Detailed Description

Before the present utility model is described in detail, it should be noted that in the following description, like elements are denoted by the same reference numerals.

Referring to fig. 1, 2, 3, 4 and 5, the PCIe fixing device of the present utility model is combined with a chassis 90. The casing 90 has a mounting frame module 91, an extension plate 92 extending from the mounting frame module 91 in a direction away from the mounting frame module 91, and a slot unit 93 disposed on the extension plate 92 and spaced apart from the mounting frame module 91. The mounting frame module 91 has a mounting frame 911. The PCIe fixture includes a PCIe frame 1 and a fixture 2 for fixing the PCIe frame 1 to the mounting frame module 91.

The PCIe frame 1 includes a flap unit 11 coupled to the mounting rim 911 of the mounting frame module 91. The flap unit 11 has a fixed edge 12 coupled to the mounting rim 911.

The fixing device 2 is used for fixing the baffle unit 11 of the PCIe frame 1 on the mounting frame 911 and fastening the clamping groove unit 93 of the chassis 90, and includes a fixing base 3, and an elastic pressing module 4 disposed on the fixing base 3 and detachably fastening the clamping groove unit 93 of the chassis 90.

The fixing base 3 has a base 31 for positioning the fixing edge 12 of the blocking plate unit 11 on the mounting frame 911, a coupling slot module 32 extending from the base 31 toward the slot unit 93 of the housing 90, and a positioning boss 5 extending from the base 31 toward the mounting frame 911 and detachably penetrating the mounting frame 911.

The elastic pressing module 4 has an elastic pressing unit 41 coupled to the coupling slot module 32 of the fixing base 3 and capable of elastically moving relative to the coupling slot module 32, and a hook unit 42 extending from the elastic pressing unit 41 toward the hook unit 93 and capable of being driven by the elastic pressing unit 41 to be engaged with the hook unit 93. After the elastic pressing unit 41 is pressed and the hook unit 42 moves toward the direction of the coupling groove module 32 of the fixing base 3, the elastic pressing unit 41 accumulates an elastic restoring force, and the positioning boss 5 of the fixing base 3 penetrates the mounting frame 911 to make the base 31 of the fixing base 3 tightly position the fixing edge 12 of the blocking piece unit 11 on the mounting frame 911, at this time, the elastic pressing unit 41 is not pressed any more and the elastic pressing unit 41 releases the elastic restoring force to drive the hook unit 42 to move toward the direction of the hook unit 93, and the hook unit 42 is buckled with the hook unit 93.

When assembling, the elastic pressing unit 41 is pressed first, the elastic pressing unit 41 is elastically moved relative to the coupling groove module 32 of the fixing base 3 to move toward the coupling groove module 32, and the positioning boss 5 of the fixing base 3 penetrates the mounting frame 911 to make the base 31 of the fixing base 3 tightly position the fixing edge 12 of the blocking piece unit 11 on the mounting frame 911, at this time, the fixing edge 12 of the blocking piece unit 11 is already fixed on the mounting frame 911 and the hook unit 42 is aligned with the hook unit 93. Then, since the elastic pressing unit 41 is pressed to accumulate elastic restoring force, as long as the pressing force is not continuously applied to press the elastic pressing unit 41, the elastic restoring force released by the elastic pressing unit 41 drives the hook unit 42 to move toward the clamping groove unit 93, and the hook unit 42 is buckled with the clamping groove unit 93 as shown in fig. 4, so that the elastic pressing unit 41 is combined with the casing 90, and the risk that the elastic pressing unit 41 may cause the elastic pressing unit 41 to drive the positioning boss 5 of the fixing seat 3 to loosen and cause the fixing edge 12 of the baffle unit 11 to separate from the mounting frame 911 due to external factors such as vibration or false touch is avoided. At this time, the assembly operation of the fixture 2 to fix the flap unit 11 of the PCIe frame 1 to the mounting frame 911 is completed, effectively achieving tool-free assembly operation.

