Description

Computer chassis

The utility model mainly is about a kind of computer chassis, particularly about a kind of computer chassis with latching system with easy disassembly.

Prior art generally be directly panel lock to be fixed on the computer base by screw or bolt etc., but this mode can increase numerous and diverse degree of assembling when the assembling computer chassis, is not easy to user's operation.

For the handled easily person uses, industry has just proposed a kind of mode that panel is fixed to computer base by the buckle mode, it is by being provided with some grabs on computer panel, and corresponding elongated slot is set on pedestal, and then make the grab fastener in the elongated slot of pedestal, and panel can be fixed on the computer base.Though this mode is more convenient than the former in when assembling, with the panel skid during in computer chassis, the operator needs simultaneously with the hands level to promote panel to slide along computer base, and is very inconvenient in the operation.

The purpose of this utility model is to provide a kind of computer chassis of simple in structure, computer panel easy accessibility.

The purpose of this utility model is achieved through the following technical solutions: the utility model computer chassis mainly comprises a pedestal, a loam cake, a rotatable bracing frame and a latching system.Wherein this pedestal comprises a base and a pair of side plate that extends vertically upward along these base both sides, and the free end of each side plate further vertically extends a flanging inwardly, forms some elongated slots on each flanging respectively.Two ends, bottom surface of this loam cake form some grabs respectively, and in the elongated slot of corresponding fastener on pedestal, tops is recessed to form a ccontaining recess downwards on this, is a perforation at the middle part of this recess respectively.The rotation bracing frame is fixed in the pedestal, and its center offers a rectangular aperture, and this opening and bracing frame connection form first and second flange.This latching system comprises a turncap, a cam, a pad and a screw, turncap is placed in the recess of loam cake, and cam is placed the recess bottom of loam cake, by pad and screw turncap and cam is fixed in then to cover.When rotating turncap, cam can drive first and second flange of bracing frame and do corresponding the rotation, so that loam cake moves forward and backward along pedestal, and makes the grab of loam cake can snap in or break away from the elongated slot of pedestal.

Owing to adopted technique scheme, the utlity model has advantages such as simple in structure, easy accessibility.

In conjunction with the embodiments utility model is further described with reference to the accompanying drawings.

Please refer to Fig. 1, the utility model computer chassis 1 mainly comprises a pedestal 10, a loam cake 20, a rotation bracing frame 40 and a latching system 50.

Wherein this pedestal 10 comprises a base 12 and a pair of side plate 14 that extends vertically upward along these base both sides, the free end of each routine plate 14 further vertically extends a flanging 16 inwardly, form some elongated slots 17 on each flanging 16 respectively, returning apparatus has a magnet stand 30 in this pedestal 10.

Two ends, bottom surface of loam cake 20 form some grabs 21 (as shown in Figure 3) respectively, respectively in the elongated slot 17 of corresponding fastener on pedestal 10, these loam cake 20 tops are recessed to form a ccontaining recess 22 downwards, at the middle part of this recess 22 is a perforation 24, intersection in recess 22 and perforation 24 is an anchor ring 26, half indentation at least of this anchor ring 26 forming a semi-cylindrical revolution space 28, further is formed with two retainers 29 at the end of this revolution space 28.

This rotation bracing frame 40 is a sheet metal, be fixed in the top of this magnet stand 30, its center position is provided with a rectangular aperture 42, this opening 42 forms top 44 with bracing frame 40 joints, and this top 44 is made of relative sidepiece (indicating) first flange 46 of pair of parallel, second flange 48 and another.

Please together with reference to Fig. 2 and Fig. 3, this latching system 50 comprises a turncap 60, a cam 52, a pad 54 and a screw 56.Wherein the top of this turncap 60 is formed with a depression 62, and the place, transversal section, center of this depression 62 is formed with one handle 64, further is provided with a spline 66 at the bottom center place of this turncap 60; This cam 52 is that two ends are the square frame body of toroidal, and an end forms flag terminal 58, and the relative other end then forms a through hole 53 that is spline-like.

Please together with reference to Fig. 4, when latching system 50 is installed on loam cake, at first turncap 60 is placed in the ccontaining recess 22 of loam cake 20, so that the spline 66 on turncap 60 bottoms snaps in the perforation 24 of this ccontaining recess 22, then, cam 52 is placed the bottom of ccontaining recess 22, and the through hole 53 on the cam 52 is cooperated with spline 66, with preliminary stationary cam 52, and then pad 54 is placed the bottom of cam 52, and the center pit (not indicating) of this pad 54 is alignd with the through hole 53 of cam, at last, screw 56 is extended through the center of this pad 54 and the through hole 53 of cam 52, sealed fixing with the spline 66 of turncap 60, be about to latching system 50 and be fixed on the loam cake 20.

Please together with reference to Fig. 5, rotate the handle 64 on the turncap 60,, cam 52 does corresponding rotation so that being driven, so that its flag terminal 58 turns to arbitrary side plate 14 of pedestal 10, then loam cake 20 is placed on the pedestal 10, grab 21 on its two ora terminalis is snapped in respectively in the elongated slot 17 on the pedestal 10, and at this moment, latching system 50 will automatically enter in the opening 42 of rotation bracing frame 40.

Please together with reference to Fig. 6, during assembling, rotate the handle 64 of turncap 60 along the direction of arrow A among the figure, to drive the rotation that cam 52 is done in the same way, so that flag terminal 58 and second flange, 48 perpendicular abutment, at this moment, latching system 50 will drive loam cake 20 and move towards pedestal the place ahead, so that the grab 21 on the loam cake 20 respectively with pedestal 10 on elongated slot 17 snap fit mutually, and then loam cake 20 is fixed on the pedestal 10, and then make cam 52 rotation more in the direction of arrow A, replace mutually with any retainer 29 on the anchor ring 26 until it, so that cam 52 is locked between the retainer 29 and second flange 48.

Please together with reference to Fig. 7, during dismounting loam cake 20, the handle 64 of turncap 60 need only be rotated along the direction of arrow B among the figure, to drive the rotation that cam 52 is done in the same way, replace mutually with first flange 46 until flag terminal 58, at this moment, latching system 50 will drive loam cake 20 and move towards pedestal 10 rearward end, so that the grab 21 on the loam cake 20 breaks away from elongated slot 21, again loam cake 20 is directly taken out.
