Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically a cabinet concealed connector. Background Technology
[0002] Cabinet concealed connectors are structural accessories used in furniture assembly. They achieve seamless connection of cabinet panels through a concealed design, resulting in a clean and aesthetically pleasing appearance. These connectors are typically made of metal or high-strength plastic and are installed inside the panels through methods such as pre-embedding, clips, or screws, ensuring structural stability while avoiding exposed nail holes or seams.
[0003] Common concealed connectors include three-in-one connectors, concealed hinges, and concealed drawer slides, which are widely used in custom wardrobes, cabinets, and other panel furniture, balancing practicality and aesthetics.
[0004] According to a cabinet concealed connector disclosed in Chinese Patent Publication No. CN214465390U, the expansion part of the first component is fixedly connected to the second component, which has a hollow columnar structure. The second component abuts against the baffle, so that the first component and the second component are tightly combined into a connector. The first component is tightly screwed onto the side panel of the cabinet by the tightening part, and several annular guide teeth on the second component are tightly pressed into the holes in the cabinet enclosure, so that the cabinet connector is hidden inside the side panel and enclosure of the cabinet.
[0005] However, the aforementioned devices, combined with existing concealed connectors, require the entire connector to be pulled out when the cabinet needs to be disassembled after installation. This operation can easily lead to obvious holes on the side of the cabinet panel, and may cause the cabinet panel to break at the connection point under stress concentration, putting the entire cabinet at risk of being scrapped. Due to the irreversible installation method and destructive disassembly characteristics, this type of connection structure is actually a disposable consumable, which cannot be recycled and increases maintenance costs.
[0006] Therefore, we propose a cabinet concealed connector to solve the problems mentioned above. Utility Model Content
[0007] The purpose of this utility model is to provide a cabinet concealed connector to solve the problem mentioned in the background art that the connector cannot be repeatedly disassembled and installed.
[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0009] A cabinet concealed connector includes a horizontal plate and a vertical plate. A male component is provided inside the horizontal plate, and a female component is provided inside the vertical plate. A slot for easy connection is provided on one side of the female component, and a locking groove for fixing is provided inside the female component. A plug rod adapted to the slot is provided at one end of the male component. A locking mechanism for engaging with the locking groove is provided on the surface of the plug rod, and a magnetic component for disengaging the locking mechanism from the locking groove is provided on the surface of the locking mechanism.
[0010] Both the female and male parts have threaded grooves on their surfaces that connect to the vertical and horizontal plates.
[0011] The female component has an internal hexagonal groove on one side to facilitate threading the female component into the vertical plate.
[0012] One side of the male component is fixedly connected to an external hexagonal head, which facilitates threading the male component into the horizontal plate. One end of the external hexagonal head is fixedly connected to the insertion rod.
[0013] The engaging mechanism includes a rack slidably connected inside the insert rod, the surface of the rack being fixedly connected to a magnetic component, a rotatable gear meshing on the surface of the rack, the gear being rotatably connected inside the insert rod, and an engaging rod that engages with the engaging groove being fixedly connected to one end of the gear.
[0014] One end of the rack is fixedly connected to a spring that applies pressure to the rack, and the other end of the spring is fixedly connected inside the insert rod.
[0015] The magnetic components on the surface of the rack can be driven by external magnetic force to move along a preset path.
[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0017] When it is necessary to disassemble the male and female components, the external magnetic force adheres tightly to the surface of the horizontal plate, causing the magnetic component on the surface of the rack to move along a preset path. At the same time, the magnetic component drives the rack to move, compressing the rack spring. The rack then drives the gear to rotate, causing the gear to rotate and rotate the locking rod inside the insertion rod. This causes the locking rod to disengage from the locking groove, allowing the insertion rod to slide out of the female component, thus separating the male and female components. This allows the horizontal and vertical plates of the cabinet to be disassembled, facilitating the disassembly of the concealed connectors without damaging them. The concealed connectors can be reused. Attached Figure Description

[0024] 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.
[0025] Please see Figure 1-5 This utility model provides a technical solution:
[0026] like Figures 1-5 As shown, a cabinet concealed connector includes a horizontal plate 1 and a vertical plate 2. A male component 3 is provided inside the horizontal plate 1, and a female component 4 is provided inside the vertical plate 2. A slot 5 for easy connection is provided on one side of the female component 4, and a locking groove 6 for fixing is provided inside the female component 4. A plug rod 7 that is adapted to the slot 5 is provided at one end of the male component 3. A locking mechanism for engaging with the locking groove 6 is provided on the surface of the plug rod 7. A magnetic component 8 that can disengage the locking mechanism from the locking groove 6 is provided on the surface of the locking mechanism.
[0027] like Figures 1-5 As shown, male component 3 is inserted into the horizontal plate 1, and female component 4 is inserted into the vertical plate 2. Then, male component 3 drives the insertion rod 7 to insert into the slot 5 inside the female component 4. The locking mechanism inside the insertion rod 7 opens and then locks the locking groove 6 inside the female component 4, thus fixing male component 3 and female component 4 and fixing the horizontal plate 1 and vertical plate 2 of the cabinet. When it is necessary to disassemble male component 3 and female component 4, the external magnetic force is pressed tightly against the surface of the horizontal plate 1, causing the external magnetic force to drive the magnetic component 8 on the surface of the locking mechanism to move along a preset path, causing the locking mechanism locking end to close, allowing the insertion rod 7 to slide out of the female component 4, thus separating male component 3 and female component 4 and disassembling the horizontal plate 1 and vertical plate 2 of the cabinet. This facilitates the disassembly of the concealed connector without damaging it, and the concealed connector can be reused.
