Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to a custom cabinet corner reinforcement connection component. Background Technology

[0002] In modern home decoration, custom cabinets are widely favored by consumers because they can make full use of space and meet personalized aesthetic needs. In the production and assembly process of custom cabinets, the splicing quality between cabinet panels, especially the corner connections, directly determines the structural strength and service life of the entire cabinet.

[0003] However, existing corner connection methods for custom cabinets typically use eccentric wheels or ordinary corner screws for fixing. These traditional connection technologies have significant shortcomings in long-term use. Since the cabinet panels are mostly made of wood, they are prone to slight expansion or contraction due to environmental humidity and temperature. In addition, the vibration from opening and closing the doors during daily use often causes the threaded engagement to loosen or the eccentric wheel structure to fail. Once the connection becomes loose, it will not only cause the cabinet to shake and deform, but in severe cases, it may even cause the connector to fall off, posing a safety hazard of cabinet collapse. Furthermore, some existing reinforcement corner brackets are mostly fixed angles, lacking adjustment capabilities when dealing with irregularly shaped cabinets or special angle splicing, making installation extremely inconvenient.

[0004] Therefore, this utility model proposes a customized corner reinforcement connection component to address the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a customized cabinet corner reinforcement connection component, which aims to improve the problems of insufficient connection stability of some customized cabinet corner connectors in the prior art, easy loosening and falling off due to environmental changes or vibrations due to relying solely on friction for fixation, and the rigid structure being difficult to adapt to the splicing requirements of different angle boards and poor installation flexibility.

[0006] This utility model provides a customized cabinet corner reinforcement connection component, including: a fixing pin and an installation and fixing mechanism. The installation and fixing mechanism includes an installation ring disposed on the side wall of the fixing pin, a reinforcing piece rotatably connected to the side wall of the fixing pin, a connecting bolt passing through the reinforcing piece and inserted into the installation ring, a limiting piece fixed to one end of the connecting bolt, and a spring-loaded component disposed inside the connecting bolt.

[0007] The connecting bolt has an internal cavity and an opening at one end away from the limiting piece. The spring assembly includes a return spring, a washer, and a sliding head. The return spring is located at the bottom of the cavity, the sliding head is slidably located at the opening, and the washer is slidably fitted within the cavity and located between the return spring and the sliding head.

[0008] Furthermore, the two ends of the return spring abut against the bottom surface of the inner wall of the accommodating cavity and the surface of the gasket, respectively. The return spring abuts against the sliding head through the gasket, causing part of its structure to extend out of the opening, thereby achieving self-locking and reinforcement of the connecting component through elastic force.

[0009] Preferably, the inner wall of the opening of the connecting bolt is provided with a radially recessed stop, and the bottom of the sliding head is provided with a limiting flange that cooperates with the stop. The outer diameter of the limiting flange is larger than the aperture of the opening to restrict the sliding head from disengaging and ensure the structural integrity of the connecting assembly under stress.

[0010] Preferably, the end of the sliding head extending outside the connecting bolt has a hemispherical or arc-shaped smooth curved surface structure, which is used to reduce frictional resistance when passing through an object, making the connection process smoother.

[0011] Preferably, the mounting ring has a U-shaped or circular structure, and the inner diameter of the mounting ring is clearance-fitted with the outer diameter of the connecting bolt. When the connecting bolt is inserted into the mounting ring, the sliding head elastically abuts against the inner wall or edge of the mounting ring under the rebound action of the return spring, further enhancing the fastening force of the connection.

[0012] Preferably, the limiting piece has a disc-shaped structure, the outer diameter of the limiting piece is larger than the diameter of the through hole on the reinforcing piece for the connecting bolt to pass through, and a cross-shaped or straight driving groove is provided on the end face of the limiting piece away from the connecting bolt, so that the user can use tools to perform installation or disassembly operations.

[0013] Preferably, one end of the reinforcing plate is provided with a rotating sleeve, and the fixing pin passes through the rotating sleeve. The reinforcing plate is a long strip plate with a flat surface on its inner side for fitting the plate to ensure stable contact with the plate.

[0014] Preferably, the relative rotation angle between the fixing pin and the reinforcing piece is between 90 degrees and 180 degrees, which can flexibly adapt to various board splicing scenarios such as right angles or planes.

[0015] Preferably, the reinforcing plate is made of a tough material that can be bent according to the angle of the fixing pin, thereby better fitting the corners of cabinets of different shapes.

