Description

Technical Field

[0001] This utility model belongs to the field of furniture innovation technology, specifically a portable, low-cost drawer panel adjustment connector. Background Technology

[0002] With the booming development of the whole-house customization industry, various problems in the installation of customized furniture have gradually emerged. Among them, the difficulty of installing pull-out panels is particularly significant, becoming a key bottleneck affecting the overall installation quality and efficiency.

[0003] First, the precision deviation in panel processing is the primary challenge facing drawer installation. Different batches and materials of panels are prone to subtle but crucial dimensional deviations during cutting and edge banding due to fluctuations in equipment precision and differences in operator techniques. This directly results in inconsistent seam dimensions for each drawer. During installation, workers must not only precisely adjust the horizontal and vertical alignment of the drawers but also ensure alignment with gaps between adjacent drawers or cabinet doors. This multi-dimensional fine-tuning places extremely high demands on the installers' technical proficiency, experience, and even spatial awareness.

[0004] Secondly, the quality and compatibility of the hardware are the core factors determining the installation effect of the drawer front. During long-term use, the hardware such as the drawer slides is prone to slight misalignment due to uneven force and wear. This misalignment is directly transmitted to the drawer front, causing the originally aligned drawer front to gradually become misaligned, resulting in poor opening and closing, abnormal noise, or even jamming. Later maintenance requires disassembly and adjustment, which significantly increases after-sales costs.

[0005] Furthermore, consumers' demand for personalized custom furniture continues to upgrade, with a significant increase in market demand for irregularly shaped drawers (such as curved, beveled, and irregular shapes), while the requirements for product dimensional accuracy are becoming increasingly stringent. This trend undoubtedly exacerbates the difficulty of drawer installation: the non-standard dimensions of irregularly shaped drawers make it more difficult to control board processing errors, significantly reducing the compatibility of traditional hardware. The angle calibration and curvature fitting operations during installation place far higher demands on workers' technical skills and tool precision than with conventional products, further increasing installation time costs and the risk of errors.

[0006] There are two main methods in the current installation process of pull-out panels.

[0007] One method is the traditional one, where a significant portion of the installation work still relies on manual measurement and point marking.

[0008] Another method involves installation using auxiliary tools. The specific process is as follows: The installer first uses a clamp to clamp the outer panel of the drawer box to the drawer surface. Using the thickness of the horizontal part at the top of the clamp, and combined with manual measurement, the gap between the drawer and the drawer is located. Then, the drawer is pulled out of the cabinet. After the drawer is pulled out, the installer screws into the inside of the drawer body to lock the drawer body and the drawer surface together. After the two are locked, the installer removes the clamp.

[0009] Patent CN221604338U discloses a drawer installation aid tool. Based on existing aid tools, it innovatively adds a handle, allowing users to pull the drawer without pulling the tool's moving parts, thus reducing the risk of the tool coming loose when the drawer is pulled out. However, the aid tool is small and easily lost, and its price is not low, making it difficult to promote. Furthermore, it cannot solve the problem of minor misalignment of drawer slides and other hardware due to long-term use, causing the drawer front to jam or collide with adjacent parts.

[0010] The existing technology has the following drawbacks:

[0011] 1. Traditional manual measurement and installation methods often require installers to disassemble and adjust the drawer multiple times. This not only damages the integrity of the back of the drawer but also greatly increases the risk of stripped screws.

[0012] 2. Drawer installation auxiliary tools are difficult to be widely accepted by installers due to their high price and limited size compatibility.

[0013] In addition, both of the above-mentioned mainstream methods require an installer to come to the site to disassemble and reinstall the drawer when the drawer shifts or deforms later, which is both time-consuming and labor-intensive. Utility Model Content

[0014] To address the deficiencies and shortcomings of the existing technology, this utility model provides a portable, low-cost drawer panel adjustment connector that allows for precise positioning of the drawer front panel using intelligent equipment. This enables adjustment of the drawer front panel without disassembly, and even if the drawer front panel gets stuck or collides with adjacent panels during subsequent use, it can be flexibly adjusted automatically. This allows for efficient and precise installation of the drawer front panel, reduces costs, and can be widely promoted as a basic hardware component. It effectively solves the problem of hindered promotion of innovative drawer front panel installation methods.

[0015] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portable, low-cost drawer panel adjustment connector, comprising a connector body and an adapter, wherein the connector body includes:

[0016] A cylindrical insert, wherein the cylindrical insert has a receiving cavity that communicates with the bottom, and the receiving cavity is provided with a sliding guide rail;

[0017] A screw-on positioning cover is provided on the upper end of a cylindrical insert and connected thereto. The screw-on positioning cover has a card box inside and a screw-on positioning rib on the outside.

[0018] A flip cover, one side of which is connected to a screw-on positioning cover, and a sealing strip and a latch are provided at the lower end of the flip cover;

[0019] The adapter has screw holes inside;

[0020] This connector can change the direction of the sliding guide rail by applying force to the screw-on positioning cover, and at the same time, it can slide on the sliding guide rail with appropriate accessories, thereby changing the movable direction of the drawer and adjusting the position of the drawer panel within a certain range.

