Description

Technical Field

[0001] This utility model relates to the field of cabinet furniture technology, specifically a support structure for cabinet furniture. Background Technology

[0002] With the continuous development of the times, furniture has evolved into a variety of types. Among them, cabinet furniture is very common in family life, mainly including wardrobes, bookcases, TV cabinets, storage cabinets, etc., which have multiple functions and design styles, and are generally made of wood as the main material.

[0003] Existing cabinet furniture typically has multiple support legs for support. However, when it is necessary to move cabinet furniture, it is inconvenient to move it because the furniture is relatively heavy, and its height is also fixed and not easy to adjust. Therefore, further improvements can be made. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a support structure for cabinet furniture, comprising a mounting frame, a base plate fixedly mounted on the bottom of the mounting frame, a lifting plate slidably connected inside the mounting frame, and furniture placed on the top side of the lifting plate inside the mounting frame. Three sets of protrusions are provided on both sides of the lifting plate. Limiting grooves are formed on the inner wall of the mounting frame corresponding to the three sets of protrusions, and the protrusions are slidably connected within the corresponding limiting grooves. A through hole is formed on the bottom side of the base plate. A height adjustment component for lifting and lowering is provided inside the mounting frame corresponding to the through hole. A transmission component for driving the height adjustment component is provided inside the mounting frame.

[0005] As an optimization, the height adjustment assembly includes a mounting plate fixedly installed on the inner wall of the mounting frame. A worm gear is rotatably connected to the middle of the mounting plate. A threaded cylinder is fixedly installed inside the worm gear. A screw is screwed into the threaded cylinder. A fixing seat is fixedly installed on the top of the screw, and the fixing seat is fixedly installed on the bottom side of the lifting plate.

[0006] As an optimization, a mounting base is fixedly installed at the bottom end of the screw, and a roller is rotatably connected inside the mounting base.

[0007] As an optimization, the outer diameter of the screw is smaller than the inner diameter of the through hole, which facilitates the screw's entry and exit.

[0008] As an optimization, the worm gear is internally connected to a bearing, and the bearing is fixedly installed between the two mounting plates.

[0009] As an optimization, the transmission assembly includes a support fixedly installed in the middle of the base plate, a rotating shaft rotatably connected to the top of the support, worms fixedly installed at both ends of the rotating shaft and between the two worm gears, and the worms meshing with the worm gears on both sides, and rocker arms fixedly installed at both ends of the rotating shaft through the mounting frame.

[0010] As an optimization, a bearing is installed inside the top of the support, and the rotating shaft is rotatably connected inside the bearing.

[0011] The beneficial effects of this utility model are:

[0012] This cabinet furniture uses a support structure. By turning the rocker arm clockwise, the worm gear rotates through the pivot, causing the worm wheel to rotate around the outside of the screw. This causes the screw to rise, which in turn causes the lifting plate to rise and fall synchronously, thus allowing the height of the furniture to be adjusted and improving its practicality. Similarly, by turning the rocker arm counterclockwise, the rollers are pressed against the ground and the mounting frame is lifted off the ground, allowing the furniture cabinet to be moved easily by rolling along the ground.

[0018] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 A support structure for cabinet furniture includes a mounting frame 1, a base plate 2 fixedly mounted on the bottom of the mounting frame 1, a lifting plate 3 slidably connected inside the mounting frame 1, and furniture placed on the top side of the lifting plate 3 inside the mounting frame 1. The lifting plate 3 has three sets of protrusions 4 on both sides. The inner wall of the mounting frame 1 corresponding to the three sets of protrusions 4 is provided with limit grooves 5, and the protrusions 4 are slidably connected in the corresponding limit grooves 5. The bottom side of the base plate 2 is provided with a through hole 6. The inside of the mounting frame 1 is provided with a height adjustment component 7 for lifting adjustment corresponding to the through hole 6. The inside of the mounting frame 1 is provided with a transmission component 8 for transmitting the height adjustment component 7.

[0021] Please see Figure 3-4 The height adjustment component 7 includes a mounting plate 9 fixedly installed on the inner wall of the mounting frame 1. A worm gear 10 is rotatably connected to the middle of the mounting plate 9. A bearing is rotatably connected inside the worm gear 10, and the bearing is fixedly installed between the two mounting plates 9. A threaded cylinder is fixedly installed inside the worm gear 10, and a screw 11 is screwed into the threaded cylinder. A fixing seat 12 is fixedly installed on the top of the screw 11, and the fixing seat 12 is fixedly installed on the bottom side of the lifting plate 3. The worm gear 10 is rotated by the transmission component 8, which causes the screw 11 inside to rise and fall. Therefore, the lifting plate 3 is raised and lowered synchronously, thereby adjusting the height of the furniture and improving its practicality.

[0022] Please see Figure 3-4 The outer diameter of the screw 11 is smaller than the inner diameter of the through hole 6, which facilitates the screw 11 to enter and exit. The bottom end of the screw 11 is fixedly installed with a mounting base 13. The mounting base 13 is rotatably connected to a roller 14. By rotating the worm gear 10, the screw 11 is driven to move downward, which will cause the roller 14 to press against the ground and lift the mounting frame 1 away from the ground. At this time, the furniture cabinet can be moved easily by rolling along the ground with the roller 14.

[0023] Please see Figure 3-4The transmission assembly 8 includes a support 15 fixedly installed in the middle of the base plate 2. A bearing is installed in the top of the support 15. A rotating shaft 16 is rotatably connected in the top of the support 15 and is rotatably connected in the bearing. Worms 17 are fixedly installed at both ends of the rotating shaft 16 and between the two worm gears 10. The worm gears 17 are meshed with the worm gears 10 on both sides. Rockers 18 are fixedly installed at both ends of the rotating shaft 16 through the mounting frame 1. By rocking the rockers 18, the rotating shaft 16 can be rotated, which in turn drives the worm gears 10 on both sides to rotate synchronously through the worm gears 17, thereby enabling the screw 11 to be driven to rise and fall.

[0024] When in use, first place the furniture cabinet into the mounting frame 1 and support it with the lifting plate 3. Then, turn the rocker arm 18 counterclockwise, which will drive the worm gear 17 to rotate through the rotating shaft 16. This will drive the worm wheel 10 to rotate around the outside of the screw 11, which will cause the internal screw 11 to descend. This will push the roller 14 against the ground and lift the mounting frame 1 away from the ground. At this time, the furniture cabinet can be moved to the designated position by rolling along the ground with the roller 14.

[0025] Once the furniture is moved to the designated position, the screw 11 will rise when the rocker arm 18 is turned clockwise, which will cause the lifting plate 3 to rise and fall synchronously, thus allowing the height of the furniture to be adjusted.

[0026] In summary, the support structure of this cabinet furniture allows for height adjustment by rotating the rocker arm 18 clockwise, which in turn drives the worm gear 17 via the pivot 16. This rotation causes the worm wheel 10 to rotate around the outside of the screw 11, raising the screw 11 and simultaneously raising and lowering the lifting plate 3. This improves the practicality of the furniture. Similarly, rotating the rocker arm 18 counterclockwise allows the rollers 14 to be pressed against the ground, lifting the mounting frame 1 away from the ground. This allows the furniture cabinet to be moved easily by rolling the rollers 14 along the ground.
