[0002] With the rapid development of computer technology, network systems have become one of the indispensable infrastructures in modern society. In network systems, the host chassis, as a core component, is responsible for carrying and protecting key hardware components such as processors, memory, and hard disks. Its security and stability are directly related to the operating efficiency and data security of the entire network system.

[0003] Traditional host chassis design often focuses on hardware integration and heat dissipation efficiency improvement, while the protection of rear interfaces such as power sockets and transmission sockets is relatively weak. These interfaces are the key points for connecting the host chassis with external devices. Once damaged or interfered, they will directly affect the normal operation of the network system. Especially in data centers, server rooms and other environments, due to dense equipment and complex wiring, power plugs and transmission lines often loosen or fall off, which not only increases maintenance costs, but may also cause more serious system failures. In order to overcome the above problems, a host chassis protection structure based on network system security is proposed, aiming to achieve comprehensive protection of the rear interface of the host chassis through innovative design solutions.

DETAILED DESCRIPTION

[0054] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] Reference Figures 1 to 13 As shown: A host chassis protection structure based on network system security, including a chassis body 1, the rear side of the chassis body 1 is respectively provided with a power socket and a plurality of transmission sockets, the power socket is plugged with a power plug 11, the transmission socket is plugged with a transmission line 12, the rear side of the chassis body 1 is installed with a cover shell 2 capable of wrapping the rear side of the chassis body 1, the cover shell 2 is provided with heat dissipation holes 21, the interior of the cover shell 2 is provided with a first anti-loosening mechanism 3 capable of positioning the transmission line 12, and the interior of the cover shell 2 is also provided with a second anti-loosening mechanism 4 capable of positioning the power plug 11.

[0056] When in use, the cover 2 tightly wraps the back side of the chassis body 1 through locking screws, isolates the power socket, transmission socket, power plug 11 and transmission line 12 from the external environment, and prevents human accidental touch or malicious damage to a certain extent. The first anti-loosening component 3 inside the cover 2 fixes the transmission line 12 in an appropriate position to prevent it from loosening or falling off due to external force, which ensures the stability and reliability of data transmission. The second anti-loosening mechanism 4 fixes the power plug 11 to ensure that the power plug 11 is firmly inserted into the power socket to avoid sudden power outages or power fluctuations caused by unstable power connection. The double protection of the first anti-loosening component 3 and the second anti-loosening mechanism 4 reduces the risk of electrical failure caused by loose connection, thereby protecting the network system from damage.

[0057] Reference Figures 1 to 4 As shown: the first anti-loosening mechanism 3 includes a moving frame 31 and a wire clamp 32;

[0058] The movable frame 31 is vertically arranged inside the housing 2, and an elastic mechanism 5 capable of moving the movable frame 31 toward the rear side of the chassis body 1 is also arranged inside the housing 2;

[0059] A plurality of wire clamps 32 are provided and are evenly spaced and distributed at the upper portion of the moving frame 31 along the vertical direction of the moving frame 31 .

[0060] When the transmission line 12 is inserted into the main box through the transmission socket, the user can guide it to the position of the wire clamp 32 on the mobile frame 31. As the transmission line 12 is inserted, the wire clamp 32 will clamp the transmission line 12. When the transmission line 12 reaches the appropriate position, the wire clamp 32 will firmly clamp the transmission line 12 to prevent it from loosening or falling off. At this time, the elastic mechanism 5 maintains a certain tension so that the mobile frame 31 and the wire clamp 32 are tightly attached to the transmission line 12. There are multiple wire clamps 32. When the number and position of the transmission lines 12 are different, a suitable fixed position can be found. Through the fixing effect of the first anti-loosening mechanism 3, the transmission line 12 can maintain a stable connection state to ensure the reliability and stability of data transmission.

[0061] Reference Figures 4 to 6 As shown: the wire clamp 32 includes an upper clamping plate 321 and a lower clamping plate 322;

[0062] The upper clamping plate 321 is horizontally arranged on the moving frame 31, and a plurality of first clamping grooves are formed on the lower surface of the upper clamping plate 321 and are evenly spaced along the horizontal direction of the upper clamping plate 321;

[0063] The lower clamping plate 322 is arranged directly below the upper clamping plate 321, and the lower clamping plate 322 can move along the vertical direction of the movable frame 31 toward the direction of the upper clamping plate 321. The lower clamping plate 322 is provided with a second clamping groove corresponding to the first clamping groove on each upper clamping plate 321, and the upper clamping plate 321 is provided with a socket 3211 for the lower clamping plate 322 to be inserted. When the lower clamping plate 322 is inserted into the socket 3211 of the upper clamping plate 321, the first clamping groove on the upper clamping plate 321 and the second clamping groove on the lower clamping plate 322 form a first circular closed through-hole for positioning the transmission line 12, and the first limiting sliding blocks 3212 are respectively provided on both sides of the lower clamping plate 322, and the first limiting sliding grooves 3213 for limiting the movement of each first limiting sliding block 3212 are provided on both sides of the inner side of the movable frame 31.

