Description

Technical Field

[0001] This utility model relates to a home hardware accessory, specifically a quick-release structure for a lift-up door opening mechanism. Background Technology

[0002] In home and office furniture, the design of cabinet doors directly affects ease of use and overall aesthetics. Existing upward-opening door mechanisms typically use screws to directly fix the cabinet door to the mechanism. While this provides a secure hold, it has many drawbacks and inconveniences in actual use.

[0003] First, the installation is complex. Traditional screw installation requires manually fixing the cabinet door to the mechanism, demanding not only advanced installation skills but also the use of various tools. For hard-to-reach installation locations, screw installation is time-consuming and labor-intensive, especially when the cabinet door is large or the installation space is limited, further increasing the difficulty of installation.

[0004] Secondly, maintenance is difficult. Since the cabinet doors are directly fixed with screws, routine maintenance such as checking for looseness and replacing parts requires unscrewing each screw one by one. This is not only time-consuming, but frequent disassembly and assembly can also cause wear on the screw holes, reduce the stability of the connection, and affect the long-term performance of the cabinet doors.

[0005] Furthermore, it lacks flexibility. Traditional installation structures do not allow for quick replacement during disassembly and assembly, limiting the modular design of cabinet doors and making it difficult for users to easily adjust or replace them. This deficiency is particularly pronounced in applications requiring frequent disassembly, such as display cabinets or tool cabinets, thus necessitating further improvements. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a quick-release cabinet door structure for a top-opening mechanism that is simple in structure, easy to use, and enables quick installation and disassembly of cabinet doors, thereby optimizing user experience and improving installation efficiency.

[0007] The purpose of this utility model is achieved in the following way: a quick-release cabinet door structure for an upward-opening door mechanism, which includes a base fixed on the cabinet body, the base being connected to a mounting seat through several swing arms, the swing arms swinging relative to the base and the mounting seat to realize the opening and closing of the cabinet door, the mounting seat having a receiving cavity, a connecting seat being detachably installed in the receiving cavity, the connecting seat being installed on the cabinet door, and the cabinet door being detachably installed in the receiving cavity through the connecting seat.

[0008] Furthermore: one side of the connecting seat covers the cabinet door, and the other side protrudes outward to provide a docking seat. The two ends of the docking seat are recessed to provide a first connecting groove and a second connecting groove, and are also provided with a first buckle plate and a second buckle plate. The first connecting groove or the second connecting groove and the first buckle plate or the second buckle plate cooperate with the quick-release component provided in the accommodating cavity to realize the installation and disassembly of the docking seat and the accommodating cavity.

[0009] Furthermore, the quick-release assembly includes a first positioning post disposed within the accommodating cavity and a spring buckle disposed within the accommodating cavity. A first connecting groove or a second connecting groove is inserted into the first positioning post, and the spring buckle is snapped into the first buckle plate or the second buckle plate to fix the mating seat within the accommodating cavity.

[0010] Furthermore: the spring buckle is hinged and installed in the receiving cavity, and a return spring is provided between the spring buckle and the receiving cavity. The return spring pushes the spring buckle to swing towards the first buckle plate or the second buckle plate, so that the buckle groove on the spring buckle is always locked on the first buckle plate or the second buckle plate.

[0011] Furthermore, the spring buckle is hinged and installed in the accommodating cavity via a second positioning post.

[0012] Furthermore, a third positioning post is also provided inside the accommodating cavity, and correspondingly, a third connecting groove is provided on the docking seat. When the docking seat is installed, the third connecting groove is snapped into the third positioning post.

This enables the cabinet door to be quickly installed within the receiving cavity, avoiding the cumbersome process of traditional screw fixing. It significantly simplifies the installation steps, reduces tool dependence, and improves installation efficiency.

[0016] 3. The connecting seat and the receiving cavity are connected by quick-release components, which allows the cabinet door to be quickly disassembled. This makes it easy for users to maintain or replace the cabinet door, reduces the reliance on screws, and extends the service life of the structure.

[0017] 4. The positioning posts, spring clips, and return springs in the quick-release assembly ensure a stable connection between the connector and the receiving cavity. The return spring design of the spring clips maintains a constant locking force on the latch plate, preventing the cabinet door from loosening during use and increasing the structural robustness.

[0018] 5. This utility model adopts a modular design, allowing the cabinet door to be installed and disassembled independently without affecting the stability of the entire opening mechanism. This design facilitates the individual replacement or maintenance of components such as the docking seat and the receiving cavity, making it easier to meet the usage needs of different occasions and improving the product's versatility and adaptability.

[0019] 6. Since the cabinet door does not require repeated disassembly and assembly with screws, this utility model reduces wear on screw holes, lowers structural losses, extends the overall lifespan of the cabinet door and opening mechanism, and greatly reduces maintenance costs.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. A quick-release cabinet door structure for a top-opening door includes a base 1 fixed on the cabinet body. The base 1 is connected to a mounting seat 3 via several swing arms 2. The swing arms 2 swing relative to the base 1 and the mounting seat 3 to open and close the cabinet door 4. The mounting seat 3 is provided with a receiving cavity 5. A connecting seat 6 is detachably installed in the receiving cavity 5. The connecting seat 6 is installed on the cabinet door 4. The cabinet door 4 is detachably installed in the receiving cavity 5 via the connecting seat 6.

