Description

Technical Field

[0001] This utility model relates to the field of door and window hinge technology, specifically to an invisible top and bottom hinge for a casement door. Background Technology

[0002] The concealed top and bottom hinge is a hinge structure that achieves a frameless and minimalist appearance through a hidden design. Its top and bottom hinges support and secure the door leaf by bearing weight from the top and bottom.

[0003] When installing top and bottom hinges, the door frame hinges are usually installed on the door frame, and the door leaf hinges are installed on the door leaf. Then, the pivot on the door leaf hinge is matched with the bushing on the door frame hinge to achieve a rotating connection between the door leaf and the door frame.

[0004] The accuracy of the installation position of door leaf hinges and door frame hinges on their respective door leaves or frames determines the user experience. When the installed door leaf hinges or door frame hinges deviate vertically from their preset positions, it can easily create a movable gap in the door leaf, making the fit between the door leaf and the door frame unstable. To eliminate this instability, the position of the door leaf hinges or door frame hinges usually needs to be adjusted. However, repeatedly tightening the screws on the door leaf hinges or door frame hinges that need adjustment can easily reduce the firmness of the fit between the screws and the corresponding door leaf hinges or door frame hinges. At the same time, using this method to improve the stability of the fit between the door leaf and the door frame increases the workload of the installer and is not conducive to eliminating the instability of the fit between the door leaf and the door frame in a short period of time, thus making it difficult to improve the installer's work efficiency.

[0005] Therefore, improving the efficiency of installers in eliminating the defects of unstable fit between the door leaf and the door frame during the installation of top and bottom hinges is a technical problem that urgently needs to be solved. Utility Model Content

[0006] The purpose of this utility model is to address the problem that current top and bottom hinges make it difficult for installers to quickly eliminate the instability between the door leaf and the door frame during installation. This invention provides an invisible top and bottom hinge for swing doors to improve the efficiency of installers in eliminating the instability between the door leaf and the door frame.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A concealed top and bottom hinge for a swing door includes a door leaf hinge and a door frame hinge. The door leaf hinge includes a door leaf fixing plate and a pivot. The door leaf fixing plate is used to fix the door leaf, and the pivot is movably engaged with the door leaf fixing plate, allowing the pivot to move relative to the door leaf fixing plate along its own length. An adjusting ring is rotatably connected to the door leaf fixing plate, and the adjusting ring is threadedly connected to the pivot. By rotating the adjusting ring, the pivot can move along its own length. The door frame hinge includes a bushing, and the pivot is used to extend into the bushing and abut against the end of the bushing.

[0009] As the preferred technical solution of this application, the door leaf fixing plate is provided with a locking block, the rotating shaft is provided with a locking groove, the length direction of the locking groove is in the same direction as the length direction of the rotating shaft, and the locking block is locked in the locking groove.

[0010] As the preferred technical solution of this application, the outer ring of the adjustment ring is hexagonal.

[0011] As the preferred technical solution of this application, the rotating shaft includes a rotating shaft part and a rotating shaft part, the rotating shaft part is sleeved outside the rotating shaft part, the rotating shaft part is threadedly engaged with the adjusting ring, and a spring is connected between the rotating shaft part and the rotating shaft part. The spring is elastic, and the length direction of the spring is in the same direction as the length direction of the rotating shaft. The spring is used to provide elastic force so that the rotating shaft part extends to the rotating shaft part when it is not subjected to external force.

[0012] One part of the rotating shaft is used to extend into the bushing, and the other part of the rotating shaft is used to abut against the end of the bushing.

[0013] As the preferred technical solution of this application, the end of the rotating shaft facing the bushing has a hemispherical structure.

[0014] As the preferred technical solution of this application, when the bushing and the rotating shaft are engaged, the side wall of a portion of the rotating shaft is in contact with the inner wall of the bushing, and the portion of the rotating shaft applies pressure to the inner wall of the bushing.

[0015] As a preferred technical solution of this application, the door frame hinge further includes a first fixing piece and a base. The first fixing piece is used to fix it to the door frame. The base is provided with a first mating groove. The first mating groove is used for the first fixing piece to pass through. The fixing piece can move along the length direction of the first mating groove to change the distance between the base and the door frame.

