Description

Technical Field

[0001] This utility model relates to the field of cabinet door technology, and in particular to a silent cabinet door. Background Technology

[0002] Cabinet doors are an indispensable component of cabinet systems, primarily used to enclose the interior space of cabinets, protecting stored items, preventing dust and moisture, and enhancing the home environment. Common cabinet doors are connected to the cabinet body via hinges and open and close using sliding, hinged, or folding mechanisms. With the development of home design, users' functional demands for cabinet doors are increasing, such as noise reduction, ease of operation, and structural stability. However, current cabinet door designs still have significant shortcomings, particularly in noise control during opening and closing and the ability to stop the door at will, which urgently require improvement.

[0003] Traditional cabinet doors typically rely on simple hinge structures or dampers to close, but these solutions have the following problems:

[0004] 1. Inability to stop at will: Existing cabinet doors are difficult to stop at any angle, requiring users to manually adjust the door position, which is inconvenient. For example, when the cabinet door is opened to a certain angle, if there is no effective support structure, the door will automatically close or fully open due to gravity, affecting the user experience.

[0005] 2. Loud closing noise: When the cabinet door closes, the lack of a buffer structure between the door and the cabinet body easily produces an impact sound. Especially in magnetic or mechanical locking devices, the direct contact between metal parts further amplifies the noise, affecting the tranquility of the home environment. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a silent cabinet door, which overcomes the shortcomings of the existing technology and effectively solves the problems of not being able to stop at will and the loud noise when closing.

The freely adjustable stop rod assembly includes a sleeve hinged to the top of the inner wall of one side of the cabinet, and a push rod hinged to the outer wall of one side of the cabinet door. A piston is fixedly connected to the outer wall of one end of the push rod, and the push rod is slidably connected to the inner wall of the sleeve. A first buffer pad is adhered to the bottom of one outer wall of the cabinet, and a second buffer pad is adhered to the bottom of one outer wall of the cabinet door, with the first buffer pad located to one side of the second buffer pad.

[0009] Preferably, the arbitrarily stop support rod assembly further includes a sealing ring and a vent hole, wherein the sealing ring is installed on the outer wall of the piston, and the sealing ring and the sleeve are interference-fitted.

[0010] Preferably, the bottom of one outer wall of the cabinet is fixedly connected with symmetrically distributed magnetic positioning sleeves, and the bottom of one outer wall of the cabinet door is fixedly connected with symmetrically distributed magnetic positioning balls, the magnetic positioning balls being tightly attached to the inner wall of the magnetic positioning sleeves.

[0011] Preferably, the first buffer pad is located between two magnetic positioning balls, and the second buffer pad is located between two magnetic positioning sleeves.

[0012] Preferably, sealing strips are adhered to the outer walls on both sides and the bottom of the cabinet door, and the sealing strips are attached to the connection between the cabinet and the cabinet door.

[0013] Preferably, a handle is welded to the outer wall of the other side of the cabinet door.

[0014] Preferably, an observation window is affixed to the inner wall of the cabinet door.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The silent cabinet door of this design, through the sliding cooperation between the push rod and the inner wall of the sleeve and the air pressure adjustment of the piston, allows the cabinet door to be suspended at any angle, reducing the difficulty of operation;

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-6 Example 1: A silent cabinet door includes a cabinet 1. A cabinet door 2 is hinged to one outer wall of the cabinet 1. A free-stop support rod assembly 3 is hinged between the cabinet 1 and the cabinet door 2. The free-stop support rod assembly 3 includes a sleeve 31 hinged to the top of the inner wall of one side of the cabinet 1 and a push rod 32 hinged to the outer wall of one side of the cabinet door 2. A piston 33 is fixedly connected to the outer wall of one end of the push rod 32, and the push rod 32 is slidably connected to the inner wall of the sleeve 31. The free-stop support rod assembly 3 also includes a sealing ring 34 and a vent hole 35. The sealing ring 34 is installed on the outer wall of the piston 33, and the sealing ring 34 and the sleeve 31 are interference-fitted.

