[0010] According to the above technical solution, the diameter of the rubber guide wheel is larger than the diameter of gear one, and a limit plate is provided at the bottom of the rotating rod one, and the limit plate can be provided to limit the gear two.

[0011] According to the above technical solution, the side of the rotating rod 1 away from the gear 2 is rotatably connected to the inner wall of the protective frame, so as to support the rotating rod 1.

[0012] According to the above technical solution, the rotating rod 2 is rotatably connected to the inner wall of the protective frame at one end away from the ratchet, and the torsion spring is fixedly connected to one side of the fixed frame at one end away from the pawl. The ratchet and the pawl are slidingly locked in cooperation, and the ratchet can be unidirectionally locked by the pawl.

[0013] According to the above technical solution, the number of gear one, gear two, rotating rod one, pulley one, belt, pulley two, rotating rod two, ratchet, protective frame, adjustment door, fixed frame, pawl and torsion spring is two, and the two gears one, gear two, rotating rod one, pulley one, belt, pulley two, rotating rod two, ratchet, protective frame, adjustment door, fixed frame, pawl and torsion spring are symmetrically distributed at the top and bottom of the protective frame. By arranging two ratchets and pawls to cooperate, the locking can be made more stable. A magnetic block one is embedded in the front end of the adjustment door close to the outer wall of the protective frame, and a magnetic block two is arranged at the corresponding position of the protective frame and the adjustment door magnetic block one.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when a U disk needs to be inserted into the USB interface of a computer, the present invention controls the U disk to be inserted into the inside of the protection frame along the guide slot along the front side of the protection frame, and as the U disk moves during insertion, the outer wall of the U disk contacts and rubs against the rubber guide wheel, causing the rubber guide wheel to rotate, and when the rubber guide wheel rotates, the rotating shaft rotates accordingly, and the gear 1 on the rotating shaft rotates synchronously, and when the gear 1 rotates, the gear 1 drives the gear 2 to rotate, and at the same time, the rotating rod 1 in the middle of the gear 2 rotates accordingly, and by providing the rubber guide wheel, the friction force of the U disk can be increased when it moves, and at the same time, the positioning and guiding work can be performed when the U disk is inserted, so as to avoid the U disk interface being damaged due to the crooked insertion of the U disk;

[0015] When the rubber guide wheel rotates, the rotating rod 1 rotates accordingly, and at the same time, the pulley 1 on the rotating rod 1 drives the pulley 2 and the rotating rod 2 to rotate through the belt, further rotating the ratchet on the rotating rod 2. When the ratchet rotates, the outer side of the ratchet cooperates with the pawl. At this time, the ratchet pushes the pawl, compressing the torsion spring. When the torsion spring rebounds, the pawl moves to the next snap-in position on the outer side of the ratchet, so that the ratchet can only rotate in one direction. At the same time, the direction of the rotating rod 2 is restricted to prevent the rotating rod 2 from rotating in the opposite direction, causing the rubber guide wheel to reverse and push the U disk out of the protection frame, thereby preventing the U disk from being stolen artificially during use. When the U disk is extracted, the outer side of the U disk contacts the rubber guide wheel, and the rubber guide wheel cannot rotate in the opposite direction under the cooperation of the ratchet and the pawl, making it more laborious to pull out the U disk, and the time used to steal the U disk is longer. People with less strength cannot even pull the U disk out of the protection frame, so that the device has an anti-theft function.

[0016] When it is necessary to take out the U disk, the adjusting door is pulled to separate the magnetic block 1 on the adjusting door from the magnetic block 2 on the protective frame, and the ratchet is slightly rotated to draw the pawl out of the bayonet on the outer side of the ratchet, and the ratchet can rotate freely, and then the U disk is pulled out from the protective frame, and at the same time, the ratchet drives the fixing frame to rotate in the opposite direction, and the pulley 2 drives the pulley 1 to rotate in the opposite direction through the belt, and the rotating rod 1 in the middle of the pulley 1 rotates in the opposite direction, and the gear 2 drives the gear 1 to rotate, so that the rubber guide wheel in the middle of the gear 1 rotates in the opposite direction, and the U disk can be normally drawn out without affecting the normal use of the U disk. At the same time, the protective frame is set to wrap the U disk in the protective frame to protect the U disk and prevent the U disk from being damaged by impact. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-4 The present invention provides a technical solution: a computer hardware protection device for information security, including a computer case 1, and also including a guide component 6, a transmission component 8 and a locking component 9. A case panel 2 is arranged on the front of the computer case 1, a ventilation and heat dissipation hole 3 is opened at the bottom of the front of the case panel 2, a USB interface 4 is arranged at the top of the front of the case panel 2, a protection frame 5 is fixedly connected to the outside of the USB interface 4 on the front of the case panel 2, and a rotation groove 7 is opened in the middle of the left and right sides of the protection frame 5.

[0028] Wherein, the guide assembly 6 comprises:

[0029] The guide slide groove 601 is arranged in the middle of the top and bottom of the protection frame 5, and the middle part of the rotating groove 7 is rotatably connected with a rotating shaft 602, and the middle part of the rotating shaft 602 is fixedly connected with a rubber guide wheel 603, and the outer side of the rotating shaft 602 is provided with a gear 1 604 on the upper and lower sides of the rubber guide wheel 603, and the outer side of the gear 1 604 is meshed with a gear 2 605, and the middle part of the gear 2 605 is rotatably connected with a rotating rod 1 606.

[0030] The diameter of the rubber guide wheel 603 is greater than the diameter of the gear 1 604 , and a limit plate is provided at the bottom of the rotating rod 1 606 , and the gear 2 605 can be limited by providing the limit plate.

