Description

Technical Field

[0001] The utility model relates to a drawer guide rail, in particular to a detachable installation structure of a drawer synchronizer. Background Art

[0002] With the development of the modern furniture manufacturing industry, the design of home products has increasingly focused on aesthetics and functionality. Drawers, as an essential component of furniture, are becoming a focus of user attention for their smooth sliding, durability, and ease of installation. Currently, drawer guides are widely used in various furniture to provide the sliding function of drawers. Drawer guides typically consist of fixed rails and movable rails. The movable rails slide in contact with the fixed rails via rollers or sliders, enabling smooth opening and closing of the drawers. To ensure the synchronized movement of the drawer rails, synchronization mechanisms have been designed and implemented into the guide structures.

[0003] In the prior art, commonly used synchronization mechanisms usually use gears and racks to mesh to ensure the synchronous sliding of the guide rails on both sides when the drawer is opened and closed. However, this type of synchronization mechanism has the following shortcomings:

[0004] 1. Existing drawer rail synchronization mechanisms are mostly fixed directly to specific locations on the rail, making them difficult to adjust or replace based on actual needs. This structure limits the flexibility of the rail and makes the synchronization mechanism and rail inseparable. During the production process, manufacturers must design different specifications of synchronization mechanisms for different rail models to accommodate various drawer configurations. This not only increases production costs but also increases design complexity, especially when facing diverse market demands, requiring manufacturers to produce multiple models of rail products to meet the needs of different drawer specifications.

[0005] 2. Because existing synchronization mechanisms are fixed to the guide rails, if problems arise, such as gear wear or poor meshing, it's difficult for users or maintenance personnel to maintain or replace the synchronization mechanism alone. Often, the entire guide rail system must be replaced. This not only increases maintenance costs but also impacts the user experience. This is especially true for mass-produced furniture, where failure of the synchronization mechanism necessitates extensive guide rail replacement, resulting in significant waste.

[0006] 3. The existing design of the integrated guide rail and synchronizing mechanism complicates the production and assembly process. The synchronizing mechanism's fixed position and installation method must precisely match the guide rail's structure, which places high demands on assembly precision during production. Imprecise dimensions or significant deviations in any component can cause the synchronizing mechanism to be improperly installed, affecting the drawer's proper operation. This design not only increases manufacturing complexity but also complicates and costs factory inspection.

[0007] 4. With the diversification of the home furnishing market, users are demanding a wider range of furniture sizes and designs. Manufacturers must offer a wider range of drawer rails and synchronizing mechanisms to accommodate diverse market demands. Because the synchronizing mechanisms are fixed to the rails, manufacturers cannot flexibly adjust product specifications and configurations during production, forcing them to develop multiple models to accommodate diverse furniture designs. This complicates product line expansion, hinders large-scale production, and limits the design freedom of customized products.

[0008] In summary, existing drawer guide rail synchronization mechanisms have many deficiencies in structural design, production process, installation and maintenance, and adaptability, making it difficult to meet the market's demand for flexibility and efficient production. Therefore, further improvements are necessary. Utility Model Content

[0009] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a drawer synchronizer detachable installation structure with a simple structure, easy use, and the ability to realize flexible disassembly and assembly of the synchronization mechanism and the guide rail to adapt to guide rails of different specifications and models, simplify the production process and improve maintenance convenience.

[0010] The purpose of the utility model is achieved in the following way: a detachable mounting structure of a drawer synchronizer, which includes a mounting base fixed on a movable slide rail and a rack fixed on a fixed rail, wherein a gear is rotatably mounted in the mounting base and meshes with the rack, and when the movable slide rail moves, the meshing of the gear and the rack drives the synchronization shaft to rotate;

[0011] The side wall of the mounting seat is provided with a positioning buckle which is fastened and fixed with a positioning slot provided on the movable slide rail.

[0012] Furthermore: the mounting seat is also provided with a positioning boss, and the movable slide rail is provided with a corresponding positioning through hole, the positioning boss is inserted into the positioning through hole and connected thereto, and the positioning boss cooperates with the positioning buckle to fix the mounting seat on the movable slide rail.

[0013] Furthermore: the positioning buckle and positioning boss are arranged on the inner side wall of the mounting seat, and a covering plate is also provided on the top of the mounting seat, which extends toward the inner side wall and covers the upper end surface of the movable slide rail.

[0014] Furthermore: a docking seat is extended backward from the rear end of the mounting seat, and the docking seat is inserted into the rebound seat on the movable slide rail and connected thereto.

[0015] Furthermore: a concave accommodating cavity is provided at the bottom of the mounting seat, and the gear is mounted in the accommodating cavity through a rotating sleeve.

[0016] Furthermore: the rotating sleeve includes a first shell and a second shell installed relative to each other, a positioning shaft extends outward from one end of the gear, and a synchronization shaft extends outward from the other end. Correspondingly, a positioning hole for accommodating the positioning shaft and a synchronization hole for installing the synchronization shaft are respectively provided on the first shell and the second shell.

