Detailed Implementation

[0018] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0019] This embodiment provides specific and implementable technical details for the above-mentioned inventive solution, in order to solve the problems of the exposed installation of traditional damping devices in the prior art, which affects aesthetics, occupies internal space, and is cumbersome to disassemble and assemble. Example

[0020] Please see Figures 1 to 7As shown, this utility model discloses a damping device for opening and closing furniture cabinet doors, including component A 1 and component B 2; component A 1 is a damping mating part, and component B 2 is a damping buffer part; in order to solve the problems of traditional damping devices being exposed and affecting the aesthetics of furniture and occupying space, as well as the problems of the cumbersome installation, disassembly and maintenance process of existing devices and the inability to achieve quick disassembly; therefore, component A 1 needs to be structurally optimized to meet the installation requirements.

[0021] Furthermore, component A 1 includes a base 11, a connector 12, and an elastic reset component. The base 11 has a concave cavity with an opening on one side. An elastic reset component is located at the opening inside the concave cavity. One end of the elastic reset component is connected to the bottom of the cavity, and the other end elastically acts on the lower side of the connector 12. The end of the connector 12 away from the elastic reset component is movably connected to the cavity. The end of the connector 12, which is the elastic reset component, has a protruding adapter seat 19. Component B is fitted and connected to the adapter seat 19.

[0022] The key to the above structural design lies in the fact that one end of the connector 12 is movably connected to the concave cavity, and the other end is connected to the elastic reset member. In this embodiment: Preferably, the elastic reset member includes a reset spring 14 and a positioning post 17. The positioning post 17 is disposed at the bottom of the cavity, and the reset spring 14 is sleeved on the positioning post 17. One end of the reset spring 14 is connected to the bottom of the cavity, and the other end elastically acts on the lower side of the connector 12. The connector 12 has a through hole 15 with a diameter larger than that of the positioning post 17 at the position corresponding to the positioning post 17. The upper end of the positioning post 17 passes through the connector 12 and is connected with a bolt. The connector 12 can move axially along the positioning post 17.

[0023] Preferably, in order to achieve the movable connection between the connector 12 and the cavity, the connector 12 is provided with the same elastic reset member below the end away from the elastic reset member. The elastic reset member includes a reset spring 14 and a positioning post 17. The positioning post 17 is located at the bottom of the cavity, and the positioning post 17 is covered with the reset spring 14. The positioning post 17 can play a fixed support role for the reset spring 14, which helps to stabilize the contraction performance of the reset spring 14. One end of the reset spring 14 is connected to the bottom of the cavity, and the other end elastically acts on the lower side of the connector 12.

[0024] Preferably, the connector 12 has a through hole 15 at the position corresponding to the positioning post 17. The diameter of the through hole 15 is larger than that of the positioning post 17. The upper end of the positioning post 17 passes through the connector and is connected to the bolt. The connector can move along the axial direction of the positioning post.

[0025] Preferably, the connector 12 is provided with an adapter 19 at one end pointing to the outside of the cavity. The adapter 19 extends from its connection end with the connector 12 in a direction away from the bottom of the cavity to form a protruding platform or column, thereby enhancing the strength of the load.

[0026] The adapter 19 has a connection slot 13, which is a square slot that fits into the rotating shaft 24 of component B.

[0027] Preferably, component B 2 is a damping buffer, consisting of a damping body 21 and a rotating shaft 24. The damping body 21 is a sealed shell encapsulating a damping medium (such as silicone oil) and a damping mechanism. The shell is typically made of metal or high-strength engineering plastic to ensure sealing and durability. The damping body contains a rotor mechanism driven by the rotating shaft. When the rotor rotates in the viscous medium, it generates a viscous force that hinders motion, i.e., a damping force. One end of the rotating shaft 24 extends from the center of the end cap of the damping body 21, and the rotating shaft 24 is connected to the rotor inside the damping body 21. Its rotation directly drives the rotor to move in the damping medium.

