Latch installable to various positioning holes of different specifications of computer rack without using tool

Abstract

The invention discloses a latch installable to various positioning holes of different specifications of a computer rack without using a tool. The latch is latched into each positioning hole on both side panels of the computer rack. The latch has a base with a side fixed to a bottom track. The base has at least one horizontally extended hook, first sheath and second sheath engaged with each other, and a manual turning member. During assembling, the hook is latched into the positioning hole, and the manual turning member presses the protruding pillar all the way into the positioning hole to prevent the protruding pillar from being separated from the positioning hole by abutting the hook to the protruding pillar. During dismantling, the manual turning member is returned to its original position, and the first and second sheathes are moved accordingly to separate the protruding pillar from the positioning hole.

1 . A latch installable to various positioning holes of different specifications of a computer rack without using a tool, and affixed to a bottom track of a slide track module, and the latch comprising:
 a base, with a lateral side fixed onto a bottom track, and having at least one horizontally extended hook disposed away from the base and fixed onto a lateral side of the bottom track;   a manual turning member, pivotally coupled to the base;   a first sheath, sheathed onto the manual turning member, and having an embedding groove disposed on the first sheath for accommodating the manual turning member, such that the first sheath changes its position by the manual turning member and moves parallelly, and the first sheath has an arc protruding pillar disposed in parallel with the hook;   a second sheath, sheathed onto the first sheath, and having a rectangular protruding pillar embedded onto the arc protruding pillar;   thereby, during assembling, the slide track module and the latch are assembled first, and then the hooks of the latch are latched into the positioning holes of the computer rack, and the manual turning member is pressed against the first sheath, so that the arc protruding pillar or the rectangular protruding pillar is inserted all the way into the positioning hole depending on the shape of the positioning hole, and the hooks are pressed by the protruding pillars and thus will not be separated from the positioning hole, and on the other hand, during dismantling, the manual turning member is returned to its original position, such that the first and second sheathes are moved accordingly, and the arc protruding pillar or the rectangular protruding pillar is separated from the positioning hole, so as to achieve the purpose of assembling or removing the latch without using a tool.   
   
   
       2 . The latch installable to various positioning holes of different specifications of a computer rack without using a tool as recited in  claim 1 , wherein the hooks come with a quantity of two. 
   
   
       3 . The latch installable to various positioning holes of different specifications of a computer rack without using a tool as recited in  claim 1 , wherein the arc protruding pillars or the rectangular protruding pillars come with a quantity of two. 
   
   
       4 . The latch installable to various positioning holes of different specifications of a computer rack without using a tool as recited in  claim 1 , further comprising a blocking plate disposed wherein the base and the hook. 
   
   
       5 . The latch installable to various positioning holes of different specifications of a computer rack without using a tool as recited in  claim 4 , wherein the second sheath has an elastic member disposed between the rectangular protruding pillars, and the elastic member precisely abuts a blocking plate of the base, such that the second sheath can slide on the first sheath with the support of the elastic member and the blocking plate. 
   
   
       6 . The latch installable to various positioning holes of different specifications of a computer rack without using a tool as recited in  claim 1 , wherein the manual turning member is pivotally coupled into the base by passing and installing a screw rod. 
   
   
       7 . The latch installable to various positioning holes of different specifications of a computer rack without using a tool as recited in  claim 1 , wherein the first sheath has an elastic stop member, and the stop member precisely presses on the second sheath to fix the second sheath into its position, and the resilience of the stop member resumes the first sheath to its original position when the manual turning member is returned to its original position. 
   
   
       8 . The latch installable to various positioning holes of different specifications of a computer rack without using a tool as recited in  claim 1 , further comprising an insert hole disposed on the manual turning member and at a position with its back facing the base for facilitating an insertion of a tool into the insert hole to control the manual turning member.
