Description

Technical Field

[0001] The utility model relates to a connecting piece for installing doors and windows, in particular to a hinge capable of fine adjustment. Background Art

[0002] In the prior art, doors are generally connected to door frames by hinges, and in the actual installation process, installation dislocation and deviation are prone to occur. Once installation dislocation and deviation occur, it is necessary to ask professionals to dismantle the door and reinstall it, which is time-consuming, labor-intensive and costly. In addition, as time goes by, when the door is affected by gravity, it will fall slightly, and the traditional hinge does not have an adjustment function, so it can only be reinstalled, which is very troublesome to operate. Moreover, for wooden doors, the screws used during installation cause irreversible damage to the wooden doors, so when it is necessary to adjust the position of the door, this is a more difficult problem. At the same time, when adjusting the position of the door, the corresponding screws need to be loosened, which will make the hinge and the door movable, especially for heavier doors. It will cause a certain shear force on the screws themselves, reducing the service life of the screws, and at the same time increasing the difficulty of turning the screws, and even causing the screws to completely loosen, causing the door to fall, which is dangerous.

The first connecting portion 6 is installed in the lower cavity 13, and the first sliding portion 7 is installed in the upper cavity 14. The width of the lower cavity 13 is greater than the width of the upper cavity 14 (the width direction is the horizontal direction) and greater than the width of the first connecting portion 6. The width of the upper cavity 14 is the same as that of the first sliding portion 7, and the depth of the upper cavity 14 is greater than the depth of the first sliding portion 7 (the depth direction is the vertical direction). When the third adjusting screw 22 is loosened, the first connecting portion 6 and the first sliding portion 7 are relatively fixed. The third adjusting screw 22 can move in the vertical waist-shaped hole 20, that is, the second mounting seat 5 moves relative to the first sliding portion 7 in the vertical direction, so as to realize the adjustment in the vertical direction. When the second adjusting screw 17 is loosened, the first sliding portion 7 and the second mounting seat 5 are relatively fixed. The second adjusting screw 17 can move in the horizontal waist-shaped hole 15, that is, the second mounting seat 5 and the first sliding portion 7 move relative to the first connecting portion 6 in the horizontal direction, so as to realize the adjustment in the horizontal direction.

[0030] The upper cavity 14 penetrates through the second mounting seat 5 to increase the adjustment distance of the first sliding portion 7.

[0031] A stepped portion 23 is provided on the first sliding portion 7. The horizontal waist-shaped hole 15 is provided on the stepped portion 23. A notch 24 is provided on the upper cavity 14 corresponding to the stepped portion 23. The stepped portion 23 is fitted into the notch 24.
