When installing the backplane structure, first install the bottom end of the backplane frame 2 on the backplane 1, and then rotate the backplane frame 2 so that its top is close to the backplane 1. After the backplane frame 2 contacts the fixing member 3, continue to press the backplane frame 2 to make it cooperate with the fixing member 3. In this way, the top of the backplane frame 2 is installed on the backplane 1, and the installation of the entire backplane structure is completed. When disassembling the backplane structure, first disengage the top of the backplane frame 2 from the fixing member 3, and then rotate the backplane frame 2 so that its top moves in the direction away from the backplane 1, and then remove the bottom end of the backplane frame 2 from the backplane 1.

[0038] The back panel frame 2 of the present invention is provided with a slider cavity at the top, in which a slider 4 and a latch 5 are arranged. The slider 4 can slide in the slider cavity along a direction perpendicular to the back panel 1, and the latch 5 can move in the slider cavity along a vertical direction as the slider 4 slides (the horizontal direction and the vertical direction in the present invention are respectively Figure 2), the latch 5 slides up and down to engage with or disengage from the fixing member 3. The present invention has a through hole 6 with a rectangular longitudinal section running through both sides of the latch 5, and the projection of the through hole 6 on the back plate 1 is rectangular. The lower surface of the slider 4 is a first inclined surface 7, and the first inclined surface 7 is inclined upward at one end close to the back plate 1. The slider 4 passes through the through hole 6, and the first inclined surface 7 fits with the lower surface of the through hole 6. The slider 4 is subjected to a horizontal force and slides in the through hole 6 toward the back plate 1 to press the latch 5 to slide downward so that the top of the latch 5 is disengaged from the fixing member 3. The bottom of the latch 5 is provided with an elastic member 8, which is used to push the latch 5 upward and push the slider 4 away from the back plate 1 when the horizontal force on the slider 4 disappears.
