Description

Technical Field

[0001] The invention relates to the technical field of drawer connecting devices, in particular to a drawer connecting device with front-back adjustment. Background Art

[0002] At present, drawers are equipped with slide rails. No matter the slide rails are two-section or three-section, the fixed rails are generally installed on the cabinet body, and the movable rails are installed on the drawers. The movable rails and fixed wheels slide relative to each other to realize the opening and closing movement of the drawers.

[0003] Among them, the slide rail is generally installed with the drawer using a connecting device. The above-mentioned connecting device includes a fixed seat, an adjusting seat, and a buckle. The fixed seat is installed at the bottom of the drawer, the adjusting seat is positioned and slidably mounted on the fixed seat, and the buckle is rotatably connected to the adjusting seat and buckled with the movable rail. Although the installation position between the drawer and the slide rail can be adjusted to a certain extent, the traditional connecting device generally has the following shortcomings in actual application:

[0004] 1) The connection device has a complex structure and poor stability, which can easily lead to deviations from the assembly of the slide rail and drawer, reducing precision and affecting the assembly effect of the drawer, and even preventing the drawer from opening and closing normally, affecting the normal use of the drawer.

[0005] 2) When the connecting device adjusts the front and rear positions of the slide rail and the drawer, it actually adjusts the front and rear positions of the movable rail and the fixed rail, which will reduce the buffer distance and effect of the slide rail and reduce the use effect of the drawer. In addition, the long-term direct contact between the connecting device and the fixed rail is likely to affect the service life.

[0006] 3) The connection device generally uses a torsion spring as the driving force. If the torque is too small, the handle cannot be reset normally after disassembly. If the torque is too large, a large unlocking force is required to complete the unlocking.

[0007] 4) The connection device generally requires turning a buckle handle to rotate in order to separate the slide rail and the drawer. However, the buckle handle is generally located on one side of the slide rail, and the contact area with human fingers is too small, making it difficult to find and requiring a large operating force, making disassembly and assembly difficult, affecting the quality of use of the drawer.

[0008] 5) The motion trajectory of the handle in the connecting device is generally converted from linear movement to vertical linear movement, which can easily cause the handle to get stuck during the disassembly and assembly process, making it impossible to complete the disassembly and assembly smoothly.

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] According to the attached Figures 1 to 6 As shown, the drawer connection device with front and rear adjustment of the present invention includes a fixed seat 1, an adjustment seat 2 and a handle lock 3. The fixed seat 1 is installed in the drawer, and the adjustment seat 2 is installed in the movable rail of the slide rail. The fixed seat 1 is provided with an adjustment wheel 4, and the adjustment wheel 4 is rotatably connected to the fixed seat 1. The front end of the adjustment seat 2 is slidably mounted on the fixed seat 1 and is threadedly connected to the adjustment wheel 4. The handle lock 3 is axially connected to the middle part of the adjustment seat 2, and one side of the handle lock 3 has an elastic connection part 32. The elastic return action of the elastic connection part 32 allows the handle lock 3 to extend out of the adjustment seat 2 and always lock on the movable rail.

[0039] At the same time, an unlocking elastic assembly 5 is provided in the middle of the adjustment seat 2. The unlocking elastic assembly 5 slides on the adjustment seat 2 along the opening and closing direction of the drawer and pushes the handle lock 3 to rotate around the axis connection point toward the elastic connection part 32, so that the handle lock 3 is compressed into the adjustment seat 2 and separated from the movable rail.

[0040] Reference Figures 1 to 6As shown in further detail, the upper surface of the adjustment base 2 is provided with a mounting slot 6, which is provided with an elastic clamping column 7. The handle lock 3 is provided with a fixing hole 34 that is matched with the elastic clamping column 7 and can rotate around the elastic clamping column 7. The bottom surface of the adjustment base 2 is provided with a limiting slide 24 for facilitating the sliding of the unlocking elastic assembly 5. The limiting slide 24 is provided with a positioning clamping column 25 that is elastically connected to the unlocking elastic assembly 5.

[0041] Among them, one side of the swinging end of the handle lock 3 is provided with a buckling portion 31 for buckling the movable rail, and the other side of the swinging end of the handle lock 3 is provided with an elastic connecting portion 32 that is clamped on one side of the drawer; and the bottom surface of the handle lock 3 is provided with a connecting column 33 connected to the unlocking elastic assembly 5.

[0042] The adjustment base 2 is also provided with a guide arc groove 26 for the connecting column 33 to pass through the adjustment base 2, and a notch 27 for the buckle 31 to extend or retract as the handle lock 3 rotates. The inner side of the notch 27 is provided with an inner protrusion 28 that limits the outward extension position of the buckle 31. The inner protrusion 28 is movably connected to the swing end of the handle lock 3.

