Between slide rail inner side " be that, towards the side of interior slide rail, " outside of middle slide rail " is towards the side of external slide rail.
See Fig. 1, it is a kind of can sequential movements three-sectional sliding-rail, it includes external slide rail 10 and interior slide rail 30, and external slide rail 10 is consolidated
Loaded on cabinet, interior slide rail 30 is installed in mobile side, is slided between external slide rail 10 and interior slide rail 30 by middle slide rail 20
Connection；It is in level that the rear end of middle slide rail 20, which is provided with after a T-shaped hollow slots 21 and the rotated ninety degrees clockwise of hollow slots 21,
Shape is opened up, and the medial surface of middle slide rail 20 is rotationally equipped with a lock piece positioned at the front end of hollow slots 21 by pin 40
50, the latch hook 51 of the front end of lock piece 50 provided with downward bending, rear end bending laterally formed a step-like convex portion 52 and
Step-like convex portion 52 externally protrudes out in the lateral surface of middle slide rail 20 through hollow slots 21, the rear end of lock piece 50 and middle slide rail
By elastic component elastic connection between 20, elastic component is elastic draw bar 60；Interior slide rail 30, external slide rail 10 are towards middle slide rail 20
A convex closure 31,11 and convex closure 31,11 rear ends protruded to the middle one side of slide rail 20 is respectively equipped with one side to be respectively equipped with
The grab 311 of convex closure 31 on grab 311,111, interior slide rail is set upward, and the grab of the convex closure 11 on external slide rail is set down,
The grab 311 of convex closure 31 on interior slide rail can hook to close with the formation of front end latch hook 51 of lock piece 50 and lock and can promote lock piece 50
Rotate, the convex closure 11 on external slide rail 10 can form snap lock with the convex portion of the rear end of lock piece 20 and can promote lock piece 50
Rotate.
The rear end of the latch hook 51 of lock piece 50 is provided with an inclined-plane 53, the back end surface of the grab 311 of the convex closure 31 of interior slide rail
312 can coordinate to promote lock piece to rotate with inclined-plane 53；The rear end of the step-like convex portion 52 of lock piece rear end is curved
And can be caught in the grab 111 of the convex portion of external slide rail；The rear end of convex closure 11 on external slide rail is in the inclined-plane having a down dip from back to front
112。
One side of the middle slide rail 10 towards interior slide rail 30 and the rear end positioned at hollow slots 21 angled are set provided with two
Convex hook 22,23, and two convex hooks 22,23 is in opposite direction, and lock piece 50 is provided with positioning hole 54, the one of elastic draw bar 60
End hooks conjunction, the other end through bending after positioning hole 54 and lock piece 50 and is sequentially clamped in two convex hooks 22,23, so as to give
The pretightning force of elastic draw bar 60 1.
Action process of the present utility model is detailed below：
When slide rail is completely in closure state, the lock piece 50 being installed on middle slide rail 20 is in low early and high after tilting
The latch hook 51 of the state front end of lock piece 50 simultaneously is horizontal and grab 311 with the convex closure 31 on interior slide rail is in hooking conjunction state；
When needing to open slide rail, interior slide rail 30 is pulled along, because the latch hook and interior slide rail of the front end of lock piece 50 are convex
The grab 311 of bag 31, which is hooked, to be closed, therefore middle slide rail 20 is extracted out with synchronous move forward of interior slide rail 30 out of external slide rail 10, until outer
The convex closure 11 of slide rail 10 is contacted with the convex portion 52 in the outside of lock piece 50, and the inclined-plane 112 of the rear end grab 111 of convex closure 11 promotes convex portion
52 cause lock piece 50 rotated clockwise around pin 40 so that the front end latch hook 51 of lock piece 50 be upturned and with
The rear end grab 311 of the convex closure 31 of interior slide rail 30 breaks off relations, and when the lock piece 50 on middle slide rail 20 is moved across external slide rail 10
Convex closure 31 rear end grab 311 after, by elastic draw bar 60 restoring force drive the resilience of lock piece 50 make it that lock piece is step-like
The circular arc rear end of convex portion 52 is caught in the grab 111 of the convex closure 11 of external slide rail 10, so that slide rail 30 is slided with centre on the one hand
Unlocked between rail 20, continue to be pulled along interior slide rail 30 until interior slide rail 30 is opened completely, on the other hand in the middle of slide rail 20 with it is outer
The locking on closing direction is realized between slide rail 10；
When needing to fold slide rail, interior slide rail 30 is promoted backward, now due to the step-like convex portion 52 of the rear end of lock piece 50
Circular arc rear end it is spacing by the stop of the grab 111 of the convex closure 11 of external slide rail, therefore only interior slide rail 30 is folded along middle slide rail 20；
Contact, continue backward with the inclined-plane 53 of lock piece 50 when interior slide rail 30 is moved to the rear end grab 311 of the convex closure 31 of interior slide rail 30
In promoting slide rail 30 inclined-plane 53 of back end surface 312 and the lock piece 50 of grab 311 is coordinated so as to promote lock piece 50 around
Pin 40 is rotated clockwise so that the circular arc rear end of the step-like convex portion 52 of the rear end of lock piece 50 bypasses the convex of external slide rail
The grab 111 of bag 11, so that the locking of middle slide rail 20 and external slide rail 10 in closing direction is released, in the reply of elastic draw bar 60
Power drive lower lock piece 50 rotate counterclockwise and the front end of lock piece 50 the convex closure 31 again with interior slide rail 30 of latch hook 51
Rear end grab 311 engage, continue backward promote in slide rail 30 then in the middle of slide rail 20 with interior slide rail 30 into external slide rail 10
Fold, until closure completely.
