DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Embodiment 1:

[0031] Reference Figure 1-Figure 5 , double-function buffer rebounder for slide rails, including:

[0032] Outer rail 1;

[0033] The middle rail 2 is slidably connected to the outer rail 1;

[0034] An inner rail 3 is slidably connected to the middle rail 2;

[0035] A main body 4 is fixedly connected to the outer rail 1;

[0036] A slide plate 5 is slidably connected to the main body 4;

[0037] A slider 6 is fixedly connected to the slide plate 5;

[0038] A tooth hook 9 is fixedly connected to the inner rail 3;

[0039] A hook groove is provided on the tooth hook 9;

[0040] The rotary piece 7 is rotatably connected to the slider 6, and the rotary piece 7 and the hook groove of the tooth hook 9 match each other.

[0041] A sliding hook 10 is rotatably connected to the slide plate 5 , and a push block 11 is slidably connected to the slide plate 5 , and the push block 11 and the inner rail 3 are against each other.

[0042] A limit slide groove 401 is provided on the main body 4, and the slide hook 10 is slidably connected in the limit slide groove 401. The bottom of the push block 11 is fixedly connected to the limit block 1101, and the limit block 1101 and the slide hook 10 are against each other.

[0043] A damping rod 8 is fixedly connected to the main body 4 , and a driving end of the damping rod 8 abuts against the sliding block 6 .

[0044] A first tension spring 15 is fixedly connected to the slider 6 , and one end of the first tension spring 15 away from the slider 6 is fixedly connected to the slide plate 5 .

[0045] The slider 6 is also fixedly connected to a second tension spring 13 , and one end of the second tension spring 13 away from the slider 6 is fixedly connected to the push block 11 .

[0046] A compression spring column 12 is fixedly connected to the slider 6 , and a rebound compression spring 14 is sleeved on the compression spring column 12 . One end of the rebound compression spring 14 is fixedly connected to the slider 6 , and the other end of the rebound compression spring 14 is fixedly connected to the main body 4 .

[0047] Reference Figure 1-Figure 5 When closing the slide rail, by pushing the inner rail 3 to slide, the sliding of the inner rail 3 will push the push block 11 to slide. At this time, the first tension spring 15 and the rebound compression spring 14 will move synchronously with the slide plate 5. During the sliding process of the push block 11, the limit block 1101 at the bottom of the push block 11 will squeeze the slide hook 10. At this time, the slide hook 10 will rotate to contact the slide plate 5 after being squeezed. At this time, the inner rail 3 will continue to slide inward. After sliding for a distance, the tooth hook 9 on the inner rail 3 will slide to the position of the rotary vane 7. At this time, the rotary vane 7 will rotate and slide into the tooth hook 9, pushing the rotary vane 7 out of the positioning angle. The slider 6 is buffered and closed under the action of the damping rod 8, the first tension spring 15 and the second tension spring 13, and at the same time drives the inner rail 3 to buffer and close.

[0048] Reference Figure 1-Figure 5 When opening the slide rail, the staff pushes the inner rail 3 inward again. After pushing 4 mm, the sliding hook 10 disengages from the limiting angle of the limiting slide groove 401. At this time, the rebound compression spring 14 drives the slide plate 5 to rebound and open, and the slider 6 and the rotary vane 7 are opened at the same time. The rotary vane 7 rotates to restore to the positioning angle, and the push block 11 is simultaneously ejected and reset. At this time, the inner rail 3 can be completely rebounded and opened.

[0049] When the utility model closes the drawer, the buffer can make the drawer slide inwards for a certain distance and then slowly close automatically, achieving the effect of silent closing and safety; when the drawer rebounds and opens, the inner rail 3 is pushed inwards again, and the drawer automatically pops out, achieving the effect of automatically opening the drawer and eliminating the need to install a handle.
