[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0032] As described in the background art, there is a gap between the inner wall of the cabinet and the corresponding structural parts installed inside the cabinet, which may cause the problem of hot air backflow inside the cabinet. When server equipment is installed inside the cabinet, since the server equipment has high requirements for the air flow conditions inside the cabinet, the above-mentioned hot air backflow problem may have an adverse effect on the normal operation of the server equipment.

[0033] After disassembling and studying the current cabinets, the researchers of the utility model found that the root cause of the hot air reflux problem inside the cabinet is the air leakage area formed by the gap between the square hole bar and the cabinet front door column. Among them, the square hole bar is a metal bar installed inside the cabinet in the vertical direction, usually located on the front and back sides of the cabinet. There are multiple square holes arranged at intervals along the height direction on the square hole bar. These square holes are used to install the pallet and the cabinet blind plate. The pallet is a plate-shaped support structure for installing servers, switches, routers and other equipment, and the cabinet blind plate is used to seal the empty U position in the cabinet to play the role of sealing the U position.

[0034] In order to solve the problem of hot air reflux, some cabinets are equipped with side panel structures, which are used to block the gap between the square hole bar and the cabinet front door column. However, the addition of the side panel structure will lead to additional consumption of cabinet panels, and it is necessary to make additional holes in the cabinet to fix the side panel structure, which will increase material costs and installation costs. On the other hand, when there is no server equipment installed in the cabinet, there is no need to solve the problem of hot air reflux inside the cabinet, that is, at this time, the gap between the square hole bar and the cabinet front door column does not need to be blocked, but the side panel structure is not easy to disassemble after installation. In other words, the side panel structure is a redundant structure for cabinets without server equipment installed.

[0035] Based on the above problems and findings, the utility model proposes a cabinet blind plate structure, in which a movable splint is arranged on the cabinet blind plate. Through the cooperation between the splint and the seal, the gap causing the hot air reflux problem can be sealed when the server equipment is installed in the cabinet, and the gap can be flexibly switched to a state where the gap is not sealed when the server equipment is not installed in the cabinet.

[0036] See also Figures 1 to 3 In one embodiment of the utility model, the cabinet blind plate structure includes a blind plate body 1, a clamping plate 2 and a sealing member 3; the blind plate body 1 is installed on the square hole bar 51 of the cabinet body 5 and occupies the empty U position of the cabinet body 5, and there is a preset gap between the square hole bar 51 and the front door column 52 of the cabinet body 5; the clamping plate 2 is slidably connected to the blind plate body 1; the sealing member 3 is movably arranged in the cabinet body 5.

[0037] When a server device is arranged in the cabinet body 5, the clamping plate 2 is used to slide to a first position relative to the blind plate body 1 and abut against the sealing member 3 so as to press and fix the sealing member 3 in a preset gap.

[0038] In this embodiment, the cabinet body 5 is a cabinet structure formed by connecting a plurality of sheet metal parts, and a storage space for installing structural parts and various equipment is formed inside the cabinet body 5. The square hole bars 51 are arranged along the vertical direction and are located at the front and rear sides of the cabinet body 5; wherein, the preset gap between the front square hole bars 51 and the front door column 52 of the cabinet body 5 forms an air leakage area, which may cause a hot air backflow problem inside the cabinet.

[0039] The blind plate body 1 can be locked and fixed in the square hole at a preset height on the square hole bar 51, so that the blind plate body 1 occupies the empty U position of the cabinet body 5 and plays the role of sealing the U position. The clamping plate 2 can be slidably connected to the blind plate body 1 through the cooperation of the guide rail slider and the like, which is not limited here; in an exemplary embodiment, a waist-shaped hole can be opened on the blind plate body 1, and the extension path of the waist-shaped hole should be consistent with the preset sliding path of the clamping plate 2, and a guide rod structure penetrating in the waist-shaped hole is provided on the clamping plate 2. The guide rod structure can be a threaded locking piece such as a screw or a bolt locked on the clamping plate 2. When the clamping plate 2 slides into place relative to the blind plate body 1 along the preset sliding path under the cooperation of the threaded locking piece and the waist-shaped hole, the threaded locking piece can be locked to fix the clamping plate 2 on the blind plate body 1.

[0040] The seal 3 can be any hard or flexible structural part with a sealing effect; a corresponding limiting structure can be set inside the cabinet body 5 so that the seal 3 can be movably connected to the inside of the cabinet body 5 through the limiting structure; specifically, the limiting structure can be a groove-like structure extending in the horizontal direction, which can support the seal 3 in the vertical direction and allow the seal 3 to move along a preset trajectory in the horizontal direction.

