Description

Technical Field

[0001] This utility model relates to the field of locking mechanism technology, and in particular to a locking mechanism for a server chassis, a server chassis, and a server cabinet. Background Technology

[0002] Server racks are specialized enclosures for housing servers and network equipment, primarily used in server rooms and data centers to provide comprehensive equipment protection and operational assurance. The interior of a server rack features various compartments and mounting holes to install and organize the server's components, protecting not only the hardware but also ensuring stable server operation through a well-designed layout and heat dissipation system.

[0003] Currently, servers typically use water cooling for heat dissipation. For example, Figure 1 As shown, a male connector 1' is located at the rear of the server chassis, and a female connector is located inside the server rack. The male connector at the rear of the server chassis can be plugged into the female connector inside the server rack to ensure the normal operation of the water cooling system within the server chassis. These male and female connectors are typically blind-plug quick-connect types, requiring significant external force to insert the male connector into the female connector and open the water cooling circuit. During operation, the male connector is also continuously subjected to repulsive forces. Therefore, the front of the server chassis must be securely locked to ensure the stability of the water cooling system.

[0004] To ensure proper locking of the front of the server chassis to the front of the server rack, existing technology includes locking mechanisms 2' on both sides of the front of the server chassis, such as... Figure 1 As shown, its locking mechanism is similar to the left and right push handles of a crab's legs. The operator can hold the left and right push handles with both hands and push the server chassis backward to connect the male plug at the rear of the server chassis with the female plug inside the server rack. Then, the left and right push handles are brought forward in a lever-like manner, so that the left and right push handles are connected to the server rack under the action of the shoulder stop block 3' at the front of the server rack, which can prevent the male plug and female plug from disconnecting.

[0007] 2) Inconvenient operation: With existing technology, server chassis must be pushed into the server rack with both hands, like crab legs, and cannot be pushed in with one hand.

[0008] 3) Relatively low reliability: in the prior art, when the server case is pushed into the cabinet, the left and right push handles on the server case can be loosened from the cabinet due to improper human operation or severe external force, causing the sudden disconnection of the cooling water path, affecting the reliability of the connection between the server case and the server cabinet;

[0009] 4) High manufacturing cost: according to the structure described in the prior art, a hardware stamping die must be used for forming, and a material with high strength must be used for manufacturing, the assembly structure is complex, and the manufacturing cost is high. Utility model content

[0059] Example 2:

[0060] A server chassis, such as Figure 5 As shown, the system includes the locking mechanism 51 of Embodiment 1, as well as a chassis housing 52, a power module, and water-cooling piping. The power module and water-cooling piping are both housed within the chassis housing 52, and the locking mechanism 51 is located at the front end of the chassis housing 52. Specifically, the chassis housing 52 serves to support the corresponding modules, and the chip modules and water-cooling piping are integrated onto the chassis housing 52, implementing their respective functions. It should be noted that the water-cooling piping is used to dissipate the heat generated by the power module. The locking mechanism 51, located at the front end of the chassis housing 52, is used to secure the server chassis to the rack within the server rack.

[0061] As an optional implementation method, such as Figure 5 As shown, the water-cooling piping includes a male connector 53, which is located at the rear end of the chassis housing 52 and is used to connect to an external connector. Specifically, the water-cooling piping includes a male connector 53 located at the rear end of the chassis housing 52 and water-cooling pipes located above the chassis housing 52.
