Description

Technical Field

[0001] The utility model relates to a drawer guide rail, in particular to a drawer rebound guide rail which can be pressed and reset at any position. Background Art

[0002] Drawer guides, a common furniture hardware accessory, are widely used in various cabinet and drawer systems. Traditional drawer guide structures typically consist of static and dynamic rails to ensure smooth slide and opening and closing of drawers. Components such as ball bearings provide a smooth sliding experience during the sliding process. However, as users' demands for furniture functionality continue to increase, guides must not only provide smooth sliding but also automatic opening and closing capabilities. Push-to-rebound guides are a typical example of this improved design.

[0003] A push-and-rebound guide rail is a device that automatically pops open or rebounds the drawer closed by pressing the front end. In existing technical solutions, the guide rail system is typically equipped with a reset buffer mechanism and a push-and-rebound mechanism. The push-and-rebound mechanism's rebound hook interacts with the rebound groove on the guide rail to achieve the push-and-rebound function. However, existing push-and-rebound guide rail structures have the following significant drawbacks, which seriously affect the user experience.

[0004] 1. In the existing push-and-rebound guide rail, in order to realize the push-and-rebound function, the user needs to open the drawer to a specific length so that the rebound hanging groove on the movable slide rail passes over the rebound hook on the push-and-rebound device. In this process, only when the guide rail reaches a specific open position can the rebound hook be released, pushing the push-and-rebound device to reset and prepare for the next push-and-rebound opening. This means that the rebound device of the guide rail cannot be used in any position. The user must manually pull the drawer to a sufficient length and then close the drawer backwards to achieve reset. This operation method has high requirements on the user's usage habits. Especially when using the guide rail for the first time, the user cannot immediately understand and master the operation method, resulting in the inability to use the push-and-rebound function normally.

[0005] 2. Because the push-to-rebound mechanism in existing technology requires sliding to a specific position to reset, it presents a difficult user experience for first-time users. In particular, if the guide rail cannot be slid to the desired length, the user may find that the push-to-rebound mechanism is ineffective, causing significant inconvenience in daily use. For users unfamiliar with this mechanism, especially if the drawer is opened incorrectly, they may mistakenly believe the product has quality issues or is malfunctioning, which in turn affects user satisfaction and market acceptance.

[0006] 3. The design of existing push-and-rebound guide rails requires that the rebound groove and rebound hook precisely align when the rail slides to a specific length, placing high demands on component manufacturing precision and assembly. Even the slightest deviation in the rail structure or during installation can cause the push-and-rebound function to malfunction, preventing the user from smoothly opening or closing the drawer. Furthermore, the rebound hook and groove in the rail structure are prone to wear over time, reducing the rail's service life and reliability and increasing the difficulty and cost of subsequent maintenance. Therefore, further improvements are necessary. Utility Model Content

[0007] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a rebound guide rail which has a simple structure, is easy to use and can be pressed and reset at any position.

[0008] The purpose of the utility model is achieved in the following way: a drawer rebound guide rail that can be pressed and reset at any position, which includes a movable slide rail and a static slide rail. The movable slide rail slides relative to the static slide rail to realize the opening and closing of the drawer. A reset buffer mechanism and a press rebounder are provided between the movable slide rail and the static slide rail. The reset buffer mechanism automatically resets and closes when the slide rail is closed, and the press rebounder realizes the press rebound opening function when the guide rail is opened. A plurality of rebound seats are installed on the movable slide rail, and a plurality of rebound hanging grooves are provided on the side walls of the rebound seat. The rebound hanging grooves are buckled with the rebound hooks on the press rebounder. When the press rebounder rebounds, the rebound hook is buckled with the rebound hanging groove to push the movable slide rail to rebound outward and open.

[0009] Furthermore, an inclined guide surface is provided on the back of the rebound hanging groove, and when the rebound hook contacts the guide surface, the rebound hook is pushed inward to retract.

[0010] Furthermore: the rebound hanging grooves are evenly distributed on the side wall of the rebound seat.

[0011] Furthermore, the rebound seats are selected in corresponding quantity according to the length of the movable slide rail and are installed in series on the movable slide rail.

