A quick-connect mechanism for drawer slide dampers

Abstract

A quick-connect mechanism for a drawer slide buffer includes several connecting posts mounted on the slide slide. The buffer has a connecting groove for accommodating the connecting posts, and several undercuts on the sidewalls of the connecting groove press against the connecting posts. The undercuts and the connecting groove together form a limiting zone, fixing the connecting posts and the buffer together within the limiting zone. The advantages of this invention are: by using a connecting groove on the buffer to accommodate the connecting posts on the slide slide, and cleverly utilizing the undercuts on the sidewalls of the connecting groove to automatically press against and form a limiting zone when the connecting posts are inserted, the connecting posts and the buffer are fixed together. The entire installation process requires no tools; the user only needs to align the buffer with the connecting posts and apply a pushing force to achieve a quick and convenient connection. This greatly simplifies the installation process.

Description

Technical Field

[0001] This utility model relates to the field of hardware accessories technology, specifically a quick connection mechanism for drawer slide buffers. Background Technology

[0002] Drawer slides are widely used in modern furniture and office equipment. To enhance the user experience, they are often integrated with a damping function to ensure smooth and quiet drawer closure. This requires the installation of a damper on the slide. The connection method between the damper and the slide directly affects the product's installation efficiency, ease of maintenance, and overall lifespan.

[0003] In existing technologies, the connection mechanisms of drawer slide buffers generally have some shortcomings. A common connection method is to set metal bending clips on the slide rail or on the buffer, and then connect them to the slide rail or the fasteners on the slide rail by bending, snapping, or pressing the metal clips.

[0004] However, this connection method based on metal bending clips has the following obvious drawbacks: 1. Low installation efficiency, requiring specialized tools: When installing the buffer, tools such as pliers and screwdrivers are usually needed to bend, pry, or press the metal clips to fix the buffer to the slide rail. This not only increases the complexity of the installation process and prolongs the installation time, but also places certain demands on the skills of the installers, making it inconvenient for ordinary consumers to install themselves, and also increases labor costs during mass production.

[0005] 2. Difficult disassembly, inconvenient or even impossible maintenance and replacement: Once the buffer is damaged or requires maintenance or replacement, the metal clips are often bent or deformed during installation, making their structure somewhat irreversible or destructive. This means that disassembly may require greater force or additional tools, and could even damage the clips or the slide rail itself. In many cases, a damaged buffer cannot be easily removed and replaced individually, forcing the user to replace the entire slide rail assembly, thus increasing maintenance costs and wasting resources, and reducing the product's lifespan and maintainability.

[0006] 3. Limited connection reliability and susceptible to fatigue: After repeated stress or prolonged use, metal bending buckles are prone to material fatigue and deformation, leading to loose connections and buckle failure, which in turn affects the normal function of the buffer and may even cause them to fall off during use, reducing the reliability and stability of the connection. Therefore, it is necessary to make further improvements. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a quick-connect mechanism for drawer slide dampers that is more compact in structure, more reliable in function, can be installed quickly without tools, and is convenient for later replacement, so as to improve the overall performance of the product and the user experience. The quick-connect mechanism for drawer slide dampers includes a mechanism installed on the slide rail.

[0008] The purpose of this utility model is achieved in the following way: a quick connection mechanism for a drawer slide rail damper, which includes several connecting posts installed on the slide rail, a connecting groove provided on the damper, the connecting groove being used to accommodate the connecting posts, and several buckles provided on the side wall of the connecting groove, the buckles pressing against the connecting posts, the buckles and the connecting groove forming a limiting area, fixing the connecting posts and the damper located in the limiting area as one unit.

[0009] Furthermore: the connecting groove is an arc-shaped inner groove, and a V-shaped groove is provided at the top of the connecting groove, which penetrates the upper end surface of the buffer.

[0010] Furthermore: the two buckles are arranged in a pair, symmetrically on both sides of the V-groove, with the free end of the buckle extending into the connecting groove.

[0011] Furthermore: the aforementioned undercut is provided in two pairs, symmetrically distributed in the V-groove, with a partition between the two pairs of undercuts. Correspondingly, the end face of the connecting column is provided with a limiting boss, which is snapped onto the partition.

[0012] Furthermore, at least two connecting columns are provided, which are distributed at intervals on the slide rail.

[0013] Furthermore, the connecting column is fixed to the slide rail by welding.

