Once the fastening state between the fastener 44 and the mounting seat 46 is released, As shown in FIG. 2 , the second rail 32 can be popped up a distance relative to the second rail 32 relative to the first rail 30 by the elastic force generated by the elastic member 42 and displaced to the outside of the frame 20 to facilitate a case. 24 installation, as shown in Figure 8.

As shown in FIGS. 6 and 7 , the present invention further includes a guide seat 48 disposed at the front end of the second rail 32 . In a preferred embodiment, the guide seat 48 is integrally formed with the second rail 32 . The guide seat 48 has a first guide section 50 and a second guide section 52, the first guide section 50 and the second guide section 52 jointly define an inlet 54, an outlet 56 and a channel 58 Located between the inlet 54 and the outlet 56 , wherein the inlet 54 , the outlet 56 and the channel 58 are located in the same direction. In addition, one of the first guiding section 50 and the second guiding section 52 located at the entrance 54 of the guiding seat 48 has a guiding slope 60 , so that the width X1 of the entrance 54 is greater than the width X2 of the channel 58 . Preferably, it further includes a third guiding section 53 located above the first guiding section 50, for example, the third guiding section 53 extends from above the first guiding section 50 and bends outward at an angle , so as to conveniently guide the chassis 24 to be placed on the front end of the second rail 32 from above the third guide section 53 from top to bottom, and its related configuration will be described in detail later.

Referring again to FIG. 4 , in a preferred embodiment, the present invention further includes a stopper 62 movably mounted on the second rail 32 , and a part of the stopper 62 is located in the channel 58 of the guide seat 48 .

FIG. 8 and FIG. 9 show the installation relationship between the chassis 24 and the pair of slide rail assemblies 22 . Wherein, a plurality of mounting parts 64 are disposed on both sides of the chassis 24 .

As shown in FIG. 10 , there is a first transverse width W1 between the side wall 34 and the bottom wall 36 of the second rail 32 , and there is a gap between the entrance 54 of the guide seat 48 and the bottom wall 36 of the second rail 32 . There is a second transverse width W2, and there is a third transverse width W3 between each mounting member 64 of the chassis 24 and the bottom wall 36 of the second rail 32, and the third transverse width W3 is between the first transverse width between the width W1 and the second lateral width W2. In addition, the second lateral width W2 is smaller than the first lateral width W1.

As shown in Figures 10 and 11, in a preferred embodiment, the front end of the first rail 30 of the present invention has a protruding feature 66 (as shown in Figure 6) towards the side wall 34 of the second rail 32, so that When the second rail 32 is displaced to the outside of the frame 20 relative to the first rail 30, the second rail 32 can respond to the protruding feature 64 of the first rail 30 and deflect at an angle, so that the second rail 32 can be as close as possible. Combine the chassis 24 to increase the introduction between the plurality of mounting parts 64 of the chassis 24 and the guide seat 48 .

According to the above-mentioned configuration, when the chassis 24 is to be installed on the frame 20, as shown in FIGS. The elastic member 42 is ejected relative to the first rail 30 to move out of the frame 20 .

Next, as shown in FIGS. 12 to 15 , the user can first abut a part of the bottom 25 of the chassis 24 against the bottom wall 36 of the second rail 32 , and then push the chassis 24 into the rack 20 , in this process, through the inlet 54 of the guide seat 48, the plurality of mounting parts 64 of the chassis 24 can be guided one by one through the channel 58 and the outlet 56 of the guide seat 48, so that the chassis 24 is installed on the machine In the frame 20, the chassis 24 can be stably supported through the second rail 32. Even if the chassis 24 leans against the front end of the second rail 32 and there is a slight misalignment during installation, the entrance 54 of the guide seat 48 can also be used to guide the entry of the mounting piece 64 on the chassis 24. Position, that is to say, the present invention can guide the installation part 64 through the guide slope 60 (as shown in FIG. 7 ), so that the chassis 24 can be quickly and correctly installed on the second rail 32 .

In detail, when the plurality of mounting parts 64 of the chassis 24 pass through the channel 58 of the guide seat 48, the stopper 62 will be further pushed. In a preferred embodiment, refer to FIG. 15, the stopper 62 of the present invention There is an abutment feature 68, and the stopper 62 can be operated or pushed away from the passage 58 of the guide seat 48 to abut against the passage 58 of the guide seat 48 by means of the abutment feature 68. P, until the last installation piece 64 of the plurality of installation pieces 64 of the chassis 24 passes through the outlet 56 of the guide seat 48 , the stopper 62 can be manually operated to leave the abutting position P.

In a preferred embodiment, it can also be designed to automatically release the blocking member 62 from the resting position. Please refer to FIG. The stopper 62 at the position P, and one of the release feature 70 and the stopper 62 has a slope 72, as shown in Figure 16 and Figure 17, when the second rail 32 is retracted relative to the first rail 30, The blocking member 62 can be pushed away from the abutting position P by means of the slope 72 to return to the initial position, as shown in FIG. 18 .

In other words, when the blocking member 62 is pushed away from the abutting position P, the blocking member 62 will freely swing back to the channel 58 of the guiding seat 48 to block the last mounting member 64 of the chassis 24 .

On the other hand, when the cabinet 24 is to be removed from the frame 20, the blocking member 62 is also operable to leave the channel 58 of the guide seat 48, so that the cabinet 24 can be detached from the second rail 32 , so that the chassis 24 can also be easily removed from the rack 20 .

It is worth mentioning that, FIG. 19 shows a fourth lateral width W4 defined between the sidewalls 34 of the second rail 32 of the pair of slide rail assemblies 22, the first rail 32 of the pair of slide rail assemblies 22 A fifth transverse width W5 is defined between the three guide segments 53, wherein the fifth transverse width W5 is greater than the fourth transverse width W4, and the chassis 24 has a sixth transverse width W6 slightly smaller than the fourth transverse width W4 . With this configuration, when the user places and installs the bottom 25 of the chassis 24 toward the front end of the second rail 32 of the pair of slide rail assemblies 22 from top to bottom, through the third guide section 53 of the second rail 32 It can conveniently and accurately guide the front end of the cabinet 24 to be placed on the bottom wall 36 of the second rail 32, and even when the cabinet 24 is placed incorrectly from top to bottom toward the second rail 32, it can also pass through the bottom wall 36 of the second rail 32. The third guide section 53 at the front end of the second rail 32 is aligned so that the cabinet 24 can be installed on the pair of slide rail assemblies 22 conveniently and quickly.

According to the above description, it can be seen that the improved functions and advantages of the present invention are: the chassis can be quickly installed on the rack, and through the imported design, the chassis can be reliably and stably supported.
