[0022] The present invention will be further described in detail below with reference to the accompanying drawings. A height-adjustable drawer slide tail seat includes a mounting base 3 fixed to the tail of the guide rail 1. The two sides of the mounting base 3 extend outward to form movable grooves 31. A tail hook 4 is slidably embedded in the movable grooves 31. An adjusting screw 5 is provided through the mounting base 3, and the adjusting screw 5 passes through the tail hook 4 and abuts against the end face of the guide rail 1.

[0023] The tail hook 4 includes an elastic plate 41 and an adjusting plate 42, which are connected as one unit by a connecting plate 43. The elastic plate 41 extends into and is fastened in the latching groove 21 at the rear of the drawer 2. The front end of the adjusting plate 42 is bent downward. Correspondingly, a clearance groove 11 is provided on the end face of the guide rail 1. The adjusting plate 42 is built into the clearance groove 11, clamping the rear of the drawer 2 between the adjusting plate 42 and the elastic plate 41. Rotating the adjusting screw 5 causes the tail hook 4 to move up and down, adjusting the height of the rear of the drawer 2 relative to the drawer 2.

[0024] The elastic plate 41 has a threaded hole 411, and the adjusting screw 5 has a threaded post 51 on its cylindrical surface, which is screwed into the threaded hole 411.

[0025] The adjusting plate 42 has a through hole 421 at the position corresponding to the threaded hole 411. The adjusting screw 5 passes through the mounting base 3, the threaded hole 411 and the through hole 421 in sequence, and presses against the upper end face of the guide rail 1.

[0026] The inner wall of the mounting base 3 is bent inward from its body to form a limiting plate 33. The limiting plate 33 is pressed and clamped onto the threaded post 51 to limit the movement stroke of the adjusting screw 5.

[0027] The bottom of the movable groove 31 is provided with baffles 32 on both sides, and the tail hook 4 is located between the two baffles 32.

[0028] The elastic plate 41 has a recessed and hollowed-out deformation groove 412 at one end.

[0029] The elastic plate 41, connecting plate 43 and adjusting plate 42 are integrally bent from metal sheets.

[0030] Working principle: A mounting base is provided at the end of the guide rail. Movable grooves are formed by the outward extension of both sides of the mounting base. The tail hook is slidably embedded in these grooves and locked inside the baffle of the mounting base. An adjusting screw runs through the mounting base, passes through the tail hook, and presses against the end face of the guide rail, adjusting the height of the drawer's rear end relative to the drawer.

[0031] It should be noted that the tail hook includes a flexible plate and an adjusting plate, which are connected as one unit using a connecting plate. The flexible plate extends into and snaps into the groove at the rear of the drawer, allowing for quick installation of the drawer and guide rails. A deformation groove is recessed and cut out at the end of the flexible plate, providing sufficient deformation space for the plate during the snap-fit ​​process.

[0032] The adjusting plate has its front end bent downwards and is integrated into a clearance groove on the end face of the guide rail. After the guide rail and drawer are connected and fastened, the clearance groove clamps the drawer rear between the adjusting plate and the spring plate. The adjusting screw passes through the threaded hole of the spring plate and the through hole of the adjusting plate, finally pressing against the upper end face of the guide rail. When the height of the drawer rear needs to be adjusted, rotating the adjusting screw, through its connection with the threaded hole, converts the rotational movement of the adjusting screw into the up-and-down movement of the tail hook. The tail hook moves synchronously with the sliding of the adjusting screw, using the adjusting plate to lift or lower the drawer rear, thereby changing the height of the drawer rear relative to the guide rail. This allows for precise and stable adjustment, enabling users to directly adjust the height during use, avoiding the inconvenience of overall disassembly and installation, reducing later maintenance and repair costs. This ensures that the drawer guide rail maintains good adaptability even after long-term use through convenient adjustment, extending its service life.

[0033] Furthermore, the combination of threaded posts and threaded rods allows for fine-tuning of the height, ensuring that the drawer slides can be stably installed in different environments. Users can precisely adjust the drawer height according to their actual needs, ensuring smooth opening and closing of the drawer and improving the product's adaptability and user experience.

[0034] Furthermore, the inner wall of the mounting base is also equipped with a limiting plate. The limiting plate is locked on top of the threaded column, which restricts the movement stroke of the adjusting screw and avoids the rod from coming off due to excessive adjustment and rotation, so that this adjusting structure can work stably and efficiently for a long time.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
