[0042] Industrial servers are a type of industrial computer widely used in IT communications, industrial automation, security monitoring, vehicle inspection, and other industries. With the increasing demand for big data and computing power, the demand for industrial servers has gradually expanded to various industries, including those in dusty environments such as coal, mining, food, and chemicals, as well as those in high-radiation and high-electromagnetic compatibility environments such as nuclear power plants, substations, and power stations.

[0043] However, the face shields of traditional industrial servers can usually only prevent the hard disk from being removed by non-staff, and do not have the ability to work normally in dusty application environments, thus failing to meet the requirements for the normal operation of industrial servers in dusty environments.

[0044] Based on this, the present application provides a server mask, which includes a mask body, a connecting assembly and a switch assembly. A rotatable shaft is set in the mask body, and the fan blades fixed on the shaft are driven to rotate by toggling the switch assembly, so that when the mask body is covered on the side of the server chassis with an opening through the connecting assembly, the opening is closed or opened by the fan blades, so that the opening can be opened in an environment with low dust prevention requirements for the server, thereby improving the heat dissipation effect of the server, and the opening can be closed in a dusty environment, effectively preventing dust from entering the inside of the server chassis, ensuring the operation of the server, so that the server can work normally and stably in environments with various degrees of dust pollution.

[0045] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram showing the structure of the server provided in the embodiment of the present application is shown. Figure 2 The following is a schematic diagram showing the structure of the server mask provided in an embodiment of the present application. Figure 3 The server mask and connecting assembly provided in an embodiment of the present application are shown in a schematic structural diagram. As shown in the figure, the server mask 10 is applied to a chassis 20, and an opening 21 is provided on one side of the chassis 20. The server mask 10 includes a mask body 100, a connecting assembly 200 and a switch assembly 300. The mask body 100 is detachably connected to the side of the chassis 20 where the opening 21 is located through the connecting assembly 200 and covers the opening 21. The mask body 100 includes an outer frame 110 and a plurality of rotating shafts 120 passing through both ends of the outer frame 110. The outer frame 110 is fixedly connected to the connecting assembly 200. Each rotating shaft 120 is rotatably connected to the outer frame 110, and one end of each rotating shaft 120 after passing through the outer frame 110 is transmission-connected to the switch assembly 300. The portion of each rotating shaft 120 located inside the outer frame 110 is fixedly provided with a fan blade 400. The switch assembly 300 is used to drive the rotating shaft 120 to rotate when it is toggled, so that the fan blade 400 closes or opens the opening 21.

[0046] like Figure 2 As shown, server 1 includes a server mask 10 and a chassis 20. Server 1 may be an industrial server, with multiple hard drives, motherboards, and other electronic components installed within chassis 20. An opening 21 is provided on one side of chassis 20, and multiple hard drives are installed near opening 21. This allows heat generated by all hard drives to dissipate quickly through opening 21 to the outside environment. To prevent the hard drives or electronic components within chassis 20 from being removed, a server mask 10 is provided on the side of chassis 20 where opening 21 is located, so that the server mask 10 covers opening 21 and protects the components within chassis 20.

[0047] The two ends of the mask body 100 are respectively fixedly connected to the connecting components 200, for example, they can be adhesively fixed, welded or detachably fixed, and the connecting components 200 are respectively detachably connected to the side walls of the chassis 20, such as snap-on or threaded connections, so that the server mask 10 can be detachably connected to the side of the opening 21 of the chassis 20 and cover the opening 21.

[0048] The outer frame 110 is made of a lightweight, heat-resistant engineering plastic alloy, the rotating shaft 120 is made of a metal material, such as stainless steel, and the fan blades 400 are made of a conductive material and are made by a blow molding process, such as Figure 4 As shown, the fan blade 400 is provided with a plurality of tiny air holes, which can effectively prevent dust from passing through.

[0049] Specifically, both ends of the outer frame 110 can be fixed to the connecting assembly 200 by bonding, welding, or detachable fixing. A plurality of through holes can be provided at equal intervals at both ends of the outer frame 110, and each rotating shaft 120 can be rotatably mounted on the outer frame 110 by sequentially passing through the through holes at both ends of the outer frame 110.

