Latch installable to various positioning holes of different specifications of computer rack without using tool
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. Field of the Invention
The present invention relates to a latch installable to various positioning holes of different specifications of a computer rack without using a tool, and more particularly to a sliding track module installed to various positioning holes of different shapes of a computer rack without using a tool.
2. Description of the Related Art
As communication networks are developed rapidly, servers are used as a contact window or a data collection area for the communications of a company or a larger event in addition to personal computers, and servers are generally placed in a computer rack, and the computer rack has an opening at its front side for putting the servers into the computer rack, and side panels 100 on both sides of the opening respectively. Referring to
Further, the positioning hole on the computer rack can be in an arc shape or its size can be different, and thus the fixing member 204 must be designed in correspondence with the shape and the size of the positioning hole 101, and such requirement makes the application relatively inconvenient.
SUMMARY OF THE INVENTIONIn view of the foregoing shortcomings of the prior art, the present invention provides a further improvement.
It is a primary objective of the present invention to provide a convenient way of installing a slide track module to a computer rack without using a tool.
Another objective of the present invention is to provide a latch applicable for various positioning holes of different specifications, shapes and sizes of a computer rack.
To achieve the foregoing objective, the present invention adopts a technical measure of installing latches in a computer rack, and both lateral sides of the computer rack have vertically arranged positioning holes, and the latch is latched into each positioning hole, and each latch has a base, and a lateral side of the base is fixed onto a bottom track of the slide track module, and the base has at least one horizontally extended hook, and the base is pivotally coupled to a manual turning member. The base further includes first and second sheathes engaged with each other, and the first sheath has an arc protruding pillar, and the second sheath has a rectangular protruding pillar.
During assembling, the hook is latched into the positioning hole of the computer rack, such that the manual turning member abuts the first or second sheath to insert the arc or rectangular protruding pillar all the way into the positioning hole and abuts the hook to the protruding pillar depending on the shape of the positioning hole to prevent the protruding pillar from being separated from the positioning hole. During dismantling, the manual turning member is turned back to its original position by a tool, such that the first and second sheathes are moved accordingly to separate the arc or rectangular protruding pillar from the positioning hole, so as to achieve the effect of installation and removal without using a tool.
The present invention relates to a latch installable to various positioning holes of different specifications of a computer rack without using a tool as shown in
Referring to
Further, a lateral side of the base 21 that is away from the bottom track 31 has at least one horizontally extended hook 211, which are upper and lower hooks 211 in this embodiment. The base 21 has a blocking plate 212 disposed between the hooks 211, and the base 21 has a pivotal hole 213 disposed thereon. The pivotal hole 213 has a manual turning member 22 disposed thereon, and the manual turning member 22 has a pivotal hole 221, and the manual turning member 22 is pivotally coupled to the base 21 by passing a screw rod 223 through the pivotal hole 213, 221 and secured with the slide track module 30. The manual turning member 22 has an insert hole 222 disposed proximate to the pivotal hole 221 and with its back facing the base 21 for facilitating the insertion of a tool (such as a screwdriver) to control the manual turning member 22.

Claims
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.
