Patent ID: 7641297

Claim:
A rack mountable to a computer cabinet without using a tool, said rack being fixed inside said computer cabinet, the computer cabinet including at least one positioning hole, said rack comprising: a slide module, installed on a lateral surface of said computer cabinet; a latch element, comprising: a base, fixed on a lateral surface at an end of said slide module, and having at least one hook disposed on a lateral surface of said base; an embedding body, contained in said base, and having a limit element bent towards a bottom of said base, such that said limit element and the bottom of said base form a recess, and at least one protruding pillar disposed on said embedding body and proximate to said at least one hook; a braking member, included between said base and said embedding body, and having a pivotal connecting hole disposed at a position other than the center of said braking member, and an axle rod passing through said pivotal connecting hole and pivotally coupled with said base, such that said braking member maintains an appropriate distance from the bottom of said base, and said braking member is extended into said recess of said embedding body, a movable turning member being pivotally coupled to said braking member and disposed at an end of the braking member away from said pivotal connecting hole; thereby, said at least one hook is latched into the positioning hole of said computer cabinet, and said turning member is turned eccentrically by using said axle rod as a center and pressed on a lateral surface in said recess, and said at least one protruding pillar is extended into said positioning hole to press against the at least one hook of the base to prevent the at least one hook from separating from said positioning hole, and on the other hand, if said rack is disassembled, said turning member is returned to its original position, so that said braking member is pressed on a lateral surface inside said limit element, and said embedding body is moved accordingly to separate said at least one protruding pillar from said positioning hole, so as to achieve mounting and disassembling said rack without using a tool.
