Description

Technical Field

[0001] This invention relates to a slide rail fixing device, and more particularly to a telescopic slide rail fixing device. Background Technology

[0002] Existing telescopic slide rail fixing devices are used to position a slide rail assembly in a server rack. The slide rail assembly is designed to support a server and allow the server to move back and forth relative to the server rack. The telescopic slide rail fixing device includes at least two components capable of relative forward and backward movement. This design allows the overall length of the telescopic slide rail fixing device to be adjusted to accommodate server racks of different sizes. However, when at least a portion of the at least two components overlaps, shortening the overall length of the telescopic slide rail fixing device, the overall thickness of the telescopic slide rail fixing device increases at the overlapping portion. This causes the heat generated by the server during operation to be blocked by the telescopic slide rail fixing device, resulting in poor server heat dissipation. To solve the problem of poor server heat dissipation, multiple ventilation holes are usually provided on the telescopic slide rail fixing device, but this also leads to the problem of deformation of the telescopic slide rail fixing device when the server supported by the slide rail assembly is too heavy. Summary of the Invention

[0003] The purpose of this invention is to provide a telescopic slide rail fixing device with improved durability.

[0004] This invention relates to a telescopic slide rail fixing device, suitable for positioning a slide rail unit in a server rack. The telescopic slide rail fixing device includes a rear support unit, a front support unit, and a reinforcing structure. The rear support unit is suitable for installation on the rear side of the server rack and includes a first through-hole group. The first through-hole group has a plurality of first through holes arranged in the front-rear direction. The front support unit is suitable for installation on the front side of the server rack and the slide rail unit. The front support unit is movably disposed on the rear support unit, allowing the length of the telescopic slide rail fixing device in the front-rear direction to be adjusted to correspond to the dimensions of the server rack. The reinforcing structure is disposed on the rear support unit and extends along the front-rear direction, and is aligned with the first through-hole group in the vertical direction.

[0005] The telescopic slide rail fixing device of the present invention includes a rear support unit comprising two first through-hole groups. The first through-hole groups are arranged side-by-side in the vertical direction. The reinforcing structure is located between the first through-hole groups.

[0006] The telescopic slide rail fixing device of the present invention further includes a rear bracket suitable for installation on the rear side of the cabinet in the rear support unit. The rear bracket has a rear frame side plate extending along the front-rear direction, and two rear frame cross plates extending from the upper and lower sides of the rear frame side plate in the left-right direction toward the slide rail unit. The rear frame side plate and the rear frame cross plates define a rear frame groove into which the front support unit can be inserted in a slidable front-rear direction. A first set of through holes is formed at the connection points between the rear frame cross plates and the rear frame side plates. The reinforcing structure is located between the rear frame side plates and the front support unit.

[0007] The telescopic slide rail fixing device of the present invention further includes a rear support unit and an elastic element. The rear support rail is disposed on the front side of the rear bracket and adjacent to the first through hole group. The two opposite ends of the elastic element are respectively disposed on the rear support rail and the front support unit. The elastic element can elastically deform or return to its length when driven by the back-and-forth movement of the front support unit.

[0008] The telescopic slide rail fixing device of the present invention includes a rear support rail having a rear rail side plate extending along the front-rear direction and mounted on the rear frame side plate, and two rear rail cross plates extending from the upper and lower sides of the rear rail side plate respectively in the left-right direction toward the slide rail unit. The rear rail side plate and the rear rail cross plates define a rear rail groove communicating with the rear frame slide groove, and the rear rail groove and the rear frame slide groove together allow the front support unit to be inserted into it in a way that allows it to move back and forth.

[0009] The telescopic slide rail fixing device of the present invention includes a front support unit comprising a front bracket suitable for installation on the front side of the cabinet and the front side of the slide rail unit, and a front support rail suitable for installation on one of the left and right sides of the slide rail unit. The front support rail is movably inserted into the rear rail groove and the rear frame groove, and has a front rail side plate extending along the front-rear direction, and two front rail cross plates extending from the upper and lower sides of the front rail side plate in the left-right direction away from the slide rail unit. The front rail side plate and the front rail cross plates define an accommodating space for the reinforcing structure to be housed within.

