Description

Technical Field

[0001] This utility model relates to the field of furniture installation technology, and in particular to a multi-directional connection component for custom cabinets. Background Technology

[0002] With the rapid development of the modern home customization industry, custom cabinets have become widely popular due to their high space utilization and diverse styles. During the assembly of custom cabinets, the connection structure between the cabinet panels directly determines the installation efficiency and the stability of the finished product. Traditional custom cabinet connections mostly use three-in-one connectors or corner brackets with bolts for fixing.

[0003] However, this traditional connection method has significant limitations in practical applications. First, bolted connections require specialized tools for individual tightening. For large custom cabinets, the numerous connection points make the installation process cumbersome and time-consuming, and also demand a certain level of skill from the installers. Second, traditional connection structures typically only allow for unidirectional splicing. When dealing with complex cabinet layouts, multiple connectors often need to be combined, increasing the difficulty of material preparation.

[0004] To address the aforementioned issues, some quick-release connection structures based on the snap-fit ​​principle have emerged on the market. While these structures improve installation speed to some extent, they also introduce new problems. Existing quick-release structures, for ease of disassembly, typically expose their locking components directly to the outside of the connection point. During daily use or transport of the cabinet, these exposed locking components are highly susceptible to accidental contact or impact, leading to accidental unlocking of the connection, causing the cabinet structure to loosen or even disintegrate, posing a significant safety hazard. Therefore, a customized multi-directional cabinet connection component is proposed to solve these problems. Utility Model Content

[0005] In view of the problems existing in the custom cabinet connection components, such as the reliance on bolt fastening leading to cumbersome disassembly and assembly, the single connection direction, and the insufficient structural stability of conventional quick-release structures due to the risk of accidental unlocking caused by exposed locking components, this utility model aims to provide a multi-directional connection component for custom cabinets with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a multi-directional connection assembly for a custom cabinet, comprising: a connecting column, and a connector detachably connected to the side wall of the connecting column; and a quick-release mechanism disposed between the connecting column and the connector. The quick-release mechanism has a fixed frame fixedly connected to the outer wall of the connecting column, and two limiting blocks slidably connected to the inner wall of the fixed frame; the side wall of the connector has a slot adapted to the limiting blocks; the inner wall of the fixed frame is provided with a reset assembly, the reset assembly including a limiting rod fixedly connected to the inner wall of the fixed frame, and two springs sleeved on the outer wall of the limiting rod. Furthermore, a sliding plate is fixedly connected to the side of the limiting block facing the inside of the fixed frame, and both sliding plates are slidably sleeved on the outer wall of the limiting rod; the spring is located on the limiting rod, and one end of the spring abuts against the side wall of the sliding plate, and the other end of the spring abuts against the inner wall of the fixed frame; the spring is used to apply an elastic force to the sliding plate to drive the two limiting blocks to slide in a direction away from the center of the fixed frame and cause part of their structure to extend outside the fixed frame to be engaged in the slot.

[0007] Preferably, the outer walls of the two limiting blocks opposite to each other are provided with multiple parallel anti-slip textures, and the anti-slip textures are used for the operator to apply force to overcome the elastic force of the spring and drive the two limiting blocks to slide towards each other, thereby facilitating manual unlocking and disassembly.

[0008] Preferably, the connecting column is a square tube structure, and each side of the connecting column is fixedly connected to two fixed frames at intervals along the vertical direction to meet the multi-directional splicing requirements and improve the connection stability.

[0009] Preferably, the connecting component further includes a protective mechanism, which is disposed in the included angle space formed after the two adjacent connecting parts are spliced ​​together, and the protective mechanism covers the outside of the fixing frame and the limiting block, for physically isolating the quick-release components.

[0010] Preferably, the protective mechanism includes a protective shell, the inner wall of which abuts against the outer wall of the limiting block, and the outer contour of the protective shell is adapted to the gap shape between the two connecting members to achieve a tight fit and wrapping.

[0011] Preferably, connecting plates are fixedly connected to both sides of the outer wall of the protective shell, and the surface of the connecting plates is provided with mounting through holes for assisting in fixing the protective shell.

[0012] Preferably, the side wall of the connector is provided with a threaded hole, and the protective mechanism further includes a bolt. The connecting plate is fixedly connected to the connector by the bolt passing through the mounting through hole, thereby preventing the protective shell from accidentally falling off.

