Description

Technical Field

[0001] This utility model relates to the technical field of slide rail interlocking devices, and in particular to an interlocking device for multi-layer drawer slide rails. Background Technology

[0002] In daily life and work, multi-drawer chests are widely used for storing various items. However, traditional multi-drawer slide systems have some drawbacks: when a user pulls out one drawer, the center of gravity of the cabinet changes, but due to the lack of an effective interlocking mechanism, while one drawer is being pulled out, the other drawers remain freely movable. This leads to poor overall stability of the cabinet, making it prone to tipping over, which may not only damage the items inside but also threaten the safety of people nearby.

[0003] Furthermore, during the installation and use of the drawer slide system, installation gaps inevitably exist between the components. For example, the installation gap between the connecting rod and the adjusting block may prevent the locking head from accurately and effectively engaging with the fixed part when the connecting rod pushes the locking head, potentially affecting the normal use of the interlocking function. The reliability and stability of the drawer slide system need further improvement. Although existing technologies have drawer slide interlocking devices with adjusting components, the drawer box needs to be completely removed for adjustment, which may result in low adjustment efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an interlocking device for multi-layer drawer slides.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An interlocking device for multi-layer drawer slides includes slides mounted on a cabinet body, with a drawer box connected to the slides. The slides include an outer rail, a middle rail, and an inner rail. The middle rail is slidably connected to the outer rail, the inner rail is slidably connected to the middle rail, and the inner rail is fixedly connected to the side wall of the drawer box. The device also includes:

[0007] The fixing part is fixedly connected to the inner rail;

[0008] The locking head is slidably connected to the outer rail;

[0009] When the locking end of the locking head slides into the outer rail, the locking end of the locking head abuts against the fixing part on the inner rail;

[0010] A connecting rod is connected to the locking head;

[0011] An adjusting block is slidably connected to the locking head, and the adjusting block abuts against the connecting rod.

[0012] Preferably, a pad is fixedly connected to the adjusting block, and an adjusting screw is rotatably connected to the pad, the adjusting screw being threadedly connected to the locking head.

[0013] Furthermore, an adjusting rod is rotatably connected to the adjusting block, a first adjusting tooth is fixedly connected to the adjusting rod, and a second adjusting tooth is fixedly connected to the bottom of the adjusting screw, wherein the first adjusting tooth and the second adjusting tooth mesh with each other.

[0014] Compared with the prior art, this utility model provides an interlocking device for multi-layer drawer slides, which has the following advantages:

[0015] The parts of this device not described herein are the same as or can be implemented using existing technology. When a single drawer box is pulled out, the drawer box slides along the inner rail, causing the remaining locking heads to slide and extend into the corresponding slide rails, abutting against the fixing parts on the inner rails. This interlocks the remaining slide rails, ensuring that the cabinet's center of gravity does not shift significantly when multiple drawer boxes are pulled out simultaneously. This effectively enhances the stability of the cabinet, avoids the risk of the cabinet tipping over, and provides a safer and more reliable user environment. Furthermore, this invention uses the adjustment rod to rotate, which in turn rotates the adjustment screw, allowing the adjustment rod to slide and adjust. This adjustment method eliminates the need to disassemble the entire drawer for adjustment; simply pull out the drawer box and use a tool to rotate the adjustment rod to complete the adjustment, effectively improving adjustment efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1:

[0027] Reference Figures 1-8 An interlocking device for multi-layer drawer slides includes slides mounted on a cabinet body 8, with a drawer box 801 connected to the slides. The slides include an outer rail 1, a middle rail 2, and an inner rail 3. The middle rail 2 is slidably connected to the outer rail 1, and the inner rail 3 is slidably connected to the middle rail 2. The inner rail 3 is fixedly connected to the side wall of the drawer box 801. The device also includes:

[0028] The fixing part 301 is fixedly connected to the inner rail 3;

[0029] Locking head 6 is slidably connected to outer rail 1;

[0030] When the locking end of the locking head 6 slides into the outer rail 1, the locking end of the locking head 6 abuts against the fixing part 301 on the inner rail 3.

[0031] A connecting rod 4 is connected to the locking head 6;

[0032] Adjusting block 5 is slidably connected to locking head 6, and adjusting block 5 abuts against connecting rod 4.

[0033] A pad 502 is fixedly connected to the adjusting block 5, and an adjusting screw 7 is rotatably connected to the pad 502. The adjusting screw 7 is threadedly connected to the locking head 6.

[0034] An adjusting rod 501 is rotatably connected to the adjusting block 5, and a first adjusting tooth 5011 is fixedly connected to the adjusting rod 501. A second adjusting tooth 701 is fixedly connected to the bottom of the adjusting screw 7, and the first adjusting tooth 5011 meshes with the second adjusting tooth 701.

[0035] Reference Figures 1-8 During use, when the middle drawer box 801 is pulled out, the drawer box 801 will cause the inner rail 3 to slide. The sliding of the inner rail 3 will cause the fixing part 301 and the middle rail 2 to slide out. At this time, the locking heads 6 at the top and bottom ends will be squeezed and slid. After being squeezed, the locking heads 6 will extend into the slide rails at the top and bottom ends. At this time, the locking heads 6 will abut against the fixing parts 301 on the inner rails 3 at the top and bottom ends. The locking heads 6 abut against the fixing parts 301, and the drawer boxes 801 at the top and bottom ends will not be able to be pulled out. This ensures that when a single drawer box 801 is pulled out, the other drawer boxes 801 can be stably stored in the cabinet body 8, effectively solving the problem in the prior art that when the drawer box 801 is pulled out, the center of gravity of the cabinet body 8 changes and it is easy to tip over.

[0036] During the use of drawer box 801, when there is an installation gap between the connecting rod 4 and the adjusting block 5, the connecting rod 4 may not be able to effectively abut the locking head 6 against the fixing part 301 when pushing the locking head 6. At this time, the operator can use a screwdriver to rotate the adjusting rod 501. The adjusting rod 501 will drive the adjusting screw 7 that is engaged with it to rotate. The rotation of the adjusting screw 7 will drive the adjusting block 5 to slide on the locking head 6, so that the adjusting block 5 can tightly abut against the connecting rod 4, thereby ensuring that the locking head 6 can stably abut against the fixing part 301 when the drawer box 801 is pulled out.

[0037] This application achieves adjustment by rotating the adjusting rod 501, which in turn drives the adjusting screw 7 to rotate, thereby causing the adjusting rod 501 to slide and adjust. This adjustment method eliminates the need to disassemble the entire drawer for adjustment; simply pull out the drawer box 801 and use a tool to rotate the adjusting rod 501 to complete the adjustment, effectively improving adjustment efficiency.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
