TWI408533B - Structure for preventing a computer case from being dismantled and a computer case using the same - Google Patents

Abstract

A structure for preventing a computer case from being dismantled includes at least one hook set on an inside of a bezel of the computer case, a lock elastically and slidably mounted to a bracket of the computer case, and a salient set on a side plate of the computer case. The salient is used to push the lock. The lock includes a receiver. When the side plate is fixed onto the bracket of the computer case, the salient pushes the lock to slide on the bracket in order to make the hook hitch the receiver of the lock. When the side plate is removed from the bracket, the lock reversely slide in order to make the hook disengage from the receiver of the lock. Thus the bezel can be removed.

Description

Tamper structure and computer case using the same

The present invention relates to a tamper-evident structure and a computer case using the same, and more particularly to a panel detachment structure and a computer case using the same.

With the popularity of computers, computers play an increasingly important role in people's lives, and the resources within computers are becoming more and more important. Therefore, people have proposed the concept of computer chassis anti-theft. For vertical cabinets, it is usually designed with a detachable structure or lock protection between the rack and its split side panels; for horizontal cabinets, it is usually designed between the rack and its detachable top panel. Demolition structure or lock protection. However, they all neglect to effectively control the panel, so that the panel may be disassembled and the internal resources of the chassis are stolen. This brings hidden dangers to the security of the chassis.

Therefore, it is necessary to provide a tamper-proof structure to eliminate the above-mentioned defects.

In view of the above, it is necessary to provide a tamper-proof structure that can prevent the panel of the computer case from being detached.

The three sliding grooves 53 are horizontally arranged in the same a straight line; a middle portion of the second lock lever 50 protrudes forwardly from the front of the hook 55, and a middle portion of the second lock lever 50 is horizontally opened with a slot 56; the second lock lever 50 is disposed at a lower lateral direction. The square holes 57 and the four square holes 57 are horizontally arranged on the same straight line, and the intervals of the four square holes 57 are the same as the intervals of the four rectangular holes 15 of the joint portion 13 of the chassis 10.

Referring to FIG. 9 to FIG. 12, when assembled, the contact block 33 of the first lock lever 30 is inserted into the slot 66 of the front panel 60 of the chassis 10, and the hooking piece 62 of the front panel 60 is extended into the first. In the square hole 31 of the lock lever 30; the first lock lever 30 is slidably fixed to the first lock lever 30 by the two screws 38 passing through the guide grooves 346 and 366 of the first lock lever 30 and the corresponding screw holes 64 of the front panel 60, respectively. The front plate 60; the two ends of a tension spring 39 are respectively hooked in the holes of the hooking piece 32 of the first lock lever 30 and the holes of the hooking piece 62 of the front plate 60, so that the first lock bar 30 can be Slides relative to the front panel 60 under elastic constraints. The panel 20 is mounted on the front panel of the frame 10, and the hooks 24 of the two protrusions 22 of the panel 20 are respectively inserted into the accommodating cavities 344, 364 of the first lock lever 30, and the two hooks 24 are respectively engaged. The spacer 348 of the accommodating cavity 344 and the spacer 368 of the accommodating cavity 364 are fastened. As shown in FIG. 7 and FIG. 8, the hooks 14 of the joint portion 13 of the top plate 11 of the frame 10 are passed through the slots 56 of the second lock bar 50, so that the three hooks 12 of the top plate 11 of the frame 10 are respectively passed through the second. The corresponding three open slots 54 of the lock lever 50 enter the corresponding sliding slots 53 and let the locking tabs 51 of the second lock lever 50 pass through the strip holes 72 of the rear plate 70 of the frame 11 (see Figures 2 and 3). As shown, and the second lock lever 50 is supported on the plurality of hooks 16 of the engaging portion 13 of the top plate 11, so that the second lock lever 50 is slidable relative to the engaging portion 13 of the top plate 11, and the second lock lever 50 is The projection of the four smaller square holes 57 at the joint portion 13 is always located in the corresponding four large rectangular holes 15 on the joint portion 13, and the two ends of a tension spring 59 are respectively hooked to the second lock. The rod 50 is hooked 55 and the hook 14 of the joint portion 13 of the top plate 11 such that the second lock lever 50 is slidable relative to the joint portion 13 under elastic restraint; the side panel 40 is mounted on the frame 10, and the side panel 40 is The hooks 44 respectively pass through the corresponding rectangular holes 15 of the joint portion 13 of the top plate 11 and the corresponding square holes 57 of the second lock lever 50, and the tabs 42 of the side plates 40 will press the left side of the contact block 33 of the first lock lever 30. surface.

In use, due to the pulling force of the spring 59 connected between the hook 14 of the engaging portion 13 of the frame 10 and the hook 55 of the second lock lever 50, the four hooks 44 passing through the side plates 40 of the corresponding square holes 57 are always Hooking on the side wall of the second lock bar 50, so that the side plate 40 cannot be separated from the frame 10; pushing the locking piece 51 of the second lock lever 50 to make the second lock lever 50 opposite to the joint portion 13 of the frame 10. The front hooks are slid until the four hooks 44 of the side panel 40 are disengaged from the side walls of the second lock lever 50, and the four hooks 44 of the side panel 40 can be correspondingly long from the corresponding square holes 57 of the second lock lever 50 and the joint portion 13 of the frame 10. The square holes 15 are withdrawn so that the side panels 40 can be detached from the frame 10. Similarly, the side plate 40 can be reinstalled on the frame 10, and after the installation, a lock (not shown) can be locked on the locking hole 52 of the locking piece 51 of the second lock lever 50, thereby ensuring that the side plate 40 is not Will be opened by others. When the side panel 40 is mounted to the frame 10, the tab 42 of the side panel 40 will press the contact block 33 of the first lock lever 30 mounted on the front panel 60 of the chassis 10 such that the first lock lever 30 slides toward the front panel 60. On the right side, the hooks 24 of the two protrusions 22 mounted on the panel 20 of the front panel 60 respectively hook the spacers 348 of the corresponding accommodating cavity 344 of the first lock lever 30 and the spacers of the accommodating cavity 364. 368, so that the panel 20 cannot be separated from the frame 10; when the side panel 40 is removed, the tab 42 of the side panel 40 will be disengaged from the contact block 33 of the first lock lever 30, and hooked on the first lock lever 30. Under the pulling force of the spring 39 between the piece 32 and the hooking piece 62 of the front plate 60, the first locking bar 30 will slide to the left side of the front plate 60, thereby disengaging the claws 24 of the two projecting portions 22 on the panel 20. The corresponding spacers 348, 368 of the first lock lever 30 enable the two extensions 22 of the panel 20 to be withdrawn from the corresponding receiving cavities 344, 364 of the first lock lever 30, so that the panel 20 can be removed from the chassis 10. Remove.

According to the above embodiment, only by controlling one lock, the loading and unloading of the side panel 40 and the panel 20 of the computer case can be secured at the same time, thereby reliably protecting the resources in the computer case.
