Description

Technical Field

[0001] This utility model relates to the field of tools, specifically to an assembly structure for a wall cabinet. Background Technology

[0002] In modern interior spaces such as kitchens, bathrooms, studies, and living rooms, wall cabinets (especially hanging cabinets and wall-mounted cabinets) are widely used because they save floor space and improve storage efficiency. These cabinets are usually connected to the wall through a specific assembly structure, and the reliability, flexibility, and ease of maintenance of their installation are crucial.

[0003] Currently, the mainstream technical solutions for installing wall cabinets have the following limitations:

[0004] 1. Fixed bolt / nail installation: This is the most basic method. Fixed points (expansion bolts, nails, etc.) are pre-set on the cabinet back panel and the wall, and then fixed by hooks or connectors.

[0005] Main drawbacks: The cabinet's installation position is completely fixed and cannot be adjusted. If a change in layout is required (e.g., replacing appliances with larger ones or adjusting the countertop layout), the cabinet must be disassembled, the original wall fixing points must be destroyed, and new holes must be drilled for repositioning. This process is cumbersome, causes irreversible damage to the wall, and the accuracy of repositioning is difficult to guarantee, affecting aesthetics and overall harmony.

[0006] 2. Inadequacies of anti-overturning bracing:

[0007] Wall cabinets (especially deep wall cabinets) will generate an outward overturning moment when loaded. Traditional installation methods mainly rely on the back suspension point to resist vertical loads, which has limited effectiveness in resisting this overturning force. Commonly used auxiliary support solutions (such as L-shaped metal angle irons and floor-standing support legs) can enhance stability, but they have significant drawbacks:

[0008] Aesthetically unappealing: Exposed support components disrupt the overall harmony between the cabinet and the wall.

[0009] Space occupied: The supporting legs occupy the ground underneath.

[0010] Inconvenient to adjust: The installation position of the support components is usually fixed, making it difficult to flexibly match the changes in the cabinet position.

[0011] Summary of the core issues of existing wall cabinet assembly structures:

[0012] Rigid positioning: The cabinet cannot be continuously and steplessly adjusted on the wall, which limits the optimization of space utilization and the flexibility of later layout changes.

[0013] Unreliable positioning and locking: The lack of a simple and secure arbitrary position locking function makes the cabinet prone to displacement, resulting in poor stability and potential safety hazards.

[0014] Lack of anti-tipping stability: Insufficient resistance to the overturning moment of deep cabinets. Existing external support leg solutions sacrifice aesthetics, occupy space and have poor flexibility.

[0015] Adjustments can be destructive: Relocation often requires re-drilling, damaging the wall surface and making the process cumbersome.

[0016] Therefore, in the field of wall cabinet assembly technology, there is an urgent need for an innovative structural solution that can simultaneously address the aforementioned key requirements. Utility Model Content

[0017] The purpose of this utility model is to provide an assembly structure for a wall cabinet that allows the cabinet to be freely positioned and securely locked in the selected location. It provides dual restriction and locking functions, a concealed support mechanism, effectively enhances the cabinet's anti-overturning stability, reduces the extra space occupied by the support structure and the problem of insufficient aesthetics, and achieves simple installation, flexible adjustment and minimal damage to the wall surface, increasing the overall strength, reliability and aesthetics of the structure.

[0018] To achieve the above objectives, the present invention adopts the following technical solution:

[0019] An assembly structure for a wall cabinet includes a cabinet body, a guide rail, a bracket, a hanger, and a limiting structure. The guide rail is mounted on the wall, and the hanger is connected to the back of the cabinet body via the bracket. The guide rail has a positioning groove along its length for inserting the hanger. The limiting structure is located between the hanger and the positioning groove. The limiting structure includes a limiting component and a reinforcing component. The hanger can be inserted and automatically engaged in any position of the positioning groove by the limiting component, and the reinforcing component is moved to reinforce the connection between the hanger and the positioning groove.

[0020] Compared with existing technologies, the assembly structure of the wall cabinet using the above-mentioned technical solution has the following advantages:

[0021] The wall cabinet assembly structure of this utility model utilizes a long, narrow positioning groove structure provided by the guide rail, along with a double-locking function provided by the hanging components and limiting structure, to achieve the requirement of free positioning of the cabinet and secure locking in the selected position. Specifically, during direct upward and downward movement, the limiting component can automatically engage for initial fixation. This initial fixation scheme is not a loose connection structure; it already ensures stable assembly of the cabinet when not subjected to significant force. Combined with the adjustment operation of the reinforcing components, a double-limiting function can be achieved, preventing the cabinet from moving freely and ensuring stable assembly of the cabinet in the selected position. Furthermore, the guide rail, located between the cabinet and the wall, provides a concealed support mechanism.

