Description

Technical Field

[0001] This utility model relates to the field of hardware furniture technology, and more specifically, to a connection and adjustment device for a drawer slide assembly and a drawer. Background Technology

[0002] Drawers can be hidden inside a cabinet of drawers for storing items. They are usually pulled out using a sliding rail system. However, due to precision errors during the manufacturing or assembly of cabinets of drawers, the height and left-right positions of the drawers may not correspond. In the case of built-in drawers, the front-to-back position of the drawers may also be inconsistent. Therefore, it is necessary to install an adjustment device between the drawer and the sliding rail to adjust the position of the drawer relative to the sliding rail. This will adjust the relative position of the drawer and the cabinet of drawers, so as to achieve smooth opening and closing of the drawer and good closure between the drawer and the cabinet of drawers, avoiding excessive gaps.

[0003] Existing adjustment devices generally only allow for height and lateral adjustment of the drawer relative to the cabinet, but not for front-to-back adjustment. While the drawer can move back and forth relative to the cabinet via slide rails during use, it lacks front-to-back position adjustment and cannot control the distance between the drawer's outer end and the cabinet after it is closed. This is especially true for built-in drawers, which may result in large gaps or the drawer being embedded too deeply into the cabinet, exposing the sides of the cabinet. This affects both the drawer's functionality and aesthetics. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing adjustment devices that cannot simultaneously adjust the front-back, left-right, and up-down positions of the drawer relative to the drawer cabinet. It provides a connection adjustment device and drawer for a drawer slide assembly, which can adjust the position of the drawer relative to the drawer cabinet from three different dimensions, thereby achieving a good match between the drawer and the drawer cabinet, smooth pulling, and improving the sealing and aesthetics of the drawer after closing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A connection adjustment device for a drawer slide assembly is provided, the adjustment device being fixedly mounted on the drawer and detachably connected to the slide assembly; the adjustment device includes...

[0007] A fixed base is fixedly installed in the drawer and movably connected to the slide rail assembly;

[0008] A first direction adjustment component is movably mounted on the fixed base and is used to adjust the moving position of the fixed base relative to the slide rail assembly in the first direction.

[0009] The second direction adjustment component is movably mounted on the fixed base and is used to adjust the moving position of the fixed base relative to the slide rail assembly in the second direction.

[0010] The third-direction adjustment component is movably mounted on the fixed base and is used to adjust the moving position of the fixed base relative to the slide rail assembly in the third direction.

[0011] Wherein, the first direction, the second direction, and the third direction are all perpendicular to each other.

[0012] The first, second, and third directions of this utility model can be the front-back, left-right, and up-down directions of the drawer relative to the drawer cabinet, respectively. There are no specific limitations on the first, second, and third directions; they can be interchanged, as long as each of the three directions is perpendicular to the others. The adjusting device is fixedly connected to the drawer using a mounting bracket. Then, the first, second, and third direction adjusting components are used to adjust the three dimensions, allowing the drawer to adjust its position relative to the slide rail assembly, and thus its position relative to the drawer cabinet. This achieves a good fit between the drawer and the drawer cabinet, ensuring smooth operation and improving the sealing and aesthetics of the drawer when closed.

[0013] Furthermore, the first direction adjustment component includes a first driving part and a first transmission part both movably mounted on the fixed base; the second direction adjustment component includes a second driving part and a second transmission part both movably mounted on the fixed base; and the third direction adjustment component includes a third driving part and a third transmission part both movably mounted on the fixed base. The first transmission part, the second transmission part, and the third transmission part all abut against the slide rail assembly. Rotating the first driving part causes the first transmission part to drive the fixed base to move back and forth relative to the slide rail assembly in a first direction; rotating the second driving part causes the second transmission part to drive the fixed base to move back and forth relative to the slide rail assembly in a second direction; and rotating the third driving part causes the third transmission part to drive the fixed base to move back and forth relative to the slide rail assembly in a third direction. A first drive unit provides driving force, and a first transmission unit, driven by the first drive unit, can move back and forth along a first direction, thereby causing the fixed seat to move relative to the slide rail assembly. A second drive unit provides driving force, and a second transmission unit, driven by the second drive unit, can move back and forth along a second direction, thereby causing the fixed seat to move relative to the slide rail assembly. A third drive unit provides driving force, and a third transmission unit, driven by the third drive unit, can move back and forth along a third direction, thereby causing the fixed seat to move relative to the slide rail assembly. Within the understanding of those skilled in the art, each drive unit and each transmission unit cooperates with each other, corresponding one-to-one, to jointly achieve the change of the fixed seat's position.

