[0002] As an important core component of the drawer opening and closing movement in modern furniture, the guide rail is widely used in cabinets, wardrobes and other furniture products due to its simple structure, convenient installation, smooth and stable sliding process and precise positioning. The installation of traditional guide rails and drawers usually sets a buckle groove at the end of the guide rail, and a hook is set at the end of the drawer. The hook is used to dock and fix with the buckle groove, so that the drawer and the guide rail can be quickly connected and installed, which is convenient to operate and ensures the normal push and pull and smooth sliding of the drawer.

[0003] However, the docking of the hook and the buckle slot requires a high degree of installation accuracy between the two. The hook and the buckle slot must be precisely aligned to accurately dock and install. If the buckle slot is not set correctly or there is a slight deviation, or the docking of the tail hook and the buckle slot is not completely aligned, it will cause the drawer to get stuck or be unbalanced in the front and back during the sliding process, and even the two cannot be docked and installed. During the long-term push-pull use of the drawer, the installation of the hook and the buckle slot is prone to loosening or deformation, resulting in the connection between the two no longer being tight and firm. At this time, the drawer is prone to loosening or even unable to open and close normally, reducing its safety and affecting the service life of the drawer. Summary of the invention

[0018] The present invention is further described in detail below with reference to the accompanying drawings. A height-adjustable drawer rail quick connector includes a fixed seat 3 fixedly mounted at the rear of a drawer 1 and a movable seat 4 slidably connected thereto, wherein a buckle slot 11 is provided in the movable seat 4, and a hook 21 at the rear of the guide rail 2 extends into the buckle slot 11 and is connected to the movable seat 4; An adjusting screw 5 is rotatably installed in the fixed seat 3, and a threaded adjusting groove 41 is provided on the movable seat 4. The threaded portion of the adjusting screw 5 is engaged 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, so that the movable seat 4 moves up and down along the fixed seat 3 to adjust the height of the tail of the drawer 1.

[0019] An upper limit plate 31 and a lower limit plate 32 are disposed on the top of the fixing seat 3 . The upper limit plate 31 and the lower limit plate 32 are combined to form a limit groove 33 . The bolt head 51 of the adjusting screw 5 is clamped and fixed in the limit groove 33 .

[0020] A guide shaft 52 is disposed on the top of the adjusting screw 5 , and a clamping groove 34 is formed on the upper limit plate 31 . The clamping groove 34 is clamped outside the guide shaft 52 .

[0021] The side of the threaded adjustment groove 41 is provided with an introduction groove 42 penetrating through the body thereof. The fixing seat 3 is bent outwardly and extended to provide a clamping plate 35 , which passes through the introduction groove 42 and covers the cylindrical surface of the adjustment screw 5 .

[0022] The two sides of the fixed seat 3 are bent to form a plurality of guide grooves 36 , and correspondingly, the inner wall protrusion of the movable seat 4 is provided with a guide platform 44 , which is slidably buckled in the guide groove 36 and slides up and down along the guide groove 36 .

[0023] The movable seat 4 is elastically provided with a positioning column 43 , and the positioning column 43 presses against the end surface of the fixed seat 3 .

[0024] Working principle: Different from the traditional method of directly opening a buckle slot at the end of the drawer, in this case, a fixed seat and a movable seat slidably connected thereto are provided at the end of the drawer, the buckle slot is opened in the movable seat, and the hook at the end of the guide rail extends into the buckle slot to be connected and installed with the movable seat.

[0025] In order to adjust the height of the drawer tail, an adjusting screw is installed in the fixed seat, and correspondingly, a threaded adjusting groove is arranged on the movable seat. The adjusting screw and the threaded adjusting groove are meshed and assembled with each other. By rotating the adjusting screw, the thread on the cylindrical surface of the adjusting screw drives the threaded adjusting groove to slide, and drives the movable seat to move up and down along the fixed seat, and converts the rotational motion of the adjusting screw into linear motion of the movable seat, thereby achieving the purpose of adjusting the height of the drawer tail and quickly correcting the height of the drawer tail. The entire adjustment process does not require disassembly, and the adjustment operation is simple and quick, which is convenient for users to maintain the drawer, so that the drawer and the guide rail are always in the best working condition. Even if it is loose in the later stage, it can be quickly adjusted to ensure the long-term and stable operation of the drawer.

[0026] The structure of the adjusting screw and the threaded adjusting groove is flexible in design and compact in structure. It does not occupy any extra space between the drawer and the guide rail. It is suitable for use in systems of all types of drawer guide rails and has strong versatility and practicality.

[0027] Among them, an upper limit plate and a lower limit plate are arranged on the top of the fixed seat, and a limit groove is formed between the two limit plates. The bolt head of the adjusting screw is clamped in the limit groove, locking the axial movement of the adjusting screw. The adjusting screw can only perform rotational movement and cannot perform axial movement, ensuring that the movable seat can slide axially along the fixed seat, ensuring the stability and reliability of the adjustment process. A guide shaft is arranged at the bolt head of the adjusting screw, and at the same time, a clamping groove is opened in the upper limit plate, and the clamping groove is clamped and docked on the outer cylindrical surface of the guide shaft, further limiting the axial movement of the adjusting screw, enhancing the reliability of the adjusting screw, and preventing it from axial movement.

[0028] A splint is also provided in the fixed seat, which extends through the guide groove of the movable seat into the threaded adjustment groove, and covers and presses on the cylindrical surface of the adjusting screw, locking the radial movement of the adjusting screw, effectively preventing the adjusting screw from shaking during the adjustment process, and ensuring that the adjusting screw can only rotate around its own axis, thereby ensuring its long-term stability.

[0029] Multiple limit structures are set to limit 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 product's usage experience and service life.

[0030] In order to further ensure the sliding path of the movable seat, a number of guide grooves are bent on both sides of the fixed seat, and a guide platform is provided on the inner wall protrusion of the movable seat corresponding to the guide grooves. The guide platform is slidably buckled in the guide groove, and the guide platform slides up and down along the guide groove to limit the axial sliding path of the movable seat.

[0031] A positioning column is elastically arranged on the movable seat, and the positioning column is used to press against the end face of the fixed seat. The positioning column provides a certain friction between the movable seat and the fixed seat. After the height adjustment is completed, the friction force can effectively prevent the movable seat from moving due to external force, thereby ensuring that the adjustment position of the movable seat is stable and reliable, and enhancing the connection strength between the two, so it can be widely promoted.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