[0022] Preferably, the limiting component includes a limiting strip, a limiting groove, a support part, and a support groove. The hanger consists of a base and a middle insert. The base is connected to the bracket, and the insert is located below the base. Two limiting strips and two support parts are provided. The two limiting strips are symmetrically arranged on both sides below the base. The limiting strips do not contact the insert, and a limiting groove is formed between the limiting strips and the insert. The two support parts are symmetrically arranged on two side walls of the positioning groove. The support parts have an "L" shape, and a support groove is formed between the support parts and the inner side wall of the positioning groove. When the hanger is placed into the guide rail, the insert is located between the two support parts, and the limiting strip is inserted into the support groove, with a portion of the support part entering the limiting groove. The gap between the two support parts is used to limit and fix the insert (middle part of the hanger), the support groove is used to limit and fix the limiting strip, and the limiting strip is used to limit and fix the portion of the support part. This achieves multi-point support and limiting effects inside the guide rail, ensuring the stability of the initial fixed connection.

[0023] Preferably, the reinforcing component includes a locking button, a movable plate, a movable slot, and an inlet / outlet slot. The locking button is rotatably mounted on the insert block. The movable plate has a cuboid structure and is connected to the locking button. The insert block has a movable slot near its lower end to accommodate the movable plate. There are two inlet / outlet slots, each located on one side of the movable slot. The movable slot communicates with the interior of the positioning slot via the inlet / outlet slots, which are located near the end of the movable plate. During the synchronous rotation of the movable plate by rotating the locking button, both ends of the movable plate pass through the inlet / outlet slots and enter the positioning slot until it is laterally locked in the positioning slot, thus restricting the overall movement of the hanger and preventing it from moving freely.

[0024] Preferably, the end of the movable plate is arc-shaped on the side closest to the inlet / outlet groove direction. This arc-shaped end face design avoids obstruction when the movable plate detaches from or enters the inlet / outlet groove, increasing operational convenience and efficiency.

[0025] Preferably, the hanger and the bracket are detachably connected. The connection between the bracket and the hanger can be an integrated connection to increase structural strength and overall stability, or it can be a detachable connection (such as a stable assembly connection using screws or bolts). The purpose of a detachable connection is to allow for the individual replacement or maintenance of individual components later. In this case, considering the issue of individual component maintenance affected by the usage scenario, a detachable connection structure is adopted.

[0026] Preferably, the bracket consists of a connecting piece and a connecting seat, which are fixedly connected. The connecting piece is mounted on the back side of the cabinet, and its area is not less than half the area of ​​the back side of the cabinet. The connecting piece is connected to the base, and both the connecting piece and the base are provided with control grooves that expose the locking buttons. The large support area provided by the connecting piece on the back side of the cabinet effectively enhances the cabinet's anti-tipping stability.

[0027] Preferably, a wall panel is provided between the guide rail and the bracket, and the wall panel is connected to the wall and / or the guide rail. The above-mentioned mating piece in conjunction with the wall panel structure can further and effectively enhance the overturning stability of the cabinet and increase the structural strength in the assembled state.

[0028] Preferably, the wall panel is connected to the guide rail via a fixing plate, and the fixing plate is assembled and connected to the wall using existing expansion screws. This method of connecting the wall panel to the guide rail and then to the wall provides a strong support position on the underside of the guide rail, further increasing structural stability and strength. Furthermore, the connection between the guide rail and the wall allows for a fully stable assembly of the integrated structure containing the guide rail and the fixing plate with the wall.

[0029] Preferably, it also includes a cushioning support, which can be connected between the fixed plate and the wall. This effectively provides cushioning and shock absorption during the placement of large wall cabinets and in daily use. Attached Figure Description

[0038] The present invention will now be further described with reference to the accompanying drawings.

[0039] like Figures 1 to 7 The assembly structure of the wall cabinet shown includes cabinet body 1, guide rail 2, bracket 3, hanging parts 4, and limiting structure.

[0040] The guide rail 2 is mounted on the wall surface 0, and the hanging part 4 is connected to the back side of the cabinet 1 through the bracket 3. The guide rail 2 has a positioning groove 20 for the hanging part 4 to be inserted along its length. A limiting structure is set between the hanging part 4 and the positioning groove 20. The limiting structure includes a limiting component 5 and a reinforcing component 6. The hanging part 4 can be inserted and automatically engaged in any position of the positioning groove 20 by the limiting component 5, which drives the reinforcing component 6 to move to reinforce the connection between the hanging part 4 and the positioning groove 20.

[0041] The limiting component 5 includes a limiting strip 50, a limiting groove 51, a support part 52, and a support groove 53.

[0042] The pendant 4 consists of a base 40 and a middle insert 41. The base 40 is connected to the bracket 3. The insert 41 is located below the base 40. There are two limiting strips 50 and two support parts 52. The two limiting strips 50 are symmetrically arranged on the lower sides of the base 40. The limiting strips 50 do not contact the insert 41, and a limiting groove 51 is formed between the limiting strips 50 and the insert 41. The two support parts 52 are symmetrically arranged on the two side walls of the positioning groove 20. The support parts 52 have an "L" shape structure, and a support groove 53 is formed between the support parts 52 and the inner side wall of the positioning groove 20. When the pendant 4 is inserted into the guide rail 2, the insert 41 is located between the two support parts 52, and the limiting strips 50 are inserted into the support groove 53. Part of the support parts 52 enters the limiting groove 51.

