[0036] Referring to FIG. 1 to FIG. 5, a quick detachable slide rail includes a fixed rail 100 and a movable rail 300. The fixed rail 100 is provided with a mounting hole 111. The fixed rail 100 includes a back plate 110, a bottom plate 120, and a side plate 130. The back plate 110 is provided with the mounting hole 111. The side plate 130 is provided with a guide rail part 131. A lower bead holder 200 is slidably mounted on the guide rail part 131. The movable rail 300 is arranged on the lower bead holder 200. An expanded glue particle 400 is fixed on the mounting hole 111. The expanded glue particle 400 includes an expansion part 410 and a spacing gap 420. The expansion part 410 is at least two. The spacing gap 420 is formed between the expansion parts 410. A rotating rod 500 is provided with a push piece 600. The rotating rod 500 is rotated by pushing the push piece 600. The rotating rod 500 is inserted into the expanded glue particle 400 through the mounting hole 111. The rotating rod 500 is provided with a convex part 510. When the rotating rod 500 is inserted into the expanded glue particle 400, the convex part 510 is located in the expanded glue particle 400. The push piece 600 has a first working position and a second working position. When the push piece 600 is pushed to the first working position, the convex part 510 releases the expansion of the expansion part 410. When the push piece 600 is pushed to the second working position, the convex part 510 is rotated to the position of the expansion part 410 and outwardly supports the expansion part 410, so that the expansion part 410 is expanded.

[0037] In the drawing 4, the position of the push piece 600 is the first working position.

[0038] In the drawing 5, the position of the push piece 600 is the second working position.

[0039] Referring to FIG. 3 to FIG. 5, when installing the slide rail, first, the expanded glue particle 400 is inserted into the mounting hole 111 on the cabinet. Then, the push piece 600 is pushed from the first working position to the second working position, so that the convex part 510 is rotated to the expansion part 410. The convex part 510 outwardly supports the expansion part 410, so that the expansion part 410 is expanded and tightly fixed in the mounting hole 111, thereby achieving the fixed installation of the slide rail.

[0040] Conversely, when disassembling the slide rail, the push piece 600 is pushed from the second working position to the first working position, so that the convex part 510 is rotated away from the expansion part 410 or aligned with the spacing gap 420. The outward support of the convex part 510 on the expansion part 410 is released, so that the expansion part 410 is no longer expanded and tightly fixed. The expanded glue particle 400 can be pulled out of the mounting hole 111 on the cabinet, thereby achieving the disassembly of the slide rail.

[0041] Through the above structure, the quick installation of the slide rail is achieved, the installation time is saved, and no fastening tool is needed, which brings convenience to the installation and reduces the installation difficulty.

[0042] Referring to Fig. 6, to facilitate the fixing and installation of the expanded glue particles 400, a notch 112 is arranged at the edge of the installation hole 111, and a protrusion 430 is arranged on the expanded glue particle 400, which is clamped into the notch 112 to fix the expanded glue particle 400 in the installation hole 111.

[0043] Meanwhile, the expanded glue particle 400 is kept fixed to avoid rotating with the rotating rod 500 during the rotation of the rotating rod 500, which affects the expansion of the convex portion 510.

[0044] Referring to Fig. 6, to further strengthen the stability of the expanded glue particle 400 after being fixed, two notches 112 are symmetrically arranged.

[0045] Referring to Fig. 5, a limiting baffle 610 is arranged on the push piece 600, which is in contact with the edge of the back plate 110 when the push piece 600 is pushed from the first working position to the second working position.

[0046] The limiting baffle 610 is arranged on the push piece 600, which is in contact with the edge of the fixed rail 100 when the push piece 600 is pushed from the first working position to the second working position, so that the push piece 600 is fixed at the second working position, and the expanded portion 410 is kept in the expanded state under the expansion of the convex portion 510, thereby ensuring the stability after installation.
