Description

Technical Field

[0001] The utility model relates to the technical field of drawer slide rail rebounders, in particular to a trigger pop-up structure for a slide rail. Background Art

[0002] Prior art, such as the Chinese invention patent document with publication number CN116458738B, discloses a pop-up mechanism with a short trigger stroke, comprising a rebounder mounted on the inside of a cabinet and a pin mounted on the bottom of a drawer. The rebounder comprises a rebound base, a force-storage slide mounted on the rebound base, a force-storage tension spring, a first locking element, a second locking element, and a hook pin. The rebound base is provided with a circulation guide groove comprising a force-storage section and a return section connected end to end. The hook pin is mounted to the force-storage slide via a rocker arm and slides in the circulation guide groove. When the drawer is pushed in, the force-storage tension spring is stretched to store force.

[0003] In the prior art, when the drawer is closed, the movable rail pushes the entire ejection mechanism to perform a force-storing action with the force-storing slide as the force-bearing point. In this process, since the force-bearing point is the force-storing slide, the swing arm is not subjected to force and will not swing arbitrarily, that is, the hanging pin will not move arbitrarily.

[0004] Based on the above, the technical problem existing in the existing technology is that when the moving rail needs to be driven with the rocker arm as the force point due to design requirements, since the rocker arm is a rotating connection, when it is subjected to force, the rocker arm will cause the hanging needle to directly enter the reset section from the release port between the tail end of the reset section and the force storage section under the action of force, thereby causing the entire pop-up mechanism to fail to operate normally.

[0005] Therefore, there is an urgent need for a trigger pop-up structure that can prevent the hanging needle from entering the release track groove from the storage track groove through the release port to solve the above problem. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See also Figures 1-6 A trigger pop-up structure for a slide rail includes a base 10, on which a force storage track groove 101 and a release track groove 102 are provided. The tail end of the force storage track groove 101 is connected to the release track groove 102 to form a locking space 103, and the tail end of the release track groove 102 is connected to the force storage track groove 101 to form a release port 105. A deformable member 30 is provided at the release port 105.

[0029] The deformable member 30 is configured to prevent the hanging needle 230 from entering the release trajectory groove 102 from the storage trajectory groove 101 through the release port 105; when the hanging needle 230 enters the storage trajectory groove 101 from the release trajectory groove 102 through the release port 105, the deformable member 30 is deformed to allow the hanging needle 230 to enter the storage trajectory groove 101.

[0030] See also Figure 1 and Figure 2In this trigger-pop-up mechanism, when the drawer is closed, the movable rail drives the pusher 100 to move synchronously. During this movement, under the action of the first push block 110, the rocker 210 moves rightward, simultaneously driving the movable member 20 and the hook pin 230 to the right. The deformable member 30 prevents the hook pin from entering the release track groove 102 from the power storage track groove 101 through the release opening 105.

[0031] Furthermore, the deformable member 30 includes a connecting seat 320 fixedly disposed on the base 10 , and a deformable piece 310 is connected to the connecting seat 320 . The deformable piece 310 is located in the release port 105 .

[0032] Specifically, the deformable sheet 310 is extended to the left side and the left end of the deformable sheet 310 abuts against the left side wall of the release port 105, as shown in FIG. Figure 2 shown.

[0033] See also Figure 2 The wall of the force storage track groove 101 is provided with an escape groove 104. When the deformable member 30 is deformed, it can be embedded in the escape groove 104. The function of the escape groove 104 is to allow the deformable member 30 to deform and enter the escape groove 104, so that the deformable member 30 has sufficient deformation space to facilitate the hook needle 230 to enter the force storage track groove 101 from the release port 105.

[0034] See also Figure 1 and Figure 2 A locking member 40 is provided on the base 10 for left and right movement. The locking member 40 is provided with a locking end 400 extending into the locking space 103. The locking member 40 is connected to the base 10 by a first elastic element 410.

[0035] The first elastic element 410 is configured to apply a force to the locking member 40 to keep the locking end 400 in the locking space 103 to constrain the hooking pin 230 from moving toward the tail end of the release track slot 102;

[0036] The base 10 is provided with a limiting assembly 60 for limiting the locking end 400 from moving to the locking space 103 .

