Locking mechanism and computer system with same

The invention discloses a locking mechanism and a computer system with the same. The locking mechanism in a slot of a computer case comprises a gear, a rack body, a push rod latch, a push rod body and a case latch. When the choke is in the closed position and the chassis latch engages a notch in the pushrod body, the gear, the rack body, the pushrod latch, the pushrod body, and the chassis latch cooperate to limit opening of the choke. 本发明公开一种锁定机构以及具有此机构的电脑计算机系统，其中在计算机机箱的插槽内的锁定机构包括齿轮、齿条本体、推杆闩锁、推杆本体以及机箱闩锁。当阻风门在关位置，且机箱闩锁卡合推杆本体上的缺口时，齿轮、齿条本体、推杆闩锁、推杆本体以及机箱闩锁协作以限制阻风门打开。
