Technical Field
[0001] The present application relates to the technical field of locks, and in particular to a locking device for a chassis. Background Art
[0002] With the rapid development of information technology, computers and related equipment are increasingly used in various fields. As an important component of the computer, the chassis contains a large number of precision components, such as the motherboard, hard disk, power supply, etc. Therefore, ensuring the enclosure and security of the chassis is of great significance to protect the equipment from external interference and damage.
[0003] In response to the aforementioned related technologies, the inventors believe that traditional chassis locking devices mostly use simple padlocks or screws. While these methods can prevent unauthorized access to a certain extent, they are inconvenient to operate, prone to damage, and lack security. For example, padlocks require additional locks and are easily pried open; screw fastenings require tools for assembly and disassembly, which is cumbersome and prone to screw loss. Therefore, the inventors proposed a chassis locking device to address these issues. Utility Model Content

[0021] The following is combined with Figure 1-6 This application is described in further detail.
[0022] The embodiment of the present application discloses a locking device for a chassis. Figure 1-6 A locking device for a chassis includes a chassis 1 and a chassis cover 2. A lock box 6 is fixedly connected to the inner wall of the chassis 1, and a back plate 7 is fixedly connected to the outer wall of the lock box 6. A locking block 5 is fixedly connected to the outer wall of the chassis cover 2 facing the inner cavity of the chassis 1. The locking block 5 corresponds to the lock box 6, and a lock hole is opened on the outer wall. A locking mechanism is installed inside the lock box 6.
[0023] The locking mechanism includes a worm 11 and a worm wheel 12, which are meshed with each other. A gear 13 is fixedly connected to the outer wall of the worm wheel 12. The worm wheel 12 and the gear 13 are rotatably connected to the inner wall of the lock box 6 opposite to the back plate 7 through a rotating shaft. The locking mechanism also includes a rack 15 and a lock core 18, which are meshed with the gear 13. The lock core 18 is fixedly connected to one end of the rack 15, and the end of the lock core 18 away from the rack 15 corresponds to the lock hole and is adapted to be plugged in.
[0024] A self-locking motor 9 is fixedly installed on the inner wall of the lock box 6 through a fixing frame 8. The end of the output shaft of the self-locking motor 9 passes through the fixing frame 8 and is fixedly connected to one end of the worm 11 through a coupling 10. The self-locking motor 9 is connected to an external power supply through a connecting line. A wireless receiver and a motor controller are built into the self-locking motor 9 (not shown in the figure). The user sends control instructions through the buttons on the remote control. The receiver receives the signal from the remote control and converts it into an electrical signal. The motor controller controls the operating state of the self-locking motor 9 according to the received electrical signal.
[0025] Two limit grooves 3 are provided on the inner wall of the box body 1, and the upper and lower outer walls of the box cover 2 are fixedly connected to the limit blocks 4, which are adapted to be plugged into the limit grooves 3. When the box cover 2 drives the two limit blocks 4 to be plugged into the two limit grooves 3, the box cover 2 will be limited by the limit grooves 3, and the box cover 2 can only slide along the length direction of the box body 1 and cannot move along the width direction of the box body 1.
[0026] Reference Figure 5 The rack 15 is slidably connected to the outer wall of the back plate 7 through two brackets 14. A slide groove 16 is provided on the outer wall of the rack 15. The inner wall of the lock box 6 opposite to the back plate 7 is fixedly connected to a limit rod 17. The limit rod 17 is slidably connected to the inner wall of the slide groove 16. The two brackets 14 support and limit the bottom of the rack 15. When the rack 15 moves to the right, its left end is disengaged from the left bracket 14. At this time, the rack 15 drives the slide groove 16 to move to the right, and the limit rod 17 slides to the left on the inner wall of the slide groove 16, thereby supporting and limiting the left end of the rack 15, so that the rack 15 always moves linearly and smoothly.
[0027] The implementation principle of the locking device of a case in the embodiment of the present application is as follows: when in use, the initial state of the lock core 18 is to be retracted into the lock box 6, and the two limit blocks 4 on the case cover 2 are aligned with the limit slots 3 and inserted until the end of the case cover 2 contacts the inner wall of the case body 1. At this time, the locking block 5 corresponds to the lock box 6, and the lock hole corresponds to the lock core 18. At this time, the user sends a control command through the button on the remote control, the receiver receives the signal from the remote control and converts it into an electrical signal, and the motor controller controls the operation state of the self-locking motor 9 according to the received electrical signal;
[0028] When the self-locking motor 9 is started, its output shaft drives the worm 11 to rotate through the coupling 10, and the worm 11 drives the worm wheel 12 engaged with it to rotate, and the worm wheel 12 synchronously drives the gear 13 to rotate, and the gear 13 drives the rack 15 engaged with it to move. Figure 5 When the rack 15 moves to the right, the lock cylinder 18 is pushed out of the lock box 6, so that the lock cylinder 18 is plugged into the keyhole and the box cover 2 is locked. Figure 1 , the box cover 2 cannot slide to the right along the length direction of the box body 1, nor can it move forward or backward along the width direction of the box body 1, completing the locking operation;
[0029] When unlocking, the user controls the self-locking motor 9 to rotate in the opposite direction. Similarly, when the rack 15 is driven to move to the left by the locking mechanism, the lock cylinder 18 is retracted into the lock box 6, so that the lock cylinder 18 is disengaged from the lock hole, thereby releasing the lock on the box cover 2. The box cover 2 can be slid to the right along the length direction of the box body 1 to be removed;
[0030] It is worth noting that the meshing transmission between the worm 11 and the worm wheel 12 in the locking mechanism is self-locking. The self-locking force of the self-locking motor 9 enables the lock core 18 to be firmly fixed when plugged into the lock hole, ensuring its locking force and effectively preventing unauthorized access.