[0010] The telescopic slide rail fixing device of the present invention includes a reinforcing structure comprising a reinforcing side plate extending along the front-rear direction and installed on the rear frame side plate, and two reinforcing horizontal plates extending from the upper and lower sides of the reinforcing side plate in the left-right direction toward the slide rail unit.

[0011] In the telescopic slide rail fixing device of the present invention, the reinforcing structure is riveted to the rear frame side plate of the rear support unit.

[0012] The telescopic slide rail fixing device of the present invention further includes two second through-hole groups formed at the connection between the front rail cross plate and the front rail side plate, adjacent to the first through-hole group. Each second through-hole group has a plurality of second through holes arranged in the front-rear direction.

[0013] The telescopic slide rail fixing device of the present invention has the reinforcing structure integrally formed with the rear support rail.

[0014] The beneficial effect of the present invention is that, through the design of combining the reinforcing structure with the rear support unit, the rear support unit can be structurally strengthened and less prone to deformation when the first through hole group is not blocked, thereby achieving the effect of improved durability.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] See Figure 1 This is one embodiment of the telescopic slide rail fixing device 100 of the present invention. For ease of explanation thereafter, the directional terms used to describe the telescopic slide rail fixing device 100 are defined according to the usage environment of the telescopic slide rail fixing device 100, i.e. Figure 1 The arrow in the forward-backward direction X points to the front side of the telescopic slide rail fixing device 100, and the opposite direction is the rear side; Figure 1The left-right arrow Y in the middle points to the right side of the telescopic slide rail fixing device 100, and the opposite direction is to the left side; Figure 1 The arrow pointing in the vertical direction Z points to the upper side of the telescopic slide rail fixing device 100, and the opposite direction is the lower side.

[0023] See Figure 1 and Figure 2 The telescopic slide rail fixing device 100 is suitable for positioning a slide rail unit 200 on one side of the left or right side of a rectangular cabinet (not shown). Figure 2 As shown, the slide rail unit 200 is, for example, a three-rail structure, including an outer rail 201 that is elongated and extends along the front-rear direction X, a middle rail 202 that is movable back-and-forth on the outer rail 201, and an inner rail 203 that is movable back-and-forth on the side of the middle rail 202 away from the outer rail 201. However, the slide rail unit can also be a two-rail structure (not shown) where the middle rail is omitted and the inner rail is installed on the outer rail, and is not limited to a three-rail structure. The inner rail 203 is suitable for connecting to one of the left or right sides of an object such as a server chassis or drawer that needs to be pulled forward or retracted back into the cabinet relative to the cabinet. In this embodiment, the telescopic slide rail fixing device 100 is exemplified by positioning the slide rail unit 200 on the left side of the cabinet. In this case, the inner rail 203 is located on the right side of the middle rail 202 and connected to the left side of the server chassis or the drawer.

[0024] See Figure 2 and Figure 3The telescopic slide rail fixing device 100 has its front and rear ends adapted for installation on the front and rear sides of one of the left and right sides of the cabinet, respectively. The overall length of the telescopic slide rail fixing device 100 in the front-rear direction X can be adjusted to accommodate cabinets with different lengths in the front-rear direction X. Specifically, the telescopic slide rail fixing device 100 includes a rear support unit 1, a front support unit 2 movably disposed on the rear support unit 1, and a reinforcing structure 3 disposed on the rear support unit 1. The rear support unit 1 is adapted for installation on the rear inner wall of the cabinet and includes two first through-hole groups 11. The first through-hole groups 11 are arranged side-by-side in the vertical direction Z. Each first through-hole group 11 has a plurality of first through holes 111 arranged in the front-rear direction X. The first through hole 111 penetrates the left and right sides and / or the top and bottom sides of the rear support unit 1, and is suitable for allowing gas to pass through as a heat dissipation hole. However, the first through hole 111 can also allow server wiring to pass through, and is not limited to a specific function. In addition, in some other embodiments, the rear support unit may only include a first through hole group, and the first through hole group is located on one of the top and bottom sides of the rear support unit, depending on the actual needs.

