Description

Technical Field

[0001] The present invention relates to the technical field of network devices, and in particular to a portable anti-traceability secure Internet access device. Background Art

[0002] The portable anti-traceability installed Internet access device uses a solid-state switch reading and writing medium with various control functions to connect to the information security of an independent host system, physically isolating and blocking all network connections that may potentially attack the internal network. There is no physical connection, logical connection, or information transmission protocol for communication between systems, and there is no information exchange based on the protocol, preventing external attackers from directly invading, attacking, or damaging the internal network and ensuring the security of the internal host. Some anti-traceability installed Internet access devices usually use security routing devices, which are integrated in a box. A gateway is provided outside the box for connecting to the built-in CPU and motherboard. When in use, the network device can be plugged into the gateway through a line for use. The gateway plug interface of this device is directly exposed. Similarly, during its use, especially after the gateway is connected to the host, the load on the CPU and motherboard increases, resulting in a certain amount of heat generation. To improve heat dissipation, heat dissipation ports are generally provided on its surface, and the provided heat dissipation ports are also directly exposed. Currently, during both carrying and normal use, no corresponding protective structure is provided. When it is placed idle or carried, external impurities may enter and cause damage to its internal interface. Therefore, we have designed a portable anti-traceability secure Internet access device.

[0014] Beneficial effects of the present invention: 1. By setting a shielding member on the insertion interface of the anti-traceability and secure Internet access device and a protection mechanism in its heat dissipation port, when the device is not plugged into the gateway, the shielding member can shield and protect the insertion interface, while the protection mechanism can shield the heat dissipation port. During the process of carrying and placing, both the heat dissipation port and the insertion interface of the device are blocked, preventing external dust and impurities from entering its interior, ensuring the safety of the insertion interface, and preventing dust accumulation inside the device. 2. By setting a liftable support structure inside the device, which cooperates with the protection mechanism, the support structure must be pushed out before the device is plugged into the gateway, making it suspended from the placement desktop, which can improve the ventilation effect at the bottom, reduce interference from ground obstacles, expand the signal coverage range, improve the network penetration effect, and prevent people from forgetting to open the support structure due to carelessness. 3.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1 - Figure 10 A portable anti-tracing secure Internet access device comprises an outer frame 1, a mainboard 5 is installed at the bottom of the inner part of the outer frame 1, a head seat 2 is screwed to the left end of the outer frame 1, a connecting terminal 21 is embedded in the head seat 2, the connecting terminal 21 is electrically connected to the mainboard 5, a power switch and a gateway plug interface are integrated on the connecting terminal 21, and a plurality of shielding members 3 are rotatably installed on the head seat 2, and the plurality of shielding members 3 shield the plurality of plug interfaces respectively; A protective mechanism 7 is slidably installed on both the front and rear sides of the outer frame 1. The left ends of the two protective mechanisms 7 are connected to the pushing structure 6. The pushing structure 6 is in sliding contact with the shielding member 3. A supporting structure 8 for supporting the outer frame 1 is installed inside the outer frame 1.

[0019] Reference Figure 1 - Figure 5, the shielding member 3 includes a shielding plate 31 rotatably mounted on the head base 2 through a shaft seat and a shaft pin 33. An arc-shaped pushing head 32 is provided above the shielding plate 31. The inner end of the pushing head 32 is designed with an inclined surface to form a pushing surface. Both ends of the shaft pin 33 are provided with torsion springs 34. The two ends of the torsion spring 34 are respectively fixed to the shielding plate 31 and the shaft seat. The shaft pin 33 is inserted through the upper end of the shielding plate 31. The torsion spring 34 makes the shielding plate 31 always tend to move downward. When the gateway inserted into the insertion port is pulled out, the shielding plate 31 will automatically deflect downward under the action of the torsion spring 34, thereby blocking the insertion port and preventing foreign objects from entering; A plurality of openings are formed through the left and right sides above the head base 2. The upper ends of the plurality of pushing heads 32 respectively pass through the plurality of openings and are located inside the outer frame 1.

