Technical Field

[0001] This utility model relates to a guide rail assembly that integrates reinforcing members or fasteners to the rail components, and can be applied to server chassis or drawers, as well as to servers or furniture. Background Technology

[0002] With the mature development of the computer industry and cloud technology, the demand for electronic data access is increasing, especially in artificial intelligence (AI), such as ChatGPT. To meet the massive information access needs, the current server equipment structure consists of multiple server chassis within a server rack. The server chassis and the server rack are connected by a guide rail structure. For example, each side of the server chassis has a first guide rail, and each side of the server rack has a second guide rail relative to the first guide rail, allowing the first guide rail to move on the second guide rail. Summary of the Invention

[0003] The main objective of this utility model is to provide a guide rail assembly in which the third rail is combined with or integrally formed with the first rail, so that the first rail, the reinforcing member and the third rail form a strong lateral structure, thereby effectively integrating the reinforcing member into the rail component.

[0004] Another objective of this utility model is to provide a guide rail assembly in which the fastener has a limiting part and a fastening part. The fastener is arranged on a third rail and the third rail has a hole, so that the limiting part passes through the hole to activate the fastening part, thereby effectively integrating the fastener to the rail.

[0005] To achieve the above objectives, the technical means adopted by this utility model include: a first rail; a reinforcing member disposed on the first rail; a second rail movably connected to the first rail; a third rail, which is combined with or integrally formed with the first rail, so that the first rail, the reinforcing member and the third rail form a strong lateral structure; and a fourth rail movably connected to the third rail.

[0006] As described above, the reinforcing member has a surface with a gap between the surface and the second rail, and the reinforcing member increases its lateral thickness toward the second rail with the gap as the boundary.

[0007] As described above, the reinforcing member has a first segment and a second segment, and the first rail and the third rail have an overlapping segment. When the first rail and the third rail are unfolded together at a predetermined position on the second rail, the second segment, the rear segment of the second rail, and the overlapping segment correspond to each other.

[0008] To achieve the above objectives, the present invention employs the following technical means: a first rail, the first rail having a receiving space; a fastener, the fastener being located in the receiving space, and the fastener having a limiting part and a fastening part; a second rail, the second rail being movably connected to the first rail; a third rail, the third rail being combined with or integrally formed with the first rail, and the fastener being arranged on the third rail and the third rail having a hole corresponding to the receiving space, the limiting part passing through the receiving space to the hole, when the limiting part is displaced within the hole to a first state, the fastening part facing the first position, or when the limiting part is displaced within the hole to a second state, the fastening part facing the second position; and a fourth rail, the fourth rail being movably connected to the third rail.

[0009] As described above, the fourth track is provided with a guide member, which is positioned relative to the limiting portion. When the guide member guides the limiting portion in a first state, the buckle faces a first position; or when the guide member guides the limiting portion in a second state, the buckle faces a second position.

[0010] As described above, when the limiting part is in the first state and the buckle is facing the first position, the limiting part is fixed to the guide, causing the first rail, the third rail and the fourth rail to unfold together on the second rail.

[0011] As described above, the second rail has a buckle feature. When the buckle is facing the second position and the buckle feature is engaged, the limiting part is in the second state and the limiting part is released from the guide, causing the fourth rail to release from the third rail.

[0012] As described above, when the fourth rail is retracted into the third rail, the guide member contacts the limiting part, causing the limiting part to move from the second state to the first state and the buckle to move from the second position toward the first position. The buckle disengages from the buckle feature, causing the third rail, the first rail, and the fourth rail to retract together into the second rail.

[0013] As described above, it may also include an elastic element, one end of which is connected to the first rail, and the other end of which is connected to the fastener.

[0014] To achieve the above objectives, the present invention employs the following technical means: a fastener having a limiting part and a fastening part; a third rail, the fastener being arranged on the third rail and the third rail having a hole through which the limiting part passes; when the limiting part is displaced within the hole to a first state, the fastening part faces the first position, or when the limiting part is displaced within the hole to a second state, the fastening part faces the second position; and a fourth rail movably connected to the third rail, and the fourth rail having a guide member having... A first guide piece and a second guide piece corresponding to the first guide piece are provided, and a guide channel is formed between the first guide piece and the second guide piece. The limiting part has a first limiting body and a second limiting body protruding from the first limiting body. The first limiting body is located on the hole. When the second limiting body passes through the guide channel with the first guide piece, the limiting part is in a first state and the fastening part faces the first position. Or when the second limiting body passes through the guide channel with the second guide piece, the limiting part is in a second state and the fastening part faces the second position.

[0106] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0107] Example

[0108] Please see Figures 1 to 21 As shown, this utility model is a guide rail assembly, including: a first rail 10; a reinforcing member 20, the reinforcing member 20 being disposed on the first rail 10; a second rail 30, the second rail 30 being movably connected to the first rail 10, the first rail 10 and the second rail 30 forming a first guide rail A; a third rail 40, the third rail 40 being mutually combined or integrally formed with the first rail 10, so that the first rail 10, the reinforcing member 20 and the third rail 40 form a strong lateral structure B; a fourth rail 50, the fourth rail 50 being movably connected to the third rail 40, the third rail 40 and the fourth rail 50 forming a second guide rail C. Therefore, the parallel combination of the first guide rail A and the second guide rail C forms a parallel guide rail, and the first rail 10 and the third rail 40 are the outer frame, and the second rail 30 and the fourth rail 50 are the inner frame.