[0025] See Figure 2 , Figure 3 Furthermore, the rear support unit 1 includes a rear bracket 12, a rear support rail 13, and an elastic element 14. The rear bracket 12 has a rear frame side plate 121, two rear frame cross plates 122, a rear frame slide groove 123, and two rear connectors 124. The rear frame side plate 121 extends along the front-rear direction X, and the rear section of the rear frame side plate 121 extends toward the slide rail unit 200. The rear frame cross plates 122 extend from the upper and lower sides of the rear frame side plate 121 in the left-right direction Y toward the slide rail unit 200. The rear frame side plate 121 and the rear frame cross plates 122 define the rear frame slide groove 123. The first through hole group 11 is formed at the connection between the rear frame cross plates 122 and the rear frame side plate 121. The rear connectors 124 are arranged vertically and protrude rearward from the rear section of the rear frame side plate 121. The rear connector 124 is adapted to be detachably inserted into a hole on the rear side of the cabinet, so that the rear bracket 12 is installed on the rear side of the cabinet. The rear support rail 13 is disposed on the front side of the rear bracket 12 and adjacent to the first through hole group 11. The rear support rail 13 has a rear rail side plate 131 extending along the front-rear direction X and mounted on the rear frame side plate 121, two rear rail cross plates 132 extending from the upper and lower sides of the rear rail side plate 131 respectively in the left-right direction Y toward the slide rail unit 200, and a rear rail hook 133 disposed on the side of the rear rail side plate 131 adjacent to the slide rail unit 200 (see Figure 3 The rear rail side plate 131 and the rear rail cross plate 132 define a rear rail groove 134 that connects to the rear frame groove 123.

[0026] See Figures 3 to 6 The elastic element 14 is, for example, a tension spring, but not limited thereto; it can also be a compression spring or other object with elastic recovery function. The two opposite ends of the elastic element 14 are respectively disposed on the rear support rail 13 and the front support unit 2. The elastic element 14 can be driven by the forward and backward movement of the front support unit 2, as... Figure 6 The elastic deformation shown or as Figure 5 The length of the response shown.

[0027] See Figures 2 to 4 The front support unit 2 is suitable for installation on the front side of the cabinet, on the side of the outer rail 201 of the slide rail unit 200 away from the inner rail 203. Furthermore, the front support unit 2 is movably positioned on the side of the rear support unit 1 adjacent to the outer rail 201, allowing the length of the telescopic slide rail fixing device 100 in the front-rear direction X to be adjusted according to the size of the cabinet. Specifically, the front support unit 2 includes a front bracket 21 (see [reference needed]) suitable for installation on the front inner wall of the cabinet and the front side of the slide rail unit 200. Figure 2 The front bracket 21 has a front support rail 22 suitable for installation on one side of the left or right sides of the slide rail unit 200. The front section of the front bracket 21 extends away from the slide rail unit 200 and has two forward-protruding front connectors 211. The front connectors 211 are arranged vertically and are suitable for being detachably inserted into holes on the front side of the cabinet, so that the front bracket 21 is suitable for installation on the front side of the cabinet. The front support rail 22 is movably inserted into the rear rail groove 134 and the rear frame groove 123, and has a front rail side plate 221 extending in the front-rear direction X, two front rail cross plates 222 extending away from the slide rail unit 200 in the left-right direction Y from the upper and lower sides of the front rail side plate 221, and a front rail hook 223 disposed on the side of the front rail side plate 221 adjacent to the rear support unit 1. The front rail cross plate 222 is located between the rear frame cross plate 122 and the rear rail cross plate 132, and the front rail side plate 221 and the front rail cross plate 222 define an accommodating space 224. In this embodiment, the front rail hook 223 is used to hook the rear end of the elastic member 14, and the rear rail hook 133 is used to hook the front end of the elastic member 14, so that the elastic member 14 can be elastically deformed or return to its length by being driven by the front support unit 2.

