Description

Technical Field

[0001] This invention belongs to the field of chassis protection, specifically relating to a security lock component for computer chassis used in next-generation information networks. Background Technology

[0002] The next-generation information network aims to build a faster, smarter, safer, and more ubiquitous interconnected world. The computer chassis of the next-generation information network serves as the core hardware carrier, storing a large amount of sensitive data and key information. Currently, the chassis protection locks that are widely used are mostly ordinary rotary locks, and the lock tongue is easily broken by violent disassembly.

[0003] Patent publication number CN220419959U relates to a security lock assembly based on a computer chassis, including a tray. Four feet are fixedly connected to the four corners of the bottom of the tray, and four side bends are fixedly connected to the four corners of the top of the tray. An adjustable locking structure is provided at the middle position of both the front and rear ends of the tray. This security lock assembly based on a computer chassis includes a fixing sleeve, a slot, an extension rod, a positioning groove, a pressure plate, and a U-shaped insert. In use, the computer chassis is placed horizontally on the tray. The extension rod is inserted along the fixing sleeve and pressed down until the pressure plate presses down on the top of the chassis. Then, the U-shaped insert is inserted along the slot, passing through the slot and positioning groove. A lock is attached to the annular end of the U-shaped insert to lock and prevent it from slipping out. Multiple positioning grooves can match chassis of various sizes and heights, realizing an easy-to-lock anti-theft function and solving the problem of devices lacking an easy-to-lock anti-theft function.

[0004] In existing technologies, multiple positioning slots can match chassis of various sizes and heights, realizing the function of easy-to-lock anti-theft. This solves the problem that the device does not have the function of easy-to-lock anti-theft. However, if the chassis is illegally and forcibly opened, the internal transmission hole will be exposed, resulting in the illegal theft of internal information. Furthermore, accidental touch during maintenance can block the transmission hole, causing normal data transmission to be interrupted, reducing the efficiency of use and maintenance of the chassis. At the same time, if the key rotation angle is insufficient during manual operation, the lock tongue will not be able to fully form a limit with the limit plate, resulting in the chassis door being loosely locked and shaking. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a security lock assembly for computer chassis used in next-generation information networks, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a security lock assembly for a computer chassis used in next-generation information networks, comprising a chassis, a lock cylinder assembly, an anti-accidental touch assembly, and a positioning assembly. A door is slidably mounted on the rear side of the chassis, and a lock body is fixedly inserted through the front and rear walls of the door. A limit plate is fixedly mounted on the top of the inner wall of the chassis, and a latch is provided on the circumferential surface of the lock body. The lock cylinder assembly includes components, an elastic telescopic rod, a protective frame, a transmission hole, a blocking hole, an elastic telescopic block, a square slot, and a keyhole. The components are disposed within the chassis. At the bottom of the inner wall, the elastic telescopic rod is fixedly installed on the inner wall of the component. The protective frame slides through the rear side of the component. The protective frame is fixedly connected to the free end of the elastic telescopic rod. The transmission hole is opened on the left side of the component. The blocking hole is opened on the left side of the protective frame. The elastic telescopic block is fixedly installed on the left side of the inner wall of the component. The square groove is opened at the bottom of the protective frame. The keyhole is opened on the rear side of the lock body. When the free end of the elastic telescopic block moves upward, it will contact the square groove and limit the protective frame. The protective frame continuously blocks the transmission hole due to the limitation of the free end of the elastic telescopic block.

[0007] According to the above technical solution, the rear side of the protective frame is set as an inclined surface. By setting the rear side of the protective frame as an inclined surface, the frictional force when the protective frame contacts the locking tongue can be reduced. The protective frame abuts against the locking tongue, and the free end of the elastic telescopic block contacts the bottom of the protective frame.

[0008] According to the above technical solution, the limiting plate is used to limit the lock tongue and the lock body. The lock body is equipped with a spring, which can support the lock body. The protective frame is used to block the transmission hole. When the key matching the lock body is inserted into the keyhole and rotated counterclockwise by 90 degrees, the counterclockwise rotation of the key will drive the lock tongue to rotate counterclockwise. The counterclockwise rotation of the lock tongue will disengage from the limiting plate and release the limitation on the door.