[0014] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0015] 2. This utility model utilizes a connecting groove on the buffer to accommodate the connecting column on the slide rail. The ingenious design employs the overhanging sidewalls of the connecting groove to automatically press and form a limiting zone when the connecting column is inserted, thus fixing the connecting column and the buffer together. The entire installation process requires no tools; the user simply aligns the buffer with the connecting column and applies a pushing force for a quick and convenient connection. This greatly simplifies the installation steps, improves installation efficiency, and reduces the skill requirements for installers, bringing significant convenience to both manufacturers' mass assembly and end-user self-installation.

[0016] 3. Compared to existing technologies where metal clips are difficult to disassemble after bending, this invention achieves both rapid installation and convenient disassembly. Through a rationally designed connecting groove and buckle structure, the buffer can be non-destructively separated from the connecting post when needed. This allows users to easily disassemble the buffer for individual repair or replacement when it is damaged or requires maintenance or replacement, without damaging the slide rail body or other components. This significantly reduces maintenance costs and replacement difficulty, effectively extends product lifespan, and reduces resource waste.

[0017] 4. This utility model securely fixes the connecting post inside the buffer by using a limiting area formed by the inverted buckle and the connecting groove, avoiding the connection loosening problem caused by fatigue deformation of traditional metal buckles. The pressing action of the inverted buckle on the connecting post ensures the tightness and stability of the connection, maintaining a reliable connection even with frequent opening and closing of the drawer, ensuring the normal functioning of the buffer, and improving the overall reliability of the product and user experience.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. A quick connection mechanism for a drawer slide rail damper includes a plurality of connecting posts 2 mounted on a slide rail 1, and a connecting groove 4 provided on a damper 3. The connecting groove 4 is used to accommodate the connecting posts 2, and a plurality of buckles 5 are provided on the side wall of the connecting groove 4. The buckles 5 press against the connecting posts 2, and the buckles 5 and the connecting groove 4 together form a limiting area 6, fixing the connecting posts 2 and the damper 3 located in the limiting area 6 as a whole.

[0025] In this embodiment: when the buffer 3 aligns with the connecting post 2 on the slide rail 1, the connecting post 2 will enter along the connecting groove 4 on the buffer 3. The buckle 5 on the side wall of the connecting groove 4 will be compressed and deformed when the connecting post 2 enters. Once the connecting post 2 is fully in the predetermined position, the buckle 5 will spring back due to its own elasticity and press against the surface of the connecting post 2, forming a limiting area 6 together with the connecting groove 4, thereby firmly "locking" the connecting post 2 inside the buffer 3, achieving integrated fixation of the two. This structure enables quick installation without tools; the user only needs to push it in to complete the connection, greatly simplifying the installation operation and improving efficiency.

[0026] In one embodiment: the connecting groove 4 is an arc-shaped inner groove, and a V-shaped groove 7 is provided at the top of the connecting groove 4, which penetrates the upper end surface of the buffer 3.

[0027] In this embodiment, the connecting groove 4 is designed as an arc-shaped inner groove, which makes the fit with the connecting post 2 tighter. The V-shaped groove 7, which is opened at the top of the connecting groove 4 and extends through the upper surface of the buffer 3, has a dual function: on the one hand, the opening shape of the V-shaped groove 7 provides a spacious entrance, further assisting the connecting post 2 in alignment and smooth entry into the connecting groove 4; on the other hand, the opening of the V-shaped groove 7 also provides the necessary space for the subsequent elastic deformation of the undercut 5, and can be used as an external tool to release the undercut 5 from its limiting state when disassembly is required. This structure improves the convenience and alignment of installation, while providing a structural basis and operating path for subsequent convenient and non-destructive disassembly.

[0028] In one embodiment: the two buckles 5 are arranged in a pair, symmetrically on both sides of the V-groove 7, and the free end of the buckle 5 extends into the connecting groove 4.

[0029] In this embodiment, the buckles 5 appear in a pair and are symmetrically arranged on both sides of the V-groove 7. This ensures that when the connecting post 2 enters the connecting groove 4, it will be subjected to a uniform force from the buckles 5 on both sides. The free ends of the buckles 5 extend into the connecting groove 4 and directly contact the connecting post 2. The working principle of this symmetrical arrangement is that when the connecting post 2 is inserted, the buckles 5 are evenly spread open by the post body. When the connecting post 2 passes through the buckles 5, the buckles 5 will spring back inward, thereby achieving a balanced grip or locking of the connecting post 2.