[0020] Refer to Figure 4 - Figure 7 , the pushing structure 6 includes two reset members 62 slidably mounted on the inner walls of the front and rear sides of the outer frame 1 through linear tracks. A cross bar 61 is fixed between the two reset members 62. A plurality of pushing blocks 63 are fixed on the cross bar 61. The positions of the plurality of pushing blocks 63 correspond to the positions of the plurality of pushing heads 32 one by one. And the end of the pushing block 63 close to the pushing head 32 is designed with an inclined surface to form a pushing inclined surface 631. When the shielding plate 31 rotates upward and unfolds, the pushing head 32 located at the top of the shielding plate 31 will deflect clockwise with the shaft pin 33 as the axis. The pushing surface of the clockwise-deflected pushing head 32 will contact the pushing inclined surface 631 of the pushing block 63, thereby pushing the cross bar 61 and the two reset members 62 to move away from the head base 2 and move to the right. And the plurality of shielding members 3 are all designed as independent modules. When any one of them is opened, it can make the pushing structure 6 move to the right.

[0021] Refer to Figure 3 - Figure 9 , the protection mechanism 7 includes two blocking members 71 slidably mounted on the inner walls of the front and rear sides of the outer frame 1. The left end of the blocking member 71 is connected to the reset member 62 through a reset structure. The inner end of the blocking member 71 is slidably mounted with an isolation member 72 left and right. The left end of the isolation member 72 is provided with a swing frame 73 for driving it to swing left and right. A limiting member 74 for limiting the protection mechanism 7 is provided on the left side of the blocking member 71.

[0022] A plurality of heat dissipation openings 11 are provided at equal intervals on both the front and rear sides of the outer frame 1. A discharge opening 12 with a strip-shaped structure is provided below the plurality of heat dissipation openings 11 on the same side. The plugging member 71 includes a plugging frame 711 slidably installed on the inner wall of the outer frame 1. A plurality of plugging strips 712 are provided at equal intervals inside the plugging frame 711. A brush is provided on the inner side of the plugging strip 712. The length and width of the plugging strip 712 are both greater than the length and width of the heat dissipation opening 11. The bottom end of the discharge opening 12 is below the bottom end of the plugging strip 712, and the top end of the discharge opening 12 is above the bottom end of the plugging strip 712. A convex-shaped chute is provided on the surface of the plugging frame 711 that fits the outer frame 1. A slider is slidably provided in the chute, and the slider is fixed to the inner wall of the outer frame 1, so that the plugging frame 711 can slide along the inner wall of the outer frame 1; The length of the discharge opening 12 is less than the length of the plugging frame 711. The bottom ends of the inside of the plugging frame 711 and the bottom end of the discharge opening 12 are both designed with inclined surfaces. And the height of the side of the plugging frame 711 close to the inner wall of the outer frame 1 is lower than the height of the side away from the inner wall of the outer frame 1. The height of the inner bottom end of the discharge opening 12 is lower than the height of the side of the plugging frame 711 close to the outer frame 1. And the height of the outer bottom end of the discharge opening 12 is lower than the height of its inner bottom end. The impurities and dust at the bottom end inside the plugging frame 711 can slide into the discharge opening 12 and then be discharged through the discharge opening 12. When the plugging frame 711 is at the leftmost end, the plurality of plugging strips 712 are respectively in the front of the plurality of heat dissipation openings 11, so as to be able to block and seal the heat dissipation openings 11. When the plugging frame 711 is at the rightmost end, there is a dislocation between the plugging strip 712 and the heat dissipation opening 11, so that the heat dissipation opening 11 is exposed.

[0023] Refer to Figure 6 - Figure 9 The reset structure includes a connecting plate 716 fixed to the left end of the plugging frame 711. A reset rod 715 is fixed on the connecting plate 716. The other end of the reset rod 715 is fixed to the reset member 62. A fixing plate 714 is fixed inside the outer frame 1. The reset rod 715 is slidably inserted into the fixing plate 714. A reset spring 713 is sleeved on the reset rod 715. The two ends of the reset spring 713 are respectively abutted against the fixing plate 714 and the reset member 62. The reset spring 713 makes the reset member 62 and the plugging member 71 always have a tendency to move to the left. When all the shutters 31 are closed, that is, the pushing head 32 releases the contact extrusion on the pushing block 63. At this time, the reset member 62 moves to the left under the action of the reset spring 713, and the plugging member 71 and the isolating member 72 will also move a certain distance to the left, so that the plugging strip 712 blocks the heat dissipation opening 11.

