This lower cover 20 is provided with a plurality of fixed orifices 22, one edge of this lower cover 20 extends side plate 24 to this

loam cake

10,24 pairs of the side plates of this lower cover 20 should loam cake 10 side plate 15 be provided with a plurality of chutes 26, thereby a plurality of projections 16 of this loam cake 10 can be slidedly arranged in the described chute 26 this loam cake 10 and lower cover 20 are combined.

Please together referring to figs. 1 through Fig. 4, this construction of switch 40 comprises that a movable part 50 and that is installed on this loam cake 10 is installed on the fixture 60 of this lower cover 20.

This movable part 50 comprises a host rack 51 and is placed in this host rack 51 and first lever 56 and second lever 54 that cooperatively interact.This host rack 51 is made up of a upper strata frame 52 and lower floor's frame 53.This upper strata frame 52 has a flat board 520, and these flat board 520 edges are provided with a plurality of fixed orifices 522 to fixed orifice 14 that should loam cake 10, and its middle part is bent to form the tabs 524 of pair of parallel downwards, and each tabs 524 is provided with two perforatings 526,527.This lower floor's frame 53 has the sidewall 532 of a diapire 530 and pair of parallel, these diapire 530 1 ends are provided with a breach 531,532 pairs of each sidewalls should upper strata frame 52 perforating 527 be provided with a perforating 537, this oppose side wall 532 flanging 534 that stretches out, this flanging 534 is parallel with the flat board 520 of this upper strata frame 52, and it is corresponding with the fixed orifice 522 of this flat board 520 to be provided with a plurality of fixed orifices 536.This first lever 56 comprises one first end 562 and second end 564 on the other side, and this first end 562 is provided with a step 563, and these first lever, 56 middle parts are provided with a pair of through hole 566, and this is corresponding with the perforating 526 of this upper strata frame 52 to through hole 566.This second lever 54 comprises a press section 542, and these press section 542 1 ends are to lower recess and extend an abutting part 544, and a pair of lug 546 is extended in these 542 other end both sides, press section parallel beneath forward, and each lug 546 is provided with a through hole 548 near end.

This movable part 50 also comprises and is used to install this second lever 54 and first lever 56 torque spring 57 and two

pins

58,59 to this host rack 51.This torque spring 57 comprises one first coil 572 and one second coil 574.When this movable part 50 is installed, this pin 58 is arranged in the perforating 526 of these upper strata frame 52 1 sides, the through hole 566 of these first lever, 56 1 sides, first coil 572 of this torque spring 57, the through hole 566 of these first lever, 56 opposite sides and the perforating 526 of these upper strata frame 52 opposite sides successively, like this, this first lever 56 is installed in this host rack 51 and can rotates around this pin 58.The upper strata frame 52 that this first lever 56 is installed is placed on this lower floor's frame 53, and the perforating 527 of this upper strata frame 52 is aimed at the perforating 537 of this lower floor's frame 53.This pin 59 is arranged in the perforating 537 of these lower floor's frame 53 1 sides, the perforating 527 of these upper strata frame 52 1 sides, the through hole 548 of these second lever, 54 1 sides, second coil 574 of this torque spring 57, the through hole 548 of these second lever, 54 opposite sides successively, the perforating 537 of the perforating 527 of these upper strata frame 52 opposite sides and these lower floor's frame 53 opposite sides, like this, this second lever 54 is installed in this host rack 51 and can rotates around this pin 59.

After installing, as shown in Figure 3, this moment, this first lever 56 roughly was in vertical state, these torque spring 57 1 ends prop up first end 562 of this first lever 56, second end 564 of this first lever 56 passes the breach 531 of this diapire 530, the abutting part 544 of this second lever 54 is connected to flat board 520 lower surfaces of this upper strata frame 52, and these torque spring 57 other ends upwards prop up this abutting part 544.

Rotate this first lever 56 in the counterclockwise direction and first end 562 of this first lever 56 is contacted with these second lever, 54 1 edges, push first end 562 of this first lever 56 downwards, the step 563 of this first end 562 can be stuck in this second lever, 54 edges, as shown in Figure 4.At this moment, this first lever 56 is in horizontality, first end 562 that these torque spring 57 1 end elasticity compress this first lever 56 makes this first end 562 that the trend that breaks away from these second lever, 54 edges and be rotated in a clockwise direction be arranged, but the abutting part 544 of this second lever 54 is upwards pushed against by the other end of this torque spring 57, thus these second lever, 54 edges step 562 of compressing this first lever 56 downwards make it can not be along turning clockwise.When pushing the press section 542 of this second lever 54, first end 562 of this first lever 56 obtains discharging, and under the effect of torque spring 57, this first lever 56 is rotated in a clockwise direction to state as shown in Figure 3.

More than describe the movable part 50 of construction of switch 40 in the utility model in detail, thereby this movable part 50 cooperates the open and close that realize this computer chassis with this fixture 60.Referring again to Fig. 1, this fixture 60 has a diapire 62, these diapire 60 edges are provided with a plurality of fixed orifices 620 to fixed orifice 22 that should lower cover 20, and these diapire 60 middle parts extend one with these diapire 60 vertical walls 64 divided into two parts, Yi Bian this vertical wall 64 is near being provided with U-lags 640.

The fixed orifice 522,536 that uses screw (figure does not show) to be arranged in the movable part 50 of the fixed orifice 14 of this loam cake 10 and this construction of switch 40 can be installed on this movable part on this loam cake 10, and the fixed orifice 620 that uses screw (figure does not show) to be arranged in the fixture 60 of the fixed orifice 22 of this lower cover 20 and this construction of switch 40 can be installed on this fixture on this lower cover 20.

Please refer to Fig. 5, when this loam cake 10 is installed to this lower cover 20, the projection 16 of the side plate 15 of this loam cake 10 is positioned at chute 26 porch of these lower cover 20 side plates 24, second end 564 of first lever 56 of this movable part 50 is resisted against U-lag 640 the right of this fixture 60, pull first end 562 of first lever 56 of this movable part 50 in the counterclockwise direction, this loam cake 10 is moved to the left under the drive of this first lever 56, the projection 16 of this loam cake 10 slides the chute 26 that enters this lower cover 20, rotate to horizontality until this first lever 56 and be stuck in an edge of this second lever 54, the state that installs as shown in Figure 6.

Please refer to Fig. 7, when opening this loam cake 10, push the press section of this second lever 54, this first lever 56 rotates to roughly vertically state under the effect of torque spring 57, since install after this loam cake 10 be moved to the left an end distance from, this moment, second end 564 of this first lever 56 was resisted against this U-lag 640 left sides, pull first end 562 of this first lever 56 along clockwise direction, this loam cake 10 moves right under the drive of this first lever 56, the projection 16 of this loam cake 10 slides to the right in the chute 26 of this lower cover 20, slide to this chute 26 porch until this projection 16, then this loam cake 10 is removed.
