Description

Technical Field

[0001] This utility model relates to the technical field of slide rails, and in particular to an easily adjustable slide rail assembly and drawer. Background Technology

[0002] Currently, drawers are generally installed inside cabinets using slide rails, relying on these rails for smooth opening and closing. However, during actual installation, accumulated dimensional tolerances in cabinet components or the drawers themselves often lead to misalignment or interference between the drawer panel and adjacent doors / frames in the vertical direction, affecting usability and creating an unsightly appearance. In existing technology, traditional adjustment methods rely on the operator manually tightening the adjusting bolts connecting the drawer and the slide rails. This method has significant limitations: it is not only cumbersome and time-consuming, but also lacks positioning feedback during adjustment, making it impossible to fix and reproduce the adjustment parameters. Furthermore, drawer vibration or shaking can easily loosen the adjusting bolts, causing positional shifts and resulting in poor adjustment effectiveness. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Reference Figures 1 to 4According to a first aspect of the present invention, an adjustable slide rail assembly includes a slide rail base 100, a sliding member 200, an adjustment component 300, and a multi-stage positioning structure. The sliding member 200 is slidably connected to the slide rail base 100 and can slide along the extension direction of the slide rail base 100. The adjustment component 300 includes an adjustment seat 310 and an adjustment knob 320. The adjustment seat 310 is fixedly connected to the sliding member 200, and the adjustment knob 320 is rotatably connected to the top of the adjustment seat 310. The top of the adjustment knob 320 is used to abut against the bottom of the drawer 600. The adjustment seat 310 is provided with a first spiral platform 311, and the adjustment knob 320 is provided with a second spiral platform 321. When the adjustment knob 320 is rotated, the first spiral platform 311 and the second spiral platform 321 can be driven to move the adjustment knob 320 in the up and down direction. The multi-stage positioning structure is provided on the adjustment seat 310 and the adjustment knob 320, and the multi-stage positioning structure can position the adjustment knob 320 in multiple rotational positions. Specifically, the slide rail base 100 can extend in the front-to-back direction and can be connected inside the cabinet 500. The sliding member 200 is slidably connected to the slide rail base 100; the specific sliding connection structure is not limited here. A drawer 600 can be installed on the sliding member 200, and the bottom of the drawer 600 abuts against the top surface of the adjusting knob 320. Under the action of gravity, the drawer 600 can press the adjusting knob 320 against the top of the adjusting seat 310. When the adjusting knob 320 is rotated, the adjusting knob 320 rises and falls, thereby driving the drawer 600 to move up and down. Furthermore, the multi-stage positioning structure can position the adjusting knob 320 to maintain the current adjustment position, and the positioned position can be replicated. It can be understood that when replacing different drawers 600, the adjusting knob 320 can be rotated to the corresponding rotation position according to the type of drawer 600, facilitating use.

[0036] With the above structure, when the adjustment knob 320 is rotated, the first spiral stage 311 and the second spiral stage 321 can be driven to move the adjustment knob 320 up and down, thereby driving the drawer 600 to adjust up and down. During operation, the multi-stage positioning structure can sequentially position the adjustment knob 320 at different rotation positions, providing feedback to the operator on the positioning position. When the drawer 600 needs to be disassembled or replaced, it can be directly positioned according to the required position without repeated adjustments. Furthermore, the multi-stage positioning structure can position the rotation position of the adjustment knob 320, limiting the rotational deviation of the adjustment knob 320 under shaking or vibration of the drawer 600, resulting in good adjustment effect.

[0037] Reference Figures 3 to 4In some embodiments of this utility model, the multi-level positioning structure includes positioning protrusions 410 and positioning grooves 420. Multiple positioning protrusions 410 and / or positioning grooves 420 are provided. Positioning grooves 420 are provided on the helical surface of one of the first spiral platform 311 and the second spiral platform 321, and positioning protrusions 410 are provided on the helical surface of the other spiral platform. Positioning protrusions 410 can be engaged with positioning grooves 420. Specifically, positioning grooves 420 can be provided on the adjusting seat 310, and positioning protrusions 410 can be provided on the adjusting knob 320. Positioning grooves 420 can be spaced apart along the helical surface of the first spiral platform 311. One positioning protrusion 410 can be provided on the helical surface of the second spiral platform 321, or multiple positioning protrusions 410 can be provided, spaced apart along the helical surface of the second spiral platform 321. When the adjustment knob 320 is rotated, the positioning protrusions 410 can be sequentially engaged in the positioning grooves 420 to form multiple positioning positions. After the positioning protrusions 410 are engaged with the positioning grooves 420, the adjustment knob 320 will not deflect when the drawer 600 shakes or vibrates, resulting in good positioning effect.

[0038] It is understandable that the positioning groove 420 can be located on the adjustment knob 320 or the adjustment seat 310, which can also achieve multi-level snap-fit ​​positioning.

