[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] According to the attached Figures 1 to 4 As shown, the utility model has an adaptive slide rail installation mechanism, comprising a fixed rail 1, a middle rail 2, and a movable rail 3 which are slidably connected in sequence, wherein the fixed rail 1 is installed on the cabinet, and the movable rail 3 is installed on the drawer. The movable rail 3 is provided with a tail end installation device 4 with an adaptive installation function. The tail end installation device 4 comprises a fixed frame 41, a movable frame 42, and an elastic member 43. The fixed frame 41 is installed at the end of the movable rail 3, and the movable frame 42 is installed on the fixed frame 41, and the movable frame 42 is provided with a tail hook 5 which is adapted to be buckled with the drawer, and the two elastic ends of the elastic member 43 are respectively clamped on the fixed frame 41 and the movable frame 42, so that the movable frame 42 has the potential energy to always keep pushing forward on the fixed frame 41 under the elastic action of the elastic member 43.

[0024] In this way, through the structural coordination of the movable frame 42, the fixed frame 41, and the elastic member 43 of the tail end mounting device 4, after the movable frame 42 is assembled on the drawer, the elastic action of the elastic member 43 allows the movable frame 42 to always maintain the forward pushing potential energy relative to the fixed frame 41, so that the tail hook 5 is adaptively and firmly fastened to the drawer, so as to adjust the assembly gap between the drawer and the slide rail. The adaptive assembly has high stability, avoids large floating when pushing and pulling the drawer after assembly due to excessive gap, reduces noise generation, is reliable and practical, and has high applicability.

[0025] Reference Figures 1 to 4 As shown, in further detail, the fixed frame 41 is provided with a guide groove 44 for adapting the movable frame 42 to slide forward and backward, and the tail hook 5 is arranged on the front side of the upper end surface of the movable frame 42, and the tail hook 5 is connected with or separated from the fixed frame 41 as the movable frame 42 contacts with the fixed frame 41 when the elastic member 43 is compressed or the elastic member 43 is elastically reset.

[0026] Under the action of the guide groove 44 , the movable frame 42 is directional-slid on the fixed frame 41 , thereby reducing the swing amount of the connection between them and improving the connection stability.

[0027] Meanwhile, a limiting pin 45 for limiting the forward and backward movement of the movable frame 42 is disposed on the upper end surface of the movable frame 42 , and a limiting groove 46 for matching and slidably connecting with the limiting pin 45 is formed on the fixed frame 41 .

[0028] The structural cooperation between the limiting nail 45 and the limiting groove 46 prevents the movable frame 42 from being separated from the fixed frame 41, and effectively limits the movement of the movable frame 42, thereby limiting the adjustment range of the gap between the drawer and the slide rail.

[0029] Reference Figures 1 to 3As shown, in further detail, the left and right sides of the fixing frame 41 are respectively connected with connecting plates 47, and the connecting plates 47 are provided with buckling flanges 48 that can be detachably mounted on the ends of the movable rails 3. The structure is simple, easy to assemble, and the structural connectivity is enhanced.

[0030] In addition, one side of the fixed frame 41 is provided with an installation groove 49 for adapting the installation of the elastic member 43, the front end of the installation groove 49 is provided with a front buckle 410 for buckling with an elastic end of the elastic member 43, and the movable frame 42 is provided with a rear buckle 411 for buckling with the other elastic end of the elastic member 43.

[0031] The elastic member 43 may be a tension spring or a compression spring.
