Description

Technical Field

[0001] The present invention relates to the technical field of chassis, and in particular to a network security chassis. Background Art

[0002] At present, users have increasingly higher requirements for the aesthetics of the appearance of a network security chassis (that is, a network security chassis, which is a chassis designed specifically to ensure the security of computer network equipment and data).

[0003] Usually, in order to improve the appearance of the network security chassis, it is not advisable to set too many elements on the front panel except the screen, LOGO (logo) and indicator lights. Therefore, in order to ensure the appearance of the traditional network security chassis, most of the IO ports (IO is the abbreviation of Input / Output, indicating input and output) are set on the back panel, and the front panel only allows a small number of IO ports that must be placed in the front.

[0004] Another situation is that the traditional network security chassis has too many front-end modules, resulting in the number of IO ports being unable to meet demand. As a result, due to the small number of optional IO ports, it is inconvenient to process information and operate the human-machine interface of the rack cabinet.

[0005] In summary, traditional network security chassis still have some defects:

[0006] 1) Due to the limited available area on the front panel, it is easy to cause insufficient configuration of IO ports.

[0007] 2) The appearance of the front panel and the number of IO ports cannot be taken into account at the same time (that is, if you need to improve the appearance of the traditional network security chassis, you must set up fewer IO ports; if you need to meet more interface requirements and facilitate user operation and information processing, you have to increase the number of IO ports on the front panel, which will lead to a decrease in appearance).

[0078] The front panel 21 is usually provided with elements such as a screen 211 and indicator lights. The chassis body 2 needs to design an IO port 31 (Input / Output) exposed on the front panel 21 on the stepping rotary device 1 .

[0079] In the embodiment of the present application, 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, a highly integrated circuit chip).

[0081] The electrical principle of the network security chassis 100 is described in detail: first, close the IO door 142 to disable the anti-foolproof function; second, press the switch 4 of the control component to form an electrical signal; then, transmit the above electrical signal to the MCU chip, and form voltage information after being processed by the MCU chip; thereafter, transmit the above voltage information to the motor to make the motor 1211 rotate in a preset situation; wherein, each transmission of voltage information can make the motor rotate a preset target number of circles (the target number of circles can be determined based on the gear transmission ratio, and each rotation causes the IO port 31 to switch once. After switching the IO port, the distance sensor feeds back a counting signal to the MCU chip as a successful count, and after accumulating three counts, the motor 1211 reverses, and this cycle is repeated).

[0082] The chassis body 2 has a storage space formed inside, and the front panel 21 is provided with a port jack 212 .

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

[0094] Specifically, the first through hole 1431 is coaxially disposed with the fixing disk 143 , and a plurality of second through holes 1432 are disposed at a circumferential edge of the fixing disk 143 .

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

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

[0107] In some embodiments, please refer to Figure 6 The first pin shaft 1321 is inserted into the first positioning hole 1311 to guide the control disk 132 to move relative to the cover plate 131 along the first direction 1001 ; the first pin shaft 1321 is located between a 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 disk 132 from rotating relative to the cover plate 131 .

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

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

[0113] Moreover, at least a portion of the switching component 123 is connected to the frame 141 , so that the frame 141 can rotate synchronously with the rotation of the switching component 123 .

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

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

[0124] In some embodiments, according to Figure 3-Figure 5 It can be seen that when the outer edge surface of the transition boss 1224 abuts against the second concave arc 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 groove 1227 corresponds to the second concave arc 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 follows the reversing wheel 1232 to rotate 90° synchronously, thereby switching the IO port 31 exposed at the port jack.

[0126] In some embodiments, Figure 3-Figure 7 It can be seen that a cavity is opened at one end of the second transmission shaft 1231 close to the chassis body 2; the network security chassis 100 also includes: an anti-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 noted 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 chassis body 2 , thereby providing a first elastic force for driving the second transmission shaft 1231 to move upward.

[0129] To further explain, each of the four sides of the frame 141 is provided with an IO door 142, and the IO door 142 is flipped over by 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 between a closed state and an open state.

[0130] In the embodiment of the present application, one end of the second sleeve shaft 53 extends into the sleeve 1413 , and the other end passes through the first through hole 1431 .

[0131] Specifically, the second spring 52 is sleeved on the second sleeve shaft 53 , and the second spring 52 can abut against the surface of the fixed plate 143 ; the second spring 52 has a second elastic force that limits the second sleeve shaft 53 from moving downward.

[0132] In some embodiments, please refer to Figure 3-Figure 7 When the IO door 142 exposed at the port jack is switched to the closed state, the second sleeve shaft 53 moves downward to press the control disk 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 an open state, the second spring 52 provides a second elastic force to drive the second sleeve shaft 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 disk 132 to move upward; at this time, the drive column 1226 cannot be inserted into the reversing groove 1234.

[0134] Combination Figure 1-Figure 7, the working principle of the foolproof function is described in detail: first, the second sleeve shaft 53 is inserted into the sleeve 1413 of the frame body 141 from bottom to top; then, the second spring 52 is sleeved on the second sleeve shaft 53; thereafter, the fixing plate 143 is covered on the bottom of the frame body 141 (the bottom of the frame body 141 is the end where the second flange 1412 is located); at the same time, one end of the second sleeve shaft 53 extends into the sleeve 1413 and then extends out of the surface of the second flange 1412, while the other end of the second sleeve shaft 53 passes through the first through hole 1431 of the fixing plate 143; wherein, if the IO door 142 is switched to the closed state, the second sleeve shaft 53 moves downward, so that the end of the second sleeve shaft 53 abuts against the surface of the control plate 132, and the end of the second sleeve shaft 53 squeezes the control plate 132, thereby driving the second transmission shaft 1231 to move downward (at this time, the second spring 5 2 is in a compressed state), the result of the second transmission shaft 1231 moving downward is that the reversing wheel 1232 is in contact with 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 active disk 1223 is forced to rotate, driving the reversing wheel 1232 to rotate 90°, and finally completing the 90° switching of the IO rotating head 14; in addition, if the IO door 142 is switched to the open door state, the second sleeve shaft 53 moves upward under the action of the second spring 52, so that the second sleeve shaft 53 and the surface of the control disk 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, and at this time the reversing wheel 1232 is not in contact with the driving column 1226, and even if the switch 4 is pressed, the motor 1211 is in idling and cannot drive the IO rotating head 14 to rotate, thereby realizing the anti-foolproof function.

[0135] The foolproof function can prevent the user from starting to rotate when the connection cable of the IO port 31 is not unplugged, thereby avoiding damage to the IO port 31 (only when the IO door 142 is in a closed state and the connection cable end is unplugged, the switch 4 can be pressed to realize the switching of the IO port 31).

[0136] In summary, the network security chassis provided by the embodiment of the present invention can switch the IO ports exposed at the port jack by adding a stepping rotary device and a board with several IO ports, and the board can rotate at least partially following the stepping rotary device; because the board can integrate more IO ports in the limited available area of ​​the front panel, and different IO port types can be switched through the stepping rotary device, it can not only solve the technical problem that the IO ports cannot be fully configured due to the limited available area of ​​the front panel, but also solve the technical problem that the appearance of the front panel and the number of IO ports cannot be taken into account. Therefore, the network security chassis provided by the embodiment of the present invention has certain novelty compared with the traditional network security chassis.

[0137] The above contents are further detailed descriptions of the present invention in combination with specific / preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
