DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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 FIG. 2, and the latch is installed in a computer rack. In this preferred embodiment, the computer rack is a rack having an opening, and side panel 10 disposed separately on both lateral sides of the rack, and the side panels 10 have panels 11 extended towards the opening of the computer rack, and the panels 11 have a plurality of vertically arranged positioning hole 12, and the positioning holes 12 can be in a circular or rectangular shape (most positioning holes of the computer rack are in a circular shape or a rectangular shape, and the cross-sectional area of the rectangular shape is larger than the circular shape).
Referring to FIGS. 2 to 6, each positioning hole 12 is engaged to a latch 20, and the latch 20 has a base 21, and a lateral surface of the base 21 is affixed onto a bottom track 31 of the slide track module 30, and the bottom track 31 has a slide track 32 disposed movably thereon, and the movable slide track 32 is affixed onto the slide track module 30 and moved back and forth in the computer rack (as shown in FIG. 2).
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.
Referring to FIGS. 6 and 7, the base 21 has first and second sheathes 23, 24 engaged with each other and pivotally coupled to the manual turning member 22, wherein the first sheath 23 has outwardly extended and parallel arc protruding pillars 231, and the first sheath 23 has an embedding groove 233 for embedding the manual turning member 22 such that the manual turning member 22 can be turned in the embedding groove 233 and pressed onto the first sheath 23 for controlling the first sheath 23 to move parallelly. The first sheath 23 has an elastic stop member 232 disposed between the arc protruding pillars 231, and the second sheath 24 has an outwardly extended rectangular protruding pillar 241, and the rectangular protruding pillars 241 can be sheathed precisely onto the arc protruding pillars 231. The second sheath 24 has an elastic member 242 disposed between the rectangular protruding pillar 241, and the elastic member 242 precisely abuts the blocking plate 212, such that the second sheath 24 can slide on the first sheath 23 by the support of the elastic member 242 and the blocking plate 212.
Referring to FIG. 8, if the positioning hole 12 is a rectangular hole, the slide track module 30 and the latch 20 are combined with each other first, and then the hook 211 on the latch 20 is latched into the positioning hole 12 of the computer rack and pressed again the first sheath 23 by the manual turning member 22, and a stop member 232 in the first sheath 23 abuts the second sheath 24, such that the first and second sheaths 23, 24 are moved towards the positioning holes 12 to compress the elastic member 242 until the rectangular protruding pillar 241 on the second sheath 24 is inserted into the positioning hole 12, and the first sheath 23 enters into the positioning hole 12 through an arc protruding pillar 231 covered by the rectangular protruding pillar 241. The second sheath 24 is blocked by the stop member 232 and will not be withdrawn from the positioning hole 12, so that the hook 211 is pressed by the rectangular protruding pillar 241 and will not be separated from the positioning hole 12. On the other hand, during dismantling, the manual turning member 22 is returned to its original position or a tool is inserted into the insert hole 222, and the first sheath 23 resumes its original position by the resilience of the stop member 232 to separate the rectangular protruding pillar 241 from the positioning hole 12. In the meantime, the second sheath 24 synchronously resumes its original position by the resilience of the elastic member 242, so as to achieve the effect of removing the slide track module 30 from the computer rack without using a tool (as shown in FIG. 10).
Referring to FIG. 9, if the positioning hole 12 is a circular hole, the slide track module 30 and the latch 20 are combined with each other first, and then the hook 211 on the latch 20 is latched into the positioning hole 12 of the computer rack, and the manual turning member 22 abuts the first sheath 23, and the stop member 232 in the first sheath 23 abuts the second sheath 24, such that the first and second sheaths 23, 24 are moved towards the positioning hole 12 to compress the elastic member 242. When the elastic member 242 reaches the position of the positioning hole 12, the elastic member 242 is blocked outside the positioning hole 12 due to the different size and different shape of the rectangular protruding pillars 241 of the second sheath 24 and will not move forward together with the arc protruding pillar 231 of the first sheath 23. When the manual turning member 22 is turned towards the first sheath 23 continuously, the arc protruding pillar 231 of the first sheath 23 will enter into the positioning hole 12, and the hook 211 abuts the arc protruding pillar 231 and will not be separated from the positioning hole 12. Since the second sheath 24 cannot be moved forward synchronously with the first sheath 23, therefore the stop member 232 will produce a pulling and dragging tension. On the other hand, during dismantling, it is necessary to return the manual turning member 22 to the original position or insert a tool into the insert hole 222, and then the first sheath 23 resumes its original position by the resilience of the stop member 232. In the meantime, the second sheath 24 resumes its original position synchronously by the resilience of the elastic member 242, so as to achieve the effect of removing the slide track module 30 from the computer rack without using a tool (as shown in FIG. 10).
In summation of the description above, the present invention enhances the prior art and also complies with the patent application requirements. The description and its accompanied drawings are used for describing preferred embodiments of the present invention, and it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
