[0023] Please see Figures 1 to 9 This application provides a pre-positioned hidden three-dimensional hinge, including a first hinge assembly, a second hinge assembly, and a rotating silent sleeve 3.

[0024] The first hinge assembly includes a fixed base 11, a first adjusting base 12, a first adjusting screw 13, and an adjusting wheel 14. The fixed base 11 has a first fixing hole 111. During installation, the screw passes through the first fixing hole 111 to fix the fixed base 11 to the door frame. The first adjusting base 12 slides on the fixed base 11 along the Y-axis. The fixed base 11 has a sliding groove 112, which is set along the Y-axis. A slider 121 is integrally formed on the first adjusting base 12. The slider 121 slides in the sliding groove 112, thereby realizing that the first adjusting base 12 slides on the fixed base 11 along the Y-axis.

[0025] The first adjusting seat 12 has a first adjusting groove 122 arranged along the Y-axis and a second adjusting groove 123 arranged along the L-axis. One end of the first adjusting screw 13 passes through the first adjusting groove 122 and is screwed into the fixed seat 11. The first adjusting screw 13 is a countersunk hexagonal screw, which is used to fix the fixed seat 11 and the first adjusting seat 12 together.

[0026] The adjusting wheel 14 includes a rotating wheel 141, an adjusting column 142, and a rotating shaft 143. The adjusting column 142 is vertically fixed on one side of the rotating wheel 141, and its central axis does not coincide with the central axis of the rotating wheel 141, meaning the adjusting column 142 is at an off-center position on the rotating wheel 141. The end face of the adjusting column 142 has a cross-shaped adjusting groove or an internal hexagonal groove, allowing it to be turned using a screwdriver or similar tool. The rotating shaft 143 is vertically fixed on the side of the rotating wheel 141 away from the adjusting column 142, and its central axis coincides with the central axis of the rotating wheel 141. 143 is pivotally connected to the fixed seat 11, and the rotating wheel 141 is also pivotally connected to the fixed seat 11. The adjusting column 142 extends into the second adjusting groove 123. Loosen the first adjusting screw 13, rotate the adjusting column 142, and drive the adjusting wheel 14 to rotate. Since the center of the adjusting wheel 14 is pivotally connected to the fixed seat 11, when the position of the adjusting column 142 in the second adjusting groove 123 changes, it correspondingly pushes the first adjusting seat 12 to move along the Y-axis, thereby adjusting the position between the first adjusting seat 12 and the fixed seat 11, and thus realizing the position adjustment between the door and the fixed seat 11 on the Y-axis.

[0027] The second hinge assembly includes a fixing block 21, a second adjusting screw 22, and a second adjusting seat 23. The second adjusting seat 23 has a third adjusting groove 231 and a rotating groove 232. The fixing block 21 is slidably disposed in the third adjusting groove 231 along the X-axis. Specifically, the third adjusting groove 231 has a first step 2311, the middle of the fixing block 21 has a second step 211, the second step 211 is engaged with the first step 2311, and the fixing block 21 has a second fixing hole 212. After the fixing block 21 is fastened in the third adjusting groove 231, people use screws to pass through the second fixing hole 212 to fix the fixing block 21 on the door, thereby realizing the adjustment of the door leaf.

[0028] One end of the second adjusting screw 22 is fixedly provided with an adjusting cap 221, which is located in the rotating groove 232. The end of the second adjusting screw 22 away from the adjusting cap 221 is screwed into the fixing block 21. The fixing block 21 is fixedly installed on the door, and the second adjusting seat 23 is stuck between the door and the fixing block 21. When the second adjusting screw 22 is rotated by turning the adjusting cap 221, a relative displacement is generated between the adjusting cap 221 and the fixing block 21. Since the adjusting cap 221 is located in the rotating groove 232, it does not generate displacement with the second adjusting seat 23, thereby driving the second adjusting seat 23 to generate relative displacement with the fixing block 21, thereby realizing the position adjustment between the two, and thus realizing the position adjustment between the door and the door frame.