[0028] Preferably, the end of the rotating shaft 21 is machined into a square shaft head, which is fitted and connected to the square connecting slot 13 on the adapter 19 in component A 1.

[0029] Preferably, a positioning rib 22 is provided axially on the outer shell of the damping body 21 to cooperate with the guide groove 42 on the door panel 4 to prevent the B component 2 from rotating; an integrally formed mounting base 23 is provided on one side of the damping body 21, and one or more mounting holes are provided on the mounting base. In this embodiment, the mounting holes on the mounting base are countersunk holes or through holes, which are used to fix the B component to the mounting part 43 of the door panel 4 by screws.

[0030] Preferably, the base 11 is a one-piece metal stamping part, preferably made of aluminum alloy, serving as a support and mounting foundation. The base 11 has a concave cavity (i.e., an upward-opening cavity) with a depth of approximately 10-20mm. One end of the concave cavity is also open, providing space for the axial movement of the end of the adapter seat 19 in the connector 12.

[0031] Preferably, the positioning post 17 is cylindrical, with a height lower than the depth of the cavity, and a positioning hole 18 is provided at the upper end of the positioning post 17.

[0032] Preferably, the base 11 has a screw hole 110 at one end, and a mounting reinforcement seat 16 is also provided on one side of the concave cavity. The mounting reinforcement seat has a rib structure to increase the rigidity of the base and prevent deformation. The mounting reinforcement seat 16 is integrally formed with the base to enhance strength. The mounting reinforcement seat 16 has a locking hole 161 for fixing the base to the furniture cabinet 3 with screws.

[0033] Preferably, the connector 12 is a block-shaped component made of metal or high-strength engineering plastic. The upper part of the connector 12 has a through hole 15 that matches the outer diameter of the positioning post 17 (slightly larger than the diameter of the positioning post, allowing the connector to slide axially), with a tolerance controlled within 0.1-0.2 mm to ensure smooth sliding. The connector 12 is fitted onto the positioning post 17 through the through hole 15 and can slide smoothly along its axial direction.

[0034] Preferably, the upper end of the positioning post 17 is provided with a positioning hole 18, and the bolt passes through the through hole 15 of the connector 12 and connects with the positioning hole 18 of the positioning post 17, thereby restricting the connector 12 on the positioning post 17 to prevent it from falling off, but allowing the connector 12 to slide along the axial direction of the positioning post 17.

[0035] Preferably, the return spring 14 is a compression spring, which is sleeved on the outside of the positioning post 17. One end of the return spring 14 abuts against the bottom of the concave cavity, and the other end elastically acts on the inner side of the connector 12 (i.e., the lower surface of the connector). The wire diameter, number of coils, and free length of the spring are designed according to the damping requirements. When the connector 12 is compressed, the return spring 14 is compressed; when the pressure is released, the return spring 14 pushes the connector 12 to return to its original position.

[0036] Preferably, when the connector 12 is pressed with a finger, the return spring 14 contracts and moves away under the action of external force, and the connector 12 descends to the bottom until the upper surface of the adapter 19 is flush with the upper surface of the base 11. Preferably, when the adapter 19 is pressed with a finger, the other end of the connector 12 (i.e. the end that is movably connected to the concave cavity) is not under force and will not move downward. Under the action of external force, the return spring 14 contracts and moves to make room, and the end of the connector 12 pointing to the adapter 19 descends to the bottom until the upper surface of the adapter 19 is flush with the upper surface of the base 11.

[0037] Both pressing methods can make the upper surface of the adapter 19 flush with the upper surface of the base 11, making installation and disassembly convenient.

[0038] The specific implementation principle of the technical solution in this embodiment is as follows: Both component A1 and component B2 can be embedded into the pre-set mounting positions of the furniture cabinet body 3 and door panel 4. The pre-set mounting positions are grooves opened on the door panel or cabinet body, and their dimensions match the shape of component A1 and component B2.

