Description

Technical Field

[0001] This invention belongs to the field of modular cabinets, and more specifically, it relates to a freely modular cabinet that can be quickly locked and unlocked. Background Technology

[0002] Modular cabinets are furniture systems that integrate multiple independent cabinets through a specific design. While retaining traditional storage functions, their modular combination allows for flexible adaptation to different spatial layouts and personalized needs. This design stems from the pursuit of space utilization efficiency and functional versatility. Users can freely configure and adjust the cabinet combinations according to actual usage needs and space dimensions to achieve efficient space integration.

[0003] Currently, most modular cabinets in existing technologies use metal connectors (such as threaded rods and bolts) for fixing and assembling the cabinets. After the cabinets are assembled, if the layout needs to be readjusted or the combination method changed, the connectors must be loosened and disassembled one by one, and the cabinets must be completely disassembled and reassembled, resulting in a cumbersome and inefficient reassembly process. Furthermore, current modular cabinets have relatively simple assembly methods, mostly assembling sequentially in a vertical plane, leading to poor stability and functionality. Summary of the Invention

[0004] In view of the problems in related technologies, the present invention proposes a freely combinable cabinet that can be quickly locked and unlocked, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a freely combinable cabinet that can be quickly locked and unlocked, comprising cabinet panels, a connecting mechanism, and latches. Multiple cabinet panels can be connected and assembled into a cabinet unit via the connecting mechanism. The upper and lower ends of the cabinet unit are respectively provided with latches and slots that can engage with the latches. The latches are provided with sliding and retractable locking tongues. Adjacent cabinet units can be movably inserted and positioned via the connecting mechanism, and the locking tongue in one cabinet unit can slide and engage in the slot in another adjacent cabinet unit.

[0006] Furthermore, the cabinet panel includes a top panel, side panels, and a bottom panel.

[0007] Furthermore, the connecting mechanism includes cabinet legs, the sides of which are provided with vertically distributed side plate slots and bottom plate slots, and the top of which is provided with insertion holes; The base plate has insertion parts at each of its four corners that correspond to the base plate slots, and the top plate has connecting posts at each of its four corners that can be inserted into the insertion holes.

[0008] Furthermore, the bottom end of the cabinet leg is provided with a support foot that can be inserted into the socket.

[0009] Furthermore, a reinforcing support plate slot is provided on one side of the upper end of the cabinet leg, and a reinforcing support plate is inserted into the reinforcing support plate slot.

[0010] Furthermore, the top plate includes a long top plate and a short top plate, the length of which is an integer multiple of the length of the short top plate, and the bottom plate includes a long bottom plate and a short bottom plate corresponding to the long top plate and the short top plate, respectively; The reinforcing support plate includes a long support plate and a short support plate corresponding to the long top plate and the short top plate, respectively. The top surface of the long support plate is provided with a groove, and a crossbeam is installed in the groove. The top surface of both ends of the crossbeam is provided with two insertion holes.

[0011] Furthermore, the latch includes a main body, one end of which is fixedly installed on the inner side of the side plate, and the other end of which is fixedly installed on the bottom surface of the base plate. The latch is slidably installed on the lower end of the main body, and the side plate or connecting mechanism is provided with a slot that can be slidably engaged with the latch.

[0012] Furthermore, an unlocking part is slidably installed inside the main body, a drive groove is provided on the top surface of the lock tongue, a pin is inserted into the lower end of the main body through a pin hole, a lever is rotatably installed on the pin, one end of the lever is inserted into the drive groove, and the other end of the lever rests on the top surface of the lower end of the unlocking part.

[0013] Furthermore, the bottom plate has a clearance groove on its side corresponding to the main body, and the side plate has a through hole located above the latch; A limiting shaft is fixedly installed at the rear end of the locking tongue, and the limiting shaft is slidably inserted into the main body.

[0014] Furthermore, a positioning part one is fixedly installed on the upper end of the main body, and a positioning part two is fixedly installed on the lower end of the main body. Both the positioning part one and the positioning part two are provided with positioning holes.