[0024] Refer to Figure 6 - Figure 9, two L-shaped frames 717 are symmetrically and fixedly arranged at the upper and lower sides on the right side of the plugging frame 711. The isolation member 72 includes a sliding frame 721 slidably mounted on the surface of the plugging frame 711 away from the outer frame 1 in the left-right direction. A filter cloth 722 is fixed on the sliding frame 721, and the surface of the filter cloth 722 close to the plugging strip 712 is in sliding contact with the brush. Two abutting plates 723 are symmetrically and fixedly arranged at the upper and lower sides on the right side of the sliding frame 721. An abutting rod 725 is fixed on the abutting plate 723. The abutting rod 725 is slidably inserted into the L-shaped frame 717 in the left-right direction. An abutting spring 724 is sleeved on the abutting rod 725, and the two ends of the abutting spring 724 are respectively abutted against the abutting plate 723 and the L-shaped frame 717. Strip-shaped openings are formed in both the upper and lower parts of the sliding frame 721. A plurality of guide posts are fixedly arranged on both the upper and lower parts of the plugging frame 711. The guide posts are slidably inserted into the strip-shaped openings, and a ring is fixed at the front end of the guide post. The ring is in sliding contact with the surface of the sliding frame 721, so that the sliding frame 721 can slide left and right on the plugging frame 711; The elastic force of the abutting spring 724 is less than the elastic force of the reset spring 713. This enables the isolation member 72 not to have a large displacement in position when being extruded by an external force and moving rightward, and a relative displacement can still occur between the plugging member 71 and the isolation member 72; The abutting spring 724 makes the sliding frame 721 always tend to move leftward. When the sliding frame 721 is subjected to a force rightward, the sliding frame 721 will cause the filter cloth 722 to move rightward together, so that a relative sliding will occur between the filter cloth 722 and the brush. The brush will clean the surface of the filter cloth 722, making the attached impurities fall to the bottom end of the plugging frame 711 and flow out along the discharge port 12. For some dust that adheres to the inside and is difficult to slide off, the user can also manually clean it by inserting a brush into the discharge port 12.

[0025] Refer to Figure 4 - Figure 10 , the support structure 8 includes four fixing sleeves 86 fixedly arranged at the bottom of the outer frame 1 in a rectangular structure. A support rod 81 is slidably mounted up and down in the fixing sleeve 86. The bottom end of the support rod 81 passes through the outer frame 1 and is located below it. A toothed belt wheel 82 is rotatably mounted on the fixing sleeve 86 through a bearing. A threaded hole 821 is formed in the inner circle of the toothed belt wheel 82 by means of thread design. A threaded section 811 is formed at the upper end of the support rod 81 by means of thread design. The threaded section 811 is threadedly connected with the threaded hole 821, and the toothed belt wheels 82 are driven by a toothed belt 83. An annular groove is formed at the bottom end of the toothed belt wheel 82. A cylinder is rotatably inserted into the annular groove. The bottom end of the cylinder is welded to the fixing sleeve 86. A bearing is installed in the cylinder, and the bearing is also fixed to the annular groove; A vertically arranged guide hole is formed in the fixing sleeve 86. A guide block is arranged on the support rod 81. The guide block is slidably placed in the guide hole. When the toothed belt wheel 82 rotates, the support rod 81 will move upward or downward in a straight line under the cooperation of the threaded section 811 and the threaded hole 821.

[0026] A bevel gear 2 84 is fixed to the upper end of one of the toothed belt wheels 82, and the inner diameter of the bevel gear 2 84 is larger than the outer diameter of the support rod 81. A knob 4 is rotatably installed in the head seat 2 through a bearing, and the part of the knob 4 that passes through the head seat 2 and extends into the interior thereof is fixed with a bevel gear 1 41. The bevel gear 1 41 is meshed with the bevel gear 2 84 for transmission. Rotating the knob 4 clockwise can make the bevel gear 1 41 drive the bevel gear 2 84 to rotate clockwise, thereby making the toothed belt wheel 82 below rotate together. Since the four toothed belt wheels 82 rotate through the toothed belt 83, the four toothed belt wheels 82 can rotate together, thereby making the four support rods 81 move downward, so that the bottom of the device has a certain distance from the desktop, thereby improving the ventilation effect below it and preventing the heat from the desktop from being transferred to the device.