[0064] When no transmission line 12 is inserted into the chassis body 1 , the lower clamping plate 322 is located below the upper clamping plate 321 , and a certain distance is maintained between the two. At this time, the first clamping groove and the second clamping groove are in a separated state. When the transmission line 12 is inserted into the main box through the transmission socket and guided to the position of the wire clamp 32, the user can first place the transmission line 12 in the first clamping groove of the upper clamping plate 321. Then, the user pushes the lower clamping plate 322 upward along the vertical direction of the movable frame 31. Under the guidance of the limiting slider and the limiting sliding groove, the lower clamping plate 322 moves upward smoothly and is inserted into the socket 3211 of the upper clamping plate 321. When the lower clamping plate 322 is fully inserted into the socket 3211 of the upper clamping plate 321, the first clamping groove and the second clamping groove will align with each other and form a complete first circular closed perforation. The first circular closed perforation tightly wraps the transmission line 12 and fixes it by the clamping action of the upper and lower clamping plates 322. Through the clamping action of the wire clamp 32, the transmission line 12 can maintain a stable connection state to prevent it from loosening or falling off due to vibration, pulling, etc. during operation.

[0065] Reference Figure 6 As shown: a first flexible rubber layer 3214 capable of abutting against the outside of the transmission line 12 is adhered in the first clamping groove of the upper clamping plate 321 , and a second flexible rubber layer 3221 capable of abutting against the outside of the transmission line 12 is arranged in the second clamping groove of the lower clamping plate 322 .

[0066] When the lower clamping plate 322 is fully inserted into the socket 3211 of the upper clamping plate 321, the first clamping groove and the second clamping groove are completely aligned, and the two flexible rubber layers together wrap the transmission line 12. At this time, the transmission line 12 is firmly clamped between the upper clamping plate 321 and the lower clamping plate 322. Through this clamping method, the transmission line 12 can not only remain stable in the horizontal and vertical directions, but also avoid damage caused by excessive clamping or vibration.

[0067] Reference Figure 3 , Figure 5 and Figure 7As shown: the second anti-loosening assembly 4 includes an upper slide rail 41, an upper clamping block 42, a lower slide rail 43 and a lower clamping block 44;

[0068] The lower sliding rail 43 is disposed transversely at the inner lower section of the moving frame 31;

[0069] The lower clamping block 44 is disposed above the lower sliding rail 43, and a second limiting slider 441 capable of moving in the horizontal direction along the lower sliding rail 43 is disposed at the bottom of the lower clamping block 44, and a third clamping groove is formed at the top of the lower clamping block 44;

[0070] The upper slide rail 41 is movable toward the lower slide rail 43 and is disposed directly above the lower clamping block 44;

[0071] The upper clamping block 42 is arranged below the upper slide rail 41, and a third limiting sliding block 421 which can move in the horizontal direction along the upper slide rail 41 is arranged on the top of the upper clamping block 42, and a fourth clamping groove which cooperates with the third clamping groove on the lower clamping block 44 is arranged at the bottom of the upper clamping block 42. When the upper clamping block 42 and the lower clamping block 44 are merged, the fourth clamping groove on the upper clamping block 42 and the third clamping groove on the lower clamping block 44 form a second circular closed through-hole for positioning the power plug 11, and vertically arranged limiting columns 442 are arranged on both sides of the top of the lower clamping block 44, and a limiting through-hole 422 for each limiting column 442 to pass through is arranged at the bottom of the upper clamping block 42, and fourth limiting sliding blocks 423 are arranged on both sides of the upper clamping block 42, and a second limiting sliding groove 424 for each second limiting sliding block 441 to limit the movement is arranged on the movable frame 31.

