Description

Technical Field

[0001] The present invention relates to the technical field of switches, and in particular to a switching device. Background Art

[0002] SDN network originates from the fact that current switches, routers, network protocols and segmentation tools cannot meet the demand for connectivity. It allows application services to enter the control layer of abstract network data flow in real time, making automatic instantiation programming and control possible, and also allows customized data flow to be directly transmitted between application services, between applications and their data sources and data sets, and between applications and end users, thus making network security of great importance.

[0003] A server data exchange network security device disclosed by publication number CN110366053A in the prior art includes a mounting seat, a fixing hole and a protective shell are arranged on the mounting seat, the fixing hole is located on the left and right sides of the mounting seat, the protective shell is fixedly connected to the upper end of the mounting seat, an adjusting bolt and a fixing column are arranged on the protective shell, the adjusting bolt is movably connected to the left and right sides of the outer surface of the protective shell, the fixing column is fixedly connected to the left and right sides of the inside of the protective shell, and a locking pad is arranged on the adjusting bolt, which enhances the flexibility of the switch body when moving and reduces the The friction between the switch body and the protective shell, but its overall structure is fragile, and the shell is mostly made of plastic material, and there are multiple precision electronic components inside. The protective structure proposed by the above scheme is difficult to ensure the integrity of the overall structure when it is subjected to severe external pressure, which is very likely to cause the structure of the network switching device to deform or even be damaged; in addition, because a large number of electronic components are arranged therein, long-term high-efficiency operation is very likely to cause high-temperature heat to be generated inside it. The existing network switching equipment has only through-hole heat dissipation holes, which is difficult to meet the heat dissipation needs, so it has to run under load in a high-temperature environment, which is very likely to cause short circuit and burning. Summary of the invention

The cold compress mechanism includes a compression plate 4 slidably sleeved in the upper encapsulation housing 1, and a driving rack 5 is fixedly installed on the compression plate 4. A transmission rotating shaft 6 is rotatably installed in the upper encapsulation housing 1 and is in transmission connection with the driving rack 5, and an eccentrically arranged boosting cam 8 is integrally connected to the transmission rotating shaft 6.

The other end of the sealing cavity 9 is threadedly connected to a rubber water bag 12 that is in movable contact with the switch body. The boosting cam 8 is arranged by using a driven gear 7 meshed with the driving rack 5, so as to drive the power piston 10 slidably sleeved in the sealing cavity 9, so that when the upper encapsulation housing 1 is subjected to external extrusion, low-temperature coolant enters the rubber water bag 12 to perform low-temperature cold compression on the switch body.

[0030] Refer to the attached drawings of the specification Figure 1 And the attached drawings Figure 3A protective mechanism is provided in the lower packaging shell 2 and is connected to the cold compress mechanism for anti-collision protection of the switch body. It is further described that the protective mechanism includes a second open cavity 14 opened in the lower packaging shell 2 and a first open cavity 13 for movably sleeved with the driving rack 5. A second spring 16 and a guide block 15 welded together are slidably sleeved in the second open cavity 14. A support rod 17 is connected to the pin on the second guide block 15, and a lifting support plate 18 for supporting the switch body is installed on the pin on the second support rod 17.

[0031] A driven gear 7 meshing with the driving rack 5 is keyed on the transmission shaft 6, and a first spring 11 welded to the upper packaging shell 1 is fixedly provided on the powerful piston 10. Under the pulling force of the first spring 11, the powerful piston 10 resets itself, so that the low-temperature coolant in the rubber water bag 12 flows back into the sealing chamber 9.

[0035] The present invention can be explained by the following operation mode:

[0036] Place the switch body on the lifting support plate 18 of the lower encapsulation housing 2;

[0037] Corresponding to the upper encapsulation housing 1 and the lower encapsulation housing 2, by pressing on the limiting block 23 on the guide rod 21, so that the limiting block 23 is sleeved in the card slot 19, and tightening the screw in the threaded hole to limit and fix the upper encapsulation housing 1 and the lower encapsulation housing 2;

[0038] When the pressure plate 4 outside the upper encapsulation housing 1 is extruded, the pressure plate 4 drives the driving rack 5 to extend into the first opening cavity 13. The driving rack 5 drives the transmission rotating shaft 6 to rotate through the driven gear 7. The transmission rotating shaft 6 drives the supercharging cam 8 to rotate, and the supercharging cam 8 pressurizes the powerful piston 10;

[0039] The powerful piston 10 extrudes the low-temperature coolant in the sealing cavity 9, so that the low-temperature coolant enters the rubber water bag 12 to apply cold compress to the switch body;

[0040] The driving rack 5 that enters the first opening cavity 13 drives the driving wedge block 501 to extend synchronously, so as to extrude the driven wedge block 1601, so that the guide block 15 pressurizes the second spring 16. The guide block 15 drives the lifting support plate 18 to move up and down through the support rod 17 to provide an up and down movable supporting effect for the switch body.