[0050] like Figure 4 As shown, a crossbeam 410 can be provided at the center of the fan blade 400 so as to fix the fan blade 400 on each rotating shaft 120 through the crossbeam 410. For example, a pin hole or a threaded hole can be provided at both ends of each rotating shaft 120, and a pin groove or a threaded groove can be provided at the corresponding position of the crossbeam 410 and the pin hole or threaded hole on the back of each fan blade 400. A pin can be knocked into the interior of the rotating shaft 120 and the fan blade 400, or a screw can be screwed into the interior of the rotating shaft 120 and the fan blade 400. The pin or screw can play a role in positioning and limiting, and fix the fan blade 400 on the rotating shaft 120. In the embodiment of the present application, the length of the fan blade 400 is equal to the length of the portion of the rotating shaft 120 located inside the outer frame 110, so that the fan blade 400 can completely close the opening 21 when the server mask 10 is covered on the chassis 20.

[0051] Preferably, the switch assembly 300 can be fixedly mounted on the connecting assembly 200. The switch assembly 300 can be toggled, for example, upward or downward. The switch assembly 300 is in driving connection with one end of each rotating shaft 120 that passes through the outer frame 110. That is, when the switch assembly 300 is toggled, each rotating shaft 120 can be driven to rotate simultaneously.

[0052] For example, when the switch assembly 300 is toggled upward, each rotating shaft 120 connected to the switch assembly 300 rotates clockwise, thereby driving the fan blades 400 fixed thereto to rotate clockwise. As a result, each fan blade 400 rotates to a position perpendicular to the outer frame 110, and the opening 21 is opened. When the opening 21 is open, it facilitates the entry of external airflow into the chassis 20. Without increasing the speed of the fan inside the server 1, sufficient airflow can be ensured to enter the chassis 20, thereby reducing the power consumption of the server 1 and saving electricity.

[0053] When the switch assembly 300 is toggled downward, each rotating shaft 120 connected to the switch assembly 300 rotates counterclockwise, thereby driving the fan blades 400 fixed thereon to rotate counterclockwise, so that each fan blade 400 rotates to a state parallel to the outer frame 110, and the opening 21 is closed by the fan blades 400. When the opening 21 is in the closed state, the external airflow must be filtered through the holes on the fan blades 400 before it can enter the interior of the chassis 20, effectively filtering out large particles of dust and ensuring the normal operation of the server 1. In this state, the operating speed of the fan inside the server 1 needs to be increased to ensure sufficient airflow inside the chassis 20 so that the server 1 can dissipate heat normally.

[0054] In the server mask 10 provided in the embodiment of the present application, the mask body 100 is detachably connected to the side of the opening 21 of the chassis 20 through the connecting component 200 and covers the opening 21, so that the server mask 10 can protect the internal components of the server 1; the mask body 100 includes an outer frame 110 fixedly connected to the connecting component 200 at both ends and a plurality of rotating shafts 120 passing through the two ends of the outer frame 110, the plurality of rotating shafts 120 are rotatably connected to the outer frame 110, and one end of each rotating shaft 120 is transmission-connected to the switch component 300, so that the server mask 10 can protect the internal components of the server 1; When 300 is turned, it can drive each rotating shaft 120 to rotate, and then drive the fan blades 400 fixed on each rotating shaft 120 in the outer frame 110 to rotate, so that the fan blades 400 close or open the opening 21, thereby being able to open the opening 21 in an environment with low dustproof requirements for the server, thereby improving the heat dissipation effect of the server 1, and being able to close the opening 21 in a dusty environment, effectively preventing dust from entering the interior of the server 1 chassis, ensuring the operation of the server 1, so that the server 1 can work normally and stably in environments with various degrees of dust pollution.

[0055] In order to shield electromagnetic interference, this application further proposes an implementation method, please continue to refer to Figure 1 As shown in the figure, the surfaces of the mask body 100, the connecting assembly 200 and the switch assembly 300 are coated with conductive materials, and the fan blades 400 are made of metal materials.

