Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machine cases, in particular to a network security machine case. BACKGROUND

[0002] At present, users have higher and higher aesthetic requirements for the appearance of network security machine cases (i.e. a machine case specially designed to protect computer network equipment and data security).

[0003] Generally, in order to improve the appearance of the network security machine case, too many elements should not be arranged on the front panel in addition to the screen, LOGO (i.e. logo) and indicator light, so most IO ports (IO is the abbreviation of Input / Output, which means input / output) of the traditional network security machine case are arranged on the rear panel, and only a small number of IO ports that must be placed in front are allowed on the front panel.

[0004] Another case is that too many front modules of the traditional network security machine case result in that the number of IO ports cannot meet the demand, so that it is inconvenient to process information and operate the human-machine interface of the upper rack cabinet due to the small number of optional IO ports.

[0005] In summary, the traditional network security machine case still has some defects:

[0006] 1) The front panel is prone to insufficient IO port configuration due to the limitation of the available area.

[0007] 2) The appearance of the front panel and the number of IO ports cannot be considered (i.e. if the appearance of the traditional network security machine case needs to be improved, the number of IO ports must be reduced; if more interface requirements need to be met and it is convenient for users to operate and process information, the number of IO ports on the front panel must be increased, which results in a decrease in the appearance).

[0078] The front panel 21 is usually provided with elements such as a screen 211 and an indicator light, and the IO port 31 (Input / Output) designed on the stepping rotation device 1 is exposed on the front panel 21 of the case body 2.

[0079] In the present embodiment, the front panel 21 can be made of aluminum alloy material.

[0080] The control component at least includes a switch 4 and an MCU chip (Microcontroller Unit).

[0081] The electrical principle of the network security case 100 is described in detail as follows: firstly, the IO door 142 is closed to release the fool-proof function; secondly, the switch 4 of the control component is pressed to form an electrical signal; then, the electrical signal is transmitted to the MCU chip, and voltage information is formed after processing by the MCU chip; and then, the voltage information is transmitted to the motor, so that the motor 1211 rotates in a preset manner; wherein, each transmission of the voltage information can make the motor rotate a preset target number of turns (the target number of turns can be determined according to the gear transmission ratio, and each rotation makes the IO port 31 switch once, and after the IO port is switched, the distance sensor feeds back a count signal to the MCU chip as a successful count, and the motor 1211 reverses after accumulating three times, and the cycle is repeated).

[0082] The case body 2 has an accommodating space formed inside; and the front panel 21 is provided with a port insertion hole 212.

[0083] In addition, the stepping rotation device 1 is fixed on the case body 2 and located in the accommodating space; and the mounting position of the stepping rotation device 1 is close to the front panel 21.

[0084] In addition, the board card 3 has a plurality of different IO ports 31, and the plurality of different IO ports 31 are arranged along the circumference of the board card 3; and any one of the plurality of different IO ports 31 can be exposed at the port insertion hole 212.

[0085] Specifically, the control component is arranged on the case body 2 and can be used to control at least a part of the stepping rotation device 1 to rotate in a preset manner.

[0086] It should be noted that the board card 3 is fixed on at least a part of the stepping rotation device 1, so that the board card 3 can rotate with at least a part of the stepping rotation device 1, thereby switching the IO port 31 exposed at the port insertion hole.

[0087] In some embodiments, as shown in Figure 3 and Figure 4 The stepping rotation device 1 comprises a bottom shell 11 with a first opening, a stepping rotation module 12, a top cover 13 and an IO rotation head 14.

[0088] It can be understood that the bottom shell 11 has an accommodating cavity formed inside and the accommodating cavity is in communication with the first opening.

[0089] In the embodiment of the present application, the step-rotation module 12 is arranged in the accommodating cavity, the top cover 13 is arranged at the first opening of the bottom shell 11, and the IO rotary head 14 is arranged on the top cover 13.

[0090] In some embodiments, in combination with Figure 3 、 Figure 4 and Figure 7 , it can be seen that the IO rotary head 14 comprises a frame body 141 with a second opening, four IO doors 142, and a fixing disc 143.

[0091] The frame body 141 is internally formed with an accommodating cavity, and the accommodating cavity is in communication with the second opening.

[0092] In addition, the four IO doors 142 are arranged on the four circumferential surfaces of the frame body 141, and each IO door 142 can be switched between an open state and a closed state.

