Description

Technical Field

[0001] The utility model relates to a hardware guide rail, in particular to a synchronous pressing rebounder for a drawer guide rail. Background Art

[0002] In modern home and office environments, the design and functionality of drawers have become important factors in improving space efficiency and user convenience. As a key component of drawer movement, the performance of drawer guides directly affects the user experience of drawers. In recent years, in order to improve ease of use and safety, the push-rebound guide system has been widely used. This system allows users to automatically open the drawer with a simple press operation, greatly increasing the ease of use and interactivity of the drawer.

[0003] However, the existing push-rebound rail system has certain technical limitations and defects. One of the most significant problems is that the rebound mechanisms on the left and right sides cannot be effectively released synchronously during use. Ideally, when the user slightly presses the front end of the drawer, the rebound mechanisms on the left and right rails of the drawer should be activated at the same time and push the drawer open in a coordinated manner. However, due to factors such as manufacturing tolerances, installation errors or wear caused by long-term use, the rebound rails in the prior art often cannot ensure perfect synchronization of the rebound mechanisms on the left and right sides.

[0004] This lack of synchronization can lead to a variety of usage problems. The most direct consequence is that the drawer is prone to jamming or unevenness when it rebounds when pressed. In more serious cases, if the rebound mechanism on one side releases prematurely, while the other side is slow or fails to release, the drawer may become skewed, increasing the risk of getting stuck or blocked. In addition, this unsynchronized rebound mechanism may also have a negative impact on the overall durability and reliability of the rail system. Over time, frequent unbalanced loads may accelerate the wear of the rail and its components, reducing the service life of the entire system, so it is necessary to make further improvements.

[0032] The utility model is further described in detail below with reference to the accompanying drawings. A drawer guide rail synchronous pressing rebounder, characterized in that it comprises:

[0033] The main body 1 is fixed on the static slide rail 2 of the guide rail, and the main body 1 is provided with a first guide rail 11, a second guide rail 12, a first slideway 23 and a second slideway 24;

[0034] The first slider 3 is clamped on the first guide rail 11 and slides along the first guide rail 11. The first guide rail 11 is also equipped with a second slider 4, which is hinged to the first slider 3. The second slider 4 is provided with a first hook 41 which hooks or separates with a reset hook 51 provided on the movable slide rail 5 of the guide rail, so as to drive the movable slide rail 5 to automatically reset when it is closed;

[0035] A third slider 6 is slidably mounted in the first slideway 23. A first tension spring 61 is provided between the first slider 3 and the first slideway 23. The first tension spring 61 pulls the third slider 6 to always move in the guide rail opening direction. A second tension spring 62 is provided between the third slider 6 and the first slider 3. The second tension spring 62 pulls the first slider 3 to always move in the direction of the third slider 6.

[0036] The fourth slider 7 is hingedly mounted on the third slider 6 and moves along the second guide rail 12. The fourth slider 7 is provided with a second hook 71 which is hooked or separated with the rebound hook pin 52 provided on the movable slide rail 5, so as to push the movable slide rail 5 to rebound and open;

[0037] The fifth slider 8 is installed in the first slideway 23 and is located at the tail of the third slider 6. The side wall of the fifth slider 8 is provided with a tripping inclined surface 81 which contacts with the reverse thrust inclined surface 72 provided on the side wall of the fourth slider 7 to push the fourth slider 7 to swing;

[0038] The linkage mechanism is connected to the fifth slider 8. The linkage mechanisms of the left and right sets of slide rail mechanisms are connected through a synchronization mechanism. When any fifth slider 8 of the left and right sets of slide rail mechanisms moves, the fifth slider 8 on the other side can be driven to move through the linkage mechanism and the synchronization mechanism, so that the fourth sliders 7 of the left and right sets of slide rail mechanisms are released synchronously, and the movable slide rail 5 is synchronously pushed to rebound and open.

[0039] Furthermore, the synchronization mechanism is a synchronization gear 9 rotatably mounted in the first slideway 23 , and the synchronization gear 9 is meshed with a rack 82 arranged on the fifth sliding block 8 .

[0040] Furthermore, the first slideway 23 is provided with a clearance groove 25 in the direction of the slide rail mechanism on the other side, a rolling seat 26 is installed in the clearance groove 25, and the synchronous gear 9 is rotatably installed in the rolling seat 26 through a linkage shaft 91.

[0041] Furthermore, a push spring 83 is provided between the fifth slider 8 and the first slideway 23 , and the push spring 83 pushes the fifth slider 8 to always move toward the direction of the third slider 6 .

[0042] Furthermore, the end surface of the linkage shaft 91 is concavely provided with a coupling hole 92 , and the synchronization mechanism is connected to the coupling hole 92 .

[0043] Furthermore, the synchronization mechanism is a synchronization rod 93 installed between the left and right sets of slide rail mechanisms, and both ends of the synchronization rod 93 are respectively connected to the linkage mechanism.