[0009] According to the above technical solution, it also includes an anti-accidental touch component and a positioning component. The anti-accidental touch component is used to prevent accidental touch from blocking the transmission hole. The positioning component is used to prevent insufficient rotation angle of the locking tongue from causing the door to not be locked. The anti-accidental touch component includes a rack block, a mounting frame, a gear, a rack plate, and a protective groove. The rack block is fixedly installed on the left side of the door. The mounting frame is fixedly installed on the inner wall of the box. The gear is rotatably installed on the top of the mounting frame. The rack plate is slidably installed on the top of the mounting frame. The protective groove is opened on the left side of the protective frame. The rack plate is squeezed to the right by the gear and moves to the right. When the rack plate moves to the right, it will contact the protective groove and limit the protective frame. The protective frame cannot move forward due to the limitation of the rack plate.

[0010] According to the above technical solution, a torsion spring is provided between the gear and the mounting frame. The torsion spring can drive the gear to reset. The rack plate meshes with the gear, and the rack block meshes with the gear. When the rack plate moves to the left to reset, it will disengage from the protective groove and release the limit on the protective frame.

[0011] According to the above technical solution, the positioning component includes a stop frame, an elastic telescopic frame, a stop groove, a load-bearing frame, a fastening frame, a fastening spring, and a connecting frame. The stop frame is fixedly installed on the front side of the door, the elastic telescopic frame is fixedly installed on the right side of the stop frame, the stop groove is formed on the circumferential surface of the lock tongue, the load-bearing frame is fixedly installed on the inner wall of the door, the fastening frame is slidably installed on the inner wall of the load-bearing frame, the fastening spring is disposed between the fastening frame and the door, and the connecting frame is fixedly installed on the inner wall of the door. When the lock tongue is rotated clockwise to reset, the stop groove will align with the elastic telescopic frame. After the free end of the elastic telescopic frame aligns with the stop groove, the free end of the elastic telescopic frame moves to the right under its own elastic force to restore contact with the stop groove.

[0012] According to the above technical solution, the fastening bracket abuts against the locking tongue, and the right side of the free end of the elastic telescopic bracket is set as an inclined surface. By setting the right side of the free end of the elastic telescopic bracket as an inclined surface, the frictional force when the free end of the elastic telescopic bracket contacts the locking tongue can be reduced. The free end of the elastic telescopic bracket contacts the stop groove, and the fastening bracket moves to the left under the elastic force of the fastening spring. The fastening bracket moves to the left and thus loosens the power cord.

[0013] According to the above technical solution, the fastening frame and the connecting frame are used to fix the power cord, the elastic telescopic frame is used to position the lock tongue, the fastening frame is in contact with the connecting frame, after the box door moves to the right to seal the box, the lock tongue will contact the arc surface of the fastening frame and squeeze the fastening frame when it rotates clockwise.

[0014] This invention provides a security lock assembly for computer chassis used in next-generation information networks. It offers the following advantages: 1. In this invention, the locking tongue rotates counterclockwise to disengage from the limiting plate and release the restriction on the cabinet door. By installing a rotating locking tongue on the cabinet, the cabinet door can be locked to prevent unauthorized personnel from opening the door at will, thereby improving the physical protection capability of the cabinet. The free end of the elastic telescopic block moves upward to contact the square groove and limit the protective frame. The protective frame continuously blocks the transmission hole due to the limitation of the free end of the elastic telescopic block. When the cabinet is violently dismantled and the locking tongue breaks, the remaining lock tongue will drive the protective frame to move, causing the elastic telescopic block to be stuck in the square groove, thereby forcibly blocking the transmission hole and instantly cutting off the data transmission path, preventing the internal information of the components from being illegally stolen.

[0015] 2. In this invention, when the rack plate moves to the right, it will contact the protective groove and limit the protective frame. The protective frame cannot move forward due to the limitation of the rack plate. The linkage between the rack block, gear and rack plate automatically limits the protective frame, which can avoid accidental human touch during maintenance that could cause the protective frame to block the transmission hole, thereby ensuring normal communication and data transmission of components.

