The cabinet is a key equipment in the network server. Electronic equipment, power supplies, etc. are placed in the cabinet to protect them and provide a more suitable working environment for them.

[0003] The size of existing cabinets cannot be adjusted. If the cabinet width is fixed and cannot be fine-tuned according to the different sizes of servers, it may lead to insufficient space or compactness when installing longer servers. Additional adapters or modifications may be required, which increases costs and time consumption. Further improvement is needed. For this reason, a campus network server terminal cabinet is proposed. Summary of the invention

[0004] The main purpose of the present invention is to provide a campus network server terminal cabinet, which can effectively solve the problems in the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A campus network server terminal cabinet comprises a cabinet body, which is a concave structure. A universal wheel is installed at the lower end of the cabinet body. The upper inner wall and the lower inner wall of the cabinet body are slidably connected with two movable racks which are symmetrically distributed on the left and right sides. A plurality of support plates which are distributed in a linear array are installed on the rear inner wall of the cabinet body. Two movable plates which are symmetrically distributed on the left and right sides are movably sleeved inside the plurality of support plates. The left movable plate and the right movable plate are fixedly connected with the left inner wall and the right inner wall of the two movable racks respectively. The two movable racks can move away from or close to each other, so as to adjust the volume inside the cabinet body.

[0008] Preferably, the two moving blocks are fixedly connected in two sliding grooves respectively.

[0009] Preferably, a rectangular groove is provided at the upper end of the movable plate, and a plurality of lifting plates distributed in a linear array are slidably connected in the rectangular groove, and two guide rods symmetrically distributed front and back are installed at the lower ends of the plurality of lifting plates, and a screw rod is movably connected to the middle part of the lower ends of the plurality of lifting plates.

[0010] Preferably, the lower end of the support plate is provided with two grooves symmetrically distributed left and right, the lower end thread of the screw rod is inserted into the lower end of the movable plate and extends into the groove, and the lower end of the guide rod movably passes through the lower end of the movable plate and extends into the groove.

[0011] Preferably, a plurality of through slots are provided at the rear end of the cabinet.

[0028] like Figure 1-5As shown, a campus network server terminal cabinet comprises a cabinet 1, which is a concave structure. A universal wheel 2 is installed at the lower end of the cabinet 1. The upper inner wall and the lower inner wall of the cabinet 1 are slidably connected to two left-right symmetrically distributed moving frames 3. A plurality of support plates 4 distributed in a linear array are installed on the rear inner wall of the cabinet 1. Two left-right symmetrically distributed moving plates 5 are movably sleeved inside the plurality of support plates 4. The left moving plate 5 and the right moving plate 5 are respectively fixedly connected to the left inner wall and the right inner wall of the two moving frames 3. The two moving frames 3 can move away from or close to each other to adjust the volume inside the cabinet 1. Through the arrangement of the cabinet 1, the universal wheel 2, the moving frame 3, the support plate 4 and the moving plate 5, when in use, the concave structure design of the cabinet 1 provides a relatively closed and regular space for the installation of internal components and the placement of the server. The universal wheel 2 is installed at the lower end of the cabinet 1, so that the whole Each cabinet has the ability to move flexibly. No matter in the initial layout stage of the campus network computer room or in the subsequent adjustment of the cabinet position due to equipment maintenance, computer room renovation, etc., the cabinet can be easily pushed to the designated position. The two mobile racks 3 are slidably connected to the upper inner wall and the lower inner wall of the cabinet 1, and a number of support plates 4 are installed in a linear array on the rear inner wall of the cabinet 1, providing a stable support platform for the server. The number and spacing of the support plates 4 can be designed according to the size and weight distribution of common servers to ensure that the weight of the server can be evenly borne to avoid local stress concentration from damaging the structure of the cabinet 1. The two mobile plates 5 movably sleeved inside each support plate 4, on the one hand, play the role of connecting the mobile racks 3, and on the other hand, during the movement of the mobile racks 3, the mobile plates 5 can slide freely in the support plates 4, thereby ensuring the linkage and flexibility of the entire structure.