[0017] Furthermore: a plurality of connecting columns extend outwardly from the docking end surface of the first shell, and a connecting hole is provided on the docking surface of the second shell, and the connecting columns are inserted into the connecting hole for connection.

[0018] Furthermore: the side wall of the first shell extends outward with an elastic buckle, the side wall of the second shell is provided with a positioning buckle, and the elastic buckle is clamped on the positioning buckle for connection.

[0019] Furthermore, a clearance groove is provided at the bottom of the first shell and the second shell, and the gear extends out of the rotating sleeve through the clearance groove and engages with the rack.

[0020] Furthermore: the first shell and the second shell are relatively provided with clamping seats at positions corresponding to the avoidance grooves, and the rack is clamped in the clamping seats.

[0021] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0022] 2. The drawer synchronizer of this utility model utilizes a removable mounting structure, allowing for flexible connection between the synchronizer and the guide rail via snaps, bosses, and other devices. This allows for separate installation of the synchronizer mechanism and guide rail, eliminating the need for a separate synchronizer mechanism for each guide rail of varying specifications. This design effectively enhances the synchronizer's applicability, allowing the same synchronizer model to be used in a variety of guide rail systems of varying sizes and structures, greatly increasing the product's versatility.

[0023] 3. Because the synchronizer utilizes a modular, removable design, manufacturers no longer need to design a separate synchronization mechanism for each guide rail specification. The synchronizer and guide rail can be produced independently and then combined as needed during subsequent assembly. This not only simplifies product design and manufacturing, but also reduces mold development and manufacturing costs. Furthermore, the standardized and modular design facilitates large-scale production and reduces production costs.

[0024] 4. The detachable design allows the synchronizer to be removed and replaced individually within the guide rail system, eliminating the need to replace the entire guide rail structure. If the synchronizer mechanism experiences a problem or requires an upgrade, the user or maintenance personnel can easily remove the synchronizer for maintenance or replacement, significantly improving maintenance convenience and affordability. This design reduces maintenance costs while extending the life of the guide rail and enhancing the user experience.

[0025] 5. This utility model's flexible, detachable structural design allows it to adapt to different types of guide rail systems. Whether rails have varying widths, lengths, or heights, they can be flexibly installed simply by adjusting the synchronizer's mounting position or accessories. This feature is particularly well-suited to the customized needs of the furniture manufacturing industry, providing flexible solutions for diverse furniture designs.

[0026] 6. Because the synchronizer can be installed separately from the guide rail, this significantly increases design freedom. Manufacturers can adjust the coordination between the synchronizer and the guide rail based on specific furniture requirements, freeing them from the constraints of a synchronizer fixed to the guide rail. This design not only meets diverse product needs but also allows furniture designers to design drawers of varying styles and sizes with greater freedom. BRIEF DESCRIPTION OF THE DRAWINGS

A detachable mounting structure for a drawer synchronizer includes a mounting base 2 fixed to a movable rail 1 and a rack 4 fixed to a fixed rail 3. A gear 5 is rotatably mounted within the mounting base 2 and meshes with the rack 4. When the movable rail 1 moves, the meshing of the gear 5 and the rack 4 drives a synchronizer shaft 6 to rotate.

[0033] The side wall of the mounting seat 2 is provided with a positioning buckle 21 which is fastened and fixed with the positioning slot 11 provided on the movable slide rail 1.

[0034] Furthermore: the mounting seat 2 is also provided with a positioning boss 22, and the movable slide rail 1 is provided with a corresponding positioning through hole 12. The positioning boss 22 is inserted into the positioning through hole 12 and connected thereto. The positioning boss 22 cooperates with the positioning buckle 21 to fix the mounting seat 2 on the movable slide rail 1.

[0035] In one embodiment, the positioning buckle 21 and the positioning boss 22 are arranged on the inner wall of the mounting seat 2, and a covering plate 23 is also provided on the top of the mounting seat 2. The covering plate 23 extends toward the inner wall, and the covering plate 23 is arranged to cover the upper end surface of the movable slide rail 1.

[0036] In one embodiment, a docking seat 24 is extended backward from the rear end of the mounting seat 2 , and the docking seat 24 is inserted into the rebound seat 7 on the movable slide rail 1 and connected thereto.

[0037] In one embodiment, a concave accommodating cavity 25 is provided at the bottom of the mounting seat 2 , and the gear 5 is mounted in the accommodating cavity 25 via a rotating sleeve 8 .

[0038] In one embodiment, the rotating sleeve 8 includes a first shell 81 and a second shell 82 that are installed relative to each other. A positioning shaft 51 extends outward from one end of the gear 5, and a synchronization shaft 6 extends outward from the other end. Correspondingly, a positioning hole 83 for accommodating the positioning shaft 51 and a synchronization hole 84 for installing the synchronization shaft 6 are respectively provided on the first shell 81 and the second shell 82.