In contrast, when the spacer unit 11 of the PCIe frame 1 is to be detached from the mounting frame 911, the elastic pressing unit 41 is only pressed and the hook unit 42 is driven to move in a direction away from the slot unit 93, and after the hook unit 42 is separated from the slot unit 93 as shown in fig. 4, the positioning boss 5 of the fixing base 3 is detached from the mounting frame 911 to move the base 31 of the fixing base 3 from the fixed edge 12 of the spacer unit 11, and at this time, the fixed edge 12 of the spacer unit 11 is not forced to be fastened to the mounting frame 911 by the base 31, so that the entire spacer unit 11 can be easily detached from the mounting frame 911, thereby completing the detachment operation.

By means of the positioning boss 5 of the fixing base 3 penetrating the mounting frame 911, the fixing edge 12 of the baffle unit 11 is tightly positioned on the mounting frame 911 by the base 31 of the fixing base 3, and the elastic pressing module 4 is matched with the design of detachably fastening the clamping groove unit 93 of the casing 90, as long as the elastic pressing unit 41 is pressed and the elastic pressing unit 41 can accumulate the elastic restoring force, the positioning boss 5 of the fixing base 3 penetrates the mounting frame 911, and the fixing edge 12 of the baffle unit 11 is tightly positioned on the mounting frame 911 by the base 31 of the fixing base 3, at this time, the elastic pressing unit 41 is not pressed and the elastic pressing unit 41 releases the elastic restoring force to drive the clamping hook unit 42 to move towards the direction of the clamping groove unit 93, and the clamping hook unit 42 is fastened with the clamping groove unit 93, so that the baffle unit 11 is fixed on the mounting frame 911, the assembly operation is simple, the locking operation is not required, and the time and labor are saved, and the assembly efficiency is greatly improved.

It should be noted that, in the present embodiment, the coupling groove module 32 of the fixing base 3 of the fixing device 2 has a surrounding wall 321 disposed on the base 31 and extending from the base 31 toward the clamping groove unit 93, and two limiting openings 322 spaced apart from the surrounding wall 321. The elastic pressing unit 41 of the elastic pressing module 4 has two spacing parts disposed corresponding to the limiting openings 322 of the combining groove module 32, and can be engaged with the locking parts 411 of the limiting openings 322. When the elastic pressing unit 41 is pressed, the locking piece 411 does not engage the limiting opening 322; when the elastic pressing unit 41 is not pressed, the locking member 411 engages with the limiting opening 322. In short, through the design that the locking piece 411 of the elastic pressing unit 41 can be locked with the limiting opening 322 of the combining groove module 32 of the fixing base 3, when the elastic pressing unit 41 releases the elastic restoring force to drive the hook unit 42 to be locked with the clamping groove unit 93, the locking piece 411 of the elastic pressing unit 41 is blocked by the limiting opening 322 of the combining groove module 32, so that the problem that the hook unit 42 is excessively locked into the clamping groove unit 93 due to the elastic restoring force excessively released by the elastic pressing unit 41 is avoided, but the utility model is not limited thereto. In addition, in the present embodiment, the elastic pressing unit 41 of the elastic pressing module 4 further has a pressing body 412, and a spring 413 (see fig. 5) connecting the pressing body 412 and the combining groove module 32. The hook unit 42 is disposed on the pressing body 412 and extends from the pressing body 412 toward the slot unit 93. One of the opposite ends of the spring 413 is connected to the pressing body 412, and the other end extends into the coupling groove module 32 and is connected to the coupling groove module 32, but not limited thereto, as long as the elastic pressing unit 41 can elastically move relative to the coupling groove module 32, and the pressing body 412 pressing the elastic pressing unit 41 can drive the hook unit 42 to move toward the coupling groove module 32 of the fixing base 3, so that the pressing body 412 presses the spring 413 and accumulates elastic restoring force.