[0029] Furthermore, the lower inner walls of the two movable frames 3 are each provided with a slide groove 7, and the lower inner wall of the cabinet 1 is installed with two bearing seats 8 symmetrically distributed front and back, and the two bearing seats 8 are movably connected in the two slide grooves 7 respectively, and the ends of the two bearing seats 8 close to each other are movably connected with a positive and negative threaded rod 9, and the outer surfaces of the positive and negative threaded rod 9 are commonly threadedly sleeved with two movable blocks 10 symmetrically distributed left and right. Through the arrangement of the slide groove 7, the bearing seat 8, the positive and negative threaded rod 9 and the movable block 10, in the initial state, the two movable frames 3 are in a relatively close position, and the slide groove 7 on the lower inner wall thereof cooperates with the bearing seat 8 installed on the lower inner wall of the cabinet 1. On the one hand, the bearing seat 8 can slide smoothly in the slide groove 7, and on the other hand, it provides stable support and The forward and reverse threaded rods 9 pass through the two moving blocks 10 and form a threaded connection relationship with the moving blocks 10. The moving blocks 10 are respectively fixed in the two slide grooves 7. This structural design enables the rotational movement of the forward and reverse threaded rods 9 to be converted into the linear movement of the moving blocks 10, thereby driving the moving frame 3 connected thereto to move. When the server is longer in size, the operator uses an adapted tool to act on the part of the forward and reverse threaded rods 9 with nuts. Due to the special thread structure of the forward and reverse threaded rods 9, the threads at both ends are in opposite directions. When the tool applies torque to cause the forward and reverse threaded rods 9 to start rotating, according to the principle of thread transmission, the two moving blocks 10 sleeved on the forward and reverse threaded rods 9 will produce linear motion in opposite directions. If the forward and reverse threaded rods 9 are rotated in the same direction, the two moving blocks 10 will produce linear motion in opposite directions. As the clockwise rotation rotates, one of the moving blocks 10 will move to the left along the thread, while the other moving block 10 will move to the right, and the moving speeds and distances of the two moving blocks 10 are the same. As the two moving blocks 10 move away from each other, since the moving blocks 10 are respectively fixedly connected to the slide grooves 7 of the two moving frames 3, the moving blocks 10 will apply a horizontal thrust to the moving frames 3. Under the action of this thrust, the moving frames 3 begin to slide smoothly to both sides on the sliding tracks of the upper and lower inner walls of the cabinet 1, and the left and right inner walls of the moving frames 3 are respectively fixedly connected to the moving plates 5. Therefore, the movement of the moving frames 3 will drive the moving plates 5 to move synchronously. At this time, the moving plates 5 will gradually extend outward from the state originally set inside the support plates 4, so that the cabinet 1, which was originally relatively The smaller space can be expanded in the left and right directions. When the mobile frame 3 and the mobile plate 5 are moved to the appropriate positions, enough space is formed inside the cabinet 1 to accommodate a longer server. At this time, the server is placed on the supporting plane formed by the mobile plate 5 and the supporting plate 4, and the corresponding fixing and line connection operations are performed. The entire operation process can realize the flexible adjustment of the internal space of the cabinet 1 only by rotating the forward and reverse threaded rods 9. There is no need to find an additional suitable server adapter or perform complicated modification operations on the cabinet. This not only greatly reduces the additional cost expenditure caused by the mismatch of server sizes, including the adapter procurement cost, modification materials and labor costs, but also saves a lot of time for finding adaptation solutions and performing modification construction.The applicability of the campus network server terminal cabinet to servers of different sizes has been significantly improved, which can better meet the diverse server installation requirements in the campus network environment and ensure the efficient and stable operation of the campus network system.

[0030] Furthermore, the two moving blocks 10 are respectively fixedly connected in the two slide grooves 7. Through the setting of the moving blocks 10, when in use, because the moving blocks 10 are fixedly connected to the slide grooves 7, the movement of the moving blocks 10 will directly drive the moving frame 3 to move. The moving block 10 moving to the left will pull the connected moving frame 3 to slide to the left, and the moving block 10 moving to the right will push its corresponding moving frame 3 to slide to the right. As the two moving frames 3 move away from each other, the moving plate 5 fixedly connected to the left and right inner walls of the moving frame 3 will gradually extend from the supporting plate 4, so that the internal space of the cabinet is effectively increased, so that it can easily accommodate servers with longer lengths, and the space can be reduced and adjusted by rotating the forward and reverse threaded rods 9 in the opposite direction to meet the installation requirements of servers of different sizes, thereby greatly improving the versatility and practicality of the cabinet.

