The present invention provides a quick release structure for the access device in the chassis, in particular, the holding hole at the two sides of the access device is a rotating shaft that penetrates the two side plates of the elastic positioning member, and is slidably embedded in the chassis by the rotating shaft. The guide rail can be pulled by the elastic positioning member to rotate the positioning portion against the chassis to position the access device at the opening of the docking space.

According to today's computer technology, the computer technology is growing at a rapid rate. The development trend of the computer is mainly toward the powerful computing function, fast speed and small size, so that the number of communication ports of computer-related peripheral devices and recording media machines (such as disk) The number of machines, hard drives, CD players, burners, etc. is also reduced, and the fixing or disassembly of the computer mainframe and the recording media machine contained therein must be simpler and cannot be used too much. The space can be effectively adapted to the trend of shrinking the computer to meet the design requirements of light, thin, short and small.

In addition, in a general server chassis, a storage cabinet or a telecommunication cabinet, there are a large number of recording medium machines (such as a hard disk, a CD player, a burner, etc.), and the user replaces or maintains each recording medium machine. At the same time, the replacement speed between the outer casing and the recording medium machine contained therein must be simpler and faster, and the manufacturing cost of the assembly structure and components must be taken into account, which can meet the huge cost and demand of the recording medium machine.

However, for long-term use of storage cabinets or telecom cabinets, it is necessary to take into account the stability of the overall system and the convenience of maintenance and replacement, and to facilitate the operation of the user to reduce the loss of downtime and manpower, but the current The media storage device used in the storage cabinet or the telecom cabinet is mostly screw-locked. The time required to align the screws one by one and lock into the fixing screw hole is quite long, so that the maintenance time is down. Significantly increased, if the frame of the server chassis is thin and the height between the frames is not high, whether it is a server chassis or a storage or telecommunication cabinet is covered with interface cards, hard disks and power cables, etc. When the hand tool is inserted into the locking action, it is very inconvenient, even if the screw may fall off during the locking, and the screw is lost, and if the screw is not sized and locked, the fixing screw hole of the media storage device is easily damaged. Not conducive to assembly or disassembly.

As shown in the tenth figure, it is an exploded perspective view of the positioning device of the conventional media storage device. The two side panels A1 of the chassis A are respectively provided with a plurality of perforations A11, and the positioning devices are installed on the side panels A1. B, the positioning device B is provided with a strip-shaped slider B1, and a through hole B11 for inserting the screw C into the through hole A11 is disposed at the center of the slider B1, and each slider B1 is A rail groove B2 is formed at the side, and a pressing arm B3 is disposed on the back surface of the rail groove B2. A pin B31 corresponding to the hole A11 is convexly disposed at the inner side of the pressing arm B3 of the positioning device B, and the pressing arm B3 is applied to the pressing arm B3. The outer cover is covered with a slider B4 which slides along the rail groove B2, and can be moved on the slider B4 to be elastically displaced by the pressing arm B3, and is inserted into the medium of the chassis A located between the two side plates A1 by the latch B31. The holding holes D1 of the storage device D are assembled or combined, or the media storage device D can be quickly disassembled to form a separation.

However, when the positioning device B is actually used, the user must first shift to the unlocked state on the slider B4, and laterally insert the media storage device D into the side panel A1 of the chassis A. After positioning, the slider B4 is moved to interlock the pressing arm B3 to lock the media storage device D. The overall operation is complicated and cannot be quickly replaced, and the pressure cannot be clearly seen from the outside of the positioning device B. Whether the latch B31 of the arm B3 has been aligned with the retaining hole D1 of the media storage device D causes an increase in the trouble and inconvenience of the alignment assembly, and the structure tends to be complicated due to the large number of components of the positioning device B, and it is necessary to open more The set of molds and the increase of the assembly process, and the substantial increase in production costs, is also not conducive to modular production, resulting in low production capacity, that is, the direction of the research and improvement that is pending in this industry.

Therefore, the new creators have designed and produced such information based on the problems and deficiencies of the locating devices of the media storage modules, which have been evaluated and considered by various parties, and have been tried and modified through years of research and development experience in this industry. A new type of quick release structure for the access device inside the chassis was born.

When the access device assembled with the elastic positioning member is assembled in the docking space of the chassis, the head protruding from the surface of the side plate of the elastic positioning member can be slidably engaged on the guide rail, and the device to be accessed is pushed in. After the positioning, the elastic positioning member can be rotated at an angle toward the opening of the docking space, and the positioning portion of the elastic positioning member is rotated and abutted against the chassis to block the access device at the opening of the docking space. It is positioned to achieve a stable structure, easy operation, low cost and more practical effect.

The secondary purpose of the present invention is that the guide rail of the chassis is provided with a rail groove inwardly from the opening of the docking space, and the docking space of the frame is provided with a docking portion on the preset circuit board at the other side of the opening. The head of the elastic positioning member rotating shaft can be laterally slidably engaged on the inner wall surface of the rail groove of the guide rail, and after the device to be accessed is pushed into the position, the head of the rotating shaft can be held at the inner side of the rail groove. The connecting surface of the access device is electrically connected to the mating portion of the preset circuit board along the sliding direction of the docking space of the chassis, and the rotating shaft of the elastic positioning member is matched with the guiding rail of the chassis. The guiding and limiting functions ensure the stability and smoothness of the overall insertion and extraction of the access device.

Another purpose of the present invention is that when the access device is positioned in the docking space of the chassis, the elastic positioning member can be pivoted at an angle to the opening direction of the docking space with the retaining hole of the rotating shaft and the access device as the axis. The protruding buckle of the positioning portion is elastically deformed inwardly against the blocking portion at the inner edge of the fastening portion of the joint portion, and the convex buckle is passed over the process of elastic deformation and resetting of the blocking portion, and the buckle can be buckled. The abutting surface adjacent to the positioning portion is rotatably buckled on the folded edge of the blocking portion, and the positioning post on the base at the two sides of the positioning portion is clamped in the corresponding retaining groove on the frame. Once positioned, the elastic positioning member has an appropriate elastic pre-stress to position the access device to block the opening of the docking space in the chassis, thereby effectively preventing the access device from being damaged due to severe shaking caused by external force. Or the plug is out of the docking part of the preset circuit board, and has a stable anti-back and shockproof effect.
