Description

Technical Field

[0001] This utility model relates to the field of hidden door installation technology, and more specifically to a hidden door anti-detachment structure and a hidden door. Background Technology

[0002] Hidden doors, also known as ghost doors or concealed doors, refer to doors with hidden or trackless designs, allowing them to blend seamlessly with their surroundings when closed. This greatly enhances the overall integrity and aesthetics of the space, making them widely used in environments with high requirements for spatial harmony, such as walk-in closets, studies, and bathrooms. The operation of hidden doors relies on specific connection and support structures. Currently, the most common method is to use L-shaped fasteners to open and close the door. The mounting part of the L-shaped fastener is fixed to the wall, serving as a stable support point. The connecting part of the L-shaped fastener has a guide component to guide the door, facilitating smooth sliding and enabling smooth opening and closing.

[0003] However, existing concealed doors typically abandon the side-mounted screw fixing method, leaving the door to rely solely on a single point connection between the L-shaped fastener and the wall for load-bearing. As the concealed door is used over time, frequent opening and closing, coupled with various external forces such as the door's weight and the inertia generated during opening and closing, causes the door to gradually shift closer to or further away from the wall. This leads to a gradual loosening of the connection between the door and the L-shaped fastener, potentially causing the door to detach and seriously threatening the safety of the concealed door.

[0034] Example 1

[0035] See Figure 1-10 As shown, this embodiment discloses a hidden door anti-detachment structure, applied to a door body 8 with a guide groove 81. The hidden door anti-detachment structure of this embodiment includes a fixing member 1, which has a mutually perpendicular mounting part 11 and a connecting part 12, with the connecting part 12 being horizontally arranged; it also includes a moving member 2, a guide component 3, and a fastener 4; the moving member 2 is slidably connected to the connecting part 12, and the moving member 2 can move closer to or further away from the mounting part 11 to a target position; the guide component 3 is connected to the moving member 2; the end of the guide component 3 away from the moving member 2 is used to insert into the guide groove 81, so that the door body 8 slides on the target trajectory; the fastener 4 is used to fix the moving member 2, which has moved to the target position, to the connecting part 12.

[0036] In practice, first connect the guide component 3 to the movable component 2, then connect the movable component 2 to the connecting part 12 using fasteners 4, and finally fix the mounting part 11 to the wall 9, thus completing the installation of the hidden door anti-detachment structure. When installing the door body 8, align the guide groove 81 with the guide component 3 so that the guide component 3 is inserted into the guide groove 81, thus completing the initial installation of the door body 8; drive the fasteners 4 away from the movable component 2, causing the movable component 2 to loosen from the fixing part 1. Based on the actual weight of the door body 8 and the specific usage environment, determine the distance between the door body 8 and the wall 9 and adjust the position of the door body 8. The movement of the door body 8 drives the guide component 3 to move, and the guide component 3 drives the movable component 2 to slide, causing the movable component 2 to reach the target position. Drive the fasteners 4 to fix the movable component 2 to the connecting part 12, thus completing the complete installation of the door body 8. If the door 8 shakes during use, the fastener 4 is driven to gradually move away from the moving part 2, causing the moving part 2 to loosen from the fixing part 1. Then the position of the door 8 is adjusted. The movement of the door 8 drives the guide component 3 to move, and the guide component 3 drives the moving part 2 to slide, so that the moving part 2 reaches the target position. The fastener 4 is then driven to fix the moving part 2 to the connecting part 12, thus completing the adjustment of the tightness of the door 8.

[0037] The concealed door anti-detachment structure of this embodiment, by setting a movable part 2 that slides on the fixed part 1, allows the movable part 2 to adjust the distance between the movable part 2 and the mounting part 11 according to the optimal distance between the door body 8 and the wall 9, thereby adjusting the tightness between the door body 8 and the wall 9. Combined with the setting of the fastener 4, it ensures the stability of the connection of the door body 8, improves the stability and safety of the concealed door in long-term use, and effectively reduces the risk of the concealed door falling off.

[0038] Specifically, the connecting part 12 is provided with an adjustment groove 121, which is perpendicular to the mounting part 11. The moving part 2 is provided with a movable part 5, which is movably connected to the adjustment groove 121. When the position of the door 8 needs to be adjusted, the door 8 moves, driving the guide assembly 3 to move. The guide assembly 3 is connected to the moving part 2, which in turn drives the moving part 2 to move. The moving part 2 is connected to the movable part 5, which in turn drives the movable part 5 to move within the adjustment groove 121 in a direction closer to or further away from the mounting part 11. The adjustment groove 121 provides precise guidance for the movement of the movable part 5, ensuring that the moving part 2 can drive the movable part 5 to move in the specified direction, thereby achieving precise adjustment of the distance between the door 8 and the wall 9. In addition, the adjustment groove 121 provides a limiting function for the movement of the movable part 5, so that the movable part 5 can only move within the adjustment groove 121, preventing the movable part 5 from detaching from the adjustment groove 121 during movement, which would cause the moving part 2 to detach from the fixing part 1, thus enhancing the reliability of the structure and further improving the stability and safety of the hidden door in long-term use.

