Description

Technical Field

[0001] The utility model relates to a slide rail fixing device, in particular to a telescopic slide rail fixing device. Background Art

[0002] The existing telescopic slide rail fixture is suitable for positioning a slide rail assembly in a server cabinet. The slide rail assembly is suitable for carrying a server and allowing the server to move forward and backward relative to the server cabinet. The telescopic slide rail fixture includes at least two components that can move forward and backward relative to each other. The design that the at least two components can move forward and backward relative to each other allows the overall length of the telescopic slide rail fixture to be adjusted to correspond to server cabinets of different sizes. However, when at least a portion of the at least two components overlap and the overall length of the telescopic slide rail fixture is shortened, the overall thickness of the telescopic slide rail fixture in the overlapping portion will increase, resulting in the heat energy generated by the server during operation being blocked by the telescopic slide rail fixture, resulting in poor heat dissipation of the server. In order to solve the problem of poor heat dissipation of the server, a plurality of heat dissipation holes are usually provided on the telescopic slide rail fixture, but this also leads to the problem that the telescopic slide rail fixture will be deformed when the server carried by the slide rail assembly is too heavy.

For the convenience of explanation, the directional terms of the telescopic rail fixing device 100 are defined by the use environment of the telescopic rail fixing device 100, that is, Figure 1 An arrow in the front-to-back direction X in FIG. 1 points to the front side of the telescopic rail fixing device 100 , and an arrow in the opposite direction points to the rear side; Figure 1 An arrow in the left-right direction Y in FIG. 1 points to the right side of the telescopic rail fixing device 100 , and the reverse direction is the left side; Figure 1 An arrow in the up-down direction Z in FIG. 1 points to the upper side of the telescopic slide rail fixing device 100 , and the opposite direction points to 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 of the left and right sides of a rectangular cabinet (not shown). Figure 2 As shown, the slide rail unit 200 is, for example, a three-rail structure and includes an outer rail 201 that is long and extends along the front-to-back direction X, a middle rail 202 that can be mounted on the outer rail 201 and can be moved back and forth, and an inner rail 203 that can be mounted on the side of the middle rail 202 away from the outer rail 201 and can be moved back and forth. However, the slide rail unit can also be a two-rail structure (not shown) in which the middle rail is omitted and the inner rail is mounted 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 and right sides of an object such as a server chassis or a drawer that needs to be pulled forward or retracted backward relative to the cabinet. In this embodiment, the telescopic slide rail fixing device 100 is based on an example of 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 is connected to the left side of the server chassis or the drawer.

[0024] See Figure 2 and Figure 3, the front and rear ends of the telescopic slide rail fixing device 100 are respectively suitable for installation on the front and rear sides of one of the left and right sides of the cabinet, and the overall length of the telescopic slide rail fixing device 100 in the front-to-back direction X can be adjusted to correspond to the installation and use of the cabinets with different lengths in the front-to-back direction X. In detail, the telescopic slide rail fixing device 100 includes a rear support unit 1, a front support unit 2 that can be moved forward and backward on the rear support unit 1, and a reinforcement structure 3 provided on the rear support unit 1. The rear support unit 1 is suitable 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 respectively arranged in parallel in the up-down direction Z. Each of the first through hole groups 11 has a plurality of first through holes 111 arranged in the front-to-back direction X. The first through holes 111 extend through the left and right sides and / or the top and bottom sides of the rear support unit 1 and are suitable for allowing air to pass through, thereby serving as heat dissipation holes. However, the first through holes 111 can also be used to pass server wiring, and are not limited to a specific function. In other embodiments, the rear support unit may include only one 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 actual needs.

[0025] See Figure 2 、 Figure 3 Specifically, the rear support unit 1 includes a rear bracket 12, a rear support rail 13, and an elastic member 14. The rear bracket 12 has a rear frame side plate 121, two rear frame transverse plates 122, a rear frame slide groove 123, and two rear joints 124. The rear frame side plate 121 extends along the front-to-back direction X, and the rear section of the rear frame side plate 121 extends toward the slide rail unit 200. The rear frame transverse 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 transverse plate 122 define the rear frame slide groove 123. The first through hole group 11 is formed at the connection between the rear frame transverse plate 122 and the rear frame side plate 121. The rear joints 124 are arranged in upper and lower positions and protrude rearward from the rear section of the rear frame side plate 121. The rear joint 124 is adapted to be detachably inserted into the hole on the rear side of the cabinet so that the rear bracket 12 is mounted on the rear side of the cabinet. The rear support rail 13 is provided on the front side of the rear bracket 12 and adjacent to the first through hole group 11. The rear support rail 13 comprises a rear rail side plate 131 extending along the front-to-back 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 in the left-right direction Y toward the direction of the slide rail unit 200, and a rear rail hook 133 (see FIG. 1 ) provided on the side of the rear rail side plate 131 adjacent to the slide rail unit 200. Figure 3 The rear rail side plate 131 and the rear rail cross plate 132 define a rear rail slide groove 134 that is connected to the rear frame slide groove 123 .

