Technical Field

[0001] The utility model relates to the technical field of cabinets, in particular to a flat basket which can be raised and lowered and extended. Background Art

[0002] Drawers are generally used to store and place items, especially the drawers with telescopic tracks that are widely used now, which bring great convenience to people's lives and work. However, the upper and lower spaces are fixed and cannot be expanded. When there are many things, they may not be able to fit in, especially the placement of dish racks, which makes the usable space even less. The size and height of each layer of drawers are fixed. In the process of storing items, there will be a lot of empty space between the lower drawer and the upper drawer, which cannot be used. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a flat basket that can be raised and lowered and extended, which has the following beneficial effects: when in use, when the extension part moves out of the accommodating part, under the action of the connecting rod assembly, the extension part moves in the horizontal direction and the vertical direction at the same time, so that the extension part can be above the accommodating part, and the space above the accommodating part is expanded to improve the space utilization rate. At the same time, the extension part will not affect the items on the other side of the accommodating part due to the displacement in the vertical direction when moving, thereby meeting people's diverse storage needs.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 2 The utility model is a flat basket that can be lifted and extended, comprising a receiving portion 1; and an extension portion 2, wherein the extension portion 2 is connected to the receiving portion 1 through a connecting rod assembly. When the extension portion 2 moves out of the receiving portion 1, under the action of the connecting rod assembly, the extension portion 2 moves in the horizontal direction and in the vertical direction at the same time;

[0021] In this embodiment, when in use, when the extension part 2 moves out of the accommodating part 1, under the action of the connecting rod assembly, the extension part 2 moves in the horizontal direction and the vertical direction at the same time, so that the extension part 2 can be above the accommodating part 1, and the space above the accommodating part 1 is expanded to improve the space utilization rate. At the same time, since the extension part 2 is displaced in the vertical direction when moving, it will not affect the items on the other side of the accommodating part 1, thereby meeting people's diverse storage needs.

[0022] Furthermore, the utility model is improved in that the connecting rod assembly is symmetrically arranged in two groups, and the two symmetrically arranged groups of connecting rods can ensure the balance of the expansion part 2 during the movement, and can maintain the balance of force on both sides regardless of the extension in the horizontal or vertical direction, thereby reducing the possibility of deflection or shaking, thereby greatly enhancing the stability and safety of the entire structure.

[0023] Furthermore, the utility model is improved in that the connecting rod assembly includes at least two swing rods 3 arranged in parallel. In the present embodiment, there are two swing rods 3, one end of the swing rod 3 is rotatably connected to the accommodating portion 1 via a pin 1 4, and the other end of the swing rod 3 is rotatably connected to the extension portion 2 via a pin 2 5. The two swing rods 3 are of equal length, and the swing rod 3, the pin 1 4, the pin 2 5 and other components form a parallelogram connecting rod structure. When the swing rod 3 rotates, the extension portion 2 can move while keeping the angle unchanged, and the things in the extension portion 2 will not fall off.

[0024] Furthermore, the utility model is improved in that the connecting rod assembly also includes a limit column 6. When the extension part 2 moves out of the maximum position of the accommodating part 1, the limit column 6 contacts one of the swing rods 3. The setting of the limit column 6 allows the user to have clear feedback during use, knowing that the extension part 2 has reached the maximum extension position, avoiding doubts or attempts caused by uncertainty as to whether it can continue to extend, making the operation process more intuitive and reassuring.

[0025] Furthermore, the utility model is improved in that the connecting rod assembly also includes a limiting column 2 7. When the extension portion 2 is completely inside the accommodating portion 1, the limiting column 2 7 contacts one of the swing rods 3. The existence of the limiting column 2 7 provides precise positioning of the closed position for the extension portion 2, ensuring that the extension portion 2 can be completely and accurately returned to the accommodating portion 1, avoiding affecting the overall storage effect due to incomplete closure.

[0026] Furthermore, the utility model is improved in that the limiting column 1 6 , the limiting column 2 7 and the pin shaft 1 4 are all installed on a connecting plate 8 fixed on the inner wall of the accommodating portion 1 , so as to reduce the impact on the inner wall of the accommodating portion 1 .

[0027] Furthermore, the utility model is improved in that the extension part 2 includes a bottom plate 9, a side panel 10 arranged on both sides of the bottom plate 9 and a side panel 2 11 arranged on the other two sides of the bottom plate 9, the bottom end of the side panel 2 11 is bent inward to form an L-shaped portion 12; the pin 2 5 is installed on the L-shaped portion 12; the bending design of the L-shaped portion 12 increases the vertical support part of the side panel 2 11, so that the bottom of the extension part 2 is more stable after unfolding, effectively resisting the load from above, avoiding structural deformation, and enhancing the stability and load-bearing capacity of the entire system.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
