[0028] like Figures 1 to 6As shown, a retractable three-section drawer slide that is easy to assemble and disassemble includes: a fixed frame 1, with a connecting strip 101 and a sliding strip 102 sequentially arranged on the inner side of the fixed frame 1, and the connecting strip 101 and the sliding strip 102 sliding relative to the fixed frame 1; a connecting mechanism, disposed inside the sliding strip 102, used to limit the drawer's position, the connecting mechanism including a connector 2 and a sliding member 3, the connector 2 being disposed through the sliding strip 102 and connected to the drawer, used to connect the drawer and the sliding strip 102, the sliding member 3 being disposed inside the sliding strip 102, used to limit the connector 2 on the sliding strip 102, and the connector 2 cooperating with the sliding member 3 to fix the drawer's position, specifically, when using During use, the drawer is connected to the sliding strip 102 via connector 2 to ensure stability during the connection process. Then, the position of connector 2 is limited by the cooperation of sliding piece 3 and sliding strip 102 to prevent connector 2 from slipping off from sliding strip 102 during use. Connector 101 and sliding strip 102 can drive the drawer to move relative to the fixed frame 1 during use. A buffer damper is also provided between the fixed frame 1 and sliding strip 102 to achieve a quiet, smooth, and gentle opening and closing effect, avoiding noise caused by drawer impact. The fixed frame 1 is connected to the cabinet panel during use, thereby providing support for the drawer during use.

[0029] like Figures 1 to 6 As shown, the top of the sliding bar 102 is also provided with a hook 103, and the hook 103 is L-shaped. The sliding bar 102 has a sliding groove 105 inside, and a limiting hole 104 and a connecting hole 106 are respectively provided on the outer side of the sliding bar 102. The limiting hole 104 and the connecting hole 106 are connected to the sliding groove 105, and the opening direction of the limiting hole 104 is perpendicular to the opening direction of the connecting hole 106. Specifically, during use, the drawer is limited by the cooperation of the hook 103 and the connecting piece 2 to ensure the stability of the drawer's position relative to the sliding bar 102 during use. The hook 103 and the sliding bar 102 can be connected by welding or bolts. Ball bearings are provided between the fixing frame 1, the connecting bar 101 and the sliding bar 102 to reduce the friction between the fixing frame 1, the connecting bar 101 and the sliding bar 102. The sliding groove 105 can guide the sliding piece 3 during use to ensure the stability of the moving direction of the sliding piece 3 during use.

[0030] like Figures 1 to 6As shown, the connector 2 includes a connecting block 201, which slides inside the limiting hole 104. A connecting rod 203 is provided inside the connecting block 201. Specifically, the connecting rod 203 connects the connecting block 201 to the drawer during use, ensuring a stable connection between the connecting block 201 and the drawer. The connecting rod 203 and the drawer can be connected via a slot or thread. The connecting block 201 can be T-shaped or dovetail-shaped. The cooperation between the connecting block 201 and the limiting hole 104 buffers vibrations at the connection point during use, preventing damage to the connecting block 201 during prolonged use. The drawer has a buffer groove on its side relative to the hook 103, allowing the hook 103 to slide inside the buffer groove. During use, the hook 103 limits the drawer's position and guides its movement, ensuring the drawer can stably move the connecting block 201 relative to the hook 103.

[0031] like Figures 1 to 6 As shown, the outer wall of the connecting block 201 is also provided with a groove 202. Specifically, the groove 202 can be arc-shaped or V-shaped.

[0032] like Figures 1 to 6 As shown, the sliding component 3 includes a sliding block 301, which slides inside the sliding groove 105. A slot 304 is provided on the side of the sliding block 301 opposite to the connecting block 201. At least one guide rod 303 is provided on the outer side of the sliding block 301. The axis of the guide rod 303 is parallel to the length direction of the sliding strip 102, and the guide rod 303 slides inside the sliding strip 102. A pressing rod 305 is also provided on the side of the sliding block 301 opposite to the connecting hole 106, and the pressing rod 305 slides inside the connecting hole 106. Specifically, during drawer installation, the connecting block 201 is first inserted into the limiting hole 104, and then... The sliding block 301 slides along the sliding groove 105. During the sliding process, the sliding block 301 controls the slot 304 to insert into the groove 202, thereby limiting the position of the connecting block 201 and the drawer during use. The pressing rod 305 is connected to the sliding block 301 by threads, thereby limiting the position of the sliding block 301 during use and preventing the sliding block 301 from moving relative to the connecting block 201 during use. The guide rod 303 can guide the sliding block 301 during use, further ensuring that the sliding block 301 can slide stably inside the sliding groove 105.

[0033] like Figures 1 to 6As shown, the inner wall of the sliding groove 105 is also provided with a storage groove 107, which corresponds one-to-one with the guide rod 303. The storage groove 107 is provided with a spring 302, and the spring 302 is sleeved on the outside of the guide rod 303. Specifically, the spring 302 can provide a pushing force to the sliding block 301 during use, ensuring that the slot 304 can stably fit with the connecting block 201 during use, while providing the power to reset the sliding block 301 and the connecting block 201 when they move. The storage groove 107 can store the compressed spring 302 to avoid interference between the spring 302 and the sliding block 301 during the compression process.