[0056] Specifically, conductive paint can be sprayed on the surfaces of the mask body 100, the connecting assembly 200 and the switch assembly 300, and the fan blades 400 can be made of carbon-based materials and PVC (polyvinyl chloride) materials.

[0057] Since the mask body 100, the connecting assembly 200, the switch assembly 300 and the fan blades 400 are all conductive, that is, the entire server mask 10 is conductive and connected, and there is no open gap when the fan blades 400 close the opening 21. Therefore, the entire server 1 can effectively shield electromagnetic interference when the fan blades 400 close the opening 21. Since electromagnetic waves and radiation sources cannot enter the interior of the chassis 20, they will not cause signal interference to the hard disk and motherboard inside the chassis 20, thereby ensuring the stability of the normal operation of the server 1. In addition, the electromagnetic waves inside the chassis 20 will also be shielded within the chassis 20 and will not cause electromagnetic interference to other electronic devices in the outside world.

[0058] In order to reduce the risk of deformation of the shaft 120, this application further proposes an implementation method, please continue to refer to Figure 1 and Figure 3 , and combined with Figure 5 , Figure 5 An exploded view of the mask body provided in an embodiment of the present application is shown. As shown in the figure, the outer frame 110 includes a frame 111 and a plurality of support rods 112. The frame 111 is fixedly connected to the connecting assembly 200. Each support rod 112 is arranged perpendicular to the rotating shaft 120, and the two ends of each support rod 112 are respectively fixedly connected to the inner wall of the frame 111 to separate the frame 111 into a plurality of windows 113. Each rotating shaft 120 passes through the frame 111 and each support rod 112, and is rotatably connected to the frame 111 and each support rod 112. The portion of each rotating shaft 120 located in each window 113 is respectively fixedly provided with a fan blade 400.

[0059] Optionally, the two ends of each support rod 112 can be connected and fixed to the inner wall of the frame 111 by bonding, welding or detachable connection, so that each support rod 112 can be installed and fixed in the frame 111 at equal intervals, thereby dividing the frame 111 into multiple windows 113 of the same size.

[0060] A plurality of through holes can be opened at equal intervals on the frame 111 and the plurality of support rods 112 , and each rotating shaft 120 can be passed through the through holes of the frame 111 and the plurality of support rods 112 so that each rotating shaft can be rotatably installed on the frame 111 and the plurality of support rods 112 .

[0061] Due to the separating function of the support rod 112, each rotating shaft 120 is divided into multiple parts located in each window 113. Therefore, a fan blade 400 can be configured for the part of the rotating shaft 120 located in each window 113, and the length of each fan blade 400 is set to the length of the part of the rotating shaft 120 located in each window 113, so that the fan blade 400 can close or open each window 113.

[0062] In this case, multiple support rods 112 and the frame 111 jointly support each rotating shaft 120 and the fan blades 400 fixed thereon, which can reduce the deformation risk of the rotating shaft 120 and thus ensure the sealing of the opening 21 by the fan blades 400.

[0063] In order to control the rotation of the shaft 120 and thus control the fan blade 400 to close or open the opening 21, the present application further proposes an implementation method, please continue to refer to Figure 5 , and combined with Figure 6 , Figure 6 An exploded view of a switch assembly provided in an embodiment of the present application is shown. As shown in the figure, the switch assembly 300 includes a belt 310 and a plurality of pulleys 320. The plurality of pulleys 320 are sleeved one-to-one on one end of the rotating shaft 120. The belt 310 is sleeved on all the pulleys 320, so that all the pulleys 320 are connected through the belt 310. A slide hole 201 is formed on the connecting assembly 200. The switch assembly 300 also includes a shift block 330. The shift block 330 passes through the slide hole 201 and is fixedly connected to the belt 310. When the shift block 330 is shifted, it is used to drive all the pulleys 320 to rotate through the belt 310, thereby driving each rotating shaft 120 to rotate.

[0064] Among them, the belt 310 can be a belt with teeth on the inner surface, and teeth that match the teeth on the inner surface of the belt 310 can be provided on the surface of the pulley 320. After the belt 310 is sleeved on all the pulleys 320, all the pulleys 320 can be driven to rotate simultaneously by rotating the belt 310.

