Extraction device

The invention relates to a removable device for filling a casing opening, in particular to a removable device which is fixed to the inner wall of the casing by the elastic force of the elastic piece.

In general, the removable device is mainly capable of being stuffed into the opening of a casing and can also be taken out from the opening of the casing. Accordingly, the removable device may be an electronic device having a special function, such as a removable hard disk, which may be assembled on the casing; or only a dummy cover for the casing. When it is idle, it covers the opening and protects the inside of the casing, and when the space of the casing needs to be utilized, it is pulled out from the casing.

As shown in the seventh figure, a conventional removable device 10 is used to seal the idle portion 200 of the surface of a machine 20 to prevent external contaminants from invading the interior of the machine 20. The removable device 10 is basically a metal case, which is followed by the elastic portion of the metal elastic piece 11 on the side to the idle portion 200 of the machine table 20, and an opening 12 is provided in the front panel for the user. The fingers are extended into the opening 12 to facilitate the removal of the removable device 10 from the idle portion 200 of the table 20. However, when being placed in the idle portion 200 of the machine table 20, the removable device 10 is mainly in contact with the inner side wall of the idle portion 200 by a bump 110 on the metal dome 11, and the fixing force thereof is relatively Not ideal, it is easy to fall off due to vibration or external force.

As shown in the eighth figure, in view of the unsatisfactory fixing force of the metal dome, another conventional removable device 30 has a fastener 322 as shown in the above, in addition to the metal dome 33 as described above, for the extraction device. 30 is inserted When the idle portion 400 of the machine table 40 is inserted, a buttonhole 314 on the side wall of the machine table 40 is correspondingly fastened to strengthen the fastening. However, when the removable device 30 needs to be removed, the release of the button 321 on the front panel 301 is required to release the fastener 322 from the buckle hole 314, thereby causing the removable device 30 to be removed. It is removed from the idle portion 400 of the machine table 40. It can be seen that the removable device 30 has the dual purpose of being able to extract and firm, but increases the complexity of its structure.

The present invention provides a removable device having a simple structure and a high fixing force for plugging an opening in a casing. The removable device can be an electronic device or a dummy cover including a substrate, two horizontal side plates and two vertical side plates.

The substrate has a size corresponding to the opening of the casing. The two horizontal side plates are vertically disposed face to face on the top and bottom sides of the substrate. The two vertical side plates are vertically disposed face to face on opposite sides of the substrate for abutting against the opposite inner side walls of the casing.

Each vertical side panel includes a body and at least one elastic piece. The body has at least one opening and a first side and a second side on both sides of the opening. The first side of the body is adjacent to a side of the substrate, and the second side of the body is away from a side of the substrate. The elastic piece protrudes from the outer side of the body substantially corresponding to the opening of the body, and has a descending slope extending from the second side of the body and a steep slope extending from the descending slope. The steep slope segment is adjacent to the first side of the body and is suspended from the opening of the body, and the length of the ramp section is longer than the length of the steep slope section.

Preferably, the two horizontal side plates each have a plurality of elastic pieces thereon for contacting adjacent casings or other devices to generate electromagnetic wave interference (EMI) prevention effects.

Thereby, since the elastic piece of the removable device of the present invention enters the opening of the casing from the longer steep slope section before the longer steep slope section, the resistance is relatively low, so the user can easily The removable device is inserted into the housing. Moreover, once the removable device is inserted into the casing, the elastic pieces on the two sides are squeezed and moved a distance to accumulate a large elastic force, and finally the two sides of the casing are almost entirely attached to the casing. Relative to the inner side wall. In this way, the elastic piece can be strongly pressed against the inner side wall of the casing by the elastic force, so that the removable device can be stably stuck in the casing, and is not easily detached by vibration or external force.

Further, since the structure of the removable device of the present invention is relatively simple and does not require the use of a structure such as a card fastener, it can be taken out from the casing by applying an appropriate external force if necessary. Therefore, the present invention is simpler and more convenient in disassembly, assembly and maintenance. Other inventive aspects and more detailed technical and functional descriptions of the present invention are disclosed in the following description.

The first to fourth figures show a preferred embodiment in which the removable device 5 of the present invention is plugged into the opening 60 of a casing 6. As shown in the first figure, the casing 6, such as a server casing, has three openings 60 that are originally connected, wherein the bottommost opening 60 has been occupied by one of the extracting devices 5, and the other is extracted. The device 5 will be assembled to the intermediate opening 60 of the casing 6. In the preferred embodiment, the removable device 5 is provided with a dummy cover. The manner of presenting, but not limited to, the removable device of the present invention may also be an electronic device having a specific function, such as a removable hard disk or a compact disk.

