The cover plate is fixed to the main casing by the hook on the cover plate and the slot on the main casing. However, when disassembling the above-mentioned chassis connected by the buckle method, it is necessary to push the cover body with a large force to make the hooks escape from the card slot, so the removal of the chassis is inconvenient, and the hook on the cover body is easy. A break occurred during the process of detachment.

In view of the above, it is necessary to provide a chassis that is easy to disassemble.

A chassis includes a first body, a second body, and a connection structure for connecting the second body to the first body. The connection structure includes a limiting slot formed on the first body and a clamping on the second body And a sliding button disposed on the second body and connected to the holding member, the holding member includes a limiting end, and the sliding sliding button is used to extend or stop the limiting end of the holding member The limiting body is provided with a connecting member on the first body, and the connecting member extends outward to form a convex portion, and the limiting portion forms a limit groove, and when the limiting end of the holding member is limited to the connecting member When the slot is in place, the second body is fixed to the first body.

A chassis includes a first body, a second body, and a connecting structure for connecting the second body to the first body. The connecting structure includes a first button formed on the first body, a slider disposed on the second body, and two The elastic members are respectively clamped on the sliding button and the second body, and the limiting end of the sliding button is formed on the sliding button, and the sliding button is pressed to force the elastic member to elastically deform and drive the limiting end into or out a limiting slot, the first body is provided with a connecting member, and the connecting member extends outward to form a convex portion, and the protruding portion forms a limited slot, when the limiting end of the sliding button is limited to the limiting slot on the connecting member The second body is fixed to the first body.

When the above-mentioned chassis is disassembled, the sliding slider can be used to drive the retaining end of the retaining member or the sliding button out of the limiting slot, and then only a small force is applied to the second body. The second body is detached from the first body, so the case is easy to disassemble. Moreover, since the limiting end only extends into the limiting slot on the first body, instead of engaging with the limiting element slot by means of elastic clamping, the limiting end of the holding component is from the first body When the upper limit groove is disengaged, it is not necessary to overcome the clamping force, so the disassembly force is small, and at the same time, the holding member can be prevented from being pulled due to repeated use.
