Locking member and box thereof

A box comprising:

• an upper cover and a lower cover rotatably connected with the upper cover so as to open and close the box;
• and wherein when the box is closed, contact surfaces between the upper cover and the lower cover are end surfaces, and surfaces of the upper cover and the lower cover that are relative to a first rotation position thereof are vertical surfaces;
• two locking members that each of the two locking members comprises a first locking component and a second locking component opposite to each other, wherein the first locking component is installed on the vertical surface of the upper cover and the second locking component is installed on the vertical surface of the lower cover;
• and wherein
• the first locking component comprises a first base and a fastener rotatably connected to the first base, a locking space provided on a side of the fastener that faces the first base;
• the fastener rotating relative to the first base from a second rotation position thereof so that the fastener rotates to move close to or move away from the first base, for achieving a lock or an unlock thereof;
• and wherein
• the second locking component comprises a second base and a deformable locking portion mounted on the second base, wherein the deformable locking portion is arranged on a first surface of the second base that is away from the first base;
• and wherein
• a second surface of the first base that faces the second base is provided with a first protrusion and a first receiving portion;
• a third surface of the second base that faces the first base is provided with a second protrusion and a second receiving portion;
• and wherein
• when both the upper cover and the lower cover are closed and the locking member is locked, the first base and the second base are opposite to each other, and the first protrusion is located in the second receiving portion, the second protrusion located in the first receiving portion, and the first base and the second base synchronously embedded into the locking space;
• and wherein the deformable locking portion is pressed against an inner wall of the fastener in the locking space when the locking member is locked, so as to engage with the fastener and prevent the first base and the second base from detaching from each other;
• and wherein
• when the fastener rotates away from the second base, the second base disengages from the first base causing the locking member to be unlocked;
• and wherein
• when the locking member is unlocked, both the first protrusion and the second protrusion protrude from the end surface, and are served as support feet for supporting the box.
