Description

Technical Field

[0001] The present invention relates to the technical field of server chassis, and in particular to a quick-install structure of a big data server chassis. Background Art

[0002] A server is a specific IT device that provides computing power and runs software applications in a network environment. It provides computing or application services to other clients (such as personal computers, smart phones, ATM machines and other terminal devices) in the network. In order to make the server have higher performance, higher availability and better scalability to meet the needs of large-scale operations and applications, multiple server chassis will be connected in series to expand load balancing and fault tolerance capabilities and distribute them to multiple servers, thereby improving the operating efficiency and stability of the entire system.

[0003] The existing Chinese patent CN221804643U discloses a combined chassis structure of a network security server. By setting a base, a positioning structure is installed inside the base. When the server chassis is spliced ​​and assembled, the chassis is placed on the base, the positioning structure inside the base is adjusted, and the server chassis is locked, thereby improving the splicing efficiency of the modular server body. However, during the use of the above device, the number of servers that can be installed on the base is fixed. When the number of servers that need to be spliced ​​exceeds the number of installation positions on the base, the number of redundant servers cannot be fixed. When the number of servers to be spliced ​​is less than the number of installation positions on the base, the redundant installation positions on the base will occupy the usable area of ​​the computer room, affecting the space utilization rate of the computer room.

[0032] Two symmetrically distributed coil springs 7 are fixedly installed on the outer side of the positioning shaft 6, and the outer end of the coil spring 7 is fixedly connected to the hinge seat 4. Two symmetrically distributed gears 8 are also fixedly installed on the outer side of the shaft rod 3, and the two hinge seats 4 are located between the two gears 8. The right end of the base 2 is located on the lower side of the baffle 9 and is provided with a long straight groove 10, which is used to move the lock hook 5 out from the inside of the base 2.

[0033] The limiting assembly includes a limiting block 11 movably embedded in the base 2, the cross-sectional shape of the limiting block 11 is an isosceles trapezoid, the limiting block 11 is used to block both sides of the lock hook 5, the connection between the limiting block 11 and the lock hook 5 is a movable abutment, a support rod 12 is fixedly embedded at the center of the lower end of the limiting block 11, a positioning plate 13 is movably sleeved on the outer side of the support rod 12, and the connection between the positioning plate 13 and the base 2 is a fixed connection, a spring 14 is movably sleeved on the outer side of the support rod 12, and the two ends of the spring 14 are movably abutted with the base 2 and the positioning plate 13 respectively.

[0034] A retaining ring 15 is fixedly sleeved on the outer side of the support rod 12, and the retaining ring 15 is located on the lower side of the positioning plate 13.

A rotating groove 33 is opened between the two limit blocks 11 at the right end of the base 2, and the rotating groove 33 is connected to the long straight groove 10.

[0035] Working principle: When assembling the chassis body 1, the personnel move chassis B closer to chassis A and align chassis B with chassis A. During the movement of the lock hook 5 with chassis B, the baffle 9 at the right end of chassis A will press against the beveled edge of the lock hook 5 on chassis B, and drive the lock hook 5 to rotate through the beveled edge during the movement of chassis B. After chassis B is docked with chassis A, the lock hook 5 will hook the baffle 9, and the multiple limit assemblies installed on the right end of chassis A will limit the two sides of the lock hook 5, so that the two chassis bodies 1 can be quickly assembled. Not only will it not limit the number of chassis bodies 1 that can be spliced, but there will also be no excess protruding parts that affect the space utilization of the computer room.

[0036] Example 2: Please refer to Figure 3-Figure 7 This embodiment further explains Example 1. The driving assembly includes a spline shaft 18 rotatably mounted inside the base 2 through a bearing, and the spline shaft 18 is located on the right side of the shaft 1 3. Four gears 19 that can move forward and backward are movably sleeved on the outer side of the spline shaft 18, and two of the gears 19 are meshed and connected with the gear 1 8. Limiting rings 20 are fixedly sleeved on both sides of the spline shaft 18 corresponding to the gears 19. The limiting rings 20 are used to limit the moving distance of the gears 19 on the spline shaft 18. A plurality of convex teeth 21 are fixedly mounted on the upper end of the support bar 17, and the gears 19 are meshed and connected with the support bar 17 through the plurality of convex teeth 21.

[0037] The outer side of the spline shaft 18 is movably sleeved with a socket 22 at its center, and the connection between the socket 22 and the base 2 is a fixed connection. Four pins 24 equidistantly distributed in a circle are movably embedded on the inner wall of the socket 22, and a hemispherical portion is provided at one end of the pin 24 close to the spline shaft 18, and a gasket 25 is fixedly connected to the other end of the pin 24 away from the spline shaft 18. The gasket 25 is used to prevent the pin 24 from escaping from the sleeve 23.

