Technical Field
[0001] The utility model relates to the technical field of server installation structures, in particular to a guide rail device for a rack-mounted server. Background Technique
[0002] Cloud computing is a computing model based on the Internet, which allows users to access and store data through the network, as well as use various computing services, such as servers, storage, application programs, and analysis services, etc. The core idea of cloud computing is to uniformly manage and schedule a large number of computing resources to form a resource pool and provide services to users on demand. The servers of the cloud computing platform are installed on the rack through a guide rail device.
[0003] The guide rail is divided into an inner rail and an outer rail. The inner rail is installed on the side of the server, while the outer rail is fixed on the rack. After the inner rail and the outer rail are installed in place, the server is lifted so that the inner rail on its side is inserted into the chute of the outer rail. Since the size of the chute of the outer rail is adapted to the outer size of the inner rail and the server is heavy, it is not convenient to quickly align the inner rail with the chute and insert it into the outer rail after lifting, and the inner rail is prone to jamming problems during the insertion process. Therefore, we propose a guide rail device for a rack-mounted server. Summary of the Utility Model

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a guide rail device for a rack-mounted server, including an inner rail 1 and an outer rail 2. The middle part of the inner rail 1 is bent towards one side, and the bent part towards the side can just tightly adhere to the side surface of the server chassis. A plurality of bayonets 11 are provided on the surface of the inner rail 1 and are evenly distributed on the surface of the inner rail 1. The buckle provided on the side of the chassis can be inserted into the bayonet 11 and then pushed to fasten the inner rail 1 to the side surface of the chassis. A plurality of through holes 12 are evenly provided on the surface of the inner rail 1, and the through holes 12 are located between the bayonets 11 on the surface of the inner rail 1. After fastening the inner rail 1, the through holes 12 are aligned with the screw holes on the surface of the chassis, and then bolts can be passed through the through holes 12 and screwed into the screw holes to lock the inner rail 1 on both sides of the chassis.
[0026] Fixing plates 3 are fixed to both the front and rear surfaces of the back of the outer rail 2. The front and rear fixing plates 3 are of the same size. The total length of the outer rail 2 is adapted to the longitudinal depth of the frame, so that the outer rail 2 is longitudinally placed on both sides inside the frame, and the fixing plates 3 are in contact with the reserved hole positions at the front and rear of the frame. Three screw openings 31 are evenly formed on the surface of the fixing plate 3, and each screw opening 31 is aligned with a reserved opening respectively. Then, bolts are passed through the aligned reserved holes at the upper and bottom screw openings 31 and screwed into the screw openings 31 to realize the installation and fixation of the outer rail 2. The installation heights of the two outer rails 2 are the same.
[0027] A chute 21 with a size larger than that of the inner rail 1 is formed inside the outer rail 2. An upper opening 22 is formed above the front end of the outer rail 2, and the upper opening 22 is communicated with the chute 21 inside the outer rail 2. When the server is lifted to drive the inner rail 1 to rise, the rear end of the inner rail 1 can be quickly supported and placed in the chute 21 inside the outer rail 2 through the upper opening 22. Guide wheels 4 are installed on both the upper and lower surfaces inside the chute 21. The guide wheels 4 are rotatably installed in the chute 21 through bearings. A plurality of guide wheels 4 are provided and evenly distributed. A guide groove 41 is formed around the outer ring of the guide wheel 4. In addition, inclined edges 13 are provided above and below the rear end of the inner rail 1, and the slopes of the upper and lower inclined edges 13 are the same. Then, when the server and the inner rail 1 are pushed backward, the inner rail 1 can be quickly pushed and slid into the chute 21 above and below through the inclined edges 13 and guided into the guide groove 41 of the guide wheel 4, which is convenient for the inner rail 1 to slide inside the chute 21 of the outer rail 2 under the guiding action of the guide wheel 4.
[0028] A side opening 23 is formed at the middle position of the side of the outer rail 2, and the side opening 23 is communicated with the chute 21 of the outer rail 2. The bent part of the inner rail 1 passes through the side opening 23 to the outside, keeping the connection between the inner rail 1 and the server chassis unaffected.
[0029] When in use, first hold the two inner rails 1 and place them against both sides of the server chassis, so that the fasteners on the outer surface of the chassis are snapped into the bayonet 11, and the screw holes on the surface of the chassis are aligned with the through holes 12. Then, pass a bolt through the through hole 12 and screw it into the screw hole to fix the inner rail 1 on both sides of the chassis. Then, hold the two outer rails 2. The outer rails 2 are placed between the front and rear ends on both sides inside the chassis. The screw threads 31 on the surface of the fixing plate 3 are aligned with the reserved holes on the surface of the chassis, and the bolt is passed through the reserved hole and screwed into the screw holes on the upper and bottom surfaces above the fixing plate 3, so as to fix the outer rail 2 to the rack. The heights of the two outer rails 2 on both sides are kept the same. Then, lift the server so that the rear ends of the two inner rails 1 on both sides are close to the upper part of the outer frame. The rear end of the inner rail 1 is directly supported by the upper opening 22 to the front end of the outer rail 2, and the bottom of the inner rail 1 is supported in the lower chute 21 of the outer rail 2. Then, push the server backward to drive the inner rail 1 to move backward. Under the guiding action of the inclined piece at the rear end of the inner rail 1, it is easy for the end of the inner rail 1 to be supported and slide into the guide groove 41 of the guide wheel 4 in the chute 21, and the upper part of the inner rail 1 is snapped into the guide groove 41 of the upper guide wheel 4. Then, the server can be pushed backward to place the inner rail 1 inside the outer rail 2 and slide backward under the supporting and guiding action of the guide wheel 4 until the front side of the server touches the front end of the rack. Then, a bolt can be passed through both sides of the front end of the server and screwed into the screw thread 31 in the middle position to lock the server.
