Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and in particular to a cabinet door structure with an upward flip-up design. Background Technology

[0002] In cabinet structure design, in order to ensure that the cabinet door installed at the front open does not occupy the front and bottom space when opened, the cabinet door is usually designed as an upward-opening cabinet door structure.

[0003] However, existing cabinet door structures with upward-opening mechanisms suffer from the following drawbacks due to their flawed design: 1. After the cabinet door is opened, it may easily flip downwards and close itself under gravity, potentially causing injury to the user and compromising safety. 2. The guide connection structure between the cabinet door and the cabinet body is poorly designed, leading to difficulties and jamming when opening the door. 3. The guide connection structure between the cabinet door and the cabinet body has poor strength and is easily damaged during operation.

[0004] Therefore, how to design a cabinet door structure that is simpler and more reasonable in structure, more stable after the cabinet door flips open to make it safer during use, smoother in the flipping and opening process, and has better structural strength has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design a cabinet door structure with a simpler and more reasonable structure, more stable after the cabinet door is flipped open so as to make it safer during use, smoother cabinet door flipping open, and better structural strength.

[0006] To achieve the above objectives, this utility model provides a cabinet door structure with an upward-opening design, comprising a cabinet body with an overall rectangular box structure and an open front side; a cabinet door with an overall rectangular plate structure is provided at the upper part of the cabinet body, and guide rail mechanisms are provided at both ends of the cabinet door and between the door and the cabinet body; the guide rail mechanism is characterized in that: the guide rail mechanism includes a guide member provided on the cabinet body, and a guide groove provided on the guide member, which is arranged along the front-rear direction of the cabinet body, and the rear end of the guide groove is inclined downward; a mating member is provided at the rear end of the cabinet door, and the mating member is correspondingly fitted in the guide groove; a support member is provided at the front end of the guide member, and the support member slides and supports the lower side of the end of the cabinet door; after the cabinet door slides forward along the guide groove, the front side of the mating member can abut against the rear side of the support member to restrict the cabinet door from sliding forward further, and the cabinet door can be flipped downward to cover the open position of the cabinet body.

[0007] Thus, in the aforementioned cabinet door structure with its upward-opening mechanism, the guide groove's rear end is angled downwards, causing the door to tend to slide inwards under gravity when it's open and positioned at the top of the cabinet interior. This makes the door more stable after opening and closing, enhancing safety during use. Secondly, the simplified guide rail mechanism design better prevents the door from detaching from the guide groove, and the smaller contact area between the door and the guide groove reduces friction during opening and closing, resulting in smoother opening and closing and greater ease of use.

[0008] As an optimization, the support member includes a support roller rotatably mounted on the guide member via a mounting shaft, such that the upper side of the support roller abuts against the lower side of the cabinet door end.

[0009] In this way, the support components use support rollers, and the support rollers and cabinet doors have rolling friction, which can reduce friction, reduce wear, and make it easier to use for edge-flipping operations.

[0010] As an optimization, a stop strip is provided at the edge of the lower surface of the cabinet door. The stop strip is arranged along the front and back direction of the cabinet and is positioned at intervals on the inner side of the far end of the support roller.

[0011] In this way, by setting the baffle, the support rollers can make better contact with the cabinet door and form a more stable and reliable support.

[0012] As an optimization, the cabinet door includes a cabinet door panel with a rectangular plate-like structure. Both ends of the cabinet door panel are bent downwards to form side flanges. The lower side of the side flanges bends inwards horizontally to form a supporting flange. The middle part of the inner side of the supporting flange is folded downwards to form the stop strip.

[0013] This allows the baffle strip to be molded as a single piece with the cabinet door, making it easier to process and manufacture.

[0014] Furthermore, the front and rear sides of the cabinet door panel are bent downwards to form a front flange and a rear flange, and the lower sides of the front flange and the rear flange are bent inwards horizontally to form a connecting flange.

[0015] As an optimization, the mating component includes a mating roller mounted on the rear end of the cabinet door via a mounting shaft; and the mating roller is rotatably disposed within the guide groove.

[0016] In this way, the use of matching rollers for the mating components can further reduce friction, making opening and closing smoother.

[0017] As an optimization, a limiting component is installed and fixed at the rear end of the guide component, so that the rear side of the mating roller can be supported against the front side of the limiting component to restrict the cabinet door from sliding further into the cabinet.

[0018] In this way, by setting limiters, the position of the cabinet door can be better restricted, making the design more reasonable.

[0019] As an optimization, a limiting wheel is fixed at the rear end of the guide groove on the guide member and by screws, and the limiting wheel forms the limiting member.

[0020] In this way, by setting a limit wheel to form a limit component, the structural design becomes simpler and more reasonable.

[0021] As an optimization, the guide member includes a guide plate with an overall rectangular structure. The guide plate includes a guide portion with a U-shaped cross-section on the upper side and an inwardly open opening. The guide groove is formed on the guide portion. The lower side of the guide portion is bent downward to form a support flange. The support member is installed at the front end of the support flange. The lower side of the support flange is bent horizontally outward to form a horizontal flange. The outer side of the horizontal flange is bent downward to form an installation flange, and the installation flange is mounted against the inner wall of the box.

[0022] In this way, the structural design of the guide plate is simpler and more reasonable, making it easier to form guide grooves, install and arrange support components, and fix the plate.

[0023] As an optimization, a connecting plate is also provided on the outer side of the rear end of the guide plate. The connecting plate includes a connecting part that is attached and fixed to the outer side of the guide part. The upper side of the connecting part is bent outward and then bent upward to form a fixing part, and the fixing part is installed and fixed on the inner side wall of the box.