[0039] Specifically, the adjusting groove 121 is provided with a first tooth 1211 perpendicular to the groove wall of the mounting part 11, and the movable part 5 is provided with a second tooth 51 corresponding to the first tooth 1211. The first tooth 1211 and the second tooth 51 mesh with each other. The setting of the first tooth 1211 and the second tooth 51 makes the moving part 5 step precisely, ensuring the adjustment accuracy of the door body 8; and the meshing first tooth 1211 and the second tooth 51 also play a role in positioning and locking during the movement of the movable part 5. When the movable part 2 reaches the target position, the meshing of the first tooth 1211 and the second tooth 51 can prevent the movable part 5 from accidentally sliding due to external force or vibration of the door body 8, making the position of the door body 8 more stable, further ensuring the reliability of the connection of the door body 8, and reducing the risk of the hidden door falling off.

[0040] Preferably, there are two adjusting grooves 121 and two movable parts 5. The two adjusting grooves 121 are symmetrically arranged on the connecting part 12, and the two movable parts 5 are respectively movably connected to the two adjusting grooves 121. The symmetrical arrangement of the two adjusting grooves 121 and the two movable parts 5 makes the force on the moving part 2 more even during the movement, ensuring the smooth movement of the moving part 2, better adapting to the adjustment needs of the door body 8, avoiding the tilting or shaking of the door body 8 due to uneven force, and greatly improving the stability of the adjustment of the door body 8.

[0041] Preferably, the number of guide components 3 is the same as the number of movable parts 5, and the guide components 3 are symmetrically distributed on the movable part 2. The two symmetrically arranged guide components 3 can make the force on the movable part 2 more even during movement, further improving the smoothness of movement of the movable part 2, making the overall structure more stable, and effectively extending the service life of the hidden door anti-detachment structure.

[0042] Specifically, the guide assembly 3 includes a connecting shaft 31 and a guide wheel 32. The connecting shaft 31 is vertically arranged and connected to the moving member 2, and the guide wheel 32 is horizontally arranged and rotatably connected to the connecting shaft 31. More specifically, the guide assembly 3 is located on the side of the moving member 2 away from the connecting part 12; the connecting shaft 31 and the guide wheel 32 pass through the guide groove 81, and the guide wheel 32 is in frictional engagement with the groove wall of the guide groove 81. When the door 8 moves, the guide groove 81 and the guide wheel 32 interact, and the guide wheel 32 rolls in the guide groove 81. The arrangement of the guide wheel 32 reduces the friction when the door 8 moves, making the opening and closing action of the door 8 smoother. When the distance between the door 8 and the wall 9 is adjusted, the groove wall of the guide groove 81 pushes the guide wheel 32 from a direction perpendicular to the wall 9, causing the guide wheel 32 to push the connecting shaft 31. The connecting shaft 31 drives the moving member 2 to move, so that the moving member 2 reaches the target position.

[0043] Specifically, the movable component 5 has a through hole 52, and the moving component 2 has a through hole 21 corresponding to the through hole 52. The connecting shaft 31 passes through and is fixedly connected to the through hole 21 and the through hole 52. The connecting shaft 31 is directly connected to the movable component 5, which shortens the force transmission path. When the distance between the door 8 and the wall 9 needs to be adjusted, the guide wheel 32 is pushed by the door 8, and the pushing force can be efficiently transmitted to the movable component 5 through the connecting shaft 31, causing the movable component 5 to move within the adjustment groove 121. This effectively avoids the force transmission lag or energy loss caused by indirect connection, enhances the response speed of the moving component 2, and helps to reduce the magnitude of external force. The user only needs to push the door 8 lightly to move the moving component 2, which improves the ease of operation and user experience of the hidden door anti-slip structure.