[0065] The number of pulleys 320 is the same as the number of rotating shafts 120, and the multiple pulleys 320 are sleeved on the multiple rotating shafts 120 in a one-to-one correspondence. Specifically, threaded holes can be opened in the pulleys 320, and threads can be provided on one end surface of the rotating shaft 120. By screwing one end of the rotating shaft 120 into the threaded holes of the pulleys 320, each pulley 320 is sleeved on one end of each rotating shaft 120.

[0066] like Figure 6As shown, the switch block 330 may include a blade switch 331 and a switch clip 332. A paddle that can be moved upward or downward is provided on one side of the blade switch 331, and a groove may be provided on the other side of the blade switch 331. One end of the switch clip 332 is welded to the outer surface of the belt 310, and the other end passes through the slide hole 201 and is inserted into the groove of the blade switch 331. This allows the switch clip 332 to slide within the slide hole 201 as the paddle is moved, thereby driving the belt 310 to rotate.

[0067] For example, when the paddle of the fan blade switch 331 is toggled upward, the switch buckle 332 slides upward to one end of the slideway hole 201, driving the belt 310 to rotate clockwise, which in turn drives all the pulleys 320 to rotate clockwise, causing all the rotating shafts 120 to rotate clockwise, thereby causing the fan blade 400 to open the opening 21. When the paddle of the fan blade switch 331 is toggled downward, the switch buckle 332 slides downward to the other end of the slideway hole 201, driving the belt 310 to rotate counterclockwise, which in turn drives all the pulleys 320 to rotate counterclockwise, causing all the rotating shafts 120 to rotate counterclockwise, thereby causing the fan blade 400 to close the opening 21.

[0068] In order to quickly install and fix the mask body 100 on the side of the chassis 20 where the opening 21 is opened, the present application further proposes an implementation method, please continue to refer to Figure 1 and Figure 2 , and combined with Figure 7-11 , Figure 7 and Figure 8 Exploded views of the first connecting member and the second connecting member provided in the embodiments of the present application are shown respectively. Figure 9 and Figure 10 sectional views of the first connecting member and the second connecting member provided in the embodiment of the present application are shown respectively. Figure 11 Shown Figure 2A partial enlarged view of the connection assembly 200 is shown. As shown in the figure, the connection assembly 200 includes a first hanging ear 210, a second hanging ear 220, a first connecting member 230, and a second connecting member 240. The first hanging ear 210 and the second hanging ear 220 are detachably connected to the side of the opening 21 on the chassis 20, and the first hanging ear 210 and the second hanging ear 220 are respectively located at both ends of the opening 21. Lock tongue holes 202 are provided on the two sides facing each other between the first hanging ear 210 and the second hanging ear 220. The first connecting member 230 and the second connecting member 240 are respectively fixed to the two ends of the outer frame 110, and the first connecting member 230 and the second connecting member 240 are both provided with an elastically retractable locking tongue 250 on the side facing away from the outer frame 110. The two locking tongues 250 are used to be elastically retracted by being squeezed by the surfaces of the first hanging ear 210 and the second hanging ear 220 when the mask body 100, the first connecting member 230 and the second connecting member 240 move toward the opening 21 together. When the mask body 100, the first connecting member 230 and the second connecting member 240 move to the locked position, the two locking tongues 250 pop out and engage with the locking tongue holes 202 on both sides to connect and fix the first connecting member 230 to the first hanging ear 210, and to connect and fix the second connecting member 240 to the second hanging ear 220.

[0069] The first hanging ear 210 and the second hanging ear 220 can be respectively snap-fitted or threadedly connected to the side walls of the chassis 20 to be fixed at both ends of the opening 21 .

[0070] Specifically, the two ends of the outer frame 110 can be respectively fixed to the first connecting member 230 and the second connecting member 240 by adhesive bonding, welding, or detachable fixing. In the embodiment of the present application, a plurality of threaded holes can be provided on both ends of the outer frame 110, and threaded holes can be provided at positions corresponding to each threaded hole on the first connecting member 230 and the second connecting member 240. By screwing screws into the threaded holes of the outer frame 110, the first connecting member 230, and the second connecting member 240, the outer frame 110 can be respectively connected and fixed to the first connecting member 230 and the second connecting member 240.

