Description

Technical Field

[0001] This utility model belongs to the field of slide rails, specifically a slide rail assembly. Background Technology

[0002] The sliding rails commonly used in servers typically have a stop on the second rail. When the second rail extends along the first rail, it is temporarily locked to the first rail by the stop. When the third rail retracts into the second rail, the third rail pushes the stop to release the lock between the second and first rails. However, when the server is being repaired, the third rail is removed along with the server, which causes the second rail to be unable to retract into the first rail. Utility Model Content

Detailed Implementation

[0042] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0043] like Figures 1 to 6CThe slide rail assembly shown includes: a first rail 10, which has at least one positioning feature 11.

[0044] The second track 20 is displaceable relative to the first track 10, and the back of the second track 20 forms a concave surface 21, which faces the positioning feature 11.

[0045] The first stop 30 is mounted on the concave surface 21 and can correspond to the first side 111 of the positioning feature 11.

[0046] The operating member 40 is movably connected to the second rail 20, and is positioned within the concave surface 21, so that the operating member 40 is located on the side of the first stop member 30, as shown below. Figure 3A , Figure 4A and Figure 5A As shown, when the operating member 40 pushes the first stop 30 along the concave surface 21, the first stop 30 does not block the first side 111 of the positioning feature 11.

[0047] Figure 3B , Figure 4B and Figure 5B As shown, the second stop 50 and the elastic component 60 are mounted on the concave surface 21 and correspond to the second side 112 of the positioning feature 11. One end of the elastic component 60 is connected to the first stop 30, and the other end of the elastic component 60 is connected to the second stop 50, so that the elastic component 60 can provide elastic force to the first stop 30 and the second stop 50. In this embodiment, the elastic component 60 is a spring, but it is not limited thereto.

[0048] Figure 3C , Figure 5C As shown, the side end of the first stop 30 forms a first inclined surface 31, and the operating member 40 has a second inclined surface 401, which corresponds to the first inclined surface 31, but is not limited thereto.

[0049] In a further embodiment, the second rail 20 is provided with a first hole 22, a second hole 23 and a third hole 24, one end of the first stop member 30 forms a first stop portion 32, and one end of the second stop member 50 forms a second stop portion 51. The first stop portion 32 is displaceable relative to the first hole 22, the elastic component 60 is located in the second hole 23 and is displaceable, and the second stop portion 51 is displaceable relative to the third hole 24.

[0050] The first stop 32 is located in the first hole 22, and the second stop 51 is located in the third hole 24. The first hook 33 is formed by the other end of the first stop 30. The first hook 33 is located in the second hole 23 and is connected to one end of the elastic component 60. The second hook 52 is formed by the other end of the second stop 50. The second hook 52 is located in the second hole 23 and is connected to the other end of the elastic component 60. The first stop 32 and the second stop 51 limit the displacement of the first hole 22 and the third hole 24. They can also help the first stop 30 and the second stop 50 to reduce the impact and make precise displacement when swinging. In this way, the structure of the first stop 30 and the second stop 50 installed between the concave surfaces 21 is protected from damage, but this is not the only limitation.

[0051] like Figure 3D , Figure 5D As shown, the second track 20 is provided with a first limiting feature 26, and the operating member 40 has an operating part 41. The operating part 41 is provided with a second limiting feature 411. The second limiting feature 411 can be displaced relative to the first limiting feature 26. The first limiting feature 26 is located within the second limiting feature 411. The first limiting feature 26 can be a first limiting hole 261, a second limiting hole 262, or a combination of the first limiting hole 261 and the second limiting hole 262. A first limiting surface 2611 is formed on one side of the first limiting hole 261, and a second limiting surface 2621 is formed on one side of the second limiting hole 262. The second limiting feature 411 is either a first limiting member 411A or a second limiting member 41. 1B or a combination of the first limiting member 411A and the second limiting member 411B, wherein the first limiting member 411A has a first body A1, a rib A2 extending to the side of the first body A1, and a first limiting body A3 extending to the front end of the first body A1, and the second limiting member 411B has a second body B1 and a second limiting body B2 extending to the front end of the second body B1, such that the first limiting body A3 abuts against the first limiting surface 2611 and the second limiting body B2 is engaged with the second limiting surface 2621, or the first limiting body A3 is engaged with the first limiting surface 2611 and the second limiting body B2 abuts against the second limiting surface 2621, but not limited thereto.

[0052] In a further embodiment, the second rail 20 is provided with an opening 27, and the side of the opening 27 is provided with a first limiting piece 271 with a necking structure, and the operating member 40 is provided with at least one second limiting piece 42 with an arch bridge structure, the second limiting piece 42 straddling the first limiting piece 271, but not limited thereto.

[0053] like Figure 1 , Figure 2The first track 10 shown includes a positioning seat 12 and a positioning hole 13, and is provided with at least one positioning feature 11. The positioning feature 11 is formed by bending on the positioning seat 12. The positioning feature 11 is inserted into the positioning hole 13 and extends to the front side of the first track 10. The positioning seat 12 is fixed to the back side of the first track 10. That is, in this embodiment, the positioning feature 11 is a bent part that extends from the positioning seat 12 through the positioning hole 13 to the front side of the first track 10, but it is not limited thereto.

[0054] Such as 3A, Figure 5A As shown, the first track 10 includes: a starting member 14, and the first stop member 30 has a starting surface 34. When the starting surface 34 abuts against the starting member 14, the first stop member 30 is activated, but not limited thereto.

[0055] like Figure 3B , Figure 5B As shown, a first locking groove 35 is formed on the other side of the first stop 30, which corresponds to the first side 111 of the positioning feature 11, and a second locking groove 54 is formed on the other side of the second stop 50, which corresponds to the second side 112 of the positioning feature 11, but is not limited thereto.

[0056] like Figure 5E , Figure 5F As shown, there can be two positioning features 11. One positioning feature 11 is located at the front section of the first rail 10, allowing the second rail 20 to extend from the first rail 10. When the first stop 30 does not block the first side 111 of the positioning feature 11 located at the front section of the first rail 10, the second rail 20 can be retracted. The other positioning feature 11 is located at the rear section of the first rail 10. When the first stop 30 blocks the first side 111 of the positioning feature 11 located at the rear section of the first rail 10, the second rail 20 can be retracted to a predetermined position on the first rail 10, but this is not a limitation.

[0057] like Figure 6A , Figure 6B and Figure 6C As shown, the slide rail assembly also includes a third rail 70, which is displaceable relative to the second rail 20. The side end of the second stop 50 forms a pushing part 53, and the second rail 20 is provided with a fourth hole 25. The pushing part 53 extends through the fourth hole 25 to the front of the second rail 20, so that the pushing part 53 can be pushed by the third rail 70 when the third rail 70 is displaced.

[0058] Based on the above configuration, the operating member 40 is movably connected to the second rail 20, allowing the operating member 40 to push the first stop 30 along the concave surface 21 of the second rail 20. Both the operating member 40 and the first stop 30 are hidden within the concave surface 21 of the second rail 20, allowing the operating member 40 to directly push the first stop 30. This eliminates the linkage between the operating member 40 and the first stop 30, enabling the operator to easily release the locking state between the second rail 20 and the first rail 10 using the operating member 40. It also reduces manufacturing costs, prevents linkage failures, and facilitates thinner slide rails. Furthermore, the first rail 10 can be an outer frame, the second rail 20 can be a middle frame, and the third rail 70 can be an inner frame.

[0059] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
