Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to an adjustable hinge. Background Technology

[0002] Hinges, also known as hinges, are a common hardware accessory used to connect two solid objects, allowing them to rotate relative to each other around a pivot point. Traditional door hinges are folding hinges, with a main hinge and a secondary hinge hinged together. The main hinge is fixed to the door frame, while the secondary hinge is fixed to the door panel, thus achieving a rotating connection between the door panel and the door frame. However, traditional folding hinges only have a simple hinge function and cannot adjust the relative position of the main and secondary hinges to adjust the relative position of the door panel and the door frame. In addition, traditional folding hinges do not provide a buffer when opening and closing the door. When closing the door, if there is a large external force, the door panel and the door frame will collide violently, producing a loud noise. Moreover, the violent collision can easily cause excessive interaction force between the door panel and the door frame, which can damage the door panel or the door frame, affecting the service life of the door panel and the door frame, and also posing certain safety hazards. Utility Model Content

Detailed Implementation

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, 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 of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figure 1-5As shown, a preferred embodiment of this utility model of an adjustable hinge includes a fixed base 1, a mounting base 2, a connecting block 3, a hydraulic buffer shaft 4, and a hinge plate. The mounting base 2 is vertically adjustable and mounted on the fixed base 1. The connecting block 3 is horizontally adjustable and mounted on the mounting base 2, with one side of the connecting block 3 extending out of the mounting base 2. It should be noted that the hydraulic buffer shaft 4 is a relatively mature existing technology, such as the hydraulic shaft in a hydraulic hinge. The hydraulic buffer shaft 4 mainly includes a bushing 41, a shaft 42, and a shaft core mechanism. The shaft 42 is inserted into the bushing 41 and is connected to the bushing 41. The rotating mechanism is located inside the shaft 42. When the shaft 42 rotates relative to the bushing 41, the shaft mechanism can control the relative rotation speed of the bushing 41 and the shaft 42, thereby playing a buffering role. The bushing 41 is fixedly connected to the side of the connecting block 3 that extends out of the mounting base 2. The shaft 42 is fixedly connected to the hinge piece. In this embodiment, the upper and lower parts of the shaft 42 extend out of the bushing 41 and are fixedly provided with connecting sleeves 43. The connecting sleeves 43 are fixedly connected to the hinge piece for easy connection. An anti-wear ring 44 is provided between the connecting sleeve 43 and the bushing 41 to prevent wear.

[0023] The working principle of this embodiment is as follows: In use, the fixing seat 1 is installed and fixed on the door frame, and the hinge is fixed on the door panel. During installation, a mounting groove is usually opened on the door frame, and both the fixing seat 1 and the mounting seat 2 are embedded in the mounting groove. The fixing seat 1 is fixed in the mounting groove by bolts. When the position of the mounting seat 2 is adjusted up and down (relative to the fixing seat 1), the mounting seat 2 will move up and down together with the connecting block 3, the hydraulic buffer shaft 4, the hinge, and the door panel. When the position of the connecting block 3 is adjusted forward and backward (relative to the mounting seat 2), the connecting block 3 will move forward and backward together with the hydraulic buffer shaft 4, the hinge, and the door panel to achieve the position adjustment of the door panel. When the door is opened and closed, the door panel drives the hinge. Since the hinge is fixedly connected to the shaft 42, and the bushing 41 is fixedly connected to the connecting block 3, the shaft 42 rotates relative to the bushing 41. The hydraulic buffer shaft 4 will then play a buffering role, achieving the effect of hydraulic buffering door opening and closing.

[0024] For example, the fixing base 1 includes a fixing block 11, and the mounting base 2 is adjustable up and down on the rear side of the fixing block 11. The fixing block 11 is provided with a vertically arranged adjustment slot 111. The adjustment slot 111 is provided with a fixing bolt 12 connected to the mounting base 2. The fixing bolt 12 passes through the adjustment slot 111 and is connected to the mounting base 2. After the fixing bolt 12 is loosened (the fixing bolt 12 does not need to be completely separated from the mounting base 2), the position of the mounting base 2 can be adjusted up and down. After the adjustment is completed, the fixing bolt 12 is tightened again to achieve fixation.

[0025] For example, the upper front side and lower front side of the mounting base 2 are respectively provided with guide slopes 21. The guide slopes 21 gradually slope towards the front or rear from top to bottom, and the two guide slopes 21 have opposite inclination directions. The upper front side and lower front side of the mounting base 2 are respectively provided with fixing blocks 11. The fixing blocks 11 are threadedly connected with a first adjusting stud 13. The first adjusting stud 13 is arranged longitudinally (i.e., in the front-to-back direction). The first adjusting stud 13 passes through the fixing base 1 and its rear end abuts against the guide slope 21. Figure 2 As shown, in this embodiment, the guide slope 21 located on the upper part of the mounting base 2 gradually slopes forward from top to bottom, while the guide slope 21 located on the lower part of the mounting base 2 gradually slopes backward from top to bottom. When the first adjusting stud 13 on the fixing block 11 located on the upper front side of the mounting base 2 is tightened, since the fixing base 1 is fixed, the first adjusting stud 13 gradually moves backward. Under the action of the first adjusting stud 13 and the guide slope 21, the mounting base 2 will be driven to move downward gradually. Similarly, when the first adjusting stud 13 on the fixing block 11 located on the lower front side of the mounting base 2 is tightened, the mounting base 2 will be driven to move upward gradually, which facilitates the vertical adjustment of the mounting base 2.

[0026] For example, the front side of the mounting base 2 is provided with a vertically arranged positioning groove 14, and the guide slope 21 is located in the positioning groove 14, which is compactly connected. The rear side of the fixed base 1 is provided with a positioning block 22 that slides with the positioning groove 14, which can ensure that the mounting base 2 moves vertically (up and down) when the first adjusting stud 13 is tightened.

[0027] For example, the rear end of the first adjusting stud 13 is tapered from front to back to prevent jamming and ensure normal adjustment.

[0028] For example, the connecting block 3 is threadedly connected to a second adjusting stud 31. The second adjusting stud 31 is arranged longitudinally and is inserted into the mounting base 2 through the connecting block 3. The second adjusting stud 31 is rotatably connected to the mounting base 2. To prevent the second adjusting stud 31 from displacing during rotation, in this embodiment, the second adjusting stud 31 is provided with a first limiting block for limiting the movement of the second adjusting stud 31 towards the mounting base 2 and a second limiting block for limiting the movement of the second adjusting stud 31 away from the mounting base 2. When the second adjusting stud 31 is rotated, since the second adjusting stud 31 is rotatably connected to the mounting base 2 and the second adjusting stud 31 is threadedly connected to the connecting block 3, the connecting block 3 will move relative to the second adjusting stud 31, thereby realizing the adjustment of the connecting block 3 to the front or back.

[0029] For example, the connecting block 3 is connected with a locking bolt 32. The locking bolt 32 passes through the connecting block 3 and is threadedly connected to the mounting base 2. When the locking bolt 32 is in a tightened state, the connecting block 3 is in a fixed state and the front and rear positions of the connecting block 3 cannot be adjusted by the second adjusting stud 31, thus preventing the connecting block 3 from becoming loose.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