[0031] Furthermore, a rectangular groove 14 is provided at the upper end of the movable plate 5, and a plurality of lifting plates 15 distributed in a linear array are slidably connected in the rectangular groove 14. Two guide rods 12 symmetrically distributed front and back are installed at the lower ends of the plurality of lifting plates 15. The middle parts of the lower ends of the plurality of lifting plates 15 are movably connected with screws 13. The lower end of the support plate 4 is provided with two grooves 11 symmetrically distributed left and right. The lower end of the screw 13 is threadedly inserted into the lower end of the movable plate 5 and extends into the groove 11. The lower end of the guide rod 12 movably passes through the lower end of the movable plate 5 and extends into the groove 11. Through the arrangement of the groove 11, the guide rod 12, the screw 13, the rectangular groove 14, and the lifting plate 15, in the initial state, the lifting plate 15 is stored on the movable plate 5 The guide rod 12 penetrates the lower end of the movable plate 5 and extends into the groove 11 at the lower end of the support plate 4. The screw 13 is also threadedly inserted into the movable plate 5 and extends into the groove 11. At this time, the upper surface of the lifting plate 15 is lower than the upper surface of the support plate 4, forming a placement plane drop caused by the height difference between the movable plate 5 and the support plate 4. When the movable plate 5 extends out from the support plate 4 to meet the placement requirements of a longer server, the placement plane needs to be leveled due to the height difference. At this time, the operator manually rotates the screw 13. Since the screw 13 and the movable plate 5 are in a threaded connection relationship, and the lower end of the screw 13 is located in the groove 11 and is subject to a certain limit, when the screw 13 rotates, according to the thread transmission principle In principle, the screw 13 will produce a linear motion along its axial direction during the rotation process, and the linear motion of the screw 13 drives the lifting plate 15 movably connected thereto to slide up and down along the rectangular groove 14. In this process, the guide rod 12 can play a stabilizing and guiding role. The guide rod 12 slides up and down in the movable plate 5 and the groove 11 along its axial direction, limiting the lifting plate 15 to be able to move smoothly in the vertical direction, preventing it from tilting, shaking or getting stuck during the rotation of the screw 13, ensuring that the lifting plate 15 can move up or down accurately and stably. As the screw 13 rotates, the lifting plate 15 gradually moves upward. When it rotates to a suitable angle and number of turns, the upper end of the lifting plate 15 will gradually rise to the position aligned with the support The upper end of the support plate 4 is flush with the position, thereby filling the height difference between the movable plate 5 and the support plate 4, forming a complete, horizontal server placement plane. Then, according to the same operating steps, the other screws 13 are rotated in turn to make the corresponding lifting plates 15 rise to the same height. In this way, the server can be stably placed on the horizontal placement plane formed by the support plate 4 and the lifting plate 15. Through this precise leveling operation, the probability of failures such as uneven force on internal components of the server, loose connections, and abnormal signal transmission caused by unbalanced equipment placement is effectively reduced, providing a reliable installation foundation for the stable operation of the server in the cabinet, and ensuring the continuous and stable operation of the campus network system.

