Description

Technical Field

[0001] This utility model relates to the field of rebound device technology, specifically a novel rebound device. Background Technology

[0002] With the increasing popularity of smart home and minimalist home design, push-to-open mechanisms, as key hardware accessories for opening and closing cabinet doors, drawers, and other furniture, are being used more and more widely in kitchen cabinets, wardrobes, and smart storage systems. Their concealed design achieves a "handle-less" aesthetic while meeting the need for convenient opening and closing, making them an important trend in modern home design.

[0003] Traditional rebounders mostly use only a single spring to achieve the reset function, lacking an effective buffer mechanism. When the rebound component is triggered by an external force, the spring rapidly releases energy, causing the component to eject at high speed, which can easily generate a violent impact sound and increase the risk of component wear. Especially in high-frequency use scenarios, this may cause safety hazards such as noise pollution and component fatigue fracture. To solve this problem, the inventors have proposed a novel rebounder. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned technologies, this utility model provides a novel rebound device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel rebound device, comprising a rebound component, a limiting component, a buffer component, and a quick-release component. The limiting component is disposed on the inner sidewall of the rebound component to facilitate limiting the rebound component. The buffer component is disposed on the inner sidewall of the limiting component to facilitate buffering the rebound component. The quick-release component is disposed at one end of the rebound component to facilitate quick release of the rebound component. The buffer component includes a gear, a rack, a rotary damper, and a limiting shaft. The gear is disposed on the inner sidewall of the limiting component, the rack is disposed on the inner sidewall of the rebound component and connected to the gear, the rotary damper is disposed on the inner sidewall of the gear, and the limiting shaft is disposed at one end of the rotary damper. The quick-release component includes a base plate body and a buckle. The base plate body is disposed at one end of the rebound component to facilitate cooperation with the rebound component, and the buckle is disposed at one end of the base plate body to facilitate quick release of the rebound component.

[0006] As further explained, the buffer assembly includes a spring disposed on the upper surface of the limiting assembly to facilitate the reset of the limiting assembly.

[0007] As further explained, the limiting component includes a hook body and a hook base. The hook base is located at one end of the rebound component, the hook body is located on the inner sidewall of the hook base and the limiting component, and the spring is located on the upper surface of the hook base.

[0008] As a further explanation, it also includes a main support and a shaft hole body. The main support is located on the inner sidewall of the rebound assembly, the shaft hole body is formed on the inner sidewall of the main support, and the gear is located on the inner sidewall of the main support.

[0009] As a further explanation, one end of the main support is provided with a thread to facilitate the limiting of the rebound component, and one end of the main support is provided with a positioning groove corresponding to the thread. The iron hook body is respectively located on the inner sidewall of the iron hook base and the positioning groove.

[0010] As a further explanation, it also includes a slot, which is provided on the inner sidewall of the rebound component to facilitate the limiting of the rebound component.

[0011] As further explained, the rebound assembly includes a core cylinder, an adjusting rod, and a rubber pad. The adjusting rod is located at one end of the core cylinder and is threadedly connected. The rubber pad is located at one end of the adjusting rod. The rack is located on the inner wall of the core cylinder. The iron hook base is located at one end of the core cylinder. The main support is located on the inner wall of the core cylinder. The slot is located on the inner wall of the core cylinder to facilitate engagement with a buckle. The base plate body is located at one end of the core cylinder.

[0012] As further explained, the quick-release assembly includes a mounting hole, a rotating groove, and a rotating shaft. The mounting hole is formed on the inner side wall of the base plate body, the rotating groove is formed on the inner side wall of the base plate body, and the rotating shaft is located between the core cylinder and the rotating groove to facilitate angle adjustment of the core cylinder.

[0013] In summary, this utility model has the following beneficial effects: The novel rebound device of this utility model employs a three-stage linkage structure of gear-rack-rotary damper in its buffer assembly, with precise positioning via a limiting shaft. When the adjusting rod is pushed, the spring drives the main support to move linearly, simultaneously triggering the gear rotary damper to move along the rack, generating controllable resistance. This effectively slows down the ejection speed and avoids the problems of spring fatigue, hook wear, and reduced rebound force caused by rapid impact in traditional spring-hook structures.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-5 As shown, this utility model discloses a novel rebound device, comprising a rebound component, a limiting component, a buffer component, and a quick-release component. The limiting component is located on the inner wall of the rebound component to facilitate limiting the rebound component. The buffer component is located on the inner wall of the limiting component to facilitate buffering the rebound component. The quick-release component is located at one end of the rebound component to facilitate quick release of the rebound component. The buffer component includes a gear 301, a rack 302, a rotary damper 303, a spring 31, and a limiting shaft 304. The gear 301 is located on the inner wall of the limiting component, the rack 302 is located on the inner wall of the rebound component and connected to the gear 301, the rotary damper 303 is located on the inner wall of the gear 301, the limiting shaft 304 is located at one end of the rotary damper 303, and the spring 31 is located on the upper surface of the limiting component to facilitate resetting the limiting component.