[0039] In one embodiment, a plurality of connecting posts 85 extend outwardly from the docking end surface of the first shell 81, and a connecting hole is provided on the docking surface of the second shell 82, into which the connecting posts 85 are inserted for connection.

[0040] In one embodiment, the side wall of the first shell 81 extends outward with an elastic buckle 86 , and the side wall of the second shell 82 is provided with a positioning buckle 87 , and the elastic buckle 86 is clamped on the positioning buckle 87 for connection.

[0041] In one embodiment, a clearance groove 88 is provided at the bottom of the first shell 81 and the second shell 82 , and the gear 5 extends out of the rotating sleeve 8 through the clearance groove 88 to engage with the rack 4 .

[0042] In one embodiment, the first shell 81 and the second shell 82 are provided with clamping seats 89 at positions corresponding to the avoidance grooves 88 , and the rack 4 is clamped in the clamping seats 89 .

[0043] Working Principle: This utility model provides a removable installation structure for a drawer synchronizer, primarily used for the synchronization mechanism of a drawer rail system. Its basic principle is to achieve synchronized movement between the movable and fixed rails through the meshing of a gear and rack, ensuring that the rails on both sides of the drawer remain synchronized during opening and closing. The following is the specific working principle of this device and its related technical advantages:

[0044] Specifically, the mounting structure includes a mounting base 2 fixed to a movable rail 1 and a rack 4 fixed to a fixed rail 3. A gear 5 is mounted within the mounting base 2 and meshes with the rack 4. When the user pushes the drawer, the movable rail 1 moves along the fixed rail 3, and the meshing of the gear 5 with the rack 4 causes the gear 5 to rotate.

[0045] The rotation of gear 5 is transmitted through a synchronizing shaft 6 at one end, which is connected to the other side of the guide rail. This synchronization mechanism ensures the synchronized movement of both guide rails when the drawer is opened and closed. Regardless of the forces acting on the left and right sides of the drawer, the coordination of the gear and rack ensures smooth, synchronized slide of the drawer, preventing tilting or jamming caused by inconsistent movement on both sides.

[0046] Therefore, through the precise meshing of the gear and rack, high-precision synchronization of the drawer rails can be achieved, ensuring that the drawer remains stable and smooth even during wide opening and closing. The synchronous control of the gear and rack is particularly significant in applications with wider drawers. Compared to existing fixed synchronization mechanisms, the removable structure designed in this utility model can accommodate guide rails of different models and specifications, increasing production and assembly flexibility.

[0047] It should be noted that the mounting base 2 is secured to the positioning slot 11 on the movable rail 1 via a positioning clip 21. Furthermore, the mounting base 2 is provided with a positioning boss 22, which inserts into the positioning hole 12 on the movable rail 1. This dual positioning of the clip and boss secures the mounting base 2 to the movable rail 1, ensuring that the synchronizer does not loosen or shift during rail movement.

[0048] This multi-point positioning design not only improves installation reliability, but also simplifies installation operations, making synchronizer assembly and disassembly more convenient. Even under long-term use or heavy loads, the positioning device can maintain a stable connection between the synchronizer and the guide rail.

[0049] The synchronizer of this utility model adopts a removable structure. The gear 5 is mounted within the recessed accommodating cavity 25 at the bottom of the mounting base 2 via a rotating sleeve 8. The rotating sleeve 8 comprises a first housing 81 and a second housing 82, which are mounted opposite each other and secured via connecting posts 85 and connecting holes. Furthermore, elastic buckles 86 and positioning buckles 87 are provided on the first and second housings 81, 82 to ensure a secure connection of the synchronizer.

[0050] One end of gear 5 is fixed by a positioning shaft 51, and the other end is connected to the synchronization shaft 6. Gear 5 meshes with rack 4 via a clearance groove 88. This design allows for easy disassembly of the synchronizer, facilitating replacement and maintenance. If the gear, rack, or other components become damaged, the user or maintenance personnel can replace them individually without having to dismantle the entire guide rail system.

[0051] The removable design facilitates repair and maintenance, significantly reducing repair costs. Users no longer need to replace the entire guide rail system; only damaged synchronizer components need to be replaced, extending the life of the equipment. Furthermore, the modular design facilitates standardized production of synchronizers and guide rails, reducing compatibility issues between different guide rail models.

[0052] This utility model's removable drawer synchronizer installation structure, through the meshing of the gear and rack, the stable fixation of the positioning device, the modular removable design, and auxiliary structures such as the cover plate, successfully achieves efficient transmission between the synchronizer and the guide rail system, convenient installation and maintenance, and the flexibility to adapt to different guide rail models, greatly improving the performance and reliability of the guide rail system. In modern furniture manufacturing, this utility model provides a more adaptable and economical solution for drawer synchronizers.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