[0044] Furthermore: both ends of the synchronization rod 93 are provided with synchronization shafts, and the synchronization shafts are connected to the linkage mechanism.

[0045] Furthermore: the first guide rail 11 includes a first main rail portion 111 parallel to the first slideway 23 and a first auxiliary rail portion 112 tangent to the first guide rail 11, the first main rail portion 111 and the first auxiliary rail portion 112 are distributed in an "L" shape, and the second slider 4 is docked with the reset hanging pin 51 when running on the first main rail portion 111, and the second slider 4 is separated from the reset hanging pin 51 when running on the first auxiliary rail portion 112.

[0046] Furthermore: the second guide rail 12 includes a second main rail portion 121 parallel to the first slide 23 and a second auxiliary rail portion 122 tangent to the second guide rail 12, the second main rail portion 121 and the second auxiliary rail portion 122 are distributed in an "L" shape, and the fourth slider 7 is docked with the rebound hanging needle 52 when running on the second main rail portion 121, and the fourth slider 7 is separated from the rebound hanging needle 52 when running on the second auxiliary rail portion 122.

[0047] Furthermore: the fourth slider 7 is provided with a reset push block 74 in the direction toward the main body 1, and the main body 1 is provided with a reset stop block 75. The relative surfaces of the reset push block 74 and the reset stop block 75 are arranged in an inclined state. When the reset push block 74 moves toward the reset stop block 75, the relative surfaces squeeze each other to push the fourth slider 7 to separate from the second main rail portion 121.

[0048] Working principle: The core of this device is a main body fixed to the static slide rail of the drawer. This main body is designed with two parallel rails (first rail and second rail) and two slides (first slide and second slide), which provide the motion path for each subsequent slider assembly. This layout allows each slider to perform precise linear or articulated motion along a predetermined path, ensuring the coordination and precision of the movement of the entire device.

[0049] When the guide rail is opened, the user pulls the movable slide rail outward through the drawer, thereby using the reset pin to pull the first slider and the second slider outward. When the second slider enters the first secondary slider from the first main rail portion 111 to the first secondary rail portion 112, the second slider is deflected, forcing the second slider to disengage from the reset pin, and the guide rail is opened outward.

[0050] When the guide rail is closed, the reset hook hits the second slider, the second slider deflects and hooks with the reset hook again, and the second slider is pulled by the second tension spring and the action of the damping cylinder between the first slider and the third slider to achieve reset buffer closing.

[0051] It should be noted that: when the user closes the guide rail, the user uses the rebounding hook at the tail of the movable slider to push the fourth slider 7 from the second main rail portion 121 to the second secondary rail portion 122. When it moves into the second secondary rail portion 122, the fourth slider deflects and separates from the rebounding hook 52, and the guide rail continues to close. When the fourth slider moves, it simultaneously pulls the first pull ring through the third slider 6 to store energy in preparation for rebound.

[0052] When the user needs to open the drawer, the drawer is slightly pressed, and the movable slide rail pushes the first, second, third, and fourth sliders to move inward through the reset hanging pin, and the fourth slider uses the reset push block 74 thereon and the reset stopper 75 provided on the main body 1 to press against each other, pushing the fourth slider 7 to deflect and separate from the second main rail portion 121. Under the pulling action of the first tension spring, the fourth slider pushes the guide rail in the opposite direction to open.

[0053] Usually, in order to achieve synchronous force on both sides of the drawer, rebound mechanisms are installed in the guide rails on both sides. In order to achieve synchronous release of the rebound mechanisms on both sides, the synchronization mechanism in this case is a synchronization gear 9 rotatably installed in the first slide 23, and the synchronization gear 9 is meshed with a rack 82 set on the fifth slider 8. A clearance groove 25 is opened in the first slide 23 in the direction of the slide mechanism on the other side, and a rolling seat 26 is installed in the clearance groove 25. The synchronization gear 9 is rotatably installed in the rolling seat 26 through a linkage shaft 91. The linkage shafts of the left and right guide rails are connected by a synchronization rod. When one of the fourth sliders 7 moves, it will push the fifth slider to move, or use the fifth slider to pull the fourth slider in the opposite direction to move, so that the side wall of the fifth slider 8 is provided with a tripping slope 81 and the reverse push slope 72 set on the side wall of the fourth slider 7 is contacted, and the fourth slider 7 is pushed to swing, so that the fourth slider is separated from the slide, and the guide rail is rebounded and opened.

[0054] Compared with traditional technology, this case achieves precise synchronization control through the design of synchronous gears and linkage shafts. The synchronous gear meshes with the rack on the fifth slider and achieves synchronization on both sides through rotation. The linkage shaft not only supports the rotation of the synchronous rack, but also ensures the accuracy and reliability of the synchronous operation.

[0055] Through this series of complex and sophisticated mechanical interactions, the invention can achieve highly synchronized rebound on both sides of the drawer guide, thereby significantly improving the user experience and solving the synchronization problem in traditional guide systems.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims created by the present invention.