[0027] A driving member 85 is fixed to the top of each of the two left support rods 81. A limit block 851 and a toggle block 852 are fixed to the driving member 85. The toggle block 852 has an isosceles trapezoidal cross section. A plurality of equally spaced swing grooves 731 are provided on the surface of one side of the swing frame 73 close to the toggle block 852. The structure of the swing groove 731 is an isosceles trapezoidal structure, that is, the upper and lower surfaces of the swing groove 731 and the toggle block 852 close to each other are designed with inclined surfaces to form a push surface. When the toggle block 852 moves downward, the inclined surface below the toggle block 852 will move downward along the push surface below the swing groove 731, and push the swing frame 73 to drive the isolation member 72 to move together. When the toggle block 852 is out of the swing slot 731, the swing frame 73 is at the farthest end that it can move. When the toggle block 852 continues to move downward and aligns with the swing slot 731, the isolation member 72 moves to the left under the action of the abutment spring 724, so that the isolation member 72 can move back and forth left and right. The same is true when the toggle block 852 moves upward. The limiting member 74 penetrates upward and downward to form a limiting opening 741. When the blocking member 71 is at the far left end, the limiting opening 741 is directly below the limiting block 851. When the blocking member 71 is at the far right end, the limiting opening 741 and the support rod 81 are misaligned. That is, when the gateway needs to be plugged into the plug interface, the support rod 81 needs to be moved downward and extended through the knob 4 so that the limiting block 851 is disengaged from the limiting opening 741. Only then can the shield 31 be rotated clockwise and unfolded. In this way, the device must be placed in the air when in use. When the gateway is normally plugged in and used, the support rod 81 will not be retracted due to misoperation, thereby preventing the device from contacting the desktop.

[0028] Working principle: When the device needs to be carried, all the gateways inserted in the device are unplugged. Due to the torsion spring 34, the shield 31 always has a tendency to move downward. Under the action of the torsion spring 34, the shield 31 will be at the bottom. At this time, the push head 32 releases the contact and extrusion of the push block 63. The reset member 62 moves to the left under the action of the reset spring 713. The blocking member 71 and the isolation member 72 will also move to the left for a distance, so that the blocking strip 712 blocks the heat dissipation port 11. At this time, the heat dissipation port 11 on the device and the plug interface on the connection terminal 21 will be blocked; Then, turn the knob 4 counterclockwise to make the bevel gear 1 41 rotate together. The counterclockwise rotating bevel gear 1 41 will make the bevel gear 2 84 rotate counterclockwise, thereby making the lower toothed belt wheel 82 rotate together. Since the four toothed belt wheels 82 rotate through the toothed belt 83, the four toothed belt wheels 82 can rotate counterclockwise together, thereby making the four support rods 81 move upward, so that the four support rods 81 can be stored in the outer frame 1, reducing the volume of the entire device, making it easy to place it in a box or backpack for carrying, and in the process of carrying and placing, the heat dissipation port 11 and the plug interface of the device are blocked, and external dust and impurities cannot enter the interior, thereby ensuring the safety of the plug interface.

