Description

Technical Field

[0001] The utility model relates to a hinge, in particular to a novel adjustable hinge. Background Art

[0002] In the field of furniture manufacturing such as doors and windows, traditional hinges are widely used to connect door leaves and door frames to achieve the opening and closing function of the door leaves. Traditional hinges are mainly designed for the opening and closing function, and lack consideration for adjustability. During use, users are often unable to adjust the hinges according to actual needs, thereby failing to effectively solve the problem of incomplete closure or difficulty in closing due to the deviation between the door leaf and the door frame. In order to solve the problem of hinges without adjustment function, existing hinges will set long holes on the hinge pieces to meet the purpose of adjusting the installation position, but under heavy load conditions, the screws are easily displaced in the long hole position, causing the adjustment work to fail. The technical problem to be solved by the utility model is that the existing technical solution of adjusting the adjustable hinges by setting long holes on the hinge pieces is prone to screw displacement under heavy load conditions.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] According to the contents of the claims and the description, the specific implementation is as follows:

[0028] Implementation method:

[0029] The adjustable hinge of the utility model mainly comprises four main components: a door frame hinge (1), a door leaf hinge (2), an eccentric shaft (3) and a shaft sleeve (4).

[0030] 1. Door frame hinge (1): The door frame hinge (1) is provided with a door frame connecting plate (14) for connecting the door frame. The central axis of the lower shaft hole (11) of the door frame hinge (1) is eccentrically arranged with the central axis of the outer circle of the shaft of the door frame hinge (1). At the same time, the upper end of the lower shaft hole (11) is provided with a side locking groove (12) for engaging with the locking teeth (34) of the eccentric shaft. The lower end surface of the lower shaft hole (11) is semi-embedded with a lower cover (13) for protecting internal parts.

[0031] 2. Door hinge (2): The door hinge (2) is provided with a door connecting plate (23) for connecting the door leaves, and an upper cover (22) is semi-embedded on the upper end surface of the upper shaft hole (21) for protecting the internal parts.

[0032] 3. Eccentric shaft (3): The eccentric shaft (3) comprises an upper shaft (31), a connecting block (32), and a lower shaft (33). The connecting block (32) is provided with a marking notch (35) for adjusting the positioning. The upper shaft (31) and the lower shaft (33) are eccentrically arranged with respect to the central axis, and the upper end of the lower shaft (33) is provided with a locking tooth (34) for locking the door frame hinge (1).

[0033] 4. Shaft sleeve (4): The shaft sleeve (4) is embedded in the lower end of the upper shaft hole (21) of the door hinge (2) and is sleeved with the upper shaft (31).

[0034] With the above design, the user can use a hexagonal wrench to connect the hexagonal adjustment hole (36) on the end face of the lower shaft (33) to rotate and adjust the relative angle between the lower shaft (33) and the door frame hinge (1) to control the position between the upper shaft (31) and the door frame hinge (1) to adjust the position state between the door leaf hinge (2) and the door frame hinge (1), thereby achieving the adjustability of the door frame hinge and the door leaf hinge. The problem that the existing adjustable hinge is prone to screw displacement under heavy load conditions is solved.

[0035] Therefore, the technical solution of the utility model effectively solves the problem of difficult adjustment of existing hinges, improves the adjustability and stability of the hinges, and provides users with a more convenient usage experience.

[0036] The states of the door frame hinge (1) and the upper shaft (31) in different states are described as follows:

[0037] like Figure 3-5 As shown, the marking notch (35) is set at Figure 3 , Figure 4 In the position shown, the axis center of the upper shaft (31) is coaxially arranged with the axis center of the lower shaft hole (11), so the positions of the door frame hinge (1) and the door leaf hinge (2) are in the initial state.

[0038] like Figure 6-8 As shown, the marking notch (35) is set at Figure 6 , Figure 7 In the position shown, the axis center position of the upper shaft (31) is set in the X and -Y directions of the axis center of the lower shaft hole (11), and the cross-sectional view is shown in Figure 8. At this time, the door leaf hinge (2) is located in the X and -Y directions of the door frame hinge (1).

[0039] like Figure 9-11 As shown, the marking notch (35) is set at Fig. 9 , Fig.10 In the position shown, the axis center position of the upper shaft (31) is set in the X direction of the axis center of the lower shaft hole (11), and the cross-sectional view is shown in Figure 11. At this time, the door leaf hinge (2) is located in the X direction of the door frame hinge (1).

[0040] According to the needs of installation, the installer can adjust the relative position of the door leaf hinge (2) and the door frame hinge (1) by adjusting the angle of the lower shaft (33). After the adjustment is completed, because the part where the door frame hinge (1) is connected to the door frame is connected to the door frame through the round hole by screws, and the part where the door leaf hinge (2) is connected to the door leaf is connected to the door leaf through the round hole by screws, this connection method is more stable, and the problem of screw displacement under heavy load is reduced to a very low level.

[0041] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
