Description

Technical Field

[0001] This utility model relates to the field of furniture, specifically to a drawer locking adjustment device. Background Technology

[0002] Drawers are commonly found in various furniture such as tables and cabinets, used for storing items. To overcome the problems of traditional drawers, such as high friction, easy falling off, and difficulty in fully opening, most existing drawers are modular, installed on the furniture via movable slides. These slides consist of fixed and movable rails that move relative to each other, connected to the furniture and the drawer respectively, allowing the drawer to be easily pulled in or out of the furniture's drawer. With the diversification of furniture designs, to improve the convenience of furniture maintenance and cleaning, more and more drawers adopt detachable structures. However, there are often some assembly errors between the drawer and the slides during assembly and disassembly, thus requiring an adjustment mechanism between the drawer and the slides. For example, Chinese Patent CN102326978B provides a locking and adjusting mechanism for drawer slides. It has a connecting seat and a locking rod installed on the drawer, and a locking hole on the slide. Assembly and disassembly are achieved by the locking tongue on the locking rod interlocking with the locking hole. An adjusting block is slidably mounted on the connecting seat. By turning an adjusting dial connected to the adjusting block, the extension length of the adjusting block can be changed, thereby adjusting the height of the drawer's front panel. However, the aforementioned locking and adjusting mechanism only has an adjustment mechanism for the height of the drawer. Its adjustable direction is limited, the adjustment accuracy is poor, and the operation is inconvenient. It cannot be directly applied to the adjustment in other directions. Therefore, when there is a precision error between the drawer and the slide rail, it will still cause the drawer panel to not fit against the drawer when the drawer is closed, or the drawer to not be fully opened, thus affecting the overall aesthetics of the furniture and the user experience, and making it difficult to meet the user's needs for adjusting the drawer position. Utility Model Content

[0003] The purpose of this utility model is to overcome the problems existing in the prior art and provide a drawer locking and adjusting device that is easy to install and disassemble, stable, and can adjust the installation position of the drawer relative to the furniture in different directions, so as to better meet the user's needs for adjusting the position of the drawer.

[0004] The drawer locking and adjusting device of this utility model includes a main board fixedly installed at the bottom of the drawer, a locking mechanism for locking the drawer onto the movable rail, and a front-back adjusting mechanism, a left-right adjusting mechanism, and a top-bottom adjusting mechanism for adjusting the relative front-back position of the drawer and the movable rail. The top-bottom adjusting mechanism is installed on the main board. The front-back adjusting mechanism includes front-back adjusting wheels and a panel. The front-back adjusting wheels are rotatably installed on the main board, and their ends have front-back adjusting screws pointing axially to the front and back sides of the drawer. The panel is movably installed on the main board in the front-back direction and has front-back threaded portions that are threadedly connected to the front-back adjusting screws. The left-right adjusting mechanism includes left-right adjusting wheels and left-right adjusting plates. The left-right adjusting wheels are rotatably installed on the panel and their ends have left-right adjusting screws pointing axially to the left and right sides of the drawer. The left-right adjusting plates are movably installed on the panel in the left-right direction and have left-right threaded portions that are threadedly connected to the left-right adjusting screws. One side of the left-right adjusting plate also has a fixing fork that engages with the front end of the movable rail. The locking mechanism is installed on the left-right adjusting plates.

[0005] The drawer locking adjustment device is installed at the bottom of the drawer, and a track assembly consisting of fixed rails and movable rails is installed on the cabinet of the furniture. The main board of the drawer locking adjustment device is fixed to the drawer, and it has a locking mechanism that can lock the drawer on the movable rail and an adjustment mechanism that can be adjusted in three directions. The drawer features a locking mechanism to lock or separate the sliding rail from the drawer. A height-adjustment mechanism mounted on the main board adjusts the relative height of the drawer and the sliding rail. A left-right adjustment mechanism uses a fixed fork to engage with the front end of the sliding rail, fixing the sliding rail and the adjustment plates relative to each other. Left-right adjustment wheels are mounted on the panel, and their ends are connected to the left and right threads on the adjustment plates via adjusting screws. Rotating the adjustment wheels causes the adjusting screws to rotate, moving the adjustment plates relative to the panel in the left-right direction, and the sliding rail moves along with them, thus allowing the drawer to move left and right relative to the sliding rail. Similarly, a front-back adjustment mechanism uses front-back adjustment wheels mounted on the main board, connected to the front and back threads on the panel via adjusting screws. Rotating the front-back adjustment wheels causes the adjusting screws to rotate, moving the panel and the adjustment plates along the sliding rail's extension direction relative to the main board, and the sliding rail moves along with the adjustment plates, thus allowing the drawer to move back and forth relative to the sliding rail.

