Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cabinet technology, specifically a rebound device, guide rail device and rebound drawer system. Background Technology
[0002] Rebound drawer systems, a common handle-free opening method in modern furniture design, primarily rely on the energy storage and release mechanism of an internal spring or similar elastic element. When the user gently presses the drawer panel, a trigger mechanism senses this action and releases pre-stored elastic energy, causing the drawer to automatically spring out a short distance, allowing the user to fully open it. This design not only enhances the aesthetics of the furniture but also improves ease of use, making it particularly suitable for modern home environments that favor a minimalist style.
[0003] However, traditional rebound drawer systems face a series of adjustment challenges in practical applications. On one hand, errors during installation, such as misalignment of the cabinet and drawer slides, or misalignment of the panel and trigger mechanism, can lead to inconsistent trigger distances. On the other hand, design differences between drawers and cabinets, such as material thickness and the type and specifications of drawer slides, also increase the complexity of adjustment. These factors combined make the adjustment function of traditional rebound drawer systems unstable and difficult to control precisely. When the panel trigger distance is too small, it means that the user needs to press very precisely on a specific position on the drawer panel to activate the rebound mechanism. This not only increases the difficulty of use but may also cause the drawer to fail to pop out smoothly due to improper pressing force or position. Furthermore, a small trigger distance may cause the trigger mechanism to malfunction due to wear or dust accumulation during long-term use, further affecting the stability and reliability of the rebound effect.
[0004] In view of the above problems, the existing rebound drawer system needs to be further improved to solve the problems of unstable adjustment, difficulty in adjustment, and poor rebound effect due to small trigger distance. Utility Model Content
[0005] The first purpose of this invention is to overcome the problems of unstable adjustment, difficulty in adjustment, and poor rebound effect caused by small trigger distance in existing rebound drawer systems, and to provide a rebound device with adjustable trigger distance.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] The rebound mechanism includes a mounting base, a rebound device, and an adjustment mechanism. The mounting base has a first mounting area and a second mounting area at its front and rear, respectively. The rebound device is movably mounted in the first mounting area, having preset first and second positions. It is equipped with a movable rail connecting part and first and second locking positions distributed front and rear. It is connected to the drawer's movable rail via the movable rail connecting part. When the drawer is closed, the rebound device is in the first position. When force is applied, the rebound device automatically moves to the second position, causing the drawer to pop out synchronously. The adjustment mechanism includes a limiting rod. One end of the limiting rod is movably mounted in the second mounting area, and the other end connects to the first locking position when the rebound device is in the first position and to the second locking position when the rebound device is in the second position, thus cooperating with the rebound device to maintain it in the first or second position and adjusting the preset positions of the first and second positions.
[0008] This invention adjusts the preset position of the rebound device via an adjustment mechanism, directly adjusting the gap between the drawer door panel and adjacent components to achieve precise control. Simultaneously, the rebound device is connected to the movable rail via a connecting part, and its adjustment allows for fine adjustments to the drawer panel, ensuring smooth and aligned opening and closing of the drawer panel, coordinated with the adjustment mechanism. Compared to existing technologies, this invention achieves precise adjustment of the rebound trigger distance through the cooperation of the rebound device and the adjustment mechanism, offering simple and quick operation. Furthermore, the adjustment process is more stable, effectively avoiding inconsistencies in trigger distance caused by installation errors or design differences.

When the rebound device is in the first position, the limiting end is engaged with the first locking position; when the rebound device is in the second position, the limiting end is engaged with the second locking position. This solution achieves precise adjustment of the rebound device's position through the mechanical transmission of the adjustment screw, gear, and rack. The position of the rebound device can be adjusted simply by rotating the adjustment screw, making operation simple and quick.

The first locking position, the second locking position, and the movable rail connection part are provided on the linkage mechanism. One end of the elastic connector is fixed, and the other end is connected to the linkage mechanism. When the drawer is closed, the linkage mechanism is in the first position. When subjected to external force, the linkage mechanism moves backward and disengages from the adjustment mechanism through the first locking position. The elastic connector drives the linkage mechanism to move forward to the second position and connects to the adjustment mechanism through the second locking position.
[0011] Furthermore, the adjusting screw has a helical drive portion on its rod end, and the adjusting gear has teeth on its outer wall. The second mounting area includes a screw mounting groove, a gear mounting groove, and a rack mounting groove. The screw mounting groove has a screw connection hole penetrating its side wall. The gear mounting groove is connected to the screw mounting groove and the rack mounting groove, respectively.

[0014] Furthermore, a guide structure is provided between the first mounting area and the transmission component, and the first mounting area guides the movement of the transmission component through the guide structure.
[0015] The trigger is provided with a guide rail, and the first locking position and the second locking position are located on the guide rail.
[0016] Furthermore, it also includes a mounting cover, which covers the rear of the first mounting area and the second mounting area.
[0017] Furthermore, the guide rail is ring-shaped and includes a first rail and a second rail on the upper side. The first locking position is located at the front end connection of the first rail and the second rail, and the second locking position is located at the rear end connection of the first rail and the second rail.
[0018] Furthermore, the rear of the transmission component is provided with a first mounting step, the mounting shaft is located on the first mounting step, the front of the trigger component is correspondingly provided with a second mounting step, and the second mounting step is provided with a mounting hole corresponding to the mounting shaft, and the first mounting step abuts against the second mounting step.
[0019] Furthermore, the second installation area is provided with a limiting seat, and the limiting seat is provided with a clearance groove that runs through its front and rear ends. The limiting rod passes through the clearance groove and is connected to the trigger.
