Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a novel hidden hinge. Background Art

[0002] The publication number is CN217176212U, and the subject name is: Chinese Utility Model Patent for a Concealed Hinge, which includes a window frame connection seat, a window sash connection seat, and a connecting arm assembly. The window frame connection seat and the window sash connection seat are connected by the connecting arm assembly for opening and closing. The window frame connection seat is movably provided with an adjustment stopper, and at least a portion of the connecting arm assembly is blocked by the adjustment stopper to limit the position. By changing the relative position of the adjustment stopper and the window frame connection seat, the position where the connecting arm assembly blocks the adjustment stopper is changed, thereby limiting the maximum opening angle of the window sash connection seat. This concealed hinge has a window frame connection seat with an adjustment stopper. By changing the relative position of the adjustment stopper and the window frame connection seat, the adjustment stopper blocks different positions of the connecting arm assembly, thereby limiting the maximum opening angle of the window sash connection seat, thereby improving the versatility of the product.

[0003] The applicant believes that the patent has the following defects:

[0004] 1. When installing the window sash, there is no positioning structure, which makes it easy to deviate during installation;

[0005] 2. There is no structure for adjusting the height of the window sash in the window sash installation structure;

[0006] 3. After installing the window sash, the joint between the window sash and the window needs to be adjusted. This patent does not have a structure for adjusting the spacing. Utility Model Content