[0006] Therefore, by setting up the above structure, the drawer is connected to the movable rail on the slide assembly via the main board, panel, left and right adjustment plates, and the installation position of the drawer relative to the movable rail in the front-back and left-right directions can be adjusted by the front-back and left-right adjustment wheels respectively. The vertical adjustment mechanism adjusts the vertical relative position of the drawer and the movable rail. When the drawer does not correspond to the opening of the furniture drawer in the left-right or front-back directions, or when the positions of different drawers are not aligned, the adjustment wheels of the corresponding adjustment mechanism can be rotated to change the relative position between the drawer and the movable rail, thereby aligning the drawer with the opening of the furniture drawer, or making each drawer level with each other, improving the overall aesthetics of the furniture, and meeting the user's needs for adjusting the position of the drawer in multiple directions. Moreover, the above-mentioned adjustment wheels are adjusted and controlled by screw transmission, which is simple in structure and easy to operate, making the adjustment process of the drawer in various directions smoother, improving the user experience, and making the adjustment more precise, ensuring the accuracy of drawer installation.

[0007] Furthermore, the main board has a first square opening for partially exposing the front and rear adjustment wheels; the panel has a first receiving groove that covers the front and rear adjustment wheels, and the length of the first receiving groove in the front-rear direction is greater than the thickness of the front and rear adjustment wheels.

[0008] Furthermore, the panel has a second square opening for partially exposing the left and right adjustment wheels; the left and right adjustment plates are provided with a second receiving groove that covers the left and right adjustment wheels, and the length of the second receiving groove in the left and right direction is greater than the thickness of the left and right adjustment wheels.

[0009] Furthermore, the up-down adjustment mechanism includes an up-down adjustment plate that can be horizontally moved and mounted on the main board. The main board is also equipped with an up-down adjustment wheel with teeth or spiral patterns. The up-down adjustment plate is provided with toothed stripes or threads that are threadedly connected to the up-down adjustment wheel. The front end of the up-down adjustment plate is also provided with an adjustment ramp that can be inserted between the movable rail and the drawer bottom plate.

[0010] Furthermore, the motherboard has a third-party shaped opening for partially exposing the up and down adjustment wheels.

[0011] Furthermore, the locking mechanism includes an elastic element, a handle hinged to the left and right adjustment plates, and a locking pin that slides with the left and right adjustment plates. The head end of the locking pin is provided with a fastening part that can be inserted into the lock hole of the movable rail, and the tail end of the locking pin is connected to the left and right adjustment plates through the elastic element. The force exerted by the elastic element on the locking pin causes the fastening part to engage with the lock hole. The outer end of the handle faces away from the drawer, and the inner end of the handle is provided with a driving part. The locking pin is provided with a driving groove for the driving part to engage.

[0012] Furthermore, the side of the latch facing outwards from the drawer has several stepped teeth, while the side facing away from the drawer has an inclined or curved guide surface. Attached Figure Description

[0029] This utility model proposes a drawer locking adjustment device.

[0030] like Figure 1-15As shown in the embodiment of this utility model, the drawer locking adjustment device includes a main board 1 fixedly installed at the bottom of the drawer 200, a locking mechanism for locking the drawer 200 onto the movable rail 302, and a front-to-back adjustment mechanism, a left-to-right adjustment mechanism, and a top-to-bottom adjustment mechanism for adjusting the relative front-to-back position of the drawer 200 and the movable rail 302. The top-to-bottom adjustment mechanism is installed on the main board 1. The front-to-back adjustment mechanism includes front-to-back adjustment wheels 2 and a panel 3. The front-to-back adjustment wheels 2 are rotatably installed on the main board 1, and their ends have front-to-back adjustment screws 21 axially pointing towards the front and rear sides of the drawer 200. The panel 3 is axially... The rearward-movable adjustment mechanism is mounted on the main board 1. The panel 3 has front and rear threaded portions 31 that are threadedly connected to the front and rear adjustment screws 21. The left and right adjustment mechanism includes left and right adjustment wheels 4 and left and right adjustment plates 5. The left and right adjustment wheels 4 are rotatably mounted on the panel 3, and their ends have left and right adjustment screws 41 pointing axially to the left and right sides of the drawer 200. The left and right adjustment plates 5 are movably mounted on the panel 3 in the left and right direction. The left and right adjustment plates 5 have left and right threaded portions 51 that are threadedly connected to the left and right adjustment screws 41. A fixing fork 52 that engages with the front end of the movable rail 302 is also provided on one side of the left and right adjustment plates 5. The locking mechanism is mounted on the left and right adjustment plates 5. The above drawer locking adjustment device is described in reference to... Figure 11 , Figure 12 As shown, it is installed at the bottom of drawer 200. Correspondingly, a track assembly consisting of fixed rail 301 and movable rail 302 is installed on the cabinet 100 of the furniture. The main board 1 of the drawer locking adjustment device can be fixed to the bottom surface of drawer 200 by fixing screws. It has a locking mechanism that can lock drawer 200 on movable rail 302 and an adjustment mechanism that can be adjusted in three directions to adjust the installation position of drawer 200 relative to movable rail 302.