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

[0027] See Figures 2 to 4 The front support unit 2 is adapted to be installed on the front side of the cabinet and on the side of the outer rail 201 of the slide rail unit 200 away from the inner rail 203. The front support unit 2 is arranged on the side of the rear support unit 1 adjacent to the outer rail 201 so as to be movable forward and backward, so that the length of the telescopic slide rail fixing device 100 in the front-to-back direction X can be adjusted according to the size of the cabinet. Specifically, the front support unit 2 includes a front bracket 21 (see FIG. 1 ) adapted to be installed on the front inner wall of the cabinet and the front side of the slide rail unit 200. Figure 2 ), and a front support rail 22 suitable for installation on one of the left and right sides of the slide rail unit 200. The front section of the front bracket 21 extends in a direction away from the slide rail unit 200 and is provided with two front joints 211 protruding forward. The front joints 211 are arranged in an upper and lower manner and are suitable for being detachably inserted into the 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 can be inserted into the rear rail guide groove 134 and the rear frame guide groove 123 so as to move forward and backward, and has a front rail side plate 221 extending along the front-to-back direction X, two front rail cross plates 222 extending from the upper and lower sides of the front rail side plate 221 in the left-right direction Y in a direction away from the slide rail unit 200, and a front rail hook 223 provided on one 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 plates 221 and the front rail cross plate 222 define an accommodation space 224. In this embodiment, the front rail hook 223 is hooked to the rear end of the elastic member 14, and the rear rail hook 133 is hooked to the front end of the elastic member 14, so that the elastic member 14 can be elastically deformed or restored to its original length by the front support unit 2.

[0028] See Figures 2 to 6, further, the front support rail 22 also has two second through hole groups 225 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 (five for example) arranged in the front-to-back direction X. The second through holes 226 pass through 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 for the gas or service line leading to the first through hole 111 to pass through. When the elastic member 14 is in a position as shown Figure 5 When the front support rail 22 is not stretched (i.e., the elastic member 14 maintains its original length), the front support rail 22 protrudes from the rear support rail 13 by a specific length (i.e., the overall length of the telescopic slide rail fixing device 100 becomes longer 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 operated to move rearward, stretching the elastic member 14 (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 fixture 100 is shortened). At this time, the second through hole 226 is partially aligned with the first through hole 111. The elastic member 14 also provides the front support rail 22 with a forward elastic restoring force. Subsequently, the front support rail 22 is driven by the elastic restoring force to apply force to the slide rail unit 200, thereby driving the front bracket 21 mounted on the slide rail unit 200 to press against the cabinet, completing the assembly of the telescopic slide rail fixture 100 to position the slide rail unit 200 in the cabinet.

[0029] The reinforcement structure 3 is disposed on a side of the rear support unit 1 adjacent to the front support unit 2 and extends along the front-to-back direction X. It is aligned with the first through-hole group 11 in the top-to-bottom direction Z. In other words, the reinforcement structure 3 is attached to the rear support unit 1 and located between the first through-hole group 11. Thus, the reinforcement structure 3 provides support to the rear support unit 1 in the top-to-bottom direction Z and the left-to-right direction Y. This supports the rear support unit 1 (structurally reinforced) while not obstructed by the first through-hole group 11, thereby preventing it from twisting and deforming, thereby improving durability. In this embodiment, the reinforcement structure 3 is formed, for example, from a metal sheet through stamping and bending. The reinforcement structure 3 includes a reinforcement side panel 31 extending along the front-to-back direction X and mounted to the rear frame side panel 121, and two reinforcement cross panels 32 extending from the upper and lower sides of the reinforcement side panel 31 in the left-to-right direction Y toward the slide rail unit 200. The reinforcement cross panels 32 abut against the front support rail 22 and are restrained by the front support rail 22 to prevent deformation. In addition, the reinforcement structure 3 is riveted to the rear frame side plate 121 of the rear support unit 1 and is not easy to fall off.

[0030] Preferably, the reinforcement structure 3 is located between the rear frame side plate 121 and the front support unit 2, that is, the reinforcement structure 3 is disposed within the accommodating space 224 and the rear frame slide groove 123, thereby reducing the thickness of the telescopic slide rail fixing device 100 in the left-right direction Y. Preferably, the reinforcement structure 3 is integrally formed with the rear support rail 13 (not shown), thereby providing greater stability.

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