[0043] Furthermore, the fixing base 1 is provided with a mounting hole 13. Mounting screws 14 are installed in the mounting hole 13 for securing the drawer. The front end of the adjustment base 2 is provided with a threaded guide post 23 that is threadedly connected to the adjustment wheel 4. The fixing base 1 is equipped with a limit buckle 11 for directional forward and backward sliding of the threaded guide post 23 and a mounting slot 12 for rotational connection with the adjustment wheel 4. The limit buckles 11 are located at the front and rear ends of the mounting slot 12.

[0044] Furthermore, the adjustment seat 2 is provided with a limiting guide block 21. A guide groove 22 is formed between the limiting guide block 21 and one side of the adjustment seat 2 and is clamped on the end of the movable rail and moves forward and backward along the movable rail.

[0045] During assembly, the fixing base 1 is secured to the drawer by fitting the mounting screws 14 into the mounting holes 13. Then, when installing the drawer, the handle lock 3 slides along with the drawer onto the movable rail of the slide. When moved to a specific position, the movable rail slides into the guide slot 22, allowing the limiting guide block 21 to be inserted into the movable rail.

[0046] At this time, the elastic connecting portion 32 of the handle lock 3 is clamped on one side of the drawer, and under the elastic action of the elastic connecting portion 32, it obtains elastic energy for self-rotation, and the buckling portion 31 of the handle lock 3 is connected to the adjustment seat 2 with the elastic clamping column 7 as the point of fixed rotation, and the buckling portion 31 of the handle lock 3 always extends out of the notch 27 and is locked on the movable rail, so that the buckling portion 31 of the handle lock 3 can always maintain a locked state.

[0047] During assembly, you only need to rotate the adjusting wheel 4 to drive the threaded guide column 23 to move forward or backward, thereby adjusting the front and rear installation position of the adjusting seat 2 relative to the fixed seat 1, so as to adjust the front and rear installation position of the drawer. The structure is simple, improves the assembly precision, strengthens the structural stability, and ensures the quality of the drawer.

[0048] Reference Figures 1 to 6 As shown, the unlocking elastic assembly 5 includes an unlocking slider 51 and an unlocking elastic member 52. The unlocking elastic member 52 is longitudinally mounted between the unlocking slider 51 and the adjustment base 2, with its ends respectively pressing against the positioning posts 25 of the adjustment base 2 and the positioning posts of the unlocking slider 51. Driven by the dual elastic structure of the elastic connection portion 31 of the handle lock 3 and the unlocking elastic member 52 of the unlocking elastic assembly 5, easy assembly and disassembly is achieved while ensuring that the handle lock 3 remains locked, thereby ensuring a more secure and tight connection between the drawer slides.

[0049] The unlocking elastic assembly 5 is provided with a sector-shaped arc groove 54 for driving the swing end of the handle lock 3 to rotate, and the connecting column 33 is connected to the sector-shaped arc groove 54 by sliding in an arc manner.

[0050] In the optimized solution, the unlocking slider 51 is provided with an operating slot 53 for easy assembly and disassembly, and a fan-shaped arc groove 54 for guiding the sliding of the connecting post 33. In this way, the fan-shaped arc groove 53 and the trajectory of the connecting post 33 of the handle lock 3 cooperate to ensure smooth assembly and disassembly and rotation of the handle lock 3.

[0051] To this end, under the action of the unlocking elastic assembly 5, the unlocking elastic assembly is simply pushed to slide on the adjustment base 2 to compress the unlocking elastic member 52, converting linear motion into rotational motion, causing the unlocking slider 51 to rotate in conjunction with the swinging end of the handle lock 3. At this time, the connecting post 33 slides along the fan-shaped arc groove 53 into the adjustment base 2, causing the buckling portion 31 of the handle lock 3 to retract and disengage from the movable rail, completing the unlocking process. This facilitates quick and easy separation of the drawer and the slide rail, ensuring normal use of the drawer.

[0052] The unlocking slider 51 is provided with an operating slot 53 for easy assembly and disassembly. The shape of the operating slot 53 matches the shape of a human finger. The operator can easily push the unlocking slider 51 forward by placing two fingers on the operating slot 53. This eliminates the need for blind searching, facilitates operation, and allows for quick disassembly.

[0053] Reference Figures 1 to 6 As shown, the adjustment seat 2 is provided with an elastic block 8 connected to the end of the movable rail. The elastic block 8 is located in front of the unlocking elastic member 52, and the direction of the elastic action of the elastic block 8 is consistent with the movement direction of the adjustment seat 2. The end of the elastic block 8 is always in surface contact with the movable rail of the slide rail.

[0054] When adjusting the drawer assembly state or the drawer opening and closing state, the elastic action of the elastic block 8 ensures that the movable rail is always in contact with the end surface of the elastic block 8 during assembly, which has a good buffering effect, reduces collisions, increases the pressure resistance area, reduces the probability of deformation, and ensures the quality of the slide rail.

[0055] The above specific embodiments are only specific implementation methods with better effects of the present invention. Any structure that is the same or equivalent to the drawer connecting device with front-back adjustment of the present invention is within the protection scope of the present invention.