[0024] By setting up a connecting plate, the guide plate becomes more stable and reliable after installation, and the structural strength of the entire guide mechanism is also increased.

[0025] Furthermore, a projection weld nut is provided on the connecting part, and the screw for installing the limit wheel is threadedly connected to the projection weld nut after passing through the guide member.

[0026] This makes the limit wheel more stable and reliable after installation.

[0027] In summary, the above-mentioned cabinet door structure with upward-opening mechanism features a simpler and more reasonable structural design, greater stability after the cabinet door is opened for enhanced safety during use, smoother opening and closing, and better structural strength.

[0038] like Figures 1 to 9As shown, a cabinet door structure with a flip-up design includes a cabinet body 1 with a rectangular box-like structure and an open front. A cabinet door 2 with a rectangular plate-like structure is located at the upper part of the cabinet body. Guide rail mechanisms are provided at both ends of the cabinet door and between the door and the cabinet body. The guide rail mechanisms include a guide member 3 on the cabinet body, and a guide groove 4 arranged along the front-to-back direction of the cabinet body, with the rear end of the guide groove inclined downwards. A mating member 5 is located at the rear end of the cabinet door, and the mating member is fitted within the guide groove. A support member 6 is located at the front end of the guide member, and the support member slides and supports the lower side of the cabinet door end. After the cabinet door slides forward along the guide groove, the front side of the mating member abuts against the rear side of the support member to restrict further forward sliding of the cabinet door, allowing the cabinet door to flip downwards and cover the open position of the cabinet body.

[0039] Thus, in the aforementioned cabinet door structure with its upward-opening mechanism, the guide groove's rear end is angled downwards, causing the door to tend to slide inwards under gravity when it's open and positioned at the top of the cabinet interior. This makes the door more stable after opening and closing, enhancing safety during use. Secondly, the simplified guide rail mechanism design better prevents the door from detaching from the guide groove, and the smaller contact area between the door and the guide groove reduces friction during opening and closing, resulting in smoother opening and closing and greater ease of use.

[0040] In this specific embodiment, the support member includes a support roller 7 that is rotatably mounted on the guide member via a mounting shaft, such that the upper side of the support roller abuts against the lower side of the cabinet door end.

[0041] In this way, the support components use support rollers, and the support rollers and cabinet doors have rolling friction, which can reduce friction, reduce wear, and make it easier to use for edge-flipping operations.

[0042] In this specific embodiment, a baffle 8 is provided at the edge of the lower surface of the cabinet door. The baffle is arranged along the front and rear direction of the cabinet and is positioned at intervals on the inner side of the far end of the support roller.

[0043] In this way, by setting the baffle, the support rollers can make better contact with the cabinet door and form a more stable and reliable support.

[0044] In this specific embodiment, the cabinet door includes a cabinet door panel 9 with a rectangular plate-like structure. Both ends of the cabinet door panel are bent downwards to form side flanges 10. The lower side of the side flange is bent inwards horizontally to form a supporting flange 11. The middle part of the inner side of the supporting flange is folded downwards to form the baffle 8.

[0045] This allows the baffle strip to be molded as a single piece with the cabinet door, making it easier to process and manufacture.

[0046] Furthermore, the front and rear sides of the cabinet door panel are bent downwards to form a front flange and a rear flange, and the lower sides of the front flange and the rear flange are bent inwards horizontally to form a connecting flange.

[0047] In this specific embodiment, the mating component includes a mating roller 12 that is rotatably mounted on the rear end of the cabinet door via a mounting shaft; and the mating roller is rotatably disposed within the guide groove.

[0048] In this way, the use of matching rollers for the mating components can further reduce friction, making opening and closing smoother.

[0049] In this specific embodiment, a limiting member 13 is installed and fixed at the rear end of the guide member, so that the rear side of the mating roller can be supported against the front side of the limiting member to restrict the cabinet door from continuing to slide into the cabinet.

[0050] In this way, by setting limiters, the position of the cabinet door can be better restricted, making the design more reasonable.

[0051] In this specific embodiment, a limiting wheel is fixed at the rear end of the guide groove on the guide member by screws, and the limiting wheel forms the limiting member.

[0052] In this way, by setting a limit wheel to form a limit component, the structural design becomes simpler and more reasonable.

[0053] In this specific embodiment, the guide member includes a guide plate 14 with an overall rectangular structure. The guide plate includes a guide portion 15 with a U-shaped cross-section on the upper side and an inwardly open opening. The guide groove is formed on the guide portion. The lower side of the guide portion is bent downward to form a support flange 16. The support member is installed at the front end of the support flange. The lower side of the support flange is bent horizontally outward to form a horizontal flange 17. The outer side of the horizontal flange is bent downward to form an mounting flange 18, and the mounting flange is attached to the inner wall of the box.

[0054] In this way, the structural design of the guide plate is simpler and more reasonable, making it easier to form guide grooves, install and arrange support components, and fix the plate.

[0055] In this specific embodiment, a connecting plate 19 is also provided on the outer side of the rear end of the guide plate. The connecting plate includes a connecting part 20 that is attached and fixed to the outer side of the guide part. The upper side of the connecting part is bent outward and then bent upward to form a fixing part 21, and the fixing part is installed and fixed on the inner side wall of the box.

[0056] By setting up a connecting plate, the guide plate becomes more stable and reliable after installation, and the structural strength of the entire guide mechanism is also increased.

[0057] Furthermore, a projection weld nut 22 is provided on the connecting part, and the screw for installing the limit wheel is threadedly connected to the projection weld nut after passing through the guide member.

[0058] This makes the limit wheel more stable and reliable after installation.