[0015] The present invention has the following beneficial effects: 1. In this invention, multiple cabinet panels can be connected and assembled into a cabinet unit through a connecting mechanism, and adjacent cabinet units are locked together by a sliding and unlockable latch. When the combination cabinet needs to be disassembled and assembled, simply slide the latch to unlock it, thereby releasing the lock between two adjacent cabinet units and achieving quick unlocking between the cabinet units. Correspondingly, during assembly, two cabinet units are initially inserted and positioned through the connecting structure, and then the two cabinet units are locked and limited by the latch, thereby achieving rapid assembly and installation of the combination cabinet. By setting long top plates, short top plates, long bottom plates, short bottom plates, long support plates, and short support plates, cabinet units of different lengths can be combined and installed, improving the diversity and functionality of the combination cabinet. For example, cabinet units can be gradually stacked upwards for assembly, or they can be assembled vertically in the horizontal direction. When assembling vertically, the stability of the cabinet connection and installation can be improved by staggering the long and short cabinet units of the upper and lower layers.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0022] Please see Figures 1-13 As shown, the present invention is a freely combinable cabinet that can be quickly locked and unlocked, including cabinet panels 1, connecting mechanisms 2 and latches 3. Multiple cabinet panels 1 can be connected and assembled into a cabinet unit through the connecting mechanism 2. The upper and lower ends of the cabinet unit are respectively provided with latches 3 and slots that can engage with the latches 3. The latches 3 are provided with sliding and telescopic locking tongues 39. Adjacent cabinet units can be movably inserted and positioned through the connecting mechanism 2, and the locking tongues 39 in the previous cabinet unit can slide and engage in the slots in the adjacent cabinet unit.

[0023] When the modular cabinet needs to be disassembled and reassembled, the locking tongue 39 is pulled out from the slot in the adjacent cabinet unit, thereby releasing the lock between the two adjacent cabinet units and realizing quick unlocking between the cabinet units. Correspondingly, during assembly, the two cabinet units are initially inserted and positioned by the connecting mechanism 2, and then the locking tongue 39 in the latch 3 is slid into the slot in the adjacent cabinet unit, which can lock and limit the two cabinet units, thereby realizing the quick assembly and installation of the modular cabinet.

[0024] Specifically, the cabinet panel 1 includes a top panel 11, side panels 12 and bottom panel 13, and the connecting mechanism 2 includes cabinet legs 21. The sides of the cabinet legs 21 are provided with vertically distributed side panel slots 25 and bottom panel slots 27, and the top of the cabinet legs 21 is provided with insertion holes 23. The four corners of the bottom panel 13 are provided with insertion parts 15 corresponding to the bottom panel slots 27, and the four corners of the bottom surface of the top panel 11 are provided with connecting posts 16 that can be inserted into the insertion holes 23. When assembling the cabinet unit, the four cabinet legs 21 are inserted into the four plug-in parts 15 at the four corners of the base plate 13 through the base plate slot 27. Then, the side plates 12 are installed between the cabinet legs 21 on both sides through the side plate slot 25. Finally, the top plate 11 is connected to the plug-in holes 23 at the top of the cabinet legs 21 through the connecting posts 16 at the four corners of the bottom surface. In this way, the four cabinet legs 21, two side plates 12, one base plate 13 and one top plate 11 can be assembled to form a cabinet unit.

[0025] Specifically, the bottom of the cabinet leg 21 is provided with a support foot 24 that can be inserted into the socket 23. When it is necessary to assemble a multi-layer combination cabinet, except for the top cabinet unit, the other cabinet units below do not need to be assembled with the top plate 11. The upper and lower adjacent cabinet legs 21 are connected by the socket 23 and the support foot 24, so that the cabinet unit components can be initially assembled and limited by the insertion and cooperation of the socket 23 and the support foot 24.

[0026] Specifically, a reinforcing support plate slot 26 is provided on one side of the upper end of the cabinet leg 21. A reinforcing support plate 22 is inserted into the reinforcing support plate slot 26, which can improve the stability of the cabinet unit assembly.