[0031] In the left and right adjustment mechanism, the left and right adjustment plate 5 is engaged with the front end of the movable rail 302 via a fixed fork 52, thereby fixing the movable rail 302 and the left and right adjustment plate 5 relative to each other; for example Figure 6 , 7As shown, the left and right adjustment wheels 4 are mounted on the panel 3, and the left and right adjustment wheels 4 are connected to the left and right threaded parts 51 on the left and right adjustment plates 5 by the left and right adjustment screws 41 at the ends. When the left and right adjustment wheels 4 are rotated, the left and right adjustment screws 41 rotate accordingly, causing the left and right adjustment plates 5 to move in the left and right direction relative to the panel 3. The movable rail also moves with the left and right adjustment plates 5, thereby realizing the left and right movement of the drawer relative to the movable rail. To facilitate user adjustment, the panel 3 also has a second square opening 12 for partially exposing the left and right adjustment wheels 4. The second square opening 12 can be located on the side of the panel 3 facing away from the bottom of the drawer. The left and right adjustment plate 5 is provided with a second receiving groove 53 that covers the left and right adjustment wheels 4. The length of the second receiving groove 53 in the left and right direction is greater than the thickness of the left and right adjustment wheels 4. The second receiving groove 53 covers the part of the left and right adjustment wheels 4 that is not exposed from the second square opening 12, so as to reduce the accumulation of dust and foreign objects due to excessive exposed parts. The length of the second receiving groove 53 in the left and right direction can be adjusted according to actual needs to adapt to the range of left and right movement of the left and right adjustment plate 5 relative to the panel 3.

[0032] When the drawer's horizontal installation position is found to be inaccurate, for example, if the drawer does not correspond to or align with the cabinet drawer opening in the left-right direction, the portion of the left-right adjusting wheel 4 exposed in the second square opening 12 can be moved. The left-right adjusting wheel 4 drives the left-right adjusting screw 41 at its end to rotate. Since the axis of the left-right adjusting screw 41 points to the left and right sides of the drawer, it can move relative to the left-right adjusting plate 5 through the left-right threaded part 51. This allows the left-right adjusting plate 5 to move left and right relative to the panel 3 and the main plate 1. The left-right adjusting plate 5 drives the movable rail to move along with it through the fixed fork 52, which in turn drives the drawer to move left and right relative to the movable rail, adjusting the drawer to the appropriate position. Using the above-mentioned left-right adjusting mechanism, the drawer can be adjusted horizontally conveniently and quickly. It is also compact, simple in structure, and easy to operate. The threaded transmission method of the left-right adjusting screw 41 and the left-right threaded part 51 can drive the drawer to move smoothly and accurately.

