Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, and in particular relates to a door hinge. Background Art

[0002] There are various hinge structures on the market. However, due to their structural reasons, existing hinges need to be installed at an eccentric position on the side of the door, or must be installed at a position close to a set distance on one side of the end face. Regardless of the size of the end face, a set distance must be reserved on one side of the end face so that the door can be opened normally. This results in the door having directionality when installing hinges. For example, if the hinge hole is opened in the wrong direction when opening a hole, the door will not be able to be opened. For example, Figure 1 and Figure 2 As shown, the active point of the two connecting plates of the hinge is mainly the middle position of the two connecting plates, which causes the hinge to rotate almost around the middle position, making the edge positions of the two connecting plates close to each other. When opening a hole, the hole needs to be opened at a position about 4mm away from the edge of the door end face. Therefore, when opening a hole on the door, there is a great limitation on the position from the hole to the edge. For door panels with different thicknesses, the opening position is mostly eccentric, so the opening has directionality, which is inconvenient, and because one side is too thin, the quality will also be affected. . Utility Model Content

[0003] The technical problem to be solved by the utility model is how to design the hinge so that the distance between the two connecting plates can be larger after the hinge is opened, so that the hole can be opened in the middle position when the hole is on one side of the door thickness, so as to facilitate the hole opening and avoid the wrong hole being opened.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A three-dimensional adjustable concealed hinge without left or right distinction comprises a first connecting plate and a second connecting plate, wherein the first connecting plate is fixedly or integrally provided with a connecting portion extending outward, and a first movable plate and a second movable plate are connected between the second connecting plate and the connecting portion, wherein one end of the first movable plate and the second movable plate are connected to different positions on the connecting portion through a pin shaft, and the second connecting plate is provided with a groove for the connecting portion, the first movable plate and the second movable plate to be embedded when rotating, and the other ends of the first movable plate and the second movable plate are respectively connected to different positions on the wall on one side of the groove through a pin shaft.

[0006] Preferably, the second connecting plate is fixedly connected with connecting pieces at both ends of the groove, and the first movable plate and the second movable plate are respectively connected between the two connecting pieces through pins.

[0007] Preferably, the connecting portion comprises a transverse straight section and an arc section, wherein the arc section is arranged away from the first connecting plate.

[0008] Preferably, both the first connecting plate and the second connecting plate are provided with decorative covers.

[0009] Preferably, an adjustment plate is provided on the second connecting plate, the adjustment plate is fixedly matched with the door, an adjustment slot is provided on the adjustment plate, and the second connecting plate and the adjustment plate are fixed by fasteners passing through the adjustment slot.

[0010] Preferably, an adjustment groove is provided on the first connecting plate, and the fastener fixes the first connecting plate to the door frame through the adjustment groove.

[0011] The beneficial effects of the utility model are as follows: the utility model provides an outwardly extending connecting portion on the first connecting plate connected to the door frame, and connects two movable plates on the connecting portion, and the two movable plates are then connected to the second connecting plate, so that the rotation point is located on the second connecting plate on the door, so that when the hinge rotates, the distance between the first connecting plate and the second connecting plate is larger, which can adapt to most doors of different thicknesses on the market, so that the hinge opening can be opened in the middle of the door thickness surface, so that the door panel is not distinguished between left and right, which is convenient for opening holes and avoids opening the wrong hole.

[0021] The utility model is further described below in conjunction with the embodiments.

[0022] like Figure 3-Figure 9The three-dimensional adjustable concealed hinge shown in FIG. 1 comprises a first connecting plate 1 and a second connecting plate 2, wherein the first connecting plate 1 is fixedly or integrally provided with a connecting portion 11 extending outward, wherein the first connecting plate 1 is fixedly connected to the door frame, and in order to be able to fine-tune the position of the first connecting plate 1 on the door frame, an adjustment slot 3 is provided on the first connecting plate 1 in this embodiment, and a fastener fixes the first connecting plate 1 to the door frame through the adjustment slot 3. For aesthetics, a decorative cover 6 is provided on the first connecting plate 1 and the second connecting plate 2 in this embodiment, and it is worth noting that a first movable plate 4 and a second movable plate 5 are connected between the second connecting plate 2 and the connecting portion 11 in this embodiment, wherein one end of the first movable plate 4 and the second movable plate 5 are connected to different positions on the connecting portion 11 through a pin shaft, and a groove 21 is provided on the second connecting plate 2 for the connecting portion 11, the first movable plate 4, and the second movable plate 5 to be embedded when rotating, and the other ends of the first movable plate 4 and the second movable plate 5 are respectively connected to different positions on the wall on one side of the groove 21 through a pin shaft. In this embodiment, the first connecting plate 1 has no complex structure and is only a plate. It does not need to be grooved on the door frame, which reduces the groove cutting process of the door frame and avoids the situation where the installation cannot be performed due to inaccurate groove position of the door frame. Compared with the existing similar hinges, the installation is more convenient and quick.

[0023] In order to facilitate the connection between the two movable plates and the second connecting plate 2, in this embodiment, the second connecting plate 2 is fixedly connected with connecting pieces 22 at both ends of the groove 21, and the first movable plate 4 and the second movable plate 5 are respectively connected between the two connecting pieces 22 through pins. During installation, the two connecting pieces 22 are first connected to the two movable plates, and then the two connecting pieces 22 are respectively fixed on the second connecting plate 2. A depth-adjustable control mechanism is set between the connecting piece 22 and the second connecting plate 2. This mechanism is a prior art and is not related to the technical problem to be solved by the present application, so it will not be elaborated here.

[0024] In order to allow the connection portion 11 to be accommodated in the groove 21 and to prevent the second connection plate 2 from being too large, the connection portion 11 in this embodiment is designed to include a horizontal straight section 111 and an arc section 112, wherein the arc section 112 is arranged away from the first connection plate 1. The design of the arc section 112 allows the arc section 112 to be easily accommodated in the groove 21 when the door is closed. Since the arc shape just matches the arc shape formed when the hinge rotates, the groove 21 can be made relatively small. If a straight section is used here, the size of the groove 21 will be larger, and the size of the entire second connection plate 2 will be larger, which will lead to an increase in cost.

[0025] In order to be able to fine-tune the position of the second connecting plate 2 on the door, the present embodiment provides an adjustment plate 23 on the second connecting plate 2, the adjustment plate 23 is fixedly matched with the door, an adjustment slot 3 is provided on the adjustment plate 23, the second connecting plate 2 and the adjustment plate 23 are fixed by fasteners passing through the adjustment slot 3, the adjustment slot 3 on the adjustment plate 23 and the adjustment slot 3 on the first connecting plate 1 are arranged perpendicularly to facilitate multi-directional adjustment of the entire hinge, and three-dimensional adjustment is achieved in conjunction with adjustment in the depth direction of the hinge, thereby achieving an ideal installation position.

[0026] The above shows and describes the basic principle, main features and advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, simple changes and substitutions by ordinary technicians in this field are within the protection scope of the utility model.
