The state after expansion is locked by the locking component 4. When it is necessary to reset or change the expansion position, the locking component 4 is controlled to stop locking for adjustment.

[0029] In some embodiments, the main board component 2 includes a shelf board 21 , which is fixed to the main frame 1 , and a cavity 22 is opened on the top of the shelf board 21 , and the cavity 22 is used for installing the expansion component 6 .

[0030] The shelf plate 21 is a plate for placing goods on the island shelf, and the cavity 22 is used for the preliminary insertion and installation of the expansion component 6. Figure 3 The left side in the middle is a top view of the main board component 2, and the right side is a bottom view of the expansion component 6.

[0031] In some embodiments, the expansion component 6 includes an expansion plate 61, which is arranged on the upper surface of the shelf plate 21.

A rotating shaft 41 is inserted into the interior of the installation slot 42, and a snap-in block 44 is fixedly connected to the outer wall of the rotating shaft 41. A torsion spring 43 is sleeved on the outer wall of the rotating shaft 41, and both ends of the torsion spring 43 are respectively connected to the rotating shaft 41 and the shelf board 21 inside the installation slot 42, and the snap-in block 44 is snap-in to the snap-in slot 45.

The specific structure is referred to in Figure 4 , you can understand the specific distribution.

[0035] In some embodiments, the connection component 5 includes a connecting block 53 and a connecting plug 54. The connecting block 53 is installed inside one of the two adjacent expansion plates 61 through the installation opening 51, and the connecting plug 54 is installed on the side wall of the other of the two adjacent expansion plates 61. The outer wall of the connecting block 53 is installed with a mounting slide frame 52. The mounting slide frame 52 is mounted on the wall of the expansion plate 61, and the connecting block 53 is plugged into the connecting plug 54.

[0036] The connecting component 5 connects two adjacent expansion plates 61 to achieve synchronization of movement between two or more expansion plates 61. When the connecting plug 53 slides, it drives the installation slide frame 52 to slide on the outer wall of the expansion plate 61 and inserts into the interior of the connecting plug 54, thereby connecting two adjacent expansion plates 61. The opening 51 allows the connecting plug 53 to be displayed externally for control, and the sliding of the frame 52 makes the movement process more stable.

[0037] In some embodiments, the sliding assembly 3 includes a limiting slide groove 31 and a limiting slider 32. There are two limiting slide grooves 31 and they are respectively opened on both sides of the front upper surface of the shelf board 21. There are two limiting sliders 32 and they are respectively installed on both sides of the lower surface of the expansion board 61. The limiting slider 32 is slidably engaged with the limiting slide groove 31.

[0038] When the expansion plate 61 slides, it drives the limiting slider 32 to slide inside the limiting slide groove 31 to limit the straight track and ensure the stability of the sliding process.

[0039] In some embodiments, a handle 7 is installed on the outer wall of the rotating shaft 41 outside the shelf board 21, and the handle 7 facilitates the rotation of the rotating shaft 41.

[0040] In some embodiments, a pull handle 8 is installed on the side wall of the connecting plug block 53 , and the pull handle 8 is convenient for controlling the pulling of the connecting plug block 53 .

[0041] In some embodiments, the space of the mounting slot 42 is larger than the rotation range of the clamping block 44 , so as to ensure smooth rotation of the clamping block 44 .

[0042] In some embodiments, the material of the clamping block 44 is engineering plastic, which has high strength and long service life.

[0043] Working principle: when it is necessary to expand the capacity of the center island shelf, turn the handle 7 to rotate the rotating shaft 41, and apply a force in the opposite direction to the elasticity of the torsion spring 43, driving the clamping block 44 to stop clamping the clamping interface 45. At this time, the expansion plate 61 stops being fixed, and the expansion plate 61 is pulled to drive the plug-in plate 62 to be pulled out from the inside of the cavity 22. When the expansion plate 61 is pulled to meet the required space, release the handle 7, and the elasticity of the torsion spring 43 rotates the rotating shaft 41 to reset and drive the clamping block 44 to clamp the clamping interface 45, fixing the position of the expansion plate 61. When it is necessary to expand the designated area, the plug-in block 53 slides and drives the installation slide frame 52 to slide on the outer wall of the expansion plate 61 and insert it into the inside of the connecting tube 54, thereby connecting two adjacent expansion plates 61. Multiple expansion plates 61 can be pulled out to expand the capacity.
