Buckle device

Abstract

A snap-fit ​​device is provided for securing multiple storage devices on a circuit board unit of a server. The storage devices are spaced apart along a first horizontal direction. Each storage device includes a vertical plate. Each vertical plate has a positioning portion defining a recess. The snap-fit ​​device includes a column unit, a crossbar, and a connector. The crossbar can be pushed into the recess of the storage device. The connector is disposed on the crossbar. The crossbar is inserted into the recess and fixedly engaged with the column unit by the connector, causing the crossbar to press against the positioning portion in a direction closer to the circuit board unit, preventing the vertical plate from moving in a direction closer to the crossbar and away from the circuit board unit. This allows the crossbar to secure the vertical plate of the storage device in one go, facilitating rapid installation and positioning of the storage devices, thereby improving installation reliability and convenience.

Claims

1. A latching device suitable for installation within a server and for securing a plurality of storage devices disposed on a circuit board unit within the server, the storage devices being spaced apart along a first horizontal direction, each storage device including a vertical plate, each vertical plate having a recessed positioning portion on its side, each positioning portion defining a groove, the latching device comprising: a column unit fixed within the server; a crossbar detachably coupled to the column unit, the crossbar extending along the first horizontal direction and being pushable into the groove of the storage device along a second horizontal direction not parallel to the first horizontal direction and pressing against and securing the positioning portion of the storage device; and at least one connector disposed on the crossbar and detachably coupled to the column unit. The crossbar is inserted into the groove of the upright plate and is fixedly connected to the column unit by the connector. The crossbar presses against the positioning part of the upright plate in the direction closer to the circuit board unit. At this time, the upright plate of the storage device cannot move in the direction closer to the crossbar or away from the circuit board unit, so that the crossbar fixes the upright plate of the storage device.

2. The latching device as described in claim 1, wherein, The crossbar includes multiple slots arranged along the first horizontal direction. The openings of the slots face the upright plate of the storage device and allow the upright plate to be inserted and positioned. When the crossbar is inserted into the slots, the slots are respectively inserted by the upright plate of the storage device, and the upright plate of the storage device is positioned by the slots and cannot move in the first horizontal direction.

3. The latching device as described in claim 2, wherein, Each slot of the crossbar has a slot opening and a slot limiting portion further away from the storage device than the slot opening. The inner diameter of the slot opening in the first horizontal direction is greater than the thickness of the upright plate in the first horizontal direction, and the inner diameter of the slot opening in the first horizontal direction gradually decreases in the direction away from the storage device. During the process of the upright plate of the storage device being inserted into the slot, the slot opening guides the upright plate into the slot limiting portion. When the upright plate of the storage device is inserted into the slot, the upright plate of the storage device is limited by the slot limiting portion and cannot move in the first horizontal direction.

4. The latching device as described in claim 2, wherein, The crossbar includes a horizontal plate portion extending along the first horizontal direction, a first bent portion extending from the side of the horizontal plate portion near the storage device toward the circuit board unit, and a second bent portion extending from the side of the first bent portion away from the horizontal plate portion toward the storage device. The slot is formed in the first bent portion and extends to the horizontal plate portion and the second bent portion.

5. The latching device as claimed in claim 4, wherein, The crossbar also includes a third bend that extends from the side of the second bend away from the first bend toward the side of the crossbar.

6. The latching device as claimed in claim 4, wherein, The crossbar also includes a fourth bend that extends from the side of the crossbar away from the storage device along the extending direction of the first bend.

7. The latching device as claimed in claim 4, wherein, The column unit includes multiple columns, and the buckling device includes multiple connectors disposed on the crossbar and corresponding to the columns. The connectors are disposed on the horizontal plate portion of the crossbar and arranged along the first horizontal direction, and are detachably connected to the column unit. The crossbar is inserted into the groove of the upright plate and is fixedly connected to the column unit by the connectors.

8. The latching device as claimed in claim 7, wherein, Each column of the column unit has an internal threaded hole; each connector has a hand screw. The crossbar is inserted into the groove of the upright plate and the hand screw of the connector is aligned with the internal threaded hole of the column. The hand screw is locked into the internal threaded hole to fix the crossbar to the column. At this time, the crossbar presses against the positioning part of the upright plate in the direction closer to the circuit board unit.

9. The latching device as claimed in claim 7, wherein, The horizontal plate has a plurality of connecting holes that penetrate the horizontal plate. The connecting holes are arranged along the first horizontal direction and allow one end of the connecting member to pass through, so that the connecting member can be detachably disposed on the horizontal plate.

10. The latching device as claimed in claim 1, wherein, The server's circuit board unit has a circuit board and a plurality of connectors disposed on the circuit board and for insertion and connection of the stand plate of the storage device. Each stand plate of the storage device has an insertion portion for detachably inserting and connecting any connector. The insertion portion of the stand plate is inserted into and engaged with the connector, such that the groove of the positioning portion of the stand plate faces the crossbar.
