Description

Technical Field

[0001] This utility model relates to the field of furniture drawers, and in particular to a flat drawer structure that does not require tracks. Background Technology

[0002] In traditional residential interior design and furniture design, cabinets (such as kitchen base cabinets) and shoe cabinets typically have a raised area of ​​10 to 15 centimeters at the bottom, commonly referred to in the industry as the "kick-off space" or "kick-off area." After the cabinets are installed, this area essentially becomes an unusable "idle space" or "blind spot." However, the application of "kick-off drawers" can reuse this unused space at the bottom of traditional cabinets. It involves embedding a set of low-height, deep, flat drawers (usually called "kick-off drawers" or "flat drawers") into the traditional kick-off space.

[0003] Currently, most kick kick drawers use a track-mounted installation method. Their fixed structure makes the installation process complex and requires professional operation, making it inconvenient for users to install or adjust them themselves. Furthermore, the kick kick drawer structure often requires manufacturers to customize the design and production for specific cabinet dimensions, resulting in poor adaptability and difficulty in flexibly matching different models and specifications of cabinets. Utility Model Content

[0004] This utility model provides a trackless flat panel drawer structure, which can solve the problems of existing trackless flat panel drawer structures that use track installation, have a complicated installation process, are inconvenient for users to install or adjust themselves, and have poor adaptability.

[0005] A trackless flat drawer structure includes a cabinet base plate, inside which is a flat plate. Multiple casters are evenly installed on the bottom of the flat plate. Two rear limiting components are symmetrically arranged on both sides of the flat plate near the rear. Each rear limiting component includes a rear limiting wheel and a first adjustment component. The first adjustment component is located on the cabinet base plate and is used to adjust the horizontal position of the rear limiting wheel. Two front limiting components are symmetrically arranged on both sides of the flat plate and near the front. The front limiting components include front limiting wheels and a second adjustment component. The second adjustment component is located on the bottom plate of the cabinet and is used to adjust the horizontal position of the front limiting wheels.

[0006] Preferably, the flat panel has a side panel on the side near the opening of the cabinet bottom panel, and the side panel has a baffle.

[0007] Preferably, the first adjustment assembly further includes a receiving groove formed on the bottom side of the plate, a first threaded rod disposed inside the receiving groove, and two first nuts threadedly connected to the first threaded rod. The first threaded rod passes through the interior of the plate and is fixedly connected to the rear limiting wheel. The first nuts are located on the side wall of the receiving groove and on the outside of the plate, respectively.

[0008] Preferably, the second adjustment assembly further includes a mounting plate fixed to the bottom plate of the cabinet, a second threaded rod fixed to the mounting plate, a connecting rod sleeved on the second threaded rod, and a third nut threadedly connected to the second threaded rod, wherein the front limit wheel is mounted on the end of the connecting rod.

[0009] Preferably, two guide grooves are symmetrically formed on the side plate, and a third threaded rod is inserted inside each guide groove. The third threaded rod is fixedly connected to the baffle, and a second nut is threaded onto each third threaded rod.

[0010] Preferably, anti-collision plates are fixed on both the side of the cabinet bottom plate behind the rear limit wheel and the side of the cabinet bottom plate in front of the front limit wheel.

[0011] Preferably, the anti-collision plate is provided with an elastic pad on the side near the rear limit wheel.

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1 to 6 As shown in the figure, the present invention provides a trackless flat drawer structure, including a cabinet base plate 1, a flat plate 2 inside the cabinet base plate 1, a plurality of casters 4 evenly installed on the bottom of the flat plate 2, two rear limiting components symmetrically arranged on both sides of the flat plate 2 near the rear side, the rear limiting components including rear limiting wheels 7 and a first adjustment component, the first adjustment component being disposed on the cabinet base plate 1 and used to adjust the horizontal position of the rear limiting wheels 7; two front limiting components symmetrically arranged on both sides of the flat plate 2 near the front side, the front limiting components including front limiting wheels 14 and a second adjustment component, the second adjustment component being disposed on the cabinet base plate 1 and used to adjust the horizontal position of the front limiting wheels 14, the front limiting wheels 14 and the rear limiting wheels 7 both cooperate with the sides of the flat plate 2 to roll and limit the flat plate 2.

[0021] When the flat panel 2 is installed in the cabinet base plate 1, if the size of the cabinet base plate 1 or the drawer area changes due to differences in cabinet design, the installer can independently adjust the horizontal positions of the two rear limit wheels 7 and the two front limit wheels 14 by operating the first adjustment component and the second adjustment component. Specifically, the first adjustment component moves the rear limit wheels 7 inward or outward to match the actual width of the rear side of the flat panel 2. Similarly, the second adjustment component adjusts the position of the front limit wheels 14 to ensure that the front and rear limit wheels accurately correspond to the edges on both sides of the flat panel 2. When the flat panel 2 is pulled out, the casters 4 provide support and movement, and the front and rear limit wheels limit the left and right positions of the flat panel 2 to ensure the smooth movement of the flat panel.

[0022] By adjusting the front and rear limit wheels and cooperating with the casters 4, installation can be completed quickly without matching and installing a fixed track, which is simple and improves installation efficiency. Moreover, by adjusting the front and rear limit wheels, the flat panel 2 can move smoothly in the cabinet bottom plate 1, which expands the applicability of the flat panel drawer structure, making it flexibly adaptable to different models and specifications of cabinets, improving its versatility and compatibility, and making it highly practical.

[0023] In some specific implementation plans, such as Figure 2 and Figure 5 As shown, the first adjustment assembly also includes a receiving groove 5 opened on the bottom side of the plate 2, a first threaded rod 6 disposed inside the receiving groove 5, and two first nuts 8 threadedly connected to the first threaded rod 6. The first threaded rod 6 passes through the interior of the plate 2 and is fixedly connected to the rear limiting wheel 7. The first nuts 8 are located on the side wall of the receiving groove 5 and the outside of the plate 2, respectively.

