[0002] A server refers to a computer that manages resources and provides services to users. It is usually divided into file servers, database servers, and application servers. Computers or computer systems that run the above software are also called servers. Servers need to respond to service requests and process them. They have the ability to undertake and guarantee services. The server consists of a processor, hard disk, memory, system bus, etc. It is generally an integrated device, similar to a general computer architecture. It has high requirements in terms of processing power, stability, reliability, security, scalability, manageability, etc. During the use of the server, the server is usually supported and fixed by a server rack.

[0003] However, the traditional server rack has a simple structure and single function. The built-in space of the server rack is fixed and limited, which limits the storage capacity. The storage capacity of the server rack cannot be freely expanded, which has certain defects. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the built-in space of the server rack is fixed and limited, resulting in the storage capacity being restricted and unable to be freely expanded.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an expandable server rack, including a rack body, both ends of the rack body are slidably connected with expansion racks, the bottom end of the expansion rack away from the rack body is fixedly connected with a fixing plate, two screws are threadedly connected on the fixing plate, the top end of the screw is fixedly connected with a rotating handle, the bottom end of the screw is rotatably connected with a support block, and the top ends of both sides of the rack body are provided with limit components that cooperate with the expansion plates.

[0006] As a further improvement of the utility model, a plurality of movable casters are fixedly connected to the bottom of the frame body and locking pieces are arranged on the plurality of movable casters. The number of the movable casters is four and they are distributed in a rectangular shape at the four corners of the bottom of the frame body.

[0007] As a further improvement of the utility model, two T-shaped slide rails are fixedly connected to the bottom of the expansion rack, and a T-shaped slide groove for sliding the T-shaped slide rails is provided on the bottom wall of the rack body.

[0008] As a further improvement of the present invention, a push-pull handle is fixedly connected to a side of the expansion rack away from the rack body.

[0009] As a further improvement of the present invention, the bottom end of the screw is rotatably connected to the support block via a bearing.

[0010] As a further improvement of the utility model, the limit assembly includes a fixed block fixedly connected to the frame body, a connecting rod is passed through the fixed block, a pull block is fixedly connected to the top end of the connecting rod, and a connecting block is fixedly connected to the bottom end of the connecting rod. The connecting block and the fixed block are connected by a spring sleeved on the outside of the connecting rod, the bottom of the connecting block is fixedly connected to the limit block, and a plurality of limit grooves matching the limit block are provided on the top wall of the expansion frame.

[0011] The beneficial effects of the utility model are as follows: both ends of the rack body of the utility model are slidably connected with expansion racks, so that the storage capacity of the rack can be expanded, and then the storage capacity of the server rack can be freely expanded, thereby improving the flexibility and scalability of the rack, and having strong practicality.

It should be understood that the implementation methods described herein are only used to explain this application and are not used to limit this application.

[0021] The utility model provides the following Figure 1-5 An expandable server rack is shown, comprising a rack body 1, with expansion racks 2 slidably connected at both ends of the rack body 1, a fixing plate 3 fixedly connected to the bottom end of the expansion rack 2 away from the rack body 1, two screws 4 threadedly connected to the fixing plate 3, a rotating handle 5 fixedly connected to the top of the screw 4, a supporting block 6 rotatably connected to the bottom end of the screw 4, and a limit assembly 7 cooperating with the expansion plate 2 is provided at the top of both sides of the rack body 1.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, in the utility model, a plurality of movable casters 8 are fixedly connected to the bottom of the frame body 1 and a locking piece is provided on each of the plurality of movable casters 8 for easy fixation and temporary locking. There are four movable casters 8 and they are distributed in a rectangular shape at the four corners of the bottom of the frame body 1, thereby improving the stability of the frame body 1 when moving.

[0023] like Figure 4 As shown, in the utility model, two T-shaped slide rails 9 are fixedly connected to the bottom of the expansion rack 2, and a T-shaped slide groove 10 for the T-shaped slide rails 9 to slide is provided on the bottom wall of the rack body 1, which guides the sliding of the expansion rack 2 and improves the stability of the expansion rack 2 when sliding.

[0024] like Figure 1-5 As shown, in the present invention, a push-pull handle 11 is fixedly connected to the side of the expansion rack 2 away from the rack body 1, so as to facilitate pushing and pulling the expansion board 2 to achieve sliding.

[0025] like Figure 1-4As shown, in the utility model, the screw rod 4 passes through the fixing plate 3, and the fixing plate 3 is provided with a thread groove for the screw rod 4 to pass through. The bottom end of the screw rod 4 is rotatably connected to the support block 6 through a bearing 12, and when the screw rod 4 rotates, it will slide.

[0026] like Figure 5 As shown, the limit assembly 7 in the utility model includes a fixed block 7.1 fixedly connected to the frame body 1, a connecting rod 7.2 is passed through the fixed block 7.1, a pulling block 7.3 is fixedly connected to the top of the connecting rod 7.2, and a connecting block 7.4 is fixedly connected to the bottom of the connecting rod 7.2. The connecting block 7.4 and the fixed block 7.1 are connected by a spring 7.5 sleeved on the outside of the connecting rod 7.2. The bottom of the connecting block 7.4 is fixedly connected to a limit block 7.6. A plurality of limit through grooves 7.7 cooperating with the limit block 7.6 are provided on the top wall of the expansion frame 2. A through hole is provided on the fixed block 7.1 for the connecting rod 7.2 to pass through. The limit assembly 7 can realize the limit fixation of the expansion board 2, thereby improving the overall stability of the frame body 1 and the expansion frame 2.

[0027] Working principle: When the utility model expands the rack body 1, the pull block 7.3 is first pulled upwards, and the limit block 7.6 is driven to slide upwards through the connecting rod 7.2 and the connecting block 7.4. At this time, the spring 7.5 is in a compressed state, and then the push-pull handle 11 is pulled outward to make the expansion frame 2 slide outward, thereby expanding the storage capacity of the rack body 1, and then the pull block 7.3 is released, and the elastic potential energy of the spring 7.5 restores it to its original state, so that the limit block 7.6 moves downward into the limit slot 7.7 on the top wall of the expansion frame 2, realizing the limit fixation of the expansion frame 2, and then the rotating handle 5 is rotated to drive the screw rod 4 to rotate. Since the screw rod 4 is threadedly connected to the fixing plate 3, and the screw rod 4 is rotatably connected to the support block 6 through the bearing 12, when the screw rod 4 rotates, it will slide downward, thereby driving the support block 6 to move downward to contact the ground, thereby supporting the expansion frame 2, thereby improving the overall stability of the rack body 1 and the expansion frame 2.

[0028] The above implementation modes are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the implementation modes of the present invention.
