The base 30 fixes the upper beam 3 to the mounting bracket 1 through the first hook portion 301a and the second hook portion 303a correspondingly hooking with the first hook 101 and the second hook 121, respectively, so that the upper beam 3 is fixed to the mounting bracket 1, and the disassembly and assembly are more convenient. The mounting bracket 1 can be fixed to the wall in advance by fasteners such as bolts and does not need to be disassembled and replaced under normal circumstances; moreover, by snapping the cover 32 on the base 30 to enclose the storage cavity 3a of the upper beam 3, the storage cavity 3a can be effectively shielded to prevent dust from falling on the movable components assembled in the storage cavity 3a, thereby ensuring the normal operation of each movable component and avoiding wear and additional noise caused by dust.

[0037] In an optional embodiment of the present invention, Figure 1-Figure 4 As shown, the first hook 101 is a hook formed by bending from a side edge of the top plate 10 away from the vertical plate 12 and extending a predetermined distance toward the vertical plate 12 to form a semi-enclosed shape and a first opening 101a is formed toward the side of the vertical plate 12.

In addition, the provision of the elastic arm 123 also facilitates the disassembly and assembly of the upper beam 3. The specific assembly operation process of the upper beam 3 is as follows: the second hook portion 303a on the bottom plate 303 is hooked on the second hook 121 at the bottom end of the elastic arm 123, and the upper beam 3 is pushed to force the elastic arm 123 to elastically deform and retreat, so that the first hook portion 301a on the panel passes over the first hook 101, and then the upper beam 3 is slightly rotated and lifted with the hooking position of the second hook portion 303a and the second hook 121 as the center so that the first hook portion 301a is aligned with the first hook 101. At this time, the pushing force on the upper beam 3 is reduced or cancelled, and the elastic arm 123 can be elastically reset to push the upper beam 3 back, so that the first hook portion 301a and the first hook 101 are also correspondingly hooked and matched, thereby achieving assembly. The disassembly operation process of the upper beam 3 is as follows: first push the upper beam 3 to squeeze the elastic arm 123, so that the first hook portion 301a can be disengaged from the first hook 101, and then slightly rotate and move the upper beam 3 downward to make the first hook 101 and the first hook portion 301a staggered up and down, and then reduce or cancel the pushing force on the upper beam 3, the elastic arm 123 can elastically reset and push the upper beam 3 back, and the first hook portion 301a also passes over the first hook 101 again, and the upper beam 3 can be removed from the mounting bracket 1.
