Description

Technical Field

[0001] This application relates to the field of drawer bottom rails, and in particular to a rebound bottom rail with an adjustable function. Background Technology

[0002] Press-to-open drawer slides offer high safety due to their child-proof design. They are typically equipped with dampers or rebound mechanisms for convenient operation, such as automatic slow-closing, press-to-open, and automatic pop-out. However, during actual installation, because the baffle is fixed to the sliding rail and the bottom rail is assembled into the drawer as a whole, the slide itself lacks a position adjustment mechanism. This makes it impossible to make direct fine adjustments after assembly, requiring a high level of skill from the installer. If the components are misaligned during installation, noticeable gaps can appear at the front and back of the drawer, affecting normal use and aesthetics. Adjusting the gaps requires adding a connector with an adjusting nut to the end of the sliding rail, making adjustment inconvenient. Utility Model Content

Detailed Implementation

[0027] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] 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.

[0030] The following is combined with Figures 1 to 10 The embodiments of this utility model are described below.

[0031] This application provides a rebound support rail with adjustable function, which includes a fixed rail 100 and a movable rail 200 movably connected thereto.

[0032] The adjustment assembly 300 includes a fixed base 310, an adjusting member, and a movable stop 330. The fixed base 310 is fixed on the movable rail 200, the adjusting member is disposed on the fixed base 310, and the movable stop 330 is pulsatorically connected to the adjusting member and has a baffle 331 that can extend out of the fixed base 310.

[0033] The rebound assembly 400 includes a base plate 410, a movable plate 420 slidably disposed on the base plate 410, an elastic member 430 for resetting the movable plate 420, and a rebound hook 440 hinged to the movable plate 420. An accommodating gap 401 for accommodating the baffle 331 is formed between the end of the rebound hook 440 and the movable plate 420, so that the position of the baffle 331 can be adjusted by rotating the adjusting member to drive the baffle 331 to move back and forth.

[0034] When a drawer is closed and there is a gap between it and the cabinet, such as a protruding or recessed door panel, the rotary adjustment mechanism (rotating knob 321) drives the movable stop 330 to move back and forth relative to the fixed base 310. This changes the position of the stop plate 331 in the front-to-back direction, creating a new front-to-back positioning point between the stop plate 331 and the receiving gap 401 of the rebound hook 440. When the drawer is closed again, the new positioning point aligns the front-to-back relative position of the drawer and the cabinet, eliminating the gap. Therefore, when it is necessary to adjust for a front-to-back gap in the drawer, the front-to-back position of the stop plate 331 can be fine-tuned using the adjustment mechanism. This allows for direct adjustment of the gap position, reducing misalignment and noise caused by the gap, and effectively reducing the assembly gap between the drawer and the cabinet in the front-to-back direction, ensuring the drawer door panel is flush with the cabinet. The elastic element 430 can be a tension spring, with both ends fixedly connected to the base plate 410 and the movable plate 420, respectively.

[0035] In some embodiments, the adjusting member includes a knob 321 and a transmission part 322 threadedly connected to the movable stop 330. By rotating the knob 321, the movable stop 330 can be moved, thereby adjusting the position of the baffle 331. Utilizing the threaded engagement between the transmission part 322 and the movable stop 330, rotating the knob 321 drives the movable stop 330 to move back and forth relative to the fixed base 310, thereby changing the position of the baffle 331 in the back-and-forth direction.

[0036] In some embodiments, the movable stop 330 is provided with a limiting protrusion 332, and the fixed base 310 is provided with a limiting groove 311. The limiting protrusion 332 and the limiting groove 311 are slidably engaged. The limiting protrusion 332 on the movable stop 330 and the limiting groove 311 on the fixed base 310 form a sliding engagement, which can limit the movable stop 330 to move only in the front-back direction, and avoid left-right deviation or misalignment.

[0037] In some embodiments, the base plate 410 is provided with a guide groove 411, and the rebound hook 440 is provided with a protrusion 441 that cooperates with the guide groove 411. This allows the movable rail 200 to slide along the guide groove 411 during movement, causing the rebound hook 440 to swing between the retracted position and the hook position. This ensures smooth sliding of the protrusion 441 along the guide groove 411, preventing the rebound hook 440 from getting stuck and improving the smoothness of drawer opening and closing. The guide groove 411 includes an arc-shaped segment 4111, a connecting segment 4112, and an elastic segment 4113 connected in sequence. The protrusion 441 slides in cooperation with the arc-shaped segment 4111, the connecting segment 4112, and the elastic segment 4113.