[0031] The side of the rotating rod 1 606 away from the gear 2 605 is rotatably connected to the inner wall of the protection frame 902, so as to support the rotating rod 1 606.

[0032] When it is necessary to insert a U disk into the USB interface of the computer, the U disk is controlled to be inserted into the protective frame 5 along the guide groove 601 along the front side of the protective frame 5. As the U disk moves during insertion, the outer wall of the U disk contacts and rubs the rubber guide wheel 603, so that the rubber guide wheel 603 rotates. When the rubber guide wheel 603 rotates, the rotating shaft 602 rotates accordingly, and the gear 1 604 on the rotating shaft 602 rotates synchronously. When the gear 1 604 rotates, the gear 1 604 drives the gear 2 605 to rotate, and the rotating rod 1 606 in the middle of the gear 2 605 rotates accordingly. By providing the rubber guide wheel 603, the friction force of the U disk can be increased when it moves, and the positioning and guiding work can be performed when the U disk is inserted, so as to avoid the U disk interface being damaged due to the crooked insertion of the U disk.

[0033] See also Figure 4-7 The present invention provides a technical solution: the transmission component 8 includes a pulley 801, a belt 802, a pulley 803 and a rotating rod 804, the pulley 801 is fixedly connected to the outside of the rotating rod 606, the belt 802 is transmission connected to the outside of the pulley 801, the pulley 803 is transmission connected to the end of the belt 802 away from the pulley 801, and the rotating rod 804 is fixedly connected to the middle part of the pulley 803.

[0034] The locking assembly 9 includes a ratchet 901, a protective frame 902, an adjusting door 903, a fixing frame 904, a pawl 905 and a torsion spring 906. The ratchet 901 is fixedly connected to the outer bottom of the rotating rod 804. The protective frame 902 is fixedly connected to the outer side of the protective frame 5 and is located outside the rotating groove 7. The adjusting door 903 is hinged to the outer side of the protective frame 902. The fixing frame 904 is fixedly connected to the side of the adjusting door 903 close to the outer wall of the protective frame 5. The pawl 905 is rotatably connected to the side of the fixing frame 904 close to the ratchet 901. The torsion spring 906 is fixedly connected to the side of the pawl 905 away from the ratchet 901.

[0035] The rotating rod 804 is rotatably connected to the inner wall of the protective frame 902 at the side away from the ratchet 901, and the end of the torsion spring 906 away from the pawl 905 is fixedly connected to the side of the fixing frame 904. The ratchet 901 and the pawl 905 are slidingly locked together, and the ratchet 901 can be unidirectionally locked by the pawl 905.

[0036] There are two gears 1 604, 2 gears 605, 1 rotating rod 606, 1 pulley 801, belt 802, 2 pulley 803, 2 rotating rod 804, ratchet 901, protective frame 902, adjusting door 903, fixed frame 904, pawl 905 and torsion spring 906.

By arranging two ratchets 901 and pawl 905 to cooperate with each other, the locking can be made more stable. A magnetic block 1 is embedded in the front end of the adjusting door 903 close to the outer wall of the protective frame 902, and a magnetic block 2 is arranged at the corresponding position of the protective frame 902 and the magnetic block 1 of the adjusting door 903.

[0037] When the rubber guide wheel 603 rotates, the rotating rod 1 606 rotates accordingly. At the same time, the pulley 1 801 on the rotating rod 1 606 drives the pulley 2 803 and the rotating rod 2 804 to rotate through the belt 802, and further rotates the ratchet 901 on the rotating rod 2 804. When the ratchet 901 rotates, the outer side of the ratchet 901 cooperates with the pawl 905. At this time, the ratchet 901 pushes the pawl 905, so that the torsion spring 906 is compressed. When the torsion spring 906 rebounds, the pawl 905 moves to the next bayonet on the outer side of the ratchet 901, so that the ratchet 901 can only rotate in one direction. At the same time, the direction of the second rotating rod 804 is restricted to prevent the second rotating rod 804 from rotating in the opposite direction, causing the rubber guide wheel 603 to reverse and push the USB flash drive out of the protection frame 5, thereby preventing the USB flash drive from being stolen when in use. When the USB flash drive is extracted, the outer side of the USB flash drive contacts the rubber guide wheel 603, and the rubber guide wheel 603 cannot rotate in the opposite direction under the cooperation of the ratchet wheel 901 and the ratchet claw 905, making it more difficult to pull out the USB flash drive, and the time used to steal the USB flash drive is longer. A person with less strength may not even be able to pull the USB flash drive out of the protection frame 5, so that the device has an anti-theft function.

[0038] When it is necessary to take out the U disk, the adjusting door 903 is pulled to separate the magnetic block 1 on the adjusting door 903 from the magnetic block 2 on the protective frame 902, and the ratchet 901 is slightly rotated to allow the pawl 905 to be pulled out from the bayonet on the outer side of the ratchet 901, and the ratchet 901 can rotate freely, and then the U disk is pulled out from the protective frame 5, and at the same time, the ratchet 901 drives the fixing frame 904 to rotate in the opposite direction, and the pulley 2 803 drives the pulley 1 801 to rotate in the opposite direction through the belt 802, and the rotating rod 1 606 in the middle of the pulley 1 801 rotates in the opposite direction, and at the same time, the gear 2 605 drives the gear 1 604 to rotate, so that the rubber guide wheel 603 in the middle of the gear 1 604 rotates in the opposite direction, and the U disk can be normally pulled out without affecting the normal use of the U disk. At the same time, by setting the protective frame 5, the U disk is wrapped in the protective frame 5 to protect the U disk and prevent the U disk from being damaged by impact.