[0044] Specifically, the fastener 4 has a threaded portion 41 and a stop portion 42; the width of the stop portion 42 is greater than the diameter of the threaded portion 41. The threaded portion 41 is threaded onto the movable member 2, and the stop portion 42 abuts against the connecting portion 12. The threaded portion 41 is threaded onto the movable member 2, which can firmly fix the movable member 2 onto the connecting portion 12 by rotating the fastener 4; the width of the stop portion 42 is greater than the diameter of the threaded portion 41, so that the fastener 4 is always located on the side of the connecting portion 12 away from the movable member 2, and the other end is connected to the movable member 2, preventing the movable member 2 from detaching from the fixing member 1 and ensuring the stability of the connection between the movable member 2 and the connecting portion 12. When the threaded portion 41 is screwed into the movable member 2 until the stop portion 42 abuts against the connecting portion 12, the movable member 2 is locked, and at this time the movable member 2 cannot move further. When the position of the door 8 needs to be adjusted, rotate the fastener 4 to loosen the screw connection 41, and the moving part 2 can slide on the connecting part 12. After the adjustment is completed, tighten the fastener 4 again until the stop part 42 abuts against the connecting part 12, thus locking the position of the moving part 2 and ensuring the stability of the relative position between the moving part 2 and the connecting part 12. This, in turn, ensures the stability of the relative position between the door 8 and the wall 9, preventing the door 8 from falling off due to shaking or displacement, and greatly improving the safety of the hidden door.

[0045] Preferably, there are two fasteners 4, which are symmetrically arranged on the connecting part 12. The two fasteners 4 symmetrically arranged on the connecting part 12 can apply a balanced fixing force to the moving part 2, making the moving part 2 more securely fixed on the connecting part 12, effectively preventing the moving part 2 from shifting due to unilateral force, and further improving the stability of the door body 8 after installation and adjustment.

[0046] In this embodiment, the fastener 4 is a screw. More specifically, the stop portion 42 is a screw nut structure, and the threaded portion 41 is a screw thread shank structure. Screws are common and widely used standard parts with low cost, which helps to reduce the production and maintenance costs of the hidden door anti-detachment structure. Screws are easy to install and remove. They can be easily screwed into the moving part 2 with the help of a screwdriver or rotating tool to achieve a tight connection between the moving part 2 and the connecting part 12. When it is necessary to adjust the position of the door body 8 or to maintain the hidden door anti-detachment structure, the screws can also be easily unscrewed. The operation is simple and quick, greatly improving the overall installation and maintenance efficiency. It is understood that in other embodiments, rivets or self-tapping screws can be used instead of screws as needed.

[0047] Specifically, the fastener 4 and the guide component 3 are coaxially arranged; or, the fastener 4 and the guide component 3 are spaced apart along the width direction of the connecting portion 12. It can be understood that the width direction of the connecting portion 12 is parallel to the movement trajectory of the door body 8 and perpendicular to the extension direction of the adjustment groove 121. When the fastener 4 and the guide component 3 are coaxially arranged, when adjusting the position of the door body 8 or when the door body 8 is subjected to external force, the force can be transmitted more directly to the fastener 4 and the fixing component 1 through the guide component 3. The coincidence of the lines of action of the force reduces the offset and loss during the force transmission process, making the entire hidden door anti-detachment structure more stable under force, better able to withstand the weight and external force of the door body 8, and helping to enhance the stability of the door body 8 connection. The spaced-apart fastener 4 and guide component 3 make the fastener 4 and guide component 3 easier to operate during installation, avoiding spatial interference between the two, reducing the installation difficulty of the fastener 4 and guide component 3, and thus improving the installation efficiency of the hidden door anti-detachment structure and the adjustment efficiency of the door body position.

[0048] Specifically, the movable part 2 is also provided with an actuating element 6 for cooperating with the buffer 82 provided on the door body 8; the actuating element 6 is screwed to the movable part 2 via a fitting 7. More specifically, the actuating element 6 is located on the side of the movable part 2 away from the connecting part 12; the actuating element 6 is provided with a third screw hole 61, and the movable part 2 is provided with a fourth screw hole 23, and the fitting 7 is screwed into the third screw hole 61 and the fourth screw hole 23. The fitting 7 is used to fix the actuating element 6 to the movable part 2. The actuating element 6 is used to cooperate with the buffer 82 on the door body 8. When the door body 8 is opened or closed, the door body 8 moves until the buffer 82 contacts the actuating element 6, causing the actuating element 6 to trigger the buffer 82. The buffer 82 provides a buffering effect for the door body 8, reducing the moving speed of the door body 8 or hindering its movement, preventing the door body 8 from pinching hands, and improving the safety and user experience of the hidden door.

[0049] Example 2

[0050] See Figure 1-7As shown, this embodiment discloses a hidden door anti-detachment structure, based on the hidden door anti-detachment structure of Embodiment 1. Specifically, in this embodiment, the fastener 4 and the guide component 3 are spaced apart along the width direction of the connecting portion 12. More specifically, the connecting portion 12 is provided with a connecting groove 122, and the moving part 2 is provided with a first screw hole 22; the connecting groove 122 and the mounting part 11 are arranged perpendicularly to each other, and the groove width of the connecting groove 122 is smaller than the width of the stop part 42; the stop part 42 abuts against the side of the connecting portion 12 away from the moving part 2, and the screw part 41 passes through the connecting groove 122 and is screwed into the first screw hole 22.

