Description

Technical Field

[0001] This utility model belongs to the field of hinge technology, and specifically relates to a surface-mounted hinge for doors and windows. Background Technology

[0002] Hinges are one of the most common hardware accessories in door and window fittings; they are generally used for hinged connections between frames and sashes.

[0003] Currently, hinges in most structures have adjustment functions, namely, adjustment in the X-axis direction (i.e., the width direction of the sash) and the Y-axis direction (i.e., the height direction of the sash). The X-axis direction mainly adjusts the fit between the locking point and the locking seat, while the Y-axis direction mainly adjusts the fit between the frame and the sash in the height direction, so as to facilitate installation adjustment.

[0004] In current structures, the upper hinge is typically adjusted in the Y-axis direction by adjusting the lower hinge. The upper hinge in the X-axis direction is usually adjusted by its own adjustment component. In existing upper hinge structures, the passive sliding in the Y-axis direction and the adjustment component in the X-axis direction are usually integrated together. This makes the entire adjustment component structure relatively complex, inconvenient to manufacture, and even more inconvenient to assemble. Utility Model Content

[0005] This invention provides a surface-mounted hinge that can solve the problems pointed out in the background art.

[0006] A surface-mounted hinge includes a hinge base, a bushing, a hinge plate connected to the bushing, upper fixing plates respectively disposed on both sides of the hinge plate, and an upper support. The bushing is rotatably connected to the hinge base via a hinge shaft. The bushing is adjusted along the hinge shaft in the Y-axis direction to ultimately achieve overall adjustment of the hinge plate, upper fixing plate, and upper support in the Y-axis direction.

[0007] Preferably, both the upper fixing plate and the upper support are "L" shaped parts. The upper end of the hinge plate is connected to the upper support by a supporting rivet, the hinge plate is connected to the upper fixing plate by a connecting rivet, and the upper fixing plate and the upper support are connected by a positioning rivet.

[0008] Preferably, the connecting rivet is an eccentric adjusting rivet, which adjusts the relative position of the upper fixed plate and the upper support in the Z-axis. A guide post and a guide hole are provided between the upper fixed plate and the upper support for adjustment and guidance.

[0009] Preferably, an X-axis adjustment assembly is provided between the upper fixed plate and the upper support, and the relative position of the upper fixed plate and the upper support in the X-axis direction is adjusted by the X-axis adjustment assembly.

[0010] Preferably, the X-axis adjustment assembly includes a screw bracket and an adjusting screw. The upper connecting end of the screw bracket is fixedly connected to the upper support. The screw bracket is provided with a threaded hole that mates with the adjusting screw. The upper fixed plate is provided with a sliding elongated hole that mates with the screw bracket at a corresponding position. The adjusting screw is located in the sliding elongated hole, and its threaded end passes through the threaded hole and rests on the corresponding inner wall of the sliding elongated hole.

[0011] Preferably, the hinge base is a "U"-shaped base, and the hinge shaft is a shoulder screw.

[0012] Beneficial effects: This utility model provides an exposed hinge that has separate and independent designs for the X-axis, Y-axis and Z-axis directions, allowing for independent adjustment without mutual interference. Compared with the original adjustment components, it simplifies the structure, facilitates manufacturing and assembly, and has better structural versatility. Attached Figure Description

[0018] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0019] Example 1: As Figure 1-3As shown in the figure, an exposed hinge provided by this utility model embodiment includes a hinge base 1, a bushing 2, a hinge plate 3 connected to the bushing 2, an upper fixing plate 4 and an upper support 5 respectively disposed on both sides of the hinge plate 3. The hinge base 1 is used to fix it to the frame, and the upper support 5 is used to fix it to the sash. The hinge base 1 is a "U" shaped base. The hinge shaft 6 is a shoulder screw, specifically a hexagonal head shoulder screw. The bushing 2 can be connected to the hinge plate 3 by rivets. The bushing 2 is rotatably connected to the hinge base 1 through the hinge shaft 6. The bushing 2 is adjusted along the hinge shaft 6 in the Y-axis direction (i.e., the height direction) to ultimately achieve the overall adjustment of the hinge plate 3, the upper fixing plate 4 and the upper support 5 in the Y-axis direction. When the hinge is adjusted in the Y-axis direction, the bushing 2 will make corresponding follow-up movements and adjustments along the hinge shaft 6 in the Y-axis direction under the drive of the sash.

[0020] Specifically, the upper end of the hinge plate 3 is connected to the upper support 5 by a supporting rivet 7, the hinge plate 3 is connected to the upper fixing plate 4 by a connecting rivet 8, and the upper fixing plate 4 and the upper support 5 are connected by a positioning rivet 9.

[0021] In some embodiments, the connecting rivet 8 is an eccentric adjustment rivet, which adjusts the relative position of the upper fixed plate 4 and the upper support 5 in the Z-axis (thickness direction of the fan). A guide post 10 and a guide hole 11 are provided between the upper fixed plate 4 and the upper support 5 for adjustment and guidance. Through this adjustment, the tightness of the sealing strip between the frame and the fan can be adjusted.

[0022] In some embodiments, an X-axis adjustment assembly is provided between the upper fixed plate 4 and the upper support 5, and the relative position of the upper fixed plate 4 and the upper support 5 in the X-axis direction (i.e., the width direction) is adjusted by the X-axis adjustment assembly.

[0023] Specifically, the X-axis adjustment assembly includes a screw bracket 12 and an adjusting screw 13. The upper connecting end of the screw bracket 12 is fixedly connected to the upper support 5. The screw bracket 12 is provided with a threaded hole 121 that mates with the adjusting screw 13. The upper fixed plate 4 is provided with a sliding elongated hole 14 that mates with the screw bracket 12 at a corresponding position. The adjusting screw 13 is located in the sliding elongated hole 14, and its threaded end passes through the threaded hole 121 and rests on the corresponding inner wall of the sliding elongated hole 14. The adjusting screw 13 can be an internal hexagon screw. By reciprocating the rotation of the adjusting screw 13, the relative adjustment of the X-axis between the upper fixed plate 4 and the upper support 5 can be driven.

[0024] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