[0109] Continuing from the above, the first track 10 has a first longitudinal wall 101, and a first transverse wall 102 and a second transverse wall 103 extend from both sides of the first longitudinal wall 101, respectively. The first longitudinal wall 101, the first transverse wall 102 and the second transverse wall 103 form a first channel A1. The third track 40 has a second longitudinal wall 401, and a third transverse wall 402 and a fourth transverse wall 403 extend from both sides of the second longitudinal wall 401, respectively. The second longitudinal wall 401, the third transverse wall 402 and the fourth transverse wall 403 form a second channel C1. The first longitudinal wall 101 and the second longitudinal wall 401 are combined with each other or integrally formed. Therefore, the first channel A1 and the second channel C1 form a dual channel. The second track 30 can move in the first channel A1 and the fourth track 50 can move in the second channel C1.

[0110] Figure 3As shown, the reinforcing member 20 has a surface 21, and a gap H is provided between the surface 21 and the second rail 30. The reinforcing member 20 increases its lateral thickness T towards the second rail 30 with the gap H as the boundary. Therefore, the overall height E of the first guide rail A and the second guide rail C can be reduced simultaneously, and the strength can be increased simultaneously, making it easier to install in a confined space. In this embodiment, the reinforcing member 20 can be multiple sections, a single piece, stacked, or self-formed, all within a uniform range. The second rail 30 is provided with a retaining wall 33, which can be a transverse wall or a predetermined feature.

[0111] Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the first rail 10 is provided with a receiving space 11, forming a limiting groove 12 within the first rail 10; a fastener 60 is located in the receiving space 11, and the fastener 60 has a limiting part 61 and a fastening part 62. The limiting part 61 has a first limiting body 611 and a second limiting body 612 protruding from the first limiting body 611. The fastener 60 is arranged on the third rail 40, and the third rail 40 is provided with a hole 41. The hole 41 corresponds to the receiving space 11, and the limiting part 61 passes through the receiving space 11 to the hole 41, with the first limiting body 611 positioned on the hole 41. The hole 41 is an elongated hole or an arc hole, and the hole 41 has a first inner edge surface 411 and a second inner edge surface 412 corresponding to the first inner edge surface 411. In this embodiment... In this fastener 60, a pivot member 63 and a first pivot hole 64 are provided. The third rail 40 is provided with a second pivot hole 42. The pivot member 63 passes through the first pivot hole 64 to the second pivot hole 42, so that the limiting part 61 can swing within the hole 41. The limiting groove 12 includes a guide surface 121, a first limiting surface 122 and a second limiting surface 123. The guide surface 121 has a flange 1211. The fastener 60 includes a first side surface 65, a first swing surface 66 and a second swing surface 67. The first side surface 65 is guided in different directions on the guide surface 121 by the flange 1211, so that the first swing surface 66 swings toward the first limiting surface 122 or the second swing surface 67 swings toward the second limiting surface 123. The fastener 60 includes a pivot hole 68 and the limiting part 61 includes a pivot body 613. The pivot body 613 passes through the hole 41, and the pivot hole 68 is fitted onto the pivot body 613. The first limiting body 611 and the second limiting body 612 are located on one side of the limiting part 61, while the pivot body 613 is located on the other side of the limiting part 61.

[0112] Figure 8As shown, the fourth track 50 is provided with a guide member 70. The guide member 70 is relative to the limiting part 61. The guide member 70 has a first guide piece 71 and a second guide piece 72 corresponding to the first guide piece 71. A guide channel G is formed between the first guide piece 71 and the second guide piece 72. Further, the first guide piece 71 has a bend to form a flat wall 711 and a first inclined wall 712 connecting the flat wall 711, and the second guide piece 72 has a bend to form a curved wall 721 and a second inclined wall 722 connecting the curved wall 721.

[0113] Figure 9 , Figure 10 , Figure 11 As shown, the first rail 10, the third rail 40, and the fourth rail 50 have not yet been simultaneously deployed to the second rail 30. Therefore, when the limiting part 61 moves to the first state S1 within the hole 41, the fastening part 62 faces the first position P1. The guide member 70, relative to the limiting part 61, guides the limiting part 61 to the first state S1, and the fastening part 62 faces the first position P1. Further, when the second limiting body 612 passes through the guide channel G according to the first guide piece 71, then the... When the limiting part 61 is in the first state S1 and the fastening part 62 is facing the first position P1, the second limiting body 612 contacts the first inclined wall 712 to the flat wall 711, and the second limiting body 612 gradually moves away from the first inner edge surface 411, so that the second limiting body 612 is pressed against the flat wall 711. Conversely, when the second limiting body 612 contacts the flat wall 711 to the first inclined wall 712, the second limiting body 612 gradually moves towards the first inner edge surface 411, so that the second limiting body 612 is not pressed against the flat wall 711.