In addition, in the present embodiment, the mounting frame module 91 further has a slot 913 located on the opposite side of the mounting frame 911. The baffle unit 11 further has a baffle body 13 extending from the fixing edge 12 toward the slot 913 and capable of being inserted into the slot 913. The fixing base 3 of the fixing device 2 further has a blocking piece 33 extending from the base 31 toward the slot 913 of the mounting frame module 91. The blocking plate body 13 of the blocking plate unit 11 is inserted into the slot 913 and the fixing edge 12 is combined with the mounting frame 911, when the positioning boss 5 of the fixing base 3 penetrates the mounting frame 911 to enable the base 31 of the fixing base 3 to tightly position the fixing edge 12 of the blocking plate unit 11 on the mounting frame 911, the blocking plate 33 of the fixing base 3 abuts against and blocks the blocking plate body 13. In short, when the positioning boss 5 of the fixing base 3 penetrates the mounting frame 911 to enable the base 31 of the fixing base 3 to tightly position the fixing edge 12 of the baffle unit 11 on the mounting frame 911, the baffle 33 of the fixing base 3 abuts against the baffle body 13 of the baffle unit 11 as shown in fig. 4 to assist in positioning the baffle unit 11, but not limited thereto.

It is further noted that, in the present embodiment, the mounting frame 911 of the mounting frame module 91 has a limiting hole 912 for the positioning boss 5 of the fixing base 3 to penetrate into. The fixed edge 12 of the baffle unit 11 has a limiting hole 912 corresponding to the mounting frame 911 and a guiding slot 121 communicating with the limiting hole 912. The positioning boss 5 of the fixing base 3 passes through the guiding slot 121 and penetrates into the limiting hole 912 of the mounting frame 911 to fix and the base 31 of the fixing base 3 tightly positions the fixing edge 12 of the baffle unit 11. In short, the guiding groove 121 surrounds the corresponding limiting hole 912 as shown in fig. 2, so that the user can conveniently align the positioning boss 5 of the fixing base 3 with the limiting hole 912 and pass through the guiding groove 121 to penetrate the mounting frame 911, and ensure that the base body 31 of the fixing base 3 tightly bonds the fixing edge 12 of the blocking plate unit 11 to the mounting frame 911, but not limited thereto.

It should be noted that, for convenience of description, the above embodiment uses the fixing seat 3 of the fixing device 2 to fix the baffle unit 11 of the PCIe frame 1 to the mounting frame module 91 of the chassis 90 and uses the hook unit 42 of the elastic pressing module 4 of the fixing device 2 to match with the slot unit 93 of the chassis 90 for assembly, but not limited thereto, the above embodiment may be used according to practical requirements, for example: the PCIe frame 1 includes a plurality of baffle units 11, the chassis 90 has a plurality of slot units 93 spaced apart from each other and disposed on the extension board 92, so a plurality of fasteners 2 are required to be used to fix the baffle units 11 on the mounting frame 911 and respectively fasten the slot units 93 of the chassis 90, and the assembly operation of each fastener 2 is the same as the assembly description of the above embodiment, which is not repeated herein.

In summary, in the novel PCIe fixing device, the positioning boss 5 of the fixing base 3 penetrates the mounting frame 911 to enable the base 31 of the fixing base 3 to tightly position the fixing edge 12 of the baffle unit 11 in the direction of the mounting frame 911, and the fixing edge 12 of the baffle unit 11 is detachably fastened to the clamping groove unit 93 of the chassis 90 in cooperation with the elastic pressing module 4, so long as the elastic pressing unit 41 is pressed and the elastic pressing unit 41 accumulates the elastic restoring force, and the positioning boss 5 of the fixing base 3 penetrates the mounting frame 911 to tightly position the fixing edge 12 of the baffle unit 11 on the mounting frame 911 by the base 31 of the fixing base 3, at this time, the elastic pressing unit 41 is not pressed any more and the elastic pressing unit 41 releases the elastic restoring force to drive the clamping hook unit 42 to move in the direction of the clamping groove unit 93, and the clamping hook unit 42 is combined with the clamping groove unit 93, so that the baffle unit 11 can be fixed on the mounting frame 911.