[0027] Sleeve 31 is hinged to the top of the inner wall of cabinet 1, and its interior is a hollow cylindrical cavity. One end of push rod 32 is hinged to the outer wall of cabinet door 2, and the other end is fixedly connected to piston 33. The diameter of push rod 32 is slightly smaller than the inner diameter of sleeve 31 to ensure smooth sliding. A sealing ring 34 is installed on the outer edge of piston 33. The sealing ring 34 is made of rubber and has an interference fit with the inner wall of sleeve 31 to form an airtight space. Vent hole 35 is opened on the outer wall of piston 33 to balance the pressure difference between the inside and outside of piston 33 during movement and to prevent push rod 32 from jamming due to negative pressure. When cabinet door 2 is opened and closed, push rod 32 drives piston 33 to slide inside sleeve 31. The friction between sealing ring 34 and sleeve 31 and the change in air pressure create damping, allowing cabinet door 2 to be suspended at any angle.

[0028] In this embodiment, the sliding fit between the push rod 32 and the inner wall of the sleeve 31, and the air pressure adjustment effect of the piston 33, allow the cabinet door 2 to be suspended at any angle, reducing the difficulty of operation.

[0029] In embodiment two, a first buffer pad 4 is adhered to the bottom of one outer wall of the cabinet 1, and a second buffer pad 5 is adhered to the bottom of one outer wall of the cabinet door 2. The first buffer pad 4 is located on one side of the second buffer pad 5. The first buffer pad 4 is located between two magnetic positioning balls 7, and the second buffer pad 5 is located between two magnetic positioning sleeves 6.

[0030] The magnetic positioning sleeve 6 is a ring-shaped magnet, embedded in the bottom of one side of the cabinet 1; the magnetic positioning ball 7 is a spherical magnet, fixed to the bottom of one side of the cabinet door 2. When closed, the magnetic positioning ball 7 is attracted to the inner wall of the magnetic positioning sleeve 6, achieving precise alignment and reducing shaking.

[0031] In this embodiment, the first buffer pad 4 and the second buffer pad 5 are respectively disposed in the contact area of ​​the cabinet 1 and the cabinet door 2. When closed, the elastic material absorbs the impact force, eliminates the metallic collision sound, and improves the user's comfort.

[0032] The bottom of one outer wall of the cabinet 1 is fixedly connected with symmetrically distributed magnetic positioning sleeves 6, and the bottom of one outer wall of the cabinet door 2 is fixedly connected with symmetrically distributed magnetic positioning balls 7, which are tightly attached to the inner wall of the magnetic positioning sleeves 6.

[0033] Sealing strips 8 are adhered to the outer walls on both sides and the bottom of the cabinet door 2, and the sealing strips 8 are attached to the connection between the cabinet 1 and the cabinet door 2. A handle 9 is welded to the outer wall on the other side of the cabinet door 2. An observation window 10 is adhered to the inner wall of the cabinet door 2.

[0034] The sealing strip 8 is bonded to three sides of the cabinet door 2, and when closed, it fits tightly against the edge of the cabinet 1, forming a dust barrier. The observation window 10 is an acrylic transparent panel, bonded to the inner wall of the cabinet door 2, and the edges of the observation window 10 are covered with rubber frames to prevent collision with the cabinet body.

[0035] Working principle:

[0036] Opening phase: The user pulls the cabinet door 2 outward through the handle 9, and the hinge causes the cabinet door 2 to rotate around the axis. At this time, the push rod 32 pushes the piston 33 to slide backward inside the sleeve 31, and the sealing ring 34 generates frictional damping with the inner wall of the sleeve 31. At the same time, the vent 35 releases the internal air pressure, allowing the cabinet door 2 to stay at any angle.

[0037] Hovering phase: When the cabinet door 2 is opened to the target angle, the combined action of the air pressure balance and friction between the piston 33 and the sleeve 31 counteracts the weight of the cabinet door 2, achieving stable hovering.

[0038] Closing Phase: The user gently pushes the cabinet door 2, and the magnetic attraction between the magnetic positioning ball 7 and the magnetic positioning sleeve 6 guides the cabinet door 2 to close precisely. At this time, the first buffer pad 4 and the second buffer pad 5 make contact first, absorbing the impact force through elastic deformation. Throughout the process, the buffer structure eliminates the sound of metal collisions, achieving silent closing.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
