Description

Technical Field

[0001] The invention relates to a concealed positioning and placing structure for a device, in particular to a structure applied to a drawer and capable of concealed positioning and placing of a device. Background Art

[0002] Chinese patent document number CN111086803A disclosed on May 1, 2020 a drawer-type concealed trash can, which includes a trash can, a flat plate, a drawer rail and a connecting device, and the connecting device is either an L-shaped corner code or a wooden strip. It is said that the above structure combines the trash can, the flat plate and the drawer rail into one. Usually, the trash can is hidden in the empty space under the bottom plate of the furniture and is pulled out when needed, eliminating the two major disadvantages of the trash can placed in the room, which is bumpy and unsightly. However, the space in the kitchen varies in size, and the size of the drawer is designed according to the space in the kitchen. At the same time, the size of the trash can varies in size. The drawer size of the above structure is fixed and can only be used to hide trash cans of a single size. Its use is relatively limited. At the same time, when the trash can is placed, it is positioned on the flat plate through the extended edge of the upper side. Not only is the flexibility poor, but also when the trash can is subjected to force, the force will all act on the extended edge of its upper part, resulting in the extension edge being broken and damaged. In severe cases, it will fall, affecting the stability of the trash can. Moreover, after the trash can is placed, it occupies a large space inside the drawer, resulting in very little usable space inside the drawer, which cannot meet the user's use needs. Therefore, it is necessary to make further improvements. Summary of the invention

[0020] 1. Left and right supporting parts are respectively provided at the lower parts of the left and right side panels, and a placing device consisting of a crossbar telescopic assembly and left and right bases is placed between the left and right supporting parts. Positioning parts are respectively provided at both ends of the crossbar telescopic assembly, and are respectively fixed and / or longitudinally slid on the left and right bases.

Therefore, the user can adjust the transverse and longitudinal dimensions of the receiving area when in use, so that devices of different sizes and / or the same size can be positioned and received in receiving areas of different sizes and / or the same size and / or in different positions at will, so as to meet the various receiving requirements of various devices, thereby effectively avoiding the problem of the prior art that the drawer size is fixed and can only receive devices of a single size or the receiving position is fixed, so as to improve the receiving flexibility of the device and provide great convenience for the user to receive and receive the device.

[0022] 3. When the device is placed in the placement area, its side positioning acts on the crossbar telescopic assembly and / or the longitudinal rod, which can effectively position the side of the device to prevent it from tilting during operation. The bottom two sides of the device are respectively positioned on the left and right bases and / or the left and right slide rail assemblies, which can enable the device to exert all its force on the left and right bases and / or the left and right slide rail assemblies when subjected to force, thereby effectively supporting and placing the device, which can not only increase the load-bearing capacity of the device, but also avoid the problem of breakage, damage or falling during operation, so as to ensure the placement stability of the device.

[0023] 4. Both ends of at least two fixed cross bar telescopic assemblies are fixedly connected to the left base and the right base respectively through positioning pieces. At the same time, at least two fixed cross bar telescopic assemblies can realize transverse sliding, thereby realizing the transverse dimension adjustment of the entire supporting device, thereby enabling the supporting device to be suitable for use in drawers with different inner widths, so as to improve the flexibility and application range of the supporting device.

[0024] In general, it has the characteristics of simple and reasonable structure, quick and convenient assembly, low manufacturing cost, good concealment of device placement, good stability, wide range of use, high flexibility, and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