[0021] Specifically, during the continuous pushing process of the adjusting rod 12, the rack 302 on the inner wall of the core cylinder 11 moves synchronously with the core cylinder 11, driving the gear 301 meshing with it to rotate. The rotation damper 303 on the inner wall of the gear 301 is fixed in the shaft hole body 211 of the main support 210 through the limiting shaft 304. When the gear 301 rotates, it drives the rotation damper 303 to rotate synchronously. The rotation damper 303 generates a damping force through a viscous fluid or friction structure, applying reverse resistance to the rotation of the gear 301, thereby slowing down the moving speed of the rack 302. During this stage, the compression of the spring 31 and the damping force of the rotation damper 303 work together to achieve a smooth buffering of the pressing process.

[0022] The quick-release assembly includes a base plate body 41 and a buckle 43. The base plate body 41 is located at one end of the rebound assembly to facilitate cooperation with the rebound assembly. The buckle 43 is located at one end of the base plate body 41 to facilitate quick release of the rebound assembly.

[0023] The limiting component includes a hook body 201 and a hook base 202. The hook base 202 is located at one end of the rebound component. The hook body 201 is located on the inner sidewalls of both the hook base 202 and the limiting component. A spring 31 is located on the upper surface of the hook base 202. The component also includes a main support 210 and a shaft hole body 211. The main support 210 is located on the inner sidewall of the rebound component, and the shaft hole body 211 is formed on the inner sidewall of the main support 210. A gear 301 is located on the inner sidewall of the main support 210. One end of the main support 210 has a thread 212 for limiting the rebound component. Another end of the main support 210 has a positioning groove 213 corresponding to the thread 212. The hook body 201 is located on the inner sidewalls of both the hook base 202 and the positioning groove 213. The component also includes a retaining groove 21, located on the inner sidewall of the rebound component for limiting the rebound component.

[0024] Specifically, the hook body 201 in the limiting assembly re-enters the positioning groove 213 during the spring 31's reset process, completing the mechanical locking. The hook base 202 engages with the threaded end 212 of the main support 210, and the stroke is adjusted via the threaded connection 212 of the adjusting rod 12. The rubber pad 13 provides cushioning contact at the end of the adjusting rod 12 to avoid rigid impact. The slot 21 engages with the snap 43 of the quick-release assembly to ensure a secure connection between the core cylinder 11 and the base plate body 41.

[0025] The rebound assembly includes a core cylinder 11, an adjusting rod 12, and a rubber pad 13. The adjusting rod 12 is located at one end of the core cylinder 11 and is connected to a thread 212. The rubber pad 13 is located at one end of the adjusting rod 12. The rack 302 is located on the inner wall of the core cylinder 11. The iron hook base 202 is located at one end of the core cylinder 11. The main support 210 is located on the inner wall of the core cylinder 11. The slot 21 is located on the inner wall of the core cylinder 11 to facilitate cooperation with the buckle 43. The base plate body 41 is located at one end of the core cylinder 11.

[0026] Specifically, when an external force pushes the adjusting rod 12, the adjusting rod 12 drives the core cylinder 11 to move inward. At this time, the hook body 201, located on the inner wall of the hook base 202 and the positioning groove 213, slides within the positioning groove 213 of the main support 210. When it moves to the disengagement critical point, the hook body 201 disengages from the positioning groove 213, releasing the axial restriction on the main support 210. Simultaneously, the spring 31 on the upper surface of the hook base 202 is compressed and stores energy, providing reset power for subsequent ejection.

[0027] The quick-release assembly includes a mounting hole 44, a rotating groove 42, and a rotating shaft 45. The mounting hole 44 is opened on the inner side wall of the base plate body 41, the rotating groove 42 is opened on the inner side wall of the base plate body 41, and the rotating shaft 45 is located between the core cylinder 11 and the rotating groove 42 to facilitate the angle adjustment of the core cylinder 11.

[0028] Specifically, the core cylinder 11 is fixed by the mounting holes 44 on the base plate body 41, and the rotating shaft 45 rotates within the rotating groove 42 to achieve angle adjustment. The buckle 43 is designed to allow for quick disassembly: when maintenance is required, the buckle 43 is operated to release the core cylinder 11, and the rotating shaft 45, in conjunction with the rotating groove 42, allows the core cylinder 11 to rotate around the axis, facilitating quick removal from the installation position.