[0014] Furthermore, the first transmission part is provided with a first abutting part, the second transmission part is provided with a second abutting part, the third transmission part is provided with a third abutting part, and the slide rail assembly is provided with a fourth abutting part, a fifth abutting part, and a sixth abutting part respectively. The first abutting part abuts against the fourth abutting part, the second abutting part abuts against the fifth abutting part, and the third abutting part abuts against the sixth abutting part. The first abutting part can be a protrusion, and the fourth abutting part can be a groove, or they can be interchanged. The second abutting part and the fifth abutting part can also adopt a similar structure, or they can adopt a structure in which inclined surfaces cooperate with each other. Preferably, the first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction. The third abutting part can be a wedge-shaped structure, and the sixth abutting part can be an inclined plane, using the third abutting part to push the sixth abutting part to move up or down.

[0015] Furthermore, the first driving part is a first nut, the first transmission part is a first screw, and the first nut is threadedly connected to the first screw; the second driving part is a second nut, the second transmission part is a second screw, and the second nut is threadedly connected to the second screw; the third driving part is a third screw, the third transmission part is a third nut, and the third nut is threadedly connected to the third screw. The engagement of the first screw and the first nut, the engagement of the second nut and the second screw, and the engagement of the third nut and the third screw all adopt the principle of lead screw and nut transmission, converting rotation into linear movement output to achieve positional movement of the fixed seat in the first, second, and third directions. Within the scope of knowledge of those skilled in the art, the structure of the lead screw and nut can also be replaced by a gear and rack, gear meshing, or electric cylinder or hydraulic cylinder transmission structure.

[0016] Furthermore, the second direction adjustment assembly also includes an adapter seat and a guide rod. The adapter seat is connected to the fixed seat. The adapter seat has a guide hole and a mounting hole parallel to each other. The second abutment portion is located at the end of the second screw. The guide rod is arranged parallel to the second screw and its end is connected to the second abutment portion. The guide rod also movably passes through the guide hole. The second nut is movably mounted on the adapter seat. The second screw passes through the mounting hole and is threadedly connected to the second nut. The adapter seat is used for installing the second nut and the second screw. The cooperation between the guide rod and the guide hole achieves a guiding function. Rotating the second nut causes the second screw to move in the second direction, thereby driving the second abutment portion to move. Then, the abutment portion of the second abutment portion and the fifth abutment portion of the slide rail assembly push the drawer relative to the slide rail assembly to move in the second direction.

[0017] Furthermore, the third-direction adjustment assembly also includes a sliding part, which is movably mounted on the fixed base and partially protrudes from the fixed base. The sliding part has a first sliding groove, the third abutment part is located at the end of the sliding part, and the third nut has a slider, which is slidably connected to the first sliding groove. To save installation space, the third screw rotates, causing the third nut to move, thereby driving the slider to move along the first sliding groove, so that the sliding part moves relative to the fixed base. Then, through the abutment of the third abutment part and the sixth abutment part, the fixed base moves relative to the slide rail assembly in the third direction. Unlike the first-direction adjustment assembly and the second-direction adjustment assembly, the third driving part is a screw and the third transmission part is a nut, which can save more installation space. If there is enough space, the third driving part can also be set as a nut, the third transmission part can be set as a screw, and the third abutment part can be set on the screw. When the nut is rotated, the screw moves, thereby causing the third abutment part to drive the sixth abutment part to move relative to each other.