[0033] The front-to-back adjustment mechanism adopts a similar structure to the left-to-right adjustment mechanism, such as... Figure 8-10As shown, the front and rear adjusting wheels 2 are mounted on the main board 1, and the front and rear adjusting wheels 2 are meshed and threaded with the front and rear threaded parts 31 on the panel 3 through the front and rear adjusting screws 21 at the ends. When the front and rear adjusting wheels 2 are rotated, the front and rear adjusting screws 21 rotate accordingly, causing the panel 3 and the left and right adjusting plates 5 located on the panel 3 to move back and forth along the extension direction of the movable rail relative to the main board 1. The movable rail also moves along with the left and right adjusting plates 5, thereby realizing the back and forth movement of the drawer relative to the movable rail. To facilitate user adjustment, the mainboard 1 also has a first square opening 11 for partially exposing the front and rear adjustment wheels 2. The first square opening 11 can be set on the side of the mainboard 1 facing away from the bottom of the drawer. The panel 3 is provided with a first receiving groove 32 that covers the front and rear adjustment wheels 2. The length of the first receiving groove 32 in the front-to-back direction is greater than the thickness of the front and rear adjustment wheels 2. The first receiving groove 32 covers the part of the front and rear adjustment wheels 2 that is not exposed from the first square opening 11, so as to reduce the accumulation of dust and foreign objects due to excessive exposed parts. The length of the first receiving groove 32 in the front-to-back direction can be adjusted according to actual needs to adapt to the range of front and rear movement of the panel 3 relative to the mainboard 1.

[0034] When the drawer does not align with the cabinet opening in the front-to-back direction, or when the front-to-back positions of adjacent drawers are not aligned, the portion of the front-to-back adjusting wheel 2 exposed in the first square opening 11 can be moved. The front-to-back adjusting wheel 2 drives the front-to-back adjusting screw 21 at its end to rotate. Since the axis of the front-to-back adjusting screw 21 points towards the front and back sides of the drawer, it can move relative to the panel 3 through the front and back threaded part 31, causing the panel 3 to move back and forth relative to the main board 1. The left and right adjusting plates 5 on the panel 3 also move back and forth accordingly, and through the fixed fork 52, they drive the movable rail to move, thus causing the drawer to move back and forth relative to the movable rail, adjusting the drawer to the appropriate position. Using the above-mentioned front-to-back adjusting mechanism, the drawer can be adjusted in the direction of the movable rail extension conveniently and quickly. It is also compact, simple in structure, and easy to operate. The threaded transmission method of the front-to-back adjusting screw 21 and the front and back threaded part 31 can drive the drawer to move smoothly and accurately.

[0035] In the above structure, the drawer is connected to the movable rail on the slide assembly via the main board 1, panel 3, and left / right adjustment plate 5, combining the front-to-back and left-to-right adjustment mechanisms. The front-to-back adjustment of the drawer is achieved by the front-to-back movement of panel 3 relative to the main board 1, and the left-to-right adjustment of the drawer is achieved by the left-to-right movement of the left / right adjustment plate 5 relative to panel 3. This further simplifies the components of the locking and adjusting device. Figure 9A cover plate 14 can be fastened to the side of the main board 1 near the bottom of the drawer to reduce the exposed parts of the locking adjustment device and further prevent malfunctions caused by dust accumulation or foreign objects entering. In addition, all components can be injection molded, with simple mold design and simple component structure, making installation convenient; the left and right adjustment wheels 4 and the front and rear adjustment wheels 2 can be designed with the same size structure, making the adjustment wheels interchangeable and reducing production costs.

[0036] The locking mechanism is used to lock or release the movable rail from the drawer. Specifically, such as... Figure 4-6 As shown, the locking mechanism includes an elastic element 10, a handle 9 hinged to the left and right adjustment plates 5, and a locking pin 8 that slides with the left and right adjustment plates 5. The head end of the locking pin 8 is provided with a fastening part 81 that can be inserted into the locking hole 15 of the movable rail 302. The tail end of the locking pin 8 is connected to the left and right adjustment plates 5 through the elastic element 10. The elastic element 10 can be a spring. The force exerted by the elastic element 10 on the locking pin 8 causes the fastening part 81 to engage with the locking hole 15. The outer end of the handle 9 faces away from the drawer. The inner end of the handle 9 is provided with a driving part 91. The locking pin 8 is provided with a driving groove 82 for the driving part 91 to engage with.