[0026] In one embodiment: one side of the connecting seat 6 covers the cabinet door 4, and the other side protrudes outward to provide a docking seat 7. The docking seat 7 has a first connecting groove 71 and a second connecting groove 72 recessed at both ends, and a first snap plate 54 and a second snap plate 55 are also provided. The first connecting groove 71 or the second connecting groove 72 and the first snap plate 54 or the second snap plate 55 cooperate with the quick-release assembly provided in the accommodating cavity 5 to realize the installation and disassembly of the docking seat 7 and the accommodating cavity 5.

[0027] In one embodiment: the quick-release assembly includes a first positioning post 51 disposed in the accommodating cavity 5 and a spring buckle 52 disposed in the accommodating cavity 5. The first connecting groove 71 or the second connecting groove 72 is inserted into the first positioning post 51, and the spring buckle 52 is snapped into the first buckle plate 54 or the second buckle plate 55 to fix the docking seat 7 in the accommodating cavity 5.

[0028] In one embodiment: the spring buckle 52 is hingedly installed in the accommodating cavity 5, and a return spring is provided between the spring buckle 52 and the accommodating cavity 5. The return spring pushes the spring buckle 52 to swing in the direction of the first buckle plate 54 or the second buckle plate 55, so that the buckle groove 56 on the spring buckle 52 is always locked on the first buckle plate 54 or the second buckle plate 55.

[0029] In one embodiment, the spring buckle 52 is hinged to the accommodating cavity 5 via a second positioning post 53.

[0030] In one embodiment: a third positioning post 57 is also provided in the accommodating cavity 5, and correspondingly, a third connecting groove 73 is provided on the docking seat 7. When the docking seat 7 is installed, the third connecting groove 73 is snapped into the third positioning post 57.

[0031] In one embodiment: the third positioning post 57 is located between the first positioning post 51 and the second positioning post 53.

[0032] Working principle: In this case, the base 1 is fixed to the cabinet body and connected to the mounting base 3 via several swing arms 2. The swing arms 2 are hinged to the base 1 and the mounting base 3, and can swing relative to the base and the mounting base, thereby realizing the opening and closing movement of the cabinet door 4. This structure allows the cabinet door to open or close smoothly in an upward tilting manner.

[0033] The mounting base 3 has a receiving cavity 5, which is used to accommodate the connecting base 6. The connecting base 6 is installed in the receiving cavity via a quick-release assembly, and the cabinet door 4 is installed in the receiving cavity via the connecting base, realizing the quick-release structure of the cabinet door.

[0034] One side of the connecting seat 6 covers the cabinet door 4, while the other side has a protruding docking seat 7. The two ends of the docking seat 7 are recessed to form a first connecting groove 71 and a second connecting groove 72. By cooperating with the quick-release assembly in the accommodating cavity, the cabinet door can be quickly installed and removed, simplifying the installation process.

[0035] Specifically, the quick-release assembly includes a first positioning post 51 and a spring clip 52. A first connecting slot 71 or a second connecting slot 72 can be inserted into the first positioning post 51 to achieve initial positioning.

[0036] The spring buckle 52 is hinged within the receiving cavity 5 and pushed by a return spring, constantly swinging towards the first snap plate 54 or the second snap plate 55, thereby engaging the snap groove 56 on the spring buckle 52 with the snap plate. This design ensures that the connecting seat 7 is firmly fixed within the receiving cavity, allowing the cabinet door to be stably connected to the mounting base. When disassembly is required, the connecting seat 6 can be easily removed from the receiving cavity by pushing the spring buckle 52 away from the snap plate, thus enabling quick disassembly of the cabinet door.

[0037] In order to make the connection between the two more secure, a third positioning post 57 is provided in the accommodating cavity 5, and a third connecting groove 73 is provided on the docking seat 7. The cooperation between the third connecting groove and the third positioning post further strengthens the stable connection between the cabinet door and the accommodating cavity.

[0038] It should be noted that the docking seat 7 in this case has a first connecting groove 71 and a second connecting groove 72 recessed at both ends, as well as a first buckle plate 54 and a second buckle plate 55. This makes it possible to install the docking seat without distinguishing between left and right or up and down, and it can be used in any direction.

[0039] Compared with traditional technologies, this invention enables rapid installation and removal of cabinet doors through quick-release components. Traditional screw installation methods often require more tools and steps, while this invention only requires simple push-in and snap-on to achieve installation, significantly improving convenience and installation efficiency.

[0040] Meanwhile, the design of multiple positioning posts and spring-loaded buckles within the accommodating cavity ensures a secure connection between the connector and the cavity. The positioning posts provide multi-point support, while the spring-loaded buckles provide a tight locking force, preventing the cabinet door from loosening or falling off during frequent use, thus improving the safety and durability of the structure.

[0041] In addition, the cabinet door and connecting base are connected via quick-release components, employing a modular design that allows users to easily disassemble the cabinet door for repair or replacement. There's no need to disassemble the entire opening mechanism; only the mating parts of the connecting base and the receiving cavity need to be operated, significantly reducing maintenance costs.

[0042] Furthermore, since it no longer relies on screws for fixing and disassembly, this utility model avoids the wear caused by repeated disassembly and assembly of screw holes, reduces the risk of structural fatigue and loosening, and extends the service life of cabinet doors and the overall door opening mechanism.

[0043] In summary, the working principle of this utility model, through the ingenious design of quick-release components and reset mechanism, solves the problems of cumbersome installation, difficult maintenance, and insufficient stability in the prior art. It has multiple technical advantages such as convenient installation, stable structure, and easy maintenance, and is suitable for wide application in home and office furniture scenarios.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