[0093] In addition, the fixing disc 143 is connected to the bottom of the frame body 141 away from the second opening, and the fixing disc 143 is provided with a first through hole 1431 and a plurality of second through holes 1432.

[0094] Specifically, the first through hole 1431 is coaxially arranged with the fixing disc 143, and the plurality of second through holes 1432 are arranged on the circumferential edge of the fixing disc 143.

[0095] In some embodiments, in combination with Figure 7 , it can be seen that the frame body 141 is provided with a first flange 1411 and a second flange 1412 extending towards the outside of the accommodating cavity on the circumferential outer surface.

[0096] It can be understood that the first flange 1411 is located at one end of the second opening, and the second flange 1412 is arranged at the end away from the second opening; the second flange 1412 is provided with a plurality of shaft sleeves 1413 corresponding to the plurality of second through holes 1432.

[0097] It should be noted that the surface of the first flange 1411, the surface of the second flange 1412, and the circumferential outer surface of the frame body 141 form a limiting groove, and the four IO doors 142 are accommodated in the limiting groove.

[0098] Specifically, a plurality of different IO ports 31 can respectively extend out of the circumferential surface of the frame body 141, so that each surface of the frame body 141 in the circumferential direction can expose the corresponding IO port 31.

[0099] In some embodiments, according to Figure 3 and Figure 4 , it can be seen that the bottom shell 11 comprises a bottom plate 111 and a plurality of side plates 112.

[0100] The bottom plate 111 has a first surface and a second surface facing away from each other; the plurality of side plates 112 protrude from the first surface of the bottom plate 111, and the second surface of the bottom plate 111 abuts against the case body 2.

[0101] In addition, the bottom plate 111 and the plurality of side plates 112 enclose a containing space.

[0102] In some embodiments, as shown in Figure 6 The top cover 13 includes a cover plate 131, a control disc 132, and a pair of fixing seats 133.

[0103] Specifically, the cover plate 131 covers the first opening of the bottom shell 11, and the control disc 132 is located between the pair of fixing seats 133.

[0104] Specifically, the pair of fixing seats 133 serves to fix the IO rotary head 14; when the IO rotary head 14 is fixed, the sliding groove 1331 is embedded with the second flange 1412 on the IO rotary head 14.

[0105] In the embodiments of the present application, the control disc 132 is provided with a first pin shaft 1321, a second pin shaft 1322, and a pair of first sleeve shafts 1323; the first pin shaft 1321 and the second pin shaft 1322 protrude from the two surfaces of the control disc 132 opposite in the first direction 1001, and the first direction 1001 is the axial direction of the control disc 132.

[0106] It can be understood that the cover plate 131 is provided with a first positioning hole 1311 and a pair of second positioning holes 1312, and the first positioning hole 1311 is located between the pair of second positioning holes 1312.

[0107] In some embodiments, referring to Figure 6 The first pin shaft 1321 is inserted into the first positioning hole 1311 to guide the control disc 132 to move relative to the cover plate 131 along the first direction 1001; the first pin shaft 1321 is located between the pair of first sleeve shafts 1323.

[0108] The pair of first sleeve shafts 1323 are inserted into the pair of second positioning holes 1312 to limit the control disc 132 from rotating relative to the cover plate 131.

[0109] In addition, the fixing disc 143 can be connected with the control disc 132 through the cooperation between the first through hole 1431 and the second pin shaft 1322.

[0110] In some embodiments, in combination with Figures 3-7 It can be known that one of the plurality of side plates 112 is provided with a debugging observation hole 1121; the stepping rotation module 12 includes a driving component 121, a driven component 122, and a reversing component 123.

[0111] Specifically, the driving component 121 is fixedly installed on the cover plate 131 of the top cover 13 and located in the accommodating cavity; at least a part of the driving component 121 is exposed at the debugging observation hole 1121.

[0112] In addition, the driving component 122 cooperates with the driving component 121, and the reversing component 123 cooperates with the driving component 122, so that the reversing component 123 rotates in a preset manner.

[0113] Furthermore, at least a part of the reversing component 123 is connected with the frame 141, so that the frame 141 can rotate synchronously with the rotation of the reversing component 123.