[0037] The above structure can be referenced. Figure 11-13 As shown, the lock holes 15 are located on the opposite sides of the two movable rails 302, and two corresponding locking adjustment devices are symmetrically installed on the bottom of the drawer to simultaneously lock or unlock with the two movable rails 302. The locking mechanism is installed on the left and right adjustment plates 5, so that its handles 9 and other components are well hidden at the bottom of the drawer between the two movable rails, reducing accidental operation caused by accidental collisions and improving the aesthetics of the drawer. The side of the latching part 81 facing outwards has several stepped teeth 811, which facilitates the connection of the latching part 81 with drawers and rail assemblies of different sizes, improving applicability. The side facing away from the drawer has an inclined or curved guide surface 812, making the contact and relative movement between the latching part 81 and the front end of the movable rail 302 smoother. When installing the drawer, as... Figure 11 The drawer is inserted along the sliding rail. When the locking pin 8 on the locking mechanism moves with the drawer to the front end of the sliding rail 302, the guide surface 812 on the engaging part 81 of the locking pin 8 contacts the front end of the sliding rail 302. The engaging part 81 is blocked and squeezed by the front end of the sliding rail 302, causing the locking pin 8 to be forced inward and the elastic element 10 to be compressed. The drawer continues to move until the locking pin 8 moves to the position opposite to the lock hole 15 on the sliding rail 302. Under the action of the elastic element 10, the locking pin 8 springs back, causing its engaging part 81 to insert into the lock hole 15 of the sliding rail 302. (Reference) Figure 14As shown in state b, the fixed fork 52 on the left and right adjustment plates 5 is also fixedly engaged with the end of the movable rail 302, thus facilitating and quickly installing the drawer onto the movable rail 302, fixing the drawer and the movable rail relatively. After the drawer is installed, when the drawer is pulled outward, the locking mechanism moves together with the main plate 1, and the stepped teeth 811 on the latching part 81 abut against the inner wall of the lock hole 15 on the movable rail 302, which can effectively prevent the locking rod from falling off the lock hole 15, thereby driving the movable rail to move outward and preventing the drawer from detaching from the movable rail and falling off. When it is necessary to disassemble the drawer, refer to... Figure 14 As shown in state a, pressing the handle 9 moves the locking pin 8 inward, compressing the elastic element 10. The engaging part 81 of the locking pin 8 disengages from the locking hole 15 of the movable rail 302, allowing the drawer to be pulled outward and disengaged from the movable rail 302. This structure effectively prevents the drawer from detaching from the rail assembly, improves their connection stability, and is simple and convenient to use.

[0038] The vertical adjustment mechanism is mounted on the main board 1, and it can adjust the relative vertical position of the drawer and the sliding rail. Specifically, as shown... Figure 10 As shown, the height adjustment mechanism includes a height adjustment plate 6 horizontally movably mounted on a main board 1. The main board 1 also has height adjustment wheels 7 with teeth or spiral patterns. The height adjustment plate 6 has toothed stripes or threads 61 that are threadedly connected to the height adjustment wheels 7. The front end of the height adjustment plate 6 also has an adjustment ramp 62 that can be inserted between the sliding rail and the drawer bottom plate. By utilizing the different thicknesses of the adjustment ramp 62 at different positions, the depth to which the height adjustment plate 6 is inserted between the sliding rail and the drawer bottom plate can be changed, thereby altering the gap between them. The main board 1 also has a third-dimensional opening 13 for partially exposing the height adjustment wheels 7, allowing for user adjustment. (Reference) Figure 15 As shown, when the vertical direction of drawer 200 does not correspond to the opening of furniture cabinet 100, the vertical adjustment plate 6, which is threadedly connected to the vertical adjustment wheel 7 and protruding from the third-dimensional opening 13, can be moved horizontally by adjusting the vertical adjustment wheel 7. The adjustment slope 62 located at the front end of the vertical adjustment plate 6 can be inserted between the bottom surface of drawer 200 and the top surface of movable rail 302. The insertion depth of adjustment slope 62 can be changed by adjusting the vertical adjustment wheel 7, thereby changing the gap between movable rail and drawer bottom plate, that is, adjusting the vertical position of drawer 200 relative to movable rail 302.

[0039] This drawer locking and adjusting device locks the sliding rail to the drawer via a locking mechanism, enabling quick drawer installation. The drawer's position relative to the sliding rail in these directions can be adjusted using the front-back, left-right, and up-down adjusting wheels. When the drawer does not align with the cabinet drawer opening in these directions, or when different drawers are not aligned, the adjusting wheels in the corresponding directions can be rotated to change the relative position between the drawer and the sliding rail. This aligns the drawer with the cabinet drawer opening or makes each drawer level with the others. Its simple structure and convenient operation enhance the overall aesthetics of the furniture, satisfying users' needs for multi-directional drawer adjustment and improving the user experience. Furthermore, the adjusting wheels use a screw-driven control system, making adjustments to the drawer in all directions smoother and more precise, thus ensuring accurate drawer installation.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