[0013] Preferably, the limiting rod is horizontally mounted inside the fixed frame, and the sliding plate is located at the opening of the fixed frame. The top and bottom surfaces of the limiting block slide in contact with the inner top and inner bottom walls of the fixed frame, respectively, to ensure the smoothness of the sliding process.

[0014] This utility model has the following beneficial effects: 1. This utility model solves the problem of cumbersome disassembly and inefficiency caused by the reliance on bolt fastening in the existing custom cabinet connection structure by setting a quick-release mechanism including a spring-driven limiting block on the outer wall of the connecting column, and cooperating with the slot opened on the connector. It achieves the technical effect of quick, multi-directional and stable splicing of the connecting column and connector without the need for complicated tools, and significantly improves the assembly efficiency and convenience of the custom cabinet.

[0015] 2. This utility model solves the problem of loosening or falling off of conventional quick-release structures due to accidental contact caused by exposed locking components. It adds a protective mechanism between adjacent connecting parts, uses a protective shell to physically wrap and cover the limiting block of the quick-release mechanism, and locks the protective shell on the connecting parts with connecting plates and bolts. This achieves the technical effect of effectively preventing misoperation and enhancing the safety and stability of the connection nodes, while also beautifying the appearance of the cabinet.

[0016] 3.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Reference Figures 1 to 6 This utility model provides a multi-directional connection component for custom cabinets, which aims to solve the structural defects of existing custom cabinet connection structures that rely on bolt fastening, resulting in cumbersome disassembly and assembly, a single connection direction, and insufficient structural stability due to the risk of accidental unlocking caused by exposed locking components in conventional quick-release structures.

[0022] A multi-directional connection component for a custom cabinet includes a connecting column 1 and a connector 2 detachably connected to the side wall of the connecting column 1 to form the cabinet panel. A quick-release mechanism 3 is provided between the connecting column 1 and the connector 2 to enable quick locking and separation of the two. The connecting column 1 mainly serves as the core hub for assembling the custom cabinet to bear the connecting forces from all directions, while the connector 2 serves as the main component of the cabinet to enclose the storage space.

[0023] The connecting column 1 has a square tubular structure to accommodate multi-directional splicing requirements. Each side of the connecting column 1 has two fixed frames 32 arranged at intervals along the vertical direction. By setting two fixed frames 32 on the same side, the torsional resistance and overall stability of the connecting column 1 after it is connected to the connector 2 can be effectively improved. The fixed frame 32 serves as the basic mounting base for the quick-release mechanism 3. Its cross-section is U-shaped or rectangular, and the opening of the fixed frame 32 faces the side where the connector 2 is located, so as to facilitate the installation and movement extension of the internal components.

[0024] The connector 2 is usually a plate-shaped structure. A recessed groove 31 is provided on the side wall end face of the connector 2. The shape and size of the groove 31 are adapted to the limiting block 33 in the quick release mechanism 3, and are used to accommodate and lock the limiting block 33, thereby limiting the horizontal displacement of the connector 2 relative to the connecting column 1.

[0025] The quick-release mechanism 3 includes a fixed frame 32 fixedly connected to the outer wall of the connecting post 1, and two symmetrically distributed limiting blocks 33 slidably connected to the inner wall of the fixed frame 32. These two limiting blocks 33 can perform linear sliding movements relative to or opposite to each other within the fixed frame 32 to achieve the action state of extension locking or retraction unlocking. With this arrangement, in the unlocked state, the outer wall of the connecting post 1 and the fixed frame 32 thereon form a male head structure waiting to be connected, while the connecting piece 2 and its slot 31 form a female head structure. The two work together to achieve multi-directional splicing.

[0026] A reset assembly 35 is provided inside the fixed frame 32. The reset assembly 35 mainly includes a limiting rod 351 fixedly connected to the inner wall of the fixed frame 32, and two springs 352 sleeved on the outer wall of the limiting rod 351. The limiting rod 351 is horizontally mounted at the center of the fixed frame 32, serving as a guide and support to ensure that subsequent moving parts move smoothly along a predetermined trajectory. The springs 352 serve as a power source, responsible for storing and releasing elastic potential energy to drive the locking action.

[0027] Each limiting block 33 has a sliding plate 34 fixedly connected to one side facing the inside of the fixed frame 32. The two sliding plates 34 are located on both sides of the length of the limiting rod 351, and are slidably sleeved on the outer wall of the limiting rod 351. This structural design makes the limiting block 33 and the sliding plate 34 form an integral motion unit, which can perform axial reciprocating linear motion along the limiting rod 351, effectively preventing jamming or deflection during the movement.

