Description

Technical Field

[0001] This utility model relates to a protective mechanism, specifically a furniture cushioning and protective mechanism. Background Technology

[0002] In the daily use of furniture products, the frequent opening and closing of doors is an extremely common operation. However, this process is often accompanied by many problems, which adversely affect the user experience and the lifespan of the furniture.

[0003] Traditional furniture doors, lacking effective cushioning, often generate significant impact when opening or closing. When the door closes, this impact causes a violent collision between the door and the furniture frame, producing loud noise, disrupting the user's living environment, and causing wear and tear on both the door and the frame. Over time, the door edges may warp, the paint may peel, and the joints of the furniture frame may loosen, severely affecting the overall aesthetics and structural stability of the furniture.

[0004] Meanwhile, while existing cushioning devices can alleviate the impact of door opening and closing to some extent, most suffer from limited cushioning effectiveness and lack of adjustability. Different types of furniture doors, due to variations in material, size, and weight, require different levels of cushioning force. For example, heavier solid wood doors require greater cushioning force to ensure smooth opening and closing, while lighter plastic doors require less to maintain flexibility. However, existing cushioning devices cannot be flexibly adjusted according to the specific characteristics of the door, limiting their applicability and failing to meet diverse market demands.

[0031] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0032] Example 1, by Figure 1-4 This utility model provides a furniture cushioning and protection mechanism, comprising:

[0033] Buffer mechanism 1 is fixedly installed on the inner side wall of the furniture;

[0034] The adjustment mechanism 3 is connected to the buffer mechanism 1 via the connecting pipe 2 and is detachably connected to the inner wall of the furniture.

[0035] The buffer mechanism 1 includes:

[0036] The first cylinder 4 has a first piston chamber 5 and a moving chamber 7 that are coaxially connected inside it. The diameter of the moving chamber 7 is smaller than that of the first piston chamber 5.

[0037] The first piston 6 is slidably disposed within the first piston chamber 5;

[0038] The movable component includes a movable block 8 slidably embedded in the movable cavity 7 and a movable rod 9 fixedly connected thereto. The free end of the movable rod 9 is connected to the mounting plate 12 through a rotating connector. The mounting plate 12 is adapted to be fixed to the furniture door.

[0039] The adjustment mechanism 3 includes:

[0040] The second cylinder 13 is set vertically, and a second piston chamber 14 is provided inside it;

[0041] The second piston 15 is slidably disposed in the second piston chamber 14 and forms a hydraulic connection with the first piston chamber 5 through the connecting pipe 2;

[0042] The adjusting assembly includes a piston rod 16 fixed to the top of the second piston 15 and a counterweight plate 17 detachably disposed at the top of the piston rod 16.

[0043] Buffer mechanism 1: Fixedly installed on the inner wall of the furniture. It includes a first cylinder 4, inside which are a first piston chamber 5 and a moving chamber 7 coaxially connected, the diameter of the moving chamber 7 being smaller than that of the first piston chamber 5. A first piston 6 is slidably disposed within the first piston chamber 5. The moving assembly includes a moving block 8 slidably embedded in the moving chamber 7 and a moving rod 9 fixedly connected thereto. The free end of the moving rod 9 is connected to a mounting plate 12 via a rotating connector, and the mounting plate 12 is adapted to be fixed to the furniture door. The rotating connector includes an arc-shaped block 10 fixedly connected to the free end of the moving rod 9 and a concave block 11 fixedly disposed in the middle of the mounting plate 12. The arc-shaped block 10 is rotatably embedded in the arc-shaped groove of the concave block 11 via a rotating shaft. The inner wall of the moving chamber 7 is provided with a polytetrafluoroethylene wear-resistant layer, and the outer surface of the moving block 8 is provided with a ceramic coating that cooperates with the wear-resistant layer, which can effectively reduce friction during movement. The first piston 6 is provided with a double-lip seal ring around its periphery. The outer lip of the double-lip seal ring is interference-fitted with the inner wall of the piston cavity to ensure the sealing of the piston cavity.

[0044] Adjustment mechanism 3: Connected to buffer mechanism 1 via connecting pipe 2, and detachably connected to the inner wall of the furniture. Adjustment mechanism 3 includes a vertically arranged second cylinder 13, which has a second piston chamber 14 inside. The second piston 15 is slidably disposed in the second piston chamber 14 and hydraulically connected to the first piston chamber 5 via connecting pipe 2. The adjustment assembly includes a piston rod 16 fixed to the top of the second piston 15 and a counterweight plate 17 detachably disposed at the top of the piston rod 16. The top of the piston rod 16 has a threaded connection, and the bottom of the counterweight plate 17 has a matching threaded groove, facilitating the replacement of counterweight plates of different weights. Connecting pipe 2 is a bendable corrugated metal pipe, with both ends connected to the first cylinder 4 and the second cylinder 13 via quick connectors, forming a sealed connection for easy installation and disassembly. The periphery of the second piston 15 is also provided with a double-lip sealing ring to ensure the sealing of the second piston chamber 14.