[0016] 3. In this invention, the free end of the elastic telescopic frame moves to the right under its own elastic force to restore contact with the stop groove, thereby locking in place and providing clear positioning feedback. Through the cooperation of the locking tongue and the elastic telescopic frame, it can automatically lock in place and provide clear locking tactile feedback, thereby avoiding false locking and ensuring that the door is firmly sealed.

[0017] 4. In this invention, the fastening bracket moves to the left to loosen the power cord, preventing the power cord from being pulled when moving components or the enclosure during maintenance. The simultaneous loosening of the power cord when unlocking can prevent the power cord from being pulled when moving equipment during maintenance. When locking, the power cord is automatically fixed, which can prevent the cable from becoming loose and ensure stable power supply to the enclosure. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 - Figure 8 One embodiment of the present invention is: a security lock assembly for a computer chassis used in next-generation information networks, comprising a chassis 1 and a lock cylinder assembly. A door 2 is slidably installed on the rear side of the chassis 1, and a lock body 3 is fixedly inserted through the front and rear walls of the door 2. A limit plate 4 is fixedly installed on the top of the inner wall of the chassis 1, and a latch 5 is provided on the circumferential surface of the lock body 3. The lock cylinder assembly includes components 6, an elastic telescopic rod 7, a protective frame 8, a transmission hole 9, a blocking hole 91, an elastic telescopic block 10, a square groove 11, and a keyhole 12. Component 6 is disposed at the bottom of the inner wall of the chassis 1, the elastic telescopic rod 7 is fixedly installed on the inner wall of component 6, the protective frame 8 slidably penetrates the rear side of component 6, and the protective frame 8 is fixedly connected to the free end of the elastic telescopic rod 7. The transmission hole 9 is opened on the left side of component 6. On the side, the blocking hole 91 is opened on the left side of the protective frame 8, the elastic telescopic block 10 is fixedly installed on the left side of the inner wall of the component 6, the square groove 11 is opened at the bottom of the protective frame 8, and the keyhole 12 is opened on the rear side of the lock body 3. When the box body 1 is violently dismantled and the lock tongue 5 breaks, the lock tongue 5 fragment will drive the protective frame 8 to move, so that the elastic telescopic block 10 is stuck into the square groove 11 for a limit, thereby forcibly blocking the transmission hole 9 and instantly cutting off the data transmission path, preventing the internal information of the component 6 from being illegally stolen. The protective frame 8 moves forward to block the transmission hole 9, and the protective frame 8 moves backward to open the transmission hole 9. Once the elastic telescopic block 10 is stuck into the square groove 11, the limit cannot be released from the side of the box door 2, and the internal component 6 must be disassembled, thereby improving the anti-hacking capability.

[0022] The rear side of the protective frame 8 is set as an inclined surface. By setting the rear side of the protective frame 8 as an inclined surface, the frictional force when the protective frame 8 contacts the locking tongue 5 can be reduced. The protective frame 8 and the locking tongue 5 abut against each other, and the free end of the elastic telescopic block 10 contacts the bottom of the protective frame 8.

[0023] The limiting plate 4 is used to limit the lock tongue 5 and the lock body 3. The lock body 3 is equipped with a spring, which is used to drive the lock tongue 5 to automatically reset and assist the lock tongue 5 in returning to its original position. The protective frame 8 is used to block the transmission hole 9. When the key matching the lock body 3 is inserted into the keyhole 12 and rotated 90 degrees counterclockwise, the counterclockwise rotation of the key will drive the lock tongue 5 to rotate counterclockwise. The counterclockwise rotation of the lock tongue 5 will disengage from the limiting plate 4 and release the limitation on the box door 2. By installing a rotary lock (composed of lock body 3, lock tongue 5 and keyhole 12) on the box body 1, the rotary lock can lock the box door 2 to prevent unauthorized personnel from opening the box door 2 at will, thereby improving the physical protection capability of the box body 1.