[0012] Furthermore: the rebound seat includes a front rebound seat and a rear rebound seat, an elastic buckle is provided at the bottom of the front rebound seat, a positioning hole is provided on the movable slide rail, and the front rebound seat is inserted into the positioning hole for installation through the elastic buckle.

[0013] In one embodiment: the front end surface of the rear rebound seat is provided with a connecting pin, and the rear end surface of the rear rebound seat is provided with a connecting hole. When two adjacent rear rebound seats are docked, the rear rebound seat located at the rear uses its connecting pin to insert into the connecting hole of the rear rebound seat located at the front to achieve docking.

[0014] Furthermore: an air avoidance area is provided at the bottom of the front rebound seat corresponding to the position of the connecting pin.

[0015] Furthermore: a connecting plate is installed on the side wall of the movable slide rail, and the positioning hole is provided on the connecting plate.

[0029] The present invention is further described below in conjunction with the accompanying drawings. A drawer rebound guide rail that can be pressed and reset at any position includes a movable slide rail 1 and a static slide rail 2. The movable slide rail 1 slides relative to the static slide rail 2 to realize the opening and closing of the drawer. A reset buffer mechanism 3 and a press rebounder 4 are provided between the movable slide rail 1 and the static slide rail 2. The reset buffer mechanism 3 automatically resets and closes when the slide rail is closed, and the press rebounder 4 realizes the press rebound opening function when the guide rail is opened. The invention is characterized in that: a plurality of rebound seats 5 are installed on the movable slide rail 1, and the side walls of the rebound seat 5 are provided with a plurality of rebound hanging grooves 51. The rebound hanging grooves 51 are locked with rebound hooks 41 on the press rebounder 4. When the press rebounder 4 rebounds, the rebound hook 41 is locked with the rebound hanging groove 51, pushing the movable slide rail 1 to rebound outward and open.

[0030] In one embodiment, an inclined guide surface 52 is provided on the back side of the rebound hanging groove 51. When the rebound hook 41 contacts the guide surface 52, the rebound hook 41 is pushed inward to retract.

[0031] In one embodiment, the rebound hanging grooves 51 are evenly distributed on the side wall of the rebound seat 5 .

[0032] In one embodiment, the rebound seats 5 are selected in corresponding number according to the length of the movable slide rail 1 and are installed in series on the movable slide rail 1 in front and back directions.

[0033] In one embodiment, the rebound seat 5 includes a front rebound seat 53 and a rear rebound seat 54. An elastic buckle 55 is provided at the bottom of the front rebound seat 53. A positioning hole is provided on the movable slide rail 1. The front rebound seat 53 is inserted into the positioning hole for installation through the elastic buckle 55.

[0034] In one embodiment, the front end face of the rear rebound seat 54 is provided with a connecting pin 56, and the rear end face of the rear rebound seat 54 is provided with a connecting hole 57. When two adjacent rear rebound seats 54 are docked, the rear rebound seat 54 located at the rear uses its connecting pin 56 to insert into the connecting hole 57 of the rear rebound seat 54 located at the front to achieve docking.

[0035] In one embodiment, a clearance area 58 is provided at the bottom of the front rebound seat 53 corresponding to the position of the connecting pin 56 .

[0036] In one embodiment, a connecting plate 11 is installed on the side wall of the movable slide rail 1 , and the positioning holes are provided on the connecting plate 11 .

[0037] In one embodiment, the side wall of the connecting pin 56 is further provided with a docking platform 59, and the end surface of the docking platform 59 is concavely provided with a card slot 510. The card slot 510 located on the frontmost rear rebound seat 54 is clamped on the connecting plate 11 and fixed thereto.

[0038] In one embodiment, the rear rebound seat 54 has a rearmost portion that is docked with the synchronizer 6 fixed to the rear end of the movable slide rail 1 .

[0039] Working Principle: Within the entire guide rail system, a movable rail 1 and a stationary rail 2 work together to slide relative to each other, enabling the drawer to open and close. When the user manually pulls or pushes the drawer, the movable rail moves within the rail groove along the stationary rail, completing the drawer's opening and closing motion. During this process, components within the guide rails, such as ball bearings and sliders, ensure smooth sliding.