[0045] The buffer mechanism 1 and the adjustment mechanism 3 can be encapsulated within the housing.

[0046] Working principle: When this invention is used, the mounting plate 12 installed on the door will first move when the furniture door is opened or closed. Since the moving rod 9 is connected to the mounting plate 12 through the rotating connector (the cooperation of the arc block 10 and the concave block 11), the movement of the mounting plate 12 will drive the moving rod 9 to move. The other end of the moving rod 9 is fixedly connected to the moving block 8, which is slidably embedded in the moving cavity 7. Therefore, the movement of the moving rod 9 drives the moving block 8 to slide in the moving cavity 7.

[0047] As the door rotates to its final position, the sliding of the moving block 8 further pushes the first piston 6 to move within the first piston chamber 5. Because the first piston chamber 5 and the second piston chamber 14 are hydraulically connected via the flexible metal bellows connecting pipe 2, the movement of the first piston 6 within the first piston chamber 5 changes the pressure distribution of the hydraulic oil within it. According to Pascal's law, the pressure is transmitted to the second piston chamber 14 through the hydraulic oil in the connecting pipe 2, thereby pushing the second piston 15 to move accordingly within the second piston chamber 14.

[0048] In this process, the adjusting mechanism 3 plays a crucial role in regulating the buffering effect. The piston rod 16 is fixedly attached to the top of the second piston 15, and a counterweight plate 17 is detachably mounted on the top of the piston rod 16. Different weights of the counterweight plate 17 apply different magnitudes of pressure to the piston rod 16, which is transmitted to the second piston 15 through the piston rod 16. When the second piston 15 is subjected to different magnitudes of pressure, the resistance it encounters as it moves within the second piston chamber 14 also varies. For example, increasing the weight of the counterweight plate 17 will cause the second piston 15 to be subjected to greater downward pressure. When the first piston 6 pushes the hydraulic oil to transmit pressure, it will be more difficult for the second piston 15 to move. The resistance of the hydraulic oil flowing in the connecting pipe 2 will increase, thereby enhancing the buffering effect of the buffer mechanism 1. The door will be subjected to a greater buffering force during opening and closing, and the moving speed will be slower. Conversely, reducing the weight of the counterweight plate 17 will reduce the pressure on the second piston 15, making it easier to move. The resistance of the hydraulic oil flow will decrease, the buffering effect of the buffer mechanism 1 will weaken, and the door will open and close relatively faster. The weight of the counterweight plate 17 will not be able to exert enough force on the moving rod 9 to open the door under normal conditions.

[0049] In addition, the inner wall of the moving cavity 7 in the buffer mechanism 1 is provided with a polytetrafluoroethylene wear-resistant layer, and the outer surface of the moving block 8 is provided with a matching ceramic coating. The two effectively reduce the friction force when the moving block 8 slides in the moving cavity 7, ensuring smooth operation of the moving component and making the buffering process more stable. At the same time, the double-lip sealing rings around the first piston 6 and the second piston 15 have their outer lips pressed against the inner wall of the piston cavity, ensuring good sealing of the first piston cavity 5 and the second piston cavity 14, maintaining the stability of the pressure transmission of the hydraulic system, and ensuring that the entire buffer protection mechanism can operate stably and efficiently, providing reliable buffer protection for the furniture door.

[0050] Beneficial effects: It can effectively buffer the opening and closing of furniture doors, reduce collision and wear between the door and the furniture body, and extend the service life of the furniture.

[0051] The adjustment mechanism allows for the adjustment of the cushioning effect by replacing the counterweight plates of different weights, making it adaptable to furniture doors of different weights and different users' needs for cushioning effect, thus possessing strong flexibility and practicality.

[0052] The inner wall of the moving cavity in the buffer mechanism is provided with a polytetrafluoroethylene wear-resistant layer, and the outer surface of the moving block is provided with a matching ceramic coating. This effectively reduces the friction when the moving block slides in the moving cavity, ensuring smooth operation of the moving component and making the buffering process more stable.

[0053] The double-lip seals around the first and second pistons have their outer lips pressed against the inner wall of the piston chamber, ensuring good sealing of the first and second piston chambers, maintaining the stability of the hydraulic system pressure transmission, and ensuring that the entire buffer protection mechanism can operate stably and efficiently, providing reliable buffer protection for the furniture door.

[0054] The buffer and adjustment mechanisms can be encapsulated within the housing to protect the internal structure.

[0055] The connecting pipe is a flexible corrugated metal pipe, with quick connectors at both ends forming a sealed connection with the first and second cylinders, facilitating installation and disassembly.

[0056] The rotating connector (the combination of the arc-shaped block and the concave block) allows the connection between the moving rod and the mounting plate to rotate, adapting to the opening and closing movements of the door.

[0057] The piston rod has a threaded connection at the top and a matching threaded groove at the bottom of the counterweight plate, making it easy to replace counterweight plates of different weights.

[0058] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
