Abstract

A fastening device is provided with an elastic piece with nose bar connected with a body, and a slot opening in correspondence with the nose bar. A press plate with a concaved hole in correspondence with the elastic piece is pivotally connected with the body. A fastener with pulling piece and hook is also arranged on the body. The body can be fixed on a rack in a computer mainframe casing. After a data accessor like a CD-ROM or a disc drive is assembled to the rack, the press plate can be pressed to push the elastic piece, the nose bar of the elastic piece consequently penetrates out of a hole in the body and inserts into a bolt hole arranged on a casing of the data accessor, thereby, the data accessor can be fixed on the rack. And the press plate can also be pulled open to enable the nose bar to retract from the bolt hole of the data accessor, thereby disassembling the data accessor.

Description

Buckling device

Technical field

The utility model relates to a kind of main case of computer inside that is applied in, and is used for the convenient device that CD-ROM drive or disc driver is fixed in the frame in the main case.

Background technology

General main case of computer inside all needs to assemble disc driver, even CD drive or cd-rom recorder (following general designation data access) also are almost indispensable outfits.Traditionally data access being assembled in the mode of main case of computer inside, is that data access is pushed frame in the main case, locks the screw that the data access shell is reserved again after utilizing screw to pass the hole of frame then; Since assembling need utilize during data access turnscrew with a majority screw closure in frame, therefore assemble comparatively inconvenience.

Summary of the invention

Problem to be solved in the utility model is when traditionally data access such as disc driver or CD-ROM drive being assembled in the frame of main case of computer inside, must utilize instruments such as turnscrew to assemble the inconvenience that a plurality of screw produces.

Major technique means of the present utility model, be that frame in main case of computer inside is provided with buckling device, this buckling device is controlled the medial surface that a nose bar passes frame by the mode of stirring pressing plate, make nose bar penetrate the set screw of data access shell again and data access is fixed on frame, and when oppositely stirring pressing plate, then can make nose bar leave the screw of data access shell, thereby can unload data access.

Compare with prior art, the utility model does not need to use turnscrew or other aid fully when assembling or dismounting data access, do not need to utilize screw to fix yet, and therefore assembling or dismounting are all very convenient.

Embodiment

Embodiment conjunction with figs. of the present utility model is described further and will more can understands.

Consult Fig. 1, Fig. 4 and shown in Figure 5, the preferred implementation that fastening of the present utility model is decided device includes a body 1, two pressing plates 2 and two groups of fastener set 3; Body 1 wherein can be an elongate body, is respectively equipped with a slotted eye that runs through 10 in symmetrical both sides, the bottom surface of body 1, and the shell fragment 11 of a strip is set respectively in the relative both sides of body bottom surface; One end of described shell fragment 11 is fixed in body 1, and makes and form a suitable angle between the bottom surface of shell fragment 11 and body 1, and the other end of shell fragment 11 then has nose bar 111, and makes the slotted eye 10 of nose bar 111 corresponding to body 1; Described shell fragment 11 can be independently individual, is locked in body with screw again, or with the rivet rivet clasp in body, also can adopt ejection forming technique and bulk junction to lump together.

Described pressing plate 2 is strip preferably, central authorities at pressing plate 2 are provided with a fin 21, end near fin 21 is to mold protuberance 211 downwards on one day, and the other end of fin 21 then molds another protuberance 212 and form a shrinkage pool 22 below this protuberance 212; One end of two groups of pressing plates 2 is connected to the relative both sides of base plate of body 1 with pivot shaft, and makes the position of pressing plate 2 corresponding to shell fragment 11, makes pressing plate 2 relatively to rotate with body 1, and makes described protuberance 211 approach the free-ended top of shell fragment 11.

Described fastener set is made up of two fasteners 3, each fastener 3 all is made for the structure with a moving plate 32 and a hook portion 31 to possess flexible plate, and this moving plate 32 links together with hook portion 31 and becomes L shapedly, and hook portion 31 is moved; After two groups of fasteners 3 were combined into a fastener set, two hook portions 31 were positioned at symmetrical position.The utility model is provided with two groups of fastener set on body 1, and makes the position of two hook portions 31 of two groups of fastener set corresponding to the shrinkage pool 22 of institute's pressing plate 2.

By device of the present utility model, when pressing plate 2 when down direction presses (as shown in Figure 2), protuberance 211 is simultaneously to pressing above the shell fragment 11, and then make the nose bar 111 that is located at shell fragment 11 pass the slotted eye 10 (as shown in Figure 3) of body 1, fasten the edge 221 of shrinkage pool 22 both sides up to two hook portions 31 of fastener 3, just can make pressing plate 2 be fastened and up not flick, can guarantee that so nose bar 111 remains on the state that passes slotted eye 10.And when two moving plates 32 of fastener set are stirred toward the directions of leaving relatively, then can make two hook portions 31 relatively close, and then solve buckle, at this moment shrinkage pool 22 relative both sides of the edge 221, see through the elastic force of shell fragment 11 itself, promoted pressing plate 2 and flick (as shown in Figure 4) toward tops.

Fig. 6 and shown in Figure 7 for another example, buckling device 1 of the present utility model is to be assembled in main case inside in advance to specialize in frame 5 outsides that are used for making up data access 4 such as CD-ROM drive or disc driver when the production line of factory, the sidewall of described frame 5 then leaves the perforation (not shown) corresponding to described projection 111 positions in advance, the ad-hoc location of general data access 4 side wall of outer shell is equipped with normalized screw, so that utilize the mode of lock screw that data access is fixed in frame traditionally; And adopt after the buckling device of the present utility model, then as long as after pushing data access 4 in the frame 5, again with aforesaid mode operated clamp 2, the nose bar 111 that is located at shell fragment 11 is penetrated finish in the screw of data access 4 shells fixing, when unloading data access 4, then, just can make nose bar 111 break away from screw with reverse manner operated clamp 2; In the whole operation process, do not need to make turnscrew or other instrument fully, also need not use the screw data access that locks, thereby assembling or dismounting are all very convenient.

The above only is in order to explain the utility model preferred embodiment; be not that the attempt tool is done any pro forma restriction to the utility model; so; all have in that identical utility model spirit is following do relevant any modification of the present utility model or change, all must be included in the category of the utility model intention protection.
