Cover plate for chassis

1. A cover plate for locking a chassis, the cover plate comprising:

a first cover section provided on top of the chassis;

a second cover section provided on top of the chassis and comprising a positioning pin;

a resilient lock defining a through hole corresponding to the positioning pin;

wherein when the resilient lock is in a first position, the positioning pin is latched in the through hole, one end of the first cover section abuts against one end of the second cover section, and the cover plate is locked; and

wherein when the resilient lock is in a second position, the positioning pin is removed from the through hole, the first cover section is slid toward the second cover section, and the cover plate is unlocked.

2. The cover plate of claim 1 , further comprising a plurality of lead pins fixed between the first cover section and the second cover section; the first cover section and the second cover section are fixed to the chassis through the lead pin.

3. The cover plate of claim 2 , wherein one end of the plurality of lead pins is fixed to the first cover section and the second cover section; and the other end of the plurality of lead pins is spaced a predetermined distance from the first cover section and the second cover section.

4. The cover plate of claim 1 , wherein one end of the positioning pin is fixed to a side surface of the second cover section; another end of the positioning pin is spaced a predetermined distance from the second cover section and is latched in the through hole.

5. The cover plate of claim 4 , wherein the positioning pin is a rivet; a screw of the rivet is passed through the through hole and fixed to the second cover section; a nut of the rivet is latched in the through hole.

6. The cover plate of claim 1 , wherein the resilient lock is located at a junction between the first cover section and the second cover section; the through hole is defined in the resilient lock adjacent to the second cover section.

7. A chassis comprising:

a side plate;

a cover plate fixed on the side plate and comprising a first cover section and a second cover section;

a hard disk drawer slidably coupled to the side plate; and

a hard disk fixed within the hard disk drawer;

wherein the cover plate further comprises a resilient lock, a side of the second section comprises a positioning pin, the resilient lock defines a through hole corresponding to the positioning pin;

wherein when the hard disk drawer is slid toward the side plate, the resilient lock is resiliently deformed, and the positioning pin is latched within the through hole, one end of the first cover section abuts against one end of the second cover section, and the cover plate is locked; and

wherein when the hard disk drawer is slid away from the side plate, the resilient lock is restored, the positioning pin is removed from the through hole, the second cover section is slid away from the first cover section, the first cover section is slid toward the second cover section, and the cover plate is unlocked.

8. The chassis of claim 7 , wherein the cover plate further comprises a plurality of lead pins fixed on two sides of the first cover section and the second cover section; the side plate defines openings corresponding to the lead pins; the first cover section and the second cover section are fixed to the side plate through the lead pins and the openings.

9. The chassis of claim 8 , wherein the opening is L-shaped; the plurality of lead pins are latched in one end of the openings, and the lead pins are removed from the openings through another end of the openings.

10. The chassis of claim 8 , wherein the plurality of lead pins are a rivets; a screw of the rivet is fixed to a side surface of the first cover section and the second cover section, and a nut of the rivet is latched in an end of the opening.
