Description

Technical Field

[0001] This application relates to the field of drawer slides, and in particular to a rebound component and a rebound bottom support rail. Background Technology

[0002] Rebound drawers primarily function through a rebound mechanism on the slide rails. There are two common types: one type features a soft-close function when closed, but requires manual pulling out of the drawer; the other type uses a touch-sensitive switch, where a light press automatically pops the drawer out. However, in actual use, users often overlook or omit the pressing operation and directly pull the drawer open. This misoperation not only reduces the user experience but may also damage the internal structure of the rebound mechanism and deform the guide rails, thus shortening the overall lifespan of the product.

[0025] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0026] The following is combined Figures 1 to 6 The embodiments of this utility model are described below.

[0027] This application provides a rebound component, which includes a base plate 100 and a guide groove 110 provided on its inner wall. The guide groove 110 includes a connecting section 111 and an elastic section 112 that are connected to each other.

[0028] A movable plate 200 is slidably connected to the base plate 100;

[0029] A rebound hook 300 is disposed between the base plate 100 and the movable plate 200. One end of the rebound hook 300 is rotatably connected to the movable plate 200, and the other end forms an accommodating gap 301 with the end of the movable plate 200. The accommodating gap 301 is used to accommodate external components. The rebound hook 300 is provided with a protrusion 310, which slides with the connecting section 111 and the elastic section 112, so that during the sliding process of the movable plate 200 relative to the base plate 100, the rebound hook 300 is driven to rotate around its rotating end and swing between the retracted position and the hooked position.

[0030] In actual assembly, the sliding rail 700 and the fixed rail 800 are slidably connected. A paddle 210 is fixed on the sliding rail 700. When the sliding rail 700 slides inward relative to the fixed rail 800, the paddle 210 moves with the sliding rail 700. When the paddle 210 contacts the rebound component, it pushes the moving plate 200 to move, thereby driving the protrusion 310 to move together along the connecting section 111 and the elastic section 112. When passing through the connecting section 111, the rebound hook 300 rotates to the hook position. In the hook position, a part of the rebound mechanism extends out of the moving plate 200 to form a hook structure. At the same time, the paddle 210 engages in the receiving gap 301.

[0031] After the sliding rail 700 slides inward to its final position, the elastic segment 112 is positioned adjacent to this final position. When the sliding rail 700 is forcibly pulled outward, the lever 210 applies force to the rebound hook 300 within the receiving gap 301, driving the protrusion 310 to squeeze the elastic segment 112 of the guide groove 110, causing it to deform. This forces the rebound hook 300 to rotate to the retracted position. In the retracted position, the end of the rebound hook 300 retracts into the moving plate 200 to avoid the lever 210, ensuring that the sliding rail 700 slides outward smoothly. After the lever 210 passes, the elastic segment 112 returns to its original shape under elastic action, and the rebound hook 300 resets accordingly, without affecting the normal push-pull use of the sliding rail 700 next time.

[0032] Therefore, by slidingly engaging the protrusion 310 with the connecting section 111 and the elastic section 112, the drawer can be opened even when the drawer is pulled outwards, thus protecting the slide rail 700 and the connecting accessories and effectively extending the durability and lifespan of the bottom rail.

[0033] In some embodiments, the elastic segment 112 includes at least one recess 1121, and the base plate 100 is provided with a clearance opening 101, with the recess 1121 and the clearance opening 101 corresponding to each other. By providing the clearance opening 101, the elastic structure of the recess 1121 is allowed to deform fully, so that after the elastic segment 112 is fully deformed, the rebound hook 300 can smoothly rotate to the retracted position, thereby adapting to scenarios with greater forced outward pulling force.

[0034] In some embodiments, the guide groove 110 further includes a retractable section 113, which is located at the end of the connecting section 111 away from the elastic section 112. The protrusion 310 is slidably connected to the retractable section 113, and the retractable section 113 is arc-shaped to guide the rebound hook 300 to move along the retracted position. When the sliding rail 700 is normally pulled out, the moving plate 200 drives the paddle 210 to move in the opposite direction. The protrusion 310 slides from the connecting section 111 into the retractable section 113. When the protrusion 310 contacts the retractable section, guided by the arc contour of the retractable section 113, the rebound hook 300 is driven to rotate around the rotating end. The rebound hook is pulled back to the retracted position, the rebound hook 300 retracts, and the paddle 210 slides out from the receiving gap 301, so that the sliding rail 700 can be smoothly pulled out.