[0028] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, both the female part 4 and the male part 3 have threaded grooves 9 on their surfaces for connecting with the vertical plate 2 and the horizontal plate 1. The female part 4 has an internal hexagonal groove 10 on one side to facilitate threading the female part 4 into the vertical plate 2. The male part 3 has an external hexagonal groove 11 on one side to facilitate threading the male part 3 into the horizontal plate 1. One end of the external hexagonal groove 11 is fixedly connected to the insertion rod 7.
[0029] The threaded grooves 9 on the surfaces of the female part 4 and the male part 3 allow for better connection between the female part 4 and the vertical plate 2 and the horizontal plate 1. Meanwhile, the internal hexagonal groove 10 on one side of the female part 4 facilitates the use of a wrench to thread the female part 4 into the interior of the vertical plate 2, and the external hexagonal groove 11 on one side of the male part 3 facilitates the use of a wrench to thread the male part 3 into the interior of the horizontal plate 1.
[0030] Furthermore, such as Figures 1-5 As shown, the engaging mechanism includes a rack 12 slidably connected inside the insert rod 7. The surface of the rack 12 is fixedly connected to a magnetic component 8. A rotatable gear 13 meshes with the surface of the rack 12. The gear 13 is rotatably connected inside the insert rod 7. One end of the gear 13 is fixedly connected to an engaging rod 14 that engages with the engaging groove 6. One end of the rack 12 is fixedly connected to a spring 15 that applies pressure to the rack 12. One end of the spring 15 is fixedly connected inside the insert rod 7. The magnetic component 8 on the surface of the rack 12 can be driven by external magnetic force to move along a preset path.
[0031] When the insert rod 7 is inserted into the slot 5 on one side of the female part 4, the spring 15 drives the rack 12 to slide inside the insert rod 7, causing the rack 12 to drive the gear 13 to rotate. The gear 13 then drives the engaging rod 14 to flip inside the insert rod 7, causing the engaging rod 14 to engage in the engaging groove 6, thus completing the connection between the insert rod 7 and the female part 4. When it is necessary to disassemble the male part 3 and the female part 4, the external magnetic force adheres tightly to the surface of the horizontal plate 1, causing the external magnetic force to drive the magnetic component 8 on the surface of the rack 12 to move along a preset path. At the same time, the magnetic component 8 drives the rack 12 to move, causing the rack 12 to compress the spring 15. The rack 12 drives the gear 13 to rotate, causing the gear 13 to rotate the locking rod 14 inside the insertion rod 7, so that the locking rod 14 disengages from the locking groove 6, allowing the insertion rod 7 to slide out of the female component 4, completing the separation of the male component 3 and the female component 4, and allowing the horizontal plate 1 and vertical plate 2 of the cabinet to be disassembled, which facilitates the disassembly of the hidden connector without damaging it. The hidden connector can be reused.
[0032] Furthermore, the end of the engaging rod 14 is provided with a guide slope, and the entrance of the engaging groove 6 is provided with a flared structure that cooperates with the guide slope, forming a self-guiding engagement during insertion.
[0033] The surface of the horizontal plate 1 is provided with a magnetic operation marking area corresponding to the position of the magnetic component 8. The magnetic operation marking area adopts a recessed marking structure and is filled with fluorescent material.
[0034] The circumferential surface of the insertion rod 7 is provided with an annular limiting protrusion, and the inner wall of the slot 5 of the female part 4 is provided with an elastic sealing ring that is interference-fitted with it. When the limiting protrusion contacts the sealing ring, tactile feedback is generated.
[0035] In the above solution, the guide bevel at the end of the locking rod and the flared structure at the entrance of the locking groove form a self-guiding fit. During the insertion of the rod, the position is automatically corrected by the bevel contact, guiding the locking rod to slide accurately into the locking groove, reducing installation difficulty and improving connection reliability. The recessed magnetic operation marking area on the surface of the horizontal plate clearly indicates the position of the magnetic component in a dark environment with fluorescent material, making it easy for users to quickly locate and apply external magnetic force to unlock the locking mechanism, simplifying disassembly operations. The annular limiting protrusion of the rod and the elastic sealing ring in the female part slot are interference-fitted. When the rod is inserted into place, tactile feedback indicates that the installation is complete. At the same time, the sealing ring can buffer vibration and enhance connection sealing, extending service life.
[0036] The working principle of this type of concealed cabinet connector is as follows:
[0037] When it is necessary to disassemble male component 3 and female component 4, the external magnetic force adheres tightly to the surface of the horizontal plate 1, causing the magnetic force to drive the magnetic component 8 on the surface of the rack 12 to move along a preset path. At the same time, the magnetic component 8 drives the rack 12 to move, causing the rack 12 to compress the spring 15. The rack 12 drives the gear 13 to rotate, causing the gear 13 to drive the locking rod 14 to flip inside the insertion rod 7, causing the locking rod 14 to disengage from the locking groove 6, allowing the insertion rod 7 to slide out of the female component 4, thus completing the separation of male component 3 and female component 4. This allows the horizontal plate 1 and vertical plate 2 of the cabinet to be disassembled, facilitating the disassembly of the concealed connector without damaging it. The concealed connector can be reused.
[0038] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