[0114] In some embodiments, referring to Figure 3 and Figure 5 The driving component 122 comprises a first transmission shaft 1221, a driven gear 1222 and a driving disc 1223.

[0115] In the embodiments of the present application, the first transmission shaft 1221 is fixed on the bottom shell 11; the driven gear 1222 and the driving disc 1223 are both fixed on the first transmission shaft 1221, and the driving disc 1223 is located above the driven gear 1222.

[0116] Specifically, the driving component 121 comprises a motor 1211 and a driving gear 1212; the motor 1211 is fixed on the bottom shell 11; the driving gear 1212 is fixedly connected with the motor 1211, and the driving gear 1212 is exposed at the debugging observation hole 1121; the driving gear 1212 and the driven gear 1222 are in meshing engagement, so as to drive the driving disc 1223 to rotate.

[0117] The driving component composed of the motor 1211 and the driving gear 1212 can serve as a power source of the step rotation module 12; in addition, during the movement of the step rotation module 12, the motor 1211 drives the driving gear 1212 to rotate, then drives the driven gear 1222 to rotate, and drives the driving disc 1223 to rotate through the first transmission shaft 1221; during the rotation of the driving disc 1223, the driving column 1226 on the driving disc 1223 drives the reversing wheel 1232 to rotate 90° through the reversing groove 1234 on the reversing wheel 1232; at the same time, when the reversing wheel 1232 rotates 90°, the second transmission shaft 1231 and the slot hole 1414 in the center of the frame 141 are in engagement, so as to drive the entire IO rotating head 14 to rotate 90°, thereby realizing the conversion of IO ports 31 of different types or different functions.

[0118] The driving gear 1212 is exposed at the debugging observation hole 1121, which can facilitate the user to observe the forward and reverse rotation of the motor 1211 during electrical debugging.

[0119] It should be explained that the transition boss 1224, the limiting flange 1225 and the driving column 1226 are arranged on the main driving disc 1223; the limiting flange 1225 protrudes from the outer edge surface of the transition boss 1224 and is located at the top of the transition boss 1224; the transition boss 1224 and the limiting flange 1225 are both provided with corresponding first concave arc-shaped grooves 1227, and the installation position of the driving column 1226 corresponds to the first concave arc-shaped grooves 1227.

[0120] In some embodiments, as shown in Figures 3-5 The reversing component 123 includes a second transmission shaft 1231 and a reversing wheel 1232.

[0121] The second transmission shaft 1231 is fixed on the bottom shell 11, and the reversing wheel 1232 is fixed on the second transmission shaft 1231; the reversing wheel 1232 is located below the limiting flange 1225.

[0122] In addition, the second transmission shaft 1231 can be fixedly connected with the control disc 132, so that the control disc 132 and the second transmission shaft 1231 can move in the axial direction of the control disc 132.

[0123] In addition, the circumferential outer edge of the reversing wheel 1232 is provided with a second concave arc-shaped groove 1233; the reversing wheel 1232 is provided with four reversing grooves 1234, and the interval between adjacent two reversing grooves 1234 is 90°.

[0124] In some embodiments, according to Figures 3-5 It can be known that when the outer edge surface of the transition boss 1224 abuts against the second concave arc-shaped groove 1233 of the reversing wheel 1232, the driving column 1226 and the reversing groove 1234 are separated from each other.

[0125] It can be understood that when the first concave arc-shaped groove 1227 corresponds to the second concave arc-shaped groove 1233, the driving column 1226 is inserted into the reversing groove 1234, and drives the reversing wheel 1232 to rotate 90°, so that the IO rotating head 14 rotates 90° synchronously with the reversing wheel 1232, thereby switching the IO port 31 exposed at the port jack.

[0126] In some embodiments, according to Figures 3-7 It can be known that the second transmission shaft 1231 is provided with a cavity at one end close to the cabinet body 2; the network security cabinet 100 further includes a foolproof component 5.

[0127] Specifically, the foolproof component 5 is composed of a first spring 51, a plurality of second springs 52 and a plurality of second sleeve shafts 53.

[0128] It should be explained that one end of the first spring 51 extends into the cavity of the second transmission shaft 1231, and the other end abuts against the cabinet body 2, which can provide a first elastic force for driving the second transmission shaft 1231 to move upward.

