The extension 8.3 and the moving slide rail 2 always maintain a gap.

[0074] See Figure 14 , Figure 15 A drawer 8 is connected to the movable slide rail 2, and the fixed slide rail 1 is fixed to the inside of the cabinet body 13. The drawer slide rail assembly on one or both sides between the drawer 8 and the cabinet body 13 is equipped with a left-right adjustment mechanism. This mechanism reduces production costs. When the distance between the drawer 8 and the left or right side of the cabinet body 13 is large, it can be adjusted using the left-right adjustment mechanism.

[0075] Referring to Figures 10-13 , the fixed slide rail 1 has a gap with the movable slide rail 2, the movable slide rail 2 and the movable block 5 are respectively provided with a plug-in part connected with the drawer 8, the drawer 8 comprises a side plate 8.1 and a bottom plate 8.2 supported on the movable slide rail 2, the side plate 8.1 is provided with an extension 8.3 protruding from the bottom plate 8.2 and located on the gap, and the extension 8.3 is provided with an adjusting gap 9 matched with the lateral sliding of the movable block 5; the movable block 5 slides laterally and drives the extension 8.3 to move left and right on the gap, thereby adjusting the gap between the drawer 8 and the inner side of the cabinet 13 (adjusting the left and right positions of the drawer 8 and the cabinet 13). In this embodiment, when the drawer 8 is assembled with the slide rail assembly, the extension 8.3 of the side plate 8.1 is located on the gap.

[0076] Referring to Figure 16 , Figure 17 , the extension 8.3 is provided with a first insertion hole 8.4 at the bottom of the extension 8.3, and the second connecting part 10 is a side hook inserted into the first insertion hole 8.4.

[0077] In this embodiment, the side hook of the movable block 5 is close to the front end of the movable slide rail 2, so that the front end of the drawer 2 is positioned on the movable slide rail 2 by inserting the side hook into the first insertion hole 8.4.

[0078] Referring to Figure 16 , Figure 17 , the plug-in part further comprises a second insertion hole 8.5 provided on the inner side of the extension 8.3, and the movable slide rail 2 is provided with a bolt 11 inserted into the second insertion hole 8.5.

[0080] The cooperation of the first insertion hole 8.4 and the side hook, the cooperation of the second insertion hole 8.5 and the bolt 11, and the cooperation of the third insertion hole 8.7 and the rear hook enable the drawer 8 to be relatively fixed on the movable slide rail 2, and the plug-in part and the insertion hole can be gap matched.

[0081] In this embodiment, the rear hook is close to the rear end of the movable slide rail 2, so that the rear end of the drawer 2 is positioned on the movable slide rail 2 by inserting the side hook into the third insertion hole 8.7.

[0082] In this embodiment, the movable slide rail 2 is provided with a through slot penetrating through the inner and outer sides of the movable slide rail 2, one end of the bolt 11 is provided with a push rod 17, and the push rod 17 is partially inserted into the through slot. When the front and rear ends of the drawer 2 are positioned on the movable slide rail 2, the bolt 11 is pushed into the second insertion hole 8.5 by the push rod 17, which prevents the drawer 8 from being easily pulled out of the movable slide rail 2 after positioning, and enables the drawer 8 to be relatively fixed on the movable slide rail 2.

[0083] A rotating member 14 is arranged between the bottom plate 8.2 and the top of the movable slide rail 2. The top of the movable slide rail 2 is provided with an open slot 2.1. The movable slide rail 2 is further provided with a notch 2.2 which is in communication with the open slot 2.1. The rotating member 14 comprises a rotating wheel 14.1 which is arranged on the notch 2.2 and a cam 14.2 which is arranged on the open slot 2.1. The cam 14.2 partially protrudes from the rotating wheel 14.1. During the rotation of the cam 14.2, the cam 14.2 is hidden in or protrudes from the open slot 2.1. Thus, the inclination 15 (the distance between the top and the bottom) between the bottom plate 8.2 and the movable slide rail 2 is adjusted.

[0084] In the embodiment, the rotating member 14 further comprises a handle 14.3 which is connected with the cam 14.2. The other side of the movable slide rail 2 is provided with a recess which corresponds to the handle 14.3. The handle 14.3 is partially limitedly arranged on the recess. The handle 14.3 is shaken to rotate the rotating member 14. The rotating wheel 14.1 and the notch 2.2 are provided with meshing teeth. The rotating member 14 is adjusted in stages through the meshing teeth. The notch 2.2 and the meshing teeth form a limiting rotating part 21.

[0085] Alternatively, the limiting rotating part 21 can be a threaded slot. It can be understood that the rotating wheel 14.1 and the notch 2.2 are threadedly connected.

[0086] When the drawer 8 is in a heavy state, the front side of the drawer 8 will be inclined downward on the movable slide rail. Therefore, the rotating member 14 which adjusts the inclination 15 between the bottom plate 8.2 of the drawer 8 and the movable slide rail 2 is arranged to lift the bottom plate 8.2 of the drawer 8. The drawer 8 is inclined upward on the movable slide rail 2. Thus, the front side of the drawer 8 will not be inclined downward on the movable slide rail 2 when the drawer 8 is in a heavy state.

[0087] Second Embodiment

[0088] Referring to Figures 24-33 The drawer slide rail assembly is different from the first embodiment in that the movable block 5 is provided with a side column which is inserted into the first insertion hole 8.4. The movable block 5 is provided with a movable member 16 which is arranged on the side column in an up-and-down lifting manner and is in contact with the bottom surface of the extension part 8.3. The movable member 16 adjusts the inclination 15 (the distance between the top and the bottom) between the bottom plate 8.2 and the movable slide rail 2 during the lifting process.

[0089] In the embodiment, the movable member 16 is threadedly connected and is lifted on the side column in an up-and-down manner. When the drawer 8 is in a heavy state, the front side of the drawer 8 will be inclined downward on the movable slide rail. Therefore, the movable member 16 which adjusts the inclination 15 between the bottom plate 8.2 of the drawer 8 and the movable slide rail 2 is arranged. The movable member 16 drives the extension part 8.3 to be lifted upward during the lifting process. Thus, the bottom plate 8.2 of the drawer 8 is lifted. The drawer 8 is inclined upward on the movable slide rail 2. Thus, the front side of the drawer 8 will not be inclined downward on the movable slide rail 2 when the drawer 8 is in a heavy state.

[0090] Other parts not mentioned are the same as the first embodiment, and will not be described here.

[0091] Third embodiment