[0024] By loosening the first nut 8, the distance of the rear limit wheel 7 extending beyond the side of the flat plate 2 is adjusted, allowing the rear limit wheel 7 to roll in conjunction with the inner wall of the cabinet bottom plate 1. Tightening the first nut 8 locks the first threaded rod 6 in the desired position. By adjusting the position of the rear limit wheel 7 through the cooperation of the first threaded rod 6 and the first nut 8, the rear limit wheel 7 can better adapt to the installation of different sized drawer areas at the bottom of the cabinet.

[0025] In some specific implementation plans, such as Figure 1 , Figure 3 and Figure 6 As shown, the second adjustment assembly also includes a mounting plate 11 fixed on the cabinet bottom plate 1, a second threaded rod 12 fixed on the mounting plate 11, a connecting rod 13 sleeved on the second threaded rod 12, and a third nut 19 threadedly connected to the second threaded rod 12. The third nut 19 is located at the top of the connecting rod 13, and the front limit wheel 14 is installed at the end of the connecting rod 13.

[0026] The front limit assembly can further limit the horizontal movement of the plate 2. After the mounting plate 11 is fixed on the cabinet bottom plate 1, the distance between the connecting rod 13 and the front limit wheel 14 on it and the side of the plate 2 can be adjusted by loosening the third nut 19. This allows the front limit wheel 14 to better adapt to the installation of different sized drawer areas at the bottom of the cabinet. Tightening the third nut 19 to ensure good contact between the front limit wheel 14 and the side of the plate 2 can limit the movement of the plate 2.

[0027] In some specific implementation plans, such as Figure 1 , Figure 3 and Figure 6 As shown, a side plate 15 is provided on the side of the flat plate 2 near the opening of the cabinet bottom plate 1. A baffle 3 is provided on the side plate 15. The baffle 3 is arranged side by side plate 15. The bottom area of ​​the baffle 3 can be used as a pull-out operation space to facilitate the user to pull out the flat plate 2. Two guide grooves 16 are symmetrically opened on the side plate 15. A third threaded rod 17 is inserted inside the guide groove 16. The third threaded rod 17 is fixedly connected to the baffle 3. A second nut 18 is threadedly connected to the third threaded rod 17.

[0028] Loosen the second nut 18 to slide the baffle 3 up and down for adjustment. Once adjusted to the correct position, tighten the nut to fix it in place, thus adjusting the height of the baffle 3. By adjusting the height of the baffle 3, the top of the baffle 3 can better contact and fit with the top of the drawer area at the bottom of the cabinet. The flat drawer structure has simple lines and a strong overall appearance, which helps to improve the overall aesthetics of the cabinet.

[0029] In some specific implementations, to limit the length of the plate 2 that can be pulled out, such as... Figure 1 and Figure 5 As shown, anti-collision plates 10 are fixed on both the side of the cabinet bottom plate 1 behind the rear limit wheel 7 and the side in front of the front limit wheel 14. Elastic pads 9 are fixed on the side of the anti-collision plates 10 closest to the rear limit wheel 7, which can effectively buffer impact force and reduce noise. The anti-collision plates 10 and the rear limit wheel 7 are located on the same horizontal line.

[0030] The rear anti-collision plate 10 limits the rearward displacement of the plate 2, and the front anti-collision plate 10 limits the forward displacement of the plate 2, so as to ensure the smooth movement of the plate 2 inside the bottom of the cabinet.

[0031] In some specific implementation plans, such as Figure 4 and Figure 6 As shown, the mounting plate 11 is located below the rear limit wheel 7, and the connecting rod 13 is designed with a Z-shaped structure, with the lower half of the connecting rod 13 also located below the rear limit wheel 7. By positioning the mounting plate 11 below the rear limit wheel 7 and ensuring that the Z-shaped structure of the connecting rod 13 avoids the rear limit wheel 7, the smooth movement of the rear limit wheel 7 following the plate 2 is guaranteed.

[0032] To enhance the durability of the structure, the surfaces of the plate 2, baffle 3, and side plate 15 are coated with a moisture-proof coating, which improves moisture resistance, especially in damp environments at the bottom of some cabinets. The surfaces of the first threaded rod 6, the first nut 8, the connecting rod 13, the mounting plate 11, and the second threaded rod 12 are all coated with an anti-rust coating to protect the components and ensure a good service life for the product.

[0033] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: When the flat plate 2 is installed in the cabinet bottom plate 1, by loosening the first nut 8, the distance of the rear limit wheel 7 extending out of the side of the flat plate 2 is adjusted so that the rear limit wheel 7 rolls in cooperation with the inner side wall of the cabinet bottom plate 1. Tightening the first nut 8 can lock the first threaded rod 6 in the required position. By adjusting the position of the rear limit wheel 7 through the cooperation of the first threaded rod 6 and the first nut 8, the rear limit wheel 7 can be better adapted to the installation of different sized drawer areas at the bottom of the cabinet. After fixing the mounting plate 11 to the cabinet bottom plate 1, the distance between the connecting rod 13 and the front limit wheel 14 on it and the side of the plate 2 can be adjusted by loosening the third nut 19. This allows the front limit wheel 14 to better adapt to the installation of different sized drawer areas at the bottom of the cabinet. Tightening the third nut 19 to ensure good contact between the front limit wheel 14 and the side of the plate 2 will limit the plate 2.

[0034] When the plate 2 is pulled out, the casters 4 provide support and movement, and the front and rear limit wheels limit the left and right positions of the plate 2 to ensure the smooth movement of the plate.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