[0016] Preferably, the outer diameter of the gasket is adapted to the inner diameter of the accommodating cavity, and the return spring is compressed and stores energy when the sliding head is pressed and retracted, ensuring a continuous and stable locking force.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a spring-loaded component consisting of a return spring, a washer, and a sliding head inside the connecting bolt, utilizes the elastic restoring force of the return spring to push the sliding head to maintain an outward pushing tendency. When the connecting bolt is inserted into the mounting ring, the sliding head automatically pops out and forms a strong elastic abutment or snap-fit ​​with the inner wall of the mounting ring. This solves the problem in the prior art where cabinet connecting parts rely solely on friction for fixation and are prone to loosening and falling off due to vibration or thermal expansion and contraction of the wood. It achieves the technical effect of the connecting component having a self-locking function and greatly improving the stability and safety of the cabinet corner splicing.

[0018] 2. This utility model, by setting a reinforcing plate that is rotatably connected to the fixed pin, and in combination with the toughness of the reinforcing plate itself and the rotating sleeve structure, realizes the free adjustment of the reinforcing plate relative to the fixed pin within the range of 90 degrees to 180 degrees. It solves the problem that existing rigid connectors are difficult to adapt to non-standard angles or varied splicing scenarios, and achieves the technical effect of strong versatility of the connecting components, flexible installation and adaptability to different furniture design needs.

[0019] 3. This utility model solves the problems of traditional connectors being prone to over-screwing and damaging the plate during installation, as well as the problem of insufficient friction on the connection surface causing plate displacement, by setting a large-diameter limiting piece at the tail end of the connecting bolt and setting an anti-slip texture on the inner side of the reinforcing piece. It achieves the technical effect of further protecting the integrity of the plate and locking the splicing position through the dual means of mechanical limiting and surface pressure.

[0022] 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.

[0023] Example: Reference Figures 1 to 3 This utility model provides a customized cabinet corner reinforcement connection component, which aims to solve the structural defects in the prior art where the corner splicing connection of customized cabinets is not stable enough and is difficult to adapt to the splicing requirements of different angle boards, resulting in easy loosening and falling off after long-term use.

[0024] like Figure 1 and Figure 2 As shown, it includes a fixing pin 1 and an installation and fixing mechanism 2 disposed on the side wall of the fixing pin 1. The fixing pin 1 serves as a rotating base for the connecting component and is used to insert into the pre-drilled hole on the side of the first piece of composite wood board. The installation and fixing mechanism 2 is used to connect and reinforce the second piece of wood board in conjunction with the reinforcing plate 23. The two work together to complete the angle adjustment and locking fixation between the boards. The main body of the fixing pin 1 is cylindrical and can rotate in the hole on the side of the floor or cabinet to adjust the installation angle. The installation and fixing mechanism 2 includes an installation ring 21, a connecting bolt 22, a reinforcing plate 23, and a limiting plate 24. The components are connected in a stable manner through a specific mechanical structure.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The mounting ring 21 is fixedly connected to the axial end side wall of the fixing pin 1. It has a U-shaped or circular structure and its inner diameter is designed to allow the connecting bolt 22 to be inserted and form a clearance fit. The function of the mounting ring 21 is to serve as the locking force point for the connecting bolt 22. One end of the reinforcing plate 23 is integrally formed or fixedly provided with a rotating sleeve. The rotating sleeve is sleeved on the outer wall of the fixing pin 1 to realize the rotational connection between the reinforcing plate 23 and the fixing pin 1, so that the reinforcing plate 23 can rotate around the fixing pin 1. Its relative rotation angle range covers 90 degrees to 180 degrees to adapt to the splicing scenarios of right angle or flat plate.

[0026] The reinforcing plate 23 is designed as a long strip plate with a certain degree of toughness, which can be bent appropriately according to the angle of the fixing pin 1. The inner side of the reinforcing plate 23 that is used to fit the plate is provided with anti-slip texture or anti-slip pad to increase the friction between the contact surface and the plate. The side of the reinforcing plate 23 away from the rotating sleeve has a through hole for the connecting bolt 22 to pass through. The connecting bolt 22 is the main through-connector, and its main body is cylindrical. The connecting bolt 22 passes through the through hole on the reinforcing plate 23 and extends into the interior of the mounting ring 21. The tail end of the connecting bolt 22 is fixedly connected to the limiting plate 24. The limiting plate 24 has a disc-shaped structure and its outer diameter is larger than the diameter of the through hole on the reinforcing plate 23. So when the connecting bolt 22 is inserted into place, it abuts against the outer surface of the reinforcing plate 23 to prevent the connecting bolt 22 from being over-inserted. At the same time, the end face of the limiting plate 24 away from the connecting bolt 22 has a cross-shaped or straight drive groove, which makes it easy for the user to use tools to screw or push.

