[0034] It is also preferred that when a front-to-rear sliding door structure is adopted, the cabinet opening structure of the present invention also includes a detachable central beam 4; it is worth noting that the left and right side walls of the central beam 4 have the same structure as the inner side walls of the side cabinet opening 1, and from top to bottom also include a first lateral slide groove 12, a second lateral slide groove 13 and a third lateral slide groove 14; the two ends of the central beam 4 are respectively connected to the front cabinet opening 2 and the rear cabinet opening 3.
[0035] Example 1:
[0036] like Figure 6 As shown, when a front-to-back sliding door structure is adopted, the door body includes two front doors 5, two middle doors 6 and two rear doors 7; wherein, a door handle 10 is installed on the glass top of the front door 5; the front door 5 and the middle door 6 slide back and forth along the width direction of the cabinet opening structure.
[0037] Specifically, the left and right sides of the front door 5 are slidably connected to the first lateral guide grooves 12 of the side cabinet opening 1 and the center beam 4, respectively. The front end of the front door 5 corresponds to the first front guide rail 21 of the front cabinet opening 2.
