Description

Slide mechanism

The invention relates to a slide rail mechanism.

The slide rail mechanism is widely used between two items of relative motion, such as drawers and cabinets or tables, and between servers and cabinets.

The common servo slide mechanism is generally a three-section slide rail, which usually includes an inner rail, a middle rail and an outer rail. The outer rail is fixed on the support frame of the cabinet, and the inner rail is fixed on the side of the server. The upper rail is connected as a carrier 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 moved back and forth relative to the outer rail along the length of the outer rail. Sliding, 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 the sliding rail. However, when the middle rail is not locked in the outer rail, 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.

In view of this, it is necessary to provide a slide rail mechanism that is locked in place.

The holding component includes a first holding body and a second holding body disposed on the inner slide rail, a positioning body slidingly disposed on the middle sliding rail, and a third holding body disposed on the outer sliding rail. When the inner slide rail slides forward, the positioning body is engaged with the second retaining body to realize the inner slide rail is locked on the middle slide rail and continues to slide forward relative to the outer slide rail until the positioning body slides to When the third holding body slides along the second holding body, the inner sliding rail is unlocked relative to the middle sliding rail, and when the inner sliding rail slides backward, the positioning body is engaged with the third holding of the outer sliding rail. The body slides the slide rail backwards relative to the outer slide rail until the first retaining body of the inner slide rail slides over and pushes the positioning body to disengage the positioning body from the third retaining body of the outer slide rail .

Compared with the prior art, the slide rail mechanism is locked by the second latching body of the inner slide rail to lock the inner slide rail relative to the middle slide rail and stably slide synchronously, when the positioning body slides to When the third apex of the outer slide rail slides along the second retaining body, the middle slide rail is locked to the outer slide rail, and the inner slide rail and the middle slide rail are unlocked at this time; effectively preventing the inner slide rail from being separated from the middle slide rail in advance Can't push back.

The first positioning edge 14 is slidably mounted in the guiding portion 34, and the first positioning end of the positioning body 63 is resisted. The first guiding edge 14 is slidably mounted on the guiding portion 34. At the first apex 613 of the first retaining body 61, the second extending portion 643 is elastically closed with respect to the first extending portion 642; the sliding rail 30 of the inner sliding rail 10 is mounted on the outer sliding rail 50, The second guiding edge 52 receives the guiding portion 34 of the middle sliding rail 30 and abuts the folding edge 36. The middle sliding rail 30 is slidably mounted on the outer sliding rail 50. Figure 4 shows the inner rail 10, the middle rail 30 and the outer rail 50 in a closed state.

Referring to FIG. 5 and FIG. 6 together, when the slide rail mechanism is slid, the inner slide rail 10 is pulled in the direction of the arrow shown in the figure. The first positioning end 633 of the positioning body 63 is first along the first retaining body 61. The curved edge 611 slides from the first apex 613 until it slides to the lowest point of the first curved edge 611 and is engaged with one end of the second holding body 62, and the inner slide rail 10 slides away from the middle slide rail 30 by a distance. At this time, the inner slide rail 10 is relatively locked with the middle slide rail 30. In this process, the positioning body 63 slides along the limiting slot 65 to the first limiting end 651, and the second extension portion 643 of the elastic body 64. The first extension 642 is elastically opened.

Referring to FIG. 7 , the inner slide rail 10 is continuously pulled, because the first positioning end 633 of the positioning body 63 is engaged with the second retaining body 62 of the inner slide rail 10 , so that the inner slide rail 10 drives the neutral slide rail 10 . The rail 30 slides relative to the outer slide rail 50. The second positioning end 635 slides to the third retaining body 66 and slides along the third curved edge 661 to the edge of the slot 662. At this time, the positioning body 63 is located. The second extending portion 643 of the elastic body 64 is closed relative to the first extending portion 642; the inner sliding rail 10 continues to pull the middle sliding rail 30 to slide relative to the outer sliding rail 50, and the elastic body 64 releases elasticity. The second positioning end 635 of the positioning body 63 slides into the card slot 662. During this process, the first positioning end 633 and the second holding body 62 of the inner slide rail 10 are held in a locked state.

Referring to FIG. 8 , the inner slide rail 10 is further pulled. The second retaining body 62 slides the second positioning end 635 along the slope between the slot 662 and the third apex 663 to the third apex 663. The first positioning end 633 of the positioning body 63 is located on the second apex 623 of the second curved edge 621. The holding protrusion 655 is engaged with the retaining wall 664 of the third holding body 66. The slide rail 30 is locked with the outer slide rail 50. At this time, the elastic body 64 is in a closed state and stores the elastic potential energy. The positioning body 63 is located at the second limiting end 652 of the limiting slot 65, and then continues to pull the inner sliding rail 10, and the first positioning end 633 is along the second curved shape. The edge 621 slides to the lowest point, and the inner slide rail 10 is unlocked relative to the middle slide rail 30, and continues to pull the inner slide rail 10, which slides out relative to the middle slide rail 30, thus increasing the stretched length of the inner slide rail 10, and the server is The main unit is completely drawn out of the cabinet.

When the servo is pushed back into the cabinet, the inner slide rail 10 is pushed. The second curved edge 621 of the second retaining body 62 slides the first positioning end 633 of the positioning body 63 to the second vertex 623. The friction between the slide rail 10 and the middle slide rail 30 causes the middle slide rail 30 to slide back. When the second apex 623 slides over the third apex 663, the second positioning of the positioning body 63 is due to the sliding of the middle slide rail 30. The end 635 slides into the card slot 662 along the slope, so that the middle rail 30 and the outer The slide rail 50 continues to be locked, and the inner slide rail 10 is further pushed to slide the first positioning end 633 of the positioning body 63 to the first apex 613 of the first retaining body 61. The second positioning end 635 slides out of the card slot 662. The middle slide rail 30 is unlocked relative to the outer slide rail 50. In addition, the inner slide rail 10 and the middle slide rail 30 are resisted to continue to push the inner slide rail 10, and the inner slide rail 10 drives the middle slide rail 30. Synchronous movement, sliding relative to the outer slide 50 back to the initial state.