[0029] The fixing block 21 has anti-slip texture 213 on one end face that passes through the third adjusting groove 231, i.e. Figure 8As shown, the lower end of the fixing block 21 is provided with anti-slip texture 213. The design of anti-slip texture 213 makes it more difficult for the fixing block 21 to slide after it is fixed on the door. The fixing block 21 has a herringbone groove 214 to reduce the weight of the fixing block 21 and save materials. The second adjusting seat 23 has an adjusting tooth 234. The function of the adjusting tooth 234 is that when the adjusting cap 221 on the second adjusting screw 22 is rotated to adjust the distance of the second adjusting seat 23, the adjusting tooth 234 can be slightly embedded in the door body, thereby increasing the movement distance of the second adjusting seat 23. On the other hand, after the adjusting tooth 234 is embedded in the door body, the connection between the second hinge assembly and the door is further made more stable.

[0030] A linkage shaft 15 is fixed on the first adjusting seat 12, and the second adjusting seat 23 is pivotally connected to the linkage shaft 15. The specific structure is as follows: an extension is integrally formed on the first adjusting seat 12, the extension is perpendicular to the first adjusting seat 12, the linkage shaft 15 is vertically fixed on the extension, and a rotating hole 233 is opened on the second adjusting seat 23. A rotating silent sleeve 3 is fitted on the linkage shaft 15 and inserted into the rotating hole 233. The rotating silent sleeve 3 is made of nylon material. After the second adjusting seat 23 is fitted on the linkage shaft 15 by the rotating silent sleeve 3, noise caused by metal-to-metal friction can be avoided during operation. With the addition of the rotating silent sleeve 3, the noise during rotation can be minimized.

[0031] Specifically, the first adjusting seat has a limiting hole 16 at one end with a linkage shaft, and the projection of the limiting hole 16 is arc-shaped. The second adjusting seat also has a positioning protrusion 239, which is accommodated within the limiting hole 16 and can move along the limiting hole 16. When the positioning protrusion 239 moves from one end of the limiting hole 16 to the other end, the second adjusting seat rotates 90° relative to the first adjusting seat. By moving the positioning protrusion 239 within the limiting hole 16, the relative rotation range of the first and second adjusting seats can be limited, thereby pre-positioning the door's rotation angle and preventing damage caused by excessive opening and closing of the door. In other embodiments, when the positioning protrusion 239 moves from one end of the limiting hole 16 to the other end, the second adjusting seat can also rotate at other angles relative to the first adjusting seat.

[0032] Working principle: During installation, screws are passed through the first fixing hole 111 to fix the fixing seat 11 to the door frame; screws are passed through the second fixing hole 212 to fix the fixing block 21 to the door; the second adjusting seat 23 is fitted onto the linkage shaft 15 by rotating the silent sleeve 3, so that the door can rotate around the linkage shaft 15; when adjustment is needed, the first adjusting screw 13 is loosened, and the adjusting column 142 is rotated, which drives the adjusting wheel 14 to rotate. Since the center of the adjusting wheel 14 is pivotally connected to the fixing seat 11, when the position of the adjusting column 142 in the second adjusting groove 123 changes, the first adjusting seat 12 is pushed accordingly along the Y-axis. The door moves along the axial direction, thereby adjusting the position between the first adjusting seat 12 and the fixed seat 11, thus achieving position adjustment between the door and the fixed seat 11 on the Y-axis. On the other hand, the second adjusting seat 23 is locked between the door and the fixed block 21. When the adjusting cap 221 is turned, the second adjusting screw 22 rotates, and a relative displacement occurs between the adjusting cap 221 and the fixed block 21. Since the adjusting cap 221 is located in the rotating groove 232 and does not move with the second adjusting seat 23, the relative displacement between the second adjusting seat 23 and the fixed block 21 is generated, thereby achieving position adjustment between the two, and thus achieving position adjustment between the door and the door frame.

[0033] It should be noted that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., are used only for the convenience of describing this application 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 application. The directional terms "inner" and "outer" refer to the inside or outside relative to the outline of the component itself. For example, if a device in the drawings is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0034] It should also be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this application refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application.
