The two ends of the mounting seat 1 in the length direction are respectively provided with a flat mounting cavity 2, and the thickness of the mounting cavity is adapted to that of the mounting seat, so that the product is simple and attractive in appearance. All be equipped with lifting unit 3 in two installation cavity 2, each lifting unit 3 all is connected with lift actuating mechanism 4.

A shelf 5 connected with the two lifting components 3 is arranged at the lower side of the mounting seat 1; when the device is not used, the article placing frame 5 is tightly attached to the bottom of the mounting seat 1 under the matching of the lifting component 3 and the lifting driving mechanism 4, and when the device is used, the article placing frame 5 descends downwards and is suspended below the mounting seat 1 under the matching of the lifting component 3 and the lifting driving mechanism 4. The shelf is preferably horizontal according to actual requirements when in the final suspension state, but according to specific use requirements. The object placing table can also form a certain included angle with the horizontal plane, such as 5-10 degrees.

The shelf 5 is composed of a frame body 5a, a shelf 5b arranged in the frame body 5a and a handle 5c arranged at the front side of the frame body 5 a; the lifting assembly 3 is connected to the frame 5 a.

In this embodiment, the lifting assembly 3 includes a first linkage rod 3a and a second linkage rod 3b hinged to each other in an X-shape. When the riveting device is used for machining, the first linkage rod and the second linkage rod are connected in a riveting mode, and after riveting is carried out, the riveting point serves as a rotating shaft, so that the two rods rotate along the riveting point. One end of each of the first linkage rod 3a and the second linkage rod 3b, which is vertically opposite to each other, is hinged with the corresponding installation cavity 2 and the corresponding article shelf 5, and the other end of each of the first linkage rod 3a and the second linkage rod 3b is movably connected with the corresponding article shelf 5 and the corresponding installation cavity 2 through a first guide structure 6 and a second guide structure 7 which are matched with each other; the lifting driving mechanism 4 is hinged with the first linkage rod 3a or the second linkage rod 3 b.

Further preferably, the first guiding structure 6 is composed of a roller 6a arranged at the lower end of the first linkage rod 3a and a guiding groove 6b arranged at the end of the article carrier 5 and matched with the roller 6 a.

When the rollers 6a are located at both ends of the guide groove 6b, the rack 5 is closely attached to the bottom of the mounting base 1 or suspended below the mounting base 1.

Further preferably, the second guide structure 7 is composed of a grooved pulley 7a arranged at the upper end of the second linkage rod 3b and a long guide hole 7b formed on the side wall of the installation cavity 2 and matched with the grooved pulley 7 a; when the grooved pulleys 7a are positioned at both ends of the long guide holes 7b, the article carrier 5 is closely attached to the bottom of the mounting seat 1 or suspended below the mounting seat 1.

In this embodiment, the lifting driving mechanism 4 is composed of a gas spring 4a hinged in the installation cavity 2 and a connecting block 4b fixedly arranged on the first linkage rod 3a or the second linkage rod 3b and hinged with the gas spring 4 a.

Theoretically, when the rack is in a straight line, the force required by the rack during resetting is the minimum, but in actual use, the smooth degree of the components is considered, and some friction resistance exists, so that the angle of the included angle alpha can be adaptively deviated according to the friction resistance of the components, and the use is not obviously influenced. These too will be readily apparent to the skilled person.

Further preferably, a synchronizing rod 8 is connected between the upper parts of the first linkage rod 3a and the second linkage rod 3b on both sides of the mounting seat 1. When the commodity shelf is pulled, the synchronous rods can enable the lifting components on the two sides to act synchronously, and therefore the stability of the whole commodity shelf is improved.

In order to reduce the interference of the synchronous rod to the space above the commodity shelf, improve the utilization rate of the commodity shelf and simultaneously make the appearance attractive, the synchronous rod 8 is connected to the near end part of the upper end of the first linkage rod 3a or the second linkage rod 3b positioned on the rear side of the mounting seat 1; the side wall of the installation cavity 2 is provided with a abdicating notch 2a which is matched with the synchronizing rod 8.

When the rack is used, the rack is firstly arranged on the top of the water tank or the bottom of the hanging cabinet on the side or the wall or the bracket at the bottom of the hanging cabinet. Or the wall or the bracket can be arranged at the bottom of the wall cabinet or the bottom of the wall cabinet above the side of the cooking range according to the requirement.

When some dishes need to be temporarily placed when draining or cooking is needed, the handle on the storage rack is pulled to vertically descend in place, and then the food storage rack can be used. After the use, the handle is slightly pushed upwards, and the storage state can be recovered under the action of the air spring. The use is very convenient.

The above embodiment is the preferred embodiment of the present invention, which is only used to facilitate the explanation of the present invention, it is not right to the present invention, which makes the restriction on any form, and any person who knows commonly in the technical field can use the present invention to make the equivalent embodiment of local change or modification without departing from the technical features of the present invention.
