Then, the fixing sleeve 4 is disengaged from the insertion rod 3, releasing the clamping of the filter plate 2, and the filter plate 2 is separated from the positioning block 19 and the insertion rod 3, completing the disassembly of the filter plate 2.

[0038] More specifically, when the filter plate 2 needs to be installed, the filter plate 2 is inserted into the positioning block 19 and pressed tightly with the sealing gasket 18. Then, the fixing sleeve 4 is inserted into the insertion rod 3, and the guide strip 21 is positioned and inserted through multiple sets of guide grooves 22. Then, the rotating sleeve 15 is rotated clockwise and driven by the meshing of the gear ring 16 and multiple sets of gears 17 to drive multiple sets of screws 14 to rotate. The rotation of the multiple sets of screws 14 is threaded with the transmission ring 12, which drives the push sleeve 11 to slide along the slide groove 10 and pushes multiple sets of transmission blocks 7. The multiple sets of transmission blocks 7 slide upward along the inclined groove 5 through the slider 6 and push the clamping plate 8 to engage in the clamping groove 9, thereby clamping the insertion rod 3 and fastening the filter plate 2.

[0039] In summary, during the use or operation of the overall equipment: when it is necessary to disassemble the filter plate 2, the counterclockwise rotation of the rotating sleeve 15 drives the gear ring 16 to rotate and mesh with multiple sets of gears 17, which in turn drives the multiple sets of gears 17 and screws 14 to rotate. Through the threaded engagement of the multiple sets of screws 14 and transmission rings 12, the transmission rings 12 drive the push ring to release the contact with the multiple sets of transmission blocks 7. The multiple sets of transmission blocks 7 slide outward along the inclined groove 5 through the slider 6 and drive the clamping plate 8 to disengage from the clamping groove 9, releasing the clamping of the insertion rod 3. Then, the fixing sleeve 4 disengages from the insertion rod 3, releasing the clamping of the filter plate 2, and disengaging the filter plate 2 from the positioning block 19 and the insertion rod 3, thus completing the disassembly of the filter plate 2.

[0040] When the filter plate 2 needs to be installed, insert the filter plate 2 into the positioning block 19 and press it with the sealing gasket 18. Then, insert the fixing sleeve 4 into the insertion rod 3 and position it through the multiple sets of guide grooves 22 and guide strips 21. Then, rotate the rotating sleeve 15 clockwise and drive the multiple sets of screws 14 to rotate through the meshing of the gear ring 16 and multiple sets of gears 17. The multiple sets of screws 14 rotate and engage with the transmission ring 12 through the threaded engagement, driving the push sleeve 11 to slide along the slide groove 10 and push the multiple sets of transmission blocks 7. The multiple sets of transmission blocks 7 slide upward along the inclined groove 5 through the slider 6 and push the clamping plate 8 to engage in the clamping groove 9, clamping the insertion rod 3 and fastening the filter plate 2.