[0072] When the power plug 11 is not inserted, the upper clamping block 42 is located above the upper slide rail 41, and the lower clamping block 44 is located above the lower slide rail 43, and the two maintain a certain distance. When the power plug 11 is inserted into the main box through the power socket, the user moves the upper slide rail 41 downward to an appropriate position so that the upper clamping block 42 can approach the lower clamping block 44. As the upper slide rail 41 continues to descend and the upper clamping block 42 moves horizontally, the upper clamping block 42 gradually approaches the lower clamping block 44. At the same time, the limit column 442 passes through the limit The positioning perforation 422 ensures the alignment accuracy of the two during the merging process. When the upper and lower clamping blocks 44 are completely merged, the fourth clamping groove is aligned with the third clamping groove to form a second circular closed perforation, which firmly fixes the power plug 11 inside. Through the clamping action of the upper clamping block 42 and the lower clamping block 44 and the limiting action of the limiting column 442 and the limiting perforation 422, the power plug 11 is stably fixed in the main chassis to prevent it from loosening or falling off due to vibration, pulling, etc., thereby affecting the damage to the network system.

[0073] Reference Figure 7As shown, a third flexible rubber layer 425 capable of abutting against the outside of the power plug 11 is adhered in the third clamping groove of the upper clamping block 42, and a fourth flexible rubber layer 443 capable of abutting against the outside of the power plug 11 is adhered in the fourth clamping groove of the lower clamping block 44.

[0074] When the upper clamping block 42 is completely merged with the lower clamping block 44, the third clamping groove and the fourth clamping groove are completely aligned, and the third flexible rubber layer 425 and the fourth flexible rubber layer 443 jointly wrap the power plug 11. At this time, the power plug 11 is firmly clamped between the upper clamping block 42 and the lower clamping block 44. Through this clamping method, the power plug 11 can not only remain stable in the horizontal and vertical directions, but also avoid damage caused by excessive clamping or vibration.

[0075] Reference Fig. 9 and Fig.10 As shown: the housing 2 is further provided with a synchronization mechanism 6 capable of simultaneously driving the upper slide rail 41 and each upper clamping plate 321 to move up and down, and the synchronization mechanism 6 includes a first screw 61, a second screw 62 and a moving plate 63;

[0076] The moving plate 63 is arranged at the top center of the moving frame 31, and a rectangular opening is provided on the top of the cover 2 for the moving plate 63 to move horizontally. Fifth limiting sliders 631 are provided on both sides of the moving plate 63, and a third limiting sliding groove 632 is provided inside the rectangular opening of the cover 2 for each fifth limiting slider 631 to limit movement.

[0077] The first screw rod 61 is vertically arranged on a side of the mobile frame 31 away from the chassis body 1. The upper end of the first screw rod 61 is rotatably arranged on the mobile plate 63 and extends upward for a certain distance through the upper and lower surfaces of the mobile plate 63. The lower end of the first screw rod 61 extends to the middle section of the mobile frame 31. The first screw rod 61 is threadedly connected with a first threaded sleeve 64 corresponding to each lower clamping plate 322. The first threaded sleeve 64 is fixedly connected to the side wall of the corresponding lower clamping plate 322. The upper end of the first screw rod 61 is sleeved with a locking nut 611, and the extended end of the first screw rod 61 is also provided with a first knob 612.

[0078] The second screw 62 is coaxially arranged at the lower end of the first screw 61, and one end of the second screw 62 away from the first screw 61 extends toward the lower side of the movable frame 31. A bearing sleeve 65 for rotating the second screw 62 is provided on the lower side wall of the movable frame 31. The threads of the second screw 62 and the first screw 61 are arranged in opposite directions. A second threaded sleeve 66 is threadedly connected to the second screw 62, and the second threaded sleeve 66 is fixedly connected to the side wall of the upper slide rail 41.

[0079] When it is necessary to adjust the first anti-loosening mechanism 3 and the second anti-loosening mechanism 4, the user drives the first screw 61 to rotate by rotating the first knob 612. Since the first screw 61 is threadedly connected to the first threaded sleeve 64 of each lower clamping plate 322, and the rotation direction of the first screw 61 is the same, all lower clamping plates 322 will rise and fall synchronously. At the same time, since the second screw 62 is coaxial with the first screw 61 and the threads are set in opposite directions, when the first screw 61 rotates, the second screw 62 will rotate in the opposite direction. Since the second screw 62 is threadedly connected to the second threaded sleeve 66 of the upper slide rail 41, the upper slide rail 41 will also rise and fall synchronously, but its moving direction is opposite to that of the lower clamping plate 322. After adjusting to the desired position, the user can tighten the locking nut 611 to lock the position of the first screw 61 to prevent it from accidentally rotating and causing movement of the upper and lower clamping plates 322.

