## Abstract

The present application discloses a quick disassembly structure for computer case, comprising: a first casing, a quick disassembly member, and a second casing. The quick disassembly member further includes a toggle pin component, a sliding plate, and an elastic component. A sliding limit groove of the sliding plate corresponds to a limit fastener of the first casing, a transmission plate of the sliding plate corresponds to a toggle extension member of the toggle pin component, and the elastic component is fixed to a first hook part of the first casing and a second hook part of the sliding plate, enabling a tenon of the second casing engaging with a third hook part of the sliding plate. Overcoming the issue of a conventional quick disassembly structure for computer case where the lateral push button cannot be moved for separating the first and second casings due to aging or damage, increased friction.

## Claims

### Claim 1

A quick disassembly structure for computer case, comprising:
a first casing, comprising:
a cover, including a hole passing through a top surface of the cover;
a first casing fastener, fixed to a bottom surface of the cover and adjacent to the hole, including a first hook part fixed to a side of the first casing fastener and a pivot shaft protruding on another side of the first casing fastener, the pivot shaft disposed below the hole; and
a limit fastener, disposed adjacent to a side of the first hook part, including a limit fixing groove surrounding a side of the limit fastener;
a quick disassembly member, comprising:
a toggle pin component, inserted through the hole at a side, the toggle pin component comprising:
a toggle pin component body;
a pivot hole, disposed on a side of the toggle pin component body, the toggle pin component body pivoted to the pivot shaft through the pivot hole; and
a toggle extension member, adjacent to the pivot hole and extends along the side of the toggle pin component body;
a sliding plate, disposed adjacent to the bottom surface of the cover, and comprising:
a sliding plate body;
a sliding limit groove, formed on a top surface of the sliding plate body and slides within the limit fastener;
a second hook part, disposed on a side of the sliding plate body;
a transmission plate, extended and fixed to the side of the sliding plate body, corresponding to the toggle extension member; and
a third hook part, which is adjacent to the transmission plate and fixed to the side of the sliding plate body; and
an elastic component, an end of the elastic component hooked by the first hook part, and another end of the elastic component hooked by the second hook part; and
a second casing, a side including a tenon corresponding to the third hook part;
wherein, when the toggle pin component is actuated, the toggle pin component rotates clockwise around the pivot hole as a rotating axis, driving the toggle extension member to push the transmission plate to move toward a first direction; while the toggle extension member pushes the transmission plate, the second hook part pulls and stretches the elastic component, and the third hook part moves toward the first direction to disengage from the tenon, causing the first casing and the quick disassembly structure to separate from the second casing toward a second direction.

### Claim 2 (depends on 1)

The quick disassembly structure for computer case of claim 1, wherein the limit fastener is disposed on a side of the pivot shaft.

### Claim 3 (depends on 1)

The quick disassembly structure for computer case of claim 1, wherein the first hook part is horizontally aligned with the second hook part.

### Claim 4 (depends on 1)

The quick disassembly structure for computer case of claim 1, wherein the toggle pin component is used to pull the first casing when the first casing and the quick disassembly structure separate from the second casing toward the second direction.

### Claim 5 (depends on 1)

The quick disassembly structure for computer case of claim 1, wherein a pin fastener is inserted through a top surface of the toggle pin component to secure the toggle pin component.

### Claim 6 (depends on 1)

The quick disassembly structure for computer case of claim 1, wherein a corner pillar is disposed on a top surface of the first casing, which is used to support the computer case.

### Claim 7 (depends on 1)

The quick disassembly structure for computer case of claim 1, wherein the material of the sliding plate is a steel plate treated by a hot-dip galvanizing treatment.

### Claim 8 (depends on 1)

The quick disassembly structure for computer case of claim 1, wherein a side of the third hook part includes a slanted opening, used to align the third hook part with the tenon when the first casing and the quick disassembly member are joined to the second casing toward a opposite direction of the second direction.

### Claim 9 (depends on 7)

The quick disassembly structure for computer case of claim 7, wherein after the third hook part is aligned with the tenon, the toggle pin component rotates counterclockwise around the pivot hole as a rotating axis, and the elastic component shrinks, causing the third hook part to hook the tenon.

### Claim 10 (depends on 1)

The quick disassembly structure for computer case of claim 1, wherein another side of the second casing is fixed with a second casing fastener, a side of the second casing fastener is fixed with a sleeve, and a side of the cover is fixed with a shaft part, leading the sleeve to be fitted over the shaft part.

### Claim 11 (depends on 1)

The quick disassembly structure for computer case of claim 1, wherein another side of the second casing is fixed with a second casing shaft component, a side of the cover includes a cover sleeve, the bottom of the cover is fixed with a cover fixing component, which is aligned with the cover sleeve, and the cover sleeve is fitted over the second casing shaft component.