[0032] Furthermore, a plurality of through slots 6 are provided at the rear end of the cabinet 1, and dust filters are installed on the inner surfaces of the through slots 6. Through the arrangement of the through slots 6, when in use, the server will generate a large amount of heat during operation, which needs to be dissipated through air convection. The through slots 6 provide a passage for air circulation between the inside and outside of the cabinet 1. When the server is working, the temperature of the hot air inside increases and the density decreases, and it will naturally flow upward. Due to the rising movement of the hot air, a low-pressure area will be formed inside the cabinet 1. At this time, the external cold air will enter the cabinet 1 through the through slots 6 with dust filters under the action of the air pressure difference. The incoming cold air will flow through the server, absorb the heat emitted by the server, and become hot air before being discharged from the cabinet 1 through other vents, thereby forming a complete air convection cycle, which effectively To lower the temperature inside the cabinet 1 and ensure that the server runs in a suitable temperature environment, and to prevent problems such as performance degradation or hardware damage due to overheating, the dust filter is installed on the inner surface of the through slot 6. Its main function is to prevent dust, debris and other impurities from entering the cabinet 1. When external air enters the cabinet 1 through the through slot 6, the air must pass through the dust filter. The mesh size of the dust filter is usually designed to allow air molecules to pass freely, but to intercept dust particles. When dust particles try to follow the air into the cabinet 1, they will be blocked by the fibers of the dust filter or the structure of the filter. Over time, a certain amount of dust will accumulate on the dust filter. Regularly cleaning or replacing the dust filter can ensure that it always maintains good dustproof performance, thereby protecting the server and other equipment inside the cabinet 1 from dust.

[0033] Furthermore, a fixing rod 16 is fixedly connected to the left front end of the left movable rack 3 and the rear front end of the right movable rack 3, and a telescopic net 17 is installed at one end of the two fixing rods 16 close to each other, and a moving rod 18 is installed at one end of the two telescopic nets 17 close to each other, and the upper and lower ends of the two moving rods 18 are respectively slidably connected to the upper inner wall and the lower inner wall of the cabinet 1. Through the arrangement of the fixing rod 16, the telescopic net 17 and the moving rod 18, when in use, the telescopic net 17 is in a relatively contracted state. Since the moving rod 18 is slidably connected to the upper inner wall and the lower inner wall of the cabinet 1, and the fixing rod 16 is fixedly connected to the movable rack 3, the telescopic net 17 is fixed at a specific position inside the cabinet 1, forming a preliminary protective barrier, which can prevent external dust, debris and small objects from accidentally entering the interior of the cabinet 1 to a certain extent, avoid direct collision, pollution or interference with equipment such as servers, and protect the normal operation of the server and the stability of internal line connections. After the server size is moved left and right to adjust the internal space of the cabinet 1, the original telescopic net 17 may not be able to completely cover or adapt to the new internal space layout. At this time, the operator manually pulls the moving rod 18 to move left and right. Due to the sliding connection between the moving rod 18 and the inner wall of the cabinet 1, the moving rod 18 can move smoothly in the horizontal direction. The movement of the moving rod 18 will drive the telescopic net 17 to extend or contract. When the moving rod 18 is pulled to both sides, the telescopic net 17 will gradually unfold along the direction of the fixed rod 16, and its mesh material will be stretched, the mesh will become larger, and the coverage area will increase; conversely, when the moving rod 18 moves toward each other, the telescopic net 17 will shrink, the mesh will become smaller, and the coverage area will decrease. In this way, the telescopic net 17 can be adaptively adjusted according to the adjusted position of the moving frame 3 and the changes in the internal space of the cabinet 1, so as to always maintain effective protection for the server area inside the cabinet 1 and ensure the safety and stable operation of the internal equipment of the campus network server terminal cabinet.

[0034] Furthermore, a rubber buffer pad is installed on the upper surface of the lifting plate 15. Through the setting of the lifting plate 15, when the server is placed on the plane formed by the lifting plate 15 and the support plate 4 during use, the weight of the server itself will generate pressure on the placement plane. The rubber buffer pad is installed on the upper surface of the lifting plate 15. Since rubber has good elasticity, when it is subjected to the pressure of the server, the rubber buffer pad will undergo elastic deformation. This elastic deformation can absorb and disperse part of the weight pressure of the server, avoiding hard contact between the bottom of the server and the surface of the lifting plate 15. When the cabinet is subjected to slight vibration, the rubber buffer pad will buffer these vibrations through its own elastic restoring force, thereby reducing the amplitude of the vibration transmitted to the server.