[0071] The lock tongue 250 can be made of an elastic material, enabling elastic expansion and contraction, or it can be made of a non-elastic material, such as carbon steel, achieving elastic expansion and contraction by moving horizontally. For example, the two lock tongues 250 can be slidably connected to the first connector 230 and the second connector 240, respectively, so that the two lock tongues 250 can slide away from or toward each other on the side of the first connector 230 and the second connector 240 facing away from the outer frame 110. In the embodiments of the present application, the specific structure and shape of the lock tongue 250 are not specifically limited.

[0072] Optionally, elongated protrusions may be provided on both sides facing each other between the first hanging ear 210 and the second hanging ear 220, and grooves adapted to the elongated protrusions may be further provided on both sides facing each other between the first connecting member 230 and the second connecting member 240, so that the locking tongue 250 is aligned with the locking tongue hole 202 through the mutual cooperation of the protrusions and the grooves, and the mask body 100, the first connecting member 230, and the second connecting member 240 are quickly and smoothly pushed toward the opening 21 of the chassis 20. Furthermore, by extending the grooves to the edges of the first connecting member 230 and the second connecting member 240, and setting the width of the cross section of the grooves at the edges to be greater than the width of the cross section at other locations, the protrusions can be slid into the grooves more quickly to guide the movement of the mask body 100, the first connecting member 230, and the second connecting member 240 toward the opening 21.

[0073] In this case, when the protrusion completely slides into the groove, the mask body 100, the first connecting member 230 and the second connecting member 240 move to the locked position.

[0074] When the mask body 100, the first connecting member 230, and the second connecting member 240 move together toward the opening 21, the two locking tongues 250 are respectively squeezed by the surfaces of the first hanging ear 210 and the second hanging ear 220 and slide away from each other, i.e., elastically retract, allowing the mask body 100, the first connecting member 230, and the second connecting member 240 to continue moving toward the opening 21. When the mask body 100, the first connecting member 230, and the second connecting member 240 move to the locked position, the two locking tongues 250 are respectively aligned with the two locking tongue holes 202. At this time, the two locking tongues 250 are no longer squeezed and slide toward each other, i.e., pop out and extend into the locking tongue holes 202 on both sides, and engage with the locking tongue holes 202 on both sides, so that the first connecting member 230 and the second connecting member 240 can be quickly connected and fixed to the first hanging ear 210 and the second hanging ear 220, respectively.

[0075] Optionally, two locking tongue holes 202 can be respectively set on the two sides facing each other between the first hanging ear 210 and the second hanging ear 220, and when the mask body 100, the first connecting member 230 and the second connecting member 240 move to the locking position, the two locking tongues 250 can be respectively aligned with the two locking tongue holes 202 of the first hanging ear 210 and the two locking tongue holes 202 of the second hanging ear 220, each locking tongue 250 pops out and respectively engages with the two locking tongue holes 202 of the first hanging ear 210 and the two locking tongue holes 202 of the second hanging ear 220, thereby improving the connection stability between the first connecting member 230 and the first hanging ear 210 and the connection stability between the second connecting member 240 and the second hanging ear 220.

[0076] In order to ensure the stability of the internal structure of the first connecting member 230 and the second connecting member 240, the present application further proposes an implementation method, please continue to refer to Figure 7-11As shown in the figure, the first connecting member 230 and the second connecting member 240 each include a housing 231 and a fixing plate 232. One side of the housing 231 is fixedly connected to the outer frame 110, and the other side is provided with a first through hole 2311. The fixing plate 232 is disposed within the housing 231 and includes a bottom structure 2321 and sidewalls 2322 fixedly disposed on both sides of the bottom structure 2321. The bottom structure 2321 is fixedly connected to the housing 231, and a limited space 232a is formed between the two sidewalls 2322. The lock tongue 250 is partially disposed within the limited space 232a and can slide within the limited space 232a, so that the lock tongue 250 partially extends and retracts in the first through hole 2311 and engages with the lock tongue hole 202.