[0016] The base is also provided with several threaded holes, which are used to engage with the knob so that the knob abuts against the first fixing piece, thereby fixing the first fixing piece relative to the base.

[0017] As a preferred technical solution of this application, the door frame hinge further includes a second fixing piece, which is used to be placed inside the door frame. The first fixing piece and the second fixing piece are connected by screws, and the first fixing piece and the second fixing piece cooperate to clamp the door frame.

[0018] As the preferred technical solution of this application, the door frame hinge further includes a door frame stabilizing pad, which is used to be locked inside the door frame, and the second fixing piece is locked on the door frame stabilizing pad.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. In the solution of this application, by rotating the adjusting ring relative to the door leaf fixing piece, the rotating shaft moves along its own length direction, thereby adjusting the relative position between the rotating shaft and the door leaf fixing piece, and thus adjusting the relative position between the door leaf and the rotating shaft. After installing the door frame hinge on the door frame and the door leaf hinge on the door leaf, and then engaging the door leaf hinge with the door frame hinge, if there is a movable gap in the vertical direction of the door leaf, the adjusting ring can be rotated to adjust the distance between the part of the rotating shaft that abuts against the end of the bushing and the door leaf, thereby eliminating the movable gap in the vertical direction of the door leaf. During this process, There is no need to adjust the position of the door leaf hinges or door frame hinges, thus avoiding the need to adjust the screws on the corresponding door leaf hinges or door frame hinges. By adjusting the adjusting ring, the installer can quickly eliminate the defect of unstable fit between the door leaf and the door frame, thereby improving the installer's work efficiency. Furthermore, during the installation of the door leaf onto the door frame, the pivot can be moved closer to the door leaf hinge first, thereby reducing the length of the pivot extending from the door leaf fixing plate. This provides more space for the pivot to extend into the bushing during the fit between the door leaf hinge and the door frame hinge, further improving the convenience of the fit between the pivot and the bushing.

[0021] 2. Furthermore, when the adjusting ring is rotated to adjust the position of the rotating shaft relative to the door leaf fixing plate, the rotating shaft extends from the side of the door leaf fixing plate facing the door leaf. A mating hole is provided on the area of ​​the door leaf corresponding to the rotating shaft. The mating hole is used to accommodate the rotating shaft, which further facilitates the mating between the door leaf hinge and the door leaf. At the same time, since the mating hole can be pre-drilled on the door leaf, the door leaf fixing plate can be pre-maturing with the door leaf through the rotating shaft and the mating hole during the installation of the door leaf. This makes it easier to position the door leaf fixing plate relative to the door leaf and improves the accuracy of the installation of the door leaf fixing plate on the door leaf.

[0022] 3. Furthermore, the outer ring of the adjusting ring is set to be hexagonal so that the adjusting ring can be fitted with an external hex wrench, specifically a flat hex wrench. By locking the hex wrench onto the adjusting ring, the hex wrench drives the adjusting ring to rotate, thereby facilitating the adjustment of the position of the rotating shaft relative to the door leaf fixing plate.

[0023] 4. Furthermore, by setting a first rotating shaft and a second rotating shaft, and connecting the first rotating shaft and the second rotating shaft with a spring, during the process of the rotating shaft and the bushing engaging, the first rotating shaft extends into the bushing, the second rotating shaft abuts against the end of the bushing, and the spring is compressed. In this way, when the door leaf hinge engages with the door frame hinge, the stability of the first rotating shaft extending into the bushing is improved, and the risk of the first rotating shaft coming out of the bushing is reduced.

These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Example 1: This example provides a concealed top and bottom hinge for a swing door. See [link / reference]. Figures 1-3 As shown, the hinge includes a door leaf hinge 1 and a door frame hinge 2. The door leaf hinge 1 includes a door leaf fixing piece 3 and a rotating shaft 4. The door leaf fixing piece 3 is used to fix the door leaf. The rotating shaft 4 is movably engaged with the door leaf fixing piece 3, so that the rotating shaft 4 can move relative to the door leaf fixing piece 3 along its own length direction. An adjusting ring 5 is rotatably connected to the door leaf fixing piece 3. The adjusting ring 5 is threadedly connected to the rotating shaft 4. By rotating the adjusting ring 5, the rotating shaft 4 can move along its own length direction. The door frame hinge 2 includes a bushing 6. The rotating shaft 4 is used to extend into the bushing 6 and abut against the end of the bushing 6.