[0041] Based on the above configuration, when no server equipment is installed in the cabinet body 5, there is no need to seal the preset gap between the square hole strip 51 and the front door column 52 of the cabinet body 5. At this time, the blind plate body 1 can be used as an ordinary blind plate, and the plywood 2 can be used as Figure 2 As shown in the figure, the blind plate body 1 slides in the direction away from the preset gap to the coverage range without blocking the preset gap, and the seal 3 can also be moved to a position where it does not block the preset gap. When a server device is installed in the cabinet body 5, it is necessary to seal the preset gap between the hole strip 51 and the front door column 52 of the cabinet body 5. At this time, the seal 3 can be moved to the preset gap, and the clamp 2 can be moved as shown in the figure. Figure 1 As shown, it slides outside the coverage of the blind plate body 1; when the splint 2 slides to the first position, the splint 2 will abut against the seal 3. At this time, the splint 2 can press and fix the seal 3 in the preset gap, so that a stable sealing effect can be formed on the air leakage area through the seal 3, solving the problem of hot air reflux inside the cabinet body 5, optimizing the air flow organization inside the cabinet body 5, and thus ensuring the stable operation of server equipment with high requirements on air flow conditions.

[0042] It can be seen that the blind plate body 1 of the present embodiment is equipped with a slidable clamping plate 2. When no server equipment is installed in the cabinet body 5 and there is no need to seal the preset gap between the square hole strip 51 and the front door column 52, the clamping plate 2 can slide to a position where it does not block the preset gap, and the blind plate body 1 can be used as an ordinary blind plate; when server equipment is installed in the cabinet body 5, the clamping plate 2 can be slid to the first position and abut against the seal 3 to press the seal 3 into the preset gap, so that the seal 3 can form a stable sealing effect on the air leakage area. The above scheme realizes the sealing of the air leakage area inside the cabinet body 5 in a convenient and easy-to-operate manner, solves the problem of hot air reflux inside the cabinet body 5, and optimizes the airflow organization inside the cabinet body 5, thereby ensuring the stable operation of server equipment with high requirements for airflow conditions, and can flexibly switch between the sealed and non-sealed states as needed, which can better meet the use requirements of the cabinet; in addition, the function of the blind plate body 1 is also expanded, so that the blind plate body 1 is not limited to the role of a single sealing U position, and there is no need to add a complex side panel structure inside the cabinet body 5, thereby reducing material costs and installation costs.

[0043] Optionally, refer to Figures 1 to 3 The blind plate body 1 is provided with a guide rail structure 4, and the clamping plate 2 is slidably connected to the guide rail structure 4 in the direction of approaching or moving away from the sealing member 3. Through the limiting effect of the guide rail structure 4, the clamping plate 2 can be stably moved along a preset track, ensuring that the clamping plate 2 can move into position relative to the blind plate body 1, and preventing the clamping plate 2 from being separated from the blind plate body 1.

[0044] Optionally, refer to Figures 1 to 3 The guide rail structure 4 includes a telescopic slide rail (not shown in the figure), the fixed part of the telescopic slide rail is installed on the blind plate body 1, and the clamping plate 2 is connected to the movable part of the telescopic slide rail.

[0045] Specifically, the track portion of the telescopic slide rail is a multi-section structure. The fixed portion of the telescopic slide rail can refer to the track segment fixed to the blind plate body 1, and the movable portion of the telescopic slide rail can refer to the remaining track segments that can telescopically slide relative to the fixed portion. When the splint 2 moves in a direction close to the seal 3, the movable portion of the telescopic slide rail extends outward relative to the fixed portion; when the splint 2 moves in a direction away from the seal 3, the movable portion of the telescopic slide rail contracts inward relative to the fixed portion. By setting up a telescopic slide rail, there is no need to seal the air leakage area, and the splint 2 can be Figure 2 When the guide rail structure 4 slides into the coverage of the blind plate body 1 as shown, the guide rail structure 4 can be stored together in the coverage of the blind plate body 1 to avoid the guide rail structure 4 still occupying the space in the air leakage area and easily interfering with other devices.

[0046] Optionally, refer to Figures 1 to 3The guide rail structure 4 is provided with a tightening mechanism (not shown in the figure); the tightening mechanism is used to abut against the clamping plate 2 when the clamping plate 2 slides to the first position to prevent the clamping plate 2 from continuing to slide.

[0047] By setting up a tightening mechanism, the clamping plate 2 moved into position can be fixed so that the clamping plate 2 always maintains a stable abutment with the seal 3, thereby preventing the clamping plate 2 from retreating relative to the blind plate body 1 under external influences such as vibration, causing the seal 3 to be unable to be firmly pressed in the sealing position, thereby improving the sealing stability and reliability.

[0048] Among them, the tightening mechanism can be in the form of a set screw, a buckle, a pressure block, etc., and it is only necessary to ensure that when the splint 2 slides to the first position, the operator can fix the splint 2 on the blind plate body 1 through the tightening mechanism; taking the set screw as an example, when the splint 2 slides to the first position, the operator can screw the set screw to make one end of the set screw press against the splint 2, and the pressing direction of the set screw can be perpendicular to the sliding direction of the splint 2, so as to prevent the splint 2 from continuing to slide through the pressing force; taking the buckle as an example, when the splint 2 slides to the first position, the operator can buckle the movable part of the buckle into the corresponding matching structure of the splint 2, so as to prevent the splint 2 from continuing to slide through the matching between the buckle and the splint 2. When the tightening mechanism adopts other forms, its fixing principle and effect can be derived in the same way, which will not be repeated here.