[0077] Specifically, to improve structural compactness, the embodiment of the present application disposes the switch assembly 300 inside the housing 231 of the first connector 230 or the second connector 240, so as to be drivingly connected to one end of each rotating shaft 120. In this case, to prevent the sliding lock tongue 250 from colliding with the switch assembly 300, a fixing plate 232 is disposed within the housing 231 to separate the lock tongue 250 from the switch assembly 300.

[0078] The bottom structure 2321 can be connected and fixed to the housing 231 by bonding, welding, or threaded connection. The locking tongue 250 is partially disposed in the limited space 232a formed by the two side walls 2322 of the fixing plate 232 and slides in the limited space 232a. When the locking tongue 250 slides in the limited space 232a in a direction away from the mask body 100, the portion of the locking tongue 250 can extend from the first through hole 2311 and engage with the locking tongue hole 202. When the locking tongue 250 slides toward the mask body 100 in the limited space 232a, the portion of the locking tongue 250 extending from the first through hole 2311 retracts, thereby releasing the locking tongue 250 from the locking tongue hole 202.

[0079] By limiting the sliding of the lock tongue 250 within the limiting space 232 a , collision between the sliding lock tongue 250 and the switch assembly 300 can be avoided, thereby ensuring the stability of the internal structure of the first connecting member 230 or the second connecting member 240 .

[0080] In order to quickly remove the mask body 100, the first connecting member 230 and the second connecting member 240 from the chassis 20, the present application further proposes an embodiment, please continue to refer to Figure 7 and Figure 11As shown in the figure, a second through hole 2312 is formed at each end of the housing 231, and a first inclined surface 251 is provided at each end of the lock tongue 250. The first connecting member 230 and the second connecting member 240 further include two pressable key modules 260, which are respectively provided at each end of the lock tongue 250. The portion of the key module 260 extending into the housing 231 through the second through hole 2312 is provided with a second inclined surface 261a that abuts the first inclined surface 251. A first elastic member 233 is provided at each end of the fixing plate 232, and the first elastic member 233 is fixedly connected to the portion of the key module 260 located within the housing 231. A second elastic member 234 is fixedly provided between the side of the lock tongue 250 facing away from the housing and the side wall 2322 of the fixing plate 232. The button module 260 is used to move toward each other when it is pressed, so that the two lock tongues 250 move away from each other under the push of the button module 260. The button module 260 is used to move away from each other under the action of the first elastic member 233 when it is released, so that the two lock tongues 250 move toward each other under the action of the second elastic member 234.

[0081] like Figure 9 and Figure 10 As shown, the first elastic member 233 and the second elastic member 234 can be springs, and the key module 260 can include a guide block 261 and a key 262, wherein the key 262 can be pressed. Specifically, the key 262 is arranged outside the housing 231, and a slot is provided on the side of the key 262 facing the housing 231. The guide block 261 is arranged inside the housing 231 and is located between the fixing plate 232 and the housing 131. The guide block 261 has a through hole at a position corresponding to the slot, so that the first elastic member 233 can pass through the through hole of the guide block 261 and one end of the first elastic member 233 can be embedded in the slot of the key 262, fixedly connected to the key 262, so that the first elastic member 233 is compressed when the key 262 is pressed.

[0082] A second inclined surface 261a is extended from one side of the guide block 261 to abut against the first inclined surface 251. When the buttons 262 of the two button modules 260 are pressed at the same time, the two first elastic members 233 are compressed, so that the two guide blocks 261 can move toward each other, thereby pushing the two lock tongues 250 to move away from each other, so that the two second elastic members 234 are compressed; when the buttons 262 of the two button modules 260 are released, the two first elastic members 233 rebound, driving the two guide blocks 261 to move away from each other and pushing the buttons 262 of the two button modules 260 to recover, so that the two second elastic members 234 rebound and push the two lock tongues 250 to move toward each other.

