Description

Technical Field

[0001] The invention 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 rails are a common furniture hardware accessory and are widely used in various cabinets and drawer systems. In the traditional drawer rail structure, in order to achieve smooth sliding and smooth opening and closing of the drawer, the rails are usually composed of static rails and dynamic rails, and components such as ball bearings provide a smooth sliding experience during the sliding process. However, as users' requirements for furniture functionality continue to increase, the rails not only need to have a smooth sliding function, but also need to realize the function of automatic opening and closing. Among them, the push-rebound rail is a typical improved structure.

[0003] The push-rebound guide rail is a device that automatically pops out or rebounds the drawer to close by pressing the front end of the drawer. In the existing technical solutions, a reset buffer mechanism and a push-rebound device are usually provided in the guide rail system. The push-rebound function is achieved by the mutual cooperation between the rebound hook of the push-rebound device and the rebound hanging groove provided on the guide rail. However, the push-rebound guide rail structure of the prior art has the following obvious defects, which seriously affect the user experience.

[0004] 1. In the existing push-rebound guide rail, in order to realize the push-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-rebound device. In this process, only when the guide rail reaches a specific open position can the rebound hook be released, pushing the push-rebound device to reset and prepare for the next push-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 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 failure to use the push-rebound function normally.

[0005] 2. Since the push-to-rebound device in the prior art must achieve the reset function by sliding at a specific position, the operation experience is not friendly for users who use the guide rail for the first time. In particular, when the guide rail cannot be smoothly found to slide to a specific length, the user may find that the push-to-rebound opening function cannot be achieved, which brings many inconveniences to daily use. For those users who are not familiar with such operating mechanisms, especially when the drawer is not opened correctly, they may mistakenly believe that the product has quality problems or failures, which in turn affects user satisfaction and market acceptance of the product.

[0006] 3. The design of the existing push-rebound guide rail needs to ensure that when the guide rail slides to a certain length, the engagement position of the rebound hanging groove and the rebound hook can be accurately matched, which places high requirements on the manufacturing accuracy and assembly of parts. Once there is a slight deviation in the slide rail structure or during the installation process, the push-rebound function may fail, and the user will not be able to open or close the drawer smoothly. In addition, the rebound hook and hanging groove in the guide rail structure are prone to wear during long-term use, which reduces the service life and reliability of the guide rail and increases the difficulty and cost of subsequent maintenance. Therefore, it is necessary to make further improvements to it. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a rebound guide rail which is simple in structure, easy to use and can be pressed and reset at any position.

[0009] Furthermore, an inclined guide surface is arranged 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 arranged at the bottom of the front rebound seat, a positioning hole is arranged on the movable slide rail, and the front rebound seat is installed by inserting the elastic buckle into the positioning hole.

[0013] In one of the embodiments: 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: a clearance 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 arranged on the connecting plate.

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings. A drawer rebound guide rail that can be reset by pressing at any position, comprising a movable slide rail 1 and a static slide rail 2, wherein the movable slide rail 1 slides relative to the static slide rail 2 to realize the opening and closing of the drawer, and a reset buffer mechanism 3 and a press rebounder 4 are arranged between the movable slide rail 1 and the static slide rail 2, wherein the reset buffer mechanism 3 plays an automatic reset and closing role when the slide rail is closed, and the press rebounder 4 realizes a press rebound and opening function when the guide rail is opened, and is characterized in that: a plurality of rebound seats 5 are installed on the movable slide rail 1, and a plurality of rebound hanging grooves 51 are arranged on the side wall of the rebound seat 5, and the rebound hanging grooves 51 are locked with the rebound hooks 41 on the press rebounder 4, and when the press rebounder 4 rebounds, the rebound hook 41 is locked with the rebound hanging groove 51, and the movable slide rail 1 is pushed to rebound outward to 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 of the embodiments, 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 installed by inserting the elastic buckle 55 into the positioning hole.

[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 of the embodiments, a connecting plate 11 is installed on the side wall of the movable slide rail 1 , and the positioning holes are arranged 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 slot 510, and the slot 510 located on the frontmost rear rebound seat 54 is clamped on the connecting plate 11 and fixed thereto.

