Description

Computer casing

The utility model is about a kind of computer casing, is meant especially a kind ofly to have the particular card buckle structure and make the computer casing that the loam cake easy accessibility is laborsaving and buckle is firm.

The tradition manufacturer computer adopts manual mode by screw loam cake to be locked on pedestal in assembling computer casing process.The built-up time of standing is long but this manual locking screw mode often causes single assembling worker, and then makes assembly line long or reduce the assembling speed of production, even production line is paralysed.

For addressing this problem, industry is now changed into the loam cake both side edges several L shaped grabs is set respectively, and offers several in pedestal biside plate apical margin correspondence and accommodate the groove that grab slides therein.Installing only needs the grab of loam cake is aimed at and passed the groove of pedestal during loam cake, and level promotes loam cake and grab slided fasten until grab and base side boards apical margin in the groove of base side boards then, thereby loam cake promptly is installed on the pedestal.Yet when engaging power hour between grab and the side plate apical margin, thereby grab makes loam cake withdraw from from pedestal with the disengaging of side plate apical margin easily.Otherwise the operator needs both hands to apply big horizontal thrust so that loam cake is skidded off along the base side boards apical margin when the dismounting loam cake, makes effort of unloading process.

The purpose of this utility model is to provide a kind of and has the particular card buckle structure and make the computer casing that the loam cake easy accessibility is laborsaving and buckle is firm.

The technical solution of the utility model is achieved in that the utility model computer casing comprises a pedestal, a loam cake and a bayonet unit.Wherein pedestal has a base plate and biside plate, and installing one magnet stand in it.The magnet stand roof is provided with a listrium, and offers at least one chute on the listrium.Loam cake can be installed on the pedestal, offers a slotted hole on it.Bayonet unit can be installed in and cover, and is to be made of a sliding part, a pothook and a spring.Sliding part slidably is installed in and covers, and its bottom surface is provided with a protuberance that can slide and wear in the loam cake slotted hole.Pothook can be installed in the loam cake bottom surface, and is fixed together with sliding part, and at least one chute that wears the magnet stand listrium and barb that engages with the magnet stand listrium of can sliding is set on it, and the free end of barb is provided with first hypotenuse and second hypotenuse.Spring one end and sliding part are fixed, and the other end and pothook are fixed.

The utility model therewith prior art relatively, its advantage is: the buckle between the listrium of the barb of the utility model by the loam cake bayonet unit and pedestal magnet stand concerns makes this case have the advantages that the loam cake easy accessibility is laborsaving and buckle is firm.

With reference to the accompanying drawings, in conjunction with the embodiments the utility model is further described.

See also Fig. 1, the utility model computer casing comprises that a pedestal 20, a loam cake 40 and are installed in the bayonet unit 50 that covers.Wherein pedestal 20 is the open frames that are made of a base plate 22 and biside plate 24, and the magnet stand 30 that is fixed together at pedestal 20 1 sides installing one and base plate 22.Each side plate 24 apical margin extends a flap 25 towards pedestal 20 inner space level bendings, and offers several elongated slots 29 on each flap 25.See also Fig. 4 and Fig. 5, magnet stand 30 roof medial margins bend vertically downward and extend a listrium 36.Listrium 36 is offered three chutes 38 along its length, and listrium 36 is provided with first inclined-plane 39 and second inclined-plane 37 respectively at the both ends of each chute 38.

Loam cake 40 is one to be foursquare plate body substantially, and the elongated slot 29 of corresponding pedestal 20 side plates 24 of its both side edges is provided with several and can card be located at L shaped folding hook 45 in the elongated slot 29, thereby loam cake 40 can be installed on the pedestal 20.The end face of loam cake 40 middle part dashes downwards to establish and forms a microscler depression 44, and dashes in depression 44 bottoms and to establish a slotted hole 46, forms a continuous flanging 47 downwards along slotted hole 46 peripheries.44 bottoms of caving in are parallel to slotted hole 46 1 sides and offer a pair of slide opening 48, and go out a lug 52 downwards at slotted hole 46 and between to slide opening 48.