[0024] In this embodiment, when the cabinet door 2 needs to be opened, the key matching the lock body 3 is inserted into the keyhole 12 and rotated counterclockwise by 90 degrees. The counterclockwise rotation of the key will cause the latch 5 to rotate counterclockwise. The counterclockwise rotation of the latch 5 will disengage from the limiting plate 4 and release the limiting of the cabinet door 2. After the limiting of the cabinet door 2 is released, pushing the cabinet door 2 to the left will release the seal on the cabinet body 1. If the cabinet body 1 is forcibly dismantled and the cabinet door 2 is pushed to the left, the cabinet door 2 will be forcibly pushed to the left, which will cause the lock body 3 to move to the left. The lock body 3 moving to the left will cause the latch 5 to move to the left. The latch 5 moving to the left will contact the inclined surface of the protective frame 8 and squeeze the protective frame 8. The protective frame 8 will move forward under the squeezing of the latch 5. The forward movement of the protective frame 8 will cause the free end of the elastic telescopic rod 7 to move forward and store force. At the same time, the forward movement of the protective frame 8 will align the square groove 11 with the elastic telescopic block 10. After the elastic telescopic block 10 is aligned with the square groove 11, the free end of the elastic telescopic block 10 moves upward under its own elastic force. The upward movement of the free end of the elastic telescopic block 10 will contact the square groove 11 and limit the protective frame 8. The protective frame 8 is continuously blocked by the limit of the free end of the elastic telescopic block 10, so that when the box 1 is forcibly disassembled, the data reading and transmission function of the transmission hole 9 can be cut off instantly, preventing the internal information from being illegally stolen. In addition, to remove the obstruction of the transmission hole 9 by the protective frame 8, the component 6 needs to be disassembled. After the component 6 is disassembled, the free end of the elastic telescopic block 10 can be manually pushed downward and separated from the contact with the square groove 11. After the free end of the elastic telescopic block 10 is separated from the contact with the square groove 11, the protective frame 8 moves backward under the elastic force of the elastic telescopic rod 7. The backward movement of the protective frame 8 can make the transmission hole 9 aligned with the blocking hole 91 and remove the obstruction of the transmission hole 9.

[0025] Please see Figure 1 - Figure 8 Based on the above embodiments, another embodiment of the present invention further includes an anti-accidental touch component and a positioning component. The anti-accidental touch component is used to prevent accidental touch from blocking the transmission hole 9, and the positioning component is used to prevent insufficient rotation angle from causing the door 2 to not be locked. The anti-accidental touch component includes a rack block 131, a mounting frame 132, a gear 133, a rack plate 134, and a protective groove 135. The rack block 131 is fixedly installed on the left side of the door 2, the mounting frame 132 is fixedly installed on the inner wall of the housing 1, the gear 133 is rotatably installed on the top of the mounting frame 132, the rack plate 134 is slidably installed on the top of the mounting frame 132, and the protective groove 135 is opened on the left side of the protective frame 8. The linkage of the rack block 131, the gear 133, and the rack plate 134 automatically limits the protective frame 8, which can prevent accidental touch during maintenance from triggering the protective frame 8 to block the transmission hole 9, thereby ensuring normal communication and data transmission of the components 6.

[0026] A torsion spring is provided between gear 133 and mounting frame 132. The torsion spring can drive gear 133 to reset. Rack plate 134 meshes with gear 133, and rack block 131 meshes with gear 133. When rack plate 134 moves to the left to reset, it will disengage from the protective groove 135 and release the limit on the protective frame 8. Before the box door 2 is completely closed, the protective frame 8 is always limited and cannot trigger protection.

[0027] The positioning assembly includes a stop frame 141, an elastic telescopic frame 143, a stop groove 144, a load-bearing frame 145, a fastening frame 146, a fastening spring 147, and a connecting frame 148. The stop frame 141 is fixedly installed on the front side of the door 2, the elastic telescopic frame 143 is fixedly installed on the right side of the stop frame 141, the stop groove 144 is opened on the circumferential surface of the latch 5, the load-bearing frame 145 is fixedly installed on the inner wall of the box body 1, the fastening frame 146 is slidably installed on the inner wall of the load-bearing frame 145, the fastening spring 147 is located between the fastening frame 146 and the box body 1, and the connecting frame 148 is fixedly installed on the inner wall of the door 2. Through the cooperation of the latch 5 and the elastic telescopic frame 143, they can automatically engage and position themselves, and provide clear tactile feedback of locking, thereby avoiding false locking and ensuring that the door 2 is firmly sealed.