[0028] Spring 352 is located on limiting rod 351 and between sliding plate 34 and inner wall of fixed frame 32. Specifically, one end of spring 352 directly abuts against side wall of sliding plate 34, and the other end abuts against inner wall or central partition of fixed frame 32. Through this abutment relationship, spring 352 always applies a pushing force to sliding plate 34 away from center of fixed frame 32. Spring 352 drives two limiting blocks 33 to slide outward in opposite directions until part of the limiting block 33 extends outside fixed frame 32. When connector 2 is installed in place, slot 31 aligns with limiting block 33, and spring 352 releases its elastic force to push limiting block 33 into slot 31 to complete automatic locking; when disassembling, the operator needs to overcome the resistance of spring 352 to retract limiting block 33 inward, and sliding plate 34 compresses spring 352 to make room for disassembly.

[0029] In a preferred embodiment, the connecting assembly also includes a protective mechanism 4. The protective mechanism 4 is disposed within the included angle space formed by the splicing of two adjacent connecting pieces 2, and covers the outside of the fixing frame 32 and the limiting block 33, thereby completely enclosing the core locking component inside. The protective mechanism 4 includes a protective shell 41, which has an L-shaped or V-shaped structure, and its length is greater than or equal to the length of the fixing frame 32. In the installed state, the inner wall of the protective shell 41 directly abuts against the outer wall of the limiting block 33, preventing external objects from touching the limiting block 33 through physical blocking. The outer contour of the protective shell 41 matches the shape of the gap between the two connecting pieces 2, allowing the protective shell 41 to smoothly transition with the surface of the connecting piece 2 after installation.

[0030] In a preferred embodiment, connecting plates 42 are fixedly connected to both sides of the outer wall of the protective shell 41. The surface of the connecting plate 42 is provided with mounting through holes, and the side wall of the connector 2 is pre-drilled with threaded holes. The protective mechanism 4 passes through the mounting through holes on the connecting plate 42 with bolts 43 and screws into the threaded holes of the connector 2, thereby firmly locking the protective shell 41 between the two connectors 2 to achieve double protection.

[0031] In a preferred embodiment, when the spring 352 is in a compressed state or in a naturally extended state, the outer surface of the limiting block 33 remains parallel or coplanar with the side wall of the connecting post 1. This design ensures that the limiting block 33 will not protrude excessively and cause bumps when the connecting member 2 is not connected, and also facilitates the initial positioning and alignment of the connecting member 2.

[0032] The implementation principle of this application embodiment is as follows: a multi-directional connection component for a custom cabinet constructs a full-dimensional splicing system around the connecting column 1. The connecting column 1 serves as the core hub for splicing the custom cabinet. Multiple fixed frames 32 are uniformly fixed on its outer wall. The quick-release mechanism 3 and the connecting parts 2 achieve multi-directional detachable connection. A protective mechanism 4 is assembled between adjacent connecting parts 2 to protect the key components of the quick-release mechanism 3.

[0033] The quick-release mechanism 3 is assembled between the connecting column 1 and the connecting piece 2 to enable quick assembly and disassembly of the two, adapting to the multi-directional splicing requirements of customized cabinets. Multiple fixing frames 32 are evenly fixed on the outer wall of the connecting column 1, and two fixing frames 32 are fixed on the same side of the connecting column 1 to improve connection stability. Multiple slots 31 that fit the limiting blocks 33 are provided on the connecting piece 2. Two limiting blocks 33 are slidably fitted on the inner wall of each fixing frame 32. A sliding plate 34 is fixed on one side of the limiting block 33. The limiting rod 351 included in the reset assembly 35 is fixed on the inner wall of the fixing frame 32. The two sliding plates 34 are slidably sleeved on the outer wall of the limiting rod 351 to ensure sliding orientation. Two springs 352 are sleeved on the outside of the limiting rod 351. The side closer to each other is fixed on the sliding plate 34, and the side farther away is fixed on the inner wall of the fixing frame 32. The side of the two limiting blocks 33 far away is provided with anti-slip texture for users to grip and apply force.

[0034] In the initial state, all the springs 352 in the fixed frame 32 are in a naturally relaxed state. Pushing the sliding plate 34 causes the limiting block 33 to partially extend out of the fixed frame 32. The connecting column 1 and the connecting parts 2 in each direction are in a separated and waiting-to-connect state, and there is no relative movement between the components.

