[0002] Currently, drawers are installed with slide rails. Whether the slide rails are two-stage or three-stage, the common fixed rails are installed on the cabinet body, and the movable rails are installed on the drawers. The opening and closing movement of the drawers is realized by the relative sliding of the movable rails and the fixed wheels.

[0003] Among them, the slide rails are generally installed in cooperation with the drawers by connection devices. The above connection devices include a fixed seat, an adjustment seat, and a buckle handle. The fixed seat is installed at the bottom of the drawer, the adjustment seat is positioned and slidably installed on the fixed seat, and the buckle handle is rotatably connected to the adjustment seat and is buckled with the movable rail in cooperation. Although the installation position between the drawer and the slide rail is adjusted to a certain extent, the traditional connection devices generally have the following deficiencies in practical applications:

[0004] 1) The structure of the connection device is relatively complex, and the stability is poor. It is easy to deviate from the assembly of the slide rail and the drawer, reducing the precision, affecting the assembly effect of the drawer, and even unable to open and close normally, affecting the normal use of the drawer.

[0005] 2) When the connection device adjusts the front and back positions of the slide rail and the drawer, it actually adjusts the front and back positions of the movable rail and the fixed rail, which will reduce the buffer distance and effect of the slide rail, reduce the use effect of the drawer, and the connection device is in direct contact with the fixed rail for a long time, which is easy to affect the service life.

[0006] 3) The connection device generally needs to rotate the buckle handle to disassemble the slide rail and the drawer. However, the buckle handle is generally arranged on one side of the slide rail, and the contact area with the human finger is too small, making it difficult to find and requiring a large operating force, resulting in difficult disassembly and assembly, and affecting the use quality of the drawer.

The fixed part of the front - rear adjustment assembly 1 is installed at the bottom of the drawer, and the movable part of the front - rear adjustment assembly 1 is clamped at the front end of the movable rail of the slide rail. The handle lock 2 is rotatably connected to the front - rear adjustment assembly 1 and is buckled on the movable rail of the slide rail under its elastic action. The fixed part of the adaptive assembly 3 is installed on the back panel of the drawer, and a hook 5 is provided at the end of the movable rail of the slide rail, and the hook 5 is buckled on the movable part of the adaptive assembly 3. Moreover, a front elastic member 6 for connecting with the front end of the movable rail of the slide rail is provided on the movable part of the front - rear adjustment assembly 1, a rear elastic member 7 for connecting with the rear end of the movable rail of the slide rail is provided on the adaptive assembly 3, and the elastic forces of the front elastic member 6 and the rear elastic member 7 are set in opposite directions. The unlocking elastic assembly 4 is slidably installed on the front - rear adjustment assembly 1, and the swing end of the handle lock 2 is connected to the unlocking elastic assembly 4.

[0038] Refer to Figures 1 to 10As shown, for further refinement, the front and rear adjustment assembly 1 includes a mounting base 11, a front and rear adjustment base 12, and an adjustment wheel 13. The mounting base 11 is installed at the bottom of the drawer. The front and rear adjustment base 12 is slidably connected to the mounting base 11. The adjustment wheel 13 is rotatably connected to the mounting base 11. The front elastic member 6 is provided at the front end of the front and rear adjustment base 12. Moreover, a threaded column 14 threadedly connected to the adjustment wheel 13 and a clamping block 15 clamped to the front end of the movable rail are provided at the front end of the front and rear adjustment base 12.

[0039] The front and rear adjustment base 12 is provided with a positioning column 16 rotatably connected to the handle lock 2. The handle lock 2 is provided with a buckling portion 21 for buckling or disengaging from the movable rail of the slide rail and an elastic handle 22 connected to the drawer. The buckling portion 21 and the elastic handle 22 are respectively provided on both sides of the swinging end of the handle lock 2. With the structural cooperation between the elastic handle 22 and the buckling portion 21 of the handle lock 2, the handle lock 2 obtains the elastic energy for self-rotation, so that the handle lock 2 can always maintain the locked state, and forms a double elastic energy source with the unlocking elastic member, strengthening the locking performance of the handle lock 2 buckled on the slide rail, improving the connection stability between the slide rail and the drawer, and being convenient for disassembly and assembly and use.

[0040] During assembly, the mounting base 11 is installed at the bottom of the drawer, the front and rear adjustment base 12 is clamped on the movable rail. When the adjustment wheel 13 is rotated, the threaded column 14 can be driven to move forward or backward, so that the front and rear adjustment base 12 slides back and forth on the mounting base 11 to adjust the front and rear positions of the drawer after installation. The structure is simple, the assembly precision is improved, the structural stability is strengthened, and the use quality of the drawer is guaranteed.

[0041] In addition, the adaptive assembly 3 includes an adaptive fixed seat 31 and an adaptive adjustment seat 32. The adaptive fixed seat 31 is installed on the back panel of the drawer.

During this period, due to the opposite elastic forces of the front elastic member 6 and the rear elastic member 7, the vertical surface 33 of the self-adaptive adjusting seat 32 is always in surface contact with the hook 5 under the elastic action of the rear elastic member 7. In this way, the adjusting device of this structure has a good buffering effect, reduces collisions, eliminates noise, can also increase the compressive area, avoids the generation of gaps, reduces the probability of deformation, and ensures the assembly and use quality of the drawer.

[0044] In addition, a corrugated convex position 81 for contacting the hook 5 is provided in the fastening hole 8. Under the action of the corrugated convex position 81, the connection stability between the hook 5 and the fastening hole 8 is improved, and at the same time, the concentrated stress can be dispersed, the compressive strength can be enhanced, deformation can be avoided, and the normal use of the slide rail can be ensured.

[0045] Refer to Figures 1 to 6 As shown, the unlocking elastic combination 4 includes an unlocking elastic member 41 and an unlocking slider 42. The unlocking slider 42 is slidably mounted on the front and rear adjusting seat 12 of the front and rear adjusting assembly 1, and both ends of the unlocking elastic member 41 are respectively connected to the front and rear adjusting seat 12 and the unlocking slider 42. Among them, a connecting column 23 for separating the fastening portion 21 from the movable rail is provided at the swinging end of the handle lock 2 under the push of the unlocking slider 42, and the connecting column 23 is connected to the unlocking slider 42.

[0046] That is, under the action of the unlocking elastic combination 4, as long as the unlocking elastic component is pushed on the unlocking slider 42 to compress the unlocking elastic member 41, the swinging end of the handle lock 2 is rotated in linkage with the unlocking slider 42, and the fastening portion 21 of the handle lock 2 is separated from the movable rail, realizing the unlocking step, which is convenient for the quick disassembly of the drawer and the slide rail, easy to operate, and ensures the normal use of the drawer. [[ID=!!13]]

[0047] Among them, the unlocking slider 42 is provided with an unlocking groove position 43 for easy control, and the unlocking groove position 43 is distributed on the bottom surface of the unlocking slider 42. The shape of the unlocking groove position 43 conforms to the shape of a human finger. When two fingers of an operator are placed on the unlocking groove position 43, the unlocking slider 42 can be easily pushed forward. This avoids blind searching, is easy to operate, and enables quick disassembly.