[0028] The fastening bracket 146 abuts against the locking tongue 5. The right side of the free end of the elastic telescopic bracket 143 is set as an inclined surface. By setting the right side of the free end of the elastic telescopic bracket 143 as an inclined surface, the frictional force when the free end of the elastic telescopic bracket 143 contacts the locking tongue 5 can be reduced. The free end of the elastic telescopic bracket 143 contacts the stop groove 144. The fastening bracket 146 moves to the left under the elastic force of the fastening spring 147. The fastening bracket 146 moves to the left and thus loosens the power cord. The power cord is loosened at the same time when unlocking to prevent the power cord from being pulled when repairing the mobile equipment.

[0029] The fastening bracket 146 and the connecting frame 148 are used to fix the power cord, and the elastic telescopic bracket 143 is used to position the locking tongue 5. The fastening bracket 146 contacts the connecting frame 148. After the door 2 moves to the right to seal the box 1, the locking tongue 5 will contact the arc surface of the fastening bracket 146 and squeeze the fastening bracket 146 when it rotates clockwise. When the lock is closed, it automatically restores the fixation of the power cord, which can prevent the cable from loosening and ensure the stable power supply of the box 1.

[0030] In this embodiment, during operation: when the door 2 unlocks normally and moves to the left, it drives the rack block 131 to move to the left. The rack block 131, moving to the left, contacts the gear 133 and presses against it. The gear 133, pressed by the rack block 131, rotates counterclockwise. This counterclockwise rotation of the gear 133 presses against the rack plate 134. The rack plate 134, pressed by the gear 133, moves to the right. The rack plate 134, moving to the right, contacts the protective groove 135 and limits the movement of the protective frame 8, preventing... The protective frame 8 is limited by the rack plate 134 and cannot move forward, thus preventing accidental human contact during the maintenance of the housing 1, which would block the transmission hole 9. When the housing door 2 moves to the right to reset, the movement of the housing door 2 to the right will drive the gear 133 to rotate clockwise. The clockwise rotation of the gear 133 will squeeze the rack plate 134. The rack plate 134, squeezed by the gear 133, moves to the left to reset. The movement of the rack plate 134 to the left will disengage from the protective groove 135 and release the limitation on the protective frame 8.

[0031] When the locking tongue 5 rotates counterclockwise, it presses against the inclined surface of the free end of the elastic telescopic frame 143. The inclined surface of the elastic telescopic frame 143 moves to the left and accumulates force under the pressure of the locking tongue 5. Simultaneously, the free end of the elastic telescopic frame 143 disengages from the stop groove 144 and continues to contact the locking tongue 5. When the locking tongue 5 rotates clockwise to reset, the stop groove 144 aligns with the elastic telescopic frame 143. After the free end of the elastic telescopic frame 143 aligns with the stop groove 144, the free end of the elastic telescopic frame 143 moves to the right under its own elastic force to restore contact with the stop groove 144, thus achieving a clear locking feedback and preventing loosening of the door 2 due to a false lock. Furthermore, the rotation of the locking tongue 5 disengages from the left side of the fastening frame 146 and releases it. The compression of the fastening bracket 146 causes the locking tongue 5 to release its pressure on the fastening bracket 146. Under the elastic force of the fastening spring 147, the fastening bracket 146 moves to the left, thereby loosening the power cord and preventing the power cord from being pulled when moving components 6 or the enclosure 1 during maintenance. After the enclosure door 2 moves to the right and seals the enclosure 1, the locking tongue 5 rotates clockwise and contacts the arc surface of the fastening bracket 146, compressing the fastening bracket 146. The fastening bracket 146 is compressed to the right by the locking tongue 5 and compresses the fastening spring 147. The fastening spring 147 deforms and stores force under the compression of the fastening bracket 146. At the same time, the fastening bracket 146 moves to the right and, together with the connecting frame 148, restores the fixation of the power cord.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