[0037] When the locking end 400 is within the locking space 103, it restricts the movement of the hook pin 230, keeping the entire trigger pop-up structure in the charged state. When the drawer is pressed again, the locking member 40 moves rightward and compresses the first elastic element 410, moving the locking end 400 away from the locking space 103. The hook pin 230 can then pass through the locking space 103, and the entire trigger pop-up structure enters the released state.

[0038] See also Figure 2A moving member 20 is provided on the base 10 for movement left and right, a rocker rod 210 is rotatably provided on the moving member 20, the hanging needle 230 is provided on the rocker rod 210, a triggering member 220 is movably provided on the rocker rod 210 for triggering the pushing member 100, and a second elastic element is connected between the triggering member 220 and the rocker rod 210.

[0039] During the drawer closing process, the push member 100 moves, and the first push block 110 abuts against the trigger member 220 to push the swing rod 210 to drive the hanging pin 230 and the moving member 20 to move toward the right.

[0040] The trigger member 220 is movable. When the drawer is closed to the end, the movable member 20 cannot continue to move to the right. The first push block 110 squeezes the trigger member 220, causing it to deform. That is, the trigger member 220 moves downward to make way, so that the first push block 110 passes over the trigger member 220 and comes to the right side of the trigger member 220. Figure 5 shown.

[0041] See also Figures 2 to 4 An unlocking member 50 is provided on the base 10 for movement left and right, and a third elastic element 107 is connected to the base 10. A first rack 106 is provided on the base 10, and a transmission gear 510 is rotatably provided on the unlocking member 50. A second rack 200 is provided on the moving member 20, and the transmission gear 510 is respectively engaged with the first rack 106 and the second rack 200.

[0042] See also Figure 3 and Figure 4 The limiting assembly 60 includes a moving block 610 that moves up and down on the base 10, a limiting block 611 is provided on the moving block 610, a driving member 620 is provided on the base 10 for left and right movement, a driving inclined slot 622 is provided on the driving member 620, and a driven inclined block 612 that is movably inserted into the driving inclined slot 622 is provided on the moving block 610;

[0043] The driving member 620 and the base 10 are connected with a fourth elastic element 630;

[0044] The driving member 620 is configured to: when the driving member 620 moves left and right, it cooperates with the driven inclined block 612 through the driving inclined slot 622 to drive the moving block 610 to move up and down;

[0045] The limiting block 611 abuts against the locking member 40 to constrain the locking member 40 to drive the locking end 400 to move into the locking space 103;

[0046] The driving member 620 is provided with a linkage groove 621 , and the unlocking member 50 is provided with a linkage protrusion 520 that is movable and inserted into the linkage groove 621 .

[0047] When the drawer is pressed to open it, the drawer drives the movable rail to push the pushing member 100 to move. The pushing member 100 pushes the unlocking member 50 to move toward the right through the second pushing block 120. During the movement of the unlocking member 50, the first rack, the transmission gear and the second rack are linked to drive the moving member 20 to move toward the right, that is, the hanging pin 230 moves toward the right and pushes the locking member 40 to move toward the right, so as to drive the locking end 400 away from the locking space 103. At this time, the limit block 611 has upward space. Under the action of the fourth elastic element 630, when the driving member 620 moves toward the right, it cooperates with the driven bevel block 612 through the driving bevel groove 622 to drive the moving block 610 to move upward, so that the limit block 611 moves upward and abuts against the left side of the locking member 40 to prevent the locking end 400 from entering the locking space 103, that is, the hanging pin 230 can pass through the locking space 103 and move toward the tail end of the release track groove 102, thereby entering the pop-up state under the pulling force of the third elastic element 107, and the drawer is opened.

[0048] During the drawer opening process, the unlocking member 50 moves to the left. When it reaches the preset position, the linkage protrusion 520 moves to the left end of the linkage slot 621. That is, the linkage protrusion 520 cooperates with the linkage slot 621, driving the driving member 620 to move to the left. The driving inclined slot 622 cooperates with the driven inclined block 612 to drive the moving block 610 downward. In other words, the limiting block 611 moves downward, thereby allowing the locking member 40 to move to the left. Under the action of the first elastic element 410, it pushes the locking member 40 to move to the left, causing the locking end 400 to enter the locking space 103, thereby once again maintaining the state of restricting the movement of the hanging pin 230.
