Turnover bogey

Technical field

The present invention relates to a kind of turnover bogey, particularly relate to a kind of being applied in the computer chassis to locate the bogey of peripheral device.

Background technology

Because computer has become one of instrument of suitable widespread usage in the daily life, therefore for also having on the exterior design of general desktop computer main frame towards the volume densification, compact trend, make that the shared space of computer is dwindled, yet the casing of host computer is interior except motherboard, also include power supply unit, the interface card of various extended functions, and as Winchester disk drive, floppy or CD drive or the like is in order to peripheral device of access data or the like, after so in a single day various devices are fixed with the configuration assembling of suitable densification, though can reach the purpose of reduced volume, yet must change some electronic component to keep in repair for fault in the future, or because of expanding usefulness when installing situations such as extra memory or interface card additional and taking place, original computer chassis is inner because the result of various device densification configurations makes that the space without any affluence exists in the dismounting of electronic installation, therefore can only earlier various peripheral devices be disassembled on casing from outside to inside one by one, after making that computer motherboard reveals, make and to carry out maintain and replace or to install action such as additional electronic component additional, treat again the peripheral device that disassembles to be reinstalled in the computer chassis with reversed sequence after operation is finished, well imagine, this kind process will cause maintenance go up or the user voluntarily during extended function quite inconvenient situation take place.

As Fig. 1 and Fig. 2, in order to solve this problem, applicant Ceng Yidi No. 89202992 " convertible fixedly modules " has applied for patent, after checking and approving, announce and obtain patent right with No. 407847, this patent case mainly is to be applied on the computer chassis of a flat placed type, make computer chassis be provided with a convertible fixed mount 100, the lower end of convertible fixed mount 100 is provided with a fixed mount rotating shaft 104 with in the rotating shaft mating holes 108 that is assembled in correspondence set on the casing lower cover 102, make convertible fixed mount 100 articulate the activity pattern that rotates thus relative to forming with casing lower cover 102, thus, convertible fixed mount 100 can be in order to fixing as peripheral devices such as CD-ROM drive or floppy drives, make assembling back single-piece frame still can form quite intensive configuration kenel to keep the small and exquisite design of volume, and maybe need expand when adding electronic components when keeping in repair, only need motherboard is revealed fixed mount 100 outside upsets, conveniently keep in repair or add the operation of electronic components, and avoid the complicated procedures of repetition dismounting peripheral device, increase considerably convenience and practicality in the use.
