Detailed Description

The utility model is further described below with reference to the drawings and examples.

Referring to fig. 1-9, a synchronous rebound structure for a sliding rail comprises a mounting box 10, wherein a sliding block 20 is arranged on the mounting box 10 in a left-right sliding manner, the sliding block 20 and the mounting box 10 are connected with a first elastic piece 200, a swing rod 30 is hinged on the sliding block 20, and a hanging needle 310 is arranged on the swing rod 30;

the installation box 10 is internally provided with a circulation guide groove 100, the circulation guide groove 100 is composed of a force storage section 101, a locking section 102 and a release section 103 which are connected end to end, the hanging needle 310 is movably arranged in the circulation guide groove 100, a moving block 410 is arranged in the installation box 10 on the right side of the circulation guide groove 100 in a sliding manner, a limiting piece 411 which extends into the circulation guide groove 100 and is used for limiting the hanging needle 310 to slide into the release section 103 from the locking section 102 is arranged on the moving block 410, the moving block 410 and the installation box 10 are connected with a second elastic piece 420, a limiting assembly 50 which is used for limiting the moving block 410 to reset leftwards is arranged in the installation box 10, and a driving piece 210 which is used for driving the limiting assembly 50 to unlock and reset the moving block 410 is arranged on the sliding block 20.

When the drawer is closed, the sliding block moves rightwards along with the closing of the drawer sliding rail, the hanging needle moves in the circulating guide groove until the drawer is completely closed, and the hanging needle moves to the locking section and is limited by the limiting piece, so that the sliding block is locked. When the lock is unlocked, the drawer is pressed to drive the hanging needle to push the moving part to move to the right, and after the moving part moves to the right, the limiting component can restrict the moving part to enable the moving part not to reset to the left, so that the moving part drives the limiting part to move to the right to vacate the space for the hanging needle to pass through the locking section. The sliding block is enabled to pop up to the left under the action of the second elastic piece, and in the process of popping up, the driving piece drives the limiting component to release the constraint on the moving piece, so that the moving piece is reset under the action of the second elastic piece. According to the utility model, in the processes of locking and releasing the stored force and ejecting, the hanging needle is only contacted with the moving part, so that one-time contact unlocking release is realized, and the contact of parts is reduced to reduce the generation of noise.

Referring to fig. 8, the limiting assembly 50 includes a rotating shaft 530 rotatably disposed on the mounting box 10, a toggle groove 531 is disposed on the rotating shaft 530, and a toggle block 412 extending into the toggle groove 531 is disposed on the moving block 410. The function of the toggle block 412 is to drive the rotation shaft 530 to rotate forward or backward during the left-right movement of the moving block 410.

Referring to fig. 1, a reset member 510 is slidably disposed in the mounting box 10 at the left side of the rotating shaft 530, and a linkage member 511 hooked with the driving member 210 is disposed on the reset member 510. When the slider 20 moves leftward, the driving member 210 pushes the linkage member 511 to drive the reset member 510 to move leftward.

Referring to fig. 8, a limit boss 512 is disposed at the right end of the reset element 510, and a locking boss 532 is disposed on the rotating shaft 530.

When the hanging pin 310 enters the locking section 102 in the locked state, the limit boss 512 and the locking boss 532 fit together as shown in fig. 2. When the lock is unlocked, the hanging pin 310 drives the moving block 410 to move to the right, and in this process, the rotating shaft 530 rotates clockwise, so that the locking boss 532 presses the limiting boss 512 to bring the upper part of the limiting boss 512 and attach to the limiting boss 512, as shown in fig. 6, in this state, the moving block 410 cannot be completely reset to the left through the second elastic member 420.

When the hanging needle 310 enters the releasing section 103 and the sliding block 20 moves leftwards, the driving member 210 pushes the linkage member 511 to drive the reset member 510 to move leftwards, and in the process, the limit boss 512 leaves from below the locking boss 532, so that the locking boss 532 has a space for moving downwards, and the second elastic member 420 drives the moving block 410 to reset leftwards.

Referring to fig. 1, the reset element 510 is connected to the mounting box 10 by a third elastic element 520. The third elastic member 520 is a tension spring, and when the slider 20 moves rightward, it pulls the tension spring to store the force.