[0034] In this application, by rotating the adjusting ring 5 relative to the door leaf fixing piece 3, the rotating shaft 4 moves along its own length direction, thereby adjusting the relative position between the rotating shaft 4 and the door leaf fixing piece 3, and thus adjusting the relative position between the door leaf and the rotating shaft 4. After installing the door frame hinge 2 on the door frame and the door leaf hinge 1 on the door leaf, and then engaging the door leaf hinge 1 with the door frame hinge 2, if there is a movable gap in the vertical direction of the door leaf, the adjusting ring 5 can be rotated to adjust the distance between the part of the rotating shaft 4 that abuts against the end of the bushing 6 and the door leaf, thereby eliminating the movable gap in the vertical direction of the door leaf. During this process, it is not necessary to... The position of the door hinge 1 or the door frame hinge 2 is adjusted to avoid adjusting the screws on the corresponding door hinge 1 or door frame hinge 2. By adjusting the adjusting ring 5, the installer can quickly eliminate the defect of unstable fit between the door and the door frame, thereby improving the installer's work efficiency. In addition, during the installation of the door on the door frame, the pivot 4 can be moved closer to the door hinge 1 to reduce the length of the pivot 4 extending from the door fixing piece 3. This provides more space for the pivot 4 to extend into the bushing 6 during the fit between the door hinge 1 and the door frame hinge 2, further improving the convenience of the fit between the pivot 4 and the bushing 6.

[0035] Furthermore, when the adjusting ring 5 is rotated to adjust the position of the rotating shaft 4 relative to the door leaf fixing piece 3, the rotating shaft 4 extends from the side of the door leaf fixing piece 3 facing the door leaf. A mating hole is provided on the area of ​​the door leaf corresponding to the rotating shaft 4. The mating hole is used to accommodate the rotating shaft 4, which further facilitates the mating between the door leaf hinge 1 and the door leaf. At the same time, since the mating hole can be pre-drilled on the door leaf, the door leaf fixing piece 3 can be pre-maturing with the door leaf through the rotating shaft 4 and the mating hole during the installation of the door leaf fixing piece 3. This makes it easier to position the door leaf fixing piece 3 relative to the door leaf and improves the accuracy of the installation of the door leaf fixing piece 3 on the door leaf.

[0036] As a preferred embodiment, based on the above method, the door leaf fixing piece 3 is further provided with a locking block 7, and the rotating shaft 4 is provided with a locking groove 8. The length direction of the locking groove 8 is the same as the length direction of the rotating shaft 4, and the locking block 7 is locked in the locking groove 8.

[0037] Furthermore, by setting the slot 8 and the block 7, the block 7 is locked in the slot 8. When the adjusting ring 5 is rotated, the block 7 can move relative to the slot 8 along the length direction of the slot 8, and the rotating shaft 4 moves relative to the door hinge 1 along the length direction of the rotating shaft 4, thus improving the stability of the movement of the rotating shaft 4.

[0038] As a preferred embodiment, based on the above method, the outer ring of the adjusting ring 5 is further hexagonal.

[0039] Furthermore, the outer ring of the adjusting ring 5 is set to be hexagonal so that the adjusting ring 5 can be adapted to an external hex wrench, specifically a flat hex wrench. By locking the hex wrench onto the adjusting ring 5, the hex wrench drives the adjusting ring 5 to rotate, thereby facilitating the adjustment of the position of the rotating shaft 4 relative to the door leaf fixing piece 3.