[0049] Optionally, refer to Figures 1 to 3 The tightening mechanism includes a spring plunger (not shown in the figure), which is locked to the guide rail structure 4; the clamping plate 2 is provided with a positioning cavity (not shown in the figure); when the clamping plate 2 slides to the first position, the plunger portion of the spring plunger is used to abut and fit in the positioning cavity.

[0050] In this embodiment, when the splint 2 slides to the first position, the plunger portion of the spring plunger is opposite to the positioning cavity of the splint 2. At this time, the plunger portion of the spring plunger will extend out under the elastic action and abut against the positioning cavity, thereby realizing the self-locking of the splint 2, and the splint 2 can be automatically fixed after sliding into place without the need for additional manual operation of the tightening mechanism; if it is necessary to switch to the non-sealed state later, it is only necessary to apply a certain external force to the splint 2 in the direction away from the sealing member 3, so that the plunger portion overcomes the elastic force of the spring plunger under the action of the external force and disengages from the positioning cavity, so that the splint 2 can continue to slide relative to the blind plate body 1 to the position as shown in the figure. Figure 2 Storage position shown.

[0051] Optionally, refer to Figures 1 to 3The clamping plate 2 is provided with a serrated structure (not shown in the figure), and the serrated structure is used to fit with the seal 3. By providing the serrated structure, the friction between the clamping plate 2 and the seal 3 can be increased, thereby improving the pressing stability of the clamping plate 2 on the seal 3, thereby better ensuring the sealing effect.

[0052] Optionally, refer to Figures 1 to 3 The clamping plate 2 has a contact surface (not shown in the figure), which is inclined upward in a direction close to the sealing member 3, and is used to contact the sealing member 3 when the clamping plate 2 slides to the first position.

[0053] Specifically, when the clamp 2 slides to the first position, since the clamp 2 is located away from the blind plate body 1, under the action of gravity, the clamp 2 tends to move downward relative to the blind plate body 1; and based on the inclination direction of the abutment surface, when the clamp 2 tends to move downward, the abutment surface can produce an oblique downward pressing force on the seal 3, and the horizontal component of the pressing force will further press the seal 3 against the cabinet body 5 in the horizontal direction. In this way, the downward movement trend of the clamp 2 can be cleverly utilized to further enhance the tightness of the clamp 2 on the seal 3, thereby further improving the sealing stability and reliability.

[0054] Optionally, refer to Figures 1 to 3 The seal 3 is made of flame-retardant hard material, which can reduce the probability of spontaneous combustion of the seal 3 under high temperature conditions and eliminate safety hazards. Preferably, the seal 3 is made of phenolic laminated paperboard, which has excellent properties such as insulation, no static electricity, wear resistance, and high temperature resistance, which can extend the service life of the seal 3 and ensure the stability of the internal environment of the cabinet body 5.

[0055] See also Figures 1 to 3 The utility model also proposes a cabinet assembly, including a cabinet body 5 and a cabinet blind plate structure in any of the above embodiments; the blind plate body 1 of the cabinet blind plate structure is installed on the square hole bar 51 of the cabinet body 5 and occupies the empty U position of the cabinet body 5, and there is a preset gap between the square hole bar 51 and the front door column 52 of the cabinet body 5.

[0056] When the server equipment is installed in the cabinet body 5, the clamping plate 2 of the cabinet blind plate structure slides to the first position relative to the blind plate body 1 and abuts against the sealing member 3 to press and fix the sealing member 3 in the preset gap.

[0057] For the specific structure of the cabinet blind plate structure, reference can be made to the above embodiments. Since the cabinet assembly in this embodiment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, that is, the blind plate body 1 is provided with a slidable clamping plate 2. When the server equipment is not installed in the cabinet body 5 and there is no need to seal the preset gap between the square hole bar 51 and the front door column 52, the clamping plate 2 can slide to a position where it does not block the preset gap, and the blind plate body 1 can be used as an ordinary blind plate; when the server equipment is installed in the cabinet body 5, the clamping plate 2 can be slid to the first position and abut against the seal 3 to press and fix the seal 3 in the preset gap, so that the seal 3 can form a stable sealing effect on the air leakage area. The above scheme realizes the sealing of the air leakage area inside the cabinet body 5 in a convenient and easy-to-operate manner, solves the problem of hot air reflux inside the cabinet body 5, and optimizes the airflow organization inside the cabinet body 5, thereby ensuring the stable operation of server equipment with high requirements for airflow conditions, and can flexibly switch between the sealed and non-sealed states as needed, which can better meet the use requirements of the cabinet; in addition, the function of the blind plate body 1 is also expanded, so that the blind plate body 1 is not limited to the role of a single sealing U position, and there is no need to add a complex side panel structure inside the cabinet body 5, thereby reducing material costs and installation costs.

[0058] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