[0028] See Figures 2 to 6Furthermore, the front support rail 22 also has two second through-hole groups 225 respectively formed at the connection between the front rail cross plate 222 and the front rail side plate 221 and adjacent to the first through-hole group 11. Each second through-hole group 225 has a plurality of second through holes 226 arranged in the front-rear direction X (five in example). The second through holes 226 penetrate the left and right sides and / or the upper and lower sides of the front support rail 22 and are used to connect to the first through hole 111 to allow gas or server lines to pass through the first through hole 111. When the elastic member 14 is in such a state... Figure 5 When the elastic element 14 is not stretched (i.e., it maintains its original length), the front support rail 22 protrudes beyond the rear support rail 13 by a specific length (i.e., the overall length of the telescopic slide rail fixing device 100 increases after the front support rail 22 moves backward), and the second through hole 226 is completely aligned with the first through hole 111. Figure 6 As shown, when the front support rail 22 is moved backward and the elastic member 14 is stretched (i.e., the elastic member 14 elastically deforms), the length of the front support rail 22 protruding from the rear support rail 13 is shortened compared to the specified length (i.e., the overall length of the telescopic slide rail fixing device 100 becomes shorter). At this time, the second through hole 226 partially aligns with the first through hole 111. The elastic member 14 provides a forward elastic restoring force to the front support rail 22. Then, the front support rail 22, driven by the elastic restoring force, applies force to the slide rail unit 200, thereby causing the front bracket 21 mounted on the slide rail unit 200 to press against the cabinet, thus completing the assembly action of the telescopic slide rail fixing device 100 positioning the slide rail unit 200 in the cabinet.

[0029] The reinforcing structure 3 is disposed on the side of the rear support unit 1 adjacent to the front support unit 2 and extends along the front-rear direction X, and is aligned with the first through-hole group 11 in the vertical direction Z. In other words, the reinforcing structure 3 fits against the rear support unit 1 and is located between the first through-hole group 11. In this way, the reinforcing structure 3 provides support force to the rear support unit 1 in the vertical direction Z and the horizontal direction Y, so that the rear support unit 1 is supported (structurally reinforced) without being obstructed by the first through-hole group 11, and is not easily twisted or deformed, thereby achieving the effect of improved durability. In this embodiment, the reinforcing structure 3 is, for example, formed by stamping and bending a metal sheet with a mold, and includes a reinforcing side plate 31 extending along the front-rear direction X and installed on the rear frame side plate 121, and two reinforcing horizontal plates 32 extending from the upper and lower sides of the reinforcing side plate 31 in the horizontal direction Y toward the slide rail unit 200. The reinforcing horizontal plates 32 abut against the front support rail 22 and are constrained by the front support rail 22 and are not easily deformed. Furthermore, the reinforcing structure 3 is riveted to the rear frame side plate 121 of the rear support unit 1, and is not easily detached.

[0030] Preferably, the reinforcing structure 3 is located between the rear frame side plate 121 and the front support unit 2, that is, the reinforcing structure 3 is disposed within the accommodating space 224 and the rear frame slide groove 123, so as to reduce the thickness of the telescopic slide rail fixing device 100 in the left-right direction Y. Preferably, the reinforcing structure 3 is integrally formed with the rear support rail 13 (not shown in the figure), which makes it more stable.

[0031] In summary, by combining the reinforcing structure 3 with the rear support unit 1, the rear support unit 1 can be structurally strengthened and less prone to deformation when the first through hole group 11 is not obstructed, thereby achieving the effect of improved durability. Therefore, the purpose of this invention can indeed be achieved.
