Abstract

A latching structure includes a first plate, a second plate and a sliding plate disposed on a surface of the first plate and movable in a first direction. The first plate includes first arches each having an alignment hole in the first direction. The second plate includes second arches each having a latching hole in the first direction. The sliding plate includes pins corresponding to the latching holes. When the alignment hole accommodates the second arch and the sliding plate is located at a latching position, the pin is located in a corresponding latching hole to block separation of the first plate from the second plate in a second direction. When the sliding plate is located at a retracted position, the pin separates from the corresponding latching hole to allow separation of the first plate from the second plate in the second direction.

First claim

What is claimed is:

1 . A latching structure comprising:
a first plate comprising a plurality of first arches projecting from a first surface of the first plate and recessed from a second surface of the first plate, the first arches each having an alignment hole passing underneath each of the first arches in a first axial direction, wherein the first surface is opposite to the second surface; a second plate comprising a plurality of second arches each having a latching hole, wherein each of the second arches is adapted to be accommodated by a corresponding one of the alignment holes, and each of the latching holes passes underneath each of the second arches in the first axial direction; and a sliding plate comprising a plurality of pins respectively corresponding to the latching holes, the sliding plate disposed on the first surface of the first plate and movable between a latching position and a retracted position in the first axial direction; wherein when each of the alignment holes accommodates a corresponding one of the second arches and the sliding plate is located at the latching position, the pins are each located in a corresponding one of the latching holes to block separation of the first plate from the second plate in a second axial direction perpendicular to the first axial direction; when the sliding plate is located at the retracted position, the pins each separates from the corresponding one of the latching holes to allow separation of the first plate from the second plate in the second axial direction.

2 . The latching structure according to claim 1 , wherein each of the pins are longer than each of the latching holes.

3 . The latching structure according to claim 1 , wherein the first plate is a side plate of a communication device, the sliding plate comprises a pinch portion disposed adjacent to a bottom portion of the communication device, and when the sliding plate is located at the retracted position, the pinch portion projects out from the bottom portion of the communication device.

4 . The latching structure according to claim 3 , wherein the second plate has a pinch space disposed corresponding to the pinch portion.

5 . The latching structure according to claim 1 , wherein the first arches are disposed on four corners of the first plate.

6 . The latching structure according to claim 1 , wherein the first plate has a first recess portion and a second recess portion, the sliding plate further comprises an elastic positioning portion;
when the sliding plate is located at the retracted position, the elastic positioning portion is fit into the first recess portion; when the sliding plate is located at the latching position, the elastic positioning portion is fit into the second recess portion.

7 . The latching structure according to claim 1 , wherein the first plate and the sliding plate respectively comprise a positioning rib and a positioning groove;
when the sliding plate moves between the latching position and the retracted position in the first axial direction, the positioning rib abuts against the positioning groove.

8 . The latching structure according to claim 7 , wherein the positioning rib and the positioning groove are configured to block separation of the sliding plate from the first plate in the second axial direction when the sliding plate moves between the latching position and the retracted position in the first axial direction.

9 . The latching structure according to claim 1 , wherein the first plate further comprises a plurality of restraining portions disposed on two opposite sides of the first plate and projecting from the first surface, and the restraining portions are configured to restrict the sliding plate to moving in the first axial direction and blocking separation of the sliding plate from the first plate in the second axial direction when the sliding plate is located at the retracted position.

10 . The latching structure according to claim 9 , wherein the sliding plate further comprises a plurality of elastic arms disposed on two opposite sides of the sliding plate and corresponding to parts of the restraining portions, the elastic arms each comprises a hook, and when the sliding plate is located at the latching position, the hook is coupled with a corresponding one of the restraining portions.