See also Fig. 2, bayonet unit 50 is installed in loam cake 40 bottom surfaces, comprises a sliding part 54, a pothook 60 and a spring 72.Wherein sliding part 54 is one slidably to be installed in the plate body in the depression 44 of loam cake 40, and its length is slightly less than depression 44 length, and width equates with depression 44 width.Sliding part 54 bottom surfaces are provided with one and can cooperate and accommodate the protuberance 56 of slip in the slotted hole 46 of loam cake 40 depression 44, and protuberance 56 hollows out for finger from sliding part 54 end faces and places.Sliding part 54 1 sides are provided with accommodates the cylinder 58 of slip in the slide opening 48 of loam cake 40 depressions 44 a pair of can the cooperation, and each cylinder 58 is provided with internal thread.Pothook 60 is an elongate rod, the one lateral margin is provided with three can cooperate the barb 62 of accommodating in the chute 38 that is buckled in magnet stand 30, and each barb 62 can cooperate first inclined-plane 37 of magnet stand 30 listriums 36 and first hypotenuse 61 and second hypotenuse 63 on second inclined-plane 39 respectively its free-ended dual-side setting.Pothook 60 is offered a pair of through hole 64 that can pass and be locked together in the cylinder 58 of sliding part 54 for screw 66.Another lateral margin of pothook 60 projection 68 that stretches out, and projection 68 is provided with a fixed orifice 70.Spring 72 1 ends are fastened in the fixed orifice 70 of pothook 60, and its other end then is fastened in the lug 52 of loam cake 40 depressions 44.

During assembling bayonet unit 50, sliding part 54 is placed in the depression 44 of loam cake 40, and makes the protuberance 56 of sliding part 54 pass the slotted hole 46 of loam cake 40 depressions 44, the cylinder 58 of sliding part 54 is passed in the slide opening 48 of loam cake 40 depressions 44.Afterwards, pass the through hole 64 of pothook 60 and lock together, thereby pothook 60 is fixed on the bottom surface of loam cake 40 with the cylinder 58 of sliding part 54 by screw 66.Then, spring 72 1 ends are caught on the lug 52 of loam cake 40 depression 44, simultaneously its other end is caught on the fixed orifice 70 of pothook 60 projections 68.

See also Fig. 3, loam cake 40 is installed to pedestal 20 time, the elongated slot 29 of pedestal 20 side plates 24 is aimed at and passed to the L shaped folding hook 45 of loam cake 40, and promote loam cake 40 to front slide.At this moment, the L shaped folding hook 45 of loam cake 40 will block the flap 25 of pedestal 20 side plates 24, thus improper the moving of restriction loam cake 40 in the vertical directions.Simultaneously, first hypotenuse 61 of bayonet unit 50 barbs 62 will be resisted against first inclined-plane 39 of magnet stand 30 listriums 36 earlier, afterwards barb 62 by the structure of its first hypotenuse 61 gradually slippage cross listrium 36, and make spring 72 stretcher strains.After barb 62 is crossed listrium 36 fully, the one-piece construction that will drive pothook 60 under the elastic recovery of spring 72 oppositely moves and returns back to virgin state, so far barb 62 will catch on the listrium 36 of magnet stand 30 in the lump, thereby prevent that loam cake 40 from oppositely withdrawing from from pedestal 20.

During dismounting loam cake 40, the sliding part 54 of first push card buckle device 50 is lateral slip in the depression 44 of loam cake 40, moves along the A direction in the lump thereby drive pothook 60.At this moment, spring 72 will produce stretcher strain, and second hypotenuse 63 of pothook 60 barbs 62 will be against second inclined-plane 37 of magnet stand 30 listriums 36, and moves along the B direction, moves backward and withdraws from from the chute 38 of magnet stand 30 listriums 36 fully until barb 62 thereby drive whole loam cake 40.So far, the L shaped folding hook 45 of loam cake 40 is removed the buckle relation with the listrium 36 of magnet stand 30.Afterwards, loam cake 40 is mentioned from pedestal 20 can finish dismounting.