[0039] Reference Figures 3 to 4 In some embodiments of this utility model, the multi-level positioning structure further includes multiple positioning grooves 430 and elastic teeth 440. The multiple positioning grooves 430 are sequentially arranged on the periphery of the adjusting knob 320, and the elastic teeth 440 are arranged on the adjusting seat 310. When the adjusting knob 320 is rotated, the elastic teeth 440 can sequentially engage with each positioning groove 430. Specifically, the adjusting knob 320 is approximately circular in shape, and the positioning grooves 430 are sequentially arranged around the rotation axis of the adjusting knob 320. The number of positioning grooves 430 can be the same as the number of positions of the aforementioned positioning grooves 420. The elastic teeth 440 are located on one side of the positioning grooves 430 and can engage with the positioning grooves 430 under elastic force. When the adjusting knob 320 is rotated, the elastic teeth 440 can disengage from the current positioning groove 430 and engage with the next positioning groove 430. The cooperation between the elastic teeth 440 and the positioning grooves 430 further enhances the multi-level positioning effect.

[0040] It is conceivable that when the elastic tooth 440 engages with the positioning tooth groove 430, the positioning protrusion 410 simultaneously engages with the positioning groove 420. Through the cooperation of the above two sets, the positioning effect can be further improved.

[0041] Reference Figure 3In some embodiments of this utility model, the elastic tooth 440 includes a vertical portion 441 and a tooth portion 442. The tooth portion 442 is located on the upper part of the vertical portion 441 and protrudes towards the adjustment knob 320. A clearance groove 443 is provided on the side of the vertical portion 441 away from the adjustment knob 320. Specifically, the shape of the tooth portion 442 matches that of the positioning tooth groove 430. During operation, the vertical portion 441 can deform towards the clearance groove 443 so that the tooth portion 442 disengages from the current positioning tooth groove 430. When rotating to the next positioning position, the vertical portion 441 can drive the tooth portion 442 to engage in the next positioning tooth groove 430 under the action of elastic force, thereby achieving automatic positioning and convenient operation.

[0042] Reference Figure 2 and Figure 4 In some embodiments of this utility model, the adjusting knob 320 is further provided with a first limiting groove 451 and a second limiting groove 452 on its peripheral wall. Multiple positioning tooth grooves 430 are located between the first limiting groove 451 and the second limiting groove 452. The first limiting groove 451 and the second limiting groove 452 can cooperate with the elastic tooth 440 to limit the rotation range of the adjusting knob 320. Specifically, the groove depth of the first limiting groove 451 and the second limiting groove 452 can be set to be deeper. When the elastic tooth 440 is engaged in the first limiting groove 451 and the second limiting groove 452, it can prevent the elastic tooth 440 from dislodging from the current limiting groove, and can limit the elastic tooth 440 to only engage within the range of the positioning tooth groove 430. This, in turn, limits the rotation range of the adjusting knob 320, preventing excessive rotation that could cause the adjusting knob 320 to dislodge or become jammed.

[0043] Reference Figures 2 to 4 In some embodiments of this utility model, the adjusting seat 310 includes a first mounting groove 312 with the opening facing upward. The first mounting groove 312 has a first guide hole 313 extending in the vertical direction in the middle. The adjusting knob 320 has a rotating shaft 322 at the bottom. The rotating shaft 322 has a locking block 3221 around its circumference. The rotating shaft 322 can be inserted into the first guide hole 313. The locking block 3221 can restrict the rotating shaft 322 from coming out of the first guide hole 313. Specifically, the adjusting seat 310 can be installed on the top of the sliding member 200, and the first mounting groove 312 with the opening facing upward is used to install the adjusting knob 320. The rotating shaft 322 of the adjusting knob 320 can be inserted into the first guide hole 313 for cooperation, and the locking block 3221 can prevent the adjusting knob 320 from coming out of the adjusting seat 310 after it is locked into the first guide hole 313, which facilitates assembly. The adjusting knob 320 can rotate around the axis of the first guide hole 313. It can be understood that the first spiral platform 311 and the second spiral platform 321 are both spirally arranged around the above-mentioned rotation axis.

[0044] Reference Figure 4In some embodiments of this utility model, the rotating shaft 322 is provided with a through groove 3222 that penetrates the side wall radially, and two locking blocks 3221 are provided, with the two locking blocks 3221 located on both sides of the through groove 3222 respectively. Specifically, the through groove 3222 facilitates the deformation of the locking blocks 3221, facilitates the insertion of the rotating shaft 322 into the first guide hole 313, and further facilitates the insertion of the adjusting knob 320 into the adjusting seat 310.

[0045] Reference Figure 4 In some embodiments of this utility model, a lever 323 is provided on the side of the adjustment knob 320. The lever 323 facilitates the operator to rotate the adjustment knob 320.

[0046] Reference Figures 5 to 7 In some embodiments of this utility model, the sliding member 200 is further provided with an upwardly extending guide post 210, and the bottom of the drawer 600 is provided with a second guide hole 610 extending in the vertical direction, with the guide post 210 inserted into the second guide hole 610. Specifically, when the drawer 600 is installed, the guide post 210 is inserted into the second guide hole 610 for cooperation, and the guide post 210 and the second guide hole 610 can only move in the vertical direction relative to each other, thereby restricting the drawer 600 from moving in the vertical direction.

[0047] Reference Figures 5 to 7 According to a second aspect embodiment of the present invention, the drawer 600 includes a drawer 600 employing the aforementioned adjustable slide rail. By employing the aforementioned adjustable slide rail, the drawer 600 can be easily adjusted in the vertical direction during use, and the adjusted position can be stable, resulting in good adjustment effect.