Referring to Figures 1 and 2, the removable device 5 includes a substrate 50, two horizontal side panels 51, 53 and two vertical side panels 52,54. The substrate 50 is sized to correspond to the opening 60 of the casing 6, so that the opening 60 can be sealed after the removable device 5 is placed in the casing 6. The substrate 50 has a plurality of vents 500 for airflow. Circulation inside and outside. The two horizontal side plates 51, 53 are vertically disposed on the top side 501 and the bottom side 503 of the substrate 50 face to face. The two horizontal side plates 51, 53 each have a plurality of elastic pieces 510, 530 for abutting the casing 6 or other devices up and down, in addition to preventing electromagnetic interference (EMI), and also providing partial clamping and fixing effects. Similarly, the two vertical side panels 52, 54 are disposed face to face perpendicularly on opposite sides 502, 504 of the substrate 50 for abutting against the opposing inner side walls 61, 62 of the housing 6.

The two side edges 502, 504 of the substrate 50 of the removable device 5 are respectively convexly provided with a blocking piece 505 perpendicular to the vertical side plate 52 or 54. Thus, when the removable device 5 is placed in the casing 6, the blocking piece 505 of the substrate 50 can just abut against the frame of the opening 60 of the casing 6, preventing the entire removable device 5 from falling into the casing. Within 6.

As shown in the enlarged view of the second figure, the vertical side plates 52 and 54 each include a body 55 and at least one elastic piece 56. Since the elastic pieces 56 located on the vertical side plates 52 and 54 have the same structure, the vertical side plate 52 will be exemplified below. The body 55 has at least one opening 550 and a first side 551 and a second side 552 on opposite sides of the opening 550. The first side 551 is adjacent to the side 504 of the substrate 50, and the second side 552 is away from the side 504. On the other hand, the elastic piece 56 protrudes from the outer side of the body 55, and has a descending slope section 561 extending from the second side 552 of the body 55 and extending from the gentle slope A steep downhill section 562 of section 561. The steep section 562 of the shrapnel 56 is adjacent to the first side 551 of the body 55 and is suspended from the opening 550 of the body 55, and the length of the ramp section 561 is longer than the length of the steep section 562.

Referring to the third figure, since the elastic piece 56 of the removable device 5 of the present invention enters the opening 60 of the casing 6 from the longer steep slope portion 562 before the longer steep slope portion 562, the resistance is relatively higher. Low, so the user can easily insert the removable device 5 into the casing 6. Moreover, once the removable device 5 is inserted into the opening 60 of the casing 6, as shown in the fourth figure, the elastic piece 56 is pressed by the inner side wall 61 of the casing 6 and moved inward for a distance to be accumulated. The large elastic force finally reaches the inner side wall 61 of the casing 6 with the entire side flat, so that the elastic piece 56 can strongly press against the inner side wall 61 of the casing 6 by the elastic force. Therefore, the removable device 5 can be stably stuck in the casing 6, and is not easily detached by vibration or external force. Therefore, in the absence of a structure such as the fastener 322 as described in the prior art, the fixing ability of the extracting device of the present invention when it is inserted into the casing is relatively large.

As shown in the fifth and sixth figures, it shows the cooperation between the other elastic piece 56a on the vertical side plate 52 and a broken hole 63 on the casing 6. The housing 6 has more than one hole 63 (refer to the first figure), which is originally used to fasten the fasteners on both sides of a hard disk device, thereby holding the hard disk device in the casing. 6 in. For the same reason as described above, the user can easily insert the removable device 5 into the casing 6. However, it is particularly noted that, as shown in the sixth figure, the longer of the other elastic piece 56a is raised. The slope portion 561a and the shorter steep slope portion 562a are located in the hole 63. When the extraction device 5 is subjected to a force caused by vibration or other reasons and is intended to be retracted from the casing 6, the force is applied. Must be large enough to steep the shrapnel 6 The slope top of the downslope section 562a is pressed into the opening 550 from the breaching hole 63, so that the removable device 5 can be retracted outward. This shows that the removable device 5 is not easily retracted outward. In short, when the removable device 5 is inserted into the casing 6, the ramp portion 561 of the at least one shrapnel 56 is steeply lowered. The arrangement of the slope section 562 just within the breach 63 will effectively increase the fixing ability of the removable device 5 when it is inserted into the casing 6, making the extraction device 5 less likely to retreat outward. If there are more ascending ramp segments 561 and steep descending ramp segments 562 of the supporting shrapnel 56 located in the corresponding broken holes 63, respectively, the fixing ability of the extracting device 5 when it is inserted into the casing 6 Will be even better.

In addition, the structure of the removable device of the present invention is relatively simple and can be taken out from the casing by applying an appropriate external force if necessary without further resorting to the structure of the fastener 322 or the like in the prior art. Therefore, the present invention is simpler and more convenient in disassembly, assembly and maintenance.

In any event, anyone can obtain sufficient teaching from the description of the above examples, and it is understood that the present invention is indeed different from the prior art, and is industrially usable and progressive. It is the invention that has indeed met the patent requirements and has filed an application in accordance with the law.