[0027] Meanwhile, the cylindrical body of the connecting bolt 22 has an axially extending accommodating cavity inside, and the end of the connecting bolt 22 away from the limiting piece 24 has an opening. The inner wall of the opening has a radially recessed baffle. The baffle is used to axially limit the internal components and prevent the internal parts from coming out. The outer wall of the connecting bolt 22 is smooth so that it can smoothly pass through the reinforcing piece 23 and the mounting ring 21, ensuring the structural strength of the connecting assembly when subjected to shear force.

[0028] It is also provided with a spring assembly 25 located inside the connecting bolt 22. The spring assembly 25 includes a return spring 251, a washer 252 and a sliding head 253. The components work together to provide dynamic locking force.

[0029] Key references Figure 3 The return spring 251 is located at the bottom of the cavity inside the connecting bolt 22. One end of the return spring 251 abuts against the bottom surface of the inner wall of the cavity, and the other end extends outward. The washer 252 is slidably fitted in the cavity and is located between the return spring 251 and the sliding head 253. The outer diameter of the washer 252 is precisely matched with the inner diameter of the cavity to ensure that it slides smoothly in the cavity without tilting. The other end of the return spring 251 abuts against the surface of the washer 252, and the elastic force is evenly transmitted to the sliding head 253 through the washer 252.

[0030] The sliding head 253 is slidably positioned at the opening at the front end of the connecting bolt 22. Its bottom is provided with a limiting flange that cooperates with the radially inward-shrinking stop at the opening. The outer diameter of the limiting flange is larger than the diameter of the opening, thus restricting the sliding head 253 from completely disengaging from the connecting bolt 22. However, under the continuous pushing action of the return spring 251, part of the structure of the sliding head 253 remains protruding outside the connecting bolt 22. The end of the sliding head 253 protruding outside the connecting bolt 22 is designed as a smooth curved surface structure in the shape of a hemisphere or arc. When the connecting bolt 22 is inserted into the mounting ring 21, this arc surface can convert the axial thrust into a radial component, allowing the sliding head 253 to retract smoothly. After the connecting bolt 22 is inserted into place, the sliding head 253 pops out under the rebound action of the return spring 251 and forms an elastic abutment or snap-fit ​​with the inner wall or edge of the mounting ring 21, thereby achieving axial limiting and reinforcement of the connecting bolt 22.

[0031] The implementation principle of this application embodiment is as follows: When the user needs to reinforce the splicing of the boards during the assembly of the customized cabinet, the fixing pin 1 is first inserted into the reserved hole on the side of the first board, and the angle of the fixing pin 1 is adjusted within the range of 90 degrees to 180 degrees according to the splicing angle requirements. Then, the reinforcing plate 23 is tightly attached to the inner surface of the second board, so that the anti-slip texture or anti-slip pad on the reinforcing plate 23 can play a role in increasing friction to prevent the board from sliding.

[0032] Next, the connecting bolt 22 is aligned with the through hole on the reinforcing plate 23, passes through the reinforcing plate 23 and the wooden board in sequence, and is inserted into the mounting ring 21. As the front end of the connecting bolt 22 contacts and enters the mounting ring 21, the hemispherical or arc-shaped curved surface at the front end of the sliding head 253 is squeezed at the entrance of the mounting ring 21. The sliding head 253 overcomes the elastic force of the return spring 251 and retracts into the accommodating cavity inside the connecting bolt 22. The gasket 252 slides inward and compresses the return spring 251 to store energy.

[0033] When the connecting bolt 22 is fully inserted into the mounting ring 21 until the limiting piece 24 abuts against the outside of the reinforcing piece 23, the sliding head 253 passes through the specific mating area of ​​the mounting ring 21 or reaches the other edge. At this time, the return spring 251 releases the accumulated elastic potential energy, pushing the pad 252 and the sliding head 253 outward, so that the sliding head 253 forms a tight elastic abutment with the inner wall or edge of the mounting ring 21, thereby locking the position of the connecting bolt 22 and preventing it from accidentally coming out due to vibration or external force. Through the cooperation of the mounting and fixing mechanism 2 and the spring component 25, a high-strength reinforced connection at the joint of the wooden board is achieved.
