[0019] The present invention will be further described in detail below with reference to the accompanying drawings. A height-adjustable drawer slide quick connector includes a fixed base 3 fixedly installed at the rear of the drawer 1 and a movable base 4 slidably connected thereto. The movable base 4 is provided with a snap-fit ​​groove 11, and the hook 21 at the rear of the guide rail 2 extends into the snap-fit ​​groove 11 and connects to the movable base 4.

[0020] An adjusting screw 5 is rotatably installed inside the fixed seat 3, and a threaded adjusting groove 41 is provided on the movable seat 4. The threaded part of the adjusting screw 5 engages with the threaded adjusting groove 41. When the adjusting screw 5 is rotated, the thread of the adjusting screw 5 drives the threaded adjusting groove 41, causing the movable seat 4 to move up and down along the fixed seat 3 to adjust the height of the rear of the drawer 1.

[0021] The top of the fixed base 3 is provided with an upper limit plate 31 and a lower limit plate 32. The upper limit plate 31 and the lower limit plate 32 together form a limiting groove 33, and the bolt head 51 of the adjusting screw 5 is clamped and fixed in the limiting groove 33.

[0022] The top of the adjusting screw 5 is provided with a guide shaft 52, and the upper limit plate 31 is provided with a clamping groove 34, which clamps the guide shaft 52.

[0023] The threaded adjustment groove 41 has an inlet groove 42 extending through its body on its side. The fixed base 3 is bent outward and extended to provide a clamping plate 35. The clamping plate 35 passes through the inlet groove 42 and covers the cylindrical surface of the adjustment screw 5.

[0024] The fixed base 3 is bent on both sides to form a number of guide grooves 36. Correspondingly, the inner wall of the movable base 4 is provided with a guide platform 44. The guide platform 44 is slidably fastened in the guide groove 36 and slides up and down along the guide groove 36.

[0025] The movable seat 4 is elastically provided with a positioning post 43, which presses against the end face of the fixed seat 3.

[0026] Working principle: Unlike the traditional method of directly opening the slot at the end of the drawer, the drawer end in this case is equipped with a fixed seat and a movable seat that slides to connect with it. The slot is opened in the movable seat, and the hook at the end of the guide rail extends into the slot to connect and install with the movable seat.

[0027] To adjust the height of the drawer rear, an adjusting screw is installed in the fixed seat, and a threaded adjusting groove is provided on the movable seat. The adjusting screw and the threaded adjusting groove are engaged with each other. By rotating the adjusting screw, the thread on the adjusting screw's cylindrical surface drives the threaded adjusting groove to slide, driving the movable seat to move up and down along the fixed seat. This converts the rotational motion of the adjusting screw into the linear motion of the movable seat, thereby achieving the purpose of adjusting the height of the drawer rear. The height of the drawer rear can be quickly corrected without disassembly. The adjustment operation is simple and quick, making it convenient for users to maintain the drawer. This ensures that the drawer and the guide rails are always in optimal working condition, and even if they become loose later, they can be quickly adjusted to ensure the long-term stable operation of the drawer.

[0028] The structure of the adjusting screw and threaded adjusting groove is flexible and compact, without taking up extra space between the drawer and the guide rail. It is suitable for use in various drawer guide rail systems, and has strong versatility and practicality.

[0029] The system includes an upper limit plate and a lower limit plate at the top of the fixed base. These two limit plates together form a limiting groove, within which the head of the adjusting screw is clamped, locking the screw's axial movement. The adjusting screw can only rotate, preventing axial movement and ensuring the movable base can slide axially along the fixed base, guaranteeing stable and reliable adjustment. A guide shaft is located at the head of the adjusting screw. Additionally, a clamping groove is formed within the upper limit plate, engaging with the outer cylindrical surface of the guide shaft. This further restricts the axial movement of the adjusting screw, enhancing its reliability and preventing axial displacement.

[0030] A clamping plate is also provided inside the fixed seat. The clamping plate extends through the guide groove of the movable seat into the threaded adjustment groove and covers and presses against the cylindrical surface of the adjusting screw, locking the radial movement of the adjusting screw. This effectively prevents the adjusting screw from shaking during the adjustment process and ensures that the adjusting screw can only rotate around its own axis, thus ensuring its long-term stability.

[0031] Multiple limit structures are set up to restrict and lock the adjusting screw, thereby ensuring the adjustment accuracy of the adjusting screw, improving its stability and reliability, avoiding adjustment failure caused by the adjusting screw itself, and improving the user experience and service life of the product.

[0032] To further ensure the sliding path of the movable seat, several guide grooves are formed by bending on both sides of the fixed seat. A guide platform is provided on the inner wall of the movable seat to correspond to the guide grooves. The guide platform is slidably fastened in the guide groove and slides up and down along the guide groove to limit the axial sliding path of the movable seat.

[0033] A positioning post is also flexibly set on the movable seat. The positioning post presses against the end face of the fixed seat. The positioning post provides a certain friction between the movable seat and the fixed seat. After the height is adjusted, the friction can effectively prevent the movable seat from moving due to external force, ensure the stable and reliable adjustment position of the movable seat, and enhance the connection strength between the two. Therefore, it can be widely promoted.

[0034] 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.