[0038] The outer side of the gasket 25 is movably sleeved with a sleeve 23, and the gasket 25 can move inside the sleeve 23. The side of the gasket 25 away from the pin rod 24 is movably abutted with a spring 26, and the end of the spring 26 away from the gasket 25 is movably abutted against the sleeve 23. Four hemispherical slots 34 are opened on the outer side of the spline shaft 18 corresponding to the pin rod 24, and the pin rod 24 is movably engaged with the spline shaft 18 through the hemispherical slots 34, and the hemispherical part of the pin rod 24 is embedded in the hemispherical slots 34 for positioning the spline shaft 18.

[0039] In this embodiment, when a case body 1 among the multiple assembled case bodies 1 fails, the personnel rotates the spline shaft 18 on the failed case body 1 clockwise, and the spline shaft 18 drives the multiple gears 2 19 to rotate clockwise, and the gear 1 8 drives the shaft 1 3 and the lock hook 5 to rotate counterclockwise, and the lock hook 5 rotates counterclockwise and disengages from the other case body 1 through the rotation groove 33, and the gear 2 19 rotates clockwise to drive the support bar 17 to move leftward through the multiple convex teeth 21, and the support bar 17 moves leftward. By disengaging from the ball bearing 16, the limit block 11 can be raised and lowered inside the base 2. At this time, when the faulty chassis is moved forward or backward, the lock hook 5 on the chassis on the right side of the faulty chassis will drive the limit block 11 to move downward through the bevel of the limit block 11. When the lock hook 5 is disengaged from the limit block 11, the limit block 11 will move back and reset under the drive of the compression elastic force of the spring 14. This is conducive to disassembling and assembling only the faulty chassis when a single chassis body 1 fails, without disassembling other assembled chassis bodies 1, which is more convenient to use.

[0040] When the spline shaft 18 rotates, the pin rod 24 is driven by the compression force of the spring 26 to be embedded in the corresponding hemispherical groove 34, so as to position the spline shaft 18.

[0041] Example 3: Please refer to Figure 6 , Figure 8 This embodiment further explains the second embodiment. The adjustment component includes a shaft rod 27 rotatably connected to the base 2 through a bearing, and two symmetrically distributed bidirectional screws 28 are installed on the shaft rod 27. The outer thread of the bidirectional screw 28 is sleeved with two symmetrically distributed connecting blocks 29. The bidirectional screw 28 is used to drive the two connecting blocks 29 to move in opposite directions. A U-shaped seat 30 is fixedly installed on the side of the connecting block 29 close to the second gear 19.

[0042] The U-shaped seat 30 is movably sleeved on the outer side of the gear 2 19, and two symmetrically distributed ball 2s 31 are movably embedded on the inner side of the U-shaped seat 30, and the connection between the ball 2 31 and the gear 2 19 is rolling contact. The ball 2 31 is used to reduce the friction resistance between the U-shaped seat 30 and the gear 2 19. The side of the connecting block 29 away from the U-shaped seat 30 is movably abutted against a baffle 32, and the connection between the baffle 32 and the base 2 is a fixed connection.

[0043] In this embodiment: after the assembly of multiple chassis bodies 1 is completed, the lock hook 5 on the chassis body 1 on the leftmost side will protrude outward, and at this time, the personnel rotates the shaft rod 27 to drive the two bidirectional screws 28 to rotate, and the bidirectional screws 28 rotate to drive the two connecting blocks 29 to move away from each other. Under the action of the U-shaped seat 30, the connecting block 29 will drive the two adjacent gears 2 19 on the spline shaft 18 to move away from each other through the U-shaped seat 30 during the movement. At this time, the two gears 2 19 meshing with the gear 1 8 still maintain the meshing state with the gear 1 8 during the movement, and the two gears 2 19 will be separated from the convex teeth 21 on the support bar 17 when they move away from each other, so that the support bar 17 is still in a supporting state for the ball 1 16, so that the limit block 11 cannot move down and can limit the lock hook 5 on the adjacent chassis body 1. When the two gears 2 19 are away from each other, the rotating spline shaft 18 drives the lock hook 5 to rotate, fold and hide, which can effectively prevent the lock hook 5 from being exposed and deformed by collision.

[0044] When the support bar 17 needs to be moved, the personnel first rotate the lock hook 5 to reset, then rotate the shaft 27 and the two-way screw 28 to drive the plurality of gears 2 19 to move back and reset, and finally move the support bar 17 by rotating the spline shaft 18.