[0043] The reinforcement component 6 includes a locking button 60, a movable plate 61, a movable groove 62, and an inlet / outlet groove 63.

[0044] The locking button 60 is rotatably mounted on the insert block 41. The movable plate 61 has a cuboid structure and is connected to the locking button 60. The insert block 41 has a movable groove 62 near its lower end to accommodate the movable plate 61. There are two inlet and outlet grooves 63, which are respectively located on both sides of the movable groove 62. The movable groove 62 is connected to the interior of the positioning groove 20 through the inlet and outlet grooves 63. The inlet and outlet grooves 63 are located near the end of the movable plate 61 of the movable groove 62.

[0045] To avoid obstruction when the movable plate 61 detaches from or enters the inlet / outlet slot 63, the end of the movable plate 61 near the inlet / outlet slot 63 is arc-shaped. Furthermore, to further enhance the reinforcement effect, both ends of the movable plate 61 are provided with a thin anti-slip layer (made of a thin layer of silicone or a thin layer of rubber).

[0046] The connection between bracket 3 and hanger 4 can be an integrated connection to increase structural strength and overall stability, or it can be a detachable connection (such as a stable assembly connection using screws or bolts). The purpose of a detachable connection is to allow for the individual replacement or maintenance of a single component later.

[0047] The bracket 3 is divided into a docking piece 30 and a docking seat 31. The docking piece 30 and the docking seat 31 are fixedly connected (in this embodiment, a multi-point screw fixing connection is used). The docking piece 30 is assembled on the back side of the cabinet 1. The area of ​​the docking piece 30 is not less than 1 / 2 of the area of ​​the back side of the cabinet 1. The docking piece 30 is connected to the base 40. Both the docking piece 30 and the base 40 are provided with a control groove 32 for the lock button 60 to be exposed.

[0048] To prevent the lock button 60 structure from obstructing external objects, the end of the lock button 60 in this embodiment has an internal hexagonal structure.

[0049] In addition, to provide sufficient support between the cabinet 1 and the wall 0, a wall panel 7 is provided between the guide rail 2 and the bracket 3, and the wall panel 7 is connected to the wall 0 and / or the guide rail 2.

[0050] In this embodiment, considering structural stability and structural strength, the wall panel 7 is connected to the guide rail 2 and the wall surface 0. That is, the wall panel 7 is connected to the guide rail 2 through the fixing piece 8, and the fixing piece 8 is assembled and connected to the wall surface 0 through existing expansion screws.

[0051] Furthermore, to further increase the stability of the connection with the wall 0, the guide rail 2 body is also connected to the wall 0 through existing expansion screws, that is, the guide rail 2 and the fixing plate 8 both have a supporting connection structure with the wall 0.

[0052] In addition, to provide cushioning and shock absorption when the large wall-mounted cabinet is placed, a cushioning support 9 is also included. The cushioning support 9 can be connected between the fixing plate 8 and the wall surface 0, that is, the expansion screw is connected to the wall surface 0 by passing through the fixing plate 8 and the cushioning support 9.

[0053] During use, the back panel of cabinet 1 is connected to bracket 3, bracket 3 is connected to hanger 4, guide rail 2 is fixed to wall 0, and wall panel 7 provides stable support between guide rail 2 and bracket 3. During installation, cabinet 1 is lifted up and then lowered. The insert 41 of hanger 4 enters the positioning groove 20 of guide rail 2. During this process, the placement position of cabinet 1 is determined before lowering. After lowering, insert 41 is located between two support parts 52, limit strip 50 is inserted into support groove 53, and part of support part 52 is inserted into limit groove 51. Guide rail 2, wall panel 7 and fixing piece 8 jointly support hanger 4, bracket 3 and cabinet 1. At this time, hanger 4 is initially locked in positioning groove 20.

[0054] Next, using a wrench, pass it through the control slots 32 of the docking seat 31 and the base 40 in sequence, and insert it into the locking button 60 to rotate it. This causes the movable plate 61 to rotate synchronously. The part of the movable plate 61 with the arc-shaped end face moves towards the inlet / outlet slot 63, disengaging from the inlet / outlet slot 63 and locking into the two inner side walls of the positioning slot 20. That is, the movable plate 61 is horizontally locked into the positioning slot 20 of the guide rail 2, achieving a double locking purpose with the initial locking, and the cabinet 1 is safely fixed. If disassembly is required, rotate the locking button 60 in the opposite direction and lift the cabinet 1 to achieve disassembly and separation.

[0055] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