[0051] The concealed door anti-detachment structure of this embodiment, by opening a connecting groove 122 in the connecting part 12 and providing a first screw hole 22 on the moving part 2, allows the fastener 4 to pass through the connecting groove 122 and the first screw hole 22 sequentially from top to bottom. Through the screw connection of the screw part 41 and the first screw hole 22, the fastener 4 and the moving part 2 are securely connected. By abutting the connecting part 12 from the side away from the moving part 2, the fastener 4 is supported on the connecting part 12, which greatly increases the friction between the stop part 42 and the connecting part 12, and achieves a stable connection between the fastener 4 and the connecting part 12. This, in turn, achieves a fixed connection between the moving part 2 and the fixed part 1, providing a solid guarantee for the long-term stable operation of the concealed door and significantly improving the stability and safety of the concealed door in long-term use. In addition, by using the groove width of the connecting groove 122 to limit the movement distance of the moving part 2, the controllability of the adjustment range of the moving part 2 is ensured, thereby improving the reliability of the concealed door anti-detachment structure.

[0052] Example 3

[0053] See Figure 1-4 and Figure 8-10 As shown, this embodiment discloses a hidden door anti-detachment structure, based on the hidden door anti-detachment structure of Embodiment 1. Specifically, in this embodiment, the fastener 4 and the guide component 3 are coaxially arranged. More specifically, the connecting shaft 31 is provided with a second screw hole 311, and the screwed part 41 passes through the adjusting groove 121 and is screwed into the second screw hole 311; the width of the stop part 42 is greater than the groove width of the adjusting groove 121, and the stop part 42 abuts against the side of the connecting part 12 away from the moving part 2.

[0054] In this embodiment, the hidden door anti-detachment structure, by providing a second screw hole 311 on the connecting shaft 31, allows the screwed portion 41 of the fastener 4 to be directly screwed onto the connecting shaft 31. The connecting shaft 31 is connected to the movable part 5, and the movable part 5 is connected to the moving part 2, thereby achieving a tight connection between the fastener 4 and the moving part 2. At the same time, the width of the stop portion 42 is greater than the width of the adjusting groove 121, and the stop portion 42 abuts against the connecting portion 12 from the side away from the moving part 2, increasing the friction between the stop portion 42 and the connecting portion 12, ensuring a stable connection between the fastener 4 and the connecting portion 12, and thus achieving a stable connection between the moving part 2, the guide component 3, and the fixing component 1, providing a solid guarantee for the long-term stable operation of the hidden door, and significantly improving the stability and safety of the hidden door in long-term use. The second screw hole 311 on the connecting shaft 31 avoids processing the connecting portion 12 and the moving part 2, ensuring the structural strength of the moving part 2 and the fixing component 1, further ensuring the stability of the overall structure, and thus extending the service life of the hidden door anti-detachment structure.

[0055] Example 4

[0056] See Figure 1-10 As shown, this embodiment discloses a hidden door, including: a door body 8, and a hidden door anti-detachment structure of embodiment two or three; the door body 8 is slidably connected to the hidden door anti-detachment structure. Specifically, the door body 8 is provided with a guide groove 81, and a connecting shaft 31 and a guide wheel 32 pass through the guide groove 81, with the guide wheel 32 in frictional engagement with the groove wall of the guide groove 81.

[0057] In this embodiment, the hidden door integrates an anti-detachment structure, allowing the door body 8 to move along the extension direction of the connecting part 12 under the guidance of the guide wheel 32, ensuring smooth opening and closing of the hidden door. The sliding engagement between the moving part 2 and the fixing part 1 allows the moving part 2 to adjust the position of the door body 8 according to the distance between the door body 8 and the wall 9, improving the flexibility and convenience of adjusting the tightness of the door body 8. The mutual engagement of the first meshing and the second meshing teeth 51, along with the use of the fastener 4, enhances the connection stability between the door body 8 and the fixing part 1, preventing the door body 8 from shaking during use, effectively reducing the risk of the door body 8 falling off the anti-detachment structure, and improving the safety and reliability of the hidden door.

[0058] The hidden door in this embodiment also includes a buffer 82, which is disposed on the door body 8. The actuating member 6 is used to cooperate with the buffer 82 on the door body 8. When the door body 8 is opened or closed, the door body 8 moves until the buffer 82 contacts the actuating member 6, causing the actuating member 6 to trigger the buffer 82. The buffer 82 provides a buffering effect for the door body 8, which reduces the moving speed of the door body 8 or obstructs its movement, preventing the door body 8 from pinching hands, and improving the safety and user experience of the hidden door.

[0059] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments.