[0030] This symmetrical design provides a balanced and secure locking force, effectively preventing the connecting post 2 from wobbling within the connecting groove 4, improving the stability and reliability of the connection, and facilitating smooth docking operations.

[0031] In one embodiment: the inverted buckles 5 are provided in two pairs, symmetrically distributed in the V-groove 7, and a partition 8 is provided between the two pairs of inverted buckles 5. Correspondingly, the end face of the connecting column 2 is provided with a limiting boss 9, which is snapped onto the partition 8.

[0032] By setting two pairs of inverted clips 5, symmetrically distributed within the V-groove 7, this buffer can be installed regardless of direction, and can be used with either the left or right guide rail simultaneously. Furthermore, a partition 8 is placed between the two pairs of inverted clips 5, and the end face of the connecting post 2 is designed with a matching limiting boss 9. When the connecting post 2 is fully inserted, the limiting boss 9 will precisely engage with the partition 8. This combination of partition and limiting boss further restricts the axial and radial movement of the connecting post 2.

[0033] In one embodiment: at least two connecting columns 2 are provided, which are distributed at intervals on the slide rail 1.

[0034] In this embodiment, when the buffer 3 is simultaneously connected to at least two spaced-ahead connecting posts 2 on the slide rail 1 via one or more internal connecting grooves 4, a multi-point supported fixed structure is formed. This multi-point connection effectively limits the overall swaying or rotation of the buffer 3 relative to the slide rail 1, especially the tilting and twisting along the length of the slide rail. By setting fixed points at different locations, the buffer exhibits better geometric stability on the slide rail. This enhances the overall stability and anti-shaking ability of the buffer installation, ensuring that the buffer maintains the correct posture and stable cushioning effect during drawer movement.

[0035] In one embodiment, the connecting post 2 is fixed to the slide rail 1 by welding. The welding process firmly secures the connecting post 2 to the slide rail 1, making it an integral part of the slide rail 1. Welding creates a bond between metal atoms, providing extremely high connection strength and durability. This allows the connecting post 2 to maintain absolute stability in its position and shape when subjected to various forces during the connection and use of the buffer, providing a solid and reliable foundation for the entire quick-connect mechanism.

[0036] In summary, this utility model provides a quick connection mechanism for drawer slide buffers, the core working principle of which is to construct an efficient, stable and repeatedly disassembled mechanical snap-fit ​​connection system.

[0037] First, at least two connecting posts 2, which are firmly fixed by welding, are pre-installed on the slide rail 1 as a stable base for the buffer connection. The buffer 3 has an arc-shaped concave connecting groove 4 inside, and a V-shaped groove 7 on the top to smoothly guide and accommodate the connecting posts 2.

[0038] The core of the connection lies in the two pairs of inverted buckles 5 precisely arranged on the side wall of the connecting groove 4. They are symmetrically distributed in the V-shaped groove 7, forming a pair structure, with their free ends extending into the connecting groove 4. When the connecting post 2 is pushed into the connecting groove 4, these inverted buckles 5 will automatically deform under force and "hug" or "lock" into the connecting post 2. Once the connecting post 2 is fully in place, the inverted buckles 5 spring back and press against the connecting post 2, forming a limiting zone 6 together with the connecting groove 4, thereby achieving quick, tool-free, integrated fixation of the buffer 3 and the connecting post 2.

[0039] To further enhance the stability and anti-rotation capability of the connection, a partition 8 is provided between the two pairs of inverted buckles 5, which precisely matches the limiting boss 9 on the end face of the connecting column 2. When the connection is completed, the limiting boss 9 is snapped onto the partition 8, effectively restricting the axial movement of the connecting column 2 and ensuring the tightness and long-term reliability of the connection.

[0040] Meanwhile, the V-groove 7 not only assists in guiding the insertion of the connecting post, but also provides a convenient operating interface when disassembly or maintenance is required. By applying external force to temporarily release the buckle 5 from the limiting position on the connecting post 2, the buffer 3 can be easily and non-destructively disassembled and replaced.

[0041] In summary, this utility model provides a solid foundation through the welded connecting column 2, combined with the guidance of the V-groove 7, the automatic snap-fit ​​of the inverted buckle 5, and the auxiliary positioning of the partition 8 and the limiting boss 9, forming an overall connection solution that is easy to install, firmly fixed, and easy to disassemble. This significantly improves the installation efficiency, service life, and user experience of the drawer slide buffer, and therefore can be widely promoted and used.