[0038] In one of the embodiments, the rear rebound seat 54 , a piece located at the rear end is docked with the synchronizer 6 fixed at the rear end of the movable slide rail 1 .

[0039] Working principle: In the entire guide rail system, the movable rail 1 and the static rail 2 cooperate with each other, and the movable rail can slide relative to the static rail to open and close the drawer. When the user manually pulls or pushes the drawer, the movable rail moves along the static rail in the rail groove to complete the opening and closing of the drawer. In this process, components such as the ball bearings or sliders in the guide rails ensure the smoothness of the sliding.

[0040] The reset buffer mechanism 3 is arranged between the movable slide rail and the static slide rail. When the user pushes the drawer back, the reset buffer mechanism can provide a buffering effect to ensure that the drawer does not have a violent impact when closing. The setting of the reset buffer mechanism not only improves the sliding smoothness, but also protects the structure of the guide rail and the drawer, and prolongs the service life of the guide rail.

[0041] The push-rebound device 4 is a key component in the present invention, which is responsible for realizing the push-rebound opening function. When the drawer is closed, the rebound hook 41 of the push-rebound device engages with the rebound hanging groove 51 on the movable slide rail. The user presses the front end of the drawer, and the rebound hook separates from the hanging groove. The movable slide rail is pushed outward by the rebound force of the push-rebound device, so that the drawer pops out automatically. Among them, please refer to the applicant's prior patent applications: 201810277354.9 and 202321195094.3 for the specific working principle of the push-rebound device, which will not be repeated here.

[0042] Unlike traditional guide rails, the present invention allows users to close the guide rails at any position, and multiple rebound seats can be used to push the push rebounder to reset. Pressing the drawer can push the push rebounder 4 to reset, without pulling the drawer to a specific length. This design significantly simplifies the operation steps and improves the user experience, especially for first-time users, and avoids the problem of users being unable to operate smoothly in the prior art.

[0043] Specifically, the present invention designs a plurality of rebound seats 5 on the movable slide rail, and each rebound seat side wall is provided with a plurality of rebound hanging grooves 51. These rebound hanging grooves engage with the rebound hooks 41 on the pressing rebounder. When the movable slide rail is pressed by the user, the hooks engage with the nearest hanging grooves, thereby pushing the rebounder to reset.

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

[0045] In addition, the rebound seat 5 of the present invention adopts a modular design, including a front rebound seat 53 and a rear rebound seat 54. The front rebound seat is fixed to the positioning hole 11 on the movable slide rail by an elastic buckle 55, and the rear rebound seat is connected to each other by a connecting pin 56 and a connecting hole 57 to achieve multi-stage series installation. The rebound seat can be flexibly configured according to the length of the movable slide rail to ensure that slide rail systems of different lengths can smoothly realize the rebound and reset functions.

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

[0047] Among them, 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. The adjacent rear rebound seats are connected by plugging and docking the connecting pins and the connecting holes, ensuring the stable connection between the rebound seats. In addition, the frontmost rear rebound seat is fixed to the connecting plate 12 of the side wall of the movable slide rail through the card slot 510, realizing the stable installation of the entire slide rail system. The rearmost rear rebound seat is also docked with the synchronizer 6 to ensure the synchronous action of the entire slide rail system when the drawer is opened and closed.

[0048] This stable docking design allows the rebound seat to effectively prevent loosening and displacement, ensuring the reliability of the system. At the same time, the introduction of the synchronizer ensures that the rebound action of the guide rail is accurate and correct, further improving the operational stability and service life of the slide rail.

[0049] In summary, the present invention has made significant improvements on the basis of the traditional push-to-rebound guide rail. It not only simplifies the operation process, allowing the user to press at any position to reset the rebounder of the drawer, but also the guide rail does not need to be punched to a specified opening to reset the rebounder. The modular rebound seat structure is easy to install and maintain, and the stable docking design enhances the reliability and durability of the slide rail system. These technical advantages have significantly improved the user experience, installation convenience and structural stability of the drawer rebound guide rail of the present invention, and can be widely used in various furniture systems.

[0050] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