[0035] Furthermore, guide rails are installed on the inner walls of both sides of the rectangular groove 14, and both sides of the lifting plate 15 are slidably connected to the guide rails through sliders. Through the arrangement of the rectangular groove 14 and the lifting plate 15, when in use, the cooperation between the guide rails and the sliders also enhances the stability of the lifting plate 15 during movement. After the server is placed on the lifting plate 15 and the support plate 4, additional force may be exerted on the lifting plate 15 due to uneven weight distribution of the server or slight external vibration. At this time, the connection structure of the guide rails and the sliders can effectively resist these external forces and prevent the lifting plate 15 from shifting or shaking. The sliders fit tightly along the guide rails, so that the lifting plate 15 can still maintain a stable position and state when subjected to vertical loads and slight interference forces in other directions, thereby ensuring the stability and safety of the server installation.

[0036] Working principle: The concave structural design of the cabinet 1 provides a relatively closed and regular space for the installation of internal components and the placement of servers. The universal wheels 2 are installed at the lower end of the cabinet 1, so that the entire cabinet has the ability to move flexibly. Whether in the initial layout stage of the campus network room or in the subsequent adjustment of the cabinet position due to equipment maintenance, room renovation, etc., the cabinet can be easily pushed to the designated position. The two mobile frames 3 are slidably connected to the upper and lower inner walls of the cabinet 1, and several support plates 4 are installed in a linear array on the rear inner wall of the cabinet 1, providing a stable support platform for the server. The number and spacing of the support plates 4 can be designed according to the size and weight distribution of common servers to ensure that the weight of the server can be evenly carried to avoid local The internal stress concentration causes damage to the structure of the cabinet 1. The two movable plates 5 movably sleeved inside each support plate 4, on the one hand, play the role of connecting the movable frame 3, on the other hand, during the movement of the movable frame 3, the movable plate 5 can slide freely in the support plate 4, ensuring the linkage and flexibility of the entire structure. In the initial state, the two movable frames 3 are in a relatively close position, and the slide groove 7 on the lower inner wall thereof cooperates with the bearing seat 8 installed on the lower inner wall of the cabinet 1. On the one hand, the bearing seat 8 can slide smoothly in the slide groove 7, and on the other hand, it provides a stable support and rotation connection point for the positive and negative threaded rod 9. The positive and negative threaded rod 9 passes through the two movable blocks 10 and forms a threaded connection relationship with the movable block 10. The movable block 10 is respectively fixed in the two slide grooves 7. This structural design enables the rotational motion of the positive and negative threaded rod 9 to be converted into the linear motion of the moving block 10, thereby driving the connected moving frame 3 to move. When the server is longer, the operator uses an adapted tool to act on the part of the positive and negative threaded rod 9 with a nut. Due to the special thread structure of the positive and negative threaded rod 9, the threads at both ends are in opposite directions. When the tool applies torque to cause the positive and negative threaded rod 9 to start rotating, according to the principle of thread transmission, the two moving blocks 10 sleeved on the positive and negative threaded rod 9 will produce linear motion in opposite directions. If the positive and negative threaded rod 9 rotates clockwise, one of the moving blocks 10 will move to the left along the thread, while the other moving block 10 will move to the right, and the two moving speeds are the same and the distances are equal. As the two moving blocks 10 move away from each other, since the moving blocks 10 are respectively fixedly connected to the slide grooves 7 of the two moving racks 3, the moving blocks 10 will apply a horizontal thrust to the moving rack 3. Under the action of this thrust, the moving rack 3 begins to slide smoothly to both sides on the sliding tracks of the upper inner wall and the lower inner wall of the cabinet 1, and the left and right inner walls of the moving rack 3 are respectively fixedly connected to the moving plate 5. Therefore, the movement of the moving rack 3 will drive the moving plate 5 to move synchronously. At this time, the moving plate 5 will gradually extend outward from the state originally set inside the support plate 4, so that the originally relatively small space inside the cabinet 1 can be expanded in the left and right directions. When the moving rack 3 and the moving plate 5 are moved to the appropriate position, sufficient space is formed inside the cabinet 1 to accommodate longer servers.At this time, the server is placed on the supporting plane formed by the movable plate 5 and the supporting plate 4, and the corresponding fixing and line connection operations are performed. The entire operation process can realize the flexible adjustment of the internal space of the cabinet 1 only by rotating the positive and negative threaded