Description

Technical Field

[0001] This utility model relates to an improved lock structure, and more particularly to a lock structure that is easy to assemble and disassemble. It consists of a cloud-shaped washer assembled between the positioning seat and the rotating body of the lock, which, together with the rotating buckle at the bottom of the positioning seat and the drive shaft at the rotating body, forms a lock with elastic locking operation, thereby facilitating the assembly or disassembly of the lock. Background Technology

[0002] With the current trends of cloud computing and the Internet of Things, the technology of computer and industrial computer servers is growing at a rapid pace. The main development trend is towards powerful computing capabilities, high speed, and small size. Many electronic devices or equipment use computers to control their actions or perform functions, making computers play a very important role. Because computer and industrial computer servers urgently need high-density and large-scale multimedia devices (such as hard drives, optical drives, or CD burners) to store and retrieve data when processing massive amounts of data, a large number of recording media devices are placed inside computer mainframes, server chassis, storage or telecommunications cabinets to increase storage capacity.

[0003] Furthermore, since computer mainframes, server chassis, storage units, and telecommunications cabinets typically house numerous multimedia components, the replacement of these components must be quick and easy when users need to maintain or replace them. Over long-term use, the chassis must also consider overall system stability, ease of repair and replacement, and user convenience to minimize downtime and manpower losses. However, some currently used multimedia components are secured within the chassis using screws. After passing screws through the holes on the frame, they are aligned and tightened into the screw holes of the recording media machine. This screw-locking method not only requires a large number of screws, but also requires disassembling and assembling multiple screws one by one before disassembly and installation. If the inside of the chassis is full of interface cards, recording media machines, power cables, ribbon cables and other components, it will be very inconvenient to insert tools to lock them in, and may even cause the screws to fall off and be lost during the locking process. In addition, if the screws are not the right size and force is applied when locking them, the screw holes on the multimedia mechanism can be easily damaged, which will be detrimental to assembly or disassembly.

[0004] Currently, various mechanisms used in electronic enclosures, telecommunications enclosures, server enclosures, and multimedia systems employ lever-type handles for easy dragging, replacement, and fixing. These handles typically include a safety lock, which is fixed to the handle and uses a single type of operating part (such as a slotted, Phillips, square, hexagonal, or polygonal hole) for operation and control with a specific type of hand tool. When the lock malfunctions or is damaged, the entire handle and lock assembly must be replaced, which is time-consuming, labor-intensive, and increases costs, making it uneconomical. This is precisely the direction that manufacturers in this industry are eager to research and improve. Utility Model Content

[0032] The lock 23 of this utility model is designed to be assembled with the locking mechanism 2 and the base 1. In practical application and implementation, the base 1 can be assembled onto a pre-designed enclosure (such as an electronic enclosure, telecommunications enclosure, server enclosure, or multimedia device, etc.) (not shown in the figure). The base 1 can be fixed to the pre-designed enclosure by means of screws, welding, or adhesive. It serves as a switch handle for the pre-designed enclosure. The drive part 2335 of the lock 23 of the locking mechanism 2 on the base 1 can be opened using a corresponding pre-designed hand tool (such as a key, Phillips screwdriver, etc.). Using a flathead screwdriver, L-shaped wrench, open-end wrench, socket wrench, or other hand tools, the operating drive unit 2335 and the connecting rod 2331 of the interlocking device 23 drive the rotating buckle body 2342 to rotate against the locking hole 2120 on the seat plate 212 of the limiting seat body 21. This applies force to the lifting side 2221 of the lever 222 on one side of the cover body 22, so that the two rotating shafts 223 on the other side of the lever 222 are centered at the two rotating shaft holes 110 on the base 1, and force is applied to the lifting side 2221 to rotate and lift the cover body 22 outward from the base 1. The cover 22 can be used as a handle for the pre-installed enclosure to move and slide, allowing it to be pulled out or pushed into the pre-installed cabinet (such as an electronic cabinet, telecommunications cabinet, server cabinet, multimedia cabinet, computer host, or industrial computer host). After the pre-installed enclosure is assembled in the pre-installed cabinet, the cover 22 can be rotated at the two pivot holes 110 of the pivot part 11 of the base 1 via two pivots 223, so that the cover 22 covers the receiving space 10 of the base 1. The lock on the cover 22 can then be used to... The latch 23 is inserted into the lock hole 2120 of the seat plate 212 of the limiting seat 21 by the latching part 2342. The driving part 2335 on the latch 23 can be operated by the preset hand tool to drive the rotating buckle 234 to rotate through the connecting rod 2331. The driving latch 2342 rotates and interlocks with the lock hole 2120 in a staggered manner to lock it in a locked state. This allows the cover 22 to be limited at the limiting seat 21 and positioned in the accommodating space 10 of the base 1, so as to achieve the purpose of operating the latch 23 to move the cover 22 on the base 1 to flip and cover it.