[0029] When the device is needed, the knob 4 is first turned clockwise. The clockwise turning knob 4 can make the bevel gear 1 41 drive the bevel gear 2 84 to rotate clockwise, so that the toothed belt wheel 82 below rotates clockwise together. Since the four toothed belt wheels 82 rotate through the toothed belt 83, the four toothed belt wheels 82 can rotate clockwise together, so that the four support rods 81 can move downward, so that the bottom of the device has a certain distance from the desktop, which improves the ventilation effect below, and also avoids the heat of the desktop from being transferred to the device, and the water stains on the desktop will not penetrate into the device; When the support rod 81 moves downward, the driving member 85 connected thereto moves downward together, and during the downward movement of the driving member 85, the inclined surface below the toggle block 852 moves downward along the push surface below the swing groove 731, and pushes the swing frame 73 to drive the isolation member 72 to move right together. When the toggle block 852 disengages from the swing groove 731, the swing frame 73 is at its maximum position, and the toggle block 852 continues to move downward and aligns with the swing groove 731, the isolation member 72 moves leftward under the action of the abutment spring 724, so that the toggle block 852 is constantly in contact with and out of contact with the swing groove 731, thereby enabling the isolation member 72 to move back and forth left and right. During the movement of the isolation member 72 back and forth left and right, the surface of the filter cloth 722 in the isolation member 72 will slide relative to the brush, and the brush will clean the surface of the filter cloth 722, causing the attached impurities to fall and flow out through the discharge port 12; When the support rod 81 is extended to the required maximum height, the limit block 851 on the driving member 85 is now separated from the limit opening 741 of the limit member 74 and is located below it (the toggle block 852 is now engaged in one of the swing grooves 731), and then the gateway can be plugged into the plug interface of the device for use; When one or more gateways are to be plugged into the plug interface, the shield 31 is first rotated upward clockwise. When the shield 31 is rotated upward and unfolded, the push head 32 located at the top of the shield 31 will deflect clockwise with the axle pin 33 as the axis, and the push surface of the clockwise deflected push head 32 will contact the push inclined surface 631 of the push block 63 and squeeze and push it to the right, thereby pushing the cross bar 61 and the two reset members 62 to move to the right away from the head seat 2. The reset member 62 moving to the right will move the entire blocking member 71 and the isolation member 72 to the left together through the reset rod 715 and the connecting plate 716, thereby causing the blocking strip 712 to be misaligned with the heat dissipation port 11, so that the heat dissipation port 11 is exposed; After the shield 31 is unfolded and the gateway is plugged into the socket, the bottom of the shield 31 contacts the gateway and cannot move down, which will ensure that the heat dissipation port 11 is always in an open state, thereby improving the ventilation effect inside the device, improving the heat dissipation effect, and reducing the temperature of the mainboard 5, so that it will not be frequency reduction or frame drop, thereby improving the network effect. At this time, the limit port 741 and the support rod 81 are misaligned, that is, the limit block 851 is blocked by the limit member 74 and cannot move up, thereby avoiding the support rod 81 from being stored due to misoperation. When the support rod 81 needs to be stored, all gateways can only be stored after being pulled out, forcing the device to be off the desktop when in use. This can improve the ventilation effect at the bottom, reduce interference from ground obstacles, expand signal coverage, and improve network penetration.

[0030] By setting a shielding member 3 on the plug interface of the anti-tracing secure Internet access device and setting a protective mechanism 7 in the heat dissipation port 11 thereof, when the device is not plugged into a gateway, the shielding member 3 can shield and protect the plug interface, and the protective mechanism 7 can shield the heat dissipation port 11. During the process of carrying and placing, the heat dissipation port 11 and the plug interface of the device are blocked, and dust and impurities from the outside cannot enter the inside thereof, thereby ensuring the safety of the plug interface and preventing dust from accumulating inside the device; By setting a liftable support structure 8 inside the device, the support structure 8 cooperates with the protection mechanism 7. Before the device is plugged into the gateway, the support structure 8 must be pushed out to suspend it from the desktop. This can improve the ventilation effect at the bottom, reduce interference from obstacles on the ground, expand signal coverage, improve network penetration, and prevent personnel from carelessly forgetting to open the support structure 8. By arranging a plugging member 71 inside the protection mechanism 7, an isolation member 72 is slidably arranged left and right on the plugging member 71. The isolation member 72 is movably connected to the support structure 8. When the support structure 8 moves up and down, the isolation member 72 can swing back and forth left and right, and thus can come into contact with the brush in the plugging member 71. The brush will clean the surface of the filter cloth 722, so that the attached impurities will fall off and flow out through the discharge port 12, avoiding excessive dust accumulation on the isolation member 72 and reducing the heat dissipation effect.