[0040] The return and buffer mechanism 3 is located between the movable and stationary rails. When the user pushes the drawer back, it provides a cushioning effect, preventing a violent impact when the drawer closes. This not only improves sliding smoothness but also protects the rail and drawer structure, extending the rail's service life.

[0041] The push-rebound mechanism 4 is a key component of the present invention, responsible for realizing the push-rebound opening function. When the drawer is closed, the rebound hook 41 of the push-rebound mechanism engages with the rebound hanging groove 51 on the movable slide. By pressing the front end of the drawer, the rebound hook separates from the hanging groove, and the movable slide is pushed outward by the rebound force of the push-rebound mechanism, thereby causing the drawer to automatically pop out. For the specific working principle of the push-rebound mechanism, please refer to the applicant's prior patent applications: 201810277354.9 and 202321195094.3, which will not be elaborated here.

[0042] Unlike traditional guide rails, the present invention allows users to close the guide rails at any position. Multiple rebound seats can be used to push the push-rebound mechanism to reset the guide rails. Simply pressing the drawer resets the push-rebound mechanism 4, eliminating the need to pull the drawer to a specific length. This design significantly simplifies operation and improves the user experience, making it especially user-friendly for first-time users and avoiding the issues encountered in existing technologies where users struggle to operate smoothly.

[0043] Specifically, the present invention features multiple rebound seats 5 on the movable rail, each with a plurality of rebound slots 51 on its sidewall. These slots engage with rebound hooks 41 on the push-pull mechanism. When the movable rail is pressed by the user, the hook engages with the nearest slot, pushing the push-pull mechanism back into position.

[0044] The multi-point trigger design of this utility model can engage and rebound in multiple positions, without being limited to a fixed point. This not only makes operation more flexible, but also ensures that the guide rail can be smoothly reset in different sliding positions, greatly improving the convenience of the guide rail system.

[0045] Furthermore, the rebound seat 5 of the present invention adopts a modular design, comprising a front rebound seat 53 and a rear rebound seat 54. The front rebound seat is secured to the positioning hole 11 on the movable rail via an elastic buckle 55, while the rear rebound seat is connected to the connecting hole 57 via a connecting pin 56, enabling multi-stage serial installation. The rebound seat can be flexibly configured according to the length of the movable rail, ensuring that rail systems of varying lengths can smoothly achieve rebound and reset functions.

[0046] The modular and serial design makes the guide rail assembly more flexible, and the number of rebound seats can be adjusted according to specific needs to accommodate the installation requirements of drawers of different sizes. At the same time, this design facilitates the installation and maintenance of the guide rail, reducing production complexity and maintenance costs.

[0047] The front end of the rear rebound seat 54 is provided with a connecting pin 56 and the rear end is provided with a connecting hole 57. Adjacent rear rebound seats are connected by plugging and docking the connecting pins and the connecting holes, ensuring a secure connection between each rebound seat. Furthermore, the frontmost rear rebound seat is fixed to the connecting plate 12 on the side wall of the movable slide rail via a slot 510, ensuring a stable installation of the entire slide rail system. The rearmost rear rebound seat also docks with the synchronizer 6 to ensure the synchronized movement of the entire slide rail system when the drawer is opened and closed.

[0048] This stable docking design effectively prevents the rebound seat from loosening and shifting, ensuring system reliability. At the same time, the introduction of the synchronizer ensures accurate rebound action of the guide rail, further improving the operational stability and service life of the slide rail.

[0049] In summary, the present invention represents a significant improvement over traditional push-to-rebound guide rails. This not only simplifies the operating process, allowing users to press at any position to reset the drawer's rebounder, but also eliminates the need for the rail to be punched to a specified opening before resetting the rebounder. The modular rebound seat structure facilitates installation and maintenance, while the stable docking design enhances the reliability and durability of the slide rail system. These technical advantages significantly enhance the user experience, ease of installation, and structural stability of the present invention's drawer rebound guide rail, enabling its widespread application in various furniture systems.