[0083] By pressing the key module 260 to compress the first elastic member 233, the two locking tongues 250 move toward each other under the push of the key module 260, and the mask body 100, the first connecting member 230, and the second connecting member 240 can be quickly connected and fixed to the side of the chassis 20 provided with the opening 21, or the mask body 100, the first connecting member 230, and the second connecting member 240 can be quickly removed from the chassis 20. By releasing the key module 260, the key module 260 moves away from each other under the rebound action of the first elastic member 233, and the two locking tongues 250 can move toward each other under the rebound action of the second elastic member 234, and then engage with the two locking tongue holes 202, connecting and fixing the first hanging ear 210 to the first connecting member 230, and the second hanging ear 220 to the second connecting member 240.

[0084] In order to ensure the sliding stability of the lock tongue 250, this application further proposes an implementation method, please continue to refer to Figure 7-11 The fixed plate 232 further includes a guide member 2323 extending in the direction in which the locking tongue 250 is extended and retracted, and the two ends of the guide member 2323 are respectively fixedly connected to the two side walls 2322 of the fixed plate 232. The locking tongue 250 is provided with a fourth through hole 252, through which the locking tongue 250 is sleeved on the guide member 2323 to slide along the guide member 2323 for extension and retraction.

[0085] Among them, the two ends of the guide member 2323 can be connected and fixed to the two side walls 2322 of the fixed plate 232 by welding, or by opening corresponding pin holes on the two side walls 2322 of the fixed plate 232 and knocking the guide member 2323 into the two pin holes in turn, so that the two ends of the guide member 2323 can be connected and fixed to the two side walls 2322 of the fixed plate 232.

[0086] The guide member 2323 can be a cylinder or a prism, and the fourth through hole 252 can be adapted to the guide member 2323 as a circular hole, a rectangular hole or a polygonal hole, so that after the lock tongue 250 is sleeved on the guide member 2323, the guide member 2323 can play a guiding role, so that the two lock tongues 250 can slide smoothly away from or towards each other along the two guide members 2323 respectively.

[0087] In order to further improve the security of the hard disk and the motherboard in the chassis 20, this application further proposes an implementation method, please continue to refer to Figure 2 、 Figure 8 、 Figure 10 and Figure 11As shown in the figure, the second connecting member 240 further includes a lock assembly 241, which is disposed on the side of the lock tongue 250 facing the mask body 100. The lock assembly 241 is rotatably connected to the housing 231 of the second connecting member 240. The lock assembly 241 is configured to rotate to a locking angle and abut against the lock tongue 250 after the lock tongue 250 is engaged with the lock tongue hole 202, thereby restricting the lock tongue 250 from moving toward the mask body 100.

[0088] Specifically, the lock assembly 241 may include a lock 2411, a first nut 2412, a locking plate 2413, and a second nut 2414. One end of the lock 2411 can be inserted with a corresponding key and rotated with the key, while the other end can be a threaded rod. A through hole can be provided in the housing 231 of the second connector 240, and the threaded rod of the lock 2411 can be passed through the through hole and threadedly engaged with the first nut 2412 disposed within the housing 231 of the second connector 240, thereby rotatably connecting the lock 2411 to the housing 231 of the second connector 240. The locking plate 2413 is sleeved onto the threaded rod of the lock 2411, facing away from the through hole. The second nut 2414 is disposed on a side of the lock 2413 facing away from the first nut 2412 and threadedly engaged with the threaded rod of the lock 2411, allowing the lock 2413 to rotate with the key.

[0089] After the lock tongue 250 is engaged with the lock tongue hole 202, when the key is inserted into the lock head 2411 and rotated 90° counterclockwise, the lock plate 2413 will also rotate 90° counterclockwise and abut against the lock tongue 250, so that the lock tongue 250 cannot move toward the mask body 100, so that the lock tongue 250 is always engaged with the lock tongue hole 202, that is, the mask body 100, the first connecting member 230 and the second connecting member 240 are locked and cannot be removed. In the locked state, when the key is inserted into the lock head 2411 and rotated 90° clockwise, the lock plate 2413 rotates 90° clockwise and no longer abuts against the lock tongue 250. At this time, the key module 260 on the first connecting member 230 and the second connecting member 240 is pressed at the same time to make the two lock tongues 250 move away from each other, releasing the engagement with the lock tongue hole 202, and the mask body 100, the first connecting member 230 and the second connecting member 240 can be removed from the chassis 20.