[0080] Reference Figure 5 and Figure 8 As shown: the elastic mechanism 5 includes a polished rod 51 and a spring 52;

[0081] A rectangular cavity 53 is provided at each corner of the housing 2. The number of the polished rods 51 is the same as the number of the rectangular cavities 53 and is arranged in the rectangular cavities 53 in a one-to-one correspondence. The polished rods 51 are arranged horizontally. A first linear bearing 54 capable of moving along the axial direction of each polished rod 51 is provided at each corner of the movable frame 31.

[0082] The number of springs 52 is the same as the number of light rods 51 and they are arranged on the light rods 51 in a one-to-one manner. One end of the spring 52 is abutted against the side of the first linear bearing 54 away from the main body. A pre-tightening mechanism is also provided inside the cover 2, which can compress each spring 52 toward the corresponding first linear bearing 54.

[0083] When the first anti-loosening mechanism 3 and the second anti-loosening mechanism 4 position the corresponding transmission line 12 and the power plug 11, under the action of the pre-tightening mechanism, each spring 52 is compressed to a certain extent, and the spring 52 will then undergo elastic deformation and generate elastic force to support and buffer the movement of the movable frame 31, so that the positioned transmission line 12 and the power plug 11 can be positioned more stably.

[0084] Reference Figure 3 and Figures 11 to 13 As shown, the pre-tightening mechanism includes a pre-tightening frame 551 , an outer sleeve 552 , an inner sleeve 553 , an inner rod 554 and a second knob 555 .

A second linear bearing 556 capable of moving along the axial direction of each light rod 51 is arranged at each corner of the pre-tightening frame 551. One side of the second linear bearing 556 is arranged in contact with an end of the spring 52 away from the first linear bearing 54.

[0086] The outer sleeve 552 is horizontal and passes through the rear center of the housing 2 and is fixedly arranged;

[0087] The inner sleeve 553 is arranged inside the outer sleeve 552. The outer surface of the inner sleeve 553 is provided with an external thread. The inner wall of the outer sleeve 552 is provided with an internal thread connected with the external thread. One end of the inner sleeve 553 passes through one end of the outer sleeve 552 and is rotatably connected with the side wall of the pre-tightening frame 551.

[0088] The inner rod 554 is arranged inside the inner sleeve 553, and a strip-shaped stopper 5541 extending along the axis direction of the inner rod 554 is arranged outside the inner rod 554. A strip-shaped stopper groove 5542 is arranged on the inner wall of the inner sleeve 553 for the strip-shaped stopper 5541 to move horizontally along its axis. One end of the inner rod 554 can rotate through the outer sleeve 552 and extend outwardly away from the end of the housing 2.

[0089] The second knob 555 is disposed at the extended end of the inner rod 554 .

[0090] In the initial state, the preload mechanism sets the preload force of the spring 52 by adjusting the position of the inner sleeve 553 in the outer sleeve 552. When the preload frame 551 is adjusted, the inner rod 554 is driven to rotate by rotating the second knob 555. Since the cooperation between the strip-shaped limit block 5541 and the strip-shaped limit groove 5542 limits the rotational movement of the inner rod 554, the inner rod 554 will drive the inner sleeve 553 to move axially in the outer sleeve 552, and further drive the preload frame 551 and the second linear bearing 556 to move along the direction of the light rod 51, thereby changing the compression degree of the spring 52 and adjusting the preload force. When the required preload force is adjusted, the user can lock the inner sleeve 553 by means of a locking nut, etc. The locking nut does not belong to the protection scope of this application, so the position of locking the inner sleeve 553 is not shown in the figure to prevent it from accidental movement and maintain the stability of the preload force. Through the coordinated action of the outer sleeve 552, the inner sleeve 553, the inner rod 554 and the second knob 555, the precise adjustment of the preload force of the spring 52 is achieved.

[0091] Reference Figure 2 As shown, a first threading opening 23 corresponding to each upper clamping plate 321 is opened on the rear side wall of the cover shell 2, and a second threading opening 24 corresponding to the lower clamping block 44 is also opened on the rear side wall of the cover shell 2.

[0092] The first threading opening 23 provides a passage for the transmission line 12 that needs to pass through the housing 2 and be connected to the upper clamping plate 321 , and the second threading opening 24 provides a passage for the power socket that passes through the housing 2 and is connected to the lower clamping block 44 .

[0093] The present invention also provides a mainframe box, which is applied to a mainframe box protection structure based on network system security.
