Background Art

[0002] With the current trend of network cloud technology and the Internet of Things, the server technology of computers and industrial computers is growing at a rapid pace. Its development trend is mainly towards strong computing functions, fast speed and small size. In addition, many electronic devices or equipment will use computers to control their actions or execute functions, making computers occupy an extremely important position. When computers and industrial computer servers process huge data calculations, they urgently need high-density and large-scale memory storage devices (such as hard disk drives, solid-state hard disks, optical disk drives or burners, etc.) to store and read data. Therefore, a large number of memory storage devices are generally placed inside computer hosts, server chassis, storage or telecommunications cabinets, etc. to increase storage capacity.

[0003] Furthermore, since a general computer host, server hard disk, storage or telecommunication chassis has a large number of memory storage devices, when the user performs maintenance or replacement operations on each memory storage device, the replacement speed between the memory storage devices installed inside the hard disk must be simpler and faster, and the assembly structure and component manufacturing costs must also be taken into consideration to meet the cost and demand of the large number of memory storage devices. When the hard disk is in operation for a long time, the stability of the overall system and the convenience of maintenance and replacement must be considered, and the user's operation must be convenient, thereby reducing downtime and manpower losses. However, some memory storage devices currently used are fixed in the hard disk by screw locking, and the screws are respectively passed through the through holes on the frame and then aligned and locked into the screw holes of the memory storage device. This screw locking method not only requires the use of a large number of screws, but also requires the removal and installation of multiple screws one by one before disassembly and installation, resulting in a considerable amount of time spent on assembly, resulting in a significant increase in downtime for maintenance. If the hard disk is filled with interface cards, memory storage devices, power wiring, cables and other components, it is very difficult to insert tools to lock or unlock. It is very inconvenient and may even cause the screw to fall off and be lost during locking or unlocking. If the screw is not the right size and is locked with force, it is easy to damage the screw hole on the memory storage device, which is not conducive to assembly or disassembly. In addition, server hard disks are widely used in telecommunications or storage systems and computer rooms of data centers. When a single memory storage device can be repaired and replaced more easily, the number of tens of thousands of memory storage devices installed in the server in the computer room can be greatly increased, and it can be quickly disassembled for repair and replacement, which is an urgent research topic for relevant manufacturers engaged in this industry.

[0059] See also Figure 7 to Figure 10 As shown, it is a plurality of action diagrams of the locking device installed on the movable frame of the present invention being opened, wherein the locking device 1 is locked at the two side plates 21 of the movable frame 2, and the movable frame 2 is located on the two sides of the tray 3 and can be rotated, and the tray 3 is stored in a chassis 4 of a server. When the movable frame 2 is stored on the two sides of the tray 3, the inner wall surface of the chassis 4 presses against the hook portion 121 located on the surface of the cover body 111, and the hook portion 121 is squeezed and deformed, so that the two fixing portions 122 of the pressing adjustment member 12 are outwardly separated from the accommodating groove 1112 The user applies force to the handle 215 on the movable frame 2 to rotate it downward. At this time, the limiting protrusion 212 of the movable frame 2 is located in the positioning groove 41 of the chassis 4 without interfering with other mechanisms, and the hook 143 of the locking device 1 is locked in the positioning frame 42 of the chassis 4, and the abutting edge 145 of the rotary buckle body 14 abuts against the first stopper 1115 of the cover body 111 (such as Figure 7 , Figure 8 As shown); when the movable frame 2 is rotated from the support box 3 to a predetermined angle, the hook portion 121 on the surface of the cover body 111 is not held by the inner wall of the chassis 4, and the hook portion 121 of the press-fit adjustment member 12 is elastically reset to re-accommodate the two fixing portions 122 in the receiving groove 1112, and the two sides of the rotary buckle body 14 are not tightly pressed against the cover body 111 and the back plate 112, and the rotary buckle body 14 is rotated, and the hook 143 of the rotary buckle body 14 is rotated downward (in the process of the movable frame 2 rotating downward, the guide rounded corner 142 of the rotary buckle body 14 contacts the cover body 1 When the first stopper 1115 of the movable frame 21 is engaged and positioned in the positioning frame 42 at the bottom of the chassis 4 to form a fixed state and the movable frame 2 is opened to the maximum angle, at this time, the side plate 21 of the movable frame 2 contacts the stopper 32 of the tray 3 to form an interference stop, and the front end of the limiting protrusion 212 on the bottom side of the side plate 21 abuts against the arc groove 213 and contacts the front end stopper side 411 of the positioning groove 41 of the chassis 4 to form an interference stop, so that the tray 3 can be dragged and moved horizontally outward by a predetermined distance and the top side of the accommodating space 30 is exposed (such as Fig. 9 , Fig.10 As shown), the computer parts installed in the tray 3 are repaired or replaced, and the movable frame 2 can be pushed back to the two sides of the tray 3 after completion.

[0060] See also Fig.11 , Fig.12As described above, it is a plurality of action diagrams of the locking device installed on the movable frame of the present invention for closing. When the movable frame 2 is to be pushed back to the two sides of the tray 3, the user applies force to the handle 215 on the movable frame 2 to rotate it upward. At this time, after the guide inclined portion 144 of the front edge of the rotary button body 14 contacts the contact edge 421 of the positioning frame 42 of the chassis 4, the rotary button body 14 generates an upward sliding force and temporarily separates from the positioning frame 42 of the chassis 4 to form a damping rotation. At the same time, the side plate 21 of the movable frame 2 rotates away from the stop body 32 and is free from interference; the limiting protrusion 212 on the bottom side of the side plate 21 is also away from the front end stop side 411 of the positioning groove 41 and is free from interference (such as Fig.11 As shown in the figure, during the upward rotation of the movable frame 2, the rounded corner 142 of the turn button body 14 contacts the first stop portion 1115 of the cover body 111 to generate a damped rotation, and the abutting edge 145 of the turn button body 14 abuts against the first stop portion 1115 of the cover body 111, so that the turn button body 14 can be positioned in the housing 11 without rotation and the hook 143 is buckled back to the positioning frame 42 of the chassis 4 to form a positioning. At the same time, the movable frame 2 is also pushed back to the two sides of the tray 3, so that the inner wall surface of the chassis 4 is pressed against the hook portion 121 located on the surface of the cover body 111 again, so that the two sides of the turn button body 14 are pressed and tightly attached by the cover body 111 and the back plate 112 without rotation (as shown in the figure). Fig.12 As shown), a mechanism with quick disassembly and assembly is formed by the above.

[0061] Another advantage of the present invention is that the shaft seat 31 of the tray 3 and the pivot 13 of the locking device 1 are not at the same position when rotating, which has the advantages of saving the space required for the rotating mechanism and increasing the distance between the force application point and the pivot 13 of the locking device 1 to form a larger lever ratio so that force can be applied easily.

[0062] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the present invention specification and drawings should be included in the patent scope of the present invention and are hereby stated.