[0018] Furthermore, it also includes a latch assembly, which includes a latch, a lever, and a spring element. The latch is movably mounted on the fixed base, and the spring element is mounted on the latch and abuts against the fixed base. The lever is rotatably connected to the fixed base and movably engaged with the latch. Rotating the lever can move the latch relative to the fixed base to adjust its position protruding from the fixed base. The latch can engage with the slide rail assembly. By moving the lever, it can swing relative to the fixed base, thereby adjusting the length of the latch protruding from the fixed base. Under the action of the spring element, the latch can maintain an outward protrusion. A groove is provided on the slide rail assembly. When the latch is inserted into the groove, it can engage with the slide rail assembly. At this time, the latch assembly is in a locked state, and the fixed base is engaged with the slide rail assembly. When unlocking is required, moving the lever will retract the latch, and then moving the fixed base will move the fixed base away from the slide rail assembly, allowing the drawer to be disassembled.

[0019] This utility model also provides a drawer, including a drawer cabinet with a hollow cavity, a drawer body, and a slide rail assembly. The drawer body is slidably connected to the drawer cabinet via the slide rail assembly. The bottom of the drawer body is equipped with a connection adjustment device for the drawer slide rail assembly as described above, and the drawer body engages with the slide rail assembly. The adjustment device allows for adjustment of the position of the drawer body relative to the slide rail assembly, thereby ensuring a good fit between the drawer body and the drawer cabinet, smooth draw and pull, and improved sealing and aesthetics of the drawer when closed.

[0020] Furthermore, the slide rail assembly includes a fixed part and a movable part. The fixed part is fixedly installed on the inner side wall of the hollow cavity of the drawer cabinet. The movable part is engaged with the adjustment device of the drawer slide rail assembly and slidably connected to the fixed part. The fixed part and the movable part slide together to achieve a sliding connection between the drawer body and the drawer cabinet. The position of the fixed part relative to the movable part can be adjusted using the adjustment device, thereby adjusting the position of the drawer body relative to the drawer cabinet to achieve good fit of the drawer body in the front-back, left-right, and up-down directions.

[0021] Furthermore, an adjusting block is installed at the end of the movable part, the fourth abutting part and the sixth abutting part are both located on the adjusting block, and the fifth abutting part is located on the fixed part. The adjusting device, through the cooperation of the first direction adjusting component, the third direction adjusting component and the adjusting block, enables the fixed seat to move in the left-right and up-down directions relative to the movable part, and through the cooperation of the second direction adjusting component and the fixed part, enables the fixed seat to move in the front-back direction relative to the fixed part.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The adjustment device is fixedly connected to the drawer using a fixed base. Then, the three dimensions are adjusted by the first direction adjustment component, the second direction adjustment component, and the third direction adjustment component, so that the position of the drawer relative to the slide rail component can be adjusted, and thus the position of the drawer relative to the drawer cabinet can be adjusted, so as to achieve good cooperation between the drawer and the drawer cabinet, smooth opening and closing, and improve the sealing and aesthetics of the drawer after closing.

[0044] Example 1

[0045] like Figures 1 to 13 The diagram shows Embodiment 1 of a connection adjustment device for a drawer slide assembly according to this utility model. The adjustment device is fixedly installed in the drawer and detachably connected to the slide assembly 6. The adjustment device includes...

[0046] Fixed base 1 is fixedly installed in the drawer and movably fastened to the slide rail assembly 6;

[0047] The first direction adjustment component 2 is movably mounted on the fixed base 1 and is used to adjust the moving position of the fixed base 1 relative to the slide rail assembly 6 in the first direction.

[0048] The second direction adjustment component 3 is movably mounted on the fixed base 1 and is used to adjust the moving position of the fixed base 1 relative to the slide rail assembly 6 in the second direction.

[0049] The third-direction adjustment component 4 is movably mounted on the fixed base 1 and is used to adjust the moving position of the fixed base 1 relative to the slide rail assembly 6 in the third direction.

[0050] Among them, the first direction is perpendicular to the second direction and the third direction.