[0040] In a preferred embodiment, based on the above method, the rotating shaft 4 further includes a rotating shaft part 9 and a rotating shaft part 10. The rotating shaft part 10 is sleeved outside the rotating shaft part 9. The rotating shaft part 9 is threadedly engaged with the adjusting ring 5. A spring 11 is also connected between the rotating shaft part 9 and the rotating shaft part 10. The spring 11 is elastic. The length direction of the spring 11 is in the same direction as the length direction of the rotating shaft 4. The spring 11 is used to provide elastic force so that the rotating shaft part 9 extends to the rotating shaft part 10 when it is not subjected to external force.

[0041] The first part of the rotating shaft 9 is used to extend into the bushing 6, and the second part of the rotating shaft 10 is used to abut against the end of the bushing 6.

[0042] Furthermore, by setting a first rotating shaft 9 and a second rotating shaft 10, and connecting the first rotating shaft 9 and the second rotating shaft 10 with a spring 11, during the process of the rotating shaft 4 engaging with the bushing 6, the first rotating shaft 9 extends into the bushing 6, the second rotating shaft 10 abuts against the end of the bushing 6, and the spring 11 is compressed. In this way, when the door hinge 1 engages with the door frame hinge 2, the stability of the first rotating shaft 9 extending into the bushing 6 can be improved, and the risk of the first rotating shaft 9 coming out of the bushing 6 can be reduced.

[0043] Example 2: Based on the technical solution of Example 1, further details are provided below. Figures 1-3 As shown, the end of the rotating shaft 9 facing the bushing 6 has a hemispherical structure.

[0044] Furthermore, the end of the rotating shaft 9 facing the bushing 6 is made into a hemispherical structure, which makes it easier for the rotating shaft 9 to extend into the bushing 6 and facilitates the fit between the rotating shaft 9 and the bushing 6.

[0045] As a preferred embodiment, based on the above method, when the bushing 6 and the rotating shaft 4 are engaged, the side wall of the rotating shaft part 9 is in contact with the inner wall of the bushing 6, and the rotating shaft part 9 applies pressure to the inner wall of the bushing 6.

[0046] Furthermore, when the bushing 6 and the rotating shaft 4 are engaged, the rotating shaft part 9 can apply pressure to the inner wall of the bushing 6, thereby further improving the stability of the engagement between the rotating shaft part 9 and the bushing 6.

[0047] In a preferred embodiment, based on the above method, the door frame hinge 2 further includes a first fixing piece 12 and a base 13. The first fixing piece 12 is used to fix to the door frame. The base 13 is provided with a first mating groove 14. The first mating groove 14 is used for the first fixing piece 12 to pass through. The fixing piece can move along the length direction of the first mating groove 14 to change the distance between the base 13 and the door frame.

[0048] The base 13 is also provided with a plurality of threaded holes, which are used to engage with the knob in a threaded manner so that the knob abuts against the first fixing piece 12, thereby fixing the first fixing piece 12 relative to the base 13.

[0049] Furthermore, by providing threaded holes on the base 13, the threaded holes engage with the knob, thereby causing the knob to abut against the first fixing piece 12 passing through the first mating groove 14, thus fixing the first fixing piece 12 relative to the base 13. This facilitates fixing the relative position between the base 13 and the door frame when adjusting the distance between them, and further improves the flexibility of adjusting the relative position of the door leaf and the door frame. At the same time, the top and side surfaces of the first mating groove 14 each correspond to at least two threaded holes, which further enhances the stability of fixing the first fixing piece 12.

[0050] In a preferred embodiment, based on the above method, the door frame hinge 2 further includes a second fixing piece 15, which is used to be placed inside the door frame. The first fixing piece 12 and the second fixing piece 15 are connected by screws, and the first fixing piece 12 and the second fixing piece 15 cooperate to clamp the door frame.

[0051] In a preferred embodiment, based on the above method, the door frame hinge 2 further includes a door frame stabilizing pad 16, which is used to be locked inside the door frame, and the second fixing piece 15 is locked on the door frame stabilizing pad 16.

[0052] Furthermore, by setting the second fixing piece 15 and the door frame stabilizing pad 16, the stability of the first fixing piece 12 relative to the door frame can be further improved when the first fixing piece 12 and the second fixing piece 15 cooperate, thereby improving the stability of the door frame and the door leaf.

[0053] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