[0038] Specifically, when the drawer is pushed inward to close, the movable rail 200 gradually slides in, causing the baffle 331 to contact the sliding plate, pushing the sliding plate inward. The movable rail 200 drives the rebound hook 440 to move. The protrusion 441 on the rebound hook 440 slides along the arc-shaped section 4111 of the guide groove 411 of the bottom plate 410 into the connecting section 4112, driving the rebound hook 440 to swing upward around the hinge point to the hook position, keeping the baffle 331 within the receiving gap 401. When the drawer is opened, pressing the drawer causes the movable rail 200 to move in the opposite direction, and the protrusion 441 slides back along the connecting section 4112 to the arc-shaped section 4111. The rebound hook 440 swings downward and retracts, disengaging the baffle 331 from the receiving gap 401, thus enabling the drawer to open smoothly. Therefore, the arc-shaped section 4111 guides the rebound hook 440 downward to avoid gaps, and the connecting section 4112 guides the rebound hook 440 upward to lock it in place.

[0039] The elastic segment 4113 can be made of rubber, which can undergo elastic deformation when squeezed or subjected to force. When the protrusion 441 passes over the elastic segment 4113, the rebound hook 440 is in the lower, retracted position. When it passes over the connecting segment 4112 or when the elastic segment 4113 is not squeezed, the rebound hook 440 is in the upper, hooked position. When the drawer is closed and locked, the baffle 331 is between the moving plate 420 and the rebound hook 440. It is impossible to open the drawer by simply pulling the drawer slide out. If the drawer is forcibly pulled out, the baffle 331 will squeeze the rebound hook 440, causing the protrusion 441 on the rebound hook 440 to squeeze the elastic segment 4113, causing it to deform under pressure. This provides clearance for the protrusion 441, allowing the baffle 331 to slide out of the receiving gap 401 smoothly. After the baffle 331 slides out, the elastic segment 4113 returns to its original shape, and the protrusion 441 returns to its initial trajectory, without affecting the normal opening and closing of the subsequent drawers. This design protects the baffle 331 and the rebound hook 440 when the drawer is forcibly pulled out, preventing damage to the connecting parts due to pulling force and extending their service life. It also provides clearance while preventing the drawer from being unable to reset after being accidentally opened, ensuring normal use in the future.

[0040] Optionally, the elastic segment 4113 has at least one concave portion, and the base plate 410 has a relief opening 414 at a position corresponding to the concave portion. When the protrusion 441 presses the elastic segment 4113 on the guide groove 411, it can undergo elastic deformation under force, and at the same time, the relief opening 414 provides deformation space for the concave portion. Alternatively, the elastic segment 4113 can be made of rubber.

[0041] In some embodiments, the rebound assembly 400 further includes a hook 450, one end of which is hinged to the movable plate 420. The base plate 410 is also provided with a guide channel 412, and the other end of the hook 450 is provided with a guide portion 451 that slides in cooperation with the guide channel 412. Further, a guide block 413 is provided in the guide channel 412, which divides the guide channel 412 into a sliding section 4131, a blocking section 4132, and a sliding out section 4133 that are interconnected. The guide portion 451 can move along the sliding section 4131, the blocking section 4132, and the sliding out section 4133.

[0042] When the drawer is closed, the movable plate 420 moves inward along the movable rail 200, causing the pull hook 450 to move synchronously. The guide part 451 of the pull hook 450 slides inward along the sliding section 4131 of the guide channel 412 of the bottom plate 410. When the drawer is fully closed, the tension spring pulls the movable plate 420 back to its original position, and the guide part 451 enters the blocking section 4132 of the guide channel 412. The blocking section 4132 prevents the guide part 451 from moving outward, limiting the forward and backward displacement of the movable plate 420 and locking the drawer. When the drawer needs to be opened, press the drawer inward. The movable plate 420 moves inward against the tension spring force, causing the guide part 451 of the pull hook 450 to exit the blocking section 4132 of the guide channel 412 and enter the sliding section 4133. After the drawer is released, the tension spring pulls the movable plate 420 to slide outward, and the guide part 451 moves along the sliding section 4133, driving the movable rail 200 to move outward synchronously, thus opening the drawer by rebound.

[0043] In some embodiments, the rebound assembly 400 further includes a rebounder 460 disposed at the end of the base plate. Optionally, the rebounder includes a connecting cylinder, a connecting rod, and a spring. The connecting cylinder is fixed to the end of the base plate, the connecting rod is slidably inserted into the connecting cylinder with its end extending along the connecting cylinder towards the movable plate, and the spring is disposed within the connecting cylinder with its two ends abutting against the connecting rod and the inner wall of the connecting cylinder, respectively. When the drawer is closed, the movable plate moves towards the end of the base plate along the movable rail. The end of the movable plate contacts the connecting rod of the rebounder and pushes the connecting rod to slide into the connecting cylinder, compressing the spring within the connecting cylinder. When the movable plate reaches its maximum travel, the connecting rod cannot continue to slide, limiting excessive movement of the movable plate. When the drawer is pressed to open, the spring releases, pushing the connecting rod back to its original position. After the pull hook exits the blocking section, it drives the movable plate to move, thus cooperating with the pull spring to achieve the drawer's rebound opening. The extension and retraction stroke of the connecting rod is fixed. By limiting the contact with the movable plate, the maximum movement distance of the movable plate is limited, preventing it from colliding hard with the base plate or other components.

[0044] 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.
