Description

Technical Field

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

[0002] A hinge is a device that allows a door to open and close smoothly by rotating naturally. It is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can be made of movable components or foldable materials. Hinges are commonly used on doors, cabinets, boxes, and other similar items.

[0003] In modern life, people often prefer to replace simple parts themselves to reduce costs. However, when replacing hinges themselves, a lack of experience often leads to misalignment, which may require re-drilling holes and cause unsightly damage to the door, cabinet, or other mounting components. In severe cases, it can even damage the mounting components. To address the problem of installation failure due to misaligned holes, we propose an adjustable hinge to solve these issues. Summary of the Invention

[0037] Example 1

[0038] Please see Figure 1-4 This utility model discloses an adjustable hinge, including a first fixed structure 100, a second fixed structure 200, and an adjustment mechanism 300. The first fixed structure 100 includes a hinge assembly 110, and the second fixed structure 200 includes a fixedly connected limiting frame 1 and a mounting plate 2. The adjustment mechanism 300 is installed within the limiting frame 1, connecting the first fixed structure 100 and the second fixed structure 200. The adjustment mechanism 300 can adjust the distance between the first fixed structure 100 and the second fixed structure 200 in a straight line.

[0039] This device can adjust the distance between the first fixed structure 100 and the second fixed structure 200 in the straight line direction through the adjustment mechanism 300, thereby adjusting the opening and closing position so that the moving mechanism of the door, window and other doors can be closed smoothly with the fixed structure of the door frame, window frame and other doors.

[0040] The adjustment mechanism 300 of this device can use the length adjustment structure in the prior art. In this embodiment, the following adjustment mechanism 300 is specifically used.

[0041] The adjustment mechanism 300 includes a first limiting plate 7, a second limiting plate 8, an adjustment plate 11, a threaded rod 14, and an adjustment rod 15.

[0042] The first limiting plate 7 and the second limiting plate 8 are fixedly installed at both ends of the inner side of the limiting frame 1. The first limiting plate 7 has a sliding hole 10. The adjusting plate 11 is installed between the first limiting plate 7 and the second limiting plate 8 and can slide freely in the limiting frame 1. The adjusting plate 11 has a threaded hole 12. More specifically, the adjusting plate 11 slides within the range of the limiting frame 1 between the first limiting plate 7 and the second limiting plate 8.

[0043] One end of the adjusting rod 15 is connected to the first fixed structure 100, and the other end passes through the sliding hole 10 and is connected to the adjusting plate 11.

[0044] The threaded rod 14 includes a first end 141 and a second end 142. The first end 141 abuts against the first contact 71 of the first limiting plate 7, and the second end 142 passes through the second contact 72 of the second limiting plate 8. A rotary adjustment element 20 is provided on the second end 142. The thread of the threaded hole 12 matches the thread of the threaded rod 14. The threaded rod 14 can have different diameters between and outside the first and second limiting plates 7 and 8, thereby confining the threaded rod 14 between the first and second limiting plates 7 and 8. Lubricating oil can be applied to the first contact 71 and the second contact 72 to increase the smoothness of rotation. The rotary adjustment element 20 can be configured as a knob, a Phillips head screw, or a similar structure.

[0045] The working principle of this utility model is as follows:

[0046] In use, the second fixing structure 200 is first installed and fixed on the main frame of the door frame, window frame, etc., and then holes are drilled on the door or window sash. When the position is misaligned and needs to be adjusted, the threaded rod 14 can be rotated. Due to the threaded connection between the threaded hole 12 and the threaded rod 14, the adjusting plate 11 will move left and right inside the limiting frame 1. As the adjusting plate 11 moves, it can push the adjusting rod 15 to move inside the sliding hole 10, thereby adjusting the position of the first fixing structure 100, aligning the hole position of the first fixing structure 100 with the hole position on the door or window sash, and finally adjusting the opening and closing position of the door or window sash.

[0047] Furthermore, a stabilizing plate 9 is fixedly connected to the side of the first limiting plate 7 and the second limiting plate 8, and the bottom end of the stabilizing plate 9 is fixedly connected to the inner side wall of the limiting frame 1. The stabilizing plate 9 can enhance the fixing effect between the first limiting plate 7, the second limiting plate 8 and the limiting frame 1.

[0048] Furthermore, the inner sidewall of the limiting frame 1 has two guide grooves 17, and the adjusting plate 11 is provided with guide blocks 18 that match the guide grooves 17. The guide blocks 18 can slide within the guide grooves 17. More preferably, the guide blocks 18 can be engaged within the guide grooves 17, which makes the adjusting plate 11 move more smoothly within the guide grooves 17.

[0049] Furthermore, the hinge assembly includes an adjusting seat 5 and a mounting frame 6. The adjusting seat 5 is hinged to the mounting frame 6 via a rotating pin, and the mounting frame 6 has a connecting hole 19 inside. Multiple connecting holes 19 can be provided, and these holes 19 can be equidistantly arranged. A reinforcing block 16 is fixedly connected to the adjusting seat 5, and the adjusting seat 5 can be further connected to the adjusting mechanism 300 via the reinforcing block 16.

[0050] Furthermore, mounting holes 3 are provided on the upper surface of the mounting plate 2. When fixing the mounting plate 2 to the frame body, screws or nails can be used to pass through the mounting holes 3 to achieve fixation.

[0051] Furthermore, the upper surface of the mounting plate 2 is provided with a reinforcing wedge 4, which abuts against the limiting frame 1. The reinforcing wedge 4 is used to reinforce and fix the limiting frame 1.

[0052] Example 2

[0053] In this embodiment, unlike Embodiment 1, where the connecting holes 19 are equidistantly distributed when there are multiple holes, in this embodiment, the connecting holes 19 include a first hole position 191 and a second hole position group 192. The second hole position group 192 includes several sub-hole positions, and the spacing between the sub-hole positions of the second hole position group 192 is equal and less than the minimum spacing between the first hole position 191 and the second hole position group 192. In other words, when there are three or more hole positions, the first hole position 191 is the first hole position closer to the hinge structure, while the other relatively distant hole positions are configured as the second hole position group 192. The spacing between all hole positions in the second hole position group 192 is equal and set to L1. Among the several hole positions in the second hole position group 192, the distance between the hole position closest to the first hole position 191 and the first hole position 191 is set to L2, and L1 should be less than L2. The advantage of this is that the first hole 191 is relatively far away from the second hole group 192. When subjected to external force, L2 can generate a longer torque, thereby balancing a larger external force.

[0054] Example 3

[0055] In this embodiment, unlike in Embodiment 1, bearings 13 are installed on both the first contact 71 and the second contact 71. The threaded rod 14 is connected to the first limiting plate 7 at the first contact 71 via the bearing 13, and the threaded rod 14 is connected to the second limiting plate 8 at the second contact 72 via the bearing 13. The bearing 13 includes an inner ring and an outer ring. The inner ring is fixedly connected to the threaded rod 14, and the outer ring is connected to the first limiting plate 7 and the second limiting plate 8, so that the threaded rod 14 can rotate flexibly while being firmly fixed and not coming off.
