Description

computer case

technical field

The utility model relates to a computer case, in particular to a computer case which can conveniently install and remove a cover plate.

Background technique

A general computer case usually includes a casing and a cover plate, and the casing is used for installing electronic devices, such as a motherboard, a hard disk, and a power supply. The casing generally includes a bottom plate, a front plate, a rear plate and two parallel side plates. The edges of the front plate and the rear plate form a folded edge respectively, and the folded edge is provided with a number of button holes. The cover plate is used to cover the casing, and a plurality of hooks protrude from the buckle holes corresponding to the front plate and the rear plate. During installation, snap the hooks of the cover plate into the corresponding buckle holes of the front plate and the rear plate, and then fix the cover plate on the casing by a screw. This method of screw locking is not only inconvenient to install the cover plate, but also often because the hooks of the cover plate are too tightly locked with the buckle holes of the front plate and the rear plate, after the screws are removed, it takes a long time to install the cover plate. Only a large force can release the engagement between the hook and the corresponding buckle hole, so it is very inconvenient to disassemble the cover plate.

Referring to FIGS. 1 to 4 , a preferred implementation of the computer case of the present invention includes a case 10 and a cover 30 that can be fixed on the case 10 .

The casing 10 includes a front panel 11 , a rear panel 12 and two side panels 13 , 14 . The front panel 11 and the rear panel 12 are parallel to and perpendicular to the two side panels 13 , 14 . The front panel 11 is bent inward by an arc-shaped edge 112 , and the rear panel 12 is vertically bent inward by an edge 122 .

A front edge of the cover plate 30 is bent corresponding to the curved edge 112 of the front panel 11 to bend a folded edge 35 , and the folded edge 35 is roughly in a “匚” shape. The rear edge of the cover plate 30 is bent inwards to a folded edge 31, and the two side edges of the cover plate 30 are respectively provided with a base 32, and the base 32 includes a base fixed on the cover plate 30. The base 321 and a vertical plate 322 perpendicular to the base 321, the connection between the base 321 and the vertical plate 322 is provided with a pivot hole 323, the vertical plate 322 is bent relative to the base 321 A folded piece 3221 , the folded piece 3221 is roughly in the shape of a “匚” and defines a positioning hole 3222 . At a substantially middle position between the two bases 32 , the cover 30 is provided with a receiving portion 34 , and the receiving portion 34 defines a through opening 341 .

The pivot hole 323 of the base 32 can be used to pivotally fix a rotating member 40 , the upper side of the rotating member 40 is provided with two mounting holes 41 , and the lower side of the rotating member 40 is opened corresponding to the receiving portion 34 An opening 42, the two ends of the rotating member 40 corresponding to the pivot holes 323 of the base 32 are respectively provided with a fixing hole 43, the rear side of the rotating member 40 is provided with a The through hole 44 has a hook 441 extending from one edge of the through hole 44 , and a plurality of locking protrusions 45 protrude from the rear end of the rotating member 40 , and each locking protrusion 45 has an inclined surface 451 .

A screw 50 is locked into the pivot hole 323 of the base 32 and the fixing hole 43 of the rotating member 40 to rotatably install the rotating member 40 on the cover plate 30 . An elastic element 60 is sheathed on the screw 50 , and the elastic element 60 is a torsion spring in this embodiment, which includes two protruding ends 61 , 62 . The protruding end 61 is hooked on the hook 441 of the through hole 44 , and the protruding end 62 directly passes through the positioning hole 3222 of the flap 3221 .

The receiving portion 34 can be used to accommodate a handle 70, the handle 70 includes a panel 71 and a connecting portion 72, the connecting portion 72 defines an opening 721, and the opening 721 can be used to accommodate an elastic piece 80, Two circular holes 722 are formed at ends of the connecting portion 72 corresponding to the two mounting holes 41 of the rotating member 40 .

The connecting portion 72 of the handle 70 can pass through the opening 341 of the receiving portion 34 and the end of the connecting portion 72 can be placed on the upper side of the rotating member 40, and the screw 90 is locked into the connecting portion 72 at the same time. The round hole 722 of the handle 72 and the mounting hole 41 on the upper side of the rotating member 40 are used to fix the handle 72 and the rotating member 40 together. The elastic piece 80 abuts against the panel 71 of the handle 70, and the two ends of the elastic piece 80 are respectively buckled on the two side edges of the opening 341 of the receiving portion 34, so that the elastic piece 80 is elastically fixed on the handle 70 .

Please refer to FIG. 5 , when installing the cover plate 30 , the folded edge 35 of the front edge of the cover plate 30 is buckled on the folded edge 112 of the front panel 11 of the casing 10 , and then the cover plate 30 is placed in the The connection between the folded edge 35 and the folded edge 112 is rotated axially downward until the inclined surfaces 451 of several locking projections 45 of the rotating member 40 installed on the cover plate 30 respectively abut against the casing 10 The edge of the hem 122 of the rear panel 12. Continue to press the cover plate 30 , the inclined surface 451 of the locking projection 45 is squeezed by the folded edge 122 so that the rotating member 40 moves away from the edge of the folded edge 31 on the cover plate 30 . When rotating in the first direction, at the same time, the elastic member 60 sleeved on the screw 50 is elastically deformed, and the screw 50 slides from one end of the pivot hole 323 to the other end. When the inclined surface 451 of the locking protrusion 451 slides away from the folded edge 122 and is not pressed by the folded edge 122, the elastic member 60 recovers elastically and drives the rotating member 60 toward the first Rotate in the second direction opposite to the direction, the screw 50 slides from the other end of the pivot hole 323 to one end, so that the folded edge 122 is tightly fastened to the folded edge 31 of the cover plate 30 and the folded edge 323. Between the two bases 32 , the cover 30 is thus fixed on the casing 10 . At this time, the flap 31 abuts against the edge 124 of the rear panel 12 of the casing 10 .

When disassembling, the panel 71 of the handle 70 on the cover plate 30 is pulled outward from the outside of the casing 10, and the elastic element 60 is elastically deformed to drive the rotating member 40 to rotate in the first direction ( As shown in Figure 6), at the same time, the inclined surface 451 of the card protrusion 45 of the rotating member 40 gradually slides away from the folded edge 122, and continues to pull the handle 70, so that the card protrusion 45 is completely separated from the The cover plate 30 can be detached from the casing 10 by folding the edge 122 . After the cover plate 30 is disassembled, the handle 70 is released, and the elastic element 60 recovers elastically, so that the rotating member 40 rotates along the second direction.