[0039] During installation, the base 11 is securely fixed to the predetermined installation position of the furniture cabinet 3 using screws or bolts through its locking holes 161. A guide groove 42, corresponding to the positioning rib 22 of component B 2, is machined into the pre-set mounting groove 41 of the furniture cabinet door 4. During installation, the positioning rib 22 is aligned and slid into the guide groove 42, and then bolted to the mounting part 43 of the door panel 4 via the mounting base 23. This effectively prevents component B from rotating around its axis during operation, ensuring its fixed installation position. After installation, the outer surfaces of components A 1 and B 2 are flush with the furniture cabinet, preserving aesthetics and saving space.

[0040] Then, press down on the connector 12 or adapter 19 with your finger. Under the action of external force, the return spring 14 retracts and moves away, and the connector 12 or adapter 19 descends to the bottom until the upper surface of the adapter 19 is flush with the upper surface of the base 11. At this point, align the rotating shaft 24 on the cabinet door 4 with the connecting slot 13 of the connector 12, and then release your hand. Under the rebound action of the return spring 14, the connector 12 and the adapter 19 will reset, completing the engagement and connection between the rotating shaft 24 and the connecting slot 13.

[0041] The quick installation is now complete.

[0042] When it is necessary to disassemble door panel 4, simply use a tool to press down on connector 12 or adapter 19, and the rotating shaft 24 can be disengaged from the connecting slot 13. Then, hold door panel 4 and lift it upwards. The entire disassembly process is not only simple to operate, but also avoids damage to the furniture structure caused by repeated disassembly and assembly, achieving efficient and rapid maintenance of the furniture. Example

[0043] The difference between this embodiment and Embodiment 1 lies in the configuration of the elastic reset member, specifically: Preferably, the elastic reset component is a reset spring 14. One end of the reset spring 14 is connected to the bottom of the cavity, and the other end is connected to the lower side of the connector 12. The connector 12 does not need to have a hole at the position corresponding to the reset spring 14; it only needs to be fixedly connected to the reset spring 14. Example

[0044] The technical feature that differs from Embodiment 1 is the different way the connector 12 is connected to the concave cavity. Specifically: Preferably, a positioning post 17 is provided below the end of the connector 12 away from the elastic reset member. One end of the positioning post 17 is connected to the bottom of the cavity, and no reset spring is required outside the positioning post 17. In this case, the positioning post 17 serves to support and connect the connector 12.

[0045] Preferably, the connector 12 is also provided with a through hole at the position corresponding to the positioning post 17. The diameter of the through hole is smaller than the diameter of the positioning post 17, so that the positioning post 17 can support the end of the connector 12. Preferably, the upper end of the positioning post 17 is movably connected to the connector 12 by bolts, and the connector 12, the positioning post 17, and the bolts maintain a certain gap and can move relative to each other.

[0046] In this embodiment, when the adapter 19 is pressed with a finger, the return spring 14 contracts and moves away under the action of external force, and the adapter 19 descends to the bottom until the upper surface of the adapter 19 is flush with the upper surface of the base 11. Example

[0047] Please see Figure 8 The difference between this embodiment and Embodiment 1 lies in the different way the connector 12 is connected to the concave cavity. Specifically: Preferably, the end of the connector 12 away from the elastic reset member is provided with a connecting shaft 121, and the inner side of the concave cavity is provided with a shaft connecting sleeve 111. The shaft connecting sleeve is integrally formed with the base 11. The connector 12 is connected to the shaft connecting sleeve 111 through the connecting shaft 121, and the connector 12 can rotate around the connecting shaft.

[0048] In this embodiment, when the adapter 19 is pressed with a finger, the return spring 14 contracts and moves away under the action of external force, and the adapter 19 descends to the bottom until the upper surface of the adapter 19 is flush with the upper surface of the base 11.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
