Description

Technical Field

[0001] This utility model relates to a slide rail device, and more particularly to a slide rail assembly device suitable for server chassis, which utilizes a middle rail lever and an inner rail lever to retract the inner rail and middle rail into the outer rail or pull out the inner rail and slide rail mechanism that extends into the middle rail. Background Technology

[0002] Slide rail products, typically used in server chassis, primarily utilize a drawer mounted to the chassis via a slide rail assembly. When the drawer is retracted into the chassis, a pressing gap is formed between the drawer's front panel and the chassis. This gap allows the user to press the drawer relative to the chassis, enabling it to open relative to the chassis via a push-to-open mechanism within the slide rail assembly. However, often unaware of this push-to-open function, users may unknowingly pull the slide rail (or drawer) forcefully when it is closed relative to the fixed rail (or chassis), opening it from the closed position. This method, which doesn't involve pressing, can damage components of the push-to-open mechanism, rendering the push-to-open function ineffective. Therefore, improvement is necessary.

[0003] In view of this, this utility model has developed a slide rail device based on years of experience, which can eliminate the shortcomings of existing products and improve the effect. Utility Model Content

[0004] Therefore, the main purpose of this utility model is to provide a slide rail device, which is an innovative slide rail assembly device. When the inner rail is retracted, the pusher of the middle rail is used to avoid the outer rail limiting block, so that the inner rail and the middle rail are retracted into the outer rail, or the pusher of the inner rail is used to make the inner rail avoid the middle rail limiting block, so as to pull out the slide rail mechanism that extends the inner rail into the middle rail.

[0005] To achieve the above objectives, the present invention employs the following technical means:

[0006] A slide rail device for connecting a server chassis, the slide rail device comprising:

[0007] An outer rail, a middle rail, and an inner rail are provided, wherein the middle rail is movably installed between the outer rail and the inner rail, and the outer rail, the middle rail, and the inner rail can be longitudinally displaced relative to each other. The middle rail has a channel to accommodate the inner rail.

[0008] Two outer rail limiting blocks are provided at one end of the outer rail, and an outer rail block is provided inside the track at the other end of the outer rail. The middle rail is restricted by the outer rail block and the two outer rail limiting blocks and cannot move back and forth. A middle rail lever is provided near the outer rail block end of the middle rail. After the middle rail lever is rotated, it can avoid the outer rail block and can retract the inner rail and the middle rail into the outer rail. An inner rail lever is provided in the middle of the inner rail track, and a middle rail limiting block is provided at one end of the middle rail. A slot is provided in the middle part of the inner rail lever. The slot can be locked by the middle rail limiting block. When the inner rail lever moves upward, the slot of the inner rail lever avoids the middle rail limiting block, so as to pull out the inner rail and extend into the middle rail.

[0009] Optionally, a center rail lever is provided with a center rail lever steel wire, which is stretched and rotated by the center rail lever steel wire.

[0010] Optionally, an inner rail lever is provided with an inner rail lever steel wire, which is stretched by the inner rail lever steel wire to move upward.

[0011] Optionally, at least one outer rail bead holder is provided inside the outer rail limit block of the outer rail. When the outer rail extends, the outer rail bead holder will extend synchronously with the outer rail.

[0012] The beneficial effects of this utility model are as follows:

[0013] When the slide rail device of this utility model retracts the inner rail, it uses the push of the middle rail lever to avoid the outer rail limit block, so that the inner rail and the middle rail are retracted into the outer rail, or pushes the inner rail lever to make the inner rail avoid the middle rail limit block, so that the inner rail is pulled out and extends into the middle rail.

[0038] 20. Screws Detailed Implementation

[0039] Please see Figures 1 to 3 The slide rail device 10 of this utility model includes an outer rail 11, a middle rail 12 and an inner rail 13. The middle rail 12 is movably installed between the outer rail 11 and the inner rail 13. The outer rail 11, the middle rail 12 and the inner rail 13 can be longitudinally displaced relative to each other. The middle rail 12 has a channel 120 to accommodate the inner rail 13. The side portions 111 and 112 of the outer rail 11 are fixed to the server chassis by at least one screw 20.

[0040] See also Figures 1 to 5Two outer rail limiting blocks 113 are arranged at the upper and lower ends of the outer rail 11 at one end. An outer rail stop 114 is located inside the track at the other end of the outer rail 11. The middle rail 12 cannot move forward or backward due to the constraints of the front and rear outer rail stops 114 and the two outer rail limiting blocks 113. An outer rail bead holder 115 is located inside the outer rail limiting blocks 113. When the outer rail 11 extends, the outer rail bead holder 115 extends synchronously with the outer rail 11. (See reference...) Figure 5 and Figure 6 A middle rail lever 121 is provided at the end of the middle rail 12 near the outer rail stop 114. A middle rail lever steel wire 122 is installed on the middle rail lever 121. The middle rail lever 121 is stretched and rotated by the middle rail lever steel wire 122 to avoid the outer rail stop 114. In this way, the inner rail 13 and the middle rail 12 can be drawn into the outer rail 11.

[0041] Cooperate Figure 4 As shown, an inner rail lever 131 is provided in the middle of the inner rail 13, and an inner rail lever steel wire 132 is installed on the inner rail lever 131. A middle rail limiting block 123 is provided at one end of the middle rail 12, and a slot 1311 is provided in the middle of the inner rail lever 131. Normally, the slot 1311 can be used to lock the middle rail limiting block 123. (See reference) Figure 7 When the inner rail lever steel wire 132 drives the inner rail lever 131 to move upward (as shown by the arrow), the slot 1311 of the inner rail lever 131 avoids the middle rail limit block 123, so that the inner rail 13 can be pulled out and inserted into the middle rail 12.

[0042] In summary, the slide rail device of this utility model utilizes the method of pushing the middle rail lever to avoid the outer rail limiting block, so that the inner rail and the middle rail are retracted into the outer rail, or pushing the inner rail lever to make the inner rail avoid the middle rail limiting block, so as to pull out the inner rail and extend into the middle rail.