[0114] Please refer to the following: Figure 2 , Figure 3 As shown, and in conjunction with Figure 12 , Figure 13 As shown, when the limiting part 61 is in the first state S1 and the buckle part 62 is facing the first position P1, the limiting part 61 is fixed to the guide member 70. To further explain, when the first rail 10, the third rail 40 and the fourth rail 50 are not simultaneously unfolded on the second rail 30, the barrier wall 33 blocks the buckle part 62, and the second inclined wall 722 of the second guide piece 72 contacts the second limiting body 612. Therefore, when the fourth rail 50 is pulled, the third rail 40 can be driven, and the third rail 40 and the fourth rail 50 can be unfolded together synchronously, so that the first rail 10, the third rail 40 and the fourth rail 50 are unfolded together synchronously on the second rail 30.

[0115] Figure 14 , Figure 15 , Figure 16 As shown, the second rail 30 has a fastening feature 31, which can be a fastening hole or a fastening body. When the fastening part 62 is facing the second position P2 and fastens the fastening feature 31, the limiting part 61 is in the second state S2 and is released from the guide member 70, causing the fourth rail 50 to be released from the synchronization between the third rail 40 and the fourth rail 50 unfolded on the third rail 40. In this way, when the limiting part 61 is displaced within the hole 41 to the second state S2, the fastening part 62 is facing the second position P2, and the guide member 70 is relative to the limiting part 61. When the guide member 70 guides the limiting part 61 in the second state S2, the fastening part 62 is facing the second position P2. To further explain at the second position P2, when the second limiting body 612 passes through the guide channel G via the second guide piece 72, the limiting part 61 is in the second state S2 and the fastening part 62 faces the second position P2, so that the second limiting body 612 contacts the second inclined wall 722 to the curved wall 721, and the second limiting body 612 gradually moves away from the second inner edge surface 412, so that the second limiting body 612 is pressed against by the curved wall 721. Conversely, when the second limiting body 612 contacts the curved wall 721 to the second inclined wall 722, the second limiting body 612 gradually moves towards the second inner edge surface 412, so that the second limiting body 612 is not pressed against by the curved wall 721.

[0116] Figure 17 , Figure 18 , Figure 19 , Figure 20 As shown, the reinforcing member 20 has a first segment 22 and a second segment 23, and the first rail 10 and the third rail 40 have an overlapping segment L. When the first rail 10 and the third rail 40 are unfolded together at a predetermined position on the second rail 30, the second segment 23, the rear segment of the second rail 30, and the overlapping segment L correspond to each other. To further explain, when the entire guide rail is fully unfolded, the rear segment 501 of the fourth rail 50 extends beyond the rear segment 301 of the second rail 30 by a distance D, and the first segment 22 of the reinforcing member 20 is located at a position that does not correspond to the fourth rail 50. Only by the second segment 23 of the reinforcing member 20 being located at a predetermined distance D1 corresponding to the second rail 30 can the entire guide rail have strength and not sag.

[0117] Continuing from the above, when the fourth rail 50 retracts into the third rail 40, the guide member 70 contacts the limiting part 61. To further explain, firstly, the first inclined wall 712 of the first guide piece 71 contacts the second limiting body 612, and then the flat wall 711 of the first guide piece 71 presses against the second limiting body 612, causing the limiting part 61 to move from the second state S2 to the first state S1, and the buckle 62 to move from the second position P2 towards the first position P1. The buckle 62 disengages from the buckle feature 31, causing the first rail 10, the third rail 40, and the fourth rail 50 to retract together into the second rail 30, cooperating with the baffle wall 33 to block the buckle 62. Please refer to [further details omitted]. Figure 2 , Figure 3 As shown. In addition, the second rail 30 is provided with a first stop 32 and the third rail 40 is provided with a second stop 43, so that the fourth rail 50 is retracted to the third rail 40 and limited by the second stop 43, and the first rail 10 is retracted to the second rail 30 and limited by the first stop 32.

[0118] Figure 21 As shown, it also includes an elastic element 80. One end of the elastic element 80 is connected to the first rail 10, and the other end of the elastic element 80 is connected to the fastener 60. In this embodiment, the second limiting surface 123 has a protrusion 1231 and the fastener 62 has a lead hole 621. The elastic element 80 is a metal wire. One end of the metal wire passes through the lead hole 621 and is bent and fixed, while the other end of the metal wire abuts against the protrusion 1231, so that the fastener 60 has elasticity.

[0119] Based on this configuration, the second rail 30 can be combined with a large drawer, while the fourth rail 50 can be combined with a small drawer, thereby enhancing the functionality of the small drawer being able to be folded into or unfolded into the large drawer.

[0120] Figures 1 to 21 As shown, a plurality of fasteners I are used to fix each of the components. Each of the fasteners I can be a screw or rivet, or each of the components can be directly formed on the rails without fasteners I. Each of the components is on the rails as described above, and will not be described in detail.