[0035] In some embodiments, a hook 400 is further provided between the base plate 100 and the movable plate 200. The hook 400 includes a retaining ring portion 410 and a hook portion 420 connected to each other. The retaining ring portion 410 is rotatably connected to the movable plate 200. The guide groove 110 includes a guide channel 114, which is located at the end of the elastic segment 112 away from the connecting segment 111. The hook portion 420 is slidably connected to the guide channel 114 so that the hook portion 420 moves along the guide channel 114. The sliding portion slides relative to the base plate 100, allowing the hook portion 420 of the hook 400 to slide within the guide channel 114. The sliding fit structure between the hook 400 and the guide channel 114 is compact and does not occupy additional space.

[0036] In some embodiments, the guide channel 114 is provided with a guide block 115, which divides the guide channel 114 into a sliding section 1141, a blocking section 1142 and a sliding section 1143 that are interconnected. The hook portion 420 can move along the sliding section 1141, the blocking section 1142 and the sliding section 1143.

[0037] Specifically, when the sliding part slides inward relative to the base plate 100, the hook part 420 first moves along the sliding section 1141 of the guide channel 114. Guided by the contour of the sliding section 1141, the hook part 420 slides. As the sliding continues, the hook part 420 eventually slides into the blocking section 1142. The blocking section 1142 has a groove or bayonet structure, which locks the hook part 420, restricting its further movement and preventing the slide rail 700 from sliding inward. At this time, the drawer is stably locked in a preset position.

[0038] When the drawer needs to be fully pulled out, the user applies an inward pressing force. This action causes the slide rail 700 and the moving plate 200 to shift, thereby changing the position of the hook part 420 relative to the guide channel 114. This aligns the outlet of the blocking section 1142 with the hook part 420, allowing the hook part 420 to disengage from the groove or latch. Under its own weight or elastic force, the hook part 420 quickly rotates into the sliding section 1143. Once the hook part 420 is in the sliding section 1143, the drawer can be pulled outwards further. The hook part 420 moves within the sliding section 1143 without obstruction until the slide rail 700 slides back to the sliding section 1141 position, at which point the moving plate 200 and the hook 400 return to their original positions.

[0039] In some embodiments, the base plate 100 is further provided with a tension spring 500, the two ends of which are fixedly connected to the base plate 100 and the movable plate 200, respectively. The sliding rail 700 drives the movable plate 200 to slide along the base plate 100, stretching the tension spring 500. After the sliding rail 700 stops moving, the tension spring 500 generates a reverse pulling force, pulling the movable plate 200 back to its initial position quickly. Thus, by providing the tension spring 500, it is ensured that the movable plate 200 can quickly and accurately return to its relative position with the base plate 100 after sliding.

[0040] This application also provides a rebound support rail, which includes a fixed rail 800, a sliding rail 700, and a rebound component as described in the above embodiments. The fixed rail 800 and the sliding rail 700 are slidably connected, and the base plate 100 is fixed on the fixed rail 800. Since this rebound support rail uses the rebound component disclosed in the embodiments of this application, it also possesses the technical advantages of the rebound component disclosed in the embodiments of this application, which will not be described in detail in the embodiments of this application.

[0041] In some optional embodiments, the rebound bottom rail also includes a connector 600 for adjusting the height of the drawer. The connector 600 has a connector base and a handle connected to each other. The top of the handle has a limiting protrusion, and the other side of the connector 600 has a protrusion. The end and side of the slide rail have a first connecting hole and a second connecting hole, respectively. The protrusion is used to engage with the first connecting hole, and the limiting protrusion is used to engage with the second connecting hole. When assembling the connector and the slide rail, firstly, the protrusion on one side of the connector base is engaged with the first connecting hole at the end of the slide rail. The protrusion and the first connecting hole are then engaged. Next, the handle on the other side of the connector base is twisted so that the limiting protrusion on the top of the handle engages with the second connecting hole on the side of the slide rail, so that the handle is engaged with the slide rail by twisting. When disassembling, the wrench is twisted in the opposite direction so that the limiting protrusion disengages from the second connecting hole, and the handle base can be quickly removed without bolts, screws or other fasteners.

[0042] The preferred embodiments of the present invention have been described in detail above, but the present disclosure is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present disclosure.