[0129] It is further explained that the frame body 141 is provided with an IO door 142 on each side, and the IO door 142 is turned over through a door shaft 1421; wherein the first flange 1411 and the second flange 1412 play a limiting role, and the door handle 1422 can be used to switch the closed state or the open state of the door.

[0130] In the embodiment of the present application, one end of the second shaft sleeve 53 extends into the shaft sleeve 1413, and the other end penetrates out of the second through hole 1432.

[0131] Specifically, the second spring 52 is sleeved on the second shaft sleeve 53, and the second spring 52 can abut against the surface of the fixed disc 143; the second spring 52 has a second elastic force for limiting the downward movement of the second shaft sleeve 53.

[0132] In some embodiments, please continue to refer to Figures 3-7 When the IO door 142 exposed at the port jack is switched to the closed state, the second shaft sleeve 53 moves downward to press the control disc 132 to move downward, thereby driving the second transmission shaft 1231 to move downward; at this time, the driving column 1226 can be inserted into the reversing groove 1234;

[0133] Moreover, when the IO door 142 exposed at the port jack is switched to the open state, the second spring 52 provides a second elastic force to drive the second shaft sleeve 53 to move upward, and the first spring 51 provides a first elastic force to drive the second transmission shaft 1231 to move upward, thereby driving the control disc 132 to move upward; at this time, the driving column 1226 cannot be inserted into the reversing groove 1234.

[0134] In combination with Figures 1-7The working principle of the fool-proof function is described in detail as follows: first, the second shaft 53 is inserted into the shaft sleeve 1413 of the frame 141 from bottom to top; then, the second spring 52 is sleeved on the second shaft 53; then, the fixing disc 143 is covered on the bottom of the frame 141 (the bottom of the frame 141 is the end where the second flange 1412 is located); at the same time, one end of the second shaft 53 extends out of the surface of the second flange 1412 after extending into the shaft sleeve 1413, and the other end of the second shaft 53 passes through the first through hole 1431 of the fixing disc 143; when the IO door 142 is switched to the closed state, the second shaft 53 moves downward, so that the end of the second shaft 53 abuts against the surface of the control disc 132, and the end of the second shaft 53 presses the control disc 132, thereby driving the second transmission shaft 1231 to move downward (at this time, the second spring 52 is in a compressed state), and the result of the downward movement of the second transmission shaft 1231 is that the reversing wheel 1232 can contact the driving column 1226; at this time, the switch 4 is pressed, and under the action of the motor 1211 and the first transmission shaft 1221, the driving disc 1223 is forced to rotate, the reversing wheel 1232 is rotated by 90°, and finally the 90° switching of the IO rotary head 14 is completed; in addition, when the IO door 142 is switched to the open state, the second shaft 53 moves upward under the action of the second spring 52, so that the second shaft 53 and the surface of the control disc 132 are separated from each other, and under the action of the first spring 51, the second transmission shaft 1231 and the reversing wheel 1232 move upward, at this time, the reversing wheel 1232 cannot contact the driving column 1226, even if the switch 4 is pressed, the motor 1211 is in idle running, and the IO rotary head 14 cannot be rotated, thereby realizing the fool-proof function.

[0135] The above-mentioned fool-proof function can prevent the user from starting to rotate when the connection cable of the IO port 31 is not pulled out, thereby avoiding damage to the IO port 31 (only when the IO door 142 is in the closed state and the above-mentioned connection cable is pulled out, the switch 4 is pressed, and the switching of the IO port 31 can be realized).

[0136] In summary, the network security case provided by the embodiment of the application can switch the IO ports exposed at the port jacks by adding the stepping rotation device and the board card with a plurality of IO ports, and the board card can rotate at least partially with the stepping rotation device, so that the IO ports exposed at the port jacks can be switched. Since the board card can integrate more IO ports in the limited available area of the front panel, and different IO port types can be switched by the stepping rotation device, not only the technical problem that the IO ports cannot be configured in sufficient quantity due to the limitation of the available area of the front panel can be solved, but also the technical problem that the appearance of the front panel and the number of IO ports cannot be considered can be solved. Therefore, the network security case provided by the embodiment of the application has certain novelty compared with the traditional network security case.

[0137] The above description is further detailed in connection with specific / preferred embodiments of the present application, and cannot be deemed to limit the specific implementation of the present application to these descriptions. For those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
