Description of the Invention: [Technical Leadership of the Invention] [0001] The present invention relates to a rail-track mechanism. [Prior Art] [0002] The slide rail mechanism is widely used between two items of relative motion, such as a drawer and a cabinet or table, and between a server and a cabinet. [0003] A common servo slide mechanism is generally a three-load slide rail, which usually includes an inner rail, a middle rail and an outer rail, the outer rail of which is fixed on the support frame of the cabinet, and the inner rail is fixed to the servo. On the side of the device, the middle rail is connected as a load rail between the inner rail and the outer rail to extend the movable range of the server, and the inner rail and the middle rail can be opposite to the twist direction of the outer rail. The outer rail slides back and forth. Therefore, the middle rail and the inner rail need to slide synchronously for a certain distance during the sliding process, and then the inner rail continues to slide out, and the servo can be freely pulled out or pushed back to the cabinet by sliding. However, when the middle rail is not locked in place, that is, when the inner rail is not completely pulled out, the inner rail slides out from the middle rail, so that the inner rail cannot be pushed back to the original position, which affects the normal use of the slide rail. SUMMARY OF THE INVENTION [0004] There is a need to provide a type of slide rail mechanism that is stretched into place.

In the groove 647 of the second positioning body 64. The second positioning end 635 and the fourth positioning end 64 5 of the first positioning body 63 and the second positioning body 64 respectively pass through the first limiting slot 66 and the second limiting slot 67' through the card slot. 639 and the card slot 649 are engaged; the first extending portion 652 and the first extending portion 657 of the first elastic body 65 and the second elastic body 650 respectively abut the second positioning end 635 and the fourth positioning end 645 to prevent the first A positioning body 63 and a second positioning body 64 are separated from one end of the first limiting body groove 66 and the second limiting groove 67. The inner slide rail 10 is mounted on the middle slide rail 3, and the guide rail 14 is slidably mounted in the guide portion 34. The first positioning body 63 is located on the outer slide rail 50 and the inner slide rail 10 The second positioning end 635 is locked on the first limiting end 661 of the first limiting slot 66, and the first extending portion 652 and the second extending portion 653 of the first elastic body 65 are in an open state; The third positioning end 643 of the second positioning body 64 abuts the engaging apex 623 of the engaging body 62 , and the second extending portion 658 of the second elastic body 650 is closed with respect to the first extending portion 657 . Finally, the slide rail 30 of the inner slide rail 10 is mounted on the outer slide rail 5, and the second guide edge 52 receives and guides the guide portion 34 of the middle slide rail 30. The engaging apex 623 of the inner slide rail 〇 62 and the second apex 693 of the second retaining body 69 are on the same horizontal plane; the first apex 613 of the first retaining body 61 and the chute The 695 is on the same level. The middle slide rail 30 is slidably mounted on the outer slide rail 5, that is, the assembly of the slide rail mechanism is completed, and the inner slide rail 1〇 and the middle slide rail 3〇 are closed compared to the outer slide rail 5〇. 099115749 Form No. 1010101 Page 9/Total 25 Page 0992027946-0 201143575 [0018] Please refer to FIG. 5 together, when using the slide rail mechanism, pull the inner slide rail 10 in the direction of the illustrated arrow, that is, the first direction, the second The third positioning end 643 of the positioning body 64 slides along the curved edge 621 from the engaging apex 623 to the lowest point of the curved edge 621. The first positioning end 633 of the first positioning body 63 and the first holding body 61 The third sliding end 643 of the second positioning body 64 slides to the third limit of the second limiting slot 67 during the process. End 671. The second extension 658 of the second elastomer 650 is elastically flared relative to the first extension 657. [0019] Please refer to FIG. 6 to continue pulling the inner slide rail 10, because the first positioning end 633 of the first positioning body 63 is engaged with the first retaining body 61 of the inner slide 10, and the inner slide rail is When the fourth positioning end 645 of the second positioning body 64 slides along the second curved edge 691 of the second holding body 69 to the second apex 693, the sliding portion 30 of the second positioning body 64 slides to the second apex 693. The second positioning body 64 is located at the fourth limiting end 672 of the second limiting slot 67. The second elastic body 650 is elastically closed, and the first positioning body 63 is located at the lowest point of the second curved edge 691. [0020] Please refer to FIG. 7 to continue pulling the inner slide rail 10. When the first positioning body 63 slides to the second curved edge 691, the first positioning end 633 slides over the first vertex, and the first The retaining body 61 is unlocked, and the inner slide rail 10 is unlocked relative to the middle slide rail 30; the second positioning body 64 slides from the second apex 693 into the sliding slot 695, and the first elastic body 65 and the second elastic body 650 are both elastically stretched. In the open state, the latching protrusion 68 is engaged with the retaining wall 697, and the middle rail 30 is locked with the outer rail 50. Continue to pull the inner slide rail 10, the first retaining body 61 passes over the sliding slot 695 and the second positioning body 64, and the inner slide rail 10 slides out relative to the middle slide rail 30, thereby increasing the stretched length of the inner slide rail 10, thereby Take the server host completely out of the cabinet. 099115749 Form No. A0101 Page 10/Total 25 Page 0992027946-0 201143575 [0021] Please refer to FIG. 8 together, when the server is pushed back into the cabinet, the inner slide rail 10 is advanced in the direction of the arrow, that is, in the second direction. The slide rail 10 pushes the middle slide rail 30—the friction force pushes the middle slide rail 30 to slide, but the middle slide and the outer slide rail are still locked by the second positioning body 64 and the sliding slot 695, and the first A first retaining body 63 slides over the first positioning body 64, and the first curved edge 611 slides against the first positioning body 63 to slide in the first limiting slot 66. When the first positioning body 63 slides over the first card After the holding body 61, the second positioning body 64 slides along the curved edge 621 of the engaging body 62 to the engaging apex 623, the friction of the inner sliding rail 10 to the middle sliding rail 30 causes the fourth positioning end 645 to slide. The second apex 693, the middle slide rail 30 and the outer slide rail 50 are unlocked, and the inner slide rail 10 is continuously pushed. The inner slide rail 10 and the middle slide rail 30 resist the gear, and the middle slide rail 30 is driven along The two directions are synchronously moved, and the outer slide rail 50 is slid back to the initial state.