[0021] Preferably, the screw-on positioning cover and the cylindrical insert are connected as a whole, and the interior has a through-hole receiving cavity, the lower end of which is provided with a sliding guide rail in the shape of a cuboid protrusion.

[0022] Preferably, the diameter of the screw-on positioning cover is 1-2 mm larger than the diameter of the cylindrical insert, and a screw-on positioning rib is provided on its outer side. The inner side adopts a circular recessed design with a recessed depth of about 1-2 mm, and a card box is provided on the outer side of the receiving cavity.

[0023] Preferably, one side of the upper end of the screw-on positioning cover is connected to the flip cover, the lower end of the latch is provided with a quarter-cylindrical protrusion, and the outer side of the latch is provided with a sealing strip of the same material.

[0024] Preferably, the adapter has a T-shaped three-dimensional structure with a through screw hole in the middle and a small arc-shaped protrusion at the bottom.

[0025] A portable, low-cost method for installing a drawer panel adjustment connector, comprising the following steps:

[0026] S1. During the initial installation, fix the T-shaped adapter to the drawer with screws, leaving a 1mm gap to ensure smooth adjustment of the drawer.

[0027] S2. During the adjustment phase, hold and twist the positioning rib to switch the adjustment direction of the sliding guide rail, then gently push the pull surface and use the adapter to slide along the sliding guide rail to complete the fine-tuning of the position.

[0028] S3. After adjustment, tighten the gap left by the screws so that the surface of the adapter is in close contact with the underside of the self-tapping screw head to complete the final fixation. Close the flip cover of the pull-out adjustment connector to complete the final installation. The whole process is easy to operate and does not require the use of complicated or special tools, which greatly improves the efficiency of installation and maintenance.

[0029] A method for using a portable, low-cost drawer panel adjustment connector is as follows:

[0030] Step 1, open the flip cover: Hold the outside of the flip cover with your fingers and apply upward force to disengage the quarter-cylindrical protrusion of the latch from the card holder;

[0031] Step 2: Insert the cylindrical insert into the pre-drilled hole on the outer side panel of the drawer;

[0032] Step 3: Tightening the screws: Move the adapter to approximately the center position, align the self-tapping screw with the screw hole of the adapter, and rotate clockwise until a 1mm gap is left between the self-tapping screw and the adapter, ensuring that the self-tapping screw is fully inserted into the pull surface and is not loose.

[0033] Step 4: Measure the deviation of the sampling position;

[0034] Step 5: Hold the screw-and-tighten positioning rib and rotate the connecting piece to make the horizontal direction of the sliding guide rail consistent with the direction to be adjusted of the pull-out surface;

[0035] Step 6: Gently push the pull tab to adjust its position;

[0036] Step 7: Tighten the screws. Lock the 1mm gap left in Step 3 so that the surface of the adapter is in close contact with the underside of the self-tapping screw head. Close the pull-out adjustment connector and flip it open to complete the pull-out installation.

[0037] Preferably, in step two, the outer side panel of the drawer box is a structure used to connect the drawer front and the drawer box, and its reserved hole needs to match the outer diameter of the cylindrical insert to ensure stable adjustment of the drawer front in the future.

[0038] Preferably, when tightening the screws in step three, the installation position of the pull-out face needs to be initially measured to ensure that the distance to be adjusted later is within the adjustable range;

[0039] Preferably, in step three, the adapter is moved to approximately the center position to ensure the adjustment distance during subsequent adjustment of the pull-out position and to ensure smooth rotation of the connector.

[0040] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0041] 1. A solution is proposed to address the industry pain point of difficulty in controlling the installation accuracy of drawer panels. It breaks through the traditional thinking that drawer panel installation technology only focuses on improving installation tools. The core innovation is shifted to the adjustable performance of the connectors. With the connectors themselves, precise directional adjustment can be achieved directly, which significantly simplifies the installation process and improves the installation accuracy. It has high practical value and promotion prospects.

[0042] 2. Through the precise matching of the innovatively designed T-shaped adapter and the rectangular protruding sliding guide rail inside the receiving cavity, a highly efficient mechanical adjustment mechanism is constructed:

[0043] 3. The small arc-shaped protrusions on the bottom of the adapter can slide smoothly along the sliding guide rail. After the adapter and the drawer are initially fixed with screws, there is no need to disassemble the screws or the drawer during the adjustment process. The position of the drawer can be finely adjusted by simply using this mechanical movement. This avoids the back damage and scratches caused by repeated disassembly of the drawer in the traditional installation method, as well as the risk of stripping the screws caused by repeated tightening. This greatly reduces the error tolerance cost in the installation process.

[0044] 4. The adjustment mechanism eliminates the need for complex manual measurements and experience-based judgment. Workers only need to hold the screw-on positioning rib on the outside of the positioning cover to switch the adjustment direction of the sliding guide rail (horizontal, longitudinal, and diagonal), and then gently push the pull-out surface to complete the position adjustment. The operation process is simplified and standardized. Even non-experienced installers can accurately complete the adjustment after simple training. This effectively lowers the operational threshold for pull-out surface installation, reduces the reliance on workers' technical proficiency and experience, and solves the industry pain point of traditional manual installation requiring excessively high worker technical skills.