[0051] Specifically, the first direction adjustment assembly 2 includes a first drive part 21 and a first transmission part 22, both movably mounted on the fixed base 1; the second direction adjustment assembly 3 includes a second drive part 31 and a second transmission part 32, both movably mounted on the fixed base 1; and the third direction adjustment assembly 4 includes a third drive part 41 and a third transmission part 42, both movably mounted on the fixed base 1. The first transmission part 22, the second transmission part 32, and the third transmission part 42 all abut against the slide rail assembly 6. Rotating the first drive part 21 can cause the first transmission part 22 to drive the fixed base 1 to move back and forth relative to the slide rail assembly 6 in the first direction; rotating the second drive part 31 can cause the second transmission part 32 to drive the fixed base 1 to move back and forth relative to the slide rail assembly 6 in the second direction; and rotating the third drive part 41 can cause the third transmission part 42 to drive the fixed base 1 to move back and forth relative to the slide rail assembly 6 in the third direction. Furthermore, the first transmission part 22 is provided with a first abutting part 221, the second transmission part 32 is provided with a second abutting part 321, the third transmission part 42 is provided with a third abutting part 421, and the slide rail assembly 6 is provided with a fourth abutting part 631, a fifth abutting part 611, and a sixth abutting part 632 respectively. The first abutting part 221 abuts with the fourth abutting part 631, the second abutting part 321 abuts with the fifth abutting part 611, and the third abutting part 421 abuts with the sixth abutting part 632. Even further, the first driving part 21 is a first nut, the first transmission part 22 is a first screw, and the first nut is threadedly connected to the first screw; the second driving part 31 is a second nut, the second transmission part 32 is a second screw, and the second nut is threadedly connected to the second screw; the third driving part 41 is a third screw, the third transmission part 42 is a third nut, and the third nut is threadedly connected to the third screw.

[0052] The fixed base 1 has a second sliding groove 11 along the left-right direction, and the first abutment part 221 can slide within the second sliding groove 11. Rotating the first driving part 21 causes the first transmission part 22 to drive the first abutment part 221 to move back and forth left and right within the second sliding groove 11. The first abutment part 221 is a protrusion, and the fourth abutment part 631 is a groove. The first driving part 21 is rotatably mounted on the fixed base 1. Rotating the first nut drives the first abutment part 221 to move horizontally left and right parallel within the second sliding groove 11 on the fixed base 1 via the first screw. At this time, the first abutment part 221 abuts against the fourth abutment part 631 provided on the slide rail assembly 6 and drives the slide rail assembly 6 to move in the same direction. However, the slide rail assembly 6 is fixedly set, so the fixed base 1 can move relative to the slide rail assembly 6 in the left-right direction.

[0053] In one embodiment of this utility model, the second direction adjustment assembly 3 further includes an adapter 33 and a guide rod 34. The adapter 33 is connected to the fixed base 1. The adapter 33 has a guide hole 331 and a mounting hole 332 arranged parallel to each other. The second abutment part 321 is located at the end of the second screw. The guide rod 34 is arranged parallel to the second screw and its end is connected to the second abutment part 321. The guide rod 34 is also movably inserted through the guide hole 331. The second nut is movably mounted on the adapter 33. The second screw passes through the mounting hole 332 and is threadedly connected to the second nut. The bottom of the adapter 33 has a square column, and the fixed base 1 has a corresponding hole or groove. The fixed base 1 and the adapter 33 are fastened together. The guide rod 34 passes through the guide hole 331 and can move back and forth relative to the guide hole 331 to achieve a guiding function. The second screw is threadedly connected to the second nut, and the second nut is rotatably positioned on the adapter 33. The bottom of the second abutment 321 has a protrusion, and the fixing base 1 has a third sliding groove 12 along the front-back direction. The protrusion is reciprocally positioned in the third sliding groove 12 on the fixing base 1, which also serves as a guide. Rotating the second nut causes the second screw to move the second abutment 321 and the protrusion back and forth along the third sliding groove 12. The second abutment 321 contacts the fifth abutment 611 on the slide rail assembly 6. Continuing to rotate the second nut in the same direction causes the second screw to continue moving, increasing the distance between the adjusting device and the slide rail assembly 6. Rotating the second nut in the opposite direction causes the second screw to move in the opposite direction, decreasing the distance between the adjusting device and the slide rail assembly 6 until the second abutment 321 separates from the fifth abutment 611, thereby enabling the drawer to move relative to the drawer cabinet 7 in the front-back direction.