[0035] When multi-directional connection is required, according to the splicing requirements of the customized cabinet, align the connector 2 with the installation position of the fixing frame 32 in the corresponding direction of the connecting column 1 and push it. The connecting column 1 presses against the two limiting blocks 33 in the fixing frame 32, causing the limiting blocks 33 to slide along the inner wall of the fixing frame 32 in a direction away from each other. The limiting blocks 33 drive the sliding plate 34 to simultaneously compress the spring 352, and the spring 352 contracts to store elastic potential energy. When the connector 2 and the connecting column 1 are fully fitted, the slot 31 on the connector 2 is precisely aligned with the limiting block 33 in the fixing frame 32. The spring 352 releases elastic potential energy, pushing the sliding plate 34 to drive the limiting block 33 to engage in the slot 31, forming a mechanical lock, restricting the relative movement of the connecting column 1 and the connector 2, and achieving a stable splicing. This solves the problem of traditional customized cabinet connections requiring bolts 43 for fastening, cumbersome disassembly and assembly, and a single direction, achieving the effect of multi-directional and rapid splicing. If splicing in other directions is required, repeat the above operation to lock the corresponding connector 2 and the connecting column 1. When disassembly is required, the user holds the anti-slip texture on the far side of the two limiting blocks 33 and pulls the two limiting blocks 33 in the far direction. The limiting blocks 33 drive the sliding plate 34 to slide along the outer wall of the limiting rod 351 to both sides, and simultaneously squeeze the spring 352 to retract it until the limiting blocks 33 are completely disengaged from the slot 31, and the locking constraint is released. At this time, pulling the connector 2 can separate it from the connecting column 1. After releasing the limiting blocks 33, the spring 352 releases its elastic potential energy, pushing the sliding plate 34 and the limiting blocks 33 back to the initial extended state. The quick-release mechanism 3 corresponding to the fixed frame 32 returns to the ready-to-connect state, which can meet the re-splicing requirements of the connecting column 1 in any direction.

[0036] The protective mechanism 4 is assembled between the two connecting parts 2 and is used to protect the limit block 33 of the quick-release mechanism 3 after the connecting parts 2 and the connecting column 1 are assembled, so as to prevent accidental contact that would cause the connection to unlock. The protective shell 41 is the main body of the protection and is adapted to the gap between the two connecting parts 2. Multiple connecting plates 42 are evenly fixed on the outer wall of the protective shell 41. The connecting plates 42 are fixedly connected to the connecting parts 2 by bolts 43.

[0037] In its initial state, the protective mechanism 4 is in the state of waiting to be installed. The connector 2 has not yet been spliced ​​with the connecting column 1. The protective shell 41, the connecting plate 42 and the bolt 43 are all independent components and have not been assembled with other structures.

[0038] After the connector 2 completes multi-directional splicing with the connector post 1 via the quick-release mechanism 3, and the limiting block 33 snaps into the slot 31 to achieve a stable connection, to prevent accidental contact with the limiting block 33 that could cause the connection to loosen, the operator places the protective shell 41 in the gap between two adjacent connectors 2, aligning the inner wall of the protective shell 41 with the outer side of the limiting block 33, ensuring that the protective shell 41 completely covers the limiting block 33, forming a physical isolation; then, the position of the protective shell 41 is adjusted so that the multiple connecting plates 42 on the outer wall are precisely aligned with the mounting holes of the pre-set bolts 43 on the connector 2, and the bolts 43 are passed through the holes of the connecting plates 42 and screwed into the mounting holes of the connector 2 until the bolts 43 are completely tightened. The connecting plate 42 securely fixes the protective shell 41 between the two connecting parts 2. The protective shell 41 fits tightly against the outer wall of the connecting part 2, completely enclosing the limiting block 33. This solves the problem of the limiting block 33 of the quick-release mechanism 3 being exposed and easily accidentally touched, achieving the effect of preventing accidental touch and ensuring connection stability. If the quick-release mechanism 3 needs to be maintained in the future, simply use a tool to unscrew the bolt 43, remove the connecting plate 42 and the protective shell 41, and the limiting block 33 can be exposed for operation. After maintenance, the protective shell 41 is placed back between the two connecting parts 2 and fixed and reset by the connecting plate 42 and the bolt 43. The protective mechanism 4 returns to the protective state and continues to protect the limiting block 33 from accidental touch.