rods 9, and there is no need to find an additional suitable server adapter or perform complicated modification operations on the cabinet. This not only greatly reduces the additional cost expenditure caused by the mismatch of server sizes, including adapter procurement costs, modification materials and labor costs, but also saves a lot of time for finding adaptation solutions and performing modification construction, which significantly improves the applicability of the campus network server terminal cabinet to servers of different sizes, and can better meet the diverse server installation needs in the campus network environment, and ensure the campus network system The lifting plate 15 is arranged in a rectangular groove 14 at the upper end of the movable plate 5, the guide rod 12 passes through the lower end of the movable plate 5 and extends into the groove 11 at the lower end of the support plate 4, and the screw 13 is also threadedly inserted into the movable plate 5 and extends into the groove 11. At this time, the upper surface of the lifting plate 15 is lower than the upper surface of the support plate 4, forming a placement plane drop caused by the height difference between the movable plate 5 and the support plate 4. When the movable plate 5 extends out from the support plate 4 to meet the placement requirements of a longer server, the placement plane needs to be leveled due to the height difference. At this time, the operator manually rotates the screw 13. Since the screw 13 and the movable plate 5 are in a threaded connection relationship, and the lower end of the screw 13 is located in the groove 11 and is subject to a certain limit, when the screw When the rod 13 rotates, according to the principle of thread transmission, the screw 13 will produce linear motion along its axial direction during the rotation process, and the linear motion of the screw 13 drives the lifting plate 15 movably connected thereto to slide up and down along the rectangular groove 14. In this process, the guide rod 12 can play a stabilizing and guiding role. The guide rod 12 slides up and down in the movable plate 5 and the groove 11 along its axial direction, limiting the lifting plate 15 to only be able to move smoothly in the vertical direction, preventing it from tilting, shaking or getting stuck during the rotation of the screw 13, and ensuring that the lifting plate 15 can move up or down accurately and stably. As the screw 13 rotates, the lifting plate 15 gradually moves upward. When it rotates to a suitable angle and number of turns, the upper end of the lifting plate 15 will gradually rise to the position aligned with the support The upper end of the support plate 4 is flush with the position, thereby filling the height difference between the movable plate 5 and the support plate 4, forming a complete and horizontal server placement plane. Then, according to the same operating steps, the other screw rods 13 are rotated in turn to make the corresponding lifting plates 15 rise to the same height, so that the server can be stably placed on the horizontal placement surface formed by the support plate 4 and the lifting plate 15. Through this precise leveling operation, the probability of uneven force on the internal parts of the server, loose connections, abnormal signal transmission and other failures caused by unbalanced equipment placement is effectively reduced, providing a reliable installation foundation for the stable operation of the server in the cabinet, and ensuring the continuous and stable operation of the campus network system. The telescopic network 17 is in a relatively contracted state.Since the moving rod 18 is slidably connected to the upper inner wall and the lower inner wall of the cabinet 1, and the fixed rod 16 is fixedly connected to the moving frame 3, the telescopic net 17 is fixed at a specific position inside the cabinet 1, forming a preliminary protective barrier, which can prevent external dust, debris and small objects from accidentally entering the cabinet 1 to a certain extent, avoid direct collision, pollution or interference with equipment such as servers, and protect the normal operation of the server and the stability of internal line connections. When the moving frame 3 moves left and right to adjust the internal space of the cabinet 1 according to the size of the server, the original telescopic net 17 may not be able to completely cover or adapt to the new internal space layout. At this time, the operator manually pulls the moving rod 18 to move left and right. Since the moving rod 18 is connected to the cabinet 1, the moving rod 18 can move smoothly in the horizontal direction, and the movement of the moving rod 18 will drive the telescopic net 17 to extend or contract. When the moving rod 18 is pulled to both sides, the telescopic net 17 will gradually expand along the direction of the fixed rod 16, and its mesh material will be stretched, the mesh will become larger, and the coverage area will increase; conversely, when the moving rod 18 moves toward each other, the telescopic net 17 will shrink, the mesh will become smaller, and the coverage area will decrease. In this way, the telescopic net 17 can be adaptively adjusted according to the adjusted position of the moving frame 3 and the changes in the internal space of the cabinet 1, always maintaining effective protection of the server area inside the cabinet 1, and ensuring the safety and stable operation of the internal equipment of the campus network server terminal cabinet.