[0054] As one embodiment of the present invention, the third-party directional adjustment component 4 further includes a sliding part 43, which is movably mounted on the fixed base 1 and can partially protrude from the fixed base 1. The sliding part 43 is provided with a first sliding groove 431, a third abutting part 421 is located at the end of the sliding part 43, and a third nut is provided with a slider 422, which is slidably connected to the first sliding groove 431.

[0055] The third screw is threadedly connected to the third nut, which is reciprocally positioned within the fixed base 1. The third screw is rotatably positioned within the fixed base 1 and can move back and forth relative to the fixed base 1. The slider 422 is a cylindrical structure and is slidably connected to the third slide groove 12 provided on the sliding part 43. The fixed base 1 is provided with a fourth slide groove 13 along the front-back direction, and the sliding part 43 can reciprocate back and forth within the fourth slide groove 13 of the fixed base 1. Rotating the third screw causes the slider 422 of the third nut to move within the first slide groove 431 of the sliding part 43, while the sliding part 43 can be driven to move within the fourth slide groove 13 on the fixed base 1. When the sliding part 43 extends out of the notch provided on the fixed base 1, the third abutment part 421 abuts against the sixth abutment part 632 on the slide rail assembly 6. Preferably, the third abutment part 421 and the sixth abutment part 632 are mutually cooperating inclined surfaces. The continued extension of the sliding part 43 causes the fixed base 1 to move upward relative to the slide rail assembly 6. Rotating the third screw in the opposite direction causes the third nut to rotate, which in turn moves the slider 422 in the opposite direction. The sliding part 43 also moves in the opposite direction, causing the fixed seat 1 to move downwards relative to the drawer cabinet 7, thereby achieving the adjustment of the drawer's vertical position relative to the drawer cabinet 7.

[0056] Example 2

[0057] This embodiment is a second embodiment of a connection adjustment device for a drawer slide assembly. This embodiment is similar to embodiment 1, except that, as shown in the example... Figure 14 and Figure 15 As shown, it also includes a locking assembly 5, which includes a locking tongue 51, a lever 52, and an elastic element 53. The locking tongue 51 is movably mounted on the fixed base 1, and the elastic element 53 is mounted on the locking tongue 51 and abuts against the fixed base 1. The lever 52 is rotatably connected to the fixed base 1 and movably inserted into the locking tongue 51. Rotating the lever 52 can drive the locking tongue 51 to move relative to the fixed base 1 to adjust its position protruding from the fixed base 1. The locking tongue 51 can be engaged with the slide rail assembly 6.

[0058] The latch 51 is movably placed inside the fixed base 1. One end of the elastic element 53 abuts against the side wall inside the fixed base 1, and the other end abuts against the latch 51. A mounting part 511 is provided on the latch 51, and a protrusion is provided on the elastic element 53, so that the protrusion of the elastic element 53 is engaged and fixed in the mounting part 511 of the latch 51. The lever 52 has a through hole, and the fixed base 1 has a rotating shaft 16. The through hole of the lever 52 cooperates with the rotating shaft 16 to realize the rotational connection of the lever 52 relative to the fixed base 1. The fixed base 1 has a receiving part 14, into which the latch 51 is inserted. The receiving part 14 has an opening 15, and the length of the latch 51 protruding from the opening 15 is adjustable.

[0059] One end of the lever 52 abuts against the inclined surface of the latch 51 and can be inserted into the latch 51. Moving one end of the lever 52 causes it to rotate around the fixed base 1, while the other end rotates in the opposite direction, causing the latch 51 to move relative to the fixed base 1. At this time, the adjusting device is separated from the slide rail assembly 6. After the slide rail assembly 6 contacts the inclined surface on the latch 51 and continues to move towards the adjusting device, the latch 51 is pressed into the receiving portion 14 on the fixed base 1 until the square hole 621 on the slide rail assembly 6 moves to the opening 15 on the fixed base 1. At this point, the elastic element 53 inside the latch 51 is released, ejecting the latch 51. After ejection, the latch 51 engages and is fixed with the slide rail assembly 6.