[0027] Specifically, the top plate 11 includes a long top plate and a short top plate, the length of which is an integer multiple of the length of the short top plate; the bottom plate 13 includes a long bottom plate and a short bottom plate corresponding to the long top plate and the short top plate, respectively; the reinforcing support plate 22 includes a long support plate and a short support plate corresponding to the long top plate and the short top plate, respectively; the top surface of the long support plate is provided with a groove, and a crossbeam 28 is installed in the groove; the top surface of both ends of the crossbeam 28 is provided with two insertion holes 23. By using a combination of long top plates, short top plates, long bottom plates, short bottom plates, long support plates, and short support plates, cabinet units of different lengths can be assembled, increasing the versatility of the modular cabinets. For example, cabinet units can be stacked upwards or assembled vertically in the horizontal direction. Furthermore, during assembly, by staggering the long and short cabinet units on the upper and lower layers, the stability of the cabinet connection and installation can be improved.

[0028] Specifically, the latch 3 includes a main body 31, one end of which is fixedly installed on the inner side of the side plate 12, and the other end of which is fixedly installed on the bottom surface of the base plate 13. The latch 39 is slidably installed on the lower end of the main body 31, and the side plate 12 or the connecting mechanism 2 is provided with a slot that can slide and engage with the latch 39. The unlocking part 32 is slidably installed inside the main body 31. The top surface of the latch 39 is provided with a drive groove 310. A pin 38 is inserted into the lower end of the main body 31 through a pin hole 36. A lever 37 is rotatably installed on the pin 38. One end of the lever 37 is inserted into the drive groove 310, and the other end of the lever 37 overlaps the top surface of the lower end of the unlocking part 32. The main body 31, the unlocking part 32, and the lever 37 are all L-shaped structures. When unlocking, the unlocking part 32 is pushed upward along the main body 31 with a finger, causing the unlocking part 32 to drive one end of the lever 37 to move upward. At this time, the lever 37 rotates around the pin 38 as the fulcrum, causing the lower end of the lever 37 (the end inserted into the drive groove 310) to rotate inward and move inward. During the inward rotation, it abuts against the inner wall of the drive groove 310, thereby retracting the latch 39 inward, so that the latch 39 can be pulled out of the slot and the locking between adjacent cabinet units is released.

[0029] Specifically, the side of the base plate 13 is provided with a relief groove 17 corresponding to the main body 31. By providing the relief groove 17, the lower end of the main body 31 can extend to the bottom surface of the base plate 13 through the relief groove 17, so as to facilitate the locking connection between the latch 3 and the cabinet unit below. The side plate 12 is provided with a through hole 14 located above the latch 3. When unlocking, a hand can be inserted into the cabinet through the through hole 14 to push the unlocking part 32 upward, making the unlocking operation more convenient. A limiting shaft 311 is fixedly installed on the rear end of the locking tongue 39. The limiting shaft 311 is slidably inserted into the main body 31. The limiting shaft 311 slides and limits the locking tongue 39, making the locking tongue 39 more stable. A return spring is fitted on the limiting shaft 311 and abuts against the back of the locking tongue 39. A return spring is installed in the main body 31 and abuts against the top surface of the unlocking part 32. When the unlocking is completed and the unlocking part 32 is released, the two return springs can drive the locking tongue 39 and the unlocking part 32 to move and reset respectively.

[0030] Specifically, a positioning part 1 33 is fixedly installed on the upper end of the main body 31, and a positioning part 2 35 is fixedly installed on the lower end of the main body 31. Positioning parts 1 33 and 2 35 are both provided with positioning holes 34, which can be used to lock the positioning parts 1 33 and 2 35 onto the side plate 12 and the bottom plate 13 respectively by passing screws through the positioning holes 34. This not only improves the stability of the installation of the latch 3, but also locks the connection between the side plate 12 and the bottom plate 13 through the latch 3, thereby improving the firmness of the connection between the side plate 12 and the bottom plate 13.
