Description

Buffering and rebound slide rail

Technical Field

The utility model relates to the technical field of drawer sliding rails, in particular to a sliding rail capable of realizing buffer self-closing and rebound opening of a drawer.

Background

The existing drawer slide rail can not only realize buffering self-closing, but also realize rebound opening. The buffering self-closing means that the automatic closing is carried out under the action of the pulling force of a spring and the buffering action of a damper; the rebound opening means that the drawer is opened by the rebound force of the spring by pressing the unlocking rebound force. It is therefore necessary to develop a slide rail that can achieve both self-closing and rebound opening of the drawer.

As can be seen from the drawing, the guide rail seat 3 adopts a conventional T-shaped structure, i.e. a sliding island extends from the center, the first sliding rail 3.1 and the second sliding rail 3.2 are opened on the sliding island in the form of sliding grooves, and the first sliding seat 4 and the second sliding seat 5 are slidably connected with the sliding island. The first pendulum mass 9 and the second pendulum mass 10 are also conventional parts, on which a pin shaft for the articulated connection and a pendulum pin for the sliding, swinging and clutch connection are fixed. The installation position of the pushing block 13 is coincident with the straight rail section of the first sliding rail 3.1, and inclined wedges are arranged at two ends of the pushing block and are used for pushing the swinging pin of the first swinging block 9 to swing into the first bent crutch 3.1.1 and the second bent crutch 3.1.2 so as to avoid the movement of the pushing block 13. The clutch block 14 is provided with a bent crutch 14.1 which can accommodate the swinging pin of the second swinging block 10 to swing in, so that the second swinging block 10 swinging in the bent crutch 14.1 is connected with the clutch block 14 in the straight rail section of the second sliding rail 3.2, and the swinging pin is driven to swing out of the bent crutch 14.1 in the bent rail section of the second sliding rail 3.2, and the combination of the clutch block 14 and the second swinging block 10 is released. The first spring 6 and the second spring 8 are both tension springs, wherein the first spring 6 and the damper 7 are respectively arranged at two sides, and the second spring 8 and the first sliding rail 3.1 are respectively arranged at two sides of the sliding island. The third spring 11 adopts a pressure spring and is arranged between the second spring 8 and the first sliding rail 3.1, and the second sliding seat 5 is provided with a propping part 5.2 propping the third spring 11 at the bottom of the inclined wedge 5.1. The fourth spring 12 adopts a torsion spring and is arranged at the outer side of the second bent crutch 3.1.2, and the torsion spring end presses the swinging pin of the first swinging block 9 to keep the first swinging block 9 to swing out of the second bent crutch 3.1.2 and is positioned at the straight rail section of the first sliding rail 3.1.

The buffer and rebound slide rail shown in fig. 1 is in a state that the drawer is fully opened, and the first spring 6 and the second spring 8 in a natural state keep the first slide seat 4 and the second slide seat 5 to slide to the left side. When the drawer needs to be closed, the drawer is pushed to move rightwards by external force, when the push block 13 touches the swing pin of the first swing block 9, the first swing block 9 is pushed to move rightwards by pushing against the swing pin, when the swing pin moves to the first bent corner 3.1.1, the wedge of the push block 13 slides into the first bent corner 3.1.1 by pushing against the swing pin until the push block 13 is avoided, the first spring 6 and the second spring 8 are stretched and deformed, the push block 13 is locked at the first bent corner 3.1.1 under the action of the tensile force of the spring, and at the moment, the first sliding seat completes the closing and sliding energy storage at the initial stage, so that a power source is provided for finally completing the buffering self-closing of the drawer. Immediately after the clutch block 14 moves to the second swing block 10, the swing pin of the second swing block 10 starts to enter the bent lever 14.1 of the clutch block 14, the bent lever 14.1 drives the second swing block 10 to swing along with the movement of the clutch block 14, the swing pin enters the straight rail section along with the third bent lever 3.2.1 swinging out of the second sliding rail 3.2, at the moment, the clutch block 14 is connected with the second swing block 10, meanwhile, the second sliding seat 5 is unbuckled, under the action of the elastic force of the first spring 6 of deformation and accumulation, the second sliding seat 5 is pulled to move rightwards, the second sliding seat 5 carries the inner rail 2, the inner rail 2 carries the drawer, and meanwhile, the drawer is buffered to self-close under the action of the damper 7. When the abutting part 5.2 of the second sliding seat 5 moves to abut against the third spring 11, the third spring 11 prevents the second sliding seat 5 from moving forwards continuously, so that a certain distance is kept between the second sliding seat and the first sliding seat 4, the locking of the first swinging block 9 is released after the inclined wedge 5.1 bumps against the swinging pin of the first swinging block 9, meanwhile, a pressing space for rebounding to open the drawer is provided, and the buffer self-closing of the drawer is finished. When the drawer needs to be opened, the external force presses the drawer to the right, the wedge 5.1 of the second sliding seat 5 bumps and unlocks the first swinging block 9, the second spring 8 which deforms and stores potential after the external force is removed drives the first sliding seat 4, the second sliding seat 5, the inner rail 2 and the drawer to pop out to the left, when the second swinging block 10 moves to the third bent corner 3.2.1 to swing, the combination of the clutch block 14 and the second swinging block 10 is released, and the clutch block 14, the inner rail 2 and the drawer separated from the second swinging block 10 continuously pop out to the left under inertia to open, so that the pressing rebound opening of the drawer is completed.
